The present study investigated the impact of sleep deprivation on several aspects of affective functioning in healthy participants selected from three different developmental periods: early adolescence (ages 10-13), midadolescence (ages 13-16), and adulthood (ages 30-60). Participants completed an affective functioning battery under conditions of sleep deprivation (a maximum of 6.5 hours total sleep time on the first night followed by a maximum of 2 hours total sleep time on the second night) and rest (approximately 7-8 hours total sleep time each night for two consecutive nights). Less positive affect was observed in the sleep-deprived, compared to rested, condition. This effect held for 9 of the 12 positive affect items on the PANAS-C. Participants also reported a greater increase in anxiety during a catastrophizing task and rated the likelihood of potential catastrophes as higher when sleep deprived, relative to when rested. Early adolescents appraised their main worry as more threatening when sleep deprived, relative to when rested. These results support and extend previous research underscoring the adverse affective consequences of sleep deprivation. 相似文献

The present research examined the extent to which interpersonal concerns about rejection based on appearance, or Appearance-based Rejection Sensitivity (Appearance-RS), serves as an indicator of risk for excessive body image concerns. Extending previous research, we examined the association between Appearance-RS and symptoms of body dysmorphic disorder (BDD) and cosmetic surgery attitudes among 106 British university students. Consistent with predictions, Appearance-RS uniquely predicted greater degree of BDD symptoms after controlling for other known predictor variables. Also, as expected, Appearance-RS uniquely predicted acceptance of cosmetic surgery for both intrapersonal and social reasons and greater consideration of having cosmetic surgery in the future. These findings highlight the importance of assessing individuals’ sensitivity to rejection from others based on their physical appearance in investigations of excessive body image concerns. 相似文献

Recent research has identified mothers' mental reflective functioning and verbal mind‐minded comments as important predictors of subsequent infant attachment security. In the present study, we examine associations between mothers' (N = 95) parenting reflectivity expressed in an interview and observed parenting behavior, including verbal mind‐minded comments and interactive behavior during interaction with their 7‐month‐old infants. Parenting reflectivity was coded from the Working Model of the Child Interview. Maternal behavior was assessed via observations of mother–infant interaction during free play and structured teaching tasks. Both maternal appropriate mind‐minded comments as well as other indicators of maternal interactive behavior were coded. Parenting reflectivity was positively correlated with mind‐minded comments and behavioral sensitivity. Hierarchical multiple regression analyses indicated that parenting reflectivity contributed to maternal behavior beyond the contributions of mothers' educational status and depression symptoms. Discussion emphasizes the importance of individual differences in parental capacity to accurately perceive and mentalize their infants' experience, and the consequences of these differences for caregiving behavior. 相似文献

The present study evaluated the interactive behavior of three groups of mothers and their 3-month-old infants in the Face-to-Face Still-Face paradigm. The mothers had either a clinical diagnosis of major depressive disorder (MDD, n = 33) with no comorbidity, a clinical diagnosis of panic disorder (PD, n = 13) with no comorbidity, or no clinical diagnosis (n = 48). The sample was selected to be at otherwise low social and medical risk, and all mothers with PD or MDD were in treatment. The findings indicated that (a) infants of mothers with PD or MDD displayed the traditional still-face and reunion effects described in previous research with nonclinical samples; (b) the 3-month-old infants in this study showed similar, but not identical, gender effects to those described for older infants; and (c) there were no patterns of maternal or infant interactive behavior that were unique to the PD, MDD, or control groups. These results are discussed in light of mothers' risk status, receipt of treatment, severity of illness, and comorbidity of PD and MDD. 相似文献

This article examines the philosophy that Osman bin Bakar has published in English. Beginning with his biography and theoretical groundings, and especially the influences that Greek, Chinese, Indian, and Islamic philosophers have had on his thought, the article then turns to Bakar's philosophy of science, ‘ilm al‐tawhīd, how knowledge about the world should be classified, and especially evolutionary theory within Islamic philosophy. These developments in philosophical grounding provide Bakar with a platform to suggest how science can be used as a vehicle for inter‐civilizational dialogue. 相似文献

Although materials informing parents about children’s mental health (CMH) problems can improve outcomes, we know relatively
little about the design factors that might influence their utilization of available resources. We used a discrete choice conjoint
experiment to model the information preferences of parents seeking mental health services for 6 to 18 year olds. Parents completed
30 choice tasks presenting experimentally varied combinations of 20 four-level CMH information content, transfer process,
and outcome attributes. Latent class analysis revealed three segments with different preferences. Parents in the Action segment
(43%) chose materials providing step-by-step solutions to behavioral or emotional problems. They preferred weekly meetings
with other parents and coaching calls from a therapist. The Information segment (41%) chose materials helping them understand
rather than solve their child’s problems. These parents were more sensitive to logistical factors such as receiving information
in groups, the location where information was available, the modality in which the information was presented, and the time
required to obtain and use the information. The Overwhelmed segment (16%) reported more oppositional and conduct problems,
felt their children’s difficulties exerted a greater adverse impact on family functioning, and reported higher personal depression
scores than those in the Action or Information segments. Nonetheless, they did not choose information about, or solutions
to, the problems their children presented. Simulations predicted that maximizing utilization and realizing the potential benefits
of CMH information would require knowledge transfer strategies consistent with each segment’s preferences.

Types of Aggression,Responsiveness to Provocation,and Callous-unemotional Traits in Detained Adolescents 总被引:1,自引:1,他引:0
The present study investigated differences in the behavioral and psychophysiological responses to provocation and in the level of callous-unemotional traits in boys exhibiting different patterns of aggression. Eighty-five boys (ages 13-18) in a juvenile detention center played a competitive computer task against a hypothetical peer who provided low and high levels of provocation. Youth high on both self-reported reactive and proactive aggression showed different behavioral responses to provocation than youth high on only reactive aggression. Specifically, the combined group showed high levels of aggressive responses without any provocation, whereas the group high on reactive aggression showed an increase in aggressive responding to low provocation. Further, results revealed a trend for the combined group to show lower levels of skin conductance reactivity to low provocation if they were also high on callous-unemotional traits. 相似文献

Despite considerable research on language production errors involving speech, little research exists in the complementary domain of writing. Two experiments investigated the production of homophone substitution errors, which occur when a contextually appropriate word (e.g., beech) is replaced with its homophone (e.g., beach tree). Participants wrote down auditorily presented sentences containing dominant or subordinate homophones. Homophones were preceded by a lexical prime that overlapped in phonology and orthography (e.g., teacher) or only orthography (e.g., headmaster) with the target homophone. Results showed more substitution errors when the context elicited a subordinate homophone than when it elicited a dominant homophone. Furthermore, both types of primes equivalently increased production of homophone errors relative to control words (e.g., lawyer), suggesting that only orthographic overlap between the prime and target was necessary to influence errors. These results are explained within dual-route models of spelling, which postulate an interaction between lexical and sublexical routes when spelling. 相似文献

Cognitive theories of depression posit that automatically activated cognitive schemas, including negative thoughts about the self and the future, predispose individuals to develop depressive disorders. However, prior research has largely examined these constructs using explicit tests in currently depressed individuals. Using the Implicit Association Test (IAT), the present study examined automatic associations between the self and mood state ("depression IAT") and between the future and mood state ("hopelessness IAT") before and after a negative mood induction in 19 remitted depressed individuals and 23 healthy controls. In the depression IAT, remitted depressed participants exhibited an overall lower tendency to associate themselves with happiness relative to the healthy controls before the mood induction. Control, but not remitted depressed, participants' automatic associations between the self and happiness diminished following the mood induction. Contrary to our hypotheses, no significant findings emerged when considering the hopelessness IAT. Consistent with prior studies, no significant correlations emerged between implicit and explicit biases, suggesting that these measures probe different processes. Results extend prior IAT research by documenting the presence of a reduced tendency to associate the self with happiness in a sample at increased risk for depression. 相似文献

In this study, the authors investigated the degree to which a family investment model would help account for the association between family of origin socioeconomic characteristics and the later educational attainment of 451 young adults (age 26) from 2-parent families. Parents' educational level, occupational prestige, and family income in 1989 each had a statistically significant direct relationship with youths' educational attainment in 2002. Consistent with the theoretical model guiding the study, parents' educational level and family income also demonstrated statistically significant indirect effects on later educational attainment through their associations with growth trajectories for supportive parenting, sibling relations, and adolescent academic engagement. Supportive parenting and sibling relations were linked to later educational attainment through their association with adolescent academic engagement. Academic engagement during adolescence was associated with educational attainment in young adulthood. These basic processes operated similarly regardless of youths' gender, target youths' age relative to a near-age sibling, gender composition of the sibling dyad, or gender of parent. 相似文献
