Both working and immediate memories were assessed every 4h by specific short-term memory tasks over sustained wakefulness in 12 patients with obstructive sleep apnea and hypopnea syndrome (OSAHS) and 10 healthy controls. Results indicated that OSAHS patients exhibited lower working memory performances than controls on both backward digit span and complex Sternberg tasks. Speed and accuracy on Sternberg tasks were affected by memory load in both groups. However, immediate memory was not impaired in OSAHS patients. Diurnal and nocturnal SaO(2) were correlated with speed and accuracy high-speed memory scanning performance on Sternberg tasks in patients. These results suggest specific working memory deficits associated with OSAHS over sustained wakefulness with a possible deficiency in the central executive responsible for the higher information processing, in addition to a potentially insufficient storage capacity. Among OSAHS patients, working memory ability involved in high-speed memory scanning may be impaired by chronic hypoxemia. 相似文献

The main purpose of this study was to explore the dimensionality of the borderline personality disorder in nonclinical young adults by means of the Borderline Personality Questionnaire (BPQ; Poreh et al., 2006). We also studied the phenotypic expression of the borderline personality traits as a function of participants' gender and age, and the relationship between BPQ subscales and measures of depressive symptoms, anxiety, stress, hallucinatory predisposition, and paranoid ideation. The sample comprised 809 young adults, 562 (69.5%) were women, with a mean age of 20.2 years (SD = 2.9). The results indicate that the BPQ self-report has adequate psychometric properties. The levels of internal consistency for the BPQ subscales ranged between .78 and .93. Analysis of the internal structure of the BPQ subscales yielded a one-dimensional solution. In contrast, second-order principal components analysis at the item level yielded a five-dimensional solution. Likewise, statistically significant differences in the mean scores of the borderline personality traits as a function of participants' gender and age were found. The BPQ subscales correlated significantly with measures of depression, anxiety, stress, paranoid ideation, and hallucinatory predisposition. These results help to improve our understanding of the dimensional structure of the borderline personality in the general population. Future research should continue to identify participants who are at risk for the development of borderline personality disorder and facilitating the development of early detection and prevention programs. 相似文献

This study examined the associations between infant and childhood growth and severe personality disorders. Among 4,689 men and 4,200 women of the Helsinki Birth Cohort Study 1934-1944, 81 men and 68 women had been hospitalized with an ICD (-8, -9, -10) diagnosis of personality disorder in adulthood. Among men, slower gain in BMI between birth and 6 months, faster gain in weight and BMI between 6 months and 1 year, and slower gains in them between 7 and 11 years of age predicted an increased risk of hospitalization for personality disorders. Thinness at 6 months and again at 11 years also showed significant association with personality disorders among men. Among women, slower gain in height between 2 and 7 years predicted hospitalization for personality disorders. Our findings show the importance of early growth as a vulnerability factor of personality disorders severe enough to justify hospitalization. 相似文献

Over the last decade or so, the Internet has become a privileged media for advertisement. Despite this increase in popularity, several studies suggested that Internet users ‘avoid’ looking at ads (what is often referred to as the banner blindness phenomena). This conclusion, however, rests mostly on indirect evidence that participants do not remember the ad content. Therefore, it is unclear whether participants actually fixated the ads and how their gaze behaviour is related to memory for the ad. In the present study, we investigated whether Internet users avoid looking at ads inserted on a non‐search website using an analysis of eye movements, and if the ad content is kept in memory. Our results show that most participants fixate the ads at least once during their website visit. Moreover, even though the congruency between the ad and the editorial content had no effect on fixation duration on the ad, congruent ads were better memorised than incongruent ads. This study provides a novel and systematic method for assessing the processing and retention of advertisements during a website visit. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

Due to the risk of fetal anomaly, pregnant women of advanced maternal age are given the option to undergo amniocentesis. In
our study we aimed to describe couples’ decision-making process regarding amniocentesis, and assess whether it is influenced
by marital intimacy and men’s participation in genetic counseling. During pregnancy, 112 couples answered the Personal Assessment
of Intimacy in Relationships questionnaire and scales regarding the decision to undergo amniocentesis. Most couples shared
and reached an agreement regarding this decision. Higher levels of marital engagement and communication, but not men’s participation,
were associated with higher agreement, influence, and decision-sharing. Clinical implications are discussed. 相似文献

Drawing on evolutionary psychology, social exchange styles were conceptualized in terms of two dimensions of individual differences in approaching exchange relationships: Benefit‐seeking and cost‐vigilance. In Study 1, a principal components analysis of the Social Exchange Styles Questionnaire (SESQ) in 156 undergraduates confirmed the presence of two dimensions that were very similar to the expected dimensions: Equitable alliance building (EAB) and vigilant alliance management (VAM). The SESQ scales showed good internal consistency and construct validity. Multiple regressions confirmed that social exchange styles were distinct from other personality variables. In Study 2, multilevel modelling conducted on 45 small work groups demonstrated that EAB positively predicted members' subjective performance, while VAM positively predicted objective performance. Theoretical questions and future research directions are discussed. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

We address the question as to whether judgmental overconfidence, as assessed by probability miscalibration, is related to positive illusions about the self. We first demonstrate that judgmental overconfidence measured with interval production procedures can be considered a trait, due to correlations observed in miscalibration scores in two sets of general‐knowledge questions of varying difficulty administered at different times. In addition, the hard‐easy effect operated in different ways on overprecision and self‐placement of one's performance relative to others: The more difficult the calibration task, the greater the over precision but the greater the under placement of one's performance. Finally, there was no evidence that miscalibration was related to dispositional optimism and self‐efficacy. A second study extended these results by including further measures of disposition to experience positive illusions such as unrealistic optimism, a general tendency to consider oneself “better‐than‐average,” and two indexes of dispositional perception of control. The positive illusion measures showed considerable inter‐correlations, but did not correlate with miscalibration on the interval production task, and correlated negatively with optimism concerning societal risks. A final study replicated this pattern of findings, but showed that disposition to positive illusions did predict miscalibration on the same questions measured with a probability evaluation technique. Our research demonstrates that “overconfidence” is not a unitary construct, but a series of overlapping ones. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

Theoretical perspectives and research in sociology, anthropology, sociolinguistics, and cultural psychology converge in recognizing the significance of children's time spent in various activities, especially in the family context. Knowing how children's time is deployed, however, only gives us a partial answer to how children acquire competence; the other part must take into account the culturally constructed meanings of activities, from the perspective of those who organize and direct children's daily lives. In this article, we report on a study of children's routine daily activities and on the meanings that parents attribute to them in six Western middle-class cultural communities located in Italy, The Netherlands, Poland, Spain, Sweden, and the United States (N = 183). Using week-long time diaries kept by parents, we first demonstrate similarities as well as significant differences in children's daily routines across the cultural samples. We then present brief vignettes--"a day in the life" --of children from each sample. Parent interviews were coded for themes in the meanings attributed to various activities. Excerpts from parent interviews, focusing on four major activities (meals, family time, play, school- or developmentally related activities), are presented to illustrate how cultural meanings and themes are woven into parents' organization and understanding of their children's daily lives. The results of this mixed-method approach provide a more reliable and nuanced picture of children's and families' daily lives than could be derived from either method alone. 相似文献

Different approaches to expertise and argumentation are discussed. After introducing the problem of expertise and its present
day significance in a historical context, various connections with the study of arguments are highlighted. The need for and
potential of argumentation analysis to contribute to existing research in social epistemology, science studies, and cognitive
science, is discussed, touching on the problems of reasoning and argumentation, embodiment, tacit knowledge, expert context
versus public context, expert disagreement, persuasion versus justification, and argument analysis as meta-expertise. As the
arguments used by experts constitute a boundary object, we presume that a dialogue format is suitable to address central problems
of the special issue “Rethinking Arguments from Experts”. 相似文献

Does emotional intelligence promote behavior that strictly benefits the greater good, or can it also advance interpersonal deviance? In the investigation reported here, we tested the possibility that a core facet of emotional intelligence--emotion-regulation knowledge--can promote both prosocial and interpersonally deviant behavior. Drawing from research on how the effective regulation of emotion promotes goal achievement, we predicted that emotion-regulation knowledge would strengthen the effects of other-oriented and self-oriented personality traits on prosocial behavior and interpersonal deviance, respectively. Two studies supported our predictions. Among individuals with higher emotion-regulation knowledge, moral identity exhibited a stronger positive association with prosocial behavior in a social dilemma (Study 1), and Machiavellianism exhibited a stronger positive association with interpersonal deviance in the workplace (Study 2). Thus, emotion-regulation knowledge has a positive side and a dark side. 相似文献
