Lateralization of temporal lobe dysfunction and verbal encoding

The contribution of encoding deficits to verbal-learning difficulties known to be associated with temporal lobe dysfunction was investigated. Auditory and visual false-recognition tasks, which assess verbal encoding strategies, were given to patients with left-temporal-lobe (LTL) and right-temporal-lobe (RTL) surgical excisions and to a group of normal controls (NC). On both auditory and visual tasks, LTL patients made significantly more false-recognition errors than the other subjects on related, but not unrelated, words in the test list. The findings indicate that LTL patients are able to initially encode verbal material and that a breakdown in information processing occurs at a later stage. On the auditory tasks, the performance of RTL patients did not differ from that of NC subjects. However, on the visual tasks, RTL patients, as compared to both LTL and NC subjects, made fewer false-recognition errors. The performance of RTL patients, in contrast to LTL patients, could be interpreted as a reduced encoding of the visual attribute of verbal material. Another possible explanation considered was difficulty in familiarity discrimination.     

How rejection of essences expresses despair

The Self and the ego in Jung's psychology are an instance of what Edmund Husserl called a 'double intentionality': one tending toward meaning is distinct from another tending toward meaning, yet they are reciprocally inseparable from each other. As perception in a present moment and memory of a past are impossible without each other, so an intending of ego and that of Self are impossible without each other. Accompanying the ego (mostly in the background) during each moment of time is a tending towards a particular Idea or essence. This reciprocity is expressed in a unique way over a lifetime and is like the relation of mother and child, and so it is important for all of us born of women to retain a sense of essences and the fullness of Self. 'Constructivism', however, is a current belief held by some feminists, and it influences both theorizing and practice in analytical psychology. It involves a rejection of essences, a revision of Jung's Idea of Self, and an attempt to conduct analysis without reference to an intentional subjective Self. Such constructivist revision expresses a despair both about essences as Ideas and about Self as intentional and subjective. It is despair over Self in a Kierkegaardian sense.     

Religion and Science Conversation: A Case Illustration

The March 1999 issue of Zygon provides a case illustration of a religion-and-science conversation. The three responses to the issues raised by The Humanizing Brain represent a spectrum ranging from skepticism to affirmation. Each is examined in turn. Next, we present a constructive set of guidelines beginning with the recognition that interdisciplinary talk requires stretching disciplinary language into metaphor and analogy. We conclude with a methodology emphasizing empiricism and wholism.     

Risk perception as a function of risk exposure amongst rock climbers

ObjectivesThe first objective was to examine the extent to which climbers' climbing safety perceived competence (CSPC) and perceived own absolute (POAR) and comparative (PCR) risk of getting seriously injured whilst climbing is related to risk exposure. The second objective was to examine which variables influence POAR and PCR.MethodTwo hundred and thirty-five climbers (M = 32, SD = 10.2 years of age) completed the following questionnaires: a CSPC scale specifically developed to assess perceived ability to practice climbing safely; indirect measures of PCR, consisting in the subtraction of the participants' assessment of their own risks from their assessment of other climbing referents' risks; and the Life Orientation Test-Revised, measuring dispositional optimism (DO). Participants were approached in their practices sites from Mediterranean regions, and were divided into groups based on their climbing practice's risk exposure; that is, high risk: traditional climbing (TRAD; n = 42); moderate risk: leading (LEAD; n = 89); and low risk: either top-roping (TOP; n = 51) or indoor bouldering (IND; n = 53).ResultsAnalyses of variance showed that TRAD expressed higher CSPC and higher POAR than the other groups. PCR also differed amongst the groups. More specifically, TRAD expressed comparative pessimism and LEAD expressed comparative optimism, as their POAR was, respectively, higher and lower than their perceived average climber's risk. TOP and IND perceived their own risk in a similar way to that of the average climber. Regression analyses showed that DO did not influence POAR or PCR. Past injury episode was positively related to POAR and negatively related to the propensity to express comparative optimism, though only amongst TRAD and LEAD.ConclusionsClimbers' risk perception accurately reflected their risk exposure. Climbers whose climbing modality involves higher risks acknowledged so when evaluating their own absolute and comparative risks of getting seriously injured whilst climbing.     

Gender and Ethnic Differences in Stress Reduction, Reactivity, and Recovery

To assess whether gender and ethnic subgroups differentially self-reported stress reduction, reactivity, and recovery, 313 undergraduate African American and Caucasian students at an urban northeastern American university were randomly assigned to one of three relaxation conditions which they utilized before and after being exposed to a visual stressor. Self-report measures of state anxiety were taken before and after each activity. Females reported the most stress reduction, reactivity, and recovery. Caucasian females reported unique reactions relative to other groups at all phases. African American males reported the least amount of cognitive reactivity. Results from this study suggest that ethnicity should be evaluated with gender differences, affective reactions need to be better understood, and interventions for stress may need to be specifically tailored.     

Increased sensitivity to the disinhibiting effects of alcohol in binge drinkers.

Heavy episodic alcohol use, or binge drinking, is a serious public health problem. Binge drinking is endemic in college students and has resulted in numerous alcohol-related tragedies, including acute alcohol poisonings, falls, and automobile collisions. Such negative outcomes might occur because binge drinkers are generally more impulsive, and this impulsivity might be exacerbated under alcohol. The purpose of this study was to examine this hypothesis by comparing the acute effects of alcohol on a cognitive measure of behavioral control in binge and nonbinge drinkers. The results indicated that binge drinkers act more impulsively and report feeling more stimulated under an acute 0.65 g/kg dose of alcohol compared to nonbinge drinkers. The present finding of a heightened disinhibitory reaction to alcohol in binge drinkers may help explain the link between impulsivity and problem drinking at a more fundamental level of behavioral control.     

Factor structure of the Smith irrational beliefs inventory: results of analyses on six independent samples

This study reports the results of six factor analyses (alpha factoring, direct oblimin rotation, Delta= .4) on six items from the Smith Irrational Beliefs Inventory. Six independent samples of 1851 college students (521 men, 1,280 women, 50 sex unstated) were tested. Three factors emerged with identical content for each analysis. Distorted Egocentrism was defined by two items reflecting feelings of entitlement and the naive assumption that events should always turn out favorably the way one desires; Task Exaggeration/Catastrophizing was defined by two items directly depicting a tendency to view challenges as overwhelming and catastrophic; and Isolated Low Self-esteem was defined by two items expressing the feeling that one has unacceptable feelings that could lead to isolation or rejection. Previous research on other irrational belief inventories has yielded inconsistent results, with multifactorial solutions emerging for clinical samples and unifactoral solutions for student samples. That the present six factor analytic studies yielded a consistent multifactoral set of irrational beliefs for a very large student sample suggests that factors do emerge when items are initially screened and the subject population is carefully defined.     

On Community Leadership: Stories About Collaboration in Action Research

This article provides an account of a 10-year collaborative documentation of community leadership in an African American community on the South side of Chicago. The stories are oriented to several critical incidents in the life course of the collaboration. They are told from the perspectives of one university professor, four graduate students, and one community leader. Together they provide an account of how this research was shaped by the interactions of the research team with members of the community, how research questions emerged, methodologies were developed, ways of gathering data were tried and tested, and interpretations of data unfolded. Special attention is given to the ways in which the process and products of this research contributed to the community's own process of leadership development. The stories also discuss the various roles participants in this collaboration played both in the academic arena and in the community, and how they experienced gender, race, nationality, and social status.     

Competition and cooperation in the five-factor model: individual differences in achievement orientation

The authors investigated the relationship between basic achievement orientations of competition and cooperation and the five-factor model of personality as measured by the Revised NEO Personality Inventory (NEO-PI-R; P. T. Costa & R. R. McCrae, 1992). They examined 2 types of competition: hypercompetition (R. M. Ryckman, B. Thornton, & J. C. Butler, 1994) and personal development competition (R. M. Ryckman, M. Hammer, L. M. Kaczor, & J. A. Gold, 1996), as conceptualized by K. Horney (1937). In a sample of 251 young adults, 14% to 38% of the variance in achievement orientations was collectively predicted by NEO-PI-R domain scales. Of NEO-PI-R predictors, Agreeableness was most important in characterizing differences between various achievement orientations; Agreeableness was negatively related to hypercompetition, positively related to cooperation, and unrelated to personal development competition. Extraversion was positively related to both cooperation and personal development competition but was unrelated to hypercompetition. In contrast, Openness and Conscientiousness were least helpful in differentiating among achievement orientations. These findings support the useful application of the NEO-PI-R in achievement research and highlight competition and cooperation as interpersonally laden achievement orientations.     

Sample size planning for the standardized mean difference: accuracy in parameter estimation via narrow confidence intervals

Methods for planning sample size (SS) for the standardized mean difference so that a narrow confidence interval (CI) can be obtained via the accuracy in parameter estimation (AIPE) approach are developed. One method plans SS so that the expected width of the CI is sufficiently narrow. A modification adjusts the SS so that the obtained CI is no wider than desired with some specified degree of certainty (e.g., 99% certain the 95% CI will be no wider than omega). The rationale of the AIPE approach to SS planning is given, as is a discussion of the analytic approach to CI formation for the population standardized mean difference. Tables with values of necessary SS are provided. The freely available Methods for the Behavioral, Educational, and Social Sciences (K. Kelley, 2006a) R (R Development Core Team, 2006) software package easily implements the methods discussed.
