BA – Cognitive Model of Abnormality
• Koster et al (2005)
• Aim: Investigate the role of attention to negative stimuli in
• Procedure: 15 depressed and 15 matched non-depressed
students were identified and given selective attention task.
• They were presented with: Positive (successful, powerful),
Negative (loser, failure) OR Neutral words (crane, paper) for
1.5 seconds each on a computer screen. Half a second after
each word they saw a square on either the left or right of the
screen. Task was press Q square if on the left and 5 square if
on the right. How long they took to identify where the square
appeared was a measure of attention to words.
• SO: The longer they took to find the square the harder they
found to disengage with the word.
• FOUND: depressed participants took an average 12
milliseconds to disengage from negative words than non-
depressed who took only 2 milliseconds.
• CONCLUSION: findings show depressed people attend to
negative stimuli as Beck suggested.
