UZNADZE'S SET AND SECOND LANGUAGE LEARNING

L'A. classe en “ bons ” (N = 40) et en “ mauvais ” (N = 40), des élèves qui étudient le français (seconde langue) en comparant le total des notes normalisées obtenues à des tests de compréhension du français écrit et oral aux notes normalisées obtenues à un test d'aptitude scolaire (SCAT). Il pose en hypothèse que si L'on fait des mesures de fixation et d'extinction d'un “ set ” en matière de sensibilité bilité tactile, on trouvera des différences entre les “ bons ” et les “ mauvais ”. Reprenant la méthode d'Uznadze, il constate qu'entre les deux types d'élèves, il n'y a pas de différence significative (p > .05) dans le nombre d'essais nécessaires à la fixation d'un “ set ”, mais que, par contre, il y a une différence significative dans le nombre d'essais nécessaires à L'extinction du “ set ” : pour les élèves qui sont bons dans L'apprentissage d'une seconde langue, le nombre d'essais nécessaires à L'extinction est plus faible.     

CHARACTERISTICS OF SUCCESSFUL AND DROPOUT MDTA TRAINEES1

A study was designed to compare several variables of Manpower Development Training Act (MDTA) clients who dropped out of the program with those of clients who completed the program. A random sample of application cards was drawn for individuals enrolled in MDTA adult classes in Milwaukee, Wisconsin. Trainees who completed the program were more likely to be married, older, characterized by a more stable employment history prior to entering the program, and slightly more educated than were program dropouts. Clients who completed the program versus those who did not were not significantly different on the following variables: (1) sex; (2) counseling versus no counseling; (3) race; and (4) client reported physical disability.     

The aggression-coercion cycle: Use of seclusion and restraint in a child psychiatric hospital

The widespread use of seclusion and restraint in child psychiatric hospitals to manage aggression and noncompliance is based on the assumption that coercive consequences reduce the frequency of undesirable behaviors exhibited by the patients. We report a study of the use of seclusion and restraint in a public child psychiatric hospital during a 3-year period. Twenty-eight percent of the patients had been secluded or restrained a total of 1670 times. About 25% of these patients had been secluded more than five times during their hospitalization, and 32% had been placed in restraints more than once. Behaviors that typically resulted in repeated seclusion included physical aggression toward staff, verbal aggression toward peers, non-compliant or oppositional behavior, and self-harm. Variables that predicted patients most at risk for repeated seclusion included age, gender, and psychiatric diagnosis. The predictor variables for those most at risk for repeated restraint included age, property destruction, and self-harm. The high rates of use of seclusion and restraint suggest that these methods for controlling the behavior of children and adolescents in this child psychiatric hospital may not have been therapeutic. We suggest that staff in such hospitals engage in a pattern of behavior characterized by an aggression-coercion cycle, in which increasingly aggressive and coercive behaviors are exhibited by both patients and staff.     

A logic of intentions and beliefs

Intentions are an important concept in Artificial Intelligence and Cognitive Science. We present a formal theory of intentions and beliefs based on Discourse Representation Theory that captures many of their important logical properties. Unlike possible worlds approaches, this theory does not assume that agents are perfect reasoners, and gives a realistic view of their internal architecture; unlike most representational approaches, it has anobjective semantics, and does not rely on anad hoc labeling of the internal states of agents. We describe a minimal logic for intentions and beliefs that is sound and complete relative to our semantics. We discuss several additional axioms, and the constraints on the models that validate them.     

Grading the ‘cultural literacy’ project

The essay examines the argument advanced by E.D. Hirsch, Jr., for instituting ‘cultural literacy’ as a fundamental priority of schools. A number of confusions and equivocations in Hirsch's reasoning are identified, and the propensity of his project to indoctrinate is exposed. Among the features of Hirsch's argument shown to be troubling are his shifting construal of ‘language’, his inconsistency about the requirements of cultural literacy, and his uncritical relation to traditional images of the American past and present. The upshot is to raise the question why Hirsch's project has elicited wide support and praise.     

The early development of empathy: Self-regulation and individual differences in the first year

A longitudinal study of 45 mothers and their first-born infants was conducted to identify developmentally meaningful, individual differences in children's primitive empathic responding at 12 months of age, and to determine whether differences in self-regulatory skills assessed at 4 months might underlie any differences in empathic responding observed. Personal distress responses analogous to those observed in older children and adults were identified in one-third of the sample at 12 months of age. These distress responses were associated with indices of poorer self-regulatory skills in social contexts at 4 months of age. The results are interpreted within the broader framework of the development of self-regulatory strategies in the early childhood years.This research was supported by grants from the Australian Research Council, the National Research Fellowship Scheme, and the Macquarie University Research Grant Scheme.

Individual Differences in the Pursuit of Self-Uniqueness Through Consumption

In this paper, we report an original study of the relationships between self-attributed need for uniqueness and several consumer dispositions. The results indicate that the self-attributed need for uniqueness is related to consumers' desires for scarce, innovative, and customized products and to consumers' preferences for unusual shopping venues, but not to consumers' susceptibilities to normative influence. Moreover, we find that these relationships are mediated by a latent variable reflecting individual differences in the tendency to pursue uniqueness through consumption. The theoretical and practical implications of these results are discussed along with directions for future research.     

THE CREDIBLE SHRINKING ROOM:

Abstract— Becoming a proficient symbol user is a universal developmental last in the first years of life, but delecting and mentally representing symbolic relations can be quite challenging for young children To test the extent to which symbolic reasoning per se is problematic, we compared the performance of 2-year-olds in symbolic and nonsymbolic versions of a search task. The children had to use their knowledge of the location of a toy hidden in a room to draw an inference about where to find a miniature toy in a scale model of the room (and vice versa) Children in the nonsymbolic condition believed a shrinking machine had caused the room to become the model They were much more successful than children in the symbolic condition, for whom the model served as a symbol of the room The symbol understanding and use.
