Teaching Students to Recruit Positive Attention: A Review and Recommendations

Positive teacher attention and praise are powerful influences on student performance in the classroom. But the classroom is a very busy place, a place where important efforts by students can easily go unnoticed. In such instances, an existing and potentially effective natural contingency of reinforcement is asleep and needs to be woken up. Teaching students how to recruit positive teacher attention is one way to activate dormant contingencies of reinforcement and help students take a proactive role in their learning. This paper reviews the recruiting research to date, discusses implications for practitioners, proposes a recruitment training package including strategies for promoting generalization of recruiting skills, and offers recommendations for future research.     

Using Behavioral Skills Training to Promote the Generalization of Parenting Skills to Problematic Routines

Research has demonstrated the efficacy of a behavioral parent training program for skills acquisition; however, few studies have examined the extent to which those skills generalize to the home or the effect that they have on child behavior. A multiple baseline across participants design was used to assess (a) caregiver accuracy with implementation of three parenting skills, and (b) the effects of the parenting skills on child behavior. Results demonstrated that three caregiver participants successfully generalized parenting skills taught during behavioral skills training (BST) to naturally occurring routines, and the behavior of each caregiver's child improved following BST.     

Evaluation of a lag schedule of reinforcement in a group contingency to promote varied naming of categories items with children

We compared the effects of Lag 0 and Lag 1 schedules of reinforcement on children's responses naming category items in a group context and subsequent responses emitted during individual testing in which the schedule of reinforcement remained Lag 0. Specifically, we measured response variability and novel responses to categories for 3 children who demonstrated the lowest level of variability during an initial individual Lag 0 testing session. An additional 3 children who emitted a high level of variability during initial individual Lag 0 testing sessions served as peers during group sessions. Results showed that participants conformed to the Lag 1 schedule and were more likely to repeat peer responses in the group and during individual testing in the Lag 1 condition. Furthermore, the reinforcement schedule in effect during group sessions affected participants’ varied responses during individual testing, during which the reinforcement schedule remained unchanged.     

The effects of categorical similarity and feature-space proximity on visual working memory processing

Two patterns of data predict that similarity has a positive effect and a negative effect on visual working memory (VWM) processing. We assume that these two empirical outcomes do not distinguish categorical similarity from feature-space proximity, resulting in this divergence. To investigate how categorical similarity and feature-space proximity modulate VWM, we tested memory for an array of pictures drawn from either mixed categories or a single category in which feature-space proximity varied along a morph continuum in a change-detection task. We found that memory under the mixed-category condition was better than that under the single-category condition, whereas memory under high feature-space proximity was superior to that under low feature-space proximity. These patterns were unaffected by manipulations of stimulus type (faces or scenes), encoding duration (limited or self-paced), and presentation format (simultaneous or sequential). These results are consistent with our hypotheses that categorical similarity inhibits VWM, whereas feature-space proximity facilitates VWM. We also found that memory for items with low feature-space proximity benefited more from mixed-category encoding than that for items with high feature-space proximity. Memory for faces benefited more from mixed-category encoding than scenes, whereas memory for scenes benefited more from feature-space proximity than faces. These results suggest that centre-surround inhibition organization might underlie similarity effects in VWM. Centre-surround inhibition organization for complex real-world objects could have both categorical level and feature-space level. The feature-space level might differ by category.     

Multiple schedules,off‐baseline reinforcement shifts,and resistance to extinction

Resistance to extinction in a target multiple‐schedule component varies inversely with the rate of reinforcement arranged in an alternative component during baseline. The present experiment asked whether changing the reinforcer rate in an alternative component would impact extinction of target component responding if those changes occurred in an off‐baseline phase during which the target component was never experienced. Pigeons' key pecking was studied in three types of conditions, and each condition consisted of three phases. In Phase 1, pecking produced food in the target and alternative components of a multiple schedule according to variable‐interval 60‐s schedules. In Phase 2, the alternative‐component stimulus was presented alone in a single schedule. Pecking during this phase produced the same reinforcer rate as in baseline in the Control condition, a higher rate of food (variable‐interval 15 s) in the High‐Rate condition, or was extinguished in the Extinction condition. Extinction of target‐ and alternative‐component key pecking then was assessed in a multiple schedule during the final phase of each condition. Resistance to extinction of target‐component key pecking was the same between the Control and High‐Rate conditions but lower in the Extinction condition. These findings are discussed in terms of discrimination and generalization processes.

Clustering preference data in the presence of response-style bias

Preference data, such as Likert scale data, are often obtained in questionnaire-based surveys. Clustering respondents based on survey items is useful for discovering latent structures. However, cluster analysis of preference data may be affected by response styles, that is, a respondent's systematic response tendencies irrespective of the item content. For example, some respondents may tend to select ratings at the ends of the scale, which is called an ‘extreme response style’. A cluster of respondents with an extreme response style can be mistakenly identified as a content-based cluster. To address this problem, we propose a novel method of clustering respondents based on their indicated preferences for a set of items while correcting for response-style bias. We first introduce a new framework to detect, and correct for, response styles by generalizing the definition of response styles used in constrained dual scaling. We then simultaneously correct for response styles and perform a cluster analysis based on the corrected preference data. A simulation study shows that the proposed method yields better clustering accuracy than the existing methods do. We apply the method to empirical data from four different countries concerning social values.     

提问类型对自传体记忆概括化的影响

自传体记忆概括化程度较高是抑郁症产生与发展的重要影响因素, 探究降低自传体记忆概括化程度的方法以缓解抑郁症状、降低抑郁复发率是心理咨询与治疗中的一个重要研究课题。基于此, 本研究选取344名初中生进行实验, 实验1对比了问题状态组与正常状态组被试的自传体记忆概括化程度, 结果发现, 问题状态组被试的正性、负性自传体记忆得分均显著低于正常组, 两组在中性自传体记忆得分上差异不显著; 实验2对比了问题取向提问和解决取向提问对问题状态下人们自传体记忆概括化程度的影响, 结果发现, 解决取向提问组被试无论是在正性、负性自传体记忆得分上还是在中性自传体记忆得分上均显著高于问题取向提问组和控制组, 问题取向提问组和控制组在各类自传体记忆得分上差异均不显著; 实验3进一步考察了解决取向提问对问题状态下不同归因风格者自传体记忆概括化程度的影响, 结果发现, 内归因组被试的正性、负性自传体记忆得分均显著高于外归因组, 在中性自传体记忆得分上, 两组被试间差异不显著。结论:与抑郁症等精神障碍患者类似, 遭受一般心理困扰个体的自传体记忆概括化程度也较高; 相比问题取向提问, 解决取向提问能较好地降低一般心理困扰者的自传体记忆概括化程度; 对于一般心理困扰者而言, 解决取向提问对内归因者自传体记忆概括化程度改善效果优于外归因者。综上, 解决取向提问可以作为心理咨询师或治疗师降低个案自传体记忆概括化程度的一种有益尝试。
