This book deals with 'Intelligence-Service Psychology'; a recent develop¬ment in the field that arose from the specific conditions of intelligence work and the demands it made on the science of psychology. Intelligence Services acquire and analyse information in order to create a basis from which Governments can make decisions. Intelligence services achieve their goals through human resources, technical proficiency and, to a large degree, by accessing information which is not actually classified. Considering the complexity and dynamics of the work of intelligence services, this volume cannot currently offer a comprehensive or systematic presentation of 'Intelligence-Service Psychology'. It wishes to shed some light on some selective aspects, and to examine some relevant topics as an example of this field of study. 1 Editor’s Preface Sven Max Litzcke – Helmut Müller-Enbergs – Dietrich Ungerer 2 Considerations on a Systematic Approach to Intelligence Work Manfred Mimler 3 The Hour Zero of the Official Information – Training in the German Democratic Republic from a Dissonance-theoretical Point of View Helmut Müller-Enbergs 4 Motivation for Intelligence-Service Work – the German Democratic Republic State-Security Helmut Müller-Enbergs 5 Intelligence Information Gathering and Information Evaluation Dietrich Ungerer 6 Stress in Communication – Gaining Knowledge through the Control of Language Dietrich Ungerer 7 Illegal Migration between Psychology and Intelligence Agencies Thomas Zimmermann 8 Nonverbal Alert Signals – the Diagnosis and Attribution of People’s Credibility Sven Max Litzcke – Max Hermanutz – Astrid Klossek 9 Authors
