      - Informed consent
      - Withdrawal rights
      - Deception
      - Confidentiality
      - Voluntary participation
      - Debriefing
  - - - Must have potential benefit and conducted by competent people
    - - Participants cant be exploited
    - - The benefits must justify the risks
    - - Proper regard for the welfare, beliefs and culture of participants.
  - - - Independent variable
        
        Changes to affect the second variable
      - Extraneous variable
        
        May impact the dependent in unintended ways
      - Confounding variable
        
        Impacts the measurements of the dependent variable
      - Dependent variable
        
        Expected to change and measured
    - - Independent variable CAN be manipulated
      - Cause-and-effect relationship can be found
      - Participants can be manipulated
    - - Independent variable CANNOT be manipulated
      - Cause-and-effect relationship CANNOT be found
      - Participants CANNOT be randomly allocated
    - - 1) Recognition of a problem
        
        Discover a problem
        
        2) Collection of information related to the problem
        
        Research the problem
        
        3) Making a hypothesis
        
        Suggest an explanation
        
        4) Testing the hypothesis
        
        Conduct experiment and record data
        
        5) Collection of data from the experiment
        
        Identify the relationship between the independent and dependent variable
        
        6) Make a conclusion
        
        Communicate the conclusion to other researchers
    - - Complete collection of people
    - - Subset of the population
    - - People involved in the study
- - - - The Brain
      - The Spinal Cord
        
        Consists of a cable of nerve fibres
        
        The function is to process information
    - - Transmits sensory information to the CNS
      - Somatic Nervous System
        
        Voluntary skeletal muscle movement
      - Autonomic Nervous System
        
        Involuntary response
        
        Parasympathetic Nervous System
        
        Maintains appropriate level of energy
        
        Physically calms
        
        Sympathetic Nervous System
        
        Alters the activity level during emotional or physical arousal
  - - - Dendrites
        
        A neuron fibre that receives signals
      - Cell Body
        
        Contains the nucleus
      - Nucleus
        
        Control centre of the neuron
      - Axon
        
        Carries information away from the cell body
      - Myelin Sheath
        
        Protects the Axon and assist with speedy delivery
      - Axon Terminals
        
        Fibres that branch out from the end of the presynaptic neuron and connect to the postsynaptic neuron
    - - 1) Action potential travels to the axon terminals
        2) Neurotransmitters are released from the presynaptic neuron
        3) Neurotransmitters travel across the synapse
        4) The transmitters bind with receiving neuron
    - - Electrical impulse passed through the neuron
    - - Electrochemical impulses are transmitted from a neuron to another
    - - Chemicals released from the axon terminals
    - - The process of one neuron passing information to another neuron
      - Synapse
        
        The gap between the pre and post synaptic neurons
        
        Functions:
        Neurotransmitter re-uptake
        Waste removal
  - - - Located at the base of the brain
      - Coordinates reflex actions and voluntary muscle movements
      - Cerebellum
        
        Regulates posture, balance and coordinate fine muscle movements
      - Medulla
        
        Located at the base of the Hindbrain
        
        Controls heart rate, breathing, digestion, and swallowing
    - - Passes information from the spinal cord to the forebrain
      - Sits on top of the Hindbrain
      - Reticular Formation
        
        Network of nerves
    - - Plays a major role in how we think, feel and behave
      - Hypothalamus
        
        Regulates the release of hormones
      - Thalamus
        
        Regulates the level of arousal
      - Cerebrum
        
        Has two hemispheres
        
        Corpus Callosum
  - - - Control movement
