Three studies involving 16 college students explored cognitive processes reflected by reaction time (RT) and movement time (MT). The hypothesis that correlations of RT and MT with measures of intelligence are due to effects on a common stage of information processing cannot be rejected on the basis of study findings. (SLD)

Six-month-old African-American infants' expectation of a visual stimulus was related to developmental measures. Reaction time was related to eye fixation in tests that measured visual recognition memory (VRM) and presented objects of different shapes to the infant. Reaction time and infants' stimulus expectation predicted VRM novelty preference.…

Experiments were conducted on the speed of encoding differences between 15 school-age individuals with and 15 individuals without mental retardation, while retaining a full memory load or half memory load. Subjects with mental retardation allocated fewer attentional resources to encoding, even though encoding may require more of their resources…

Fourth graders were presented decision-making tasks that required hands-on manipulation of objects or manipulation of images using a microcomputer. Computer manipulations used (1) keyboard input; (2) keyboard input and the presentation of reference objects; or (3) light pen input. Subjects required more time to respond to the task when using…

Suggests that the study of microdevelopment offers a potentially powerful way to relate learning and development where similar changes occur but in differing time frames. Microdevelopment analyzes short-term changes as developmental functions. Individuals and groups function at widely different developmental levels and grow in diverse nonlinear…

Nonuniversal theory can be used to reframe the learning-development dichotomy into a spectrum of important changes, ranging from small-scale learning events to large-scale developmental shifts. Using the universal-to-unique continuum as an organizing framework, several change mechanisms can be identified as necessary for movement through…

According to recent research studies, watching television has become the number one leisure activity among both children and adults. The effect of excessive television viewing on the cognitive development of children is reported. Solutions and suggestions for parents and teachers to help children integrate television into their lives in the most…

Trained 1- to 3-year-olds to touch a video screen displaying a unique target and appearing among varying numbers of distracters; correct responses triggered a sound and four animated objects on the screen. Found that children's reaction time patterns resembled those from adults in corresponding search tasks, suggesting that basic perceptual…

This article compares two theories on why children with language impairment have slower response times when completing linguistic and nonlinguistic tasks. First, the slowing is due to difficulty with a particular cognitive processes and second, the slowing is due to a general cognitive processing limitation. Clinical implications are discussed.…

Examined word recognition in early fluent Spanish-English bilinguals using a single word presentation lexical decision task. Reaction times (RT) and event-related brain potentials were measured while subjects made a lexical decision on words and pseudowords in either Spanish or English. Result show associative priming as measured by RTs but both…

Measurement of eye movements is a powerful tool for investigating perceptual and cognitive function in both infants and adults. Straightforwardly, eye movements provide a multifaceted measure of performance. For example, the location of fixations, their duration, time of occurrence, and accuracy all are potentially revealing and often allow…

This research was aimed at contributing to the current understanding of the underlying factors of naming speed and the causes of naming speed deficits. Forty regular readers and 40 dyslexic university students participated in the study. Electrophysiological (Event-Related Potentials [ERPs]) and behavioral measures were employed. Behavioral…

Research suggests screen reading is slower and possibly less accurate than reading from paper. Six study and test sessions over 10 months examined correct scores and retrieval responses for learning material presented via these two media. Correct scores did not differ suggesting that close matching of material can eliminate any decrement in…

Less is known about the effects of normal aging on speech output than other motor actions, because studies of communication integrity have focused on voice production and linguistic parameters rather than speech production characteristics. Studies investigating speech production in older adults have reported increased syllable duration (Slawinski,…

According to construal level theory (N. Liberman, Y. Trope, & E. Stephan, in press; Y. Trope & N. Liberman, 2003), people use a more abstract, high construal level when judging, perceiving, and predicting more psychologically distal targets, and they judge more abstract targets as being more psychologically distal. The present research…
