Childhood loss and disharmony: later effects on personality and psychopathology

In a comparison of psychiatric inpatients and medical controls parental loss in childhood was not a differentiating factor. Psychiatric inpatients, however, had more disturbance in their home background.In the psychiatric group a disturbed childhood background was associated, on the Eysenck Personality Questionnaire, with abnormal scoring on P in both sexes, and N in males. There was, however, no specific association with psychiatric diagnosis.     

Post traumatic stress disorders

A clinical overview of the Post-Traumatic Stress Disorders (PTSD) is presented emphasizing altered qualities of experience and behavior. A schema of human psychological responses to stressful life events is reviewed as an introduction to the extensive development of concepts of pathological stress response syndromes: Post-Traumatic Stress Disorders; post-traumatic stress disorder, chronic type; delayed Post-Traumatic Stress Disorder. An illustrative case history is presented. The potential development of PTSD in individuals experiencing less than overwhelming stressors is conceptualized.     

Introduction to two-dimensional Fourier analysis

The application of two-dimensional Fourier analysis provides new avenues for research in visual perception. This tutorial serves as an introduction to some of the methods used in two-dimensional Fourier analysis and an introduction to two-dimensional image processing in general.     

A microcomputer-based system for evoked-potential augmenting/reducing measurements

Evoked-potential measurements can readily be implemented on a microcomputer. We present as an example a system for obtaining an evoked-potential augmenting/reducing measure using the Apple II microcomputer. Specialized features of the PASCAL program and peripheral equipment are described.     

Toward a science of history

The scientific status of History was compared to other sciences in the critical areas event selection, investigative operations, and theory construction. First, in terms of events studied, history is regarded as a quasi-scientific study of past events. However, viewed from the science of behavior's perspective of what historians actually do, history becomes a study of current records. As a study of currently existing records, not the non-existent past, history has potential to become a science. Second, like other scientists, historians may undertake manipulative investigations: they can locate the presence and absence of a condition in records and thereby determine its relation to other recorded phenomena. A limitation has been the lack of quantification that results from emphasis on the uniqueness of things rather than on their communality. Scientific training would facilitate viewing similar things as instances of a larger class that could be counted. Another limitation that cannot be easily overcome is the inability to produce raw data. This limitation has created problems in theoretical practices, the third area of comparison, because theoretical constructions have frequently been substituted for missing data. This problem too could be reduced through scientific training, particularly in other behavior sciences. An authentic science of history is possible.
