Investigates conscious understanding during narrative comprehension as revealed through use of think-aloud methodology. Presents an analytical model of conscious understanding. Identifies three working memory operations in the protocols--operations which are functionally necessary to inferences in the protocols. Discusses data and current models…

Tests hypotheses from the model for contact-induced language change as formulated in Thomason and Kaufman (1998) and Thomason (1998). The model correctly predicts the asymmetries between the mutual influences of the Germanic and Romance varieties in Brussels, Belgium and Strasbourg, France, making it a very powerful tool for describing the…

Summarizes a keynote address that tested hypotheses from the model for contact-induced language change as formulated in Thomason and Kaufman (1998) and Thomason (1998). The model correctly predicts the asymmetries between the mutual influences of the Germanic and Romance varieties in Brussels, Belgium and Strasbourg, France, making it a very…

Seven peer commentaries are provided in response to a paper that tested hypotheses from a model for contact-induced language change as formulated in Thomason and Kaufman (1998) and Thomason (1998). The model correctly predicts asymmetries between mutual influences of Germanic and Romance varieties in Brussels, Belgium and Strasbourg, France,…

Responds to peer commentaries written in response to a paper examining the model for contact-induced language change as formulated in Thomason and Kaufman (1998) and Thomason (1998). The model correctly predicts asymmetries between mutual influences of Germanic and Romance varieties in Brussels, Belgium and Strasbourg, France, making it a very…

According to temporal distinctiveness models, items that are temporally isolated from their neighbors during list presentation are more distinct and thus should be recalled better. Event-based theories, by contrast, deny that time plays a role at encoding and predict no beneficial effect of temporal isolation, although they acknowledge that a…

The authors outline a cognitive and computational account of causal learning in children. They propose that children use specialized cognitive systems that allow them to recover an accurate "causal map" of the world: an abstract, coherent, learned representation of the causal relations among events. This kind of knowledge can be perspicuously…

This article offers a reformulation of the negative reinforcement model of drug addiction and proposes that the escape and avoidance of negative affect is the prepotent motive for addictive drug use. The authors posit that negative affect is the motivational core of the withdrawal syndrome and argue that, through repeated cycles of drug use and…

This article explicates the interaction between implicit and explicit processes in skill learning, in contrast to the tendency of researchers to study each type in isolation. It highlights various effects of the interaction on learning (including synergy effects). The authors argue for an integrated model of skill learning that takes into account…

Verb production is notoriously difficult for individuals with Broca's aphasia, both at the word and at the sentence level. An intriguing question is at which level in the speech production these problems arise. The aim of the present study is to identify the functional locus of the impairment that results in verb production deficits in Broca's…

Teleological explanations (TEs) account for the existence or properties of an entity in terms of a function: we have hearts because they pump blood, and telephones for communication. While many teleological explanations seem appropriate, others are clearly not warranted--for example, that rain exists for plants to grow. Five experiments explore…

This paper studies the dynamics of attempting to access two spatial memories simultaneously and its implications for the accuracy of recall. Experiment 1 demonstrates in a range of conditions that two cues pointing to different experiences of the same object location produce little or no higher recall than that observed with a single cue.…

This paper comments on the article by Plaut and Booth. Plaut and Booth's first simulation shows that there is essentially perfect discrimination between word and nonwords sharing the same orthographic structure when the simulation is carried out in the way we suggested. We take the view that Plaut and Booth's new simulation work settles little…

Observers made speeded old-new recognition judgments of color stimuli embedded in a multidimensional similarity space. The paradigm used multiple lists but with the underlying similarity structures repeated across lists, to allow for quantitative modeling of the data at the individual-participant and individual-item levels. Correct rejection…

The authors used a modified Simon task (J. R. Simon, 1969) to assess the automatic recognition of handedness. Participants responded to the color of a circle in the center of the photograph of a right or a left hand, displayed in the center of the computer screen. A regular Simon effect was found for back views, whereas a reverse Simon effect was…
