Once more: is beauty in the eye of the beholder? Relative contributions of private and shared taste to judgments of facial attractiveness.

Misconstruing the meaning of Cronbach's alpha, experts on facial attractiveness have conveyed the impression that facial-attractiveness judgment standards are largely shared. This claim is unsubstantiated, because information necessary for deciding whether judgments of facial attractiveness are more influenced by commonly shared or by privately held evaluation standards is lacking. Three experiments, using diverse face and rater samples to investigate the relative contributions of private and shared taste to judgments of facial attractiveness, are reported. These experiments show that for a variety of ancillary conditions, and contrary to the prevalent notion in the literature, private taste is about as powerful as shared taste. Important implications for scientific research strategy and laypeople's self-esteem are discussed.

Judgment dissociation theory: an analysis of differences in causal, counterfactual, and covariational reasoning.

Research suggests that causal judgment is influenced primarily by counterfactual or covariational reasoning. In contrast, the author of this article develops judgment dissociation theory (JDT), which predicts that these types of reasoning differ in function and can lead to divergent judgments. The actuality principle proposes that causal selections focus on antecedents that are sufficient to generate the actual outcome. The substitution principle proposes that ad hoc categorization plays a key role in counterfactual and covariational reasoning such that counterfactual selections focus on antecedents that would have been sufficient to prevent the outcome or something like it and covariational selections focus on antecedents that yield the largest increase in the probability of the outcome or something like it. The findings of 4 experiments support JDT but not the competing counterfactual and covariational accounts.

The effects of assessment type on verbal ratings of conditional stimulus valence and contingency judgments: implications for the extinction of evaluative learning.

Recent research on causal learning found (a) that causal judgments reflect either the current predictive value of a conditional stimulus (CS) or an integration across the experimental contingencies used in the entire experiment and (b) that postexperimental judgments, rather than the CS's current predictive value, are likely to reflect this integration. In the current study, the authors examined whether verbal valence ratings were subject to similar integration. Assessments of stimulus valence and contingencies responded similarly to variations of reporting requirements, contingency reversal, and extinction, reflecting either current or integrated values. However, affective learning required more trials to reflect a contingency change than did contingency judgments. The integration of valence assessments across training and the fact that affective learning is slow to reflect contingency changes can provide an alternative interpretation for researchers' previous failures to find an effect of extinction training on verbal reports of CS valence.

Making causal judgments from the proportion of confirming instances: the pCI rule.

It is proposed that causal judgments about contingency information are derived from the proportion of confirmatory instances (pCI) that are evaluated as confirmatory for the causal candidate. In 6 experiments, pCI values were manipulated independently of objective contingencies assessed by the deltaP rule. Significant effects of the pCI manipulations were found in all cases, but causal judgments did not vary significantly with objective contingencies when pCI was held constant. The experiments used a variety of stimulus presentation procedures and different dependent measures. The power PC theory, a weighted version of the deltaP rule, the Rescorla-Wagner associative learning model (R. A. Rescorla & A. R Wagner, 1972), and the deltaD rule, which is the frequency-based version of the pCI rule, were unable to account for the significant effects of the pCI manipulations. These results are consistent with a general explanatory approach to causal judgment involving the evaluation of evidence and updating of beliefs with regard to causal hypotheses.

Typical versus atypical unpacking and superadditive probability judgment.

Probability judgments for packed descriptions of events (e.g., the probability that a businessman does business with a European country) are compared with judgments for unpacked descriptions of the same events (e.g., the probability that a businessman does business with England, France, or some other European country). The prediction that unpacking can decrease probability judgments, derived from the hypothesis that category descriptions are interpreted narrowly in terms of typical instances, is contrasted to the prediction of support theory that unpacking will generally increase judged probabilities (A. Tversky & D. J. Koehler, 1994). The authors varied the typicality of unpacked instances and found no effect of unpacking with typical instances (additivity) and a negative effect with atypical instances (superadditivity). Support theory cannot account for these findings in its current formulation.

Reference-frame misalignment and cardinal direction judgments: group differences and strategies.

In 3 experiments, the authors examined how misalignment of egocentric and exocentric reference frames affects cardinal direction judgments. Experiments 1 and 2 demonstrated large differences in the accuracy and speed with which 104 less experienced and 7 experienced navigators made cardinal direction judgments. Reference-frame misalignment was associated with large performance decrements. The extent of these decrements diminished as ability and experience increased: however, even experienced navigators showed decrements when reference frames were misaligned. In Experiment 3, the authors used 55 college students to examine the individual subtasks of a common strategy for cardinal direction judgments and to isolate the effects of reference-frame misalignment to a particular subtask of this strategy. The tasks and strategies studied in this article can be applied in the development of navigational training and interfaces.

Perspective-taking judgments among young adults, middle-aged, and elderly people.

Perspective-taking judgments among young adults, middle-aged, and elderly people were examined. In 1 condition, participants were instructed to judge the likelihood of acceptance of a painkiller as a function of 3 cues: severity of the condition, potential side effects, and level of trust in the health care provider. In the other condition, participants were instructed to judge the likelihood of purchasing pieces of clothing. Judgments were given from 2 viewpoints: the viewpoint of another person known to place no importance on one of the 3 cues, and the viewpoint of another person known to place very great importance on this cue. The hypotheses were that elderly people would not, to the same extent as young adults, be likely to discount the impact of the "no-importance" cue, and to magnify the impact of the "very important" cue. In both judgment situations, the results support these hypotheses.

Evolving judgments of terror risks: foresight, hindsight, and emotion.

The authors examined the evolution of cognitive and emotional responses to terror risks for a nationally representative sample of Americans between late 2001 and late 2002. Respondents' risk judgments changed in ways consistent with their reported personal experiences. However, they did not recognize these changes, producing hindsight bias in memories for their judgments. An intensive debiasing procedure failed to restore a foresightful perspective. A fear-inducing manipulation increased risk estimates, whereas an anger-inducing manipulation reduced them-both in predictions (as previously observed) and in memories and judgments of past risks. Thus, priming emotions shaped not only perceptions of an abstract future but also perceptions of a concrete past. These results suggest how psychological research can help to ensure an informed public.

Influence of virtual reality training on the roadside crossing judgments of child pedestrians.

The roadside crossing judgments of children aged 7, 9, and 11 years were assessed relative to controls before and after training with a computer-simulated traffic environment. Trained children crossed more quickly, and their estimated crossing times became better aligned with actual crossing times. They crossed more promptly, missed fewer safe opportunities to cross, accepted smaller traffic gaps without increasing the number of risky crossings, and showed better conceptual understanding of the factors to be considered when making crossing judgments. All age groups improved to the same extent, and there was no deterioration when children were retested 8 months later. The results are discussed in relation to theoretical arguments concerning the extent to which children's pedestrian judgments are amenable to training.

Word recognition and temporal order judgments: semantics turns back the clock.

This paper examines the consequences that codes activated during reading have on activities unrelated to reading by investigating the effects of semantics on temporal order judgments. Participants judged which of two word targets appeared first. Targets appeared either synchronously, or were separated by varying stimulus onset asynchronies (SOAs). For one group of participants, one target on each trial was related to a prime word shown at the beginning of the trial. This priming relation affected temporal order judgments such that participants sometimes reported related targets as having appeared first, even when they appeared second. It is suggested that this effect is best explained as showing that codes activated during word recognition affect the attentional selection aspects of the temporal order judgment task.

The influence of multiple presentations on judgments of children's phonetic accuracy.

Two experiments examined whether listening to multiple presentations of recorded speech stimuli influences the reliability and accuracy of judgments of children's speech production accuracy. In Experiment 1, 10 listeners phonetically transcribed words produced by children with phonological impairments after a single presentation and after the word was played 7 times. Inter- and intratranscriber reliability in the single- and multiple-presentation conditions did not differ significantly. In Experiment 2, 18 listeners provided binary correct/incorrect judgments of /s/ accuracy in single- and multiple-presentation conditions. There was no systematic effect of presentation condition on either accuracy or intrarater reliability. However, greater interrater reliability was noted in the multiple-presentation condition, particularly for tokens of /s/ that were incorrect or acoustically intermediate between an incorrect and a correct /s/. Taken together, the results suggest that multiple presentations have no measurable effect on the accuracy and intrarater reliability of judgments of children's phonetic accuracy, but that they do have a small effect on interrater reliability. Clinical implications are discussed.

Clinical judgment and computers.

The increasingly frequent application of formal methods, including algorithms and computer programs, to processes that are ordinarily viewed as judgmental seems to be a source of both promise and unease for physicians. A consideration of some of these methods suggests that it may be helpful to attempt to distinguish carefully between judgment and computation. Medical care involves a complex of inferential processes, any of which may be performed as judgments, and some of which may be carried out as a computation. My purpose here is to identify the latter cases. The empirical evidence suggests that such a demarcation is feasible. The most important question appears not to be "Where can we use computers?" but "Where must we use human beings?" Until this matter is more thoroughly explored, tension between physicians and computer advocates will persist.

Cognitive styles: errors in directional judgments.

Previous studies on spatial memory have shown that, in judging direction, participants are more accurate and faster when a map is aligned with the perspective of the spatial layout they had learned (alignment effect). Rossano and Warren (1989 Perception 18 215-229) have shown that when participants have to do a contra-aligned judgment they can either answer correctly, or make alignment or mirror-image errors. We think that the kind of response depends on the different way in which people acquire environmental knowledge: landmark, route, and survey. We hypothesise that landmark and route participants show alignment effects and make, respectively, alignment errors and mirror-image errors, whereas survey participants do not show an alignment effect. An experiment is reported in which participants performed three tasks in order to distinguish their cognitive style. We selected thirty landmark, thirty route, and twenty-eight survey participants. They were then submitted to directional judgment tasks to verify whether the alignment effect was present and to observe the kind of responses. The results revealed that survey participants did not show an alignment effect, and that the kind of errors could depend on the directional judgment task participants had to do, and not only on the cognitive style.

Numerosity judgments for tactile stimuli distributed over the body surface.

A large body of research now supports the claim that two different and dissociable processes are involved in making numerosity judgments regarding visual stimuli: subitising (fast and nearly errorless) for up to 4 stimuli, and counting (slow and error-prone) when more than 4 stimuli are presented. We studied tactile numerosity judgments for combinations of 1-7 vibrotactile stimuli presented simultaneously over the body surface. In experiment 1, the stimuli were presented once, while in experiment 2 conditions of single presentation and repeated presentation of the stimulus were compared. Neither experiment provided any evidence for a discontinuity in the slope of either the RT or error data suggesting that subitisation does not occur for tactile stimuli. By systematically varying the intensity of the vibrotactile stimuli in experiment 3, we were able to demonstrate that participants were not simply using the 'global intensity' of the whole tactile display to make their tactile numerosity judgments, but were, instead, using information concerning the number of tactors activated. The results of the three experiments reported here are discussed in relation to current theories of counting and subitising, and potential implications for the design of tactile user interfaces are highlighted.

Naïve and experienced judgments of stimulus-response compatibility: implications for interface design.

Many design guidelines encourage maintaining stimulus-response compatibility whenever possible. Payne found that naïve judgments for different stimulus-response (S-R) mappings were not very accurate, and suggested that designers may not be able to predict whether a particular display-control configuration will lead to better performance than another. Three experiments were conducted to determine whether naïve judgments for two-choice tasks in which stimuli and responses involve left-right spatial information are sensitive to (a) the influence of S-R mode relations and (b) pure versus mixed presentation of compatible and incompatible mappings. Initial performance judgments for these conditions were not very accurate, nor were those for four-choice tasks of the type studied by Payne, but subjects' estimates of performance improved with relatively little experience using the different S-R configurations.

Empathy and pseudo-empathy: the affective judgments of first- and third-graders.

Eighty male and female first- and third-grader Ss were presented one of two brief videotaped social interaction episodes. Half of the Ss viewed an unambiguous tape in which a target character's affective response was congruent with the situational context in which he operated. The remaining Ss viewed a similar, but ambiguous tape in which the nonverbal affective response of the target character was incongruent with situational demands. Ss' responses were scored on the basis of their judgments of the target character's affective state and facial expression, and the degree of relative certainty with which they made their affective judgments. No differences were predicted or found in any of the empathic responses of first- and third-graders to the unambiguous tape. The two age groups studied did, however, differ significantly in their responses to the ambiguous tape. As anticipated, the first-grade Ss employed a highly centered inference strategy and based their judgments on only one of the available incongruous cues. The older Ss, by contrast, recognized the incongruities present and expressed little confidence in their ability to infer the true affect state of the target character.

Moral judgment in retarded and nonretarded school age children.

The moral judgment of 135 normal, educable retarded, and trainable retarded boys and girls (ages 6-10, 11-13, and 14-16) was individually assessed to determine the significance of chronological age and IQ on moral development. The results indicated significant differences in mean normal judgment between the groups and each age level. The findings were interpreted as substantiating Piaget's stage theory of moral development and suggesting that within the retarded population, level of intellectual ability is also significantly related to moral judgment.
