Rapid, accurate time estimation in zebrafish (Danio rerio).

Abstract

Zebrafish were tested in an appetitive Pavlovian delayed conditioning task. After an intertrial interval of k*T s (k=11.25; T=8, 16 or 32 s), a small, translucent vertical pole was illuminated (CS) for T s. Food was presented at T/2 s. Pole-biting response latencies from CS onset were a linear function of the food delay T/2, with slope approximating unity (proportional timing), and standard deviation proportional to latency (scalar timing). Response latencies tracked changes in food delays even when they changed every other day. These findings are significant because the zebrafish genome has recently been sequenced, opening the door to studies in the genetics of interval timing.

Until my retirement in 2007, my laboratory did experimental research on learning and adaptive behavior, mostly with animals: pigeons, rats, fish, parakeets.  We were particularly interested in timing and memory, feeding regulation, habituation and the ways in which pigeons and rats adapt to reward schedules. The aim  is to arrive at simple models for learning that can help to identify the underlying neural mechanisms. I continue to do theoretical and historical work on the power law in psychophysics, operant learning, timing and memory, habituation and feeding regulation.  I have applied some of these ideas to economics and financial markets and social issues such as traffic control (Distracting Miss Daisy, The Atlantic, 2008; Death by Stop Sign) and smoking (Unlucky Strike, Private Health and the Science, Law and Politics of Smoking, with David Hockney, UBP, 2013).  A second edition of Adaptive Behavior and Learning (Cambridge UP) was published in 2016. Most recently I have published Scientific Method: How Science Works, Fails to Work, and Pretends to Work. published by Routledge in December, 2017, Unlucky Strike Second Edition, and Science in an age of unreason (Regnery, 2022).
