These cognitive abilities are quantitatively accounted for by Bundesen&#039;s theory of visual attention (TVA; Bundesen, 1990). Previous studies have suggested that TVA-based assessments are sensitive to inter-individual differences in spatial bias, visual short-term memory capacity, top-down control, and processing speed in healthy volunteers as well as in patients with various neurological and psychiatric conditions. However, most neuropsychological assessments of attention and executive functions, including TVA-based assessment, make use of alphanumeric stimuli and\/or are performed verbally, which can pose difficulties for individuals who have troubles processing letters or numbers. Here we examined the reliability of TVA-based assessments when stimuli are used that are not alphanumeric, but instead based on line-drawings of fruits and vegetables. We compared five TVA parameters quantifying the aforementioned cognitive abilities, obtained by modeling accuracy data on a whole\/partial report paradigm using conventional alphabet stimuli versus the food stimuli. Significant correlations were found for all TVA parameters, indicating a high parallel-form reliability. Split-half correlations assessing internal reliability, and correlations between predicted and observed data assessing goodness-of-fit were both significant. Our results provide an indication that line-drawings of fruits and vegetables can be used for a reliable assessment of attention and short-term memory.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-6964","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Department of Brain and Cognition, KU Leuven, Leuven, Belgium.","annee":"2018","mois":"0","numero":"9","page":"207","auteurs":[{"ID":6962,"post_author":"0","post_date":"2018-12-03 17:43:51","post_date_gmt":"2018-12-03 16:43:51","post_content":"","post_title":"Tianlu Wang","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"tianlu-wang","to_ping":"","pinged":"","post_modified":"2018-12-03 17:43:51","post_modified_gmt":"2018-12-03 16:43:51","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/tianlu-wang\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":6963,"post_author":"0","post_date":"2018-12-03 17:43:52","post_date_gmt":"2018-12-03 16:43:52","post_content":"","post_title":"Celine R Gillebert","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"celine-r-gillebert","to_ping":"","pinged":"","post_modified":"2018-12-03 17:43:52","post_modified_gmt":"2018-12-03 16:43:52","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/celine-r-gillebert\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":4698,"post_author":"0","post_date":"2018-12-03 17:20:00","post_date_gmt":"2018-12-03 16:20:00","post_content":"","post_title":"Frontiers in psychology","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"frontiers-in-psychology","to_ping":"","pinged":"","post_modified":"2018-12-03 17:20:00","post_modified_gmt":"2018-12-03 16:20:00","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/frontiers-in-psychology\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v23.6 (Yoast SEO v23.6) -
