Trials per problem and age as factors in learning set formation of children

Discrimination learning set performance was examined in preschool children as a function of age and number of trials per problem. Subjects 3, 4, 5, and 6 years old were trained over three 72-trial sessions. Half of the children at each age were given problems three trials in length, and half received 12-trial problems. As predicted, younger children (3 and 4-year-olds) performed significantly better for 12 than for three trials per problem, whereas no differences in performance were evident for older children. Response pattern analyses revealed that younger children, especially those receiving less exposure within problems, produced a higher proportion of stimulus alternation and position determined response sequences than did older children. These results contradict the commonly held assumption that learning set acquisition is simply a function of the total number of trials presented and indicate that the amount of exposure to individual problems is a factor in problem solution for young human subjects.     

Peer and parent-child interaction before and after enrollment in nursery school

Forty-five three-year-olds and their parents participated in the research. Twenty-four of the children were observed two months and one week before, as well as two months after, enrollment in a nursery school. The others were observed at comparable intervals, but remained at home in the fulltime care of their parents. On all occasions, the children who were about to enter or had entered nursery school engaged in more positive interaction with and sought more proximity to their parents than the home care children did. These tendencies were unaffected by enrollment in nursery school. There were no differences between nursery school and home care children on measures of peer interaction eithe before or after nursery school began. The need to consider differences between nursery school and home care children that antedate enrollment is emphasized.     

Infants' search for visible objects: implications for the interpretation of early search errors

This study examined the error patterns of 9-month-old infants searching for hidden objects and objects that were visible within a container. Although errors occurred in both conditions, there were important differences between them. When the object was hidden, infants showed significant perseveration in that they searched more often at the object's previous hiding place than at a control location. When the object was visible, however, they made fewer errors and the errors they did make were as likely to be to the control location as to the previous hiding place. These results suggest that infants' errors in searching for a visible object reflect lapses of attention rather than systematic misunderstandings of objects or space and so are not incompatible with an information-processing account of early search.     

Deconstruction and creation: an Augustinian deconstruction of Derrida

In recent continental philosophy of religion there has been significant attention paid to the Abrahamic doctrines of creation ex nihilo and divine omnipotence, especially by deconstructive thinkers such as Derrida, Caputo, and Keller. For these thinkers, the doctrine represents a form of agency that does violence to various forms of alterity. While broadly supportive of their fundamental philosophical and ethico-political views, especially about the primordiality of alterity, I differ from them in that I argue that creation ex nihilo articulates the very structure of the alterity they are concerned with. The essay proceeds through a reading of Derrida’s representation of the doctrine and a “deconstruction” of his view by means of a reading of Augustine and Anselm.     

An evaluation of the effects of supplemental “fluency” training during maintenance

The voice onset time (VOT) of two groups of treated stutterers and a normal-speaking group was assessed by spectrographic analysis. Both groups of stutterers had significantly slower VOT than the normal speakers. The experimental group of stutterers was given 8 wk of “fluency” training designed to remediate characteristics of speech identified as related to “tenuous” fluency. The control group of stutterers received ongoing maintenance therapy. Posttreatment VOT was assessed. The experimental stuttering group had significantly decreased their VOT in the direction of the normal-speaking group, whereas the control group of stutterers had a greater VOT between pre- and posttreatment. The implication of these results for the maintenance of fluency are discussed.     

Cortical localization of finger spelling and oral language: A case study

Finger spelling of letters and words was mapped by means of the cortical stimulation procedure in a hearing patient undergoing a left dominant anterior temporal lobe resection for relief of a seizure disorder. Finger spelling was disrupted at five sites: three overlapping with one or more oral language functions at sites in the classical posterior language area, two relating only to finger spelling in the anterior temporal region. Following the resection which included these latter sites, both short- and long-term postoperative deficits in finger spelling are described. Implications for the organization of manually based communication behavior in the left hemisphere are discussed.     

APORETIC POSSIBILITIES IN CATHERINE KELLER'S CLOUD OF THE IMPOSSIBLE

In stressing the beauty of ignorance, of not knowing in the usual manner, Catherine Keller's Cloud of the Impossible evokes the death of a metaphysical (A)uthorial presence and the dissolution of closed systems of meaning. In this article, I view her text as part of a crisis of modernity that challenges dominant theological pathways, on which certain problematic views of the human have been constructed. In my reading, Keller's Cloud enriches humanistic thinking in the West and I explore the themes it shares with my own work in religious naturalism: there is no escape from the radical relationality and the irreducible materiality that structure human existence. I also emphasize that textual strategies are mere seductive, disembodied abstractions without acknowledging the force of materiality. Materiality matters; and I explore ways in which religious naturalism demonstrates how it does. In light of Keller's rich analysis, I focus on a “learned ignorance” that accompanies all of our limited interpretations emerging from the shifting, precarious positionalities as we rethink our relationality to each other and to all that it is.     

HOW RADICALLY CAN GOD BE RECONCEIVED BEFORE CEASING TO BE GOD? THE FOUR FACES OF PANENTHEISM

Panentheism has often been put forward as a means for bringing theology and science into dialogue, perhaps even resolving some of the major tensions between them. A variety of “faces” of panentheism are distinguished, including conservative, metaphysical, apophatic, and naturalist panentheisms. This series of increasingly radical panentheisms is explored, each one bringing its own core commitments, and each describing very different relationships between religion and science. We consider, for example, the diverse ways that the radical panentheisms construe emergent phenomena in the natural world. In the end, comparing the increasingly radical forms of panentheism yields a new understanding of the state of the religion/science dialogue today.     

THE FAULT IN US: ETHICS,INFINITY, AND CELESTIAL BODIES

Catherine Keller's Cloud of the Impossible knits together process theology and relational ontology with quantum mechanics. In quantum physics, she finds a new resource for undoing the architecture of classical metaphysics and its location of autonomous human subjects as the primary gears of ethical agency. Keller swarms theology with the quantum perspective, focusing in particular on the phenomenon of quantum entanglement, by which quantum particles are found to remain influential over each other long after they have been physically separated—what Albert Einstein and his collaborators recklessly dismissed as “spooky action at a distance.” This spooky action, Keller suggests, reroutes process thought—classically concerned with flux—to a new concern with intransigence—particularly the intransigence of the ethical relationship. Attending to the ethical urgency of the Other, she leaves process theology in a position of susceptibility to the moral imperative posed by the marginalized, the victimized, and the oppressed. This essay argues that although the ontological work of Keller's book productively integrates quantum physics into process theology, the ethical dimension of relationality is left cold in the quantum field. This is because, contra the ethical framework of contemporary deconstruction, which, following Emmanuel Levinas, sees ethical relationships as emerging out of a dynamic of infinite distance, moral connection has nothing to do with the remote reaches of the quantum scale or the macro‐scale limits of space—nothing to do with “infinity” at all. Ethics emerges out of a much messier landscape—the evolved dynamic of fleshy, finite, material bodies. Rather than seeing ethical labor as a matter of physics, my contention (and here I think I am arguing with, rather than against Keller) is that interdisciplinary undertakings like Cloud of the Impossible are ethical disciplinary practices, re‐acquainting us with the non‐sovereignty of the self in order to open up new habits of relating rather than spotlighting ethical imperatives.     

Interference effects on preschool children's learning sets

Four experiments investigated interference in 5-year-olds' learning sets. Experiment 1 manipulated intertrial and interproblem intervals, showing that increased intertrial intervals retarded performance. Long interproblem intervals interacted with short intertrial intervals to produce performance facilitation. Experiment 2 investigated interpolations within problems with either similar or dissimilar stimulus presentations. Similar stimuli caused greater performance decrements than dissimilar. Experiment 3 hypothesized that the within-subjects design of Experiment 1 masked interproblem interval effects. Testing between-subjects established that increased interproblem delays facilitate performance. In Experiment 4 interproblem delays were further tested in a series of shifts within and between dimensions. Increased delays more greatly benefited shifts within dimensions. It is concluded that intertrial and interproblem intervals affect learning set performance differentially. Intertrial delays result in performance deterioration due in part to interference. Interproblem delays facilitate performance at least in part by providing the opportunity for suppression of proactive interference, and perhaps in part by providing the opportunity for constructive cognitive processing.
