The relationship between menopausal status, phase of menstrual cycle, and replacement estrogen on cognition in healthy women without dementia.

The authors examined the effect of menopausal status on several aspects of cognition in 4 groups of women (young premenopausal women, middle-aged premenopausal women, naturally postmenopausal women not using hormone therapy, and postmenopausal women using hormone replacement therapy). Participants (N = 48) completed questionnaires designed to assess psychological and physical health. The authors administered a test battery consisting of 10 neuropsychological tests to assess cognitive functioning. Using multivariate analyses of covariance with age as the covariate, the authors found a significant main effect of menopausal status on attention and complex processing abilities. Postmenopausal women using hormone replacement therapy significantly outperformed postmenopausal women not using hormone therapy on the Trail Making Test, Part B of the Halstead-Reitan (R. M. Reitan, 1958). This effect was significant even when the authors controlled for the effects of age, vocabulary levels, and education. Results are consistent with previous findings and may provide further evidence for an ameliorative effect of estrogen replacement therapy on specific cognitive functions.

Body satisfaction in college women after brief exposure to magazine images.

Female undergraduates were divided into groups based on their rated body dissatisfaction (n = 45 operationally defined as Satisfied, n = 45 as Dissatisfied). These groups were then randomly assigned to one of three magazine categories: fashion, fitness-and-health, and news. Measures of Body Satisfaction, Depression, Anxiety, Self-esteem, Fear of Fat. Eating Attitudes, and Control of Weight were taken. Significant group main effects were found on Depression, Trait Anxiety, Eating Attitudes, Fear of Fat, and Self-esteem. A significant main effect for media was found for scores on Body Satisfaction, with the fitness-and-health Dissatisfied group reporting decreased body satisfaction following magazine exposure. No interactions were found. It appears women who are dissatisfied with their bodies may be at risk for a further decrease in body satisfaction after even a 15-min. exposure to fitness and health magazines but further follow-up measures were not made.

The relationship between types of female athletic participation and female body type.

In the present study, the authors examined 53 female athletes drawn from 4 different sports and 55 female nonathletes. The athletes were divided into 2 groups: speed focused and technique focused. The nonathlete control group consisted of college women who had not participated in any varsity sports at the university level. Participants were measured on scales of body dissatisfaction, preoccupation with weight, and self-perceptions of body type and weight. Analyses revealed that (a) speed-focused athletes and technique-focused athletes did not differ significantly in their concerns about weight and body image, and (b) nonathletes expressed more dissatisfaction with their bodies than both of the athlete groups. Results are discussed with regard to associations between female sports participation and body image.

Gender differences in body size dissatisfaction among individuals with low, medium, or high levels of body focus.

The authors designed the present study to test whether women reported higher levels of body dissatisfaction than did men even when the 2 genders were matched on a measure of degree of body focus. Sixty undergraduates (30 men, 30 women) were screened on attention-to-body-shape scores and divided into high, medium, and low body-shape-focus groups. The participants also completed questionnaires that provided information on age, education, vocabulary ability, levels of depression, and body-image assessment. The groups did not differ (ps > .05) on age, education, vocabulary ability, or levels of depression. However, women in all 3 body-shape-focus categories indicated a larger discrepancy between their real vs. ideal body images (p < .01) than did the men. In the high-body-focus group, there was an 11:1ratio between women's and men's reported real-ideal body-shape discrepancies. Women showed greater body dissatisfaction than did men, even when the genders were matched on a measure of body focus.

Effects of induced emotional state on lexical processing in younger and older adults.

The authors investigated the effects of an induced emotional mood state on lexical decision task (LDT) performance in 50 young adults and 25 older adults. Participants were randomly assigned to either happy or sad mood induction conditions. An emotional mood state was induced by having the participants listen to 8 min of classical music previously rated to induce happy or sad moods. Results replicated previous studies with young adults (i.e., sad-induced individuals responded faster to sad words and happy-induced individuals responded faster to happy words) and extended this pattern to older adults. Results are discussed with regard to information processing, aging, and emotion.

Preservation of implicit memory in adult children of alcoholics.

The authors investigated implicit memory in 21 adult children of alcoholics (ACAs) and 24 control individuals (all college undergraduates) who performed a serial reaction time task (SRT) to evaluate their implicit memory performance and their formation of new associations. Each group was presented with 5 blocks of 100 trials per block in which Blocks 1-4 contained a 10-item repeating sequence; Block 5 was a pseudo-random sequence. The latency difference between Block 4 and Block 5 presumably measure implicit memory. The amount of implicit memory did not differ (in ms) between the ACAs (M = 55 ms) and the controls (M = 67 ms). Implicit memory (at least as measured by the SRT task) appears to be preserved in ACAs.

Processing fat-related information in individuals at risk for developing an eating disorder.

The authors examined the effect that being at risk for developing an eating disorder has on the lexical processing of words related to fat and words not related to fat. Individuals (n = 17) at risk for developing an eating disorder were compared with controls (n = 31) using a lexical decision task in which fat-related words (e.g., large), unrelated words (e.g., fair), neutral words (e.g., post), and pseudowords (e.g., flirp) were given. The results revealed an expected Group x Stimuli interaction for reaction times indicating that at-risk individuals were significantly faster at processing fat-related words than words unrelated to fat. The authors discuss these results within the context of how fat-related stimuli are processed in at-risk individuals and how models of information processing can aid in the interpretation and understanding of eating disorders.

False memories in individuals at risk for developing an eating disorder.

In the present study, the authors used the Roediger and McDermott paradigm (H. L. Roediger & K. B. McDermott, 1995) to examine the creation of false memories in individuals at risk for developing an eating disorder. Thirty-three controls and 34 individuals at risk for eating disorders studied 6 word lists taken from the paradigm. Three lists were food related (bread, fruit, sweet), and 3 were not food related (king, doctor, black). Both groups produced false memories (i.e., recalled or recollected words that were not presented in the lists), and controls actually produced more false memories than the at-risk individuals produced in the recall of the food-related items. Groups did not differ in their recall of items not related to food.

Lack of association between negative priming and Necker Cube reversals.

50 undergraduates were tested on two tasks presented in a counterbalanced fashion: their ability to inhibit irrelevant information measured on a negative priming task involving letter case information and on the number of Necker Cube reversals produced in a specific time period. Since number of reversals presumably reflects a person's ability to see various interpretations of the Necker Cube, this assumes that multiple interpretations are available to a subject and no one interpretation dominates over another. If true, then more reversals could indicate an ability to inhibit irrelevant information. That is, observing one reversal at the expense of another reversal indicates a subject can adequately inhibit these various interpretations successfully, with more reversals indicating a higher ability to inhibit information successfully. Although it was predicted that negative priming performance would be related to the number of Necker Cube reversals, this was not the case (r = -.07).

Orthographic neighborhood size, number of word meanings, and number of higher frequency neighbors.

The present lexical decision task experiment examined orthographic (large, medium, small), number-of-meanings (ambiguous, unambiguous), and number of higher frequency neighbors (few, many), factors that have to date not been studied simultaneously. For both mean reaction time and percentage error, the critical three-way interaction between these factors was significant. Breakdown of this interaction revealed that the ambiguity effect (unambiguous-ambiguous) decreased as neighborhood size increased, but only when there were many higher frequency neighbors in the neighborhood. These results appear inconsistent with serial search models but are understandable within the context of interactive-activation models of word recognition.

Effects of orientation on Rey complex figure performance.

An experiment was performed that examined the impact of stimulus orientation on performance on the Rey complex figure. A total of 48 undergraduates (24 men, 24 women) were randomly assigned to one of four Rey figure orientation groups (0 degrees, 90 degrees, 180 degrees, and 270 degrees ). Participants followed standard procedures for the Rey figure, initially copying it in whatever orientation group they were assigned to. Next, all participants performed a 15-20 min lexical decision experiment, used as a filler task. Finally, and unbeknownest to them, participants were asked to recall as much of the figure as they could. As expected, results revealed a main effect of Task (F = 83.92, p < .01), in which copy performance was superior to recall performance. However, the main effect for orientation was not significant, nor did orientation interact with task (Fs < .68, ps > .57). The results are important from an applied setting, especially if testing conditions are less than optimal and a fixed stimulus position is not possible (e.g., testing at the bedside).

Visual degradation in Boston Naming Test performance.

The 60 pictures of the Boston Naming Test were degraded via a mask to be either "easy," "medium", or "hard" to process visually. The visual mask was created by cutting a 2-in. x 2-in. square from a security mailing envelope and progressively reducing the size 25% on a copy machine. Three groups of 50 undergraduates each were randomly assigned to one of these three degradation conditions, and the number of correct identifications made was measured. We expected that as degradation increased (from easy to medium to hard), Boston Naming Test performance would decrease. A one-way analysis of variance indicated that group scores differed. With "easy" degradation more pictures were identified in comparison with performance in the "hard" degradation condition, but no other differences were significant. Results were discussed from the perspective of how unknown situational variables may affect performance on psychological tests.
