In‐group reassurance in a pain setting produces lower levels of physiological arousal: direct support for a self‐categorization analysis of social influence

A large body of research demonstrates a strong social component to people's pain experiences and pain‐related behaviours. We investigate this by examining the impact of social‐influence processes on laboratory‐induced pain responses by manipulating the social‐categorical relationship between the person experiencing pain and another who offers reassurance. We show that physiological arousal associated with laboratory‐induced pain is significantly lower in normal, healthy participants following reassurance about the pain‐inducing activity when that reassurance comes from an in‐group member in contrast to reassurance from an out‐group member and a no reassurance control. These data are consistent with predictions derived from self‐categorization theory, providing convincing empirical support of its analysis of social influence using a non‐reactive measure. These data also represent a clear advance within the pain literature by identifying a possible common process to the social‐psychological component of pain responses.

Predicting Affective Responses to Unexpected Outcomes

In decisions under uncertainty, decision makers confront two uncertainties: the uncertain linkage between actions and outcomes and the uncertain linkage between these outcomes and his or her affective responses to them. The two studies reported here examine affective responses to expected and unexpected outcomes in various settings. In Study 1, a scenario-based laboratory experiment (N = 149), we examined subjects' predicted responses to a range of outcomes, as a function of how surprising the outcome was. Study 2, a field study (N = 127), involved the expectations of bowlers about their scores in an upcoming game and about their responses to various outcomes at, above, and below expectations. We also measured actual affective reactions after the bowlers had completed their games. Findings suggest that subjects both expect and experience a loss-averse, expectation-based value function broadly of the Prospect Theory type. They also anticipate, and experience, an amplifying effect of outcome surprise, though they underestimate its size. We argue that such underestimation, together with overtight prediction ranges, may expose subjects to much larger affective variation with outcome variability than they anticipate.     

Reliability and validity of the Multiple Affect Adjective Check List - Revised

A recent factor analysis of the Multiple Affect Adjective Check List (MAACL) changed the Anxiety, Depression, and Hostility scales from bipolar to unipolar scales and added two new scales: Positive Affect and Sensation Seeking. Internal reliability of the MAACL-R scales, computed for normal and patient samples, was adequate for state and trait forms except for Sensation Seeking. Test-retest reliability in college students was higher for the trait form with retest intervals of from 2 to 8 weeks than for the state form with retest intervals of from 2 to 5 days. The pattern of correlations among self-, peer, and counselor ratings and the MAACL-R scales for normal and patient samples indicates improved discriminant validity and equally good convergent validity as the old scales. The use of standard scores that are indexed to the number of items checked reduced scale intercorrelations by controlling the acquiescence set.The financial support of the Weldon Springs Endowment Fund, University of Missouri at Kansas City, toward the completion of this research project is gratefully acknowledged.     

Out of the laboratory and into the community. 26 years of applied behavior analysis at the Juniper Gardens Children's Project.

Application of Skinner's principles to socially significant human behavior had been well articulated by 1968 (Baer, Wolf, & Risley, 1968). Applications of these principles by Baer, Wolf, Risley, Hall, Hart, Christophersen, and their colleagues were in evidence as early as 1964 in the homes, schools, and clinics of inner-city Kansas City, Kansas, at the Juniper Gardens Housing Project. The work continues relatively uninterrupted, having contributed extensively to the literature of applied behavior analysis and the lives of community residents. This article describes the project and illustrates how applied behavioral research was initiated and extended, how the work addressed general concerns in psychology, and how it continues to address contemporary concerns within the community.     

THE CLASSWIDE PEER TUTORING PROGRAM: IMPLEMENTATION FACTORS MODERATING STUDENTS' ACHIEVEMENT

We conducted a study designed to assess implementation of the classwide peer tutoring program and the relationship between implementation variation and student outcome. A clinical replication design was used. Five volunteer elementary teachers were trained to implement the program; their implementation was monitored for 19 consecutive weeks during 1 school year. Overall, the results indicated that specific variations in program implementation were associated with students' responses to treatment. It was also demonstrated that different teachers' applications of the program produced differential levels of student outcome. Implementation factors related to lower spelling achievement were (a) reduced opportunities to receive program sessions, (b) reduced probabilities of students' participation in program opportunities, (c) too many students assigned unchallenging spelling words, and (d) reduced rates of daily point earning reflecting lower levels of spelling practice during tutoring sessions. The implications of these findings and methods of preventing these implementation problems are discussed in the context of quality assurance and social validity.     

The California Family Health Project: IV. Family structure/organization and adult health.

This research explores the relationships between each of four "domains" of family life and the health of husbands and wives in a community-based sample of 225 families. In this article we report the association between Family Structure/Organization and adult Health. This family domain refers to the architecture of the family or the structural frame of roles and rules within which the family operates. Interrelationships among 13 self-reported, family Structure/Organization scales are described, using principle components analysis (PCA) and multidimensional scaling analysis (MDS). Derived, joint-spouse or couple Structure/Organization variables also were created using inter-battery factor analysis. The PCA yielded a poor solution, whereas the MDS yielded a good two-dimensional solution, which roughly displayed the scales in a circular pattern for both husbands and wives. The analyses indicated that no single dimension or set of separate subdimensions adequately described the Structure/Organization variables. All 13 scales than were associated with a battery of 14 adult health scales for husbands and wives separately, using canonical correlation. Different aspects of family Structure/Organization were correlated with health for husbands and wives: Organized Cohesiveness, Sex Role Traditionalism, Role Flexibility and Shared Roles for husbands; and Organized Cohesiveness and Differentiated Sharing for wives. Different patterns of health scores also emerged by gender, with behavioral indicators, such as Smoking and Drinking, more salient for husbands, and mood indicators, such as Anxiety and Depression, more salient for wives.     

The California Family Health Project: II. Family world view and adult health.

This article explores the pattern of relationships between family World View and adult Health in a community-based sample of 225 families. Family World View refers to the beliefs, appraisals, and values that define a family's orientation to the world. The interrelationships among eight self-reported family World View variables are described, using principal components analyses (PCA) and multidimensional scaling analyses (MDS). Derived, joint-spouse World Views also are examined using inter-battery factor analysis. The World View variables then are analyzed as a set with 14 self-reported health variables for husbands and wives separately, using canonical correlation. The PCAs for family World View yielded poor solutions for both husbands and wives. The MDS displayed the eight variables in a circular pattern for husbands and for wives, indicating the absence of a single broad dimension, or subgroupings of separate dimensions, that could be used to "describe" the domain. In the canonical analyses, family World View was a strong correlate of Health, with approximately 50% of the variance accounted for by the respective canonical variates. For husbands, what we called Family Coherence, Family Religiousness, Family Life Engagement, and Family Optimism, were correlated with Health. For wives, Family Coherence, Family Religiousness, and Family Optimism, were correlated with Health. Different patterns of health scores emerged by gender, with behavioral indicators, such as Smoking and Drinking, more salient for husbands, and mood indicators, such as Anxiety and Depression, more salient for wives.     

The California Family Health Project: III. Family emotion management and adult health.

This article explores the broad patterning of interrelationships between family Emotion Management and adult Health in a community-based sample of 225 families. Emotion Management refers to how emotion is expressed, acknowledged, and managed by the marital partners. Fifteen reliable-observer ratings of husband-wife behavior were made during each of three 10-minute Emotion Management Interaction Tasks (EMITs). Each of the three tasks "pulled" for the expression of a different emotional theme: loss, intimacy, or conflict. A principle components analysis of the 15 ratings yielded a poor solution. A nonmetric, multidimensional scaling analysis described a two-dimensional, bipolar display with ordering among the variables in each of two wings. One dimension reflected positive versus negative Emotion Management characteristics, and the second reflected active and overt versus passive or covert emotional expression. The pattern of relationships among the couple ratings was similar for each of the three tasks. Using canonical correlation, the couple ratings demonstrated significant associations with 14 adult Health scores for both husbands and wives for the intimacy and conflict tasks, but not for the loss task. Specific gender patterns also emerged. In general, couple overt emotional aversiveness was negatively associated with husbands' health, and couple emotional avoidance/distance was negatively associated with wives' health.     

The effects of social support on children's eyewitness testimony

Child witnesses often give only short accounts of witnessed events. Part of the reason for this failing centres on the stress present during an interview. The most obvious means of reducing stress in children, through the provision of social support, has typically been neglected in eyewitness research, presumably because of fears over children's excessive suggestibility. Social support is also believed to inhibit children during interviews. However, these fears appear to stem more from general suspicions about children's competencies rather than empirical findings. Studies are described which show that child witnesses express a strong desire for social support, and that support may be provided in a number of different ways, from peers as well as adults. It is argued that social support is one of the most unfairly neglected issues in eyewitness research, and the minimal evidence available suggests that allowing support may have a facilitative effect on task performance, including free-recall memory.
