The PASS model of intelligence developed by J.P. Das and associates is based on the work of Luria (1973). The three functional units proposed by Luria are:
A. Object sensation
B. Cortical arousal and attention
C. Coding information using simultaneous processes
D. Motivation to pay attention
E. Structuring of cognitive abilities

Correct option is C

The PASS (Planning, Attention, Simultaneous, and Successive Processing) Model of intelligence was developed by J.P. Das, Jack A. Naglieri, and John R. Kirby, based on A.R. Luria’s neuropsychological model of brain function.

Luria proposed that cognition is based on three functional units of the brain:
-First Unit: Cortical Arousal and Attention (B)
-    Related to attention and arousal, which regulate mental activity.
-    Essential for focus and sustained attention during cognitive tasks.
-Second Unit: Coding Information Using Simultaneous Processes (C)
-    Responsible for simultaneous processing of information.
-    Helps in pattern recognition, spatial organization, and holistic processing.
-Third Unit: Structuring of Cognitive Abilities (E)
-    Involves planning, decision-making, and cognitive control.
-    Helps in the organization and execution of goal-directed behavior.

Since B (Attention), C (Simultaneous Processing), and E (Planning & Structuring) are the three functional units of Luria’s model, the correct answer is Option 3: B, C, and E Only.

Information Booster:
PASS Model (Das, Naglieri, & Kirby, 1994): Divides intelligence into four processes:
-Planning (executive functions, problem-solving)
-Attention (focus and arousal regulation)
-Simultaneous Processing (pattern recognition, spatial awareness)
-Successive Processing (sequencing, language comprehension)

Luria’s Three Functional Brain Units:
Unit 1: Regulates attention & arousal (brainstem & subcortex).
Unit 2: Processes information (simultaneous & successive) (occipital, parietal, temporal lobes).
Unit 3: Plans & organizes cognitive behavior (frontal lobes).

Applications of the PASS Model:
-Used in cognitive assessments like the Cognitive Assessment System (CAS).
-Helps diagnose learning disabilities, ADHD, and intellectual functioning.

Difference Between Simultaneous and Successive Processing:
-Simultaneous: Recognizing patterns and spatial relationships.
-Successive: Understanding sequences and language processing.

The PASS model is an alternative to traditional IQ tests, emphasizing cognitive processes over general intelligence.
