Bio psychology extended answer questions

• What are the four lobes of the cortex?

  Frontal, Parietal, Temporal, Occipital
• What is one function of the frontal lobe?

  It controls voluntary movements and decision making.
• What is one function of the parietal lobe?

  It processes sensory information such as temperature and touch.
• What is one function of the temporal lobe?

  It is responsible for understanding speech and interpreting auditory information.
• What is one function of the occipital lobe?

  It is responsible for visual perception and processing.
• Which functional area of the cortex did Kadek injure?

  Primary visual cortex.
• Why is Kadek experiencing issues with visual stimuli?

  He has injured the primary visual cortex, affecting visual processing.
• What is the difference between still images and dynamic images?

  Still images are static, while dynamic images change in real time.
• Name two neuroimaging techniques that produce still images.

  Computed tomography (CT) and magnetic resonance imaging (MRI).
• How does computed tomography (CT) work to produce images?

  1. ray beams revolve around the patient's body to form images based on tissue density.
• How does magnetic resonance imaging (MRI) work to produce images?

  A strong magnetic field aligns protons, and radio waves cause them to emit signals as they realign.
• Which neuroimaging technique should doctors use to assess Kadek's brain damage?

  MRI, as it provides detailed images of soft tissue.
• What is a structured interview?

  A structured interview uses a set of pre-established questions without deviation.
• What is a semi-structured interview?

  A semi-structured interview uses pre-established questions but allows for follow-up questions.
• What is one strength of using a structured interview?

  It reduces bias from the researcher due to standardization of questions.
• What is one limitation of using a structured interview?

  The depth of data is limited as no follow-up questions are permitted.
• Give an example of a qualitative question researchers could ask.


  What do you think about individuals who choose to wear helmets when riding bikes?
• Give an example of a quantitative question researchers could ask.

  How many times have you been skateboarding without a helmet?
• What are the three functions of the left hemisphere of the brain?

  Controls right side movement, processes sensory information from the right side, and produces speech.
• What are the three functions of the right hemisphere of the brain?

  Controls left side movement, processes sensory information from the left side, and draws pictures.
• What specific functional area of the brain has Sam likely injured?

  Primary motor cortex.
• What structure connects the two hemispheres of the brain?

  The corpus callosum.
• What method did Sperry use in his research involving humans?

  He tested participants who had their corpus callosum severed and asked them to focus on a dot on a screen.
• What were the findings of Sperry's research?

  Participants could verbally report objects shown to the right but not to the left, though they could draw them.
• What does the term experimenter effects refer to?

  The expectations and behaviors of the researcher that may bias results.
• How can experimenter effects be reduced?

  By having an assistant interact with participants and using a standardized procedure.
• What are the key functions of the brain's left and right hemispheres?

  Left Hemisphere:

  • Controls right side movement
  • Processes sensory information from the right side
  • Responsible for producing speech

  
  

  Right Hemisphere:

  • Controls left side movement
  • Processes sensory information from the left side
  • Responsible for the ability to draw pictures
• What are the differences between structured and semi-structured interviews?

  Structured Interview:

  • Uses pre-established questions
  • No deviation allowed

  
  

  Semi-Structured Interview:

  • Uses pre-established questions
  • Allows for follow-up questions
• What are the strengths and limitations of structured interviews?

  Strengths:

  • Reduces researcher bias
  • Standardization of questions

  
  

  Limitations:

  • Limited depth of data
  • No follow-up questions permitted
• What are the neuroimaging techniques used to assess brain injuries?

  • Computed Tomography (CT): Uses X-ray beams to create images based on tissue density.
  • Magnetic Resonance Imaging (MRI): Uses magnetic fields and radio waves to produce detailed images of soft tissue.
