What is the PASS theory?
Developed by J. P. Das and Jack Naglieri, PASS describes intelligence through four cognitive processes: Planning, Attention, and Simultaneous and Successive processing. It is grounded in the neuropsychological work of Alexander Luria on functional brain systems.
What do the four processes mean?
Planning is forming strategies and solving problems; Attention is focusing and resisting distraction; Simultaneous processing integrates information into a whole; and Successive processing handles information in sequence. Together they describe how a person takes in and uses information.
How is it measured?
PASS is operationalised through the Cognitive Assessment System (CAS), which yields scores for each of the four processes. This gives a process-based profile intended to guide intervention rather than a single global score.
How does PASS differ from g-based models?
PASS emphasises distinct cognitive processes and downplays a single overarching g factor, framing intelligence as a system of brain-based functions. Supporters value its links to neuropsychology and education, while critics note the processes still correlate and the model is less widely adopted than CHC.
