In the Deese/Roediger-McDermott (DRM) paradigm, studying lists of semantic associates results in high rates of false recognition of a nonpresented critical word. The present set of experiments was designed to measure the contribution of additional processing of list items at test to this false memory effect. The participants studied sets of lists and then performed a recognition task for each set. In three experiments, using this paradigm, we investigated false recognition when the number of studied list items presented at test (0, 6, or 12) was manipulated. In Experiments 2 and 3, false recognition of critical lures associated to both studied and nonstudied lists increased significantly as the number of list items included in the test increased. These results indicate that processes occurring at retrieval contribute to false memory effects found with the DRM paradigm. 相似文献

The Immediate and Delayed Memory Tasks are variations of the Continuous Performance Test. While previous research with the tasks has focused on group performance across multiple blocks and sessions, reliability estimates have not been established. We estimated reliability (1) between blocks of a single testing session (N=106), (2) across four sessions within a single testing day (N=20), and (3) across sessions on four consecutive testing days (N=20). Analyses indicated that the primary variable of interest, i.e., commission of errors, showed acceptable reliability within and across testing periods. 相似文献

Speed discrimination tasks were used to examine the spatial and temporal characteristics of the integration mechanism involved when signals are extended in the direction of motion. We varied the aspect ratio of a signal patch whose speed differed from the background, while holding the area of the signal patch constant, so that the signal patch could be either extended in the direction of motion or extended orthogonal to the direction of motion. Speed discrimination thresholds decreased dramatically as the signal patch was extended in the direction of motion. The spatial and temporal integration regions were larger than would be expected if the integration mechanism were a low-level motion detector. The mechanism was tuned for direction of motion. The data are discussed with reference to two alternative integration mechanisms: a low-level detector that is elongated in the direction of motion and a higher level integration mechanism characterized by cooperative or facilitatory interactions between low-level detectors tuned to the same direction of motion. Our data are consistent with a second-level, direction-specific process that integrates the responses of low-level motion detectors. 相似文献

False memory in a short-term memory task 总被引:1,自引:0,他引:1
The Deese/Roediger-McDermott (DRM; Roediger & McDermott, 1995) paradigm reliably elicits false memories for critical nonpresented words in recognition tasks. The present studies used a Sternberg (1966) task with DRM lists to determine whether false memories occur in short-term memory tasks and to assess the contribution of latency data in the measurement of false memories. Subjects studied three, five, or seven items from DRM lists and responded to a single probe (studied or nonstudied). In both experiments, critical lures were falsely recognized more often than nonpresented weak associates. Latency data indicated that correct rejections of critical lures were slower than correct rejections of weakly related items at all set sizes. False alarms to critical lures were slower than hits to list items. Latency data can distinguish veridical and false memories in a short-term memory task. Results are discussed in terms of activation-monitoring models of false memory. 相似文献

The present study used a multiple baseline across participants design to assess whether 4 children with autism could learn a generalized repertoire of helping adults with different tasks through the use of a multicomponent teaching package. Different helping responses were taught in the presence of multiple exemplars of discriminative stimuli drawn from experimenter-defined categories of helping behavior (e.g., locating objects, putting away items, setting up an activity). During the training condition, video models, prompting, and reinforcement were used. The results showed that all 4 children learned to emit appropriate helping responses in the presence of discriminative stimuli from the helping categories used during training. Generalization of helping responses was observed in the presence of untrained discriminative stimuli during additional probe conditions. Additional pre- and postintervention generalization trials showed that the frequency of helping responses also increased in the presence of novel stimuli, in a novel setting, and with a novel instructor. 相似文献

In this research, we propose that emotions are affected not only by appraisals, but also by a metacognitive sense of confidence versus doubt over the appraisals. Focusing on core-relational themes (CRTs), higher-order appraisals comprising the combined meaning of several appraisals, we predicted and found evidence, over two studies, that the effect of a CRT on the corresponding emotion is stronger if one feels confident about the validity of the CRT compared to feeling doubtful. In Study 1, CRT was manipulated by recall and in Study 2, CRT was manipulated in vivo. Both designs produced consistent support for the hypotheses. These findings demonstrate the need to consider metacognitive processes in understanding the effects of appraisals on emotions. 相似文献

Prevailing wisdom is that increased visibility of gay men and lesbians reduces levels of sexual prejudice, but less is known about who is more likely to ally with the gay community and how interaction with the gay community influences attitudes toward gay men and lesbians. Using data from 873 heterosexual college students in the US, we examine how alliance with the gay community, a typology which combines measures of personal contact and community contact, relates to attitudes towards gay men and lesbians. Membership in each alliance category differed by gender, race/ethnicity, size of place, traditional gender role and authoritarian attitudes, religiosity, and political conservatism. Approximately one-third of the sample are allies of the gay community with both personal contact and community contact and lower levels of sexual prejudice. By contrast, another 30 % of the sample has no contact (personal or community) and higher levels of sexual prejudice toward the gay community. We conclude that more complex models of heterosexual contact with gay community are more useful than dichotomous models for understanding differences in attitudes towards gay men and lesbians. 相似文献

Using boundary theory and conservation of resources theory, we examined how job incumbents’ perceptions of supervisor instrumental support and organizational segmentation support influence outcomes for both the incumbent and the spouse. First, we examined how supervisor instrumental support and organizational segmentation support shape incumbents’ perceived ability to flex work boundaries and thus affect their experience of family functioning and their organizational commitment. Second, we examine the effects of supervisor instrumental support and organizational segmentation support on spousal martial satisfaction and the spouse's commitment to the incumbent's employing organization as mediated through boundary flexibility and the spouse's perception of successful boundary management by the incumbent. Using a matched set of 503 subordinates and their spouses, this study found that both supervisor instrumental support and organizational segmentation support contribute to work boundary flexibility. Further, for the incumbent, family functioning and organizational commitment were enhanced through work boundary flexibility, whereas for the spouse, marital satisfaction and commitment to the incumbent's organization were enhanced through both incumbent work boundary flexibility and the spouse's perception of successful boundary management by the incumbent. We discuss the study's implications for theory, research, and practice while suggesting new research directions. 相似文献
