Parents can play a vital role in shaping teenagers’ sexual attitudes, behavior, and contraceptive use through communication, however, less is known about how to modify parent–adolescent communication among youth with mental health problems. The impact of a family-based sexual risk prevention intervention on both observational and self-report of parent–adolescent sexual communication was examined at 12 months among adolescents with mental health problems. Of the 721 parent–adolescent dyads recruited for the study, 167 videotapes of sexual discussions between parents and adolescent were coded for the family-based intervention and 191 videotapes for the active comparison. Longitudinal analyses examined differences between conditions (family-based vs. comparison) in self-reported and observed parent–adolescent sexual discussions and also examined the impact of gender on intervention response. More parent I-statements, healthier parent body language, and fewer adolescent Negative Vocalizations were detected for family-based intervention participants 12 months after participating in the brief intervention (11?h of total intervention time) relative to those in the comparison condition. Parents in the family-based intervention also self-reported better sexual communication at 12 months. The current study provides supporting evidence that a relatively brief family-based intervention was successful at addressing parent–adolescent sexual communication among a mental health sample. 相似文献

The contribution of executive control to semantic cognition: Convergent evidence from semantic aphasia and executive dysfunction 下载免费PDF全文

Semantic cognition, as described by the controlled semantic cognition (CSC) framework (Rogers et al., 2015 , Neuropsychologia, 76, 220), involves two key components: activation of coherent, generalizable concepts within a heteromodal ‘hub’ in combination with modality‐specific features (spokes), and a constraining mechanism that manipulates and gates this knowledge to generate time‐ and task‐appropriate behaviour. Executive–semantic goal representations, largely supported by executive regions such as frontal and parietal cortex, are thought to allow the generation of non‐dominant aspects of knowledge when these are appropriate for the task or context. Semantic aphasia (SA) patients have executive–semantic deficits, and these are correlated with general executive impairment. If the CSC proposal is correct, patients with executive impairment should not only exhibit impaired semantic cognition, but should also show characteristics that align with those observed in SA. This possibility remains largely untested, as patients selected on the basis that they show executive impairment (i.e., with ‘dysexecutive syndrome’) have not been extensively tested on tasks tapping semantic control and have not been previously compared with SA cases. We explored conceptual processing in 12 patients showing symptoms consistent with dysexecutive syndrome (DYS) and 24 SA patients, using a range of multimodal semantic assessments which manipulated control demands. Patients with executive impairments, despite not being selected to show semantic impairments, nevertheless showed parallel patterns to SA cases. They showed strong effects of distractor strength, cues and miscues, and probe–target distance, plus minimal effects of word frequency on comprehension (unlike semantic dementia patients with degradation of conceptual knowledge). This supports a component process account of semantic cognition in which retrieval is shaped by control processes, and confirms that deficits in SA patients reflect difficulty controlling semantic retrieval. 相似文献

This study determined if previously reinforced academic responding recurred when alternative responses were differentially reinforced and subsequently placed on extinction, and whether the magnitude of resurgence was related to the rate of differential reinforcement for the alternative behavior. Three kindergarten students read Greek letters aloud as arbitrary consonant–vowel blends. Resurgence was reliably demonstrated within and across participants, and the magnitude of resurgence was related to the prior rate of differential reinforcement of alternative behavior. 相似文献

In Appalachia, there are certain Christian sects who handle venomous serpents in their church services. Although their serpent handling has received some attention, another of their practices, poison-drinking, has all but escaped the concern of investigators. Addressing this issue, this study included phenomenological interviews with seven believers who ingested strychnine at church. A hermeneutic analysis of their transcribed interviews discovered four major themes that emerged across all protocols to describe the structure of meaning in the experience of poison-drinking: (1) Desire to Drink; (2) “God Moving on Me” (in terms of Anointing and “Insurance” against Harm); (3) Already “Snake Bit”; and (4) “Victory”/“Devil Troubling My Mind”. These interdependent themes are discussed in relation to the existential grounds of body, others, time, and world. 相似文献
