The present study evaluates the updating of long-term memory for duration. After learning a temporal discrimination associating one lever with a standard duration (4 sec) and another lever with both a shorter (1-sec) and a longer (16-sec) duration, rats underwent a single session for learning a new standard duration. The temporal generalization…

Often when failing to solve problems, individuals report some idea of the solution, but cannot explicitly access the idea. We investigated whether such intuition would relate to improvements in solving and to the manner in which a problem was solved after a 24- hour delay. On Day 1, participants attempted to solve Compound Remote Associate…

Associations between corresponding stimulus-response locations are often characterized as over learned, producing automatic activation. However, 84 practice trials with an incompatible mapping eliminate the benefit for spatial correspondence in a transfer Simon task, where stimulus location is irrelevant. The authors examined whether transfer…

Appetitive contextual excitation supported by intertrial unconditioned stimuli was more easily overcome by timed conditioned responding in rats using quiet (Experiment 1) rather than noisy (Experiment 2) food pellet deliveries. Head-entry responding in acquisition peaked above the contextual baseline when pellet delivery occurred 10, 30, 60, or 90…

Subjects learned one, two, or three verbal lists simultaneously. Recall of the common list after 24 hours increased directly as the number of lists learned simultaneously increased. Assuming that simultaneous learning reduced interference, the interference was from extraexperimental sources of a proactive nature. (Author/CP)

Illustrates the advantages of laboratory research into second language acquisition (SLA) by describing two studies of acquisition of second language syntax. The first, conducted in Wales, addresses the question of whether human morphological abilities can be understood in terms of associative processes, and the second presents a bootstrapping…
