Detecting faking on the Rorschach: computer versus expert clinical judgment.

In a previous study of the ability of expert Rorschach interpreters to detect faking that used true and malingered protocols, the experts faired very poorly. In this study, 50% of these same protocols were scored by the Exner system and analyzed by Exner's Semantic Computer Interpretation program. The program indicated invalidity of protocols only on the basis of low R and designated the faked protocols high on psychotic descriptors, barely indicating psychosis for the true schizophrenic protocols. Unlike the judges, however, the computer gave no psychotic designation to the normal protocols. The scoring-computer analysis method was as susceptible to faking as were the clinical judgments.

Judgments of deservingness: studies in the psychology of justice and achievement.

This article presents a review and conceptual analysis of the concept of deservingness that incorporates the effects of personal values, perceived responsibility, ingroup-outgroup relations, and like-dislike relations. Selected studies show that reactions to another's success or failure and to the rise or fall of "tall poppies" or high achievers depends on the degree to which the positive or negative outcome is seen to be deserved; that individual differences in personal values and in value syndromes may be assumed to affect deservingness via the subjective values assigned to actions and outcomes; that group membership, status, interpersonal liking-disliking, and perceived moral character also affect judgments of deservingness; and that deservingness is a key variable that mediates how observers react to penalties imposed on the perpetrators of different kinds of offense. It is argued that the inclusion of deservingness goes beyond approaches in which perceived responsibility is accorded central status by adding a further link in the causal chain, thus enabling a more complete consideration of the effects of justice and value variables on how people react to positive and negative outcomes for both self and other.

Line bisection judgments implicate right parietal cortex and cerebellum as assessed by fMRI.

OBJECTIVE: To use functional MRI (fMRI) to determine which brain regions are implicated when normal volunteers judge whether pretransected horizontal lines are correctly bisected (the Landmark test). BACKGROUND: Manual line bisection and a variant thereof involving perceptual judgments of pretransected lines (the Landmark test) are widely used to assess unilateral visuospatial neglect in patients with neurologic disease. Although unilateral (left) neglect most often results from lesions to right temporoparietal cortex, the normal functional anatomy of the Landmark test has not been convincingly demonstrated. METHODS: fMRI was carried out in 12 healthy right-handed male volunteers who judged whether horizontal lines were correctly prebisected. In the control task, subjects detected whether the horizontal lines contained a transection mark irrespective of the position of that mark. Response was by two-choice key press: on half the trials, subjects used the right, and on half, the left hand. Statistical analysis of evoked blood oxygenation level-dependent responses, measured with echoplanar imaging, employed statistical parametric mapping. RESULTS: Performing the Landmark task showed neural activity (p < 0.05, corrected) in the right superior posterior and right inferior parietal lobe, early visual processing areas bilaterally, the cerebellar vermis, and the left cerebellar hemisphere. Only the latter area showed a significant interaction with hand used. CONCLUSIONS: The right hemispheric dominance observed in inferior parietal cortex is consistent with the results of lesion studies. Right superior parietal cortex, vermis, and left cerebellar hemisphere have not been implicated in neglect, but all appear to play a cognitive role in the Landmark task.

Age variations in judgments of 'great' art works.

This paper reports the results of two large-scale surveys concerning nominations of 'greatness' in the arts. In Study 1, 1088 respondents to a national newspaper survey nominated the greatest art works of the past 1000 years. Analyses indicated that there was some, albeit limited, evidence that older respondents nominated older art works, but no evidence of a tendency to nominate works produced during the participants' adolescence/early adulthood. In Study 2, a very brief questionnaire distributed through a CD retail chain, a national newspaper, and a national TV station asked 12,502 participants to nominate up to three of the greatest pop musicians of all time. Analyses indicated a tendency to nominate musicians who were successful while the participants themselves were in adolescence/early adulthood. These results are discussed in terms of the extent to which age can explain judgments of artistic 'greatness' within different art forms.

A meta-analysis of sex differences in romantic attraction: do rating contexts moderate tactic effectiveness judgments?

Although a number of studies have explored perceived sex differences in romantic attraction effectiveness, no research has systematically examined whether different rating contexts might moderate effectiveness judgments. In a meta-analytic review of romantic attraction research, four potential moderating variables were examined: temporal context (unspecified, long-term, short-term), manipulation form (self-promotion, competitor derogation), attraction type (general, retention, poaching), and sex of rater (mixed, same, opposite). Although perceived sex differences in physical appearance and resource-related tactics remained stable across most moderating variables, sex differences did vary across some rating contexts. For example, perceptions of sex differences in the effectiveness of appearance-related attraction tactics were much stronger in the context of self-promotion (d = -.77) compared with the competitor derogation context (d = -.17). Resource-related tactics of attraction displayed the opposite pattern, with significantly larger perceived sex differences in the context of competitor derogation (d =.93) than in self-promotion (d =.68). Discussion focused on the implications of sex difference variability and stability across rating contexts for evolutionary theories of romantic attraction.

Evaluation of clinical judgment in the identification and treatment of nosocomial pneumonia in ventilated patients.

To evaluate the accuracy of clinical judgment in the diagnosis and treatment of nosocomial pneumonia in ventilated patients, we studied 84 patients suspected of having nosocomial pneumonia because of the presence of a new pulmonary infiltrate and purulent tracheal secretions. We prospectively evaluated the accuracy of diagnostic predictions and therapeutic plans independently formulated by a team of physicians aware of all clinical, radiologic and laboratory data, including the results of Gram-stained bronchial aspirates. Definite (n = 51) or probable (n = 33) diagnoses could be established in all patients by strict histopathologic and/or bacteriologic criteria. Only 27/84 patients were diagnosed as having pneumonia. Organisms responsible for pneumonias were identified by quantitative cultures of samples obtained using a protected specimen brush or pleural fluid cultures. Four hundred eight predictions were made for the 84 studied patients. Clinical diagnoses for patients subsequently diagnosed as having pneumonia were accurate in 81/131 cases (62 percent). Furthermore, only 43/131 (33 percent) therapeutic plans proposed for these patients represented effective therapy. Common causes of inappropriate treatment included failure to diagnose pneumonia (50 plans), failure to effectively treat highly resistant organisms (21 plans), and failure to treat all organisms in cases of polymicrobial pneumonia (14 plans). Therapeutic plans formulated for patients without pneumonia included the unnecessary use of antibiotics in 45/277 cases (16 percent). These findings indicate that the use of clinical criteria alone does not permit the accurate diagnosis of nosocomial pneumonia in ventilated patients, and commonly results in inappropriate or inadequate antibiotic therapy for these patients.

Role of clinical judgment in the application of a nucleic acid amplification test for the rapid diagnosis of pulmonary tuberculosis.

BACKGROUND: Several nucleic acid amplification (NAA) tests for Mycobacterium tuberculosis (MTB) have been licensed for the rapid diagnosis of active pulmonary tuberculosis (PTB) in respiratory secretions. There is uncertainty however regarding the practical application of these tests in clinical decision making. OBJECTIVE: To evaluate the utility of the COBAS AMPLICOR assay (Roche Diagnostics; Singapore) for MTB as applied by specialists for the rapid diagnosis of PTB in the routine clinical setting. DESIGN: A prospective study of consecutive patients suspected of PTB and tested with the AMPLICOR assay under the care of respiratory physicians. The final diagnosis was based on all relevant clinical information after at least 3 months of follow-up. Accuracy of the NAA test was compared with that of the initial expectant treatment. Expectant treatment was based on an integrated approach that incorporated clinical evaluation with results of direct smear and NAA tests. RESULTS: The incidence of PTB in 168 patients was 32%. The basis for expectant treatment of PTB was positive smear result in 47%, clinical suspicion in 26%, and positive AMPLICOR result in 23%. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the AMPLICOR test were 77%, 100%, 99%, 90%, and 93%, respectively. In comparison, they were 96%, 97%, 94%, 98%, and 97%, respectively, for the integrated clinical approach. CONCLUSIONS: In the rapid diagnosis of PTB, the clinical judgment of specialists augmented the utility of the NAA test: (1) specialists selected patients with high-to-moderate pretest probabilities, (2) they commenced treatment promptly on a positive NAA test result, and (3) they were willing to start treatment in some patients on the basis of high clinical suspicion despite negative smear and negative NAA test results.

Judgments of azimuth and elevation as a function of monoscopic and binocular depth cues using a perspective display.

The purpose of this study was to investigate the use of three-dimensional display formats for judgments of spatial information using an exocentric frame of reference. Eight subjects judged the azimuth and elevation that separated two computer-generated objects using either a perspective or stereoscopic display. Errors, which consisted of the difference in absolute value between the estimated and actual azimuth or elevation, were analyzed as the response variable. The data indicated that the stereoscopic display resulted in more accurate estimates of elevation, especially for images aligned approximately orthogonally to the viewing vector. However, estimates of relative azimuth direction were not improved by use of the stereoscopic display. Furthermore, it was shown that the effect of compression resulting from a 45-deg computer graphics eye point elevation produced a response bias that was symmetrical around the horizontal plane of the reference cube, and that the depth cue of binocular disparity provided by the stereoscopic display reduced the magnitude of the compression errors. Implications of the results for the design of spatial displays are discussed.

Comparison of Nasometer and listener judgments of nasality in the assessment of velopharyngeal function after pharyngeal flap surgery.

This study examined the relationship between nasalance scores as derived from the Model 6200 Nasometer and listener judgments of perceived nasality for individuals with pharyngeal flaps. Sixteen individuals with pharyngeal flaps read a speech sample consisting of seven sentences for which associated nasalance scores were obtained. In addition, 10 trained listeners were asked to judge the subjects' audiorecorded speech samples for the degree of both hypernasality and hyponasality using two 6-point scales. The mean judges' ratings of hypernasality did not increase systematically with increasing nasalance scores or with decreasing hyponasality ratings. However, as the nasalance scores associated with nasal loaded sentences increased, a systematic decrease in listener perception of hyponasality occurred.

Observer agreement, credibility, and judgment: some considerations in presenting observer agreement data.

Graphical and statistical indices employed to represent observer agreement in interval recording are described as "judgmental aids", stimuli to which the researcher and scientific community must respond when viewing observer agreement data. The advantages and limitations of plotting calibrating observer agreement data and reporting conventional statistical aids are discussed in the context of their utility for researchers and research consumers of applied behavior analysis. It is argued that plotting calibrating observer data is a useful supplement to statistical aids for researchers but is of only limited utility for research consumers. Alternatives to conventional per cent agreement statistics for research consumers include reporting special agreement estimates (e.g., per cent occurrence agreement and nonoccurrence agreement) and correlational statistics (e.g., Kappa and Phi).

Study of Graves design Judgment Test and Barron-Welsh Revised Art Scale.

Previous research suggests that scores on both the Graves Design Judgment Test and the Barron-Welsh Revised Art Scale correlate with education in art and with aspects of creativity but have little validity with respect to artistic performance. With a heterogeneous group of 48, the Graves test correlated significantly with fine-arts education, interest in the arts, artistic achievement, and creative independence. The Barron-Welsh scale correlated significantly with only fine-arts education in a similar group of 47.

Hemisphere differences and judgments of simultaneity of brief light flashes.

A series of experiments was conducted to investigate the possibility of hemispheric specialization for judgments of the simultaneity of two light flashes. Right-handed subjects adjusted two light flashes until they appeared simultaneous. The comparison of measures derived from the two possible orders of the light flashes suggested that the right hemisphere of right-handed subjects performed the function of ordering visual stimuli in time. Two further experiments examined an alternative explanation, that of a left-to-right scanning mechanism, the results of which also suggested a hemisphere explanation. The results of these experiments are discussed in terms of previous research and theories which located a temporal ordering mechanism in the speech hemisphere.

Binocular pattern stabilization by afterimage technique: reliability of children's time-dependent judgments of chromatic features.

To investigate visual afterimage technique as a means of producing retinally stabilized pattern, children's judgments of time-dependent shifts in chromatic appearance of random-dot configurations were twice examined within a 3-wk. interval. 13 subjects, aged 7 to 12 yr., were very consistent (r = .93) in their test-retest response times. This supports the belief that after image procedures can be developed as a reliable means of studying developmental aspects of stabilized pattern perception.

The axis feature: illusionary effects on children's judgments of length.

The effect of the position of lines on length estimation was investigated. 40 5-yr.-olds were asked to compare the two arms of an L-shaped figure presented inside circular frames of different diameters. For each figure one of the arms was on the axis, that is, the diameter, and the other arm was perpendicular to that axis. In making perceptual judgments about the relative length of two lines the children tended to describe the on-axis line as longer than the off-axis line. This illusion which, presumably, reflects a perceptual force induced by the characteristics of the structural pattern, supports the context model of visual anomalies.

Effects of laterality and visual angle on time judgments: a phenomenological investigation of time durations.

20 students from an undergraduate class participated in an experiment designed to study the effects of laterality and visual angle on time judgments. Using a standard two-field tachistoscope , subjects were exposed to two experimental conditions, (1) stimulus cards with a single red or blue dot in the center and several dots clustered on both sides near the center and equidistant from it (visual angle of .6 degrees) and (2) stimulus cards with a single red or blue dot in the center and several dots clustered on both sides away from the center on the edge of the card (visual angle of 2.6 degrees). Five cards containing a single red or blue dot were used to control for response bias. The subjects were asked to indicate whether they saw dots in the left, right, or both fields, and whether they perceived a time duration between fields. No difference in time duration existed, however, as all cards were exposed to both fields for equal durations. The predictions that the judged duration of dot patterns would be more accurate favoring the left visual-field and more accurate where the distance between the point of fixation and stimulus was larger were supported.

Children's judgments of televised events: the real versus pretend distinction.

Previous research suggests that children's understanding that television is fictional may be dependent on various factors inherent in televised events. 36 children, 4- to 6-yr.-old, were asked to judge the reality of specific televised events shown via videotape. The events varied in aggressiveness, format, and type of character shown. While age and sex differences were absent, children's judgments were dependent on the format of the televised events (cartoon versus noncartoon) rather than other variables. Implications for research on children's learning of televised aggression and prosocial behaviors are discussed.
