High School Psychology Vocabulary

Understanding High School Psychology Vocabulary

This vocabulary set maps the main levels of psychology, from brain cells to everyday choices. Psychology studies behavior and mental processes, but those processes do not come from one single cause. A thought, feeling, or action can involve the nervous system, past learning, current surroundings, and social expectations.

The biology terms help explain how information moves through the brain. Neurons receive and send signals. Dendrites, axons, synapses, and neurotransmitters describe parts of that communication system.

The cerebral cortex and other brain areas describe larger systems with specialized jobs. Neuroplasticity connects the levels because experience can strengthen, weaken, or reorganize brain connections over time.

Sleep and stress show that the brain works with the whole body. Circadian rhythm helps set a daily pattern for alertness and sleep. Different sleep stages, including REM sleep and slow-wave sleep, support different forms of recovery and memory processing.

Adenosine helps explain why sleep pressure builds during the day. Sleep consolidation connects sleep to learning because recently practiced information can become more stable after rest. Stress terms show another body-brain system.

The sympathetic nervous system prepares the body for rapid action. The parasympathetic nervous system supports calming and recovery.

The HPA axis and cortisol help explain longer-lasting stress responses. These terms matter because stress can change attention, sleep, memory, and decision making.

Memory and learning terms explain how experiences become habits, knowledge, and expectations. Sensory memory briefly holds incoming sights and sounds. Working memory is the limited mental space used to hold information while thinking about it.

Explicit memory involves information a person can intentionally recall. Implicit memory influences behavior without deliberate recall. Retrieval is not a simple playback process.

Each act of remembering can be affected by attention, emotion, and later information. Classical conditioning explains learning through associations. Operant conditioning explains learning through consequences.

Reinforcement can make a behavior more likely, while punishment can reduce a behavior. Extinction shows that learned responses can fade when the old pattern no longer occurs. These ideas help explain studying, fears, routines, and habits.

Thinking vocabulary focuses on useful mental shortcuts and their limits. Schemas are organized expectations built from past experience. Assimilation fits new information into an existing schema.

Accommodation changes the schema when the old one no longer works. Heuristics save time, yet they can produce cognitive bias. Confirmation bias can lead a person to notice evidence that supports an existing belief.

The availability heuristic can make vivid or recent examples seem more common than they are. Anchoring can make an early number or idea influence later judgment. Study these terms as connected stories rather than isolated cards.

Draw a neuron signal path. Compare stress systems in a two-column chart. Create one real example for each memory type, learning process, and bias.

Then explain why the example fits, using the vocabulary precisely. That practice builds retrieval skills and reveals which terms still need review.
