Category number effects on rule-based and information-integration category learning were investigated. Category number affected accuracy and the distribution of best-fitting models in the rule-based task but had no effect on accuracy and little effect on the distribution of best-fining models in the information-integration task. In the 2 category…

The Artificial Grammar Learning task has been used extensively to assess individuals' implicit learning capabilities. Previous work suggests that participants implicitly acquire rule-based knowledge as well as exemplar-specific knowledge in this task. This study investigated whether exemplar-specific knowledge acquired in this task is based on the…

Four experiments are presented that competitively test rule- and exemplar-based models of human categorization behavior. Participants classified stimuli that varied on a unidimensional axis into 2 categories. The stimuli did not consistently belong to a category; instead, they were probabilistically assigned. By manipulating these assignment…

The authors present a similarity-based model of induction and categorization in young children (SINC). The model suggests that (a) linguistic labels contribute to the perceived similarity of compared entities and (b) categorization and induction are a function of similarity computed over perceptual information and linguistic labels. The model also…

SUSTAIN (Supervised and Unsupervised STratified Adaptive Incremental Network) is a model of how humans learn categories from examples. SUSTAIN initially assumes a simple category structure. If simple solutions prove inadequate and SUSTAIN is confronted with a surprising event (e.g., it is told that a bat is a mammal instead of a bird), SUSTAIN…

Varying levels and types of husband violence may be conceptualized as typologies of maritally violent men. Across studies, batterer subtypes resembling those proposed by Holtzworth-Munroe and Stuart (1994) have been identified and generally found to differ in predicted ways. Longitudinal data from this study suggests that the subgroups continued…

The development of empirically based behavioral and psychological typologies provides clear evidence that offenders vary across types. A review and synthesis of the literature reveals three types of batterers common across current typology research - a low, moderate, and high-risk offender. Examination of these types demonstrates that most male…

Although it is now well established that object concepts are situated within broader systems of theoretical knowledge, it is less clear how theories influence the use of object concepts at various points throughout the continuum of expertise. Two studies were conducted to investigate the impact of specific theories (concerning dinosaurs) and…

College women who did (n=33) and did not (n=56) label their sexual assault experience as rape provided written descriptions of their sexual assaults. From these descriptions we identified eight different sexual assault situations. Women who labeled their experience as rape were most likely to have been assaulted forcefully by an acquaintance,…

In their original report [Kunde, W., Kiesel, A., & Hoffmann, J. (2003). Conscious control over the content of unconscious cognition. "Cognition," 88, 223-242] maintain that ''unconscious stimuli [do not] owe their impact [...] to automatic semantic categorization'' (p.223), and instead propose the action-trigger theory of unconscious priming. In a…

The dimensional change card-sorting task (DCCS task) is frequently used to assess young children's executive abilities. However, the source of children's difficulty with this task is still under debate. In the standard DCCS task, children have to sort, for example, test cards with a red cherry or a blue banana into two boxes marked with target…

The type of information (taxonomic or thematic) available at different levels of knowledge was investigated. Following extensive norming to identify taxonomic and thematic associates of low-frequency nouns, participants determined if taxonomic or thematic associates were meaningfully related to target words at three levels of knowledge: target…

The taxometric method is an increasingly popular statistical approach that tests whether the structure of a latent construct is categorical or continuous. This article presents the key conceptual and methodological issues that should be addressed in an informative taxometric investigation. We aim to help potential users of taxometrics determine:…

The present study undertook an updated citation analysis of Skinner's (1957) "Verbal Behavior". All articles that cited "Verbal Behavior" between 1984 and 2004 were recorded and content analyzed into one of five categories; four empirical and one nonempirical. Of the empirical categories, studies that employed a verbal operant from Skinner's…

This paper measures the technical efficiency of 16 selected colleges and universities in Metro Manila, Philippines, using academic data for the SY 2001-2005. Using the data envelopment analysis (DEA), on average, schools posted 0.807 index score and need additional 19.3% efficiency growth to be efficient. Overall, there are top four efficient…
