• What is the zygomatic Arch and what can it tell us about smiling?

  the zygomatic arch holds the Muscles around the eyes, when we are genuinely smiling they tense but when we are faking a smile they do not.

• What were the dependant and independent variables in the meerkat study?

  IV: Food type
  DV: Number of meerkats present at each site.

• What theories did the Stroop test lead to?

  Automaticity theory
  Selective attention theory

• What is the selective attention theory?

  Reading requires less attention compared to identifying a colour, that's why it takes us longer to identify the colour of words in incongruent trials.

• What is Aphasia? And what does it affect?

  A language disorder that affects a persons ability to communicate. It is the result of a stroke or brain injury and affects.
  Talking
  comprehending spoken or written language
  Writing
  Using numbers e.g., calculating answers to problems.

• What are the who types of Aphasia? And what are the differences in affects?

  Brocas area
  Wernikes area.
  Brocas is involved with speech production and producing language is made hard while comprehension remains relatively conserved. Wernikes is involved with language comprehension, might speak fluently but language often lacks meaning as comprehension is compromised.

• What is FMRI and how does it help us to study the brain?

  FMRI detects changing in flow of the brain, measures blood flow.
  This is helpful when studying the brain as it is safe/non-invasive,  blood flow is correlated with neuronal activation so we are inferring that more blood flow in an area of the brain mean there is more neural activity.

• What is TMS? How is it helpful and what needs to be done before using TMS?

  A non-invasive technique that disrupts specific brain activity for a fraction of a second, it allows us to investigate the role of the areas of the brain being disrupted in human functioning.
  Participants will do a FMRI before TMS due to everyone having subtle differences in brain structure location so doing a FMRI allows for knowing precisely what region the TMR will be disrupting.

• Contrast temporal and spatial summation

  Temporal summation is when there are lots of different inputs coming in at quick succession and spatial summation is many different inputs coming in at the same time.

• Describe how chemical messengers (neurotransmitters) transfer information from one neuron to the next

  When the action potential reaches the synapse, they the calcium doors open calcium will flow into the cell through diffusion and then when calcium is in the cell some neurotransmitters ventricles will merge with the neuron membrane and open up releasing the neurotransmitters, due to diffusion only some will attach to receptors on the post synaptic cell.
