This mixed methods study deepens scholarly understandings of laughter as both a communicative act and a form of affection by investigating how friends in dyadic interactions make meaning of the laughter they share during those interactions. Pairs of friends were video-recorded having a short, light-hearted conversation. Following the conversation, each individual watched the video, explaining at each instance of laughter what they were feeling and why they believed laughter occurred at that point in the conversation. Data from both interactants was then compared to examine the types of laughter that were manifested in conversations as well as patterns regarding participants' perceptions and communication of laughter. In general, previous laughter categories were supported by the data, but new categories were also identified, including laughing out of relatability (show understanding), lighten (decrease stress or negative feelings), memory (remember the situation being discussed), reactionary (because the other person laughed first), anticipation (expecting something funny to happen), cue (indicate that the other person should laugh), common joke (previously shared and recognized humor), mental image (picturing the event or story), and endearing (out of love) laughter. A new categorization system is proposed which assesses laughter in terms of its relational effects along the spectrums of prosocial-antisocial and basic-complex; in particular, prosocial laughter is examined as an affectionate behavior according to the definitions from Floyd's Affection Exchange Theory. This study offers a deeper understanding of laughter as a crucial yet understudied form of nonverbal communication by highlighting the relational meanings and implications of laughter among friends.born digitalmasters thesesengCopyright and other restrictions may apply.
