Biological Basis of Behavior

Only excitatory uses dopamine as neurotransmitter; inhibitory uses serotonin only

Excitatory neurotransmission involves neurons firing, while inhibitory involves them resting.

Excitatory neurotransmission increases likelihood that action potential will be generated, while inhibitory decreases it.

Excitatory involves electrical signals; inhibitory involves chemical signals only.

Ensuring privacy, confidentiality, and avoiding harm or discomfort for the participants.

Disregarding any discomfort experienced by subjects during experimentation for the sake of results.

Ignoring any legal laws or regulations associated with data interpretation.

Sharing personal details about participants' identities without their approval.

The belief that neurons physically touch each other to transmit information.

The understanding that humans have a tripartite soul.

The notion that mental experiences can be conditioned through association.

The idea that the mind and body are two separate entities.

Myelination slows down impulses forcing axons related with fine-tuned movements into methodical pace.

Myelination increases transmission speed through saltatory conduction enabling more rapid coordination required by intricate motor tasks.

The process actually decreases efficiency by requiring energy maintenance resulting sluggishness.

It interrupts signals intermittently making precise timing difficult during complex muscle interactions.

They stimulate growth and development of new neurons in brain regions responsible for learning and memory functions.

They transmit signals from one neuron to another across synapses.

They make up the physical structure of neurons themselves.

They provide energy for neurons to function efficiently.

Group Therapy

Long-term psychotherapy

Cognitive-behavioral therapy

Brief psychoanalytic therapy

Observing natural variations in neurotransmitter levels among different individuals through correlational studies.

Conducting a randomized controlled trial where one group receives a neurotransmitter inhibitor while another group does not.

Using cross-sectional methods to compare neurotransmitter levels across groups at a single point in time.

Collecting qualitative self-reports from subjects regarding their emotions following exposure to various stimuli.

It reduces levels of neurotransmitter, leading to decreased signal transmission.

It prevents initiation of action potential, ceasing neural communication completely.

It increases levels of neurotransmitter in the synaptic cleft, prolonging its effect on the postsynaptic neuron.

It enhances the speed at which action potential travels down the axon.
