The parenting attitudes of adolescent and older mothers were assessed at 1 and 12 months postpartum to explore group differences and determine if these attitudes predicted quality of home environment and parenting behaviors at 12 months. Adolescent mothers scored significantly lower than did older mothers in empathy toward children's needs, but there were no significant group differences on three other parenting attitude constructs. There were no significant correlations between parenting attitudes at 1 month and parenting behaviors at 12 months for either group. For adolescent mothers at 12 months postpartum, the only attitude construct that was significantly related to concurrent quality of parenting was developmental expectations of the child. These and other findings are discussed in the context of current theory and intervention related to adolescent parenting.  相似文献

The size of the perceptual unit used in reading was addressed using the predesignated target paradigm. Sixteen subjects viewed the following stimuli in random order: the words tee, the, tie, and toe; the nonwords eet, eht, eit, and eot; and the letters e, h, i, and o. Subjects fixated on the location of the center letter and identified the letter as e, h, i, or o, alternatives which were known to them at the onset. A word superiority effect was obtained for the common word the but not for the less common words tee, tie, and toe. The word superiority effect was attributable to bias rather than discriminability: Subjects exhibited a bias to perceive the words in this experiment as the (i.e., there was a bias to perceive h in the t e stimulus presentations). These results suggest that the common word the is processed in reading units that are larger than the letter, and that the system is biased to perceive common rather than uncommon words in data-limited conditions.  相似文献

In dealing with college age (18-22) males, clinical observations have shown a fairly common inability to successfully form intimate relationships with same-age females. This problem often appears to be due to an inability to bond and trust that is rooted in the formative years in the nuclear home. When this happens, the young male frequently develops a fear of being sexually abnormal, perhaps even homosexual. This manifests itself in shame, anxiety, depression, denial, reaction formation, performance anxiety, concern about being found out, isolation, substance abuse and, occasionally, acting out. Getting such persons to admit these fears is generally extremely difficult, requiring gentle and empathetic, but persistent, probing on the part of the therapist. Therapy consists of understanding and acceptance by the client that these fears are most often reactive, that they are commonly held, and that when they are seen in proper perspective, they often diminish. The present paper reviews some of the literature on sexual developmental issues of the adolescent male as a backdrop for this problem. The specific difficulties related to reactive homophobia are explored, and some therapeutic approaches suggested.  相似文献

The effectiveness of an integrated treatment program utilizing cognitive-behavioral therapies for Panic Disorder was examined. Treatment was comprised of Cognitive Model of Panic-derived procedures, Cognitive Therapy and Applied Relaxation Training. Subjects meeting DSM-III-R criteria for Panic Disorder received thirteen 2.5-hr sessions of outpatient therapy in small groups, over a 12-week period. Subjects were given an extensive rationale of the etiology, development and maintenance of Panic Disorder, within the framework of the Cognitive Model of Panic, and controlled behavioral experiments in panic evocation to internal panicogenic cues, cognitive reappraisal of somatic and ideational cues, breathing retraining, Applied Relaxation Training and Cognitive Therapy to identify and remediate maladaptive beliefs and dysfunctional cognitive schemas. A comprehensive assessment battery was given at pre-mid-post-treatment which included measures of tripartite functioning, global severity, panic, fear, anxiety, depression and psychiatric symptomatology. Analyses indicated statistically significant improvements across all outcome domains. All subjects were free of spontaneous (uncued) panic attacks at post-treatment, and all met operationalized criteria for high endstate functioning. These findings are discussed, with recommendations for future research.  相似文献

As part of a long-term followup study of the outcome of psychoanalysis, we examined the relation between the extent of resolution of the transference at termination and the characteristics of the patient-analyst match. For twelve of the seventeen patients interviewed five to ten years after termination of psychoanalysis, the researchers found that the patient-analyst match played a role in the outcome of the analysis. Illustrations of the influence of the match in cases where the transference was resolved and those where it was not are presented.  相似文献

Seven out of 17 patients interviewed in a long-term followup of psychoanalysis showed either improvement in psychological functioning or a retention of psychological gains they had made during the course of psychoanalysis. Six patients deteriorated in their psychological functioning, but their gains were restored with subsequent treatment. Four patients deteriorated in psychological functioning without restoration, whether or not treatment was reentered. Neither analysts' assessments at the time of termination nor patients' assessments of themselves or assessments based on psychological tests one year after termination predicted which patients would improve or retain psychological change. No causal generalizations about factors related to psychological change can be made from these data. Different factors in interaction are suggested to account for the stability and instability of psychological change.  相似文献

Agoraphobia is reputed to be more difficult to treat than simple phobia. In a test of this supposition, 38 agoraphobics and 19 simple phobics were each given 10 sessions of graduated in vivo exposure. They were assessed before and after therapy using a behavioral avoidance test, behavioral diaries, and self-report measures. Analysis of covariance revealed unequivocal posttest differences only on self-assessed disability level; agoraphobics had changed less in their report of global disability immediately following treatment but not at follow-up. Sixty-eight percent of the simple phobics showed clinically significant improvement on avoidance of the Main Phobia, compared with 34% of the agoraphobics. On three other outcome measures, including more precise behavioral measures of phobia, agoraphobics and simple phobics responded equivalently to treatment. Given clinicians' impression about the comparative difficulty in treating agoraphobic clients, fewer differences in treatment response were obtained than were expected. Several possible explanations for this discrepancy are discussed.  相似文献

Noting that a wide variety of unpleasant feelings, including sadness and depression, apparently can give rise to anger and aggression, I propose a cognitive-neoassociationistic model to account for the effects of negative affect on the development of angry feelings and the display of emotional aggression. Negative affect tends to activate ideas, memories, and expressive-motor reactions associated with anger and aggression as well as rudimentary angry feelings. Subsequent thought involving attributions, appraisals, and schematic conceptions can then intensify, suppress, enrich, or differentiate the initial reactions. Bodily reactions as well as emotion-relevant thoughts can activate the other components of the particular emotion network to which they are linked. Research findings consistent with the model are summarized. Experimental findings are also reported indicating that attention to one's negative feelings can lead to a regulation of the overt effects of the negative affect, I argue that the model can integrate the core aspect of the James-Lange theory with the newer cognitive theories of emotion.  相似文献
