Aim: The objective of this study was to investigate which attentional components are of predictive utility in differentiating children with attention-deficit-hyperactivity disorder, combined type (ADHD-C) from their peers without ADHD. Methods: Thirty-four children participated in the study: 17 males with ADHD-C (mean age 10y 4mo, SD 1y 9mo) and…

Backward inhibition (BI) refers to a reaction time cost incurred when returning to a recently abandoned task compared to returning to a task not recently performed. The effect has been proposed to reflect an inhibitory mechanism that aids transition from one task to another. The question arises as to precisely what aspects of a task may be…

An information-processing analysis of intelligence proposed by Eysenck and Furneaux was examined in an experimental study of semantic categorization and free recall by 11-year-old children of varying intelligence. Results, and implications of the results, are discussed. (Author/KC)

This study examines how rapid automatized naming (RAN) components-articulation time and pause time-develop from kindergarten to the end of first grade and how RAN components are related to different reading measures and to RAN total time. Sixty-two children were administered RAN tasks in kindergarten and at the beginning and end of Grade 1.…

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…

An information-processing framework is presented for understanding intelligence. Two levels of processing are discussed: the steps involved in solving a complex intellectual task, and higher-order processes used to decide how to solve the problem. (MH)

A six-process theory of analogical reasoning was tested by administering verbal analogy items to students in grades 3 through college. The items were classified according to five verbal relations: synonyms, antonyms, functional, linear ordering, and class membership. A new method of componential analysis that does not require precueing was used to…

This study demonstrated an aptitude-strategy interaction in linear syllogistic reasoning; specifically, that the efficiency of each of four alternative strategies for solving linear syllogisms would depend on subjects' verbal and spatial abilities. The four strategies, as well as research methods in aptitude-treatment interaction, are discussed.…
