Object drawing can be supported by a number of cognitive resources, each making available visual information about the object being drawn. These resources include perceptual input, short-term visual memory, and long-term visual memory. Each of these resources has the potential to make available distinct forms of visual representation, including viewpoint-specific and viewpoint-independent representations, object-specific and category representations, and separate representations of object colour. We review neuropsychological and developmental evidence supporting these claims, including evidence that the same drawing can reflect the influence of multiple forms of visual representation. Seven experiments are then reported, investigating object drawing by 4- to 6-year-old children, to confirm the support for drawing provided by different forms of visual representation. Young children are selected for investigation because their drawing is relatively unconstrained by culturally determined norms which, in our culture, dictate that objects should be drawn just as they appear from the vantage point of the drawer. To distinguish the support provided by object and category representations, the experiments exploit the privileged links between count nouns as object labels, and representations of object categories. In addition, pre-established representations, visual or otherwise, are precluded from influencing drawing by asking the children to draw novel objects, and by creating novel count nouns with which to label the objects. The results reveal how viewpoint-specific perceptual representations, object-specific representations of shape and of colour, and category representations of shape can each impact on object drawing, and in some circumstances on the same drawing. It appears that simple drawing tasks have the potential to reveal some of the distinct types of representation able to support visual cognition. 相似文献

Using canonical analysis, a common factor in the MMPI scales of husbands and wives was found. The Sc, Pd, and Hs scales for both the husbands and the wives contributed heavily to the relationship. Other scales contributing to the correlation between the personality components of the pairs were F, Hy Pt, and Si for the husbands and Pa for the wives. The results were interpreted as indicating areas of homogeneity and heterogeneity in the personalities of married couples. 相似文献

Rare or low probability targets are detected more slowly and/ or less accurately than higher probability counterparts. Various proposals have implicated perceptual and response-based processes in this deficit. Recent evidence, however, suggests that it is attentional in nature, with low probability targets requiring more attentional resources than high probability ones to detect. This difference in attentional requirements, in turn, suggests the possibility that low and high probability targets may have different susceptibilities to attention capture, which is also known to be resource-dependent. Supporting this hypothesis, we found that, once attentional resources have begun to be engaged by detection processes, low, but not high, probability targets have a reduced susceptibility to capture. Our findings speak to several issues. First, they indicate that the likelihood of attention capture occurring when a given task-relevant stimulus is being processed is dependent, to some extent, on how said stimulus is represented within mental task sets. Second, they provide added support for the idea that the behavioural deficit associated with low probability targets is attention-based. Finally, the current data point to reduced top-down biasing of target templates as a likely mechanism underlying the attentional locus of the deficit in question. 相似文献

The relationship between cognitive and sensory processes in the brain contributes to the regulation of affective responses (pleasure–displeasure). Exercise can be used to manipulate sensory processes (by increasing physiological demand) in order to examine the role of dispositional traits that may influence an individual’s ability to cognitively regulate these responses. With the use of near infrared spectroscopy, in this study we examined the influence of self-reported tolerance upon prefrontal cortex (PFC) hemodynamics and affective responses. The hemodynamic response was measured in individuals with high or low tolerance during an incremental exercise test. Sensory manipulation was standardized against metabolic processes (ventilatory threshold [VT] and respiratory compensation point [RCP]), and affective responses were recorded. The results showed that the high-tolerance group displayed a larger hemodynamic response within the right PFC above VT (which increased above RCP). The low-tolerance group showed a larger hemodynamic response within the left PFC above VT. The high-tolerance group reported a more positive/less negative affective response above VT. These findings provide direct neurophysiological evidence of differential hemodynamic responses within the PFC that are associated with tolerance in the presence of increased physiological demands. This study supports the role of dispositional traits and previous theorizing into the underlying mechanisms (cognitive vs. sensory processes) of affective responses. 相似文献

The use of the Programme for International Student Assessment (PISA) across nations, cultures, and languages has been criticized. The key criticisms point to the linguistic and cultural biases potentially underlying the design of reading comprehension tests, raising doubts about the legitimacy of comparisons across economies. Our research focused on the type and magnitude of invariance or non-invariance in the PISA Reading Comprehension test by language, culture, and economic development relative to performance of the Australian English-speaking reference group used to develop the tests. Multi-Group Confirmatory Factor Analysis based on means and covariance structure (MACS) modeling was used to establish a dMACS effect size index for each economy for the degree of non-invariance. Only three wealthy, English-speaking countries had scalar invariance with Australia. Moderate or large effects were observed in just 31% of the comparisons. PISA index of economic, social and cultural status had a moderate inverse correlation with dMACS suggesting that socioeconomic resourcing of education played a significant role in measurement invariance, while educational practice and language factors seemed to play a further small role in non-invariance. Alternative approaches to reporting PISA results consistent with non-invariance are suggested. 相似文献

Police may engage in deceptive and coercive interrogations to obtain confessions. When a confession is later retracted, judges and juries must assess the totality of the circumstances surrounding the confession, including the interrogation techniques used and the effects of these tactics on the particular defendant. A suspect who is vulnerable and confused or who is given false evidence by a coercive interrogator may produce a false confession. Expert testimony may be necessary to help jurors understand the circumstances that lead to nonvoluntary confessions. © 1998 John Wiley & Sons, Ltd. 相似文献

研究分为问卷调查与实验研究两部分。首先,40名女性和33名男性完成有关自感配偶价值评价(SPMV)和择偶偏爱策略的问卷调查,问卷调查结果是实验研究中数据分析的基线。其次,第二部分实验开始后,被试会得到实验者编造的他人潜在择偶对象的积极正面评价,其目的在于提高被试的SPMV。可以假设,男性的SPMV与随意性行为的认同或追求有正相关,男性SPMV的提高将会更加偏爱短期的性策略;女性SPMV与随意性行为不存在相关,女性SPMV的提高不会改变女性的性策略。研究结果显示,SPMV高基线水平的男性更加认可随意性行为,男性SPMV的提高与短期策略选择的增加有关。另外,SPMV提高,而不是一般自尊的提高,与择偶策略的改变具有相关。本研究结果没有证实,与长期稳定的性关系相比,SPMV的基线水平或是提高与女性对随意性行为的认同或追求之间存在相关 相似文献

Summary: The Sixteen Personality Factors Questionnaire (16PF) was administered to 69 subjects. Each subject was asked to rate himself on the 16 personality factors on the 16PF. The 16PF scores and the self-ratings were compared by canonical analysis. Three significant relationships were identified. The relationships primarily involved indices of social interaction from the 16PF and indices of internal traits from the self-ratings. 相似文献
