Foot-in-the-door Experiment

I’m trying to replicate this procedure as part of my graduate research, and I’m lost about how to go about it where I’d be able to measure latency (“reluctance”) to make the first response to the second stimulus within each trial and session.

OS: Mac OS 10.15.6
PsychoPy version: StandalonePsychoPy-2021.2.3-macOS
Standard Standalone? (y/n) y
What are you trying to achieve?:

FITD procedure. Each trial starts with a single effort stimulus appearing on a random side of the screen. The effort stimulus is either LOW, MED, or HIGH (1–9, 10–19, 20–29 pecks). After the pigeon pecks the first stimulus, there will be a 3-s delay period, and after that, the second effort stimulus appears. All pigeons are rewarded after having finished pecking the second stimulus, and after a 10-s ITI, a new trial starts.

Any help or direction would be appreciated!
