Pharmacology and Rationality Flashcards
Regression Analysis
Looking for relationships between a dependent variable and multiple independent variables
Burghart 2013 GARP
Aim: Explore how decision-making is affected by alcohol consumption
Objectives:
-Ask participants to make choices between bundles of goods, then evaluate choices for GARP violations.
-Ask participants to make choices between “lotteries” and then evaluate choices for independence violations
-Ask participants to make choices between lotteries, then evaluate choices to see if risk preferences vary.
Methods:
-101 participants recruited between 8 pm and 1 am at a bar.
-Measured BAC
-Completed 3 tasks
-Participants were rewarded for one decision at the end
Afriat’s Efficiency Index (AEI) or Critical Cost Efficiency Index (CCEI)
A tool used to measure GARP violations by measuring severity rather than just counting them. Small and large violations are not weighted the same.
or
Measures how much a budget line must be moved toward the origin to eliminate a transitivity violation.
Independence Experiment
A method in which participants are given a choice between visually displayed monetary lotteries. Participants then choose between choice A or B and then choose between choice A and a new lottery that is an even mix of choice A and choice B.
Bedi 2018
Is Utility Maximization compromised by Acute Intoxication by THC or MDMA
Methods:
-15 participants between 21 and 35 with no past negative effects of study drugs and also screened for mental health
-3 sessions, 1 week apart in random order
-Double-blind/double dummy (participants took 2 pills) because MDMA has a faster onset than THC.
Timing:
-180 minutes after THC/control administration
participants underwent scanning
-Participants made 11 choices between money and
social time
NMDA (4-methylenedioxymethamphetamine)
The active ingredient in ecstasy and molly.
THC (delta-9-tetrahydrocannabinol)
The active ingredient in marijuana.
What does a higher number mean on Afriat’s Index?
Fewer GARP violations.
Neuromodulation
The process of influencing the activity of neuronal networks through the alteration of neuronal properties by neuromodulator systems
Neurotransmitters
Chemical messengers that carry signals from a neuron (nerve cell) to a target cell.
Excitatory Neurotransmitters
Messages continue to be passed along to the next cell
Inhibitory Neurotrasnmitters
Messages will not be passed along to the next cell
Modulatory
Affect how cells communicate at the synapse
What are the 4 types of Neurotransmitters?
- Amino Acids
- Monoamine Neurotransmitters
- Peptides
- Acetylcholine
Amino Acid Neurotransmitters
-Glutamate (Most common excitatory neurotransmitter and plays a key role in cognitive function)
-GABA (The most common inhibitory neurotransmitter and regulates brain activity to prevent problems with stress, sleep, depression, and concentration.
-Glycine (Most common inhibitory neurotransmitter in the spinal column)
