What am I doing in Timbuktu: person-environment picture recognition for persons with intellectual disability.

The team showed photos to people with intellectual disability. Some photos showed the person in a place they knew. Others showed the person in a strange place. They also showed photos of other people in both places.

They asked who was in each picture. They wanted to see which mix of person and place was easiest to name.

People named themselves fastest when they stood in a familiar spot. They also named friends fastest when the friend stood in a new spot. The level of disability did not change this pattern.

Recognition was worst when self appeared in a strange place or when a friend appeared in a well-known place.

McCann (1981) cut the background out of photos. That trick helped teens with severe ID match photos to real objects. H et al. kept the full scene but swapped who was in it. Both studies say the same thing: control what surrounds the face.

Gutierrez et al. (1998) found line drawings beat photos for quick matching. H et al. show photos still work if you pair them right. Use drawings for speed; use photos for rich context.

Roche et al. (1997) saw many adults could not choose from pictures at all. H et al. give a fix: start with self-plus-familiar-place photos. That pair gives the strongest recognition boost.

When you build an AAC book, put the learner’s own photo in places they know—home, classroom, lunch table. Put photos of staff or peers in new spots like the zoo or clinic. This simple swap can cut teaching time and reduce frustration during early phases.
