Halberda, Justin – Cognitive Psychology, 2006
Many authors have argued that word-learning constraints help guide a word-learner's hypotheses as to the meaning of a newly heard word. One such class of constraints derives from the observation that word-learners of all ages prefer to map novel labels to novel objects in situations of referential ambiguity. In this paper I use eye-tracking to…

Walsh, Matthew M.; Anderson, John R. – Cognitive Psychology, 2009
In two experiments, we studied how people's strategy choices emerge through an initial and then a more considered evaluation of available strategies. The experiments employed a computer-based paradigm where participants solved multiplication problems using mental and calculator solutions. In addition to recording responses and solution times, we…

Sanborn, Adam N.; Griffiths, Thomas L.; Shiffrin, Richard M. – Cognitive Psychology, 2010
A key challenge for cognitive psychology is the investigation of mental representations, such as object categories, subjective probabilities, choice utilities, and memory traces. In many cases, these representations can be expressed as a non-negative function defined over a set of objects. We present a behavioral method for estimating these…

Hitch, Graham J. – Cognitive Psychology, 1978
Two simple quantitative models were derived from a series of experiments which explored the role of information storage in working memory when performing mental arithmetic. The decay model is a tractable analysis of a complex task which assumes a decay process in working storage. Similar analyses are recommended for problem solving activities…

Roth, James D.; Kosslyn, Stephen M. – Cognitive Psychology, 1988
Two experiments (N=36) using a new, objective methodology for measuring relative image generation time demonstrate that images of three-dimensional objects evolve a part at a time. It also appears that the images are generated in a near-to-far sequence. Results are discussed in terms of computational and ecological considerations. (TJH)
