This thesis primarily deals with two concepts in painting that I explored during my Graduate studies at the University of New Orleans. Both concepts are similar in execution but have two distinctly different results.

This thesis explores the functions of laughter in Japanese communication. In orientation it contrasts markedly with previous studies and is the first study to have been based on such a large volume of data. In this paper I have focused on laughter as it serves to maintain a co-operative relationship between the participants in a conversation. I find that in the process of communication, people necessarily have to lay themselves open to others, and in doing so they become conscious of the barrier surrounding and protecting their field, i.e. their �inner world�. I hypothesise that in Japanese at least it is consciousness of this barrier that causes the occurrence of laughter in discourse. In other words, people laugh as part of the process of opening up to others, and also to show their intention to be co-operative. By laughing, people are either confirming that they belong to the same in-group, or they are pretending to belong to the same in-group in order to show co-operation. In my model, laughter is classified: A: Joyful laughter for identifying with the in-group B: Balancing laughter for easing tension C: Laughter as a cover-up. A is also divided into 3 subcategories, B into 3, and C into 2 according to the subject of the utterance and the direction of movement into the protective barrier. Two types of statistical analysis were applied to the data in order to the test the validity of the classification. Keywords: interpersonal communication; laughter; field; barrier; co-operation; joy; balancing; cover-up gender
