This study reports changes in kindergarten students' understanding of magnets after participating in a series of hands-on, inquiry-based lessons. The lessons focused on the dipole nature of magnets and employed a visual representation of a magnet as an arrow for the kindergarten students. This dipole model was used to describe how magnets interact…

When neural events are analyzed as stimuli and responses, functional relations among them and among overt stimuli and responses can be unveiled. The integration of neuroscience and the experimental analysis of behavior is beginning to provide empirical evidence of involvement of neural events in the three-term contingency relating discriminative…

In this article, we discuss whiteboard math movies (a.k.a. mathcasts) and their applications to mathematics education. A whiteboard math (wbm) movie is a screen recording of writing plus voice and/or text explaining a mathematical concept or solving a problem. The movie is then produced to Flash movie format and distributed via CD or Internet. The…

Developmental dyslexia is defined as a disorder of learning to read. It is thus critical to examine the neural processes that impair learning to read during the early phase of reading acquisition, before compensatory mechanisms are adapted by older readers with dyslexia. Using electroencephalography-based event-related imaging, we investigated how…

This study examines preschoolers' causal assumptions about spatial contiguity and how these assumptions interact with new evidence in the form of conditional probabilities. Preschoolers saw a toy that activated in the presence of certain objects. Children were shown evidence for the toy's activation rule in the form of patterns of probability: The…

The authors argue that human sequential learning is often but not always characterized by a shift from stimulus- to plan-based action control. To diagnose this shift, they manipulated the frequency of 1st-order transitions in a repeated manual left-right sequence, assuming that performance is sensitive to frequency-induced biases under stimulus-…

Purpose: The purpose of this study was to examine children's knowledge of semantic relations. Method: In Experiment 1, the 6-year-olds, 8-year-olds, and adults participated in an object decision task. Participants in the primed group made object decisions in response to primes that were related taxonomically, thematically, or perceptually to the…

In the type of intraverbal that consists of saying the opposite of a word, two intraverbals are related to one another because the response form of each intraverbal functions as part of a discriminative stimulus for the other (e.g., "cold" in response to "name the opposite of hot," and vice versa). Moreover, the contextual cue "Name the opposite…

This study investigated the caseload characteristics and the types of intervention implemented for children with autistic spectrum disorder (ASD). A survey was developed and distributed to 75 speech-language therapists working for Special Education within the New Zealand Ministry of Education. A total of 34 surveys were completed and returned.…

Joseph, a student with autism in Ms. Mendez's inclusion kindergarten class, experienced difficulty attending during group activities. He spent a significant amount of time looking at his hands and quoting parts of his favorite videos. Attempts to engage Joseph resulted in vocal protests and, at times, mild aggression. Ms. Mendez realized that she…

This study examined the specific effects of picture and object stimuli on two types of language performance: comprehension and performance. Subjects were 48 4- and 5-year-olds who were randomly assigned to one of four groups. Groups were matched for SES, sex, and age and tested individually with one of the four measures: language comprehension…

This study investigates the role of labeling in developmental increases in picture recall. In two experiments, the memory for pictorial paired-associates of first graders or second graders, fourth graders and adults was evaluated by means of a study-test cued recall procedure. In Experiment 1, the stimulus presentation duration (on-time) and the…

The result of a number of experiemental studies of human auditory and visual information processing behavior and their possible relationship to the student pilot's acquisition of flying skill were explored in terms of a conceptual model developed for this study. The results were interpreted in terms of the potential interfering effects of the…

For research into the usefulness of attention-gaining devices in informational films, five film versions on machine shop measuring instruments were produced. These versions were termed: basic, visual relevant, visual irrelevant, sound relevant, and sound irrelevant. Attention-gaining devices were placed at the same points in all but the basic…

The purpose of this pilot study was to test the hypothesis that the mean number of correct responses to pictorial items (line drawings) would be significantly higher than the mean number of correct responses to verbal (printed word) items. The items tested were selected from the items included in a posttest administered to 33 first grade students…
