1 Equivalence: Connecting Concepts in Networks Efficiently Daniel C. DeRosa Behavior Analysis

2 Autism Spectrum Disorders 1 in 80 to 1 in 240 I in 110 Estimated 1 in 94 boys born in the United States (Based on CDC Report) Difficulties in: Interacting socially Building meaningful relationships Learning language Learning to read 8/21/11 DeRosa CS Presentation

3 Equivalence Paradigm Reading Comprehension (Sidman, 1971) Establishing Categories (Griffee & Dougher, 2002) Statistics (Fields et al., 2009) Braille Literacy (Toussaint & Tiger, 2010) DeRosa CS Presentation 8/21/11

4 That’s Equivalence If A = B & A = C, then B = C, and C = B, C = A, B = A
