In an experimental study involving German lay judges, law students and controls, effects of legal training and experience as well as information amount on legal judgments was investigated. In a three (legal knowledge: legal training versus legal experience versus controls) x two (information amount: high versus low) between‐subjects design, 137 participants judged the premeditation of a perpetrator in eight real‐world cases decided by the German Federal Court of Justice. Judgment congruency with the Court's ruling increased with legal training, but official lay judges showed lower congruency compared with student controls. Additionally, legal training and experience corresponded with higher confidence. Emotional reactions to the legal cases were stronger when more information was given for individuals without legal training but decreased for individuals with training. An information‐processing perspective to explain the observed differences in legal judgments is advanced, and the issue of using untrained individuals in the legal decision making process is discussed.

Whereas much is known about how we categorize and reason based on absolute quantity, data exploring ratios of quantities, as in proportions and fractions, are comparatively sparse. Until recently, it remained elusive whether these two representations of number are connected, how proportions are implemented by neurons and how language shapes this code. New data derived with complementary methods and from different model systems now shed light on the mechanisms of magnitude ratio representations. A coding scheme for proportions has emerged that is remarkably reminiscent of the representation of absolute number. These novel findings suggest a sense for ratios that grants the brain automatic access to proportions independently of language and the format of presentation. 相似文献

Threatening faces involuntarily grab attention in socially anxious individuals. It is unclear, however, whether attention capture is at the expense of concurrent visual processing. The current study examined the perceptual cost effects of viewing fear-relevant stimuli (threatening faces) relative to a concurrent change-detection task. Steady-state visual evoked potentials (ssVEPs) were used to separate the neural response to 2 fully overlapping types of stimuli flickering at different frequencies: Task-irrelevant facial expressions (angry, neutral, happy) were overlaid with a task-relevant Gabor patch stream, which required a response to rare phase reversals. Groups of 17 high and 17 low socially anxious observers were recruited through online prescreening of 849 students. A prominent competition effect of threatening faces was observed solely in elevated social anxiety: When an angry face, relative to a neutral or happy face, served as a distractor, heightened ssVEP amplitudes were seen at the tagging frequency of that facial expression. Simultaneously, the ssVEP evoked by the task-relevant Gabor grating was reliably diminished compared with conditions with neutral or happy distractor faces. Thus, threatening faces capture and hold low-level perceptual resources in viewers symptomatic for social anxiety at the cost of a concurrent primary task. It is important to note that this competition in lower tier visual cortex was maintained throughout the viewing period and was unaccompanied by competition effects on behavioral performance.

When deciding for whom to vote, voters should select the candidate they expect to best handle issues, all other things equal. A simple heuristic predicted that the candidate who is rated more favorably on a larger number of issues would win the popular vote. This was correct for nine out of ten U.S. presidential elections from 1972 to 2008. We then used simple linear regression to relate the incumbent's relative issue ratings to the actual two‐party popular vote shares. The resulting model yielded out‐of‐sample forecasts that were competitive with those from the Iowa Electronic Markets and established quantitative models. The issue‐index model has implications for political decision makers, as it can help to track campaigns and to decide which issues to focus on. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

Previous studies on attentional biases often show contradictory results. This suggests that important moderating variables have been neglected so far. We suggest that (1) control over potential consequences and (2) satisfaction with the current status are important factors that need to be considered. We explored the influence of these variables using a colour classification task, where colours are associated with financial gains and losses. Data were analysed with hierarchical logistic regression models and with stochastic diffusion models. The latter approach has the special advantage that it allows separating perceptual and judgemental biases. Results show an overall positive judgemental bias. In the absence of control, this positivity bias increases with the amount of money that has been gained, whereas the opposite pattern is present when dangers can be controlled. In the second experiment, no general feedback was given, which led to an increasing negativity bias. Results are discussed within an action theoretic framework. 相似文献

A newly developed Semantic Misattribution Procedure (SMP), a semantic variant of the Affect Misattribution Procedure (AMP), was used in three studies as an indirect measure of sexual interest. Using a known-group approach, homosexual men (Studies 1 and 2), heterosexual men (Studies 1 to 3) and heterosexual women (Study 3) were asked to guess the meaning of briefly presented Chinese ideographs as “sexual” or “not sexual”. The ideographs were preceded by briefly presented primes depicting male and female individuals of varying sexual maturity. As hypothesised, the frequency of “sexual” responses increased after priming with pictures of individuals of the preferred sex and increasing sexual maturation. The SMP showed satisfactory reliability and convergent validity as indicated by correlations with direct and two indirect measures of sexual interest. In two further studies, the hypothesised pattern was replicated whereas a standard AMP with the identical prime stimuli did not produce this result. The potential usefulness of semantic variants of the AMP is discussed. 相似文献

Abstract There is tremendous interest in understanding the cognitive processes behind obsessive–compulsive disorder (OCD). Whereas previous research on cognitive OCD models has focused on the dysfunctional content of obsessional thinking, processes and styles of thinking have not yet been investigated. The present study investigated the relationship between a ruminative response style and obsessive–compulsive (OC) symptomatology in two non-clinical samples. In Sample 1, 261 students completed the Ruminative Response Scale, the Padua-Inventory, Revised, and the Beck Depression Inventory. Tendency to ruminate was positively correlated with the severity of OC symptoms and particularly with obsessive rumination, even after controlling for depression. Results were replicated in Sample 2 (211 students). Data indicate that a ruminative response style and obsessive rumination share common processual features. Understanding the interaction between rumination and obsessional thinking might help to further elucidate the role of cognitive vulnerability factors in OCD and to expand cognitive and metacognitive models of OCD. 相似文献

Trauma survivors with posttraumatic stress disorder (PTSD) often experience psychosocial problems. This article reviews interpersonal factors such as social support, social acknowledgment, and interpersonal impairment that are relevant to the development and maintenance of PTSD. Furthermore, it considers the possible impact of social cognition on PTSD. The capacity to empathize (empathy) and the existence of an individual “theory of mind” are fundamental to human social interaction. We raise the question of whether traumatic experiences may lead to changes in the social cognition of traumatized individuals. The possible effects of perceived social exclusion as a maintenance factor for PTSD are also discussed. 相似文献

In two experiments coupling between dorsal attentional selection for action and ventral attentional selection for perception during preparation of prehension movements was examined. In a dual-task paradigm subjects had to grasp an X-shaped object with either the left or the right hand's thumb and index finger. Simultaneously a discrimination task was used to measure visual attention prior to the execution of the prehension movements: Mask items transiently changed into distractors or discrimination targets. There was exactly one discrimination target per trial, which appeared at one of the four branch ends of the object. In Experiment 1 target position varied randomly while in Experiment 2 it was constant and known to subjects in each block of trials. In both experiments discrimination performance was significantly better for discrimination target positions at to-be-grasped branch ends than for not-to-be-grasped branch ends. We conclude that during preparation of prehension movements visual attention is largely confined to those parts of an object that will be grasped. 相似文献
