A meta-analysis of research on the relationship between inspection time (IT) and IQ was performed. The analysis was designed to determine whether a non-zero relationship between IT and IQ exists, estimate the size of this relationship, and test whether IT is ontogenetically related to "g" (intelligence).

Three experiments used the differential frequency effect as a diagnostic tool to investigate the mental representation of disyllabic compound words in Mandarin Chinese. The results indicated that, when both word frequency and morpheme frequency were held constant, high-frequency first syllables slowed responses to real words. (41 references) (MDM)

Describes a study that investigated the effects of flowcharts utilizing maplike symbols on performer efficiency in completing a complex procedural task. The effectiveness of instructional flowcharts is discussed; map learning is examined; and data on response times for three presentation formats (i.e., map, flowchart, and list) and four levels of…

Three studies explored age changes and individual differences in preschoolers' sustained attention in different contexts. Found that changes occurred earlier for play and television viewing than for reaction time tasks. Results suggest that children have stable tendencies to sustain attention but that attention varies with task demands and…

Presents guidelines developed by the ICOLC (International Coalition of Library Consortia) regarding vendor contracts and negotiations that involve electronic information resources. Highlights include content issues, including HTML, use of printers, and use of multimedia; and platform issues, including system architecture, access control, security…

Reviews the chronometric research conducted by Arthur Jensen and what it has done to support the idea of a correlation between various composite reaction-time variables and IQ tests. Discusses the importance of Jensen's work in the exploration of general intelligence. (SLD)

Investigates two problems: (1) do learning effects accrue in accuracy or response time when computerized tests are administered in two sessions? and (2) what are the effects of tonal pattern order and contour types on average item difficulty and length of response time for children with different levels of achievement? (DSK)

Describes the construction of a timer to determine reaction time for use in life science classes. Uses a computer program with a menu that suggests specific experiments. (DDR)

Social identity theory holds that social group memberships become part of the psychological self, affecting thoughts, feelings, and behavior. However, tests of this hypothesis have mainly involved judgmental dependent measures. A method is suggested that can provide more direct evidence. Discusses use of that method. (KW)

Two experiments tracked infants' eye movements to examine use of word-initial information to understand fluent speech. Results indicated that 21- and 18-month-olds recognized partial words as quickly and reliably as whole words. Infants' productive vocabulary and reaction time were related to word recognition accuracy. Results show that…

Rats obtained food-pellet reinforcers by nose poking a lighted key. Experiment 1 examined resistance to extinction following single-schedule training with different variable-interval schedules, ranging from a mean interval of 16 min to 0.25 min. That is, for each schedule, the rats received 20 consecutive daily baseline sessions and then a session…

Five adult humans were tested for emergent conditional discriminations under rapid-responding contingencies. During four-comparison matching-to-sample baseline training (AB and AC), limited-hold contingencies for responding to samples and comparisons were gradually restricted to the shortest duration consistent with at least 95% accuracy and no…

Most authorities consider balance to be a component of skill-related physical fitness. Balance, however, is directly related to health, especially for older adults. Falls are a leading cause of injury and death among the elderly. Improved balance can help reduce falls and contribute to older people remaining physically active. Balance is a…

The purpose of the present study was to determine whether playing a specific ball sport, such as tennis, could maintain the coincidence-timing (CT) performance of older adults at a similar level to that of younger ones. To address this question, tennis players and nonplayers of three different age ranges (ages 20-30, 60-70, and 70-80 years)…

One theoretical framework which addresses students' conceptions and reasoning processes in mathematics and science education is the intuitive rules theory. According to this theory, students' reasoning is affected by intuitive rules when they solve a wide variety of conceptually non-related mathematical and scientific tasks that share some common…
