Potential influence structures as sources of interpersonal conflict in groups and organizations

It is argued that conflict in organizations can be interpreted, in many cases, as conflict over who is to exert influence, and that this conflict, in turn, is caused by structural incongruencies in the distribution of potential influence in groups and organizations. Potential influence is described in terms of the structural relations defined by Structural Role Theory. At the psychological level, conflict is explained as a result of incompatible expectations among people about their relative influence, their desire to protect valued roles, and to maintain a sense of freedom. The implications of the present hypothesis for specifying the range of conflict situations, the type of conflict behavior, and conflict management are explored.     

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).     

Why does self-reference promote incidental encoding?

Answering a question regarding a stimulus word can cause incidental encoding of the word itself. The thoroughness of the encoding depends in part upon what question is answered. For example, saying whether a word describes oneself causes a particularly high degree of incidental encoding. The study reported here investigated several variables that have been proposed as mediators of that effect. As in previous research, subjects completed an incidental-encoding and recall procedure. They then rated (a) the quality and degree of affect that they would experience if each stimulus word were to be applied to them, (b) the importance to them of the behavioral/psychological dimension implied by the stimulus word, and (c) the degree to which they saw themselves as distinctive on that dimension. As in previous studies, deciding whether a word described the self increased the likelihood of subsequent recall. There also was a highly significant interaction such that words judged to be applicable to self were recalled better than those judged not to be applicable. There was no evidence, however, of a mediational role for any other variable studied. Discussion centers on theoretical implications of the data.     

Motor perseverative behavior in adult stutterers and nonstutterers

The performances of 22 adult stutterers and 22 adult nonstutterers on motor tasks requiring the graphic reproduction of a sequence of alternating figures following the production of a series of nonalternating figures were studied. The finding that there were no differences in the performance of the two groups on the alternating motor tasks was interpreted as challenging the validity of previous observations that motor perseverative behavior exists in stutterers and is indicative of a central neurological deficit in that population.     

Event-related potentials in neuropsychological studies of language

Experiments are described in which event-related potentials (ERPs) are employed to study the specialization of functions between and within the cerebral hemispheres during the performance of language and nonlanguage tasks by normal adults. Similar studies of deaf subjects suggest that the functional organization of the brain may be altered after different early language and sensory experiences. Studies of patients with alexia without agraphia suggest that the ERP may be a valuable tool with which to study cerebral reorganization after brain damage.     

Channel capacity and processing of modality specific information

The synthesis model, designed to explain effects of modality specific information on retention, is presented and tested. The model encompasses qualitative and quantitative components. The qualitative characteristics reflect the physiological properties of the auditory and visual channels. Three parameters are assumed to affect the quantitative efficiency of the channels. Each channel is assumed to have a certain capacity, and processing of information in the channels is determined by situational demands. Furthermore, processing in a channel is regarded as superficial. Increased allocation of processing to the superficial level was manipulated by the use of modality specific distractors and conditions of ‘supracapacity load’. Transformation of information from the visual to the auditory channel was controlled by the use of one mixed-mode and one single-mode experiment. Thirty subjects participated in the mixed-mode experiment and 60 in the single-mode experiment. Both experiments employed an identical distraction task, intervening presentation and free recall of the to-be-remembered items. The results confirmed the predictions of (a) modality specific distraction, (b) supracapacity performance decrement, (c) a larger distraction effect for the auditory channel and (d) transformation effects in the single-mode experiment.     

Tests of sphericity of normal distributions and the analysis of repeated measures designs

The locally best invariant test statistic for testing sphericity of normal distributions is shown to be a simple function of the Box/Geisser-Greenhouse degrees of freedom correction factor in a repeated measures design. Because of this relationship it provides a more intuitively appealing test of the necessary and sufficient conditions for valid F-tests in repeated measures analysis of variance than the likelihood ratio test. The properties of the two tests are compared and tables of the critical values of the Box/Geisser-Greenhouse correction factor are given.     

Temporal aspects of retrieval in short-term serial retention

In three experiments, temporal properties of memory retrieval are studied. Latency of positionally probed recall of a single item is measured as a function of its serial position (SP) in a serial list. The requested SP is indicated by a positional probe, presented immediately after the list. For two organizational structures of the list (i.e., grouped vs. ungrouped lists) the experiments study the effects of precueing the probe position briefly before probe presentation, the cue signal indicating the SPs relevant for recall. The problem of confounded effects on latency of requested SP and of probe-signal location is also investigated. A bow-shaped SP-curve is found for ungrouped lists; precueing reduces RT but does not affect the bowed shape. This argues against selective confounding effects of spatial probe position and also suggests that precueing preactivates memory access. Grouping the items into two sublists eliminates precueing effects for items around the group boundary. Furthermore, precueing is detrimental when SPs at opposite ends of the list are precued. This suggests that the available points of memory access can only be utilized one at a time, so that precueing is not beneficial when the item cannot be reached via the preactivated point. Although the notion of single access to memory is in accord with both positional cueing theory and non-associative hierarchical theories (e.g., Estes 1972), various details of the results are in favor of the first type of explanation.     

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.     

Collaborating careers: The differential effects of race

Male and female black undergraduates enrolled in Introductory Psychology and Human Development courses at a predominantly black university responded to five stories about married black physicians whose total income was greatest, respectively, when the husband cared for the children (Story 1), the wife cared for the children (Story 2), either spouse cared for them (Story 3), the wife earned more than the husband (Story 4), or the husband earned more than the wife (Story 5). In contrast to the results of a study completed at a predominantly white university, black females favored maternal child care even when, as a result, the family income was reduced and had significantly less of a preference for higher relative salary for the wife than did females in the study at a predominantly white university; although black males preferred maternal child care in Story 2 and Story 3, the preference was significantly less than that of males in the study at a predominantly white university. The results were discussed in terms of their relevance to collaborating career patterns among middle-class black families.
