Synchrony has been broadly conceptualized as the quality of the parent-child dyadic relationship. Parenting, factors that compromise caregiving quality, and child characteristics have all been theoretically linked to synchrony, but little research has been conducted to validate such associations. The present study examined correlates of synchrony including parenting, maternal psychological resources and child attributes, among a sample of 120 mother-son dyads who were participating in a treatment study for children identified as being at risk for developing early conduct problems. There families participated in an at-home assessment, which included a series of mother-son interactions. Synchrony was associated with aspects of parenting and child attributes, including maternal nurturance, and child emotional negativity and language skills. The findings are discussed in terms of parent and child contributions to the development of synchrony. 相似文献

The purpose of this study was to determine the percentage of borderline patients who first engaged in self-mutilation as children and to compare the parameters of their self-harm to those of borderline patients who first harmed themselves at an older age. Two hundred and ninety inpatients meeting both Revised Diagnostic Interview for Borderlines (DIB-R; Zanarini, Gunderson, Frankenburg, & Chauncey, 1989) and Diagnostic and Statistical Manual of Mental Disorders (3rd ed. ref.) (DSM-III-R; APA, 1987) criteria for borderline personality disorder were interviewed about their history of self-mutilation. Of the 91% with a history of self mutilation, 32.8% reported first harming themselves as children (12 years of age or younger), 30.2% as adolescents (13-17 years of age), and 37% as adults (18 or older). Using logistic regression analyses and controlling for baseline age, it was found that those with a childhood onset reported more episodes of self-harm, a longer duration of self-harm, and a greater number of methods of self-harm than either those with an adolescent or adult onset to their self-mutilation. The results of this study suggest that a sizable minority of borderline patients first engage in self-harm as children and that the course of their self-mutilation may be particularly malignant. 相似文献

What attributions must any actor make to an other in order to engage in face-to-face interaction with that other? Edmund Husserl's use of “analogues” suggests that actors use their own experiences of themselves as a starting pointin making such attributions. Alfred Schutz and Erving Goffman claim that for face-to-face interaction to occur, an other must be recognized as copresent and reciprocity must be established. I assert here that the means for determining that these conditions have been met will vary. I explore a varietyof actors and in particular their differing identifications of interactionally available others and I take as problematicthe establishment of co-presence and reciprocity. Taking others to be “analogues of ourselves” serves as a useful starting point, but worthy of detailed analysis is howand with whom an actor draws the analogy, under what circumstances it comes in for revision, and the interactional consequences of the decisions made. 相似文献

Bi-factor and multiple-factor analyses of the same data are compared in two respects. First, two criteria are suggested for determining when the factorization is adequate. This problem being more acute for the centroid method than for the bi-factor method, the latter is used primarily for comparison only. It is shown also that the omission from the simple structure of entries smaller than .10 yields a pattern which is a poorer fit to the original correlations than is the bi-factor pattern. Second, the second-order general factor obtained from the intercorrelations of the primaries is found to be highly correlated with the general factor of the bi-factor pattern. 相似文献

The study investigates the idea that within-session changes in responding are produced by arousal and satiation. General activity, measured by the displacement of floor panels, was used as an index of these variables. In Experiment 1, pigeons pecked a key on a simple variable-interval schedule and general activity was also recorded. In Experiment 2, pigeons received response-independent reinforcers. In Experiment 3, the pigeons' general activity was reinforced on a variable-interval schedule. Although significant within-session changes in operant key pecking were observed in Experiment 1, within-session changes in general activity were seldom observed in either Experiment 1 or Experiment 2. Significant within-session changes in general activity were observed in Experiment 3, when activity was the operant. The present results can potentially be explained by arousal and satiation. However, the predictive power of this explanation is severely limited. Regardless of whether one accepts arousal and satiation as the theoretical explanation for within-session changes in responding, the present results suggest that aspects of the response–reinforcer relation may determine the within-session pattern of responding. 相似文献

Rats pressed levers for food delivered by several fixed interval schedules. A drinking spout or running wheel was also available during some conditions, but not during others. The rate of lever pressing, drinking and running often changed within experimental sessions. The within-session patterns of lever pressing did not differ when drinking or running was available and when it was not. The correlation between the amount of lever pressing and the amount of drinking or running at a particular time in the session was inconsistently positive or negative. Finding within-session changes in responding for adjunctive behaviors implies that the factors that produce these changes are present for both adjunctive and instrumental behavior. Finding inconsistent correlations between instrumental responding and adjunctive behaviors questions arousal and interference from adjunctive behaviors as explanations for within-session changes in instrumental responding. 相似文献

GESTURE, SPEECH, AND LEXICAL ACCESS: 总被引:1,自引:0,他引:1
Abstract— In a within-subjects design that varied whether speakers were allowed to gesture and the difficulty of lexical access, speakers were videotaped as they described animated action cartoons to a listener. When speakers were permitted to gesture, they gestured more often during phrases with spatial content than during phrases with other content. Speech with spatial content was less fluent when speakers could not gesture than when they could gesture, speech with nonspatial content was not affected by gesture condition. Preventing gesturing increased the relative frequency of nonjuncture filled pauses in speech with spatial content, but not in speech with other content. Overall, the effects of preventing speakers from gesturing resembled those of increasing the difficulty of lexical access by other means, except that the effects of gesture restriction were specific to speech with spatial content. The findings support the hypothesis that gestural accompaniments to spontaneous speech can facilitate access to the mental lexicon 相似文献

Large and systematic changes in response rates often occur within sessions during operant conditioning procedures. In the present experiment, we asked whether the value of the reinforcer that supports responding also changes within sessions. Pigeons pecked a key for mixed grain available throughout the session. Occasionally, wheat was also provided for pecking a second key. The ratio of the rates of responding for mixed grain and wheat, a frequently used measure of relative reinforcer value, changed significantly within sessions when mixed grain was provided at high, but not at low, rates. Habituation to the reinforcer provides the most likely explanation for these changes in reinforcer value. Eventually, habituation may provide a unified explanation for the within-session changes in behavior that occur when many species of subjects respond on a wide variety of tasks. 相似文献

Ninety children and adolescents admitted to two state-operated psychiatric hospitals were followed from the time of their admission through one year post discharge. Data were collected from the children and adolescents, their families and clinicians at three intervals (during hospitalization, three months post discharge, and one year post discharge) to identify demographic, clinical, and service history characteristics of the children and adolescents, as well as to track their placement and other dispositional status following discharge from the hospital. The data indicated that the children and adolescents were seriously emotionally and behaviorally disturbed, came from families which were economically disadvantaged, and did not typically live in two-parent families. While the majority of the children and adolescents received recommended aftercare services during the three months following discharge from the hospital, there was a decline in placement stability for the children at the one-year post discharge followup. The most important predictors of successful outcome at discharge were living with a family member at the time of hospitalization and the participation of the family in the treatment planning during hospitalization. 相似文献
