The performance and observation of action shape future behaviour

The observation of other people’s actions plays an important role in shaping the perceptual, cognitive, and motor processes of the observer. It has been suggested that these social influences occur because the observation of action evokes a representation of that response in the observer and that these codes are subsequently accessed by other cognitive systems to modify future behaviour. In the case of social search and movement tasks, the observation-evoked response code is thought to activate the same mechanisms that are activated following internally-generated response codes. In support of this hypothesis, the present study revealed that the magnitudes of the between-person inhibition of return (IOR) effects were correlated with within-person IOR effects. These findings provide substantial support for the link between observation-evoked response codes and social cognitive effects.     

Deficits in executed and imagined aiming performance in brain-injured children

Motor disorders are a frequent consequence of acquired brain injury (ABI) in children and much effort is currently invested in alleviating these deficits. The aim of the present study was to test motor imagery (MI) capabilities in children with ABI (n=25) and an age- and gender-matched control group (n=25). A computerized Virtual Radial Fitts Task (VRFT) was used to investigate the speed-accuracy trade-offs (or Fitts' law) that occur as target size is varied for both executed and imagined performance. In the control group, the speed for accuracy trade-off for both executed and imagined performance conformed to Fitts' law. In the ABI group, only executed movements conformed to Fitts' law. These findings suggest that children with ABI show an inferior ability to imagine the time needed to complete goal-directed movements with differential difficulty levels.     

超越个体：组织公民行为跨层次研究

以往的研究认为组织公民行为是个人行为,并且大多数研究是在个体层次上展开的。事实上,由于组织中的个体嵌入在群体和组织中,组织公民行为会受到群体和组织等不同层次因素的影响。本文从层次问题入手,对国外文献深入系统研究的基础上,对组织公民行为的研究层次和研究模型进行梳理,以期明晰组织公民行为的层次研究现状,并在此基础上探讨中国本土化情境下开展组织公民行为跨层次研究的必要性和可行性。     

微观发生法:聚焦认知变化

微观发生法通过在变化发生的整个过程中对行为进行高密度观察和反复试验分析,可以提供关于认知变化的路线、速率、广度、来源以及变化模式的多样性等方面的精细信息,对于理解心理变化的机制有重要意义。该文论述了从发生法到微观发生法的演变过程、微观发生法的研究设计及其合理性与有待解决的问题。     

Pragmatic post‐structuralism (I): participant observation and discourse in evaluating violence intervention

This paper discusses the process and merits of a post‐structuralist approach to participant observation and describes the use of this research strategy in evaluating a community based ‘stopping violence’ programme. While the participant observation research strategy is commonly employed as a ‘process evaluation’ method (Rossi and Freeman, 1993 ) it's role within a distinctly post‐structuralist programme is a novel application of a well‐established research strategy. This has significant implications for how social scientists may approach both participant observation and evaluation in the future. Copyright © 2001 John Wiley & Sons, Ltd.     

父母婚姻冲突、不良同伴交往对初中生攻击行为的影响:一个有调节的中介模型

采用问卷法对1406名初一学生进行调查,考察了不良同伴交往在父母婚姻冲突与初中生攻击行为关系间的中介效应,以及冲动性对这一中介过程的调节效应。结果发现:(1)在控制了性别、年龄、家庭人均月收入和父母受教育水平之后,婚姻冲突显著正向预测青少年攻击行为;(2)不良同伴交往在婚姻冲突与攻击行为关系间起着显著的部分中介作用;(3)冲动性对中介路径"婚姻冲突→不良同伴交往→攻击行为"具有显著的调节效应。     

The General Behavior Inventory as an outpatient screen for dysthymic disorder

High prevalence, morbidity, and response to treatment make the detection of dysthymic disorder an important public health issue. We report our experience with the General Behavioral Inventory, a self-report questionnaire developed to detect affective illness, including dysthymic disorder. In a small sample of psychiatric outpatients the instrument yielded a sensitivity of 61% and a specificity of 88% for dysthymic disorder. These results challenge the utility of this instrument for detecting dysthymic disorder in this population.This work was supported in part by Grants MH-19069 and MH7103 from the National Institutes of Mental Health.     

Behavioral case consultation with parents and teachers: An example using differential reinforcement to treat psychogenic cough

This study presents a demonstration of successful behavioral case consultation combined with case study methodology in the treatment of a 13-year-old female who presented with a brief history of psychogenic cough. Psychogenic cough is diagnosed when there is no organic or physiologic basis for the repeated, harsh coughing. We first present a brief review of treatments for psychogenic cough and then describe how we used differential reinforcement of low rate responding (DRL) and differential reinforcement of zero responding (DRO) within an A-B-C design. The DRL schedule produced significant decreases in coughing but plateaued at about one-third the baseline rate. Thereafter, a DRO schedule was employed which resulted in complete and lasting elimination of coughing. Discussion focuses on the limitations of case study methodology as well as its usefulness for conducting service related research in the schools, implications of some of the findings for practitioners, and other issues related to treatment.     

IMPLICATIONS OF BEHAVIORAL PHARMACOLOGY RESEARCH FOR APPLIED BEHAVIOR ANALYSES: JEAB'S SPECIAL ISSUE CELEBRATING THE CONTRIBUTIONS OF JOSEPH V. BRADY (MARCH 1994)

We review four articles from JEAB's March 1994 issue celebrating the contributions of Joseph V. Brady. These articles have implications for studying private events and for studying multiple operants. We suggest that regularly including self-reports about private events in behavioral pharmacological research has resulted in an accumulated knowledge that has facilitated examination of interesting relations among self-reports, environmental factors, and other observable behaviors. Methodological lessons that behavioral pharmacologists have learned regarding the study of multiple operants are also relayed. We provide examples of how these lessons could be useful to applied behavior analysts studying nonpharmacological issues.     

Some empirical justification for a modest proposal regarding data acquisition via intermittent direct observation

Computer simulations of behavior and event records of a child's visual fixation on an adult person were generated and sampled using a modified time sampling procedure. The modified approach required making two independent scoring judgments per observation interval: if the behavior was initiated within the interval, the interval was scored; if the behavior was ongoing precisely at the end of the interval, the interval was again scored. The results showed that the within-interval and end-of-interval scores yielded, respectively, estimates of behavioral frequency and duration. The accuracy of the estimates was a function of the number of observations. Several field studies demonstrated high agreement among observers who employed the measurement system.
