Competitive personality attitudes and forgiveness of others

The authors conducted a survey to determine whether competitive attitudes are differentially associated with forgiveness or lack of forgiveness of others. The results showed that hypercompetitiveness was associated with a lack of forgiveness, whereas personal development competitiveness was associated positively with forgiveness. Discussion centers on the need to discourage socialization practices that foster the adoption of a self-contained individualism that is associated with a maladaptive hypercompetitiveness. Instead, parents should promote an ensembled individualism that is associated with a psychologically healthy personal development competitive orientation.     

Compliance and Problem-Solving Competence in Girls and Boys

The problem-solving abilities of 4- and 5-year old children (N = 208) were assessed to test the hypothesis that high levels of compliance are negatively related to problem solving. Problem-solving competence was examined with a task-specific measure and a standardized measure of general problem-solving performance. Low compliant children performed better on both measures. The role of compliance in the cognitive development of girls and boys is discussed.     

Non-LIFO Execution of Cognitive Procedures

Many current theories of human problem solving and skill acquisition assume that people work only on the unsatisfied goal that was created most recently. That is, the architecture obeys a last-in-first-out (LIFO) constraint on the selection of goals. This restriction seems necessary for the proper functioning of automatic learning mechanisms, such as production compilation and chunking. It is argued that this restriction is violated by some subjects on some tasks. In particular, 8 subjects (from a sample of 26) execute subtraction procedures in a way that violates the LIFO constraint. Although there is a great deal of between- and within-subject strategy variation in the 8 subjects' behavior, it can be simply explained by hypothesizing that (1) the goal selection is not necessarily LIFO, (2) goal selection knowledge is represented by explicit preferences, and (3) the 8 subjects have just a few preferences that are overgeneralized, overspecialized, or missing. The rest of their preferences are correct. On the other hand, LIFO-based models seem unable to explain the strategy variations in any simple way. Thus, it seems that part of the flexibility in human problem solving comes from having a choice of which goal to work on next. Fortunately, it is simple to ammend automatic learning mechanisms so that they will function correctly in a non-LIFO architecture.     

Increased attention for computer-tailored health communications: an event-related potential study.

The authors tested whether individually tailored health communications receive more attention from the reader than nontailored health communications in a randomized, controlled trial among student volunteers (N = 24). They used objective measures of attention allocation during the message exposure. In a between-subjects design, participants had to read tailored or nontailored nutrition education messages and at the same time had to pay attention to specific odd auditory stimuli in a sequence of frequent auditory stimuli (odd ball paradigm). The amount of attention allocation was measured by recording event-related potentials (ERPs; i.e., N100 and P300 ERPs) and reaction times. For the tailored as opposed to the nontailored group, results revealed larger amplitudes for the N100 effect, smaller amplitudes for the P300 effect, and slower reaction times. Resource allocation theory and these results suggest that those in the tailored group allocated more attention resources to the nutrition message than those in the nontailored group.     

Without Thinking: Impulsive Aggression and Criminal Responsibility

In the U.S. the decision to impose criminal responsibility rests on an assumption about the defendant's decision to engage in proscribed conduct. We punish only those who we believe had the capacity to make a choice. In an increasingly violent world, the criminal law and the assumptions upon which it rests are relentlessly tested. A new generation of neuro-imaging technologies offers to provide insights into structural and functional abnormalities in the brain that may limit the autonomy of many dangerous offenders and unravel the fabric of the criminal justice system. How will the results of these technologies be received by the courts—are they relevant to existing formulations of the prima facie case, the insanity defense, or mitigation of sentence; will changes in the science or the law be required to accommodate this knowledge? The new generation of technologies may appropriately play a role in assessing culpable mental states only if they are also reliable. This short article takes on these and a host of other related questions at the intersection between science, law, and science fiction. Copyright © 2008 John Wiley & Sons, Ltd.
