A digital simulation of a model for the processing of visual images is derived from known aspects of the human visual system. The fundamental principle of computation suggested by a biological model is a transformation that distributes information contained in an input stimulus everywhere in a transform domain. Each sensory input contributes under…

The reported research was designed to investigate the impact of learner control on performance and anxiety in a computer assisted instruction task. This, the third phase of a project, substituted pictorial mediators for mnemonic devices as the facilitating variable in an instruction program on edible plants. Four experimental groups were formed…
