Environmental influences on cognitive processes

IB Psychology · 2027 Syllabus

Inquiry Question & Thinking Prompt

Can environmental conditions like temperature or poverty affect our cognitive functioning?

Learning Objective

To evaluate the effect of environmental influences on cognitive processes.

📖 Definition / Conceptual Understanding

Environmental influences include both physical factors (temperature, noise, air quality) and sociocultural factors (poverty, nutrition) that affect cognition.

⚙️ Mechanism / Explanation

Physical and social environments impact physiological states (e.g. core body temp, blood sugar) or developmental trajectories, which in turn modulate cognitive functions.

📌 Other Relevant Information

Environmental factors are measurable and potentially controllable. Short-term effects differ from long-term cumulative effects.
