Tooth color: effects on judgments of attractiveness and age

Tooth whitening has become a very popular procedure. Advertisements for whitening products imply that whiter teeth are more attractive than yellower teeth. We tested this idea empirically by manipulating the tooth color of pictures of male and female targets. Participants' ratings of attractiveness were not influenced by tooth color. Exp. 2 yielded a negative correlation between attractiveness and age ratings: targets judged to be older were rated as less attractive. Unless whiter teeth help in some other way, e.g., improved self-esteem or confidence, it seems that tooth whitening procedures or products are not associated with increased attractiveness to others.     

Action perception and outcome valence: effects on children's inferences of intentionality and moral and liking judgments.

The influences of different action-outcome scenarios on children's evaluative judgments and inferences of outcome intentionality were assessed. One hundred forty-five kindergartners, 2nd graders, and 4th graders heard 4 stories about child actors who engaged in 1 action or 3 equifinal actions and caused a positive or negative outcome. The stories made no mention of the actors' anticipated outcome so that we could assess the children's inferences of whether the actors wanted and had tried to cause the outcome. Children also rated their liking for the actors and the actors' morality. Children's moral and liking judgments were not significantly differentiated by action condition. However, actors who caused positive outcomes received favorable liking and moral judgments, and actors who caused negative outcomes received neutral liking and moral judgments. Children's intentionality inferences varied by the actors' actions and were moderated by outcome valence. The authors discuss children's apparent use of the valence rule when inferring intentionality and their reluctance to judge harshly actors who cause negative outcomes when not privy to the actors' intentions.     

Inferences about character and motive influence intentionality attributions about side effects

In two studies, we predicted and found that inferences about motive and character influence intentionality attributions about foreseeable consequences of action (i.e., side effects). First, we show that inferences about intentionality are greater for good side effects than bad side effects when a target person's character is described positively. In Study 2, we manipulated information about a target person and found that inferences about intentionality were greater when side effects were consistent with a target person's character and motives. Overall, our data cast doubt on the generality of the side-effect effect. We discuss our findings and their implications for future research on intentionality and social perception.     

Facial appearance and judgments of credibility: the effects of facial babyishness and age on statement credibility

Researchers have found that facial appearance influences social judgments. For example, evidence has shown that facial babyishness and age affect perceivers' impressions of the stimulus person's veracity. In this experiment, the researchers examined whether these variables also influenced the credibility attributed to written statements purportedly made by these people in addition to several topics of interest in deception-detection research. Undergraduates (N = 270) were presented babyfaced or mature-faced photographs that depicted a child, an adult, or an older individual, in addition to a written truthful or deceptive statement purportedly made by the person in the photograph. Results showed that, as predicted, when the statements were accompanied by babyfaced pictures, participants tended to judge them as truthful, but only if the pictures did not depict children. Also, when the statements were accompanied by childen's pictures, participants tended to judge them as deceptive, but only if the pictures depicted a babyish face. Overall detection accuracy was close to chance and did not correlate with either judgmental confidence or with the respondents' estimated lie-detection accuracy. However, confidence and estimated ability were significantly correlated. Also, more confidence was placed in judgments of truthfulness than in judgments of deceptiveness. Respondents' truth bias and the existence of a veracity effect in the diverse experimental conditions were examined as well.     

Judgments about judgments: the dissociation of consideration price and transaction commitment judgments

There are many contexts in which people make judgments about prior judgments. For example, Internet shopping bots (e.g., NexTag.com) allow consumers to search for products and, if the price is too high, list a price at which they would consider making the purchase (i.e., base judgment). If the price drops to this level, the vendor generates an e-mail inviting the consumer to execute the transaction at the reduced price (i.e., contingent judgment). The authors show that the consideration price depends on the content of retrieved information, whereas the willingness to execute the transaction at the consideration price depends on the ease-of-retrieving the information. The authors use different offer prices to encourage the consumer to retrieve information consistent with different product quality levels. The authors also select offer prices so that information retrieval is more difficult at moderate offer prices than at high or low offer prices. Accordingly, the authors show that the consideration price increases as the offer price increases, but the willingness to execute the transaction at the consideration price is greater when there are high and low, as opposed to moderate, offer prices.     

Justice motive effects in ageism: The effects of a victim's age on observer perceptions of injustice and punishment judgments

Drawing on just-world theory and research showing that older persons are generally assigned a devalued status in society, we examined the impact of an innocent victim's age on observer perceptions of injustice and punishment reactions. In three experiments, we demonstrated that observers perceived the suffering of an older (vs. younger) person as less unfair, which, in turn, reduced their willingness to punish the harm doer. In Study 1, participants rated a car accident as less unfair and consequently punished the harm doer less when the victim was older. In Study 2, participants recommended punishing a harm doer less when the victim was older (vs. younger) when the need to believe in a just world was threatened (i.e., only when the victim was innocent). In Study 3, only participants higher in ageism perceived the suffering of an older (vs. younger) victim as less unfair and, consequently, recommended less punishment for the harm doer.     

Judgments of cause and blame: the effects of intentionality and foreseeability

What are the factors that influence everyday attributions of cause and blame? The current studies focus on sequences of events that lead to adverse outcomes, and examine people's cause and blame ratings for key events in these sequences. Experiment 1 manipulated the intentional status of candidate causes and their location in a causal chain. Participants rated intentional actions as more causal, and more blameworthy, than unintentional actions or physical events. There was also an overall effect of location, with later events assigned higher ratings than earlier events. Experiment 2 manipulated both intentionality and foreseeability. The preference for intentional actions was replicated, and there was a strong influence of foreseeability: actions were rated as more causal and more blameworthy when they were highly foreseeable. These findings are interpreted within two prominent theories of blame, [Shaver, K. G. (1985). The attribution of blame: Causality, responsibility, and blameworthiness. New York: Springer-Verlag] and [Alicke, M. D. (2000). Culpable control and the psychology of blame. Psychological Bulletin, 126, 556-574]. Overall, it is argued that the data are more consistent with Alicke's model of culpable control.     

The effects of base rates and individuating information on judgments about another person

Past research suggests that in judging a person's category membership, people largely ignore the population frequency of membership in the category (base rates) in favor of individuating information about the particular person. This study tested the hypothesis that base rates will be utilized to the extent that the usefulness of the individuating information for diagnosing category membership is diminished. Subjects were given problems in which both base rates of membership in each of two categories and individuating information about a target person were presented. Then, in each case, they were asked to assess the probability that the target person belonged to each category. In three sets of problems, the diagnostic usefulness of the individuating information (personality characteristics) was diminished by including individuating information that was either inconsistent or irrelevant, or by increasing the similarity of the two alternative membership categories. In a fourth set of problems, the individualistic information included consistent, relevant personal characteristics and the membership categories were dissimilar. As expected, base rates were used in each of the first three sets of problems but were ignored in the fourth set. The results were interpreted in terms of informational factors that induce a shift away from a habitual, spontaneous reliance on a source of information (e.g., personality traits) for which one has well-developed rules (e.g., intuitive personality theories), and toward a more controlled, deliberate mode of thinking wherein other sources of information (e.g., base rates) are attended to and incorporated into judgment through less frequently used rules (e.g., sampling rules).     

The effects of feedback about self and others on the recall and judgments of feedback-relevant information

After people have received feedback about the outcome of their behavior, their responses to information bearing on the validity of this feedback may be influenced by their desire to maintain a favorable self-image. This experiment investigated the cognitive mediators of these responses. Subjects who received negative feedback about their performance on an intelligence test disparaged intelligence tests in general and judged a report they had read to be unfavorable to intelligence tests. Nevertheless, they recalled more arguments in the report that were favorable to intelligence tests than did positive feedback recipients. These results contradicted the hypothesis that subjects selectively attend to information that helps them to maintain a positive self-concept in light of negative information about themselves. Rather, they may attempt to refute arguments that support the validity of the negative feedback they receive, and this relatively greater processing may facilitate the recall of these arguments later on. In contrast, there was no evidence that subjects try to refute information that calls the validity of positive feedback into question. Results had implications for two additional issues: first, whether the effect of performance feedback depends on whether it is received before or after information bearing on its validity; second, whether feedback has similar effects on recall and judgments by persons to whom it does not directly pertain.     

What you know can hurt you: effects of age and prior knowledge on the accuracy of judgments of learning

How do aging and prior knowledge affect memory and metamemory? We explored this question in the context of a dual-process approach to Judgments of Learning (JOLs), which require people to predict their ability to remember information at a later time. Young and older adults (n = 36, mean ages = 20.2 & 73.1) studied the names of actors who were famous in the 1950s or 1990s, providing a JOL for each. Recognition memory for studied and unstudied actors was then assessed using a Recollect/Know/No-Memory (R/K/N) judgment task. Results showed that prior knowledge increased recollection in both age groups such that older adults recollected significantly more 1950s actors than younger adults. Also, for both age groups and both decades, actors judged R at test garnered significantly higher JOLs at study than actors judged K or N. However, while the young showed benefits of prior knowledge on relative JOL accuracy, older adults did not, showing lower levels of JOL accuracy for 1950s actors despite having higher recollection for, and knowledge about, those actors. Overall, the data suggest that prior knowledge can be a double-edged sword, increasing the availability of details that can support later recollection, but also increasing nondiagnostic feelings of familiarity that can reduce the accuracy of memory predictions.     

Note-taking in the employment interview: effects on recall and judgments

Although note-taking in the employment interview is highly recommended, little research has examined its effects. This study investigated the effects of note-taking styles, review of the notes, and content of the notes on participants' cued recall of information and decisions made from videotaped employment interviews. Note-taking increased recall accuracy but not judgment accuracy. Being able to review notes resulted in increased judgment accuracy for those taking conventional-style notes. The content of the notes also had important implications for conventional note-takers, suggesting some benefits of recording notes using the key-points style. The findings suggest that the act of note-taking may be more important for memory and legal reasons than for improving the decisions made by interviewers.     

Anchoring effects on performance judgments

Three studies were conducted investigating the effects of irrelevant anchors on performance judgments. Both a lab and field study demonstrated that an alternative anchoring manipulation that did not involve an explicit comparative question had effects on performance judgments similar to a traditional anchoring manipulation. The final study examined whether the anchoring effects were more likely when the anchor was highly applicable to the final judgment. The results indicated that both highly applicable and low applicable anchors produced an anchoring effect, but the highly applicable anchors had a larger effect on performance judgments. Evidence was also found for asymmetrical anchoring effects. In two of the three studies, high anchors increased performance judgments relative to the control group, whereas low anchors were not significantly different from the control group.     

Children's equivalence judgments: Crossmapping effects

Preschoolers made numerical comparisons between sets with varying degrees of shared surface similarity. When surface similarity was pitted against numerical equivalence (i.e., crossmapping), children made fewer number matches than when surface similarity was neutral (i.e, all sets contained the same objects). Only children who understood the number words for the target sets performed above chance in the crossmapping condition. These findings are consistent with previous research on children's non-numerical comparisons (e.g., [Rattermann, M. J., & Gentner, D. (1998). The effect of language on similarity: The use of relational labels improves young children's performance in a mapping task. In K. Holyoak, D. Gentner, & B. Kokinov (Eds.), Advances in analogy research: Integration of theory and data from cognitive, computational, and neural sciences (pp. 274–282). Sofia: New Bulgarian University; Smith, L. B. (1993). The concept of same. In H. W. Reese (Ed.), Advances in child development and behavior, Vol. 24 (pp. 215–252). New York: Academic Press]) and suggest that the same mechanisms may underlie numerical development.     

Self-serving judgments about winning the lottery

Although myths and stereotypes about lottery winners tend to be negative (e.g., winners become extravagant), people continue to spend billions of dollars buying lottery tickets in the hope of winning. The authors applied findings from the self-enhancement literature to understand this paradox. Eighty college students received class credit for their participation, in which they read a scenario that asked them to imagine that they, or a target other, had won a lottery. Participants' responses to a 34-item questionnaire displayed a self-serving bias, such that changes to the self were expected to be more positive than changes to the other. For several items, this effect was moderated by the participant's gender. The present research indicates that the pervasive tendency to display self-serving biases can apply to future-oriented processing, an under-researched topic.

Sensory effects on judgments of short time-intervals

Two experiments were conducted to test the effect of nontemporal factors on duration discrimination. In Exp. 1, a forced-choice adaptive procedure with a standard duration of 400 or 800 ms was employed. It was shown that, for both auditory and visual modes, the discrimination is better with empty intervals (a silent period between two brief signals) than with filled intervals (a continuous signal), but only with shorter durations. In a second experiment, where intervals of the same duration range were employed but were presented with a single-stimulus method, discrimination was better with empty than with filled intervals, and this effect applied to both ranges of duration and both sensory modes. In both experiments, discrimination was better in the auditory than in the visual mode. These data are discussed in the context of current models of timing mechanisms.

On being sad and mistaken: mood effects on the accuracy of thin-slice judgments

A series of studies explored how sadness impacts the accuracy of social judgments. In Study 1, induced sadness led to reduced accuracy in judgments of teacher effectiveness from brief samples of nonverbal behavior (thin slices). In Study 2, sad participants showed reduced accuracy in judging relationship type from thin slices as well as diminished judgmental efficiency. Study 3 revealed that higher Beck Depression Inventory scores were associated with diminished accuracy on the Profile of Nonverbal Sensitivity. Finally, Study 4 tested the possibility that sadness impairs accuracy by promoting a more deliberative information-processing style. As expected, accuracy was higher among participants in a sad mood condition who completed the judgment task while simultaneously performing a distracting cognitive load task.
