ADHD Dimensions and Sluggish Cognitive Tempo Symptoms in Relation to Self-Report and Laboratory Measures of Neuropsychological Functioning in College Students.

Objective: This study examined ADHD and sluggish cognitive tempo (SCT) symptoms in relation to self-report and laboratory measures of neuropsychological functioning in college students.

Method: College students ( N = 298, aged 17-25, 72% female) completed self-reports of ADHD, SCT, depression, sleep, functional impairment, and executive functioning (EF). Participants also completed a visual working memory task, a Stroop test, and the Conners' Continuous Performance Test-II (CPT-II).

Why don't guiding cues always guide in behavior chains?

This research focused on the changes in stimulus control that influence an animal's ability to master a behavioral skill. We assessed stimulus control by (a) predictive environmental cues (panel lights) and (b) practice cues resulting from the subject's own behavior, as rats learned to complete a left-right lever-press sequence. Following a demonstration of overshadowing by Reid, Nill, and Getz (Behavioural Processes 84: 511-515, 2010), in which stimulus control by the panel lights overshadowed control by practice cues, four additional experiments replicated and assessed this overshadowing effect.
