Individuals are not always aware of their mental content. We tested whether lack of awareness occurs in those who have experienced trauma, with and without posttraumatic stress disorder (PTSD). We also examined the role of proposed cognitive mechanisms (working memory and inhibition) in explaining unnoticed intrusions. Individuals with PTSD (n = 44), and varying levels of symptoms (high posttraumatic stress [PTS]: n = 24; low PTS: n = 37) reported on intrusive thoughts throughout a reading task. Intermittently, participants responded to probes about whether their thoughts were trauma related. Participants were “caught” engaging in unreported trauma-related thoughts (unnoticed intrusions) for between 24 and 27% of the probes in the PTSD and high PTS groups, compared with 15% of occasions in the low PTS group. For trauma-related intrusions only, participants lacked meta-awareness for almost 40% of probes in the PTSD group, which was significantly less than that observed in the other groups (~60%). Contrary to predictions, working memory and response inhibition did not predict unnoticed intrusions. The results suggest that individuals who have experienced significant trauma can lack awareness about the frequency of their trauma-related thoughts. Further research is warranted to identify the mechanisms underpinning the occurrence of unnoticed intrusions. 相似文献

In the past 10 years, the field of relationship science—like many other fields—has been exposed to dramatic changes in how scientists approach the research process. Relationship science has been at the forefront of many recent changes in the field, whether it be high profile replication attempts or broader discussions about how to increase rigor and reproducibility. A major goal of this special issue was to provide an opportunity for relationship scientists to engage with these issues and reforms. The first four articles in this special issue represent a sampling of different approaches relationship researchers have used to enhance the credibility of their work. 相似文献

This research examines how arousal enhances consumer tendencies to be influenced by the majority when decision making, also known as “herding.” Physiological arousal was manipulated in three controlled experiments, using discrete choice decisions as the dependent variable. The results suggest that arousal enhances tendencies to choose more popular options and that deindividuation mediates the effect of arousal on choice. This research enriches our understanding of the theoretical relationship between arousal and consumer decision making, by suggesting that arousal increases herding. The practical relevance of our findings suggests that strategies to increase herding effects, such as “popular choice” stickers and social media metrics, may be enhanced by making the experience more arousing. 相似文献

This article addressesthree questions about personality development in a 30‐year longitudinal study of women (N = 78): (1) To what extent did the women maintain the same position inrelation to each other on personality characteristics over the 30 years, and what broad factorswere related to the amount of change in their rank order? (2) Did the sample as a whole increaseor decrease over time on indices of personality growth, and did they change in ways distinctive towomen? (3) Were experiential factors associated with individual differences in the amount ofchange? Results showed that personality was quite consistent while also showing that timeinterval was positively related to rank‐order change and age was negatively related to rank‐orderchange. Over the period from age 21 to age 52, the women increased on measures ofnorm‐orientation and complexity and showed changes on measures of Dominance andFemininity/Masculinity consistent with the hypothesis that changing sex roles would lead toincreases in Dominance and increases, then decreases, in Femininity/Masculinity. A third set ofresults showed that changes in Dominance and Femininity/Masculinity were associated with lifecircumstances such as marital tension, divorce, and participation in the paid labor force. Theimplications of the findings for personality development and growth are discussed. 相似文献

This is a follow up study of Barbuto's 2000 work in which leaders' ratings and targets' self-reported resistance to task assignments are compared. Scores on the Anticipated Resistance Indicator among 650 leader-member dyads measure resistance based on Barbuto's 1997 five concentric zones of Preference, Indifference, Legitimate, Influence, and Noninfluence, examined from both leaders' and targets' perspectives. Responses indicated that leaders tend to underestimate followers' willingness to perform assigned tasks. In addition, leaders tend to overestimate targets' unwillingness to perform undesirable, less enjoyable tasks. 相似文献

Differences in the timbre of sounds in a sequence can affect their perceptual organization. Using a performance measure, Hartmann and Johnson (1991) concluded that streaming could be predicted primarily by the extent to which sounds were passed by different peripheral channels. However, results from a rating task by Dannenbring and Bregman (1976) suggested that sounds in the same spectral region (passed by the same peripheral channels) can be allocated to different streams. In Experiment 1, it was found, using an interleaved melody task, that target sounds could be selected from distractors in the same spectral region more easily when they differed in timbre. This finding might result from primitive stream segregation or schema-driven selection, but not from peripheral channeling. In Experiment 2, a rhythm discrimination task was used, requiring the sounds to be integrated for good performance. Differences in timbre impaired performance, indicating the occurrence of primitive stream segregation. 相似文献

The present study used meta-analytic techniques to test whether trait consistency maximizes and stabilizes at a specific period in the life course. From 152 longitudinal studies, 3,217 test-retest correlation coefficients were compiled. Meta-analytic estimates of mean population test-retest correlation coefficients showed that trait consistency increased from .31 in childhood to .54 during the college years, to .64 at age 30, and then reached a plateau around .74 between ages 50 and 70 when time interval was held constant at 6.7 years. Analysis of moderators of consistency showed that the longitudinal time interval had a negative relation to trait consistency and that temperament dimensions were less consistent than adult personality traits. 相似文献

Three experiments are reported in which the strategy usage for a compass point directions task was investigated. For this task, people may use either an efficient cancellation strategy or an inefficient spatial strategy (see Roberts, Gilmore, & Wood, 1997). Experiment 1, together with Experiment 2, showed that users of cancellation are unlikely to have explicit prior knowledge of this strategy; instead they discover it as a result of experience with the task. Experiment 1 also showed that strategy selection is unlikely to be based on stylistic preferences, and that reducing the cognitive demands of the task does not increase the discovery of cancellation. Experiment 3 showed that evaluation of strategy validity is also of importance: Unsuccessful evaluation may prevent the selection of a newly discovered strategy, even if it is the more efficient method. 相似文献

In each of 3 experiments, different sets of 4 pigeons (Columba livia) were trained to discriminate between 2 visual symbols that covered wells containing food items that varied in number, mass, or both. In Experiment 1, the symbols were associated with 0, 1, 3, 5, 7, or 9 pieces of grain reward. The pigeons learned to choose the symbol corresponding to the larger reward, and on summation tests, they chose the pair of symbols that summed to the larger total reward. When number of food pellets was varied but mass of reward was held constant in Experiment 2, preference for the larger number symbols failed to appear. When number was held constant and mass was varied in Experiment 3, the pigeons showed a clear preference for the larger mass symbols on single-symbol and summation tests. These findings show that pigeons summate the value of symbols and are more likely to represent symbols by mass of food reward than by number of food items. 相似文献
