STM Experimenter: Using HyperCard and MacRecorder in short-term memory experiments

We describe a Macintosh program for the presentation of spoken word lists in short-term memory (STM) experiments. The program was developed with the use of HyperCard and MacRecorder. Parameters such as rate of item presentation, number of items per trial, and number of trials per block may be adjusted by the experimenter. The program features high-quality digitized sound, trial-to-trial word list randomization, and data logging. Computer-based experimentation offers several advantages over traditional approaches that involve tape recordings or lists read aloud by the experimenter. Methodological improvements afforded by computer-controlled item administration are discussed.     

Self-reports of depression and state-trait anxiety: evidence for differential assessment.

Several researchers have found anxiety and depression to be indistinguishable in nonclinical samples and have suggested that both constructs may be components of a general psychological distress process. Another possibility is that overlap is due to the psychometric limitations of scales used. A series of exploratory factor analyses were conducted in a nonclinical sample (N = 605) using the Beck Depression Inventory (BDI; Beck, 1978), the State-Trait Anxiety Inventory (STAI; Spielberger, 1983), and the Endler Multidimensional Anxiety Scales (EMAS; Endler, Edwards, & Vitelli, 1991). Both state and trait anxiety and depression could be differentiated with the BDI and the EMAS but not with the STAI. Some theoretical models of negative affectivity or general psychopathology may be premature.     

A dental roll technique for the measurement of salivary activity

A discussion of the development of a method for the analysis of salivary activity is presented. Results gained using this new method are compared with those obtained using a whole-mouth spitting technique. The application of the new method in real-world situations is indicated. Norms are presented for measures of salivary flow, pH, and salivary ion concentration based on experimental studies of a female working population.     

Codes of medical ethics and the exportation of less-than-standard care

Recently a number of AIDS/AZT research studies, carried out by U.S. universities, have come under intense ethical scrutiny. In these studies, control groups of HIV-positive pregnant women were being given a placebo rather than AZT. Such research protocols would be illegal if practiced in the U.S. I examine a number of lamentable ethical lapses in the studies, and conclude that at least some of these ethical problems are traceable to a troubling contradiction between differing international codes of ethics. In a word, some international codes mandate that all research subjects (including control groups) receive the best standard of care available in the country sponsoring the research, while others suggest that providing only a "local" standard of care is ethically appropriate. I argue that these two ethical mandates cannot both be satisfied, and that host country populations will remain subject to exploitation unless this contradiction is resolved.     

Effects of telic dominance and metamotivational state on squash task performance

Measures of telic dominance and metamotivational state were obtained from 40 volunteer males grouped on the basis of their playing ability, before and after the performance of squash tasks. Utilising a mixed-blocks design, which controlled for order of task, subjects were required to perform two squash tasks of differing difficulty. Significant differences between groups on performance were obtained, confirming the ability classification, but no significant differences in telic dominance were found. Significant increases in mood response in the telic direction were found on pre- and posttask scores. A significant decrease in discrepancy scores (preferred arousal minus felt arousal) obtained pre- and posttask was noted, together with a significant interaction between skill level and in arousal discrepancy pre- and posttask. In all cases trends were least for the most skilled group.     

Acute effects of aerobic exercise on mood

Thirty-two female students participated in a single-session experiment during which they carried out two 8-min trials of high-intensity exercise and two 8-min trials of low-intensity exercise. One high- and one low-exercise trial were accompanied by music; the other two trials were accompanied by metronome. Mood was assessed with a modification of the Profile of Mood States before and immediately after each trial. The purpose of the experiment was disguised to reduce the influence of subject expectations on mood responses. Participants were divided into fit and unfit groups based on heart rate responses during high-exercise trials. Overall, high-intensity exercise led to increases in tension/anxiety and fatigue, whereas positive mood changes (vigor and exhilaration) were seen following low-intensity exercise only. No group differences in mood responses were observed. Explanations of these results are considered in light of other literature concerning the acute effects of exercise on mood.     

Evidence that secretory IgA antibody is associated with daily mood

In this study, we examined the secretory immune system, the body's first line of defense against invading organisms, and its relation to daily fluctuations of mood. Specifically, secretory immunoglobulin A (sIgA) was studied. Unlike other psychoimmunity studies that examined all sIgA protein regardless of specificity to invading organisms, ours examined an antigen-specific sIgA response to the oral administration of a harmless protein (rabbit albumin) and monitored the antibody produced in response to the protein. Dental students recorded their daily mood thrice weekly for 8 1/3 weeks, and parotid saliva was obtained from subjects during these contacts. Using a within-subjects analyses strategy, we found that antibody response was lower on days with high negative mood relative to days with lower negative mood, and conversely, sIgA antibody response was higher on days with high positive mood relative to days with lower positive mood. Results from total sIgA protein were in the opposite direction, although not significantly so. These results extend our knowledge of immunological changes and mood, and they suggest that minor life events' role in health may be mediated by the secretory immune system.     

Resume evaluations and cosmetics use: When more is not better

Physical appearance is an integral component of self-presentation in all social situations, including that of applying for a job. This project investigated the relationship between employment evaluations of women and one aspect of their appearance under the individual's control—the use of varying degrees of cosmetics. Cosmetics use was found to be positively correlated with perceived attractiveness, femininity, and sexiness. Based on resume evaluations, however, cosmetics use had a negative effect on the expected performance of female applicants for a gender-typed (secretary) position, but no effect on the expected performance of female applicants for a nongender-typed (accountant) position. Makeup thus appears to strengthen sex role stereotypes associated with traditionally feminine jobs.We gratefully acknowledge the assistance of Merle Norman Cosmetics and John B.
