Primary Outcome Measures
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Changes fMRI signal
Time Frame: 1 hour
|
Changes in fMRI signal at encoding will be assessed over an hour long period.
|
1 hour
|
|
Item memory
Time Frame: Up to 90 minutes
|
Item memory will be assessed through performance on delayed memory assessments.
Item memory is determined by the accuracy of memory for individual items and will be expressed as dprime.
|
Up to 90 minutes
|
|
Context memory
Time Frame: Up to 90 minutes
|
Context memory will be assessed through performance on delayed memory assessments.
Context memory is determined by the accuracy of memory for associated contexts and will be expressed as % correct.
|
Up to 90 minutes
|
|
Affect memory
Time Frame: Up to 90 minutes
|
Affect memory will be assessed through performance on delayed memory assessments.
Affect memory is determined by subjective ratings of vividness (1-4), change in ratings from encoding to retrieval of memory (0-3).
The score is averaged where a higher score indicates greater affect.
|
Up to 90 minutes
|
Secondary Outcome Measures

Measure Description |
Time Frame |
|---|---|---|
|
Alcohol motivation
Time Frame: 10 minutes
|
Performance on alcohol taste test following memory retrieval will be assessed using the Alcohol Taste Test (ATT).
The test asks participants to taste the alcohol in each two containers to identify whether the alcohol was the same or different.
The % correct is used to assess this outcome.
|
10 minutes
|
|
Affect - Negative
Time Frame: 10 minutes
|
Self-reported measures of emotional state following drug administration and memory retrieval using the PANAS.
The negative subscale of the PANAS will be used and has a range of 10-50.
Higher scores indicate higher negative affect.
|
10 minutes
|
|
Affect - Positive
Time Frame: 10 minutes
|
Self-reported measures of emotional state following drug administration and memory retrieval using the PANAS.
The negative subscale of the PANAS will be used and has a range of 10-50.
Higher scores indicate higher positive affect.
|
10 minutes
|
|
Neuroendocrine/cortisol reactivity
Time Frame: Baseline to 2 hours
|
Change in salivary cortisol levels following the hydrocortisone/placebo administration.
|
Baseline to 2 hours
