Reasoning with realistic disjunctives

The research reported here investigated how people interpret and reason with disjunctive statements. Experiment 1 demonstrated a general preference for exclusive over inclusive interpretations, although this varied as a function of the context in which the statement occurred, and there were some contexts in which other, quite different, interpretations were possible. Experiments 2 and 3 showed that the logical inferences subjects would draw from disjunctive statements also varied with context. It is concluded that or permits a number of different interpretations, which are determined by contextual cues. Previous research may have underestimated disjunctive reasoning performance by using contexts that lead to non-logical responses; certainly in the present experiments reasoning was generally accurate given the interpretation adopted.     

Ready for prime time: Network series devoted to working women in the 1980s

The recent ascendancy of several female producers in male-dominated Hollywood has refocused attention on the portrayal of women on television. This paper addresses trends in network series featuring working female leads during the 1980s, assessing the influence of economic factors (e.g., producer, network) in shaping these portrayals. Results suggest that the networks offered comparable levels of female-lead series, with CBS maintaining a slight lead, owing to prior successes with the format. The number and professional range of criterion series increased through the 1980s — particularly after 1985 — when competition from other carriers (e.g., cable) intensified. A corollary decline of generalized “mass-audience” fare has freed the networks to pursue the female “18–49” demographic in earnest, with a greater frequency and range of working woman portrayals.     

Sex differences in the adolescent brain

Adolescence is a time of increased divergence between males and females in physical characteristics, behavior, and risk for psychopathology. Here we will review data regarding sex differences in brain structure and function during this period of the lifespan. The most consistent sex difference in brain morphometry is the 9–12% larger brain size that has been reported in males. Individual brain regions that have most consistently been reported as different in males and females include the basal ganglia, hippocampus, and amygdala. Diffusion tensor imaging and magnetization transfer imaging studies have also shown sex differences in white matter development during adolescence. Functional imaging studies have shown different patterns of activation without differences in performance, suggesting male and female brains may use slightly different strategies for achieving similar cognitive abilities. Longitudinal studies have shown sex differences in the trajectory of brain development, with females reaching peak values of brain volumes earlier than males. Although compelling, these sex differences are present as group averages and should not be taken as indicative of relative capacities of males or females.     

I Listen,Therefore I Am: An Asian American Approach to Post‐Materialist Living

Abstract : Consumerism is a cultural atmosphere that permeates societies when they are saturated with market‐driven values at the expense of social values. It prioritizes personal needs over the common good and reduces even religion to a “brand” that people wear like an emblem. It simultaneously approaches the world itself as a resource to be managed, forgetful of the fact that all living beings are songs and stories worth hearing. As Christianity becomes a post‐western religion, opportunities emerge for Christians to develop cross‐cultural poetics that are conducive to post‐materialist ways of living in the world. Poetics are not theologies, but rather outlooks on life or, perhaps more appropriately, ways of listening to the voices of people and other living beings. The purpose of this essay is to propose one such Asian American theology that can be a commitment to deep listening: that is, to dwelling musically in the world. This manner of dwelling can recognize that even the heart of the universe—even God—is a listening presence at the heart of the universe.     

Effects of reducing attentional demands on performance of reading comprehension tests by third graders

The researchers examined the effects of reducing attentional demands on reading comprehension test scores. Third grade students (N=939) completed two forms (T & S) of the Stanford 9 Reading Comprehension Test (54 items, 50 min.) in the spring of 1999. Form T (state-mandated) was administered following standardized procedures in one session. Form S (alternate) was administered in multiple, divided-time sessions, that is, the total test time and items were divided in halves and thirds per session to lessen attentional demands. A repeated-measure analysis of variance yielded significant effects for average and low readers. A resource match explanation and a metacognitive explanation are offered for the results, and educational implications are discussed.     

A depressive symptom scale for the California Psychological Inventory: construct validation of the CPI-D

To facilitate life span research on depressive symptomatology, a depressive symptom scale for the California Psychological Inventory (CPI) is needed. The authors constructed such a scale (the CPI-D) and compared its psychometric properties with 2 widely used self-report depression scales: the Beck Depression Inventory and the Center for Epidemiological Studies Depression Scale. Construct validity of the CPI-D was examined in 3 studies. Study 1 established content validity, classifying CPI-D items into Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition depressive symptoms. Study 2 used 3 large samples to gather evidence for reliability and validity: correlational analyses demonstrated alpha reliability and convergent and discriminant validity; factor analysis provided evidence for discriminant validity with anxiety; and regression analyses demonstrated comparative validity with existing standard PI scales. Study 3 used clinician ratings of depression and anxiety as criteria for external validity.
