Second-order conditioning in a licking-based conditioned suppression situation

Second-order conditioning in Drosophila.

Associative conditioning in Drosophila melanogaster has been well documented for several decades. However, most studies report only simple associations of conditioned stimuli (CS, e.g., odor) with unconditioned stimuli (US, e.g., electric shock) to measure learning or establish memory. Here we describe a straightforward second-order conditioning (SOC) protocol that further demonstrates the flex...

Second-Order Conditioning and Conditioned Inhibition: Influences of Speed versus Accuracy on Human Causal Learning

In human causal learning, excitatory and inhibitory learning effects can sometimes be found in the same paradigm by altering the learning conditions. This study aims to explore whether learning in the feature negative paradigm can be dissociated by emphasising speed over accuracy. In two causal learning experiments, participants were given a feature negative discrimination in which the outcome ...

Second-order conditioning of human causal learning

This article provides the Wrst demonstration of a reliable second-order conditioning (SOC) eVect in human causal learning tasks. It demonstrates the human ability to infer relationships between a cause and an eVect that were never paired together during training. Experiments 1a and 1b showed a clear and reliable SOC eVect, while Experiments 2a and 2b demonstrated that Wrst-order extinction did ...

Discrimination learning in a verbal conditioning situation.

Forward and backward second-order Pavlovian conditioning in honeybees

Second-order conditioning (SOC) is the association of a neutral stimulus with another stimulus that had previously been combined with an unconditioned stimulus (US). We used classical conditioning of the proboscis extension response (PER) in honeybees (Apis mellifera) with odors (CS) and sugar (US). Previous SOC experiments in bees were inconclusive and therefore, we attempted to demonstrate SO...
