Measuring social problem solving using the Spanish version for Hispanics of the Social Problem Solving Inventory-Revised

This study investigated the internal consistency, factor structure, and concurrent validity of the Social Problem Solving Inventory-Spanish Version for Hispanics (SPSI-R-Hispanic), a translation of the Social Problem Solving Inventory-Revised (SPSI-R; D'Zurilla, Nezu & Maydeu-Olivares, 2002), in a North American sample of 325 Spanish speaking Hispanics. The scales of the SPSI-R-Hispanic demonstrated good internal consistency reliability. The hypothesized factor model of the SPSI-R provided a good fit to the data. SPSI-R-Hispanic scores demonstrated concurrent validity in a multiple regression analysis, explaining 32% of incremental variability in psychological well-being scores. Gender differences were replicated, where men had higher positive problem orientation and rational problem solving scores and women had higher negative problem orientation scores.     

Can the Decoherence Approach Help to Solve the Measurement Problem?

This work examines whether the environmentally-induced decoherence approach in quantum mechanics brings us any closer to solving the measurement problem, and whether it contributes to the elimination of subjectivism in quantum theory. A distinction is made between ,collapse, and ,decoherence,, so that an explanation for decoherence does not imply an explanation for collapse. After an overview of the measurement problem and of the open-systems paradigm, we argue that taking a partial trace is equivalent to applying the projection postulate. A criticism of Zurek's decoherence approach to measurements is also made, based on the restriction that he must impose on the interaction between apparatus and environment. We then analyze the element of subjectivity involved in establishing the boundary between system and environment, and criticize the incorporation of Everett's branching of memory records into the decoherence research program. Sticking to this program, we end by sketching a proposal for ‘environmentally-induced collapse’. This revised version was published online in June 2006 with corrections to the Cover Date.     

Random error reduction in analytic hierarchies: a comparison of holistic and decompositional decision strategies

The principle of ‘divide and conquer’ (DAC) suggests that complex decision problems should be decomposed into smaller, more manageable parts, and that these parts should be logically aggregated to derive an overall value for each alternative. Decompositional procedures have been contrasted with holistic evaluations that require decision makers to simultaneously consider all the relevant attributes of the alternatives under consideration (Fischer, 1977 ). One area where decompositional procedures have a clear advantage over holistic procedures is in the reduction of random error (Ravinder, 1992 ; Ravinder and Kleinmuntz, 1991 ; Kleinmuntz, 1990 ). Adopting the framework originally developed by Ravinder and colleagues, this paper details the results of a study of the random error variances associated with another popular multi‐criteria decision‐making technique, the Analytic Hierarchy Process (AHP); (Saaty, 1977 , 1980 ), as well as the random error variances of a holistic version of the Analytic Hierarchy Process (Jensen, 1983 ). In addition, data concerning various psychometric properties (e.g. the convergent validity and temporal stability) and values of AHP inconsistency are reported for both the decompositional and holistic evaluations. The results of the study show that the Ravinder and Kleinmuntz ( 1991 ) error‐propagation framework extends to the AHP and decompositional AHP judgments are more consistent than their holistic counterparts.

The factor structure of the Need for Cognition Short Form in a Hispanic sample

The authors conducted a series of studies to validate the factor structure of the English version of the Need for Cognition-Short Form (NFC-SF; J. T. Cacioppo, R. E. Petty, & C. F. Kao, 1984) in a U.S. Hispanic sample. Study 1 is an exploration of the factor structure in 238 Hispanic and relationships between gender and acculturation. Analyses in Study 2 confirmed the factor structure from the sample in Study 1 in a group of 185 U.S. Hispanics. Results indicated that the English version of the NCS-SF has a one-factor structure and is reliable for use with U.S. Hispanics.     

The assessment of factorial invariance in need for cognition using Hispanic and Anglo samples

The Need for Cognition Scale-Short Form (NCS-SF; J. T. Cacioppo, R. E. Petty, & C. F. Kao, 1984) is a commonly administered measure in the behavioral sciences, but little research has assessed its applicability across cultures. A sample of undergraduates in the southeastern United States and a sample of undergraduates at a southwestern U.S. university completed the NCS-SE Hispanic respondents did not differ from Anglos in their mean NCS-SF scores. Confirmatory factor analysis revealed that factor parameter estimates and item intercepts were partially measurement invariant across samples.     

Determinants of perceived surface transparency in two-dimensional achromatic textured patterns

Achromatic transparency in 2-D surfaces composed of three adjacent areas, one created from the others, occurs when in the created area it is possible to see the two colours of the adjacent areas. Displays with two white and black intersecting bars were produced to verify the possibility of perceiving transparency in the intersection area when this was subdivided into a different number of white and black diamonds. By increasing the spatial frequency of the elements in the intersection area we investigated the impression of transparency, and found that (i) the impression of transparency increases up to a spatial frequency of 10 cycles deg(-1) and then levels off, (ii) there is a transition from a perception of transparency in which white and black are well discriminable to a perception in which a perceptually uniform grey is seen, (iii) the perception of transparency occurring when colours are discriminated seems consistent with Helson's area-luminance hypothesis [1964, in Adaptation Level Theory (New York: Harper & Row) pp 282-292], according to which the increase of spatial frequency determines the transition from the phenomenon of contrast to that of assimilation.
