Such difficulties may suggest that attention control is not a measurable general cognitive ability but may instead be highly task-specific. Accuracy rates from the antisaccade task are a notable exception to the measurement difficulties often seen in other tasks, but the measure\u0026rsquo;s construct validity has been questioned. Some researchers have argued that antisaccade accuracy is a function of individual differences in general processing speed (e.g., Rey-Mermet et al., 2019). The present study evaluated this position in a combined differential-experimental study. I assessed whether the adaptive procedures adopted by previous studies in non-attention-demanding tasks increased attention control demands, leading to inaccurate estimates of criterion-related validity. I compared two versions of the prosaccade task (a non-attention-demanding variant of the antisaccade task), a non-adaptive version and an adaptive version which adjusted the presentation duration of a target stimulus on a trial-by-trial basis. I also attempted to eliminate the relationship between antisaccade accuracy and working memory capacity\/fluid intelligence by accounting for speed measures from both prosaccade tasks. Mean pupil size was larger in the pre-target period of the adaptive prosaccade task than in the non-adaptive prosaccade task, suggesting the adaptive procedure made the task more effortful. Crucially, however, no matter how I attempted to control for processing speed, I could not eliminate the relationship between antisaccade accuracy and cognitive abilities, implying that antisaccade accuracy is not merely a proxy measure for general speed.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Are prosaccades always automatic?: Validating the antisaccade task as a measure of controlled attention"}],"uid":"27707","created_gmt":"2023-01-25 17:43:36","changed_gmt":"2023-01-25 17:43:36","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2023-02-03T16:00:00-05:00","event_time_end":"2023-02-03T18:00:00-05:00","event_time_end_last":"2023-02-03T18:00:00-05:00","gmt_time_start":"2023-02-03 21:00:00","gmt_time_end":"2023-02-03 23:00:00","gmt_time_end_last":"2023-02-03 23:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"111531","name":"ms defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
