Fathers' face-to-face interactions with their 4-month-old high-risk infants were compared to mothers' interactions with the same infants and to those interactions of fathers and mothers of normal infants. The high-risk infants were less attentive and less affectively responsive than normal infants, and their mothers were more active. Fathers of both high-risk and normal infants engaged in more game playing and laughed more frequently than mothers during interactions. Although the behaviors of the normal and high-risk infants differed, as did the behaviors of mothers interacting with them, the fathers engaged in similar amounts of activity, smiling, laughing and playing games with normal and high-risk infants. Fathers may be less disturbed than mothers by their high-risk infants' lesser responsivity. 相似文献

Examples are given of research on (a) stressful procedures and assessments in the neonatal intensive care nursery and (b) natural caregiving stimulation and self-comforting behaviors that alleviate these stressful experiences. The data from the studies on stressful procedures and assessments revealed that (a) weaning from mechanical ventilation was associated with increased plasma cortisol levels; (b) heelsticks and tube insertions for gavage feedings were accompanied by decreases in oxygen tension (TcPO2); and (c) Brazelton neonatal behavior assessments were followed by increased cortisol levels and decreased growth hormone levels. To alleviate stress, various interventions were tried including caregiver comforting techniques and giving the neonates opportunities to comfort themselves by sucking on pacifiers. The caregiver intervention studies revealed that (a) a simple placement of hands on the head and abdomen of the NICU neonate resulted in a lesser need for oxygen and (b) massaging the NICU neonate resulted in greater weight gain and earlier discharge. In those studies that explored the infant's self-comforting, nonnutritive sucking behavior, the following results emerged: (a) sucking on pacifiers during heelsticks resulted in less crying and lower heart rate and respiration and (b) sucking on pacifiers during tube feedings resulted in smoother bottle feedings later and in greater weight gain. Thus, it appears that several forms of cost-effective interventions can alleviate these stressful procedures and facilitate infant growth and development. 相似文献

Forty-four depressed and non-depressed mothers participated in a videotaped interaction with their own infant and then rated the videotape using the Infant Stereotyping Scale and the Interaction Rating Scale. In addition, one half of the mothers rated a videotape of an unfamiliar infant who was labelled psychologically ‘depressed’ and the other half rated a videotape of the same infant with no label given. Both the depressed and non-depressed mothers rated the ‘depressed’ labelled infant more negatively than the non-labelled infant on the attributes of physical potency, cognitive competence, sociability and difficult behaviour. Physical appearance was the only rating that was not biased by the ‘depressed’ label. Mothers' ratings of their own infants were more positive than their ratings of the non-labelled stimulus infant. Depressed mothers did not see their infants more negatively except on one rating. They rated the physical appearance of their own infant more negatively than non-depressed mothers. 相似文献

To determine whether infants of “depressed” mothers interact better with their nondepressed fathers, twenty-six 3- to 6-month-old infants were videotaped during face-to-face interactions with their parents. The “depressed” mother group consisted of twelve 3- to 6-month-old infants and their “depressed” mothers and nondepressed fathers. The control group was composed of 14 nondepressed mothers and nondepressed fathers and their 3- to 6-month-old infants. In the “depressed” mother group, the nondepressed fathers received better interaction ratings than the “depressed” mothers. In turn, the infants received better interaction ratings when they interacted with their nondepressed fathers than with their “depressed” mothers. In contrast, nondepressed fathers and mothers and their infants in the control group did not differ on any of their interaction ratings. These findings suggest that infants' difficult interaction behaviors noted during interactions with their “depressed” mothers may not extend to their nondepressed fathers. The data are discussed with respect to the notion that nondepressed fathers may “buffer” the effects of maternal depression on infant interaction behavior. 相似文献

In the present study, 31 of 89 adolescents responded affirmatively to the following statement: "Sometimes I get so angry that I worry I will become violent." These adolescents (the anger group) were compared with the nonanger group, and several differences were found. The anger group (1) reported less intimacy with parents, received less support from them, and was less close to siblings; (2) had more opposite-sex friends, dated more frequently, and more frequently had a boyfriend or girlfriend; (3) had a lower grade point average; (4) were more depressed; and (5) used marijuana more frequently. Results of a regression analysis revealed that depression and dating were the only significant predictors of anger, explaining 17% of the variance. 相似文献

One conceptualization of meta-analysis is that studies within the meta-analysis are sampled from populations with mean effect sizes that vary (random-effects models). The consequences of not applying such models and the comparison of different methods have been hotly debated. A Monte Carlo study compared the efficacy of Hedges and Vevea's random-effects methods of meta-analysis with Hunter and Schmidt's, over a wide range of conditions, as the variability in population correlations increases. (a) The Hunter-Schmidt method produced estimates of the average correlation with the least error, although estimates from both methods were very accurate; (b) confidence intervals from Hunter and Schmidt's method were always slightly too narrow but became more accurate than those from Hedges and Vevea's method as the number of studies included in the meta-analysis, the size of the true correlation, and the variability of correlations increased; and (c) the study weights did not explain the differences between the methods. 相似文献

The paper offers a solution to the semantic paradoxes, one in which (1) we keep the unrestricted truth schema True(A)A, and (2) the object language can include its own metalanguage. Because of the first feature, classical logic must be restricted, but full classical reasoning applies in ordinary contexts, including standard set theory. The more general logic that replaces classical logic includes a principle of substitutivity of equivalents, which with the truth schema leads to the general intersubstitutivity of True(A) with A within the language.The logic is also shown to have the resources required to represent the way in which sentences (like the Liar sentence and the Curry sentence) that lead to paradox in classical logic are defective. We can in fact define a hierarchy of defectiveness predicates within the language. Contrary to claims that any solution to the paradoxes just breeds further paradoxes (revenge problems) involving defectiveness predicates, there is a general consistency/conservativeness proof that shows that talk of truth and the various levels of defectiveness can all be made coherent together within a single object language. 相似文献

Seventy-nine high school seniors were administered the Center for Epidemiological Studies Depression Scale (CES-D), as well as a questionnaire on parent relationships, peer relationships, positive and negative feelings including suicidal thoughts, and lifestyle variables including academic performance, exercise, and drug use. The group of adolescents who scored above the clinical cutoff for depression on the CES-D (n = 29) had poorer relations with parents. Further, the incidence of paternal depression in that group was greater. The depressed adolescents also had less optimal peer relationships, fewer friends, and were less popular. They experienced less happiness and more frequent suicidal thoughts. They spent less time doing homework, had a lower grade point average, and spent less time exercising. The depressed group also reported more use of marijuana and cocaine. A stepwise regression indicated that physical affection with parents, homework, well-being, exercise, happiness, and parent relations explained 55% of the variance. 相似文献

At 6 months following the death of their spouse, 37 participants reported their grief-related symptoms and thoughts, and then, approximately 4.5 years later, they attempted to recall how they felt at the time of the 6-month report. Although participants were far less distressed at recall than initially, they recalled their 6-month grief rather accurately. Participants did however overestimate prior grief-related intrusive ideation. Participant's current level of grief predicted what they recalled slightly better than the actual initial grief. Conversely, what they recalled predicted current levels of grief across various measures. Participants whose grief diminished relatively little over time tended to overestimate prior grief more. The retrospective reappraisal that one's past grief was not severe may indicate effective coping. 相似文献
