Fairness and bargaining power in threshold public goods experiments

Experiments on three two‐person threshold public good provision games, namely, the simultaneous, sequential, and dictator games, are conducted to explore the motives behind giving. Players who move simultaneously are endowed with equal bargaining power, and players who move first are endowed with more bargaining power than players who move subsequently. Dictators are indubitably endowed with complete bargaining power. Since the differences between the bargaining powers of two players increase from the simultaneous to the sequential to the dictator game, comparisons among games allow us to trace whether the contribution behavior is motivated by fairness or is simply due to the strategic concern. The experimental evidence shows that the strategic concern explains the overall contribution behavior better than the motive of fairness. However, in the final round 26% of the dictators share the threshold evenly with their opponents, suggesting that some subjects do play fairly. Copyright © 2007 John Wiley & Sons, Ltd.     

Arguing ‘for’ the Patient: Informed Consent and Strategic Maneuvering in Doctor–Patient Interaction

As a way to advance integration between traditional readings of the medical encounter and argumentation theory, this article conceptualizes the doctor–patient interaction as a form of info-suasive dialogue. Firstly, the article explores the relevance of argumentation in the medical encounter in connection with the process of informed consent. Secondly, it discloses the risks inherent to a lack of reconciliation of the dialectical and rhetorical components in the delivery of the doctor’s advice, as especially resulting from the less than ideal conditions of the internal states of the doctor and the patient, and the lack of symmetry in their status.     

Dissolving the diaspora: Dialogical practice in the development of deep multiculturalism

This article is an exposition of deep or critical multiculturalism that is grounded in a mutually respectful dialogue. Such multiculturalism names historical oppressions, recognizes the structural causes of injustice and inequality, and is profoundly open to cultural critique, challenge and change. In order to promote such a multicultural practice, the article makes the case for a dialogical politics of deep and mutual respect in which ethno‐religious sensibilities are validated and welcomed in their rich diversity. In doing so, the article draws upon the author's empirical research on the Muslim minority in contemporary Canada. Copyright © 2008 John Wiley & Sons, Ltd.     

Mechanical restraints as positive reinforcers for aggression

Research suggests that, in some cases, mechanical restraints may function as positive reinforcers. In this study, we conducted a functional analysis of severe aggression exhibited by an individual with a history of wearing arm splints. The results of this functional analysis demonstrated that his aggression was maintained by access to the arm splints. Copyright © 2008 John Wiley & Sons, Ltd.     

Visual statistical decisions

To identify variables that underlie intuitive judgments about the sizes of groups of similar objects, we asked people to judge the relative heights of vertical bars briefly shown, two groups at a time, on a computer display. Randomly selected normal deviates determined individual bar height. Average differences in height and group sizes were also randomly varied. Twenty-eight participants judged 250 differences each, which were then submitted to multiple regression analysis and psychophysical inspection. The total number of bars sharpened discrimination, whereas variance dulled it. Critical ratio (CR), the forerunner to the modern t test, emerged as the most important predictor, little additional variance was explained by other factors. The difference in the number of bars was a reliable factor, favoring the greater number of bars. Confidence limits around thresholds, defined as CRs needed to say "possibly greater" surrounded 1.65; as a z value, this corresponded to a one-tailed probability of .05. Judgments about noisy stimuli thus seem to be based on a statistical process and to employ a probability criterion similar to that used in the formal statistical evaluation of experimental findings--namely, p < .05.     

Does subjective well-being show a relationship between parents and their children?

The relationship between the subjective well-being of parents and their own 12–16-year-old children was explored in a Spanish sample of N = 266 families. A positive relationship was expected due to both a shared environment and the possibility of the genetic transmission of subjective well-being ‘set-points’. A positive significant relationship was found for the summated scale of satisfaction domains forming the Personal Well-being Index, and for the specific domains of health and security for the future. However, no relationship was found for the other five domains that make up this Index or for satisfaction with life as a whole. We conclude while these results provide some evidence for the expected influence of a shared environment, they have failed to provide evidence for high heritability of set-points for subjective well-being.     

Experimental analysis of preschool playmate preferences as a function of smiles and sex

Differential emotions theory (DET) (The face of emotion. Appleton‐Century‐Crofts: East Norwalk, CT, 1971) posits that the smile functions in part to communicate and/or reflect social affiliation and plays an important role in children's social development. While children's positive emotion expressions have received attention from peer relations researchers in observational studies and within correlational designs, there is almost no experimental evidence for the impact of the smile. Building on existing studies, the present study examined DET predictions within an experimental design. More specifically, we examined the impact smiles have on lower‐income preschool children's nominations for preferred playmates. Both boys and girls tended to nominate unfamiliar playmates who smiled. Additionally, some evidence suggested that preference for smiling playmates seemed more critical to girls' than boys' social functioning. Unlike among boys, teachers rated girls who exhibited a greater preference for smiling playmates as higher in social competence. Copyright © 2008 John Wiley & Sons, Ltd.     

Associations between mothers' sensitivity to their infants' internal states and children's later understanding of mind and emotion

This study investigated associations between mother–infant interactions and children's subsequent understanding of mind and emotion. Mothers' tendency to comment on their infants' internal world and their general sensitivity to their infants' internal states were measured through coded play interactions at 10 months. The latter measurement included ratings on four aspects of maternal behaviour: mindful facilitation, joint attention commenting, pacing, and affect catching. In contrast to mothers' internal state language, these behaviours did not tap mothers' explicit linguistic representation of their infants' mental states. At 54 months, children's understanding of mind and emotion was measured through a range of false‐belief tasks and an emotion‐understanding task. Multivariate analysis revealed direct positive links between mothers' sensitivity to their infants' internal states and children's later understanding of mind.

The dominance of fear over hope in the life of individuals and collectives

We address the question why fear dominates hope in the life of individuals and collectives on the basis of the accumulated knowledge in the psychology, neurology and sociology of emotions. This knowledge suggests that fear, as primary emotion, is grounded in the experienced present and based on the memorized past, processed both consciously and unconsciously, causes freezing and conservatism, and sometimes leads to pre‐emptive aggression. Hope, in contrast, as a secondary emotion, involves cognitive activity, which requires anticipation and the search for new ideas and thus is based on complex processes of creativity and flexibility. Therefore, hope is often preceded and inhibited by spontaneous, automatically activated and faster fear. Fear and hope can each become a collective emotional orientation, and as such organize society's views and direct its actions. Societies involved in intractable conflict are dominated by a collective fear orientation. This orientation is functional for society's coping with the stressful and demanding situation—but it may serve as a psychological obstacle to any peace process, once it starts. The case of the collective fear orientation in the Jewish Israeli society is presented as an example. The article ends with a presentation of a particular approach, suggesting that individuals and collectives can overcome their fear with much determination, and establish an orientation of hope which allows change in situations dominated by fear.
