Summation of reinforcement rates when conditioned stimuli are presented in compound
Published 2011-10-01Three experiments used delay conditioning of magazine approach in rats to examine the summation of responding when two conditioned stimuli (CSs) are presented together as a compound. The duration of each CS varied randomly ...Open AccessArticle -
Response Rate and Reinforcement Rate in Pavlovian Conditioning
Published 2011-10-01Four experiments used delay conditioning of magazine approach in rats to investigate the relationship between the rate of responding, R, to a conditioned stimulus (CS) and the rate, r, at which the CS is reinforced with ...Open AccessArticle -
Elemental Representations of Stimuli in Associative Learning
Published 2006-01-01This paper reviews evidence and theories concerning the nature of stimulus representations in Pavlovian conditioning. It focuses on the elemental approach developed in Stimulus Sampling Theory (Atkinson & Estes, 1963; Bush ...Open AccessArticle -
The arguments of associations
Published 2010-01-01This chapter considers associative solutions to “non‐linear” discrimination problems, such as negative patterning (A+ and B+ vs AB‐) and the biconditional discrimination (AB+ and CD+ vs AC‐ and BD‐). It is commonly assumed ...Open AccessBook chapter -
An attention modulated associative network.
Published 2010-01-01We present an elemental model of associative learning that describes interactions between stimulus elements as a process of competitive normalization. Building on the assumptions laid out in Harris (2006), stimuli are ...Open AccessArticle
