The thesis investigates ways of communicating gratitude are perceived and realised in Jordan and England. It focuses on the impact of several variables on the expression of gratitude and examines the differences between the data elicited by pragmatic research instruments (DCT and role-play). Data were collected from native speakers: 46 Jordanian Arabic, 46 English natives using DCTs, role-plays and interviews. Slight similarities and significant cross-cultural differences were revealed in terms of gratitude expressions’ perception, number and strategy type. This cultural contrast reveals differences in the sociolinguistic patterns of conveying gratitude in verbal and nonverbal communication. The most important theoretical finding is that the data, while consistent with many views found in the existing literature, do not support Brown and Levinson’s (1987) claim that communicating gratitude intrinsically threatens the speaker’s negative face. Rather, it is argued that gratitude should be viewed as a means of establishing and sustaining social relationships. The findings suggest that cultural variation in expressing gratitude is due to the high degree of sensitivity to the interplay of several social and contextual variables. The findings provide worthwhile insights into theoretical issues concerning the nature of communicative acts, the relation between types of communicative acts and the general principles of human communication, especially rapport between people in social interaction, as well as the relation between culture-specific and universal features of communicative activity types. Differences were found between pragmatic research instruments. The outcomes indicate that using a mixture of methods is preferable as long as this serves the aim of the study as it merges their advantages by eliciting spontaneous data in controlled settings. The ramifications of this study for future multi-dimensional investigations of the contrasts between Arabic and English speaking cultures are expected to prove particularly significant in virtue of corroborating or refuting existing findings and in this way paving the way for new research.

<p> While much scholarly attention has been given to the benefits of expressing gratitude, a paucity of research exists in the competent communication of gratitude. The current dissertation employs three studies to ascertain qualities of gratitude communication that are favored in message recipients, establish criteria for competent gratitude communication, and identify the extent to which features of gratitude messages corresponds to the competency criteria. The first study investigated various aspects of gratitude communication that message recipients characterized as ideal, such as verbal, nonverbal, and contextual factors. Building upon these findings, Study 2 developed and validated two scales: one measuring benefactor perceptions of the extent to which gratitude messages convey meaningful impact, thoughtfulness, and sincerity (the gratitude assessment scale, or GAS); and another measuring the presence of salient features of explicitness, elaboration, and affirmation in gratitude messages (the gratitude message features, or GMF, scale). Finally, participants in Study 3 were randomly exposed to a hypothetical gratitude message that contained one of the three features, all three features, or none of the features and responded to the GAS to evaluate their perceptions of the message. Findings established the skills-competence link, in which explicitness, elaboration, and affirmation all predict benefactor perceptions of the message’s meaningful impact, thoughtfulness, and sincerity. The findings of the dissertation reveal four significant contributions to gratitude communication research: (1) the identification of salient message features and benefactor evaluations of the message that reflect competent gratitude communication, (2) the development of statistically sound instrumentation pertaining to gratitude communication competence, (3) the establishment of the skills-competence link, which associates the features of a gratitude message to message perceptions that are essential to gratitude communication, and (4) the beginnings of a model of the process of gratitude communication.  </p>
