Memory performance in linear order reasoning tasks (A > B, B > C, C > D, etc.) shows quicker, and more accurate responses to queries on wider (AD) than narrower (AB) pairs on a hypothetical linear mental model (A -- B -- C -- D). While indicative of an analogue representation, research so far did not provide positive evidence for spatial…

Examined the hypothesis that aging and hemispheric laterality interact to produce relatively greater decrements in older individuals in right hemispheric dominant (visuospatial) than left hemispheric dominant (verbal) tasks in 24 early middle-aged and 24 older males. Data did not support the notion of a laterality effect associated with aging.…

Three studies examined how children of different ages and cultural backgrounds represent depth relations of near and far, and front and behind, on a two-dimensional surface. A lateral bias to place near objects on the left side appeared in English and Hebrew readers of all ages and in older Arabic readers. (MM)

Retinoid signaling has been recently shown to be required for mnemonic functions in rodents. To dissect the behavioral and molecular mechanisms involved in this requirement, we have analyzed the spatial and recognition working memory in mice carrying null mutations of retinoid receptors RAR[subscript [beta]] and RXR[subscript [gamma]]. Double…
