“Are False Memories Permanent?”: An Investigation of the Long-Term Effects of Source Misattributions
With growing concerns over children's suggestibility and how it may impact their reliability as witnesses, there is increasing interest in determining the long-term effects of induced memories. The goal of the present research was to learn whether source misattributions found by Ceci, Huffman, Smith, and Loftus (1994) caused permanent memory alterations in the subjects tested. When 22 children from the original study were reinterviewed 2 years later, they recalled 77% of all true events. However, they only consented to 13% of all false events, compared to the 22% false consent rate (among the same subset of children) found by Ceci et al. (1994). Additionally, while children remained accurate in their recall of true events (they maintained assents 78% of the time), they “recanted” their earlier false consents 77% of the time, after the 2-year delay. Implications of these findings for child witnesses and the legal system are discussed. 相似文献

In his bookMind and body(1873), Bain set out an account in which he related the processes of associative memory to the distribution of activity in neural groupings—or neural networks as they are now termed. In the course of this account, Bain anticipated certain aspects of connectionist ideas that are normally attributed to 20th-century authors—most notably Hebb (1949). In this paper we reproduce Bain's arguments relating neural activity to the workings of associative memory which include an early version of the principles enshrined in Hebb's neurophysiological postulate. Nonetheless, despite their prescience, these specific contributions to the connectionist case have been almost entirely ignored. Eventually, Bain came to doubt the practicality of his own arguments and, in so doing, he seems to have ensured that his ideas concerning neural groupings exerted little or no influence on the subsequent course of theorizing in this area. 相似文献

This study evaluated the effectiveness of high-probability requests and time-out as treatments for noncompliance that appeared to be maintained by contingent attention in 2 developmental normal children. The introduction of high-probability requests increased compliance for 1 child but not the other. Time-out was effective with both children, and improvements in compliance were maintained at an 8-week follow-up. 相似文献

The study compared the effect of five persuasive appeals used in AIDS PSAs and condom commercials (fear arousal-no sex/condom theme; fear arousal-sex/condom theme; erotic; humorous; factual) on 122 male and 114 female college students' i]ntentions to use and taking of condoms. Results showed that the two fear appeals were more effective than other appeals in increasing intentions to use condoms with a new partner. The fear appeal–no sex/condom theme was more effective than other appeals for increasing intentions to use condoms with a steady partner. Compared to men, women rated commercials as more effective for increasing intentions to use condoms with a new partner. Persuasive appeals had no effect on the taking of free condoms. The best predictor of commercial effectiveness was the degree to which a commercial evoked a high fear of AIDS. Other significant predictors were subjects' a]ttitude toward condom use and commercial qualities of being humorous, romantic, credible, and factual. Implications are that all five types of appeals are potentially effective for use in AIDS PSAs. Recommendations include combining appeals (e.g. fear with erotic) and emphasizing the positive features of condom use. 相似文献

In general, seventeenth-century philosophers seem to have assumed that intentionality is an essential characteristic of our mental life. Malebranche is perhaps the only philosopher in the period who stands out clearly against the prevailing orthodoxy; he is committed to the thesis that there is a large class of mental items - sensations - which have no representational content. In this paper I argue that due attention to this fact makes it possible to mount at least a partial defence of his notorious doctrine of ‘the rainbow-coloured soul’; Malebranche's doctrine is a striking anticipation of modern adverbial theories of sensation. I then argue that failure to appreciate the non-intentional character of sensations for Malebranche vitiates one recent attempt to explain why he accepted the Cartesian doctrine of the beastmachine; in contrast to the Radners, I suggest that Malebranche has the philosophical resources to offer an interesting theory of animal consciousness, and that his failure to develop such a theory rests largely on his acceptance of certain theological arguments. The paper ends by speculating about how Malebranche's theological commitments may have encouraged him to adopt the philosophically important thesis that intentionality is not the mark of the mental. 相似文献

Abstract— Many of the decisions that people must make involve selections from arrays of identical options The studies presented explored people's preferences in two contexts choosing one Item from rows of identical items and choosing a route from a series of identical routes The first three studies examined preferences for items in particular positions Whether people were choosing a product from a grocery shelf, deciding which bathroom stall to use, or marking a box on a questionnaire, they avoided the ends and tended to make their selection from the middle For example, when there were four rows of a product in the supermarket, only 29% of the purchases were from the first and last rows, and 71% were from the middle two The last three studies examined whether a similar preference exists in picking a route when all of the available routes are the same length and require same number of turns In solving mazes, planning routes on maps, and walking around campus, people showed the pattern opposite to that found for choosing Items in rows They avoided the middle routes and tended to take either the first or the last one Overall, the last available route was the favorite The notion that these behaviors may minimize mental effort is explored 相似文献

This paper describes a pilot follow-up study of a behavioral program for 20 young people with learning disabilities and challenging behavior. Eighteen participants made good overall improvement during the treatment period, and this was partially maintained at follow-up. Eight had continued to improve, eight had deteriorated slightly and four had deteriorated markedly. Adaptive skills were generally maintained. The reemergence of challenging behaviors explained the difference between the Good and Poor Outcome groups. Those participants in the Good Outcome group were younger on admission, scored lower on adaptive skills and higher on challenging behaviors. In addition they had remained on the treatment programme for 12–18 months and had been discharged from the Unit for longer. The overall level of independent living had increased from preadmission and the majority of participants were living in less restrictive placements. These results confirm and extend the findings of previous research. The paper concludes by highlighting the need for more detailed longitudinal follow-up studies in this area. 相似文献

Although the Rescorla-Wagner model is widely taught in learning courses, most textbooks present a simplified version that does not contain all of its parameters. On the basis of Rescorla and Wagner 1972) and the Turbo PASCAL program by Lachnit, Schneider, Lipp, and Kimme! (1988), we created a simulation using STELLA-II, an icon-based program by High Performance Systems, Inc. We argue that this simulation facilitates teaching the complete Rescorla-Wagner model. Using trans-switching (Kimmel & Ray, 1978; Lachnit, 1986; Murrin & Kimmel, 1986) as an example, we demonstrate the effectiveness of the STELLA-II version of the Rescorla-Wagner model as a heuristic tool. 相似文献
