A field experiment was conducted in which a single male, a single female, or a male-female couple attempted to hitch rides at four different traffic locations, under conditions in which the hitchhikers either stared at or looked away from oncoming drivers...
In the stare conditions, E stared at the driver of the target vehicle and attempted to fixate on the driver's gaze and maintain this gaze as long as possible until the driver either stopped his vehicle or drove on. In the comparison conditions, E looked anywhere else but at the driver. Thus, on some trials E looked in the general direction of the car; on other trials E looked at his feet, the road, the sky, etc. Es were specifically instructed to neither smile nor frown, and to maintain a casual (neither rigid nor slouching) body postural orientation while soliciting rides.

it seems that the effect of attempted eye contact and sex of hitchhikers were such that a staring female got the most rides and a nonstaring male the least, with a staring male and a nonstaring female in between.

Contrary to popular belief and hitchhiking folklore , it was no easier for a male-female couple to hitch a ride than a single male, and a mixed sex couple was less successful at soliciting rides than a single female hitchhiker. Although the generality of this conclusion is limited by the fact that it is based upon results obtained by one male and one female E, it is probably the case that couples are less successful hitching rides because of space limitations in the cars they approach. That is, it is more likely that the driver will have room for one additional passenger than that he will have room for two or more additional passengers in his car.

ads for a product called Vivarin told women their husbands would be more attracted to them if they used it, apparently implying some sort of sexually based arousal which would renew the lagging instincts of tired old married folks. To quote the ad directly:

"One day it dawned on me that I was boring my husband to death. It was hard for me to admit it—but it was true…. Often by the time he came home at night I was feeling dull, tired and drowsy, and so Jim would look at television and, for the most part, act like I wasn’t even there. And I wasn’t. I decided that I had to do something. I had seen an advertisement for a tablet called Vivarin. It said that Vivarin was a non-habit forming stimulant tablet that would give me a quick lift. Last week… I took a Vivarin tablet… just about an hour before Jim came home, and I found time to pretty up a little, too. It worked. All of a sudden Jim was coming home to a more exciting woman, me… The other day—it wasn’t even my birthday—Jim sent me flowers with a note. The note began: ‘To my new wife…'"

All very nice, but but the contribution of Vivarin was to provide merely the amount of caffeine found in two cups of coffee. No miracle aphrodisiac, just good old caffeine at a premium price!
The major allegation of the FTC's complaint about Vivarin concerned this social-psychological misrepresentation... But the Vivarin ads were also alleged to be deceptive because they did not disclose caffeine to be the critical ingredient.

Siano and Piazza have high hopes for their Tarottells Machine, an invention that so excites Vinnie, the spokesman, that he likes to take off his jacket and stand as he describes it.

Siano, an artist at Grumman Aircraft and a textbook illustrator, rises to lyrical heights demonstrating his machine: "This is the first time in the history of the world — the first Tarot machine. Automation has come to Tarot..."

The machine, with cursor and compass, has a custom carrying case. The game is made of black plastic and bright orange Tarot cards and measures some 27 inches square.

You get the cards' message by pressing a lever to cut the cards three times to the left — mandatory procedure in Tarot. Then they spin around until another lever activates a silver pointer that singles out the card.

"We have also incorporated astrology to get the best possible reading," says Siano, whipping out a tray of beautifully drawn figures of the Zodiac. "And we have also adopted ESP into this machine.

"You'll get a better answer from this than any Ouija Board. What we need is a dynamic corporation that has the guts to turn this thing out."

Siano says a big toy manufacturer had the machine in its vaults for six weeks, but the man who thought it a good idea was fired and the machine was returned.
