Learning about food: starlings, skinner boxes, and earthworms

Article Abstract:

An operant-laboratory study was conducted to investigate the ability of European starlings, Sturnus vulgaris, to learn to respond adaptively to the problem of foraging on patchily distributed prey in an uncertain space was conducted. Results showed that starlings can easily learn to adaptively respond to the changing range of spatial space exhibited by even a single prey species. Data suggest that starlings adjust their behavior to efficiently facilitate preying in patches of an uncertain setting. Data also unveils the importance of studying foraging behavior based on an ecologically informed operant-laboratory approach.

Modeling modeling

Article Abstract:

A critique on Staddon and Higa's research on timing intervals in animals focuses on the relative merits of the Poisson pacemaker of the scalar expectancy theory (SET) and multiple-time-scale (MTS) model. The former is the mathematical model of the worst possible pacemaker. However, the accuracy of the SET will improve when the Poisson pacemaker is replaced with a more accurate oscillator. However, MTS could even be worse than the Poisson pacemaker. MTS uses a series of small models of temporal intervals whose accuracy decreases exponentially with the interval to be timed.
