    The effects of source credibility in the presence or absence of prior attitudes: Implications for the design of persuasive communication campaigns
    (Wiley, 2010) Albarracin, Dolores; Seignourel, Paul J.; N/A; Kumkale, Gökçe Tarcan; PhD Student; Graduate School of Social Sciences and Humanities; 105011
    Most theories of persuasion predict that limited ability and motivation to think about communications should increase the impact of source credibility on persuasion. Furthermore, this effect is assumed to occur, regardless of whether or not the recipients have prior attitudes. In this study, the effects of source credibility, ability, and motivation (knowledge, message repetition, relevance) on persuasion were examined meta-analytically across both attitude formation and change conditions. Findings revealed that the Source Credibility x Ability/Motivation interaction emerged only when participants lacked prior attitudes and were unable to form a new attitude based on the message content. In such settings, the effects of source credibility decayed rapidly. The implications of these findings for applied communication campaigns are discussed.

    Who does not get screened? a simple model of the complex relationships in mammogram non-attendance
    (Sage Publications Ltd, 2016) N/A; N/A; Şen, Celile Katrine Naivar; Kumkale, Gökçe Tarcan; PhD Student; PhD Student; Graduate School of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; N/A; 105011
    With increasing mammogram rates, identifying attributes of non-attending women entails going beyond differences in demographic groups to reveal complex interactions among personality attributes. In this study, we analyzed survey data from 474 women aged 41 years and older using decision trees. By incorporating personality, religiousness, and age, we were able to correctly classify 42.9 percent of non-attenders compared to 4.4 percent with logistic regression analysis. Our findings suggest that incorporating personality and religiousness attributes may increase non-attender identification. Furthermore, the simple profile generated by decision trees provides a clear map useful for intervention planning.

    Individual differences in willingness to become an organ donor: a decision tree approach to reasoned action
    (Pergamon-Elsevier Science Ltd, 2013) N/A; N/A; Demir, Başar; Kumkale, Gökçe Tarcan; N/A; PhD Student; N/A; Graduate School of Social Sciences and Humanities; N/A; 105011
    The promotion of organ donation requires a better understanding of the attributes associated with willingness to donate. This entails revealing complex interactions among personality attributes related to intentions and behaviors. In the present study, survey data from young adults (N = 367) were analyzed using decision tree algorithms to identify these interactions within the reasoned action framework. Within this structure, donation attitudes, intentions, and behaviors were examined in relation to individual differences such as conscientiousness, empathy, time orientation, religiosity, and interpersonal trust.

    When the expectations from a message will not be realized: Naive theories can eliminate expectation-congruent judgments via correction
    (Elsevier, 2009) Handley, Ian M.; Albarracin, Dolores; Brown, Rick D.; Li, Hong; Kumkale, Ece C.; N/A; Kumkale, Gökçe Tarcan; PhD Student; Graduate School of Social Sciences and Humanities; 105011
    Research typically reveals that individuals like an object more when a persuasive message convinces them that this object is pleasant. In this paper, two experiments were conducted to understand the influence of such message-induced affective-expectations on judgments of experienced affect following direct encounter with an alcohol type of drink. As predicted, before trying the drink, recipients of the positive expectation message had more positive expectations than recipients of the negative-expectation message. After drinking, participants judged the beverage to elicit affect congruent with message-induced expectations to the extent they did not endorse a naive theory that their affective expectations congruently influence their experienced affect. In contrast, after drinking, the effect of the message disappeared when participants did endorse this naive theory. Moderation of these effects, as well as theoretical and practical implications, are addressed.
