psychology

• 5 ethical concepts?

  beneficence, integrity, justice, non-maleficence, respect
• 5 ethical guidelines?

  confidentiality, debriefing, informed consent, use of deception, voluntary participation, withdrawal rights
• 4 lobes of the cortex?

  occipital, frontal, parietal, temporal
• role of the occipital lobe?

  processes visual information, sends it to other parts of the brain for further processing,
• role of the parietal lobe?

  receives and processes somatosensory information, creates a map of body parts, plays a role in interpreting language and words,
• role of the frontal lobe?

  controls responses to complex problems, portions of this lobe play a role in language formation
• role of the temporal lobe?


  regulates memory creation, memory storage, emotion, hearing, involved in organization and sequencing
• types of psychological research methods

  non-experimental, experimental, observational, case study, correlational, developmental.
• non-experimental study


  not dependent on changing variables, to define characteristics of a particular subject,
• observational study

  observing the behavior of subjects in a natural environment, no intervention/manipulation
• case study

  single person, community, or event. learn about an individual to generalize findings to others
• correlational study 


  determine the extent of relationship between two or more variables, good when experiment is not possible, less invasive,
• function of the pons?

  relay system between cerebellum and cerebrum, contains cranial nerves that transfer sensory and motor info to and from face and brain
• function of the midbrain?


  controls reflex patterns associated with hearing and vision
• function of medulla oblongata?

  control vital bodily functions, breathing and heartbeat
• function of the cerebellum?

  two hemispheres left and right, regulates and coordinates movement, posture, and balance
• what is the function of the corpus callosum?

  connects right and left hemispheres, makes sure info gets to both sides
• function of the cerebral cortex

  outer 3mm of 'grey matter', 70% of neurons here, controls most bodily functions
• Sperry's split brain study

  patients with epilepsy underwent a commissurotomy (brain cut in half through the corpus callosum) the two hemispheres were separated and could not communicate. showed researchers what the two hemispheres controlled and how they affected the function of body
• structure of neuron?

  cell body(soma), dendrite, axon, myelin sheath, axon terminal, synaptic bulb, schwann cell, node of ranvier

  
• 3 main parts of nervous system?


  brain, spinal cord, nerves
• The peripheral nervous system (PNS) includes all nerves outside the CNS.
• steps of nerve impule
• what happened to phineas gauge?

  • 1948, metal pole through cheek up through the frontal lobe
  • he survived and walked around to get help straight after the accident
  • accident affected his personality and behavior, he didn't care about the things he did before
  • the first source that showed the frontal lobe was involved in personality and that different parts of the brain are involved in different things
• Walter freeman lobotomy

  • started on chimps that underwent a frontal lobotomy
  • developed long instrument to sever connection to frontal lobe
  • technique was the transorbital lobotomy
  • 5000 lobotomies performed
• what is the function of the Wernicke's area?

  responsible for interpretation of language/speech
• what is the area of the Broca's area?

  responsible for formation of language/speech
• what is the role of the auditory cortex?

  receives auditory information like pitch, tone, sound quality
• what is the role of the visual cortex?

  receives visual information
• two main parts of the nervous system?

  central and peripheral nervous system (cns and pns)
• two parts of the peripheral nervous system?

  sensory and motor divisions (afferent and efferent)
• two parts of the motor division (efferent)

  somatic and automatic nervous systems
• two parts of the autonomic nervous system?

  sympathetic (fight and flight) and parasympathetic (rest and digest)
