First Annual Diversity Challenge: “How to Survive Teaching Courses on Race and Culture”

The authors discuss the highlights of the 1st annual Diversity Challenge held October 11–12, 2001, at Boston College, Boston, MA. The Challenge's general focus was preparing educators to cope with the resistances encountered when they teach about race and ethnic culture. This introduction (a) provides an overview of the proceedings, (b) summarizes themes of presentations and articles selected, and (c) offers recommendations for subsequent events. Los autores analizan el primer Reto de Diversidad, que tuvo lugar del 11 al 12 de octubre, 2001, en Boston College, Boston, Massachusetts. El próposito del reto fue preparar a los profesores para que puedan enfrentar las dificultades que resultan de enseñar los temas de la raza y la cultura étnica. Esta introducción (a) da un breve resumen de los procedimientos, (b) resume los temas de las presentaciones y los ensayos seleccionados, y, (c) sugiere recommendaciones para eventos posteriores.     

Modern Molar Behaviorism And Theoretical Behaviorism: Religion And Science.

Baum and staddon disagree on the status of internal states in behavior analysis. Baum advocates molar behaviorism, treating behavior in temporally extended segments and so avoiding the need for internal states. Staddon argues that internal states merely represent the effects of different histories and that their use brings behavior analysis in line with the established sciences. The dispute is one form of the age‐old molar—molecular controversy that characterized Aristotle's disagreement with Plato. Both molar and molecular analyses have their place, but molar behaviorism may apply more naturally to a variety of phenomena, ranging from the matching law and avoidance learning to socalled “higher mental processes.” When molecular analysis involves internal states, as in Staddon's Theoretical Behaviorism (or New Behaviorism), misunderstanding will be inevitable and behaviorism will be seen as one more instance of the mediational theories in which psychology has long been mired. Such theories have long dominated the physical sciences, where their usefulness is indisputable, but psychology is far behind the physical sciences and nonmediational molar behaviorism better suits a discipline that lacks the methods and the data of the established sciences.     

Toward a theory of intrinsically motivating instruction

First, a number of previous theories of intrinsic motivation are reviewed. Then, several studies of highly motivating computer games are described. These studies focus on what makes the games fun, not on what makes them educational. Finally, with this background, a rudimentary theory of intrinsically motivating instruction is developed, based on three categories: challenge, fantasy, and curiosity. Challenge is hypothesized to depend on goals with uncertain outcomes. Several ways of making outcomes uncertain are discussed, including variable difficulty level, multiple level goals, hidden information, and randomness. Fantasy is claimed to have both cognitive and emotional advantages in designing instructional environments. A distinction is made between extrinsic fantasies that depend only weakly on the skill used in a game, and intrinsic fantasies that are intimately related to the use of the skill. Curiosity is separated into sensory and cognitive components, and it is suggested that cognitive curiosity can be aroused by making learners believe their knowledge structures are incomplete, inconsistent, or unparsimonious.     

Cross-cultural effects of parent warmth and control on aggression and rule-breaking from ages 8 to 13

We investigated whether bidirectional associations between parental warmth and behavioral control and child aggression and rule-breaking behavior emerged in 12 cultural groups. Study participants included 1,298 children (M = 8.29 years, standard deviation [SD] = 0.66, 51% girls) from Shanghai, China (n = 121); Medellín, Colombia (n = 108); Naples (n = 100) and Rome (n = 103), Italy; Zarqa, Jordan (n = 114); Kisumu, Kenya (n = 100); Manila, Philippines (n = 120); Trollhättan/Vänersborg, Sweden (n = 101); Chiang Mai, Thailand (n = 120); and Durham, NC, United States (n = 111 White, n = 103 Black, n = 97 Latino) followed over 5 years (i.e., ages 8–13). Warmth and control were measured using the Parental Acceptance-Rejection/Control Questionnaire, child aggression and rule-breaking were measured using the Achenbach System of Empirically-Based Assessment. Multiple-group structural equation modeling was conducted. Associations between parent warmth and subsequent rule-breaking behavior were found to be more common across ontogeny and demonstrate greater variability across different cultures than associations between warmth and subsequent aggressive behavior. In contrast, the evocative effects of child aggressive behavior on subsequent parent warmth and behavioral control were more common, especially before age 10, than those of rule-breaking behavior. Considering the type of externalizing behavior, developmental time point, and cultural context is essential to understanding how parenting and child behavior reciprocally affect one another.     

Implicit word activation during prerecognition processing: False recognition and remember/know judgments

Recognition memory for spoken words is influenced by phonetic resemblance between test words and items presented during study. Presentation of derived nonwords (e.g., /d/ransparent or transparen/d/) on a study list produces a higher than normal false recognition rate to base words (e.g., transparent). Test words that share beginning phonemes with studied nonwords have more false recognitions than do those that share ending phonemes. The latter difference has been attributed to familiarity resulting from prerecognition processing of spoken stimuli. As a listener hears/traens/, "transparent" may be activated as a potential solution. In the present experiments, we minimized contributions of postrecognition processing to this phenomenon by presenting a semantically unrelated test word (transportation) that was also expected to be activated during prerecognition stages of processing. The results indicated that false recognition was increased for words presumed to be activated only during prerecognition processing. Remember (R) and know (K) judgments revealed that the majority of studied words were R, and the majority of false recognitions were K. The lowest proportion of R judgments occurred for test words that were not activated during postrecognition processing (e.g., transportation and control words).     

The effects of methylphenidate on levels of processing and laterality in children with attention deficit disorder

Effects of stimulant medication (methylphenidate) on levels (feature, name, semantic) of word processing by the left and right hemisphere were assessed in 31 attention- deficit- disordered children. In a double-blind procedure, same- different decisions were made to tachistoscopically presented word pairs under medication and placebo. Analysis of manual response times failed to show any negative effects of medication. Feature decisions were faster than name decisions, which were faster than semantic decisions. Methylphenidate induced a right visual field advantage (left hemisphere) for the name decision, which was interpreted as a normalization effect. The results suggest that (1) methylphenidate may selectively improve the phonological level of word processing and (2) methylphenidate's favorable therapeutic effect is produced through inhibition of excessive right hemisphere activity in response to task demands that engage the left hemisphere.This research is based in part upon a doctoral thesis completed by the first author in the Department of Education, University of Toronto.
