The degree of pseudoneglect increment positively correlated with perceived stress and negatively correlated with Positive Attitude and Problem-Solving COPE-NIV subscales.ConclusionLockdown-related stress may have contributed to increase leftward bias during quarantine through a greater activation of the right hemisphere. On the other hand, pseudoneglect was decreased for better coping participants, perhaps as a consequence of a more balanced hemispheric activity in these individuals.

BACKGROUND: Videomodeling is an effective technological tool for intervention and rehabilitation of children with autism spectrum disorders in different contexts. OBJECTIVE: The purpose of this paper is to verify whether a videomodeling intervention is effective for the acquisition of social and emotional behaviour and skills of children with ASD using tablet PC. METHODS: One 6-year-old child with ASD, who does not use verbal communication, was involved in a multiple baseline across behaviours design: the independent variable was the videomodeling intervention, instead the dependent variable was the participant behaviour. Intervention was preceded by a pre-session of Functional Communication training. An intersubject analysis was used to evaluate participant percentage of response through the sessions. RESULTS: The participant showed a marked improvement in his emotional skills. The intersubjective analysis carried out shows the sharp increase in response in many target behaviours from the baseline to the intervention phase. A limitation of the study was the lack of time: there were only two inversion sessions, no follow-up evaluation, no generalization and no double-blind study. CONCLUSIONS: It would be interesting for future research to extend it to everyday life scenarios, to enhance generalization in other contexts, involving a larger number of people with ASD.

The Baking Tray Task is an ecological task developed for the assessment of unilateral neglect that can also be used for research on neurotypical participants. In this task, participants are asked to place 16 objects inside a board as evenly as possible. In the case of impaired spatial exploration, consequent to right attentional networks damage, asymmetrical object disposition is observed as more objects are placed on the ipsilesional side (typically the right side). The E-BTT is a technology-enhanced version of the Baking Tray Task, implemented with a software platform, E-TAN, which detects the objects and automatically computes their spatial coordinates. This allows a complement to the traditional scoring methods with new measures to extract richer information from the data. In this study, we focus on neurotypical participants to explore if some new indexes, derived from the literature review on similar tasks, can be applied to BTT and E-BTT for research aims. A principal component analysis (PCA) was then performed to verify if these new indexes reflect some common dimensions. Results indicate the emergence of two principal dimensions: spatiality, which summarizes both laterality and verticality, and quality, which regards the explored space and (dis)organization in placing the items.
