Intrinsic Value as a Reason for the Preservation of Minority Cultures

In the Netherlands, the policy of supporting the efforts of ethnic-cultural minorities to express and preserve their cultural distinctiveness, is nowadays considered as problematic because it might interfere with their integration into the wider society. The primary aim is now to reduce these groups' unemployment rate and to stimulate their participation in the wider society. In this article I consider how the notion of the intrinsic value of cultures, if sensible, might affect the policy regarding ethnic-cultural minorities. I develop a theory of intrinsic value of culture, as an analogy of the theory of intrinsic value of non-human natural entities. My conclusion is that the dominant cultural group in the Netherlands should preserve clearly deviant minority cultures which have considerable intrinsic value.     

Event-related potential studies of cerebral specialization during reading: I. Studies of normal adults

A number of methodological features were incorporated in a paradigm designed to maximize the likelihood of finding reliable event-related potential (ERP) signs of functional specializations between and within the cerebral hemispheres. Every subject was more accurate in identifying words presented to the right than to the left visual field. The morphology of the ERPs elicited by these words varied considerably as a function of electrode position both within and between the hemispheres. Amplitude asymmetries of ERP components recorded from occipital regions of the two hemispheres varied systematically with the position of the word in the visual field. On the other hand, ERPs from more anterior (temporal and frontal) regions displayed large asymmetries which were in the same direction regardless of the visual field of word presentation. The most prominent such asymmetry was in the negativity in the region 300–500 msec (N410) which was larger in the left than the right hemisphere in every subject. These results demonstrate that in this paradigm which demands specialized language processing ERPs are sensitive to aspects of cerebral organization both within and between the two hemispheres.     

Distortions in judged spatial relations

In three experiments, we explore distortions in subjects' judgments of relative geographical relations. People make large systematic errors in judging the geographical relations between two locations that are in different geographical or political units. There is a strong tendency to distort the judged relation to conform with the relation of the superordinate political unit. To account for this result, we present a model in which spatial information is stored hierarchically. Spatial relations between any two locations are stored explicitly only if those locations are within the same superordinate unit. Spatial relations not stored are inferred by combining the relations from between and within superordinate units.     

A computer system for automatically constructing stimulus material

A FORTRAN system for constructing various kinds of stimulus materials is described. A user enters the basic components of an experiment (stimulus items, presentation parameters, trial identifiers, etc.) as files, and uses the system to combine the basic files, automatically constructing the desired stimuli. The system contains file-manipulation functions for combining files (including factorial combination), functions for separating out parts of a file, and functions for randomizing files. The user can use the standard FORTRAN function-embedding and function-definition features to easily specify elaborate operations on the basic files to construct complex stimulus files.     

Teacher awareness of classroom dyadic interactions

Systematic classroom observation has frequently been used to provide teachers with feedback as to the type and frequency of their interactions with students. This process assumes that teachers are unaware of their interaction patterns; however, this assumption has seldom been tested directly. In order to test this hypothesis, the interactions between teachers and individual students in 30 classrooms were observed. Immediately following these observations teachers were asked to estimate the frequency of occurrence of various types of interactions. The results indicated a general lack of awareness of the frequency of occurrence of the types of interactions observed.     

Autonomic learning

Academic achievement was resolved into its intellectual and motivational components. IQ, personality variables, and parameters of operant and classical conditioning of autonomic nervous system controlled variables were examined in 99 black inner-city high school seniors. Six physiological variables(respiration, heart rate, finger plethysmogram, frontalis muscle potential, palmar skin conductance, and palmar skin potential) were analyzed by computer using analog-to-digital conversion and a Points of Interest (PI) program. Psychological measures were full WAIS IQ, Edwards Personality Inventory(EPI), Cattell Sixteen Personality Factor Questionnaire(16PF), McClelland need Achievement test(n Ach), Object Sorting test, Minnesota Counseling Inventory(MCI), Level of Aspiration Board, and Rotter—Miller Locus of Control. Achievement(Ach) was defined as the residuals of total grade point average(GPA) regressed on IQ. Each of 19 variables which discriminated significantly between high and low achievers was employed in step-wise regression analyses for GPA and Ach separately. In a regression analysis of variance of GPA, IQ=20.44%, EPI=9.08%, and physiological measures =21.37%(operant conditioning =18.70%; classical conditioning =2.67%). Combined measures of motivation(psychological and physiological) =30.45% of the variance in GPA. The entire psychological and physiological test battery, including IQ, contributed a total of 50.89% of the variance in GPA. In a regression analysis of variance in achievement, psychological measures, other than IQ(six EPI and one 16PF), =11.0% and physiological measures =30.3%. As a replication, this study demonstrated significant correlation between autonomic conditioning and school achievement.
