Long-term smoking intervention at the worksite: effects of quit-smoking groups and an "enriched milieu" on smoking cessation in adult white-collar employees

Maximizing the potential of worksites for smoking intervention remains elusive. We hypothesized that long-term effectiveness of group intervention would be enhanced when offered within an "enriched milieu" (full program) compared with relative isolation (group only). The data failed to support the hypothesis. Although sustained abstinence rates were higher at full-program sites (50%) than at group-only sites (44%), the difference did not achieve statistical significance. Initial (35% vs. 47%) and 12-month (18% vs. 22%) quit rates at full-program and group-only sites also failed to demonstrate the "benefit" of the "enriched milieu."     

Integration of information from multiple element displays

This experiment examined the processing of information from multiple element visual displays, using techniques derived from the theory of signal detectability. The method allows one to specify how observers integrate information from individual elements of a display. The experiment tested numerical and graphical displays having different display sizes, durations, and arrangements of elements. Observer performance increased with the number, m, of display elements, but at less than the ideal √m rate. Observer performance was consistent with a model of information integration constrained by internal noise. Linear arrays of elements resulted in better performance than did square arrays. Graphically coded elements resulted in better performance than did numerical elements. Observer decision weighting of element information from graphical displays was approximately uniform across spatial position, but the weighting of information from numerical displays was concentrated on elements near the fixation point.     

Personality diagnostic questionnaire-revised (PDQ-R) personality disorder scores and negative life events independently predict changes in hopkins symptom checklist (SCL-90) Psychopathology Scores

The present study employed a prospective design to investigate whether Personality Diagnostic Questionnaire—Revised (PDQ-R) scores and/or Hassles Scale—Revised (HS-R) scores predict changes in Axis I psychopathology levels over 1 month, in a nonclinical sample of young adults. The PDQ-R, HS-R, and Hopkins Symptom Checklist (SCL-90) were administered to a mixed-sex sample of 100 undergraduate students on two occasions separated by 1 month. Hierarchical multiple regression analyses indicated that (1) time 1 PDQ-R composite scores predicted changes in scores on 11 SLC-90 scales; (2) time 1 PDQ-R impairment/distress index scores predicted changes in SCL-90 general symptom index scores; (3) only one of the individual PDQ-R personality disorder subscales—the schizotypal personality disorder subscale—predicted changes in SCL-90 general symptom index scores; (4) HS-R scores predicted changes in scores on 9 SCL-90 scales; and (5) in only 3 of the 27 analyses conducted did the statistical interaction between PDQ-R and HS-R scores predict changes in SCL-90 scores. These findings indicate that personality disorder symptomatology and negative life events may independently predict changes in Axis I psychopathology levels and, thus, support the continued inclusion of Axis II and Axis IV in future versions of the Diagnostic and Statistical Manual of Mental Disorders.     

Determinants of satisfaction with specific job facets: A test of Locke's model

Survey results supported Locke's (1969, 1976) contention that facet job satisfaction is a function of three basic determinants: 1) facet amount; 2) wanted amount; and 3) facet importance. We found several three-way interactions that were generally consistent with Locke's model. Specifically, facet satisfaction was highest when employees wanted a large amount of the facet in question, were currently receiving a large amount, and felt that the facet was personally important. Conversely, satisfaction was lowest when employees wanted a large amount of the facet, were currently receiving only a small amount, and felt that the facet was personally important. When job facets were viewed as unimportant to employees, however, the amount of facet desired and currently possessed had little impact on satisfaction. Implications, limitations, and directions for research are discussed.Bob Rice passed away recently. He will be sorely missed.     

The examination of labels—a beginning

Unclear terminology is a major problem for the study of anomalies, and ambiguous definitions of reality and consciousness make it particularly difficult to discuss anomalous phenomena. Researchers have used the term near-death experience to describe four different kinds of incidents. To avoid confusion, we need new labels for experiences that differ in their relationship to death and near-death and in their transformative potential.     

Random error in additive decompositions of multiattribute utility

Decomposition is a common strategy for dealing with the complexity of multiattribute decision problems. A cognitively demanding task is broken down into tasks requiring simpler, perhaps easier, judgments which can then be aggregated. But individual judgments can be inconsistent in systematic or random fashion and when aggregated there is the possibility of propagation of this inconsistency. In this paper inconsistency in the form of random error is investigated in the context of additive decomposition of multiattribute utility. The process of aggregation of random error is studied and a comparison made with random error in holistic estimates of multiattribute utility. Conditions under which decomposition improves the consistency of the multiattribute utility estimate are presented and discussed.     

MULTIDIMENSIONAL SCALING OF LARGE CHROMATIC DIFFERENCES BY NORMAL AND COLOR-DEFICIENT SUBJECTS

The following two articles offer a glimpse at current experimental psychology in the Soviet Union, normally screened from the English-speaking world by all but impenetrable language barriers. The accompanying Commentary by Tarow Indow helps place these contributions in the framework of contemporary work on the psychophysics of color perception.   Abstract —
Fifteen normal trichromatic subjects, two protanopes, and two deuteranopes judged pairs of successively presented foveal color stimuli. Multidimensional scaling of the data yielded estimates of a three-dimensional space with axes interpreted as red–green, blue-yellow, and white-black. For color-deficient subjects, the average radius of the space differed from that of normals, being smaller for the protanopes and larger for the deuteranopes. For both types of color deficiency, the blue-yellow axis was stretched relative to the red-green, more strongly in the protanopes. The findings are taken to support the generality of a "spherical" model.     

THE INSTITUTE OF PSYCHOLOGY, USSR: A 20-Year Retrospective

The Institute of Psychology in Moscow became affiliated with the Academy of Sciences (AS USSR) 20 years ago. In this article a brief history of the Academy of Sciences and the Institute of Psychology is presented, along with a critical examination of the Institute's contribution to world psychology. Through an appraisal of laboratories, productivity, and journal articles, it is argued that Soviet psychologists affiliated with the Institute have made a modest impression on world psychology. The reason for the limited contribution is attributed to the lack of support from the Academy, the lack of essential equipment and supplies, the repressive political environment under which scientists have been forced to operate, and ethnocentrism brought about through cultural and physical isolation.
