Initial evidence suggests that suppressing a thought prior to sleep results in subsequent dreaming of that thought. The present research examined the influence of cognitive load on dreaming following suppression. In Experiment 1, 100 participants received either a suppression instruction or no instruction for an intrusive thought prior to sleep, and subsequently completed a dream diary. Participants instructed to suppress reported dreaming about the target thought more than controls; dream rebound was predicted by poorer performance on a working memory task. In Experiment 2, 126 participants received either a suppression instruction or no instruction for an intrusive thought prior to sleep, and half of participants also had cognitive load of learning a 9-digit number. Participants receiving the suppression instruction under cognitive load reported greater dream rebound than other participants. These findings indicate that thought suppression prior to sleep leads to dream rebound, and this effect is enhanced by cognitive load. 相似文献

Research with humans and with nonhuman species has suggested a special role of room geometry in spatial memory functioning. In two experiments, participants learned the configuration of a room with four corners, along with the configuration of four objects within the room, while standing in a fixed position at the room's periphery. The configurations were either rectangular (Experiment 1) or irregular (Experiment 2). Room geometry was not recalled better than object layout geometry, and memories for both configurations were orientation dependent. These results suggest that room geometry and object layout geometry are represented similarly in human memory, at least in situations that promote long-term learning of object locations. There were also some differences between corners and objects in orientation dependence, suggesting that the two sources of information are represented in similar but separate spatial reference systems.

An evaluation method called the Signal Evaluation Environment (SEE) was developed for use in the early stages of the design
process of peripheral warning signals while driving. Accident analyses have shown that with complex driving situations such
as intersections, the visual scan strategies of the driver contribute to overlooking other road users who have the right of
way. Salient peripheral warning signals could disrupt these strategies and direct drivers’ attention towards these road users.
To select effective warning signals, the SEE was developed as a laboratory task requiring visual–cognitive processes similar
to those used at intersections. For validation of the SEE, four experiments were conducted using different stimulus characteristics
(size, colour contrast, shape, flashing) that influence peripheral vision. The results confirm that the SEE is able to differentiate
between the selected stimulus characteristics. The SEE is a useful initial tool for designing peripheral signals, allowing
quick and efficient preselection of beneficial signals. 相似文献

Recently, several authors claimed that the curvilinear shape of rating-based source memory receiver operating characteristics (ROCs) refutes threshold models. However, rating-based ROCs are not diagnostic to disprove threshold models. Furthermore, source memory ROC-analyses ignore influences of other processes like old-new-detection and old-new-response-tendencies, so direct estimation of parameters is preferable. Five source monitoring experiments with different response bias manipulations and materials were conducted. We fitted the Two High Threshold Multinomial Model of Source Monitoring by Bayen, Murnane, and Erdfelder (1996) and the Multivariate Signal Detection Model for Selection DeCarlo (2003). We also included rating-based ROCs. The results suggest that both models are at least equally valid as measurement tools which capture bias processes in the corresponding parameters, and they can perhaps be integrated theoretically. 相似文献

This study examined positive self-perceptions in relation to depressive symptoms and attributional style in a sample of 88 boys with attention-deficit/hyperactivity disorder (ADHD) assessed at baseline and at a 2- to 3-year follow-up. Change in boys' self-perceptions of competency in the scholastic, social, and behavioral domains was examined as a predictor of changes in depressive symptoms and depressive attributional style. Additionally, teacher-rated perceptions of competency at baseline and follow-up were considered as unique predictors. Results indicated that across all three domains, a reduction in children's self-perceptions of competency over time predicted greater depressive symptoms at follow-up, even when controlling for teacher-rated competency. Analyses also suggested that a reduction in self-perceptions in the social domain was the strongest relative predictor of later depressive symptoms and also predicted greater depressive attributional style at follow-up. In contrast, teacher-rated competency was not a significant predictor of depressive symptoms or attributional style at follow-up. Results support a protective function of positive self-perceptions in regards to depressive cognitions over a 2- to 3-year period for children with ADHD. However, literature suggesting risks for other negative outcomes also is discussed. 相似文献

Clinical and population-based samples show high comorbidity between Substance Use Disorders (SUDs) and Axis II Personality Disorders (PDs). However, Axis II disorders are frequently comorbid with each other, and existing research has generally failed to distinguish the extent to which SUD/PD comorbidity is general or specific with respect to both specific types of PDs and specific types of SUDs. We sought to determine whether ostensibly specific comorbid substance dependence-Axis II diagnoses (e.g., alcohol use dependence and borderline personality disorder) are reflective of more pervasive or general personality pathology or whether the comorbidity is specific to individual PDs. Face-to-face interview data from Wave 1 and Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions were analyzed. Participants included 34,653 adults living in households in the United States. We used hierarchical factor models to statistically partition general and specific personality disorder dimensions while simultaneously testing for specific PD-substance dependence relations. Results indicated that substance dependence-Axis II comorbidity is characterized by general (pervasive) pathology and by Cluster B PD pathology over and above the relationship to the general PD factor. Further, these relations between PD factors and substance dependence diagnoses appeared to largely account for the comorbidity among substance dependence diagnoses in the younger but not older participants. Our findings suggest that a failure to consider the general PD factor, which we interpret as reflecting interpersonal dysfunction, can lead to potential mischaracterizations of the nature of certain PD and SUD comorbidities. 相似文献

Previous research has shown that incongruence between implicit and explicit achievement motives impairs flow experience. We
examined this relationship in a more differentiated manner by arguing that achievement-motive incongruence only exerts negative
effects when individuals act in situations in which achievement incentives are present and arouse conflict between the two
motives. In non-achievement situations, no negative effects of achievement-motive incongruence on flow experience are expected.
Study 1 and Study 2 showed that participants with incongruent implicit and explicit achievement motives reported less flow
in achievement- as compared to non-achievement-oriented sport situations. In Study 3, we experimentally manipulated achievement
and non-achievement situations. Again, motive incongruence impaired the experience of flow in achievement but not in non-achievement
situations. 相似文献

The aim of this work was to examine the psychometric properties of the Spanish version of the "Recovery Experience Questionnaire" developed by Sonnentag and Fritz. The sample was made up of 941 professionals from the security sector. Results from the exploratory factor analysis suggested the possibility of considering a four-factor structure. Confirmatory factor analysis showed that the four-factor model with three correlated items each provided the best fit to the data (CFI=0.97, GFI=0.96, NNFI=0.96, RMSEA=0.05 y AIC=171.76). Therefore, the questionnaire maintains the four recovery experiences -psychological detachment from work, relaxation, mastery experiences and control over leisure time--but with 12 items instead of 16 items as in the original scale. Reliability analysis showed good internal consistency for this scale with Cronbach alpha coefficients for the factors ranging from .75 to .88. Significant correlations were found between the recovery experiences and various external variables, providing evidence of construct validity. Thus, this Spanish version shows adequate psychometric properties and may help to achieve a better understanding of this topic. 相似文献

The present research aims to explain women’s endorsement of hostile and benevolent sexist beliefs. Based on a convenience sample of N?=?92 women in the general public in Germany, Study 1 demonstrated that women endorse hostile sexist beliefs when they do not think about themselves when completing the hostile sexism scale but about non-traditional female subtypes (feminists or career women). In contrast, women were more likely to agree with benevolent sexist beliefs the more they internalize these beliefs and the more they think about traditional subtypes (housewives) while completing the scale. A follow-up experimental study using a convenience sample of N?=?123 German women further demonstrated that these results depend on women’s identification with the respective subtypes. 相似文献

This paper comments on the Langhinrichsen-Rohling article (2010), which reviews five major controversies present in the field of partner violence research and in which the author describes a new typology of mutually-violent couples. Strengths of the original article are discussed, including the author’s incorporation of existing data into a new typology, her focus on context in examining relationship violence, and her reasoned argument for studying the behavior of both male and female aggressors. Limitations associated with the scope and explicit predictions of Langhinrichsen-Rohling’s new typology are also covered in this commentary. Finally, the need for improved treatments for partner violence is discussed. 相似文献
