The functional role of attention for spatial coding in the Simon effect

Summary Two experiments investigated relative spatial coding in the Simon effect. It was hypothesized that relative spatial coding is carried out with reference to the position of the focus of visual attention. The spatial code for an imperative stimulus presented exactly at the position of focal attention should be neutral on the horizontal plane, and therefore no Simon effect should be observed. However, when the imperative stimulus is presented to the left or to the right of the current position of focal attention, the spatial code should not be neutral, thus producing a Simon effect. In both experiments, focal attention was manipulated either by a peripherally presented onset precue (Experiment 1) or by a centrally presented symbolic precue (Experiment 2). Results showed that the Simon effect was substantially reduced in both experiments when a valid precue preceded the imperative stimulus just in time to conclude refocusing of attention to the position of the imperative stimulus before it was presented. However, conditions with neutral precues yielded a normally sized Simon effect. In both experiments, the Simon effect decreased as the SOA grew when the precue was valid. At least for the Simon effect, the results can be interpreted as evidence that relative spatial coding is functionally related to the position of the focus of attention.     

The Relationship Between Racism and Racial Identity Among White Americans: A Replication and Extension

The purpose of this investigation was to assess the influence of White racial identity attitudes on racism. A total of 234 White undergraduate students participated in this investigation. The students completed the White Racial Identity Attitude Scale (Helms & Carter, 1990) and the New Racism Scale (Jacobson, 1985). Consistent with findings in previous research, White racial identity attitudes were predictive of racism. We also found gender and age differences in White racial identity attitudes. Implications of these findings are discussed in terms of the role of counselors in addressing racial awareness on college campuses.     

The Role of an Academic Department in Promoting Faculty Development: Recognizing Diversity and Leading to Excellence

The authors discuss the role of an academic department in promoting faculty development. Specifically, the authors (a) define faculty development from a departmental perspective, (b) discuss stages and seasons in academic careers, and (c) delineate specific faculty development goals and programs within the department.     

Examining the Association Between Self-Reported Multicultural Counseling Competencies and Demographic Variables Among Counselors

The authors examined the association between demographic variables and self-reported multicultural counseling competencies among counselors. A national sample of 220 counselors affiliated with university counseling centers participated in this investigation. Counselors responded to 40 Likert-type statements about multicultural awareness, knowledge, skills, and relationships. Results from a series of multivariate and univariate analyses indicated that Asian American and Hispanic counselors reported more multicultural knowledge than did White counselors, and African American, Asian American, and Hispanic counselors reported more competence in multicultural awareness and relationships than did White counselors. No effects were found for other demographic variables. Implications of these findings are discussed.     

DSM-IV: WhatY's New

The significant differences between the Diagnostic and Statistical Manual of Mental Disorders (DSM-III-R; American Psychiatric Association, 1987) and the DSM-IV (American Psychiatric Association, 1994) are described, focusing on the types of mental disorders counselors frequently diagnose and treat. These include several disorders included in the children's section as well as Adjustment Disorders, Substance-Related Disorders, Mood Disorders, Anxiety Disorders, and Personality Disorders.     

The Correlation of General Cognitive Ability and Psychomotor Tracking Tests

A study was conducted to investigate the nexus of cognitive and psychomotor tests as might be used for personnel selection and assessment. These two domains are frequently seen as independent. A multiple aptitude cognitive test battery and a psychomotor test battery were administered to 354 United States Air Force recruits. The average multiple correlation of the cognitive tests and each psychomotor score as a criterion was 0.34, corrected for range restriction. Confirmatory factor analyses disclosed general cognitive and general psychomotor factors, three lower-order psychomotor factors, and two lower-order cognitive factors. The general cognitive factor accounted for 39% of the variance and the general psychomotor factor accounted for 29% of the variance. Residualized, the lower-order factors accounted for between 10% and 3% of the variance. The average g saturations (loadings) of the cognitive and psychomotor tests were 0.82 and 0.34 respectively. An implication for personnel selection is that the incremental validity of psychomotor tracking tests beyond the validity of cognitive tests will be small due to the commonality of measurement. A further implication of findings is the need to study the validity of the general and specific psychomotor factors.     

An additional measure of availability derived from theOxford English Dictionary

In order to develop an additional measure of availability for the nouns from Paivio, Yuille, and Madigan’s (1968) list, we used a CD-ROM version of theOxford English Dictionary (OED) to obtain the number of times a word was used to define other words. This variable was added to Rubin and Friendly’s (1986) set of measures for these words. In multiple regression analyses, our measure proved to be a useful predictor of free recall. These results suggest that the OED may be useful for providing additional psycholinguistic measures.     

Teaching the Rescorla-Wagner model using STELLA-II

Although the Rescorla-Wagner model is widely taught in learning courses, most textbooks present a simplified version that does not contain all of its parameters. On the basis of Rescorla and Wagner 1972) and the Turbo PASCAL program by Lachnit, Schneider, Lipp, and Kimme! (1988), we created a simulation using STELLA-II, an icon-based program by High Performance Systems, Inc. We argue that this simulation facilitates teaching the complete Rescorla-Wagner model. Using trans-switching (Kimmel & Ray, 1978; Lachnit, 1986; Murrin & Kimmel, 1986) as an example, we demonstrate the effectiveness of the STELLA-II version of the Rescorla-Wagner model as a heuristic tool.     

Adaptation effects and reversible figures: A comment on Horlitz and O’Leary

In a recent article, Horlitz and O’Leary (1993) offer a reinterpretation of the results of several studies over the past 40 years that have employed the prolonged-inspection technique in the investigation of reversible figures. Specifically, they contend that, contrary to the favored interpretation of neural adaptation effects, the results of these studies reveal the combined influence of such topdown processes as attention and perceptual learning as well as such methodological difficulties as unwanted demand characteristics. In this note, we examine their analysis of the literature, their alternative theoretical model, and the supporting conclusions they draw from their two experiments. We argue that there is considerable evidence from a variety of studies for the joint role of bottom-up and top-down processes in reversible figures. Moreover, we propose that Horlitz and O’Leary’s own research, rather than eliminating the possibility of neural-adaptation effects, is best conceptualized as providing additional evidence for the role of higher-order processes in these phenomena.
