A cornerstone of the task switching literature is the finding that task performance is typically slower and more error-prone when the task switches than when it repeats. So far, deception research has largely ignored that such cognitive switch costs should also emerge when switching between truth telling and lying, and may affect the cognitive cost of lying as reflected in higher prefrontal brain activity and slower and less accurate responding compared to truth telling. To get a grasp on the relative size of the switch costs associated with lying and truth telling, the current study had participants perform a reaction time-based deception task, in which they alternated between lying and telling the truth to yes/no questions that were related to activities performed in the lab (Experiment 1) or neutral autobiographical facts (Experiment 2). In both experiments, the error and reaction time switch costs were found to be equally large for switching from truth telling to lying and from lying to truth telling. This symmetry in switch costs can be explained from the hypothesis that lying requires a first step of truth telling, and demonstrates that task switching does not contribute to the cognitive cost of lying when the repetition/switch ratio is balanced. Theoretical and methodological implications are considered. 相似文献

Previous behavioral studies have shown that instructions about stimulus–response (S-R) mappings can influence task performance even when these instructions are irrelevant for the current task. In the present study, we tested whether automatic effects of S–R instructions occur because the instructed stimuli automatically activate their corresponding responses. We registered the lateralized readiness potentials (LRPs) that were evoked by the instructed stimuli while participants were performing a task for which those mappings were irrelevant. Instructed S–R mappings clearly affected task performance in electrophysiological and behavioral measures. The LRP was found to deflect in the direction of the response tendency that corresponded with the instructed S–R mapping. Early activation of the instructed response was observed but occurred predominantly on slow trials. In contrast, response conflict evoked by instructed S–R mappings did not modulate the N2 amplitude. The results strongly suggest that, like experienced S–R mappings, instructed S–R mappings can lead to automatic response activation, but possibly via a different route. 相似文献

An examination of how members of military marriages were affected by and adapted to OIF/OEF deployment found three themes:
communicating to stay connected, emotional and marital intimacy, and managing change. The findings demonstrate the nuanced
and subtle nature of deployment-related challenges. While open and frequent communication was important in the adaptation
process, communication was not synonymous with transparency. Unshared stories created a void that prevented couples from confiding
in and supporting their partners. Although wives maintained their marriages by restraining sexual desires and over-extending
their responsibilities post-deployment, these behaviors had a negative effect on marital quality. Clinical and research implications
are discussed. 相似文献
