Introducing uninteresting tasks to children: a comparison of the effects of rewards and autonomy support

Two experiments compared rewards and autonomy support as methods to promote children's self-regulation for an uninteresting vigilance task. Dependent measures were ratings of positive affect, perception of the task's value, and free-choice engagement. ANOVA results revealed some positive effects associated with autonomy support, whereas no effect for rewards was found in either study. The outcomes of most interest were correlations between free-choice behavior and self-reported measures of affect and value, reflecting the level of integration in self-regulation. As predicted by self-determination theory (Deci & Ryan, 1985, 1991, 2000), rewards were associated with behaviors incongruent from affect and value, whereas autonomy support led to integrated self-regulation. This finding was first detected in Study 1 and later replicated in Study 2. Together, these results point to autonomy support as a beneficial alternative to the common use of rewards.     

A longitudinal study of the relationship of maternal autonomy support to children's adjustment and achievement in school

A longitudinal study examined the relations of maternal autonomy support to children's school adjustment. Autonomy support and other parenting dimensions were measured when children were 5 years old. School measures were teacher-rated academic and social adjustment and achievement in reading and math in grade 3. Regression analyses controlling for age 5 family and child factors (e.g., socioeconomic status [SES], kindergarten adjustment, IQ) revealed that autonomy support was positively related to grade 3 adjustment (social and academic) and reading achievement. Maternal emphasis on school performance was positively related to achievement measures but negatively related to social adjustment. Maternal use of rewards and praise was unrelated to grade 3 school measures. Finally, supplemental analyses revealed that autonomy support was associated with greater consistency in children's adjustment across social and academic domains as well as higher overall adjustment. These results highlight the developmental significance of parental autonomy support in early childhood.     

More on the fragility of performance: choking under pressure in mathematical problem solving

In 3 experiments, the authors examined mathematical problem solving performance under pressure. In Experiment 1, pressure harmed performance on only unpracticed problems with heavy working memory demands. In Experiment 2, such high-demand problems were practiced until their answers were directly retrieved from memory. This eliminated choking under pressure. Experiment 3 dissociated practice on particular problems from practice on the solution algorithm by imposing a high-pressure test on problems practiced 1, 2, or 50 times each. Infrequently practiced high-demand problems were still performed poorly under pressure, whereas problems practiced 50 times each were not. These findings support distraction theories of choking in math, which contrasts with considerable evidence for explicit monitoring theories of choking in sensorimotor skills. This contrast suggests a skill taxonomy based on real-time control structures.     

A multilevel analysis of the interpersonal behavior of socially anxious people

We investigate the interpersonal behavior of socially anxious (SA) and non-socially anxious (NSA) individuals at three different levels of analysis, focusing on the dimensions of warmth and dominance. Study 1 examines self-reported general interaction styles, Study 2 explores behavior occurring within the context of a single interaction, and in Study 3 we focus on the performance of a single conversational act (a disagreement). Studies 1 and 2 adopt the framework of Interpersonal Circumplex Theory (IPC; Kiesler, 1983), which is well suited for studying trait-level and interaction-level social behaviors, while Study 3 is grounded in Politeness Theory (PT; Brown & Levinson, 1987), which can be used to analyze individual acts at the microstructural level. The potential mutual relevance of PT and IPC is also discussed.     

Can the Transition To and From Running and the Metabolic Cost of Running Be Determined From the Kinetic Energy of Running?

An experiment was conducted in which volume of used oxygen per stride time and the total segmental changes in kinetic energy generated per stride time, &grD;E(k)>s(-1), of 11 participants were determined on Day 1 for 7 treadmill running speeds. Gait transition speeds were determined on Day 2. Running metabolism and transition speed were predicted from the Day 1 mechanics of running expressed in Speed x &grD;E(k)>s(-1) coordinates. Predictions followed from the relation between 2 generalized quality ratios Q(metab), and Q(mech), with numerator &grD;E(k)>s(-1). In Q(metab), the denominator was the volume of used oxygen per stride time; in Q(mech), the denominator was the absolute regression constant from the linear dependency of &grD;E(k)>s(-1) on speed.     

The effects of token reinforcement,feedback and response cost on standardized test performance

The primary purpose of the present study was to compare the differential effects of token reinforcement, feedback, and response cost on the test performance of delinquent boys. Eighty students were randomly assigned to three experimental groups and one control group of 20 subjects each. Each experimental group received a standard and a modified administration of the verbal section of the WISC. For the token reinforcement group, the modified WISC administration permitted students to earn tokens contingent on correct responses; the response cost group forfeited tokens contingent on incorrect responses; and the feedback group simply received information regarding the accuracy of each response. The control group received two standard WISC administrations. The primary measure was the difference in verbal I.Q. scores between the standard and modified WISC administrations. Results indicated that the token reinforcement and response cost groups achieved significantly higher scores than the feedback and control groups. No significant differences were found between the token reinforcement and response cost groups nor between the feedback and control groups. The implications of these findings for clarifying the relationship between motivational condition and test performance are discussed.
