1) How do the three lists differ? Which one is the most difficult? Which one is the easiest?

2) Which codes do you think are activated in this task?

3) Why do you think one of the lists is more difficult than the others? Can you list the mental operations that are likely to be performed in this task?

STROOP CONDITIONS

TWO ASPECTS OF THE STROOP TASK

1) AUTOMATIC VS CONTROLLED PROCESSES

Two processes are engaged in the Stroop task:

A) COLOR NAMING.
B) WORD READING.

2) RESOLUTION OF A CONFLICT

NORMAN AND SHALLICE'S MODEL

TWO COMPONENTS:

1) CONTENTION SCHEDULING

2) SUPERVISORY ATTENTIONAL SYSTEM (SAS)

Situations that:

1) require planning or decision making
2) require error correction or troubleshooting
3) require to create novel and not well learned links between the input and the action to execute
4) are difficult or dangerous
5) require a response that competes with a strong habitual response
