真诚型领导能否打破员工沉默?一个有调节的中介模型

本文以进化心理学理论和个体-情景交互理论为基础,并以河南省一家国营企业的222名员工为样本,检验了真诚型领导行为抑制员工沉默行为的影响模型。研究结果表明:真诚型领导行为对员工沉默行为具有显著的负向影响;员工的心理安全感在真诚型领导行为和员工沉默行为之间起着中介作用;员工的外向性和责任感越高,心理安全感与员工沉默行为之间的负向联系的就越强,同时心理安全感的中介效应也越强。本文最后探讨了研究的理论和实践意义以及未来的研究方向。。     

父母控制、自尊与小学生社会创造力的关系

考察父母行为控制、心理控制与社会创造力间的关系、以及自我肯定、自我贬低在其中的中介作用,采用小学生社会创造力测验,父母控制量表和自尊量表对540名5、6年级学生进行研究。结果发现:(1)父母行为控制正向预测社会创造力(γ=0.18),心理控制负向预测社会创造力(γ=-0.28);(2)行为控制通过自我肯定的完全中介作用影响社会创造力(中介效应值为0.09),心理控制则通过自我贬低的部分中介作用影响社会创造力(中介效应值为0.05),模型的总解释率R2=0.20。     

The effect of context and drivers’ age on highway traffic signs comprehension

Background: Comprehension of traffic signs is crucial to safety. Objectives: To test the effects of the presentation condition (with or without driving context) on symbolic based road signs comprehension and comprehension time for young and older drivers. Method: 50 young drivers and 50 older drivers were presented with images of 28 Israeli road signs, both without context (with a white background) and in context (with the driving surrounding). Data were collected on the accuracy of signs meaning and on the time it took the participants to provide the meaning. Results: Younger drivers performed significantly better than older drivers on both accuracy and response time (RT). Older drivers’ average RT was approximately twice as long as younger drivers’ RT. However, the presentation mode (with or without context) did not affect sign comprehension of either group, but the presence of the context did increase the time it took the drivers to comprehend the sign’s meaning. In addition, correct response time was similar to opposite to sign’s meaning response time. Implications: Older drivers, can benefit from retraining in sign comprehension of current signage. The training should involve signs in their natural road environment to reduce comprehension time while actually driving. Moreover, signs that were understood as having an opposite meaning should be redesigned or be accompanied by text.     

Effects of Prevent-Teach-Reinforce on Academic Engagement and Disruptive Behavior

This study assessed the effectiveness of prevent-teach-reinforce (P-T-R), a functional behavioral assessment-based intervention for students with behavior problems, using an A-B-A-B design with follow-up. Participants included three students in kindergarten, fourth grade, and fifth grade in a rural Midwestern school district. P-T-R interventions were implemented with fidelity by all teachers and P-T-R was associated with mean decreases in disruptive behavior for all participants with Tau-U effect sizes ranging from minimal to strong. All three participants demonstrated mean increases in academic engagement with strong effect sizes. P-T-R interventions were associated with moderate to high levels of perceived social validity. Implications for consistent and efficient FBA-based interventions in schools are discussed.     

The psychological construal of health behaviors

IntroductionIn order to optimize the effectiveness of behavior change interventions, we need to understand how the construal level – how we mentally represent or construe events or behaviors – influences health-related choices.ObjectiveTo examine the impact of mental construal on health decisions. Based on the Construal Level Theory, we predicted that people would give more weight to “cognitive considerations” when making a choice after being primed with the high-level perspective, whereas they would give higher weights to “sensory considerations” after being primed with the low-level perspective.MethodIn the first experiment, ninety-nine participants were primed with either high-level or low-level perspective across decision scenarios about vaccination and physical safety. The second experiment investigated nutrition decisions, which asked seventy participants to taste food that either had no label or was labelled “organic”. Organic label should prime high-level construal as it implies outcomes (e.g., product quality and healthiness) that are more distant in time and uncertain, in contrast with sensory dimensions (e.g. taste and appearance), which are immediately present. Participants rated cognitive and sensory considerations as well as action intentions.ResultsThe first study revealed that after the priming with the high-level construal, cognitive considerations became more important than sensory considerations in predicting protective action intentions, whereas after priming with the low-level construal, sensory considerations became more important. The second study revealed that only sensory considerations predicted decisions to consume the non-labelled product and only the cognitive score predicted decisions to consume the organic-labelled product.ConclusionWe demonstrated a moderating effect of construal-level mindset in health-protective decisions. We also discuss the implications for health promotion and policy, such as optimizing the effectiveness of behavior change interventions.     

Recent advances in applied research on DRO procedures

Differential reinforcement of other behavior (DRO) has been applied to reduce problem behavior in various forms across different populations. We review DRO research from the last 5 years, with a focus on studies that enhance our understanding of the underlying mechanisms of DRO. We also discuss implications for practitioners and applied researchers.     

Additional free reinforcers increase persistence of problem behavior in a clinical context: A partial replication of laboratory findings

Behavioral momentum theory is a quantitative framework used to characterize the persistence of behavior during response disruptors as a function of baseline stimulus–reinforcer relations. Results of several investigations have shown that alternative reinforcement can increase the resistance to change of a target response during extinction. In the present study, concomitant variable‐interval fixed‐time schedules of reinforcement for problem behavior were employed to simulate naturalistic situations involving the superimposition of response‐independent reinforcers on a baseline schedule of reinforcement for problem behavior, as in the common use of noncontingent reinforcement treatments. Resistance to change of problem behavior was assessed during postsession periods of extinction by comparing response rates in extinction following sessions with and without additional reinforcer deliveries arranged by fixed‐time schedules. For 2 out of 3 participants, problem behavior tended to be more resistant to extinction following periods in which additional fixed‐time reinforcers were delivered. These results are discussed in terms of potential effects of noncontingent reinforcement on problem behavior when the intervention is discontinued or implemented without good treatment integrity.
