Between the waves: Harvard Pigeon Lab 1955-1960.

Lindsay (2002) is not an experiment. It is a memoir. The author recalls life at the Harvard Pigeon Lab from 1955 to 1960.

He tells stories of graduate students building cages, wiring relays, and running pigeons on schedules of reinforcement.

The paper finds no data. It finds memories. The lab ebbed and flowed as students arrived, finished dissertations, and left.

The author shows how daily shop talk shaped the ideas that became modern applied behavior analysis.

Busch et al. (2010) and Bailey (2008) still use pigeons today to test symmetry and equivalence. Their work extends the basic methods first hacked together in the Harvard lab.

Miller (1976) turned those same methods into matching-law equations. The memoir explains the hands-on origin of the gear that L later used to quantify reinforcer value.

Lambert et al. (2022) mirrors the memoir in one way: both describe university practicum evolution. The 1950s lab forged practitioners with solder and data sheets; the 2022 clinic does it with functional assessments and client graphs.

Reading this memoir is like peeking at your professional family tree. You see that error-counting sheets, cumulative recorders, and student arguments built the field you now use with clients. When you graph a token board or run a delay-to-graze trial, you are using tools first sketched on a Harvard bench. Remember that lineage when you train new RBTs: hands-on tinkering plus data still forge the best practitioners.
