Previous work on human memory has shown that prompting participants with false events and self-relevant information via different types of media such as narratives, edited 2-dimensional images, and mental imagery creates false memories. This study tested a new form of media for studying false memory formation: Immersive Virtual Environment Technology (IVET). Using this tool, we examined how memory was affected by viewing dynamic simulations of avatars performing novel actions. In the study, 55 preschool and elementary children were randomly assigned to 1 of 4 memory prompt conditions (idle, mental imagery, IVET simulation of another child, or IVET simulation of self). Each child was questioned 3 different times: once before the memory prompt, once immediately after the memory prompt, and once approximately 5 days after the memory prompt. Results showed that preschool children were equally likely to develop false memories regardless of memory prompt condition. But, for elementary children, the mental imagery and IVET self conditions caused significantly more false memories than the idle condition. Implications regarding the use of digital media in courtroom settings, clinical therapy settings, entertainment, and other applications are discussed.  相似文献

Relations between adult attachment and memory for earlier emotional reactions to negative and positive events were examined. Hypotheses were that avoidance would be associated with underestimating earlier negative affect, whereas anxiety would be associated with overestimating earlier negative affect. Also, both avoidance and anxiety were expected to relate to underestimating earlier positive affect intensity. Participants (119 college students) completed daily report forms three times a day for 4 days on which they described and rated their immediate emotional reactions to events within each time period. Approximately 10 days later, they were asked to estimate their immediate emotional reaction to one negative event and one positive event. Events were coded as interpersonal or non-interpersonal. Contrary to hypotheses, for those lower on avoidance, anxiety related to lower levels of recalled negative affect (i.e., greater underestimation) for negative interpersonal events. As expected, with positive events, anxiety and avoidance related to lower levels of recalled positive emotions. Results suggest that memory processes could be one explanation of how working models operate and are sustained over time.  相似文献

Abstract

The smoking status of 239 physicians was obtained from a mail survey in 1981. MMPI data, which had been obtained from these men 25 years earlier, was used to prospectively predict smoking status at follow-up. Those who never smoked had scores indicative of social conventionality (low scores on L, Pd, and Schubert scales; high scores on Ego-control). A similar pattern was found among smokers who quit after a relatively short smoking history. Compared to ex-smokers, those who continued to smoke at the time of follow-up were characterized by high scores on the Pd and Ma scales. These results were discussed in terms of a multi-stage conceptualization of the smoking cessation process.  相似文献

To test whether activity-based anorexia (ABA) still occurs after preadaptation to the feeding schedule, 20 rats were first exposed to a feeding schedule of one 90-min meal per day until adaptation occurred (measured by maintenance of stable body weight). Then, during ABA training, half the rats (wheel group) were confined in running wheels except during the daily meal, and half (cage group) were not. Wheel running suppressed feeding—that is, food intake in the wheel group was less than that in the cage group. Also, the rats in the wheel group lost weight, whereas those in the cage group did not. Wheel running increased over days. Thus, the defining characteristics of ABA were evident in rats that were not subjected to ABA training until after they had become well adapted to the feeding schedule. These findings support the view that the suppression of feeding produced by wheel running triggers the vicious circle of ABA. They also cast doubt on the hypothesis that activity-induced interference with adaptation to the feeding schedule plays a key role in causing ABA.  相似文献

In two studies, we examined inter-individual variability in responses to both negative and positive events. In the first study, participants (119 college students) reported on negative and positive events from their own lives. The second was an experiment in which participants (133 college students) were given either negative or positive feedback about their personality. With negative events, more insecure individuals, especially anxiously attached, evidenced more intense negative emotional reactions and greater processing of (i.e., ruminating on) negative experiences. With positive events, securely attached individuals and less anxiously attached engaged in greater processing of positive experiences (maximized), whereas more insecure individuals tended to minimize positive experiences. Gender differences for emotion regulation were moderated by either attachment or event type. Findings for negative events generally coincide with prior research, and those for positive events provide new evidence that attachment style could affect how people react to positive events and emotions.  相似文献

Previous research has identified twenty-six factors that may affect pregnancy management decisions following prenatal diagnosis of DS; however, there is no consensus about the relative importance or effects of these factors. In order to better understand patient decision-making, we conducted expansive cognitive interviews with nine former patients who received a prenatal diagnosis of DS. Our results suggest that patients attached unique meanings to factors influencing decision-making regardless of the pregnancy outcome. Nineteen of the twenty-six factors previously studied and four novel factors (rationale for testing, information quality, pregnancy experience, and perception of parenting abilities and goals) were found to be important to decision-making. We argue that qualitative studies can help characterize the complexity of decision-making following prenatal diagnosis of DS.  相似文献

This study examined an activity restriction/pleasurable activities mismatch model for psychosocial and health-related outcomes. A total of 108 spousal caregivers of patients with Alzheimer's Disease (AD) were assessed for their experience of social and recreational activities over the past month as well as their perception of how restricted they were for engaging in social and recreational activities. Participants were divided into three groups based on their reported activities and activity restriction: HPLR = High Pleasant Events + Low Activity Restriction (i.e., reference group; N = 28); HPHR/LPLR = Either High Pleasant Events + High Activity Restriction or Low Pleasant Events + Low Activity Restriction (N = 43); LPHR = Low Pleasant Events + High Activity Restriction (N = 37). We hypothesized that participants reporting low pleasant events combined with high activity restriction (LPHR) would demonstrate greater disturbance relative to other two groups in multiple outcome domains, including: (a) greater mood disturbance, (b) greater use of negative coping factors, (c) reduced use of positive coping strategies, (d) reduced report of psychological resource factors (e.g., personal mastery, self-efficacy), and (e) increased report of subjective health difficulties (e.g., sleep disturbance). Results generally supported our hypotheses, suggesting that assessment of both constructs is important for best predicting quality of well-being in AD caregivers, and potentially for establishing maximal effect in behavior therapy for caregivers.  相似文献

Although attentional control and memory change considerably across the life span, no research has examined how the ability to strategically remember important information (i.e., value-directed remembering) changes from childhood to old age. The present study examined this in different age groups across the life span (N = 320, 5-96 years old). A selectivity task was used in which participants were asked to study and recall items worth different point values in order to maximize their point score. This procedure allowed for measures of memory quantity/capacity (number of words recalled) and memory efficiency/selectivity (the recall of high-value items relative to low-value items). Age-related differences were found for memory capacity, as young adults recalled more words than the other groups. However, in terms of selectivity, younger and older adults were more selective than adolescents and children. The dissociation between these measures across the life span illustrates important age-related differences in terms of memory capacity and the ability to selectively remember high-value information.  相似文献

This study examined the association between childhood ADHD and juvenile delinquency by examining data from the Pittsburgh ADHD Longitudinal Study (PALS), a follow-up study of individuals diagnosed with ADHD in childhood (ages 5–12) and recontacted in adolescence and young adulthood for yearly follow-up (age at first follow-up interview M = 17.26, SD = 3.17). Participants were 288 males with childhood ADHD and 209 demographically similar males without ADHD who were recruited into the follow-up study. Delinquency information gathered yearly during the second through eighth follow-up provided a comprehensive history of juvenile delinquency for all participants. Four childhood diagnostic groups [ADHD-only (N = 47), ADHD + ODD (N = 135), ADHD + CD (N = 106), and comparison (N = 209)] were used to examine group differences on delinquency outcomes. Analyses were conducted across three dimensions of delinquency (i.e., severity, age of initiation, and variety). Individuals with childhood ADHD + CD displayed significantly worse delinquency outcomes than the other three groups, across almost all indices of offending. When compared to comparison participants, boys with ADHD-only and ADHD + ODD in childhood displayed earlier ages of delinquency initiation, a greater variety of offending, and higher prevalence of severe delinquency. These findings suggest that although childhood ADHD + CD creates the greatest risk for delinquency, boys with ADHD-only and ADHD + ODD also appear at a higher risk for later offending. The patterns of offending that emerged from the PALS are discussed in the context of the relationship between ADHD, comorbidity, and delinquency.  相似文献

It is well established that height influences the perceived character of men but very little evidence exists that the same influences of height exist for women. To investigate the effects of female height on perception of their character, we used a novel technique of digitally altering the perceived height of two women depicted in photographs such that the same targets appeared to be of tall or short stature to different participants. We asked participants to rate each of the two women on personal qualities and characteristics that reflected the instrumental/expressive distinction in masculine/feminine stereotypes. Overall, tall women were rated as more intelligent, affluent, assertive and ambitious than shorter women. A perceiver-sex difference was found such that men rated short females more highly than tall females on expressive characteristics while women raters did not. Thus, we provide the first direct evidence that female height influences perception of their character.  相似文献
