The association of behavior problems with preschool language disorders has been documented extensively. However, researchers have typically failed to differentiate subgroups of language-impaired children, to use observational data in documenting the behavior disorders, or to study children at the youngest ages. Using a multimodal assessment, this study examined parent-child interaction and behavior problems in a clearly defined subgroup of language-impaired children, those with developmental expressive language disorder (ELD). These children exhibit a delay in expressive language compared with receptive language and nonverbal cognitive skills. Subjects were identified and studied at the youngest age at which the disorder can be assessed. A group of ELD children, averaging 27 months of age, was contrasted with a group of normally developing children, matched for age, sex, and receptive language ability. Groups were compared on observed parent-child interactions as well as maternal responses on the Parenting Stress Index, the Eyberg Child Behavior Inventory, and a behavior-related structured interview. ELD children, when compared with normally developing children, exhibited higher levels of negative behavior and were perceived as different by their parents.Portions of these data were presented at the biennial meeting of the Society for Research in Child Development, Baltimore, April 1987, and at the annual meeting of the Society for Pediatrie Research, Anaheim, California, April 1987.

Galef and his colleagues have repeatedly shown that one rat may transfer information regarding the type of food it has consumed to other conspecifics. Such experiments typically have been conducted in wire-mesh cages or a wooden maze. The present experiments sought to extend this paradigm to the open-field foraging situation having six food patches to choose from. Following interaction with a demonstrator that had consumed either a cocoa or a cinnamon diet, single observers (Experiment 1) were tested in the foraging situation. Food-consumption scores indicated that observers consumed significantly more of their specific demonstrator’s diet than a second diet that was available also. Experiment 2 involved the simultaneous testing of two observers in the foraging laboratory. In Experiment 3 two observers were once again tested, but each had been provided a different food-type message prior to foraging. Positive results, mirroring those of Experiment 1, were obtained in both Experiments 2 and 3. The results of these three experiments underscore the robustness of this phenomenon and its generalizability to other testing conditions.
This study examined how preschool inattention-hyperactivity is related to elementary school reading achievement. Prereading skills were hypothesized to be a link between them. This link was explored using longitudinal data on 105 low-socioeconomic-status (SES) children's inattentive-hyperactive behavior and prereading skills in Head Start and in kindergarten and their inattentive-hyperactive behavior and reading skills in first grade. A model of this relationship was tested using structural equation modeling. The results failed to show a significant path between inattention-hyperactivity and prereading skills at both the Head Start and kindergarten levels. A significant path was found between first grade inattention-hyperactivity and reading skills, confirming that the strong relationship between inattention-hyperactivity and poor reading achievement commonly found in children from other SES levels was also significant in this low-SES sample. Strong relationships were found between pre-reading skills and reading skills, as well as among hyperactivity levels at the three grades. The issue of the direction of the path of influence between attention-behavior and reading achievement is addressed briefly; however, the results indicate that further longitudinal work is necessary to resolve this issue. 相似文献
The position sense of the tongue and aftereffects on the position sense subsequent to loading were directly investigated. Nine subjects judged the straightahead with the tongue before and after straining laterally with the tongue against the horizontal force induced by a 29.5-g weight. Two of these subjects also participated in the experiment after the surface of the tongue had been anesthetized. Prior loading of the tongue biased the subjects' subsequent judgment of the straight-ahead; following loading, the tongue was placed farther in the direction of the previous effort. The results are discussed with reference to postcontraction effects from experiments on loading the limb and eye. 相似文献
Predictions of deficits in children's social problem-solving competencies due to early and continuing father absence were investigated. To test these predictions, equal numbers of father-present and father-absent third graders matched on a number of variables were assessed on measures of social problem-solving performance. In Phase 2 of the study, half of the children from the father-absent category received a 15 week intervention programme which was conducted by adult male trainers to provide structured practice in social problem solving. Results demonstrated that father-absent treatment subjects, compared to father-absent control subjects, improved their social problem-solving skills significantly. Despite improvement due to intervention, social problem-solving scores for father-absent treatment subjects were still below those for father-present control subjects. Educational and developmental implications of the findings were discussed. 相似文献
In this study, the clinical profile of Hindi-speaking stroke patients with aphasia from northern India has been investigated. We examined the interactional effect between age and gender with aphasia type in 97 Hindi-speaking right-handed individuals, the majority of them with a confirmed diagnosis of a cerebrovascular accident. The subjects included in the study ranged from 3 weeks to two years post-onset with a diagnosis of a common classical aphasia (Broca's, Wernicke's, anomic, global, conduction, and transcortical) types involving both males and females. Also examined was the interaction between literacy and aphasia type since the subjects had varied exposures to education (total illiteracy to professional/university education). While the data reported here about Hindi-speaking aphasics are relatively in agreement with the age-aphasia type patterns discussed in western countries, nonetheless some differences were also observed. The mean age of Indian patients with aphasia was significantly lower. Also, in addition to some gender and literacy related differences, an outstanding difference was that many clinical symptoms that are known to co-occur with aphasia were not readily reported by subjects with stroke. 相似文献
The study aimed at determining whether novices to yoga would be able to reduce their heart rate voluntarily and whether the
magnitude of reduction would be more after 30 days of yoga training. Two groups (yoga and control,n=12 each) were assessed on Day 1 and on Day 30. During the intervening 30 days, the yoga group received training in yoga techniques
while the control group carried on with their routine. At each assessment the baseline heart rate was recorded for one minute,
this was followed by a six-minute period during which participants were asked to attempt to voluntarily reduce their heart
rate, using any strategy. Both the baseline heart rate and the lowest heart rate achieved voluntarily during the six-minute
period were significantly lower in the yoga group on Day 30 compared to Day 1 by a group average of 10.7 beats per minute
(i.e., bpm) and 6.8 bpm, respectively (p<.05, Wilcoxon paired signed ranks test). In contrast, there was no significant change in either the baseline heart rate or
the lowest heart rate achieved voluntarily in the control group on Day 30 compared to Day 1. The results suggest that yoga
training can enable practitioners to use their own strategies to reduce the heart rate, which has possible therapeutic applications. 相似文献
A case report is presented providing an account of therapy process and describing the therapist’s reflection on the process
of therapy. It draws attention to the course of building hypothesis and clinical formulation, the core nucleus of any therapy.
The paper highlights the change in therapy goals in different phases of therapy with the introduction of new information.
It also underlines the fact that hypotheses in the formulation need to be constantly updated and checked against the ever
changing information as therapy progresses. The importance of single case design is invaluable in the presentation of therapy
process as it is more closer to clinical practice then group experimental design. Although attention to therapy process issues
is important and there is no dearth of clinical material in India but there are very few published studies reporting therapy
process using single case design. In the present paper, an attempt has been made to provide the account of therapy process
and to share the reflections on the process of building hypothesis & formulation. 相似文献
The present study examines whether valence strength causes relativistic shifts in emotion perception form faces across sleep (filled vs deprived) nights. A group of twelve volunteers participated twice (sleep/no-sleep) with fourteen days gap between participation. Subjects evaluated low valenced facial expressions (targets) in the presence on high valence facial expressions (anchors) before sleep/no sleep nights and again the following morning. Analysis of results using 2?×?2?×?2 (groups, anchor, sessions) split plot analysis of variance suggest that larger relativistic shifts were apparent in the no-sleep group. Also post sleep relativistic shifts in emotion perception were the least (p?0.001). Sleep consolidates emotional memory for faces. 相似文献
