The present study reports two experiments in which a total of 20 participants without prior flight experience practiced the final approach phase in a fixed-base simulator. All participants received self-controlled concurrent feedback during 180 practice trials. Experiment 1 shows that participants learn more quickly under variable practice conditions than under constant practice conditions. This finding is attributed to the education of attention to the more useful informational variables: Variability of practice reduces the usefulness of initially used informational variables, which leads to a quicker change in variable use, and hence to a larger improvement in performance. In the practice phase of Experiment 2 variability was selectively applied to some experimental factors but not to others. Participants tended to converge toward the variables that were useful in the specific conditions that they encountered during practice. This indicates that an explanation for variability of practice effects in terms of the education of attention is a useful alternative to traditional explanations based on the notion of the generalized motor program and to explanations based on the notions of noise and local minima. 相似文献

How can shared music preferences create social bonds between people? A process model is developed in which music preferences as value-expressive attitudes create social bonds via conveyed value similarity. The musical bonding model links two research streams: (a) music preferences as indicators of similarity in value orientations and (b) similarity in value orientations leading to social attraction. Two laboratory experiments and one dyadic field study demonstrated that music can create interpersonal bonds between young people because music preferences can be cues for similar or dissimilar value orientations, with similarity in values then contributing to social attraction. One study tested and ruled out an alternative explanation (via personality similarity), illuminating the differential impact of perceived value similarity versus personality similarity on social attraction. Value similarity is the missing link in explaining the musical bonding phenomenon, which seems to hold for Western and non-Western samples and in experimental and natural settings. 相似文献

In this study, we used a paradigm similar to the one used by Milgram in his classic obedience study, using an immersive video environment. We manipulated the victim's degree of visibility and his ethnicity. When the victim was hidden, the level of obedience we obtained was similar to Milgram's. Replicating previous findings observed in real environments, participants were more obedient when the victim was hidden than when he was visible, and the more obedient participants negated their own responsibility by projecting responsibility on both the victim and the experimenter. State‐anger and right‐wing authoritarianism (RWA) emerged as two significant predictors of the level of obedience. Illustrating an underlying process of racial‐dehumanization, participants reported less anxiety and distress when the victim was a North African than when the victim was of the same racial origin as the participant. These results underscore the usefulness of using immersive environments when studying extreme social behaviors. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

Research suggests that adolescents’ engagement in nonsuicidal self-injurious (NSSI) behaviors may be increasing over time,
yet little is known regarding distal longitudinal factors that may promote engagement in these behaviors. Data from two longitudinal
studies are presented to examine whether NSSI may be associated with peer influence processes. Study 1 included 377 adolescents
from a community-based sample; Study 2 included 140 clinically-referred adolescents recruited from a psychiatric inpatient
facility. In Study 1, adolescents’ NSSI was examined at baseline and one year later. Adolescents’ nominated best friend reported
their own levels of NSSI. In Study 2, adolescents’ NSSI was examined at baseline as well as 9 and 18-months post-baseline.
Adolescents’ perceptions of their friends’ engagement in self-injurious behavior (including suicidality) and depressed mood
also were examined at all three time points. Baseline depressive symptoms were measured in both studies; gender and age were
examined as moderators of peer influence effects. Results from both studies supported longitudinal peer socialization effects
of friends’ self-injurious behavior on adolescents’ own NSSI for girls, but not for boys, even after controlling for depressive
symptoms as a predictor. Study 1 suggested socialization effects mostly for younger youth. Results from Study 2 also suggested
longitudinal socialization effects, as well as peer selection effects; adolescents’ NSSI was associated with increasing perceptions
of their friends’ engagement in depressive/self-injurious thoughts and behavior. Findings contribute to the nascent literature
on longitudinal predictors of NSSI and to work on peer influence. 相似文献

The executive processes are well known to decline with age, and similar data also exists for attentional capacities and processing speed. Therefore, we investigated whether these two last nonexecutive variables would mediate the effect of age on executive functions (inhibition, shifting, updating, and dual-task coordination). We administered a large battery of executive, attentional and processing speed tasks to 104 young and 71 older people, and we performed mediation analyses with variables showing a significant age effect. All executive and processing speed measures showed age-related effects while only the visual scanning task performance (selective attention) was explained by age when controlled for gender and educational level. Regarding mediation analyses, visual scanning partially mediated the age effect on updating while processing speed partially mediated the age effect on shifting, updating and dual-task coordination. In a more exploratory way, inhibition was also found to partially mediate the effect of age on the three other executive functions. Attention did not greatly influence executive functioning in aging while, in agreement with the literature, processing speed seems to be a major mediator of the age effect on these processes. Interestingly, the global pattern of results seems also to indicate an influence of inhibition but further studies are needed to confirm the role of that variable as a mediator and its relative importance by comparison with processing speed. 相似文献

The progressive demasking (PDM) task is a perceptual identification task using degraded stimulus presentation procedures, but with the advantage of providing response time (RT) measures on each trial. Participants simply press a response button whenever they recognize a word. In this article, we present newly developed, easy-to-use freeware for PDM. Considering the difficulty of programming such a paradigm with standard experimental software, we developed a program based on high-level C libraries to be executed on Windows XP computers. The program execution is millisecond accurate forRT measurements and generates the fewest possible display duration errors. 相似文献

Historical accounts of the social sciences have too often accepted local or national institutions as a self-evident framework of analysis, instead of considering them as being embedded in transnational relations of various kinds. Evolving patterns of transnational mobility and exchange cut through the neat distinction between the local, the national, and the inter-national, and thus represent an essential component in the dynamics of the social sciences, as well as a fruitful perspective for rethinking their historical development. In this programmatic outline, it is argued that a transnational history of the social sciences may be fruitfully understood on the basis of three general mechanisms, which have structured the transnational flows of people and ideas in decisive ways: (a) the functioning of international scholarly institutions, (b) the transnational mobility of scholars, and (c) the politics of trans-national exchange of nonacademic institutions. The article subsequently examines and illustrates each of these mechanisms. 相似文献

We say that a semantical function is correlated with a syntactical function F iff for any structure A and any sentence we have A F
A .It is proved that for a syntactical function F there is a semantical function correlated with F iff F preserves propositional connectives up to logical equivalence. For a semantical function there is a syntactical function F correlated with iff for any finitely axiomatizable class X the class
–1X is also finitely axiomatizable (i.e. iff is continuous in model class topology). 相似文献

To account for the size effect in numerical comparison, three assumptions about the internal structure of the mental number
line (e.g., Dehaene, 1992) have been proposed. These are magnitude coding (e.g., Zorzi & Butterworth, 1999), compressed scaling
(e.g., Dehaene, 1992), and increasing variability (e.g., Gallistel & Gelman, 1992). However, there are other tasks besides
numerical comparison for which there is clear evidence that the mental number line is accessed, and no size effect has been
observed in these tasks. This is contrary to the predictions of these three assumptions. Moreover, all three assumptions have
difficulties explaining certain symmetries in priming studies of number naming and parity judgment. We propose a neural network
model that avoids these three assumptions but, instead, uses place coding, linear scaling, and constant variability on the
mental number line. We train the model on naming, parity judgment, and comparison and show that the size effect appears in
comparison, but not in naming or parity judgment. Moreover, no asymmetries appear in primed naming or primed parity judgment
with this model, in line with empirical data. Implications of our findings are discussed. This work was supported by Grant

Mere ownership effect is the phenomenon that people tend to value what they own more than what they do not own. This classic effect is considered robust, yet effect sizes vary across studies, and the effect is often confused for or confounded with other classic phenomena, such as endowment or mere exposure effects. We conducted a pre-registered meta-analysis of 26 samples published before 2019 (N = 3024), which resulted in psychological ownership on valuing effect of g ∼ 0.57 [0.46, 0.69]. Suggestive moderator analyses supported the use of replica as the strongest moderators. Mere ownership effects were different from the null across all moderator categories and in most publication bias adjustments. We consider this as suggestive evidence that psychological owning leads to valuing, yet caution that much more research is needed.
