Parental attitudes, attachment styles, social networks, and psychological processes in autism spectrum disorders: a cross-cultural perspective.

In this study the authors used a cross-cultural approach to examine parental attitudes, attachment styles, social networks, and some of the psychological processes involved in Autism Spectrum Disorders (ASD). Fifty-two children (aged 4-11 years) took part in the study: 30 Italians (15 with ASD and 15 controls) and 22 Cubans (11 with ASD and 11 controls). Findings indicated significant differences between the two cultural groups in terms of the structure of the children's social network and parental attitudes toward their children.

Distinct pathways of neural coupling for different basic emotions.

Emotions are complex events recruiting distributed cortical and subcortical cerebral structures, where the functional integration dynamics within the involved neural circuits in relation to the nature of the different emotions are still unknown. Using fMRI, we measured the neural responses elicited by films representing basic emotions (fear, disgust, sadness, happiness). The amygdala and the associative cortex were conjointly activated by all basic emotions.

The Hurst exponent of cardiac response to positive and negative emotional film stimuli using wavelet.

We examined the Hurst exponent of heart rate time series and its relation with the subjective measures of valence and arousal in two groups of subjects. The electrocardiogram (ECG) and the subjective valence and arousal were measured during the administration of emotional film stimuli (happiness, sadness, anger and fear). The results showed that there is a difference in the Hurst exponent for the happiness and sadness conditions but not between the negative emotion conditions (sadness, anger and fear).

Long-term memory for traumatic events: experiences and emotional reactions during the 2000 flood in Italy.

The authors investigated how people remember real-life traumatic events. Adult residents (N = 145) of an Italian community that was flooded in fall of 2000 completed a questionnaire 3 years after the flood. Respondents briefly recounted their personal experiences with the flood and answered questions about emotional reactions to the flood, appraisal processes, and disaster exposure.

EEG phase synchronization during emotional response to positive and negative film stimuli.

In the present study the patterns of interdependency between different brain regions were investigated as volunteers looked at emotional and non-emotional film stimuli. The main goal was to evaluate the emotion-related differences and to check their consistency during the elaboration of the same type of stimuli in repeated presentations. A measure called synchronization index (SI) was used to detect interdependencies in EEG signals.
