This paper provides the first demonstration that people can learn about the positive and negative value of other people (e.g., neutral faces) under minimal learning conditions, with stable individual differences in this learning. In four studies, participants viewed neutral faces paired with sentences describing positive, negative or neutral behaviors on either two (Study 1) or four (Studies 2, 3, and 4) occasions. Participants were later asked to judge the valence of the faces alone. Studies 1 and 2 demonstrated that learning does occur under minimal conditions. Study 3 and 4 further demonstrated that the degree of learning was moderated by Extraversion. Finally, Study 4 demonstrated that initial learning persisted over a period of 2 days. Implications for affective processing and person perception are discussed. 相似文献

A function, written in R, for testing whether the distribution of responses in one condition can be considered a combination of the distributions from two other conditions is described. The important aspect of this function is that it does not make any assumptions about the shape of the distributions. It is based o nthe Kolmogorov-Smirnov D statistic. The function also allows the user to test more specific and, hence, more statistically powerful hypotheses. One hypothesis, that the mixture does not capture the middle third of the distribution, is included as a built-in option, and code is provided so that other alternatives can easily be run. A power analysis reveals that the function is most likely to detect a difference between the combined conditions' distribution and the other distribution when the center of the other distribution is near the midpoint of the two original distributions. Critical p values are estimated for each set of distributions, using bootstrap methods. An example from human memory research, exploring the blending hypothesis of the misinformation effect, is used for illustrative purposes. 相似文献

The present investigation combined a classical conditioning paradigm with a head–shake response (HSR) habituation task in order to evaluate the importance of dorsal hippocampal neural plasticity to spontaneous recovery. In the first experiment animals exhibited rapid HSR habituation (air stimulus to the ear) and an 85% level of spontaneous recovery following a 24 h inter-session interval. The addition of a brief tone prior to the air stimulus produced a similar pattern of habituation during the first session, but the level of spontaneous recovery was reduced (44%) during Session II. In a second experiment dorsal hippocampal lesioned rats placed on this tone/HSR paradigm responded with an 87% level of spontaneous recovery during Session II; while neocortex lesioned control rats indicated significantly reduced levels of spontaneous recovery (55%). In a third experiment bilateral injections of a general MMP inhibitor, FN-439, into the dorsal hippocampus resulted in high levels of spontaneous recovery (81%); while control rats injected with artificial cerebrospinal fluid displayed a significant attenuation of spontaneous recovery (45%). Finally, animals bilaterally injected with a specific MMP-3 inhibitor into the dorsal hippocampus indicated very similar results to those obtained following FN-439 injection. These findings indicate that animals prepared with dorsal hippocampal lesions, or injections with an MMP inhibitor, revealed an impaired association between the tone and air stimulus thus maximum spontaneous recovery was present 24 h later. Thus, it appears that the dorsal hippocampus influences habituation by conserving responses and reducing spontaneous recovery when a temporally contingent signaling cue is present. 相似文献

This research examined whether an Enhanced Cognitive Interview (ECI) and a Modified Cognitive Interview (MCI) improved 75- to 96-year-old adults' recall for a video-taped event. Specifically, we examined the effectiveness of these interviews in relation to a Structured Interview (control), and compared the performance of older adults who scored high or low on the Mini-Mental State Examination (MMSE), which is a test to assess cognitive functioning. Participants with low MMSE scores recalled fewer correct details, and were less accurate than those with high scores. Nevertheless, both high and low MMSE groups reported substantially more correct information about Action, Person, Object, and Surrounding details with the MCI and ECI than with the SI. No corresponding increase in the amount of incorrect and confabulated information was found. Furthermore, recall accuracy for both groups was greater with the ECI and MCI than with the Structured Interview. Overall, findings suggest that older individuals, including those with reduced cognitive ability can benefit from the use of Cognitive Interview protocols. 相似文献

This study examined different methods of combining data from a well established rating scale – the Disruptive Behavior Disorders
Rating Scale (DBDRS) – with data from a well established interview – the computerized self report version of the Diagnostic
Interview Schedule for Children for DSM-IV (P-DISC-IV) – when examining parent report of ADHD. These measures were completed
for 80 children who participated in a summer camp for children with disruptive behavior. Results showed significant overlap
between the two diagnostic measures but parent report on the DBDRS was more highly associated with children’s camp behaviors
than was parent report on the P-DISC-IV. In addition, combining ratings and interview data using an “either/or” rule was more
highly associated with camp behavior than was combining data using a “both/and” rule. Results suggest there may be little
additional value of adding data from parent self-report on the computerized version of the P-DISC-IV to behavior rating data. 相似文献

Age differences in emotion recognition from lexical stimuli and facial expressions were examined in a cross-sectional sample of adults aged 18 to 85 (N = 357). Emotion-specific response biases differed by age: Older adults were disproportionately more likely to incorrectly label lexical stimuli as happiness, sadness, and surprise and to incorrectly label facial stimuli as disgust and fear. After these biases were controlled, findings suggested that older adults were less accurate at identifying emotions than were young adults, but the pattern differed across emotions and task types. The lexical task showed stronger age differences than the facial task, and for lexical stimuli, age groups differed in accuracy for all emotional states except fear. For facial stimuli, in contrast, age groups differed only in accuracy for anger, disgust, fear, and happiness. Implications for age-related changes in different types of emotional processing are discussed. 相似文献

Two studies examined whether a Cognitive Interview improves older witnesses' recall. Study 1 compared the quality and quantity of older adults' recall when given a typical UK police interview, the Enhanced Cognitive Interview (ECI), or a modified version of the Cognitive Interview (MCI). The MCI was identical to the ECI except that the change perspective technique was omitted. Old–old (75–95‐years) adults' recall was less complete and less accurate than that of young–old (60–74‐years) adults, which was less complete and accurate than that of young (17–31‐years) adults. The ECI and MCI increased the number of correct Person, Action, Object and Surrounding details reported across every age group, without increasing the number of incorrect or confabulated details recalled. In Study 2, it was found that these effects remained when interviews were re‐scored using a system that reflected police officers' decisions about the investigative relevance of details.
