Savage-Rumbaugh (4)

The Outdoor Environment: The outdoor environment was 55 acre forest complex. Food was placed in 17 different locations in the warmer months. Kanzi and Mulika would collect the food from different places. Kanzi and Mulika's recorded their responses by using the laminated pointing board and the researchers recorded by hand at the end of each day. Austin and Sherman couldn't have their responses recorded outdoors because the common chimps couldn't use the pointing board as their hand movements weren't specific enough. A blind test was conducted with an experimenter, who'd never been in the woods. Kanzi was able to lead the the experimenter around the 55 acre outdoor environment by correctly using the lexigram.Indoor Envrionment: During the day Kanzi and Mulika helped in a variety of domestic activities such as doing the laundry. They had access to games and TV, and they had lots of human interaction. The data inside was recorded the computer automatically recorded their responses indoors. This meant that there is a complete record of Kanzi's utterances between the ages of 30-47 months of age and for Mulika 11-21 months. Each utterance was classified when it occured; firstly it was classified as correct or incorrect. Secondly, it was recorded as spontaneous, imitated or structured.Testing Language Abilities: The criteria used for determining whether a word should be listed as part of Kanzi's and Mulika's vocab was that the utterance was made in a spontaneous situation. e.g. Kanzi indicated he wanted to go to the tree-house and this would be verified if he took the researcher to that location, producing a positive concordance score. For a symbol to be classified as being part of Kanzi and Mulika's vocab it had to occur spontaneously 9/10 occasions followed by a behavioural concordance of 9/10 additional occurences.
