Deconstructing Locus of Control: Implications for Practitioners

Locus of control is demonstrated as being an important individual belief for counselors to consider in their work. Western cultural bias that has influenced the research with locus of control, and may influence how counselors conceptualize clients' problems, is the notion that internal control is always more desirable than external control. Several areas of locus of control theory are reviewed, including sociocultural influences in the formation of the theory, cultural differences in locus of control, and differing conceptualizations of the construct. In addition, selected research with locus of control and mental health is briefly reviewed. Finally, important implications for practitioners are suggested.     

Circle size and diameter tilt: A new look at integrality and separability

In six experiments using the speeded classification paradigm, we provide evidence that the ostensibly “separable” dimensions of size and orientation can produce patterns of either separability or asymmetric configurality, depending on the spatial arrangement of the stimuli. In all experiments, subjects classified large or small circles contairting a single line in one of two possible orientations. When the line touched the circle’s perimeter, thereby defining the diameter of the circle (Experiments 1–4), asymmetric configurality obtained: Variations in size interfered with classification by orientation, but variations in orientation did not interfere with classification by size, and redundancy gain was weak or absent. When the lines fell completely within (i.e., did not touch) the circles (Experiments 5 and 6), the results were consistent with separability: There was neither redundancy gain nor interference. Taken together, the results add to the growing body of evidence that classification of specific dimensional pairs as separable or integral may be less feasible than identifying the more general conditions that increase or decrease the psychological salience of dimensional structures and facilitate or interfere with selection of optimal processing strategies.

Perceived trait-co-occurrences according to managerial role: A structural representation

Fifty-eight middle managers were presented with three check lists containing effective and ineffective managerial traits previously obtained as free responses from another sample of middle managers. Each manager in the present study was asked to describe a superior, a peer, and a subordinate. Multidimensional scaling solutions were then calculated from these check list data. Ratings, obtained on five properties, were used to interpret the solutions.The findings demonstrated that managers in a highly competitive organization having frequent, formalized evaluative procedures (1) ascribe highly negative attributes to those peers perceived as effective, (2) have relatively undifferentiated views of their ineffective peers and ineffective subordinates, but (3) not their superiors who are viewed critically whether effective or ineffective.     

The effect of adults' eating on young children's acceptance of unfamiliar foods

Adults presented unfamiliar foods to 14- to 20- and 42- to 48-month-old children individually in their homes. More children put the food in their mouths when the adults also were eating than when the adults simply were offering the food. More children put food in their mouths when their mothers were the source than when the source was a friendly adult “visitor”. However, even when alone with a child, the visitor's eating elicited reliably more tasting. Analysis of requesting behavior indicated that the adults' eating aroused a desire to eat in the children. There were no consistent sex differences or interactions between sex of visitor and sex of child in children's food acceptance. There was a suggestion that younger children were more affected by repeated offerings than were older children. It is concluded that a relatively “low level” form of observational learning—“social facilitation”—can account for the data.     

Sequential dependencies and response range in cross-modality matches of duration to loudness

Subjects matched durations of keypresses to loudnesses of pure tones. Resulting duration responses were found to be assimilated to the value of the immediately preceding stimulus and responses from one to at least six trials back in the sequence of loudness stimuli. Responses were contrasted with the values of stimuli two through six trials back in the sequence. These sequential dependencies and other properties of the data were predicted by a cognitive model in which cross-modality matches are mediated by category judgments of stimuli on both continua, and subjects use heuristic strategies to reduce response uncertainty.     

Use of markov-encoded sequential information in numerical signal detection

Twelve Ss made binary decisions with feedback on numbers from one of two normal distributions with equal variances and unequal means. Sequences of distribution choices corresponded to first-order two-state Markov processes with probabilities of change of state of p₁ = p₂ = .50, p₁ = p₂ = .75, and p₁ = p₂ = .25. Performance was best (in d’ terms) when p₁ = p₂ ≠ .50. First-order sequential response dependencies tended to mirror the first-order stimulus dependencies. Violations of a fixed cutoff point decision rule were concentrated in the region of the average critical point, with a bandwidth of about 1/2σ, in which violations were strikingly more frequent than would be expected if they had occurred randomly. These results imply that in this task Ss are using a criterion-band decision rule instead of a fixed cutoff point rule, and that they are basing decisions in the region of the criterion band on information extracted from the sequence of decisions presented to them. The average bandwidth is generally different from the optimum bandwidth used by an ideal O in combining the two sources of information.
