The debate over unitary/multiple category-learning utilities is reminiscent of debates about multiple memory systems and unitary/dual codes in knowledge representation. In categorization, researchers continue to seek paradigms to dissociate explicit learning processes (yielding verbalizable rules) from implicit learning processes (yielding stimulus–response associations that remain outside awareness). We introduce a new dissociation here. Participants learned matched category tasks with a multidimensional, information-integration solution or a one-dimensional, rule-based solution. They received reinforcement immediately (0-Back reinforcement) or after one intervening trial (1-Back reinforcement). Lagged reinforcement eliminated implicit, information-integration category learning but preserved explicit, rule-based learning. Moreover, information-integration learners facing lagged reinforcement spontaneously adopted explicit rule strategies that poorly suited their task. The results represent a strong process dissociation in categorization, broadening the range of empirical techniques for testing the multiple-process theoretical perspective. This and related methods that disable associative learning—fostering a transition to explicit-declarative cognition—could have broad utility in comparative, cognitive, and developmental science.  相似文献

Two sequential studies were conducted to test the notion that preperformance routines (PPRs) positively affect motor performance. The first study consisted of observations and interviews with 115 elite athletes to explore crucial time periods and body positions inherent in expert preparation for performing a golf putt, tennis serve, volleyball serve, and basketball free throw. In the second study, we taught these features of PPR to novice performers: 240 male and female high school students were assigned to two motor-mental PPR, and one control condition. Findings revealed that PPR enhances motor performance and can be implemented at an early stage of learning.  相似文献

This study examined the moderating role of perceived social support between perceived parenting styles and relational aggression (RA). A sample (= 400) was selected through stratified sampling from public and private schools and colleges. Adolescents (= 200 boys and = 200 girls) completed (a) Demographic Performa, (b) Early Memories of Upbringing for Children to measure perceived parenting styles, (c) Social Support Questionnaire to measure perceived social support, and (d) Diverse Adolescent Relational Aggression Scale to measure RA. Statistical analyses showed that perceived social support moderated the relationship between perceived parenting styles and RA. Findings indicated that perceived social support strengthens the negative relationship between perceived father’s Overprotection parenting and RA. Results also showed that perceived social support strengthens positive relationship between perceived father’s Anxious Rearing parenting and RA. Moreover, perceived social support strengthens the positive relationship between perceived mother’s Rejection parenting and RA. Results help in implementing interventions to promote the consolidation or increment of sources that constitute adolescents with concrete and feasible actions in the cultural, educational, and counseling implications.  相似文献

This paper explores the tenability of three important critiques to the ‘migrant network’ approach in migration studies: (1) the narrow focus on kin and community members, which connect prospective migrants in origin countries with immigrants in the destination areas, failing to take due account of sources of assistance beyond the ‘migrant network’ like institutional or online sources; (2) that it is misleading to assume a general pattern in the role of migrant networks in migration, regardless of contexts of arrival or departure, including the scale and history of migration or the immigration regime; and (3) that ‘migrant networks’ are not equally relevant to all migrants, and that important differences may exist between labour migrants and other types of migrants like family migrants or students. Drawing on survey data on the migration of Brazilians to Portugal and the Netherlands we find support for these critiques but also reaffirm the relevance of ‘migrant networks’.  相似文献

This study into female sex offenders examines the links between their sexual acting out and traumatic life events. The methodology is based on an analysis of 35 court cases involving females convicted of sexual abuse alongside semistructured interviews recorded with 13 participants. NVivo® software was used to analyze the data thematically, whence four key themes emerged (a desire for power, sadism, extreme anger, and the quest for self-affirmation); these themes fall into a typology that highlights the different contexts and characteristics of the sexual abuse. The results also highlight a traumatic context during childhood and adolescence that is likely to have formed the basis for the development of the deviant sexual behavior and the fact that all the women acted in collusion. The discussion on the results suggests that assessing and analyzing the needs of these women should focus in particular on the relationship between the current sexual acting out and a personal biography filled with traumatic events.  相似文献

This study focuses on retraction notices from two major Latin American/Caribbean indexing databases: SciELO and LILACS. SciELO includes open scientific journals published mostly in Latin America/the Caribbean, from which 10 % are also indexed by Thomson Reuters Web of Knowledge Journal of Citation Reports (JCR). LILACS has a similar geographical coverage and includes dissertations and conference/symposia proceedings, but it is limited to publications in the health sciences. A search for retraction notices was performed in these two databases using the keywords “retracted”, “retraction” “withdrawal”, “withdrawn”, “removed” and “redress”. Documents were manually checked to identify those that actually referred to retractions, which were then analyzed and categorized according to the reasons alleged in the notices. Dates of publication/retraction and time to retraction were also recorded. Searching procedures were performed between June and December 2014. Thirty-one retraction notices were identified, fifteen of which were in JCR-indexed journals. “Plagiarism” was alleged in six retractions of this group. Among the non-JCR journals, retraction reasons were alleged in fourteen cases, twelve of which were attributed to “plagiarism”. The proportion of retracted articles for the SciELO database was approximately 0.005 %. The reasons alleged in retraction notices may be used as signposts to inform discussions in Latin America on plagiarism and research integrity. At the international level, these results suggest that the correction of the literature is becoming global and is not limited to mainstream international publications.  相似文献

The Iowa gambling task (Bechara et al., Cognition 50:7–15, 1994) is designed to simulate a decision making problem under ambiguity, in which the degree of reliance on emotional cues arising from previous experiences contributes to perform advantageously. Recent studies based on the appraisal tendency framework demonstrated that emotional certainty (associated with intuitive strategies) leads to a more advantageous decision pattern, whereas emotional uncertainty (associated with deliberative strategies) impairs the performance in the IGT (Bagneux et al., Motivation and Emotion 37(4):818–827, 2013; Bollon and Bagneux, Cognition and Emotion 27(2):376–384, 2013). Due to the problems in the IGT (Dunn et al., Neuroscience and Biobehavioral Reviews 30:239–271, 2006; Steingroever et al., Psychological Assessment 25(1):180–193, 2013), however, it is an open question to what extent the disadvantageous IGT performance in the uncertainty conditions was based on risky decision making. Addressing the main criticisms on the IGT, the primary aim of the present study is to provide a further explanation for the underlying source of the IGT impairment led by uncertainty appraisals. In line with previous research, we found that participants in the certainty-associated emotion condition (disgust) outperformed those in uncertainty-associated conditions (fear, sadness) in the gambling game. Detailed four-deck format analyses on decision patterns and knowledge levels provided supporting evidence for our main hypothesis that the weak IGT scores in the uncertainty conditions can be summarized as a failure to anticipate the badness and the goodness of the most difficult decks, and a dominant preference for a risky option with high immediate gains and infrequent losses.  相似文献

In this study, individuals and interacting 3‐person groups were asked to make a series of allocation decisions using a modified version of the A&S decision case (Staw, 1976). Based on the choice‐shift effect, it was hypothesized that groups would allocate more to a failing course of action than would individuals, and that these differences would emerge only after repeated sequential decisions. Both hypotheses were supported. These findings suggest that processes unique to groups account for the greater allocations of groups, relative to individuals in escalation situations. The implications of these findings in applied settings are discussed.  相似文献
