psychlotron. org. uk • How might a cognitive psychologist think about phobias and OCD? • Could perceptual processes be different in people that have anxiety disorders? How? Why?
Today’s session We are learning how to. . . Design psychological research studies Interpret the results of studies Use evidence to evaluate theories psychlotron. org. uk We are learning about. . . Cognitive explanations for anxiety disorders
The cognitive approach World Thinking Perception Information Emotion Behaviour psychlotron. org. uk Mind
The cognitive approach • People with anxiety disorders feel anxious because they perceive and understand the world in threatening ways. psychlotron. org. uk – Which sorts of perceptual process might be involved? – How might the biases in people’s thinking play a part?
Cognition and anxiety • ‘Catastrophic’ thinking (CT) • Maladaptive attempts to control CT – Phobia – avoidance, lack of reality testing – OCD – paradoxical effects of suppression psychlotron. org. uk • Tendency to misconstrue world and own responses to it
In pairs. . . – Variables & operationalisation – An alternative hypothesis – A sample – Controls psychlotron. org. uk • Design a study to test the idea that people with an anxiety disorder think differently from those that don’t. • You will need to think about. . .
Now swap designs with a different pair. . . – Will the study allow you to decide whether anxiety patients really do think differently from others? – Have appropriate variables been operationalised and controlled? – Is there anything that might show a false effect or hide a real one? psychlotron. org. uk • Can you identify any flaws in the other pair’s design?
In pairs. . . psychlotron. org. uk • Make at least one improvement to the design of your study.
One possible approach. . . • Spider or flower? (Kolassa et al, 2007) psychlotron. org. uk • We might expect that compared with nonphobics, phobics would be more likely to interpret ambiguous stimuli as threatening
What would be the problems with. . . psychlotron. org. uk • Trying to alter how people think to see if you can make them phobic? • Comparing phobics and non-phobics on any measure of cognition?
