The Guilty Knowledge Test (GKT; Lykken, 1959) assesses whether suspects conceal information about a crime ( “guilty knowledge”). Previous studies have demonstrated larger physiological reactions to guilty knowledge compared to unknown information. In three experiments, we investigated whether guilty knowledge also demands attention. During an alleged polygraph examination, participants were presented with to‐be‐detected pictures ( “guilty knowledge”), nonsignificant, familiar pictures ( “mere knowledge”), and previously unseen pictures ( “neutral information”) for 250 ms in a modified dot probe task. In all three experiments, probe responses were slower on guilty knowledge trials as compared to the neutral trials. Results are discussed in terms of an information‐processing view on orienting to guilty knowledge. 相似文献

In the present study, we explored whether individual differences in inhibition, sustained attention, and working memory capacity (WMC) are related to false memory task performance. We defined the processes in such a task according to the fuzzy trace theory and used multinomial modelling methodology to measure the contribution of these latent processes. We found higher verbatim memory in participants with a high WMC, as measured by the Rotation Span task, and in individuals who committed more errors in the Sustained Attention Response Task (SART). Participants with a high WMC and low-error level in SART showed higher gist memory for targets, and individuals high in WMC also rejected orthographically related distractors more effectively due to the recollection of distractors’ corresponding targets. We also observed that participants with better inhibition control were more conservative in guessing that an item was old. 相似文献

ABSTRACTIn the process of searching for targets, our visual system not only prioritizes target-relevant features, but can also suppress nontarget-related features. Although this template for rejection has been well demonstrated, whether the features (i.e. the objects) or locations are suppressed remains unresolved due to the experimental paradigms in previous studies: in particular, object-based templates for rejection were confounded with location-based inhibition in visual search paradigms. The present study examined an object-based template for rejection by introducing search arrays comprised of two overlapping shapes with search items distributed along the shape's contours. To discourage location-based inhibition, the two shapes were spatially intermingled (Experiment 1), rotated (Experiment 2), or jiggled (Experiment 3). Participants identified the colour of a target cross. The pre-cue indicated the shape in which the target would appear (positive cue condition), the shape in which only distractors would appear (negative cue condition), or the shape that was irrelevant to the current search array (neutral cue condition). In all three experiments, the reaction times for the negative cue condition were shorter than those for the neutral cue condition, which is a hallmark of the object-based template for rejection effect, even under conditions in which location-based inhibition was discouraged. 相似文献

ABSTRACT Affect-as-information models, resource allocation models, and arousal biased competition theory predict different effects of mood on cognition. To test these theories, this study examines the effect of sad mood on response inhibition (RI) and whether emotion dysregulation impacts this potential relationship. Participants were 273 undergraduates who wrote about either a typical day or a sad event from their life. They self-reported mood and emotion regulation difficulties, and RI was a composite score of Colour-Word Stroop, Stop-Signal, and go/no-go computerised tasks. The intensity of self-reported sad mood did not affect RI as predicted, but those who wrote about sad events had worse RI. Worse emotion regulation also predicted worse RI. Cognitive loads, rumination, and mind-wandering are discussed as possible mechanisms. Findings are extended from well-established areas such as working memory to the less-established area of RI. 相似文献

Preverbal infants spontaneously represent the number of objects in collections. Is this ‘sense of number’ (also referred to as Approximate Number System, ANS) part of the cognitive foundations of mathematical skills? Multiple studies reported a correlation between the ANS and mathematical achievement in children. However, some have suggested that such correlation might be mediated by general-purpose inhibitory skills. We addressed the question using a longitudinal approach: we tested the ANS of 60 12 months old infants and, when they were 4 years old (final N = 40), their symbolic math achievement as well as general intelligence and inhibitory skills. Results showed that the ANS at 12 months is a specific predictor of later maths skills independent from general intelligence or inhibitory skills. The correlation between ANS and maths persists when both abilities are measured at four years. These results confirm that the ANS has an early, specific and longstanding relation with mathematical abilities in childhood.
Research Highlights
- In the literature there is a lively debate about the correlation between the ANS and maths skills.
- We longitudinally tested a sample of 60 preverbal infants at 12 months and rested them at 4 years (final sample of 40 infants).
- The ANS tested at 12 months predicted later symbolic mathematical skills at 4 years, even when controlling for inhibition, general intelligence and perceptual skills.
- The ANS tested at 4 years remained linked with symbolic maths skills, confirming this early and longstanding relation in childhood.

AbstractChanging automatized movement patterns often leads to initial performance decrements caused by proactive interference. In this study, we scrutinized whether proactive interference could be reduced by inhibiting the to-be-changed movement pattern by means of a physical movement constraint and verbal inhibition instructions, and whether any of the two interventions may be superior. Skilled typists typed short texts as fast and accurately as possible on a regular QWERTZ keyboard. After baseline measures, a new rule prohibiting the use of the left index finger was introduced. Subsequently, participants took part in either a verbal instruction or an additional motor restriction intervention phase. Results revealed that the original rule change was successful in inducing proactive interference in skilled typists. Most importantly, the two interventions similarly reduced proactive interference both immediately following the rule change and after ten practice sessions. We conclude that reducing proactive interference by means of physical motor restrictions and verbal instructions may be equally effective. 相似文献
