Psychology Exam 1

  1. Scientific Method
    Procedure to gather and analyze information to test and idea or hypothesis.
  2. Image Upload 25 Steps of the Scientific Method.
    • 1)find the issue
    • 2)form a testable hypothesis
    • 3)chose an appropriate strategy
    • 4)conduct the study
    • 5)analyze to support or reject the hypothesis
  3. Psychoanalytic Theory
    segmund theory that people like animals share the sexual and aggressive primitive urge but unlike animals humans think and reason to be approved by other people.
  4. Behaviorism
    study based on observable responses and behavior
  5. Humanism
    study that people posses inner resources for growth and development and to make healthier choices.
  6. Cognative Psychology
    study of the mental process such as reasoning and problem solving
  7. Humanistic Perspective
    behavior comming from free will and ones choices based on self concept and self esteem.
  8. Eelectic Approach
    integrates or combines several perspectives to provide a more complete or complex picture of the behavior.
  9. Basic Research
    focuses on uncovering the specifics about a behavior (chemicals involved in memory)
  10. Applied Research
    solves a problem (uses the findings in basic research). how to treat something better (depression)
  11. Naturalistic Observation
    conducting research in the environment which the behavior typically occurs.
  12. Correlation
    studies test the relationship between two or more variables (tv & violent behavior)
  13. Positive + correlation
    one variable increases and the second tends to increase and vice versa
  14. Negative - correlation
    one variable increases the other decreases or the inverse relationship. (opposite directions)
  15. Experiment
    research method used to test casual hypothesis where variables are controlled or manipulated and participants are randomly assigned.
  16. Independent Variable
    variable that the experimenter manipulates (the cause in the experiment)
  17. Dependent Variable
    measures any result of manipulating the independent variable (the Effect)
  18. Confounding Variables
    variables that can be problematic and have to be controlled anything effecting the outcome of the experiment that shouldnt.
  19. Institutional Review Board
    The board insures that research is ethical and follows guidelines.
  20. Debriefing
    Full disclosure by the researcher to inform participants of the true nature of the researcher.
  21. Transduction
    conversion of environmental stimuli into a form your nervous system can process (light bouncing off a page being able to read it)
  22. Absolute Threshold
    the minimum intensity of a stimulus that can be detected 50% of the time
  23. Subliminal
    intensity of a stimulus below the absolute threshold and the participant isn't conciously aware of the stimulus.
  24. Visible Spectrum
    spectrum of light visible to the human eye 360nm to 750nm
  25. Pupil
    behind the cornea the black opening is a hole in the iris where light passes through the eye.
  26. Lens
    behind the iris and the pupil is the lens a clear and attached to the eye by strong ciliary muscles.
  27. Retina
    surface that lines the inside back of the eyeball that transduces light into neural signals.
  28. Rods
    light sensitive cells of the retina that pick up any level of light energy and convert it to neuro signals.
  29. Cones
    sensitive to specific color lights and send signals to the brain about specific colors being seen.
  30. Optic Nerve
    composed of the axons of the ganglion cell conveys visual signals from the retina to the brain.
  31. Pitch
    the frequency a sound heard...the higher the frequency the higher the pitch.
  32. Frequency
    measured in Hz is the number of cycles that occur during a given amount of time
  33. Loudness
    sound as the amount of pressure the compressed waves of air exert on the eardrum.
  34. Decibles
    measure unit for the loudness of a sound.
  35. Cochlea
    Curled fluid filled tube that looks like a snail that holds the basilar membrane. transduction of neural impulses happens here.
  36. Basilar Membrane
    lined with hair cells which transduce sound waves into action potentials.
  37. Hair Cells
    Neurons grown out of the basilar membrane transduce sound waves into action potentials.
  38. Auditory Nerve
    carries information from the inner ear to the brain.
  39. Gustation
    sense of taste; foods must be broken down by our saliva.
  40. Pheromones
    airborne chemicals released form glands and detected by vomeronasal organs.
  41. Retinal Disparity
    our eyes are slightly apart and get two different images and inform the brain the distance of the stimuli (depth perception)
  42. Gestait Approach
    the whole of perception is better understood than trying to piece the parts in perception together.
  43. Figure Ground 1
    we pull the stimuli forward and push everything else into the background (ground) (most important principle)
  44. Clsoure
    we tend to finish shapes even when they arent closed (shapes)
  45. Proximity
    we group close objects together during perception.
  46. Similarity
    we group like objects together during perception
  47. Good Continuation
    perceive stimuli that seem to follow one another as being part of a continuing pattern. (camo)
