Approaches to Cognitive Science

Lecture 1: Introduction to Cognitive Science

The study of the mind

One of the greatest intellectual challenges ...

... attacked from a vast array of different directions.

Cognitive Science seeks a scientific understanding of the mind.

We cannot see our minds working, so we must make inferences from indirect evidence.

What does the mind do?

An apparently infinite variety of things - but at least:

Everyday explanations

We try to explain the actions of others and ourselves all the time ...

... by referring to their intentions, beliefs, emotions etc.

Thus social cognition requires us to try to understand the "mental states" of others.

But ...

... "pop psychology" has limits

Such accounts can be inconsistent, unreliable, specific and not predictive;

they do not deal with many essential cognitive processes - such as how we see, how we speak, how we read.

In short, it is easy to mislead ourselves about how our minds work.

Towards a science of mind

A search for principles which can provide general, reliable accounts with predictive power.

A basis for practical applications:

Tools for the study of mind

need a language to give a common way of conceptualising phenomena;

a framework in which to develop theories (we cannot hope to explain everything at once);

methods for studying mental phenomena.

1. Language

Hard!

Metaphors may help:

Mental representations and their nature are central to much theorising - yet even their existence is hotly debated!

Mental processes are taken to act on representations.

2. Framework

We have to restrict the scope of our ideas. One possible causal framework:

Biological level neurons and the like
down array 
Cognitive level mental representations and processes
down array 
Behavioural level performance of task

3. Methods

introspection

"think-aloud" studies

questionnaires and interviews

experiments

computer simulations

What Characterises Cognitive Science?

The attempt to understand, model, make predictions about and hence explain human behaviour.

The analysis of particular cognitive abilities, e.g. Problem solving, language.

An interdisciplinary approach.
