The unit of selection: what do reinforcers reinforce?

Article Abstract:

The effects of the reinforcers on behavior can be demonstrated under conditions in which the antecedents of behavior are not identified. Discriminative control of responding is inevitable and that the manipulated antecedents of behavior are typically environmental events amenable to experimental analysis and may include covert events as well. Such views trigger debates on whether control by antecedents is inescapable, including cases wherein the antecedents could not be manipulated.

Time without clocks

Article Abstract:

A critique on Staddon and Higa's research on timing intervals in animals is presented. Both argue that the capacity to time events is based on the principles of memory and not from a internal device for measuring the duration of the events. Their multiple-time-scale model is parsimonious, agrees with experimental data, can have widespread use and is evolutionary plausible. Both have made a big step in presenting an economical and generalized theory of operant behavior.
