The role of observing and attention in establishing stimulus control.

Dinsmoor (1985) wrote a theory paper. It says watching is a learned response. When a learner looks at the right thing, that act itself gets reinforced.

The paper pulls data from pigeon labs. It uses those data to explain why kids with autism sometimes fail to tell two pictures apart.

The idea: if you boost looking time, stimulus control grows. More looks equals faster discrimination.

The paper lists puzzles this solves. It covers the feature-positive effect, peak shift, and steep generalization curves.

KELLEHEBERRYMAELLIOTT et al. (1962) showed pigeons will peck a key just to see the upcoming colors. Dinsmoor (1985) uses that fact as the engine for all later control.

Lattal (1984) asked for new associative theories. One year later Dinsmoor (1985) answers with the observing-response frame, so the pair reads like a call and reply.

Aman et al. (1987) found control by never-reinforced trace cues. This supports A’s claim that the act of noticing, not the food, builds the stimulus function.

Bickel et al. (1991) ran a Pavlovian feature-negative test and got the same peaked gradients A explains through observing. The two studies differ in procedure but match in outcome, showing the idea crosses operant-Pavlovian lines.

You can’t reinforce attention you can’t see. Start by making the look produce something the learner wants: a brief movie clip, a tickle, a token. Once the child reliably orients to the critical picture, discrimination trials move faster and fewer errors stick. Track looks as you track correct responses; both curves should rise together.
