Subliminal Self-Help Tapes and Academic Achievement: An Evaluation

Marketing claims of effectiveness in improving academic achievement through the use of commercially prepared subliminal audiotapes were investigated. Students enrolled in a career development class were randomly assigned to an active treatment group (n=25), an inactive treatment group (n=26), or a control group (n=22). Participants in the treatment group listened to tapes with subliminal affirmations masked by ocean waves. The inactive treatment group listened to placebo tapes with ocean waves but no subliminal messages. Dependent variables used were final examination scores from the class and current semester grade point average. No treatment differences on either dependent measure were found. The implications of these findings are discussed.     

professional-paraprofessional Cooperation in career development

Nationwide the “in” term is career development. The task is to develop a delivery system that gets to people where they are. Peterson and his associates describe in detail how a career development “curriculum” is systematically developed by professional counselors for implementation by paraprofessionals and lay church workers. A key feature of this article is the needs assessment procedure, since the curriculum is being constructed on the results of this procedure. Rarely has such an assessment been undertaken, even more rarely with such comprehensiveness. This article describes what may well be the largest professional-paraprofessional cooperative effort in the world.

Correlation between Changes in Stress-Induced Corticosterone Secretion and GR mRNA Levels

The current study was conducted to determine the potential relationship between stress-induced corticosterone secretion and corticosteroid receptor mRNA levels after 5 days of intermittent stress. In particular, we were interested in the rate at which animals terminate a stress response, and how this termination may be altered by repeated stress. Adult male Sprague-Dawley rats were subjected to either 5 days of restraint stress or 5 days of an unpredictable stress paradigm. Restraint-stress induced corticosterone secretion was measured on Days 1 and 5 in both groups, and animals were killed on Day 6. Glucocorticoid receptor (GR), and mineralocorticoid (MR) mRNA levels were determined using in-situ hybridization techniques. Five days of restraint stress caused an habituation of the plasma corticosterone response to stress measured 60 and 90 min post-stress initiation; this pattern of corticosterone secretion was not observed in the animals subjected to unpredictable stress. Five days of either stress paradigm did not alter MR mRNA levels measured within the hippocampus or GR mRNA levels within the hippocampus or the medial parvocellular division of the paraventricular nucleus of the hypothalamus (mpPVN). However, an individual's GR mRNA levels measured within the CA1/2 region of the hippocampus and the mpPVN were significantly correlated with the degree of habituation of the corticosterone response to stress measured on Day 5. This suggests that an increase in the rate of termination of the stress response and levels of GR within the hippocampus and mpPVN may be functionally related.     

高风险婴儿前瞻性纵向研究与孤独症谱系障碍早期识别

孤独症谱系障碍(Autism Spectrum Disorder, ASD)早期识别有助于早期诊断和早期干预的实施, 对于改善ASD儿童发育结果至关重要。高风险前瞻性纵向研究以高风险婴儿(ASD儿童的年幼同胞, 入组年龄小于12个月)作为主要研究对象, 通过对ASD高风险婴儿(24至36个月之间诊断为ASD的高风险婴儿)的早期发育轨迹的描绘和核心症状早期表现的识别, 为ASD早期识别提供了重要依据。未来可以增加被试数量、延长观察时间并密集观察时间点、关注伴发障碍、综合考虑遗传、环境和文化因素影响, 并结合早期干预研究进行深入探索。未来在中国开展相关研究具有重要的科学价值和临床意义。     

The Impact of Balanced Risk–Benefit Information and Initial Attitudes on Post‐Information Attitudes1

In a realistic social context, people are confronted with both positive and negative information, yet research on this topic is relatively scarce. We present 2 studies examining the role of initial attitudes on the impact of one‐sided vs. balanced positive and negative information on attitudes toward food production methods. The first experiment demonstrated that one‐sided information influenced post‐information attitudes congruent to the direction of the message content. The second experiment showed that the effect of balanced information on post‐information attitudes may depend on initial attitudes. These results demonstrate that negativity effects are dominant for people with initial positive attitudes, but change into positivity effects for people with initial negative attitudes. Implications for communicating both positive and negative information are discussed.     

威胁敏感性的概念和测量：生理和认知两种取向

对威胁敏感是人类在应对外部环境过程中不断发展的生存技能。威胁敏感性的研究主要存在两种取向：生理取向以敏感性强化理论为基础, 将行为抑制系统的敏感性界定为威胁敏感性, 量化为个体应对威胁时的生理、情绪和行为反应水平; 认知取向以信息加工的认知风格理论为基础, 将个体在对威胁信息加工过程中的敏感性偏向定义为威胁警觉, 量化为威胁刺激呈现前后的预期水平和探测水平。未来研究还需进一步整合和界定威胁敏感性的概念内涵, 验证各测量指标之间的关系, 拓展不同种类威胁敏感性的研究方法。
