Behavioral flexibility is a cognitive process depending on prefrontal areas allowing adaptive responses to environmental changes. Serotonin transporter knockout (5-HTT[superscript -/-]) rodents show improved reversal learning in addition to orbitofrontal cortex changes. Another form of behavioral flexibility, extradimensional strategy set-shifting…

Four retroactive inhibition (RI) experiments involving the AB, AC (same stimuli, different responses) paradigm were conducted to determine whether learning the original list (OL) and the interpolated list (IL) under different color-context conditions (different) would reduce RI relative to learning both lists under the same context conditions…

The following experiments are an attempt to clarify the role of learned safety by investigating the applicability of the concept of conditioned inhibition to a taste-aversion procedure and by differentiating its effects fromthose of latent inhibition. (Author)

The method of transfer learning was manipulated in a study of proactive inhibition. Results suggest that the joint recall of two lists during transfer increases list differentiation and reduces competition between alternative sets of responses on the retention test. (Editor/RK)

The present study attempted to increase the number of responses investigated in the study of retroactive inhibition. (Author/RK)

Investigates the possibility that memory for the conditioned response (CR) may be subject to the same sorts of interference that have been found to operate in verbal and perceptual-motor memory situations. Considers the implications for developing a general theory of memory. (Editor/RK)

It has been suggested that retrieval during a nonreinforced test induces reconsolidation instead of extinction of the mnemonic trace. Reconsolidation would preserve the original memory from the labilization induced by its nonreinforced recall through a hitherto uncharacterized mechanism requiring protein synthesis. Given the importance that such a…
