Research over the last 25 years has demonstrated that animals are able to organize sequences in memory and retrieve ordered sequences without language. Qualitative differences have been found between the serial organization of behavior in pigeons and monkeys. Here the authors test serial ordering abilities in ring-tailed lemurs, a strepsirrhine primate whose ancestral lineage diverged from that of monkeys, apes, and humans approximately 63 million years ago. Lemurs' accuracy and response times were similar to monkeys, thus suggesting that they may share mechanisms for serial organization that dates to a common primate ancestor. 相似文献

Psychosocial treatments for chronic pain are effective. There is a need, however, to understand the processes involved in determining how these treatments contribute to behavior change. Control and acceptance strategies represent two potentially important processes involved in treatment, although they differ significantly in approach. Results from laboratory-based studies suggest that acceptance-oriented strategies significantly enhance pain tolerance and behavioral persistence, compared with control-oriented strategies. There is a need, however, to investigate processes of acceptance and control directly in clinical settings. The present study investigated the effects of three brief instructional sets (pain control, pain acceptance, continued practice) on demonstrated physical impairment in 74 individuals with chronic low back pain using an analogue experimental design. After controlling for baseline performance, the pain acceptance group demonstrated greater overall functioning on a set of 7 standardized physical tasks relative to the other two groups, which did not differ from one another. Further, the acceptance group exhibited a 16.3% improvement in impairment, whereas the pain control group worsened by 8.3% and the continued practice group improved by 2.5%. These results suggest that acceptance may be a key process involved in behavior change in individuals with chronic pain. 相似文献

Individuals prefer to receive information that is consistent with their attitudes. Three experiments examined whether attitude strength moderates this selective exposure effect. Experiments 1A and 1B found that participants preferred attitudinally consistent information but that this effect was more pronounced to the extent that the attitude was strongly held. Experiment 2 replicated these findings and ruled out an alternative interpretation that a general tendency to hold strong attitudes rather than issue-specific attitude strength moderates selective exposure. Discussion concerns the implications of these findings and the possibility that other variables moderate the selective exposure effect. 相似文献

How does the brain represent number and perform mathematical calculations? According to a recent and provocative study by Tang and colleagues, it depends on which language you learn. They found that the divergent linguistic and cultural experiences of native Chinese and native English speakers are associated with distinct patterns of brain activity during mathematical processing. Their results raise important questions about the cognitive and neural specificity of cultural influences on mathematical processes and the core nature of mathematical cognition. 相似文献

The problem of qualitative heterogeneity is to explain how an extended simple can enjoy qualitative variation across its spatial or temporal axes, given that it lacks both spatial and temporal parts. I discuss how friends of extended simples should address the problem of qualitative heterogeneity. I present a series of arguments designed to show that rather than appealing to fundamental distributional properties one should appeal to tiny and short-lived tropes. Along the way, issues relevant to debates about material composition, persistence over time and existence monism are discussed. 相似文献

Two experiments examined the puzzling variation in the age-related patterns for event-based prospective memory tasks. Both experiments involved a famous faces ongoing task with a feature of the famous face as the target for the prospective memory task. In Experiment 1, a substantial age deficit was found on the prospective memory task when the cue was nonfocal (wearing glasses) to the ongoing task, replicating previous research, but this deficit was significantly reduced with a focal cue (first name John). In Experiment 2, the prospective memory cue (wearing glasses) was held constant and the demands of the ongoing task of naming faces were varied. The substantial age differences found with a nonfocal cue were eliminated when the ongoing task was made less challenging. The findings help reconcile the divergent age-related findings reported in the literature. 相似文献

Realizing complex delayed intentions in young and old adults: The role of planning aids 总被引:1,自引:0,他引:1
Although it has been suggested that the delayed realization of intended actions should benefit from appropriate intention planning, empirical evidence on this issue is scarce. In three experiments, we examined whether and which planning aids provided in the intention formation phase affect delayed intention realization in young and old adults. One finding was that intention planning directly affected delayed intention realization: instructing participants to include the cue for appropriate intention initiation in their plans benefited delayed performance. Another finding was that older adults' performance was improved when they were guided in structuring their plan in combination with guidance in implementing this plan after a delay. In sum, the results point to the importance of plan-related factors for understanding the delayed realization of intended actions. 相似文献

This article summarizes the criterion-related and construct validity evidence for theEmployee Attitude Inventory (EAI) theft scales. These paper-and-pencil measures were designed to help employers gain information about theft among current employees. It is argued that the validity of the theft scales is dependent on the proportion of dishonest employees in the group being screened. Using meta-analysis techniques, the theft scales were shown to have useful levels of validity regardless of the proportion of dishonest employees in the population being screened. Also, the validity coefficients were relatively invariant across organizations and occupations. Thus the available evidence supports the use of the EAI as an effective tool for identifying dishonest employees. However, given that the present analyses are based on a relatively small set of data, the authors' conclusions should be regarded as preliminary. These analyses should be repeated as additional validity data becomes available.The opinions expressed in the report are those of the authors, and do not necessarily represent those of any organizations with which the authors are associated. 相似文献

College students responded under a multiple differential-reinforcement-of-low-rate 5-s fixed-ratio 8 schedule, with components alternating every 2 min. After 40 programmed minutes of acquisition and 12 min of maintenance, without notice, both schedules changed to extinction for 28 min. During acquisition, between alternations of the multiple schedule, some subjects were asked to develop rules describing the schedule contingencies. Other subjects were given these same rules between alternations, and a third group neither received nor were asked to develop rules. By the end of the acquisition phase, self-generated-rule subjects were more likely to show schedule-typical behavior than were subjects not asked to generate rules. The behavior of those given rules was similar to those asked to generate rules at the end of acquisition, but yoked-rule subjects acquired schedule-typical behavior at a quicker rate. By the end of extinction, during the period corresponding to the previous fixed-ratio interval, all no-rule subjects who had earned points during acquisition and maintenance were responding at a rate of less than 30 responses per minute. Only 3 of the 9 self-generated-rule subjects and 2 of the 5 yoked-rule subjects were similarly responding at this low rate. Results suggest that asking subjects to develop self-rules facilitates acquisition, but can retard extinction. Results also suggest that self-generated rules function similarly to external rules. 相似文献

Despite widespread interest in adolescent smoking behavior, little research has been directed to the social dynamics of adolescent smoking. In this paper, smoking intentions and peer group influences among a sample of 1,689 Grade 8 students from southern Ontario were analyzed to ascertain possible gender-specific correlates in adolescent smoking intentions. The peer environment was found to be a crucial factor in adolescent smoking behavior. Particularly striking for adolescent girls was the firmness of their expressed intentions to continue to smoke quite early in their smoking lives. 相似文献
