We See in the Dark

Do we need light to see? I argue that the black experience of a man in a perfectly dark cave is a representation of an absence of light, not an absence of representation. There is certainly a difference between his perceptual knowledge and that of his blind companion. Only the sighted man can tell whether the cave is dark just by looking. But perhaps he is merely inferring darkness from his failure to see. To get an unambiguous answer, I switch the focus from perceptual knowledge to non‐epistemic seeing. My conclusion is that we see even in the limiting case of absolute darkness – regardless of whether we believe we are seeing. We see little of pratical interest. But in terms of basic information, we see about as much as we do when the lights are on. Depending on what has gone before and after, we may even see ordinary objects.     

Dispositional Affectivity and Work-Related Outcomes: A Meta-Analysis

This study meta-analytically reviews the influence of individuals' dispositional negative affectivity (NA) and positive affectivity (PA) on a broad range of work-related outcomes grouped into 3 categories: (a) work attitudes; (b) workplace experiences; and (c) work behavior. Across cumulative studies, it was found that NA and PA demonstrated significant effects on most of these outcomes. Moreover, we found some interesting differences in NA's and PA's relationships with work outcomes. Specifically, while NA had more influence on variables pertinent to work stressors (e.g., role problems), PA demonstrated a stronger effect on variables related to positive job and organizational context (e.g., job autonomy, procedural justice). Implications for theory advancement and future research in this area are discussed.     

Subjective Distress to Violations of Trust in Mexican American Close Relationships Conforms to Evolutionary Principles

Sex differences in subjective distress to violations of trust in a close relationship were observed among Mexican American men and women. Imagining a partner’s emotional infidelity and other female-linked violations (for example, a partner who no longer desires to work) distressed a larger percentage of women than men. In contrast, imagining a partner’s sexual infidelity and other male-linked violations (for example, a partner who no longer makes an effort to look physically attractive) distressed a larger percentage of men than women. The results from two studies provided compelling evidence against a social–cognitive explanation of the sex differences and for an evolutionary psychology explanation based on men and women responding to threats to their sex-linked mating strategies.     

Antialiasing: A technique for smoothing jagged lines on a computer graphics image—an implementation on the Amiga

Images displayed on computer graphics displays often suffer from the presence of aliasing artifacts that give a jagged appearance to lines or polygon edges displayed on the screen. This paper details the problems associated with these artifacts and presents a method for drawingantialiased lines—ones in which the artifacts have been considerably reduced. The line-drawing routine is further developed to incorporategamma correction, to take into account the nonlinear relationship between the intensity of the light emission from the phosphor of the monitor and the grayscale values used to control the intensity on the screen.     

PsycWord: A Windows program for preparing clinical documentation in psychology

PsycWord is designed to guide the user through the process of rapidly producing psychological reports. Modules may be mixed to produce a variety of reports. Windows controls and standardization decrease the time needed for creating clinical reports, while flexibility is built in to encourage customization and the use of professional judgment. The program is most suitable for adult outpatients, but may be useful with other populations as well.
