They have heard more words by age 3
What is the center of the bell curve for IQ tests?
100
What is the motivation behind the development of the concept of emotional intelligence?
To provide an alternative to standard IQ tests
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
- Different viewpoints:
- 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
