Ss' reaction time was measured from onset of a light stimulus until activiation of a microswitch by three types of buttons. Reaction times were significantly faster with the depressed panel mounted and hand-held buttons than with the released panel mounted button. (Author/DLS)

The study investigated word-finding skills in 30 learning disabled (LD) boys (ages 8-to-11-years). Ss were administered measures designed to explore word-finding ability in three stimulus contexts for high- and low-frequency words.

In the investigation described here, the relationship between individual differences of intelligence, as measured by the Wechsler Adult Intelligence Scale (WAIS; Wechsler, 1958), and inspection time has been examined. (Author)

A dual-task paradigm was used to assess attentional processing demands during visual word recognition. By manipulating the difficulty of each task, it is argued that the procedure estimates the attention demands of the memory-access component of word recognition. (Editor)

Used nonverbal serial reaction time paradigm to evaluate 7- to 11-year-olds' motor sequence learning in relation to reading, cognitive ability level, and attention problems. Found that children demonstrated the response profile associated with motor sequence learning, but the profile component indicating implicit sequence learning was not reliably…

Through an experiment with 30 college students, a theory was developed to describe response times and ratings of the difference of stimuli. The model was applied in ratings of the likableness of persons by 22 other college students. A theory of comparative response times and difference judgments is discussed. (SLD)

P. Lewicki and others (1988) suggested that subjects unconsciously abstract tacit knowledge about a complex pattern of events in a situation that departs from the artificial grammar learning pattern. The present experiment with 40 third year university students offers an alternative framework that does not assume unconscious rule abstraction. (SLD)

Visual and auditory coding processes in learning-disabled students (SLDs, n=19) and control students (SCs, n=19) were examined. Analysis of decision latencies revealed that with initial task exposure, SLDs responded more slowly than SCs, but confusability patterns were similar. With practice, overall latencies became comparable, while…

Four multiply handicapped students (aged 5-11) received skill instruction under four experimental conditions, involving differing teacher wait-times and intertrial interval durations. Student performance was superior under the long wait-time conditions irrespective of the length of the intertrial interval. (Author/JDD)

A new theoretical analysis of the stop-signal model is proposed. Within the concepts of crude- and net-hazard functions, the nonobservable control-latency distribution can be estimated from observable reaction times. This result allows a test of the Logan and Cowan model (1984) without simplifying assumptions. (SLD)

The development of visual orienting to a cued target on the part of practicing and nonpracticing tennis players aged 13, 16, and 25 years was examined. Results indicated that practicers were not faster than nonpracticers in processing visual information and that subjects of all ages oriented attention voluntarily to cued locations. (LB)

This study of the automatic word and sign recognition of 66 hearing and deaf adults found that responding in sign took longer and created more Stroop interference than responding orally, independent of hearing status. Deaf subjects showed greater automaticity in recognizing signs than words, whereas hearing subjects showed greater automaticity in…

Explains the use of pigeons in behavioral psychology research for modeling human behavior and discusses instructional objectives for humans. Topics addressed include the relationship between response rate and reinforcer rate; resistance to alternative reinforcement; choice and matching; and persistence and reinforcement. (Contains 11 references.)…

Naming speed skills of 45 dyslexic children (mean ages=8, 13, and 17) and slow learning children (mean age=10) were compared with those of normally achieving children. Results indicated that children with dyslexia and slow learners have persistent and severe problems in naming speed for all stimuli, regardless of whether the stimulus requires…
