Samenvatting
The authors' assignment was to review the January 1993 issue of the Journal of the Experimental Analysis of Behavior (JEAB) and identify papers or topics that might be of particular interest to individuals who work primarily on applied problems. As they reviewed the papers, it became clear that all of them touched on topics of general interest and contained provocative implications for applied issues. This paper focuses on a single theme that emerged from considering several papers as a group: behavioral interventions produce collateral effects, but prediciting those effects in applied work will be complicated bevuase of interactions aming reinforcer types.
