I think it was Gibson and Walk who developped an apparatus called the visual cliff (but don't quote me on this).Anyway,the visual cliff was a big table like apparatus covered with glass and one section could be perceived as shallow and the opposite section was constructed to give fhe perception of a deep precipice. Toddlers were placed on the shallow side and had to cross over to the deep side to get to the awaiting arms of their moms.It was my understanding that the apparatus was designed to affirm that depth perception was innate.I remember seeing a visual of this and some of the toddlers were crying and failed to cross over even though their moms encouraged them to cross the glass surface. In retrospect were there any ethical concerns about that type of research using toddlers? How does this measure up to the L'il Albert experiment re the impact on the emotional life on toddlers? Has this experiment ever been replicated?( I understand that other paradigms have used others animals like goats and other ruminants) Just as we would not dare do a L.il Albert or a Jabe Elliot (brown eyes, blue eyes),would repeating a visual cliff today could be construed as toddler cruelty? Send me something.
