The Diverse Nature of PsychologyThe American Psychological Association has identified 54 divisions within the field of psychology (Plante, 2011). Each division arises from one of seven main perspectives: psychodynamic, behavioral, humanistic, cognitive, sociocultural, biological, and evolutionary. This diversity within psychology allows psychologists to expand in all areas of explanation, evaluation, and diagnosis, which advances the science of psychology across many different subfields. Influence on the main concepts of psychology Diversity has a great influence on the main concepts of psychology. Cognitive-behavioral, psychodynamic, and humanistic perspectives provide various explanations and solutions to psychological disorders. Each perspective uniquely emphasizes factors of human behavior such as cognitive and social factors. Since no two people will have the same exact perception of an event, it is not surprising that two psychologists bring different perceptions to the field.Subdisciplines and SubtopicsClinical PsychologyClinical psychology "focuses on the assessment, treatment and understanding. psychological and behavioral problems and disorders” (Plante, 2011, p. 5). Clinical psychology integrates all aspects of human functioning, including but not limited to intellect, emotions, behavior, biology, and social factors (Plante, 2011). These aspects help a clinical psychologist understand and help a patient facing problems that may arise throughout their life. Social context and culture have a huge impact on behavior. One must become familiar with cultural norms in order to effectively understand symptoms and develop appropriate resources so that the field of psychology can continue to flourish and develop. In the early stages of this field, it was perhaps inconceivable that there could be many different ways to assess a psychological disorder or to assess the simplest human behavior. Clinical psychology assesses human behaviors and emotions in daily life, while I/O psychology assesses human behavior in the workplace. These two areas have a common objective: to improve the quality of life of those who may suffer or have difficulties at work. References Plante, TG (2011). Contemporary clinical psychology (3rd ed.).
