Object processing in visual perception and action in children and adults

We investigated whether 6- and 7-year-olds and 9- and 10-year-olds, as well as adults, process object dimensions independent of or in interaction with one another in a perception and action task by adapting Ganel and Goodale's method for testing adults (Nature, 2003, Vol. 426, pp. 664-667). In addition, we aimed to confirm Ganel and Goodale's results in adults to reliably compare their processing strategies with those of children. Specifically, we tested the abilities of children and adults to perceptually classify (perception task) or grasp (action task) the width of a rectangular object while ignoring its length. We found that adults process object dimensions in interaction with one another in visual perception but independent of each other in action, thereby replicating Ganel and Goodale's results. Children processed object dimensions interactively in visual perception, and there was also some evidence for interactive processing in action. Possible reasons for these differences in object processing between children and adults are discussed.

Size and Structure of the Holistic Milieu: A Comparison of Local Mapping Studies in Austria and Sweden

This article presents the results of two local mapping studies in Sweden and Austria that follow the methodological procedure of the British Kendal project. All practitioners offering courses, therapies or counseling in the areas of holistic spirituality and complementary health methods (such as yoga, Reiki, kinesiology, astrology, and shamanism) were mapped. A sub-sample of the mapped practitioners were contacted in person and asked about their professional situation and the number of their clients. On the basis of these data, the proportion of persons participating in the holistic milieu was estimated. The article discusses the similarities and differences between the two regions in regard to the supply of specific types of holistic activities, the professional situation of the practitioners, and the proportion of the population involved in holistic activities. The level of engagement in holistic activities in the Swedish, Austrian, and British mapping areas is also compared with the level of church attendance in the three countries.     

The perceptual origins of the abstract same/different concept in human infants

Very few experiments have studied the two item same/different relation in young human infants. This contrasts with an extensive animal literature. We tested young infants with two novel tasks designed specifically to provide convergent comparative measures. Each infant completed both tasks allowing an assessment of their understanding of the abstract concept rather than task-specific abilities. In a looking time task with photographic stimuli, we found that 8-month-olds are sensitive to the relation but 4-month-olds are not. The second task used an anticipatory eye movement paradigm with simple geometric stimuli. On each trial, two colored shapes appear and moved upwards behind an occluder. They reappeared on either the upper left or right depending on the relation between them. Infants at both ages learned and generalized the dependency but only for the different relation. These results show that human infants can learn the same/different concept but that, in strong continuity with animal results, their abilities are firmly grounded in perception.     

Evidence of Common Timing Processes in the Control of Manual,Orofacial, and Speech Movements

Recent investigations of timing in motor control have been interpreted as support for the concept of brain modularity. According to this concept, the brain is organized into functional modules that contain mechanisms responsible for general processes. Keele and colleagues (Keele & Hawkins, 1982; Keele & Ivry, 1987; Keele, Ivry, & Pokorny, 1987; Keele, Pokorny, Corcos, & Ivry, 1985) demonstrated that the within-subject variability in cycle duration of repetitive movements is correlated across finger, forearm, and foot movements, providing evidence in support of a general timing module. The present study examines the notion of timing modularity of speech and nonspeech movements of the oral motor system as well as the manual motor system. Subjects produced repetitive movements with the finger, forearm, and jaw. In addition, a fourth task involved the repetition of a syllable. All tasks were to be produced with a 400-ms cycle duration; target duration was established with a pacing tone, which then was removed. For each task, the within-subject variability of the cycle duration was computed for the unpaced movements over 20 trials. Significant correlations were found between each pair of effectors and tasks. The present results provide evidence that common timing processes are involved not only in movements of the limbs, but also in speech and nonspeech movements of oral structures.     

Confucianism,Perfectionism, and Liberal Society

Confucian scholars should satisfy two conditions insofar as they think their theories enable Confucianism to make contributions to liberal politics and social policy. The liberal accommodation condition stipulates that the theory in question should accommodate as many reasonable conceptions of the good and religious doctrines as possible while the intelligibility condition stipulates that the theory must have a recognizable Confucian character. By and large, Joseph Chan’s Confucian perfectionism is able to satisfy the above two conditions. However, contrary to Chan and many other Confucian scholars, I argue that any active promotion of Confucianism will violate the liberal accommodation condition. I propose the “wide view of moderate perfectionism,” which enables Confucianism to shed light on a wide range of political and social issues without promoting Confucianism actively. Thus, I present a new approach to the long-standing question of how Confucianism may improve political and social development in a liberal society.     

Personal construct theory and the argument against mental illness

An attempt is made to integrate Thomas Szasz's 0974) theory of personal conduct and George Kelly's (1955) theory of personal constructs (PCT). It is argued that PCT provides an alternative to the void left behind by Szasz's negation of mental illness. Because PCT is concerned with psychological, rather than physiological, constructions of problems in living, it is not compatible with the biological model associated with Diagnostic and Statistical Manual of Mental Disorders (DSM) diagnostic categories. Rather, it is in keeping with the views of Szasz. Kelly's and Szasz's writings are used to support this view. Kelly's transitive diagnosis approach to “mental illness”, wherein diagnosis and therapy are construed as process oriented as opposed to category driven, is described as an alternative to the biological model. A contextualist approach (Sarbin & Mancuso, 1980) is also discussed. These approaches not only empower clients and allow them to assert responsibility and control over their lives, but also provide an alternative system to the one rejected by Szasz.
