Communicative gestures of the hand and arm when 4-year-old sons and their mothers interact

This study investigated a wide range of communicative hand/arm gestures of 4-year-old males when interacting with their mothers. The types of gesture categories observed were in keeping with the predicted encoding ability of this aged child. Pantomimic and deictic gestures were observed in significantly greater numbers than semantic modifying and relational gestures. Although it was found that the mothers' gestural usage reflected the type of gesture categories seen in the children's group, no correlation was found between gesture usage of individual mother-child pairs.     

The demonstration of capacity limitation

The study of divided attention has produced many apparent demonstrations of “capacity limitation.” Possible ambiguities in such demonstrations are considered for three major types of experimental situation: simultaneous inputs with separate responses; choice; and classification. Two issues emerge. First, demonstrations always rest on assumptions about process set, i.e., the set of internal processes by which the task actually is performed. Alternative process sets are considered for situations of each type. Second, a demonstration of capacity limitation is made either by increasing the number of simultaneous processes, or by changing the bias between them. In either case effects unrelated to capacity limitation may influence the results. If several processes contribute to a single response, some performance decrement must accompany an increase in their number, simply through the increased overall chance for error. If the subject is biased toward one alternative in a choice or classification situation, the benefits enjoyed by this alternative may reflect not a preferential allocation of attentional capacity, but simply a willingness to decide in favor of this alternative with relatively little evidence.     

Selective exposure to information and cognitive dissonance

Despite numerous attempts, the selective exposure prediction of Festinger's (A theory of cognitive dissonance. Evanston, Ill.: Row, Peterson, 1957) theory of cognitive dissonance has not been consistently demonstrated. In previous studies, this failure can be attributed to design deficiencies, and other related problems. The present study manipulated dissonance by having subjects write a counterattitudinal essay under conditions of high or low choice. Information in the form of pamphlets and discussion groups was offered to the subjects such that they could choose information that was consonant and dissonant with the decision to write the essay. The information was offered either before or after an attitude measure on the essay topic, as the attitude measure could also be a source of dissonance reduction. The results indicate that the high choice manipulation yielded greater attitude change than the low-choice manipulation. High-choice subjects desired consonant information more and dissonant information less than did low-choice subjects. This effect was found for both measures of information desire (pamphlets and discussion groups). Low-choice subjects who received the attitude questionnaire before the information measures wanted information more than if offered the information before the attitude questionnaire, implying a sensitizing effect produced by the attitude questionnaire for the low-choice subjects. The various effects are discussed as providing support for predictions from Festinger's dissonance theory.     

Subjective utility,anticipated utility,and the Allais paradox

One of the most notable counterexamples to expected utility theory is the “Allais paradox” (M. Allais, 1953, Econometrica, 31, 503–546). A number of alternative theories have been proposed in an attempt to resolve this paradox, notably including Karmarkar, 1978, Karmarkar, 1979, 24, 67–72). It is shown that SWU theory necessarily involves violations of dominance, but that the theory can be modified to avoid these violations. The result is a special case of J. Quiggin's anticipated utility theory (1982, Journal of Economic Behaviour and Organisation, 3, 323–343).     

Similarity of attitudes and constructs in children's friendships

Sex prejudice in children's friendships has frequently been noted. This study examined the role of similarity of attitudes and personal construct ratings in this effect. Subjects were two classes of school children, aged 7–8 and 9–10 years. There were 29 children in each class. Subjects completed an attitude scale, construct rating scale, and sociometric questionnaire. Similarity effects were primarily in the younger children. Boys were more similar to each other in attitudes than were girls, and girls were more similar to each other in construct ratings than were boys (p < .001); there was greater similarity of attitudes and construct ratings in friendship rather than nonfriendship comparison dyads (p < .01). The sociometric data, when compared with sociometric data collected 6 months earlier, showed that these results could not be due to sex differences in the stability of friendships but rather suggested age and sex differences in the informational bases of friendships in middle childhood.     

The Motherhood of the Church in Henri de Lubac and John Calvin

Both Henri de Lubac and John Calvin described the Church as ‘mother’. From the patristic tradition, the motherhood of the Church had two dimensions: (i) the Mother Church as an institution delimited by the episcopacy of which inclusion was a necessity for salvation; and (ii) the Church as the mother of believers through whose ‘motherly’ care of bringing to life, nourishing and teaching through the sacraments God makes provision for his children. Both de Lubac and Calvin stress the maternal functions of the Church, but differ over how the Church’s motherhood relates to its visible identity and why inclusion in the Church is necessary for salvation. This article argues that this connection represents a rich theme for ecumenical ecclesiology. Despite divergent ecclesiological grammars and themes, Catholic and Reformed traditions are drawing from a shared patristic inheritance which gives good ground for dialogue for respective ecclesial self-understandings.     

Successful aging: Social theory,scripture, church teaching

ABSTRACT

Thanks to medical progress and better overall living conditions, a greater number of people are living well into old age, many more than in previous generations. However, we feel instinctively that there must be more to life than longevity and merely living longer. Religious communities and social scientists are both interested in what makes for “successful aging.” The dialogue between them can be enriched by fostering a mutual appreciation for biblical norms and stories, and a better working knowledge of the models and methods of the social sciences. To that end, I offer a sketch of four models of aging: disengagement, activity, continuity, and Tornstam’s theory of gerotranscendence. This sketch serves as a prelude to a discussion of three biblical stories: (1) the story of Barzillai and King David in 2 Samuel, which shows how the elderly can make a positive contribution to the common good, in spite of their limitations; (2) the intertwined stories of Jacob and Joseph in Genesis, which can help us understand the theological significance of life review, forgiveness, reconciliation, and life review in the aging process; and (3) the third phase of the encounter considers John Paul II’s Letter to the Elderly, and builds on several suggestions he makes concerning the life of Moses and successful aging.     

The Limits of Reproductive Decisions

In this article I will address the question of determining the moral limits of reproductive decisions. In so doing I will examine the contributions made by John Harris, who has over the years consistently addressed the ethical implications of advancing reproductive technologies. In addressing these matters, Harris has centred his arguments on the principle of harm and with this in mind has set out a specific theoretical framework from which decisions about disability and causing harm, as in the case of reproductive decisions, can be rationally addressed. This discussion will attempt to question the conceptual scheme that he proposes. The aim here is not to present an alternative theoretical contribution to the morality of reproductive choice. Rather, in the attempt to follow some of the directives in Wittgenstein’s later philosophy, the aim is to demonstrate some of the pitfalls of what Wittgenstein has described as the “craving for generality” in contemporary philosophy. I propose that this craving can distort, in this instance, our ordinary usage of concepts such as harm, suffering and disability and their role in the moral vocabulary of reproductive decision making
