Techniques used to study the brain

MRI/brain scans for high-resolution 3D imaging and analyzing energy emission patterns in the brain.

Localization of function in behavior

Different brain structures having specific functions in behavior.

Neuroplasticity

Brain's ability to change by forming or breaking neural connections.

Neurotransmission and its role in human behavior

Neurotransmission is the release of neurotransmitters from a neuron, crossing a synapse to bind with receptors on nearby cells. This process is essential for transmitting signals in the nervous system, affecting physiological functions and behaviors.

Scopolamine

Inhibitory chemical affecting memory formation, antagonist

Neural pruning

Process of the depletion of neural connections in the brain

Formation of neural networks

Development of pathways in the brain, making/breaking synaptic connections

Agonist

Substance enhancing neurotransmitter action, like acetylcholine used for spatial memory encoding

Evolutionary explanation of behavior

Behavior's link to evolutionary theories like natural selection.

Schema Theory

Schema theory is a cognitive framework that explains how individuals organize and interpret information based on pre-existing knowledge structures called schemas, which influence memory encoding and retrieval.

Multi-store Memory model

Memory processing from sensory information transferred into long-term memory.

Thinking and Decision Making

verbal protocols, cognitive process to modify info, theory of reasoned action-behavioral intention, attitudes and subjective norms

Working Memory Model

Includes central executive, phonological loop, episodic buffer, and visuospatial pad to transfer that information into LTM

Phonological Loop

Stores speech-based material in memory.

Reconstructive Memory

Memories influenced by schema, perceptions, and beliefs, not complete memory

Cognitive Biases

System 1 and System 2 thinking, cognitive dissonance.

Flashbulb Memory

Emotional memory influenced by personal consequences.

Social Identity Theory

Social categorization, in/out groups, positive distinctiveness.

Stereotypes

Formed by personal experiences, illusory correlations.

Stereotype Effects

Impact performance, self-fulfilling prophecy.

Cultural Dimensions

PDI, cultural empowerment in the workplace.

Enculturation

Learning skills and norms within one's culture group.

Acculturation

Cultural contact with another culture, assimilation, integration, separation, marginalization.
