This study examined the use of visual feedback (VF) by typists at various skill levels. Subjects performed typing trials under four conditions: unrestricted VF, VF for response confirmation, VF for response guidance, and restricted VF. Results suggest similar use of visual feedback by typists of different skill levels. (Author/SJL)

Author states that participation in TV becomes video feedback to teachers and parents. If radical approaches to TV become the norm, video will be the content of a new awareness that is being generated by this new visual culture. (Author)

Eight-year-old children were trained on length or weight relationships between adjacent members of a five-item series of colored objects. Visual feedback was provided. Results indicated more salient visual feedback reduced learning effort for length but not for weight comparisons. Encoding differences found in another experiment were used to…

Interplay between visual feedback and lip-positioning skill was studied among 10 normal hearing and 10 hearing impaired children (aged 5 to 14 years). In general, findings showed that, given visually displayed lip-position targets and feedback from positioning actions, children could perform accurately regardless of hearing status or prior…

Three approaches demonstrated the usefulness of visual feedback and auditory feedback to improve the on-task behavior and academic productivity of deaf multihandicapped adolescents. The approaches feature inexpensive portable equipment that do not require lengthy teacher training. (CL)

Infants ranging in age from six months to eight months were shown repeated instances of real object movement-disappearance-reappearance. Results suggest that the key changes in early cognitive development rest primarily upon the infant's gradual adaptation of old responses through encounters with new events--rather than upon the acquisition of…

Seventy-five subjects were trained on a pursuit rotor for 10 trials, with ambient illumination from a strobe light flashing at frequencies of either 2,5,10,15, or 20 per second. A transfer trial followed, with a strobe flashing frequency of 10 per second for all subjects. Results supported hypotheses derived from Adams' closed-loop theory of motor…

A description is given of an experiment investigating the applicability of a cybernetic theory in teaching children psychomotor skills. Results showed a learning effect in copying for younger subjects, in tracing for older subjects, and in tracking for all subjects. (GK)

The influence of visual signals (echo and reverberation) on speech fluency in 60 stutterers and nonstutterers was examined. Visual signals were found to exert a corrective influence on the speech of stutterers but less than the influence of acoustic stimuli. Use of visual signals in combination with acoustic and tactile signals is recommended. (DB)

INSTRUCTIONAL AND EQUIPMENT CONSIDERATIONS IN THE DESIGN OF THE STUDENT MACHINE INTERFACE, THE POINT OF CONTACT OF A LEARNER WITH AN EDUCATIONAL SYSTEM DISPLAY, ARE DISCUSSED. INSTRUCTIONAL ASPECTS ARE CONSIDERED WITH RESPECT TO THE REQUIREMENTS FOR THE INDIVIDUALIZATION OF THE LEARNING ENVIRONMENT, THE SEQUENCING OF INSTRUCTIONAL STEPS, AND…

Subjects from kindergarten-age to adult participated in four experiments. In order to view the stimuli, subjects in three experiments activated lights in viewing boxes; in the fourth experiment, stimulus fixations were measured using a corneal reflection technique. Results supported the view that visual observing is controlled by cognitive…

A study of elementary school students investigated the effects of immediate feedback during a spelling pretest compared to the usual delayed feedback after dictation of an entire word list. Results indicated a small degree of difference between methods. (Author/DF)
