•Assessment tools have progressed from measuring specific components, to more comprehensive assessments.•Performance-based tools, has the potential to include an EF index as part of the test scoring.•Most researchers either chose short versions of the assessment tools to address the subjects' attentional capacities.•Using more than one evaluation method enabled to draw a more precise picture of the function.

Previous studies exhibited differences in sensory processing, motor coordination, metacognitive executive functions (EF-MI), and sleep quality among adults with neurodevelopmental disorders (NDD). This study aims to find relationships between those abilities and organization-in-time, focusing on emotional responses after decreased organization abilities. This is a secondary data analysis of a larger sample from three previous studies conducted in one laboratory. Data were collected from 290 adults; 149 with NDD and 141 sex- and age- (20-50 years) matched controls completed the Adolescent/Adult Sensory Profile, Adult Developmental Coordination Disorder, Adults Behavioral Rating Inventory of Executive Functions, Mini Sleep, and Time Organization and Participation questionnaires. Structural equation model (SEM) analysed relationships and variable prediction. Significant between-group differences were found for all variables; SEM indicated similar paths in both groups. Sensory processing affected EF-MI and sleep quality and significantly correlated with motor coordination, affecting EF-MI; EF-MI affected organization-in-time. Sleep quality significantly affected organization-in-time, affecting emotional responses. Sensory, motor, EF, and sleep differences were associated with decreased organization-in-time abilities of adults with NDD, adversely affecting their emotional well-being. Early detection of such differences and targeted interventions may improve daily functioning and life quality and prevent negative emotional implications.

Individuals with severe mental illnesses (SMI) often have difficulty performing daily activities that require intact executive functions, such as grocery shopping. Performance-based evaluations are valuable but lack the subjects’ viewpoints during task performance. This study aims to combine performance-based observation and cognitive science methods to provide insights regarding real-life behavior and problem-solving in populations with SMI. In this correlational-research study, 42 participants (10 in the SMI group and 32 in the control group) performed the Test of Grocery Shopping Skills (TOGSS) while wearing an eye-tracking device. We hypothesized that patterns in task planning, task-time use, and attention allocation to written information relevant to the task would differ between the groups during the task. The results showed between-group differences in both TOGSS efficiency outcomes (time and redundancy), duration, and number of fixations. An eye-tracking pattern analysis determined between-group differences in scanning patterns of the grocery list but similarities in task planning. The selection process was found to be significantly more accurate and efficient for the control group than for the SMI group. Our findings suggest that a combination of perspectives allows us to better understand the behavior of SMI individuals in a regular daily task.

Purpose: In this study, the assessment tool “Internet and Computer User Profile” questionnaire (ICUP) is presented and validated. It was developed in order to gather information for setting intervention goals to meet current demands. Methods: Sixty-eight subjects aged 23–68 participated in the study. The study group (n = 28) was sampled from two vocational centers. The control group consisted of 40 participants from the general population that were sampled by convenience sampling based on the demographics of the study group. Subjects from both groups answered the ICUP questionnaire. Subjects of the study group answered the General Self- Efficacy (GSE) questionnaire and performed the Assessment of Computer Task Performance (ACTP) test in order to examine the convergent validity of the ICUP. Twenty subjects from both groups retook the ICUP questionnaire in order to obtain test-retest results. Differences between groups were tested using multiple analysis of variance (MANOVA) tests. Pearson and Spearman's tests were used for calculating correlations. Cronbach's alpha coefficient and k equivalent were used to assess internal consistency. Results: The results indicate that the questionnaire is valid and reliable. They emphasize that the layout of the ICUP items facilitates in making a comprehensive examination of the client's perception regarding his participation in computer and internet activities.

Date Presented 03/27/20 This study carried out a performance-based task combined with an eye-tracker device for both a control group and a group of people coping with severe mental illnesses. This was done in order to better understand difficulties in task performance and to deepen OTs’ and cognitive scientists’ understanding of client factor and to identify interventions in the most favorable way for the individual. Preliminary results show a difference between the groups in both observational and objective findings. Primary Author and Speaker: Sivan Regev Contributing Authors: Naomi Josman, Avi Mendelsohn
