Implicit learning involves picking up information from the environment without explicit instruction or conscious awareness of the learning process. In nonhuman animals, conscious awareness is impossible to assess, so we define implicit learning as occurring when animals acquire information beyond what is required for successful task performance. While implicit learning has been documented in some nonhuman species, it has not been explored in prosimian primates. Here we ask whether ring‐tailed lemurs (Lemur catta) learn sequential information implicitly. We tested lemurs in a modified version of the serial reaction time task on a touch screen computer. Lemurs were required to respond to any picture within a 2 × 2 grid of pictures immediately after its surrounding border flickered. Over 20 training sessions, both the locations and the identities of the images remained constant and response times gradually decreased. Subsequently, the locations and/or the identities of the images were disrupted. Response times indicated that the lemurs had learned the physical location sequence required in original training but did not learn the identity of the images. Our results reveal that ring‐tailed lemurs can implicitly learn spatial sequences, and raise questions about which scenarios and evolutionary pressures give rise to perceptual versus motor‐implicit sequence learning.  相似文献

This study integrates three theoretical perspectives provided by social identity theory, realistic group conflict theory, and social dominance theory to examine the relationship between religious identification and interreligious contact. It relies on a unique dataset collected among Christian and Muslim students in ethnically and religiously diverse regions of Indonesia and the Philippines, where social cleavages occur along religious lines. Religious identification directly predicts a higher quality of interreligious contact, whereas it indirectly predicts a lower quantity and quality of contact, mediated by higher perception of group threat, and a higher quality of contact, mediated by lower social dominance orientation. Furthermore, these direct and indirect relationships are moderated by religious group membership and relative group size. We conclude that religious identification functions as a ‘double‐edged sword’ predicting both higher quality and lower quantity and quality of interreligious contact through various pathways and with a varying strength depending on intergroup context.  相似文献

The present two studies investigated whether toddlers’ ability to use pictures in problem solving could be facilitated by making available the social context in which pictures were created. To make this social context available, we introduced an Experimental treatment in which the creator was intentionally drawing different objects. In Experiment-1, due to this treatment, children performed better in the Test in which the Experimenter was drawing the Test-pictures of the retrieval task. In Experiment-2, after the same Experimental treatment the facilitative effect was replicated although the social context was removed in the Test phase by using pre-drawn Test-pictures without any drawing action in the retrieval task. The results suggest that a treatment which offers the opportunity to understand the socially mediated representational function of pictures enables children to perform better when contextualizing pictures in current reality. These two experiments revealed a novel way to facilitate children’s picture comprehension by identifying an underlying factor that can explain children’s difficulty in picture comprehension.  相似文献

Past research has found that when victims are ingroup members, observers’ social identification interacts with general belief in a just world (GBJW) to predict judgments about those victims. In this correlational study (N = 284 women, ages from 18 to 80) we aimed to test whether and how women’s explicit endorsement of BJW, both personal belief in a just world (PBJW) and GBJW, interacts with their identification as women to predict wife abuse legitimization.We predicted and found that the interaction between PBJW and social identification predicted legitimization of wife abuse. Specifically, for highly identified women, PBJW was positively associated with wife abuse legitimization, for less identified women, PBJW was not associated with wife abuse legitimization. This interaction was significant above and beyond other variables associated with this phenomenon: hostile and benevolent sexism, empathy (cognitive and emotional), and social desirability. On the contrary, the interaction between GBJW and social identification was a nonsignificant predictor of legitimization of wife abuse. These results contribute to reconceptualize the role of PBJW and GBJW on judgments about victims and to highlight the importance of considering the victimization situations in the social context and the social groups in which they actually occur.  相似文献

Theories of relational concept acquisition (e.g., schema induction) based on structured intersection discovery predict that relational concepts with a probabilistic (i.e., family resemblance) structure ought to be extremely difficult to learn. We report four experiments testing this prediction by investigating conditions hypothesized to facilitate the learning of such categories. Experiment 1 showed that changing the task from a category‐learning task to choosing the “winning” object in each stimulus greatly facilitated participants' ability to learn probabilistic relational categories. Experiments 2 and 3 further investigated the mechanisms underlying this “who's winning” effect. Experiment 4 replicated and generalized the “who's winning” effect with more natural stimuli. Together, our findings suggest that people learn relational concepts by a process of intersection discovery akin to schema induction, and that any task that encourages people to discover a higher order relation that remains invariant over members of a category will facilitate the learning of putatively probabilistic relational concepts.  相似文献

While many aspects of cognition have been investigated in relation to skilled music training, surprisingly little work has examined the connection between music training and attentional abilities. The present study investigated the performance of skilled musicians on cognitively demanding sustained attention tasks, measuring both temporal and visual discrimination over a prolonged duration. Participants with extensive formal music training were found to have superior performance on a temporal discrimination task, but not a visual discrimination task, compared to participants with no music training. In addition, no differences were found between groups in vigilance decrement in either type of task. Although no differences were evident in vigilance per se, the results indicate that performance in an attention-demanding temporal discrimination task was superior in individuals with extensive music training. We speculate that this basic cognitive ability may contribute to advantages that musicians show in other cognitive measures.  相似文献

Attention bias modification (ABM) aimed at correcting dysfunctional biases in anxiety patients has met with only mild success. Inspired by recent studies showing large effects of financial reward upon attention shifts, we contrasted effects of traditional dot-probe ABM and reward upon attention biases in a between-subject 2 × 2 design. Twenty-seven participants in group cognitive behavioural therapy (GCBT) for social anxiety disorder (SAD) were randomly assigned to undergo six sessions of a dot-probe task consisting of ABM or placebo ABM along with random or high reward following neutral stimuli. There was no influence of ABM on participants' attention bias over and above the influence of GCBT. Reward, however, had a strong influence on attention bias. Neither ABM nor reward reduced SAD symptoms over and above the effects of GCBT. The results add to the growing evidence that benefits of ABM through dot-probe training are unreliable but suggest on the other hand that rewarding attention may strongly influence dysfunctional attention biases.  相似文献

This study examines the utility of two widely advocated methods for supporting judgmental forecasts—providing task feedback and providing judgmental bootstrapping support. In a simulated laboratory based experiment that focused on producing composite sales forecasts from three individual components, we compared the effectiveness of these two methods in improving final judgmental forecasts. In the presence of cognitive feedback task, feedback led to better forecasts than providing judgmental bootstrap forecasts. Simply providing bootstrap forecasts was of no additional benefit over a control condition. This was true in terms of the Brunswik Lens model measures of achievement, knowledge, and consistency, and in terms of forecast accuracy. This occurred both in stable environments and when special events (unusual one‐time events requiring adjustments to the forecasts) arose. Copyright © 2005 John Wiley & Sons, Ltd.  相似文献
