Biopsychology examines the relationship between the brain, behavior, and mental processes. Key terms include:

  • Neurons: specialized cells that transmit electrical and chemical signals in the nervous system.
  • Neurotransmitters: chemical messengers released by neurons that communicate with other neurons or target cells such as muscles or glands.
  • Brain structures: the brain comprises various areas, each with specific functions, such as the cerebellum for balance and coordination and the amygdala for fear and aggression.
  • Brain plasticity: the ability of the brain to reorganize and adapt to changing circumstances, such as after injury or learning.

Consciousness refers to our awareness of ourselves and the environment and includes various states and levels. Key terms include:

  • Circadian rhythms: the internal biological clock that regulates our sleep-wake cycle and other bodily processes.
  • Sleep stages: we go through several stages of sleep, including non-REM and REM sleep, with characteristic changes in brain waves and bodily functions.
  • Altered states of consciousness: these include hypnosis, meditation, and drug-induced states that alter our perception and awareness.


Learning involves acquiring new knowledge, skills, or behaviors through experience, observation, or instruction. Key terms include:

  • Classical conditioning: a type of learning where a neutral stimulus (such as a bell) becomes associated with an innate or unconditioned stimulus (such as food) to elicit a reflexive response (such as salivation).
  • Operant conditioning: a type of learning where the consequence (such as reinforcement or punishment) of a behavior determines its likelihood of being repeated.
  • Observational learning: learning by watching and imitating others, as demonstrated by Bandura’s famous Bobo doll experiment.


Memory involves the encoding, storage, and retrieval of information over time. Key terms include:

  • Sensory memory: the brief storage of sensory information such as sights and sounds before it is processed into short-term memory.
  • Short-term memory: the temporary storage of information for immediate use, such as remembering a phone number.
  • Long-term memory: the relatively permanent storage of information, such as remembering events from childhood.
  • Retrieval: the process of accessing stored information, such as recalling a name or a date.
