Abstract
Introduction Prospective memory (PM) is the ability to remember future intentions, and PM function is closely related to independence in daily life, particularly in patients with temporal lobe epilepsy (TLE). As PM involves various cognitive components of attention, working memory, inhibition and other executive functions, this study investigated how TLE may affect PM components and the underlying neural mechanisms. Methods Sixty-four subjects were recruited, including 20 refractory TLE patients, 18 well-controlled TLE patients and 26 age-matched healthy controls. A set of neuropsychological tests was administered to assess specific brain functions. An event-related potential (ERP) task was used to further explore how PM and its components would be differentially affected in the two TLE types. Results Our findings revealed that: (1) refractory TLE patients scored lower than the healthy controls in the digit span, Verbal Fluency Test and Symbol Digit Modalities Test; (2) refractory TLE patients exhibited impaired PM performance and reduced prospective positivity amplitudes over the frontal, central and parietal regions in ERP experiments when compared to the healthy controls; and (3) decreased P3 amplitudes in the nogo trials were observed over the frontal-central sites in refractory but not in well-controlled TLE patients. Discussion To our knowledge, this is the first ERP study on PM that has specifically identified PM impairment in refractory but not in well-controlled TLE patients. Our finding of double dissociation in PM components suggests that inhibition dysfunction may be the main reason for PM deficit in refractory TLE patients. The present results have clinical implications for neuropsychological rehabilitation in TLE patients.

Abstract
INTRODUCTION Prospective memory has received relatively little attention from a clinical perspective, yet it is an important part of daily functioning. Executive functions have been linked with prospective memory abilities, and age differences are found in both executive functions and prospective memory. The purpose of this study was to investigate whether age cohort differences in prospective memory abilities are mediated by executive functions, specifically inhibition. METHOD Participants (N = 108) consisted of young adults (n= 53) and older adults (n= 55) without any neurocognitive impairment. Participants completed a clinical interview and a battery of neuropsychological tests that included the Mini-Mental Status Exam-2 Standard Version (MMSE-2-SV), the Wisconsin Card Sorting Test-64 (WCST-64), the Delis-Kaplan Executive Functioning System Color-Word Interference Test (D-KEFS CWIT), and the Virtual Kitchen Protocol (VKP). RESULTS Young adults had higher prospective memory scores than older adults. Inhibition (i.e., D-KEFS CWIT) mediated the relationship between age cohort and prospective memory, while cognitive flexibility did not mediate the relationship. CONCLUSIONS Older adults may have diminished inhibition abilities that may negatively affect their ability to complete prospective memory tasks.

Virtual Reality Training of Social Skills in Adults with Autism Spectrum Disorder: An Examination of Acceptability, Usability, User Experience, Social Skills, and Executive Functions.

Abstract
Poor social skills in autism spectrum disorder (ASD) are associated with reduced independence in daily life. Current interventions for improving the social skills of individuals with ASD fail to represent the complexity of real-life social settings and situations. Virtual reality (VR) may facilitate social skills training in social environments and situations similar to those in real life; however, more research is needed to elucidate aspects such as the acceptability, usability, and user experience of VR systems in ASD. Twenty-five participants with ASD attended a neuropsychological evaluation and three sessions of VR social skills training, which incorporated five social scenarios with three difficulty levels. Participants reported high acceptability, system usability, and user experience. Significant correlations were observed between performance in social scenarios, self-reports, and executive functions. Working memory and planning ability were significant predictors of the functionality level in ASD and the VR system's perceived usability, respectively. Yet, performance in social scenarios was the best predictor of usability, acceptability, and functionality level. Planning ability substantially predicted performance in social scenarios, suggesting an implication in social skills. Immersive VR social skills training in individuals with ASD appears to be an appropriate service, but an errorless approach that is adaptive to the individual's needs should be preferred.

Abstract
EPELI (Executive Performance in Everyday LIving) is a recently developed gaming tool for objective assessment of goal-directed behavior and prospective memory (PM) in everyday contexts. This pre-registered study examined psychometric features of a new EPELI adult online version, modified from the original child version and further developed for self-administered web-based testing at home. A sample of 255 healthy adults completed EPELI where their task was to perform household chores instructed by a virtual character. The participants also filled out PM-related questionnaires and a diary and performed two conventional PM tasks and an intelligence test. We expected that the more "life-like" EPELI task would show stronger associations with conventional PM questionnaires and diary-based everyday PM reports than traditional PM tasks would do. This hypothesis did not receive support. Although EPELI was rated as more similar to everyday tasks, performance in it was not associated with the questionnaires and the diary. However, there were associations between time-monitoring behavior in EPELI and the traditional PM tasks. Taken together, online adult-EPELI was found to be a reliable method with high ecological face validity, but its convergent validity requires further research.
