    High-frequency heart rate variability and cortico-striatal activity in men and women with social phobia2009Inngår i: NeuroImage, ISSN 1053-8119, E-ISSN 1095-9572, Vol. 47, nr 3, s. 815-20Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Identifying brain systems that regulate or modulate autonomic nervous system functions may identify pathways through which psychosocial factors can influence health and disease. Reduced high-frequency heart rate variability (HF-HRV) characterizes anxiety disordered patients and is predictive of adverse myocardial events. Sex differences in the prevalence of anxiety disorders and cardiac diseases implicate the possibility of sex specific neural regulation of HF-HRV. We investigated the correlation between HF-HRV and regional cerebral blood flow (rCBF) in 28 subjects (15 women) with social phobia undergoing a stressful public speaking task. Regional CBF was measured with [(15)O] water positron emission tomography. Stress induced rCBF correlated positively with HF-HRV in the right supra genual anterior cingulate cortex Brodmann's area (BA) 32, the right head of the caudate nucleus and bilaterally in the medial prefrontal cortex (BA10), extending into the dorsolateral prefrontal cortex (BA46) in the left hemisphere. Men showed larger positive co-variation in the caudate than women. These findings underscore the importance of the emotional division of the anterior cingulate cortex, the prefrontal cortex and the striatum in cardiovagal activity. The study replicates and extends results from published functional neuroimaging studies on cardioregulatory or modulatory areas in healthy subjects to men and women with social phobia. Moreover, caudate functions, possibly related to dopaminergic neurotransmission, have sexually dimorphic effects on vagal modulation of the heart.

    FJÄLLETS KÄNSLOMÄSSIGA OCH SYMBOLISKA BETYDELSE FÖR DET SAMISKA FOLKET2009Independent thesis Basic level (degree of Bachelor), 30 poäng / 45 hpOppgave
    Abstract [sv]

    Kulturer bestäms och formas av de symboler de använder och vördar och en människas identitet formas delvis av att hon initieras i en kulturs specifika symbolsystem. Symbolerna vänder sig till både våra intellekt, känslor samt våra andliga liv. Genom att använda Pietikainens modifiering av Jungs teori kring arketyper till att förstås som symboliska former så kan ett beskrivande värde uppnås gällande att närma sig människans mentala processer. Uppsatsens syfte är att visa exempel som illustrerar och kan öka förståelsen för vilken symbolisk och känslomässig betydelse fjället har för det samiska folket, i det här fallet representerat av fem personer med samiskt ursprung.   Utifrån ett hermeneutiskt perspektiv har intervjuer gjorts och 17 teman utkristalliserats varav fyra visat sig vara framträdande. Fjällets känslomässiga och symboliska betydelse verkar främst vara kulturellt betingat och fungerar som ett gemensamt minne i den samiska kulturen, utvecklat över generationer. Ett minne som tillskriver fjället starka personifierade egenskaper.

    Intimate partner violence in Europe: design and methods of a multinational study.: La violencia de pareja en Europa: diseño y métodos de un estudio multinacional2013Inngår i: Gaceta Sanitaria, ISSN 0213-9111, E-ISSN 1578-1283, Vol. 27, nr 6, s. 558-561Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective To describe the design, methods, procedures and characteristics of the population involved in a study designed to compare Intimate Partner Violence (IPV) in eight European countries.

    Methods Women and men aged 18–65, living in Ghent-Belgium (n = 245), Stuttgart-Germany (n = 546), Athens-Greece (n = 548), Budapest-Hungary (n = 604), Porto-Portugal (n = 635), Granada-Spain (n = 138), Östersund-Sweden (n = 592), London-United Kingdom (n = 571), were sampled and administered a common questionnaire. Chi-square goodness of fit and five-age strata population fractions ratios for sex and education were computed to evaluate samples' representativeness.

    Results Differences in the age distributions were found among women from Sweden and Portugal and among men from Belgium, Hungary, Portugal and Sweden. Over-recruitment of more educated respondents was noted in all sites.

    Conclusion The use of a common research protocol with the same structured questionnaire is likely to provide accurate estimates of the general population IPV frequency, despite limitations in probabilistic sampling and restrictions in methods of administration.

    Higher- and lower-order personality traits and cluster subtypes in social anxiety disorder.2020Inngår i: PLoS ONE, E-ISSN 1932-6203, Vol. 15, nr 4, artikkel-id e0232187Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Social anxiety disorder (SAD) can come in different forms, presenting problems for diagnostic classification. Here, we examined personality traits in a large sample of patients (N = 265) diagnosed with SAD in comparison to healthy controls (N = 164) by use of the Revised NEO Personality Inventory (NEO-PI-R) and Karolinska Scales of Personality (KSP). In addition, we identified subtypes of SAD based on cluster analysis of the NEO-PI-R Big Five personality dimensions. Significant group differences in personality traits between patients and controls were noted on all Big Five dimensions except agreeableness. Group differences were further noted on most lower-order facets of NEO-PI-R, and nearly all KSP variables. A logistic regression analysis showed, however, that only neuroticism and extraversion remained significant independent predictors of patient/control group when controlling for the effects of the other Big Five dimensions. Also, only neuroticism and extraversion yielded large effect sizes when SAD patients were compared to Swedish normative data for the NEO-PI-R. A two-step cluster analysis resulted in three separate clusters labelled Prototypical (33%), Introvert-Conscientious (29%), and Instable-Open (38%) SAD. Individuals in the Prototypical cluster deviated most on the Big Five dimensions and they were at the most severe end in profile analyses of social anxiety, self-rated fear during public speaking, trait anxiety, and anxiety-related KSP variables. While additional studies are needed to determine if personality subtypes in SAD differ in etiological and treatment-related factors, the present results demonstrate considerable personality heterogeneity in socially anxious individuals, further underscoring that SAD is a multidimensional disorder.

    Är generation Y en samhällsentreprenöriell generation?2014Inngår i: Samhällsentreprenörskap: samverkan för lokal utveckling / [ed] Yvonne von Fredrichs, Malina Gawell, Joakim Wincent, Östersund: Mittuniversitetet , 2014, s. 149-166Kapittel i bok, del av antologi (Fagfellevurdert)
    Abstract [sv]

    Landsbygden står inför stora utmaningar. I en allt mer konkurrensutsatt värld utmanas etablerade modeller i välfärdssamhället och bland annat har serviceutbudet och möjligheterna till försörjning minskat på den svenska landsbygden. Samtidigt vill många bo kvar då landsbygden upplevs bidra med livskvalitet samt närhet till kulturella och sociala sammanhang. Därför engagerar sig många människor för att skapa förutsättningar för att det ska vara möjligt att arbeta och bo även utanför större städer. Samhällsentreprenörskap har kommit att bli ett attraktivt alternativ för att bryta nedåtgående trender i lokalsamhället och för att finna nya lösningar för en hållbar utveckling. Inom ramen för forskningsprojektet Societal Entrepreneurship in Sparsely Populated Areas (SESPA), som bedrivits vid Mittuniversitetet mellan åren 2010- 2014, har forskare från olika ämnesdiscipliner studerat samhällsentreprenörskapets roll i den lokala utvecklingen. SESPA:s forskning har kunnat genomföras med hjälp av stöd från EU:s regionala strukturfondsprogram samt Mittuniversitetet och Länsstyrelserna i Jämtland och Västernorrland. Forskningen har bedrivits i nära samspel med företrädare från det lokala näringslivet, ideella organisationer samt offentliga institutioner. De studier som presenteras i denna antologi visar att samhällsentreprenörskapet kan ta sig många olika uttryck. Det rör sig dock genomgående om människors engagemang, idérikedom och aktiva handlingar. Det rör sig om individer, kreativitet och organiserande processer. Och att alla initiativ har sin egen kontext. Syftet med den här boken är dels att sprida resultat från den forskning om samhällsentreprenörskapets roll för den lokala utvecklingen som utvecklats inom ramen för SESPA men även att bidra till en ökad förståelse om fenomenet samhällsentreprenörskap ur ett välfärdssamhälles perspektiv. Vår förhoppning är att boken ska bidra till reflektion men även fungera som inspiration till fler samhällsentreprenöriella initiativ.

    When having two names facilitates lexical selection: Similar results in the picture-word task from translation distractors in bilinguals and synonym distractors in monolinguals2018Inngår i: Cognition, ISSN 0010-0277, E-ISSN 1873-7838, Vol. 171, nr February 2018, s. 151-171Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We report five experiments using the picture-word task to examine lexical selection by comparing the effects of translation distractors in bilinguals and synonym distractors in monolinguals. Three groups of bilinguals named objects in their L1 or L2, and English monolinguals named objects using common names (e.g., DOG = “dog”) or, in a novel manipulation, using synonymous alternative names (e.g., DOG = “hound”, GLASSES = “spectacles”). All studies produced strikingly similar results. When bilinguals named in L1, there was a small facilitation effect from translation distractors, but larger facilitation when they named in L2. When monolinguals produced common names, there was no reliable effect from synonym distractors, but facilitation when they produced alternative names. (There were also strong identity facilitation effects in all naming conditions.) We discuss the relevance of these results for the debate concerning the role of competition in lexical selection and propose that for speech production there are direct facilitatory connections between the lexical representations of translations in bilinguals (and between synonyms in monolinguals). The effects of synonyms in monolinguals appear to “simulate” the effects found for translations in bilinguals, which suggest that there are commonalities in monolingual and bilingual lexical selection.

    When your heart is in your mouth: the effect of second language use on negative emotions2019Inngår i: Cognition & Emotion, ISSN 0269-9931, E-ISSN 1464-0600, Vol. 33, nr 6, s. 1284-1290Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Research on bilingualism and emotions has shown stronger emotional responses in the native language (L1) compared to a foreign language. We investigated the potential of purposeful second language (L2) use as a means of decreasing the experience of psychological distress. Native Swedish speakers read and answered questions about negative and neutral texts in their L1 (Swedish) and their L2 (English) and were asked to rate their level of distress before or after the questions. The texts and associated questions were either written in the same (within-language), or different languages (cross-language). We found that within-language trials when the text was written in participants’ native language (Swedish–Swedish) resulted in an increase of distress, whilst cross-language trials (Swedish–English) resulted in a decrease of distress. This implies that purposeful second language use can diminish levels of distress experienced following a negative event encoded in one's first language.

    Reading habits and emotional vocabulary in adolescents2020Inngår i: Educational Psychology, ISSN 0144-3410, E-ISSN 1469-5820Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Previous research has found that reading increases overall vocabulary size, and that reading fiction, specifically, is associated with higher levels of empathy and better perspective-taking skills. The current study investigated a potential link between reading habits and emotional vocabulary in particular, to assess whether the link between reading and empathy could be specifically related to emotion words. A total of 415 Swedish secondary and upper secondary school students were asked to generate words in various emotional categories, and to report their reading habits. Generally, females produced more words than males. For all participants, the largest amount of words was produced in the neutral, followed by positive, then the negative category. Crucially, the frequent readers produced more emotional words than the less frequent readers, suggesting that reading habits are associated with emotional vocabulary. We discuss the implications of these findings for the understanding of the link between reading and emotional competence.

    No foreign language effect in decision making for culturally influential second languages2019Konferansepaper (Fagfellevurdert)
    Abstract [en]

    We report two experiments investigating the foreign language effect (FLe) for culturally influential languages. Across two experimental paradigms, we found no FLe for Swedish participants when using their second language English. This highlights the limitations of the FLe and suggests that it may not be as robust as previously thought.

    Vittnesintervjuer genom fri återgivning ger omfattande vittnesmål även under stress.2012Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Kognitiva intervjumetoden (KI) ger vittnesmål med hög frekvens och korrekthet av detaljrapporteringar, även från stressade vittnen. Då KI kräver utbildning i metoden och att den är tidskrävande är ett problem inom polisväsendet. Studien avsåg att undersöka om det initiala momentet inom KI, fri återgivning, är en effektiv intervjumetod för att erhålla vittnesmål med hög frekvens av korrekta detaljrapporteringar även när vittnesintervjun genomförs med stressade vittnen. Deltagarna (N =32) randomiserades till kontroll- respektive experimentgrupp och de tittade på ett inspelat butiksrån. Experimentgruppen utsattes därefter för stressmanipulation, varefter samtliga genomgick vittnesintervjuer. Resultatet visade ingen signifikant skillnad mellan grupperna i frekvens och korrekthet av detaljrapporteringen. Resultatet tyder på att fri återgivning är en adekvat metod för vittnesintervjuer i initiala skedet av brottsutredningar. En könseffekt observerades i experimentgruppen för andelen felaktigt rapporterade minnesdetaljer, vilket tyder på en benägenhet för gissningar.

    A link between serotonin-related gene polymorphisms, amygdala activity, and placebo-induced relief from social anxiety2008Inngår i: Journal of Neuroscience, ISSN 0270-6474, E-ISSN 1529-2401, Vol. 28, nr 49, s. 13066-74Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Placebo may yield beneficial effects that are indistinguishable from those of active medication, but the factors underlying proneness to respond to placebo are widely unknown. Here, we used functional neuroimaging to examine neural correlates of anxiety reduction resulting from sustained placebo treatment under randomized double-blind conditions, in patients with social anxiety disorder. Brain activity was assessed during a stressful public speaking task by means of positron emission tomography before and after an 8 week treatment period. Patients were genotyped with respect to the serotonin transporter-linked polymorphic region (5-HTTLPR) and the G-703T polymorphism in the tryptophan hydroxylase-2 (TPH2) gene promoter. Results showed that placebo response was accompanied by reduced stress-related activity in the amygdala, a brain region crucial for emotional processing. However, attenuated amygdala activity was demonstrable only in subjects who were homozygous for the long allele of the 5-HTTLPR or the G variant of the TPH2 G-703T polymorphism, and not in carriers of short or T alleles. Moreover, the TPH2 polymorphism was a significant predictor of clinical placebo response, homozygosity for the G allele being associated with greater improvement in anxiety symptoms. Path analysis supported that the genetic effect on symptomatic improvement with placebo is mediated by its effect on amygdala activity. Hence, our study shows, for the first time, evidence of a link between genetically controlled serotonergic modulation of amygdala activity and placebo-induced anxiety relief.

    Cerebral blood flow changes after treatment of social phobia with the neurokinin-1 antagonist GR205171, citalopram, or placebo2005Inngår i: Biological Psychiatry, ISSN 0006-3223, E-ISSN 1873-2402, Vol. 58, nr 2, s. 132-142Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Evidence is accumulating that pharmacological blockade of the substance P preferring neurokinin-1 (NK1) receptor reduces anxiety. This study compared the effects of an NK1 receptor antagonist, citalopram, and placebo on brain activity and anxiety symptoms in social phobia.

    METHODS: Thirty-six patients diagnosed with social phobia were treated for 6 weeks with the NK1 antagonist GR205171 (5 mg), citalopram (40 mg), or matching placebo under randomized double-blind conditions. GR205171 was administered for 4 weeks preceded by 2 weeks of placebo. Before and after treatment, regional cerebral blood flow (rCBF) during a stressful public speaking task was assessed using oxygen-15 positron emission tomography. Response rate was determined by the Clinical Global Impression Improvement Scale.

    RESULTS: Patients improved to a larger extent with the NK1 antagonist (41.7% responders) and citalopram (50% responders), compared with placebo (8.3% responders). Within- and between-group comparisons showed that symptom improvement was paralleled by a significantly reduced rCBF response to public speaking in the rhinal cortex, amygdala, and parahippocampal-hippocampal regions. The rCBF pattern was corroborated in follow-up analyses of responders and subjects showing large state anxiety reduction.

    CONCLUSIONS: Short-term administration of GR205171 and citalopram alleviated social anxiety. Neurokinin-1 antagonists may act like serotonin reuptake inhibitors by attenuating neural activity in a medial temporal lobe network.

    Genotype over-diagnosis in amygdala responsiveness: affective processing in social anxiety disorder2009Inngår i: Journal of Psychiatry & Neuroscience, ISSN 1180-4882, E-ISSN 1488-2434, Vol. 34, nr 1, s. 30-40Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Although the amygdala is thought to be a crucial brain region for negative affect, neuroimaging studies do not always show enhanced amygdala response to aversive stimuli in patients with anxiety disorders. Serotonin (5-HT)-related genotypes may contribute to interindividual variability in amygdala responsiveness. The short (s) allele of the 5-HT transporter linked polymorphic region (5-HTTLPR) and the T variant of the G-703T polymorphism in the tryptophan hydroxylase-2 (TPH2) gene have previously been associated with amygdala hyperresponsivity to negative faces in healthy controls. We investigated the influence of these polymorphisms on amygdala responsiveness to angry faces in patients with social anxiety disorder (SAD) compared with healthy controls.

    METHODS: We used positron emission tomography with oxygen 15-labelled water to assess regional cerebral blood flow in 34 patients with SAD and 18 controls who viewed photographs of angry and neutral faces presented in counterbalanced order. We genotyped all participants with respect to the 5-HTTLPR and TPH2 polymorphisms.

    RESULTS: Patients with SAD and controls had increased left amygdala activation in response to angry compared with neutral faces. Genotype but not diagnosis explained a significant portion of the variance in amygdala responsiveness, the response being more pronounced in carriers of s and/or T alleles.

    LIMITATIONS: Our analyses were limited owing to the small sample and the fact that we were unable to match participants on genotype before enrollment. In addition, other imaging techniques not used in our study may have revealed additional effects of emotional stimuli.

    CONCLUSION: Amygdala responsiveness to angry faces was more strongly related to serotonergic polymorphisms than to diagnosis of SAD. Emotion activation studies comparing amygdala excitability in patient and control groups could benefit from taking variation in 5-HT-related genes into account.

    The Effect of Plants on Individuals' Stress Level in an Indoor Work Environment2010Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Many instances of sick leave can be linked to diseases caused by stress. An efficient way to counter the negative effects of stress is coping. However, trying to fit coping activities into an already busy schedule can be stressful in itself. Therefore it is interesting to study passive stress-reducing methods, for instance interaction with nature. This paper studied the effect of the presence of plants in a work-like environment on the stress level of 30 participants divided equally in a control group and a test group by measuring their heart rate. A factorial analysis of variance and a multivariate analysis of variance were used to analyze the data. Despite the heart rate of the control group being on an average 5 beats per minute higher than the test group, the difference was found not to be statistically significant. An explanation for this could be the poor reliability of heart rate as a measure of stress.

    En sund process eller en osund stagnation: En kvalitativ studie som beskriver skydds- och riskfaktorer för barn placerade i familjehem.2011Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Syftet med denna studie var att undersöka och tydliggöra vissa skydds- och riskfaktorer som finns för barn placerade i familjehem. Den ansats som användes till denna studie var kvalitativ och urvalet till denna skedde genom kvoturval. Efter urvalet genomfördes halvstrukturerade intervjuer med fem stycken respondenter. Genom intervjuerna fick jag en tydligare bild av vilka faktorer som kunde inverka positivt eller negativt för de placerade barnen. Betydelsen av att familjehem samtalade med barn påvisades och genom detta bekräftades och hördes de placerade barnen. Det framgick tydligt att socialsekreterare ville ha mer tid för att kunna hålla regelbundna kontakter till barnen samt att kunna ge adekvat handledning till familjehemmen. Om socialsekreterarna kunde upprätthålla goda och täta kontakter gav det i flesta fall gensvar på ett positivt sätt utav vården, tilliten hos barnen ökade även gentemot socialsekreteraren. Slutsatsen är att tiden är en bristvara som blir en riskfaktor i hela vårdprocessen. Barnen är beroende av goda relationer till både socialsekreterare och familjehem, de är även i stor utsträckning till gagn för de placerade barnen om de biologiska föräldrarna är delaktig i vården. Således kan vi se vården som ett samspel mellan olika faktorer.

    Competitive Versus Non-Competitive Goals in Group Decision-Making2014Inngår i: Small Group Research, ISSN 1046-4964, E-ISSN 1552-8278, ISSN 1046-4964, Vol. 45, nr 4, s. 451-464Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study presents results from a group decision task in which groups were assigned either a competitive or a non-competitive goal. A total of 20 groups were tasked with putting together a relay team either with the goal to maximize the chance to win or with the goal to maximize the sense of community. Interaction process analysis revealed that there were more positive reactions in groups with the non-competitive goal. Analysis of the content of the conversations showed all groups to go beyond information given about the target persons. Attributes associated with the stereotype dimensions of competence and warmth were used to characterize the persons who were to be included or excluded on the relay teams. Groups with a competitive goal applied both positive and negative attributes, whereas groups with a non-competitive goal applied only positive attributes. The results suggest that stereotypes are applied to legitimize decisions about inclusion and exclusion.

    Sjukvårdspersonal och polis: - föreligger skillnad i empati inom den offentliga sektorn?2013Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Syftet med studien var att se om det förelåg skillnad i empati inom yrken i den offentliga sektorn, mätt på två yrkeskategorier, som har för uppgift att hjälpa människor i samhället. 344 deltagare deltog i studien (n=180, kvinnor, n =162, män, n=2, okänt kön). Fördelade i tre olika grupper, polis (n=154), sjuksköterska/undersköterska (n=119) och kontrollgrupp (n=71). Deltagarna var mellan 22-64 år gamla. Signifikant skillnad påvisades i empati som mäter emotionell förståelse, sympatisk fysiologisk affekt, altruism och bedömning av ett känslomässigt tillstånd. Men även där alla frågorna slagits samman till en variabel förelåg en signifikant skillnad. Sjuksköterskor/undersköterskor hade mer empati enligt självskattningsskalan som användes i samtliga tidigare nämnda mätta empatier. Polis hade lägst medelvärde i tidigare nämnda mätta empatier förutom i emotionell förståelse, där kontrollgruppen påvisade lägst resultat. Studien visade även att emotionell förståelse hade ett positivt samband med ålder hos poliser, men att perception av ett emotionellt tillstånd hade ett negativt samband med ökad ålder i samma yrkesgrupp.

    Integrating Horticulture into the Vocational Rehabilitation Process of Individuals with Exhaustion Syndrome (Burnout): A Pilot Study.2009Inngår i: International Journal of Disability Management Research, ISSN 1833-8550, Vol. 3, nr 2, s. 39-53Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This pilot study was intended to examine and to document whether the use of the garden environment and the activities that make up horticulture could be considered a possible method to be used in the vocational rehabilitation of persons sick-listed due to high levels of stress. The study is based on a theoretical (four-step) model using horticulture and the garden environment to provide the foundation of vocational rehabilitation for individuals with prolonged fatigue, chronic fatigue and burnout. The general interpretation is that the results are positive and promising but that further research is needed and should be pursued to examine what causal relationship(s) exist between the garden environment and the reduction of arousal levels; the effectiveness of pursuing this VR process for persons sick listed for stress-related complaints.

    Parenting difficult children and adolescents2018Inngår i: Parenting: Empirical advances and intervention resources / [ed] L Benedetto & M Ingrassia, Croatia: InTech, 2018, s. 59-82Kapittel i bok, del av antologi (Fagfellevurdert)
    Abstract [en]

    Parenting is generally conceived as a unidirectional construct in which parents arethought to be the direct or indirect cause of different child outcomes. Children whoexhibit problematic behavior, who display hurtful and uncaring behavior toward othersor who are aggressive or turn to delinquency when they reach adolescence are oftenviewed as the product of insufficient parental competence (i.e., nurture) in addition toinherited genetic predisposition (i.e., nature). Competent parental behavior, on the otherhand, counteracts the development of callous-unemotional traits and disruptive conductby promoting the internalization of prosocial and normative behavior. However, empiricalevidence consistently shows that the general behavioral patterns of parents and childrenbecome interdependent and mutually reinforcing during childhood. Parents withlow parental competence, who interact with temperamentally difficult children, consistentlycreate coercive exchanges that produce escalations in child oppositional andaggressive behavior, subsequently increasing the likelihood of continued harsh parentingstrategies. Therefore, early prevention and intervention programs must have a systemicapproach and target the parents, the children, and the interaction process itself. Ifthe cycle of harsh, negative, and confrontational interactions is not broken during earlychildhood, there is a risk that coercion settles as a baseline pattern of conduct for futurerelationships.

    The use of a screening device to assess psychopathy in young offenders2012Inngår i: The Spanish Journal of Psychology, ISSN 1138-7416, E-ISSN 1988-2904, Vol. 15, nr 2, s. 724-735Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The aim of this research was to determine to what extent a psychopath screening device (the APSD) is useful in forensic assessments to predict general and violent offending. For this purpose, a cross-sectional study was done and 238 young people serving a sentence were assessed. The gold standard instrument used to measure psychopathy was the Psychopathy Checklist: Youth Version (PCL:YV; Forth, Kosson & Hare, 2003). The results indicate that the association found between the screening device scores and several indicators of risk is low if compared with those obtained with the PCL:YV, suggesting that it is less useful as a tool in order to predict offending or violent offences. However, an Area Under the Curve of .784 and a validity index of 62.5 support its use as a screening device or as a preliminary approach to assess psychopathy in this population. The usefulness of this instrument to make assessments with young people in the forensic setting is discussed.

    The association between maltreatment in childhood and criminal convictions to age 24: A prospective study of a community simple of males from disadvantaged neighbourhoods2012Inngår i: European Child and Adolescent Psychiatry, ISSN 1018-8827, E-ISSN 1435-165X, Vol. 21, nr 7, s. 403-413Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    While many studies have observed a positive association between maltreatment in childhood and criminality in adolescence and adulthood, others have failed to detect such an association. Most studies, however, have not examined different types of maltreatment, nor taken account of other family and childhood factors that are predictive of criminality. Using data from a prospective, longitudinal investigation of a community sample of 1,037 males, we calculated hierarchical logistic regression models to estimate the associations of boys' self-reports of neglect, emotional abuse, and physical abuse at ages 10 and 12, with convictions for criminal offenses from age 12 to 24, after taking account of conduct problems, hurtful and uncaring behaviours (HUB), and parent's criminality. At ages 10 and 12, boys' reports of neglect, emotional abuse, and physical abuse, were not associated with criminal convictions for non-violent or for violent crimes from age 12 to 24. Among boys who did not engage in HUB towards others reports of emotional abuse were associated with subsequent criminality, while this association disappeared among the boys engaging in such behaviours. In this community sample of males, levels of each type of maltreatment were low and there were no direct associations with subsequent criminal convictions. The findings add to emerging evidence that the characteristics of the child and parents, as well as the type of maltreatment modify the association with future criminal offending.

    Can you hear my age?: Influences of speech rate and speech spontaneity on estimation of speaker age2015Inngår i: Frontiers in Psychology, ISSN 1664-1078, E-ISSN 1664-1078, Vol. 6, artikkel-id 978Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Cognitive hearing science is mainly about the study of how cognitive factors contribute to speech comprehension, but cognitive factors also partake in speech processing to infer non-linguistic information from speech signals, such as the intentions of the talker and the speaker’s age. Here, we report two experiments on age estimation by “naïve” listeners. The aim was to study how speech rate influences estimation of speaker age by comparing the speakers’ natural speech rate with increased or decreased speech rate. In Experiment 1, listeners were presented with audio samples of read speech from three different speaker age groups (young, middle aged, and old adults). They estimated the speakers as younger when speech rate was faster than normal and as older when speech rate was slower than normal. This speech rate effect was slightly greater in magnitude for older (60–65 years) speakers in comparison with younger (20–25 years) speakers, suggesting that speech rate may gain greater importance as a perceptual age cue with increased speaker age. This pattern was more pronounced in Experiment 2, in which listeners estimated age from spontaneous speech. Faster speech rate was associated with lower age estimates, but only for older and middle aged (40–45 years) speakers. Taken together, speakers of all age groups were estimated as older when speech rate decreased, except for the youngest speakers in Experiment 2. The absence of a linear speech rate effect in estimates of younger speakers, for spontaneous speech, implies that listeners use different age estimation strategies or cues (possibly vocabulary) depending on the age of the speaker and the spontaneity of the speech. Potential implications for forensic investigations and other applied domains are discussed.

    Hypothalamic blood flow correlates positively with stress-induced cortisol levels in subjects with social anxiety disorder2006Inngår i: Psychosomatic Medicine, ISSN 0033-3174, E-ISSN 1534-7796, Vol. 68, nr 6, s. 859-62Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    OBJECTIVE: The adrenal excretion of cortisol in animals is dependent on the production of corticotropin-releasing factor in the paraventricular nucleus of the hypothalamus. The a priori hypothesis of this study was that hypothalamic regional cerebral blood flow (rCBF) would correlate positively with salivary cortisol levels in patients with social anxiety disorder (SAD) during anxiety provocation. Another objective was to evaluate whether salivary cortisol levels correlated with rCBF in other brain areas.

    METHOD: Regional CBF was measured with oxygen-15-labeled water and positron emission tomography during a public speaking task before and after placebo treatment in 12 subjects with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition-defined SAD. Cortisol concentrations in saliva were measured 15 minutes after the task. The a priori hypothesis of a salivary cortisol-dependent activation of the hypothalamus was studied with region-of-interest analysis. In addition, the covariation between rCBF and salivary cortisol was studied in the whole brain using the general linear model.

    RESULTS: The region-of-interest analysis revealed a positive correlation between salivary cortisol and hypothalamic rCBF. In the whole brain analysis, a positive covariation between rCBF and salivary cortisol levels was found in a midbrain cluster encompassing the hypothalamus with its statistical maximum in the mamillary bodies. Negative covariations were observed in the medial prefrontal cortex as well as in the motor and premotor cortices.

    CONCLUSION: Like in animals, stress-induced cortisol excretion in humans may be inhibited by activity in the medial prefrontal cortex and enhanced by activity in the hypothalamus.

    Disentangling the web of fear: amygdala reactivity and functional connectivity in spider and snake phobia2009Inngår i: Psychiatry Research, ISSN 0165-1781, E-ISSN 1872-7123, Vol. 172, nr 2, s. 103-108Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The objective was to study effects of fear on brain activity, functional connectivity and brain-behavior relationships during symptom provocation in subjects with specific phobia. Positron emission tomography (PET) and (15)O water was used to measure regional cerebral blood flow (rCBF) in 16 women phobic of either snakes or spiders but not both. Subjects watched pictures of snakes and spiders serving either as phobic or fear-relevant, but non-phobic, control stimuli depending on phobia type. Presentation of phobic as compared with non-phobic cues was associated with increased activation of the right amygdala and cerebellum as well as the left visual cortex and circumscribed frontal areas. Activity decreased in the prefrontal, orbitofrontal and ventromedial cortices as well as in the primary somatosensory cortex and auditory cortices. Furthermore, amygdala activation correlated positively with the subjective experience of distress. Connectivity analyses of activity in the phobic state revealed increased functional couplings between voxels in the right amygdala and the periamygdaloid area, fusiform gyrus and motor cortex. During non-phobic stimulation, prefrontal activity correlated negatively with amygdala rCBF, suggesting a phobia-related functional decoupling. These results suggest that visually elicited phobic reactions activate object recognition areas and deactivate prefrontal areas involved in cognitive control over emotion-triggering areas like the amygdala, resulting in motor readiness to support fight or flight.
