• C. The study of how physical objects move and interact in the environment
• D. A branch of medicine focused exclusively on treating mental illness

Why: Cognitive science is interdisciplinary, combining multiple fields to understand how the mind represents, processes, and uses information.

• A. Transduction ✓
• B. Attention
• C. Memory encoding
• D. Inference

Why: Transduction is the process by which sensory receptors convert physical energy from the environment into electrical neural signals that the brain can process.

• A. The ability to remember information for long periods
• B. The ability to focus on certain stimuli while ignoring others ✓
• C. The ability to perform multiple complex tasks simultaneously without any loss of performance
• D. The ability to recognize faces in photographs

Why: Selective attention is the cognitive process of concentrating on specific information while filtering out irrelevant stimuli, such as focusing on one conversation in a noisy room.

• A. People becoming more social after consuming alcohol
• B. The ability to tune into one's own name or a relevant conversation even when surrounded by many other voices ✓
• C. The tendency to forget conversations held at parties
• D. Hearing loss caused by prolonged exposure to loud music

Why: The cocktail party effect demonstrates selective attention: despite background noise, people can focus on one voice and often notice when their own name is mentioned elsewhere.

• A. Sensory information traveling from the eyes to the visual cortex
• B. Prior knowledge, expectations, or context shaping how sensory information is interpreted ✓
• C. Visual information being processed from the top of the visual field downward
• D. Neural signals traveling from the spinal cord up to the brain

Why: Top-down processing uses existing knowledge, expectations, and context to interpret sensory input, in contrast to bottom-up processing, which builds perception from raw sensory data.

• A. The study of how the brain's physical structure develops over a lifetime
• B. An interdisciplinary field that studies the mind and its processes, drawing on psychology, neuroscience, linguistics, computer science, philosophy, and anthropology ✓
• C. The study of animal behavior in controlled laboratory settings
• D. The application of medical treatments to mental disorders

Why: Cognitive science is interdisciplinary, combining several fields to understand how the mind represents, processes, and uses information, including perception, memory, language, and reasoning.

• A. Perception
• B. Attention
• C. Memory ✓
• D. Motivation

Why: Memory refers to the cognitive processes of encoding information, storing it over time, and retrieving it when needed. These stages are central to learning.

• A. Long-term memory
• B. Procedural memory
• C. Semantic memory
• D. Sensory memory ✓

Why: Sensory memory briefly holds raw sensory input, such as an image or sound, for a fraction of a second to a few seconds. Information that receives attention moves on to short-term or working memory.

• A. Studying all material in one long session the night before an exam
• B. Reviewing information at increasing intervals over time to strengthen long-term retention ✓
• C. Memorizing information while physically moving through a space
• D. Repeating information immediately after first hearing it, many times in a row

Why: Spaced repetition spreads study sessions across time, which research shows produces stronger and more durable long-term memory than massed practice, or cramming.

• A. Observational learning
• B. Classical conditioning ✓
• C. Operant conditioning
• D. Implicit learning

Why: Classical conditioning occurs when a neutral stimulus becomes associated with a meaningful stimulus, eventually triggering a learned response. Pavlov's experiments with dogs are the classic example.

• A. The study of the chemical composition of the brain only
• B. An interdisciplinary field that studies the mind and intelligent processes, drawing on psychology, neuroscience, linguistics, computer science, philosophy, and anthropology ✓
• C. The study of animal behavior in natural environments
• D. The clinical treatment of mental illness through medication

Why: Cognitive science is interdisciplinary, combining several fields to understand how the mind represents, processes, and uses information, including perception, memory, reasoning, and language.

• A. Only spoken words used in everyday conversation
• B. A structured system of symbols, rules, and meanings used to communicate and represent thought ✓
• C. Written text found in books and documents
• D. Body movements used to express emotion

Why: In cognitive science, language is studied as a rule-governed symbolic system that connects sounds or signs to meanings and allows humans to express and reason about thoughts.

• A. Nativism
• B. Behaviorism
• C. Linguistic relativity (the Sapir-Whorf hypothesis) ✓
• D. Dualism

Why: The Sapir-Whorf hypothesis, also called linguistic relativity, proposes that language shapes or influences thought. Modern research finds evidence for weaker versions of this idea, such as effects on attention and memory.

• A. B.F. Skinner
• B. Ivan Pavlov
• C. Noam Chomsky ✓
• D. Jean Piaget

Why: Noam Chomsky argued that children are born with a Universal Grammar, an innate knowledge of linguistic structure that helps explain how they acquire complex language quickly despite limited input.

• A. A physical object stored in memory
• B. A mental representation that groups together objects, events, or ideas sharing common features ✓
• C. A random sensory experience with no meaning
• D. A spoken sentence used in conversation

Why: Concepts are mental categories or representations that allow us to organize experience, for example recognizing that a robin and a penguin are both birds despite their differences.

• B. The study of chemical reactions within the human body
• C. The study of social behavior in large groups

• A. A mental shortcut that simplifies complex judgments ✓
• B. A type of brain scan used in laboratories
• C. A formal logical proof with guaranteed accuracy

• B. To avoid studying human choices altogether
• C. To understand how people actually make decisions, including the influences and errors involved ✓
• D. To train computers to replace human judgment entirely

Why: Cognitive science studies how people actually reason and decide, including the mental processes, biases, and environmental factors involved, rather than assuming idealized rational behavior.

• A. Geology
• B. Neuroscience ✓

• A. Dendrite alone
• B. Axon terminal releasing neurotransmitters at a synapse ✓
• C. Glial cell
• D. Myelin sheath

Why: Neurons communicate primarily at synapses, where axon terminals release neurotransmitters that bind to receptors on neighboring neurons, transmitting signals across the gap.
