An urban community centre introduced 'The Green-Sort Screen' above their recycling bins to encourage correct sorting of household waste. Instead of standard instruction posters, this smart screen used automated sensors to detect correctly sorted items, immediately displaying a green checkmark and updating a collective counter: "Our block has saved 18.4 kg of CO2\text{CO}_2CO2 today!" If an item was misplaced, the screen displayed a helpful tip: "Cardboard goes in the blue compartment." During a four-week trial, the rate of correctly sorted materials increased by 48% compared to a control bin with traditional posters, demonstrating that immediate cognitive feedback and clear informational cues can promote pro-environmental habits.
Using your knowledge of psychology, explain how providing real-time cognitive feedback (such as digital tallies and informational tips) can lead to a change in conservation behaviour. Justify your response making reference to the extract.
