A study was conducted to examine Spanish police officers' and nonofficers' lie‐ and truth‐detection accuracy, as well as their estimated detection ability. The participants were 121 police officers and 146 undergraduates who watched videotaped truthful and deceptive statements. They had to indicate: (1) whether each statement was truthful or deceptive, and (2) how good police officers were, in comparison with the general population, at detecting the truthfulness or deceptiveness of a statement. Results indicate that police officers' accuracy was not higher than that of nonofficers, rather, while the officers reached an accuracy rate close to chance probability, the undergraduates surpassed that probability. Officers had a very strong tendency to judge the statements as deceptive; this made them less accurate than the students in judging the truthful accounts, while both groups reached a similar accuracy when judging the deceptive ones. Both occupational samples considered that the police are more capable of identifying truths and lies than the general population. However, this belief was stronger among the officers themselves than among the nonofficers. No significant correlation between estimated ability and accuracy was found for either sample. The results are explained in terms of the participants' wrong beliefs about the cues to deceit and the socialization process that police officers undergo, which would increase their confidence and perceived ability while hindering their learning of the actual indicators of deceit. The need for officers to receive training is emphasized, and some directions are given on how this training should be carried out. 相似文献

Reliability (internal consistency and test‐retest) and validity (construct and factorial) of the Orthogonal Cultural Identification Scale (OCIS; E. R. Oetting & F. Beauvais, 1990–1991) were evaluated in a sample of Asian American university students. Ethnic identification, measured using the OCIS, and acculturation, measured using the Suinn‐Lew Asian Self‐Identity Acculturation Scale (R. M. Suinn, K. Rickard‐Fugueroa, S. Lew, & P. Vigil, 1987), are hypothesized to measure related but separate constructs. Análisis de fiabilidad (consistencia interna y estabilidad temporal), y de validez (conceptual y factorial) de la Escala Ortagonal de Identificación Cultural (OCIS; E. R. Oetting & F. Beauvais, 1990–1991) fueron evaluados en un grupo de estudiantes universitarios Asiáticos Americanos. La identificación étnica fue medida usando la OCIS, y la aculturación fue medida usando la Escala de Identidad de Ser y Aculturación Asiática de Suinn‐Lew (R. M. Suinn, K. Rickard‐Figueroa, S. Lew, & P. Vigil, 1987). Se presenta la hipótesis que la identificación étnica y la aculturación miden conceptos separados que estan relacionados. 相似文献

This study tested if children with specific language impairment (SLI) or children with specific reading disability (SRD) have abnormal brain responses to sounds. We tested 6‐ to 12‐year‐old children with SLI (N =19), children with SRD (N =55), and age‐matched controls (N =36) for their passive auditory event‐related potentials (ERPs) to tones, rapid tones, vowels and consonant‐vowels. Thirty‐eight percent of the children with SLI or SRD had less typical passive auditory ERPs in the N1–P2 window to sounds in general, rather than to tones, rapid tones, vowels or consonant‐vowels specifically. The ERPs of these children were significantly ‘flatter’ in the N1–P2 region than normal. All the children with flatter ERPs in the N1–P2 region had poor non‐word reading. A subgroup of these poor non‐word readers also had poor non‐word repetition. These findings support the hypothesis that impaired auditory processing is a causal risk factor for both SLI and SRD. 相似文献

A System for Relational Reasoning in Human Prefrontal Cortex 总被引:7,自引:0,他引:7

The integration of multiple relations between mental representations is critical for higher level cognition. For both deductive- and inductive-reasoning tasks, patients with prefrontal damage exhibited a selective and catastrophic deficit in the integration of relations, whereas patients with anterior temporal lobe damage, matched for overall IQ but with intact prefrontal cortex, exhibited normal relational integration. In contrast, prefrontal patients performed more accurately than temporal patients on tests of both episodic memory and semantic knowledge. These double dissociations suggest that integration of relations is a specific source of cognitive complexity for which intact prefrontal cortex is essential. The integration of relations may be the fundamental common factor linking the diverse abilities that depend on prefrontal function, such as planning, problem solving, and fluid intelligence. 相似文献

The signing of an organ donation letter was examined among 149 unmarried university students. The letter was developed for the purpose of conveying one's wishes regarding posthumous donation to one's next of kin. Predictors of letter signing were examined that explain hypothesized inconsistencies between the behavioral intention to sign and actual letter-signing behavior. Respondents were offered the opportunity to sign and send the donation letter to their parents. As predicted, reported willingness to sign the letter was only moderately related to actual behavior. Decision confidence, organ donation knowledge, and perceived decision importance positively influenced signing, independent of willingness. Unfavorability toward defending one's donation decision to one's parents inhibited signing, even among those expressing a high initial willingness to sign. 相似文献

The effects of acquisition and maintenance of prerequisite interactions, such as attending behavior, nonverbal imitative behavior, and disruptive behavior, on the learning of nonvocal verbal behavior and vocal imitation were evaluated. Four severely retarded children were selected on the basis of low level or absence of the target behaviors (nonvocal verbal behavior and vocal imitation) and failure to reach the acquisition criterion on prerequisite behavior. The results were evaluated visually and by time series analysis. Findings indicated that the acquisition of prerequisite interactions led to superior performance and fewer trials to reach criteria in this language intervention.

Effects of subchronic administration of gammahydroxybutyrate (GHB) on spatial working memory in rats
GHB, a popularly known drug as "liquid ecstasy", is a substance with abuse potential. Among the possible described side-effects after the continued consumption of GHB are amnesia and deterioration of memory. Likewise, recent studies indicate the existence of neurotoxicity in certain brain regions after its prolonged treatment. The aim of this study was to examine the effect of the subchronic administration of GHB (10 and 100 mg/kg) on spatial memory and sensoriomotor reflexes in male rats, using the Morris water maze and a battery of sensoriomotor tests, respectively. The results indicated that animals treated with GHB (10 mg/kg) showed a greater latency of escape during the phase of acquisition in the days first and third of tests, as compared with the control group (p<0.05), as well as a deterioration of grasping reflex with the two doses of GHB (p<0.01). Numerous studies indicated that the medial prefrontal cortex is a crucial neuronal substrate in the working memory and grasping reflex modulation. These results suggest that prolonged administration of GHB could alter structure and/or function of the medial prefrontal cortex, as well as its interconnections with other brain regions involved in the evaluated cognitive and neurological processes. 相似文献

Community-based research often brings investigators from different disciplinary backgrounds together with community representatives to conduct research on topics of mutual concern. This paper describes a case example that illustrates an interdisciplinary/intersectoral study of depression and barriers to mental health care among older adults and illustrate the factors central to implementing a successful research partnership. It will address the following conditions that facilitate and challenge interdisciplinary/intersectoral research: (1) achieving commonality of purpose in study design and research and referral approaches; (2) ensuring the ability to develop, field-test and implement psychometrically rigorous and culturally and qualitatively appropriate instruments; (3) building effective management structures for interdisciplinary/intersectoral research partnerships; and (4) identifying, training and supporting qualified researchers to carry out a mental health study with older ethnically diverse adults. The paper concludes with strengths and limitations of the approach. 相似文献

In this paper we present a case of "word-meaning deafness," characterised by serious problems in the comprehension of spoken language, whilst repetition and writing words and non-words from dictation are preserved. This performance indicates the impossibility of correctly accessing phonological representation from the semantic representation of words. Neuropsychological evidence on specific alterations in word-meaning disorders is scarce, and this study contributes new findings with a Spanish-speaking patient. The nature of the processes involved in understanding language and the cerebral mechanisms that might be affected in each case were discussed, in accordance with current neuropsychological theories. 相似文献
