When to Self-Correct?: A Comparison of Two Procedures on Spelling Performance

We compared the effects of two self-correction procedures on the spelling performance of 5 elementary school students with learning disabilities. Previous studies consistently have demonstrated self-correction to be more effective than traditional approaches to spelling instruction. However, we could find no single-subject design experiments analyzing the procedural details of how or when self-correction should be conducted to be most effective. For 4 days each week students practiced a list of 20 spelling words by listening to an audiotape on which the weekly list was dictated and writing the words. For half of each week's words, students checked and self-corrected after attempting each word; for the other half of the list, the students self-corrected after attempting all 10 words. An alternating treatments design showed self-correction after each word to be more effective for acquisition of new spelling words as measured by end-of-the-week tests for all 5 students, and maintenance of previously studied spelling words as measured by 1-week maintenance tests for 4 of the 5 students.     

Structural Stability within the Lateral Cerebellar Nucleus of the Rat Following Complex Motor Learning

Complex motor learning, but not mere motor activity, has been previously shown to induce structural modifications within the cerebellar cortex. The present experiment examined whether similar changes occur within one of the primary output targets of the region of the cerebellar cortex in which these structural changes were described, the lateral cerebellar nucleus (LCN; dentate nucleus). Adult female rats were randomly allocated to one of three training conditions. Acrobatic condition (AC) rats were trained to complete a complex motor learning task consisting of a series of elevated obstacles while motor control (MC) condition animals were forced to traverse a flat obstacle-free runway equal in length to the AC task. Inactive condition (IC) animals received no motor training. Unbiased stereological techniques and electron microscopy were used to obtain estimates of synapse number and postsynaptic density (PSD) length within the LCN. Results showed that neither synapse number nor PSD length was significantly altered as a function of training condition. These results indicate that complex motor skill learning is associated with structural plasticity within the cerebellar cortex and with structural stability within the lateral cerebellar nucleus.     

成就目标对青少年成就动机和学业成就影响的研究

本研究在迈尔（Maehr）等人研究的基础上,考察了成就目标（任务目标和能力目标）与动机和学业成就之间的关系。结果表明,任务目标通过内部动机对学业成就产生积极的影响,能力目标通过外部动机对学业成就产生消极的影响。     

The Role of Trait Emotional Intelligence in Academic Performance: Theoretical Overview and Empirical Update

Considerable debate still exists among scholars over the role of trait emotional intelligence (TEI) in academic performance. The dominant theoretical position is that TEI should be orthogonal or only weakly related to achievement; yet, there are strong theoretical reasons to believe that TEI plays a key role in performance. The purpose of the current article is to provide (a) an overview of the possible theoretical mechanisms linking TEI with achievement and (b) an update on empirical research examining this relationship. To elucidate these theoretical mechanisms, the overview draws on multiple theories of emotion and regulation, including TEI theory, social-functional accounts of emotion, and expectancy-value and psychobiological model of emotion and regulation. Although these theoretical accounts variously emphasize different variables as focal constructs, when taken together, they provide a comprehensive picture of the possible mechanisms linking TEI with achievement. In this regard, the article redresses the problem of vaguely specified theoretical links currently hampering progress in the field. The article closes with a consideration of directions for future research.     

A crowdsourced nickel‐and‐dime approach to analog OBM research: A behavioral economic framework for understanding workforce attrition

Incentives are a popular method to achieve desired employee performance; however, research on optimal incentive magnitude is lacking. Behavioral economic demand curves model persistence of responding in the face of increasing cost and may be suitable to examine the reinforcing value of incentives on work performance. The present use‐inspired basic study integrated an experiential human operant task within a crowdsourcing platform to evaluate the applicability of behavioral economics for quantifying changes in workforce attrition. Participants included 88 Amazon Mechanical Turk Workers who earned either a $0.05 or $0.10 incentive for completing a progressively increasing response requirement. Analyses revealed statistically significant differences in breakpoint between the two groups. Additionally, a novel translation of the Kaplan‐Meier survival‐curve analyses for use within a demand curve framework allowed for examination of elasticity of workforce attrition. Results indicate greater inelastic attrition in the $0.05 group. We discuss the benefits of a behavioral economic approach to modeling employee behavior, how the metrics obtained from the elasticity of workforce attrition analyses (e.g., P _max) may be used to set goals for employee behavior while balancing organizational costs, and how economy type may have influenced observed outcomes.     

Le momentum psychologique en sport : vers une perspective complexe et dynamique

Psychological momentum (PM) is a social phenomenon that has triggered the curiosity of sport psychologists since the early 1980s. From early to recent conceptualizations, PM has been considered as a complex construct, inherently related to variations in sport performance. Over the past 30 years, several models have been proposed to untangle how PM is triggered, which psychological changes are involved in PM experiences, and how PM relates to performance. While linear (causal) models have dominated past research on PM, researchers have recently found that PM can change nonlinearly, depending on the performance history of the competition. This systematic review aims to provide an overview of different PM models that have been proposed in the past to increase insights into the complexity of PM, including the transition from linear causal models to nonlinear dynamical models. Moreover, based on the current state of affairs, perspectives for future research are provided.     

The two roads of passionate goal pursuit: links with appraisal,coping, and academic achievement

Background and Objectives: In this research, we tested the role of cognitive appraisals in explaining why harmonious and obsessive passion dimensions are related to distinct forms of coping and explored if performance was impacted by these appraisal and coping processes. Design: Undergraduate students (N = 489) participated in a longitudinal study and completed three surveys throughout the course of an academic year. Methods: Participants completed assessments of both passion dimensions (Time 1), reported how they were appraising and coping with the mid-year examination period (Time 2), and provided consent to obtain their final grade in Introductory Psychology (Time 3). The hypothesized model was tested using structural equation modeling. Results: Harmonious and obsessive passion dimensions were linked with approach and avoidant coping responses, respectively. Cognitive appraisals, particularly appraisals of challenge and uncontrollability, played an indirect role in these relationships. In addition, both appraisals and coping responses had an indirect effect in the relationship between passion dimensions and final grade. Conclusions: These results identify cognitive appraisal as a reason why passion dimensions are linked with distinct coping tendencies and demonstrate the role of appraisal and coping processes in the journey to passionate goal attainment.
