This study investigated the development of the many-to-one counting strategy in 4- year-old children. In the first experiment, 52 children participated. Their development with respect to two kinds of tasks, a hidden-items task and a needed-items task, was studied over four sessions. Children (n = 28) who accurately used the many-to-one strategy in…

Several investigations have shown that young infants perceive the unity of a center-occluded object when the visible ends of the object undergo common motion but not when the object remains stationary. This study is an extension of earlier investigations on object unity in that it assesses amodal completion of stationary circles in which one half…

This paper reports on an investigation of children's (aged 3;5-9;8) comprehension of sentences containing ambiguity of prepositional phrase (PP) attachment. Results from a picture selection study (N=90) showed that children use verb semantics and preposition type to resolve the ambiguity, with older children also showing sensitivity to the…

Antecedent-Behavior-Consequence (A-B-C) recordings are often used in school settings as part of a functional assessment. A number of limitations are associated with A-B-C recordings, and a novel approach for describing data from A-B-C recordings is to compute conditional probabilities that can be graphed in the general operant contingency space to…

Writing researchers have developed various methods for investigating the writing process since the 1970s. The early 1980s saw the occurrence of the real-time computer-aided study of the writing process that relies on the protocols generated by recording the computer screen activities as writers compose using the word processor. This article…

The typical use of science notebooks is for students to record information as they complete an investigation, writing down their procedure, observations, data, results, graphs, and any other factual information pertaining to their experiment.

This article argues that the field of education and conflict is, in many ways, "stuck in its emergence" because it has yet to develop common theoretical understandings, useful analytical tools, and shared conceptual frameworks to unify and sustain a mutual endeavour by scholars working on a diverse range of topics and cases. In a…
