Visual-Attentional Span and Lexical ­Decision in Skilled Adult Readers
Peer reviewed Peer reviewed
Direct linkDirect link
Holmes, Virginia M.; Dawson, Georgia – Journal of Research in Reading, 2014
The goal of the study was to examine the association between visual-attentional span and lexical decision in skilled adult readers. In the span tasks, an array of letters was presented briefly and recognition or production of a single cued letter (partial span) or production of all letters (whole span) was required. Independently of letter…

Working Memory Training for Adolescents with Cannabis Use Disorders: A Randomized Controlled Trial
Peer reviewed Peer reviewed
Direct linkDirect link
Sweeney, Mary M.; Rass, Olga; DiClemente, Cara; Schacht, Rebecca L.; Vo, Hoa T.; Fishman, Marc J.; Leoutsakos, Jeannie-Marie S.; Mintzer, Miriam Z.; Johnson, Matthew W. – Journal of Child & Adolescent Substance Abuse, 2018
Adolescent cannabis use is associated with working memory impairment. The present randomized controlled trial assigned adolescents ages 14 to 21 enrolled in cannabis use treatment to receive either working memory training (experimental group) or a control training (control group) as an adjunctive treatment. Cognitive function, drug use, and other…

The Use of Visual Orientation Feedback to Facilitate Attention and Task Performance.
Peer reviewed Peer reviewed
Jackson, Gary M. – Mental Retardation, 1979
Task specific attending behavior of a mentally retarded adult engaged in a chain-cutting task was substantially increased by using a differential reinforcement procedure with a feedback stimulus for appropriate visual orientation. (Author/DLS)

Effects of Background Event Rate on Sustained Attention of Mentally Retarded and Nonretarded Adults.
Tomporowski, Phillip D.; And Others – American Journal on Mental Retardation, 1990
Mentally retarded and nonretarded adults (n=32) performed visual vigilance tests in which single digits were presented at either a fast or slow rate and the rate shifted without warning. Retarded observers detected fewer targets and made more false alarms than did nonretarded observers in all test conditions. (Author/JDD)

The Effects of a Shift in Background Event Rate on the Vigilance Performance of the Mentally Retarded.
Hayden, Alys M.; Tomporowski, Phillip D. – 1988
This research study evaluated the effects of memory demand on sustained attention, by varying the time interval between the presentations of stimuli in a cognitive vigilance task. Sixteen retarded and 16 nonretarded adult observers performed four 60-minute visual vigilance tasks in which single digits were presented sequentially and successively…

Developmental Trends in Distractibility: Is Absolute or Proportional Decrement the Appropriate Measure of Interference?
Peer reviewed Peer reviewed
Well, Arnold D.; And Others – Journal of Experimental Child Psychology, 1980
Robust interference effects were found which declined with age. Manipulating discriminability of the relevant stimulus dimension resulted in large changes in sorting time, but interference effects did not vary with baseline difficulty. These results were interpreted as strongly supporting both an absolute decrement model and a developmental trend…

Abnormal Attention in Autism Shown by Steady-State Visual Evoked Potentials.
Peer reviewed Peer reviewed
Belmonte, Matthew – Autism: The International Journal of Research and Practice, 2000
Eight males with autism were required to shift attention between rapidly flashed targets alternating between left and right visual hemifields. When targets were separated by less than 700 ms, steady-state brain electrical response in both hemispheres was augmented and background EEG decreased for rightward shifts as compared with leftward shifts.…
