Two experiments were conducted to assess whether the distribution of fixation times might be related to the prevailing cognitive activity involved with two different tasks, i.e., driving and observing colored fields. The results suggest that the distribution of fixation times can be associated with the prevailing cognitive activity while viewing.…

A technique is introduced to study the flow of information through processing stages in choice reaction time tasks. It was designed to determine whether response preparation can begin before stimulus identification is complete ("continuous" models) or if a stimulus must be fully identified prior to any response activation…

Much effort has been invested in time-on-task research. Time-on-task is described as a proxy term for the notion of "attention," and the findings of time-on-task research are described as less relevant to the classroom teacher than information contained in methods texts. (JN)

Letter encoding is typically viewed as an automatic process that is both obligatory and interference free. In these experiments, either familiar or non-familiar primes produced significant amounts of interference even when subjects were trying to ignore the visual input. Early perceptual components of encoding are both obligatory and resource…

The article examines the reflective versus the impulsive cognitive styles and the implications of these styles for special education teachers. (PHR)

Investigates the differential effect of modeling procedures on slow and fast responders' performance on a haptic-visual matching test. Also studies the differential effect of modeling of impulsive v reflective modes of responding, and of model success v model failure. (Author/SS)

The effects of several factors on expended processing capacity were measured. Expended processing capacity was greater when information was retrieved from secondary memory than from primary memory, when processing was of a deep, semantic nature than when it was shallow and physical, and when processing was more elaborate. (Author/GDC)

Three problem-solving strategies--working backward from the unknown, forward from the given, and mixed--were applied to interrelated algebra equations. The mixed strategy was most popular and most efficient with grouped variables. Memory load or information-processing load differences among the strategies were evident. (CP)

Instruction designed to facilitate planning was provided to 12 math students (ages 9-12) with learning disabilities to determine if there would be differential effects on individual students. Teaching control and regulation of cognitive activity was beneficial for all students but was especially helpful for those with poor planning skills.…

This study explored differences among 10 children with Central Auditory Processing Disorder (CAPD), 10 age-matched peers, and 10 young adults, by examining vocal reaction time when presented with printed one- and two-syllable words. Children with CAPD produced significantly more errors than their peers or adults, specifically for long-delay…

This exploratory study investigated the influence of two recreational computer games on children's subsequent performance on computer-based instructional tasks. Examined speed, correct solutions, and cognitive processes; and suggests that the extent of recreational game influence depends on how closely the game type matches the design of the tasks…

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…
