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…

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.

"Curiosity Corner" is an early childhood curriculum emphasizing children's language and literacy skills. It comprises two sets of 38 weekly thematic units--one for three-year-olds and one for four-year-olds. Program staff conduct daily lessons using sequential daily activities. One study of "Curiosity Corner" meets the What…

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…

This paper presents a temporal sequence memory based on the circuit configuration of the dentate gyrus of the mammalian hippocampus. (Author)

Data indicate that the Visual-Sequential Memory subtest of the ITPA and the Knox Cube Test measure different aspects of visual-sequential memory ability. (KW)

Learning packages allow students to cook up their own educational recipes without having to stew about deadlines. (RA)

Cumulative teaching, in which it is made certain that a child acquires one competency before proceeding to another of the same type, is described in terms of assumptions, main ideas, and its application to phonics, vocabulary, and basic addition for learning disabled students. (CL)

The method of scoring is used to obtain maximum likelihood estimates of the parameters in White and Clark's (EJ 075 122) learning hierarchy validation model. From the proportion of the population possessing only the superordinate skill in a pair of hierarchical skills, and its variance, the hypothesis of inclusion is tested. (Author/CTM)

Discussion of constructivism that is based on concerns raised in an earlier issue focuses on demands placed on the learners. Three areas are explored: (1) cognitive complexity; (2) task management, to help sequence students through a learning experience; and (3) learners "buying in" to the constructivist agenda of the instruction. (10…
