Achromatic color matching as a function of apparent target orientation,target and background luminance,and lightness or brightness instructions

In two experiments, achromatic color matches for a fixed target, under constant illumination, were compared under conditions where the target appeared perpendicular to illumination direction and coplanar with the background (monocular viewing) and where the target appeared nonperpendicular to illumination direction and noncoplanar with the background (binocular viewing). Contrary to the coplanar ratio hypothesis, which predicts a “lightening” of the target seen coplanar with a darker background, a general “darkening” of the target occurred for both white (N9.5/) and black (N3/) backgrounds and for both dark (N5.5/) and light (N6.5/) targets. This darkening effect was greatest for the darker target and black background, and approximately equal for other combinations of target value and background. The direction of the darkening effect is consistent with the albedo hypothesis, which assumes an inferential correction for changes in conditions of illumination. However, variation in the magnitude of the darkening effect is problematical, and cannot be easily explained by any existing theory. In both experiments, instructions to judge “lightness” or “brightness” failed to produce any substantial differences in performance, although postexperimental questioning suggested that subjects had a verbal understanding of these concepts. Apparently, under reduction conditions, subjects lack cues to illumination and make only lightness matches, regardless of instructions.     

Repeating the target neither speeds nor slows its detection: Evidence for independent channels in letter processing

A target letter at a predesignated location typically is identified less readily when extraneous letters are added to the display. This disruption has been attributed to lateral interference via interactive or inhibitory channels or to attempts to encode the string as a unit. In the present study, subjects saw a single letter (e.g., B), a repeated-letter string (e.g., BBBB), or an extraneous-letters string (e.g., BCLD) and had to decide whether the leftmost letter in the string matched a target letter. Since trials were blocked by string type, letter position did not have to be discriminated on repeated-letter trials, nor was response competition present on those trials. With normal letter spacing, RT was virtually the same on repeated-letter trials as on single-letter trials. (Increasing the letter spacing in Experiment 3 did produce a slight, but nonsignificant, 22-msec increment on the repeated-letter trials.) The results indicate that individual letters are perceived as such just as well when presented in a group as when presented individually and thus provide support for the parallel, independent-channels model.     

The stability and clinical significance of distress: A rejoinder to pepper and coyne

Past research has established that some individuals with high Beck Depression Inventory (BDI) scores at one time point have scores that are lower at a second time point. Recently, we provided evidence indicating that the temporal instability of certain BDI scores may be due partly to the regression to the mean phenomenon. Pepper and Coyne (1996) question this statistical interpretation; they argue that distress among students is unstable for substantive reasons. In the current paper, we reaffirm our view that statistical and measurement factors may account, in part, for changes in BDI scores over time. Given this possibility, inferences about distress or depression as a latent construct in student samples are not warranted if these inferences are based on the administration of a single instrument such as the BDI; any conclusions about distress as a psychological construct must be qualified by acknowledging the possible roles of error and method variance. Clearly, empirical research is needed in order to obtain a better understanding of the nature of distress as a latent variable, especially in light of evidence which indicates that subthreshold levels of depression have a high degree of clinical significance.     

The Development and Validation of the Multicomponent AIDS Phobia Scale

The development, reliability, and validity of a new instrument, the Multicomponent AIDS Phobia Scale (MAPS), is described. Based on a sample of 181 university students, the results indicate that the MAPS has strong internal consistency and moderate test-retest reliability. In addition, an assessment of concurrent and discriminant validity indicates statistically significant correlations with other self-report measures of anxiety, hypochondriasis, obsessive-compulsive disorder, and fear of AIDS. The results of a factor analysis indicate that the scale consists of two factors: Fear of Infection and Fear of Others/Avoidance. Although further research with the MAPS in a clinical population is warranted to investigate the generalizability of this study's results, the instrument appears to be a reliable and valid measure of AIDS Phobia and may prove useful for improving clinical assessment and documenting treatment outcome.     

The word-superiority effect and phonological recoding

Previous work indicates that the locus of the word-superiority effect in letter detection is nonvisual and that letter names, but not letter shapes, are more accessible in words than in nonwords, that is, scrambled collections of letters (e.g., Krueger & Shapiro, 1979; Krueger & Stadtlander, 1991; Massaro, 1979). The nonvisual (verbal or lexical) coding may be phonological, or it may be more abstract. In the present study, a word advantage in the speed of letter detection was found even when the target letter was silent in the six-letter test word (e.g., s in island). Other test words varied in their frequency of occurrence in English and number of syllables (1, 2, or 3). The word advantage was larger for higher frequency words but was not affected by syllable length. The presence of unpronounceable nonwords and silent letters in the words discouraged reliance upon the phonological code but did not thereby eliminate the word advantage. Thus, the word-superiority effect with free viewing is not based entirely upon phonological recoding.

Completed suicide in the gifted: a late comment on "suicide among gifted women".

A recent study by Tomlinson-Keasey, Warren, and Elliott (1986) found differences between completed suicides in Terman's sample of gifted children and comparison subjects. The present article suggests that the differences identified in Tomlinson-Keasey et al. may have been confounded by the fact that completed suicides are typically found to have higher levels of psychiatric disturbance than nonsuicides. Data are presented to illustrate that when the completed suicides in Terman's sample are matched for psychiatric disturbance with the comparison subjects, few differences are found.

Development and Validation of the Homophobia Scale

This study describes the development and validation of the Homophobia Scale. The scale was developed to assess the cognitive, affective, and behavioral components of homophobia. The participants (n=321 for the field trials and n=122 for test–retest reliability) were college students from a large Midwestern university. Results yielded a 25-item questionnaire consisting of three factors: a factor that assesses mainly negative cognitions regarding homosexuality, a factor that assess primarily negative affect and avoidance of homosexual individuals, and a factor that assesses negative affect and aggression toward homosexual individuals. Concurrent validity was established using The Index of Homophobia (Hudson & Ricketts, 1980). The phases of scale development and implications of the results are discussed.     

External versus internal attributions in suicide and their implications for crisis intervention and suicide prevention

The concept of belief of locus of control is explored for its relevance in crisis intervention and suicide prevention. Although research into the association has produced inconsistent findings, the counselor has rich possibilities for intervention, especially if belief in locus of control is explored along with feelings of powerlessness and helplessness.
