Föreliggande arbete är en experimentell studie som genomfördes vid Spädbarnslabbet, Uppsala Universitet. Undersökningsgruppen bestod av 10-månader gamla barn (n=33) och deras föräldrar. På en dataskärm fick barnen titta på stimuli i form av ljuspunktsanimering av mänsklig rörelse. Barnens titt-tid och pupilldilation registrerades. Det finns i tidigare forskningsresultat belägg för att normalutvecklade barn har en känslighet för biologisk rörelse men detta är inte tidigare studerat med hjälp av pupillometri. I studien ingick också att föräldrarna till barnen i undersökningsgruppen fyllde i ett självskattningsformulär för symtom inom autismspektrum. Syftet med studien var att undersöka om små barns känslighet för biologisk rörelse går att mäta med pupillometri samt att kartlägga om individuella skillnader i känslighet för biologisk rörelse var relaterat till graden av symtom inom autismspektrum hos föräldrarna. Hypoteserna som testades var dels att barnen i undersökningsgruppen var känsliga för biologisk rörelse och att detta skulle visa sig i termer av pupilldilation dels att det skulle finnas ett negativt samband mellan föräldrars självskattning av symtom inom autismspektrum och deras barns känslighet för biologisk rörelse. Resultaten visade att barngruppen som helhet var känslig för biologisk rörelse och att pupillometri var ett användbart mätinstrument för att mäta detta. Resultaten visade inte något samband mellan barnens känslighet för biologisk rörelse och föräldrarnas självskattade symtom inom autismspektrumområdet. Vi fann däremot ett oväntat negativt samband mellan barnens känslighet för biologisk rörelse och familjens socioekonomiska status.   Slutsatsen av denna studie är att pupillometri är en användbar datainsamlingsmetod för att studera små barns känslighet för biologisk rörelse. Något negativt samband mellan barnens känslighet för biologisk rörelse och föräldrarnas symtom inom autismspektrum framkom inte denna studie.

Background: There is presently a lack of consistency in research designed to measure executive functioning (EF) in autism that may be attributable to lack of homogeneity or comorbid conditions (i.e. learning disability or additional diagnosis) in test samples. Aim: A systematic review focused on a subset of EF (verbal fluency: VF) was conducted, using only studies of high-functioning individuals with autism (HFA) without an additional diagnosis or learning disability. An empirical study was conducted comparing the executive functioning profile of individuals with HFA and typically developed (TD) individuals. Method: For the systematic review, 16 studies met the specified inclusion criteria, depicting 15 semantic (category), 14 phonological (letter), and 6 switching (categories) VF tasks. In order to assess potential bias, the available VF information of the included papers was scrutinised by the author and an independent clinical practitioner. For the empirical paper, 22 HFA and 22 TD participants (mean age = 28, range = 17-73, 52% male) without a comorbid condition, learning disability or brain injury completed three subtests from the WAIS-IV (vocabulary, block design and digit span) and all subtests of the Delis–Kaplan Executive Functioning System (D-KEFS). Results: For the systematic review, a minority of semantic and phonological VF studies reported a significant difference between typically developed and HFA populations. Five of the six semantic switching studies reported a significant difference between groups. All papers included were of good or adequate quality and inter-rater reliability was high. For the empirical paper, the HFA group performed significantly poorer on the switching condition of the design fluency task, semantic conditions of the verbal fluency task and on the word context task overall. No other significant differences were observed. Summary: Although the systematic review concluded that there was insufficient evidence to support that disfluency can be attributed to autistic symptomology, the empirical study found that the HFA group performed poorer than TD in semantic VF and other subtests designed to measure generating novel ‘imaginative’ ideas, without visual cues to aid performance. The deficit on these subtests was increased when there was the added condition requiring the participant to switch between newly formed concepts. Conclusions: Although in VF, results are mixed, the empirical study demonstrates that even in a group of high-functioning individuals there are still measurable differences in EF between TD and HFA samples that may not be apparent through more general cognitive testing. Implications for using a neuropsychological profile for adults with HFA are discussed.

Little is known about the factors involved in parents’ with a child with autism spectrum disorders (ASD) decisions to visit a community outing with their family. The purpose of this research is to describe the factors that families consider when making a decision to visit a museum of science with their child with ASD. Data were analyzed based on data from a previous study in which observations and interviews were completed in order to describe the experiences of nine children and their families visiting a science museum. The findings indicated that families considered their child and his/her age and abilities, the community environment, and the features of the activities in the community space as a family when deciding whether their child was ready to visit the museum. Additionally, parents appeared to consider their available strategies for use while in the community when making readiness decisions. The information learned in this study may aid families who are trying to appraise whether their child is ready for a family community outing. Additionally, findings from this research may benefit museums interested in creating inclusive experiences for families with a child with ASD. Recommendations are provided for future research in the area of readiness for community outings for families with a child with ASD.

Prisoners have high rates of physical and mental morbidity and of re-offending. There have been concerns that autism spectrum disorders (ASDs) may be overrepresented and under-diagnosed in this population. The aims of this study were to examine the effectiveness of an instrument which was developed to screen for ASDs in prisons and to establish whether male Scottish prisoners differ from community controls with respect to facial emotion recognition, as measured by behavioural testing, and differ on a neural basis while performing complex social judgements, as measured using functional magnetic resonance imaging (fMRI). A total of 2458 prisoners (approximately 40% of the convicted prison population) were examined using the screening tool, of whom a further 127 were interviewed in depth and were assessed for facial emotion recognition ability. FMRI was used to examine haemodynamic changes in a small sample of liberated prisoners (9) during a social judgement (approachability) versus control (gender judgments) task. The screening tool had poor sensitivity (28.6%) and specificity (75.6%) and was not effective or useful in screening for ASDs in this population. Significant deficits in negative facial emotion recognition were found in the prisoner group in comparison with age- and sex-matched community controls. Region of interest analysis of fMRI data in the bilateral amygdala revealed significantly greater activation in the left amygdala in ex-prisoners versus controls during the social judgement task. The identification of these abnormalities in facial emotion recognition and social judgement are in keeping with current literature on antisocial populations. They may offer the opportunity for development of interventions aimed at reducing re-offending in the future.
