Neuron

The fundamental unit of the nervous system, responsible for transmitting information. Includes parts like the cell body, dendrites, axon, and myelin sheath.

2
New cards

Synapse

The junction between two neurons where neurotransmitters are released to transmit signals.

3
New cards

Neurotransmitters

Chemical messengers that transmit signals across the synapse from one neuron to another. Reuptake is the process where neurotransmitters are reabsorbed by the sending neuron.

4
New cards

Transduction

The process of converting one form of energy into another. In sensation, it's the conversion of stimuli into electrical signals the brain can understand.

5
New cards

Classical Conditioning

A type of learning where a neutral stimulus becomes associated with a stimulus that naturally evokes a response, eventually causing the neutral stimulus to evoke a similar response.

6
New cards

Operant Conditioning

A type of learning where behavior is strengthened if followed by a reinforcer or diminished if followed by a punisher.

7
New cards

Observational Learning (Bandura)

Learning by observing others; also called social learning.

8
New cards

Includes sensory memory, short-term memory, and long-term memory.

9

A stage theory of moral development ranging from preconventional morality to conventional morality and finally postconventional morality.

Performance increases with physiological or mental arousal, but only up to a point. When levels of arousal become too high, performance decreases.

20

PTSD

A mental health condition triggered by a terrifying event — either experiencing it or witnessing it.

21
New cards

Autonomic Nervous System

The part of the nervous system responsible for control of the bodily functions not consciously directed, such as breathing, heartbeat, and digestive processes. It has two subsystems: the sympathetic (fight or flight) and parasympathetic (rest and digest).

22

The theory set forth by psychologist Albert Bandura that a person's behavior both influences and is influenced by personal factors and the social environment.

26

The theory that we explain someone's behavior by crediting either the situation or the person's disposition.

27

Adjusting one's behavior or thinking to coincide with a group standard.

28
New cards

A set of expectations (norms) about a social position, defining how those in the position ought to behave.

30

A mood disorder causing a persistent feeling of sadness and loss of interest.
