Note on functional measurement and data analysis

The guiding idea of functional measurement is that measurement theory and substantive theory form an organic unity. Psychological scales are inherent in the statement of quantitative psychological laws, and these laws themselves form the base and frame for psychological measurement. Valid scales thus depend on empirically valid laws. But establishing empirical validity of any law requires appropriate data analysis. Several statistical problems are discussed with respect to simple algebraic laws. To illustrate the necessity for proper tests of goodness of fit for algebraic models, five sets of experimental data are reanalyzed. In each case, the factorial plot and the analysis of variance showed that the data were nonadditive. Nevertheless, an additive model was fit to the data. The correlations between the data and the predictions from the additive model were extremely high, ranging from .964 to .9997. The corresponding observed-predicted scatterplots also gave little sign of the deviations from additivity. These correlation-scatterplot analyses conceal and obscure what the factorial plot and the analysis of variance reveal and make clear. Other topics discussed are accepting and rejecting the null hypothesis, the use of nonmetric smoothing for parameter estimation, and problems of stimulus-response-model generality. An extension of functional measurement is suggested for a practicable error theory for nonmetric analysis.     

Units of word recognition: Evidence for the use of multiple units

The present experiments were concerned with subsyllabic units in word recognition. The studies employed a same-different RT task. A one-syllable word and a probe were presented simultaneously, and subjects responded “same” if the probe was an integral subset of the word (BLAST:BL), and “different” otherwise (BLAST:BC). Probes included single letters (BLAST:L), doublets (BLAST:LA), triplets (BLAST:LAS), and the whole word (BLAST: BLAST). The first experiment suggested that a variety of spelling patterns, as well as the whole word, served as units of processing. In particular, initial consonant clusters were processed as quickly as single letters, and only slightly faster than the whole words. Consonant strings were used in the second experiment, which demonstrated spelling pattern effects with permissible strings (BLGST:BL) as compared to nonpermissable strings (BXJPK:BX). A third experiment demonstrated that the particular effective units depend on task demands.     

Malleability of social impressions of hyperactive children

The role of adults' social cognitions in mediating judgments of hyperactive children's medicationrelated behavior change was explored. Two hundred eightyeight undergraduates observed two videotaped excerpts of a hyperactive target boy playing a group game with two peers. Each target was taking either methylphenidate (0.6 mg/kg) during both excerpts, placebo during both excerpts, methylphenidate first followed by placebo, or placebo first followed by methylphenidate. Adults' cumulative social evaluations of the child were assessed after they viewed both video segments. Results indicated that observers combined their perceptions of the two behavior samples into composite impressions using an equalweight averaging algorithm. Even for children whose behavior improved, adults' ratings of undercontrolled behaviors continued to meet or, in some cases exceed, research cutoff scores used to identify hyperactive children. The findings suggest that the actual behaviors of children with attentiondeficit hyperactivity disorder (ADHD) play a more influential role in shaping interpersonal impressions than do perceiver socialcognitive processes such as primacy, recency, or integration biases.This project was supported in part by a UC Regents' Dissertation fellowship to Douglas A. Granger while at the University of California at Irvine. We acknowledge Tom Crawford and Karen Rook for their helpful comments at formative stages of this project, and support from the UCLA Fernald Child Study Center and Program in Psychoneuroimmunology.

A preliminary report of this study was presented at the 1991 meeting of the Society for Research in Child Development, Seattle, WA.     

Differences in Supervisory Needs and Expectations by Trainee Experience,Cognitive Style,and Program Membership

In this study the authors examined relationships between trainees' cognitive style, program membership, amount of practicum experience, and needs and expectations for supervision. Participants were 57 trainees in three graduate programs at a midwestern university. All respondents completed the Myers-Briggs Type Indicator (MBTI; Myers & McCaulley, 1985), the trainee version of the Supervisor Perception Form (SPF-T; Heppner & Roehlke, 1984), and the Supervisory Needs subtest of the Counselor Development Questionnaire (CDQ-SN; Reising & Daniels, 1983). Results suggested that trainees' expectations and needs regarding the supervisory experience differed by amount of practicum experience, cognitive style, and program membership. Differences due to amount of experience were more prevalent than were those due to cognitive style or to program membership.     

Small and unfilled psychotherapy groups: Understanding and using them effectively

Many open-ended psychotherapy groups have fewer than five members, and fewer than the number the therapist considers necessary for the group to be filled. This paper discusses the rationale for starting such groups and the special dynamics of running them. It then suggests strategies for the therapist to use in maximizing their therapeutic effectiveness. Suggestions are made for further research into the demographic and dynamic aspects of such groups.     

The rise in demand for counselling

Explanations for the rise in demand for counselling are discussed. These include dissatisfaction with clinical psychology, the loss of social and personal supports, New Age aspirations for personal development, and insuficient numbers of clinical psychologists. Evidence is presented against the views that there has been a recent loss of social or personal supports, and that personal-development aspirations through unorthodox routes are a new phenomenon. The apparent rise in demand for counselling is explained rather as a rise in demand for counselling training, by would-be practitioners. This demand in turn is fuelled by developments in public-sector employent, leading employees to seek extra qualifications to enhance their job security. Nevertheless, the relatively weak appeal of clinical psychology, together with its low public visibility and its weak licensing power, encourage the continual emergence of alternative therapies.     

Type A behavior and processing of social conflict information

Research suggests that the Type A pattern as assessed by the Jenkins Activity Survey (JAS) involves a number of stress-engendering cognitive/social responses. To identify potential responses responsible for social stress, the study tested the relationship between JAS Type A behavior and several cognitive/social variables relevant to assertiveness situations. Male undergraduates completed two measures of cognitive complexity and rated the reasonableness of another's request. Also, subjects were evaluated for positive content (i.e., consideration of the other) in role-played assertion responses. Type A behavior correlated with lower differentiation when sorting aspects of an assertion situation, lower integrative complexity when thinking about conflict topics, and less inclusion of consideration content.     

Hostility patterns and health implications: correlates of Cook-Medley Hostility Scale scores in a national survey

Correlated Cook-Medley Hostility Scale (Ho) scores with sociodemographic variables in a national survey of 2,536 adults. Multiple regression models revealed that Ho scores were associated with race (p less than .0001), years of education (p less than .001), sex (p less than .001), occupation (p = .0002), and income (p = .0025). Higher scores were found in non-Whites, men, and those of lower socioeconomic status. There was a Race x Income interaction (p less than .005), such that the greatest Ho score differences between the races occurred among those with the lowest incomes. Age was related to Ho scores in a curvilinear fashion: higher scores in the youngest and oldest age groups than in the middle-aged groups (p = .025). Marital status was unrelated to Ho scores. These patterns of hostility are similar to the patterns of health indicators in the population. Because hostility has been found to be associated with adverse health outcomes, hostility may account for some of the demographic variations in health status. However, it is argued that research must first establish the generality of the hostility-health relationship across subgroups of the population.
