The Sustained Attention to Response Task (SART) has been widely used in psychological literature as a measure of vigilance (the ability to sustain attention over a prolonged period of time). This task uses a Go/No-Go paradigm and requires the participants to repetitively respond to the stimuli as quickly and as accurately as possible. Previous literature indicates that performance in SART is subjected to a "speed-accuracy trade-off" (SATO) resulting from strategy choices and from the failures of controlling motor reflexes. In this study, 36 participants (n = 36) performed a series of four SARTs. The results support the perspective of strategy choice in SART and suggest that within-subjects SATO in SART should also be acknowledged in attempting to explain SART performance. The implications of the speed-accuracy trade-off should be fully understood when the SART is being used as a measure or tool.
Providing objective visual feedback on performance during resistance exercise has been shown to acutely improve performance as well as enhance self-reported levels of motivation and competitiveness. The majority of research has only tested this over single sets of exercise with male-only cohorts which, however, potentially limits the real-world applicability. The current study used an all-female cohort of eleven netball players and tested the effects of presenting objective visual feedback to participants during three consecutive sets of jump squat exercises. Compared to when no feedback was provided, participants performed significantly better when given feedback (achieving greater peak concentric movement velocities; ms-1) and reported significantly greater state motivation and task competitiveness. The findings suggest that the beneficial effects of feedback persist longer than a single set of resistance exercise and also occur in female athletes.
The Youmans Cognitive Flexibility Assessment (YCFA) was created as an easy-to-administer and entertaining assessment of cognitive flexibility. Although a validation and reliability study of the YCFA was conducted, practice effects were not assessed. This present study aims to uncover whether practice effects occur for the YCFA. Thirty-six undergraduate university students completed four rounds of the YCFA (six trials per round). Practice effects occurred in the first and second rounds, but task performance stabilized after the third round. Implications are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
