We carried out a 'Functional Test' for Leonhart High Caffeine Hot Chocolate to see the practical effects on concentration and anxiety
Actual implementation
Number of participants: 19 registered, 1 drop-out, 16 eligible dataset
8:30 – 9:00: Participants registered for the study. Info collected:
Demographic (age, gender)
Stimulant-consuming habit (coffee, cigarettes, alcohol)
Health conditions (menstruation, medical – neurological – psychiatric disorders, family’s psychiatric history)
Stress level
9:00 – 9:30 & 10:30 – 11:00:
Participants perform the cognitive-function games online, before and after consumption.
|
Name of Game |
Cognitive function being tested |
How to play |
Data collected (that are useful for analysis) |
|
N-Back task |
Memory, attention |
Participants must tap the screen when the 2-letter-ago appears (e.g. A – M – A ) |
Trial type, score (only count right answer), match, miss, false alarm, reaction time |
|
Sustained Attention to Response Task |
Attention, information process |
Participants must tap the screen when numbers appear. Except for number 3 |
Trial type, score, reaction time |
|
Wisconsin Card Sorting Inspired Task |
Reasoning, information process |
Participants must match the card with 1 of 4 given cards, by either shape – color – number. The participant must figure out the matching rule. |
Reaction time, score |
9:30 – 10:30: participants taste the product and give feedbacks on taste/aroma. All participants take Leonhart sample – with the same ratio of Caffeine and Ashwagandha.
Data collected:
Taste and aroma preference
Analysis – register survey
Demographic info of participants
Stress level of participants
Coffee usage frequency of participants
Tobacco usage frequency of participants
Alcohol usage frequency of participants
Health conditions
In terms of health conditions, no participants are under any medical, neurological, psychiatric conditions, or having family members being treated for these conditions
Analysis – Cognitive game results - Nback
Game 1: N-Back task
Q1: Did the overall accuracy and memory improve after taking Leonhart (demonstrated by % of total score)?
Q2: Did the nervousness reduce after taking Leonhart, demonstrated by increase in % of correct matches and reduction of % false alarm click?
-> relatively the same, no impacts
Q3: Did the alertness and focus increase after taking Leonhart, demonstrated by a decrease in reaction time?
Q4: Did the memory and accuracy increase, demonstrated by reducing reaction time of correct matches?
Game 2: SART
Q1: Did the overall attention and information processing improve after taking Leonhart (demonstrated by % of total score)?
Q2: Did information processing increase after taking Leonhart, demonstrated by a decrease in reaction time?
Q3: Did alertness increase after taking Leonhart, demonstrated by a decrease in reaction time of Go trials (trials that the participants were allowed to press the button)?
Game 3: WCST
Q1: Did the overall logical processing improve after taking Leonhart (demonstrated by % of total score)?
Q2: Did the logical processing speed improve after taking Leonhart, demonstrated by an decrease of reaction time of correct matches?
Q3: Did the logical processing speed improve after taking Leonhart, demonstrated by an decrease of reaction time to find the next card-matching rule when the rule is switched?
Q4: Did the logical processing improve after taking Leonhart, demonstrated by an decrease of wrong match and time-out?
