Understanding College Psychology Vocabulary

This vocabulary set gives you a connected map of how psychologists explain behavior and mental life. It begins with the nervous system. Neurons receive information through dendrites, send signals along axons, and pass chemical messages across synapses.

Neurotransmitters make this communication possible. These small processes matter because thoughts, emotions, movements, habits, and memories depend on activity across large networks of neurons.

The cerebral cortex supports complex abilities such as language, planning, perception, and voluntary action. Neuroplasticity explains why experience can reshape those networks over time.

Sleep and memory show how biology affects learning. Circadian rhythm helps organize cycles of alertness and sleep across roughly one day. Different sleep stages have different roles.

REM sleep is strongly linked with vivid dreaming and emotional processing. Slow-wave sleep is important for physical restoration and some forms of memory strengthening. Adenosine builds up during waking hours and contributes to sleep pressure.

Sleep consolidation describes the way new learning becomes more stable after sleep. When studying, connect this idea to real practice. Spacing study sessions across several days, then sleeping well, usually supports stronger recall than one long late-night session.

The memory terms describe a process rather than one storage box in the brain. Sensory memory holds incoming information very briefly. Working memory is the limited mental space used to hold and manipulate information right now.

Explicit memory includes facts and events that can be consciously recalled. Implicit memory shapes skills and learned responses without requiring deliberate recall. Retrieval is the act of bringing stored information back into awareness.

The hippocampus is especially important for forming many new explicit memories, while the amygdala can make emotional events more memorable. Use examples from your own life to separate these systems clearly.

Learning vocabulary explains how experience changes behavior. Classical conditioning involves learning that one event predicts another. Operant conditioning focuses on consequences that increase or reduce behavior.

Reinforcement makes a behavior more likely, while punishment aims to make it less likely. Extinction occurs when a learned response weakens because the expected outcome no longer appears. Do not treat these terms as moral labels.

Reinforcement does not always mean something pleasant, and punishment does not always mean something harsh. Focus on what happens to the future frequency of a behavior. Build short scenarios and identify the behavior, consequence, and result.

The remaining ideas connect thought, emotion, and stress. Heuristics are quick mental shortcuts, but they can produce cognitive bias. Confirmation bias, availability heuristic, and anchoring show how judgments can be influenced by familiar evidence, memorable examples, or an early number.

Schemas organize knowledge, while assimilation and accommodation describe how schemas handle new information. The sympathetic nervous system and HPA axis prepare the body for threat, including cortisol release and the fight-or-flight response. The parasympathetic nervous system supports recovery.

The hypothalamus helps coordinate these body systems, the limbic system includes important emotion structures, and the prefrontal cortex helps with planning and self-control. Study the deck by drawing links among terms, then explain one everyday example using several words together.
