Effects of spacing and embellishment on memory for the main points of a text

An advantage has been found for acquiring textbook knowledge by studying textbook summaries rather than reading the original prose (Reder & Anderson, 1980). Three studies are presented that help to establish the cause of the summary advantage. One possible cause is that reading summaries allows the subject to reread the main points at spaced intervals, and spaced practice is superior to massed practice. A second possible cause is that the presence of details distracts the subject’s attention away from the critical ideas that should be attended to. In Reder and Anderson (1980), these two factors were confounded, but they are unconfounded in the present studies. The results indicate that both possible causes, spaced practice and the absence of details, have significant, independent, and positive effects on retention of the central ideas of a passage.     

Looking beyond gender: The effects of racial differences on tokenism perceptions of women

This study looks beyond gender to explore the impact of the social status of race and of token difference defined by race. In a 2 × 4 design, 53 African American women and 76 white women undergraduates rated a woman target, of the same race as themselves, who was described as being of the same race and gender as the dominant members of her work group or as a token defined by her gender alone, race alone, or both her race and gender. White women tokens were perceived to experience better social relations, more supportive colleagues, and lower stress than African American targets. Across African American and white raters/targets, token representation, defined by any ascribed status, was associated with expected negative tokenism outcomes relative to those projected for dominants. The omnirelevance of race toward understanding tokenism processes is discussed.We wish to thank Marchell Bass, Paulina Beres, Darya Burns, Roy Carrera, Nicole Cassie, Comilita Jackson, Susan Mathews, Pamela Ramsey, Catina Scott, and Aretha Strickland for their invaluable help with data collection and entry. These findings were presented at the meeting of the Midwestern Psychological Association in May 1995 in Chicago.     

Working Memory: Activation Limitations on Retrieval

Two experiments which require subjects to hold a digit span while solving an equation and then recall the digit span are performed. The size of the memory span and the complexity of the equation are manipulated as well as whether the subject is required to substitute items from the digit span for constants in the equation. As either task (digit span recall or equation solving) gets more complex there are performance decrements (accuracy or latency) not only in that task but also in the other task. It is also shown that the majority of the errors are misretrievals. These results are consistent with the proposal that working memory load has its impact on retrieval from memory. These results are fit by the ACT-R theory (Anderson, 1993) which assumes that there is a limit on source activation and that this activation has to be divided between the two tasks. As either task increases in complexity there is less activation for retrieval of information from declarative memory. Subjects’ misretrievals of associatively related information could be predicted by assuming a partial matching process in ACT-R.     

Gender Differences in Supervisors’ Use of Performance Feedback1

This study examined whether male and female supervisors differed in their delivery of performance feedback to subordinates. Male and female subjects supervised 2 confederate subordinates whose performance was stable and either above or below average. Supervisors regularly checked each subordinate's performance and could deliver one of several feedback messages. A MANOVA was performed on frequency of specific negative, general negative, specific positive, general positive, and neutral feedback messages, followed by step down analyses to isolate which dependent variables contributed uniquely. Male and female supervisors were distinguished by their use of specific negative feedback. Males were more likely to provide such messages to poorly performing subordinates, a result consistent with suggestions that males are characterized by a more directive leadership style.

Estimating rates of chronic fatigue syndrome from a community-based sample: A pilot study

Most of the Chronic Fatigue Syndrome (CFS) epidemiological studies have relied on physicians who refer patients having at least 6 months of chronic fatigue and other symptoms. However, there are a number of potential problems when using this method to derive prevalence statistics. For example, some individuals with CFS might not have the economic resources to access medical care. Other individuals with CFS might be reluctant to use medical personnel, particularly if they have encountered physicians skeptical of the authenticity of their illness. In addition, physicians that are skeptical of the existence of CFS might not identify cases. In the present pilot study, a random community sample (N=1,031) was interviewed by telephone in order to identify and comprehensively evaluate individuals with symptoms of CFS and those who self-report having CFS. Different definitions of CFS were employed, and higher rates (0.2%) of CFS were found than in previous studies. Methodological benefits in using more rigorous epidemiological methods when estimating CFS prevalence rates are discussed. The authors appreciate the generous financial support of the CFIDS Association and Minnan, Inc. We also are grateful for many helpful suggestions provided by Judith A. Richman, William McCready, Wendell Richmond, and Stephen E. Goldston.
