Recent findings of dissociations between direct and indirect tests of memory and perception have renewed enthusiasm for the study of unconscious processing. The authors argue that such findings are heir to the same problems of interpretation as are earlier evidence of unconscious influences--namely, one cannot eliminate the possibility that conscious processes contaminated the measure of unconscious processes. To solve this problem, the authors define unconscious influences in terms of lack of conscious control and then describe a process dissociation procedure that yields separate quantitative estimates of the concurrent contributions of unconscious and consciously controlled processing to task performance. This technique allows one to go beyond demonstrating the existence of unconscious processes to examine factors that determine their magnitude. 相似文献

Acute stress stimulates the expression and release of corticotropin-releasing hormone (CRH) and arginine vasopressin (AVP) from the hypothalamus, and the pro-opiomelanocortin products beta-endorphin and ACTH from the anterior pituitary. These neuropeptides are also expressed in immune tissues, and it has been proposed that they may modulate immune responses to stress through paracrine mechanisms. We subjected rats to restraint stress or central injection of interleukin (IL)-1beta to determine whether these acute stimuli can alter the expression of neuropeptides in the spleen and thymus. Restraint stress significantly increased the contents of all these neuropeptides in thymic, but not splenic, extracts. A single icv injection of IL-1beta increased contents of CRH, AVP, ACTH and beta-endorphin in the spleens of both sham-operated and adrenalectomised (ADX) rats. IL-1beta increased thymic contents of CRH and ACTH in sham-operated rats but these increases were not observed in ADX rats. These results suggest that the effects of IL-1beta on neuropeptide expression in the spleen are independent of glucocorticoids, whereas IL-1beta stimulation of neuropeptide expression in the thymus is dependent on circulating glucocorticoids. There were significant correlations between increases in CRH, ACTH and beta-endorphin in the spleen, and between CRH and ACTH in the thymus, consistent with the suggestion that IL-1beta-induced increases in ACTH and beta-endorphin may be mediated through CRH. These results provide evidence that stressors can directly influence neuropeptide expression in immune tissues. Thus stress may influence immune functions through paracrine mechanisms involving locally synthesised neuropeptides as well as through activation of the hypothalamo-pituitary-adrenal axis. 相似文献

The health of clergy is important, and clergy may find health programming tailored to them more effective. Little is known
about existing clergy health programs. We contacted Protestant denominational headquarters and searched academic databases
and the Internet. We identified 56 clergy health programs and categorized them into prevention and personal enrichment; counseling;
marriage and family enrichment; peer support; congregational health; congregational effectiveness; denominational enrichment;
insurance/strategic pension plans; and referral-based programs. Only 13 of the programs engaged in outcomes evaluation. Using
the Socioecological Framework, we found that many programs support individual-level and institutional-level changes, but few
programs support congregational-level changes. Outcome evaluation strategies and a central repository for information on clergy
health programs are needed. 相似文献

Direct and indirect relations among maternal depression, maternal Expressed Emotion (EE: Self- and Child-Criticism), child internalizing and externalizing symptoms, and child attachment were examined. Participants were mothers with depression (n?=?130) and comparison mothers (n?=?68) and their toddlers (M age?=?20 mo.; 53% male). Assessments included the Diagnostic Interview Schedule (maternal depression); the Five Minute Speech Sample (EE); the Child Behavior Checklist (toddler behavior problems); the Strange Situation (child attachment). Direct relations were significant linking: 1) maternal depression with both EE and child functioning; 2) Child-Criticism with child internalizing and externalizing symptoms; 3) Self-Criticism with child attachment. Significant indirect relations were found linking maternal depression with: 1) child externalizing behaviors via Child-Criticism; 2) child internalizing behaviors via Self- and Child-Criticism; and 3) child attachment via Self-Criticism. Findings are consistent with a conceptual model in which maternal EE mediates relations between maternal depression and toddler socio-emotional functioning. 相似文献

Research has shown that repeated statements are rated as more credible than new statements. However, little research has examined whether such "illusions of truth" can be produced by contextual (nonmnemonic) influences, or compared to the magnitude of these illusions in younger and older adults. In two experiments, we examined how manipulations of perceptual and conceptual fluency influenced truth and familiarity ratings made by young and older adults. Stimuli were claims about companies or products varying in normative familiarity. Results showed only small effects of perceptual fluency on rated truth or familiarity. In contrast, manipulating conceptual fluency via semantic/textual context had much larger effects on rated truth and familiarity, with the effects modulated by normative company familiarity such that fluency biases were larger for lesser-known companies. In both experiments, young and older adults were equally susceptible to fluency-based biases. 相似文献

Mother-child play of maltreating and nonmaltreating families was analyzed when infants were 12 months old (Time 1), and 2 years old (Time 2), as a context to examine children's developing cognitive and social skills. At Time 1, infants from abusing families demonstrated less independent and more imitative behavior during play than did infants from neglecting and nonmaltreating families, suggesting a delay in emerging social behaviors. In this longitudinal follow-up, mother-child play was reassessed 1 year later (N = 78), with a focus on children's engagement in nonplay and pretend play and on children's abilities to initiate social exchanges and respond to parental requests. Play and social behavior were coded from semistructured and unstructured play paradigms at both time points. Maternal attention-directing behavior and limit setting also was assessed. At Time 2, children from abusing, neglecting, and nonmaltreating families did not differ in cognitive play complexity. However, children from abusing families engaged in less child-initiated play than did children from neglecting and nonmaltreating families, demonstrating less socially competent behavior. Longitudinal analyses revealed child initiated play at Time 2 was negatively associated with abuse and with maternal physical attention directing behavior at Time 1. Child negative reactivity at Time 2 was positively associated with Time 1 maternal physical behavior and child imitation and with Time 2 maternal controlling behavior. Implications for early intervention efforts are emphasized. 相似文献

The efficacy of Toddler-Parent Psychotherapy (TPP) as a preventive intervention for fostering cognitive development in the offspring of depressed mothers was evaluated. Mothers with major depressive disorder and their toddlers were randomly assigned to TPP (n = 43) or to a nonintervention group (n = 54) and compared to a control group (n = 61) of women with no current or past mental disorder. At baseline (age 20 months), the groups did not differ on the Bayley Mental Development Index. At post-intervention follow-up (age 3 years), a relative decline in IQ was found in the depressed nonintervention group, whereas the depressed intervention and the normal control groups continued to be equivalent, with higher WPPSI-R Full Scale and Verbal IQs. The worst outcome was found among nonintervention children whose mothers had subsequent depressive episodes. The results confirm the developmental risks faced by offspring of depressed mothers and support the efficacy of the preventive intervention in safeguarding successful cognitive development in at-risk youngsters. 相似文献

Research on recognition memory using the process dissociation procedure has suggested that although recollection (R) declines with age, familiarity (F) remains age invariant. However, this research has used relatively broad definitions of R. An important question concerns age-related changes in memory when R is defined in terms of specific event details. Yonelinas and Jacoby (1996a) required young participants to recollect specific, criterial details of a prior event and found evidence that recollection of noncriterial details elevated estimates of F yet still operated automatically. In the present study, the issue of noncriterial recollection was examined in the context of aging. The results replicated the effects of noncriterial recollection for the young, but not for the older adults, who also showed overall reduced levels of familiarity. 相似文献
