Safe periods both explain and need explaining.

Warburg (2001) wrote a theory paper about safe periods. Safe periods are short times when nothing bad happens. The paper says these quiet spells may act like rewards in avoidance learning.

The author liked Dinsmoor’s old idea but said it still has holes. The piece asks what exactly makes a safe period feel good.

The paper finds no new data. It simply claims that safe periods can reinforce avoidance, yet the full story is missing. The main point: we need a clearer rule for how a pause from threat becomes a reinforcer.

LeFrancois et al. (1993) also tweaked timing theory. They added a ‘transition-lag’ knob so the model fits real data better. Both papers fix old ideas, but R et al. give a tool while M only flags the gap.

Pilowsky et al. (1998) tested changeover delays. They showed that different delay types change local response bursts. Their work backs M’s hunch that the way time is carved by contingencies matters.

Baum (2021) goes wider. He says behavior is a smooth stream, not discrete presses. M’s safe period fits that stream view: the reinforcer is a slice of time, not a pellet.

If quiet windows can reward behavior, you can program them in treatment. For example, give a brief ‘no-demand’ break right after a client uses a coping request. The break itself may strengthen the request, just like food would. Track seconds of peace and see if the skill grows.
