The theory and measurement of ego development (Loevinger in Ego development: Conceptions and theories. Jossey-Bass, San Francisco, 1976) have enjoyed success in the empirical literature as a means of conceptualizing psychological maturity. One unresolved issue concerns the uncertain relationship between ego development and positive adjustment or well-being. The current study tests the hypothesis that ego development in the transition to young adulthood entails an increase in internalizing symptoms and a decrease in externalizing symptoms of psychopathology. Two samples of college students (total n = 263, age range 18–22 years) completed a measure of ego development, the Washington University Sentence Completion Test (WUSCT; Hy and Loevinger in Measuring ego development. Lawrence Erlbaum, Mahwah, 1996), and either the Defense Mechanisms Inventory (DMI; Ihilevich and Gleser in Defense mechanisms: Their classification, correlates, and measurement with the Defense Mechanisms Inventory. Psychological Assessment Resources, Odessa, 1993) or select scales from the Personality Assessment Inventory (PAI; Morey in Personality Assessment Inventory professional manual 2. Psychological Assessment Resources, Lutz, 2007). Results indicate that WUSCT scores are positively correlated with internalizing defense preferences, anxiety-related disorders, unstable mood and identity, and sense of stress. WUSCT scores are negatively correlated with externalizing defense preferences and alcohol problems, and with aggression in males. These findings are consistent with the hypothesis that ego development is related to the specific type, rather than overall level, of psychopathology experienced by young adults.  相似文献

Positive parenting has been related both to lower cortisol reactivity and more adaptive temperament traits in children, whereas elevated cortisol reactivity may be related to maladaptive temperament traits, such as higher negative emotionality (NE) and lower positive emotionality (PE). However, no studies have examined whether hypothalamic‐pituitary‐adrenal axis activity, as measured by cortisol reactivity, moderates the effect of the quality of the parent–child relationship on changes in temperament in early childhood. In this study, 126 3‐year‐olds were administered the Laboratory Temperament Assessment Battery (Lab‐TAB; Goldsmith et al., 1995) as a measure of temperamental NE and PE. Salivary cortisol was collected from the child at 4 time points during this task. The primary parent and the child completed the Teaching Tasks battery (Egeland et al., 1995), from which the quality of the relationship was coded. At age 6, children completed the Lab‐TAB again. From age 3 to 6, adjusting for age 3 PE or NE, a better quality relationship with their primary parent predicted decreases in NE for children with elevated cortisol reactivity and predicted increases in PE for children with low cortisol reactivity. Results have implications for our understanding of the interaction of biological stress systems and the parent–child relationship in the development of temperament in childhood.  相似文献

Research suggests that early identification of developmental dyslexia is important for mitigating the negative effects of dyslexia, including reduced educational attainment and increased socioemotional difficulties. The strongest pre‐literacy predictors of dyslexia are rapid automatized naming (RAN), phonological awareness (PA), letter knowledge, and verbal short‐term memory. The relationship among these constructs has been debated, and several theories have emerged to explain the unique role of each in reading ability/disability. Furthermore, the stability of identification of risk based on these measures varies widely across studies, due in part to the different cut‐offs employed to designate risk. We applied a latent profile analysis technique with a diverse sample of 1215 kindergarten and pre‐kindergarten students from 20 schools, to investigate whether PA, RAN, letter knowledge, and verbal short‐term memory measures differentiated between homogenous profiles of performance on these measures. Six profiles of performance emerged from the data: average performers, below average performers, high performers, PA risk, RAN risk, and double‐deficit risk (both PA and RAN). A latent class regression model was employed to investigate the longitudinal stability of these groups in a representative subset of children (= 95) nearly two years later, at the end of 1st grade. Profile membership in the spring semester of pre‐kindergarten or fall semester of kindergarten was significantly predictive of later reading performance, with the specific patterns of performance on the different constructs remaining stable across the years. There was a higher frequency of PA and RAN deficits in children from lower socioeconomic status (SES) backgrounds. There was no evidence for the IQ–achievement discrepancy criterion traditionally used to diagnose dyslexia. Our results support the feasibility of early identification of dyslexia risk and point to the heterogeneity of risk profiles. These findings carry important implications for improving outcomes for children with dyslexia, based on more targeted interventions.  相似文献

Many studies have found that a majority of boys and girls prefer to play with toys that are typed to their own gender but there is still uncertainty about the age at which such sex differences first appear, and under what conditions. Applying a standardized research protocol and using a selection of gender‐typed toys, we observed the toy preferences of boys and girls engaged in independent play in UK nurseries, without the presence of a parent. The 101 boys and girls fell into three age groups: 9 to 17 months, when infants can first demonstrate toy preferences in independent play (N = 40); 18 to 23 months, when critical advances in gender knowledge occur (N = 29); and 24 to 32 months, when knowledge becomes further established (N = 32). Stereotypical toy preferences were found for boys and girls in each of the age groups, demonstrating that sex differences in toy preference appear early in development. Both boys and girls showed a trend for an increasing preference with age for toys stereotyped for boys. Theoretical implications of the findings are discussed with regard to biological predispositions, cognitive development and environmental influences on toy preference.

Individual differences in fear generalisation have been proposed to play a role in the aetiology and/or maintenance of anxiety disorders, but few data are available to directly support that claim. The research that is available has focused mostly on generalisation of peripheral and central physiological fear responses. Far less is known about the generalisation of avoidance, the behavioural component of fear. In two experiments, we evaluated how neuroticism, a known vulnerability factor for anxiety, modulates an array of fear responses, including avoidance tendencies, towards generalisation stimuli (GS). Participants underwent differential fear conditioning, in which one conditioned stimulus (CS+) was repeatedly paired with an aversive outcome (shock; unconditioned stimulus, US), whereas another was not (CS?). Fear generalisation was observed across measures in Experiment 1 (US expectancy and evaluative ratings) and Experiment 2 (US expectancy, evaluative ratings, skin conductance, startle responses, safety behaviours), with overall highest responding to the CS+, lowest to the CS? and intermediate responding to the GSs. Neuroticism had very little impact on fear generalisation (but did affect GS recognition rates in Experiment 1), in line with the idea that fear generalisation is largely an adaptive process.  相似文献

Miscarriage is a devastating yet common experience shared by women and their partners. Doctors often recommend that couples attempt to conceive again after the experience of a miscarriage, yet little is known about the emotional toll of conception following miscarriage. In the current study, we addressed two primary research questions: (a) How does experiencing a miscarriage relate to recalled emotional experiences of uncertainty surrounding efforts to conceive again? and (b) does gender moderate the association between miscarriage and retrospective accounts of emotions surrounding efforts to conceive? An online sample of parents from across the U.S. (N?=?429; 84.4 % married or cohabiting) reported their number of prior miscarriages and completed online questionnaires assessing recalled psychological adjustment (anxiety, rumination, positive and negative emotions) during their efforts to conceive their youngest child. In addition, they provided written responses regarding their experiences during this time. Participants’ responses were quantitatively analyzed for word use using LIWC, a text-analysis software program, to obtain an observational indicator of emotions. For women but not men, miscarriage was associated with recalled anxiety, rumination, and negative emotions surrounding efforts to conceive a child, as well as the use of more negative emotion, sadness, and anxiety words when describing efforts to conceive. Thus, miscarriage seemed to taint the emotional experience of trying to conceive again, and this consequence seemed particularly poignant for women.  相似文献

This study focused on gaining a better understanding of the neuropsychological abilities of preschool-aged children who show elevated levels of hyperactivity and oppositional-defiance. It examined the performance of children aged 48 to 67 months on tests of attention/executive function, language, memory, and sensorimotor abilities, as measured by the NEPSY and Conners' K-CPT. Two hundred thirty-seven children were divided into four subgroups based on mothers' report of behavior using rating scales and a diagnostic interview: hyperactive only (HYP), oppositional-defiant only (OD), hyperactive and oppositional-defiant (HYP/OD), and nonproblem. Children in the HYP/OD group scored significantly worse than nonproblem children on four of nine subtests on the NEPSY, including one test of executive function, one test of language comprehension, and both tests of short-term verbal memory. However, only the test of executive function (Statue) showed significant predictive power, and, while specificity of this subtest was good, sensitivity was poor. On the K-CPT, a continuous performance test, children in both the HYP and HYP/OD groups performed worse than children in the OD and nonproblem groups. When the NEPSY Statue subtest and the K-CPT were used together, overall predictive power was .74. Results suggest that neuropsychological deficits can be observed among preschool children with hyperactivity, particularly when comorbid oppositional-defiance is present; however, moderate predictive power suggests that these tests should be used in conjunction with other methods of assessment.  相似文献

We argue that conceptual analyses of collective action should be informed by game-theoretic analyses of collective action. In particular, we argue that Ariel Rubenstein’s so-called ‘Electronic Mail Game’ provides a useful model of collective action, and of the formation of collective intentions.  相似文献

Examined self-handicapping prior to academic-oriented tasks in children with and without ADHD and examined whether stimulant medication influenced self-handicapping. Participants were 61 children ages 6 to 13, including 22 children with ADHD tested after taking a placebo, 21 children with ADHD tested after taking stimulant medication, and 18 non-ADHD controls. Participants completed three measures of self handicapping and also completed self-evaluations of their performance. Results showed greater self handicapping and more positive self-evaluations in children with ADHD than in controls regardless of medication condition. Findings suggest children with ADHD may use self handicapping to ameliorate the effects of experiencing high rates of academic failure.  相似文献
