Peter McHugh and Analysis: The One and the Many, the Universal and the Particular, the Whole and the Part

This paper takes the passing of Peter McHugh as an occasion to examine the intellectual development of his work. The paper is mainly focused on the product of his collaboration with his colleague and friend, Alan Blum. As such, it addresses the tradition of social inquiry, Analysis, which they cofounded. It traces the influence of Harold Garfinkel’s Ethnomethodology on McHugh and on the beginning of Analysis. The collaboration with Blum is examined through a variety of coauthored works but most especially in the two books On the Beginning of Social Inquiry (1974) and Self Reflection in the Arts and Sciences (1984). It also examines the relation of his independent writing before 1974, and since 1984 to the expression of the tradition of inquiry as exemplified in those two texts. The paper builds on some interview material with Peter McHugh and reflects on the influence of Peter the teacher as well as the theorist McHugh. Most especially, through its engagement with this material, it seeks to exemplify the dialectic and living nature of the program called Analysis.     

Collective estimation: Accuracy,expertise, and extroversion as sources of intra-group influence

Although estimations typically possess correct answers, these answers may be difficult to demonstrate to others. However, providing external information may increase their demonstrability. In this experiment, individuals (N = 60) and 6-person groups (N = 360) generated estimations with or without frames of reference. We hypothesized that estimations involving frames of reference would be best fit by models predicting intra-group influence based on the accuracy of alternatives or of members in general. Conversely, we hypothesized that estimations not involving frames of reference would be best fit by models predicting influence based on member extroversion or proposal centrality. Results indicate that groups outperformed individuals and that estimations generated in the presence of frames of reference were superior to those generated in their absence. Accuracy and expertise schemes provided the best fit when frames of reference were provided, whereas an extroversion scheme provided the best fit when they were not.     

A prospective investigation of suicidal ideation in college students: a test of a model

In order to test the predictive validity of a stress--vulnerability model of suicide ideation and behavior, a longitudinal study was conducted with college undergraduates. Based on previous research (Bonner & Rich, 1987; Rich & Bonner, 1987a), measures of social/emotional alienation, adaptive resources for living, and cognitive rigidity were taken at the beginning of the semester and combined to develop a vulnerability score. Then, at midterm, measures of midterm stress and cumulative negative life stress were obtained from the same subjects. It was hypothesized that the vulnerability factor would interact with midterm and negative life stress to predict suicide ideation. Instead of an interactive model, a linear, compensatory model of suicide ideation was found. The combination of alienation, deficient adaptive resources, and life stress best predicted ideation scores. Implications for research and theory are noted.     

Motivated self-stereotyping: heightened assimilation and differentiation needs result in increased levels of positive and negative self-stereotyping

This research was conducted to explore the impact of assimilation and differentiation needs on content-specific self-stereotyping. According to optimal distinctiveness theory (M. B. Brewer, 1991), social identities serve the function of satisfying individuals' need for assimilation (in-group inclusion) and their need for differentiation (distinctiveness from others). It was proposed that one of the ways optimal social identities are maintained is through self-stereotyping. In 3 studies, the needs for assimilation and differentiation were experimentally manipulated, and support was found for increased self-stereotyping in response to heightened need arousal across both self-report and behavioral measures and across different social groups. Results also demonstrated that only those participants who were highly identified with their in-group were willing to engage in negative self-stereotyping.     

Spirituality and Cognition: Does Spirituality Influence What We Attend to and Remember?

This study investigated how spirituality as a positive life theme might be related to one’s unique style of cognitive processing. Study participants included 80 individuals; 40 older adults and 40 younger adults. Word recall and recognition tasks assessed memory for positive, negative, neutral, and religious words. Results indicated that spirituality does not appear to be related to cognitive bias, but that words with either positive, negative, neutral, or religious connotations are recalled and recognized at different rates.     

Modeling collective choice: decision‐making on complex intellective tasks

Three studies examined group problem‐solving on complex intellective tasks. In Study 1, a decision model proposed by Laughlin and Hollingshead ( 1995 ) provided the best fit to actual group choices. This study also compared three‐person group versus individual performance with time constrained and number of problems unconstrained, with individuals solving non‐significantly more problems and groups obtaining significantly superior trials‐to‐solution scores. In Study 2, one member of each group was given additional information on how to perform the task and member extroversion was measured. Neither factor significantly impacted the decision‐making process. In Study 3, task expertise was assessed prior to the group interaction. Results indicate that group members were twice as likely to adopt an option proposed by an expert compared to other group members. Together these studies demonstrate that group problem solving is governed jointly by qualities of the task and qualities of the group members. Copyright © 2006 John Wiley & Sons, Ltd.     

Informational intra‐group influence: the effects of time pressure and group size

The judgments of groups have immense impact on our daily lives. This paper theorizes that three families of intra‐group influence affect the collective estimation process. These different forms of influence map to different levels of task demonstrability, or the extent to which correct answers are transparent to problem‐solvers. When demonstrability is low, group estimates are disproportionately influenced by proposals closer to the intra‐group mean (centrality). When demonstrability is high and groups are small, group decisions are disproportionately influenced by proposals closer to the correct answer (accuracy). Finally, when demonstrability is high and groups are larger, group decisions are disproportionately influenced by proposals offered by generally more accurate individuals across a set of judgments (expertise). Three laboratory studies support our predictions with regard to informational influence in cooperative groups. Copyright © 2006 John Wiley & Sons, Ltd.     

Sex education attitudes and outcomes among North American women

Attitudes and outcomes of sex education received by North American women are examined via an Internet survey (N = 1,400). Mean age was 19.5, with 24% reporting one or more unplanned pregnancies. Women were more satisfied with sex education from informal sources than from parents, schools, and physicians. Those receiving sex education from parents or schools reported fewer pregnancies and abortions. In school, women receiving a combination of contraceptive and abstinence education and those receiving primarily abstinence education were least likely to experience unplanned pregnancy. Religious identification was significantly related to unplanned pregnancy and type of sex education received from parents. These factors seem to play a significant role in reducing unplanned pregnancy and abortion.
