Significant apparatus developments from the history of comparative psychology are reviewed, including the contemporary trend toward computer use in research with nonhuman animals. It is argued that milestone apparatus served not only to open new lines of inquiry but also to shape or delimit the nature of the answers that were obtained.
Hardware and software modifications are presented that allow for collection and recognition by a Commodore computer of spoken responses. Responses are timed with millisecond accuracy and automatically analyzed and scored. Accuracy data for this device from several experiments are presented. Potential applications and suggestions for improving recognition accuracy are also discussed.
A visual half-field presentation technique was used to assess hemispheric asymmetries in young, language-deficient, retarded children who had been taught a nonspeech graphic symbol system. Unlike most tachistoscopic and dichotic listening methods, the present method did not require verbal instruction or verbal responses. In addition, the subjects' explicit understanding of the need to fixate visually prior to stimulus presentation was not necessary. Meaningful graphic symbols were recognized more accurately when presented to the hemisphere associated with the dominant eye and hand. Recognition of meaningless symbols was best when they were presented to the nondominant hemisphere. There was a significant hemispheric specialization effect similar to what would be expected in older, normal subjects using traditional methods.
