Cognitive demands of error processing associated with preparation and execution of a motor skill

Maxwell et al. [Maxwell, J. P., Masters, R. S. W., Kerr, E., & Weedon, E. (2001). The implicit benefit of learning without errors. The Quarterly Journal of Experimental Psychology, 54A, 1049–1068. The implicit benefit of learning without errors. The Quarterly Journal of Experimental Psychology, 54A, 1049–1068] suggested that, following unsuccessful movements, the learner forms hypotheses about the probable causes of the error and the required movement adjustments necessary for its elimination. Hypothesis testing is an explicit process that places demands on cognitive resources. Demands on cognitive resources can be identified by measuring probe reaction times (PRT) and movement times. Lengthened PRT and movement times reflects increased cognitive demands. Thus, PRT and movement times should be longer following errors, relative to successful, movements. This hypothesis was tested using a motor skill (golf putting). Furthermore, the association between error processing and the preparation and execution phases of movement was examined. The data confirmed that cognitive demand is greater for trials following an error, relative to trials without an error. This effect was apparent throughout learning and in both the preparatory and execution phases of the movement. Cognitive effort also appeared to be higher during movement preparation, relative to movement execution.     

The effects of relaxation instructions on drinking behavior in the presence of stress.

Previous research indicates that antecedent stress is associated with increased alcohol consumption. The present study examined the influence of different treatments following threatened exposure to a public speaking situation on both drinking style measures and amount consumed in an ad lib drinking assessment session. The treatments included relaxation instructions, a sensitization or stress-enhancing treatment, and an attention-refocusing or neutral control. Significant differences in poststress drinking rates and amount consumed between the stress-relaxation and stress-sensitization groups were found. The data indicate that relaxation is an effective procedure for attenuating the impact of stress on quantity and style of drinking.     

Peers,Social Control,or Guilt? Self-Conscious Emotions as Explanation for Antisocial Behavior

Criminologists rarely include self-conscious emotions like guilt or shame to explain delinquency. Instead, factors external to the individual are often used, such as social institutions, the family, or peers. This study uses a longitudinal sample of 526 youth from two waves of survey data to assess the effects of peer influences, social control, and the self-conscious emotion of guilt on youth problem behaviors. Problem behavior is measured using teacher assessments at Time2. All other variables are baseline youth self-report measures that were collected at Time1. The results show that guilt statistically predicted teacher-assessed problem behaviors. Further work is needed to develop this measure in criminology.     

Once a Utilitarian,Consistently a Utilitarian? Examining Principledness in Moral Judgment via the Robustness of Individual Differences

Although individual differences in the application of moral principles, such as utilitarianism, have been documented, so too have powerful context effects—effects that raise doubts about the durability of people's moral principles. In this article, we examine the robustness of individual differences in moral judgment by examining them across time and across different decision contexts. In Study 1, consistency in utilitarian judgment of 122 adult participants was examined over two different survey sessions. In Studies 2A and 2B, large samples (Ns = 130 and 327, respectively) of adult participants made a series of 32 moral judgments across eight different contexts that are known to affect utilitarian endorsement. Contrary to some contemporary theorizing, our results reveal a strong degree of consistency in moral judgment. Across time and experimental manipulations of context, individuals maintained their relative standing on utilitarianism, and aggregated moral decisions reached levels of near‐perfect consistency. Results support the view that on at least one dimension (utilitarianism), people's moral judgments are robustly consistent, with context effects tailoring the application of principles to the particulars of any given moral judgment.
