When Self Is the Source: Effects of Media Customization on Message Processing

Customization of media technologies enables users to become active sources in the communication process. But, does this sense of “self-as-source” alter the way users process information received via customized interfaces? A between-subjects experiment (N = 146) was conducted to answer this question. Data indicate that the effect of self-driven customization (high vs. low self-as-source) on persuasive message processing is mediated by perceived identity. Those who experience high self-as-source tend to process messages less systematically, but perceive the message topic as more important and show greater intention to follow the suggestions of messages than those with a low sense of self-as-source, an effect that is mediated by perceived identity. Theoretical implications for persuasive technologies, dual process models, and the agency model of customization are discussed, followed by practical implications for communicators who wish to incorporate new media technologies into their social influence campaigns.     

A note on monotonicity of item response functions for ordered polytomous item response theory models

A monotone relationship between a true score (τ) and a latent trait level (θ) has been a key assumption for many psychometric applications. The monotonicity property in dichotomous response models is evident as a result of a transformation via a test characteristic curve. Monotonicity in polytomous models, in contrast, is not immediately obvious because item response functions are determined by a set of response category curves, which are conceivably non-monotonic in θ. The purpose of the present note is to demonstrate strict monotonicity in ordered polytomous item response models. Five models that are widely used in operational assessments are considered for proof: the generalized partial credit model (Muraki, 1992, Applied Psychological Measurement, 16, 159), the nominal model (Bock, 1972, Psychometrika, 37, 29), the partial credit model (Masters, 1982, Psychometrika, 47, 147), the rating scale model (Andrich, 1978, Psychometrika, 43, 561), and the graded response model (Samejima, 1972, A general model for free-response data (Psychometric Monograph no. 18). Psychometric Society, Richmond). The study asserts that the item response functions in these models strictly increase in θ and thus there exists strict monotonicity between τ and θ under certain specified conditions. This conclusion validates the practice of customarily using τ in place of θ in applied settings and provides theoretical grounds for one-to-one transformations between the two scales.

Flattery will get you somewhere,sometimes? The effect of flattery and hotel segments on a hotel guests' green behavior

Considering the importance of the hotel guests' behavioral support for the hotels' green corporate social responsibility (CSR), this research examined the persuasive power of flattery in promoting guests' green behaviors. Study 1 revealed that a flattery message significantly increased the hotel guests' towel reuse intentions during their stay and this effect was mediated by their perceptions of the hotel's CSR motives. Study 2 further showed that a feeling of guilt served as another key mediator in the relationship between a flattery message and the guests' responses (i.e., perceived CSR motives, hotel image, attitudes toward a hotel, towel reuse intentions), which was moderated by hotel segment (economy vs. mid-priced vs. luxury). This research provides meaningful insights into the understanding of the consumers' pro-environmental decisions in the service consumption context and explains the underlying cognitive process. Moreover, this research offers an empirical message strategy by hotel segments to effectively promote the hotel guests' green behavior and achieve successful marketing outcomes.     

White lie-telling in children for politeness purposes

Prosocial lie-telling behavior in children between 3 and 11 years of age was examined using an undesirable gift paradigm. In the first condition, children received an undesirable gift and were questioned by the gift-giver about whether they liked the gift. In the second condition, children were also given an undesirable gift but received parental encouragement to tell a white lie prior to being questioned by the gift-giver. In the third condition, the child's parent received an undesirable gift and the child was encouraged to lie on behalf of their parent. In all conditions, the majority of children told a white lie and this tendency increased with age. Coding of children's facial expressions using Ekman and Friesen's (1978) Facial Action Coding System revealed significant but small differences between lie-tellers and control children in terms of both positive and negative facial expressions. Detailed parental instruction facilitated children's display of appropriate verbal and nonverbal expressive behaviors when they received an undesirable gift.

Cross-cultural differences in children's choices, categorizations, and evaluations of truths and lies

This study examined cross-cultural differences and similarities in children's moral understanding of individual- or collective-oriented lies and truths. Seven-, 9-, and 11-year-old Canadian and Chinese children were read stories about story characters facing moral dilemmas about whether to lie or tell the truth to help a group but harm an individual or vice versa. Participants chose to lie or to tell the truth as if they were the character (Experiments 1 and 2) and categorized and evaluated the story characters' truthful and untruthful statements (Experiments 3 and 4). Most children in both cultures labeled lies as lies and truths as truths. The major cultural differences lay in choices and moral evaluations. Chinese children chose lying to help a collective but harm an individual, and they rated it less negatively than lying with opposite consequences. Chinese children rated truth telling to help an individual but harm a group less positively than the alternative. Canadian children did the opposite. These findings suggest that cross-cultural differences in emphasis on groups versus individuals affect children's choices and moral judgments about truth and deception.

The Wick in the Candle of Learning: Epistemic Curiosity Activates Reward Circuitry and Enhances Memory

ABSTRACT— Curiosity has been described as a desire for learning and knowledge, but its underlying mechanisms are not well understood. We scanned subjects with functional magnetic resonance imaging while they read trivia questions. The level of curiosity when reading questions was correlated with activity in caudate regions previously suggested to be involved in anticipated reward. This finding led to a behavioral study, which showed that subjects spent more scarce resources (either limited tokens or waiting time) to find out answers when they were more curious. The functional imaging also showed that curiosity increased activity in memory areas when subjects guessed incorrectly, which suggests that curiosity may enhance memory for surprising new information. This prediction about memory enhancement was confirmed in a behavioral study: Higher curiosity in an initial session was correlated with better recall of surprising answers 1 to 2 weeks later.
