  • 14. 14<br />Lateralization<br />Lateralization: <br />The study of brain functioning that differentiates the left hemisphere from the right hemisphere<br />While both hemispheres appear symmetrical in size and shape, both have varying brain functions<br />
  • 15. 15<br />The Biological Perspective: Peripheral Nervous System<br />Peripheral Nervous System (PNS):<br />A network of nerve fibers leading from the CNS to all parts of the body<br />Somatic Nervous System (SNS):<br />Senses and acts on the external world<br />Relays to the brain information picked up through the sense organs, and transmits the messages to the skeletal muscles<br />
  • 16. 16<br />The Biological Perspective: Peripheral Nervous System<br />Autonomic Nervous System (ANS):<br />Sympathetic Division:<br />mobilizes the body to meet emergencies<br />Parasympathetic Division:<br />slows down metabolism and regulates the organs in such a way that they can do the work of rebuilding their energy supply<br />
  • 17. 17<br />The Biological Perspective: Endocrine System<br />Hormones:<br />Chemical messengers that are released into the bloodstream by the endocrine glands<br />Affect sexual functioning, appetite, sleep, physical growth and development, the availability of energy, and emotional responses<br />
  • 18. 18<br />Evaluating the Neuroscience Perspective:<br />The neuroscience perspective does not hold the absolute answer to causality <br />Not all mental illness can be traced to an organic basis<br />Ethical issues surface around treatment approaches and concerns<br />
  • 19. 19<br />Integrating the Neuroscience and Psychological Perspectives<br />Integrating the Neuroscience and Psychological Perspectives:<br />Emphasis in combining both perspectives might hold new answers to understanding psychopathology<br />Evidence suggests that the environment can alter brain functioning<br />Advances in brain studies offer promising new avenues of research<br />
  • 20. 20<br />Integrating Neuroscience and Psychodynamic Perspectives<br />Integrating Neuroscience and Psychodynamic Perspectives:<br />Psychoanalysis has waned and lost its popularity in recent years<br />Methods used in psychoanalysis are not objective while neuroscience is more detailed<br />Combining both perspectives may hold new keys to understanding development and psychopathology<br />
  • 21. 21<br />Integrating Neuroscience and Cognitive-Behavioral Perspectives<br />Integrating Neuroscience and Cognitive-Behavioral Perspectives:<br />Combining both perspectives might improve the understanding of psychopathology<br />Applications to depression, mania, emotion, personality<br />Research surrounding the Behavioral Approach System or Activation System (BAS)<br />
