Eichorn, Naomi; Pirutinsky, Steven – Journal of Speech, Language, and Hearing Research, 2021
Purpose: This study compared attention control and flexibility in school-age children who stutter (CWS) and children who do not stutter (CWNS) based on their performance on a behavioral task and parent report. We used a classic attention-shifting paradigm that included manipulations of task goals and timing to test effects of varying demands for…

Green, Jessica J.; Woldorff, Marty G. – Cognition, 2012
The observation of cueing effects (faster responses for cued than uncued targets) rapidly following centrally-presented arrows has led to the suggestion that arrows trigger rapid automatic shifts of spatial attention. However, these effects have primarily been observed during easy target-detection tasks when both cue and target remain on the…

Byrd, Keena S.; Caldwell, Barrett S. – Behaviour & Information Technology, 2011
The primary objective of this research was to compare procedure-based task performance using three common mobile screen sizes: ultra mobile personal computer (7 in./17.8 cm), personal data assistant (3.5 in./8.9 cm), and SmartPhone (2.8 in./7.1 cm). Subjects used these three screen sizes to view and execute a computer maintenance procedure.…

Lustig, Cindy; Meck, Warren H. – Brain and Cognition, 2011
The perception of time is heavily influenced by attention and memory, both of which change over the lifespan. In the current study, children (8 yrs), young adults (18-25 yrs), and older adults (60-75 yrs) were tested on a duration bisection procedure using 3 and 6-s auditory and visual signals as anchor durations. During test, participants were…

Lum, Jarrad A. G.; Conti-Ramsden, Gina; Lindell, Annukka K. – Brain and Cognition, 2007
Rapid processing deficits have been the subject of much debate in the literature on specific language impairment (SLI). Hari and Renvall (2001) [Hari, R. & Renvall, H. (2001). Impaired processing of rapid stimulus sequences in dyslexia. "Trends in cognitive sciences", 5, 525-532.] proposed that the source of this deficit can be attributed to…

Cagigas, Xavier E.; Vincent Filoteo, J.; Stricker, John L.; Rilling, Laurie M.; Friedrich, Frances J. – Brain and Cognition, 2007
Parkinson's disease (PD) patients and healthy controls were administered a flanker task that consisted of the presentation of colored targets and distractors. Participants were required to attend to the center target and identify its color. The stimulus displays were either congruent (i.e., the target and flankers were the same color) or…
