This research examined the effects of bimodal audiovisual and unimodal visual stimulation on infants' memory for the visual orientation of a moving toy hammer following a 5-min, 2-week, or 1-month retention interval. According to the intersensory redundancy hypothesis (L. E. Bahrick & R. Lickliter, 2000; L. E. Bahrick, R. Lickliter, & R. Flom,…

Intersensory redundancy can facilitate animal and human behavior in areas as diverse as rhythm discrimination, signal detection, orienting responses, maternal call learning, and associative learning. In the realm of numerical development, infants show similar sensitivity to numerical differences in both the visual and auditory modalities. Using a…

Two experiments tested predictions of the hemispheric coactivation model for redundancy gain (J. O. Miller, 2004). Simple reaction time was measured in divided attention tasks with visual stimuli presented to the left or right of fixation or redundantly to both sides. Experiment 1 tested the prediction that redundancy gain--the decrease in…

College students viewed a short multimedia PowerPoint presentation consisting of 16 narrated slides explaining lightning formation (Experiment 1) or 8 narrated slides explaining how a car's braking system works (Experiment 2). Each slide appeared for approximately 8-10 s and contained a diagram along with 1-2 sentences of narration spoken in a…

Experiments within the microgenetic paradigm provide an assessment of the role of stimulus structure and, inferentially, of cognitive structure on perception. Two experiments investigating the effect of redundancy (structure) in written language on visual perception are reported. Seven-letter arrays differing in percentage of redundancy were…

Experiment demonstrates that the reinforcing efficacy of visual feedback is related to its degree of redundancy. (WY)

Study supported by the Research and Development Center for Learning and Re-Education, University of Wisconsin, pursuant to contracts with the U.S. Office of Education.

Partial pictures facilitated performance when presented with verbal information, but not when presented with the test questions. Sentence repetition facilitated performance only on questions presumed to reflect relatively shallow information processing. (Author/STS)

Examines effects of audio and visual redundancy on recall and story understanding in television news. Indicates that college students who viewed voice-over news stories varying in amount of redundancy showed higher auditory recall and story understanding in the high-redundancy condition than in the lower redundancy conditions. Visual recall shows…

Information presented concurrently and redundantly to 2 or more senses (intersensory redundancy) has been shown to recruit attention and promote perceptual learning of amodal stimulus properties in animal embryos and human infants. This study examined whether the facilitative effect of intersensory redundancy also extends to the domain of memory.…

The ability to allocate attentional resources to relevant aspects of a stimulus event is a critical skill needed for efficient information processing. Evidence suggests that this ability to focus on relevant information without interference is dependent on the nature of the stimulus structure of the information to be processed. To test the…

Describes three experiments designed to determine whether grapheme-to-phoneme rules are automatically applied when a word pattern is encoded. Concludes that grapheme-to-phoneme translation is a natural response to written words, at least when naming is required, and that mediation by visual mechanisms can be ruled out. (Author/MES)
