Stimulus preference assessments and the utility of a moderate category

Recent studies have shown that moderate (Piazza, Fisher, Hagopian, Bowman, & Toole, 1996 ) and low (Taravella, Lerman, Contrucci, & Roane, 2000 ) ranked items on stimulus preference assessments may function as reinforcers. Following an initial preference assessment the current study analyzed whether moderate or low preference items were more likely to be ranked as high preference on subsequent preference assessments. Results show that for five of the seven participants additional high preference items were identified from the moderate preference set, while additional high preference items were identified from the low preference set for only one participant. Results are discussed in terms of the need to identify multiple reinforcers and the composition of the stimulus array during preference assessment. Copyright © 2006 John Wiley & Sons, Ltd.     

Evolutionary preference/utility functions: A dynamic perspective

The collection of repeated measures in psychological research is one of the most common data collection formats employed in survey and experimental research. The behavioral decision theory literature documents the existence of the dynamic evolution of preferences that occur over time and experience due to learning, exposure to additional information, fatigue, cognitive storage limitations, etc. We introduce a Bayesian dynamic linear methodology employing an empirical Bayes estimation framework that permits the detection and modeling of such potential changes to the underlying preference utility structure of the respondent. An illustration of revealed stated preference analysis (i.e., conjoint analysis) is given involving students’ preferences for apartments and their underlying attributes and features. We also present the results of several simulations demonstrating the ability of the proposed procedure to recover a variety of different sources of dynamics that may surface with preference elicitation over repeated sequential measurement. Finally, directions for future research are discussed.The authors wish to acknowledge and thank the Editor, the Associate Editor, and two anonymous reviewers for their constructive and insightful comments.

Ice cream preference: the relationship of cost and quality

Junior high students showed a preference for inexpensive ice cream while adults preferred more expensive ice cream; university students were in a middle position. It appears that taste for more expensive ice cream is associated with age, but it is not clear whether this is learned although it appears to be inasmuch as it is not universal across the various groups.     

Efficacy of and preference for reinforcement and response cost in token economies

Researchers have shown that both differential reinforcement and response cost within token economies are similarly effective for changing the behavior of individuals in a group context (e.g., Donaldson, DeLeon, Fisher, & Kahng, 2014; Iwata & Bailey, 1974). In addition, these researchers have empirically evaluated preference for these procedures. However, few previous studies have evaluated the individual effects of these procedures both in group contexts and in the absence of peers. Therefore, we replicated and extended previous research by determining the individual effects and preferences of differential reinforcement and response cost under both group and individualized conditions. Results demonstrated that the procedures were equally effective for increasing on‐task behavior during group and individual instruction for most children, and preference varied across participants. In addition, results were consistent across participants who experienced the procedures in group and individualized settings.     

Subjective utility,anticipated utility,and the Allais paradox

One of the most notable counterexamples to expected utility theory is the “Allais paradox” (M. Allais, 1953, Econometrica, 31, 503–546). A number of alternative theories have been proposed in an attempt to resolve this paradox, notably including Karmarkar, 1978, Karmarkar, 1979, 24, 67–72). It is shown that SWU theory necessarily involves violations of dominance, but that the theory can be modified to avoid these violations. The result is a special case of J. Quiggin's anticipated utility theory (1982, Journal of Economic Behaviour and Organisation, 3, 323–343).     

Cooperation,fairness and utility

Conclusions In the situations canvassed I have argued that (a) the dominant aim of the utilitarian will be the establishment of a fair procedure, (b) under radical uncertainty cooperation will constitute his best bet, and (c) when he knowsthat all others will cooperate it is still an open question whether he will slack, and if under some conditions he does so he does not then act unfairly. It is wise to bear in mind, however, that an enormous number of possible situations, mostly mixtures of the pure cases, simply have not been considered. It is not inconceivable that in one of them the utilitarian will clearly act unfairly; I am inclined to think not, but the possibility is not entirely ruled out.An earlier version of this paper was read on March 9, 1969 as part of a Colloquium in Political Philosophy held at the University of Toronto. I am much indebted to David Lyons for the helpful comments he delivered on that occasion; many of the subsequent revisions in the paper have been made in the light of those comments.     

Actual utility,the mismatch problem,and the move to expected utility

The mismatch problem for consequentialism arises whenever the theory delivers mismatched verdicts between a group act and the individual acts that compose it. A natural thought is that moving to expected utility versions of consequentialism will solve this problem. I explain why the move to expected utility is not successful.     

Self-assessment,self-enhancement,and task preference

If task choice depends on a person's interest in the accurate assessment of his or her abilities, task attractiveness should be positively related to the diagnosticities of all performance outcomes with regard to one's ability level. In contrast, the view that people are primarily interested in maximizing pride or mininizing shame would predict that task attractiveness is positively related to the diagnosticity of success but negatively related to the diagnosticity of failure. To test these predictions, subjects were presented with tasks that varied orthogonally in the extent to which success was diagnostic of high ability level and the extent to which failure was diagnostic of low ability level. Consistent with the self-assessment view, task attractiveness increased both with the diagnosticity of success and with the diagnosticity of failure. Furthermore, both effects were more pronounced for high achievement motive subjects than for low achievement motive subjects. This result lends support to the self-assessment view, which assumes that high achievement motive subjects are more interested in attaining the ability-relevant information contained in any performance outcome.     

Complexity,response competition,and preference

In an attempt to resolve disagreements about the events underlying repeated exposure to a stimulus and the affective consequences of these events, two experiments examined psychological complexity and response competition (two measures of the uncertainty produced by a stimulus) as related to each other and to liking and goodness of meaning ratings of Chinese characterlike stimuli. In Experiment 1, 60 undergraduates' mean latency of first free association to the stimuli (response competition) increased as a perfect monotonic function of the number of lines constituting them (psychological complexity). In Experiment 2, ratings of liking by 40 undergraduates were highest for stimuli associated with an intermediate level of uncertainty (psychological complexity and response competition). Thus it was speculated that a moderate number of stimulus exposures (reducing uncertainty to an intermediate level) is preferable to an indefinitely large number of exposures (reducing uncertainty to a minimal level). The finding of no relationship between rated goodness of stimulus meaning and uncertainty was judged to be consistent with Stang's (1974) hypothesis that characteristically observed increases in rated goodness with increasing stimulus exposures (decreasing uncertainty) are a result of subject intuitions rather than an effect of decreasing uncertainty.     

Entropy,visual diversity,and preference

The author reports relationships between subjective impressions of visual diversity or pleasure with statistical entropies of stimuli. The stimuli were 34 rows of houses that varied in color, scale, and shape, or in shape and articulation. Entropies ranged from 0.0 to 5.6 bits. Fifty-seven participants rated the stimuli on scales of pleasant/unpleasant and uniform/diverse. The relationship between rated diversity and entropy was strong and linear. The relationship between rated pleasure and entropy was either linear or asymptotic, but no evidence was found for an inverted U relationship.     

Notes on Psychoanalysis,Psychotherapy and Methodology

Abstract

Technical innovations always carry with them clinical and scientific challenges. The aim of this paper is to provide a context for exploring the consequences of technical innovations for psychoanalysis as an interrelated method of observation, treatment, and body of knowledge about mental functioning. The problems are approached from a methodological perspective because scientific progress requires methodological clarity. The inquiry begins with a methodological investigation of the technical and theoretical consequences of first principles, that is, the consequences of the assumptions and methods we adopt for the kind of data that are obtained by their application and for the theory required to understand and unify the resulting observations. The conclusion suggests that if one organizes a doctor-patient relationship around the clinical-historical and free-association methods with the aim of removing all obstacles to communication, if the understandings that emerge include a full range of dynamic, structural, genetic and adaptive propositions, one is engaged in psychoanalytic inquiry. The circumstances under which Rothstein's technical recommendations enable such understandings to develop are an important topic for future research.
