The attractiveness of computer-based tests (CBTs) is due largely to their capability to expand the ways we conduct testing. A relatively unexplored application, however, is actively using the computer to reduce construct-irrelevant variance while a test is being administered. This investigation introduces the effort-monitoring CBT, in which the…

This contribution describes a new laboratory experience that improves medical students' learning of chronobiology by introducing them to basic chronobiology concepts as well as to methods and statistical analysis tools specific for circadian rhythms. We designed an autorhythmometry laboratory session where students simultaneously played the role…

This study investigated the perception of place and secondary articulation contrasts in different syllable positions by Russian and Japanese listeners. The consonants involved in the study were the Russian plain (velarized) and palatalized labial and coronal voiceless stops in syllable-initial and syllable-final positions at word boundaries. The…

Nine-ten-and twelve-year-old children (N = 75) read aloud dominant, subordinate or ambiguous bias sentences (N = 120) that ended in a homonym (BALL). After the sentence (1,000 ms), children read aloud targets that were related to the dominant (BAT) or subordinate (DANCE) meaning of the homonym or control targets. Participants were also divided…

This study examined the effects of response time and message content on the growth patterns of discussion threads in computer-supported collaborative argumentation. Event sequence analysis was used to measure response times between threaded messages and responses containing arguments, evidence, critiques, evaluations, and other comments from…

The effect of different instructional variables on students' academic responding time was the focus of the current study. A total of 54 students from 10 classrooms in 5 suburban elementary schools served as subjects. In each school, six students were randomly selected from each of two classrooms, resulting in a group of 22 third graders and 32…

Research studies in science education have revealed that wait-time, the duration of teacher and student pauses in questioning dialogue, is an important variable in teaching. In this study, discussion materials were gathered, from 4 groups of 10 teachers, each week for a semester. The groups were defined as: (1) comparison group; (2) instruction in…

Because analyses of reaction-time data are sensitive to aberrant observations and violations of statistical assumptions, a new approach is suggested. In this empirical approach, one applies the same criteria to the problem of selecting a statistical method as one uses to select among alternative experimental procedures. Six criteria are presented…

Visual recognition, navigation, tracking, and imagery are posited to involve some of the same types of representations and processes. The first part of this paper develops a theory of some of the shared types of representations and processing modules. The theory is developed in light of neurophysiological and neuroanatomical data from non-human…

Five considerations of a comprehensive configuration to carry out computer-based instructional management are described. Included are data communications networks, loading/distribution of data processing operations and Instructional Management System functions, response time, computer software, and flexibility. The need for such a configuration is…

The problem posed by this study was to determine a method of presenting information that would maximize learning, by taking into account the learner's conceptual tempo, one aspect of his cognitive style. Specifically, this study investigated the possible interaction effects of the learner's impulsive-reflective disposition with the rehearsal part…

This study extends previous research done on the impulsivity-reflection dimension whereby it was determined that children who are impulsive tend to report the first response that occurs to them, while reflective children delay before answering (considering the alternative solutions to problems with high response uncertainty); and that…

Four moderately mentally retarded students, aged 8-13, were taught to read food words found in grocery stores, using constant time delay or system of least prompts procedures. Both strategies produced criterion-level performance in training and other settings, but the constant time delay procedure was more efficient. (Author/JDD)

This study demonstrated an aptitude-strategy interaction in linear syllogistic reasoning; specifically, that the efficiency of each of four alternative strategies for solving linear syllogisms would depend on subjects' verbal and spatial abilities. The four strategies, as well as research methods in aptitude-treatment interaction, are discussed.…

Describes a mispronunciation detection task, in which listeners' sensitivity to deviations in speech is measured by their pressing a button upon hearing a mispronounced word in lists or sentences. Notes that reaction times and miss rates indicate the effects of position of a misplaced phoneme in a word, the size of the phonemic deviation, lexical…
