ABSTRACT

The aim of the present study was to examine differences in anxiety and depression related to differences in attachment models of the self and of others and whether personality traits mediate this relationship. The authors assessed attachment styles, anxiety, depression, and personality traits among 274 adult volunteers. Participants were classified into 4 attachment groups (secure, preoccupied, fearful, and dismissing–avoidant) according to K. Bartholomew's (1990) Bartholomew, K. 1990. Avoidance of intimacy: An attachment perspective. Journal of Social and Personal Relationships, 7: 147178. [Crossref], [Web of Science ®] [Google Scholar] model. The present authors found significant differences among attachment groups on anxiety and depressive symptoms with attachment styles involving a negative self-model showing higher scores than attachment styles characterized by a positive self-model. The authors also found that differences between attachment styles in anxiety and depression remained significant when personality factors related to attachment prototypes were entered as covariates. Results indicate that secure attachment in adults was associated with better mental health, while insecure attachment styles characterized by negative thinking about the self were associated with higher depression and anxiety scores. Our findings seem to evidence that attachment and personality are only partly overlapping and that attachment cannot be considered as redundant with personality in the explanation of psychological disease.  相似文献

Bayley Mental scores were significantly related to several concurrent ratings of infant and maternal testroom behavior when firstborn black male infants were 14 months (N = 49), 18 months (N = 34), and 22 months of age (N = 32). With increasing age, social responsiveness played a relatively less important role in successful performance, while object responsiveness became increasingly important. Bayley Motor scores were related to many fewer ratings than the Mental scores. Gross Muscle Coordination was related to performance at all three ages, and Energy ratings at two of the three ages. For both the Mental and Motor scores, fewer relationships were observed at the 18-month testings as compared to the 14- and 22-month testings. By 22 months, infants scoring higher on the Bayley Mental scale had mothers who were more highly involved with their child's achievement as judged by testroom behaviors.  相似文献

The purpose of this study was to investigate linkages between adolescent self-monitoring, global social competence, and parenting and family environment dimensions of support and encouragement of autonomy. The sample consisted of 233 young women and 199 young men at 2 southwestern universities. The primary measures used were the Family Environment Scale (R. H. Moos, 1981), the Parent Behavior Form (L. Worell & J. Worell, 1974), the revised Self-Monitoring Scale (M. Snyder, 1987), and the Texas Social Behavior Inventory (R. Helmreich, J. Stapp, & C. Ervin, 1974). Findings indicated that family variables are more strongly associated with social competence than with self-monitoring; family support was, overall, a more important ingredient of social competence than was autonomy. Women and men had different patterns of associations among specific variables.  相似文献

This cross-cultural, developmental study of understanding of the physics of a balance scale involved 2 age groups (5- and 22-year-olds) in 2 countries (the United States and Zimbabwe). A factorial design was used. Each participant solved 6 types of balance scale problems, and the patterns of errors for these problem types were analyzed to determine which rules and concepts the participant used (e.g., whether number of weights was considered). As expected, on average, older participants were more accurate than younger participants, although significant age differences in the Zimbabwean sample were not found for problems solved by weight or distance cues. One finding differing from earlier research was that problems in which the beam balanced were more difficult for all participants. Generally, understanding of the physics of a balance scale appeared fairly similar in the 2 countries. Some cultural practices may account for the findings—in particular, the availability of preschool and age at time of academic specialization in higher education.  相似文献

The domain-specific hypothesis of L. Cosmides (1989) and L. Cosmides and J. Tooby (1989, 1992) positing that conditional logic has its origin in the evolution of social exchange and in the detection of potential cheaters was tested against a more domain-general hypothesis positing that adult reasoning is logical and that errors in conditional reasoning arise from misunderstandings, not from a lack of logicality. The results of 5 experiments with undergraduate students (n = 682 for Experiments 1-4; n = 188 for Experiment 5), which involved a series of selection tasks that yielded specific predictions about participant performance, were not consistent with the cheater detection hypothesis. Findings supported the misunderstandings hypothesis and imply that adults possess general-purpose logical competence versus domain-specific modules.  相似文献

Alexithymia prevents people from understanding and adopting verbal language to describe and regulate one’s emotions. Recent studies have found that alexithymia symptoms also impact on young people’s academic achievement. Nevertheless, it is worth investigating risk and protective roles played by students’ academic anxiety and resilience, respectively. The authors expected that students’ anxiety and resilience mediated the effect of alexithymia symptoms on students’ academic burnout and performance. A sample of 257 university students answered self-report questionnaires about alexithymia, academic anxiety and resilience, and academic burnout and performance. Mediation analyses were performed by the structural equation model. Anxiety acted as a mediator between alexithymia and academic burnout and performance. Furthermore, resilience mediated the effect of alexithymia on burnout, but not on academic performance. The study provides support for preventing alexithymia consequences on young people’s academic career by reducing their anxiety and promoting academic resilience. Implications of intervention programs were discussed.  相似文献

Hikikomori (social withdrawal that lasts six months or longer) is a growing problem among Japanese adolescents and young adults, with recent estimates that approximately 1% of Japanese youths will suffer from an episode of hikikomori in their lifetimes. What remains unclear is whether hikikomori is a culture-bound syndrome or a condition impacting youths around the globe. Hence, the self-reported prevalence and psychosocial correlates of past experiences with hikikomori were examined in cross-sectional samples of university students from Singapore (n?=?147), Nigeria (n?=?151), and the United States (n?=?301). Following tests of measurement invariance, comparisons showed that past experiences with hikikomori were related to elevated levels of current loneliness and depressive symptoms in each sample. However, analyses also revealed evidence of cultural variation in both the prevalence and the psychosocial correlates associated with past experiences of hikikomori, which taken together, provide preliminary evidence that the culture-bound characterization of hikikomori may not be appropriate.  相似文献

Researchers assessed 58 preschoolers' reactions to an unfamiliar person and unfamiliar objects in their familiar home environment. Children participated in a 30-min procedure designed to elicit behavioral inhibition, including (a) a free-play period with a stranger present, (b) a structured interaction with the stranger, and (c) uncertainty-eliciting tasks. Behaviors representing the child's reactions toward the mother, stranger, and novel objects were coded. Mothers completed a temperament scale. Preschoolers exhibited behaviors indicative of inhibition toward unfamiliar social and nonsocial stimuli; behaviors remained stable across increasingly intrusive episodes. The approach/withdrawal component of temperament was related to behavioral inhibition. Individual differences in mood did not appear to be related to differences in inhibition. Parent reported temperament was related to researcher-observed behaviors.  相似文献

Action perception is selective in that observers attend to and encode certain dimensions of action over others. But how flexible is action perception in its selection of perceptual information? One possibility is that observers consistently attend to particular dimensions of action over others across different contexts. Another possibility, tested here, is that observers flexibly vary their attention to different dimensions of action based on the context in which action occurs. We investigated 9.5-month-old infants’ and adults’ ability to attend to drop height under varying contexts—aiming to drop an object into a narrow container versus a wide container. We predicted differential attention to increases in aiming height for the narrow container versus the wide container because an increase in aiming height has a differential effect on success (i.e., getting the object into the container) depending on the width of the container. Both adults and infants showed an asymmetry in their attention to aiming height as a function of context; in the wide container condition increases and decreases in aiming height were equally detectable, whereas in the narrow container condition observers more readily discriminated increases over decreases in aiming height. These results indicate that action perception is both selective and flexible according to context, aiding in action prediction and infants’ social–cognitive development more broadly.  相似文献

The aim of the study was to explore the psychophysiological concomitants of self‐reported behavioral inhibition system (BIS) sensitivity in adolescents (12 to 17 years old) supposed to be at risk for anxiety disorders. Twenty participants with high scores in self‐reported BIS sensitivity (at‐risk group) were matched in age and sex to 20 participants scoring in the normal range in BIS sensitivity (control group). Negative affect, negative emotion regulation style, and anxiety symptomatology were assessed by means of self‐reported measures. Cardiac and electrodermal response signals were recorded during baseline, paced breathing, exposure to an attentional task with response cost and fear‐relevant slides conditions. The at‐risk group exhibited higher scores on measures of negative affect, negative emotion regulation style, and anxiety symptomatology than their control counterparts. After controlling for negative styles of emotion regulation, groups did not differ in skin conductance reactivity during the attentional task with response cost, but participants at risk exhibited more nonspecific skin conductance responses than the control group during baseline recording. Regarding the cardiac concomitants, participants at risk presented lower vagal tone at resting conditions as compared to participants in the control group. Additionally, at‐risk participants exhibited lower flexibility across experimental conditions in heart rate and cardiac sample entropy measures than participants in the control group. These findings add knowledge on psychophysiological concomitants of BIS sensitivity and are discussed in light of associations between temperament and development of anxiety disorders in youth. They show how psychophysiological patterns observed in resting conditions could be useful endophenotypes to reliably detect individuals at risk before the disorder onset.  相似文献
