Peer reviewed Peer reviewed
Direct linkDirect link
Dodonov, Yury S.; Dodonova, Yulia A. – Intelligence, 2012
In the present study, speeded tasks with differing assumed difficulties of the trials are regarded as a special class of simple cognitive tasks. Exploratory latent growth modeling with data-driven shape of a growth curve and nonlinear structured latent curve modeling with predetermined monotonically increasing functions were used to analyze…

Modification of Impulsive and Reflective Cognitive Styles through Observation of Film-Mediated Models
Peer reviewed Peer reviewed
Ridberg, Eugene H.; And Others – Developmental Psychology, 1971
Cognitive style was modified in a sample of 50 impulsive and 50 reflective fourth-grade boys. Subjects viewed a film-mediated model displaying a response style opposite to their own cognitive style. The specific cues in the model's behavior which facilitated shifts in cognitive style varied with the intellectual levels of the subject. (Author/WY)

Nettelbeck, Ted; Wilson, Carlene – Intelligence, 2004
Inspection time (IT) and Peabody Picture Vocabulary Test (PPVT) scores from 75 school children aged 6-13 years in 2001 were compared with the performances of 70 children aged 6-13 years who had attended the same primary school in 1981 ["J. Exp. Child Psychol." 40 (1985) 1.]. ITs for the 2001 sample were measured with the same four-field…

Individual and Group Differences in Intelligence and Speed of Information Processing.
Vernon, Philip A.; Jensen, Arthur R. – 1983
In a study of the relationship between speed of information processing and general intelligence, vocational college students (50 black males and 56 white males) took eight different reaction time tests measuring the speed with which individuals perform various elementary cognitive processes, and a group test of scholastic aptitude (the Armed…

PDF on ERIC Download full text
Holzman, Thomas G.; And Others – 1980
The cognitive determinants of number analogy performance were studied by systematically manipulating the processing demands imposed by the items. To explore sources of developmental differences in analogical reasoning, subjects were included from two age levels, grades 4 and 5 and college. To allow the investigation of individual differences in…
