In this study, we examined variables modulating interference effects on episodic memory under divided attention conditions during retrieval for a list of unrelated words. In Experiment 1, we found that distracting tasks that required animacy or syllable decisions to visually presented words, without a memory load, produced large interference on free recall performance. In Experiment 2, a distracting task requiring phonemic decisions about nonsense words produced a far larger interference effect than one that required semantic decisions about pictures. In Experiment 3, we replicated the effect of the nonsense-word distracting task on memory and showed that an equally resource-demanding picture-based task produced significant interference with memory retrieval, although the effect was smaller in magnitude. Taken together, the results suggest that free recall is disrupted by competition for phonological or word-form representations during retrieval and, to a lesser extent, by competition for semantic representations. 相似文献

This paper brings some data to bear on the criticisms, claims, and arguments that Skinner (a) denied or dismissed biological participation in behavior, (b) addressed it only late in his career or more often later than earlier, or (c) addressed it only because of the overwhelming evidence for it or the criticisms that he had overlooked it. For this, we coded Skinner's every primary-source publication for three content categories (i.e., genetics, physiology, and evolution) and for the extent to which he addressed them (i.e., in publication titles, substantively, or in passing). Our findings are that Skinner addressed biological participation in over a third of his publications throughout his career, albeit more often later than earlier. The latter, however, is accounted for by an increase in his base rate of publication and in general conditions and specific events in his career, psychology, and science. The discussion addresses our research methods; the reasons for and refutations of the criticisms, claims, and arguments; and their sources. 相似文献

When given suggestive information, some people can be led to believe that they had experiences that they did not actually have. For example, they may come to believe falsely that they got sick eating particular foods as children, and as a result of that belief they may avoid the foods. But how do we know that someone has developed a false belief or memory in this research? The criteria we choose when classifying whether someone has fallen for the suggestion are somewhat arbitrary. We reanalyze our prior data, using different criteria for deciding that a person fell for the suggestion (called a "believer") or did not (called a "non-believer"). Changing criteria obviously affects the percentage of people who are called susceptible and could conceivably affect the conclusions reached about that group. Comparisons between false memories and true memories could differ, too, depending on how memories are defined. 相似文献

In this study, the authors sought to determine whether abnormalities exhibited by schizophrenia patients in event-related potentials associated with self-monitoring--the error-related negativity (ERN) and the correct response negativity (CRN)--persist under conditions that maximize ERN amplitude and to examine relationships between the ERN and behavior in schizophrenia. Participants performed a flanker task under 2 contingencies: one encouraging accuracy and another emphasizing speed. Compared with healthy participants, in schizophrenia patients the ERN was reduced in the accuracy condition, and the CRN was enhanced in the speed condition. The amplitude of a later ERP component, the error positivity, did not differ between groups in either task condition. Reduced self-correction and increased accuracy following errors were associated with larger ERNs in both groups. Thus, ERN generation appears to be abnormal in schizophrenia patients even under conditions demonstrated to maximize ERN amplitude; however, functional characteristics of the ERN appear to be intact. 相似文献

Although unconditioned stimulus (US) magnitude influences conditioning, no experiment has addressed whether it influences a decision point at which the organism first responds (Gallistel & Gibbon, 2000). Two appetitive conditioning experiments with rats confirmed that the rate of food cup entries and proportion of head jerking were related to the number of pellets (US) provided after the conditioned stimulus. In addition, the onset of responding measured by the number of reinforcers to a criterion or by a quantitatively identified change point also reflected US magnitude. Two aversive conditioning experiments also found that the amount and onset of freezing were related to footshock intensity. All experiments identified a trial at which responding increased abruptly in individual subjects. However, the point where the increase occurred was earlier with larger USs. 相似文献

This study examined level of acculturation, openness in communication with parents, peer interaction, and self-esteem in two ethnic groups-Asian and Caucasian American adolescents who grew up in the same neighborhood. The findings provide evidence of significant ethnic differences in behavioral patterns, peer networks, family contexts, and levels of self-esteem. In general, Asian adolescents expressed more difficulty discussing problems with their parents when compared to their Caucasian counterparts. Further, self-esteem was found to be significantly lower among Asians than Caucasians. Implications for the provision of mental health services are discussed. 相似文献

The Bell Object Relations Inventory (BORI; Bell,1995) is a self-report instrument that measures deficits in object relations ego functioning. It has demonstrated clinical and research utility in adult populations. This article reports the development of a version of the BORI for children ages 11 to 17, including studies of reliability, validity, and factorial invariance. Data of 705 children from public schools and 110 children from clinics and residential treatments were used. Of the 45 original BORI true/false items, 3 were dropped as inappropriate and most others were rewritten for easier reading. An additional 16 items were created to capture unique features of adolescent experiences in relationships. Items were tested in focus groups and revised accordingly. Eight items were dropped because of low communalities, so that 50 items were included in the final factor analysis. Assessments using self-report items from Behavioral Assessment Scale for Children (BASC; Reynolds & Camphaus, 1992) and the Personality Inventory for Youth (PIY) were also obtained to test concurrent validity. Oblique rotation yielded 5 factors. Four were very similar to the 4 from the adult version and were named accordingly: Alienation, Insecure Attachment, Egocentricity, and Social Incompetence. The fifth scale was comprised mostly of new items and was called Positive Attachment. Scales showed excellent factorial invariance and good internal consistency. Scales generally had very low intercorrelations reflecting their relative independence. Although differences were found for gender and race, the effect sizes were small. Support for construct validity came from moderate correlations with concurrent BASC and PIA scores, analyses of variance showing greater deficits in object relations in pathological subgroups compared with normals, and a trend analysis showed that Alienation scores followed a lawful relationship with increasing severity of psychopathology. These initial findings support the psychometric integrity of the instrument and its construct validity. Results indicate continuity of constructs between the adult and adolescent versions. The Positive Attachment subscale may prove a valuable addition for clinical and research applications. 相似文献

In the last two decades the integrative role of the frontal premotor cortex (a mosaic of agranular/disgranular areas lying in front of the primary motor cortex) have been more and more elucidated. Among its various functions, sensorimotor transformation, and action representation storage, also for nonstrictly motor purposes, are the most intriguing properties of this region, as shown by several researches. In this article we will mainly focus on the ventro-rostral part of the monkey premotor cortex (area F5) in which visual information describing objects and others' acting hands are associated with goal-directed motor representations of hand movements. We will describe the main characteristics of F5 premotor neurons and we will provide evidence in favor of a parallelism between monkeys and humans on the basis of new experimental observations. Finally, we will present some data indicating that, both in humans and in monkeys, action-related sensorimotor transformations are not restricted to visual information but concern also acoustic information. 相似文献

These comments address Laties', Dewsbury's, and Rutherford's papers on the extension and application of Skinner's operant psychology during the 1950s. I begin by reflecting on the papers' overall theme-that the success of behavior analysis lies in its practical applications-and add some comments on Planck's principle. I then turn to the three papers and address such topics as (a) other applications and extensions (e.g., the U.S. space program), (b) relations between the research and researchers at the Yerkes Laboratories of Primate Biology (e.g., a Yerkes' researcher in Skinner's laboratory), and (c) human schedule performance (e.g., continuity and discontinuity with nonhuman behavior). I end with a discussion of the fundamental reason for the success of the extensions and applications of behavior analysis-the experimental analysis of behavior. 相似文献
