The concept of self is central to personhood, but personality research has largely ignored the relevance of recent advances in self-concept theory: multidimensionality of self-concept (focusing instead on self-esteem, an implicit unidimensional approach), domain specificity (generalizability of trait manifestations over different domains), and multilevel perspectives in which social-cognitive processes and contextual effects drive self-perceptions at different levels (individual, group/institution, and country) aligned to Bronfenbrenner's ecological model. Here, we provide theoretical and empirical support for psychological comparison processes that influence self-perceptions and their relation to distal outcomes. Our meta-theoretical integration of social and dimensional comparison theories synthesizes five seemingly paradoxical frame-of-reference and contextual effects in self-concept formation that occur at different levels. The effects were tested with a sample of 485,490 fifteen-year-old students (68 countries/regions, 18,292 schools). Consistent with the dimensional comparison theory, the effects on math self-concept were positive for math achievement but negative for verbal achievement. Consistent with the social comparison theory, the effects on math self-concept were negative for school-average math achievement (big-fish-little-pond effect), country-average achievement (paradoxical cross-cultural effect), and being young relative to year in school but positive for school-average verbal achievement (big-fish-little-pond effect—compensatory effect). We demonstrate cross-cultural generalizability/universality of support for predictions and discuss implications for personality research. © 2020 European Association of Personality Psychology  相似文献

People often have difficulty in understanding processes of biological change, and they typically reject drastic life cycle changes such as metamorphosis, except for animals with which they are familiar. Even after a lesson about metamorphosis, people often do not generalize to animals not seen during the lesson. This might be partially due to the perceptual richness of the diagrams typically used during lessons on metamorphosis, which serves to emphasize the individual animal rather than a class of animals. In two studies, we examined whether the perceptual richness of a diagram influences adults' learning and transfer of knowledge about metamorphosis. One study was conducted in a laboratory setting, and the other was online. In both studies, adults who saw the bland diagram during the lesson accurately transferred more than adults who saw the rich diagram during the lesson.  相似文献

Imagined contact can be effective at reducing social stigma. However, the effect may depend on the strength of the stigma held. We tested the robustness of imagined contact in an Asian setting where stigmatization of mental illness is stronger than in Western countries. In Experiment 1 (n = 167) with five conditions, only an enhanced version of positive imagined contact was able to decrease stigma towards people with schizophrenia through decreasing intergroup anxiety. Given the potential discrepancy between imaginations and reality about experiences with stigmatized groups, in Experiment 2 (n = 121), we tested the hypothesis that after presenting participants with factual information about a mental illness group, imagined contact might backfire, resulting in more negative perceptions. However, enhanced imagined contact alongside factual message about schizophrenia did not increase stigma. The backfiring hypothesis was therefore not supported. Nevertheless, providing realistic information did negate the positive effects of enhanced imagined contact on stigma reduction. In both experiments, we also showed that intergroup anxiety mediated the effect of enhanced imagined contact on various measures of stigma.  相似文献

Incremental validity testing (i.e., testing whether a focal predictor is associated with an outcome above and beyond a covariate) is common (e.g., 57% of Personal Relationships articles in 2017), yet it is fraught with conceptual and statistical problems. First, researchers often use it to overemphasize the novelty or counterintuitiveness of findings, which hinders cumulative understanding. Second, incremental validity testing requires that the focal predictor and the covariate represent separate constructs; researchers risk committing the “jangle fallacy” without such evidence. Third, the most common approach to incremental validity testing (i.e., standard multiple regression, 88% of articles) inflates Type I error and can produce invalid conclusions. This article also discusses the relevance of these issues to dyadic/longitudinal designs and offers concrete solutions.  相似文献

ABSTRACT

When people recognize faces, they normally move their eyes so that their first fixation is in the optimal location for efficient perceptual processing. This location is found just below the centre-point between the eyes. This type of attentional bias could be partly innate, but also an inevitable developmental process that aids our ability to recognize faces. We investigated whether a group of people with developmental prosopagnosia would also demonstrate neurotypical first fixation locations when recognizing faces during an eye-tracking task. We found evidence that adults with prosopagnosia had atypically heterogeneous first fixations in comparison to controls. However, differences were limited to the vertical, but not horizontal, plane of the face. We interpret these findings by suggesting that subtle changes to face-based eye movement patterns in developmental prosopagnosia may underpin their face recognition impairments, and suggest future work is still needed to address this possibility.  相似文献
