Discusses Needham's findings by asserting that they extend understanding of infant perception by showing that the memory representations infants draw upon have bound together information about shape, color, and pattern. Considers the distinction between two senses of "recognition" and asks in which sense object recognition contributes to object…

Three studies explored 2- to 4-year-olds' ability to categorize objects based on novel underlying causal power. Children saw that a "blicket" would set off a machine and participated in categorization, induction, and association tasks. Results demonstrated that even 2-year-olds easily learn about an object's new causal power and…

Child-directed speech segments produced by mothers of 2- to 6-month olds varying in self-reported depressive symptoms were assessed on a summation test with 4-month olds of nondepressed mothers. Significant positive summation was obtained in infants tested with speech produced by mothers with comparatively fewer self-reported depressive symptoms…

The authors tested source memory across three conditions, one in which 3 strongly associated primes of a target word were presented in the same source as the target, one in which primes were presented in a different source than the target, and one in which no associates of targets were encoded. In the first 2 experiments, target source memory…

A lesson focusing on the names of muscles but relating them to more common words is presented, as current research suggests that the best way to teach vocabulary is to group related words. Students create visual representations of word groups and teach the words to the class.

Several theories of event-based prospective memory were evaluated in 3 experiments. The results depended on the association between the target event and the intended action. For associated target-action pairs (a) preexposure of nontargets did not reduce prospective memory, (b) divided attention did not reduce prospective memory, (c) prospective…

Despite earlier evidence that the presence of 2 redundant cues can facilitate activation of a common response, T. C. Rickard and D. Bajic (2004) found no dual-cue facilitation in the case of cued recall, provided that each cue-response association was learned independently. In this study the authors investigated the generality of their results…

Cholinergic systems are critical to the neural mechanisms mediating learning. Reduced nicotinic cholinergic receptor (nAChR) binding is a hallmark of normal aging. These reductions are markedly more severe in some dementias, such as Alzheimer's disease. Pharmacological central nervous system therapies are a means to ameliorate the cognitive…

This article reviews evidence and theories concerning the nature of stimulus representations in Pavlovian conditioning. It focuses on the elemental approach developed in stimulus sampling theory (R. C. Atkinson & W. K. Estes, 1963; R. R. Bush & F. Mosteller, 1951b) and extended by I. P. L. McLaren and N. J. Mackintosh (2000, 2002) and contrasts…

Author and book title recognition tests have been used extensively in reading-related research with both children and adults. The present paper reports the development of a book title and author recognition test and data from a UK sample of adults. Higher scores were obtained on the Author test than on the Title test. It is suggested that the…

Successful reading instruction entails not only acquiring new words but also remembering them after training has finished and accessing their word-specific representations when they are encountered in new text. We report two studies demonstrating that acquisition, retention, and transfer of unfamiliar words were affected differentially by isolated…

Great controversy exists on whether associative learning occurs without awareness. In Experiment 1, 31 participants received discrimination training by repeated presentations of two stimulus sequences (S1[subscript A] right arrow S2[subscript A], and S1[subscript B] right arrow S2[subscript B]), S1 being a masked stimulus. S2 were imperative…

Discussed the expansion of perceptual learning and the thought processes that relate our ideas. (RK)

This paper evaluates associative theories of sentence memory, based on the model of J.R. Anderson and G.H. Bower. A model of Human Associative Memory (HAM) is generalized and defined, and alternative models incorporating configural information are presented. (CK)
