In the rubber hand illusion (RHI) one’s hand is hidden, and a fake hand is visible. We explored the situation in which visual information was available indirectly in a mirror. In the mirror condition, compared to the standard condition (fake hand visible directly), we found no reduction of the RHI following synchronised stimulation, as measured by crossmanual pointing and by a questionnaire. We replicated the finding with a smaller mirror that prevented visibility of the face. The RHI was eliminated when a wooden block replaced the fake hand, or when the hand belonged to another person or mannequin. We conclude that awareness of the reflection is the critical variable, despite the distant visual localisation of the hand in a mirror and the third-person perspective. Stimuli seen in a mirror activate the same response as stimuli seen in peripersonal space, through knowledge that they are near one’s body. 相似文献

Instrumental performance in rats with hippocampal lesions is insensitive to the degradation of action-outcome contingencies, but sensitive to the effects of selective devaluation by satiation. One interpretation of this dissociation is that damage to the hippocampus impairs the formation of context-outcome associations upon which the effect of contingency degradation, but not selective satiation, relies. Here, we provide a direct assessment of this interpretation, and showed that conditioned responding to contexts did not show sensitivity to selective satiation (Experiment 1), and confirmed that instrumental performance was sensitive to selective satiation (Experiment 2) following hippocampal cell loss. 相似文献

Latent variable modeling methods have demonstrated utility for understanding the structure of executive control (EC) across development. These methods are utilized to better characterize the relation between EC and mathematics achievement in the preschool period, and to understand contributing sources of individual variation. Using the sample and battery of laboratory tasks described in Wiebe, Espy and Charak (2008), latent EC was related strongly to emergent mathematics achievement in preschool, and was robust after controlling for crystallized intellectual skills. The relation between crystallized skills and emergent mathematics differed between girls and boys, although the predictive association between EC and mathematics did not. Two dimensions of the child ’s social environment contributed to mathematics achievement: social network support through its relation to EC and environmental stressors through its relation with crystallized skills. These findings underscore the need to examine the dimensions, mechanisms, and individual pathways that influence the development of early competence in basic cognitive processes that underpin early academic achievement. 相似文献

Active vision requires the integration of information coming from the retina with that generated internally within the brain, especially by saccadic eye movements. Just as visual information reaches cortex via the lateral geniculate nucleus of the thalamus, this internal information reaches the cerebral cortex through other higher-order nuclei of the thalamus. This review summarizes recent work on four of these thalamic nuclei. The first two pathways convey internal information about upcoming saccades (a corollary discharge) and probably contribute to the neuronal mechanisms that underlie stable visual perception. The second two pathways might contribute to the neuronal mechanisms underlying visual spatial attention in cortex and in the thalamus itself. 相似文献

This study aimed at extending the deception literature by examining lie‐telling strategies given by persons with criminal experience. In interviews taking place in prisons, offenders (n = 35) provided lie‐telling strategies in a free narrative style. In an inductive content analysis, we coded both all strategies provided as well as one principal strategy for each participant. In total, 13 strategies were identified, which were grouped into three broader category groups: general verbal, general nonverbal, and specific interview strategies. The most often stated strategies were Close to truth, Eye contact, and No strategy. The most often stated principal strategies were Close to truth, Not giving away information, and No strategy. Some participants provided strategies, such as not giving away information at all in interviews/interrogations, which showed a sophisticated understanding of the police interview situation and the task of the police and prosecutor. Overall, the participants showed great diversity in preferred lie‐telling strategy. The results are partly in line with previous research from student samples and provide new insights into the criminally experienced individuals' lie‐telling strategies. The results are discussed with regard to impression and information management and police interrogation practice. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

The percentage of older adults in the general population is growing. As a result, older adults are coming more frequently into contact with the Criminal Justice System as witnesses to and victims of crime. Older adults are also over‐represented in crimes where conversation detail is of particular importance to an investigation (e.g. distraction burglary). The present study therefore examined the efficacy of cognitive interview (CI) compared with structured interview in improving the recall of an event by older witnesses, specifically conversational detail. Young adults (19–54 years old), young‐old adults (60–74 years old), and old‐old adults (75+ years old) were asked to watch a short film of a laptop theft and were then, after a 1.5 hour delay, randomly allocated to one of two interview conditions. It was found that the CI significantly increased recall of all age groups, without increasing the amount of incorrect or confabulated information reported. The individuals in the young adult and the young‐old adult conditions were found to remember significantly more than the individuals from the old‐old adult condition, without decreasing the accuracy of the information. The CI enhanced memory for conversation gist, person and action detail. Results will be discussed in relation to interviewing and investigating practices.

A network consisting of left dorsolateral prefrontal cortex (LDLPFC) and dorsal anterior cingulate cortex (dACC) has been implicated in top-down attentional control. Few studies have systematically investigated how this network is altered in psychopathology, despite evidence that depression and anxiety are associated with attentional control impairments. Functional MRI and dense-array event-related brain potential (ERP) data were collected in separate sessions from 100 participants during a color-word Stroop task. Functional MRI results guided ERP source modeling to characterize the time course of activity in LDLPFC (300-440 ms) and dACC (520-680 ms). At low levels of depression, LDLPFC activity was indirectly related to Stroop interference and only via dACC activity. In contrast, at high levels of depression, dACC did not play an intervening role, and increased LDLPFC activity was directly related to decreased Stroop interference. Specific to high levels of anxious apprehension, higher dACC activity was related to more Stroop interference. Results indicate that depression and anxious apprehension modulate temporally and functionally distinct aspects of the frontocingulate network involved in top-down attention control. 相似文献

Two studies evaluated the validity of the interpersonal scales, Dominance (DOM) and Warmth (WRM), from the Personality Assessment Inventory (PAI; Morey, 1991, 2007) to measure the 2 dimensions of the interpersonal circumplex (IPC). In Study 1, 114 college freshmen completed the PAI and the Interpersonal Adjectives Scale (IAS; Wiggins, 1995). In Study 2, 170 college students completed the PAI and the Inventory of Interpersonal Problems-Short Circumplex (IIP-SC; Soldz, Budman, Demby, & Merry, 1995). The results of both studies supported the convergent validity of DOM and WRM, although discriminant validity was stronger using the IIP-SC as the criterion. Circumplex projections placed DOM and WRM in the appropriate segments of both the IAS and IIP-SC. These findings provide additional support for the validity of the PAI interpersonal scales as measures of the primary dimensions of the IPC. 相似文献

Children under 3½ years of age or so are often thought to produce the same types of scribbles for writing and drawing. We tested this idea by asking Chinese 2- to 6-year-olds to write and draw four targets. In Study 1, Chinese adults judged the status of the productions as writings or drawings. The adults performed significantly above the level expected by chance even with the productions of 2- to 2½-year-olds. In Study 2, we examined specific characteristics of the children’s writings and drawings. Although the younger children’s scribbles bore little resemblance to the correct characters, they tended to be smaller, sparser, and more angular than their artwork, with less filling in. Differences were also found in paper use and implement use. Children did not appear to distinguish writing from drawing for their own names before they did so for other targets. 相似文献
