There is ongoing debate about children's ability to use subsequently acquired language to describe preverbal experiences. This issue was addressed experimentally in this investigation using a novel paradigm. Two-year-old children who lacked color words were individually taught to activate a bubble machine by selecting a particular color of bubble…

Three- to six-year-old children (n=28) and adults (n=46) participated in a two-dimensional search task that included geometry and feature conditions. During each of 24 trials, participants watched as a cartoon character hid behind one of three landmarks arranged in a triangle on a computer screen. The landmarks and character then disappeared and…

Task analysis is the process of identifying all things that individuals must accomplish to satisfactorily complete an activity or course of instruction. This bibliography lists task analysis documents related to curriculum or course development, or training program development. Five abstracting services were searched from their first publication…

In this study, the number of alternatives for an extended arm swing was varied in order to test two memory drum predictions regarding movement refractoriness. (JS)

This paper demonstrates that in a toppling dive (1) a 1:1 ratio exists between the rotational speed of the diver immediately before and after the take-off and (2) the take-off angle as defined by Page is approximately 50 percent. (Author)

A 32-item test battery was administered to 154 male and female elementary school students to describe the static balance ability of 6- to 9-year-old children. Body position, visual use, and one-footed static base of support were found to affect subjects' balance performance. (Author/RH)

Outlines some of the fundamental concepts of skilled behavior and describes a practical approach to the analysis of nonrepetitive tasks. Four figures. (LY)

Syntactic priming of Chinese nouns and verbs was investigated in word recognition and production. Disyllabic compound words were presented after syntactically congruent, incongruent, or neutral auditory contexts, with a zero delay between offset of the context and onset of the target. Significant priming was observed in both tasks, including…

Discusses and explains relationships between performance technology and instructional development. Highlights include a concept analysis of performance technology; types of evaluation; instructional development as a subset of performance technology; front-end analysis; sample performance technology interventions; and differences between…

Presents remarks on constructivism that are based on a discussion in an earlier issue. Topics addressed include the role of theory in the instructional design process; the construction of knowledge; differences between objectivists and constructivists; knowledge representation; entry behaviors and task analysis; and instructional systems…

Go/no-go tasks seem to provide a simple marker of inhibitory development in young children. Children are told to respond to one stimulus on go trials but to make no response to another stimulus on no-go trials; responding on no-go trials is assumed to reflect a failure to inhibit the go response. However, there is evidence to suggest that a type…

The authors tested the hypothesis that with adequate practice, people can execute 2 cognitive operations in working memory simultaneously. In Experiment 1, 6 students practiced updating 2 items in working memory through 2 sequences of operations (1 numerical, 1 spatial). In different blocks, imperative stimuli for the 2 sequences of operations…

Simon effects might partly reflect stimulus-triggered response activation. According to the response-discrimination hypothesis, however, stimulus-triggered response activation shows up in Simon effects only when stimulus locations match the top-down selected spatial codes used to discriminate between alternative responses. Five experiments support…

The paper is a reflective account of the design and implementation of mathematical tasks that evoke uncertainty for the learner. Three types of uncertainty associated with mathematical tasks are discussed and illustrated: "competing claims," "unknown path or questionable conclusion," and "non-readily verifiable outcomes." One task is presented in…
