Key pecking of pigeons was reinforced on a variable-interval schedule when ambient illumination came from a green light, but not when it came from a red, yellow, or white light. The different hues were randomly presented for periods of 30 sec each, with the restriction that white never followed red. After discriminative control was established, the pigeons were tested with the same procedure used during training, except that white sometimes followed red. Significantly more responses were made during white-following-red than during white following either green or yellow. These findings indicate that, in changing from red to white, complementary afterimages can be induced in pigeons for a brief period of time. By providing behavioral evidence for afterimages in the pigeon, this technique may be useful to research in comparative neurophysiology, animal discrimination learning, and theories of color vision. 相似文献

Growing evidence supporting the effectiveness of Collaborative/Therapeutic Assessment (C/TA) has led clinicians and researchers to apply C/TA to a variety of clinical populations and treatment settings. This case example presents a C/TA inpatient adaptation illustrated with narcissistic personality disorder. After a brief overview of salient concepts, I provide a detailed account of the clinical interview, test interpretation paired with diagnostic considerations specific to narcissism, planned intervention, and discussion of assessment results. Throughout the case study, I attempt to demonstrate defining features of C/TA, inpatient adaptations, and clinical techniques that encourage meaningful engagement with a “hard to reach” personality. 相似文献

Behavioral parent training (BPT) interventions for child behavior problems have been based on decades of research that demonstrate links between particular parent behaviors and child externalizing problems. However, the majority of this research has been conducted with European-American (EA) families, and less is known about whether these findings can be generalized to Mexican Americans (MAs). In the current study, we investigated self-reported parenting practices that have been associated with externalizing behavior problems among EA families (harsh parenting, inconsistency, and low parental warmth), to determine if those practices can also differentiate MA mothers whose young children have clinically significant behavior problems from MA mothers whose children do not have behavior problems. Participants were 115 MA families with young children, 58 with a child with clinically significant behavior problems and 57 with a child in the normal range for such problems. Results indicated that MA mothers whose children have behavior problems self-reported significantly less warmth and consistency and more harsh parenting compared to parents whose children’s behavior was in the normal range. These findings indicate that parenting behaviors that are associated with externalizing behavior problems among EA families are associated with the same problems among MA families with young children, suggesting that parent training interventions designed to target these behaviors are also likely to be relevant to MA families with children in this age range. However, findings also indicate that parenting behaviors differ depending on acculturation level, suggesting that BPT programs must respond to variation in normative parenting practices for MA families. 相似文献
