Whereas neuroimaging studies of healthy subjects have demonstrated an association between the anterior cingulate cortex (ACC) and cognitive control functions, including response monitoring and error detection, lesion studies are sparse and have produced mixed results. Due to largely normal behavioral test results in two patients with medial…

External noise methods and observer models have been widely used to characterize the intrinsic perceptual limitations of human observers and changes of the perceptual limitations associated with cognitive, developmental, and disease processes by highlighting the variance of internal representations. The authors conducted a comprehensive review of…

Great controversy exists on whether associative learning occurs without awareness. In Experiment 1, 31 participants received discrimination training by repeated presentations of two stimulus sequences (S1[subscript A] right arrow S2[subscript A], and S1[subscript B] right arrow S2[subscript B]), S1 being a masked stimulus. S2 were imperative…

Witkin's concepts of field dependence-independence and restructing are discussed with reference to studies in Russia and in the Netherlands. These concepts are related to differences in style of perception and to success on both cognitive tasks and social tasks. It is suggested that restructing abilities may be trained and restructing ability may…

Investigated age changes and differences in personality as measured by the Holtzman Inkblot Technique (HIT). Concluded that the HIT measures perceptual-cognitive variables that are moderately stable in adulthood. (Author/ABB)

One hundred and forty-three subjects were identified as Field Independent or Field Dependent based on their performance on the Group Embedded Figures Test (GEFT), a measure of cognitive style. Results indicated that Field Independent students performed significantly better on course tests and had higher academic potential, as measured by the ACT,…

Resolution of cognitive dissonance following a pleasant and unpleasant task was examined under conditions of high and low justification with 60 male psychology students. Numbers were written at random and other tasks were completed followed by description of task to another subject. Mode of dissonance resolution was found to be a function of…

FIVE EXPERIMENTS WERE RUN AS A SERIES OF INITIAL EXPLORATIONS TO DETERMINE A WORKABLE, RESEARCH DEFINITION OF THE TERM "UNDERSTANDING" AND TO EVALUATE EXPERIMENTALLY ITS RELATIONSHIP TO DRILL, OR ROTE LEARNING. THE FIVE EXPERIMENTS DEALT WITH THE EFFECTS OF A VISUALLY IMPOSED COGNITIVE STRUCTURE UPON ROTE LEARNING, THE EFFECTS UPON ROTE LEARNING…

THE INSTITUTE'S TEST BATTERY IS INTENDED TO ASSESS THE CHILD'S ACHIEVEMENT IN COGNITIVE STYLE, PERCEPTUAL ABILITY, LANGUAGE DEVELOPMENT, AND READING ACHIEVEMENT. THE TWO MAJOR PHASES IN THE INSTITUTE'S RESEARCH PROGRAM ARE EXPLORATION OF EARLY ENVIRONMENTAL FACTORS AND THE DEVELOPMENT OF SCHOOL REMEDIAL, READING, AND ENRICHMENT PROGRAMS. THE INDEX…

TWO METHODS OF RESPONSE DESCRIBED BY PIAGET AND INHELDER FOR DRAWING APPROPRIATE BOUNDARIES AND SELECTING APPROPRIATE PREDRAWN BOUNDARIES FOR HYPOTHETICALLY CUT, SOLID GEOMETRIC FIGURES WERE INVESTIGATED TO SEE WHETHER SECONDARY SCHOOL STUDENTS COULD RESPOND IN APPROPRIATELY TO THE MATHEMATICAL TASKS. THE RESPONSES OF 8TH-, 10TH-, AND 12TH-GRADE…

This paper presents a study of eidetic imagery in children. An eidetic image refers to an afterimage which is both more vivid and longer lasting than other afterimages. The study attempts to analyze eidetic imagery as a psychometric problem and to relate it to other conceptually similar cognitive abilities. Two hundred forty-two second and third…

Many tests which attempt to produce intelligence quotient or mental age scores for children rely on time taken to complete the task for a valid result to be obtained. A number of tests were carried out with both Down's Syndrome and normal children (128 Down's Syndrome; 162 normal) in order to determine (1) relative abilities to complete the tasks…

This study examines the effects of sex, socioeconomic status, birth order and birth spacing on the cognitive performance of 12-week-old infants. A brief review of research on neonatal cognitive ability is followed by a description of the study itself. The subjects, 189 three-month-old Caucasian infants (61 first borns, 58 second borns, and 49…

The purpose of this study was to adapt the Hidden Figures Test (a measure of field dependence/independence) to microcomputer display and to assess its alternate form reliability when compared to a paper and pencil test. Participants included 58 undergraduate and graduate students (91.4% female) at a southeastern university who were fairly normal…
