Unitary or Non-Unitary Nature of Working Memory? Evidence from Its Relation to General Fluid and Crystallized Intelligence
Peer reviewed Peer reviewed
Direct linkDirect link
Dang, Cai-Ping; Braeken, Johan; Ferrer, Emilio; Liu, Chang – Intelligence, 2012
This study explored the controversy surrounding working memory: whether it is a unitary system providing general purpose resources or a more differentiated system with domain-specific sub-components. A total of 348 participants completed a set of 6 working memory tasks that systematically varied in storage target contents and type of information…

The Strength and Generality of Stimulus Over-Selectivity in Simultaneous Discrimination Procedures
Peer reviewed Peer reviewed
Direct linkDirect link
Reynolds, Gemma; Reed, Phil – Learning and Motivation, 2011
Stimulus over-selectivity refers to behavior being controlled by one element of the environment at the expense of other equally salient aspects of the environment. This is a common problem for many individuals, including those with autism spectrum disorders, and learning difficulties, and presents a considerable problem for information processing…

The Influence of Temporal Resolution Power and Working Memory Capacity on Psychometric Intelligence
Peer reviewed Peer reviewed
Direct linkDirect link
Troche, Stefan J.; Rammsayer, Thomas H. – Intelligence, 2009
According to the temporal resolution power (TRP) hypothesis, higher TRP as reflected by better performance on psychophysical timing tasks accounts for faster speed of information processing and increased efficiency of information processing leading to better performance on tests of psychometric intelligence. An alternative explanation of…

Culture-Fair Cognitive Ability Assessment: Information Processing and Psychophysiological Approaches
Peer reviewed Peer reviewed
Direct linkDirect link
Verney, Steven P.; Granholm, Eric; Marshall, Sandra P.; Malcarne, Vanessa L.; Saccuzzo, Dennis P. – Assessment, 2005
Valid assessment with diverse populations requires tools that are not influenced by cultural elements. This study investigated the relationships between culture, information processing efficiency, and general cognitive capacities in samples of Caucasian and Mexican American college students. Consistent with the neural efficiency hypothesis,…

Listening Comprehension as a Function of Cognitive Complexity: A Research Note.
Peer reviewed Peer reviewed
Beatty, Michael J.; Payne, Steven K. – Communication Monographs, 1984
Tested, in two separate studies, the assumption that listening comprehension is dependent, in part, upon an individual's level of cognitive complexity. Found that high-complex individuals comprehend more listening material than do their cognitively simpler counterparts. Lends support to an information processing conceptualization of listening. (PD)

Measuring the Information Content of Written Materials in Mathematics.
Battista, Michael – 1978
The purpose of the study was to develop and validate a new method for measuring the subjective information of written materials in mathematics. In order to support the theoretical validity of the new measure, the study provided a derivation of the measure from Shannon's original information formula. Then the measure was used to measure the…
