Two studies were performed to determine the relationship between cellular phone use and either reaction time or performance among college students. In the first study 60 undergraduates completed a computerized reaction time test. Mean reaction times were significantly higher when participants were talking on a cellular phone, either handheld or on…

Online comprehension of naturally spoken and perceptually degraded words was assessed in 95 children ages 12 to 31 months. The time course of word recognition was measured by monitoring eye movements as children looked at pictures while listening to familiar target words presented in unaltered, time-compressed, and low-pass-filtered forms. Success…

Previous research has shown that synchronized flicker can facilitate detection of a single Kanizsa square. The present study investigated the role of temporally structured priming in discrimination tasks involving perceptual relations between multiple Kanizsa-type figures. Results indicate that visual information presented as temporally structured…

A study was conducted that attempted to show changes in electroencephalographic (EEG) patterns (identified using topographic EEG mapping) when children were required to perform the relatively simple task of button pressing during an eyes-open baseline session of low cognitive demand and a complex reaction time (RT) task of high cognitive demand.…

Studies of the pauses between teachers' questions and students' responses have indicated that lengthening wait-time produces significant improvement in intellectual performance. Two types of pauses have been identified: the pause after teachers pose questions and students respond, and the pause that takes place when students hesitate momentarily…

Cognitive processes, particularly in regard to negative content schemata, seem to play an instrumental role in the development and maintenance of depression. In order to better understand the nature of negative schemata in depressed individuals, both depressed and nondepressed subjects participated in two studies in which they were required to…

Recent studies of self-referent cognition have demonstrated that people process information about themselves more efficiently than other kinds of information. To investigate latency effects in self-referent decision-making, 60 college students participated in a three phase study. In phase one, each subject chose the trait within a pair that best…

This study of teacher education graduate follow-up surveys examined the relationship between response rate and number of graduates, questionnaire length, and follow-up contacts. Also, the study investigated survey practices differentiating between surveys which had high and low return rates in such areas as number of follow-up contacts,…

Timing and speed are suggested to be the two general factors of coordination that differentiate people across a variety of motor movements. This study provides evidence for a third general factor of coordination, that of force control. Subjects that exhibit low variability in reproducing a target force with one effector, such as the finger, show…

Previous studies indicate increasing, significant univariate and multivariate correlation between reaction time (RT) tasks and intelligence. Using multiple regression analyses, data from an earlier study by Brown and Boretz were reanalyzed to further investigate the relationship between the speed at which an individual is able to process stimuli…

A study was conducted to determine if attentional difficulties would be found in reading disabled children and to discover if increasing the complexity of a task would result in a relative decrease in the performance of the children. Twelve dyslexic boys, aged eight and nine, and 12 normal subjects similar in age and IQ participated in the study.…

Instructional strategies for successfully teaching concepts are found throughout the instructional design literature. These strategies primarily consist of presenting learners with definitions, examples, and non-examples. While examples are important presentation instruments, theorist suggests that examples should not be re-used in the assessment…

This paper reports two studies which examined the relationship between problem solving strategies, response latencies, and efficient performance on measures of conceptual tempo. Study I demonstrated that teaching 8-year-old children to use efficient strategies on problem-solving tasks increased both the quality of their performance and their…

A component skills model of reading is presented. On the basis of the model, five component factors are hypothesized: grapheme encoding, encoding multiletter units, phonemic translation, automaticity of articulation, and depth of processing in word recognition. The fit of the hypothesized component factor model is tested using covariance data for…

The effects of the availability of behaviorally stated objectives on the learning process were studied. It was hypothesized that objectives would serve as orienting stimuli which would help students to attend to, process, and organize relevant aspects of displayed information in accordance with stated objectives. Therefore, the presentation of…
