Eating Behaviors
Eating a large amount of food and feeling a sense of loss of control
What is a binge? (Binge episode)
Participants with impaired glucose regulation performed more poorly on this attentional bias task
What is the Stroop Word-Color Task?
The Stroop Task and this behavioral construct were found to be associated with future weight gain.
What is Depression?
This neuromodulation technique does not activate neurons but instead, enhances neuronal excitability
What is tDCS?
This subscale on the Three Factor Eating Questionnaire (TFEQ) measures “the intent to restrict food intake to control body weight”
What is The Restraint Sub-Scale (Restrained Eating)?
The tendency to overeat in response to different stimuli. Also the name of a subscale on the TFEQ
What is Disinhibition?
Error reductions on this task were observed following active tDCS, and are thought to reflect an improvement in response inhibition
Go No/Go task
A condition of limited or uncertain access to adequate food and we have shown is associated with binge eating, restrained eating and overeating on the vending machines.
What is food insecurity?
Used to capture repeated, real-time assessment in the participants’ natural environment
What is EMA (Ecological Momentary Assessment)
A subjective measure of social status
What are the SES Ladders?
This pattern of eating was associated with increased food intake on the vending machines and weight gain over time, as well as higher 24-h RQ, higher CHOX and lower LIPOX
What is Nighttime Eating?
This cognitive performance task measures decision-making and is associated with higher body fat, higher leptin levels and anhedonia.
What is the Iowa Gambling Task?
After receiving active tDCS, participants ate fewer calories on which test?
What is Snack Food Taste Test?
What is a Visual Analogue Scale (VAS)?
The only two studies on the 5th floor that did/do not include administration of a battery of questionnaires
What are JPP and the 5YR?
Individuals with obesity have less activation following a meal in this brain region
What is the Left Dorsolateral Prefrontal Cortex?
This construct was found to be associated with kcal intake on the vending machines and was moderated by restraint scores
What is perseveration? (on the WCST)
It is NOT associated with being on a weight loss diet, hunger or weight status
What is adherence?
A hormone often associated in the literature with stress reactivity, abdominal obesity and increased food intake
What is Cortisol?
Measures "loss of interest or pleasure in things" and is associated with long-term weight gain
What is Anhedonia (PAS: Physical Anhedonia Scale)?
This controversial term/construct suggests that highly palatable foods trigger the same reward and pleasure centers of the brain as other drugs like cocaine and heroin
What is Food Addiction?
This working memory task, has only been administered in a few studies and the data have not yet been analyzed
What is the n-back test?
Lower cognitive restraint, higher disinhibition, and greater susceptibility to hungers cues were associated with this chamber measurement
What is (higher) Energy Expenditure?
In the biggest mess-up in 5th floor clinical research history, why did Marci have to halt her seminal tDCS study?
What is misplaced the leads/electrodes?
This questionnaire measures subclinical inability to identify and describe emotions experienced by one's self.
