Suggests that the general ability structure for retardates is more complex than the structure for normals, containing a "stimulus trace" factor in addition to verbal-educational and spatial-perceptual parameters. (RL)

Discusses differential and information processing theories of intelligence and the problems of measuring intelligence. Considers the influence of sociocultural factors on the test performance of individuals and the procedures which have been suggested to reduce bias. (RJC)

This article discusses the nature of intelligence, introducing a new distinction between macrocomponents and microcomponents of human intelligence. Microcomponents are fairly elementary operations such as inference and application of analogical relations. Macrocomponents are the global-level constellations of processes that are formed from…

The potential of chemistry to improve one's learning capacity is discussed. (CK)

In an argument for orthogonal variables to explain intelligence, higher-order constructs, including "g" as a single thing in intelligence, are suggested to inevitably result from complex systems with interrelated parts. Biological reductionism and other arguments for the higher-order constructs as explanations of intellectual functioning…

Considers whether birds are intelligent creatures. Claims that birds act on stimuli affecting survival and that they have brain activity, both indications of intelligence. (HB)

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…

Administered marker tests for 5 of the constructs described in the Gf-Gc theory (fluid ability-crystallized ability) of cognitive abilities to 64 adults who also completed inspection time estimation. Results were consistent with the proposition that general intelligence depends exclusively or substantially on speed of processing. (SLD)

The present study evaluated cerebral lateralization during Raven's progressive matrices (RPM) paradigm in female and male subjects. Bilateral simultaneous transcranial Doppler (TCD) ultrasound was used to measure mean blood flow velocities (MBFV) in the right and left middle cerebral arteries (MCAs) in 24 (15 females and 9 males) right-handed…

Visual intelligence is a key element in the thought processes of the most capable and creative among individuals, and this intelligence is closely related to analogical thinking, a learner's ability to make connections between prior knowledge and newly presented information. This article describes an approach to teaching scientific inquiry at…

Developing personalised web-based learning systems has been an important research issue in e-learning because no fixed learning pathway will be appropriate for all learners. However, most current web-based learning platforms with personalised curriculum sequencing tend to emphasise the learner preferences and interests in relation to personalised…

This paper examines how Piaget, Werner, and Gardner differ regarding the roles of cognition, intelligence, and learning in the developmental process. Piaget believes in the predominance of genetic factors. Werner stresses the influence of biological factors, while Gardner proposes that the environment plays a greater influence in how intelligence…

The capacity to be in control of one's thoughts, emotions, and physiology can form an internal safety net preparing children to face the challenges and opportunities of life. This is the goal of the Inner Resilience Program in the New York City Schools. Teachers in the Inner Resilience Program's intervention are exposed to calming and focusing…

Studies that examine the effects of exercise on children's intelligence, cognition, or academic achievement were reviewed and results were discussed in light of (a) contemporary cognitive theory development directed toward exercise, (b) recent research demonstrating the salutary effects of exercise on adults' cognitive functioning, and (c) studies…

Causal reasoning represents one of the most basic and important cognitive processes that underpin all higher-order activities, such as conceptual understanding and problem solving. Hume called causality the "cement of the universe" [Hume (1739/2000). Causal reasoning is required for making predictions, drawing implications and…
