Questions and Answers

You read a paper that studied the object recognition abilities of a group of patients with temporal lobe lesions. That paper describes what sort of cognitive psychology research?

  • Experimental cognitive psychology
  • Cognitive neuroscience
  • Computational modelling
  • Cognitive neuropsychology (correct)

    • You are designing an experiment to test your hypothesis that the strength of the physical connections between the occipital lobe and temporal lobe underlies participants' speed of face recognition. What method from cognitive neuroscience is the most appropriate to use?

  • Electroencephalography
  • vent-related potentials
  • Diffusion tensor imaging (correct)
  • Functional MRI

    • EEG and ERPs have high spatial resolution.

    False

    List the properties of visual neurons.

    <p>Receptive fields, Retinotopy &amp; lateral inhibition.</p> Signup and view all the answers

    Lateral inhibition - when two neurons next to each other are firing one inhibits the other. This leads to enhancement in edges and lines in what we see.
