Hemispheric activation, affective judgments, and pain perception.

This study utilized a unique contact lens method to examine the influence of right hemisphere processing on affective judgments and pain perception. Under conditions of unilateral visual stimulation, participants completed affective ratings of films and underwent a cold pressor pain task. The goal was to examine differences in affective judgments of films projected to one or the other hemisphere and to examine the influence of this unilateral visual stimulation on pain sensitivity. The results failed to replicate a previous finding of differential affective judgments under conditions of right and left visual stimulation. Nonetheless, in female subjects, unilateral visual stimulation was significantly associated with pain lateralization. This finding is discussed in terms of attentional processes in pain perception and limitations of the current lens design.

Spatial judgments with monoscopic and stereoscopic presentation of perspective displays.

Spatial judgments with monoscopic and stereoscopic presentation of perspective displays were investigated in the present study. The stimulus configuration emulated a visual scene consisting of a volume of airspace above a ground reference plane. Two target symbols were situated at various positions in the space, and observers were instructed to identify the relative depth or altitude of the two symbols. Three viewing orientations (15, 45, or 90 deg elevation angle) were implemented in the perspective projection. In the monoscopic view, depth cues in size, brightness, occlusion, and linear perspective were provided in the format. In the stereoscopic view, binocular disparity was added along the line of sight from the center of projection to reinforce the relative depth in the visual scene. Results revealed that spatial judgments were affected by manipulation of the relative spatial positions of the two target symbols and by the interaction between relative position and viewing orientation. The addition of binocular disparity improved judgments of three-dimensional spatial relationships, and the enhancement was greater when monocular depth cues were less effective and/or ambiguous in recovering the three-dimensional spatial characteristics.

Agreement in personality judgments within and between nonoverlapping social groups in collectivist cultures.

The social context hypothesis states that people behave differently in different social groups because group norms and context-specific interpersonal relationships uniquely affect behavior. Consequently, a person who is a member of different, nonoverlapping social groups (i. e., the members of different groups are unacquainted) should be judged consensually on personality traits within each group; however, between groups there should be less agreement in judgments. This research focused on cultural moderation of the social context effect in two collective cultures (China and Mexico) with different norms for interpersonal relationships. Among Chinese, there was greater consensus in trait judgments within groups than between groups, whereas in Mexico, agreement within and between groups was equivalent. Culturally based relationship norms that affect cross-context consistency of behavior and, in turn, the consistency of trait judgments across groups were described.

A validity study of expert judgment procedures for setting cutoff scores on high-stakes credentialing examinations using cluster analysis.

This study compares an expert judgment process--minimal performance levels (MPL) using the Nedelsky and Ebel procedures--for setting cutoff scores for pass/fail on licensure examinations with an empirical approach--cluster analysis. Data from all three components of the Canadian Standard Assessment in Optometry (CSAO) examinations (knowledge, clinical judgment, and clinical skills) from 243 candidates were obtained. Results indicate that for the written components of the exams employing the Nedelsky method of MPL setting, there was a mean agreement of pass/fail of 81% with the cluster analysis approach on pass/fail categorization. For the performance exams using the Ebel method, the mean agreement of pass/fail with the cluster analysis was 93%. Thus the subjective approaches to setting cutoff scores (i.e., expert judgment methods) converge with the objective method (i.e., cluster analysis) of classifying test takers in the same categories.

A comparison of knowledge, synthesis, and clinical judgment. Multiple-choice questions in the assessment of physician competence.

This study compares the reliability, validity, and efficiency of three multiple-choice question (MCQs) ability scales with patient management problems (PMPs). Data are from the 1980, 1981, and 1982 American Board of Internal Medicine Certifying Examinations. The MCQ ability scales were constructed by classifying the one best answer and multiple-true/false questions in each examination as measuring predominantly clinical judgment, synthesis, or knowledge. Clinical judgment items require prioritizing or weighing management decisions; synthesis items require the integration of findings into a diagnostic decision; and knowledge items stress recall of factual information. Analyses indicate that the MCQ ability scales are more reliable and valid per unit of testing time than are PMPs and that clinical judgment and synthesis scales are slightly more correlated with PMPs than is the knowledge scale. Additionally, all MCQ ability scales seem to be measuring the same aspects of competence as PMPs.

Importance of expert judgment in content-related validity evidence.

The unified conceptualization of validity with regard to content-related evidence has been expressed succinctly by the authors of the Standards for Educational and Psychological Testing (AERA et al., 1985): Content-related evidence of validity is a central concern during [instrument] development, whether such development occurs in a research setting, in a publishing house, or in the context of professional practice. Expert professional judgment should play an integral part in developing the definition of what is to be measured, such as describing the universe of content, generating or selecting the content sample, and specifying the item format and scoring system. Thus, inferences about content are linked to [instrument] construction as well as to establishing evidence of validity after [an instrument] has been developed and chosen for use. (p. 11) This article has demonstrated the process of collecting content-related validity evidence in terms of the specific requirements of the Standards. Five standards were identified and interpreted according to the initial stages of instrument construction: domain specification, item development, and item, subscale, and scale content validation. The role of expert judgment during these stages and the variety of evidence that can be gathered were described. For most instruments, the review process would necessitate two meetings of 1 to 2 hours each to review the domain specifications and another two meetings to determine the match between the items and the specifications. The importance of these 8 hours or whatever additional time is needed to obtain the validity evidence was emphasized. Finally, an application of the Standards was provided to illustrate step-by-step how the judgmental review process can be planned and executed.

Judgment analysis of surgeons' prioritization of patients for elective general surgery.

BACKGROUND: Access to elective general surgery in New Zealand is governed by clinicians' judgment of priority using a visual analog scale (VAS). This has been criticized as lacking reliability and transparency. Our objective was to describe this judgment in terms of previously elicited cues. METHODS: We asked 60 general surgeons in New Zealand to assess patient vignettes using 8 VAS scales to determine priority. They then conducted judgment analysis to determine agreement between surgeons. Cluster analysis was performed to identify groups of surgeons who used different cues. Multiple regression for the combined surgeons was undertaken to determine the predictability of the 8-scale VAS. RESULTS: Agreement between surgeons was poor (ra=0.48). The cause of poor agreement was mostly due to poor consensus (G) between surgeons in how they weighted criteria. Using cluster analysis, we classified the surgeons into 2 groups: 1 took more account of quality of life and diagnosis, whereas the other group placed more weight on the influence of treatment. The 8-scale VAS showed good predictability in assigning a priority score (R2=0.66). DISCUSSION: The level of agreement reflects surgeons' practice variation. This is exemplified by 2 distinct surgeon groups that differ in how criteria were weighted.

Clinical utility of the judgment of line orientation test and facial recognition test in children with acquired unilateral cerebral lesions.

In unselected adult patients with brain damage, the Judgment of Line Orientation Test and the Facial Recognition Test are considered valid instruments for detecting right cerebral hemisphere lesions. It is unknown, however, whether this applies to children as well. Performance levels on the Judgment of Line Orientation Test and the Facial Recognition Test of 18 children with acquired left cerebral lesions and 14 children with acquired right cerebral lesions were reviewed. Subjects were unselected for age, sex, or etiology. Age-related norms were obtained in 81 normal controls, aged 7 to 14 years. Judgment of Line Orientation Test and Facial Recognition Test performance levels did not predict the presence of cerebral pathology per se in our unselected groups with demonstrated unilateral cerebral lesions, nor did they contribute to the prediction of the side of the lesion within the two groups with cerebral lesions. These results cast serious doubt on an important aspect of the clinical utility of both tests in children, namely their discriminative validity in the assessment of etiologically unselected populations with brain damage.

Predicting clinical judgment for a primary grade apperception battery.

A six-card Primary Grade Apperception Battery (three cards from the CAT and three from the SAM) was administered to one group of first grade children on a 4 month test-retest schedule and to a new group of first graders 1 year later. Two clinical psychologists read the protocols and made clinical judgments regarding home and school adjustment on a four-point scale. An initial regression formula to predict clinical judgment from objective apperception score data was derived. The formula was validated on the retest data and the new sample. The results indicate the derived apperception score reliably predicted clinical judgment. In general, the results also suggest the six card apperception battery may be a useful screening test for school and home adjustment for first and second grade children.

Sex and sexual orientation: the effect of group membership on individuals' judgments about self and others' HIV risk.

No previous study has directly compared homosexual and heterosexual men and women's perceptions of HIV risk. In fact, empirical research focusing on homosexual women's perception of HIV risk is scarce. This paper, therefore, examines whether homosexual and heterosexual women and men (N = 60) make varied self and other (peer and non-peer) HIV risk judgments. The paper also examines the roles of motivational (health anxiety) and cognitive (HIV knowledge) factors in relation to HIV risk judgments. The results show that each group held different perceptions of risk for various "other" groups. Only homosexual men showed evidence for an optimistic bias, whereas homosexual women showed evidence of realistic perceptions. Both cognitive and motivational factors were shown to be associated with risk judgments for homosexual women and heterosexual men. Methodologically the use of Multidimensional scaling as an analytic strategy is recommended.

Judgments of the rule-related behaviour of health care professionals: An experimental study.

OBJECTIVES: To explore the judgments of rule-related behaviour by health care professionals and the general public in the UK, against a background in which clinical guidelines and protocols are proliferating. DESIGN: A questionnaire survey was used in which short scenarios describing medical practice were presented to a sample of health care professionals and members of the general public. METHODS: The health care sample consisted of 315 nurses, doctors and midwives from three English National Health Service (NHS) Trusts who volunteered to take part in the study. A stratified sample of members of the general public (N = 350) was recruited via a market research organization. Three types of behaviour (compliance with a protocol, violation of a protocol, and improvization, where no protocol exists) and three types of outcome for the patient (good, bad, poor) were manipulated within nine scenarios. Respondents were asked to make judgments about (1) the inappropriateness of behaviour (2) likelihood that they would take further action and (3) responsibility for the outcome. RESULTS: Findings suggest that the process of care has a greater effect on judgments of the behaviour of health care professionals than does the outcome of that behaviour. This was equally true of the professional and public samples. CONCLUSIONS: The study has both theoretical and practical implications. First, information about a behaviour's relationship to existing rules has a stronger influence than the consequence of the behaviour on attributions of responsibility. Secondly, using clinical protocols as a way of managing risk in the NHS may be counterproductive unless full compliance is achieved.

Teacher judgments of student reading interests: how accurate are they?

This study investigated the factors used by teachers of the hearing impaired in identifying the reading interests of their students. It also examined the accuracy of their judgments in comparison to students' responses on a reading interest inventory. Twenty teachers of the hearing impaired were asked to judge the top two reading interest areas for each of the 82 students. They also described the factors they used in making their judgments. The 82 hearing-impaired students completed a reading interest inventory. Their results were compared then with their teachers' judgments. Results indicated that teachers were only moderately accurate in judging their students' reading interests.

Lightness and brightness judgments of coplanar retinally noncontiguous surfaces.

Several experiments reveal that judgments of lightness and brightness of an achromatic surface depend, in part, on the luminances of other surfaces perceived to share the same depth plane, even if the surfaces are well separated on the retina. Two Mondrians, simulated on a CRT, were viewed through a haploscope. The more highly illuminated Mondrian contained a comparison patch and appeared nearer than the more dimly illuminated Mondrian, which contained the test patch. By independently varying the disparity of the test patch, observers could make the test patch appear to be in the depth plane of either the dimly or the highly illuminated Mondrian. Observers set the luminance of the test patch to match that of the comparison patch. The test was set as high as 15% more luminous when it was perceived in the depth plane of the highly illuminated rather than the dimly illuminated Mondrian. Both brightness and lightness judgments were affected by the perceived depth of the test, although the lightness judgments of inexperienced observers sometimes were dominated by local-contrast matching.

Influence of variations in edge blur on minimally distinct border judgments: a theoretical and empirical investigation.

Minimally distinct border (MDB) settings were made for white-chromatic borders that varied from 1 to 32 arcmin in the space constant of Gaussian blur. The spectral characteristics, additivity, and variability of the MDB judgments remained essentially unchanged across all degrees of edge blur up to and including a space constant of 8 arcmin. For space constants of 16 and 32 arcmin, the variability of the settings increased dramatically, but no consistent trends toward changes in spectral characteristics or additivity were found. Predictions of visual response to edge blur were derived from Wilson and Gelb's six-channel model of spatial vision [J. Opt. Soc. Am. A 1, 124 (1984)]. The fits of these calculations to the data suggest that either a single low- to mid-spatial-frequency-tuned channel mediates MDB judgments over a wide range of variations of edge blur or else the channels that jointly mediate these judgments are importantly similar in their chromatic characteristics.

Frames of reference for the display of battlefield information: judgment-display dependencies.

In 2 experiments, U.S. Army soldiers viewed computer-generated displays that presented battlefield information from 3 different frames of reference: a 2D plan view display (with contour lines), a 3D exocentric perspective display, and an interactive 3D immersed display. In Experiment 1, soldiers made geographical judgments. The results suggested that both 3D displays suffered from ambiguity of distance estimates but that the 3D immersed display was most accurate for judging whether a location is directly visible from another. In Experiment 2, the 3D exocentric display was compared with a 3D immersed view, coupled with a small 2D inset map, in a more continuous battlefield scenario in which judgments of enemy activity were made. The findings of 3D ambiguity were replicated from Experiment 1. The accuracy of judgments of enemy activity suffered with the immersed display when information necessary to answer correctly did not appear in the initial forward view and required panning to acquire, reflecting the cognitive demands of integration across different views. This display also hindered soldiers' ability to report changes in enemy activity from one scene to the next. The results of this research will help to provide guidelines for the appropriate choice of computer display technology to assist in designing battlefield visualization aids. Caution should be exercised in choosing immersive viewpoints.

Area of depictions versus insufficient transformations in volume judgments.

Two hypotheses about judgments of apparent volume of depicted objects were compared. One hypothesis was that the area of the depiction influences judgments. The alternative was that volume judgments are based on an incomplete transformation from the two-dimensional stimulus to the object "implied" by the drawing. 38 college undergraduates ranked 24 drawings of rectangular boxes according to apparent volume. Results strongly supported the incomplete transformation hypothesis.

Association of need for cognition with judgments of height, weight, and body fat covariation.

559 college students, assessed for Need for Cognition, judged whether height, weight, and body fat were correlated using judgment probes that controlled for framing and conditional format. A principal components analysis of Need for Cognition scores identified two factors underlying the scale, which may be important in judgment outcome. In addition, judgments about correlations among height, weight, and body fat were similar to those of previous studies. Furthermore, the hypothesis that Need for Cognition would be related to the tendency to judge a negative correlation between height and body fat, i.e., a possible illusory correlation, was confirmed. Results are discussed relative to the Elaboration Likelihood Model of Persuasion.

Visual influences on auditory pluck and bow judgments.

In the McGurk effect, visual information specifying a speaker's articulatory movements can influence auditory judgments of speech. In the present study, we attempted to find an analogue of the McGurk effect by using nonspeech stimuli--the discrepant audiovisual tokens of plucks and bows on a cello. The results of an initial experiment revealed that subjects' auditory judgments were influenced significantly by the visual pluck and bow stimuli. However, a second experiment in which speech syllables were used demonstrated that the visual influence on consonants was significantly greater than the visual influence observed for pluck-bow stimuli. This result could be interpreted to suggest that the nonspeech visual influence was not a true McGurk effect. In a third experiment, visual stimuli consisting of the words pluck and bow were found to have no influence over auditory pluck and bow judgments. This result could suggest that the nonspeech effects found in Experiment 1 were based on the audio and visual information's having an ostensive lawful relation to the specified event. These results are discussed in terms of motor-theory, ecological, and FLMP approaches to speech perception.
