Selective attention
- Definition: Selective attention is the process of focusing on relevant information while ignoring irrelevant information.
- Single Channel Theory (Welford 1968): Some psychologists believe we can only deal with one thing at a time due to our Short-Term Memory's (STM) limited capacity.
- Multi-tasking (Wickens 1980): We can handle multiple tasks simultaneously if they are dissimilar and occupy different parts of the brain. Example: Running with a basketball (motor task) while deciding to pass or shoot (cognitive task).
- Broadbent (1956): All information enters the STM, but we attend to selected stimuli. Unselected stimuli are filtered out, and selected stimuli are compared to information stored in Long-Term Memory (LTM) to make decisions.
- Involuntary Attention: Sometimes attention is involuntary. A sudden loud noise or bright light will attract our attention, likely as a subconscious safety factor.
Response time
- Definition: Response time is the time from the introduction of a stimulus to the completion of the action required to deal with it.
- Components: It comprises Reaction Time (the time from the sudden onset of a stimulus to the beginning of an overt response) and Movement Time (the time it takes to carry out the motor aspects of the performance).
- Factors Affecting Response Time
- Age: Response time increases throughout childhood and adolescence but gets slower as we get older.
- Fitness: Movement time is affected by fitness, particularly power and speed of limb movement.
- Training: Movement time can be improved with training, but reaction time is less easy to improve.
Hick's law
- Definition: Hick's Law states that reaction time increases linearly with the logarithm of the number of stimulus-response groupings. Generally, reaction time increases by about 150 milliseconds every time the stimulus-response groupings are doubled.
- Example: If there are no choices (simple reaction time), the mean times range between 170 and 200 milliseconds. As we increase the number of choices (choice reaction time), the times increase.
