  • Title: Haptic attention and visual transfer by mentally retarded and nonretarded individuals.
    Author: Tomiser JM, Hollis JH, Monaco GE.
    Journal: Am J Ment Defic; 1983 Jan; 87(4):448-55. PubMed ID: 6829623.
    Abstract:
    Four mentally retarded and four nonretarded adolescents learned compound discriminations in the haptic (touch) modality using Ray's (1969) conflict-compound procedure. Reinforcement history was controlled so that prior reinforcement contingencies were unchanged for one element and reversed for the other element of a compound (two-element) stimulus during discrimination training. Consistent with Huguenin and Touchette's (1980) results in the visual modality, our retarded subjects evinced selective attention effects in posttraining tests conducted in the haptic modality. Results with nonretarded subjects similarly indicated that they had selectively attended to only one element of a conflict-compound stimulus during compound discrimination training. Visual transfer tests revealed that for most individuals the effects of conflict-compound discrimination training transferred from the haptic to visual sensory modalities. Results were discussed in terms of selectivity of attention to nonredundant stimulus elements as an effective strategy for discrimination learning rather than a perceptual deficit.
