Sixty-eight preterm infants (M GA = 30 weeks) were randomly assigned to a moderate or to a light pressure massage therapy group to receive 15 massages three times per day for 5 days. Behavior state, stress behaviors and heart rate were recorded for 15 min before and during the first 15-min therapy session. Weight gain was recorded over the 5-day therapy period. The moderate versus light pressure massage group gained significantly more weight per day. During the behavior observations the moderate versus light pressure massage group showed significantly lower increases from the pre-session to the session recording on: (1) active sleep; (2) fussing; (3) crying; (4) movement; and (5) stress behavior (hiccupping). They also showed a smaller decrease in deep sleep, a greater decrease in heart rate and a greater increase in vagal tone. Thus, the moderate pressure massage therapy group appeared to be more relaxed and less aroused than the light pressure massage group which may have contributed to the greater weight gain of the moderate pressure massage therapy group.  相似文献

A recent survey was conducted on stimulation of mothers and babies during pregnancy and the neonatal period. The survey was responded to by 82 neonatology staff members from Neonatal Intensive Care Units (NICUs) at hospitals in the United States. Some forms of stimulation were extremely common including (1) skin-to-skin following birth in the delivery room (83% of hospitals); (2) containment (swaddling and surrounded by blanket rolls) in the NICU (86%); (3) music in the NICU (72%); (4) rocking in the NICU (85%); (5) kangaroo care (98%); (6) non-nutritive sucking during tubefeedings in the NICU (96%); and (7) breastfeeding in the NICU (100%). Other forms of stimulation occurred less frequently including (1) pregnancy massage (19%); (2) labor massage (30%); (3) the Doula (assistant who comforts during labor and delivery) (30%); (4) waterbeds in the NICU (23%); and (5) preterm infant massage in the NICU (38%).  相似文献

In this study, the authors examined the stability of Minnesota Multiphasic Personality Inventory--2 (J. N. Butcher, W. G. Dahlstrom, J. R. Graham, A. Tellegen, & B. Kaemmer, 1989) code types in a sample of 94 injured workers with a mean test-retest interval of 21.3 months (SD = 14.1). Congruence rates for undefined code types were 34% for high-point codes, 22% for 2-point codes, and 22% for 3-point codes. The data provide tentative evidence suggesting that defined code types are more stable than undefined code types. Cohen's kappa, a statistic that controls for chance agreement, was calculated for each clinical scale for both 2-point and 3-point code types. Only 2 of the 20 kappa coefficients were not significant at the p = .05 level.  相似文献

Changes in reward magnitude or value have been reported to produce effects on timing behavior, which have been attributed to changes in the speed of an internal pacemaker in some instances and to attentional factors in other cases. The present experiments therefore aimed to clarify the effects of reward magnitude on timing processes. In Experiment 1, rats were trained to discriminate a short (2 s) vs. a long (8 s) signal followed by testing with intermediate durations. Then, the reward on short or long trials was increased from 1 to 4 pellets in separate groups. Experiment 2 measured the effect of different reward magnitudes associated with the short vs. long signals throughout training. Finally, Experiment 3 controlled for satiety effects during the reward magnitude manipulation phase. A general flattening of the psychophysical function was evident in all three experiments, suggesting that unequal reward magnitudes may disrupt attention to duration.  相似文献

To examine the impact of early linguistic experiences on later verbal report of autobiographical memory, 13 hearing adults and 13 deaf adults born to hearing parents described events that occurred before and after the age of 10 years. The contextual, temporal, and thematic coherence of the narratives was rated. The use of emotional, perceptual, mental, and physiological states was also recorded. There were differences in the coherence of the narratives and use of internal states according to the age at which the events occurred. There were no group differences in coherence, but hearing adults provided longer narratives than deaf adults. When narrative length was controlled, deaf adults included more emotional states than hearing adults. Results suggest that early unavailability of language does not impact the coherence of adults’ narratives, although certain features of linguistic expression specific to ASL may result in greater saturation of emotional states references in autobiographical narratives of deaf adults.  相似文献

The purpose of this article is threefold: (a) to describe the relevant ethical and legal issues associated with decisional capacity among minors and to discuss the importance of these concepts for children and adolescents living with HIV, (b) to provide a framework for assessing the decisional capacity of children and adolescents with HIV, and (c) to present a model for thinking about how to use this assessment data to guide action along the protection-autonomy continuum.  相似文献

In the study of spirituality and forgiveness, researchers have begun to look at how dynamic spiritual experiences influence forgiveness. In three studies, we develop the Relational Engagement of the Sacred for a Transgression (REST) Scale, which assesses the extent to which victims actively engage a relationship with the Sacred to deal with a specific transgression. In Study 1, exploratory factor analysis was used to determine the factor structure of the REST. In Study 2, the factor structure was replicated using confirmatory factory analysis. The REST was correlated with religious commitment and negatively related to avoidant attachment to God. In Study 3, evidence supporting the scale's construct validity was adduced. REST scores were correlated with other appraisals of relational spirituality. Structural equation modeling was used to compare theoretical models. REST scores were related to dedication to the Sacred and viewing the transgression as a desecration. In addition, REST scores were positively related to empathy, which was positively related to forgiveness. Furthermore, REST scores predicted forgiveness above and beyond other appraisals of relational spirituality.  相似文献

Tarski's correspondence theory of truth (which he spells out in his semantic conception of truth) is open to two interpretations. This ambiguity in the theory has led philosophers to find support in it for metaphysical reali sm. In fact, Tarski's theory turns out to support a form of ontological relativism. In different passages Tarski himself gives support to each of these interpretations. The first interpretation leads to ontological relativism, while the second sacrifices the connection between language and the world. I clarify the dilemma that I see in having to choose between these two interpretations, explain how these interpretations have their source in different problems which occupied Tarski, and consider a possible solution to the dilemma. Finally, finding good reasons to claim that Tarski's theory is indeed a correspondence theory of truth, I argue in favour of the first interpretation with its relativistic implications.  相似文献

Although toddlers are clearly capable of interacting with peers, the amount and type of interactions among toddlers is controversial. Objectives of the present study were (a) to determine the effect of dyad versus group settings on the amount and type of social behaviors with peers, (b) to determine preference for interacting with peers versus adults, and (c) to determine differences in the types of behaviors directed to peers and adults. Sixteen children (with a mean age of 27 months) were observed in both a group setting and a dyad setting; their mothers were present in both settings. The children were from three different toddler classes, each meeting once a week. Specific social behaviors were coded, as well as the person to whom the behavior was directed (i.e., peer or adult). Setting affected toddlers' behaviors with adults but not behaviors with peers. Regardless of setting, toddlers preferred interacting with adults. The types of behaviors directed to peers and adults differed. Direct interactions with peers were rare, but interest and awareness of peers was shown by moderately high levels of proximity and parallel play. The use of different criteria to define social play appears to account for differences across studies in the amount of peer interaction.  相似文献

One of the essential questions regarding movement deficits in Parkinson's disease (PD) is whether they stem from impaired selecting and switching among movements, impaired use of predictive information to prepare movement, or impaired execution of movement. PD subjects (n = 9) and age-matched control subjects (n = 8) performed a cued, sequential-response RT task. The cue provided either no information, accurate information, or inaccurate information about the upcoming response. PD subjects used predictive information to prepare and to switch among movement sequences normally, but second and third key press latencies were prolonged in comparison with the first key press latency. In Experiments 2 and 3, the effects of choice set and sequence length on key press latencies were examined. These results provide evidence that PD subjects initiate movement before the entire response sequence is prepared. PD does not impair motor programming or execution processes themselves but impairs the smooth coordination of those processes.  相似文献
