中小学生对父母管教信息的认知、情绪与行为反应倾向

运用情境模拟的方法,对中小学生对父母管教信息的认知、情绪与行为反应倾向进行了研究。被试是616名中小学生。结果表明：(1)小学中年级以上学生对家长管教信息的情绪有较准确的认知;(2)不同管教信息的教育效能有优劣之分：诱导教诲最能引起被试的正面反应,其次是困扰担忧,伤心失望能引起部分学生的顺从反应,愤怒批评易引起子女的消极情绪和对抗行为。(3)父亲发出的管教信息比母亲更具权威性,更易引起子女积极的情绪体验与行为倾向。(4)学生对家长管教信息的反应具有明显的年龄和性别差异,小学生比中学生更易接受、顺从家长管教,女生比男生易产生更多的积极情绪与服从行为。(5)被试的认知评价与其情绪反应、行为倾向有较高的一致性。学生对父母管教信息的情绪体验和行为反应很大程度上取决于对管教信息的认知。如果学生的认知较为积极,更易引起积极的情绪体验和行为倾向。     

DSM-IV criteria for generalized anxiety disorder in older adults: distinguishing the worried from the well

This study compared 36 older adults with generalized anxiety disorder (GAD), 22 older adults with subsyndromal anxiety symptoms, and 32 normal controls on criteria of the Diagnostic and Statistical Manual of Mental Disorders (4th ed.) for GAD. GAD patients reported more frequent and uncontrollable worry, somewhat different worry content, higher prevalence of most associated symptoms, and more distress or impairment than the subsyndromal group or normal controls. Individuals with subsyndromal anxiety reported more excessive, frequent, and uncontrollable worry than asymptomatic individuals, along with more sleep disturbance, fatigue, and distress or impairment. Results indicate that the key features of late-life GAD are distress and impairment, frequency and uncontrollability of worry, muscle tension, and sleep disturbance and that clinicians treating older adults with GAD should monitor and treat residual symptoms.     

Effects of experience on fetal voice recognition

Abstract - The ability of human fetuses to recognize their own mother's voice was examined. Sixty term fetuses were assigned to one of two conditions during which they were exposed to a tape recording of their mother or a female stranger reading a passage. Voice stimuli were delivered through a loudspeaker held approximately 10 cm above the maternal abdomen and played at an average of 95 dB SPL. Each condition consisted of three 2-min periods: no stimulus, voice (mother or stranger), and no stimulus. Fetal heart rate increased in response to the mother's voice and decreased in response to the stranger's; both responses were sustained for 4 min. The finding of differential behavior in response to a familiar versus a novel voice provides evidence that experience influences fetal voice processing. It supports an epigenetic model of speech perception, presuming an interaction between genetic expression of neural development and species-specific experience.     

Enhanced human memory consolidation with post-learning stress: interaction with the degree of arousal at encoding

Abundant evidence indicates that endogenous stress hormones such as epinephrine and corticosterone modulate memory consolidation in animals. We recently provided the first demonstration that an endogenous stress hormone (epinephrine) can enhance human memory consolidation. However, these findings also suggested that post-learning stress hormone activation does not uniformly enhance memory for all recently acquired information; rather, that it interacts with the degree of arousal at initial encoding of material in modulating memory for the material. Here we tested this hypothesis by administering cold pressor stress (CPS) or a control procedure to subjects after they viewed slides of varying emotional content, and assessing memory for the slides 1 wk later. CPS, which significantly elevated salivary cortisol levels, enhanced memory for emotionally arousing slides compared with the controls, but did not affect memory for relatively neutral slides. These findings further support the view that post-learning stress hormone-related activity interacts with arousal at initial encoding to modulate memory consolidation.     

Rowed to recovery: the use of phonological and orthographic information in reading Chinese and English

To examine how readers of Chinese and English take advantage of orthographic and phonological features in reading, the authors investigated the effects of spelling errors on reading text in Chinese and English using the error disruption paradigm of M. Daneman and E. Reingold (1993). Skilled readers in China and the United States read passages in their native language that contained occasional spelling errors. Results showed that under some circumstances very early phonological activation can be identified in English, but no evidence for early phonology was found in Chinese. In both languages, homophone errors showed a benefit in measures of later processing, suggesting that phonology helps readers recover from the disruptive effects of errors. These results suggest that skilled readers take advantage of the special features of particular orthographies but that these orthographic effects may be most pronounced in the early stages of lexical access.

Thermal sensitivity in Tourette syndrome: preliminary report

The effects of heat on tic symptoms were studied in a sample of 78 adults with Tourette syndrome. 62 men and 16 women completed a survey concerning the type, onset, and course of their tics. 10 adult male subjects also participated in a thermal challenge during which ambient temperature was raised from 22 degrees C to 35 degrees C following a control period. Of the 78, 24% or 19 reported increased tics upon exposure to heat. Compared to the remaining 59 subjects, there were no differences in sex distribution, current age, or overall course of illness. In the thermal challenge, there was general increase in tics that was correlated with sweat rate (r = .55, p = .001). This effect was prominent in 5 of 10 subjects (rs = .29 to .63). There were no mean differences in current age, age of onset, or current severity of symptoms between the five subjects of each group. Tic symptoms in a subgroup of patients with Tourette syndrome may be sensitive to heat. Abnormal heat regulation is not a likely explanation for the observed increase in tics. The increase may be due to normal heat-loss mechanisms through dopaminergic pathways.     

声旁与整字的音段、声调关系对形声字命名的影响

采用命名任务研究了汉字形声字的声旁与整字的音段、声调关系对形声字命名反应时的影响,探讨声旁的音段、声调在汉字形声字发音中的作用。实验材料是180个汉字形声字。实验结果表明,汉字形声字的声旁与整字的音段关系对命名时间有重要影响。汉字形声字的命名存在着“规则效应”,声旁与整字音段相同时反应快,声旁与整字音段相异时反应慢。汉字形声字的命名也存在着“声调效应”。声旁与整字的声调关系对命名有重要影响。当声旁与整字声调相同时反应快,当声旁与整字声调相异时反应慢,这种效应不受字频影响。整个实验结果支持汉字认知中强的亚词汇成分自动激活的观点。     

A parallel distributed processing model of stimulus-stimulus and stimulus-response compatibility.

A parallel distributed processing (PDP) model is proposed to account for choice reaction time (RT) performance in diverse cognitive and perceptual tasks such as the Stroop task, the Simon task, the Eriksen flanker task, and the stimulus-response compatibility task that are interrelated in terms of stimulus-stimulus and stimulus-response overlap (Kornblum, 1992). In multilayered (input-intermediate-output) networks, neuron-like nodes that represent stimulus and response features are grouped into mutually inhibitory modules that represent stimulus and response dimensions. The stimulus-stimulus overlap is implemented by a convergence of two input modules onto a common intermediate module, and the stimulus-response overlap by direct pathways representing automatic priming of outputs. Mean RTs are simulated in various simple tasks and, furthermore, predictions are generated for complex tasks based on performance in simpler tasks. The match between simulated and experimental results lends strong support for our PDP model of compatibility.     

Adolescent Substance Use: Preliminary Examinations of School and Neighborhood Context

In considering the influences of microsystems on adolescent substance use, familial and peer contexts have received the most extensive attention in the research literature. School and neighborhood settings, however, are other developmental contexts that may exert specific influences on adolescent substance use. In many instances, school settings are organized to provide educational services to students who share similar educational abilities and behavioral repertoires. The resulting segregation of students into these settings may result in different school norms for substance use. Similarly, neighborhood resources, including models for substance use and drug sales involvement, may play an important role in adolescent substance use. We briefly review literature examining contextual influences on adolescent substance use, and present results from two preliminary studies examining the contribution of school and neighborhood context to adolescent substance use. In the first investigation, we examine the impact of familial, peer, and school contexts on adolescent substance use. Respondents were 283 students (ages 13 to 18) from regular and special education classrooms in six schools. Although peer and parental contexts were important predictors of substance use, school norms for drug use accounted for variance in adolescent use beyond that explained by peer and parental norms. Data from a second study of 114 adolescents (mean age = 15) examines neighborhood contributions to adolescent substance use. In this sample, neighborhood indices did not contribute to our understanding of adolescent substance use. Implications for prevention are presented.
