Modification of verbal behavior of the mentally impaired elderly by their spouses.

Green et al. (1986) worked with two elderly men who had dementia. Both men showed severe problem talk such as constant cursing or repeated questions.

The team taught each wife to use differential reinforcement at home. Wives praised and chatted when their husband said nice or useful things. They looked away or stayed quiet when the man swore or repeated.

Problem talk dropped and pleasant talk rose in both couples. The wives felt calm and the men kept living at home instead of moving to a nursing facility.

The simple praise-and-ignore plan worked even though the men had brain changes from dementia.

Chock et al. (1983) said behavioral decline in older adults is reversible, not just age. R et al. proved it by showing spouses can do the work at home.

McDevitt et al. (2026) later added real-life barriers during caregiver BST. Both studies show the same theme: train the helper where the behavior happens.

Galloway (1967) used token amounts to shift kids’ choices. R et al. used social attention to shift elders’ talk. Same rule, new group and simpler reinforcer.

You can teach a spouse to run differential reinforcement in one afternoon. No clinic, no drugs, no costly gear. If nursing-home placement is on the table, try this first. Start by tracking five minutes of talk, then coach the partner to praise nice words and withhold attention for cursing or repetition. One calm spouse can keep a loved one home longer.
