结构限制和信息干扰对双重作业绩效的影响

研究通过改变双重任务呈现的间隔时间来探讨结构限制与信息干扰对双重任务操作绩效的影响。实验结果表明：(1)两种作业呈现的间隔时间对双重任务操作绩效有明显的影响。间隔时间越大,双重任务的作业绩效越高。(2)信息干扰对双重任务的操作有明显的影响。信息干扰越大,双重任务的操作绩效越差。(3)两个作业呈现的间隔时间不同并不影响信息干扰对双重任务操作绩效的作用。根据实验结果,该研究提出了三因素假设：结构限制、信息干扰和资源竞争是影响双重任务操作绩效的三个主要因素。     

The relationship between political participation and civic community of migrants in the Netherlands

This article examines the relationship between different forms of political participation and the civic participation in organizations of ethnic minorities in the Netherlands. We have investigated the turnout rates and voting behaviour of migrants, the participation of councillors from ethnic minority groups and party of officials in four cities and the organizations of ethnic minorities in Amsterdam and on a national level. The combination of all this information supplies us with a picture of the civic community of the ethnic groups in the Netherlands and we theorize about explanations on differences between these groups.     

文化心理学的启示意义及其发展趋势

心理学的研究对象乃是一种文化现象,是与人类文化互相创生发展的过程。心理学研究对象的独特性质决定着,心理学研究不可能脱离具体的文化背景。文化心理学的兴起适时地满足了当代心理学发展的要求。作为心理学研究的一种重要视角,文化心理学蕴涵着对心理学的研究对象、研究方法、研究目标及学科性质的独特理解。由于文化心理学兴起的时间较短,它必然还要不断吸取各种养分,实现内部取向的不断整合,提出更加明确的研究纲领。

Reinforcement sensitivity of sex offenders and non‐offenders: An experimental and psychometric study of reinforcement sensitivity theory

This study tested predictions of Gray's Reinforcement Sensitivity Theory (RST) in subgroups of sex offenders and male non‐offenders using an experimental choice task consisting of a reward and a non‐reward phase. In addition, RST‐related psychometric measures were used. Both experimental and psychometric data were of interest to determine whether sex offenders could be reliably differentiated from non‐offenders. Paraphilic (N=50) and impulse control‐disordered (N=48) sex offenders showed greater sensitivity to continuous reward than male non‐offenders (N=51). Impulse control‐disordered sex offenders showed less behavioural adaptation under non‐reward than both paraphilic sex offenders and male non‐offenders. In addition, reward sensitivity, rash‐spontaneous impulsivity, and anxiety measures discriminated sex offenders from male non‐offenders. The results suggest that reinforcement sensitivity is a promising personality trait for differentiating subgroups of sex offenders from non‐offenders. The experimental and psychometric results illustrate that predictive accuracy in forensic settings could be improved by combining several types of data.     

The relationship of maternal mentalization and executive functioning to maternal recognition of infant cues and bonding

The study examined associations between maternal mentalization ability, executive functioning, recognition of infant cues, and bonding in a non‐clinical sample of mothers. It employed a correlational design. Sixty‐four mothers of young infants completed assessments of mentalization ability, executive functioning, and bonding. Photographs of infant facial expressions were utilized to assess ability to recognize infant cues of emotion, but this was not found to correlate with either maternal mentalization or executive functioning ability. Whilst a trend towards a significant positive relationship between mothers' cued ability to attribute mental states and their ability to recognize infant facial expressions was observed, no significant relationships were found between bonding scores and performance on the executive functioning and mentalization measures. The present study contributes to our current understanding of the influence of maternal cognitive factors, specifically mentalization and executive functioning, on the development of the mother–infant relationship. Future research, methodological issues, and clinical and theoretical implications are discussed.     

Visual homing in the absence of feature-based landmark information

Despite that fact that landmarks play a prominent role in human navigation, experimental evidence on how landmarks are selected and defined by human navigators remains elusive. Indeed, the concept of a ‘landmark’ is itself not entirely clear. In everyday language, the term landmark refers to salient, distinguishable, and usually nameable objects, rendering the problem of landmark recognition a special case of the general object recognition problem. In contrast, in the insect and robot literature, this notion of landmarks is often replaced by the “local position information” [e.g., Trullier, O., Wiener, S., Berthoz, A., &; Meyer, J.-A. (1997). Biologically based artificial navigation systems: Review and prospects. Progress in Neurobiology, 51, 483–544], referring to the entire set of sensor readings obtained at one location. This set may then serve as a characteristic of the particular location. Honey bees have been shown to base place recognition and homing on a snapshot-like memory of the place’s visual environment, not on the distances to recognized objects [Cartwright, B., &; Collett, T. (1983). Landmark learning in bees. Experiments and models. Journal of Comparative Physiology A, 151, 521–543]. A number of theoretical models of snapshot-based homing [e.g., Franz, M., Schölkopf, B., Mallot, H. A., Bülthoff, H. H. (1998). Where did I take that snapshot? Scene-based homing by image matching. Biological Cybernetics, 79, 191–202; Vardy, A., &; Möller, R. (2005). Biologically plausible visual homing methods based on optical flow techniques. Connection Science, 17, 47–89] predict that the accuracy of snapshot-based homing should depend on image contrast. For rodent hippocampal place fields, models have been developed using additional image information such as three-dimensional depth and allocentric orientations (e.g., room axes) and are thus less sensitive to image contrast and noise [e.g. Barry, C., Lever, C., Hayman, R., Hartley, T., Burton, S., O’Keefe, J., et al. (2006). The boundary vector cell model of place cell firing and spatial memory. Reviews in the Neurosciences, 17, 71–79]. Here, we study human visual homing in a virtual environment void of objects and readily detected image features. The environment was a circular room with a homogenous colour gradient covering the wall and uniform floor and ceiling. Subjects were able to approach remembered places. Accuracy decreased with colour gradient modulation and room size, in qualitative agreement with the snapshot model but not with other models of place recognition. We conclude that human memory for places can make use of a snapshot algorithm.     

An inner face advantage in children's recognition of familiar peers

Children’s recognition of familiar own-age peers was investigated. Chinese children (4-, 8-, and 14-year-olds) were asked to identify their classmates from photographs showing the entire face, the internal facial features only, the external facial features only, or the eyes, nose, or mouth only. Participants from all age groups were familiar with the faces used as stimuli for 1 academic year. The results showed that children from all age groups demonstrated an advantage for recognition of the internal facial features relative to their recognition of the external facial features. Thus, previous observations of a shift in reliance from external to internal facial features can be attributed to experience with faces rather than to age-related changes in face processing.
