Stimulus control and delayed reinforcement

Pigeons were tested for generalization along the line-orientation dimension, after being trained on various two-component multiple schedules. The first component contained either a variable-interval 1-min schedule of immediate reinforcement or an extinction schedule and was associated with a plain white key (S1). The second component contained a variable-interval 1-min schedule of delayed reinforcement and was associated with a black line on a white background (S2). The major results showed that (a) decremental gradients were obtained around the stimulus associated with the delayed reinforcement component when S1 was associated with extinction, but that incremental gradients were obtained when S1 was associated with immediate reinforcement, (b) the subjects' pretraining did not affect the generalization gradients if sufficient training on the terminal multiple schedule was provided, and (c) changing the S1 schedule from immediate reinforcement to extinction produced behavioral contrast if reinforcement was delayed for 10 sec during S2, but not if it was delayed for 20 sec.     

不规则几何图形识别的取样首视点研究

用实验方法对不规则几何图形的取样首视点进行研究。作业任务有认同与匹配二种,显示条件有良好与不良二种,显示方式有旋转与不旋转二种,绩效指标用反应时与错误指数二项。结果表明：首视点的分布是非均匀的,落在轮廓部位的概率最大,落在中央或某条特定边的概率极小。首视点分布的均匀度与作业难度有关,在作业难度较大的情况下,首视点分布趋于集中。多数情况下,首视点的置位对作业绩效的影响不大。     

On Becoming a Cybernetician: Highlights and Milestones

In this article, I describe how I encountered cybernetics and how it became an important part of my life. I begin with an account of my time at Brunel University and also describe how I came to work with Gordon Pask, one of the few intellectuals and researchers in the UK who styled themselves as cyberneticians. To enrich my story, I include an overview of the story of cybernetics as I perceive it. Given the importance I attach to cybernetics as an intellectual tool, I end with a plea for it to be included in all educational curricula.     

Using Curriculum-Based Measurements for Program Evaluation: Expanding Roles for School Psychologists

Educators increasingly need to evaluate schoolwide reform efforts; however, complex program evaluations often are not feasible in schools. Through a case example, we provide a heuristic for program evaluation that is easily replicated in schools. Criterion-referenced interpretations of schoolwide screening data were used to evaluate outcomes associated with participation in four-year-old kindergarten. Nonparametric analyses allowed for group comparisons across early literacy screening outcomes. Risk ratios demonstrated that four-year-old kindergarten participants were less likely to score “at-risk” on kindergarten and first grade screenings. The methods employed meaningfully addressed local program effectiveness questions. Further, they were easily determined and disseminated. Implications for extensions of the heuristic to other evaluation questions and data sources as well as limitations of the approach are discussed.     

Empathy and transformative experience without the first person point of view (a reply to L. A. Paul)1

Abstract

In her very interesting ‘First-personal modes of presentation and the problem of empathy’ (2017, 315–336), L. A. Paul argues that the phenomenon of empathy gives us reason to care about the first person point of view: that as theorists we can only understand, and as humans only evince, empathy by appealing to that point of view. We are skeptics about the importance of the first person point of view, although not about empathy. The goal of this paper is to see if we can account for empathy without the ideology of the first person. We conclude that we can.     

Substance Use Assessment Instruments: 13 Years Later

The authors surveyed Master Addiction Counselors and members of the International Association of Addictions and Offender Counselors (N = 131) about their use of substance use disorder and process addiction screening and assessment instruments. The results are compared with those of Juhnke, Vacc, Curtis, Coll, and Paredes ( 2003 ).     

人事筛选和挑选决策策略的比较

本研究采用了多特征决策研究中的过程追踪技术,对人事筛选和挑选决策的策略进行了单步跳转和多步跳转分析与比较。结果发现,在人事挑选时,被试更多采用基于方案的补偿性策略,并以有关合适人选的心理映像为标准做出决策;而筛选时更多采用基于特征的非补偿策略以减少认知负荷,同时,以方案间比较为目的的补偿性策略也更多使用。这些策略变化体现了决策者的认知适应性。     

The Reliability and Validity of a Brief Self-Report Questionnaire to Screen for Mental Health Problems: The Health Dynamics Inventory

Mental health problems are underrecognized in medical settings, leading to inadequate treatment. The present paper describes the development of the Health Dynamics Inventory (HDI), a brief, self-report questionnaire developed to evaluate mental health functioning. The HDI was written to evaluate the three aspects of mental disorders as described in the Diagnostic and Statistical Manual of Mental Disorders (DSM): (1) the experience of emotional or behavioral symptoms; (2) emotional distress; and (3) psychosocial impairment. This study evaluated the psychometric properties and construct validity of its items, scales, and subscales. Results indicated that the items distinguish patients from nonpatients, that the instrument's scales and subscales are reliable, and that the scales and subscales discriminates between persons with mental health concerns or diagnosable problems and those without such concerns or problems. The utility of the instrument for screening mental health problems in primary care settings is discussed.     

耐多药肺结核患者首次就诊过程调查

了解现阶段耐多药肺结核患者的首次就诊过程,分析医患双方对耐多药肺结核患者就诊过程的影响。在全国选取5个项目市,使用自制调查问卷采取面对面方式对样本人群进行访谈式调查。耐多药肺结核患者以文化水平较低、年龄偏大的农民为主。32.6%的患者初次就诊时有全身乏力或消瘦症状,37.6%的患者初次就诊单位为村卫生室或乡镇卫生院,28.4%的患者初次就诊时被误诊,31.6%的患者发生就诊延迟,79.8%的患者在结核病专科医院或防治机构确诊,33.3%的患者确诊延迟。加大对群众结核病相关知识宣传力度,加强结核病防治机构技术力量尤其是实验室诊断技术,加强对参与结核病防治工作医生尤其是村医的专业培训,针对医疗机构转诊建立适当的激励机制。
