Mood and judgment: the affect infusion model (AIM).

Evidence for the role of affective states in social judgments is reviewed, and a new integrative theory, the affect infusion model (AIM), is proposed as a comprehensive explanation of these effects. The AIM, based on a multiprocess approach to social judgments, identifies 4 alternative judgmental strategies: (a) direct access, (b) motivated, (c) heuristic, and (d) substantive processing. The model predicts that the degree of affect infusion into judgments varies along a processing continuum, such that judgments requiring heuristic or substantive processing are more likely to be infused by affect than are direct access or motivated judgments. The role of target, judge, and situational variables in recruiting high- or low-infusion judgmental strategies is considered, and empirical support for the model is reviewed. The relationship between the AIM and other affect-cognition theories is discussed, and implications for future research are outlined.

Consistency of physician judgments of capacity to consent in mild Alzheimer's disease.

OBJECTIVE: To investigate the agreement of physician judgments of capacity to consent to treatment for normal and demented older adults. DESIGN: Subjects were individually administered a standardized consent capacity interview. Physicians viewed videotapes of these interviews and made judgments of capacity to consent to treatment. SETTING: University medical center. PARTICIPANTS: Subjects assessed for competency (N = 45) were 16 normal older controls and 29 patients with mild Alzheimer's disease (AD). Five medical center physicians with experience assessing the competency of dementia patients were recruited from the specialties of geriatric psychiatry, geriatric medicine, and neurology. MEASUREMENTS: Subjects were videotaped responding to a standardized consent capacity interview (SCCI) designed to evaluate capacity to consent to treatment. Study physicians blinded to subject diagnosis individually viewed each SCCI videotape and made a judgment of competent or incompetent to consent. Agreement of physician judgments was evaluated using percentage agreement, kappa, and logistic regression. RESULTS: Competency judgements of physicians showed high agreement for controls but low agreement for AD patients. Physicians as a group achieved 98% judgment agreement for the controls but only 56% judgment agreement for the mild AD patients. The physician group kappa for controls was 1.00 (P < .0001) and differed significantly (P < .0001) from the physician group kappa of .14 (P = .44) for AD patients, indicative of a real difference in the ability of the study physicians to judge consistently competency across the two groups. Similarly, logistic regression analysis showed significant variability in physician judgements for the AD group (chi 2 = 63.8, P < .0001) but not for the control group (chi 2 = 4.1, P = 1.00). Within the Ad group, pairwise analyses revealed significant judgment disagreement (P < .01) for seven of the 10 physician pairs.

Gradient effects of fundamental frequency on stop consonant voicing judgments.

The post-stop-release rise or fall of fundamental frequency (F0) is known to affect voicing judgments of syllables with ambiguous voice onset times (VOTs). In 1986, Silverman claimed that the critical factor was not direction of F0 change but rather its direction relative to the intonational contour. He further claimed that only F0s that start above and fall to the contour have an effect proportional to the size of the frequency change; F0s that rise to the contour by different amounts were claimed to be equivalent. In our first experiment, we examined the effect on voicing judgments of five onset F0s preceding a single, flat contour. Only falling F0s were differentiated in the first set of judgments, but after increased exposure to the syllables, even F0s below the contour differentially affected the voicing judgment. In a second experiment, the contour of the final part of the syllable was flat, rising or falling. F0 contour affected the judgments, as did onset F0s, but the two factors did not interact, indicating that the onset values were not being judged by reference to the contours. However, the contour which was predicted to result in more voiceless judgments also ended at a higher F0 in the vowel, and another effect of voicing is that the F0 is higher throughout the vowel after voiceless stops. In a third experiment, F0 contours were created to contrast contour and mean F0. The effect of the F0 during the vocalic segment appeared to be attributable to the average F0 rather than the contour. In all three experiments, the F0 onset values contributed to the voicing judgment whether they were above or below the putative intonation contour. The contribution of the lower F0s, while significant, was not as great as that of the higher F0s, which argues for a noncategorical contribution of intonation.

Effects of the Ebbinghaus illusion on different behaviors: one- and two-handed grasping; one- and two-handed manual estimation; metric and comparative judgment.

Many studies have suggested that visually-guided action is largely immune to the effects of several pictorial illusions that strongly influence perceptual judgments. The judgments in these experiments, however, have usually involved comparisons of multiple elements within a display, whereas the visually-guided actions have typically involved a pincer grip directed to only one display element. The three experiments presented here assess the influence of this confound on the perception versus action illusion dissociation. In general, the studies suggest (a) that the confound affects perceptual judgment but not grasping or manual estimation, and (b) that difficult visuomotor tasks are more affected by the Ebbinghaus illusion than easier tasks. In Experiment 1, participants reached for or made judgments about plastic disks placed in the center of the Ebbinghaus illusion display. Some participants reached for or made judgments about only the disk on the right, whereas others reached for or judged both disks simultaneously. A large effect of the illusion was found for grasping and comparative judgment, but not for manual estimation or metric judgment. In Experiment 2, the disks were elevated slightly to make gripping the targets easier, and the effects of the illusion on grasping were greatly reduced. For Experiment 3, participants performed the manual estimation task while the hands were placed in view, on the surface of the table, and the effects of the illusion were significantly increased. Taken together, the experiments indicate that task difficulty and hand visibility affect whether a task will be influenced by pictorial illusions or not. One- and two-handed grasping seem to be affected approximately equally.

Lighting position and judgments of distance of shadow-casting objects.

Participants recruited on the web performed in two experiments in which they viewed eight pictures of the same two rods in the exact same positions with shadows generated by a light source located at eight positions around the rods. In Exp. 1, participants judged how much shadows projected to the front, back, and sides of the rods facilitated the correct perception of the actual distance of the rods relative to each other. In Exp. 1 (n: 52), frontal lighting facilitated judgments more than lighting from the rear, but frontal and side lighting did not differ in facilitative effects. In Exp. 2 (n: 72), judgments of rods depicted with shadows were relative to a judgment of the rods depicted without shadows (raw scores were the value of the judgment of the shadowless rods subtracted from the value of the judgment of each of the eight sets of rods). Again, frontal lighting was more facilitative than rear lighting and frontal lighting did not differ from side lighting. However, when the average of each participant's backlighting judgments was compared with his judgment of the shadowless rods, shadows generated by backlighting were more facilitative than none.

Judgments of perceptual groups: reliability and sensitivity to stimulus transformation.

The reliability of subjects' judgments of the groups present in dot patterns and the sensitivity of those judgments to stimulus transformation were assessed. The subjects indicated the groups that they saw within random dot patterns, and each judgment was compared with those of other subjects and with their own judgments for related presentations. Within subjects, each pattern appeared in an initial presentation, an identical repetition, and a transformed state (a rotation or a change in scale). Within-subjects judgments were more reliable than between-subjects judgments. An interpretation of within-subjects results was made in relation to predictions made by a formal algorithm of grouping by proximity (the CODE algorithm), which assumes that grouping by proximity is invariant over transformations such as rotations or changes in scale. A slight cost to transforming the patterns was found. The implications for CODE and for using grouping judgments as data are discussed.

Intersensory conflict between vision and touch: the response modality dominates when precise, attention-riveting judgments are required.

In four experiments, reducing lenses were used to minify vision and generate intersensory size conflicts between vision and touch. Subjects made size judgments, using either visual matching or haptic matching. In visual matching, the subjects chose from a set of visible squares that progressively increased in size. In haptic matching, the subjects selected matches from an array of tangible wooden squares. In Experiment 1, it was found that neither sense dominated when subjects exposed to an intersensory discrepancy made their size estimates by using either visual matching or haptic matching. Size judgments were nearly indentical for conflict subjects making visual or haptic matches. Thus, matching modality did not matter in Experiment 1. In Experiment 2, it was found that subjects were influenced by the sight of their hands, which led to increases in the magnitude of their size judgments. Sight of the hands produced more accurate judgments, with subjects being better able to compensate for the illusory effects of the reducing lens. In two additional experiments, it was found that when more precise judgments were required and subjects had to generate their own size estimates, the response modality dominated. Thus, vision dominated in Experiment 3, where size judgments derived from viewing a metric ruler, whereas touch dominated in Experiment 4, where subjects made size estimates with a pincers posture of their hands. It is suggested that matching procedures are inadequate for assessing intersensory dominance relations. These results qualify the position (Hershberger & Misceo, 1996) that the modality of size estimates influences the resolution of intersensory conflicts. Only when required to self-generate more precise judgments did subjects rely on one sense, either vision or touch. Thus, task and attentional requirements influence dominance relations, and vision does not invariably prevail over touch.

Examination of judgments of drunkenness, binge drinking, and drunk-driving tendencies in teens with and without a family history of alcohol abuse.

BACKGROUND: The present study examined judgment processes of individuals with and without a family history of alcohol abuse. Despite the alarming statistics involving alcohol-related consequences in this population, very little is known about what judgment processes they use or how beneficial these processes are at preventing intoxication and alcohol-related consequences. METHODS: Participants were 270 individuals, 16-18 years old, screened on the basis of the history of family alcohol abuse. Individuals were asked to (1) make judgments of drunkenness in relation to the legal limits in response to factorially manipulated external cues on number of drinks, time taken to consume, and type of beverage, using the methodology of Jaccard and Turrisi (1987), and (2) answer several questions regarding their alcohol-related behaviors. RESULTS: Our results indicated that individuals with a positive family history of alcohol abuse were more likely to make judgmental errors and underestimate their drunkenness relative to individuals without a positive family history of alcohol abuse. Moreover, the errors in judgments were more pronounced in situations involving moderate to heavy alcohol consumption. Finally, family history was found to moderate the relationship between underestimation errors and drinking, and drinking and driving tendencies. For individuals with a positive family history of alcohol abuse, the more they tended to underestimate their drunkenness, the more likely they were to binge drink and drive after drinking. CONCLUSIONS: The findings suggest that judgmental errors tend to be an important process variable in the relationship between family history and alcohol-related behavioral tendencies. The findings are discussed with respect to potential behavioral antecedents (e.g., student binge drinking) and development of prevention programs geared toward training students to make more accurate judgments, using external cues.

Clinical judgment: an ethical issue.

In conclusion, the position of this paper maintains that clinical judgment is a viable, ethical issue of the highest order. Clinical judgment involves the personal orientation, the ethical framework of the one making the decision. Whatever judgment is ultimately made carries with it the burden of the maker's personal ethical approach to life, to the nature of man and finally his approach to the world at large. Clinical judgment is inseparable from ethics. It is further maintained that there must be more research into the areas of clinical judgment in relation to psychiatric nursing research. Clinical specialists, in particular, will be called on to make increasingly complex judgments. They must have a valid method to assist in the formulation, testing and analysis of their decisions. A model must be developed that assists the decision maker in: 1. Objectively identifying and specifying stimul; 2. Controlling and regulating the conditions of the judgment-making-process, intrinsic as well as extrinsic; and 3. Defining and standardizing the conditions of reporting.

[Moral judgment and prediction of criminality. Comparative study of delinquents and non-delinquents].

A group of imprisoned criminals was compared to two groups of not-criminals with regard to five modes of judgment (profile of judgment) measured by Baruk's Tsedek test. The delinquents use more self-interest judgment, social judgment and absence of judgment that the whole of the not-delinquents (significantly different). They more often use the mode of moral judgment than the not-delinquents of the control group (general population) but less often than the not-delinquents of the comparative group (subjects of high educational level and religious for more than half of them). From the profile of judgment obtained for each group, a formula of prediction of tendency to crime was elaborated. It makes it possible to classify with rather good reliability the persons tested in the category of criminals or not-criminals.

Experienced psychiatric nurses' clinical judgments in everyday practices.

The purpose of this study was to explore the characteristics of clinical judgment through uncovering the everyday practices of experienced psychiatric nurses. Participants were 13 nurses and 4 licensed assistant nurses who worked at a private mental hospital. The participants were interviewed and encouraged to describe their everyday practices and clinical judgment episode. The narrative texts were interpreted by the researcher in this study. As a result, the following characteristics emerged: 1) Clinical judgment embedded in everyday practices is based on the experienced nurse's expert ability of knowing the patient and grasping the patient's situation; 2) Clinical judgment is clinical wisdom, including intuition, based on the nurse's experience; 3) Clinical judgment in patient-nurse interactions is strongly affected by closeness/distance in the relationship. Clinical judgment is not context free, rather it is very situational; 4) When group consensus and the nursing care plan exert conformity pressure, the group consensus tends to obstruct the development of an individual nurse's judgment.

Neural response during preference and memory judgments for subliminally presented stimuli: a functional neuroimaging study.

Preexposing subjects to visual stimuli is sufficient to establish a subsequent preference, even when previous exposure is subliminal, such that explicit recognition is at chance. This influence of previous exposure on preference judgments, known as the "mere exposure effect," is a form of unconscious memory. The present functional neuroimaging study examines the mechanism of this effect. Nine volunteer subjects were studied using functional imaging while making forced choice judgments about abstract stimuli on the basis of either preference or memory. Each judgment type was made under two conditions: under one condition one or the other stimulus had previously been presented subliminally, whereas under the second condition both stimuli were novel. Memory judgments were associated with activation of left frontopolar cortex and parietal areas, whereas preference judgments were associated with activation of medial prefrontal cortex and regions of occipital cortex. The modulation of preference by objective familiarity (implicit memory) was associated with right lateral frontal activation. Significant activation of hippocampal gyrus was seen in response to objective stimulus novelty, regardless of judgment type required. Our data thus demonstrate activations of a memory system independent of recollective experience. Dissociable activations within this system implicate a frontopolar involvement in explicit retrieval attempt and right lateral prefrontal cortex involvement in implicit memory expressed in preference judgments. Furthermore, the results suggest that hippocampal response to stimulus novelty can be independent of conscious reportability of familiarity.

Are societal judgments being incorporated into the uncertainty factors used in toxicological risk assessment?

The aim of this paper is to show that the uncertainty factors used in toxic risk assessment to develop exposure standards do contain societal judgments as well as technical judgments. The process generally used today originated in the 1950s, when a deterministic approach to risk was the norm. Technical judgments are required concerning the nature and the quality of the evidence used in the risk assessment. Judgments taken are essentially cautious. This caution may not matter when measured exposure is significantly below the standard and may be accepted when exposure occurs only following an approval process based on "gate keeping." More sophisticated judgments are required when actual exposure may exceed this type of standard or when risk needs to be compared with benefit. These circumstances can occur with patient exposure to human medicines and with occupational exposure to chemicals. Under these circumstances more explicitly considered societal judgments concerning what constitute "broadly acceptable" and "tolerable" risk criteria, and hence what are appropriate uncertainty factors, are required. The outcomes of those societal judgments are likely to vary according to the circumstances surrounding the exposure and have led to smaller uncertainty factors being considered appropriate for occupational exposure, when compared with widespread public exposure.

Cognitive estimation and affective judgments in alcoholic Korsakoff patients.

Alcoholic Korsakoff patients have their most marked deficits in memory, but may exhibit problems in further cognitive and behavioral domains, particularly in so-called frontal lobe functions and on the emotional level. Cognitive estimation is among the frontal lobe-associated functions; nevertheless, the underlying processes of estimation and estimation deficits are still unknown. Additionally, though affective judgments were found to be disturbed in Korsakoff patients one can question whether this result is due to a deficiency in emotional processing itself, or whether deteriorated basic processes underlying all kinds of judgment tasks result in affective judgment errors. In this study, possible relations and underlying cognitive processes of affective and nonaffective judgments (cognitive estimates) were analyzed in a large sample of 39 Korsakoff patients. A neuropsychological test battery was administered together with a new test for cognitive estimation consisting of four dimensions ('size,' 'weight,' 'quantity,' and 'time') and an affective judgment task comprising negative, neutral, and positive words. The Korsakoff patients' results showed marked deficits concerning both, cognitive estimation and affective judgments. These deficits were highly intercorrelated and performance in both tasks was related to basic (e.g., information processing speed) and higher cognitive functions (executive functions and memory), suggesting a common basis in cognitive estimation and in affective judgments in Korsakoff syndrome.

Expert judgment and occupational hygiene: application to aerosol speciation in the nickel primary production industry.

In many situations characterized by sparse data, occupational hygienists have used subjective judgments that are claimed to be derived from their experience and knowledge. While this practice is widespread, there has been no systematic study of 'expert judgment' or the 'art' of occupational hygiene. Indeed, there is a need to address the question of whether there is such a thing as 'expert opinion' in occupational hygiene that is broadly shared by practicing professionals. This research, employing 11 experts who estimate an exposure parameter (the percentages of four nickel species) in 12 workplaces in a nickel primary production industry, provides a large dataset from which useful inferences can be drawn about the quality of expert judgments and the variability among the experts. A well-designed questionnaire that provided succinct information about the processes and baseline data served to calibrate the experts. The Bayesian framework has been used in this work to develop posterior means and standard deviations of the percentages of the four nickel species in the 12 workplaces of interest in the company. These estimates of the nickel speciation are at least as precise as--and most of the time more precise than--those provided by the sparse measurement data. There was a very high degree of agreement among the experts. A majority of the experts agreed among themselves 92% of the time, while almost two-thirds agreed 73% of the time. This, coupled with the fact that the experts came from varied backgrounds, seems to suggest that there is indeed some broad body of specialized knowledge that the experts are drawing on to reach similar judgments. It also seems that one type of expert is not necessarily any better than any other kind, and expertise does not necessarily require intimate familiarity with the workplace. In this example, the expert judgment exercise has indeed enhanced the quality of our knowledge of the exposure 'fingerprints' for the nickel industry workplaces studied and the combination of expert judgment and sparse data is better than the sparse data alone. For occupational hygiene exposure assessment, our experience suggests that such expert judgment methods can provide a cost-effective means to improve and refine information about workplace hazards. However, more study is warranted for situations where the domain of the quantity of interest has a much wider range of values, e.g. actual exposure values.

Personality judgments in adolescents' families: the perceiver, the target, their relationship, and the family.

The present study investigated whether personality judgments involve different processes in a family setting than in a nonfamily setting. We used the Social Relations Model to distinguish the effects of perceiver, target, perceiver-target relationship, and family on personality judgments. Family members of families with adolescents judged their own and the other members' Big Five factors. Judgments were found to depend on the relevance of personality factors within the family setting: Agreeableness and Conscientiousness were judged most consistently. Large relationship variance indicated that parents adjust their judgments to the target family member; large perceiver variance indicated that adolescents judge family members' personalities rather similarly. However, a comparison of self- and other-judgments showed adolescents' judgments to be no more related to their self-perceptions than parents' judgments. We concluded that the relevance of personality factors may differ on specific tasks within a setting.

Paramedic judgment of the need for trauma team activation for pediatric patients.

OBJECTIVE: To determine the value of paramedic judgment in determining the need for trauma team activation (TA) for pediatric blunt trauma patients. METHODS: A prospective, observational study was conducted at the ED of Children's Hospital Medical Center of Akron between July 12, 1996, and February 28, 1997, in cooperation with Akron Fire Department emergency medical technician-paramedics (EMT-Ps). The ED provides on-line and off-line medical control for pediatric transports. Patients with minor or no identifiable injuries are released at the scene with the instructions to see a physician. The remainder are transported to the ED. The decision for TTA is based on ED trauma protocols as well as emergency physician judgment of injury severity in combination with the judgment of the treating paramedic. During the study, EMT-Ps were asked (before physician input) whether, based solely on their judgment, a patient needed TTA. Patients 0-14 years old who were involved in motor vehicle crashes, bike crashes, or falls from a height of >10 feet were included in the study. TTA was defined as necessary if the patient was admitted to the intensive care unit (ICU) or operating room (OR) for nonorthopedic surgical procedures. Out-of-hospital, ED, and hospital records were reviewed. Coroners' records as well as medical records of all trauma admissions during the study period were reviewed to ensure that the patients released at the scene were not mistriaged. RESULTS: One hundred ninety-two patients met study criteria. Eighty-five patients (44%) were transported to the ED, of whom 12 had TTA. EMT-Ps requested TTA for 10 of these patients, and 2 patients had TTA per ED trauma protocol. Two of the patients who were judged by EMT-Ps to need TTA were admitted to the ICU/OR, and neither of the patients identified by ED trauma protocol to require TTA were admitted to the ICU/OR. Two initially stable patients who did not have TTA deteriorated after arrival to the ED. Both were admitted to the ICU. The sensitivity and specificity of paramedic judgment of the need for TTA for pediatric blunt trauma patients were 50% (95% CI 9.2-90.8) and 87.7% (95% CI 78.0-93.6), respectively. The positive and negative predictive values were 16.7% (95% CI 2.9-49.1) and 97.3% (95% CI 89.6-99.5). None of the patients released at the scene was mistriaged based on the review of the coroners' and trauma admission records. CONCLUSION: Results of this investigation indicate that a small percentage of pediatric blunt trauma patients require TTA. EMT-P judgment alone of the need for TTA for pediatric blunt trauma patients is not sufficiently sensitive to be of clinical use. The low sensitivity is explained by the deterioration in the clinical condition of 2 initially stable patients. The paramedic disposition decisions from the scene were always accurate. Nontransport by emergency medical services (EMS) may be acceptable in some uninjured pediatric trauma patients. Injured pediatric trauma patients who appear to be stable may deteriorate shortly after injury. However, if a pediatric patient appears injured, transport from the scene and examination by a trauma specialist are needed. Finally, the role of paramedic judgment must be further defined by larger studies with urban, rural, and suburban EMS systems before it can be used as a sole predictor of TTA.

Judgment of duration in individuals with ataxia-telangiectasia.

Several clinical investigations with adults suggest that the cerebellum may be critical for judgment of explicit time intervals; however, little work has been done in populations with lesions of the cerebellum acquired during development. We evaluated 17 individuals with ataxia-telangiectasia (AT), an autosomal recessive disorder with on-set in early childhood characterized by diffuse, almost selective, degeneration of the cerebellar cortex, and 21 normal controls, matched for age. Because patients with AT have motor impairment, verbal IQ (VIQ) was used to estimate intelligence; VIQ was significantly lower in the group with AT (p < .0001). Participants were tested using a test of judgment of duration that has been found to be impaired in adults with cerebellar lesions and a contrasting auditory control task (not impaired in adults with cerebellar lesions) involving judgment of pitch. After statistically controlling for VIQ, the 2 groups did not differ significantly on judgment of pitch, but those with AT performed significantly worse than controls on judgment of duration (p = .01). Children and adolescents with AT show deficits in judgment of duration but not of pitch, suggesting that the cerebellum may be critical for judgment of explicit time intervals at all ages.
