Meaning and Truth-Conditions: a Reply to Kemp

In his 'Meaning and Truth-Conditions', Gary Kemp offers a reconstruction of Frege's infamous 'regress argument', which purports to rely only upon the premises that the meaning of a sentence is its truth-condition and that each sentence expresses a unique proposition. If cogent, the argument would show that only someone who accepts a form of semantic holism can use the notion of truth to explain that of meaning. I respond that Kemp relies heavily upon what he himself styles 'a literal, rather wooden' understanding of truth-conditions. I explore alternatives, and say a few words about how Frege's regress argument might best be understood.     

Personality,gender, and crying

This study examined gender differences in crying as well as associations between basic personality traits and self‐reported indices of crying. Forty‐eight men and 56 women completed the Five‐Factor Personality Inventory and the Adult Crying Inventory. Substantial gender differences were demonstrated in crying frequency and crying proneness, but not with respect to mood changes after crying. As predicted, women reported a higher frequency of crying and more proneness to cry both for negative and positive reasons. For women, all these crying indices were negatively associated with Emotional Stability. For men, only a significant negative relationship between Emotional Stability and crying for negative reasons emerged. No clear links were found between personality and mood changes after crying. Multiple regression analysis revealed a significant predictive role of gender for crying proneness, even when controlling for personality differences, but not for crying frequency. Adding personality by gender interaction terms resulted in a disappearance of the main effect of sex, while significant interactions with personality factors showed up for crying frequency and general crying proneness. It is suggested that future research on the relationship between personality and crying should focus more on the underlying mechanisms of observed relationships. Furthermore, it is recommended that future research should examine the role of different emotion regulation strategies. In addition, biological factors, temperament, upbringing measures, and socio‐demographic variables should be taken into account. Copyright © 2001 John Wiley & Sons, Ltd.     

Religious renewal in Syria: the case of Muammad al‐abash

The Syrian Muammad al‐abash, member of the religious establishment and recently elected to parliament, is the leading figure in a movement of religious renewal in Syria. The Islamic vision he has articulated sheds light not only on the existence of a dynamic religious and inter‐religious debate currently taking place in Syria but also on the potential role of Islam in the development of a civil society in Syria that brooks room in the public arena for both the religious and the secular.     

Generalized Processing Tree Models: Jointly Modeling Discrete and Continuous Variables

Multinomial processing tree models assume that discrete cognitive states determine observed response frequencies. Generalized processing tree (GPT) models extend this conceptual framework to continuous variables such as response times, process-tracing measures, or neurophysiological variables. GPT models assume finite-mixture distributions, with weights determined by a processing tree structure, and continuous components modeled by parameterized distributions such as Gaussians with separate or shared parameters across states. We discuss identifiability, parameter estimation, model testing, a modeling syntax, and the improved precision of GPT estimates. Finally, a GPT version of the feature comparison model of semantic categorization is applied to computer-mouse trajectories.     

Detecting nonadherence without loss in efficiency: A simple extension of the crosswise model

In surveys concerning sensitive behavior or attitudes, respondents often do not answer truthfully, because of social desirability bias. To elicit more honest responding, the randomized-response (RR) technique aims at increasing perceived and actual anonymity by prompting respondents to answer with a randomly modified and thus uninformative response. In the crosswise model, as a particularly promising variant of the RR, this is achieved by adding a second, nonsensitive question and by prompting respondents to answer both questions jointly. Despite increased privacy protection and empirically higher prevalence estimates of socially undesirable behaviors, evidence also suggests that some respondents might still not adhere to the instructions, in turn leading to questionable results. Herein we propose an extension of the crosswise model (ECWM) that makes it possible to detect several types of response biases with adequate power in realistic sample sizes. Importantly, the ECWM allows for testing the validity of the model’s assumptions without any loss in statistical efficiency. Finally, we provide an empirical example supporting the usefulness of the ECWM.     

Cortisol and behavioral reaction of low and high sensation seekers differ in responding to a sport-specific stressor

Background/objectives: Sensation seeking is closely related to practicing high-risk sports. This domain offers individuals an opportunity to achieve an increased level of arousal. Moreover, stress reactivity implies interindividual differences in the capacity to respond to a stressor. The purpose of this study was to examine whether high sensation seekers (HSS) compared to low sensation seekers (LSS) experience lower levels of stress on a physiological and psychological basis. Stress was induced in a sport-specific experimental paradigm with a climbing task through a jump into the rope.

Methods: Two extreme groups (n?=?28 male athletes) were examined in a mixed-factorial design (between: HSS vs. LSS; within: repeated measurements of several variables related to stress reactivity - cortisol, heart rate, anxiety).

Results: In response to the stressor HSS compared to LSS released a significantly lower amount of cortisol and needed less time for the climbing task. Heart rate and anxiety were not significant.

Conclusions: Individuals seem to react physiologically differently to a sport-specific stressor, depending on their level of sensation seeking. HSS seem to be less strained, and seem to perform better. These findings might be relevant not only for the evaluation of (sport-) psychological interventions but also for other contexts (e.g., special forces).

Social game theory: Preferences,perceptions, and choices

ABSTRACT

Building on classic game theory, psychologists have explored the effects of social preferences and expectations on strategic behaviour. Ordinary social perceivers are sensitive to additional contextual factors not addressed by game theory and its recent psychological extensions. We review the results of a research programme exploring how observers judge “players” (i.e., individuals making strategic decisions in social dilemmas) on the dimensions of competence and morality. We explore social perception in several well-known dilemmas, including the prisoner’s dilemma, the volunteer’s dilemma, and the trust dilemma. We also introduce a novel self-presentational dilemma. In research conducted over a decade and a half, we have found that judgements of competence are sensitive to both players’ choices and the dilemma’s (expected and actual) outcomes. In contrast, judgements of morality respond strongly to players’ behaviour and little else. We discuss how these social-perceptual patterns might affect expectations, preferences, and strategic choices.
