  30. Hypothesis
    • A testable prediction, often dirived from a theory, to enable us to accept, reject or revise the theory.
    • Directs our research
  31. Case Study
    A research design that examines one person or a small number of people in depth, over an extended time period to reveal underlying behavioral principles.
  32. Naturalistic Observation
    Watching behavior in real world settings.
  33. Correlational Design/ Research
    • When one trait or behavior accompanies another we say the two correlation.
  34. Experiement
    A controlled condition in which an independent variable is manipulation and changes in a dependent variable are studied.
  35. Experiemental Design includes
    • 1. Random Assignment of participants
    • 2. Manipulation of Independent variables
  36. Experimental group
    Recieves manipulation
  37. Control group
    Does not recieve the manipulation
  38. Independent Variable
    • A factor manipulated by the experimenter.
    • The effect is the focus of the study.
  39. Dependent Variable
    A factor that may change in response to an independent variable.
  40. Standard Deviation
    A computed measure of how much scores vary around the mean.
  41. When is an Observed Difference reliable?
    • 1. Representative samples are better than biased samples.
    • 2.Less-variable observations are more reliable than more variable ones.
    • 3. More cases are better than fewer cases.
  42. Biological Psychology
    Study of brain and behavior
  43. Neuron
    • Individual nerve cell that form the basic structure of the nervous system.
    • Recieves and send messages.
    • "Brains Communicators"
  44. Sensory Neurons
    Carry INCOMING messages to brain/spinal cord
  45. Motor Neurons
    Carry OUTGOING information from CNS to muscles and glands.
  46. Interneurons
    • Carry messages from one neuron to another.
    • 99% of the work
  47. Cell body
    Life suppor center of the neuron
  48. Dedrites
    • Branching extenstions of cell body
    • Recieving portion of neuron.
  49. Axon
    • Sending portion of neuron.
    • Covered by myelin sheath.

  52. Synapse
    Junction between axon tip of sending neuron and the dendrite or cell body of recieving neuron.
  53. Neurotransmitters
    Chemical messengers secreted by neurons whice are released at the synapse and alter activity in the recieving neuron inspecialize in communication.
  54. How do Neurotransmitters influence us?
    They affect certain behaviors and emotions.
  55. Central Nervous System
    Brain and Spinal Cord
  56. Peripheral Nervous System
    • The sensory and motor neurons that connect the CNS to the rest of the body.
    • Nerves extend outside the CNS.
  57. Somatic Nervous System
    Controls the voluntary movements of the body's skeletal muscles and behavior.
  58. Autonomic Nervous System
    • Controls the glands and other muscles of internal organs.
    • Helps us experience and express emotions.
  59. 2 Nervous Systems under Autonomic
    • a. Sympathetic NS- AROUSES the body, mobilizing its energy in stressful situations.
    • b. (Division os the ANS) CALMS the body, conserving its energy, active during rest and digestion.
  60. Nerves
    • Are neural "cables" containing many axons.
    • Part of PNS.
  61. Endocrine System
    • The body's "slow" chemical communication system.

  62. Hormones
    Chemicals secreted by the endocrine glands that produce physical or psychological changes.
  63. Pituitary Gland
    • "Master Gland"
    • Controls the hypothalamus and other bodily glands.
  64. Forebrain( Cerebrum)
    The forward part which is most highly developed area in human brain controls advanced intellectual abilites.
  65. Cerebral Cortex
    • Largest component of the forebrain.
    • Responsible for higher brain function-ability to talk, think, and reason.
  66. Parts of Cerebral Cortex
    • Frontal Lobe-front, motor function, language, abstract thinking, memory
