The gender-congruency effect in picture-word tasks

In Dutch noun phrases like “het boek” (the book) or “de kat” (the cat), the definite article (het or de) depends on the noun's grammatical gender (neuter or non-neuter). Schriefers reported that the production of a noun phrase like “het rode bed” (“the red bed”) in response to a colored picture takes less time when the picture is accompanied by a distractor word of congruent gender (e.g., “huis,” a het-word) than when it is accompanied by a word of incongruent gender (e.g., “hand,” a de-word). In three experiments we explored the characteristics of this gender-congruency effect. The following conclusions were reached. First, the gender-congruency effect is a rather robust phenomenon. Second, with the exception of a small effect in Exp. 2, no evidence was obtained for a gender-congruency effect when subjects were required to produce a single noun in response to a picture (e.g., “bed”). Third, the gender-congruency effect decreases with a decreasing familiarity of the distractor word. Implications for models of word production are discussed.

Alternative revision theories of truth

The Revision Theory of Truth (Gupta/Belnap 93) has been challenged in A. M. Yaqb's recent book The Liar Speaks the Truth. Yaqb suggests some non-trivial changes in the original theory — changing the limit rule — to avoid certain artifacts. In this paper it is shown that the proposed changes are not sufficient, i.e., Yaqb's system also produces artifacts. An alternative solution is proposed and the relation between it and Yaqb's solution is explored.     

A parallel rule activation and rule synthesis model for generalization in category learning

This paper proposes a distinction between primary generalization (transfer from stored exemplars to perceived targets) and secondary generalization (transfer from inferred abstractions to perceived targets). This distinction is embodied in the parallel rule activation and rule synthesis (PRAS) model, a production model capable of exemplar-based and abstraction-based categorization. As an exemplar model, the PRAS model is related to the generalized context model (Nosofsky, 1984). Exemplars are stored in memory encoded as condition-action rules. Working as an exemplar-based model, rules are activated on the basis of their strength and their similarity to the current to-be-categorized instance. Similarity between a target and a stored exemplar is weighted for attention to the dimensions of the psychological space. Depending on the value of a special parameter, the PRAS model is also able to operate as an abstraction model. In the latter case, it attempts to construct generalizing productions, which are activated according to the same rules as the exemplar-specific rules. The model is described in detail. It is applied to a number of important observations described in the research literature, and an experiment is reported that tested the usefulness of the proposed secondary-generalization mechanism. Finally, the discussion elaborates on the implications of the present study for further research.     

Movement errors and levels of processing in sentence production

From a corpus of 3,530 slips of the tongue in Spanish, a sample of 753 cases of movement errors was analyzed, comprising those tokens that could be unambiguously assigned to the major categories of anticipations, perseverations, exchanges, and shifts. The analysis was performed according to two main criteria: (a) the degree of correspondence between the linguistic elements interacting in an error, and (b) the distance between such elements in terms of the type and number of the intervening linguistic boundaries. The results of this analysis converge with those obtained in English, supporting a model of sentence planning with different levels of representation and processing. Furthermore, Spanish provides a clear case to attest the role of syllabic structure in production processes, the constraints set by word boundaries in sublexical errors, and the contribution of inflectional suffixes to the assignment of grammatical category to the root morphemes.     

First came the trees, then the forest: developmental changes during childhood in the processing of visual local-global patterns according to the meaningfulness of the stimuli

This study investigated how global and local perceptual processes evolve during childhood according to the meaningfulness of the stimuli. Children had to decide whether visually presented pairs of items were identical or not. Items consisted of global forms made up of local forms. Both global and local forms could represent either objects or nonobjects. In dissimilar pairs, items differed at one level (target level), while the other level included similar forms on both sides (irrelevant level). The results indicate an evolution from local preference at 4 years of age to adult-like global preference at 9 years of age. Moreover, as previously reported in adults, regardless of age, identification impaired performance when the irrelevant level was made of objects and the target level was made of nonobjects (interference). However, in younger children, this interference existed even when objects were present at all levels, suggesting that the strategy used to perform the comparison task also varied according to age.     

Application of stochastic modeling to the assessment of group and individual differences in cognitive functioning

This article begins with a guiding schema of relations among cognitive science, clinical science, and assessment technology. Emphasis is placed on stochastic modeling of cognitive processes. Basic models are adjusted so as to parsimoniously accommodate performance deviations occurring with psychopathology. Modified portions of models indicate functions affected by disorder, whereas portions remaining intact indicate spared functions. Findings from clinical cognitive science are applied to the individual case using Bayesian procedures. Methods are instantiated with respect to cognitive psychopathology of paranoid schizophrenia. The authors address observations and issues arising from this application, including integration of these methods with current assessment practices.     

Procesos de aprendizaje y terapia de conducta en la adicción a la heroína

Resumen

Múltiples principios de condicionamiento clásico y operante interaccionan en la adición a la heroína. Destacan la presencia de RC Compensatorias en forma de Síndrome de Abstinencia Condicionado (SAC) y distintos programas de reforzamiento en el estilo de vida, argot y efectos de la heroína. En evaluación conductual se estudian los correlatos subjetivos y psicofisiológicos del SAC; la validez externa de los autorregistros se logra mediante análisis de orina. En terapia de conducta los programas de amplio espectro se combinan con la intervención comunitaria y apoyo médico. A nivel metodológico se resalta la necesidad de usar múltiples criterios de medición, introducción del análisis multivariado y uso de diseños estadísticos, realización de seguimientos a largo plazo.     

Cognitive reappraisal in the context of oppression: implications for psychological functioning

Research on emotion regulation has shown cognitive reappraisal to be positively correlated with better psychological functioning. Prior research has failed to account for contextual influences on this important relationship. We examined how this relationship plays out across two United States ethnic groups that represent different contexts of oppression: Puerto Ricans, experiencing distal oppression (societal level) but not proximal oppression (immediate environment), and Latino Americans, experiencing both. We also captured individual beliefs regarding oppression of one's group and implications of that oppression by measuring oppressed minority ideology (OMI). Results confirmed our hypothesis that the relationship between reappraisal and psychological functioning would be moderated by the context of oppression (as measured by ethnic group membership and OMI). For Latino Americans high on OMI, reappraisal was negatively associated with psychological functioning. For Puerto Ricans, regardless of OMI, this relationship remained positive, suggesting a possible benefit for minorities in being surrounded by in-group members.
