Teaching complex intraverbal responding to children with autism spectrum disorder (ASD) can be challenging and often requires careful programming. Divergent and convergent multiple control are particularly important elements to incorporate into intraverbal training programs, as well as procedures to ensure responding is under control of both…

The worldwide rise in obesity makes this the first non-infectious epidemic in human history. The rapid increase is, in fact, influenced more by environment than biology. In an effort to halt the trend, Quebec has launched a major awareness-raising campaign that focuses on healthy environments and targets stakeholders in schools, municipalities,…

An investigation of the efficacy of covert negative reinforcement (Ascher and Cautela, 1972) was replicated. Thirty Ss were randomly assigned to one of three groups. Ss in the experimental group were trained to imagine a noxious scene, then to shift to the image of a ringing bell. During the test phase, the word "bell" was used to reinforce over-…

The purpose of this investigation was to assess biofeedback (BF) and progressive muscle relaxation (PMR) and placebo-control training by means of a post-training transfer test. The subjects for the research were 30 women. Initial tests consisted of measuring the electromyographic response of the frontalis muscle of the forehead to stress. After…

A study of the acquisition of mands (requests) and tacts (labels) relating to food and eating utensils in three individuals with severe mental retardation revealed that responses acquired as tacts did not readily occur as mands, but spontaneous manding was developed through a stimulus control transfer procedure. (MSE)

We examined some conditions under which a response acquired as a tact might facilitate the establishment of a mand. We taught 3 participants with developmental disabilities to tact the items ranked highest and lowest in a preference assessment and subsequently tested to see if the responses occurred as mands. All participants manded for the highly…
