Children of two different age groups, 2-year-olds and 4-year-olds, were placed with male and female adults in a laboratory play situation where the children were forced to control the choice of toys and mode of interaction. The 4-year-old children elicited different types of play behaviors from male and female adults, while the younger children did not.Final preparations of this paper was completed on a post-doctoral fellowship (Grant No. 1 T32MH 16955-01) at Oregon Social Learning Center. The study with older children was presented at the biennial conference of the Society for Research in Child Development, San Francisco, March 1979.  相似文献

This paper asserts that, contrary to the beliefs of many clinicians, patients with bipolar affective disorder often experience a deteriorating course characterized by pervasive social dysfunction. It reviews the literature, identifying a rationale for group psychotherapy as an adjunct to medication in the management of these chronic patients. It outlines a theoretical approach to bipolar group therapy, and presents a retrospective study comparing the course of 43 lithium-treated bipolar patients before and after entering bipolar groups. During the year in group therapy, bipolar patients displayed significant improvements in symptom relief as well as social functioning. It is proposed that group process enhances treatment with medication, providing benefits not evident with medication alone.  相似文献

In our judgment, the Apple II/FIRST system (Scandrett & Gormezano, 1980) is an efficient and versatile system for experimental control and data acquisition in classical conditioning experiments. However, these attributes would be of limited value if the system did not extract measures from our analog signals with a high degree of correspondence with our ruler measurement procedures. Accordingly, we determined the system’s validity in extracting measures of CR occurrence and CR latency in three conditioning experiments. Pearson productmoment correlation coefficients indicated a very satisfactory degree of agreement on measurements made by the Apple II/FIRST system and ruler. Moreover, intraclass correlations and analysis of variance procedures applied to percent CRs and CR latency revealed several small, but divergent, differences between ruler and computer measurement of CR latency across the three experiments. However, subsequent analyses of variance revealed that the number and pattern of significant sources of variation for ruler or computer measurements were virtually identical. Accordingly, we have concluded that our system can successfully replace our traditional method of ruler measurement.  相似文献

Two experiments were conducted to test the encoding-specificity hypothesis. In Experiment 1, subjects were presented pairs of coordinates to study, followed by a cued-recall test. Semantically weak and strong coordinates (defined by the degree of featural overlap shared with the pairs) served as encoding and retrieval cues. The semantic strength of the retrieval cue proved to be the most important factor in recall, whereas the re-presentation of an unrelated cue previously seen during encoding led to no facilitation of recall. In Experiment 2, three noun coordinates of varied semantic interrelatedness were presented for study and then were cued for recall by novel semantically strong or weak coordinates. Maximum recall was achieved when a strong encoding condition was matched with a strong retrieval cue. Implications of these findings for an encoding-specificity hypothesis were discussed.  相似文献

Three experiments were conducted to examine the theoretical prediction that the intensity of sadness is determined not only by the instigating event but also by factors that impede or deter the function or purpose of sadness. In the first two experiments, participants were asked to read a story designed to induce sadness, and were then given a $1, $2, or $3 gift. In both, reported sadness was higher for persons receiving a $2 gift than for those receiving either a $1 or $3 gift. However, the increase in sadness from the $1 to $2 group failed to reach an acceptable level of significance. In the second experiment, as expected, a $1 gift produced less sadness than did the story by itself, and as in the first experiment, a $2 gift resulted in more sadness than either a $1 or $3 gift. The third experiment replicated the $1 and $2 conditions and obtained a highly reliable effect; sadness was greater among those who received the $2 gift. Measures of positive affect suggested that participants experienced either sadness or positive feelings, not both.  相似文献

The use of closed scales (with anchors at each end) to measure pain was found to produce ceiling effects characterized by a deceleration of ratings toward the upper end of the scale. This was consistent with previous research. Apart from producing nonlinear functions, the closed scale also limited test-retest reliability because of subjects’ tendencies to correct their distorted ratings in subsequent trials. However, an open-ended scale coupled with transformation of reported ratings into a decile scale virtually eliminated the ceiling effect, thus producing consistently linear functions and maximizing test-retest reliability. This finding may have implications for the measurement of other sensory and psychological phenomena, especially those in which the property evaluated varies in a continuous fashion.  相似文献

The moments of a nonnegative bounded waveform (e.g., bounded probability density functions or responses that can be expressed as bounded probability density functions) provide the basis for characterizing the waveform. Traditionally, only the lower-order moments (k ≤ 4) have been utilized in deriving topographical indices of these waveforms. Recent advances in waveform moment analysis, however, have made it possible to derive comprehensive and interpretable indices of complex nonnegative bounded waveforms by utilizing both lower-order and higher-order moments. Waveform moment analysis is reviewed briefly, and a flexible and efficient computer program is presented for conducting waveform moment analyses.  相似文献

In this study, we investigated biomechanical contributions of the high guard position of the arms observed only in a subgroup of toddlers at very early stages of gait development. Six healthy toddlers who showed this peculiar arm posture were involved in this study. They participated in two data collection sessions (1 month apart). We used three-dimensional analysis of arm posture during gait to estimate the changes in forces and torques generated by the arms and acting on the upper trunk segment. Across visits, toddlers’ increase in walking speeds coincided with lowering arm postures. Despite the apparent trend of changes in arm posture in this group of toddlers, the interaction between arm posture and upper trunk position created a variety of changes in forces and torques among individuals. Findings of this study exhibited an example of the exploration of dynamics by toddlers in the early stage of gait development.  相似文献

The authors' goals in this article are to (a) describe a new task for the assessment of shifting attention between different affective stimuli, The Children's Attentional Shifting Task (CAST); (b) present the theoretical background for the development of the CAST; and (c) report initial information on the developmental appropriateness and validity of the CAST. The task was tested using a sample of kindergarten and 1st-grade children, 50% of whom had social and conduct problems. Preliminary analyses showed that the CAST was not subject to problems arising from fatigue or loss of interest. Moreover, children's ability to shift attention away from angry facial expressions was positively related to teachers' ratings of their ability to shift attention and parents' reports of children's emotion regulation. Shifting away from negative affect also predicted children's academic performance as reported by teachers.  相似文献
