Consumers may suppress their feelings toward the attractive looks of products when they wish to minimize the influence of feelings on their judgments and choices. However, this research suggests that feeling suppression may result in a paradoxical reliance on feelings in product judgments and choices, especially when the product performance judgment is difficult to make. Findings from a series of experiments suggest that this paradoxical effect stems from the requisite resource input for feeling suppression and the consequent resource competition with functionality processing which then impairs product performance judgment.  相似文献

The study examined whether face‐specific perceptual brain mechanisms in 9‐month‐old infants are differentially sensitive to changes in individual facial features (eyes versus mouth) and whether sensitivity to such changes is related to infants' social and communicative skills. Infants viewed photographs of a smiling unfamiliar female face. On 30% of the trials, either the eyes or the mouth of that face were replaced by corresponding parts from a different female. Visual event‐related potentials were recorded to examine face‐sensitive brain responses. Results revealed that increased competence in expressive communication and interpersonal relationships was associated with a more mature response to faces, as reflected in a larger occipito‐temporal N290 with shorter latency. Both eye‐ and mouth changes were detected, though infants derived different information from these features. Eye changes had a greater impact on the face perception mechanisms and were not correlated with social or communication development, whereas mouth changes had a minimal impact on face processing but were associated with levels of language and communication understanding.

This study tested the Bayesian journey-to-crime (JTC) model by gender and age for serial offenders from Manchester, England. The data were 4056 crimes committed by 171 serial offenders between 2003 and 2006. The data were subdivided by gender and age group to examine whether accuracy and precision varied by these subgroups. In general, the centre of minimum distance was found to be the most accurate measure, but the Bayesian risk and product measures were found to be the most precise measurements. The traditional ‘distance decay’ type of JTC function did not produce estimates that are as accurate nor as precise as the Bayesian approach. Tests were conducted on whether specific gender and age group JTC functions and origin–destination matrices improved predictability. With the exception of juvenile male offenders, the general functions were more accurate and precise. In terms of building an accurate and precise geographical profiling methodology, the results point to the need to include information on the likely predisposition of neighbourhoods to produce offenders as well as information on the crime opportunities available to offenders.

Visual search in children and adults: top-down and bottom-up mechanisms   总被引:1,自引:0,他引:1  
Three experiments investigated visual search for targets that differed from distractors in colour, size, or orientation. In one condition the target was defined by a conjunction of these features, while in the other condition the target was the odd one out. In all experiments, 6-7- and 9-10-year-old children were compared with young adults. Experiment 1 showed that children's search differed from adults' search in two ways. In conjunction searches children searched more slowly and took longer to reject trials when no target was present. In the odd-one-out experiments, 6-7-year-old children were slower to respond to size targets than to orientation targets, and slower for orientation targets than for colour targets. Both the other groups showed no difference in their rate of responding to colour and orientation. Experiments 2 and 3 highlighted that these results were not a function of either differential density across set sizes (Experiment 2) or discriminability of orientation and colour (Experiment 3). Across all three experiments, the results of both conjunction and odd-one-out searches highlighted a development in visual search from middle to late childhood.  相似文献

Many people tend to believe that natural categories have perfectly predictive defining features. They do not easily accept the family resemblance view that the features characteristic of a category are not individually sufficient to predict the category. However, common category-learning tasks do not produce this simpler-than-it-is belief. If there is no simple classification principle in a task, the participants know that fact and can report it. We argue that most category-learning tasks in which family resemblance categories are used fail to produce the everyday simpler-than-it-is belief because they encourage analysis of identification criteria during training. To simulate the learning occurring in many natural circumstances, we developed a procedure in which participants' analytic activity is diverted from the way in which the stimuli are identified to the use to which the stimuli will be put. Finally, we discuss the prevalence of this diverted analysis in everyday categorization.  相似文献

Three experiments were conducted to test the phonological recoding hypothesis in visual word recognition. Most studies on this issue have been conducted using mono-syllabic words, eventually constructing various models of phonological processing. Yet in many languages including English, the majority of words are multi-syllabic words. English includes words incorporating a silent letter in their letter strings (e.g., champane). Such words provide an opportunity for investigating the role of phonological information in multi-syllabic words by comparing them to words that do not have the silent letter in the corresponding position (e.g., passener). The performance focus is on the effects of removing letters from words with a silent letter and from words with a non-silent letter. Three representative lexical tasks—naming, semantic categorization, lexical decision—were conducted in the present study. Stimuli that excluded a silent letter (e.g., champa_ne) were processed faster than those that excluded a sounding letter (e.g., passen_er) in the naming (Experiment 1), the semantic categorization (Experiment 2), and the lexical decision task (Experiment 3). The convergent evidence from these three experiments provides seminal proof of phonological recoding in multi-syllabic word recognition. An erratum to this article can be found at  相似文献

The ability of welfare-to-work clients to leave the welfare rolls and stay in the labor force is often limited by the work barriers they face. Using a sample of 1,404 female welfare-to-work clients we first examined the structure of work barriers and then tested their contribution to current work status in the context of a structural equation model that incorporated other central pathways to employment. Whereas work barriers included diverse factors ranging from lack of transportation to low quality jobs, they were shown to constitute a uni-dimensional construct. Furthermore, work barriers had a net adverse effect on employment outcomes, controlling for job search self-efficacy and employment intention. We conclude with discussion of implications for the development of welfare-to-work programs and interventions that target low-income women.  相似文献

The authors examine the within-individual dynamics of Big-5 personality states over time in people's daily lives. They focus on the magnitude of this within-individual variability, and the associations between personality states, short-term goals, and subjective well-being states. A total of 101 undergraduate students participated in a 10-day interval-contingent diary study. The authors' findings, based on multilevel procedures, establish a considerable amount of within-individual variability that is both (a) equal or larger than that observed between individuals and (b) larger or similar to other constructs assessed with a state approach (e.g., self-esteem and mood). In addition, both neuroticism and extraversion states are systematically related to the short-term pursuit of approach-avoidance goals. Finally, support was obtained for the mediating role of both neuroticism and extraversion states of the association between goals and subjective well-being. In sum, the authors' findings testify to the importance and utility of studying within-individual variability in personality states over time.  相似文献
