Clustering in the output of behavior

Pigeons exposed to fixed-interval schedules of 3, 5, 15, 40, and 120 minutes all maintained considerable variability in daily response rates for as many as 104 sessions. However, variations did not occur at random. Instead, rate in a session appeared dependent on those occurring previously. The series displayed a wave-like form arising because a group of high rates was followed by a group of low rates and vice versa. These sequential relations produced a curve having irregular periodicity, sometimes superimposed on a declining or rising linear trend. Whether grouping of response rates stemmed from experimental or extra-experimental sources was not determined. If the phenomenon was either totally or partially produced by the schedule itself, it suggests that response rate is determined by a combination of positive and negative feedback. Control by factors extrinisic to the experiment itself implies that response rate may be influenced by some rhythmic physiological process.     

Effects of immediate performance feedback on implementation of behavior support plans

Research has focused on increasing the treatment integrity of school-based interventions by utilizing performance feedback. The purpose of this study was to extend this literature by increasing special education teachers' treatment integrity for implementing antecedent and consequence procedures in an ongoing behavior support plan. A multiple baseline across teacher-student dyads (for two classrooms) design was used to evaluate the effects of performance feedback on the percentage of antecedent and consequence components implemented correctly during 1-hr observation sessions. Performance feedback was provided every other week for 8 to 22 weeks after a stable or decreasing trend in the percentage of antecedent or consequence components implemented correctly. Results suggested that performance feedback increased the treatment integrity of antecedent components for 4 of 5 teachers and consequence components for all 5 teachers. These results were maintained following feedback for all teachers across antecedent and consequence components. Teachers rated performance feedback favorably with respect to the purpose, procedures, and outcome, as indicated by a social validity rating measure.     

Incremental Validity of Locus of Control After Controlling for Cognitive Ability and Conscientiousness

This research examined the criterion-related validity of work-specific locus of control in predicting job performance, including incremental validity after controlling for cognitive ability and conscientiousness. Data from a student sample and from a large employee sample were used to evaluate the scale properties of measures of locus of control, conscientiousness, and cognitive ability. Two concurrent criterion-related validation studies were then conducted to evaluate the incremental validity of locus of control. In both validation studies, locus of control demonstrated overall and incremental relationships with performance after controlling for ability and conscientiousness, such that employees with higher internal locus of control performed more effectively than externals.     

Number-word sequence skill and arithmetic performance

In two studies, the role of the number‐word sequence skill for arithmetic performance was investigated. In the first, children between 4 and 8 years of age were asked to count forward and backward on the number‐word sequence and to solve arithmetic problems followed by post‐solution interviews about solution procedures. The results demonstrated that the number‐word sequence skill predicted both number of problems solved and strategy to solve the problems. In Study 2 it was found that solving doubles (e.g., 2 + 2 = ?) problems served as a link between the number‐word sequence skill and the number of arithmetic problems solved. The findings suggest that counting on the number‐word sequence may be an early solution procedure and that, with increasing counting skill, the child may detect regularities in the number‐word sequence that can be used to form new and more accurate strategies for solving arithmetic problems.     

中学生学习主观幸福感及其影响因素的初步研究

以910名从初一到高三的中学生为被试,采用自编的《中学生学习主观幸福感量表》进行研究。结果表明:(1)中学生学习主观幸福感普遍偏低,且存在学校类型、年级的差异,非重点学校学生学习主观幸福感更低;高二、初二学生学习主观幸福感最低。(2)影响中学生学习主观幸福感的直接因素是学习体验和现有学习成绩,其中,前者作用更大。(3)影响中学生学习主观幸福感的间接因素是社会压力和希望学习成绩,它们通过学习体验或现有学习成绩间接作用于学习主观幸福感。     

A Preliminary Investigation of the Relationship Between Fluency and Application for Multiplication

Research suggests component skill performance has a strong positive relationship with composite skill performance. This study examined the association between accuracy and fluency for the component-composite relationship within multiplication. One hundred and fifty-seven fifth-graders did one-minute assessments for single-digit, and multi-digit multiplication problems. The results demonstrated the students achieved high levels of accuracy but low levels of fluency. Strong correlations between the component-composite skill fluency suggest that fluent component skills may have a significant role in composite skill performance. Moderate/low correlations between component and composite skill accuracy indicate that more than one skill component may contribute to composite skill acquisition.     

“The interviewer is a machine!” Investigating the effects of conventional and technology-mediated interview methods on interviewee reactions and behavior

Despite the growing number of organizations interested in the use of asynchronous video interviews (AVIs), little is known about its impact on interviewee reactions and behavior. We randomly assigned participants (N = 299) from two different countries (Switzerland and India) to a face-to-face interview, an avatar-based video interview (with an avatar as a virtual recruiter), or a text-based video interview (with written questions) and collected data on a set of self-rated and observer-rated criteria. Overall, we found that whereas participants reported more negative reactions towards the two asynchronous interviews, observer ratings revealed similar performance across the three interviews and lower stress levels in the two AVIs. These findings suggest that despite technology-mediated interview methods still not being well-accepted, interviewees are not at a disadvantage when these methods are used in terms of how well interviewees perform and how stressed they appear to external observers. Implications are discussed.     

The adjustment of social trust and Internet use on cognitive bias in social status: Perspective of performance perception

People in different social statuses have different perceptions due to differences in cognition. Combined with the characteristics of public behaviour and cognition, this study examined the impact of the widespread cognitive biases in social status on performance perception. This study used the ordinary least squares model to verify that the cognitive bias in social status has a significant positive impact on the perception of social governance performance. At the same time, a moderated mediation model was constructed to verify that social trust plays a partial mediating role in the influence mechanism of cognitive bias in social status on the perception of social governance performance. The use of the Internet significantly inhibited the influence of cognitive bias in social status on the perception of social governance performance. Although it also weakened the influence of cognitive bias in social status on social trust, the moderating effect on the mediating effect is not obvious. This study verifies and analyses the internal relationship and mechanism of social status cognition deviation and perception of social governance performance from multidisciplinary dimensions, which enriches the social cognition theory of social status, and expands the research on the perception of social governance performance.     

Does learning a skill with the expectation of teaching it impair the skill’s execution under psychological pressure if the skill is learned with analogy instructions?

ObjectiveHaving learners practice a motor skill with the expectation of teaching it (versus an expectation of being tested on it) has been revealed to enhance skill learning. However, this improvement in skill performance is lost when the skill must be performed under psychological pressure due to ‘choking under pressure.’ The present study investigated whether this choking effect is caused by an accrual of declarative knowledge during skill practice and could be prevented if a technique (analogy instructions) to minimize the accrual of declarative knowledge during practice is employed.DesignWe used a 2 (Expectation: teach/test) x 2 (Instructions: analogy/explicit) x 2 (Posttest: low-pressure/high-pressure) mixed-factor design, with repeated measures on the last factor.MethodsOne-hundred fifty-six participants were quasi-randomly assigned (based on sex) to one of four groups. Participants in the teach/analogy and teach/explicit groups practiced golf putting with the expectation of teaching putting to another participant, and analogy instructions or explicit instructions, respectively. Participants in the test/analogy and test/explicit groups practiced golf putting with the expectation of being tested on their putting, and analogy instructions or explicit instructions, respectively. The next day all participants completed low- and high-pressure putting posttests, with their putting accuracy serving as the dependent variable.ResultsWe observed an Expectation x Instructions × Posttest interaction, such that a main effect of expectation was found in the low-pressure posttest, with the teach group exhibiting superior accuracy, and an Expectation × Instructions interaction was revealed for the high-pressure posttest. This interaction resulted from the teach group showing greater accuracy than the test group exclusively when receiving analogy instructions.ConclusionResults show that participants who practiced with the expectation of teaching exhibited superior learning and indicate that they choked under pressure likely due to their accrual of declarative knowledge during practice, since the choking effect was prevented by having them practice with analogy instructions. Accordingly, having learners practice with the expectation of teaching and techniques that minimize the accrual of declarative knowledge is recommended.     

Predictors and outcomes of sports coaches’ athlete-invested contingent self-worth

Some sports coaches not only invest considerable time and energy in their athletes, but also attach their self-worth to the successes and failures of their athletes. Grounded in Self-Determination Theory, the present study aimed to examine the theoretical predictors and outcomes of such Athlete-Invested Contingent Self-worth (AICS). Results from a cross-sectional study (Study 1; N = 740, M_age = 34.37 years) and an experimental vignette-based study among youth sports coaches (Study 2; N = 318, M_age = 38.94 years) indicated that AICS was positively related to a controlling coaching style and negatively related to a structuring style. Study 1 showed that a perceived evaluative club board was positively related to AICS, and Study 2 further demonstrated that poor performance was negatively associated with AICS and that an evaluative climate was related to AICS through experiences of need frustration. The discussion focuses on the pitfalls of coaches’ contingent self-worth for the development of their athletes.
