Cognitive psychology lacks explicit theories that encompass more than a single experimental paradigm. This research presents a theory of memory retrieval that not only applies over a range of paradigms but also deals with experimental data in greater depth and more detail than competing models. The theory provides a rationale for relating…

A processing model is presented that deals explicitly with both the text-comprehension and problem-solving aspects of word arithmetic problems. The model simulates construction of cognitive representations at various levels, distinguishes several information processing steps, and analyzes processing requirements that differ among types of…

A model of mental representations is developed and shown to provide a framework for interpreting research. The content of awareness is characterized as a model of the world capable of simulating future events, anticipating present events, and thereby formulating appropriate actions. Properties of awareness and of underlying processes are…

Constraint on syntax may be reflected in the transient processing demands of lexical retrieval suggesting syntactic-lexical processing interaction. The syntactic structure of utterances appears sensitive to the accessibility of lexical information with more accessibility occurring earlier in sentences. Models of interactions within a…

Two stages of skill development are: declarative (facts are interpreted) and procedural (knowledge is embodied in skill procedures). Knowledge compilation moves skills from the declarative to procedural stage in subprocesses of composition, which collapses sequences of productions into single productions, and proceduralization, which embeds…

A model for the internal representation of pitch sequences in tonal music is advanced. Pitch sequences are retained as hierarchical networks. At each level, elements are organized as structural units, in accordance with laws of figural goodness. Processing advantages of the system are discussed. (Author/BW)

Attempts to point out some serious empirical problems with the theory recently put forth by Carpenter and Just (1975) as an account of the mental processes involved in sentence-picture verification tasks. (Author/RK)

The technique for examining the time course of information processing developed by D. E. Meyer et. al. (1988) is analyzed. Research is provided, which suggests that this new method gives important qualitative support to some stochastic models and quantitative support to the continuous diffusion model of information processing. (SLD)

Capacity limitations in absolute judgment tasks are discussed in relation to information theory. Information theory can provide a quantitative way of resolving questions about limitations on the amount of information we can receive and the process of recoding. (SLD)

Six experiments involving 155 adults studied whether lexical entry for derivationally suffixed and prefixed words is morphologically structured, and how this relates to the semantic and phonological relationship between stem and affix. Results with 155 adults suggest that the morpheme is the basic unit in which the lexicon is organized. (SLD)

A model is presented that describes four types of emotion-activating systems, three of which involve noncognitive information processing. The four systems are neural, sensorimotor, motivational, and cognitive. They may be seen as a loosely organized hierarchical arrangement, operating under a number of constraints. (SLD)

Because models with dual-route architecture can explain six identified basic facts about reading, the authors suggest that this remains the workable architecture for any tenable model of reading and learning to read. The dual-route cascaded model, a computational version of the dual-route model, is described. (SLD)

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…

The process-dissociation equations (L. Jacoby, 1991) have been applied to results from inclusion and exclusion tasks to derive quantitative estimates of the influence of controlled and automatic processes on memory. This research has provoked controversies (e.g., T. Curran & D. Hintzman, 1995) regarding the validity of specific assumptions…
