SELECTING A COST-EFFECTIVE SCREENING MEASURE FOR THE ASSESSMENT OF PRESCHOOL SOCIAL WITHDRAWAL

The utility of teacher judgment (rankings, ratings) and peer judgment (sociometric ratings) were studied as screening variables for preschool social withdrawal/responsiveness. Observational measures of preschoolers' interaction were used as the validation criterion based upon theoretical, empirical, and practical considerations related to development of a multipurpose behavioral assessment system. Results indicated that teacher rankings of students' verbal interaction frequencies (1) were most highly correlated to interaction rate in two preschool settings, (2) had test-retest reliability consistently above Rho = .80, and (3) were useful in that 77% of teachers using this procedure could identify their least socially responsive student within five rankings. The peer nomination sociometric rating was the least reliable measure at retest (Rho = .35) and showed consistently the lowest correlation with observational indices of interaction partner preferences, e.g., reciprocal rate (Rho = .29 to .39). The tendency for relationships among screening measures and the criterion to increase at retest suggested a training effect on screening accuracy. The use of teacher rankings in combination with observational measures to confirm selection accuracy and for monitoring treatment progress is discussed as a cost-effective behavioral assessment procedure for preschool social withdrawal/responsiveness.     

Utilization of college students to improve inner-city school children's academic behavior

A program using college students as tutor/counselors with low-achieving, inner-city, junior high school students is described and evaluated. The college students, who were primarily ethnic minorities, played a multifaceted role as tutors, counselors, and role models of academic achievement. The evaluation assessed program effects across groups (program versus control), two schools and two program administrations, using analysis of covariance. Results supported positive program impact in the students using teacher ratings of classwork effort, quality, and attitude, and in the students' self-reported attitudes toward education, educational aspirations, and expectations.     

PREDICTION AND PREDICATION

Nelson Goodman's own solution to his new riddle of induction turns on the degree to which predicates are entrenched in our use of language. However, this solution requires that judgements concerning the degree to which a predicate is entrenched can be made independently of any canon of perceptible similarity. I argue that this requirement cannot be met. The riddle itself depends upon the claim that since ‘green’ can be defined positionally in terms of ‘grue’ and ‘bleen’, ‘grue’ and ‘bleen’ are symmetrically related to ‘green’ and ‘blue’, and positionality is therefore ‘an entirely relative matter’. However, in order to establish that positionality is an entirely relative matter, we would need to provide a non-positional definition of ‘grue’, rather than a positional definition of ‘green’. We therefore need to decide whether ‘grue’ can be defined ostensively by means of a single sample, as ‘green’ can. I argue that any attempt to provide such a definition is bound to fail, and hence the new riddle of induction does not reveal that ‘the roots of inductive validity are to be found in our use of language’.     

Theory-based screening for prevention: Focusing on mediating processes in children of divorce

Prevention programs in mental health theoretically can benefit from selecting participants who have a greater likelihood of developing psychological problems because of their exposure to the putative mediators targeted for change in an intervention. Screening on mediators may increase statistical power to detect program effects, enhance the cost-effectiveness of intervention trials, and decrease the possibility of iatrogenic effects. The circumstances that optimize the strategy of screening on the basis of mediating variables are discussed, and data are presented to illustrate the development of a mediational selection strategy to identify families who might best benefit from a preventive intervention for children of divorce. In addition, we present evidence that adjustment problems for children experiencing a divorce, as with most mental health problems, are not the result of one specific factor, but are jointly determined by several mediating processes that occur subsequent to the divorce. The mediational selection strategy developed illustrates the utility of measuring a set of mediational processes central to conferring risk for mental health problems to children of divorce.     

A study of paranormal belief, magical ideation as an index of schizotypy and cognitive style

This study examined the proposal that the association between paranormal belief and magical ideation may be mediated by distinctive cognitive styles for schizotypes as compared to believers in the paranormal. Schizotypes were found to differ from an atypical group of believers in the paranormal and to resemble schizophrenics in terms of cognitive style. Believers expressed a cognitive style reliant on notions of personal responsibility while schizotypes emphasised the role of randomness. Believers differed from schizotypes on more deviant aspects of schizotypy measures yet unexpectedly these groups did not differ on specific facets of paranormal belief. It is tentatively proposed that for some people certain paranormal beliefs represent a cognitive ‘defence’ against acceptance of the uncertainty of life events, while for others paranormal belief may be indicative of psychopathology.     

Choice/Matching Preference Reversals in Groups: Consensus Processes and Justification-Based Reasoning

Individual preferences can vary significantly by the mode in which they are elicited. Thus, the seemingly benign procedural issue of elicitation mode (i.e., choice, buying price, rating, matching) could have a profound effect on group decisions, although elicitation mode has not been much studied as a group procedural variable. Individual preferences differ by elicitation mode when the elicitation contexts differentially emphasize particular aspects of the decision. Emphasis on explainability, for example, may produce decisions that are based only on a few, important, attributes. Because group consensus processes also can encourage particular reasoning strategies, grouping may interact with elicitation mode; that is, group consensus processes may moderate or exacerbate preference reversals. The present study explored a particular elicitation effect, choice versus matching preference reversals, for decisions with both low and high social significance. The results confirmed both that elicitation mode can affect group decisions and that group consensus processes moderate choice/matching preference reversals. Further, evidence from both preference measures and rating scales suggested that the moderation was due to an increase in easily defended, justifiable decisions. Social significance did not affect individual or group decisions, but decreased members′ post group commitment to the group decision. These results have implications both for group decision making and for the study of the role of explanation-based strategies in preference formation.
