The current status of research on the memory drum theory is evaluated with emphasis on the issues raised by Marteniuk and MacKenzie (1981). A general theme emerging from this review is that response programming is not the only process which can influence RT and that distinguishing programming from non-programming effects clarifies rather than “clouds? the issues. 相似文献

Kindergarten and first-grade children giving nonintentional moral judgments were divided into three equated groups (Ns = 6), in each of two studies. Two groups performed with models (adult or peer) giving intentionality responses, with the third a control. During training, three Ss and three models in a group performing alternately were given social reinforcement for intentionality responses to Piaget-type stories. On an immediate posttest, both training groups in each study showed significant intentionality response gains from pretest and significantly exceeded their control group (ps < .05), while not differing significantly from each other. In study #2, a delayed posttest showed similar training durability for both training groups; both increased nonsignificantly in intentionality responses, continuing to exceed the controls (ps < .05). 相似文献

The present study investigated the effect of haloperidol-induced mood in normal healthy male volunteers on the retrieval of memories of real-life personal experiences using a between-subjects double-blind design. Forty subjects were required to retrieve past real life experiences associated with a series of stimulus words following administration of a single oral dose of 5mg haloperidol or placebo. The experiences were subsequently rated by subjects for their happiness felt at the time of the original experience. A significant decline in self-reported hedonic tone was observed in subjects given haloperidol. In addition, subjects on placebo recalled a significantly greater percentage of happy memories than subjects who were on haloperidol; a trend for a reverse pattern was observed for unhappy memories. The effects of the drug on the retrieval of memories were only in part mediated by the decline in hedonic tone scores. The effects of haloperidol are interpreted in terms of drug-induced dysphoria. 相似文献

This work examines ways to make the best use of limited resources when selecting individuals to follow up in a longitudinal study estimating causal effects. In the setting under consideration, covariate information is available for all individuals but outcomes have not yet been collected and may be expensive to gather, and thus only a subset of the comparison participants are followed. Expressions in Rubin and Thomas (1996) show the benefits that can be obtained, in terms of reduced bias and variance of the estimated treatment effect, of selecting comparison individuals well matched to those in the treated group compared with a random sample of comparison individuals. We primarily consider nonexperimental settings but also consider implications for randomized trials. The methods are illustrated using data from the Johns Hopkins University Baltimore Prevention Program, which included data collection from age 6 to young adulthood of participants in an evaluation of 2 early elementary-school-based universal prevention programs. 相似文献

The demise of Christendom is of fundamental significance in understanding the present and future relationship between the churches and European culture. Attempts to develop post-Christendom perspectives are hindered by linguistic and conceptual confusion. This article explores misleading implications of the terms ‘post-Constantinian’ and ‘post-Christian’ and argues for the consistent use of the term ‘post-Christendom’. Use of the terms ‘Christendom’ and ‘post-Christendom’ has been criticised for failing to differentiate between different kinds of Church–state partnerships, some of which may be less problematic than others. This article acknowledges such historical differences but argues that there is an underlying ideological unity susceptible of being described and investigated under these labels. It argues further that attempts to promote a benign expression of Christendom as a possible future for Europe are unwise. It summarises the transitions occurring as Europe journeys beyond Christendom and argues for creative engagement with post-Christendom as an opportunity for ecclesial renewal. 相似文献

Abstract This paper investigates athletes' perception of the relationship between cognitive interference and its effects on concentration and effort during sport performance. The sample consisted of 115 volleyball players that took part in a national university tournament. Three different kinds of thoughts were investigated: ‘performance worries’, ‘situation-irrelevant thoughts’, and ‘thoughts of escape’. Path analysis was used to examine the relationships. All kinds of thoughts were reported to be detrimental to concentration, whereas different patterns of associations emerged between different thoughts and subsequent effort. ‘Performance worries’ were reported to be related to increases in effort for athletes holding higher goal attainment expectancies and decreases in effort for athletes holding lower goal attainment expectancies. ‘Thoughts of escape’ were reported to be related to decreases in effort, while no significant relation between ‘situation irrelevant thoughts’ and effort emerged. Results stress the importance of further examining the role of interfering thoughts athletes experience during competition. 相似文献

Childhood abuse and dating violence victimization are prevalent and devastating problems. Although there has been an abundance of research on these topics in recent years, researchers and institutional review boards often struggle with determining whether asking respondents questions on previous violence will result in increased emotional distress or other negative research outcomes. Empirical data are therefore needed that examine the research reactions of individuals who participate in research on childhood abuse and dating violence. This study examined this topic among a sample of male college students (N?=?193). Results showed that victims of childhood sexual abuse had more negative emotional reactions and victims of physical dating violence had more negative perceived drawbacks to research participation than nonvictims. However, victims and nonvictims did not differ on positive research reactions. These findings suggest that there are few differences between victims and nonvictims on research reactions. 相似文献

Set shifting difficulties and weak central coherence are information-processing biases associated with thinness-oriented eating and body image pathology in women. However, little is known about the relationship between these processing biases and muscularity-oriented eating and body image pathology. We investigated whether set shifting and central coherence were uniquely related to the drive for muscularity and muscularity-oriented disordered eating in a sample of 91 male undergraduates. Participants completed the Wisconsin Card Sort Test, the Matching Familiar Figures Task, the Drive for Muscularity scale, and a modified Eating Disorders Examination-Questionnaire. Results indicated that set shifting difficulties and weak central coherence were both uniquely positively associated with the drive for muscularity, and that set shifting difficulties were uniquely positively associated with muscularity-oriented disordered eating. Results are discussed with regard to the male experience of body image and eating pathology, and in regard to muscle dysmorphia. 相似文献

The syllable and the morpheme are known to be important linguistic variables, but is such information involved in the early stages of word recognition? Syllable‐morpheme information was manipulated in the early stage of word naming by means of the fast priming paradigm. The letters in the prime were printed in a mixture of lower‐ and upper‐case letters. The change from lower to upper case occurred either at a syllable‐morpheme boundary, before the boundary, or after it (e.g., reTAKE, rETAKE, or retAKE) creating either an intact pair or a broken one. The target was always in lower case (e.g., retake). The results of Experiments 1 and 2 revealed that intact syllable and morpheme information facilitated word naming at a short Stimulus Onset Asynchrony (below awareness) but not at a long SOA, suggesting that the use of such information is automatic. A second set of experiments attempted to determine if syllable information alone could facilitate word processing. In Experiments 3 and 4, monomorphemic words were divided either at, before, or after the syllable boundary (e.g., rePEL, rEPEL, or repEL). The primes were all pseudomorphemic in the sense that the initial syllables could appear as a morpheme in other words (e.g., restate) but were not morphemic in the target words (e.g., repel). The second syllable was neither morphemic nor pseudomorphemic. Using the same SOAs as in Experiments 1 and 2, intact syllables were found to be facilitative at the short SOA, but not at the long SOA. Thus, the syllable plays a role in an early stage of word recognition. Whether morphemes that are not syllables are facilitative is still to be determined in this paradigm. 相似文献

Two groups of high and low vivid imagers heard an audiotape of a crime, read an account of it with both correct and new information, then took recognition and source memory tests. While listening and reading, both groups were told to attend carefully, but one was also instructed to form visual images of the scene. Recognition memory accuracy was greater for material from the text only than from the audio only, whereas source memory accuracy was greater for audio than for text. For source memory of text, high imagers performed more poorly than low imagers under imagery instructions. These results replicate previous work and extend it from an initial film source to an audio source. Copyright © 2002 John Wiley & Sons, Ltd. 相似文献
