In a recent article, [Sergent, C. &; Dehaene, S. (2004). Is consciousness a gradual phenomenon? Evidence for an all-or-none bifurcation during the attentional blink, Psychological Science, 15(11), 720–729] claim to give experimental support to the thesis that there is a clear transition between conscious and unconscious perception. This idea is opposed to theoretical arguments that we should think of conscious perception as a continuum of clarity, with e.g., fringe conscious states [Mangan, B. (2001). Sensation’s ghost—the non-sensory “fringe” of consciousness, Psyche, 7, 18]. In the experimental study described in this article, we find support for this opposite notion that we should have a parsimonious account of conscious perception. Our reported finding relates to the hypothesis that there is more than one perceptual threshold [Merikle, P.M., Smilek, D. &; Eastwood, J.D. (2001). Perception without awareness: perspectives from cognitive psychology, Cognition, 79, 115–134], but goes further to argue that there are different “levels” of conscious perception. 相似文献

Some risk and protective factors differ in their importance to suicidal and nonsuicidal people. In this research we explore the cross-sectional differences between risk factors among suicidal adolescents and nonsuicidal adolescents by focusing on self-esteem. Sixty-five suicidal and 390 nonsuicidal adolescents were compared on Harter's Self-Perceived Profile for Adolescents, self-concept stability, seeking support, loneliness, and depression. Self-concept stability, loneliness, and peer support correlated differently with self-esteem. In multivariate regression analyses, variance in self-esteem was explained by depression and loneliness, and among nonsuicidal adolescents also by self-concept stability, support, and competencies. Loneliness and self-concept stability related differently to self-esteem in suicidal and nonsuicidal adolescents. When the aim is to enhance self-esteem, this difference may delineate suicidal subgroups that need special interventions. 相似文献

This study focuses on the impact of present ideological commitment on posttraumatic stress symptoms in former child soldiers living in exile. Eighteen men and two women (aged 25-37), who had joined different Tamil armed groups in Sri Lanka between the ages of 13 and 17 years, participated. The Impact of Event Scale was used to measure posttraumatic symptoms. Qualitative methods were used to investigate the participants' ideological commitment. Participants reported being exposed to many potentially traumatizing events, and had high scores on the Impact of Event Scale. Twenty-five percent of the sample showed strong ideological commitment to the "cause". Ideological commitment at the present seemed to predict better mental health when exposure was less intense and overwhelming. Time had a negative impact on ideological commitment. 相似文献

In neon color spreading displays, both a color illusion and perceptual transparency can be seen. In this study, we investigated the color conditions for the perception of transparency in such displays. It was found that the data are very well accounted for by a generalization of Metelli's (1970) episcotister model of balanced perceptual transparency to tristimulus values. This additive model correctly predicted which combinations of colors would lead to optimal impressions of transparency. Color combinations deviating slightly from the additive model also looked transparent, but less convincingly so. 相似文献

Scholars disagree about whether adolescent conduct problems (CPs) form a single behavioral syndrome or whether such problems are better conceptualized as different dimensions. The arguments raised by both sides are addressed and tested empirically by analysing data from a large general population sample of Norwegian adolescents (n = 9,342). Confirmatory factor analyses show that a single syndrome of CPs may be subdivided into three highly correlated factors. The first dimension, destructive covert, includes theft and vandalism, whereas the second, nondestructive covert, reflects avoidance of arenas under adult control. The last dimension, overt, includes school opposition and fighting. This three-factor model fits well for both girls and boys, and individuals in their early and late teens. Results from scale analyses are modestly to moderately indicative of a developmental continuum of severity of CPs ranging from nondestructive covert to overt to destructive covert. Taken together the findings imply that both a unidimensional and a multidimensional perspective on CPs are applicable in the general youth population. 相似文献

Adolescents are proportionately more frequently involved in traffic accidents than are other age groups. A strategy for promoting road safety is to change the attitudes likely to influence driving behavior. However, the lack of valid and reliable instruments to measure risk-taking attitudes makes it difficult to evaluate the effects of measures aimed at changing attitudes among young drivers and their passengers. The present study tested the psychometric qualities of a scale intended to measure adolescents' risk-taking attitudes to driving. The results are based on a self-completion questionnaire survey carried out among 3,942 adolescents and young adults, aged 16-23 years, in Norway in 1998/1999. Using both exploratory and confirmatory factor analyses, 11 dimensions of risk-taking attitudes were identified. Parametric as well as nonparametric methods were applied to test the homogeneity of items within each attitude dimension. The reliability and validity of the dimensions were satisfactory. The attitude dimensions were significantly correlated with self-reported driving behavior, as well as accident frequency. The application of the new measurement instrument in studies aimed at evaluating safety campaigns is discussed. 相似文献

As people with serious mental illness are viewed as consumers rather than patients, their views and needs are increasingly seen as essential to the treatment process. The aim of the present study is to add valuable knowledge about how to help patients by reporting what fully recovered schizophrenics, as consumers, had found helpful in their treatment as well as which factors contributed to their recovery. In addition to a semistructured interview, two instruments were used: the "UCLA Social Attainment Survey Premorbid Adjustment Scale" (SASPAS) to measure patients' premorbid adjustment and the "Global Assessment Scale" (GAS) to obtain an assessment of the present general functioning of the subjects. The results showed that a majority of the recovered subjects emphasized their own will-power and the human qualities in their therapists as helpful to them in the process towards recovery. The therapeutic relationships were characterized by the kindling and sustaining of hope in the clients. 相似文献

Referring to the diversity of psychoanalysis of today, a position called relational-oriented character analysis is discussed. It is stated that relation and character as concepts refer to different and partly contradictory points of view in psychoanalysis, the first one emphasising mobile, dynamic aspects of personality, the second underlining stable, structural aspects. The principle aim of the article is to argue how the two perspectives can be theoretically combined in an overriding object-relational (two-person) conception and to discuss some implications for analytic technique. Finally, convergences and differences with other positions or schools in contemporary psychoanalysis are suggested. 相似文献
