Inhibition of return (IOR) refers to a processing disadvantage at a recently attended location. It is generally agreed that
when elicited in a cue-target task, IOR will not be apparent until attention is disengaged from the originally cued location
and returned to a neutral state. Here we test the hypothesis that when such disengagement is dependent on endogenous control,
a secondary task that taxes working memory capacity should delay the appearance of IOR. Participants were given a six-item
verbal working memory load prior to the peripheral cue in a cue-target detection task. Consistent with the hypothesis, the
appearance of IOR was delayed on trials for which participants had to hold information in working memory. Converging evidence
was derived from a second experiment in which the time course of IOR’s appearance, when we added a central cue to exogenously
remove attention from the peripheral cue, was unaffected by the memory load. 相似文献

Our reduced ability to correctly report two sequentially presented targets is seen in the robust effect known as the attentional
blink (AB; Raymond, Shapiro, & Arnell, 1992). One recent report (Olivers & Nieuwenhuis, 2005) strikingly reveals the AB to
be virtually abolished when non-task-demanding music occurs in the background. The authors suggest that a diffuse attentional
state is the mediating factor. Here, we seek to broaden the finding’s generality by determining if task-irrelevant visual
motion and flicker also attenuate the AB. In our experiments, the AB task was presented together with a background field of
moving dots that could moveaway from ortoward the central AB task, or flicker. In the control condition, the dots remained static. The AB was attenuated—though to different
degrees—in all experimental conditions, but not in the static condition. Our findings add to the generality of the previous
conclusions, and we emphasize an account based on the overallocation of attention. 相似文献

Permutation procedures to compute exact and resampling probability values associated with measures of association for ordered r x c contingency tables are described. Comparisons with asymptotic probability values demonstrated that exact and resampling permutation procedures were preferred for sparse contingency tables. 相似文献

Goodman and Kruskal's tau measure of categorical association is advanced as a replacement for conventional measures of effect size for r x c contingency tables. Goodman and Kruskal's tau is an asymmetric measure of categorical association which is based entirely on the observed data and possesses a clear interpretation in terms of proportional reduction in error. Comparisons with conventional measures of effect size based on chi-squared such as Pearson's phi2, Tschuprow's T2, and Cramer's V2 demonstrate the advantages of employing tau as a measure of effect size. 相似文献

Fitts's law holds that movement time (MT) increases with longer distances. Here we report a violation of this law: When the target appears in a structured, linear display with placeholders indicating the possible target locations, MT to the most distant target is not longer than MT to the second most distant target, but rather tends to be shorter. Furthermore, the presence of placeholders attenuates the range effect that occurs in the absence of placeholders. These findings suggest that Fitts's law may be limited to egocentric visuomotor action, and that the visual control of hand movements may use allocentric, in addition to egocentric, spatial information. 相似文献
