Eight experiments tested priming in short-term memory as a model for latent inhibition and habituation. The model postulates that the two phenomena result from reduced processing when a representation of the target stimulus is already active (primed) in short-term memory at the time of its presentation. Priming is assumed to depend on the integrity of an association formed between the contextual stimuli and the conditional stimulus (CS) during exposure. Using a procedure that should have overshadowed the context, Experiment 1 found that latent inhibition and habituation were nevertheless maintained when a second CS of either equal or shorter duration overlapped with the target during exposure. Experiment 2 found no support for the priming of a configural stimulus when simultaneous compounds were preexposed. Experiment 3 ruled out sensitization and/or pseudoconditioning as an alternative explanation of latent inhibition. Experiments 4, 5 and 6 showed that sensory preconditioning as well as habituation and latent inhibition were obtained with compound exposure, providing evidence that the added CS was indeed processed along with the target. In Experiment 7, sequential pairings produced as much latent inhibition as compounds but less sensory preconditioning. Experiment 8 showed that retardation of conditioned inhibition was not attenuated by compound exposure. These results are interpreted as consistent with a correlational approach to classical conditioning.

Different versions of complex, simple, and running tests of immediate memory span were compared in their ability to predict fluid intelligence (gF). Conditions across memory tasks differed in terms of whether or not a secondary cognitive task was interleaved between to-be-remembered items (complex versus other span tasks), whether or not more items were presented than were ultimately to-be-remembered (running versus other span tasks), and whether presentation rate was relatively fast or slow (running and simple span tasks). Regressions indicated that up to 42.6% of variance in general fluid gF was explained by the memory span measures entered in different combinations. Across comparisons, shared relationships among span tasks accounted for a plurality of total variance in gF. Results indicate that in spite of procedural differences and resulting intra-individual variance in memory performance, the present memory tasks captured largely the same inter-individual variance in working memory capacity, insofar as this is important for higher-order cognition.
