Biases in social comparative judgments: the role of nonmotivated factors in above-average and comparative-optimism effects.

Biases in social comparative judgments, such as those illustrated by above-average and comparative-optimism effects, are often regarded as products of motivated reasoning (e.g., self-enhancement). These effects, however, can also be produced by information-processing limitations or aspects of judgment processes that are not necessarily biased by motivational factors. In this article, the authors briefly review motivational accounts of biased comparative judgments, introduce a 3-stage model for understanding how people make comparative judgments, and then describe how various nonmotivational factors can influence the 3 stages of the comparative judgment process. Finally, the authors discuss several unresolved issues highlighted by their analysis, such as the interrelation between motivated and nonmotivated sources of bias and the influence of nonmotivated sources of bias on behavior.

Time-to-contact judgments of an approaching object that is partially concealed by an occluder.

Prior studies of time-to-contact (TTC) focused on judgments of unoccluded approaching objects. P. R. DeLucia, M. K. Kaiser, J. M. Bush, L. E. Meyer, and B. T. Sweet (2003) showed that partial occlusion decreases an object's optical size and expansion rate and that the value of tau derived from the reduced optical size (relative rate of accretion; RRA) does not necessarily correspond to TTC. In the present study, a computer-generated object approached the observer while unoccluded or partially concealed by a stationary or moving occluder. In some scenes, the occluder's motion nullified the object's optical expansion. Results indicated that stationary and moving occluders affected TTC judgments. RRA predicted directional changes in TTC judgments but predicted larger changes in such judgments than were observed. Tau did not predict effects of occlusion. When developing models of perceived collision, it is important to consider effects of partial occlusion on optical TTC information and on TTC judgments.

Dissociation between judgments and outcome-expectancy measures in covariation learning: a signal detection theory approach.

A number of studies using trial-by-trial learning tasks have shown that judgments of covariation between a cue c and an outcome o deviate from normative metrics. Parameters based on trial-by-trial predictions were estimated from signal detection theory (SDT) in a standard causal learning task. Results showed that manipulations of P(c) when contingency (deltaP) was held constant did not affect participants' ability to predict the appearance of the outcome (d') but had a significant effect on response criterion (c) and numerical causal judgments. The association between criterion c and judgment was further demonstrated in 2 experiments in which the criterion was directly manipulated by linking payoffs to the predictive responses made by learners. In all cases, the more liberal the criterion c was, the higher judgments were. The results imply that the mechanisms underlying the elaboration of judgments and those involved in the elaboration of predictive responses are partially dissociable.

On the role of causal intervention in multiple-cue judgment: positive and negative effects on learning.

Previous studies have suggested better learning when people actively intervene rather than when they passively observe the stimuli in a judgment task. In 4 experiments, the authors investigated the hypothesis that this improvement is associated with a shift from exemplar memory to cue abstraction. In a multiple-cue judgment task with continuous cues, the data replicated the improvement with intervention and participants who experimented more actively produced more accurate judgments. In a multiple-cue judgment task with binary cues, intervention produced poorer accuracy and participants who experimented more actively produced poorer judgments. These results provide no support for a representational shift but suggest that the improvement with active intervention may be limited to certain tasks and environments.

Does aging influence people's metacomprehension? Effects of processing ease on judgments of text learning.

In 2 experiments, the authors investigated whether age-related differences exist in metacomprehension by evaluating predictions based on the ease-of-processing (EOP) hypothesis. According to this hypothesis, judgments of how well a text has been learned are based on how easily each text was processed; easier processing results in higher judgments. Participants read either sentence pairs or longer texts and judged their learning of each immediately afterward. Although an age-related difference in the use of processing ease in judgments was observed with sentence pairs, for longer texts older and younger adults' judgments were similarly related to processing ease. In both experiments, age equivalence was also evident in the accuracy of the judgments at predicting performance on the criterion test. The overall pattern of results suggests that judging text learning remains largely intact with aging.

Children's judgments of utterance appropriateness.

Judgments of utterance appropriateness were examined in 3-, 4-, 5-, and 6-year olds to examine the bases for these judgments in a variety of social contexts. The results indicated that the 4- and 5-year olds based their judgments in part on factors such as the available nonlinguistic evidence supporting the utterance and the types of evaluative terms used in the utterance. The judgments of the 6-year olds more closely resembled those of a group of adults, but their judgments were not yet free of some of the factors operative for the younger children. The findings are discussed in terms of the illocutionary and conversational characteristics of the stimulus utterances.

Time-interval analysis of interjudge and intrajudge agreement for stuttering event judgments.

In response to the recognized need for a valid and reliable way to measure stuttering, this study investigates a measurement methodology based on time-interval analyses of stuttering event judgments. Three groups of judges, differing in stuttering judgment experience, identified stuttering events in 12 repeated presentations of five 1-min speech samples. Fixed time intervals ranging from 0.2 sec to 7.0 sec were then superimposed on the event judgments by a data analysis program. Inter- and intrajudge interval-by-interval agreement, and agreement for total numbers of intervals containing stuttering event judgments, were calculated for each judge group. Results showed that agreement was superior among more experienced judges and in longer interval lengths. Agreement varied across speech samples but not across the repeated judgment opportunities. Agreement was maximized at greater than chance levels for an interval of approximately 3.0 sec, but even this best agreement did not exceed a mean of approximately 60% for experienced judges.

Familiarity influences judgments of sex: the case of voice recognition.

Two experiments are reported in which subjects made judgments about the sex or the familiarity of a voice. In experiment 1, subjects were fans of the BBC-radio soap opera, The Archers, and familiar voice clips were taken from this programme. Subjects showed a large reduction in response times when making sex judgments to familiar voices, despite the fact that sex judgments are generally much faster than familiarity judgments. In experiment 2, the same familiar clips were played to subjects unfamiliar with the soap opera, and no difference was observed in times to make sex judgments to Archers or non-Archers voices. We conclude that, unlike the case of face recognition, sex and identity processing of voices are not independent. The findings constrain models of person recognition across multiple modalities.

The influence of males and females on the psychophysical judgments of females.

A transfer paradigm was employed to test the hypothesis that females influenced by males on one task would show more carryover of the influence effect to other tasks than would females influenced by other females. Thirty female college students made judgments on three cross-modal matching tasks. Experimental subjects gave their judgments on one task along with two male or two female confederates, who appeared to give discrepant judgments. They then made another series of private judgments on the other two tasks. Comparison to a control group and to an original series of provate judgments revealed a significant direct influence effect, but minimal transfer to the other two tasks. There was a nonsignificant tendency for the subjects to be more directly influenced by other females than by males, but this influence by the other females was accompanied by a decline in task confidence. Influence by males on females did not result in lowered confidence. This finding may be restricted to quantitative tasks and to American college students.

First-year residents' caring, medical knowledge, and clinical judgment in relation to laboratory utilization.

PURPOSE: To investigate first-year residents' levels of caring (concern for others' well-being), medical knowledge, and clinical judgment in relation to their levels of laboratory utilization. METHOD: Self-report questionnaires about caring, knowledge, and judgment were given in 1986-87 to 36 first-year residents in a three-year internal medicine residency program of the McGaw Medical Center of Northwestern University. Inpatient laboratory utilization data obtained from structured chart audits over a one-year period were used to construct comparable diagnosis- and severity-specific physician practice profiles, from which the residents received overall utilization scores for laboratory test charges. Statistical methods included Cronbach's alpha reliability coefficient and multiple regression analysis. RESULTS: The multiple regression analysis showed that medical knowledge was an independent predictor of increased laboratory utilization (standardized beta = .54, p < .04, partial R2 = .07); clinical judgment was an independent predictor of decreased utilization (standardized beta = -.53, p < .05, partial R2 = .06); and caring was unrelated to utilization (standardized beta = .15, ns, partial R2 = .01). CONCLUSION: The finding that clinical judgment was related to less laboratory utilization suggests that future research should investigate the decision-making concomitants of judgment to better understand its translation into resource utilization. It is possible that the relationship between medical knowledge and laboratory utilization is developmentally specific, and thus the knowledge of more experienced physicians, who would likely be more precise decision makers than first-year residents, may be related to decreased rather than increased utilization.

Event-related potentials associated with judgment: comparison of S1- and S2-choice conditions in a contingent negative variation (CNV) paradigm.

To elucidate the functional role of association cortex in judgment and decision-making about external stimuli, the scalp topography of contingent negative variation (CNV) recorded in 9 normal volunteers was compared in two settings; dichotomous S1- and S2-choice paradigms using right wrist extension or flexion movement upon S2 as the choice reaction task with an S1-S2 interstimulus interval of 2 s. Two main findings were obtained. First, early CNV in the S1-choice paradigm consisted of a frontal to frontopolar midline negative potential, most likely representing judgment more than orienting response, and a left-sided parietal positive potential, at least partially representing P3b, whereas in the S2-choice paradigm it consisted only of a smaller frontal negative potential shift, most likely representing merely an orienting response. This suggests that the prefrontal and left parietal association cortexes might be active in the judgment and decision-making process. Second, after S2, two positive peaks (334 and 545 ms after S2) were observed at the midline central to left parietal areas only in the S2-choice paradigm. In the S1-choice paradigm, one large negative peak (275 ms after S2) was observed. We postulate that the first peak of the S2-choice paradigm is related to decision making or judgment and that the second peak is related to the following cognitive process. We conclude that at least the prefrontal and parietal association cortexes generate transient potentials accompanying judgment, and possibly decision making.

An empirical evaluation of three components of the tetrahedron model of clinical judgment.

The tetrahedron model of clinical judgment (Rock, Bransford, Maisto, and Morey, Clin. Psychol. Rev. 7:645-661, 1987; Rock, Bransford, Morey, and Maisto, Clin. Psychol. Rev. 8:411-416, 1988) provides a framework for identifying factors that may influence the judgments of psychotherapists (e.g., clinical and counseling psychologists, psychiatrists, social workers, etc). Three parameters of the model were experimentally manipulated: mode of of presentation of clinical information, patient, and judgment task. Sixteen clinical psychology graduate student therapists evaluated two patients on axis I and axis II of the DSM-III. Judgmental accuracy was influenced by main effects and two- and three-way disordinal interactions among the three model parameters. Additionally, we found that judgemental accuracy was positively related to experience and training. This relationship was evident only when experience was assessed with specific rather than general measures, and when the clinical materials were presented in an audiovideo format and hence resembled the conditions under which the clinicians in the study acquired that training and experience. Implications for the design of training programs that facilitate competency in clinical judgment are discussed.

Physician and practice characteristics associated with judgments about breast cancer treatment.

Since most cancer is treated in the local community, the judgments of primary care physicians about treatment of breast cancer are important. This study examined physician and practice characteristics associated with physician judgments about the treatment of Stage I and Stage II breast cancer. Data are combined from samples of 3,436 physicians: physicians affiliated with hospitals participating in the Community Clinical Oncology Program (CCOP) and a national sample of non-CCOP physicians. This study focused on 1,460 physicians who had seen breast cancer patients and participated in treatment decision-making. Judgments were elicited using brief vignettes. Judgments were more variable for Stage I than for Stage II treatments. Judgments consistent with the NIH Consensus Conferences on breast cancer were more likely from surgeons, physicians who participated in information networks focused on cancer, and those with more breast cancer patients. Concurrence with the consensus conference positions was less likely in older physicians and those in solo practice. These findings point to structures that reinforce quality of care, particularly those that enhance communication, such as group practice or the activities of hospital staffs, information networks, and organized continuing education.

Old fashion clinical judgment in the era of protocols: is mandatory chest X-ray necessary in injured patients?

BACKGROUND: The ATLS Course advocates that injured patients have a chest x-ray (CXR) to identify potential injuries. The purpose of this study was to correlate clinical indications and clinician judgment with CXR results to ascertain if a selective policy would be beneficial. METHODS: Patients treated at a Level I trauma center over 12 months were prospectively evaluated. Before obtaining a CXR, signs, symptoms, and history suggestive of thoracic injury were identified. Additionally, a trauma surgeon (TS) recorded whether in their judgment a CXR was clinically indicated. These findings were compared with final CXR diagnoses. The sensitivity of individual clinical indicators, combinations of clinical indicators, and TS judgment for CXR abnormalities were calculated with a 95% confidence interval. RESULTS: During the twelve-month study period, data were acquired on 772 patients (age 0-102 years). Seventy percent were male and 86.0% were injured by blunt force. Only 29% (N = 222) of the patients manifested one or more of the clinical indicators (signs and symptoms). The negative predictive value for the TS judgment was 98.2% which was superior to the clinical indicators. Reliance on the opinion of the TS to determine the need for a CXR would have eliminated 49.9% of CXRs and avoided hospital and radiologist reading charges totaling $100,078.22. CONCLUSION: Mandatory CXR for all trauma patients has a low yield for abnormal findings. A selective policy relying on surgical judgment guided by clinical indicators is safe and efficacious while reducing cost and conserving resources.

Clinical judgment in rheumatoid arthritis. IV. Rheumatologists' assessments of disease remain stable over long periods.

Seven rheumatologists made judgments about the improvement or deterioration of identical sets of 50 'paper' patients on two occasions one year apart. The stability of their judgments over one year (rs = 0.70) compared favourably with the reliability of duplicate judgments on each occasion (rs = 0.76). Multiple regression analysis of the patient data in relation to the disease assessments provided a model of each clinician's underlying judgment policy. The stability of judgments predicted by these policy models was even higher (rs = 0.83).

Acoustic analyses support subjective judgments of vocal emotion.

Subjective human judgments of emotion in speech have been considered to be less reliable than acoustic analyses in scientific studies, but acoustic analyses have had limited ability to detect subtle vocal nuances that give useful social information about human intent and meaning to discourse partners. Two post hoc analyses were undertaken to determine if results from acoustic analyses of vocalizations were related to subjective judgments of vocal affect (affective prosody). Acoustic analyses of fundamental frequency (F(o)) and subjective judgments of emotional content of vocal productions from two studies underwent statistical analyses: Study 1-vocal repetition of sentences using 6 basic emotions in 24 detoxified alcoholics and 15 controls; study 2-quality/quantity of "motherese" speech directed to 52 infants in Cambridge, England. Ratings of emotion indicators for both studies were done by female researchers of different ages and cultural/language backgrounds. In both studies, acoustic analyses of F(o) elements in utterances accounted for approximately 50% of the effect when modeling subjective emotion accuracy and emotion intensity ratings, using linear regression analyses. Acoustic analyses of F(o) are positively associated with subjective judgments of emotion indicators, and speakers who cannot vary F(o) are unable to convey emotion accurately to communication partners. Yet acoustic analyses are limited in comparison to the exquisite complexity of the human auditory and cognitive systems. Subjective judgments of emotional meaning in speech can be a reliable variable in scientific inquiry and can be used for more complex, subtle studies of speech communication and intentionality than acoustic analyses.

Double-judgment psychophysics: problems and solutions.

Many paradigms for comparing identification thresholds with detection thresholds require the observer to make double judgments. We show that these paradigms can produce misleading results because of response biases and attentional shifts. For example, the subject's response bias plus correlated noise can mimic inhibition between channels. Some of these same problems can affect single-judgment paradigms. A detailed analysis of the double-judgment forced-choice paradigm reveals that there are a multiplicity of optimal strategies, some of which enhance identification over detection. Several improved analysis techniques for minimizing the effects of cognitive factors are proposed for both the double-judgment forced-choice paradigm and the double-judgment rating-scale paradigm. A classification scheme for distinguishing different types of interactions and correlations is developed. When the new rating-scale algorithm is applied to the detection of well-separated spatial frequencies, substantial masking but negligible inhibition is found. The rating-scale paradigm is shown to be useful in revealing not only the sensitivity and the interactions of the underlying mechanisms but also the observer's information-processing strategies.
