According to the cognitive liberalization hypothesis, exposure to intergroup contact improves cognitive outcomes related to open-mindedness and out-of-the-box thinking. In a sample of Italian adults (N = 708), we: (a) investigated the profile of cognitive liberalization through a latent profile analysis including cognitive (i.e., cognitive flexibility, socio-cognitive mindfulness, curiosity and low need for structure) and socio-cultural (i.e., deprovincialization, beliefs supporting societal diversity and low social dominance orientation [SDO]) dimensions of cognitive liberalization; (b) tested how intergroup contact experiences differed between the profile of cognitive liberalization and the other profiles. Results showed three profiles: Cognitive Liberalization (high scores in both cognitive and socio-cultural dimensions of cognitive liberalization), Cognitive Rigidity (low scores on cognitive, high scores in socio-cultural dimensions) and Anti-Liberalization (low scores on all liberalization variables). Individuals belonging to the Cognitive Liberalization profile reported less negative, and more positive and intimate contact experiences with the outgroup compared with the other two profiles; they had a higher proportion of outgroup members in their acquaintances, and perceived those outgroup members involved in positive contact as more representative of their outgroup. Diversity of contacted outgroup members did not matter for the profiles. Close and positive relationships with the outgroup could be key to cognitive liberalization.

The developmental course of neural tuning to visual letter strings is unclear. Here we tested 39 children longitudinally, at the beginning of grade 1 (6.45 ± 0.33 years old) and 1 year after, with fast periodic visual stimulation in electroencephalography to assess the evolution of selective neural responses to letter strings and their relationship with emerging reading abilities. At both grades, frequency‐tagged letter strings were discriminated from pseudofont strings (i.e. letter‐selectivity) over the left occipito‐temporal cortex, with effects observed at the individual level in 62% of children. However, visual words were not discriminated from pseudowords (lexical access) at either grade. Following 1 year of schooling, letter‐selective responses showed a specific increase in amplitude, a more complex pattern of harmonics, and were located more anteriorly over the left occipito‐temporal cortex. Remarkably, at both grades, neural responses were highly significant at the individual level and correlated with individual reading scores. The amplitude increase in letter‐selective responses between grades was not found for discrimination responses of familiar keyboard symbols from pseudosymbols, and was not related to a general increase in visual stimulation responses. These findings demonstrate a rapid onset of left hemispheric letter selectivity, with 1 year of reading instruction resulting in increased emerging reading abilities and a clear quantitative and qualitative evolution within left hemispheric neural circuits for reading.  相似文献

Three studies explored how the traits that people ideally desire in a romantic partner, or ideal partner preferences, intersect with the process of romantic relationship initiation and maintenance. Two attraction experiments in the laboratory found that, when participants evaluated a potential romantic partner's written profile, they expressed more romantic interest in a partner whose traits were manipulated to match (vs. mismatch) their idiosyncratic ideals. However, after a live interaction with the partner, the match vs. mismatch manipulation was no longer associated with romantic interest. This pattern appeared to have emerged because participants reinterpreted the meaning of the traits as they applied to the partner, a context effect predicted by classic models of person perception (S. E. Asch, 1946). Finally, a longitudinal study of middle-aged adults demonstrated that participants evaluated a current romantic partner (but not a partner who was merely desired) more positively to the extent that the partner matched their overall pattern of ideals across several traits; the match in level of ideals (i.e., high vs. low ratings) was not relevant to participants' evaluations. In general, the match between ideals and a partner's traits may predict relational outcomes when participants are learning about a partner in the abstract and when they are actually in a relationship with the partner, but not when considering potential dating partners they have met in person.  相似文献

This study examined young women??s expectations about gender equality in their future careers and marriages. The study implemented a possible selves method in which 114 undergraduate women from a Midwestern university in the United States were randomly assigned to envision themselves as married mothers employed either full-time, part-time, or not at all and possessing either an advanced degree or a bachelor??s degree. Participants indicated their expectations for gender equality by estimating their own and their future husbands?? expected salaries and hours per week of housework and employment. They also evaluated their possible selves and estimated their emotional well-being and likely attainment of several important life goals. Greater employment produced greater expected gender equality, although in all conditions participants expected to have lesser salary and more domestic work than their husbands. With employment, compared with no employment, and with an advanced degree, compared with a bachelor??s degree, participants rated their possible selves more positively and estimated that they would have greater emotional well-being and attainment of life goals related to respect and finances. However, employment negatively affected participants?? anticipated relationships with their children. Thus, our participants?? reactions displayed a tradeoff between satisfying their employment goals and their goals for their relationship with their children.  相似文献

Roncato and Casco (2003, Perception & psychophysics 65 1252-1272) had shown that in situations where the Gestalt principle of good continuity is put into conflict with preservation of contrast polarity (CP) the perception that preserves CP prevails. Parlangeli and Roncato (2010, Perception 39 255-259) have studied this question of preservation of CP more closely and have added an addendum to the rule. They have used stimuli consisting of a checkerboard of perpendicularly arranged rectangular bricks (white, gray, or black) and draughtsmen white, gray, or black disks placed at the corners of the bricks. This study has caused them to add an addendum to the rule of CP-preserved path-conjunction binding: if there are two contour completions that preserve the CP, the one with the higher contrast will prevail. Parlangeli and Roncato find that, for certain shades of the disks and bricks, the perpendicular lines of the checkerboard appear strikingly to be slanted or undulating. Here we consider all possible arrangements of relative magnitudes of checkerboards consisting of bricks of two different shades and disks of two shades as well, as such arrangements with widely varying differences in the magnitude of brightness. We have found a number of cases where the perception is not explained by the rule and addendum of Roncato and Casco, and Parlangeli and Roncato, and a case where preservation of "distant" as well as local CP plays a role in perception. The previously known cases, and the new exceptional unexplained stimuli we have found, warrant further study.  相似文献

Over the last several years, direct to consumer(DTC) genetic testing has received increasing attention in the public, healthcare and academic realms. DTC genetic testing companies face considerable criticism and scepticism,particularly from the medical and genetic counseling community. This raises the question of what specific aspects of DTC genetic testing provoke concerns, and conversely,promises, for genetic counselors. This paper addresses this question by exploring DTC genetic testing through an ethic allens. By considering the fundamental ethical approaches influencing genetic counseling (the ethic of care and principle-based ethics) we highlight the specific ethical concerns raised by DTC genetic testing companies. Ultimately,when considering the ethics of DTC testing in a genetic counseling context, we should think of it as a balancing act. We need careful and detailed consideration of the risks and troubling aspects of such testing, as well as the potentially beneficial direct and indirect impacts of the increased availability of DTC genetic testing. As a result it is essential that genetic counselors stay informed and involved in the ongoing debate about DTC genetic testing and DTC companies. Doing so will ensure that the ethical theories and principles fundamental to the profession of genetic counseling are promoted not just in traditional counseling sessions,but also on a broader level. Ultimately this will help ensure that the public enjoys the benefits of an increasingly genetic based healthcare system.  相似文献

Activity in the posterior parietal cortex (PPC) has been shown to be a strong correlate of successful recognition performance. We assessed the degree to which the PPC mediates metacognitive judgments by assessing the feeling of knowing (FOK) for recently learned (episodic) and well-learned (semantic) facts (e.g., "The sport that is associated with Wimbledon is . . ."). Activity in ventral regions of the PPC was observed for strong FOKs for both sets of facts, although greater activity was observed for episodic than for semantic facts. Strong semantic FOKs activated anterior temporal regions. Weaker FOK ratings, when contrasted with strong FOKs, activated dorsal parietal regions, a finding that parallels contrasts during explicit tests in which low-confident responses were compared with high-confident responses. These findings demonstrate retrieval-related parietal activity during metacognitive judgments. Furthermore, they show that the ventral PPC is particularly engaged during context-specific, episodic retrieval, as compared to semantic retrieval.  相似文献

Two experiments examined transfer of a prospective, time production skill under conditions involving changes in concurrent task requirements. Positive transfer of the time production skill might be expected only when the attentional demands of the concurrent task were held constant from training to test. However, some positive transfer was found even when the concurrent task at retraining was made either easier or more difficult than the concurrent task learned during training. The amount and direction of transfer depended more on the pacing of the stimuli in the secondary task than on the difficulty of the secondary task, even though difficulty affects attentional demands more. These findings are consistent with the procedural reinstatement principle of skill learning, by which transfer from one task to another depends on an overlap in procedures required by the two skills.  相似文献

Any technique that conserves classroom instructional time without sacrificing the amount learned is of great educational value. This research compared a laboratory analogue of the clicker technique to analogues of other classroom pedagogical methods that all involve repeated testing during teaching. The clicker analogue mimics the classroom practice of dropping material that is understood by the majority of the class, as revealed by testing with clicker questions, from further lecture. A fact learning and retrieval paradigm was used, in which college students learned facts about unfamiliar countries. Compressing instruction time based on group-level performance produced as much learning as no compression and as compression based on individual-level performance. Results suggest that the clicker technique is an efficient and cost-effective method of conserving instructional time without loss of amount learned.  相似文献
