The less-complex central nervous system of many invertebrates make them attractive for not
only the molecular analysis of the associative learning and memory, but also in determining …

Most long-term memories are formed as a consequence of multiple experiences. The
temporal spacing of these experiences is of considerable importance: experiences …

Contemporary explanations of the trial-spacing effect (TSE) were evaluated. Experiment 1
revealed, in rats given tone–footshock trials with 15-, 60-, or 900-s intertrial intervals (ITIs), a …

In three experiments with rat subjects, we examined the effects of trial spacing in appetitive
conditioning. Previous research in this preparation suggests that self-generated priming of …

Two groups of cuttlefish (Sepia officinalis) were used to demonstrate classical conditioning
in this species and to determine whether the resulting approach response would be that of …

Hermissenda crassicornis is a model for studying the molecular and cellular basis for
classical conditioning, based on its ability to associate light with vestibular stimulation. We …

Classical conditioning of the mollusc, Hermissenda crassicornis, is a model system used to
study cellular correlates of associative learning. Paired presentation of light and turbulence …

An opaque screen moving overhead elicits an escape response in the crab Chasmagnathus
that after a few presentations habituates for a long period (long-term habituation). Two types …

underlying sensitization and associative learning 2. 3. Induction of presynaptic facilitation …

Extinction of classical conditioning is thought to produce new learning that masks or
interferes with the original memory. However, research in the nudibranch Hermissenda …
