Three experiments examined whether the perception and retention of feature relations, thought to be critical for object recognition in adults, are evident in early infancy. Three month olds' 24-hour retention was disrupted when features of a 6-item mobile were recombined, indicating that they not only encode feature relations but also remember…

Three experiments explored the effect of introducing novel information about a central target after a short delay on six-month-old's recognition of the original target, the novel exposure target, and a completely novel one. They found that the infants' memory of a central target is resistant to impairment by conflicting postevent information after…

To gather normative observations on a visual memory test developed by A. Rey (1964), it was administered to 100 temporal-lobe epilepsy patients with memory deficits and 56 outpatients with neurological disorders. Results suggest a cutoff score of 7 on the memory test may alert the clinician to possible factitious memory complaints. (SLD)

Six experiments involving a total of 112 college students demonstrate that a robust memory for visual context exists to guide spatial attention. Results show how implicit learning and memory of visual context can guide spatial attention toward task-relevant aspects of a scene. (SLD)

Adults' source judgments are more accurate when they focus on speakers' emotions than when adults focus on their own emotions. Focusing on speakers may lead to better source memory because it encourages processing of the perceptual characteristics of the source and binding of that information to the content of what is being said. The purpose of…

Does repetition blindness represent a failure of perception or of memory? In Experiment 1, participants viewed rapid serial visual presentation (RSVP) sentences. When critical words (C1 and C2) were orthographically similar, C2 was frequently omitted from serial report; however, repetition priming for C2 on a postsentence lexical decision task was…

This paper studies the dynamics of attempting to access two spatial memories simultaneously and its implications for the accuracy of recall. Experiment 1 demonstrates in a range of conditions that two cues pointing to different experiences of the same object location produce little or no higher recall than that observed with a single cue.…

Background: Very little is known about the neuropsychological correlates of adaptive functioning in people with intellectual disabilities (ID). This study examined whether specific cognitive deficits and demographic variables predicted everyday functioning in adults with ID. Method: People with ID (n = 101; ages 19-41 years; mean education = 11…

Few studies have specifically investigated the cognitive correlates of employment for persons with mental retardation. To evaluate the relationship of cognitive and adaptive functioning to work status, 56 competitively employed and 55 unemployed individuals with mental retardation underwent a comprehensive neuropsychological and adaptive…

Empirical data suggest that there is at most a very small sex difference in general mental ability, but men clearly perform better on visuospatial tasks while women clearly perform better on tests of verbal usage and perceptual speed. In this study, we integrated these overall findings with predictions based on the Verbal-Perceptual-Rotation (VPR)…

The purpose of this study was to determine the extent to which verbal processes influence recognition memory for visual scenes in preschool children. Children were shown line drawings of 12 pairs of items and were asked to describe them. One week later, a recognition test was given in which ability to remember elaborated and unelaborated pictures…

Compared was the visual memory of 18 deaf and 18 normal hearing children (7- to 12-years-old). Ss' visual discrimination and visual memory were tested with filmstrip materials from Project LIFE (Language Improvement to Facilitate Education). Time scores and error scores were used to measure the performances of both groups. Results showing that…

In a series of six experiments, undergraduate college students visually imagined letters or words and then classified as rapidly as possible the imagined letters for some physical property such as vertical height. This procedure allowed for a preliminary assessment of the temporal parameters of visual imagination. The results delineate a number of…

This paper discusses some methodological, theoretical and physiological issues to be considered in the use of film tests in research relating to visual cognition and memory. One trouble spot in methodology is the use of a square data matrix with an insufficient number of observations in proportion to variables. A second methodological problem…

Human visual recognition on the basis of shape but regardless of size was investigated by reaction time methods. Results suggested two processes of size scaling: mental-image transformation and perceptual-scale transformation. Image transformation accounted for matching performance based on visual short-term memory, whereas scale transformation…
