Utilization of static and kinetic information for depth by young Malaŵians

The utilization of static and kinetic information for depth by Mala?ian children and young adults in making monocular relative size judgments was investigated. Subjects viewed pairs of objects or photographic slides of the same pairs and judged which was the larger of each pair. The sizes and positions of the objects were manipulated such that the more distant object subtended a visual angle equal to, 80% of, or 70% of the nearer object. Motor parallax information was manipulated by allowing or preventing head movement. All subjects displayed sensitivity to static information for depth when the two objects subtended equal visual angles. When the more distant object was larger but subtended a smaller visual angle than the nearer object, subjects tended to base their judgments on retinal size. Motion parallax information increased accuracy of judgments of three-dimensional displays but reduced accuracy of judgments of pictorial displays. Comparisons are made between these results and those for American subjects.     

Therapy for helpless monkeys

During the course of pilot studies and two formal experiments examining the learned-helplessness phenomenon in rhesus monkeys, 5 subjects failed to escape in a shuttlebox following earlier experience with aversive stimulation in primate-restraining chairs. The present report details a therapeutic manipulation designed to reverse these subjects' maladaptive behavior in the shuttlebox. Introduction of a different fear stimulus (a net previously used to restrain the animals) was found to be effective in inducing shuttlebox escape and avoidance learning. The implications of the present findings for an understanding of the learned-helplessness phenomenon and their relevance to therapy for human depression are discussed.     

Effects of list length and first-trial reward upon concurrent discrimination performance

Rhesus monkeys were given 2304 two-trial object discrimination problems that were presented as members of lists consisting of two, four, or eight problems. The problems within each list were presented concurrently, Trial 1 for all problems in the list being presented before initiation of Trial 2 for any problem. Each problem involved exposure of a single object on Trial 1, which was either rewarded or not rewarded, followed by presentation of the Trial 1 object along with a second object on Trial 2. Performance varied inversely with list length, and this effect became more prominent as a function of training. Performance after Trial 1 nonreward was substantially better than that after Trial 1 reward, and this effect became enhanced both with continued training and with increased list length. The findings were discussed in terms of Bessemer's short-term memory analysis of learning set.     

Spatial localization in children after changes in position

Five experiments investigated the young child's ability to retrieve a target after a change in the position of the child or the target. In Experiments I–IV 2- to 4-year-old children were rotated 90, 180, 270, or 360° about a stationary square table containing four identical hiding locations at each of the cardinal locations. The children tested performed this task significantly better than chance, but their errors reflected either their response biases in the absence of any information as to the location of the target, or the repetition of a response which had been successful in retrieving the target prior to the change in position. When the children were forced to respond rapidly, these errors increased significantly. In Experiment V a table top was rotated 90, 180, 270, or 360° in front of 3- to 10-year-old children. There were two cue situations. The child saw the rotation, or the child had to infer the rotation. Young children made errors of the types observed in Experiments I–IV. The ability to inhibit these errors increased with age. By 7 years of age performance was virtually perfect when the child could observe the change in position of the hidden object. The ability to infer the positional change developed more slowly and was good but not perfect at 10 years of age.     

Science,Values and Loves: Theologies as Expressive Constructions

Invited to write “a manifesto for [my] own theological position”, I begin with science and human rights as excellent examples of universalist aspirations of modernity. Modern individualism is important too, as particular existential loves shape each life. Science, morality, and personal loves are interwoven in theologies, as creative constructions. The sciences are important, as we need not only individual authenticity but also accountability. My position presented here is science-inspired naturalistic theism. It is not “religious naturalism”, given the categorical difference between facts and values. It is not “natural theology”, as inductive approaches do not reach that far. It comes closer to a “theology of nature”, but it does not assume the epistemic claims involved. I consider theologies to be important expressive constructions.     

Agents of Reform?: Children’s Literature and Philosophy

Children’s literature was first published in the eighteenth century at a time when the philosophical ideas of Jean-Jacques Rousseau on education and childhood were being discussed. Ironically, however, the first generation of children’s literature (by Maria Edgeworth et al) was incongruous with Rousseau’s ideas since the works were didactic, constraining and demanded passive acceptance from their readers. This instigated a deficit or reductionist model to represent childhood and children’s literature as simple and uncomplicated and led to children’s literature being overlooked and its contribution to philosophical discussions being undermined. Although Rousseau advocates freeing the child to develop, he does not feel that reading fiction promotes child development, which is a weakness in an otherwise strong argument for educational reform. Yet, rather ironically, the second generation of children’s writers, from Lewis Carroll onwards, more truly embraced Rousseau’s broader philosophical ideas on education and childhood than their predecessors, encouraging and freeing readers to imagine, reflect and actively engage in ontological enquiry. The emphasis had changed with the child being embraced in education and society as active participant rather than passive or disengaged recipient. Works deemed to be seminal to the canon of children’s literature such as Alice’s Adventures in Wonderland, Peter Pan and The Chronicles of Narnia challenge readers to work through conflicts many of which can be identified retrospectively as exhibiting postmodern characteristics. By exploring moral and spiritual dilemmas in their writing, Carroll, Barrie and Lewis’s works can be regarded as contributing to discussions on theodical postmodernism. The successes of The Lord of the Rings and Narnia films suggest that there is an interest in exploring moral dilemmas, fulfilling a need (perhaps for tolerance and understanding) in society at large. Children’s literature has an almost divine power to restore, to repair and to heal, all characteristics of theodical postmodernism but differing from the more widely held conception of postmodernism which pulls apart, exacerbates and exposes. Children’s literature therefore offers a healthy and constructive approach to working through moral dilemmas. In their deconstruction of childhood, these authors have brought children’s literature closer to aspects of enquiry traditionally found in the domain of adult mainstream literature. As the boundaries between childhood and adulthood become more fluid, less certain, debate is centring around whether the canon of children’s literature itself has become redundant or meaningless since there are no longer any restrictions on which subjects can be treated in children’s literature. Despite the fact that children’s literature clearly engages with difficult issues, it continues to be left out of the critical equation, not given serious attention, disregarded as simplistic and ignored in contemporary philosophical discussions concerning morality, postmodernism and the future of childhood. With children’s literature coming closer to mainstream literature, and exhibiting prominent features of postmodernism, however, it is only a matter of time before philosophical discussions actively engage with children’s literature and recognise its contribution to the resolution and reconciliation of ontological dilemmas. When this occurs, philosophy and children’s literature will re-engage, enriching contemporary investigations of existence, ethics and knowledge and fruitfully developing thought in these areas. This paper aims to contribute to this process.

On mediating equity,equality, and self-interest: The role of self-presentation in social exchange

Do individuals conform to various norms of reward allocation not necessarily in response to internal standards but rather, to win approval from relevant others? This study examined the role of self-presentation in mediating equity, equality, and self-interest within reward allocations. It was hypothesized that when others were aware of a subject's behavior, distributions would reflect that person's normative definition of the situation. Subjects allocated a $5.00 payment among themselves and three partners with unequal performance inputs. Informing the experimenter of one's decisions resulted in more equitable divisions, characterizing the employment-productivity relationship between experimenter and subject. When co-workers, defined as peers, were aware of allocations, an equality-based solution was favored. Allocators enhanced their own rewards beyond normative values only when their choices were completely private. Evidence was also found of postdecisional cognitive changes which maintained the belief that one acted justly in giving each partner what he deserved. These findings are consistent with the proposition that individuals maximize their own rewards, defined broadly to include social impression-formation and intrapsychic benefits. Apparently, self-presentational concerns mediate the relative salience of equity, equality, and self-interest in social exhange.     

The nature of equity-restoration: Some approval-seeking considerations

Subjects performed a proofreading task and evaluated its difficulty both beforehand and afterwards. They were overpaid or equitably paid by an experimenter who was or was not directly responsible for the level of pay they received, and who they believed would or would not see their post-test ratings. All subjects knew the experimenter would grade their task performance. Consistent with equity theory, overpaid subjects rated the task as having been more difficult than they had expected and did higher quality work than did equitably paid subjects. However, subjects who thought the experimenter would see their ratings (Aware condition) rated it as more difficult and performed more poorly on it than those who thought she would not see them (Unaware condition). Reported task difficulty increased among overpaid subjects under aware conditions, remained stable among overpaid subjects under unaware conditions, and decreased for equitably paid subjects. These findings suggested that what appears to be “equity-restoration” may be a self-presentation strategy designed to win the experimenter's approval, and that task ratings rather than performance will be used for this purpose when they can be communicated to the experimenter. The experimenter's responsibility for the subject's pay had no effect in the present study.     

The effects of a model's success or failure on subsequent aggressive behavior

It was of interest in the present study to examine the influence of both aggressive and nonaggressive models who are successful or nonsuccessful in reducing aggression from an aggressive opponent. Male and female subjects viewed a same-sexed model interact with an aggressive opponent in a reaction time task. Half the subjects observed an aggressive model while the remaining subjects observed a nonaggressive model. For half the subjects the model was successful in reducing the aggressiveness of the opponent. Results indicated that both the model's behavior and the consequences to the model (success/nonsuccess) were important determinants of subsequent aggression by the subject. Results are discussed in terms of current research and theory in aggression control.     

Reasonable Partiality to Domestic Animals

The paper deals with partiality flowing from special relationships. Two main problems are discussed. The first concerns the relationship between partiality and genuine moral obligations. If partiality can bring about such obligations only if it is reasonable, what requirements should it meet in order to be reasonable? The second problem is one of animal ethics. Can the concept of reasonable partiality help us articulate what is morally at stake in a current discussion about the treatment of domestic animals, viz. the European discussion about the castration of pigs?
