Marcos Alberti's "Three Glasses After" series (Links to an external site.)Links to an external site.captures several of his friends after a day at work, then again after one, two and three glasses of vino. The result? A transition from self-conscious and straight-laced to carefree.
"There is a saying about wine that I really like and it's something like this: 'The first glass of wine is all about the food, the second glass is about love and the third glass is about mayhem'," Alberti said. "I really wanted to see it for myself if that affirmation was in fact true."
The project, which Alberti said "started as a joke", shows the subject shortly after arriving at his studio, "to capture the stress and the fatigue after a full day". The Brazilian then snapped a simple portrait after each glass to document their change.
"People from all walks of life - music, art, fashion, dance, architecture, advertising - got together for a couple of nights, and by the end of the third glass several smiles emerged and many stories were told," he said.
Alberti wanted to show that, despite its obvious dangers, alcohol can have its benefits when consumed in moderation. "I only saw bad things about alcohol, so I wanted to show that, in a good and happy environment, with friends and with moderation, alcohol can be a good thing," he told i100. "It brings people together."
And judging by the wide beams and energetic laughs most of his subjects sport in their final picture, Alberti isn't wrong.

QUESTION:
PART 1:
Alberti is claiming a causal relationship between drinking wine and a reduction in stress. He is presenting a series of photographs as evidence. What is the big difference between what Alberti has done and a randomized controlled experiment? SELECT ONE....will it be 1,2,3, or 4?
4. He does not have a hypothesis.
PART 2:
a. Generate one specific plausible alternate explanation for the change in the facial expressions of the people in Alberti's photographs.
b. How would you test the alternative explanation you proposed in part a?
Explanation / Answer
According to me, it would be option 2. The groups aren't equal to being with. What is lacking in his study is the fact that he has taken people from all walks of life, but the inclusion exclusion criteria is flawed.
He has only taken people from a higher socio economic status, the so called elite and bourgeoisie crowd as his sample. These people and their mannerisms after three glasses of wine would probably be inherently different from those with a lower socio economic status.
Part2
One plausible confounding varibale for Alberti , and a potential explanation for the evident change in facial expression could be owing to the fact that over the continuuum and period of sharing of three glasses, the time lapse itself would be owing to the warming up of the people to the given social group, and aiding in the assuaging of social inhibitions if any to begin with.
It could also be the fact that, Alberti without any prior assessment of the people, and by not having two separate groups: control and experiment, has not realized that he has probably chosen people who display extraversion as a strong personality characteristic.
b. by having a prior personalty assessment too, and segregating the groups into two: control and experiment, a conclusion of considerable reliability and validity.
