HP4 Lecture 4

1

Which ONE of the following statements is INCORRECT?


  Perception is the process of transforming and interpreting sensory information to construct meaningful percepts.

  A percept is the phenomenological outcome of the process of object identification.

  Sensation is lower than perception in the cognitive hierarchy.

  Perception is a psychological entity.

  Sensori-neural encoding of incoming physical information is called sensation.


Percepts are the result of the process of perception.

2

Which ONE of the following statements about perceptual organisation is CORRECT?


  Perceptual organisation consists of the principles of exclusive allocation, completion, common fate and identification.

  The principle of exclusive allocation states that a percept should only belong to one sensory element.

  The principle of common fate is most important when the perceptual environment is ambiguous.

  The principle of common fate applies to objects that are moving together.

  Knowledge gained from evolution and learning is not used in top-down processing.

3

Which ONE of the following statements regarding disorders of recognition is CORRECT?


  Impaired identification and recognition most likely indicates a problem with perceptual organisation.

  The inability to copy an image is characteristic of associative agnosia.

  Agnosia can sometimes be a result of a sensory impairment.

  Prosopagnosia is a disorder of cognition in which people are unable to recognise faces.

  Apperceptive agnosia may result in a person being unable to group relevant parts of objects together.

4

Which one of the following statements regarding Luria's brain-behaviour theory is CORRECT?


  The secondary cortical zones are predominantly layers II and IV.

  Reception, integration and analysis of sensory information takes place primarily in the posterior cortical regions.

  Regulation of muscle tone and arousal is primarily the responsibility of the cortical zones.

  Executive function is an important part of sensory information analysis and is the responsibility of the frontal and prefrontal lobes.

  The tertiary zones are responsible for 'gnosis' of objects and display high modal specificity.

5

Which of the following statements regarding the vertical view of cognitive architecture is INCORRECT?


  Mental faculties are mostly genetically determined.

  The principle of modularity states that modules typically have a flexible neural architecture.

  Fodor(1983) stated that modular input systems have a characteristic rate and sequence of development.

  The Ponzo illusion illustrates the "information encapsulation" principle of modular input systems.

  According to the property of domain specificity, damage to nodes results in a very specific pattern of breakdown.

6

Which of the following statements regarding cognitive architecture is CORRECT?


  In the horizontal view of cognitive architecture, mental faculties are domain specific.

  The systems-based and network-based views more closely represent the vertical and horizontal views of cognitive architecture respectively.

  The idea that each area of the brain operates in conjunction with other areas may be described as 'pluripotentiality'.

  Working memory is a functionally distinct process and is unlikely to involve more than one brain area.

  'Mandatory operation' refers to the idea that mental faculties are not domain specific.
