Abstract:Background The present study investigated the influence of emotional contexts on mental flexibility in adults with Prader-Willi syndrome (PWS) using a voluntary task-switching paradigm that was implemented with emotionally valenced pictures. The study aims were to assess whether adults with PWS have impaired switching abilities, whether the deficit is specific to PWS or linked to intellectual disabilities, and the influence of emotional contexts on performance. Method The task-switching performance of 30 adult… Show more
“…Critically, each task needs to be mapped to different response effectors so that the response can be used to infer which task was selected. Probably the most widely used task-to-effector mapping approach is to map each task to one hand (e.g., left index and middle finger = color task; right index and middle finger = letter task) (e.g., Arrington & Logan, 2004 ; 2005 ; Brüning et al, 2020 ; Chevalère et al, 2022 ; Frick et al, 2019 ; Jurczyk et al, 2019 ; Kessler et al, 2009 ; Mayr & Bell, 2006 ).…”
There has been an increasing interest in uncovering the mechanisms underpinning how people decide which task to perform at a given time. Many studies suggest that task representations are crucial in guiding such voluntary task selection behavior, which is primarily reflected in a bias to select task repetitions over task switches. However, it is not yet clear whether the task-specific motor effectors are also a crucial component of task representations when deciding to switch tasks. Across three experiments using different voluntary task switching (VTS) procedures, we show that a greater overlap in task representations with a task-to-finger mapping than task-to-hand mapping increases participants’ switching behavior (Exp. 1 and Exp. 2), but not when they were instructed to randomly select tasks (Exp. 3). Thus, task-specific stimulus-response associations can change the way people mentally represent tasks and influence switching behavior, suggesting that motor effectors should be considered as a component of task representations in biasing cognitive flexibility.

“…Along these lines, EF in adults with Prader–Willi syndrome is examined by Chevalère et al (2022), in this special issue, with a particular focus on the connection between cognitive flexibility and emotion processing. Individuals with Prader–Willi syndrome are at elevated risk for emotional lability and difficulties with emotion identification.…”
Section: Executive Function In People With Intellectual Disabilitymentioning
This editorial presents an introduction to and an overview of the current JIDR special issue on "Executive Function in Intellectual Disability." The articles included in this special issue provide a contemporary, in depth exploration of questions regarding the nature of EF in individuals with ID. Topics include the emergence of EF during early childhood in ID-related conditions, the influence of EF on other domains of development, and the relationship between EF and adaptation throughout the lifespan. This editorial synthesizes the findings presented in this special issue and identifies methodological challenges that researchers will continue to face in future investigations of this important area.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
