This study investigated the sleep/wake states, respiration, and affective behaviors of premature infants who were provided à “breathing” bear in the isolette from 33 to 35 weeks conceptional age (CA). The Breathing Bear is à source of rhythmic stimulation that is optional for the infants. Its “breathing” reflects the breathing rate of the individual infant. At 33 weeks CA, 27 premature infants were provided à Breathing Bear (BrBr) and 26 were given à Non-Breathing Bear (N-BrBr). At 35 weeks, interfeed observations for an average of 1.7 hours were made of the babies' states and state-specific behaviors, along with respiration recordings. By 35 weeks, the BrBr babies showed less wakefulness, more quiet sleep, fewer startles in quiet sleep, and less crying than the N-BrBr babies. In addition, they were more likely to smile and N-BrBr babies were more likely to grimace in active sleep. These findings replicate and extend previous reports of effects of the Breathing Bear on neurobehavioral organization. They also suggest that less negative affect is expressed by the BrBr babies; and they point to the importance of future study of preterm infants' affective expressions, both in sleep and in waking. 相似文献

Hippocampal damage and exploratory preferences in rats: memory for objects, places, and contexts 总被引:8,自引:1,他引:7 下载免费PDF全文

Rats have a natural tendency to spend more time exploring novel objects than familiar objects, and this preference can be used as an index of object recognition. Rats also show an exploratory preference for objects in locations where they have not previously encountered objects (an index of place memory) and for familiar objects in contexts different from those in which the objects were originally encountered (an index of context memory). In this experiment, rats with cytotoxic lesions of the hippocampal formation were tested on all three versions of the novelty-preference paradigm, with a 5-min retention interval between the familiarization and test phases. Rats with sham lesions displayed a novelty preference on all three trial types, whereas the rats with hippocampal lesions displayed a novelty preference on Object trials but did not discriminate between the objects on Place trials or Context trials. The findings indicate that hippocampal damage impairs memory for contextual or spatial aspects of an experience, whereas memory for objects that were part of the same experience are left relatively intact. 相似文献

Psychosocial Treatment Strategies in the MTA Study: Rationale, Methods, and Critical Issues in Design and Implementation 总被引:5,自引:0,他引:5
Wells KC Pelham WE Kotkin RA Hoza B Abikoff HB Abramowitz A Arnold LE Cantwell DP Conners CK Del Carmen R Elliott G Greenhill LL Hechtman L Hibbs E Hinshaw SP Jensen PS March JS Swanson JM Schiller E 《Journal of abnormal child psychology》2000,28(6):483-505
The Collaborative Multimodal Treatment Study of Children with Attention Deficit Hyperactivity Disorder (ADHD), the MTA, is the first multisite, cooperative agreement treatment study of children, and the largest psychiatric/psychological treatment trial ever conducted by the National Institute of Mental Health. It examines the effectiveness of Medication vs. Psychosocial treatment vs. their combination for treatment of ADHD and compares these experimental arms to each other and to routine community care. In a parallel group design, 579 (male and female) ADHD children, aged 7–9 years, 11 months, were randomly assigned to one of the four experimental arms, and then received 14 months of prescribed treatment (or community care) with periodic reassessments. After delineating the theoretical and empirical rationales for Psychosocial treatment of ADHD, we describe the MTA's Psychosocial Treatment strategy applied to all children in two of the four experimental arms (Psychosocial treatment alone; Combined treatment). Psychosocial treatment consisted of three major components: a Parent Training component, a two-part School Intervention component, and a child treatment component anchored in an intensive Summer Treatment Program. Components were selected based on evidence of treatment efficacy and because they address comprehensive symptom targets, settings, comorbidities, and functional domains. We delineate key conceptual and logistical issues faced by clinical researchers in design and implementation of Psychosocial research with examples of how these issues were addressed in the MTA study.Deceased 相似文献

Parenting and family stress treatment outcomes in the MTA study were examined. Male and female (579), 7–9-year-old children with combined type Attention Deficit Hyperactivity Disorder (ADHD), were recruited at six sites around the United States and Canada, and randomly assigned to one of four groups: intensive, multi-faceted behavior therapy program alone (Beh); carefully titrated and monitored medication management strategy alone (MedMgt); a well-integrated combination of the two (Comb); or a community comparison group (CC). Treatment occurred over 14 months, and assessments were taken at baseline, 3, 9, and 14 months. Parenting behavior and family stress were assessed using parent-report and child-report inventories. Results showed that Beh alone, MedMgt alone, and Comb produced significantly greater decreases in a parent-rated measure of negative parenting, Negative/Ineffective Discipline, than did standard community treatment. The three MTA treatments did not differ significantly from each other on this domain. No differences were noted among the four groups on positive parenting or on family stress variables. Results are discussed in terms of the theoretical and empirically documented importance of negative parenting in the symptoms, comorbidities and long-term outcomes of ADHD. 相似文献

The measurement of “switch costs” is held to be of interest because, as is widely believed, they may reflect the control
processes that are engaged when subjects switch between two (or more) competing tasks. [In task-switching experiments, the
reaction time (RT) switch cost is typically measured as the difference in RT between switch and non-switch (repeat) trials.]
In this report we focus on the RT switch costs that remain even after the subject has had some time to prepare for the shift
of task, when the switch cost may be approximately asymptotic (so-called residual switch costs). Three experiments are presented.
All three experiments used Stroop colour/word, and neutral stimuli. Participants performed the two tasks of word-reading and
colour-naming in a regular, double alternation, using the “alternating runs” paradigm (R. D. Rogers & S. Monsell, 1995). The
experiments were designed to test the hypothesis that RT switch costs depend on a form of proactive interference (PI) arising
from the performance of a prior, competing task. A. Allport, E. A. Styles and S. Hsieh (1994) suggested that these PI effects
resulted from “task-set inertia”, that is, the persisting activation-suppression of competing task-sets, or competing task-processing
pathways. The results confirmed the existence of long-lasting PI from the competing task as a major contributor to switch
costs. Non-switch trials, used as the baseline in the measurement of switch costs, were also shown to be strongly affected
by similar PI effects. However, task-set inertia was not sufficient to account for these results. The results appeared inconsistent
also with all other previous models of task switching. A new hypothesis to explain these between-task interference effects
was developed, based on the stimulus-triggered retrieval of competing stimulus-response (S-R) associations, acquired (or strengthened)
in earlier trials. Consistent with this retrieval hypothesis, switch costs were shown to depend primarily on the S-R characteristics
of the preceding task (the task that was switched from) rather than the upcoming task. Further, the effects of the other,
competing task were found to persist over many successive switching trials, affecting switch costs long after the stimulus
overlap (and hence the principal S-R competition) between the current tasks had been removed. Switch costs were also found
to be affected by recent, item-specific experience with a given stimulus, in either the same or the competing task. Finally,
the results showed that switch costs were massively affected by the ratio of the number of prior trials, in response to the
same stimuli, that had implemented either the currently intended or the competing S-R mappings. None of these effects are
predicted by current models of residual switch costs, which appeal to the differences in control processes assumed to be engaged
in switch versus non-switch trials.
