Paper sets out an attempt to use the changes in implicit associative responses resulting from semantic constraints to examine some features of the associative network aroused by the perception of a complete sentence. (Author)

Voltage-gated potassium channels (Kv) are critically involved in learning and memory processes. It is not known, however, whether the expression of the Kv1.1 subunit, constituting Kv1 channels, can be specifically regulated in brain areas important for learning and memory processing. Radioactive in situ hybridization was used to evaluate the…

Learning tasks are typically thought to be either hippocampal-dependent (impaired by hippocampal lesions) or hippocampal-independent (indifferent to hippocampal lesions). Here, we show that conditioned taste aversion (CTA) learning fits into neither of these categories. Rats were trained to avoid two taste stimuli, one novel and one familiar.…

The study was designed to developmentally assess the effect of relational imagery training, unitized pictorial relations, and the combination of both on the recall of noun triplets by 120 first, third and sixth graders. In the unitized picture condition, relations were imposed by the experimenter, whereas the relational imagery training condition…

Children in grades 1 and 4 and adults were given instruction to image or to verbalize a sentence in order to study a stimulus provided aurally. Both types of instruction enhanced memory, but results indicate the greater requirements for subject-generated mediation to some degree penalized younger subjects and benefited older ones. (GO)

Examines the latency of associative activation in memory by varying the stimulus onset asynchrony (SOA) between a prime word and a test word, thereby establishing the minimum SOA needed to produce a significant associative priming effect on lexical decision times. (Author/RK)

The extent to which an orienting activity exerts control over the encoding process was studied. Two experiments were reported in which associative meaningfulness was varied under conditions of semantic and nonsemantic processing. Both experiments showed effects of meaningfulness following both semantic and nonsemantic tasks. (Author/MH)

Tests the theory that culturally associated words in a pair and nonassociated words in a pair differ after a single study trial in terms of their frequency representation in memory. (Editor/RK)

Individual differences in retention, with an emphasis on their relationship with learning speed and other cognitive factors, were studied in 685 military recruits. In all of the forgetting conditions, the fastest learners remembered more and relearned faster. Results support the existence of individual differences in retention. (SLD)

Two experiments examined whether associating an imitation task with an operant task affected 6-month-olds' memory for either task. Results indicated that infants successfully imitated a puppet's action for up to 2 weeks only if the associated operant task (pressing a lever to activate a miniature train) was retrieved first. Follow-up study…
