The role of the psychologist expert witness: Provider of perspective and input

The definition and role of the expert witness is reviewed. Two conceptual systems for viewing the world, the scientific method and the adversarial system, are compared. The reconciliation and integration of these two discrepant systems are discussed in terms of input versus outcome. The rules of evidence, as well as problems of communication between the systems, are reviewed with the aim of providing expert witnesses with a better understanding of effective testimony. Finally, collaboration between the two systems is called for in order to provide guidelines for both neuropsychologists and attorneys.     

Thoughts and feelings and things: A new psychiatric epistemology

Epistemology — the study of knowledge — is a philosophical discipline with close ties to psychiatry. When epistemologists address specific questions about how knowledge is actually realized by human beings, their philosophy must be informed by empirical studies of the sort psychiatrists now take up in a variety of forms. As this paper describes, psychiatrists can likewise improve their understanding of human psychology through a deeper appreciation of philosophical analysis in epistemology.The aim of this article is to introduce a unifying framework within which the experience from different approaches to psychiatry — (1) the conceptual schemas of cognitive psychiatry, (2) the mental structures of psychoanalytic psychiatry, (3) the categorical forms of existential psychiatry, and (4) the neural pathways of biological psychiatry — can all be applied productively to the central question of epistemology. By establishing a broad understanding of the problem of knowledge, this new view of epistemology is developed within the idiom of each psychiatric approach. In addressing themselves to a unitary problem, these diverse psychiatric approaches are themselves revealed, not as competing points of view, but as complementary views of a single subject. The result is a new epistemology that can not only bring the insights of psychiatry to philosophy, but can also contribute to the care of patients when psychiatrists bring this broader view to their clinical work.     

Control of responding by location of auditory stimuli: adjacency of sound and response.

Four rhesus monkeys were trained to respond on one key when a one-second noise burst was presented through one speaker and to respond on a second key when the noise burst was presented through a second speaker. The acquisition of stimulus control was studied under three conditions, in each of which the relationship between the sound source and the response-key positions varied: an adjacent condition in which the noise burst was presented through the key and a response on this key was reinforced; a reversed-adjacent condition in which the noise burst was presented through one key and responding on the other key was reinforced: and a nonadiacent condition in which responding on the key nearer the sound was reinforced. Under adjacent conditions, stimulus control developed within one or two sessions. Under reversed and nonadjacent conditions, 10 sessions were required for the development of control. The asymptote of correct responding was the same under each condition in all animals.     

Fitting cross-classification table data to models when observations are subject to classification error

Individuals are classified in a cross-classification table where two behavioral observations on each individual determine the classification. The problem is to test certain structural models assumed to underlie the cross-classified observations. A minimum chi-square test procedure is proposed.     

得失情境下他人参照点及心理距离对自我-他人利益权衡的影响

以福利权衡率(WTR)为利他程度的指标,通过3个实验逐步深入地考察了得失情境下他人参照点及心理距离对自我-他人利益权衡的影响。实验1的结果表明,得失情境并未改变被试的WTR。实验2引入他人底线、现状和目标三个参照点变量,发现被试获益情境下的WTR高于损失情境,且WTR从高到低依次为他人临近底线、目标和现状;他人临近底线时,被试在获益情境下的WTR高于损失情境,而他人临近现状和目标时,个体在得失情境下的WTR无显著差异。实验3进一步引入心理距离变量,发现心理距离较近他人的WTR高于较远他人,且与得失情境和参照点发生了复杂的交互效应,得失情境的主效应消失了,但总体上并未改变实验2发现的参照点效应。这些结果对于更深入地理解得失不对称效应、三参照点理论及社会折扣和自我-他人决策差异研究的相关发现具有一定的启示意义。

人工智能辅助下的心理健康新型测评

近年来,人工智能技术的飞速发展及应用催生了"智能化心理健康测评"这一领域。智能化心理健康测评能够弥补传统方法的不足,降低漏诊率并提高诊断效率,这对于心理健康问题的普查及预警具有重大意义。目前,智能化心理健康测评处于初步发展阶段,研究者基于在线行为数据、便携式设备数据等开展主要以数据驱动为导向的探索研究,旨在实现更高的预测准确率,但是测评结果的可解释性等指标尚不够理想。未来的智能化心理健康测评需要强调心理学领域知识和经验的深度介入,提高测评的针对性和精细化程度,加强信效度检验,这对于智能化心理健康测评工具的进一步发展和应用至关重要。     

初级军官心理选拔的预测性

目的：通过建立院校学员胜任特征及初级军官评价模型,探讨初级军官心理选拔检测系统的预测性。方法：某军校340名男性本科学员入校时完成初级军官心理选拔检测,毕业前进行院校胜任特征评价,对162名学员毕业后1~5年进行部队工作表现追踪评价。结果：中国MBTI-G人格类型测验对院校学员管理能力、影响力、约束力、口头表达、军人气质、人际关系等有较好的预测性,预测符合率72.13%;中国军人明尼苏达个性调查表6项精神障碍维度对情绪稳定性有较好的预测,预测符合率71.90%;院校学员一般能力倾向测验对学业成绩、文字表达、口头表达、人际关系和决策能力等胜任特征也有一定的预测性,预测符合率66.70%;三项测验院校胜任特征总预测符合率达81.70%,部队胜任特征总预测符合率76~87%。结论：为我军初级军官心理选拔提供了实用工具,为提高心理选拔预测准确性提供了科学依据     

Are All Kids Alike? The Magnitude of Individual Differences in Personality Characteristics Tends to Increase from Early Childhood to Early Adolescence

Do individual differences in personality traits become more or less pronounced over childhood and adolescence? The present research examined age differences in the variance of a range of personality traits, using parent reports of two large samples of children from predominantly the USA and Russia, respectively. Results indicate (i) that individual differences in most traits tend to increase with age from early childhood into early adolescence and then plateau, (ii) that this general pattern of greater personality variance at older childhood age is consistent across the two countries, and (iii) that this pattern is not an artefact of age differences in means or floor/ceiling effects. These findings are consistent with several (noncontradictory) developmental mechanisms, including youths' expanding behavioural capacities and person–environment transactions (corresponsive principle). However, these mechanisms may predominantly characterize periods before adolescence, or they may be offset by countervailing processes, such as socialization pressure towards a mature personality profile, in late adolescence and adulthood. Finally, the findings also suggest that interpreting age trajectories in mean trait scores as pertaining to age differences in a typical person may sometimes be misleading. Investigating variance should become an integral part of studying personality development. Copyright © 2017 European Association of Personality Psychology     

大中小学生内隐序列学习的发展性研究

采用序列学习的研究范式,对大中小学生的序列反应时和序列生成成绩进行测量,结果表明:(1)大中小学生均能在序列学习中获得序列规则。(2)采用比例测量方法,大中小学生的序列反应时无显著差异。(3)大中小学生的序列生成成绩是不同的,包含成绩随着年级升高而上升,排除成绩则不随年级变化;小学生包含和排除成绩无显著差异,而中学生和大学生的差异逐渐加大。说明序列学习的意识成分随年级的升高而增加。
