THE DEVON ETV SERVICE

The Devon Educational Television Service was established more than 10 years ago by the former Plymouth Educational Authority. In the production of its own television programmes the aim is to avoid competition with BBC or IBA and to concentrate on topics with a local flavour or to augment national programmes with local material. The provision of material on video cassettes is a service now covering the whole country, as is the 35mm slide, slide/tape and multi‐media pack service. Recent examples give some idea of the range of subjects covered.

Audio tapes are produced in co‐operation with several county advisory teams. Films produced for local needs have found national and international markets. Active support is given to CSE Mode 3 studies in film and television. A working party set up to examine the role of DETVS found that the Service has become an integral and valuable part of the resource network of the county     

Sensory integration in the learning of aiming toward "self-defined" targets

This study aimed at supporting the specificity of learning hypothesis, when aiming was based on internal cues, as directing the hand toward a "self-defined" target location. Participants practiced modest (20 trials) or intensive (720 trials) training with visual and proprioceptive information or proprioceptive information only. Pretests and posttests were performed in sensory conditions that did or did not match the training condition. Results showed that dynamic visual cues played a dominant role at the beginning of the task, and an intensive practice resulted in increased accuracy of kinesthetic information and efferent mechanisms of motor responses. These results have implications with regard to motor learning conceptions and training as a function of the task constraints.
