Derived Equivalence Relations of Geometry Skills in Students with Autism: an Application of the PEAK-E Curriculum

The present study evaluated the efficacy of equivalence-based instruction (EBI) as described in the PEAK-E curriculum (Dixon, 2015) for promoting the emergence of derived geometry skills in two children with high-functioning autism. The results suggested that direct training of shape name (A) to shape property (B) (i.e., A-B relations) was effective for both participants. Following A-B training, both participants demonstrated emergent relations that are consistent with symmetry (B-A), as well as emergent shape name (A) to shape picture (C) relations that are consistent with transitivity (A-C). The results expand on existing literature by demonstrating the emergence of an A-C relation when neither A nor B stimuli were ever trained to C stimuli and illustrate the efficacy of EBI for training geometry skills.

     

Monetary Discounting of Delayed Consequences Predict Employment Nudity: Exotic Dancers Versus Waitresses

The present study examined temporal monetary discounting rates among exotic dancers, waitresses who are required to wear revealing uniforms, and waitresses at a local restaurant where revealing clothes are not part of work attire. Current findings indicate that exotic dancers and waitresses who are required to wear revealing clothing discounted significantly more than waitresses at restaurants where provocative dress is not required. These results suggest that the type of job held may predict impulsivity, with nude or risqué occupations indicating steeper patterns of overall discounting.
