Common response-time-based approaches for non-effortful response behavior (NRB) in educational achievement tests filter responses that are associated with response times below some threshold. These approaches are, however, limited in that they require a binary decision on whether a response is classified as stemming from NRB; thus ignoring…

A long-standing issue in the study of how people acquire visual information centers around the scheduling and deployment of attentional resources: Is the process serial, or is it parallel? A substantial empirical effort has been dedicated to resolving this issue. However, the results remain largely inconclusive because the methodologies that have…

Two experiments were designed to test a number of finite-state self-terminating memory-scanning models for choice reaction times. (Editor)

A review of some recent experiments suggested that general similarity between words might successfully function as a structural principle for semantic memory. A spatial model based on that assumption is proposed. The relation of this model to network and set-theoretic models of semantic memory is discussed, as is the relation of this model for…

A method of analyzing reaction time data in recognition memory is presented. A wide range of phenomena that any theory of recognition memory must explain is discussed. (Editor/RK)

A new theoretical analysis of the stop-signal model is proposed. Within the concepts of crude- and net-hazard functions, the nonobservable control-latency distribution can be estimated from observable reaction times. This result allows a test of the Logan and Cowan model (1984) without simplifying assumptions. (SLD)

Explains the use of pigeons in behavioral psychology research for modeling human behavior and discusses instructional objectives for humans. Topics addressed include the relationship between response rate and reinforcer rate; resistance to alternative reinforcement; choice and matching; and persistence and reinforcement. (Contains 11 references.)…

When shown a pair of digits and asked to select the larger of the two, subjects make their choice more quickly as the numerical difference between the digits increases. Presents and tests a semantic coding model that can explain this and all previous results. (Editor)

Three experiments examined what happens to reaction time to verify easy items when they are mixed with difficult items in a verification task. Subjects verification of simple arithmetic equations and sentences took longer when placed in a difficult list. Difficult sentences also slowed the verification of easy arithmetic equations.

The cascade model of information processing is compatible with the relation between time and accuracy in speed-accuracy trade-off experiments. Findings regarding the additive factors methods led to reexamination of conclusions drawn from several studies about the locus of perceptual and attentional effects on processing. (Author/RD)

Speculates on underlying processes for the reaction time variance and age differences in anticipation latency using the Visual Expectation Paradigm. Discusses the dichotomization of reactive and anticipatory behavior, limitations of longitudinal designs, drawbacks in using standard procedures and materials, and inferences that can be made…

Preschool children's problem solving processes are investigated in both direct and indirect ways. Direct investigations focus on substantive and methodological issues related to how children solve a few well defined puzzles, such as the Tower of Hanoi and the Tangram. Indirect investigations deal with related issues: U-shaped (or non-monotone)…

Longstreth's critique of Jensen's research on the relationship of IQ to individual differences in visual reaction time (RT), measured in the Hick paradigm, is said to have numerous errors of fact and interpretation, some trivial and some of theoretical importance. (Author/LMO)

Reviews the syntactic priming task, a paradigm involving the presentation of a phrasal or clausal context, followed by the presentation of a target item for lexical decision or naming. Notes that response times are faster for targets syntactically congruent with the preceding context than for incongruent targets. Outlines how to administer this…

Notes that in a typical word monitoring paradigm, subjects monitor ongoing language input for a pre-designated target word and that independent variables include the nature and position of the target word and the context in which it is embedded. Also notes that forms of this task are suitable for studies with young children and with individuals…
