Perception,meaning, and mind

Earlier versions of this paper were read in the Philosophy department at the University of Helsinki, in the Institute for Advanced Studies in the Humanities at the University of Edinburgh, at Vanderbilt University, at the Indiana Philosophical Association, and at the Institute for Logic and Cognitive Science at the University of Houston. I am grateful for very helpful comments on each of these occasions, and I am especially appreciative to John Haugeland, Mark Johnson, and George McClure for their comments and suggestions. Thanks, too, to Robert Solomon who urged me to amplify my claims about perceptual meaning.     

A psychometric study of the Family Adaptability and Cohesion Evaluation Scales

The Family Adaptability and Cohesion Evaluation Scales (FACES), a measure of family functioning, contains three scales: cohesion, adaptability, and social desirability. These were slightly modified (FACES- R) on the basis of pilot data and were administered to 42 clinic families (families seeking or receiving psychological services) and 206 nonclinic families. Support for the scales was found in high coefficient alpha reliabilities and similarity of the sample means and standard deviations to those of the standardization sample. However, there was little agreement among family members' scale scores. Therapists' ratings of cohesion and adaptability did not correlate with scale scores among clinic families. There was no difference between clinic and nonclinic samples on the cohesion or adaptability scales, although the social desirability scale did discriminate between groups. Factor analysis suggested that cohesion, adaptability, and social desirability cannot be clearly differentiated using this measure.This work was supported by the American Association of University Women and by Grant R01HD13820 from the National Institute of Child Health and Human Development.     

Women's body satisfaction at midlife and lifetime body size: a prospective study.

The relationship between past body size and current body dissatisfaction among 933 middle-aged women from a prospective birth cohort study was examined. Women provided self-report data on weight esteem at age 54. Height and weight data were collected at ages 7, 11, 15, 20, 26, 36, 43, and 54. Data on reproductive variables were also collected prospectively. Hierarchical linear modeling and multiple regression analyses were used. Women who were dissatisfied at midlife were heavier at age 7 and showed a more rapid increase in body mass index with age. A late menarche, being postmenopausal, and having started hormone replacement therapy before menopause were associated with less dissatisfaction. Attention to these factors across the life span is necessary to understand body dissatisfaction in women at midlife.     

Hypnotic enhancement of cognitive-behavioral interventions for pain: an analogue treatment study.

Recent meta-analyses have shown that adding hypnosis enhances the effectiveness of cognitive-behavioral psychotherapy. This hypnotic enhancement effect was evaluated in the analogue treatment of pain. Individuals scoring in the high (n = 135) and low (n = 150) ranges of hypnotic suggestibility were randomly assigned to 1 of 6 conditions: Stress Inoculation Training, the same treatment provided hypnotically, nonhypnotic analgesia suggestions, hypnotic analgesia suggestions, a hypnotic induction treatment, or a control condition. The 5 analogue treatments reduced experimental pain more than the control condition, but were not different from one another. Under circumstances optimized to detect an enhancement effect, neither Stress Inoculation Training nor analgesia suggestions produced more relief when delivered in a hypnotic context than identical treatments provided nonhypnotically.     

Group discussion and first advocacy effects in computer-mediated and face-to-face decision making groups

This study examines whether the first group member to advocate a position in the group publically has disproportionate influence on the group decision, and whether group discussion by computer mail or face-to-face determines the extent of the first advocate's influence. Possible explanations of first advocacy influence were tested in an experiment that allowed simultaneous observation of three independent variables: (1) assignment of first advocate (self-selected/randomly assigned), (2) early discussion before advocacy (discussion/no discussion), and (3) mode of communication (face-to-face/electronic mail). It was assumed that a first advocate effect exists if the group choice is closer to the first advocates' stated positions than to the group's average pregroup preferences. An “influence” hypothesis predicts that first advocates who self-select will be closer to the group decision than average pregroup preferences because these are first advocates most likely to persuade other members of the group. A “listening” hypothesis predicts that first advocates who hear an early group discussion will be closer to the group decision than average pregroup preferences because these first advocates are able to anticipate the group decision as a result of listening to what is communicated in group discussion. The results indicated strong support for the “listening” hypothesis. When groups held early discussions before someone advocated a position, the first advocate effect was observed; when groups did not hold early discussions but began their task by having someone advocate a position, there was no first advocate effect. The data suggest that the content and tone of electronic group discussions was qualitatively different from face-to-face group discussions, but the process of group decision making in both conditions was about the same. The implications of these results for group discussion and computer-mediated group decision making in organizations are discussed.     

The Caregivers of Stroke Patients: An Investigation of Factors Associated with Depression

Caregivers of the elderly and infirm are often under more stress and report lower life satisfaction than matched groups of noncaregivers. Forty caregivers of stroke patients (usually a spouse) were interviewed an average of 9 months poststroke to determine the factors associated with poorer caregiver adjustment. Four classes of variables were expected to be related to depression in caregivers: level of functioning of the patient, caregiver perceptions of increased work and burden due to the stroke, the quality of the patient-caregiver relationship, and caregivers' interpretations of their situation. Background characteristics were also measured. As predicted, variables in each class were significantly related to depression. Multiple regression analysis showed three significant independent predictors of caregiver depression. Caregivers are more depressed if the patient is more physically impaired, if caregivers report disharmony in the family, and if they have lesser perceptions of hope Ways to apply these findings to the development of interventions to ameliorate caregiver depression are discussed.
