Although intelligence has traditionally been identified as "the ability to learn" (Peterson, 1925), this relationship has been questioned in simple operant learning tasks (Spielberger, 1962). Nevertheless, recent pieces of research have demonstrated a strong and significant correlation between associative learning measures and intelligence…

This study found correlations (.45 to .59) between scores on a battery of auditory discrimination tasks and measures of intelligence and academic aptitude in two samples of college students. An implication is that intelligence is a potential confounding variable in studies of the auditory perceptual abilities of various clinical populations.…

The first part of this paper briefly describes two studies concerned with cognitive processes in children. One study examined the ability of Kindergarten and First Grade children to apply a simple rule of logical inference in order to solve a two-object discrimination problem. Specifically, the rule was of the form "if A, then not B." A second…

To test the theory that retardates are particularly slow in forming some visual habits, especially attention, a series of experiments were performed using a laboratory device which forced subjects to discriminate between color and form in exchange for an incentive reward. Stochastic models were applied to tests of lower level retardates which…

Compared were performances of 12 educable mentally retarded (EMR) and 12 normal children in grade 6 on a perceptual learning task to determine whether individuals with different intelligence levels have different learning abilities. A protable minicomputer was used to present "old letters" (usual lower case letters) and "new letters" (letter-like…

Discrimination learning, memory, and transfer capacity were assessed in 56 institutionalized moderately to severely retarded adults to provide information on trainability. Generally, the higher functioning Ss, defined by IQ and adaptive behavior learned more rapidly than did the lower functioning Ss. (Author/SW)

Three papers--comments, a reply to comments, and a rejoinder--discussing a conclusion about the nature of general intelligence based on the size loadings of a psychomotor test of discrimination reaction time are presented. The use of Spearman's "g" is the center of the controversy. (TJH)

Ten young males (aged 16-to-22 years) whose IQ scores ranged from 51 to 77 were compared on a simple discrimination task with ten male university students (aged 18-to-23 years) and 28 nonretarded male children (aged 7-to-11 years) in order to determine if reaction time is a consequence of mental retardation.
