Right hemispheric specialization for mental imagery: A review of the evidence

An implicit assumption in the literature on functional hemispheric asymmetry is that the right hemisphere plays a special role in mental imagery. Using a definition of mental imagery as quasi-perceptual experience, we draw distinctions among visual imagery, visual recognition memory, and visuospatial abilities. We then review the research literature to evaluate the hypothesis that mental imagery is a specialized function of the right cerebral hemisphere, and find that it receives little unambiguous support. Case reports of loss of imagery are no more frequent with right than with left unilateral brain damage. Systematic studies of brain-injured patients provide some support for the hypothesis, but are also consistent with the alternative hypothesis of bilateral representation of imagery. Commissurotomized patients report dreaming and being able to form visual images. Behavioral and psychophysiological studies of non-brain-injured patients either fail to provide evidence in favor of the hypothesis or can be interpreted as compatible with the alternate hypothesis of bilateral hemispheric involvement in imagery. We conclude that there is, presently, insufficient empirical basis for considering imagery a right hemispheric function. We then discuss implications of this conclusion for future research.     

Facets of Emotional Clarity and Suspiciousness

In a college student sample, we explored the relations between individual differences in facets of emotional clarity and suspiciousness. Previous theory and research has treated emotional clarity as a one-dimensional construct. Boden and Berenbaum (2011) proposed that a second facet of emotional clarity, source awareness (a general understanding of the cause of their emotions), could be distinguished from type awareness (a general understanding of the type of emotions [anger, fear] experienced). We found that source and type awareness were incrementally, inversely associated with suspiciousness when statistically accounting for the extent to which emotions are attended to, and gender. Additionally, source awareness significantly predicted suspiciousness after accounting for anger, anxious arousal, and social anxiety, whereas type awareness did not. Findings are consistent with the hypothesis that, among individuals with low source and type awareness, suspicious beliefs are formed to make sense of and explain emotional arousal.     

Intercultural (Mis)Communication: Why Would You “Out” Me in Class?

This paper conceptualizes Hopson’s notion of crash moments by exploring an intercultural interaction (between an individual who identifies as heterosexual and another who identifies as homosexual) within a graduate classroom by drawing on cultural schema theory and critical incident analysis. Ultimately, this paper deconstructs a communication breakdown through a self-reflexive process in which the researcher was “outed” (someone else disclosed the sexual orientation of a lesbian, gay, bisexual or transgendered individual in a public setting) by a classmate—which the researcher deems as a problematic occurrence, making the incident critical and fitting for analysis within an intercultural communication context. This paper also considers the complexities of sexual identity negotiation as an African American female lesbian at a Historically Black College/University.     

An assessment of the similarities between a measure of positive perfectionism and a measure of conscientious achievement striving

Objectives

The purpose of the study was to examine the similarities between the constructs measured by the positive perfectionism subscale from the Positive and Negative Perfectionism Scale and the achievement striving subscale from the Revised NEO Personality Inventory.

Design

A non-experimental design was adopted.

Method

One-hundred and seventy-nine junior basketball players (age M = 16.50, s = 1.12) completed measures of positive perfectionism, conscientious achievement striving and other external measures.

Results

Analyses revealed that the two scales were highly positively correlated and demonstrated a similar pattern of relationships with the external measures. However, a single latent factor model provided a comparatively poorer fit than a two latent factor model.

Conclusions

There is some evidence that the positive perfectionism and achievement striving constructs measured by the scales in this study are distinguishable as two distinct factors in a confirmatory factor analysis; however, more empirical evidence is needed to establish their substantive differences.     

An Aristotelian Doctrine of the Mean in the Mencius?

Contrary to appearances, Mencius does not deploy anything like the Aristotelian doctrine of the mean to describe Boyi, Yi Yin, and Liu Xiahui. While Confucius’ actions are intermediate between the actions of these three sages, the sages’ character traits do not bracket Confucius’ character traits. Instead, the failings of the three sages are skew to each other. Boyi lacks righteousness; Yi Yin lacks benevolence; and Liu Xiahui lacks wisdom. The comparison of the sages centers on the question of when to resign an advisory position. According to Mencius, one should resign only if one’s advice will not be heeded, or if declining to resign would somehow lead to wrongdoing. Associating with wrongdoers and benefiting from the wrongdoing of others might lead to wrongdoing. Wrong motives might distort one’s advice. Insults from the advisee might be evidence of the futility of giving advice. But in themselves, fastidiousness, non-benevolent motives, and mistreatment by the advisee are not legitimate reasons to resign.     

Selecting the Better Model by Using Data,Occam's Razor,and a Little Common Sense: Reply to Ericsson

The issue is which model, practice‐alone or innate talent affecting learning speed and limiting asymptotic performance level, better accounts for expertise development in international chess. The innate talent model does much better by the usual criteria. A study to determine what innate talent for chess might consist is now needed. Copyright © 2012 John Wiley & Sons, Ltd.     

Longitudinal Effects of Different Types of Practice on the Development of Chess Expertise

A view holds that expertise level depends on practice alone and that certain types of practice are important or unimportant. Supporting evidence largely comes from studies using a correlational retrospective recall paradigm, usually with small samples. Initially, these studies were partially replicated with 533 international chess players. Log number of games played was the strongest predictor of latest performance rating. Then, effects of study hours, having had coaching and the number of games played were examined longitudinally to control for key variables confounded in the retrospective recall paradigm. Groups with a nearly 5–1 median difference in weekly study hours, roughly equated on time in the domain and the number of games played, were observed over 7 years. More study hours had negligible impact. Coaching had some effect over time, and the number of games had a strong effect even when participants were equated on time in the domain. Previous studies show that a factor other than the number of games is important in developing chess expertise. Study is a weak factor at best and could not be that important factor. Chess expertise apparently does not depend on practice (study and the number of games) alone. Copyright © 2011 John Wiley & Sons, Ltd.     

Protecting Against Low‐Probability Disasters: The Role of Worry

We carry out a large monetary stakes insurance experiment with very small probabilities of losses and ambiguous as well as exact probabilities. Many individuals do not want to pay anything for insurance whether the probabilities are given exactly or are ambiguous. Many others, however, are willing to pay surprisingly large amounts. With ambiguity, the percentage of those paying nothing is smaller and the willingness to pay (WTP) of the other individuals larger than with exact probabilities. Comparing elasticities with ambiguity, we find that worry is much more important than subjective probability in determining WTP for insurance. Furthermore, when the ambiguous loss probability is increased by a factor of 1000, it has almost no effect on WTP. Copyright © 2011 John Wiley & Sons, Ltd.
