Accuracy in Detecting Potential Underage Drinkers: The Role of Contextual Effects in Proofing1

Three studies investigated the prevalence and influence of contextual effects in social judgments of age as they concern the purchase of alcohol. In Experiment 1, prior to rating a target individual, college students rated a series of photographs of persons considerably older or younger than the legal drinking age. Contrary to previous research on contrast effects, a cognitive assimilation effect was obtained for perceptions of age. Subjects rated a target person older when the prior stimuli were older, and younger when exposed to youthful stimuli. In Experiment 2, subjects again were exposed to older or younger stimuli or control stimuli (pictures of a university campus) and asked to rate a target individual. In an attempt to make salient the relevant perceptual category, subjects were asked specifically to make age ratings of the priming stimuli. Results again indicated an assimilation effect for age and the decision to proof. Attraction and liking data tended to demonstrate a contrast effect. Experiment 3 replicated the assimilation effects found in Experiments 1 and 2 using actual store clerks. These data are considered in light of the social factors that affect judgments in policies that seek to restrict access to alcohol among minors.     

Compared to what? Effects of categorization on hedonic contrast

Test stimuli are rated less “good” following very good context stimuli than when presented either alone or following neutral context stimuli. This diminution in rating is calledhedonic contrast. In two experiments, the degree of hedonic contrast depended on how subjects were instructed to categorize context and test stimuli. Contrast was substantially attenuated if context and test stimuli were said to belong to different categories. The effect was demonstrated for beverages (Experiment 1) and birds (Experiment 2). Stimuli’s hedonic ratings were far less affected by other stimuli declared to belong to a different category than by stimuli declared to belong to a common category.     

The categorization effect in hedonic contrast: Experts differ from novices

Test stimuli are rated as less “good” when they follow very good context stimuli than when they are presented alone. This diminution in rating is called hedonic contrast. Contrast is attenuated if the context and the test stimuli are perceived as being in different categories. Because experts use as their basic-level categories what are the subordinate levels for novices, they will categorize when novices do not. Therefore, in the following studies, both experts and novices showed hedonic contrast when attractive context orchids preceded more neutral test orchids. However, only the novices showed hedonic contrast when attractive context irises preceded the test orchids. Novices viewed the irises and the orchids as “flowers” and therefore members of the same category, resulting in contrast. Experts, however, viewed the irises and the orchids as being in different categories; therefore, hedonic contrast did not occur.     

It felt fluent but I did not like it: fluency effects in faces versus patterns

Whether you like a person or not is often appraised in a glance. However, under such short presentation durations stimuli are harder to perceive and, according to hedonic fluency theory-which holds that higher fluency is linked to higher liking-thus, are liked less. Given that liking considerably influences person perception, we tested how shorter and longer presentation durations affect liking for faces and compared this with abstract patterns. To capture facets of fluency of processing we assessed felt fluency, liking, and certainty ratings. Following predictions of fluency theory, longer presentation durations led to higher felt fluency, certainty, and positively affected liking judgments in the abstract patterns. In faces, felt fluency and certainty also increased with longer durations. However, with longer durations, faces were liked less, and liking was not related to felt fluency. In other words, in contrast to hedonic fluency theory, faces are more attractive when only seen for a short amount of time. Thus, fluency does not inevitably lead to more positive evaluations—it rather depends on the stimulus category. We discuss these findings in terms of the special status that faces have with regard to human perception and evaluation.     

Hedonic Tone,Perceived Arousal,and Item Desirability: Three Components of Self-reported Mood

Self-reports of mood are the most frequently used measure of subjective emotional experience in studies of human emotion. The present study evaluated the degree to which self-reports of mood reflect the social desirability of an affective state, rather than the hedonic tone and the level of arousal associated with such states. The study produced three main findings. First, the desirability of a mood and the hedonic quality of a mood are related, but not identical entities. Secondly, the desirability of a mood is also related to the level of arousal the mood denotes. Thirdly, desirability components are related to the self-report ratings of mood, but the ratings also reflect the hedonic tone and level of arousal describing the internal state of the respondents. Social desirability does affect the self-report ratings that are often used in emotion research, but such ratings also reflect something about the internal state of the respondents.     

Categorization reduces the effect of context on hedonic preference

When moderately hedonically positive test stimuli are presented following better-liked context stimuli, preferences between the test stimuli are reduced. This reduction in preference, hedonic condensation, occurs in settings that also produce negative hedonic contrast?the phenomenon in which moderately hedonically positive test stimuli seem less positive when they follow better-liked context stimuli. Subjects who were instructed that the context and test stimuli were from different categories exhibited less hedonic condensation. Those categories have smaller hedonic ranges than does the full stimulus set. The increase in preference magnitude with reduction in size of the hedonic range is predicted by Parducci’s (1995) range-frequency model.     

Ego involvement moderates the assimilation effect of affective expectations

Based on the affective expectations model and research on mental effort mobilization, two experiments manipulated affective expectations (no expectations versus positive expectations) and ego involvement (low versus high) and assessed participants’ affective reactions to hedonically neutral stimuli. In Experiment 1, evaluations were more positive when participants had positive expectations about neutral photos—but only when ego involvement was low. High ego involvement neutralized this affective expectation assimilation effect. Experiment 2 replicated these findings for experienced mood after reading a hedonically neutral short essay. Furthermore, high ego involvement led to longer response latencies in the affect ratings in Study 1. The findings support the idea that high ego involvement resulted in relatively high mental effort that was necessary to detect discrepancies between affective expectations and stimuli’s real affective potential and therefore moderated the assimilation effect to affective expectations.

Increased hedonic differences despite increases in hedonic range

Viewing hedonically negative paintings increased the hedonic ratings of subsequently viewed test paintings (positive hedonic contrast; Experiment 1) and also increased the degree of preference between the test paintings (Experiments 2 and 3). This result differs from the reduction in hedonic preference (hedonic condensation) that accompanies negative hedonic contrast. It also differs from the reduction in perceived differences that usually accompanies expansion of stimulus range and that is predicted by numerous theories.     

Presentation Matters: The Effect of Wrapping Neatness on Gift Attitudes

While gift‐givers typically wrap gifts prior to presenting them, little is known about the effect of how the gift is wrapped on recipients’ expectations and attitudes toward the gift inside. We propose that when recipients open a gift from a friend, they like it less when the giver has wrapped it neatly as opposed to sloppily and we draw on expectation disconfirmation theory to explain the effect. Specifically, recipients set higher (lower) expectations for neatly (sloppily)‐wrapped gifts, making it harder (easier) for the gifts to meet these expectations, resulting in contrast effects that lead to less (more) positive attitudes toward the gifts once unwrapped. However, when the gift‐giver is an acquaintance, there is ambiguity in the relationship status and wrapping neatness serves as a cue about the relationship rather than the gift itself. This leads to assimilation effects where the recipient likes the gift more when neatly wrapped. We assess these effects across three studies and find that they hold for desirable, neutral, and undesirable gifts, as well as with both hypothetical and real gifts.     

Mere exposure effect: A consequence of direct and indirect fluency-preference links

In three experiments, picture quality between test items was manipulated to examine whether subjects' expectations about the fluency normally associated with these different stimuli might influence the effects of fluency on preference or familiarity-based recognition responses. The results showed that fluency due to pre-exposure influenced responses less when objects were presented with high picture quality, suggesting that attributions of fluency to preference and familiarity are adjusted according to expectations about the different test pictures. However, this expectations influence depended on subjects' awareness of these different quality levels. Indeed, imperceptible differences seemed not to induce expectations about the test item fluency. In this context, fluency due to both picture quality and pre-exposure influenced direct responses. Conversely, obvious, and noticed, differences in test picture quality did no affect responses, suggesting that expectations moderated attributions of fluency only when fluency normally associated with these different stimuli was perceptible but difficult to assess.     

The effect of global versus local processing styles on assimilation versus contrast in social judgment

The authors propose a global/local processing style model (GLOMO) for assimilation and contrast effects in social judgment. GLOMO is based on Schwarz and Bless' (1992, 2007) inclusion-exclusion model, which suggests that when information is included into a category, assimilation occurs, whereas when information is excluded from a category, contrast occurs. According to GLOMO, inclusion versus exclusion should be influenced by whether people process information globally or locally. In 5 experiments, using both disambiguation and social comparison, the authors induced local versus global processing through perceptual tasks and time perspective and showed that global processing produced assimilation, whereas local processing produced contrast. The experiments showed that processing styles elicited in one task can carry over to other tasks and influence social judgments. Furthermore, they found that hemisphere activation and accessibility of judgment-consistent knowledge partially mediated these effects. Implications for current and classic models of social judgment are discussed.     

Hedonic contrast and condensation: Good stimuli make mediocre stimuli less good and less different

Loud sounds make soft sounds softer (contrast) and also make them less discriminable (which we callcondensation). We report on parallel phenomena in hedonics: Good stimuli reduce the pleasantness of less good stimuli, and also reduce people’s preferences among the less good stimuli. In Experiment 1, subjects rated the pleasantness of fruit juices diluted to approximate hedonic neutrality. Subjects who had just previously drunk and rated some good-tasting full-strength juices rated the diluted juices lower than did subjects who had not (hedonic contrast). In Experiment 2, subjects drank pairs of diluted juices and rated their preference for one juice over the other. Subjects who had just previously drunk and rated pairs of full-strength juices gave lower preference ratings between the diluted juices than did subjects who had not (condensation). Thus the same stimulus set produced contrast in Experiment 1 and condensation in Experiment 2, paralleling results in loudness.     

Affective Reactions to the Thought of “God”: Moderating Effects of Image of God

Recent understanding of subjective well-being suggests that it consists of global judgments of life satisfaction, hedonic experiences, and beliefs about facets of one’s life. Traditionally, life satisfaction judgments have been the outcome of interest in studies examining the relationship between religiosity and well-being. Two studies were conducted to look at the interactive effects of personal religious beliefs, namely God images, and environmental stimuli, particularly priming the thought of “God.” The first study examines hedonic experiences, which is one of the information sources when constructing a well-being judgment. A second study attempts to replicate the findings with life satisfaction ratings. Results of the first study showed that one’s image of God as a controlling or non-controlling entity moderated the affective response to being primed to think about God. In particular, those who had a high controlling image of God had a negative affective reaction to the God prime. Results of the second study replicated the pattern of results using life satisfaction ratings as the dependent variable.     

Assimilation and contrast in perceptual judgments

An attempt is made to specify the differential conditions underlying two opposite context effects: assimilation and contrast. Assimilation occurs when the judgment of the current stimulus shifts in the direction of the preceding stimulus; contrast occurs when the judgment shifts in the opposite direction. Both effects are brought together and demonstrated in a single paradigm. It is hypothesized that the number of contextual stimuli is the differentiating factor. Two alternative hypotheses, the differential stimulation hypothesis and the temporal position hypothesis, are also tested. The differential stimulation hypothesis proposes that the intensity difference between the contextual and judged stimulus determines whether assimilation or contrast occur, and the temporal position hypothesis proposes that varying the temporal position of the contextual stimulus is the critical factor. While the results do not support either of these alternative hypotheses, it is shown that the number of contextual stimuli does determine whether assimilation or contrast occur.     

Category size and judgments of variability: The effects of seeing the trees in the forest1

Abstract: Competing predictions about the effects of category size on judgments of category variability were examined in two studies involving the presentation of exemplars of two artificial social groups. In contrast to predictions of some exemplar-based models, Experiment 1 demonstrated that a numerically smaller group was perceived to be more variable than a larger group on the standard deviation measure of frequency distribution estimates. The result was interpreted to be an effect of differential information load. Experiment 2 revealed that variability judgments were influenced by prior expectations about the central tendencies as well as by practice in retrieving information about category exemplars. When frequency distribution estimates were made subsequent to abstract tasks, expectations about the numerical majority reduced perceived variability, while this influence was mitigated when memory measures preceded the frequency estimates.     

Decision mechanisms underlying mood-congruent emotional classification

There is great interest in understanding whether and how mood influences affective processing. Results in the literature have been mixed: some studies show mood-congruent processing but others do not. One limitation of previous work is that decision components for affective processing and responses biases are not dissociated. The present study explored the roles of affective processing and response biases using a drift-diffusion model (DDM) of simple choice. In two experiments, participants decided if words were emotionally positive or negative while listening to music that induced positive or negative mood. The behavioural results showed weak, inconsistent mood-congruency effects. In contrast, the DDM showed consistent effects that were selectively driven by an a-priori bias in response expectation, suggesting that music-induced mood influences expectations about the emotionality of upcoming stimuli, but not the emotionality of the stimuli themselves. Implications for future studies of emotional classification and mood are subsequently discussed.     

Choice‐making,Expectations, and Treatment Positivity: How and When Choosing Shapes Aversive Experiences

Every day we use products and treatments with unknown but expected effects, such as using medication to manage pain. In many cases, we have a choice over which products or treatments to use; however, in other cases, people choose for us or choices are unavailable. Does choosing (versus not choosing) have implications for how a product or treatment is experienced? The current experiments examined the role of choice‐making in facilitating so‐called expectation assimilation effects—or situations in which a person's experiences (e.g., discomfort and pain) are evaluated in a manner consistent with their expectations. In Experiment 1, participants were initially exposed to a baseline set of aversive stimuli (i.e., sounds). Next, some participants were given expectations for two “treatments” (i.e., changes in screen display) that could ostensibly reduce discomfort. Critically, participants were either given a choice or not about which of the two treatments they preferred. Participants in a control condition were not provided with treatment expectations. Results revealed that discomfort experiences assimilated to expectations only when participants were provided with choice. Experiment 2 replicated this finding and provided evidence against the idea that demand characteristics and choice‐making unrelated to the core task (i.e., choices without associated expectations) could account for the results. Further, Experiment 2 showed that choosing reduced discomfort because of increased positivity about the treatment. Results are discussed in the context of extant research on choice‐making and expectation effects. Copyright © 2013 John Wiley & Sons, Ltd.     

Self‐efficacy in the Workplace: Linking personality to domain‐specific efficacy beliefs

Based on a social cognitive approach to personality, the role of domain‐specific efficacy beliefs were examined in two studies. Study 1 developed a measure of expectations about success in 10 different domains of common work activities with domain‐specific expectancy ratings obtained for 157 individuals along with self‐ and peer ratings of personality. Results showed that predictable relationships emerged, with the traits of the five‐factor model being important determinants of construct‐relevant efficacy beliefs. Study 2 focused on expectations about activities related to conscientiousness as a link between personality and performance across jobs. Results (N = 97) confirmed the proposed relationships and found that efficacy beliefs about trait‐relevant tasks functioned as a mediator linking conscientious and supervisor ratings of performance.     

Context effects on the perceived physical attractiveness of faces

Four experiments were conducted to study the nature of context effects on the perceived physical attractiveness of faces. In Experiment 1, photos of faces scaled on attractiveness were presented in sets of three, with target faces appearing in the middle flanked by two context faces. The target faces were of average attractiveness, with the context faces being either high, average, or low in attractiveness. The effect of the context was one of assimilation, rather than contrast, regardless of whether the persons in the photos were portrayed to be associated. This result was interpreted in terms of a “generalized halo effect” for judgments of the physical attractiveness of stimuli within a group. Presenting the persons of a set as friends enhanced the perceived attractiveness of the target face but only when the context did not contain a face of low attractiveness. In Experiment 2, the assimilation effect was observed to carry over to influence ratings of the target faces several minutes after the context faces had been removed. Experiment 3 showed the assimilation effect to be robust regardless of whether the context was composed of two faces or one, but Experiment 4 showed the assimilation effect to be evident only when the context faces were presented simultaneously with the target.
