01Research in Context

01

What this study did

Poulson (1998) wrote a tribute to Ellen P. Reese after she passed away.

The paper recalls how Reese ran the Keller–Schoenfeld lab at Mount Holyoke College.

It shows how she trained students to respect both human and animal behavior.

02

What they found

The article found that Reese’s teaching style left a lifelong mark on her students.

Her mix of warmth and exact lab standards created new behavior analysts for decades.

03

How this fits with other research

Hineline (2022) extends Reese’s legacy by giving today’s teachers story-based tools to teach behavior-analysis history.

Geurts et al. (2008) built a big list of 116 teaching articles that put Reese’s lab ideas into print for college instructors.

Catagnus et al. (2025) and Jimenez‐Gomez (2024) update the mentorship theme by adding cultural humility and antiracist practice to the Reese model.

Together these papers show a chain: Reese started respectful mentoring, and later authors keep adding new layers for modern classrooms.

04

Why it matters

You can copy Reese’s respect-first style in your own supervision. Pair firm lab standards with genuine care for your trainee’s perspective. Add the newer cultural checks from Catagnus et al. (2025) and Jimenez‐Gomez (2024) to keep the legacy current.
