Study Notes

The Mind-Body Problem

The mind-body problem is a philosophical question about the nature of the mind and its connection to the body
- Different viewpoints:
  - Monism: only one kind of substance in the universe
  - Materialism: everything that exists is physical
  - Idealism: everything is mental
  - Dualism: existence of both mental and physical substances
  - Functionalism: emphasizes function and how things produce their effects
Functionalism:
- holds that each type of mental state is identical with a particular type of neural state
- tends to be associated with materialism, but is officially neutral between materialism and dualism
- results in a high-level understanding that can be implemented in multiple different ways

Intelligence and the Physical Symbol System (PSS) Hypothesis

The physical symbol system hypothesis:
- proposed by Herbert Simon and Allen Newell in 1975
- states that intelligent behavior essentially involves transforming physical symbols according to rules
- implications:
  - anything capable of intelligent action is a physical symbol system
  - machines can be constructed that are intelligent
  - rule-governed thinking = manipulation of symbolic representation structures

Consciousness

Types of consciousness:
- Access consciousness (A-consciousness): pertains to accessibility of information
- Phenomenal consciousness (P-consciousness): pertains to how and why we experience the world as we do
The hard problem of consciousness: why and how sentient organisms have qualia or phenomenal experiences
Integrated information theory (IIT):
- addresses the question of phenomenal consciousness
- suggests that consciousness arises from neural integration and complexity
- the more information that is shared and processed between many different components of the brain in response to a single experience, the higher the level of consciousness

Neural Correlates of Consciousness

Two main theories:
- Global Neuronal Workspace Theory (GWT): consciousness emerges when incoming sensory information is broadcast globally to multiple cognitive systems
- Integrated Information Theory (IIT): consciousness arises from neural integration and complexity
Zap and zip technique: a method to probe whether someone is conscious or not, using TMS and EEG sensors to measure the brain's response to a pulse of magnetic energy

Intelligence and IQ Tests

Intelligence: relates to consciousness and the ability to understand meaning
IQ tests:
- dominated the field until the last century
- measure verbal comprehension, visual-spatial skills, and working memory
- criticized for cultural and other biases, and for assuming that intelligence is innate and fixed
