The abstraction of visual prototypes by children

The present studies demonstrated that children as young as second graders could form prototypical representations from a set of highly similar stimuli. The prototype-plus-transformation model of this performance (Franks & Bransford, 1971) was contrasted with an attribute-frequency model (Neumann, 1974). Results supported the latter model when trigram stimuli were used to test differential predictions from the models.     

Clinical and pathophysiologic aspects of viral infections of the CNS

The available defensive mechanisms are generally sufficient to protect the central nervous system (CNS) against the penetration of infectious particles. The blood-brain-barrier plays a decisive role in this process. The present paper represents the most important circumstances realizing that: 1. The macrophage-lymphocyte-system, 2. the "oligoclonal-CSF-IgG-reaction", and 3. the influence of psychological and physiological burdens on clinical-chemical or immunological parameters. It seems to be important to overcome the instability of the immunosystem and to reestablish the base-line.     

Faculty work orientations as predictors of work attitudes in the physical and social sciences

This study examines the relationship between university professors' work orientation and attitudes toward their work. Specific and global work orientations are related to extrinsic and intrinsic attitudes toward (1) career attraction, (2) work satisfaction, and (3) commitment to the profession. The major findings of the study are (1) global work orientation is a strong predictor of attitudes toward intrinsic aspects of work in the social sciences and is a moderate predictor in the physical sciences; (2) specific work orientation is a strong predictor of attitudes toward extrinsic aspects of work in the physical sciences and is a moderate predictor in the social sciences; (3) global work orientation is not related to extrinsic work attitudes in the physical and social sciences; and (4) specific work orientation is not related to intrinsic work attitudes in the physical and social sciences.

The Need for and Possibility of a Christian Forgiveness Education in Schools

Individuals and communities occasionally need asking and giving forgiveness. Because the process of forgiving is not always well understood, it has become necessary to consider including forgiveness education in school pedagogy and in formal school programs such as Citizenship Education. This possibility is illustrated with examples from South Africa and The Netherlands. To date, forgiveness education has mostly taken the form of brief research interventions. It is recommended that forgiveness education, also from a Christian viewpoint, be given a more prominent place in school curriculums as well as in teacher education programs.     

Factor structure of the Hare Psychopathy Checklist: Youth Version (PCL: YV) in incarcerated adolescents

Two studies are reported on the underlying dimensions of the psychopathy construct in adolescents as measured by the Hare Psychopathy Checklist-Youth Version (PCL: YV; Forth, Kosson, & Hare, 2003). In Study 1, the PCL: YV item ratings for 505 male adolescents incarcerated in 5 different settings in North America were used to test the fit of 3 models that have been hypothesized to represent the structure of psychopathy in adults. A 4th model based on parceling PCL: YV items was also tested. In Study 2, these models were tested with a sample of 233 male adolescents incarcerated in 2 facilities in the United Kingdom. Model fit results indicated that the 18-item 4-factor model developed by Hare (2003) and a modified version of a 13-item 3-factor model developed by Cooke and Michie (2001) were associated with generally good fit. Because the 4-factor model is a less saturated model than the 3-factor model (better parameter to data point ratio), it survived a riskier test of disconfirmation. Implications for the nature of psychopathy in youth are discussed.
