Across four studies, people sat (or reported they would sit) closer to physically similar others. Study 1 revealed significant aggregation in seating patterns on two easily observed characteristics: glasses wearing and sex. Study 2 replicated this finding with a wider variety of physical traits: race, sex, glasses wearing, hair length, and hair color. The overall tendency for people to sit beside physically similar others remained significant when controlling for sex and race, suggesting people aggregate on physical dimensions other than broad social categories. Study 3 conceptually replicated these results in a laboratory setting. The more physically similar participants were to a confederate, the closer they sat before an anticipated interaction when controlling for sex, race, and attractiveness similarity. In Study 4, overall physical similarity and glasses wearing similarity predicted self-reported seating distance. These effects were mediated by perceived attitudinal similarity. Liking and inferred acceptance also received support as mediators for glasses wearing similarity. 相似文献

The current study looked at two theoretical proposals explaining toddlers’ abilities to use cue information for recovering a hidden object that had rolled down a ramp behind an occluded screen. These two approaches, the theory of object directed attention and a landmark-based account, make different predictions regarding the efficacy of an obliquely aligned cue to object position. Accordingly, the search by forty 24-month olds, forty-two 30-month olds, and forty-one 36-month olds for a hidden toy that was cued using either a short versus a long cue, or a vertically aligned versus an obliquely aligned cue, were compared. Analyses of search accuracy revealed that children were more successful when faced with short as opposed to long cues, and when using vertical as opposed to oblique cues. These findings support a landmark-based approach, as opposed to an object-directed attention account, and are discussed with reference to their implications for spatial orientation more generally. 相似文献

Behaviour on even simple experimental games shows considerable individual differences, but previous attempts to link these preferences to stable personality traits have had mixed results. Here we address three limitations of earlier studies, namely: (1) uncertainties concerning the reliability of preferences; (2) use of personality instruments with limited cross-study comparability; and (3) confounds where more than one psychological motive can lead to a particular choice. Sixty-seven participants completed 12 distinct real-money games twice over a two-week interval along with 6 measures concerning their expectations about other players’ choices. Personality was measured using the full NEO-PI-R. Choices were highly stable across time (r = .84). Moreover, choices on the 12 games and 6 expectations reflected a single underlying dimension of “prosocial orientation”, measuring concern for the payoffs received by other players. Scores on the prosocial orientation dimension were related to personality, with openness, (low) neuroticism, and (low) extraversion retained as significant predictors. 相似文献

Past research on the relationship between affect and creativity has yielded contradictory results. Most of the evidence has tended to show that brief positive emotions as well as more enduring positive moods enhance creativity. No study to date, however, has attempted to determine whether the influence of momentary emotions on creativity depends on pre-existing moods. In the present study, 96 undergraduates completed one of two creative tasks (generating or evaluating captions for photographs) on three occasions, after watching videos designed to induce positive, neutral, or negative emotions. Participants also completed a questionnaire assessing depressed mood. Results confirmed that the effect of emotion inductions on creativity depended on pre-existing mood. Participants low in depression wrote more creative captions and rated captions more accurately with induced negative emotion than with induced positive emotion. In contrast, participants high in depression appeared impervious to the effect of emotion inductions. 相似文献

Youth with neurofibromatosis type 1 (NF1) have multiple, complex symptoms associated with physical, social-emotional, and cognitive difficulties. In addition, caring for a child with NF1 can be extremely challenging for parents. Since research with other chronic illness populations suggests that social support, including internet support groups (ISGs), can be beneficial, this survey study aimed to determine the attitudes and preferences of adolescents and young adults with NF1 and parents of a child with NF1 regarding ISGs. Thirty patients and 30 caregivers completed a 24-item survey about ISGs. Many patients and parents are not aware of any ISGs for NF1, but are interested in using one in the future for a variety of reasons, including to get answers to their questions about NF1, to find out about research studies, and to discuss problems and concerns about NF1. Specific concerns of interest include physical, social-emotional, and cognitive aspects of NF1. ISGs have potential as a social support intervention within the NF1 community. ISGs for the NF1 population should include patients with NF1 (or parents of children with NF1) as well as a health professional, and both chat rooms and discussion boards likely would be well-received. 相似文献

Parental maturity refers to parents’ ability to see their child as an independent adult with limitations and needs, and relate to him/her accordingly. In this study, we had two main aims: (a) develop a measure of parental maturity and test its construct validity in a sample of middle-aged parents with an emerging adult child, and (b) examine how the dimensions of parental maturity varied with a child’s gender and life course transitions (i.e., employment and leaving the parental home). A sample of 343 Portuguese parents (187 mothers and 156 fathers) aged 40–68 participated in this study. Factorial validity of the Parental Maturity Measure was tested using exploratory and confirmatory factor analyses and measurement invariance across mothers and fathers. Results gave support for a two-factor measure—Comprehending (6 items) and Letting Go (4 items)—with an equivalent meaning across parents. Dimensions of parental maturity were associated with differentiated and positive parent–child relationship qualities, but were quite independent of the child’s gender and life course transitions. 相似文献

The presentation of a Bayesian inference problem in terms of natural frequencies rather than probabilities has been shown to enhance performance. The effect of individual differences in cognitive processing on Bayesian reasoning has rarely been studied, despite enabling us to test process-oriented variants of the two main accounts of the facilitative effect of natural frequencies: The ecological rationality account (ERA), which postulates an evolutionarily shaped ease of natural frequency automatic processing, and the nested sets account (NSA), which posits analytical processing of nested sets. In two experiments, we found that cognitive reflection abilities predicted normative performance equally well in tasks featuring whole and arbitrarily parsed objects (Experiment 1) and that cognitive abilities and thinking dispositions (analytical vs. intuitive) predicted performance with single-event probabilities, as well as natural frequencies (Experiment 2). Since these individual differences indicate that analytical processing improves Bayesian reasoning, our findings provide stronger support for the NSA than for the ERA. 相似文献

The circular movement of migrants between their homelands and adopted countries has problematized the previous linear understanding of return migration. However, the concept of circular migration tends to apply to migrants whose movement is enabled by their extensive pre-migration connections with their homelands. In this paper, we report findings of a study on a group of new-generation Chinese–Canadian youth working in Hong Kong. Although, like many return migrants, this group of young people had economic reasons for moving to Hong Kong (their parents' homeland), they do not position themselves as return migrants. Instead, they have kept a strong Canadian identity by maintaining unique friendship circles and perceiving Canada as a home to which they will one day return. We highlight in this paper some implications of their experiences for transnational migration studies. 相似文献
