The present study examined children's borderline personality features and their association with developmentally appropriate factors, including friendship exclusivity, forms of aggression and peer maltreatment with a non‐Western urban sample. The participants consisted of 234 Japanese preadolescents who were in the fourth and fifth grade (50% girls; ages: 9–11). Results of correlational analyses show that borderline personality features were stable during a six‐month period (r = 0.55). Moreover, results of mixed linear models indicate that friendship exclusivity was associated with elevated borderline personality features concurrently and longitudinally, after controlling for the effects of physical and relational aggression. Physical aggression (not relational aggression) and physical victimization (not relational victimization) also predicted relative increases in borderline personality features. These findings are discussed from a cultural‐developmental perspective. 相似文献

Spatial representations of time are a ubiquitous feature of human cognition. Nevertheless, interesting sociolinguistic variations
exist with respect to where in space people locate temporal constructs. For instance, while in English time metaphorically
flows horizontally, in Mandarin an additional vertical dimension is employed. Noting that the bilingual mind can flexibly
accommodate multiple representations, the present work explored whether Mandarin–English bilinguals possess two mental time
lines. Across two experiments, we demonstrated that Mandarin–English bilinguals do indeed employ both horizontal and vertical
representations of time. Importantly, subtle variations to cultural context were seen to shape how these time lines were deployed. 相似文献

Cognitive enhancing substances such as amphetamine and modafinil have become popular in recent years to improve acute cognitive performance particularly in environments in which enhanced cognition or intelligence is required. Nutraceutical nootropics, which are natural substances that have the ability to bring about acute or chronic changes in cognition have also been gaining popularity in a range of settings and applications including the workplace, driving and in the amelioration of age related cognitive decline. Huperzine A, Vinpocetine, Acetyl-l-carnitine, Rhodiola Rosea and Alpha-lipoic Acid are popular nutritional supplements that have shown promising benefits in improving a range of biological (e.g., blood flow, anti-inflammatory, anti-oxidant, and direct neurotransmitter effects) and cognitive processes from in vitro, animal and human clinical research. We report here the first human randomized clinical trial for cognition in which we administer a combination of Huperzine A, Vinpocetine, Acetyl-l-carnitine, R. Rosea and Alpha-lipoic acid (called Ceretrophin) vs placebo. Sixty participants (40 females and 20 males, with a mean age of 45.4 years, SD = 12.6) completed either the odd or even items from the Raven Advanced Progressive Matrices (APM) at baseline and the opposite odd or even items at week 4 after consuming either the combination nootropic or placebo. A significant study visit (time) × treatment condition interaction was found: F (1, 57) = 7.279, p = 0.009, partial η2 = .113, with paired samples t-tests revealing a significant improvement in mean APM score from baseline to retest (week 4) (t(34) = ? 4.045, p < .001) for the Ceretrophin? group. Improvements in APM scores could be attributed to the active intervention over the placebo, indicating that the treatment improved general intelligence. Implications for improving our understanding of the biological basis of intelligence and pharmacologically improving human cognition are discussed. 相似文献

Psychopathy is a serious personality disorder of which impulsivity is a key component. However, impulsivity is a multidimensional construct, with multiple approaches to measurement, and different measures may be differentially implicated in psychopathy. This study investigated the relationship between psychopathy as assessed by the Psychopathic Personality Inventory-Revised (PPI-R; Lilienfeld & Widows, 2005), a personality measure of impulsivity (Barratt Impulsiveness Scale-11), and four behavioural measures of impulsivity (GoStop Impulsivity Paradigm, Two Choice Impulsivity Paradigm, Delay Discounting Task, Iowa Gambling Task). A nonclinical sample (N = 80) was recruited from the local community to advance understanding of psychopathy in non-incarcerated samples. The results indicated that the personality measure of impulsivity was strongly correlated with the PPI-R, while the behavioural measures were either not correlated or only weakly correlated with the PPI-R. The results are discussed in terms of the multifaceted nature of impulsivity and the need for the further development of behavioural measures of impulsivity, given their importance in clinical assessment and intervention. 相似文献

Self-referencing benefits item memory, but little is known about the ways in which referencing the self affects memory for details. Experiment 1 assessed whether the effects of self-referencing operate only at the item, or general, level or whether they also enhance memory for specific visual details of objects. Participants incidentally encoded objects by making judgements in reference to the self, a close other (one's mother), or a familiar other (Bill Clinton). Results indicate that referencing the self or a close other enhances both specific and general memory. Experiments 2 and 3 assessed verbal memory for source in a task that relied on distinguishing between different mental operations (internal sources). The results indicate that self-referencing disproportionately enhances source memory, relative to conditions referencing other people, semantic, or perceptual information. We conclude that self-referencing not only enhances specific memory for both visual and verbal information, but can also disproportionately improve memory for specific internal source details. 相似文献

Two studies examined whether perceiving a partner as responsive leads people to be more expressive with that partner, and whether the effects of perceived partner responsiveness on expressivity are moderated by self-esteem. In Study 1, female undergraduates with high or low self-esteem disclosed to a fictitious partner about a sad event. Participants either received an understanding, caring, and validating written response from their ostensible partner or did not receive a response. In Study 2, participants wrote an email, supposedly to another participant, about a sad event and received either a highly responsive or a non-responsive email response. In both studies, partner responsiveness increased expressivity among individuals with low self-esteem but not among individuals with high self-esteem. These results provide the first experimental evidence for Reis and Shaver's (1988) theorizing about responsiveness and self-disclosure. 相似文献

Based on the cognitive-social health information processing model, we identified cognitive profiles of women at risk for breast and ovarian cancer. Prior to genetic counselling, participants (N = 171) completed a study questionnaire concerning their cognitive and affective responses to being at genetic risk. Using cluster analysis, four cognitive profiles were generated: (a) high perceived risk/low coping; (b) low value of screening/high expectancy of cancer; (c) moderate perceived risk/moderate efficacy of prevention/low informativeness of test result; and (d) high efficacy of prevention/high coping. The majority of women in Clusters One, Two and Three had no personal history of cancer, whereas Cluster Four consisted almost entirely of women affected with cancer. Women in Cluster One had the highest number of affected relatives and experienced higher levels of distress than women in the other three clusters. These results highlight the need to consider the psychological profile of women undergoing genetic testing when designing counselling interventions and messages. 相似文献

Temporal patterns of anxious and depressed mood in generalized anxiety disorder: a daily diary study
Research suggests that anxiety disorders tend to temporally precede depressive disorders, a finding potentially relevant to understanding comorbidity. The current study used diary methods to determine whether daily anxious mood also temporally precedes daily depressed mood. 55 participants with generalized anxiety disorder (GAD) and history of depressive symptoms completed a 21-day daily diary tracking anxious and depressed mood. Daily anxious and depressed moods were concurrently associated. Daily anxious mood predicted later depressed mood at a variety of time lags, with significance peaking at a two-day lag. Depressed mood generally did not predict later anxious mood. Results suggest that the temporal antecedence of anxiety over depression extends to daily symptoms in GAD. Implications for the refinement of comorbidity models, including causal theories, are discussed. 相似文献
