Intelligence is a psychological attribute that involves the usage of cognitive elements to perceive the environment and solve problems.
PASS model- J.P. Das, Jack Naglieri, and Kirby, intellectual activity involves the interdependent functioning of three neurological systems, called the functional units of the brain. These units are responsible for arousal/attention, coding or processing, and planning respectively.
- Arousal/Attention – State of arousal is basic to any behavior as it helps us in attending to stimuli.
- Simultaneous/Successive Processing – Simultaneous processing takes place when you perceive the relations among various concepts and integrate them into a meaningful pattern for comprehension. Successive processing takes place when you remember all the information in a serial order.
- Planning – Planning comes after the information is attended to and processed- allows us to think of the possible courses of action, implement them to reach a target, and evaluate their effectiveness.
