Estratégias de resolução de conflitos em adolescentes angolanos e portugueses

Pretendemos estudar situações de conflito interpessoal e sócio-moral e comparar as estratégias de resolução que são escolhidas por adolescentes de contextos culturais diferentes. Participaram no estudo 89 adolescentes, 44 portugueses e 45 angolanos, com idades compreendidas entre os 14 e os 16 anos, distribuídos de forma equivalente pelos dois géneros. Foram construídos quatro dilemas que configuram situações de conflito interpessoal e moral habituais entre adolescentes (humilhação, inveja, rivalidade entre grupos e traição amorosa) e foram utilizadas quatro medidas, atribuição de comportamento e de emoção, perceção de ganhos e antecipação de custos. Os resultados revelaram que a escolha de estratégias de resolução de conflitos interpessoais (agressão física, agressão verbal, indiferença, negociação e outras) é insensível ao género, mas varia inter-medidas nas histórias de inveja e de traição, varia com o conteúdo sócio-moral das situações, sobretudo entre a história de traição amorosa e as outras histórias, e varia inter-culturas também para a história de traição, onde se verificam diferenças estatísticas nas três medidas. Os resultados mostram ainda que os adolescentes têm dificuldade em antecipar os custos associados às estratégias de resolução de conflitos interpessoais, pois optam maioritariamente por não responder a esta questão.

Social perception gaze patterns, symptom severity and resting brain function measured using Arterial Spin Labelling

Autistic spectrum disorder (ASD) is characterised by qualitative alterations in reciprocal social interactions. Some recent studies show alterations in gaze patterns during social perception and rest-functional abnormalities in the ‘social brain network’. This study investigated: i) social perception gaze patterns in children with ASD and controls, ii) the relationship between autism clinical severity and social perception gaze patterns, iii) the relationship between resting cerebral blood flow (rCBF) and social perception gaze patterns. Methods: Nine children with ASD and 9 children with typical development were studied. Eye-tracking was used to detect gaze patterns during presentation of stimuli depicting social scenes. Autism clinical severity was established using the Autism Diagnostic Interview Revised (ADI-R). Arterial spin labelling MRI was used to quantify rCBF. Results: The ASD group looked less at social regions and more at non-social regions than controls. No significant correlation was found between ASD clinical severity and social perception gaze patterns. In the ASD group, gaze behaviour was related to rCBF in the temporal lobe regions at trend level. Positive correlations were found between temporal rCBF and gaze to the face region, while negative correlations were found between temporal rCBF and gaze to non-social regions. Conclusions: These preliminary results suggest that social perception gaze patterns are altered in children with ASD, and could be related to temporal rCBF.

Emotion recognition in multiple sclerosis

The effect of multiple sclerosis (MS) on the ability to identify emotional expressions in faces was investigated, and possible associations with patients’ characteristics were explored. 56 non-demented MS patients and 56 healthy subjects (HS) with similar demographic characteristics performed an emotion recognition task (ERT), the Benton Facial Recognition Test (BFRT), and answered the Hospital Anxiety and Depression Scale (HADS). Additionally, MS patients underwent a neurological examination and a comprehensive neuropsychological evaluation. The ERT consisted of 42 pictures of faces (depicting anger, disgust, fear, happiness, sadness, surprise and neutral expressions) from the NimStim set. An iViewX high-speed eye tracker was used to record eye movements during ERT. The fixation times were calculated for two regions of interest (i.e., eyes and rest of the face). No significant differences were found between MS and HC on ERT’s behavioral and oculomotor measures. Bivariate and multiple regression analyses revealed significant associations between ERT’s behavioral performance and demographic, clinical, psychopathological, and cognitive measures.
