Why additional presentations help identify a stimulus

Nosofsky (1983) reported that additional stimulus presentations within a trial increase discriminability in absolute identification, suggesting that each presentation creates an independent stimulus representation, but it remains unclear whether exposure duration or the formation of independent representations improves discrimination in such conditions. Experiment 1 replicated Nosofsky's result. Experiments 2 (masking the ISI between two-presentations) and 3 (manipulating stimulus duration without changing number of presentations or overall trial duration) ruled out an explanation in terms of extended opportunities for stimulus sampling, from either a sensory buffer during additional ISIs or increased stimulus exposure, respectively. Experiment 4 (comparing two and three-presentations, other factors controlled) provided some limited additional support for Nosofsky's original claim that additional stimulus presentations can create either independent or duplicate representations. Experiments 5 and 6 (both manipulating ISI) demonstrated that a key factor in the additional stimulus presentation effect is the overall trial duration. We discuss the results in relation to models of absolute identification, their relative emphasis on stimulus sampling versus response selection, and the mechanisms by which duplicate representations could be created.     

Strategic adaptation to performance objectives in a dual-task setting

How do people interleave attention when multitasking? One dominant account is that the completion of a subtask serves as a cue to switch tasks. But what happens if switching solely at subtask boundaries led to poor performance? We report a study in which participants manually dialed a UK‐style telephone number while driving a simulated vehicle. If the driver were to exclusively return his or her attention to driving after completing a subtask (i.e., using the single break in the xxxxx‐xxxxxx representational structure of the number), then we would expect to see a relatively poor driving performance. In contrast, our results show that drivers choose to return attention to steering control before the natural subtask boundary. A computational modeling analysis shows that drivers had to adopt this strategy to meet the required performance objective of maintaining an acceptable lateral position in the road while dialing. Taken together these results support the idea that people can strategically control the allocation of attention in multitask settings to meet specific performance criteria.     

Should Happiness-Maximization be the Goal of Government?

Recent social surveys of happiness (subjective well-being) have given a new stimulus to utilitarian political theory by providing a statistically reliable measure of the ‘happiness’ of individuals that can then be correlated with other variables. One general finding is that greater happiness does not correlate strongly with increased wealth, beyond modest levels, and this has led to calls for governments to shift priorities away from economic growth and towards other social values. This paper notes how the conclusions of this research help to address some of the traditional objections to utilitarianism. The question of how happiness research findings can be used to set happiness-maximization goals for public policy needs careful examination, as the translation from research to policy is not always straightforward. Some empirical and ethical objections to this ‘new utilitarianism’ are raised. The complicating factors of public expectations of, and trust in, governments pose obstacles to any proposal that happiness research may lead to changes in public policy and hence to ‘happier’ populations.     

Computer scoring of the Levels of Emotional Awareness Scale

The Levels of Emotional Awareness Scale (LEAS; Lane, Quinlan, Schwartz, Walker, & Zeitlan, 1990) is the most commonly used measure of differentiation and complexity in the use of emotion words and is associated with important clinical outcomes. Hand scoring the LEAS is time consuming. Existing programs for scoring open-ended responses cannot mimic LEAS hand scoring. Therefore, Leaf and Barchard (2006) developed the Program for Open-Ended Scoring (POES) to score the LEAS. In this article, we report a study in which the reliability and validity of POES scoring were examined. In the study, we used three participant types (adult community members, university students, children), three LEAS versions (paper based, computer based, and the LEAS for children), and a diverse set of criterion variables. Across this variety of conditions, the four POES scoring methods had internal consistencies and validities that were comparable to hand scoring, indicating that POES scoring can be used in clinical practice and other applied settings in which hand scoring is impractical.     

Malingering as a categorical or dimensional construct: the latent structure of feigned psychopathology as measured by the SIRS and MMPI-2

The 6 nonoverlapping primary scales of the Structured Interview of Reported Symptoms (SIRS) were subjected to taxometric analysis in a group of 1,211 criminal and civil examinees in order to investigate the latent structure of feigned psychopathology. Both taxometric procedures used in this study, mean above minus below a cut (MAMBAC) and maximum covariance (MAXCOV), produced dimensional results. A subgroup of participants (n = 711) with valid Minnesota Multiphasic Personality Inventory-2 (MMPI-2) protocols were included in a second round of analyses in which the 6 nonoverlapping primary scales of the SIRS and the Infrequency (F), Infrequency-Psychopathology (Fp), and Dissimulation (Ds) scales of the MMPI-2 served as indicators. Again, the results were more consistent with dimensional latent structure than with taxonic latent structure. On the basis of these findings, it is concluded that feigned psychopathology forms a dimension (levels of fabrication or exaggeration) rather than a taxon (malingering-honest dichotomy) and that malingering is a quantitative distinction rather than a qualitative one. The theoretical and clinical practice implications of these findings are discussed.     

Safeguarding Tradition: Psychological Type Preferences of Male Vergers in the Church of England

The current study explores the psychological type profile of vergers within the Church of England. A sample of 42 male vergers completed the Myers-Briggs Type Indicator (Form G). The study shows that vergers tend to prefer introversion over extraversion, sensing over intuition, thinking over feeling, and judging over perceiving. The type preferences of vergers are compared and contrasted with the type preferences of clergy and laity. These findings are explored within the context of the role of the verger within the Church of England.     

How a supportive partner may increase relationship satisfaction

The way in which satisfaction with a romantic relationship may be affected by how supportive a partner is and how constructively they deal with conflict in that relationship was examined in young adults. Both greater support and less conflict were found to be independently associated with relationship satisfaction, implying that both are necessary for a satisfactory relationship. While support did not mitigate the possible effects of conflict on satisfaction, it may lead to more constructive conflict which in turn may enhance satisfaction. Support seen as being available as well as support that was received were independently associated with relationship satisfaction. Of the different forms of available support measured, only support reflecting being cared for was independently associated with relationship satisfaction. These results suggest that encouraging couples to be emotionally supportive to each other may improve the effectiveness of relationship counselling as well as relationship enhancement and problem prevention programmes.

Modern racism and neo‐liberal globalization: the discourses of plausible deniability and their multiple functions

Recently, considerable energy has been focused on extending the mandate of anti‐racism. Modern (or symbolic) racism and discursive psychology have argued that racism has taken on more covert forms. A longitudinal examination of newspaper coverage of two important race‐related newsprint stories in New Zealand (involving Winston Peters, Tuku Morgan and New Zealand First) identified discourses of ‘plausible deniability’ involved in warranting or defending statements about minorities against accusations of racism. We discuss implications of symbolic politics for minorities who are perceived to have violated societal norms, and show how nationalism is used as a framework for denying racist intent. Analyses of historical context show how ‘race’ forms only one lens from which to view issues of intergroup relations. While the press was sensitive to issues of racism, they demonstrated little awareness of concurrent issues of neo‐liberal economics, or market fundamentalism. Anti‐racism may be motivated not only by the ideals of egalitarianism, but also by underlying dynamics of economic power in a global economy. Copyright © 2006 John Wiley & Sons, Ltd.
