Classification of Three-Dimensional Integral Stimuli: Accounting for a Replication and Extension of Nosofsky and Palmeri (1996) with a Dual Discrimination Invariance Model
Peer reviewed Peer reviewed
Direct linkDirect link
Vigo, Ronaldo; Doan, Charles A.; Zhao, Li – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2022
The quest for determining the degree of learning difficulty associated with different types of categories has been instrumental in our understanding of human categorization behavior and, more broadly, human generalization. For instance, we now know that the topological nature of the dimensions (e.g., whether these are integral or separable) that…

Hayes, Brett K.; Stephens, Rachel G.; Lee, Michael D.; Dunn, John C.; Kaluve, Anagha; Choi-Christou, Jasmine; Cruz, Nicole – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2022
Much recent research and theorizing in the field of reasoning has been concerned with intuitive sensitivity to logical validity, such as the logic-brightness effect, in which logically valid arguments are judged to have a "brighter" typeface than invalid arguments. We propose and test a novel signal competition account of this…

Aptitude by Treatment Interactions in Computer-Assisted Word Learning by Mentally Retarded Students.
Conners, Frances A. – American Journal on Mental Retardation, 1990
The investigation of interactions between the abilities of stimulus discrimination and simple learning and two instructional variables (discrimination difficulty and degree of overlearning) with 27 mentally retarded adolescents found an interaction between stimulus discrimination and the number of words presented at one time for learning…

Stimulus Equalization: Temporary Reduction of Stimulus Complexity to Facilitate Discrimination Learning.
Peer reviewed Peer reviewed
Hoko, J. Aaron; LeBlanc, Judith M. – Research in Developmental Disabilities, 1988
Because disabled learners may profit from procedures using gradual stimulus change, this study utilized a microcomputer to investigate the effectiveness of stimulus equalization, an error reduction procedure involving an abrupt but temporary reduction of dimensional complexity. The procedure was found to be generally effective and implications for…

Review of Research on Sight Word Instruction.
Peer reviewed Peer reviewed
Browder, Diane M.; Lalli, Joseph S. – Research in Developmental Disabilities, 1991
This review of 20 years of literature on sight word instruction for individuals with handicaps examines effectiveness data for procedures teaching word recognition and comprehension. Covered are "errorless procedures," prompt elimination, stimulus fading, time delay, easy to hard discrimination, and trial and error with feedback. Two tables…
