Conflict monitoring theory (CMT; Botvinick, Braver, Barch, Carter, & Cohen Psychological Review, 108, 624–652, 2001) states that response conflict, the simultaneous activation of two competing responses, increases task focus and reduces interference from irrelevant information. CMT also defines errors as conflict, and reduced interference effects have consistently been reported following errors (Ridderinkhof Psychological Research, 66, 312–323, 2002). However, previous computations of this posterror reduction of interference (PERI) have overlooked the congruency of the previous trial. This is problematic, because most errors are made on incongruent trials, creating a confound between (previous) accuracy and (previous) congruency. Therefore, it is likely that reduced interference following errors is in fact the congruency sequence effect (i.e., reduced interference following incongruent, relative to congruent, trials). Our results corroborate this idea by demonstrating that participants indeed showed significant PERI following a congruent trial, but inverse PERI following an incongruent trial. These findings are discussed in light of the adaptation-by-binding account (Verguts & Notebaert Psychological Review, 115, 518–525, 2008, Trends in Cognitive Sciences, 13, 252–257, 2009). 相似文献

Feeling we’re biased: Autonomic arousal and reasoning conflict 总被引:1,自引:0,他引:1

Human reasoning is often biased by intuitive beliefs. A key question is whether the bias results from a failure to detect
that the intuitions conflict with logical considerations or from a failure to discard these tempting intuitions. The present
study addressed this unresolved debate by focusing on conflict-related autonomic nervous system modulation during biased reasoning.
Participants’ skin conductance responses (SCRs) were monitored while they solved classic syllogisms in which a cued intuitive
response could be inconsistent or consistent with the logical correct response. Results indicated that all reasoners showed
increased SCRs when solving the inconsistent conflict problems. Experiment 2 validated that this autonomic arousal boost was
absent when people were not engaged in an active reasoning task. The presence of a clear autonomic conflict response during
reasoning lends credence to the idea that reasoners have a “gut” feeling that signals that their intuitive response is not
logically warranted. Supplemental materials for this article may be downloaded from http://cabn.psychonomic-journals.org/content/supplemental. 相似文献

This study builds on two lines of research that have so far developed largely separately: the use of additive methods to solve proportional word problems and the use of proportional methods to solve additive word problems. We investigated the development with age of both kinds of erroneous solution methods. We gave a test containing missing-value problems to 325 third, fourth, fifth, and sixth graders. Half of the problems had an additive structure and half had a proportional structure. Moreover, in half of the problems the internal and external ratios between the given numbers were integer, while in the other cases numbers were chosen so that these ratios were noninteger. The results indicate a development from applying additive methods “anywhere” in the early years of primary school to applying proportional methods “anywhere” in the later years. Between these two stages many students went through an intermediate stage where they simultaneously applied additive methods to proportional problems and proportional methods to additive problems, switching between them based on the numbers given in the problem. 相似文献

This article describes how children build increasingly abstract knowledge of linear measurement, emphasizing ways they relate space and number. Assessments indicate children struggle to understand measurement, especially concepts related to complex paths as in perimeter tasks. This article draws on developmental accounts of children's knowledge of measurement to describe the coordination of cognitive processes as a progression through increasingly abstract layers of strategy (Clements, 2003; Lehrer, 2003) within a constructivist perspective (Steffe &; Cobb, 1988; Steffe &; Thompson, 2000). This article reports 4 case studies from a 6-month teaching experiment with Grade 4 students to examine ways of promoting their strategy development. Attending to children's understanding of length along straight objects alone proved inadequate in predicting and validating models of children's developing strategies and concepts for perimeter. Setting perimeter tasks that emphasized integral relations among unit of length, sides of polygons and perimeter, and prompting children to integrate partitive, iterative, and counting schemes appeared to promote increasingly abstract length measurement strategies. The researchers came to distinguish between a naïve use of units to find length (Level 2a) and a more abstract strategy for unitizing and iterating (Level 2b), extending an earlier framework (Clements, Battista, Sarama, Swaminathan, &; McMillen, 1997). Finally, implications for instruction are drawn from the development of tasks and questioning sequences. 相似文献

Is visual awareness graded or binary? Experimental work has provided support for both possibilities, leading to two coexisting but contradictory theoretical accounts. Here we propose a promising candidate factor through which to integrate both accounts: the depth of stimulus processing required by the task. We compared color identification (a low-level task) with numerical judgements (a high-level task) performed on the very same colored number stimuli. Psychophysical curves were analyzed for both objective discrimination performance and subjective visibility ratings on a trial-by trial basis. We observed a graded relationship between stimulus duration and visibility in the low-level task, but a more non-linear relationship in the high-level task. Both patterns of results have previously been consistently associated with the graded and the dichotomous account, respectively. Follow-up experiments that manipulate the level of processing can further unify previously inconsistent results, thus integrating two major theories of visual awareness. 相似文献

This study investigated the importance of 2 resilience resources for service members’ ability to deal with threat during deployment. Military self-efficacy and family support were measured before deployment and related to work engagement and burnout levels of service members during deployment. We hypothesized that in high threat situations, low self-efficacy would lead to unfavorable outcomes, whereas in low threat situations, high self-efficacy could have negative consequences. In addition, we hypothesized that family support would compensate for both effects. The results showed these expected 3-way interactions. We found that strong self-efficacy helped service members deal with exposure to threatening situations during deployment, leading to more work engagement and less burnout. However, having strong self-efficacy without being exposed to threat during deployment reduced service members’ work engagement and increased burnout. In addition, we found that the presence of family support compensated for these effects. Service members with low self-efficacy benefitted from family support when threat exposure was high, whereas service members with high self-efficacy benefitted from family support when threat exposure was low. As such, family support seemed to act as a compensatory mechanism for the potential negative effects of self-efficacy. This underlines the importance of studying the interplay between resources that help service members deal with deployment experiences. Practical implications relate to supporting service members’ resilience through enhancing multiple resources. 相似文献

We examined the potential moderating role of Block's personality types (i.e., overcontrollers, undercontrollers, and resilients) on the longitudinal associations between adolescents’ and their best friends’ delinquency. Across three annual waves, 497 Dutch adolescents (283 boys, MAge = 13 years at Wave 1) and their best friends reported on their delinquent behaviors. Adolescents’ three personality types were obtained by latent class growth analysis on their annual reports on Big Five personality. A three‐group cross‐lagged panel analysis was performed on three waves of data. Delinquency of overcontrollers was predicted by their best friends’ delinquency, whereas delinquency of undercontrollers and resilients was not. Delinquency of undercontrollers and resilients predicted their best friends’ delinquency, but overcontrollers’ delinquency did not. These findings suggest that personality may play an important role in adolescents’ susceptibility to the influence of friends’ delinquency, as well as in youths’ ability to influence friends through their own delinquency. 相似文献

This study discusses the impact of stress specific to being lesbian, gay, or bisexual (LGB)—measured by means of the concepts of stigma consciousness and internalized homonegativity—on the mental well-being of LGB youth. Also, the effects of positive and negative social support were considered within the model. The sample consisted of 743 LGBs less than 26 years old who were recruited during the online ZZZIP survey in Flanders, Belgium. Hierarchical regression shows that LGB-specific unsupportive social interactions have the greatest direct effect on mental well-being of LGB youth, followed respectively by stigma consciousness, internalized homonegativity, and confidant support. 相似文献

ABSTRACT The current study focuses on the emergence of friendship networks among just‐acquainted individuals, investigating the effects of Big Five personality traits on friendship selection processes. Sociometric nominations and self‐ratings on personality traits were gathered from 205 late adolescents (mean age=19 years) at 5 time points during the first year of university. SIENA, a novel multilevel statistical procedure for social network analysis, was used to examine effects of Big Five traits on friendship selection. Results indicated that friendship networks between just‐acquainted individuals became increasingly more cohesive within the first 3 months and then stabilized. Whereas individuals high on Extraversion tended to select more friends than those low on this trait, individuals high on Agreeableness tended to be selected more as friends. In addition, individuals tended to select friends with similar levels of Agreeableness, Extraversion, and Openness. 相似文献
