Mental time travel (MTT) is the ability to mentally project oneself into one’s personal past or future, in terms of memories of past events or projections of possible future events. We investigated the frequency and valence of involuntary (spontaneously arising) MTT in the context of high trait worry. High (N = 18) and low (N = 16) worriers recorded the frequency and valence of involuntary memories and future projections using a structured notebook and completed measures probing individual differences related to negative affectivity. Involuntary future projections were as frequent as involuntary memories. We found a positivity bias for both past and future MTT, in that fewer negative events were reported than positive or neutral ones. This positivity bias was greater for future than for past events. Individual differences related to negative affectivity were positively associated with the proportion of negative events, indicating a reduced positivity bias in individuals with a general tendency to experience negative affect.  相似文献

In this study we examine whether components of spiritual transcendence can explain individual differences in mental health in a Hungarian adult sample (N = 583), with a special focus on the associations in two subsamples, religious professionals and psychotherapists. Using the Spiritual Transcendence Scale (STS), we found that religious professionals presented higher Prayer Fulfillment and Universality than psychotherapists; however, members of both professional groups scored higher than other professionals on these dimensions. By contrast, psychotherapists were superior to religious professionals in Connectedness. Moreover, higher Universality predicted better mental health, even after controlling for gender, age, profession, and basic personality traits. No interaction effects were found between profession and the subscales of the STS. Results suggest that the potential mental health benefits of spirituality, especially in form of a universal view of existence, are equally present in both specific professions and in the general sample, whereas the professions themselves still reflect differences both in spirituality and in well-being.  相似文献

Abstract

The present study examined the relationship between feelings provoked by child sexual abuse (CSA) and posttraumatic stress disorder (PTSD) symptom scores in a sample of 163 female survivors of CSA. Finkelhor and Browne's traumagenic dynamics model was applied. The interactive effects of provoked feelings with perpetrator age and the existence of abuse disclosure were also studied. Results showed an overall relationship between feelings provoked by CSA and PTSD symptom scores. Feelings of stigma, betrayal, and powerlessness as a result of CSA were associated with PTSD symptom score when the entire group of CSA victims was analyzed. The role of traumatic sexualization was relevant only when analyzed in interaction with the age of the perpetrator and disclosure. The relationship between traumatic sexualization and PTSD symptom scores was only significant when the abuse was committed by an adult perpetrator and when a disclosure was made during the time of abuse, or a short time after the abuse had occurred.  相似文献

The Icelandic version of the Anxiety Sensitivity Index was investigated in two studies of college students. A principal components analysis of ASI scores from both studies (N=718) yielded three components similar to what has been found previously: Psychological Concerns, Physical Concerns and Social Concerns. In the first study the relationship between the ASI and trait anxiety was investigated. It was analysed at the level of the total scales but also at the level of subscales of both instruments. Two subscales of the STAI, measuring respectively Anxiety-trait and Depression-trait, were used as well as the Psychological Concerns and Physical Concerns subscales of the ASI. In a second study the relationships between ASI and its subscales and two symptom measures of anxiety and depression were addressed. ASI was in both studies more strongly related to the anxiety than the depression scales. Also, in both studies the Physical Concerns subscale of the ASI was more strongly related to anxiety than to depression, whereas the Psychological Concerns subscale was equally related to anxiety and depression. Taken together the studies support the notion of different relationships between different aspects of anxiety sensitivity, and anxiety and depression as traits, cognitive symptoms and mood related symptoms.  相似文献

Children’s private speech has been widely studied among children, but it is clear that adults use private speech as well. In this study, illiterate adults’ private speech during a “school-like” task was explored as a function of literacy level and task difficulty in a sample of 126 adults enrolled in a public literacy program. A main effect for literacy level was found—private speech was more internalized and less externalized among adults with higher literacy levels. Externalized private speech was more frequently observed among illiterate adults engaged in the most difficult task. Private speech served cognitive functions as indicated by the proportion of self-regulatory private speech and the proportion of private speech preceding actions being higher in the advanced literacy group and among illiterate adults doing the easier task. Internalized private speech, self-regulatory private speech, and private speech preceding action were each positively correlated with performance and negatively correlated with time to complete the task. The use of private speech in illiterate adults appears to be linked to the mastery of cultural experiences, such as literacy, similar to the self-talk of children.  相似文献

Identity development represents a central task of adolescence. Identity achievement is characterized by a coherent sense of who one is following a period of exploration and can help navigate the challenges of adulthood. This study examined identity within a quality of life (QOL) context in 85 adolescents with a renal transplant or with Type 1 diabetes in comparison to 90 healthy controls. Results revealed significant differences in ideological identity, with patients showing higher levels of diffusion and controls showing higher levels of foreclosure. No differences with respect to interpersonal identity, QOL, perceived control over the QOL domains, and perceived opportunities for growth and development were found. Future research should assess identity and QOL over a longer period of time to determine whether differences between chronically ill and healthy young adults can be detected.  相似文献

Self-harm, which consists of nonsuicidal self-injury and attempted suicide, is a public health problem that is not well understood. There is conflicting evidence on the role of gender in predicting self-harm. Abuse history also is a potentially relevant factor to explore, as it is related to both gender and self-harm. In this study, we hypothesized that abuse history, as opposed to gender, would predict self-harm. Three hundred and ninety-seven undergraduates completed a self-report survey that assessed abuse history, nonsuicidal self-injury, and attempted suicide. The results suggested that abuse history predicted nonsuicidal self-injury and attempted suicide. These findings can inform clinical interventions as they reinforce the importance of including abuse history in the conceptualizations and treatment of self-harm.  相似文献

We investigated the contribution of low-level saliency to human eye movements in complex dynamic scenes. Eye movements were recorded while naive observers viewed a heterogeneous collection of 50 video clips (46,489 frames; 4-6 subjects per clip), yielding 11,916 saccades of amplitude ≥2°. A model of bottom-up visual attention computed instantaneous saliency at the instant each saccade started and at its future endpoint location. Median model-predicted saliency was 45% the maximum saliency, a significant factor 2.03 greater than expected by chance. Motion and temporal change were stronger predictors of human saccades than colour, intensity, or orientation features, with the best predictor being the sum of all features. There was no significant correlation between model-predicted saliency and duration of fixation. A majority of saccades were directed to a minority of locations reliably marked as salient by the model, suggesting that bottom-up saliency may provide a set of candidate saccade target locations, with the final choice of which location of fixate more strongly determined top-down.  相似文献

In this paper, the links between cognitive constraints, visual behaviours, and perceptual judgements are examined. Two experiments investigated the perceptual processes employed during same-different judgement tasks. In Experiment 1, experts' eye movements (i.e., number of fixations and fixation duration) were consistent across discrepant source and target conditions where the number of displaced elements was manipulated. In contrast, novices decreased the number of fixations employed as the number of elements displaced increased. The findings are consistent with the view that both experts and novices process information in a manner (relational or attributional) that constrains the type of visual search used (low or high sensitive to attributional change). In Experiment 2, manipulation of target presentation confirmed that recognition was viewpoint dependent for both expert and novice players. The degradation in performance was accompanied by a change in the visual search behaviours employed by experts, which confirmed thr strength of the search–cognition–performance links  相似文献

In this study, we investigated the role of facial cues in cooperator and defector recognition. First, a face image database was constructed from pairs of full face portraits of target subjects taken at the moment of decision‐making in a prisoner's dilemma game (PDG) and in a preceding neutral task. Image pairs with no deficiencies (n = 67) were standardized for orientation and luminance. Then, confidence in defector and cooperator recognition was tested with image rating in a different group of lay judges (n = 62). Results indicate that (1) defectors were better recognized (58% vs. 47%), (2) they looked different from cooperators (p < .01), (3) males but not females evaluated the images with a relative bias towards the cooperator category (p < .01), and (4) females were more confident in detecting defectors (p < .05). According to facial microexpression analysis, defection was strongly linked with depressed lower lips and less opened eyes. Significant correlation was found between the intensity of micromimics and the rating of images in the cooperator‐defector dimension. In summary, facial expressions can be considered as reliable indicators of momentary social dispositions in the PDG. Females may exhibit an evolutionary‐based overestimation bias to detecting social visual cues of the defector face.  相似文献
