RIGHTS AND RESPONSIBILITIES ON THE HOME PLANET

Abstract. Earth is the home planet, right for life. But rights, a notable political category, is, unfortunately, a biologically awkward word. Humans, nonetheless, have rights to a natural environment with integrity. Humans have responsibilities to respect values in fauna and flora. Appropriate survival units include species populations and ecosystems. Increasingly the ultimate survival unit isglobal; and humans have a responsibility to the planet Earth. Human political systems are not well suited to protect life atglobal ranges. National boundaries ignore important ecologicalprocesses; national policies do not favor an equitable distribution of sustainable resources. But there are signs of hope.     

Authorial intentions and metaphor comprehension

Three experiments investigated the role of authorial intentions in metaphor comprehension. In these studies, subjects read metaphoric (e.g., A family album is like a museum), literal (e.g., An art gallery is like a museum), and anomalous (e.g., A tortoise shell is like an art gallery) comparisons and rated their degreeof meaningfulness (Experiment 1), made speeded decisions as to whether each phrase was meaningful or not (Experiment 2), or wrote out interpretations of each comparison statement (Experiment 3). The subjects were tolt that the comparisons were written either by famous 20th century poets or by a computer program that randomly generated the statements from a list of words. Our general hypothesis was that knowing that intentional agents (the poets) authored the different comparisons should facilitate subjects' comprehension of the metaphors. Experiment 1 showed that subjects rated both metaphoric and literal comparisons as being more meaningful in the poet condition than when these statements were supposedly written by computer. Experiment 2 demonstrated that subjects were faster in making their meaningfulness judgments for metaphors in the poet condition than in the computer context, but that subjects were also slower in rejecting anomalous comparisons when these were supposedly written by the poets. Experiment 3 indicated that subjects produced more meanings or interpretations for comparisons presumably written by poets than by computer. These results highlight the improtance of implied, authorial intentions in understanding metaphorical statements. We discuss the implications of this work for psycholinguistic theories of figurative language comprehension, as well as for theories of literary interpretation.     

Judgment processes in motivation: Anchoring and adjustment effects on judgment and behavior

The behavioral correlates of human judgment have received little attention from judgment and decision making researchers. One behavioral domain that provides for the study of judgment-behavior relations is task motivation (i.e., the allocation of time and effort to a task). Judgments of contingent relations are primary components of several theories of motivation, including expectancy theories and the theory of behavior in organizations proposed by Naylor, Pritchard, and Ilgen (1980). The characteristics of heuristic judgment processes are hypothesized to affect contingency judgments and thus behavioral allocations of time and effort. This paper examines the effects of the anchoring and adjustment heuristic upon (a) judgments of future effort and performance and (b) upon actual allocations of time and effort using several types of anchoring information. Results indicate that both irrelevant and relevant information have strong anchoring effects on effort and performance judgments, but do not have concomitant effects on behavior. Implications for the role of judgment in motivation and for the link between judgment and behavior are discussed.     

ETHNIC GROUP DIFFERENCES IN COGNITIVE ABILITY IN EMPLOYMENT AND EDUCATIONAL SETTINGS: A META-ANALYSIS

The cognitive ability levels of different ethnic groups have interested psychologists for over a century. Many narrative reviews of the empirical literature in the area focus on the Black-White differences, and the reviews conclude that the mean difference in cognitive ability ( g ) is approximately 1 standard deviation; that is, the generally accepted effect size is about 1.0. We conduct a meta-analytic review that suggests that the one standard deviation effect size accurately summarizes Black-White differences for college application tests (e.g., SAT) and overall analyses of tests of g for job applicants in corporate settings. However, the 1 standard deviation summary of group differences fails to capture many of the complexities in estimating ethnic group differences in employment settings. For example, our results indicate that job complexity, the use of within job versus across job study design, focus on applicant versus incumbent samples, and the exact construct of interest are important moderators of standardized group differences. In many instances, standardized group differences are less than 1 standard deviation. We conduct similar analyses for Hispanics, when possible, and note that Hispanic-White differences are somewhat less than Black-White differences.     

MRI-Assessed Volume of Cerebellum Correlates with Associative Learning

Richard F. Thompson's cerebellar model of classical eyeblink conditioning highlights Purkinje cells in cerebellar cortex and principal cells in the deep cerebellar nucleus as the integrating cells for acquisition of conditioned responses (CRs). CR acquisition is significantly slower in rabbits with lesions to cerebellar cortex and in Purkinje cell-deficient mice that lose all cerebellar cortical Purkinje cells. Purkinje cells are the largest neurons in the cerebellum and contribute significantly to cerebellar volume. Magnetic resonance imaging (MRI) was used to assess cerebellar volume in humans. Cerebellar volume was related to eyeblink conditioning (400-ms delay procedure) in 8 adults (21-35 years) and compared to 8 older adults (77-95 years) tested previously (Woodruff-Pak, Goldenberg, Downey-Lamb, Boyko, & Lemieux, 2000). In the young adult sample, there was a high correlation between percentage of CRs in a session and cerebellar volume (corrected for total intracranial volume [TIV], r =.58, p =.066). There were statistically significant age differences in cerebellar volume, t(14) = 8.96, p <.001, and percentage of CRs, t(14) = 3.85, p <.002, but no age difference in TIV. Combining the young and older adult sample, the correlation between percentage of CRs and cerebellar volume (corrected for TIV) was.832 (p <.001). Cerebellar volume showed age-related deficits likely due to Purkinje cell loss. Individual differences in classical eyeblink conditioning are associated with differences in cerebellar volume, supporting Thompson's model of a cerebellar cortical role in facilitating this form of associative learning.     

Closeness to God Among Those Doing God’s Work: A Spiritual Well-Being Measure for Clergy

Measuring spiritual well-being among clergy is particularly important given the high relevance of God to their lives, and yet its measurement is prone to problems such as ceiling effects and conflating religious behaviors with spiritual well-being. To create a measure of closeness to God for Christian clergy, we tested survey items at two time points with 1,513 United Methodist Church clergy. The confirmatory factor analysis indicated support for two, six-item factors: Presence and Power of God in Daily Life, and Presence and Power of God in Ministry. The data supported the predictive and concurrent validity of the two factors and evidenced high reliabilities without ceiling effects. This Clergy Spiritual Well-being Scale may be useful to elucidate the relationship among dimensions of health and well-being in clergy populations.
