On the relations between random walk models for two-choice response times

We state a condition on the moment-generating functions of the random walk model derived by Link and Heath (1975), which is necessary and sufficient to yield the sequential probability ratio test of Wald (1947) and the reaction-time model proposed by Stone (1960). A restricted form of this condition can also be obtained by imposing the types of symmetries on the moment-generating functions considered by Link and Health (1975) and Thomas (1975). The various conditions are contrasted and their implications for empirical investigation are discussed.     

Causal attributions and information seeking to explain success and failure

Previous studies of attributions for success and failure have relied upon a theoretically derived set of causal attributions, either luck versus skill (derived from Rotter, 1966) or ability, effort, luck, and task difficulty (Weiner et al., 1971; Weiner, 1972). The same tendency of relying upon a set of logically derived cues has been evident in investigations of information-processing in making attributional judgments for success and failure (e.g., Fontaine, 1972; Frieze & Weiner, 1971). Two studies were conducted which employed an open-ended format to determine the relevance of the causal categories and information which have been utilized in previous studies. Results of these studies supported the validity of previously employed causal categories and information cues as well as establishing other important but previously ignored causes and sources of information.     

Elkind on egocentrism

The purpose of this paper is to respond to D. Elkind's (1985, Developmental Review, 5, 218–226) reply to D. Lapsley and M. Murphy's (1985, Developmental Review, 5, 201–217) critique of the adolescent egocentrism theory. After a reprise of the issues in contention, we address the problem of theoretical consistency and self-other differentiation in Dr. Elkind's (1967, Child Development, 38, 1025–1034) theory. The role of formal operations in the Lapsley and Murphy (1985) account of the imaginary audience and personal fable is revised, and the empirical support for Elkind's theory is reviewed. We conclude that there are good conceptual and empirical grounds for doubting the major assumptions of the adolescent egocentrism theory, and that the Lapsley and Murphy (1985) framework has promise in suggesting theoretical integration with other approaches to the self.     

Comment on Bernbach's prediction of the invariance of Type 2 d′ in confidence-rated recall

Bernbach Bernbach, 1967, Bernbach, 1971 has claimed that empirical findings of Type 2 d′ invariance in confidence-rated recall experiments confirm a prediction of his two-state theory of recognition and disprove strength theories of memory. In order to derive this prediction from his recognition theory, Bernbach (1967) found it necessary to add to the theory an assumption concerning recall processes. However, this recall assumption is untenable, as it leads to an empirically false prediction concerning accuracy on recognition and recall tests. Moreover, an alternative recall assumption proposed by Bernbach and Kupchak (1972) does not lead to a prediction of Type 2 d′ invariance. Thus, Bernbach's theory predicts the invariance of Type 2 d′ only with the aid of an untenable recall assumption. Consequently, empirical findings of Type 2 d′ invariance cannot be regarded as supportive of Bernbach's theory.     

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).     

Resistance to yielding and the expectation of cooperative future interaction in negotiation

The expectation of cooperative future interaction (ECFI) encouraged especially high joint benefit (the total of the two bargainers' individual outcomes) when resistance to yielding was high, but especially low joint benefit when resistance to yielding was low. Process data suggest that this finding can be explained as follows: When resistance to yielding is high, ECFI encourages problem solving and reduced contentious behavior; when resistance to yielding is low, ECFI encourages a collapse of aspirations. The results support Filley's (1975) dualconcern model and cast doubt on Deutsch's (1973) blanket assertion that a cooperative process leads to constructive conflict resolution.     

The interaction of locus of control expectancies and providing purpose on children's motivation

Children differing in locus of control orientation (internals, mediums, and externals' were administered an extended coding task following either a fictional rationale for the study (purpose incentive statement) or no purpose. As predicted, externals' performance under no purpose was significantly poorer and their rated interest in the task was significantly less favorable than those of internals. Also as predicted, these differences were nullified under the purpose incentive condition. The findings extend Lefcourt's (1967) suggestion that cue explication is important for externals to include external children, and support the position (Mischel, 1973; Rotter, 1975) that personality variables are increasingly important as a function of greater situational ambiguity. Implications of these findings for education and child-rearing are discussed.     

Traits,processes, and the purpose of templates

The template method proposed by D. J. Bem and D. C. Funder 1978, Psychological Review, 85, 485–501) can have two separate purposes. First, template-behavior pairs can be used as a type of explanation in which situational influences are incorporated within a trait theory. Second, template matching can be used as a method for evaluating process theories. Recent discussion (D. J. Bem, 1983; Psychological Review, 90, 390–393; D. C. Funder, 1983; Psychological Review, 90, 283–289; W. Mischel & P. K. Peake, 1982, Psychological Review, 89, 730–755) confuses these two purposes. If used as a type of explanation, then templates can be criticized on the grounds of blunt empiricism; but if templates are used as a method for evaluating process theories, then process theorists should welcome this new technique.     

Equity judgments in hypothetical,four-person partnerships

Subjects' ratings of the fairness of a set of suggested allocations in hypothetical, four-person partnerships demonstrated that an ordinal relationship between inputs and outcomes is not a sufficient definition of equity. Subjects' suggestions for fair distributions of outcomes failed to conform to G. W. Walster's (Representative Research in Social Psychology, 1975, 6, 65–67) increasing-profits and profit-sign criteria, and were better fit by R. J. Harris' (Journal of Experimental Social Psychology, 1976, 12, 194–209) linear formula than by any other formula thus far proposed.     

Occupational prestige: Exploration of a theoretical basis

Drawing on the theory and research of psychophysics, a nonlinear model is hypothesized to explain the connection between education and income and occupational prestige. To achieve this, Weber's (R. L. Gregory, 1981, Mind in Science, Cambridge, Cambridge Univ. Press, pp. 501–503) and Stevens' (S. S. Stevens, 1970, Science170, 1043–1050) laws are brought together in an intrinsically nonlinear model. Guided by the earlier work of R. L. Hamblin (1971, Sociometry, 34, 423–452) and others, the work of O. D. Duncan (1961, in A. J. Reiss, Jr., O. D. Duncan, P. K. Hatt, & C. C. North (Eds.), Occupations and Social Status, New York, Free Press) is reanalyzed testing the possibility that work on the socioeconomic index can be understood as a prestige allocation process which follows psychophysical principles. That is, prestige is assigned to occupations, given specifiable levels of educational and income attainment, in a manner parallel to the way in which individuals respond to changes in the intensity of other stimuli. Using first the data developed by Duncan (1961) to test the model and the 1963 NORC data (R. W. Hodge, P. M. Siegel, & P. H. Rossi, 1964, American Journal of Sociology, 70, 286–302) to replicate it, a measurement model consistent with the theoretical model is evaluated. Comparing the results of the nonlinear model to that of the linear, it is concluded that a model is obtained yielding theoretical confirmation with no loss in predictive accuracy. The resultant nonlinear model yields alternative substantive implications concerning the relative influence of income and education on occupational prestige to those to be inferred from linear models. Perhaps most important, however, is the candidacy given by these results to psychophysics as the explanatory mechanism in the prestige allocation process.     

Efficient sets,decision heuristics,and single-peaked preferences

The origins of single-peaked preferences in multiattribute choice behavior are analyzed. The starting point is (a), (b), 16, 261–266) theory which explains single-peakedness as the joint effect of task and behavior characteristics. Whereas the task conditions—so-called efficient sets—are retained, and their importance is even more stressed, it is argued that Coombs and Avrunin's behavioral assumptions—classical marginally decreasing preference functions—may not be representative of actually displayed choice behavior. Rather, the information processing approach to decision research has shown that multiattribute choices are often based on simplifying heuristic rules which, due to their possible intransitivity, are inconsistent with Coombs and Avrunin's behavioral requirements. Tversky's (Psychological Review, 1969, 76, 31–48) additive difference model is used as an algebraic framework for analyzing such so-called attribute-based choice rules. Sufficient (and in the continuous case also necessary) conditions are presented which guarantee that the additive difference model will also be single-peaked on efficient sets. These conditions show that the behavioral principles yielding single-peaked preferences are far more general than Coombs and Avrunin assumed and include most of the empirically substantiated forms of attribute-based choice rules. Further, a necessary and sufficient condition is derived which insures that elimination rules, like the conjunctive rule, for instance, and generalizations thereof are single-peaked. Finally, making use of a result by Edgeworth, (Mathematical Psychics, London, Paul, 1881), it is shown that efficient sets per se may originate in quite different ways. It is concluded that the phenomenon of single-peakedness is mainly a function of the task rather than of some specific behavior.     

Still no evidence for visual discrimination learning: A reply to Lett

Neither of the points made by Lett (1977) regarding the data from my experiments (Roberts, 1976) can be taken as evidence of visual discrimination learning with a 1-min delay of reward. If it is concluded that the Lett Group of my second experiment improved over blocks of trials but the other three groups tested in my experiments did not, this can lead only to the conclusion that rats in my Lett Group and in Lett's original experiment (Lett, 1974) improved on the basis of odor cues and not associations between chamber brightness and reward. The significantly higher frequency of initial choices of the black chamber found for black-rewarded animals over white-rewarded animals is shown to result from differential rates of stimulus satiation for animals whose initial chamber preferences agree or disagree with their designated S+.     

Brain responses related to semantic meaning

Evoked Potentials from electroencephalogram (EEG) recording were averaged to many visually presented word stimuli whose semantic meanings were specified along Osgood's semantic dimensions of Evaluation, Potency, and Activity [Miron &; Osgood, 1966, in R. B. Cattell (Ed.), Handbook of multivariate experimental psychology, Chicago: Rand-McNally; Osgood, 1971, Journal of Social Issues, 27, 5–63; Osgood, May, &; Miron, 1975, Cross-cultural universals of affective meaning, Urbana, Ill.: University of Illinois Press]. Multivariate analyses classified the Evoked Potentials to six semantic classes with success rates more than twice chance expectation. The pattern of brain activity related to the six semantic classes was similar for (i) two sets of words, (ii) 10 subjects used to develop the analyses, and (iii) an added, new subject.     

Interal locus of control as a value

Internal and external subjects, who previously filled out Rotter's (1966) I-E scale, were asked to score the I-E scale of “another student”. Subjects were exposed to “an other's” score of either 0, 5, 10, 16, or 23, and were asked to rate themselves and the “other” on an evaluative questionnaire. It was predicted that ratings of the “other” would increase in positivity to the extent the “other” scored as an internal. A reverse direction was predicted for an index of negative evaluations. The predictions were confirmed. The results suggest that internal locus of control is a societal value. The findings did not support either Hannah's (1973) hypothesis that internals are more responsive to a need for social approval, or Byrne's (1969) similarity hypothesis.     

Do birds of a feather flock together? A test of the similarities within and the differences between five occupations

Two sets of samples of 40 women from each of five different occupations were subjected to J. H. Ward's (Journal of the American Statistical Association, 1963, 58, 236–244) hierarchical cluster analysis, using an index of similarity from Kuder, 1977, Kuder, 1980, 40, 1–8). The five-group solution in neither case adequately recaptured the occupational membership of the original groups. This finding was interpreted to mean that there may be important differences in the interests of person in the same occupation, which in turn has implications for occupational scaling on interest inventories and theories of career development and counseling.     

The abstraction of visual prototypes by children

The present studies demonstrated that children as young as second graders could form prototypical representations from a set of highly similar stimuli. The prototype-plus-transformation model of this performance (Franks & Bransford, 1971) was contrasted with an attribute-frequency model (Neumann, 1974). Results supported the latter model when trigram stimuli were used to test differential predictions from the models.     

The case of the disappearing disagreements: A reply to Yussen

S. R. Yussen (1984, Developmental Review, 4, 139–144) and I have few disagreements. The major one seems to be in what the purpose of my article (R. J. Sternberg, 1984, Developmental Review, 4, 113–138) should have been. I believe the article fulfills my own purpose, if not Yussen's.     

The applicability of Holland's typology to clients

Holland, 1966, Holland, 1973 has generated a vast amount of research seeking to validate or to challenge the hexagonal model and the associated constructs of consistency and differentiation. A review of the studies related to Holland's typology, however, reveals a very small number of studies with clients as subjects. The present study was an evaluation of Holland's model using the General Occupational Themes of the Strong-Campbell Interest Inventory (SCII) (D. P. Campbell & J. C. Hansen, Manual for the SVIB-SCII, 3rd ed., Stanford, Calif.: Stanford Univ. Press, 1981) obtained from college students who had sought vocational counseling. The use of the hexagonal model as a framework for the interpretation of relationships among the SCII General Occupational Themes was supported, and the SCII was found to be a valid instrument for vocational counseling in a client population.     

Intervention and sleeper effects: A reply to Victoria Seitz

Victoria Seitz (Developmental Review, 1981, 1, 361–373) has misperceived and misunderstood our position (A. D. B. Clarke & A. M. Clarke, Developmental Review, 1981, 344–360). For example, our argument endorsed a transactional and not a main-effect model, nor was our aim to argue that early intervention has no important later consequences, nor did we dispute Consortium findings (I. Lazar & R. Darlington, Lasting effects after preschool, Washington, D.C.: DHEW Publication No. (OHDS) 79-30178, 1978). In fact, agreements with Seitz greatly exceed disagreements. Our skepticism about whether a behavioral treatment can have long-range effects without also having earlier ones remains. Long-term changes appear to result from ongoing long-term processes.     

Effects of self-awareness on antinormative behavior

Based on Zimbardo's (1970) theory of deindividuation and Duval and Wicklund's (1972) theory of “objective self-awareness” it was predicted that self-awareness would lead to a decrease in transgressive behavior. Subjects were either made self-aware (seated in front of a mirror listening to their own tape-recorded voice) or nonself-aware (seated to the side of the mirror listening to another's voice) and were given an opportunity to cheat on an anagrams test. Significantly more cheated in the nonself-aware condition (71%) than in the self-aware condition (7%). The results support the basic premise of deindividuation theory that self-awareness influences impulsive, counternormative behavior and suggest that an integration of the theories of deindividuation and objective self-awareness is possible.
