Developmental epidemiologically based preventive trials: Baseline modeling of early target behaviors and depressive symptoms

Describes a conceptual framework for identifying and targeting developmental antecedents in early childhood that have been shown in previous work to predict delinquency and violent behavior, heavy drug use, depression, and other psychiatric symptoms and possibly disorders in late adolescence and into adulthood. Criteria are described that guided choices of targets for two epidemiologically based, randomized preventive trials carried out in 19 elementary schools in the eastern half of Baltimore, involving more than 2,400 first-grade children over the course of first and second grades. Baseline models derived from the first of two cohorts show the evolving patterns of concurrence among the target antecedents. The central role of concentration problems emerged. From Fall to Spring in first grade, concentration problems led to shy and aggressive behavior and poor achievement in both genders and to depressive symptoms among girls. There was evidence for reciprocal relationships in girls. For example, depressive symptoms led to poor achievement in both girls and boys, whereas poor achievement led to depressive symptoms in girls but not boys, at least over the first-grade year. These results provide important epidemiological data relevant to the developmental paths leading to the problem outcomes and suggest preventive trials.     

Generation of internally restricted random-dot patterns

The probability of a successful draw of a dot position within a random dot pattern is considered for the special case where a minimal city block distance is imposed separating any two dots within the random pattern. An analytical solution is derived and is tested against Monte Carlo simulations. The agreement is considered to be good, except at extremely low probabilities of a successful draw. An alternative method, based upon the utilization of successively coarser grids, is also given. Formulas are also provided for circular and for diamond-shaped separation regions.     

Pain perception in irritable bowel syndrome

Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder characterized by chronic abdominal discomfort or pain in the absence of detectable organic disease. IBS is common and is associated with a significant impairment in health-related quality of life. Enhanced perception of visceral stimuli ("visceral hypersensitivity") appears to be an important pathophysiological mechanism. Early IBS studies using functional brain imaging techniques suggest an alteration in central pain modulation circuits, rather than an increased sensitivity of peripheral visceral pain pathways. The frequent comorbidity with psychiatric disorders suggests the possibility of shared pathophysiological mechanisms and etiologic factors.     

When static media promote active learning: annotated illustrations versus narrated animations in multimedia instruction

In 4 experiments, students received a lesson consisting of computer-based animation and narration or a lesson consisting of paper-based static diagrams and text. The lessons used the same words and graphics in the paper-based and computer-based versions to explain the process of lightning formation (Experiment 1), how a toilet tank works (Experiment 2), how ocean waves work (Experiment 3), and how a car's braking system works (Experiment 4). On subsequent retention and transfer tests, the paper group performed significantly better than the computer group on 4 of 8 comparisons, and there was no significant difference on the rest. These results support the static media hypothesis, in which static illustrations with printed text reduce extraneous processing and promote germane processing as compared with narrated animations.     

The System-Topics Framework and the Structural Arrangement of Systems within and around Personality

ABSTRACT The field of personality psychology possesses rich theories and excellent research, but few good means to communicate them. The system-topics framework is an integratory approach that divides the study of personality into three central topics and their subdivisions: (a) the components of personality, (b) the organization of those components, and (c) the development of those components and their organization over time. The present article describes the system-topics framework and then examines the addition of a potential new topic useful to an improved exposition of the field: the structural arrangement of the component systems in and around personality. A three-dimensional model of these systems is created that can synthesize the many spatial metaphors used in earlier personality theory and research. The reasons for integrating this structural model within the system-topics framework and how such integration can be accomplished are discussed.     

Festinger's Theory of Cognitive Dissonance Applied to School Counseling

Aspects of Festinger's theory of cognitive dissonance were partially integrated with a Rogerian type of orientation to school counseling. Festinger's term “dissonance” was presented as complementary to Rogers' term “incongruence.” A number of counselor activities were derived from the two complementary orientations which, if employed, would seem to enhance the probability of a self-directed change occurring within the student. These included such activities as the school counselor attempting to: (a) provide an accepting non-threatening atmosphere; (b) assist students or counselees in developing sufficient dissonance; (c) have his counselees inform significant others (teachers, parents, or peers) of the outcomes or decisions they arrived at during the counseling process (public commitment).     

Elementary School Counseling and Peer Relations

It was the purpose of this study to compare the effects of counseling and selected guidance techniques upon 5th and 6th grade elementary school students' peer relationships. Sociometric status and teacher ratings of their students' social skills were selected as criteria. Subjects were selected from students who were in the lower half of their classes in sociometric status and who indicated that they wanted to get along better with their peers. From each of 7 classrooms an equal number of subjects was randomly assigned to each of 3 treatment conditions: (1) counseling, (2) teacher-guidance, and (3) control. When the treatment conditions were compared, no statistically significant differences were found among them.     

Perceiving affective content in ambiguous visual stimuli: a component of emotional intelligence

Emotional intelligence involves the accurate appraisal and expression of emotions in oneself and others and the regulation of emotion in a way that enhances living. One aspect of emotional intelligence is the ability to recognize the consensually agreed upon emotional qualities of objects in the environment. One hundred thirty-nine adults viewed 18 reproductions of faces, color swatches, and abstract designs and rated the emotional content of these visual stimuli. Three scores were extracted, including consensual accuracy, amount, and range of emotion perceived. These scores were compared with other aspects of emotional intelligence such as empathy and related to constructs such as alexithymia and neuroticism. A general ability to perceive consensual emotional content in visual stimuli was found, and it was most strongly associated with the ability to respond empathically to others.
