Key Ideas
Mirror Exposure Effect
The mirror exposure effect is a psychological phenomenon where individuals tend to develop a preference for stimuli that they have been repeatedly exposed to over time. Essentially, the more exposure individuals have to a particular stimulus, the more they tend to like it, even if they were initially neutral or indifferent toward it.
Here's how the mirror exposure effect relates to persuasion:
Increased Familiarity: Repeated exposure to a message, product, or idea can lead to increased familiarity with it. As individuals become more familiar with the stimulus through repeated exposure, they may develop a sense of comfort and ease with it, which can influence their attitudes and preferences.
Enhanced Liking: The mirror exposure effect suggests that familiarity breeds liking. As individuals are exposed to a stimulus more frequently, they are more likely to develop positive feelings toward it. This can be particularly useful in persuasion, as increasing individuals' liking for a product, idea, or message can make them more receptive to it.
Reduced Uncertainty: Exposure to a stimulus can also reduce uncertainty and ambiguity surrounding it. When individuals encounter a message or idea multiple times, they may gain a better understanding of it and feel more confident in their opinions or beliefs about it. This reduced uncertainty can contribute to greater persuasion effectiveness.
Mere Exposure Effect: The mirror exposure effect is related to the broader concept of the mere exposure effect, which suggests that mere exposure to a stimulus can lead to increased liking for it. The more individuals are exposed to a stimulus, the more positively they tend to evaluate it. This effect has been observed across various domains, including consumer behavior, advertising, and interpersonal attraction.
In summary, the mirror exposure effect highlights the power of repeated exposure in shaping individuals' attitudes and preferences. In persuasion, leveraging this effect involves strategically exposing individuals to a message, product, or idea multiple times to increase their familiarity with it and enhance their liking and acceptance. By capitalizing on the mirror exposure effect, persuaders can increase the effectiveness of their persuasion efforts and influence individuals' attitudes and behaviors more effectively.
Example Studies
Several experiments have demonstrated the mirror exposure effect, providing evidence for the phenomenon across various domains. Here are some notable studies:
Zajonc's Chinese Character Study (1968): In one of the classic experiments demonstrating the mirror exposure effect, psychologist Robert Zajonc presented participants with novel Chinese characters and asked them to rate their liking for each character. Participants were exposed to some characters multiple times while others were presented only once. The results showed that participants rated the characters they had been exposed to more favorably, even when they were not consciously aware of the repetitions. This study provided foundational evidence for the mere exposure effect, including the mirror exposure effect.
Bornstein's Artwork Study (1989): In a study by Daniel Bornstein, participants were repeatedly exposed to abstract artworks of varying complexity. Over several exposure sessions, participants rated their liking for each artwork. The results revealed that participants' liking for the artworks increased with each exposure, demonstrating the mirror exposure effect. Importantly, this effect was observed even when participants were not consciously aware of the repetitions.
Monahan and Murphy's Word List Study (1971): In this study, participants were presented with lists of words, with some words repeated multiple times and others presented only once. Afterward, participants were asked to rate their liking for each word. The results showed that participants rated the repeated words more favorably than the non-repeated words, providing further evidence for the mirror exposure effect.
Berlyne's Stimulus Complexity Study (1970): In a study by D. E. Berlyne, participants were exposed to a series of visual stimuli varying in complexity. After repeated exposures, participants rated their liking for each stimulus. The results showed that participants consistently rated the more complex stimuli higher in liking, indicating that familiarity and exposure influenced their preferences.
Moreland and Beach's Female Names Study (1992): In this study, participants were repeatedly exposed to lists of female names varying in frequency of exposure. Afterward, participants were asked to rate their liking for each name. The results showed that participants rated the more frequently exposed names more favorably, demonstrating the mirror exposure effect in the context of social stimuli.
These studies provide empirical support for the mirror exposure effect, showing that repeated exposure to stimuli can lead to increased liking and preference for those stimuli. The findings have important implications for understanding human preferences, attitudes, and behavior, as well as for informing persuasion and marketing strategies.
Processing Fluency
Processing fluency refers to the ease and efficiency with which information is processed by the mind. When information is presented in a way that is easy to understand, recognize, and remember, it is said to be processed fluently. This concept is closely related to habituating a message and persuasion in several ways:
Repetition and Familiarity: Habituation involves repeated exposure to a message, which can increase familiarity with the information. As individuals become more familiar with the message through repetition, they experience greater processing fluency when encountering it. Familiarity with the message makes it easier for individuals to process and comprehend, leading to increased persuasion effectiveness.
Ease of Processing: Messages that are presented in a fluent manner are easier for individuals to process mentally. This ease of processing can enhance the persuasiveness of the message by reducing cognitive effort and increasing receptivity. When individuals encounter a familiar message that is presented fluently, they are more likely to accept and be influenced by its content.
Positive Affect: Processing fluency is associated with positive affective responses, such as feelings of comfort, familiarity, and liking. When individuals experience fluent processing of a message, they may also experience positive emotions toward the message and its content. This positive affect can contribute to increased persuasion by enhancing individuals' attitudes and receptivity to the message.
Perceived Truthfulness and Credibility: Fluent processing of a message can lead individuals to perceive it as more truthful and credible. Messages that are presented clearly and comprehensibly are more likely to be perceived as accurate and trustworthy. As a result, messages that are habituated through repetition and processed fluently may have greater persuasive impact due to their perceived credibility.
Memory Encoding and Retrieval: Messages that are processed fluently are more likely to be encoded into memory and retrieved later when relevant. Habituation of a message increases its accessibility in memory, making it more likely to influence individuals' attitudes and behaviors over time. The fluency with which the message is processed during encoding and retrieval contributes to its persuasive influence.
In summary, processing fluency plays a crucial role in the effectiveness of habituating a message and persuasion. Messages that are presented fluently are easier to process, leading to increased familiarity, positive affect, perceived credibility, and memory retention. By leveraging processing fluency through repetition and clear presentation, persuaders can enhance the persuasive impact of their messages and increase their likelihood of influencing attitudes and behaviors.
Example Studies
Several experiments have investigated the effect of processing fluency on various cognitive processes, including perception, judgment, decision-making, and persuasion. Here are some notable studies that demonstrate the influence of processing fluency:
Jacoby and Dallas's Word Fragment Study (1981): In this classic study, participants were presented with a list of words, some of which were presented in a clear font and others in a distorted font that made them difficult to read. Participants were then asked to complete word fragments based on the previously presented words. The results showed that participants were more likely to complete the word fragments with words that were presented in a clear font, demonstrating that fluently processed information is more easily accessible in memory.
Whittlesea and Williams's Lexical Decision Task Study (2001): In this study, participants were presented with pairs of letter strings and asked to indicate whether each pair formed a word or a non-word. Some pairs contained words that were presented multiple times, while others contained new words. The results showed that participants were faster and more accurate at identifying repeated words as real words compared to new words, indicating that repeated exposure increased processing fluency and facilitated word recognition.
Oppenheimer's Font Study (2008): In this study, participants were presented with statements printed in either an easy-to-read font or a difficult-to-read font. Participants rated the statements in terms of their truthfulness. The results showed that statements presented in an easy-to-read font were rated as more truthful than those presented in a difficult-to-read font, demonstrating that processing fluency influenced participants' judgments of truthfulness.
Song and Schwarz's Rhyme Judgment Study (2008): In this experiment, participants were presented with pairs of statements that either rhymed or did not rhyme. Some pairs were presented in a clear font, while others were presented in a difficult-to-read font. Participants were asked to judge whether each pair rhymed or not. The results showed that participants were more likely to judge rhyming pairs as rhyming when presented in a clear font compared to a difficult-to-read font, indicating that processing fluency influenced their judgments.
Alter and Oppenheimer's Fluency of Processing Study (2006): In this study, participants were presented with statements printed in either an easy-to-read font or a difficult-to-read font. Participants rated their agreement with each statement. The results showed that statements presented in an easy-to-read font were rated as more agreeable than those presented in a difficult-to-read font, suggesting that processing fluency influenced participants' attitudes and evaluations.
These studies provide empirical evidence for the role of processing fluency in various cognitive processes, including perception, judgment, decision-making, and persuasion. The findings highlight the importance of fluently processed information in shaping individuals' attitudes, beliefs, and behaviors.
Assertiveness Experiment
The assertiveness experiment was conducted by Wilson and Schooler (1991). In this study, participants were asked to generate either 6 or 12 examples of times when they had been assertive in their lives.
The results of the experiment demonstrated an intriguing effect related to processing fluency and attitude change. Participants who were asked to generate 12 examples rated themselves as less assertive afterward compared to those who were asked to generate only 6 examples.
This effect occurred because generating a larger number of examples required more cognitive effort and resulted in greater fluency of thought about their assertiveness. As a result, participants in the 12-example condition became more aware of instances where they may not have been as assertive as they initially thought, leading to a change in their self-perception.
This study illustrates how the fluency of thought and cognitive effort involved in generating examples can influence individuals' attitudes and self-perceptions. It highlights the role of processing fluency in shaping judgments and attitudes, even in tasks as seemingly straightforward as recalling instances of assertiveness.
