论分子生物学时代的生理学探索 --微观与宏观的统一

20世纪中期,随着蛋白质空间结构的解析和DNA双螺旋结构的发现,形成了核酸和蛋白质为主要研究对象的分子生物学时代,然而随着科学研究的不断深入微观,越来越多的科学家意识到认为将复杂的生物现象还原称简单的组成部分(细胞或分子)就能充分解释生物现象的观点有失偏颇.分子与整体,微观与宏观必须结合与统一,这一点已显得日益重要和紧迫.由此,生理学作为一门相对古老的研究结构与功能关系,尤其是整体功能的生命学科,在这一时期获得了新的契机.     

Putting It on the Line: Telephone Counseling for Adolescent Smokers

Adolescent smokers need cessation help, but the question of how best to intervene remains unanswered. This article describes the empirically validated protocol of an established, well‐utilized adolescent telephone counseling program for smoking cessation, tailored to adolescent developmental needs and shown to increase clients' 6‐month prolonged abstinence rate significantly. Clinical issues addressed include client assessment, motivation, self‐efficacy, familial and social support, planning, coping, relapse‐sensitive call scheduling, and self‐image. Counselor training considerations are also discussed.     

Recognizing faces defined by texture gradients

Texture gradients can reveal surface orientation in a manner similar to shape from shading, and therefore provide an important cue for object recognition. In this study, we tested whether a complex 3-D object, such as a face, can be identified from texture gradients alone. The stimuli were laser-scanned faces for which the texture element was a fractal-noise pattern mapped onto the 3-D surface. An eight-alternative forced choice task was used in which participants matched a face defined by texture gradients to one of eight faces defined by shape from shading (Experiment 1) or by texture gradients (Experiment 2). On average, participants scored 24% and 18%, respectively, above chance in these experiments. Although this performance was much poorer than the performance based entirely on shape-from-shading stimuli (Experiment 3), the results suggest that texture gradient information may be used to recover surface geometry of complex objects.     

视觉归纳概括的加工机制与策略

给22名被试呈现若干组在外形与纹路上变化的电池图片,要求指出何种类型的电池有电.结果发现,被试会快速觉察电池的共享特征并概括出一般性的结论.如若电池间无共享特征,被试则需较长时间才给出"无法概括"的反应.共享纹路时,被试在"共享-无干扰"条件下的反应明显快于 "共享- 有干扰"条件下的反应,体现出假设形成与验证的过程.共享特征为外形的反应时短于共享特征为纹路的反应时 ,这说明被试在任务中采用的是整体优先的加工策略.     

领导干部的人格特点与工作绩效的关系：QZPS与NEO PI-R的比较

研究旨在探讨基层党政领导干部的人格特点与工作绩效之间的关系。中国人人格量表（QZPS）测量的人格的七个维度及其18个次级因素均与工作绩效的维度存在不同程度的相关,其中处世态度、人际关系和外向性与任务绩效绩效相关最高,处世态度、情绪性和行事风格与个人品质绩效绩效相关最高,而情绪性与他人评定绩效相关最高。人格因素可以解释自我评定绩效31. 7% ~ 49. 9%的变异,可以解释他人评定绩效6. 3% ~ 12. 8%的变异。而采用NEO PI-R测量人格时,所解释的工作绩效的变异只有QZPS的1/3左右。文中还讨论了工作绩效和人格结构的文化意义以及本土化研究的重要性     

负面身体自我女性对身体信息的记忆偏向： 来自ERP研究的证据

采用事件相关电位（ERPs）技术探讨了负面身体自我女性（大学生）对胖-瘦两类身体图片进行再认时的脑内时程动态变化。结果发现,相对于控制组（正常女大学生）,胖负面身体自我女大学生在750~800ms的时间窗口内,“胖图”比“瘦图”诱发出一个更正的ERP波形,差异波的地形图显示该正成分在中前部有更强的激活。进一步对差异波作偶极子溯源分析,结果发现,该正成分主要起源于右侧枕叶附近。这似乎表明,右侧枕叶的激活与身体自我信息的出现有关,与负面身体自我图式的体验有关     

北京市流动儿童自尊的发展特点及其与学业行为、师生关系的相关研究

以北京市1018名流动儿童和319名城市儿童为被试,用问卷法,考察北京市流动儿童自尊的发展特点,并探讨学业行为、师生关系对流动儿童自尊的影响.结果表明:(1)流动儿童的自尊发展水平存在显著的年级差异;(2)流动儿童的自尊发展水平显著低于城市儿童,两者在高分组(＞41)和低分组(＜28)所占比例分别为39.8%、60.2%和92.7%、7.3%,差异显著;(3)流动儿童的自尊发展水平存在显著的校际差异,混合公立学校流动儿童的自尊发展水平显著高于打工子弟学校的流动儿童;(4)流动儿童的自尊与学业行为、师生关系的各维度均有显著相关,学业行为中的学习效能感、学习自信心和师生关系中的低冲突性、支持性、关系满意度可以显著预测流动儿童的自尊发展水平.     

Psychologists in Academic Health Centers and Medical Centers: Being Visible,Relevant and Integral

Psychologists play key roles in academic health centers. This article is an outgrowth of a presentation at the 2015 Conference of the Association of Psychologists in Academic Health Centers addressing various strategies by which psychologists can effectively adapt to and develop successful careers in medical schools, academic health centers, and teaching hospitals. The authors encourage early career and mid-career psychologists in academic health centers to be active, engaged members of their institutions and to participate in multiple aspects of the research, educational, and clinical missions.     

Cloninger's Temperament and Character Inventory Correlates with Personality Characteristics of Organ Donation Advocates

Temperament and Character Inventory (TCI) and background questionnaire data were collected from a sample of men and women organ donation advocates (N = 362) as part of a national study to investigate their personality characteristics, temperaments, and attitudes about organ donation advocacy. Goals included identifying unique traits for advocates, and response consistency between the TCI and questionnaire. The TCI results included high scores on Cooperativeness and Self-Directedness, and low on Harm Avoidance dimensions. The questionnaire results indicated that most advocates were White, married, college-educated females, who typically spent less than 2 hr with potential donor families, were satisfied with life and job, and believed they would be in a donation position 2 years from the time surveyed. TCI and questionnaire measures were correlated for Self-Transcendence and Spirituality, Helpfulness and Job Satisfaction, and Compassion and Identification variables.     

Task-effector asymmetries in a rhythmic continuation task

Variability in rhythmic movements has been interpreted as a signature of internal or peripheral noise processes. Grounded in an oscillator interpretation, this study hypothesized that period variability and drift arises from the asymmetry between target period and the limb's intrinsic dynamics. Participants synchronized to 7 target periods, swinging 1 of 3 pendulums in a continuation paradigm; 3 periods were longer, 3 shorter, and 1 identical to the preferred period. Results supported 5 predictions: Drift toward the preferred period was observed that scaled with the asymmetry. Variability was lowest for symmetry conditions and increased with the asymmetry. Variability decreased concomitant with the approach toward the preferred period. Periods exponentially approached the preferred period with positive autocorrelations up to 10 cycles.
