Responds to Ellis (1996), who claims that much of first- and second-language acquisition is sequence learning and can be explained in terms of connectionist theory. This article does not disagree with the substance of Ellis's article but rather the extent to which his model can be applied to many aspects of natural languages. (six references) (CK)

Examined implicit learning ability in 6- and 10-year olds and adults as assessed by a serial reaction-time task, along with retention of knowledge after one week and explicit knowledge developed by children. Found no age-related difference in serial reaction-time performance, consistent with the idea that implicit learning abilities may be…

In a question and answer advisory, the author gives advice to a preschool teacher working with a child who is having difficulties with sequencing, or the ability to put together a purposeful pattern of action, behavior, ideas, or thoughts. The author advises that through careful observation and appropriate learning opportunities, the children's…

Target location probability was manipulated in a visual search task. When the target was twice as likely to appear on 1 side of the display as the other, manual button-press response times were faster (Experiment 1A) and first saccades were more frequently directed (Experiment 1B) to the more probable locations. When the target appeared with equal…

Sequence knowledge acquired by repeated exposure to targets in a speeded localization task was studied in 3 experiments that sought to test A. Destrebecqz and A. Cleeremans's (2001, 2003) claim that, under certain circumstances, the expression of such sequence knowledge cannot be brought under intentional control. In Experiment 1 participants were…

This paper proposes a genetic development of the concept of limit of a sequence leading to a definition, through a succession of proofs rather than through a succession of sequences or a succession of epsilons. The major ideas on which it is based are historical and depend on Euclid, Archimedes, Fermat, Wallis and Newton. Proofs of equality by…

Behavior analysts have offered accounts of the behavior involved in matching to sample and delayed matching to sample. But until recently have not offered a behavioral analysis of generalized matching-to-sample. The concept of joint control, however, seems especially suited to such an analysis The present study used a joint-control procedure to…

A simple proof to some known results on the convergence of linear recursive sequences with nonnegative coefficients is given, using the technique of monotone convergence.

Introduction: Innovative technology has led to high-precision radiation therapy that has dramatically altered the practice of radiation oncology. This qualitative study explored the implementation of this innovation into practice from the perspective of the practitioners in a large academic radiation medicine program and aimed to improve…

Competence in algebra is linked to access to higher education, employment in better-paying jobs, and, increasingly, the ability to earn a high school diploma. For many students with learning disabilities, developing proficiency in algebra represents a challenging, but necessary goal. Teachers of students with learning disabilities need access to…

In two experiments, pupils in the primary grades were given concept attainment tasks. (Author)

This study tested the hypothesized relationship between overt sensorimotor ordering experiences and relational responding in preschool children. (Author/CS)

The focus in this analysis is on three theories of the relationships among reading comprehension skills primarily relating to the skills used in reading, not to the process or to the instructional procedures used for reading, as differentiated by Robinson. Consideration is given to three factors: (1) the existing need for theories and models in…

A strategy for investigating which individual difference variables have transfer value at various stages of acquiring effective reading skills was discussed. Definitions of basic human abilities, including intrinsic and extrinsic individual differences were reviewed. In examining the required subskills in the reading process, it was pointed out…
