Justification of effort is a form of cognitive dissonance in which the subjective value of an outcome is directly related
to the effort that went into obtaining it. However, it is likely that in social contexts (such as the requirements for joining
a group) an inference can be made (perhaps incorrectly) that an outcome that requires greater effort to obtain in fact has
greater value. Here we present evidence that a cognitive dissonance effect can be found in children under conditions that
offer better control for the social value of the outcome. This effect is quite similar to contrast effects that recently have
been studied in animals. We suggest that contrast between the effort required to obtain the outcome and the outcome itself
provides a more parsimonious account of this phenomenon and perhaps other related cognitive dissonance phenomena as well.
Research will be needed to identify cognitive dissonance processes that are different from contrast effects of this kind.

In a human predictive learning experiment, the strengths of ABA, ABC, and AAB recovery effects after discrimination reversal learning were compared. Initially, a discrimination between two stimuli (X+, Y−) was trained in Context A. During Phase 2, participants received discrimination reversal training (X−, Y+) either in Context A (Group AAB) or in Context B (Group ABA, Group ABC). Testing occurred in the reversal context and in a neutral context (Group AAB, Group ABC) or in the reversal context and in the acquisition context (Group ABA). Recovery effects were similar in ABA and ABC procedures, whereas no AAB recovery effect occurred. Furthermore, the rate of discrimination reversal learning during Phase 2 was unaffected by whether training was conducted in the same or in a different context as initial learning. Results indicate that contextual stimuli are processed before interfering information is presented. These representations, however, do not acquire the ability to control performance. 相似文献

Pinto, Olivers, and Theeuwes (2006) showed that a static target can be efficiently found among different types of dynamically changing distractors. They hypothesized that attention employs a broad division between static and dynamic information, a hypothesis that conforms with earlier research. In the present study, we investigated whether attention can only make use of this crude division or can exploit more subtle discriminations within the dynamic domain. In Experiment 1, participants were able to efficiently find a blinking target among moving distractors and moving targets among blinking distractors, although all items changed at the same rate and produced the same change in local luminance. In Experiment 2, search for a dynamic target among dynamic distractors was aided when we gave the distractors additional dynamic cues. Experiment 3 showed that making the displays equiluminant affected search efficiency for a static target among moving distractors, but not among blinking distractors. The findings refute the broad division hypothesis and suggest that object continuity plays an important role in selection. 相似文献

Colours and consciousness both present us with metaphysical problems. But what exactly are the problems? According to standard accounts, they are roughly the following. On the one hand, we have reason to believe, about both colour and consciousness, that they are identical with some familiar natural phenomena. But on the other hand, it is hard to see how these identities could obtain. I argue that this is an adequate characterisation of our metaphysical problem of colour, but a mischaracterisation of the problem of consciousness. It mischaracterises the problem by presenting consciousness as more ‘colour-like’ than we have reason to take it to be. The real problem of consciousness is, I suggest, that almost nothing theoretically useful is known about this phenomenon at present. I also explore some implications of this perspective on the problem of consciousness. Given the shape of the problem, I argue that we can’t rule out all forms of eliminativism about consciousness. Nor can we rule out that future research will close the ‘explanatory gap’ that consciousness gives rise to. 相似文献

This study examined the effects of case‐specific facts and individual discomfort with ambiguity (DA) on investigators' beliefs concerning effective interviewing tactics for suspects. Violent crime investigators (n = 30) responded to a questionnaire including the Need for Closure Scale (NFCS) and ratings of the importance of 39 interrogation tactics in two hypothetical interrogations with a homicide suspect, where the evidence consisted of either technical evidence or soft information. Twenty tactics were analysed with a multidimensional scaling procedure which confirmed two discrete interviewing themes: humane and dominant. More tactics, both dominant and humane, were rated as important if the evidence was soft compared with technical. In the soft evidence condition, investigators who were high on DA rated both types of tactics as more important than did low‐DA investigators. In the technical evidence condition, no such difference emerged. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

We often feel that our perceptual experience is richer than what we can express. For instance, when flashed with a large set of letters, we feel that we can see them all, while we can report only a few. However, the nature of this subjective impression remains highly debated: while many favour a dissociation between two forms of consciousness (access vs. phenomenal consciousness), others contend that the richness of phenomenal experience is a mere illusion. Here we addressed this question with a classical partial-report paradigm now modified to include unexpected items in the unreported parts of the stimuli. We show that even in the presence of unexpected pseudo-letters, participants still felt that there were only letters. Additionally, we show that this feeling reflects an illusion whereby participants reconstruct letters using partial letter-like information. We propose that the feeling of seeing emerges from the interplay between partially accessible information and expectations. 相似文献

Relying on the theoretical model of [Lyubomirsky et al. 2005, Review of General Psychology, 9, pp. 111–131], the present study
investigated the relationship between personality, number of friends, best friendship quality and happiness among 423 young
adults (n = 300 women). The main interest was to examine whether friendship contributed to happiness while controlling for personality.
Friendship variables accounted for 58% of the variance in happiness. Results revealed that friendship quality predicted happiness
above and beyond the influence of personality and number of friends, but friendship conflict was not a significant predictor.
Additional analyses revealed that the companionship and self-validation features of friendship quality were predictive of
happiness while controlling for gender and personality. The findings were discussed in the light of theory and empirical research
and suggestions were made for future research.

Research has found that neighborhood structural characteristics can influence residents' mental health. Few studies, however, have explored the proximal reasons behind such influences. This study investigates how different types of communities, in terms of environmental stressors (social and physical disorder and fear of crime) and social resources (informal ties and formal organizational participation), affect well-being, depression, and anxiety in adult residents. Data are from a survey of 412 residents nested in 50 street blocks. Block stressors and resources were cluster analyzed to identify six block types. After controlling for several individual- and block-level characteristics, results from multilevel models suggest that in communities facing relatively few stressors, higher levels of formal participation are associated with better mental health. Because high levels of formal participation were not found in communities with higher levels of stressors, the impact of participation in such contexts could not be examined. However, results suggest that in communities where stressors are more common, isolation from neighbors may have a protective effect on mental health. 相似文献
