Two experiments explored age differences in response to reminders of death. Terror management research has shown that death reminders lead to increased adherence to and defense of one's cultural worldview. In Study 1, the effect of mortality salience (MS) on evaluations of moral transgressions made by younger and older adults was compared. Whereas younger adults showed the typical pattern of harsher judgments in response to MS, older adults did not. Study 2 compared younger and older adults' responses to both the typical MS induction and a more subtle death reminder. Whereas younger adults responded to both MS inductions with harsher evaluations, older adults made significantly less harsh evaluations after the subtle MS induction. Explanations for this developmental shift in responses to reminders of death are discussed.  相似文献

This paper describes the phenomenological features of early childhood onset obsessive compulsive disorder (OCD; defined as children meeting DSM-IV criteria for OCD with age of onset <8 years). Fifty-eight children (ages 4–8) were included in the sample. OCD and comorbid diagnoses were determined by structured interview, and OCD severity was measured using the Children’s Yale-Brown Obsessive Compulsive Scale (CY-BOCS). Mean age of OCD onset was almost five, and mean age of presentation was between 6 and 7. Mean symptom severity was in the moderately severe range. Comorbidity and family history of OCD were common. Contamination and aggressive/catastrophic obsessions and washing and checking compulsions were endorsed most frequently. Results indicate that early childhood onset OCD may have a lower boy to girl ratio and lower rates of depressive disorders, but may be similar to later childhood onset OCD in terms of OCD symptom presentation and severity.  相似文献

A dual evaluation technique exposed measurable and identifiable discrepancies between a retarded child's functioning as measured by standardized tests and the parental perception of that functioning. The sample consisted of 25 mothers and their children ranging in age from 3½ years to 15½ years. The Revised Stanford-Binet was employed for both parent and child. The examiner preceded the administration of the Binet to the mother with an explanation that she was to answer the questions and perform the required tasks in the exact manner she thought her child would respond. The test was administered and scored according to standardized procedures. Although the difference between the two sets of IQ scores was statistically significant, and the hypothesis that mothers would tend to over-estimate their children's intelligence scores was confirmed, the difference was not as great as might be expected from results of previous studies.  相似文献

A large body of work has investigated the association between birth weight and ADHD and has resulted in mixed findings with regard to the direction and magnitude of this association. Despite the vast amount of research on this topic, a comprehensive and systematic quantification of the association between birth weight and ADHD has yet to be undertaken. A meta-analysis of 88 unique studies (N?=?4,645,482) was conducted to quantify the overall effect size of birth weight on ADHD symptoms. Several variables were examined as moderators that may contribute to systematic variation in effect sizes. Overall, birth weight was found to have a small, but significant, association with ADHD symptoms such that individuals born at lower birth weights manifested greater symptoms of ADHD (r?=??0.15). Sample type, mean birth weight of the sample, geographic region, the informant of ADHD symptoms, ADHD symptom measurement method, and race were all found to contribute significantly to heterogeneity in effect sizes. Notably, several early life risk factors previously found to be associated with both ADHD and birth weight, gestational age and prenatal smoking exposure, were not found to contribute to heterogeneity in effect sizes. The findings of the current analyses align with the growing recognition that early life adversity contributes to neurodevelopmental difficulties, and the findings highlight the importance of a better understanding of the mechanisms underlying the association between early life risk factors and adverse neurodevelopmental sequela, such as that observed in ADHD.  相似文献

The relationship between an individual’s cognitive abilities and other behavioural attributes is complex, yet critical to understanding how individual differences in cognition arise. Here we use western mosquitofish, Gambusia affinis, to investigate the relationship between individual associative learning performance in numerical discrimination tests and independent measures of activity, exploration, anxiety and sociability. We found extensive and highly repeatable inter-individual variation in learning performance (r = 0.89; ICC = 0.89). Males and females exhibited similar learning performance, yet differed in sociability, activity and their relationship between learning and anxiety/exploration tendencies. Sex-specific multivariate behaviour scores successfully predicted variation in individual learning performance, whereas combined sex analyses did not. Female multivariate behaviour scores significantly predict learning performance across females (ρ = 0.80, p = 0.005) with high-performing female learners differentiated from female non-learners and low-performing learners by significant contributions of activity and sociability measures. Meanwhile, males of different learning performance levels (high-, low- and non-learners) were distinguished from each other by unique behavioural loadings of sociability, activity and anxiety/exploration scores, respectively. Our data suggest that despite convergence on learning performance, the sexes diverge in cognitive–behavioural relationships that are likely products of different sexual selection pressures.  相似文献

This article contains a review of Frozen, the animated Disney film about a princess who later becomes a queen, with magical powers that allow her to create ice and snow. The author demonstrates how the film clearly illustrates several important principles from the perspective of relational-cultural theory (RCT), namely connection, disconnection, and the central relational paradox. Elsa’s character development is explored through the RCT lens, particularly the dilemma she faces with regard to how to remain authentic to her unique identity while also maintaining relationships. Implications and suggestions are offered to counselors and counselor educators for how to use these examples in clinical and educational settings.  相似文献

Previous research has indicated that the blockade of H(3)-type histamine receptors may improve attention and memory in normal rodents. The purpose of this study was to determine if ciproxifan, an H(3) receptor antagonist, could alleviate the hyperactivity and cognitive deficits observed in a transgenic mouse model (APP(Tg2576)) of Alzheimer's disease. APP(Tg2576) mice displayed significantly greater locomotor activity than wild-type mice, but APP(Tg2576) mice provided with daily ciproxifan treatment showed activity levels that did not differ from wild-type mice. In the swim maze, APP(Tg2576) mice exhibited significantly longer escape latencies, but the APP(Tg2576) mice treated daily with ciproxifan had latencies that were indistinguishable from controls. In probe trials conducted one hour after the last training trial, ciproxifan-treated APP(Tg2576) mice spent more time near the previous platform location and made more crossings of this area than did saline-treated APP(Tg2576) mice. APP(Tg2576) mice also demonstrated a significant impairment in the object recognition task that was reversed by acute treatment with ciproxifan (3.0mg/kg). These data support the idea that modulation of H(3) receptors represents a novel and viable therapeutic strategy in the treatment of Alzheimer's disease.  相似文献

Understanding how couples navigate and negotiate the challenges and demands of pregnancy has important implications for family health. The aim of this study was to apply a multidimensional model of intimate relationship quality in a sample of 154 pregnant, cohabitating couples, to investigate the association between a range of intimate relationship processes (i.e., emotional intimacy, conflict management, sexual quality, received respect and acceptance, and received support) and the global relationship satisfaction of each partner. Semistructured clinical interviews were administered to each partner assessing multiple qualities of the relationship, and participants completed home surveys of global relationship satisfaction each day for 14 days. Results demonstrated that multiple dimensions of the intimate relationship were associated with greater relationship satisfaction. Some processes (e.g., degree of emotional intimacy and closeness, conflict management) had larger effects on relationship satisfaction than others (e.g., quality of the sexual relationship). Furthermore, some processes were more important for maternal than paternal satisfaction (e.g., emotional intimacy, support, respect). Finally, results varied, to some degree, as a function of whether parents were transitioning to parenthood for the first time. We discuss the implications of adopting a multidimensional approach to studying the specific relationship processes associated with global relationship satisfaction and present implications for clinicians working with couples navigating the transition into parenthood.  相似文献
