Computational models of classical conditioning have made significant contributions to the
theoretic understanding of associative learning, yet they still struggle when the temporal …

Four experiments compared the extinction of responding to a continuously reinforced (CRf)
conditioned stimulus (conditional stimulus [CS]) consistently reinforced on every trial, with …

The nature of the operations that support learning should be evident in the form or shape of
the learning curve. For example, models that describe learning as an iterative error …

Different aspects of recognition memory in rodents are commonly assessed using variants of
the spontaneous object recognition procedure in which animals explore objects that differ in …

This paper presents a novel representational framework for the Temporal Difference (TD)
model of learning, which allows the computation of configural stimuli–cumulative …

The duration of a conditioned stimulus (CS) is a key determinant of Pavlovian conditioning.
Rate estimation theory (RET) proposes that reinforcement rate is calculated over cumulative …

Two experiments investigated the effect of the temporal distribution form of a stimulus on its
ability to produce an overshadowing effect. The overshadowing stimuli were either of the …

In multiple fixed interval schedules of reinforcement, different time intervals are signaled by
different environmental stimuli which acquire control over behavior. Previous work has …

In 3 experiments, rats were given nonreinforced preexposure to an auditory stimulus, after
which this stimulus and a second, novel cue were paired with food. Lower rates of …

Forty mice acquired conditioned responses to stimuli presented in a multiple schedule with
variable inter-trial intervals (ITIs). In some trials, reinforcement was preceded by a variable …
