概要
Coffee has been found to have beneficial effects on cognitive function and blood sugar control. Benefits include reduced risk of cognitive decline and improved performance on cognitive tests, as well as reduced risk of diabetes and improved blood sugar control in people with diabetes, a population that is at a higher risk of cognitive decline. These effects have been observed for both caffeinated and decaffeinated co...もっと見る
詳細説明
Following recruitment, interested participants will undertake an online screening session with the experimenter to check the inclusion and exclusion criteria (see section 3). Following this, study procedures will be explained in full by the experimenter and the participants will receive the information sheet (by email) and complete the consent form online. At this point, demographic information and chronic mood measu...もっと見る

|---|---|---|
Short term Memory | The Rey Auditory Verbal Learning Test (RAVLT) will present two lists of 15 words each, which will be played via audio recording after which participants will be asked to recite as many words as they can remember. | 0 hours |
Short term Memory | The Digit Span Forward Task will show a series of numbers in a specific order which participants will be asked to type out in the order shown | 0 hours |
Short term Memory | The Corsi Block Tapping task will present participants with a screen of blocks that light up in a sequence which participants will have to remember and tap the blocks in the order shown; the sequence lengthens or shortens based on participants performance. | 0 hours |
Processing Speed | A computerised version of the Digit Symbol Substitution Test (DSST) will be used to assess processing speed. Participants will be given a legend with numbers corresponding to symbols, then presented with a specific pair of number/symbol. They will then determine if that pair is a match or a mismatch, and respond accordingly. They will be measured for speed and accuracy. | 0 hours |

Source Monitoring | Source monitoring will be assessed using a modified version of the Rey Auditory Verbal Learning Test (RAVLT) where a third "distractor" list will be presented, after which participants will be asked to recognize if a word is one heard in the original two lists, or a new word. If participants respond the former, they will then be asked to identify which list they heard the word from. | 0 hours |

Mood | Positive affect will be measured using the Positive and Negative Affect Schedule (PANAS). The ratings (a scale of 1-5) for the 10 positive items will be summed to get a Positive Affect (PA) score. Scores can range from 10 to 50, with higher scores indicated higher levels of PA | 0 hours |
Mood | Negative affect will be measured using the Positive and Negative Affect Schedule (PANAS). The ratings (a scale of 1-5) for the 10 negative items will be summed to get a Negative Affect (NA) score. Scores can range from 10 to 50, with higher scores indicated higher levels of PA | 0 hours |
Mood | Mood will be measured using the Bond-Lader Visual Analogue Scale (BL-VAS) where participants rate their mood by marking a continuous line between two extreme endpoints, typically ranging from "not at all" to "extremely." The values are averaged into three categories (alertness, contentedness, and calmness) and higher scores indicate higher experiencing of each category. | 0 hours |
Mood | Mood will be measured using the Immediate Mood Scaler (IMS), which captures current mood states using 7-point Likert scales. The total score is calculated by summing all 22 items, with higher scores indicating more negative mood states | 0 hours |
