Which term describes the biological process of development that unfolds based on genetic instructions and proceeds in a fixed sequence?

• A. Maturation
• B. Visual Cliff
• C. Rovee-Collier
• D. Halo Effect

Answer: (A)

Maturation is the biological process of development that unfolds according to genetic instructions and proceeds in a fixed sequence. This means that certain developmental milestones tend to appear in a predictable order, guided largely by biology rather than by experience alone. For example, infants usually gain head control before rolling over, then sit up, then crawl, then stand and walk, with the timing of these steps varying between individuals but the order remaining consistent. Environment and practice can influence when a child reaches each milestone, but the sequence itself is built into our biology. Other terms describe different phenomena: Visual Cliff refers to a classic setup used to study depth perception and avoidance of drop-offs, not a fixed developmental sequence. Rove-Collier relates to memory development in infants through a conditioned-kicking paradigm, focusing on learning and memory rather than a predetermined growth timetable. The Halo Effect is a cognitive bias in which an overall impression affects judgments about separate traits, not a developmental process.
