In-Home Parent-Child Interaction Therapy: Clinical Considerations

ABSTRACT

Parent-Child Interaction Therapy (PCIT) is an empirically-supported behavioral parent training program designed to be administered in a clinic or laboratory-based setting. Recently, an empirical investigation revealed that in-home PCIT produced comparable results as the PCIT trials conducted in more controlled environments (this issue). Administering PCIT in a home setting carries both drawbacks and advantages. This article provides an overview of both the positive and negative clinical aspects of conducting in-home PCIT and presents effective solutions to potential treatment barriers.     

Aversive Racism and Resistance to Affirmative Action: Perception of Justice Are Not Necessarily Color Blind

This study utilized a factorial survey design to assess attitudes toward affirmative action as a function of targeted group (Black, handicapped, or elderly persons), framing of the policy (with or without social justification), and institutional context (business, college, or social organization). Resistance to affirmative action was aroused more by policies specifying Blacks as the targeted group and by policies presented without justification. Supportive of the aversive racism framework, the level of resistance to the policies presented without justification for Blacks as the target group was higher than for all other targeted groups with or without justification. Implications for these findings for strategies to reduce negative attitudes toward affirmative action are discussed.     

Parent-Child Interaction Therapy for ADHD: A Conceptual Overview and Critical Literature Review

ABSTRACT

Attention-Deficit/Hyperactivity Disorder (ADHD), a chronic disorder beginning in childhood, is identifiable and diagnostically valid during the preschool years. Compared to school-aged children, preschoolers have not received as much attention in the literature. Parent-Child Interaction Therapy (PCIT) is an empirically-supported parent training program for young children with disruptive behaviors that may also be effective in treating ADHD. The purpose of the current article was to explore the theoretical rationale for utilizing PCIT with this population and to conduct a literature review of published PCIT treatment outcome studies that measured ADHD symptoms. The literature demonstrates that children with ADHD have been included in PCIT research and evidence suggests that PCIT may be effective for young children with ADHD. However, future research is needed to specifically examine the effects of PCIT on ADHD.     

Rapid serial visual presentation display on a small screen: reading Chinese while walking

This study examined the effects of presentation unit (word-by-word or single line) and presentation duration [171, 213, 240, and 308 msec. per character (msec./C)] on the comprehension of Chinese rapid serial visual presentation (RSVP) displays read from the small screen of a mobile phone in three different contexts (seated, walking on a treadmill, and walking through an outdoor course). 30 native Chinese readers ages 19 to 26 were recruited as participants. Scores on reading comprehension showed that presentation unit and presentation duration significantly affected reading comprehension, and interactions between factors were also significant. When the presentation unit was word-by-word, no significant difference in reading comprehension was observed under different presentation durations. However, when the presentation unit was a single line, reading comprehension deteriorated with the shortest presentation duration of 171 msec./C. With regard to context, participants had a higher mean reading comprehension score in the seated context than in walking contexts, but the difference was not significant.     

The Application of the Preschool Child Behavior Checklist and the Caregiver–Teacher Report Form to Mainland Chinese Children: Syndrome Structure,Gender Differences,Country Effects,and Inter-Informant Agreement

Preschool children have long been a neglected population in the study of psychopathology. The Achenbach System of Empirically Based Assessment (ASEBA), which includes the Child Behavior Checklist/1.5-5 (CBCL/1.5-5) and the Caregiver-Teacher Report Form (C-TRF), constitutes the few available measures to assess preschoolers with an empirically derived taxonomy of preschool psychopathology. However, the utility of the measures and their taxonomy of preschool psychopathology to the Chinese is largely unknown and has not been studied. The present study aimed at testing the cross-cultural factorial validity of the CBCL/1.5-5 and C-TRF, as well as the applicability of the taxonomy of preschool psychopathology they embody, to Mainland Chinese preschoolers. Country effects between our Chinese sample and the original U.S. sample, gender differences, and cross-informant agreement between teachers and parents were also to be examined. A Chinese version of the CBCL/1.5-5 and C-TRF was completed by parents and teachers respectively on 876 preschoolers in Mainland China. Confirmatory factor analysis (CFA) confirmed the original, U.S.-derived second order, multi-factor model best fit the Chinese preschool data of the CBCL/1.5-5 and C-TRF. Rates of total behavior problems in Chinese preschoolers were largely similar to those in American preschoolers. Specifically, Chinese preschoolers scored higher on internalizing problems while American preschoolers scored higher on externalizing problems. Chinese preschool boys had significantly higher rates of externalizing problems than Chinese preschool girls. Cross-informant agreement between Chinese teachers and parents was relatively low compared to agreement in the original U.S. sample. Results support the generalizability of the taxonomic structure of preschool psychopathology derived in the U.S. to the Chinese, as well as the applicability of the Chinese version of the CBCL/1.5-5 and C-TRF.     

Expression of VGLUTs contributes to degeneration and acquisition of learning and memory

Vesicular glutamate transporters (VGLUTs), which include VGLUT1, VGLUT2 and VGLUT3, are responsible for the uploading of L-glutamate into synaptic vesicles. The expression pattern of VGLUTs determines the level of synaptic vesicle filling (i.e., glutamate quantal size) and directly influences glutamate receptors and glutamatergic synaptic transmission; thus, VGLUTs may play a key role in learning and memory in the central nervous system. To determine whether VGLUTs contribute to the degeneration or acquisition of learning and memory, we used an animal model for the age-related impairment of learning and memory, senescence-accelerated mouse/prone 8 (SAMP8). KM mice were divided into groups based on their learning and memory performance in a shuttle-box test. The expression of VGLUTs and synaptophysin (Syp) mRNA and protein in the cerebral cortex and hippocampus were investigated with real-time fluorescence quantitative PCR and western blot, respectively. Our results demonstrate that, in the cerebral cortex, protein expression of VGLUT1, VGLUT2, VGLUT3 and Syp was decreased in SAMP8 with age and increased in KM mice, which displayed an enhanced capacity for learning and memory. The protein expression of VGLUT2 and Syp was decreased in the hippocampus of SAMP8 with aging. The expression level of VGLUT1 and VGLUT2 proteins were highest in KM mouse group with a 76-100% avoidance score in the shuttle-box test. These data demonstrate that protein expression of VGLUT1, VGLUT2 and Syp decreases age-dependently in SAMP8 and increases in a learning- and memory-dependent manner in KM mice. Correlation analysis indicated the protein expression of VGLUT1, VGLUT2 and Syp has a positive correlation with the capacity of learning and memory.     

Motivational incentives modulate age differences in visual perception

This study examined whether motivational incentives modulate age-related perceptual deficits. Younger and older adults performed a perceptual discrimination task in which bicolored stimuli had to be classified according to their dominating color. The valent color was associated with either a positive or negative payoff, whereas the neutral color was not associated with a payoff. Effects of incentives on perceptual efficiency and response bias were estimated using the diffusion model (Ratcliff, 1978). Perception of neutral stimuli showed age-related decline, whereas perception of valent stimuli, both positive and negative, showed no age difference. This finding is interpreted in terms of preserved top-down control over the allocation of perceptual processing resources in healthy aging.     

政治哲学视域中的明代王学兴起

明代王学作为一个主旨大体相近的思想共同体,在中晚明社会大兴其道。王学的兴起,蕴含着值得我们反思的政治意味。王学切中当时思想界溺于旁求外袭的时弊,注重个体的内在资源对于社会生活、政治生活的意义,将治世之事转向内在的治心之事;王学在理论上简易直接、打动人心,王学中人多希望以悦服心灵的方式来推行儒家的理想、教条和秩序,其意在"收拾人心"并进而实现政治理想;王学中人深入民间进行社会教育,在明代严酷的官场政治之外,通过简易平常的哲学话语以及书院会讲、制定乡约等手段来改造心灵和社会,表明了王学在政治鼓动问题上提倡向下的社会路线。     

1993至2009年大学生焦虑的变迁:一项横断历史研究

有研究表明,中学生的焦虑水平在逐年上升,那么大学生的焦虑水平是如何随年代变化的呢?大学生的焦虑水平是否存在性别差异呢?为此,我们选取1993至2009年间以Spielberger编制的状态-特质焦虑量表测量大学生状态焦虑的63篇和特质焦虑的66篇研究报告进行横断历史的元分析,以考察大学生状态和特质焦虑水平历年的变化情况和性别差异。结果表明:(1)1993至2009年大学生状态和特质焦虑均值与年代有显著正相关,这说明大学生的焦虑水平在逐年上升;(2)大学生状态焦虑增长速度要快于特质焦虑,而且年代对状态焦虑变异的解释率也高于特质焦虑;(3)在状态和特质焦虑上男女大学生得分都与年代有显著正相关,且在两种焦虑得分上均无显著的性别差异。
