想象膨胀范式下错误记忆的老化效应

通过2个实验探究想象膨胀范式下老年人的错误记忆特点及其认知机制。实验1采用经典想象膨胀实验范式, 考察老年人是否会产生比年轻人更大的想象膨胀错误记忆效应; 实验2引入情景特异性诱导技术, 进一步考察老年人的想象膨胀错误记忆可能的认知机制。研究结果表明：(1)老年人与年轻人均表现出显著的想象膨胀错误记忆, 但老年人并没有比年轻人产生更多的错误记忆; (2)当通过情景特异性诱导技术有效增加了老年人在事件想象过程中的内在细节数量后, 老年人的错误记忆显著上升。该结果揭示对事件情景的想象过程是想象膨胀错误记忆发生的关键环节, 老年人没有表现出明显的老化效应, 主要是由于该群体随年龄增长表现出在回忆/想象情景事件时内部细节缺乏这一特征所致。研究结果支持了建构性情景模拟假说和激活/监测理论。     

Training behavioral technicians to implement naturalistic behavioral interventions using behavioral skills training

Training behavioral technicians mainly focuses on teaching accurate implementation of structured behavioral intervention programs. Often behavioral technicians are unable to adequately promote their clients' learning in less structured environments, which can limit opportunities for generalization of the clients' skills to the natural environment. The aim of the present study was to evaluate the effectiveness of using behavioral skills training to coach behavioral technicians on the implementation of naturalistic behavioral interventions. Naturalistic behavioral interventions take advantage of naturally occurring situations to teach new skills and practice mastered skills in natural settings, thus promoting generalization across environments and in the presence of natural contingencies. Five behavioral technicians were trained to implement a novel protocol based on play therapy. Specifically, they were coached to engage in well‐defined positive behaviors during their interactions with clients (e.g., labeled praise). All participants reached mastery criteria, maintained skills at follow‐up, and demonstrated generalization of skills with novel clients.     

《孙子兵法》中的励士方略与现代激励

随着现代管理思想的发展,“激励”越来越为人所重视。其实中国很早就有“激励”一词,《孙子兵法》中就充满了激励思想和高超的励士方略,如道义激励、感情激励、环境激励、赏罚激励、气势激励、危机激励等,我们应认真学习、领会、借鉴,并与现代西方的激励理论与方法相结合,将其运用于根植在中国传统文化沃土上的中国企业的人力资源管理之中,必将会更加有效。     

MMPI-2 fake-bad scales: an attempted cross-validation of proposed cutting scores for outpatients

Minnesota Multiphasic Personality Inventory-2 (MMPI-2) results were compared in 118 psychiatric outpatients given standard instructions, instructions to exaggerate their problems, instructions to feign a disorder they did not have, or instructions to feign global psychological disturbance. The groups were comparable on demographic, occupational and diagnostic characteristics as well as intake MMPI-2 results. Experimental MMPI-2 results showed that clinical scales were generally elevated in the feigning groups, with only modest differences across dissimulating instruction sets. The feigning groups had reliably higher scores than controls on all overreporting indexes examined, although no significant differences between feigning groups were present for overreporting indexes. Classification rates using previously proposed cutting scores for outpatients on individual feigning indexes showed near perfect specificity, but low to at best moderate sensitivity. Multiple regression analyses indicated that Gough's (1954) Dissimulation Scale (Ds2) was most strongly related to feigning status, and no other feigning scale contributed a significant increment in predictive power once Ds2 was entered.     

Comparison of muscle functions during three contrasting abdominal exercises

That different amplitudes of muscle activities during various abdominal exercises not only reflect the inherent differences in motor control but movement speed as well was hypothesized. 20 healthy adults (M age = 23 yr.) performed three exercises that involved varying amounts of trunk control: the partial sit-up, full sit-up, and AbSlide roll. Covariate analyses indicated that the amplitude of muscle activities could be partitioned into three categories: motor control and scaling (speed and amplitude), scaling only, and motor control only. Overall, the AbSlide exercise activated the most amount of muscular activity, followed by the full and partial sit-up exercises. Results are discussed in terms of how the various muscles contribute to motor control and velocity scaling.     

The “ventriloquist effect”: Visual dominance or response bias?

The interaction between vision and audition was investigated using a signal detection method. A light and tone were presented either in the same location or in different locations along the horizontal plane, and the subjects responded with same-different judgments of stimulus location. Three modes of stimulus presentation were used: simultaneous presentation of the light and tone, tone first, and light first. For the latter two conditions, the interstimulus interval was either 0.7 or 2.0 sec. A statistical decision model was developed which distinguished between the perceptual and decision processes. The results analyzed within the framework of this model suggested that the apparent interaction between vision and audition is due to shifts in decision criteria rather than perceptual change.     

Applications of multivariate visualization to behavioral sciences

The complexity of psychological science often requires the collection and analysis of multidimensional data. Such data bring about a corresponding cognitive load that has led scientists to develop techniques of scientific visualization to ease the burden. This paper provides an introduction to scientific visualization techniques, a framework for understanding those techniques, and an assessment of the suitability of this approach for psychology. The framework employed builds on the notion of balancingnoise andsmooth in statistical analysis.     

Dissociation of reward and effort sensitivity in methcathinone‐induced Parkinsonism

Methcathinone‐induced Parkinsonism is a recently described extrapyramidal syndrome characterized by globus pallidus and substantia nigra lesions, which provides a unique model of basal ganglia dysfunction. We assessed motivated behaviour in this condition using a novel cost‐benefit decision‐making task, in which participants decided whether it was worth investing effort for reward. Patients showed a dissociation between reward and effort sensitivity, such that pallidonigral complex dysfunction caused them to become less sensitive to rewards, while normal sensitivity to effort costs was maintained.
