Episode 16: Personal Space Invasion: What Happens When Someone Invades Your Personal Space?

Do feel slightly uncomfortable in the bathroom? How does the presence of others in the bathroom affect you? What about places other than the bathroom? How close is too close? A psychological study was done in 1976 in which psychology researchers hid in men’s bathrooms to observe…well, you’ll find out. Learn more about personal space in this episode of The Psych Files.

    As a sufferer of paruresis myself I found it interesting to know that “normal” persons have some hesitancy and reduction of voiding under situations of reduced personal space.

    Not having any specific event or series of events that I can point to that may have lead to my condition I can only assume that it began as subtle self consciousness of the time taken to begin urinating.

    I would be interested to know if any of the 60 participants failed to void.

    My friends tend to call shy bladder syndrome “stage fright”.
    Regarding the term “micturition” I first came across it in the book “The Hitchhiker’s Guide to the Galaxy” where an example of Vogon poetry (the third worst poetry in the universe) is given as
    Oh freddled gruntbuggly, Thy micturations [sic]are to me As plurdled gabbleblotchits On a lurgid bee
    So Douglas Adams and psychologists have at least one thing in common.

    I don’t remember that line but I’ll take your word on it. I read the Hitchhiker’s Guide quite some time ago. Great book (bad movie though).
