Refining the understanding of inhibitory processes: how response prepotency is created and overcome

Understanding (a) how responses become prepotent provides insights into when inhibition is needed in everyday life. Understanding (b) how response prepotency is overcome provides insights for helping children develop strategies for overcoming such tendencies. Concerning (a), on tasks such as the day‐night Stroop‐like task, is the difficulty with inhibiting saying the name of the stimulus due to the name being semantically related to the correct response or to its being a valid response on the task (i.e. a member of the response set) though incorrect for this stimulus? Experiment 1 (with 40 4‐year‐olds) suggests that prepotency is caused by membership in the response set and not semantic relation. Concerning (b), Diamond, Kirkham and Amso (2002) found that 4‐year‐olds could succeed on the day‐night task if the experimenter sang a ditty after showing the stimulus card, before the child was to respond. They concluded that it was because delaying children’s responses gave them time to compute the correct answer. However, Experiment 2 (with 90 3‐year‐olds) suggests that such a delay helps because it gives the incorrect, prepotent response time to passively dissipate, not because of active computation during the delay.     

Lexical ambiguity and the timecourse of attentional allocation in word recognition

In two experiments the allocation of attention during the recognition of ambiguous and unambiguous words was investigated. In Experiment 1, separate groups performed either lexical decision, auditory probe detection, or their combination. In the combined condition probes occurred 90, 180, or 270 ms following the onset of the lexical-decision target. Lexical decisions and probe responses were fastest for ambiguous words, followed by unambiguous words and pseudowords, respectively, which indicated that processing ambiguous words was less attention demanding than unambiguous words or pseudowords. Attention demands decreased across the timecourse of word recognition for all stimulus types. In Experiment 2, one group performed the lexical-decision task alone, whereas another group performed the lexical-decision task during the retention interval of a short-term memory task. The results were consistent with those from Experiment 1 and showed that word recognition is an attention-demanding process and that the demands are inversely related to the number of meanings of the stimulus. These results are discussed with regard to the structure of the mental lexicon (i.e., single vs. multiple lexical entries) and the effect of such a structure on attentional mechanisms.     

The daughters of charlotte ray: The career development process during the exploratory and establishment stages of black women attorneys

This exploratory study examines the career development process of Black women in the legal field. The purpose of the study was to gain an understanding of the factors that enable minority women to enter atypical professions and overcome the dual discriminatory obstacles of race and sex. The specific objectives of the study were to determine the impact of sociocultural variables on the career choice process of minority women during the career entry and establishment stages (Super, 1957). The study was focused on the influence of educational values in the home; economic resources of the family, significant role models, legislated educational parity policies such as Brown vs. Board of Education, university affirmative action, and minority recruitment programs.This study was written as part of a grant from the Rockefeller Foundation.     

The precarious enterprise of ministry

The effect of the cultural values of rationalization and individualism upon the status of the parish minister is discussed. These values make the minister's status precarious because role behavior is difficult to interpret in terms of them. Some defenses against precariousness are outlined.This paper was read at the session, Ministry Studies: The Contribution of Samuel W. Blizzard, convened at the annual meeting of the Religious Research Association, Milwaukee, Wisconsin, October 1975. The late Samuel Wilson Blizzard was Maxwell M. Upson Professor of Christianity and Society at Princeton Theological Seminary.     

Development of a Scale Measuring Genetic Variation Related to Expressive Control

ABSTRACT It has been theorized that a substantial genetic component underlies the Self-Monitoring Scale. The identity of this component, however, is not yet known. In order to identify and better understand it, a more precise measure of the component is required. The present research attempted to ( a ) identify an axis of the self-monitoring two-factor space with maximum genetic variance; and ( b ) bootstrap a scale more highly correlated with this genetic maximum than is the Self-Monitoring Scale using twins. Evaluation of the new scale against criteria of validity indicates that scale construction was reasonably successful. The new measure had a cross-validated monozygotic twin intraclass correlation of .76 and a dizygotic twin intraclass correlation of .16. This work yields a new research tool and suggests a new approach to personality assessment. Correlates of the new measure as well as theoretical and methodological issues relevant to the measurement of a latent genetic entity are discussed     

Depression and decision-making among intravenous drug users

Two short scales, the TCU Depression Scale and the TCU Decision-making Scale, were psychometrically evaluated in a sample of 145 intravenous drug users. Coefficient alpha reliabilities were .78 for the 6-item TCU Depression Scale and .77 for the 9-item TCU Decision-making Scale. Concurrent validity of the former scale was assessed by correlating scores with those on the Beck Depression Inventory, r = .75. Based on the Beck Depression Inventory Clinical cutoff scores, 83% of the sample showed some depression, with 23% severely depressed, 39% moderately depressed, and 21% mildly depressed. Individuals scoring higher on depression on both tests tended to score lower on decision-making. Significant demographic associations of age, gender, education, and race-ethnicity were found for the depression and decision-making scales. More depression was noted for women, those younger, white, and having less education. Older and more educated intravenous drug users tended to score higher on decision-making. Validity for the depression and decision-making scales was assessed by examining correlations with behaviors. Significant positive correlations were found between depression scores and intravenous use of cocaine only, heroin and cocaine combined, and heroin only. Also, intravenous use of cocaine only and of cocaine and heroin combined were negatively related to decision-making. AIDS sex-risky behavior was positively correlated with depression and negatively correlated with decision-making.
