An Empirical Study of Future Professionals’ Intentions to Engage in Unethical Business Practices

This paper sought to test whether student demographics (gender, age, religion, type of degree and number of courses done containing ethics) influenced the likelihood of engaging in unethical business practices. The study involved the use of a questionnaire being administered to a sample of 231 undergraduate students in Barbados. It was found that gender, religiousness, type of degree and number of courses taken containing ethics significantly impacted on the intentions to engage in unethical behaviour. It was also found that the impact of age was not conclusive. The study has several limitations including low generalisability due to the use of a non-probability sampling method, and the possibility of social desirability bias. The study informs educators about the need to integrate ethics into the curriculum as an essential component of professional training for future managers and business people. This study makes an important contribution to the ethics literature on small island developing states, since the study was done in the country of Barbados.     

Localizing practice effects in dual-task performance

Practice effects on dual-task processing are of interest in current research because they may reveal the scope and limits of parallel task processing. Here we used onsets of the lateralized readiness potential (LRP), a time marker for the termination of response selection, to assess processing changes after five consecutive dual-task sessions with three stimulus onset asynchronies (SOAs) and priority on Task 1. Practice reduced reaction times in both tasks and the interference between tasks. As indicated by the LRP, the reduction of dual-task costs can be explained most parsimoniously by a shortening of the temporal demands of central bottleneck stages, without assuming parallel processing. However, the LRP also revealed a hitherto unreported early activation over the parietal scalp after practice in the short SOA condition, possibly indicating the isolation of stimulus-response translation from other central processing stages. In addition, further evidence was obtained from the LRP for a late motoric bottleneck, which is robust against practice.     

Dispositional Hardiness And Women'S Well-Being Relating To Gender Discrimination: The Role Of Minimization

Three studies examined whether personality-based hardiness would be associated with mental health benefits in contexts of gender discrimination. Hardy women encountering both a laboratory simulation and a hypothetical scenario of discrimination showed greater self-esteem and less negative affect than low hardy women. However, these benefits were mediated by the use of specific attributions, suggesting that well-being in hardy women may have been achieved through minimizing the pervasiveness of discrimination. The third study showed this mediation pattern occurred only for participants exposed to higher threat scenarios versus lower threat scenarios of discrimination. Thus, minimizing the pervasiveness of discrimination may have been a threat-reducing tool for high hardy women. Bandura's (1997) self-efficacy theory was used as a possible explanation for this finding.     

Synaptogenesis and heritable aspects of executive attention

In humans, changes in brain structure and function can be measured non-invasively during postnatal development. In animals, advanced optical imaging measures can track the formation of synapses during learning and behavior. With the recent progress in these technologies, it is appropriate to begin to assess how the physiological processes of synapse, circuit, and neural network formation relate to the process of cognitive development. Of particular interest is the development of executive function, which develops more gradually in humans. One approach that has shown promise is molecular genetics. The completion of the human genome project and the human genome diversity project make it straightforward to ask whether variation in a particular gene correlates with variation in behavior, brain structure, brain activity, or all of the above. Strategies that unify the wealth of biochemical knowledge pertaining to synapse formation with the functional measures of brain structure and activity may lead to new insights in developmental cognitive psychology.     

Hemispheric dominance in schizophrenics as determined on extrapyramidal side effects of neuroleptics

Phenomena observed during treatment with neuroleptics were clinically measured in an attempt to determine the difference in vulnerability of the two hemispheres and the relation between this difference and schizophrenic diseases. In the group of systematic schizophrenias the increase in tonus was significantly higher in the dominant hemisphere. This finding is considered a verification of the nosological hypothesis of schizophrenias.     

Self-Efficacy and Causal Attributions: Direct and Reciprocal Links

This study examines Bandura's (1986, 1997a) propositions that self-efficacy provides information from which causal attributions are made and that causal attributions, in turn, influence formation of subsequent self-efficacy expectations. We developed a conceptual rationale for and empirically tested 2 sets of hypotheses pertaining to direct and reciprocal links between self-efficacy and causal attributions. Effects of causal attributions and subsequently formed self-efficacy on subsequent task performance were also investigated. Results support the existence of direct and reciprocal links between self-efficacy and causal attributions. We found interactive effects between self-efficacy and performance feedback on causal attributions, and a mediating effect of causal attributions on the formation of subsequent self-efficacy beliefs. Causal attributions and subsequent self-efficacy also significantly predicted subsequent performance.
