Recent theoretical developments in the field of absolute identification have stressed differences between relative and absolute processes, that is, whether stimulus magnitudes are judged relative to a shorter term context provided by recently presented stimuli or a longer term context provided by the entire set of stimuli. The authors developed a…

This study was designed to explore the placebo-controlled effects of risperidone on cognitive-motor processes, dyskinetic movements, and behavior in children receiving maintenance risperidone therapy. Sixteen children aged 4-14 years with disruptive behavior were randomly assigned to drug order in a crossover study of risperidone and placebo for 2…

Investigated whether it took more time for first graders to answer a question if they began with a small mental image of the queried object than if they began with a normal-sized image. It was hypothesized that it would take them more time to "see" part of the smaller image. Preliminary results were consistent with this expectation. (Author/JMB)

Examined the effects of an audiovisual distractor on the visual attention paid to TV by preschool children characterized as distractible. The effectiveness of an audiovisual distractor eliciting a head turn from the TV was diminished when TV viewing had been maintained for at least 15 seconds. (PCB)

Self-administered testosterone and anabolic steroids resulted in insignificant improvement in psychomotor and motor speed tests of power athletes. This study is part of a larger study on the effects of such drugs on endocrinology, metabolism and neuromuscular functions. Methodolgy and results are discussed. (Author/JL)

An investigation was conducted to equate auditory and electrocutaneous stimuli. These equated stimuli were used in a second investigation examining neuromotor responses to stimuli of varying intensity. Results are provided. (Author/MT)

Twenty-four groups (mean age 6 years-20 years) of 12 subjects each undertook nine separate rotary pursuit tasks. Scores suggested four discrete clusters, ranked according to overall performance level. These clusters replicated exactly those derived from an earlier analysis of performance on three reaction time measures. (Author/CL)

Vocal reaction time of 16 hearing and 25 hearing impaired children (7-14 years old) in response to visually presented stimuli was measured in four tasks. Differences between normal and hearing impaired increased systematically with the phonetic complexity of the task. Hearing level and latency in the counting responses were major predictors of…

Illustrates kinds of intelligence tests, discussing factors indicating intelligence: genetics, reaction time, latency and amplitude, and variability. Lists the advantages and disadvantages of the intelligence tests mentioned. (CI)

Two experiments were conducted to identify response elements responsible for the complexity effect found by Henry and Rogers. Results suggest that, as the number of movement parts and the accuracy demands increase, programing time increases, supporting the hypothesis that response initiation time becomes longer as programing becomes more complex.…

Two studies featuring a reaction time paradigm and field linguistics supported the conjecture that dyslexia involves a central anomaly in structural linguistic capacity. (CL)

Reaction times, movement times, and static strengths of the four limbs were measured and pubertal status was assessed in males and females at ages nine, 11, 13, 15, and 17 years primarily to separate the effects of sexual maturation from the associated sex and age trends. (RC)

In this study instead of the experimenter controlling the duration of stimulus exposure, the infants' behavior was allowed to control stimulus duration. (Authors/MB)
