Some applications of problem-solving versus decision-making to management

Two contrasting views of decision theory and of problem solving are presented. One view is that the decision-maker is a problem solver with available alternatives from which to choose. The other view is that decision-making processes and those in problem solving differ in kind. In the latter view, decision making is the selection of an alternative; problem solving, the invention of an alternative different in meaningful ways from any previously existing. The distinctions between the two points of view are elaborated mainly in the context of conflict resolution. Illustrations are presented of applications of problem solving to potential conflict between a lecturer and an already hostile group; to conflict between departments in an organization; to confict between individuals and to internal incapacitating conflict of an individual. Additional illustrations are given of management problems not involving conflict. These offer choices between alternatives as well as the opportunity to resolve the choice through problem solving. The latter yielded solutions different from and superior to either existing alternative.     

Three loneliness scales: an assessment of their measurement properties

In loneliness research, there has not been a consensus concerning either the factorial structure of most loneliness scales or the factorial structure of each of the proposed dimensions of loneliness. We investigated theoretical and operational definitions, as well as the factorial structure, based on gender of three loneliness scales: the University of California at Los Angeles (UCLA) Loneliness Scale, the Loneliness Deprivation Scale, and the Emotional/Social Loneliness Inventory. Unidimensional, best-fit models of the structures of these scales are presented.     

Need for achievement and performance on measures of behavioral fluency.

This investigation was designed to assess the relationship between a validated personality characteristic, need for achievement (nAch), and performance on measures of behavioral fluency. To infer this relationship, 50 neurologically intact college undergraduates were administered a questionnaire assessing nAch and a battery of tests including a short form of the WAIS and measures of behavioral fluency (i.e., verbal fluency). Statistical analysis indicated that subjects high on nAch obtained higher scores than subjects low on nAch on the measures of figural fluency and the WAIS Verbal Scale. No significant difference on verbal fluency was seen between the two groups. Secondly, the group high on nAch also had a higher mean Verbal IQ but not a higher mean Performance IQ as measured by a short form of the WAIS than did subjects scoring low on nAch.     

APPROXIMATING CHAOTIC BEHAVIOR

Abstract— Human subjects received feedback showing how closely their responses approximated the chaotic output of the logistic difference function. In Experiment 1, subjects generated analog responses by placing a pointer along a line. In Experiment 2, they generated digital responses in the form of three-digit numbers. In Experiment 3, feedback was sometimes provided and other times withheld. Responses came to approximate three defining characteristics of logistic chaos: Sequences were "noisy," they were extremely sensitive 10 initial conditions, and lag I autocorrelation functions were parabolic in form. Chaos theory may describe some highly variable although precisely determined human behaviors.     

An internal consistency check for scale values determined by the method of successive intervals

The method of successive intervals is a psychological scaling procedure in which stimuli are classified into successive intervals according to the degree of some defined attribute which they are judged to possess. A psychological continuum is defined and the scale values are then taken as the medians of the distributions of judgments on the psychological continuum. It is assumed that the distributions of judgments for each stimulus are normal on the psychological continuum as defined.An internal consistency check indicates that the cumulative distributions of empirical judgments for the various stimuli can be reproduced by means of a limited number of parameters with an average error that compares favorably with that usually reported for paired comparison data. Furthermore, the scale values obtained by successive interval scaling, for the data reported, are shown to be linearly related to those obtained by the method of paired comparisons.This paper was written while the first author was a post-doctoral Research Training Fellow of the Social Science Research Council studying at the University of Chicago.

Checkerboard-specific color aftereffects: A failure to find effects of perceptual organization

Two experiments investigated the effects of differing perceptual organizations of reversible figures on McCollough aftereffects. Experiment 1 used colored checkerboard inducing stimuli and achromatic grating test stimuli. While some subjects tended to organize the checkerboards into rows and/or columns and others to organize them into obliques, these variations did not result in differences in aftereffect direction or magnitude. Experiment 2 induced an aftereffect with colored gratings and tested with checkerboards, gratings, and a reversible concentric octagon pattern. Perceptual organization had no effect on results for checkerboards, but was related to aftereffect strength for the octagon pattern. Indirect evidence suggests that, in the latter case, differences in aftereffect strength may have influenced the perceived organization, rather than vice versa. Finally, regardless of the specific organization perceived, spontaneous viewing of all test stimuli produced stronger aftereffects than were found when subjects reorganized the pattern. This may have resulted from a viewing strategy associated with reorganization, since similarly small aftereffects were found when subjects concentrated their attention on a single pattern element.     

Natural anchoring at the neutral point of category rating scales

Contextual theories of judgment assume that the rating of any stimulus depends on its relationship to a context of similar stimuli. For example, any specific act of behavior would be rated less favorably when considered in the context of good behaviors then when considered in the context of bad ones. However, two experiments suggest an absolute anchoring of the natural neutral point, an exception to this generalization. In Experiment 1, morally indifferent acts remained “neutral,” regardless of context; and in Experiment 2 the break-even or zero-point in a simulated game of chance was always rated “neutral.” In both experiments, contextual manipulations had powerful effects upon ratings of other stimuli, though never shifting them across the neutral point. Furthermore, both experiments suggest that neutral-point anchoring also affects the use of the most extreme categories in a manner that is unique to this phenomena. In Experiment 2 for example, the introduction of extremely positive “wins” not only made other wins seem less favorable while leaving ratings of the zero-point unchanged, but also made the most negative losses seem more favorable. It is as if the introduction of an extremely positive “win” also introduces the possibility of an extremely negative “loss.” Taken together these findings contradict the basic adaptation-level premise that the entire scale is determined by the neutral point; they are also inconsistent with the assumption of range theories that the scale is anchored by the endpoints of the range of stimuli actually experienced.     

Analogic and abstraction strategies in synthetic grammar learning: A functionalist interpretation

Subjects learned artificial grammars under two conditions of acquisition: paired-associate learning and observation of exemplars. The former procedure was strongly associated with the establishment of a fairly concrete memorial space consisting of specific items and parts of items and the use of an analogic strategy for making decisions about novel stimuli. The observation procedure was strongly associated with the induction of an abstract representation of the rules of the grammar and the use of a correspondence strategy for decision making. Moreover, this latter procedure led to more robust knowledge and better overall performance. Analyses of both objective response patterns and subjective introspections yielded coordinated data in support of this distinction. The relationships between acquisition condition and cognitive strategy are discussed from a functionalist point of view.
