Emergent Tact Control Following Stimulus Pairing: Comparison of Procedural Variations

We examined emergent tact control following stimulus pairing, using 2 different stimulus presentation arrangements. In the word-first condition, presentation of the auditory stimulus preceded the visual stimulus, and in the image-first condition, the visual stimulus preceded the auditory stimulus. E...

Zusammenfassung:We examined emergent tact control following stimulus pairing, using 2 different stimulus presentation arrangements. In the word-first condition, presentation of the auditory stimulus preceded the visual stimulus, and in the image-first condition, the visual stimulus preceded the auditory stimulus. Eight children (2–5 years old) participated. In Experiment 1 , 4 children were exposed to 3 sessions in each condition with a new set of stimuli in each session. In Experiment 2 , 2 of the same children received repeated exposure to the same stimulus sets. Experiment 3 , with new participants, was identical to Experiment 1 , except visual and auditory stimuli overlapped during the presentation. Postsession probes documented emergent stimulus control over 1 or more vocal responses for 7 of the 8 participants. Participants were more likely to make echoic responses with the visual stimulus present in the word-first condition; however, emergent tact control was unaffected by the order of the stimulus presentation. Additional research is needed on stimulus-pairing procedures and on the role of echoic responding in emergent tact control.
