CHAPTER 1: INTRODUCING COGNITIVE NEUROSCIENCE
Cognition is a variety of higher mental processes such as thinking, perceiving, imagining, speaking acting and
planning. Cognitive neuroscience aims to explain cognitive processes in terms of brain-based mechanisms.
PHILOSOPHICAL APPROAC HES
The mind-body problem is the problem of how a physical substance can give rise to our feelings, thoughts and
emotions.
Dualism: the belief that mind and brain are made up of different kinds of substance (Descartes)
Dual-aspect theory: the belief that mind and brain are two levels of description of the same thing
(Spinoza)
Reductionism: the belief that mind based concepts will eventually be replaced by neuroscientific
concepts.
SCIENTIFIC APPROACHE S
Phrenology is the failed idea that individual differences in cognition can be mapped on to differences
in skull shape (Gall & Spurzheim)
Functional specialism means different regions of the brain are specialized for different functions
Cognitive neuropsychology is the study of braindamaged patients to inform theories of normal
cognition. Cognitive neuroscience methods have three dimensions:
Temporal resolution, the accuracy with which one can measure when an event occurs.
Spatial resolution, the accuracy with which one can measure where an event is occurring.
Invasiveness, whether or not the equipment is located internally or externally.
Cognitive psychology tells us about the structure of information processing but not why information
processing should be configured in that particular way.
Information processing is an approach in which behavior is described in terms of a sequence of
cognitive stages
Interactivity means that later stages of processing can begin before earlier stages are complete. There
are two types of processing:
Top-down processing, the influence of later stages on the processing of earlier ones.
Parallel processing, different information is processed at the same time
Neural network models: computational models in which information processing occurs using many
interconnected nodes, the basic units of neural network models.
Modularity: the notion that certain cognitive processes (or regions in the brain) are restricted in the type of
information they process.
Domain specificity: the idea that a cognitive process (or brain region) is dedicated solely to one particular type
of information.
