Intergroup fairness and bias in children

In recent years in research on intergroup relationships, the assumption has increasingly been made that discrimination dominates decisions when individuals allocate resources between (members of) own and other group. Conversely, in empirical studies of interpersonal decision-making, including an extensive literature on the development of children's allocation rules within dyadic relationships, it has been repeatedly observed that in dyadic relationships choices though responsive to various changes in the environment, are more strongly governed by fairness rules. The present research extends the interpersonal fairness paradigm to the intergroup case, and examines the effects of some of those variables, namely, children's age, input and attitudes toward other, that have been observed to influence choice behaviour within interpersonal relationships. The findings indicate that as children are socialized, fairness rules also play an increasing dominant role in intergroup allocation decisions, and that both relative input and the language of the outgroup influence such decisions. At the same time, there is some preliminary evidence to indicate that the relative strength of self-interest may be somewhat stronger in intergroup than in interpersonal relationships. Finally, a number of the issues that must be confronted in comparing the two more important forms of human social choices, interpersonal and intergroup decision-making, are considered.     

The effects of commitment to threats and promises upon bargaining behaviour and outcomes

The course of bargaining is determined in part by interdependent individuals exchanging messages so as to influence other's behaviour, and thereby to increase the likelihood of achieving outcomes consistent with their own goals. The communication of threats and promises are two major message strategies that are employed to influence the behaviour of others in a bargaining relationship. The present study examines the effects of players' level of commitment to these forms of message strategies upon behaviour in a duopoly bargaining task. Past research has oprationalized commitment in terms of the consistency with which an individual has followed through on threats or promises in the past. In the present research, Becker's (1960) concept of a side-bet is employed to provide an alternative means for defining and manipulating commitment. A side-bet obtains when either a threatener or a promiser posts a valued resource, say a bond, which they forfeit if they do not follow through on their stated threat or promise. The main expectations of the present study were that increased commitment to threat meassages would lead to more competitive behaviour and outcomes within a duopoly bargaining task, whereas increased commitment to promise messages would produce more cooperative behaviour and outcomes. Partial support for these major expectations, as well as confirmation of a number of secondary expectations, was obtained.     

SOCIETAL MEMBERSHIP,SCORE STATUS,AND GAME BEHAVIOR

Appartenance sociale, bilan relatif des gains acquis et comportement de jeu. Analyse phénoménologique. — Etude des preférénces, des raisons et du comportement reel de choix de sujets belges et américains dans une tâche qui laisse la possibilité de se comporter coopérativement ou compétitivement. La tâche utilisée est un jeu à somme non-nulle dont la matrice est structuréd de telle sorte que l'on puisse différencier deux objectifs parmi trois possibles : maximiser son propre gain (ou le gain conjoint des deux partenaires) ou bien maximiser la différence entre son propre gain et celui de l'autre. Les Auteurs ont comparé 15 dyades de sujets belges et 15 dyades de sujets américains, jouant en 100 essais. Les résultats montrent que le choix réel des sujets est trés semblable d'une culture à l'autre et que, dans chaque culture, il varie selon que les gains déjà acquis par un sujet sont supérieurs, inférieurs ou égaux à ceux du partenaire, au moment du choix. Enfin, on note que, bien qu'aucune différence marquée n'apparaisse dans le comportement réel, il y a des différences sensibles d'une culture à l'autre dans les raisons invoquées par les sujets pour justifier leurs préférences : ces différences sont encore plus apparentes si on tient également compte de l'état relatif des gains déjà acquis par un sujet par rapport à son partenaire. En général, les sujets belges ont tendance à justifier leur préférence pour la compétition par des raisons de compétition; les sujets américains, surtout quand ils ont l'avantage, par des raisons relatives à leur gain personnel. Cette dernière réaction est “irrationnelle” dans la présente tâche puisque la préférence pour une attitude coopérative permet de maximiser son propre gain.     

Assessing Adolescent and Adult Attachment: A Review of Current Self-Report Measures

Increased interest in attachment theory among counseling researchers and practitioners has led to the development of several measures of attachment-related constructs. Following a brief overview of the theoretical foundations of attachment theory as conceptualized by Ainsworth (1989) and Bowlby (1988), the authors of this article review four self-report measures of adolescent and adult attachment. Many considerations for the selection and use of these instruments in future counseling research and assessment are discussed.     

Colour vision,evolution, and perceptual content

Computational models of colour vision assume that the biological function of colour vision is to detect surface reflectance. Some philosophers invoke these models as a basis for externalism about perceptual content (content is distal) and objectivism about colour (colour is surface reflectance). In an earlier article (Thompson et al. 1992), I criticised the computational objectivist position on the basis of comparative colour vision: There are fundamental differences among the colour vision of animals and these differences do not converge on the detection of any single type of environmental property. David R. Hilbert (1992) has recently defended computational objectivism against my comparative argument; his arguments are based on the externalist approach to perceptual content originally developed by Mohan Matthen (1988) and on the computationally inspired theory of the evolutionary basis for trichromacy developed by Roger N. Shepard (1990). The present article provides a reply to Hilbert with extensive criticism of both Matthen's and Shepard's theories. I argue that the biological function of colour vision is not to detect surface reflectance, but to provide a set of perceptual categories that can apply to objects in a stable way in a variety of conditions. Comparative research indicates that both the perceptual categories and the distal stimuli will differ according to the animal and its visual ecology, therefore externalism and objectivism must be rejected.Versions of this article were read to the Department of Philosophy at the University of Chicago and to the Department of Philosophy at Boston University. I am grateful to the audiences for the discussions that ensued. I am also grateful to an anonymous referee for constructive criticism of certain points in the article. Special thanks are due to my comparative colour vision collaborators, Adrian Palacios and Francisco Varela.     

“My big sister the town supervisor”: Family leadership training is not just for boys

This study investigates gender similarity in the effects of birth order upon political leadership. Town supervisors were the leaders studied as there are a considerable number of women who attain this level of leadership. Questionnaires about birth order and family size were gained from 66 women who were town supervisors in New York State in 1992, and compared to a randomly selected sample of 57 male town supervisors. It was found that women as well as men town supervisors were more likely to have been first born in their families. However, whereas gender does not apparently influence the relevance of birth order for leadership, it clearly does exert an influence on the level of political leadership attained. Women town supervisors gained their positions in towns that were considerably smaller than the towns led by the male supervisors. Discussion concerned the nature of family experiences that contribute to leadership training, including those that may be different for girls and boys. Further research is needed to clarify barriers to female assertion of political leadership at more senior levels, because as this study shows, female leadership is being trained in families.
