Response Time Analysis in Cognitive Tasks with Increasing Difficulty
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…

Intelligence, but Not Emotional Intelligence, Predicts Iowa Gambling Task Performance
Peer reviewed Peer reviewed

Demaree, Heath A.; Burns, Kevin J.; DeDonno, Michael A. – Intelligence, 2010
The Iowa Gambling Task (IGT) is a famous and frequently-used neuropsychological task that is thought to reflect real-world decision-making. There has been some debate, however, about the degree to which the IGT involves cold (cognitive) versus hot (emotional) processing. The present study incorporated 68 healthy individuals and used measures of…

Inspection Time and the Relationship among Elementary Cognitive Tasks, General Intelligence, and Specific Cognitive Abilities.
Peer reviewed Peer reviewed
Petrill, Stephen A.; Luo, Dasen; Thompson, Lee Anne; Detterman, Douglas K. – Intelligence, 2001
Studied the extent to which inspection time (IT) relates to psychometric intelligence through general intelligence or through group factors and examined whether IT relates to psychometric intelligence independent from other elementary cognitive tasks. Results for 569 twins aged 6 to 13 years suggest that IT and other elementary tasks predict…

The Prediction, from Infancy, of Adult IQ and Achievement
Peer reviewed Peer reviewed
Direct linkDirect link
Fagan, Joseph F.; Holland, Cynthia R.; Wheeler, Karyn – Intelligence, 2007
Young adults, originally tested as infants for their ability to process information as measured by selective attention to novelty (an operational definition of visual recognition memory), were revisited. A current estimate of IQ was obtained as well as a measure of academic achievement. Information processing ability at 6-12 months was predictive…

When Will the Milk Spoil? Everyday Induction in Human Intelligence.
Peer reviewed Peer reviewed
Sternberg, Robert J.; Kalmar, David A. – Intelligence, 1998
The mental processes underlying everyday predictive and postdictive judgments about objects undergoing change or no change were studied with 40 adults. Results supported a single information processing model for describing performance on both prediction and postdiction problems. The implications of the study of everyday inductive reasoning are…

What Process Mediates Predictions of Childhood IQ from Infant Habituation and Recognition Memory? Speculations on the Roles of Inhibition and Rate of Information Processing.
Peer reviewed Peer reviewed
McCall, Robert B. – Intelligence, 1994
This editorial proposes that the dependent variables that predict childhood intelligence quotient (IQ) from habituation and recognition memory assessments made during infancy may primarily reflect individual differences in rate of information processing. Inhibition may be a stable thread in mental development. (Author/SLD)
