Resistance to change of operant variation and repetition

A multiple chained schedule was used to compare the relative resistance to change of variable and fixed four-peck response sequences in pigeons. In one terminal link, a response sequence produced food only if it occurred infrequently relative to 15 other response sequences (vary). In the other terminal link, a single response sequence produced food (repeat). Identical variable-interval schedules operated in the initial links. During baseline, lower response rates generally occurred in the vary initial link, and similar response and reinforcement rates occurred in each terminal link. Resistance of responding to prefeeding and three rates of response-independent food delivered during the intercomponent intervals then was compared between components. During each disruption condition, initial- and terminal-link response rates generally were more resistant in the vary component than in the repeat component. During the response-independent food conditions, terminal-link response rates were more resistant than initial-link response rates in each component, but this did not occur during prefeeding. Variation (in vary) and repetition (in repeat) both decreased during the response-independent food conditions in the respective components, but with relatively greater disruption in repeat. These results extend earlier findings demonstrating that operant variation is more resistant to disruption than is operant repetition and suggest that theories of response strength, such as behavioral momentum theory, must consider factors other than reinforcement rate. The implications of the results for understanding operant response classes are discussed.     

Behavioral extremity moderates the association between certainty in attitudes about COVID and willingness to engage in mitigation-related behaviors

People generally intend to act more on beliefs and attitudes about which they have greater certainty. However, we introduce a boundary condition to the positive association between certainty and behavioral intentions—behavioral extremity. Uncertainty about a threatening issue like COVID-19 can be disconcerting, and we propose that uncertain people cope in part through increased openness to extreme actions like accepting risky medical treatments and aggression toward those defying mitigation policies. Testing this, we compiled and analyzed all the data on certainty about COVID-19 mitigation policies and willingness to engage in mitigation-related behaviors that our lab collected during the pandemic (6 samples, 20 behaviors, Ns up to 1496). External ratings of the behaviors' extremity moderated certainty-willingness associations: whereas greater certainty was associated with increased willingness to engage in moderate behaviors (the typical result), lower certainty was associated with increased willingness to engage in extreme behaviors, especially among those worried about becoming ill.     

青少年对广告的态度及影响因素

通过对北京城八区11所中学的730个有效样本的研究分析,作者发现,北京青少年对广告的总体态度比较消极, 40.2%的青少年表示不喜欢广告, 27.9%中立,只有31.9%喜欢广告;此外,61.6%的青少年表示不信赖广告,24%中立,仅14.5%的青少年表示信赖广告。在对广告信念的因子分析中,青少年对广告“决策信息”功能表示基本肯定;对广告的“娱乐”、“购买体验”和“个人伤害”结果表示基本否定。此外,人口统计变量与广告总体态度以及各个因子之间有一定的关系。因此,要改变青少年对广告的消极态度,企业营销者需要从产品质量、广告表现形式、广告诉求内容等多个方面加以改善和提高。     

大学生网络成瘾：背景性渴求与同伴网络过度使用行为及态度的交互作用

基于整体-交互作用模型,选取北京市某高校所有大一学生2511名为被试开展问卷调查,考察了大学生网络使用背景性渴求的特点及其与网络成瘾之间的关系,并就网络使用背景性渴求与同伴网络过度使用行为与态度对网络成瘾的交互作用进行了检验。结果发现:(1)与非网络成瘾大学生相比,网络成瘾大学生的网络使用背景性渴求更高,所感知到的同伴网络过度使用行为更多,同伴对网络过度使用的态度更积极;(2)网络使用背景性渴求各维度、感知到的同伴网络过度使用行为可正向预测大学生的网络成瘾;(3)背景性渴求中的积极结果预期与同伴对网络过度使用的态度对网络成瘾存在显著的交互效应:在低积极结果预期条件下,同伴对网络过度使用的态度可以负向预测网络成瘾程度,而在高积极结果预期条件下,同伴态度对网络成瘾的预测作用不显著。结论:外因在内因比较微弱的条件下发挥更为明显的作用。

Attitudes Toward Religion Scale: development and initial psychometric evaluation among Chinese college students

The Attitudes Toward Religion Scale (ATRS) was developed to access the level of interest in and position toward the five state-approved religions in China. Data were analysed across two samples of Chinese college students. With Sample 1 (N = 278), exploratory factor analyses were used to select the 10 ATRS items corresponding to two factors: Interest and Position. With Sample 2, confirmatory factor analyses (N = 270) cross-validated the two-factor oblique model as well as a bifactor model. Cronbach alphas of ATRS subscale scores in the two samples ranged from .75 to .85. ATRS-Interest and Position were both positively associated with number of close relationships with religious people. In addition, negative attitudes toward religion was associated with being religiously proselytised by strangers. Moreover, female students reported more favourable attitudes toward religion compared to their male counterparts. The overall results support ATRS as a psychometrically strong and promising measure.     

Linking safety knowledge to safety behaviours: a moderated mediation of supervisor and worker safety attitudes

The thousands of deaths and disabilities due to workplace accidents and injuries each year emphasize the importance of safety research. Despite occupational safety research that has contributed to identifying antecedents of safety, little is known about why and how safety knowledge leads to safety behaviours and how personal and situational factors interact to promote occupational safety. Using a multilevel, multisource, and time-lagged research design, the present study investigates whether safety knowledge affects safety behaviours through safety attitudes and further tests whether supervisory safety attitudes can impact the strength of these relationships and play a role as moderators of the proposed mediated relationship. Data were collected from workers (N = 177) and supervisors (N = 42) in a construction company in the energy industry at two time points. Results indicate full support for the moderated mediation model, demonstrating that worker safety attitudes partially mediate the relationship between safety knowledge and safety behaviours. Moreover, when supervisors had positive attitudes towards safety, both the direct relationship between worker safety attitudes and safety behaviours and the indirect relationship between safety knowledge and safety behaviours were more positive compared to when supervisors had negative safety attitudes. Theoretical and practical implications for occupational safety are discussed.     

Standard and Short RoM Isokinetic Testing: Comparative Analysis in Identifying Submaximal Shoulder External Rotator Effort

An isokinetic-related parameter termed the difference between eccentric-concentric strength ratios at two distinct test velocities (DEC) based on 60° (standard) range of motion (RoM) has been proven to be highly efficient detecting feigned muscular efforts. This study aimed to verify whether a DEC derived from a much shorter test RoM (20°) was equally useful than a long RoM–derived one. Eighteen healthy men (32.4 ± 6.4 years old) took part in a study focusing on shoulder external rotation isokinetic strength. Participants performed a genuine shoulder external rotator maximal effort (eight pairs of concentric and eccentric contractions at high and low velocities at short and long RoM) and then instructed to feign maximal effort. Contraction velocities were adjusted accordingly by applying a 1:4 gradient and peak moments registered. Both condition DEC was then calculated by subtracting the eccentric and concentric strength ratios at low velocities from those at high velocities. DEC scores in the feigned effort were significantly higher than maximal effort ones in both conditions in men. It enabled the setting of specific cutoff levels for separating the efforts. Both approaches revealed a coincident sensitivity (78%) whereas short RoM showed an even higher specificity: 88% versus 78%. Thus, the short RoM protocol provides clinically acceptable detection power.     

What Contributes to College Students’ Cheating? A Study of Individual Factors

To better understand the multiple individual factors that contribute to college cheating, we undertook a multivariate analysis of a national sample of 2,503 college students. Our findings indicated that demographic characteristics (e.g., gender, socioeconomic status, and year in college), character qualities (e.g., lack of self-control, others-oriented life purpose), college experience (e.g., academic preparation, extracurricular activities involvement, and working), and student perceptions and attitudes (e.g., attitude toward academic cheating, perception of faculty’s actions against cheating and cheating environment) are all significantly associated with academic cheating.     

Value From Regulatory Fit

Abstract— Where does value come from? I propose a new answer to this classic question. People experience regulatory fit when the manner of their engagement in an activity sustains their goal orientation or interests regarding that activity. When there is fit, people engage more strongly in what they are doing and "feel right" about it. Fit influences the strength of value experiences—how good or how bad one feels about something—independently of the pleasure and pain experiences that are associated with outcomes. It uniquely contributes to people's experience of the value of things. Fit is shown to influence judgments and decision making, attitude and behavior change, and task performance.
