Which theory explains how the order of processing elements in sentences affects language development, focusing on real-time processing?

• A. Processability theory
• B. Noticing hypothesis
• C. Processing instruction
• D. Pattern practice drill

Answer: (A)

Processability theory explains how the order in which sentence elements are processed in real time shapes language development. It claims that learners build their grammar in stages according to what their current processing system can handle while they listen, parse, and produce language. Structures that are easier to process—because they involve fewer dependencies, simpler word order, or less morphosyntactic load—are acquired first. As processing capacity grows, more complex combinations and longer dependencies become manageable, so those elements are learned later. The focus on real-time processing means the sequence of acquisition mirrors what learners can actively parse and produce as they encounter language in context. This perspective contrasts with theories that emphasize noticing (conscious awareness of input), targeted input manipulation, or rote practice. While those ideas highlight different aspects of learning, they don’t specifically account for why certain sentence components come in a particular order based on processing demands in real time.
