​Overview. In a opportunity trial conducted in a men's lavatory at a Midwestern U.S. university, themes were assigned to one of three flattens of interpersonal remoteness. Men who entered a three-urinal lavatory to urinate were inexplicable to use the leftmost urinal. A allied was placed straightway neighboring to the theme, one urinal removed, or was listless from the lavatory. An witness stationed in a toilet stall timed the stay and permanence of micturation.

Subjects. Data were collected on 60 users of the men's lavatory. A user was included as a theme if no other user, to-boot the allied, was introduce during his urination. If someone else was introduce or entered during urination, the user was not counted. Conditions were assigned and skilful precedently the themeed entered the lavatory. Subjects were not apprised that they had participated in an experiment.

Procedure. The observed lavatory was harmonious off a main hallway, neighboring to a bulky classroom. The observed use admonish averaged encircling one peculiar entire 6 minutes. The restroom contained two toilet stalls and three urinals. The urinals were 18 inches distant after a while 18 inches of tile among neighboring urinals and deferred up from the bottom encircling 4 feet. The urinals were automatically blushing at 10-minute intervals.

The themes were inexplicable to use the leftmost urinal under one of three flattens of interpersonal remoteness. In the hinder remoteness situation, a allied visible to urinate was stationed at the average urinal, and a "don't use, washing urinal" token accompanied by a bucket of introduce and a defend was placed on the lawfulmost urinal. This course left a remoteness of closely 16 to 18 inches among the shoulders of the theme and allied. In the sober remoteness situation, the allied incident at the lawfulmost urinal and the bucket and token were placed in the average urinal. This course left a remoteness of 52 to 54 inches among the theme and allied. In a regulate situation, the allied was not introduce in the lavatory and twain the average and lawful urinals had tokens on them after a while the introduce bucket in among. 

An witness was stationed in the toilet stall straightway neighboring to the themes' urinal. During trodden tests of these procedures it became lucid that inclineers cues could not be used to tokenal the collation and halt of micuration. The urinals were so silent that uniform the allied lasting neighboring to the theme could not incline the urine striking the urinal. Instead, visual cues were used. The witness used a periscope prism imbedded in a stack of books false on the bottom of the toilet stall. An 11 inch immeasurableness among the bottom and the glacis of the toilet stall supposing a intention, through the periscope, of the user's inferior torso and made feasible trodden visual sightings of the tendency of urine. The witness, at-last, was incompetent to see a theme's countenance. The witness working two plug watches when a theme gross up the urinal, plugped one when urination began, and plugped the other when urination was terminated. These times recognized regard of the two trusting variables: stay of aggression and permanence of micturation. 

1.​What were two flaws in the overall contrivance?
