The big carrot: High‐stakes incentives revisited

Using an international dataset of about 35 000 subjects, this paper provides an empirical example of high‐stakes incentives in relation to religious practice. First, we show that incentives (based on absolute belief) play a salient role in religious performance. Second, we find that when both positive (heaven) and negative (hell) incentives are available the former are more effective than the latter. Specifically, it is shown that beliefs in heaven are much more relevant than beliefs in hell when estimating the production of religious commodities (church‐attendance and praying equations).

An empirical test of two opposing theoretical models of prefrontal function.

The purpose of this study was to compare the validity of two models which contrast with each other in the manner in which they integrate neuropsychological tests into distinct prefrontal constructs. The first prefrontal model consists of five distinct functional constructs drawn from human clinical neuropsychology. The second model, elaborated by Goldman-Rakic, is based primarily on monkey research and postulates a basic prefrontal function, "on-line representational memory," which guides behavior in the absence of, or despite discriminative environmental stimuli. In the latter model, distinct prefrontal functional constructs are primarily defined in terms of various types of representational memory involved in specific tasks. Eleven "prefrontal" measures were obtained from 259 normal adults, stratified for age, education, and sex. Confirmatory factor analyses revealed that the Goldman-Rakic model "fit" the data better than the model derived from human clinical neuropsychology, while several constructs commonly used in human neuropsychology were refuted. It was concluded that new research on brain-damaged humans with a view to understanding prefrontal function might benefit from using the Goldman-Rakic model as a starting point.     

Cross-cultural validity, reliability, and stimulus characteristics of the Lüscher Color Test

The Lüscher Color Test (LCT) was administered to 125 Canadian university students, 88 of whom were retested 21 days later. Sample and sex-specific color preferences were found as well as discrepancies between Lüscher's color-naming system and two widely used color-naming systems. Test-retest reliability estimates were low. It was concluded that the LCT suffers from major shortcomings and that research investigating the relationship between color preference and personality should follow alternate paths.     

Relationship between perceived health care quality and attitude toward substance abuse treatment

Despite the considerable investment made in recent years in Spain in substance abuse care, treatment adherence remains one of the aspects that determine the effectiveness of programs. Several authors have noted the importance of perceived service quality in this context. This paper is presented with dual purpose of highlighting the role that management of the quality of care for drug addicts has, both as a modulator of users' attitudes and perceptions about the treatment, and as a work philosophy, typical of an organization committed to continuous improvement. Conducting personal interviews with 670 users of drug abuse care services in Galicia and through the application of covariance structure analysis, the close relationship between two factors (perceived quality and attitude toward treatment) was revealed. This research also provides professionals and researchers with a new scale for service evaluation that is short, easy to use and with adequate psychometric properties.     

Proof-Theoretic Functional Completeness for the Hybrid Logics of Everywhere and Elsewhere

A hybrid logic is obtained by adding to an ordinary modal logic further expressive power in the form of a second sort of propositional symbols called nominals and by adding so-called satisfaction operators. In this paper we consider hybridized versions of S5 (“the logic of everywhere”) and the modal logic of inequality (“the logic of elsewhere”). We give natural deduction systems for the logics and we prove functional completeness results.     

Modal Logic,Truth, and the Master Modality

In the paper (Braüner, 2001) we gave a minimal condition for the existence of a homophonic theory of truth for a modal or tense logic. In the present paper we generalise this result to arbitrary modal logics and we also show that a modal logic permits the existence of a homophonic theory of truth if and only if it permits the definition of a so-called master modality. Moreover, we explore a connection between the master modality and hybrid logic: We show that if attention is restricted to bidirectional frames, then the expressive power of the master modality is exactly what is needed to translate the bounded fragment of first-order logic into hybrid logic in a truth preserving way. We believe that this throws new light on Arthur Prior's fourth grade tense logic.     

Social comparison and the drive upward revisited: Affiliation as a response to marital stress

To test theoretical ideas derived from classic and recent social comparison theory, two studies examined affiliative tendencies as a response to marital problems among individuals varying in marital dissatisfaction. Study 1 (n. = 632) showed that the higher the degree of marital dissatisfaction and the higher the uncertainty about how things are going in one's marriage, the stronger was the desire for affiliation (operationalized as the desire to talk with others about one's marriage). Moreover, among individuals high in marital dissatisfaction, a preference for upward affiliation was found, i.e. for contact with others having better marriages. Individuals with lower levels of dissatisfaction preferred affiliation with similar others. Women experienced more uncertainty and a stronger affiliative tendency than men. In Study 2 (n = 233), these findings were largely replicated. Moreover, it was shown that the desire to affiliate when facing marital stress was particularly strong among individuals high in interpersonal orientation.
