PSYC 230 2025/2026 Exam Questions
and Answers | A+ Score Assured



Visual perception - 🧠 ANSWER ✔✔This is the process of encoding,

organizing, and interpreting information that enters the cognitive system

through the senses. The result is an inner representation of a stimulus.


Phonemic restoration effect - 🧠 ANSWER ✔✔A context effect found in

hearing. People tend to fill in missing phonemic information with a sound to

make a word consistent with the meaning in the rest of the sentence.


Long term memory - 🧠 ANSWER ✔✔The part of memory that stores

information on a longer term basis than short-term memory. It is thought to

have unlimited capacity (there is no limit on how much it can hold) and

unlimited duration (some information may be permanently remembered).

, Mental Imagery/Image - 🧠 ANSWER ✔✔The study of how we mentally

represent memories of scenes or pictures, and how we manipulate those

images through rotation and scanning. The question of how images are

Cognitive Psychology - 🧠 ANSWER ✔✔An area of psychology that studies

human intelligence and information processing, in such areas such as

perception, representation, memory, and problem solving.

psychologist who has contributed to research on visual and aural

perception, and also to the understanding of mental imagery. He is also the

creator of the so-called Shepard Scale, an aural illusion that consists of a

musical scale that seems to ascend perpetually.


Transformational Equivalence principle - 🧠 ANSWER ✔✔The psychologist

Ronald Finke has proposed five principles of visual imagery.

__________________________ claims that the way we transform mental

images (as during rotation experiments) corresponds to the same laws of

motion we use when we physically rotate an object in space.
