AbstractBackground: Research about gender identity development is still in its infancy, especially among youth who experience gender dysphoria and are accessing gender-affirming medical care.Aims: This article contributes to the literature on how gender identity and gender dysphoria is experienced, expressed and addressed by youth who have started, or are just about to start, a gender-affirming medical intervention.Methods: The project draws from qualitative interviews with 36 trans children and youth of different ages and stages of puberty. The data were collected in three specialized Canadian clinics that offer gender-affirming care and they were analyzed through inductive thematic analysis.Results: Two interlinked dimensions of the youth’s lives allow meaning-making of their gender identity: 1) internal or personal and 2) interactional or social processes. Careful analysis reveals three gender identity development pathways that may be taken by youth, from early questioning to the affirmation of their gender identity. A discussion of current models of gender identity development and their limitations concludes the article. 相似文献

This study examines the effects of a verbal collateral (counting) on a series of three differential reinforcement of low rates of response (DRL) tasks with progressively longer interresponse time requirements (DRL-2, DRL-6 and DRL-12). Forty-eight 10-year-old children, divided according to sex and conceptual tempo (fast-inaccurate vs. slow-accurate) participated in DRL training, half of them being instructed to count aloud between responses. Counting was found to be related to faster learning of all the tasks and to greater efficiency in obtaining reinforcement in most cases. It also eliminated differences due to sex and conceptual tempo except in DRL-12. However, it had the disadvantage of causing inexact temporal discrimination. The results were replicated in a group of 8-year-old subjects performing the same tasks. 相似文献

ABSTRACT Risky sexual behavior among teenagers in the United States is a noted public health concern. The purpose of this study is to examine the correlates and theoretical predictors of risky sexual behavior among American teens. Data from the Youth Risk Behavioral Survey was utilized with concepts from Routine Activities Theory guiding analyzes. Bivariate regression results indicated that components of Routine Activities Theory are moderate to strong predictors of using substances before sexual activity and having multiple sexual partners. 相似文献

Rule-governed behavior and derived stimulus relations have always shared strong conceptual links within behavior analysis. However, experimental analysis linking the two domains remains limited. The current study consisted of three experiments that aimed to continue to bridge this experimental gap. The first experiment sought to establish the extent to which a training version of the implicit relational assessment procedure (IRAP) could be used to establish and successfully reverse experimentally established derived relations. The results suggested that the Training IRAP could successfully produce derived reversals. Experiments 2 and 3 explored the extent to which reversed derived relations would control rule-governed behavior when the contingencies for rule-following competed with the rule. In Experiment 2, the task contingencies were immediately in opposition to the (reversed) derived rule, and participants generally responded in accordance with the task contingencies, rather than the rule. In Experiment 3, the task contingencies were initially rule-consistent before a contingency reversal that later made them rule-inconsistent. Here evidence of rule-persistence emerged. The results of the research are considered within the context of a recent framework that has emerged out of RFT for analyzing the dynamics involved in derived relational responding. 相似文献
