Children's Responses to Entry Failure: Attention Deployment Patterns and Self-Regulation Skills

In this study the authors investigated associations among children's observed responses to failure in an analogue entry situation, their attention deployment patterns, and skills and processes associated with self-regulation. Participants were 54 kindergarten and first-grade students who were either aggressive-rejected or low aggressive-popular based on peer nominations. Inhibitory control predicted the tendency to respond to entry failure by stopping and watching the group's activity. Baseline vagal tone and other-directed attention predicted children's tendency to change entry strategies after failure. Parent-rated attention skills moderated the relation between children's attention deployment patterns during the entry task and their responses to entry failure. Children who engaged in more other-directed attention were less likely to turn to solitary play after entry failure but only if they had high or moderate levels of attentional control. Other-directed attention was related to repeating previous entry bids without modification after entry failure but only when children had high levels of attention problems.     

Interplay of Biomechanical Constraints and Kinematic Strategies in Selecting Arm Postures

In this study, the authors examined the interplay between biomechanics and control strategies in the resolution of excess degrees of freedom at the joint level. Seven participants made aimed arm movements from 30 starting points and several starting postures to targets. Final arm postures for movements to a target exhibited substantial joint angle variation. Through regression modeling and by comparing observed final arm postures with biomechanically plausible postures, the authors identified 3 kinematic strategies: (a) Maintain deviations from the average angle at the starting point to the joint's final posture; (b) make torso rotations that are a fixed proportion of shoulder rotations; and (c) adopt a characteristic combination of 4 wrist-positioning approaches. The results demonstrated that kinematic strategies can account for substantial variance in final arm postures, if one takes into account 2 types of individual differences—those that arise inevitably from biomechanical constraints and those that reflect choices in movement strategy.     

The Semantics of Secrecy: Young Children's Classification of Secret Content

The authors explored whether young children can distinguish potential secrets from nonsecrets by their content, as can older children, adolescents, and adults. Ninety children, 4, 5, and 6 years old, rated the secrecy of items from an adult-validated list of personal information about an age- and gender-appropriate puppet. Two factors of the children's data corresponded to the adult categories of nonsecrets and secrets, and a third factor corresponded to surprises. All ages rated surprises as significantly more secret than nonsecret items; however, the surprise items contained linguistic cues to secrecy. A tendency to rate nonsecrets as secret decreased with age, but only the 6-year-olds rated secrets other than surprises as significantly more secret than nonsecrets. Thus, children acquire the implicit rules defining secret content from a somewhat later age than that reported for the cognitive or behavioral capacities for secrecy.     

Physical and Observational Practice Afford Unique Learning Opportunities

In 2 experiments, the authors studied the effectiveness of physical and observational practice on learning and the effect on learning of combining physical practice and observation, as compared with providing physical practice alone. In Experiment 1, retention and transfer performance of 30 university students after physical, observational, or no practice were contrasted. Consistent with findings from other studies, the retention results indicated that observational practice is inferior to physical practice. The transfer data indicated no differences between observation and physical practice groups. In Experiment 2, retention and transfer performance of 30 participants in physical and combined (alternating physical and observational) practice groups were contrasted. The retention results showed no differences between the combined and physical practice groups, but the combined group performed significantly better than the physical practice group on the transfer test. Those findings suggest that a combination of observation and physical practice permits unique opportunities for learning beyond those available via either practice regimen alone.     

Offline Improvement during Motor Sequence Learning Is Not Restricted to Developing Motor Chunks

Robust offline performance gains, beyond those that would be anticipated by being exposed to additional physical practice, have been reported during procedural learning and have been attributed to enhancement consolidation, a process by which memory is transformed in such a way that it is not only more resistant to forgetting but may also involve a reorganization of information that supports superior task execution. The authors assessed the impact of increasing within-session practice extent on the emergence of offline performance gains. Practice-dependent improvements occurred across 12 and 24 30-s practice trials of a 5-element motor sequencing task. Offline improvements were observed following both 12 and 24 trials. The improvement following 12 trials was associated with the formation of motor chunks important for establishing movement sequence structure. In contrast, the offline improvement after 24 trials was not related to further changes in movement structure beyond those that had emerged during practice. These data suggest that additional memory operations, beyond those needed to amalgamate subsequences of the SRT task, are susceptible to enhancement consolidation.     

"i hope someone murders your mother!": an exploration of extreme support for the death penalty

Although general support for the death penalty is decreasing, a segment of the pro-death penalty population continues to support capital punishment with great vehemence. Extreme support for the death penalty is expressed through angry, confrontational, and sometimes threatening verbal attacks against condemned prisoners and opponents of capital punishment. Expressions of this support are especially strong around the time of highly publicized executions. This paper explores extreme support for capital punishment in the months before and after Tennessee's first execution in 40 years, using data gathered from newspaper reports, letters to the editor, interviews with death penalty opponents, and the authors' own experiences. Linking Bowers and Pierce's brutalization theory with community psychology theory, we explore ways in which highly publicized executions seem to unleash of hatred and violent intention among a number of death penalty supporters and how this behavior may illuminate research of increases in homicide after highly executions.     

No evidence of racial discrimination in criminal justice processing: Results from the National Longitudinal Study of Adolescent Health

One of the most consistent findings in the criminological literature is that African American males are arrested, convicted, and incarcerated at rates that far exceed those of any other racial or ethnic group. This racial disparity is frequently interpreted as evidence that the criminal justice system is racist and biased against African American males. Much of the existing literature purportedly supporting this interpretation, however, fails to estimate properly specified statistical models that control for a range of individual-level factors. The current study was designed to address this shortcoming by analyzing a sample of African American and White males drawn from the National Longitudinal Study of Adolescent Health (Add Health). Analysis of these data revealed that African American males are significantly more likely to be arrested and incarcerated when compared to White males. This racial disparity, however, was completely accounted for after including covariates for self-reported lifetime violence and IQ. Implications of this study are discussed and avenues for future research are offered.
