Measures of attitudinal polarization

Abstract.— Criteria for measures of attitudinal polarization, i. e., degree of opposition among people on a specific issue, are proposed and some formulas, including the standard deviation, are evaluated in relation to the criteria. The formulas were also tested on empirical data with respect to level, dispersion and agreement of received values. The measures on the whole showed a high degree of agreement. There clearly exist instances where the standard deviation is not an adequate measure of attitudinal polarization. Some guidelines are given for the choice of constant values in one of the formulas.     

The multidimensionality of state and trait anxiety

Abstract.— The two major problems investigated were ( a ) the multidimensionality of trait (A-Trait) and state (A-State) anxiety, and ( b ) the relationship between A-Trait and A-State under neutral conditions, using two measures of A-Trait (SR-GTA and STAI-T) and two measures of A-State (BRQ and STAI-S). These scales were administered to a sample of Swedish university students (54 males and 105 females). Factor analyses of the GTA situational scales yielded an interpersonal ego threat A-Trait factor and a physical danger A-Trait factor. Factor analyses of the GTA reaction scales and STAI-T reaction scales yielded, respectively, two and three factors providing evidence for the multidimensionality of A-Trait. Results of variance components analyses of the GTA scales provided further evidence for the multidimensionality of A-Trait. Factor analyses of the BRQand STAI-S measures yielded four and three factors, respectively, indicating the multidimensionality of A-State. The correlations between trait and state measures were higher than the correlations between the two state measures, and a factor analysis of the trait and state scales did not yield separate state and trait factors, questioning the proposition that A-Trait and A-State are distinct concepts. Via latent profile analysis, it was possible to compare A-State differences for different A-Trait profiles. Problems for further research were discussed.

A method for analysing performance in the rod-and-frame test. II Test of the Statistical Model

Abstract.— A new method of scoring the Rod-and-Frame Test (RFT) has been proposed (Nyborg, 1974). The statistical model behind the new method is introduced and tested in the present work.

In defence of the criticism of the Defence Mechanism Test (DMT): A reply to Kragh (1998)

Kragh ( Scandinavian Journal of Psychology , 1998, 39, 123–124) criticises a recent empirical study of the Defence Mechanism Test (DMT) conducted by the present authors (Zuber & Ekehammar, 1997) concerning methodological and other shortcomings. The present paper reviews and responds to Kragh's critical points. As to the most serious criticism, the methodological, the main conclusion is that Kragh's own published empirical studies of the DMT, and also those of other researchers, can be criticised along similar lines. Furthermore, and surprisingly, in contrast to our study, Kragh's main DMT studies do not employ the DMT picture(s) at all.     

Cognitive processes among skilled miniature golf players: Effects of instructions on motor performance, concentration time, and perceived difficulty

Highly skilled miniature golf players were examined on a simplified miniature golf task under different instructional conditions. Results indicated that requirements to attend to a variety of technical aspects of the game during preparation impaired motor performance, whereas providing players with those aspects of the game they reported thinking of did not affect motor performance. Data on concentration time and perceived difficulty indicated that increasing cognitive demands were associated with a decline in motor precision. The overall pattern of results was interpreted such that attention directed at technical aspects of the game interfered with the players' normal cognitive activity. Susceptibility to interference is a characteristic feature of controlled cognitive operations. Thus, the present results are consistent with the view that conscious cognitive activity may support motor behavior also at late stages of skill development.     

The Sociomoral Reflection Measure: Applicability to Swedish children and adolescents

The Sociomoral Reflection Measure (SRM; Gibbs & Widaman, 1982) was developed as a group administerable instrument for measuring developmental stages of moral reasoning. The aim of this study was to examine its reliability and construct validity, employing a sample of 542 Swedish elementary and high school students (aged 8-17), from schools within metropolitan Stockholm. Interrater reliability varied between 0.83 and 0.92, and the internal consistency coefficient was 0.76. Factor analyses of the norms (on which the overall score is based) revealed one factor for the oldest age group (16-17 years), but two factors among the younger subjects (8-15 years), clearly separating the norms related to each of the two moral dilemmas. The Sociomoral Reflection Maturity Score was moderately, but significantly, related to both age and grade. The results suggests that, although used in a non-American context and with self-trained raters, the SRM seems highly applicable in Sweden, at least for research purposes.     

Effects of standard modality, comparison modality and retention interval on matching of form

Garvill, J. & Molander, B. Effects of standard modality, comparison modality and retention interval on matching of form. Scand. J. Psychol., 1973, 14, 203–206.MdashIntra-modal and cross-modal matching of nonsense forms was studied in a 2 (standard modalities: visual vs. tactual) by 2 (comparison modalities: visual vs. tactual) by 3 (intervals between standard and comparison: 1, 10 and 30 sec) factorial experiment. The errors were divided into false negatives and false positives. Significant effects of standard modality and of comparison modality were found for false negatives. For false positives the most prominent effect was an interaction between the standard modality and the comparison modality. Retention interval had no effect in any of the modality conditions. The effects are discussed in terms of differential information processing capacity for the visual and the tactual modalities.
