先前研究表明,对于自我行为,相对于近期过去,个体对远期过去正性行为的表征更倾向于特质性和抽象性,但对负性行为的表征未获得明确的类似效应(申之美等,2010)。本研究以特质性和行动性行为描述句子为实验材料,通过两个实验考察了未来时间距离对自我正性行为和负性行为的表征特征的影响,以进一步探讨评价内容的效价特性对于建构水平的心理距离效应的调节作用。实验结果发现,相对于近期未来,被试对远期未来自我的正性行为更倾向于抽象的特质性表征,但在负性行为上未获得类似效应。个体对未来自我行为的正性期待和负性回避倾向可能是自我行为表征缺乏距离效应的心理机制。  相似文献

Although it is now well established across diverse samples that the frequency of offending ‘decays’ as distance from the home/base increases, it remains unclear what form of decay function best characterises this relationship. Different forms of decay function reflect different patterns and rates of decrease in the likelihood of offending as distance from the home/base increases. These different patterns imply rather different underlying psychological processes. Therefore, considerations of the particular function characterising distance decay elucidate explanations of offender spatial behaviour. To bring to light the possible psychological and behavioural processes inherent in offending distance decay, the present study examined the fit of logarithmic, negative exponential, and quadratic decay functions to the distribution of the distances travelled to offend by a sample of 70 prolific burglars from the UK. It is argued that these functions are consistent with the operation of perceptual processes of magnitude estimation, friction or effort effects, and the influences of cost‐benefit assessments, respectively. The results indicate that offending distance decay patterns most closely fit the logarithmic function, consistent with Stevens' perceptual processes of distortion in magnitude estimation, whilst not ruling out additional processes relating to the increased effort required in travelling greater distances to offend. Because most geographical profiling systems are built upon the distance decay function, the impact of utilising the different forms of function on the accuracy of geographic profiles was also assessed utilising ‘search cost’ calculations. The results showed little impact of applying different decay functions. Thus, whilst the decay function does have important theoretical implications for understanding offender spatial behaviour, it is noted that the particular variant used does not significantly impact on the effectiveness of geographical profiling systems as they currently exist.

Likelihood surface methods for geographic offender profiling rely on several assumptions regarding the underlying location choice mechanism of an offender. We propose an ex ante test for checking whether a given set of crime locations is compatible with two necessary assumptions: circular symmetry and distance decay. The proposed (SDD) test compares the observed inter point distances of a given series of crimes with a theoretical distribution function governed by these assumptions, using a Monte Carlo simulation procedure for approximating that distribution function. We apply the SDD test to data on serial burglary from both the UK and the Netherlands. In most cases, the assumption of an underlying symmetric distance decay function has to be rejected.

Classification problems (“find the odd-one-out”) are frequently used as tests of inductive reasoning to evaluate human or animal intelligence. This paper introduces a systematic method for building the set of all possible classification problems, followed by a simple algorithm for solving the problems of the R-ASCM, a psychometric test derived from this method. The average Hamming distance finds repetitions of features between and within the problems' sets; it manages to solve 97% of such problems. This performance is equaled only by superior human adults. Finally, these results demonstrate that a simple two-step algorithm can improve categorical case-based reasoning and k-NN algorithms while clarifying the cognitive basis of classification.  相似文献

ABSTRACT— Distance perception seems to be an incredible achievement if it is construed as being based solely on static retinal images. Information provided by such images is sparse at best. On the other hand, when the perceptual context is taken to be one in which people are acting in natural environments, the informational bases for distance perception become abundant. There are, however, surprising consequences of studying people in action. Nonvisual factors, such as people's goals and physiological states, also influence their distance perceptions. Although the informational specification of distance becomes redundant when people are active, paradoxically, many distance-related actions sidestep the need to perceive distance at all.  相似文献

This research investigates how contextual factors affect unethicality assessment of products. The research is conducted in the context of gifts and compares interpersonal gifts (IGs) and self-gifts (SGs) by examining individuals’ reactions in front of unethical gifts. Five experiments investigate how individuals assess product unethicality differently, depending on the source of the gift, being the Self or a gifter. This research employs attribution theory to explain the differences between IGs and SGs and identify psychological distance as a boundary condition for the effect.  相似文献

绿色消费虽然备受关注但消费者积极性却不高,这可能和个体差异性有关。为了考察绿色消费的积极性,本研究从个体差异的视角出发,引入购买时间距离这一变量,以揭示面对绿色产品的矛盾性消费者究竟更愿现在购买还是将来,决策模式是否会存在个体差异。研究发现,时间距离调节绿色消费观与产品购买意愿的关系,而产品价值感知部分中介了该调节作用。具体来说,绿色消费者不会受到时间框定的影响,而非绿色消费者则表现出时间框定效应即更倾向于在将来而不是现在购买绿色产品;这是因为绿色消费观以自上而下的方式影响绿色消费者动机加工,使绿色产品的价值感知较为稳定,而非绿色消费者的价值感知则根据购买时间距离的不同而变化。研究结果说明在生态文明建设日益紧迫的当下培育个体绿色消费观具有重要的意义。  相似文献

解释水平理论认为自我控制是人们依据对事件整体的高解释水平方式而非局部的低解释水平方式做出决策和完成任务。对时间折扣、坚持和健康行为以及前瞻性自我控制的研究表明高解释水平会促进自我控制。高解释水平是通过改变对诱惑的加工(包含对诱惑的态度和诱惑的激活模式)来促进自我控制, 但这种促进作用会受到目标和任务属性(重要性、难度、效价、完成时间和呈现方式)以及解释水平线索属性(外显和内隐)的调节。解释水平理论视角下的自我控制研究可以拓宽自我控制双系统理论和资源理论的视野, 如提供可能的边界条件和认知机制。未来研究还需要深入挖掘解释水平影响自我控制的内在机制和生理基础, 重视心理距离的影响以及加强对自控能力的长期追踪研究。  相似文献

回溯式时距估计是以记忆为主要成分, 且事后才知要对两个相继事件之间的间隔时间或某一事件持续时间的长短进行估计。可分为近时和远时的回溯式时距估计, 两者的计时机制与记忆有关, 但各有侧重:前者侧重短时或长时记忆, 直接证据来源于即时回忆单一或多个认知任务以估计时间, 间接证据则聚焦于物理、生理、心理因素的影响; 后者侧重自传体记忆, 可从问卷或访谈的测量方式以及主客体特征的影响两个方面来寻找证据。今后需以整合的观点深入探究回溯式时距估计的计时机制, 拓展回溯式时距估计行为测量的研究, 并开展对回溯式时距估计神经生物学基础的探讨。  相似文献

Why aggression?2     
On the basis of a formalised view of metapsychology, the author briefly considers the problems inherent in the Freudian notion of a death drive or aggressive drive and then goes on to develop a new theoretical conception of aggression. Aggression is understood as an affect, action or affective action and, in relation to these, as an expression of the intensity with which a drive'whether it be the sexual drive with its libidinal cathexes or the self‐preservative drive with its lethic cathexes'seeks to attain its object. In this context the author regards the regulation of closeness and distance with respect to the ‘psychogeometric locus’ of the relevant drive object as being of central importance. She contends that neurotic personalities suffer from specific distortions in the perception of the psychogeometric locus of their drive objects, which may give rise to an intensification of the drive tendencies prevailing in these individuals at any given time so that these tendencies take on an aggressive character. The author presents two clinical vignettes to show how her approach allows aggression and its occurrence to be conceptualised without resorting to the idea of a primary aggressive drive, and draws attention to the resulting technical consequences for interpretation.  相似文献
