PAPER 2026 QUESTIONS SOLUTIONS GRADED
A+
◉ perception. Answer: the process of organizing and interpreting
sensory information; enabling us to recognize meaningful objects
and events; helping us make sense of the world around us
◉ bottom-up processing. Answer: analysis begins withe the sensory
receptors and works up to the brain's integration of sensory
information
◉ top-down processing. Answer: information processing guided by
higher-level mental processes, as when we construct perceptions
drawing on our experiences and expectations
◉ transduction. Answer: converting stimulus in the environment
into neural signals
◉ selective attention. Answer: The ability to focus on only one
stimulus from among all sensory input
, ◉ inattentional blindness. Answer: failure to see visible objects
when our attention in directed elsewhere
◉ change blindness. Answer: Failing to notice changes in the

information
◉ choice blindness. Answer: the phenomenon of subjects not
realizing that they had been given something that was not "their
choice"
◉ Cocktail party effect. Answer: the ability to attend to only one
voice among many
◉ absolute threshold. Answer: the smallest possible strength of a
stimulus that can be detected in half the time
◉ difference threshold. Answer: smallest change in the intensity of a
stimulus that can be detected (just noticeable difference)
◉ Signal Detection Theory. Answer: Our ability to notice a stimulus
