While there has been extensive experimental research on haptics, less has been conducted on cross-modal interactions between visual and haptic perception and even less still on cross-modal applications in instructional settings. This study looks at a simulation on the principles of levers using both visual and haptic feedback: one group received…

The Feature Integration Theory of visual search proposed by A. M. Treisman and others (1980, 1986) is reviewed, and a modified Guided Search theory is presented in which the parallel stage guides the serial stage as it chooses display elements to process. A computer simulation illustrates the theory. (SLD)

A connectionist model, SEarch via Recursive Rejection (SERR), is presented that performs across a window defining the model's functional field. Implications are discussed, and results of 5 experiments involving 19 male and 19 female adults and adolescents that test novel predictions derived from the model are presented. (SLD)

In 4 experiments, the authors varied the extent and nature of participant movement in a virtual environment to examine the influence of action on estimates of geographical slant. Previous studies showed that people consciously overestimate hill slant but can still accurately guide an action toward the hill (D. R. Proffitt, M. Bhalla, R.…

Explores the relationship between virtual reality (VR) stimulation and perceptual equivalence. Topics include perceived realism; creating a virtual illusion; displayed realism; and VR as an instructional technology. (Author/AEF)

Self-rated sense of direction is reliably related to people's accuracy when pointing in the direction of unseen landmarks from imagined or actual perspectives. It is proposed that the cognitive substrate of accurate pointing responses is a vector representation, which is defined as an integrated network of displacement vectors. Experiment 1…

This study showed that the Elementary Perceiver and Memorizer (EPAM) can explain letter recognition phenomena earlier simulated by the connectionist Interactive Activation Model of word perception. EAPM, a model of learning and recognition in the form of a computer program, has previously explained many aspects of learning and perception. (TJH)

In educational settings, computers provide specific possibilities of visualizing information for instructional purposes. Besides the use of static pictures, computers can present animated pictures which allow exploratory manipulation by the learner and display the dynamic behavior of a system. This paper develops a theoretical framework for…
