Physio

• and women can get the X-linked ones
• gene is present in both the sexes
• In the presence of hormones, sex-limited genes are activated
• Biological psychology


  study of the Biology of behavior, nervous system, hormones and genetics
• Relationship between mind and body


  neural mechanisms, and the influence of heredity on behavior
• Biological Approach


  • Behavior to be as a consequence of our genetics and physiology
  • Examines thoughts, feelings, and behaviors from a biological and thus physical point of view
  • all that is psychological is first physiological
• Comparative method


  • Animal can be studied and compared
  • Help in the search to understand human behavior
• Physiology


  • How the nervous system and hormones work, how the brain functions, how changes in structure and/or function can affect behavior
• Investigation of Inheritance


  • What an animal inherits from its parents, mechanisms of inheritance (genetics)
• Physiological Explanation


  • Behavior to an activity of the brain or other organs
  • Mechanics of the body the chemical reaction that allows hormones to trigger brain activity and the path by which brain activity controls the movement of muscles through contractions
• Functional Explanation


  • Why a behavior evolved in the way that it did
  • Within a small population a gene that spreads by pure accident is called a genetic drift
  • The larger the population or community the less impact or powerful the genetic drift is
• Ontogenetic Explanation


  • Development of a behavior or structure
  • Maps the influences of nutrition, genes, experiences, and the correlations or interactions of these factors in producing behaviors
• Evolutionary Explanation


  Looks at a behavior or structure by way of evolutionary history
• Consciousness


  Your individual awareness of your unique thoughts, memories, feelings, sensations, and environment
• Consciousness is the awareness of yourself and the world around you
• Conscious experiences are constantly shifting and changing
• Mind-body dualism


  The idea that while the mind and body are separate, they do interact
• Introspection


  A process used by structuralists to analyze and report conscious sensations, thoughts, and experiences
• Consciousness


  Compared to a stream; unbroken and continuous
• Introspection is a method of observation and mental examination of one's own conscious processes
• Biological psychology


  The study of the biology of behavior; it focuses on the nervous system, hormones, and genetics
• Biological psychology


  Examines the relationship between mind and body, neural mechanisms, and the influence of heredity on behavior
• Biological approach


  Believes behavior to be a consequence of our genetics and physiology
• The biological approach is the only approach in psychology that examines thoughts, feelings, and behaviors from a biological and thus physical point of view
• All that is psychological is first physiological. All thoughts, feelings & behavior ultimately have a biological cause
• Ways a biological perspective is relevant to the study of psychology

  • Comparative method - different species of animal can be studied and compared
  • Physiology - how the nervous system and hormones work, how the brain functions, and how changes in structure and/or function can affect behavior
  • Investigation of inheritance - what an animal inherits from its parents, mechanisms of inheritance (genetics)
• Biological explanations of behavior


  • Physiological Explanation
  • Functional Explanation
  • Ontogenetic Explanation
  • Evolutionary Explanation
• Consciousness


  Your awareness of your unique thoughts, memories, feelings, sensations, and environment
• Your conscious experiences are constantly shifting and changing
• Mind-body dualism


  The idea that while the mind and body are separate, they do interact
• Structuralists used a process known as introspection to analyze and report conscious sensations, thoughts, and experiences
• Integrated Information Theory


  Looks at consciousness by learning more about the physical processes that underlie our conscious experiences
• Global Workspace Theory


  Suggests that we have a memory bank from which the brain draws information to form the experience of conscious awareness
• Chromosomes


  Structures in the nucleus of a cell containing DNA coiled around histone proteins
• Human beings have 46 chromosomes (23 pairs)
• Types of human chromosomes


  • Autosomes
  • Sex chromosomes
• Chromosomal abnormalities can result in genetic conditions such as Down syndrome
• Sex-linked genes


  Genes that are carried by either sex chromosome
• Men normally have an X and a Y combination of sex chromosomes, while women have two X's
• 1. linked recessive traits


  Primarily expressed in the observable characteristics, or phenotype, of men because men only have one X chromosome
