Understanding deliberate practice in preschool-aged children

Deliberate practice is essential for skill acquisition and expertise and may be a direct consequence of episodic foresight. However, little is known about how deliberate practice develops in children. We present two experiments testing children's ability to selectively practise a behaviour that was going to be useful in future and to reason about the role of practice in skill formation. Five-year-olds demonstrated an explicit understanding of deliberate practice both in selectively choosing to practise a future-relevant skill and in predicting skill change in others based on their practice. Four-year-olds showed some capacities, but failed to demonstrate consistent understanding of the relationship between practice and skill improvement. Children's understanding of this relationship was significantly related to their understanding of how information leads to knowledge, suggesting that both may draw on similar cognitive developmental changes.     

The utilization of visual information in the control of reciprocal aiming movements

Two experiments examined on-line processing during the execution of reciprocal aiming movements. In Experiment 1, participants used a stylus to make movements between two targets of equal size. Three vision conditions were used: full vision, vision during flight and vision only on contact with the target. Participants had significantly longer movement times and spent more time in contact with the targets when vision was available only on contact with the target. Additionally, the proportion of time to peak velocity revealed that movement trajectories became more symmetric when vision was not available during flight. The data indicate that participants used vision not only to 'home-in' on the current target, but also to prepare subsequent movements. In Experiment 2, liquid crystal goggles provided a single visual sample every 40 ms of a 500 ms duty cycle. Of interest was how participants timed their reciprocal aiming to take advantage of these brief visual samples. Although across participants no particular portion of the movement trajectory was favored, individual performers did time their movements consistently with the onset and offset of vision. Once again, performance and kinematic data indicated that movement segments were not independent of each other.     

Hoarding in obsessive-compulsive disorder: results from the OCD Collaborative Genetics Study

Hoarding behavior occurs frequently in obsessive-compulsive disorder (OCD). Results from previous studies suggest that individuals with OCD who have hoarding symptoms are clinically different than non-hoarders and may represent a distinct clinical group. In the present study, we compared 235 hoarding to 389 non-hoarding participants, all of whom had OCD, collected in the course of the OCD Collaborative Genetics Study. We found that, compared to non-hoarding individuals, hoarders were more likely to have symmetry obsessions and repeating, counting, and ordering compulsions; poorer insight; more severe illness; difficulty initiating or completing tasks; and indecision. Hoarders had a greater prevalence of social phobia and generalized anxiety disorder. Hoarders also had a greater prevalence of obsessive-compulsive and dependent personality disorders. Five personality traits were independently associated with hoarding: miserliness, preoccupation with details, difficulty making decisions, odd behavior or appearance, and magical thinking. Hoarding and indecision were more prevalent in the relatives of hoarding than of non-hoarding probands. Hoarding in relatives was associated with indecision in probands, independently of proband hoarding status. The findings suggest that hoarding behavior may help differentiate a distinct clinical subgroup of people with OCD and may aggregate in some OCD families. Indecision may be a risk factor for hoarding in these families.     

Managerial motivational profiles: Composition,antecedents, and consequences

Using a person-centered approach, we identified managers' (N = 321) motivational profiles and tested a model of the antecedents and consequences of these profiles. The profiles were based on four motivational types delineated by self-determination theory (i.e., external, introjected, identified, intrinsic). Latent profile analysis revealed six distinct motivational profiles. One of these was a self-determined profile (high identified and intrinsic motivation, moderately low introjected motivation, and low external motivation). Four other profiles combined average levels of external motivation with either very low, low, moderately low, or high internal (i.e., introjected, identified, and intrinsic) motivation. The final profile involved moderately high levels of all four motives. The antecedents of profile membership examined were perceived supervisor support and perceived organizational politics. The career-related outcomes of profile membership were work attitudes and promotability. The self-determined and high internal motivation profiles were associated with the most favorable work attitudes, followed by the moderately high motivation profile. The low internal motivation profiles were associated with the least favorable attitudes. Promotability did not differ across the profiles. With respect to the antecedents, low levels of supervisor support and high levels of politics increased the odds that a manager would exhibit profiles that were less desirable than the self-determined profile. Our findings provide initial information about managers' motivational profiles, as well as the antecedents and consequences of these profiles. Further, these results demonstrate the promise of a person-centered approach for advancing motivation research and management development.     

Status Frustration among College Students: The Relationship between Socioeconomic Status and Undergraduate Performance

Cohen’s status frustration theory explains that even though everyone is encouraged to achieve a high status in society, lower-class people have very small chances of successfully doing so. Students from a private college and a public community college were given questionnaires about socioeconomic statuses, college majors, career plans, grades, and participation in delinquent activities. Findings support specific components of Cohen’s theory. Minority and lower-class students participated in more deviant behaviors. Results also revealed significant differences in prestige of career goals between students of different social classes. Finally, there was a significant relationship between perceived opportunities and grade point averages.     

On interpreting stereotype threat as accounting for African American-White differences on cognitive tests

C. M. Steele and J. Aronson (1995) showed that making race salient when taking a difficult test affected the performance of high-ability African American students, a phenomenon they termed stereotype threat. The authors document that this research is widely misinterpreted in both popular and scholarly publications as showing that eliminating stereotype threat eliminates the African American-White difference in test performance. In fact, scores were statistically adjusted for differences in students' prior SAT performance, and thus, Steele and Aronson's findings actually showed that absent stereotype threat, the two groups differ to the degree that would be expected based on differences in prior SAT scores. The authors caution against interpreting the Steele and Aronson experiment as evidence that stereotype threat is the primary cause of African American-White differences in test performance.     

Using SAT-grade and ability-job performance relationships to test predictions derived from stereotype threat theory

To examine the generalizability of stereotype threat theory findings from laboratory to applied settings, the authors developed models of the pattern of relationships between cognitive test scores and outcome criteria that would be expected if the test scores of women and minority group members were affected by stereotype threat. Two large data sets were used to test these models, one in an education setting examining SAT-grade relationships by race and gender and the other in a military job setting examining Armed Services Vocational Aptitude Battery-job performance relationships by race. Findings were not supportive of the predictions arising from stereotype threat theory, suggesting caution in positing threat as a key determinant of subgroup mean test score differences in applied settings.     

The application of a behavioural regime to disturbed young offenders

A 6-month behavioral project was carried out at HM Borstal Feltham, Middlesex, a custodial institution for young male offenders aged 16–21 serving an indeterminate sentence of between 6 months and 2 years. Twelve trainees with a variety of clinical histories were involved in the project. Operant techniques including a points incentive scheme and individual contracting were structured in an attempt to improve behaviours relevant to discharge as well as borstal adjustment. Results indicate several improvements in terms of borstal offending, and the acquisition of new skills. The effects of applying behavioural techniques systematically to a small unit were consistently favourable. A number of learning points arose related to the problems of staff training, relationships between different grades and the need to work within one clear theoretical model exclusively.
