Comparison processes in social judgment: mechanisms and consequences

This article proposes an informational perspective on comparison consequences in social judgment. It is argued that to understand the variable consequences of comparison, one has to examine what target knowledge is activated during the comparison process. These informational underpinnings are conceptualized in a selective accessibility model that distinguishes 2 fundamental comparison processes. Similarity testing selectively makes accessible knowledge indicating target-standard similarity, whereas dissimilarity testing selectively makes accessible knowledge indicating target-standard dissimilarity. These respective subsets of target knowledge build the basis for subsequent target evaluations, so that similarity testing typically leads to assimilation whereas dissimilarity testing typically leads to contrast. The model is proposed as a unifying conceptual framework that integrates diverse findings on comparison consequences in social judgment.     

'Everything is relative': Comparison processes in social judgment The 2002 Jaspars Lecture

Any judgment involves a comparison of the evaluated target to a pertinent norm or standard, so that comparison processes lie at the core of human judgment. Despite this prominent role, however, little is known about the psychological mechanisms that underlie comparisons and produce their variable consequences. To understand these consequences, one has to examine what target knowledge is sought and activated during the comparison process. Two alternative comparison mechanisms are distinguished. Similarity testing involves a selective search for evidence indicating that the target is similar to the standard and leads to assimilation. Dissimilarity testing involves a selective search for evidence indicating that the target is dissimilar from the standard and leads to contrast. Distinguishing between these alternative mechanisms provides an integrative perspective on comparison consequences in the realm of social comparison and beyond.

Hypothesis Testing as a Moral Choice

Although many researchers may perceive empirical hypothesis testing using inferential statistics to be a value free process, I argue that any conclusion based on inferential statistics contains an important and intractable value judgment. Consequently, I conclude that researchers should use the same rationale for examining the ethical ramifications of committing errors in statistical inference that they use to examine the ethical parameters of a proposed research design.     

Causal diversity effects in information seeking

When trying to determine the root cause of an observed effect, people may seek out information with which to test a candidate hypothesis. In two studies, we investigated how knowledge of causal structure influences this information-seeking process. Specifically, we asked whether people would choose to test for pieces of evidence that were far apart or close together in the learned causal structure of a disease category. In parallel with findings showing people’s tendency to select diverse evidence in argument testing (López, 1995), our participants tested for evidence distantly located within the causal structure. Simultaneously, they rated the probability of occurrence of such diverse evidence as comparatively low. These findings suggest that rather than seeking out information most likely to confirm the hypothesis, people seek out evidence that they believe will most strongly support the hypothesis if present but that they also believe is relatively unlikely to be present (that is, might disconfirm the hypothesis).     

The Beck Anxiety Inventory–Trait (BAIT): A Measure of Dispositional Anxiety Not Contaminated by Dispositional Depression

If aesthetic aspects of art are objective and reside in the art. as Arnheim (1954) argues. then perceiving them may be akin to any other kind of reality testing. Further, if neurosis impairs reality testing, it would also impair aesthetic judgment, especially if aesthetic cues are vital and relevant to the human experience as Arnheim maintains. This hypothesis was investigated by administration of personality tests to measure neuroticism, especially Cattell's Sixteen Personality Factor Questionnaire (16PF), and art judgment tasks, especially Child's slide comparisons, to 105 University of Michigan undergraduates, The hypothesis was supported by a high negative correlation between the 16PF's neuroticism scale and art judgment, r = -.48; t (103) = -5.61 ,p < .0001. The results are discussed in terms of growth versus adjustment models of mental health, and the possible inhibiting role of verbalization over visualization in aesthetic perception.     

Selective interest and psychological practice: A new interpretation of the Burt affair

Anomalies in Burt's twin data have precipitated a prolonged and inconclusive controversy between those who accuse him of fabrication and those who defend his integrity. Here it is suggested that the argument arose in part because differing personal, and especially political, interests predisposed psychologists to diverse interpretations of the evidence. ‘Selective interest’ (James, 1890) leads to a concentration of attention on partial data. The participants in the controversy readily detected this fault in their opponents, but rarely in themselves. It is then suggested that this same factor accounts for the deficiencies in Burt's kinship data. His research was especially vulnerable to ‘selective interest’, and the numerical anomalies in his reports are consistent with this interpretation. It is questioned whether scientific techniques can ever wholly replace personal judgment, with its potential for selective bias.     

认知损伤的评估

该文介绍了作为认知损伤临床评估最优方法的必要条件。评估的一个重要目的是将关于功能区域的优势和劣势的假设公式化,并据此设定适当的康复目标,评价康复的结果。为了达到这一目的,评估应该开始于康复之前,贯穿于康复过程,并持续到康复结束以后。文中比较了两种评估方法：量表法和假设检验法。为了考察认知损伤及其引起的障碍的变化,测验应该具有信度、敏感性和效度。量表法通常不具备这三个必要条件,而假设检验法在这方面更好。该文以一例获得性失语症的词语产出损伤评估为例,介绍了假设检验法的应用     

The influence of distinctive processing on retrieval-induced forgetting

Recall of a portion of a previously experienced list benefits subsequent recall of that portion of the list but leads to poorer recall of nonpracticed items from the same set (Anderson, Bjork, & Bjork, 1994). One explanation for this retrieval-induced forgetting is that during practice of part of a set, the non-practiced items compete for recall and are suppressed; this suppression process inhibits later recall of the nonpracticed items. Two experiments were conducted to investigate the relationship between distinctive processing of the original set and retrieval-induced forgetting, on the assumption that distinctive processing reduces response competition. In the first experiment, distinctive processing induced by difference judgments among the studied items did reduce forgetting relative to a standard encoding task and a similarity judgment task. In fact, the difference judgment task completely eliminated retrieval-induced forgetting. In the second experiment, the similarity judgment task was analyzed in relation to a task assumed to foster associative integration (Anderson & McCulloch, 1999). Even though the similarity judgment met the requirements for associative integration, retrieval-induced forgetting persisted following similarity judgment. The results are consistent with the view that distinctive processing benefits memory within an organizational context (Hunt & McDaniel, 1993; Smith & Hunt, in press).     

Exploring the rabbit hole of possibilities by myself or with my group: The benefits and liabilities of activating counterfactual mind‐sets for information sharing and group coordination

The current experiment explored the effect of activating a counterfactual mind‐set on the discussion of unique information and group judgment accuracy. Evidence suggests that a counterfactual mind‐set is characterized by a focused, analytic mental state and, when activated at the group level, improves group judgment accuracy in the murder mystery paradigm (a hidden profile task). We hypothesized that the beneficial effect of the counterfactual mind‐set would only help group problem‐solving tasks if the mind‐set had been activated at the group level, allowing the analytical mind‐set to play out in an atmosphere of synergistic coordination. In contrast, if this highly focused mental state is activated at the individual level, it could impair group judgment quality because inwardly focused analytical individuals may fail to coordinate their behavior with other group members. Consistent with our hypothesis, activating a counterfactual mind‐set at the individual level had a debilitating effect on the group judgment task, whereas activating a counterfactual mind‐set at the group level had a facilitative effect, increasing information sharing, synergistic coordination and judgment accuracy.

METHODS OF IMPROVING EMPLOYMENT TEST CRITICAL SCORES DERIVED BY JUDGING TEST CONTENT: A REVIEW AND CRITIQUE

Setting critical scores on content valid tests may involve making judgments about test content. A conclusion which has been reached in the testing literature is that the Angoff method is preferred as this type of judgmental method of setting standards or critical scores. The current paper reflects this conclusion, but also discusses several limitations of the Angoff method, and outlines why less than optimal data may be obtained using this preferred method or similar methods. Several techniques are reviewed and critiqued that may be used in conjunction with the Angoff method or similar methods to attempt improvement of the psychometric quality of the critical score data. Components from two psychometric frameworks (generalizability theory and Cronbach's, 1955, accuracy scores) are integrated and applied in assessing the impact that each of the techniques may have on Angoff critical score data. The techniques reviewed can be roughly divided into: (a) procedural methods (involved in the judgment process), and (b) psychometric methods (involved in data analysis following judgment). The present review is intended as a resource to personnel testing specialists who may be interested in methods of bolstering the process of judgmentally deriving critical scores.

Improving the Accuracy of Group Judgment: A Process Intervention Combining Group Facilitation,Social Judgment Analysis,and Information Technology

Interacting groups fail to make judgments as accurate as those of their most capable members due to problems associated with both interaction processes and cognitive processing. Group process techniques and decision analytic tools have been used with groups to combat these problems. While such techniques and tools do improve the quality of group judgment, they have not enabled groups to make judgments more accurate than those of their most capable members on tasks that evoke a great deal of systematic bias. A new intervention procedure that integrates group facilitation, social judgment analysis, and information technology was developed to overcome more fully the problems typically associated with interaction processes and cognitive processing. The intervention was evaluated by testing the hypothesis that groups using this new procedure can establish judgment policies for cognitive conflict tasks that are more accurate than the ones produced by any of their members. An experiment involving 16 four- and five-member groups was conducted to compare the accuracy of group judgments with the accuracy of the judgments of the most capable group member. A total of 96 participants (48 males and 48 females) completed the individual part of the task; 71 of these participants worked in groups. Results indicated that the process intervention enabled small, interacting groups to perform significantly better than their most capable members on two cognitive conflict tasks (p < .05). The findings suggest that Group Decision Support Systems that integrate facilitation, social judgment analysis, and information technology should be used to improve the accuracy of group judgment.     

Interpreting statistical testing: Process and propensity, not population and random sampling

The standard textbook treatment of conventional statistical tests assumes random sampling from a population and interprets the outcome of the statistical testing as being about a population. Problems with this interpretation include that (1) experimenters rarely make any attempt to randomly sample, (2) if random sampling occurred, conventional statistical tests would not precisely describe the population, and (3) experimenters do not use statistical testing to generalize to a population. The assumption of random sampling can be replaced with the assumption that scores were produced by a process. Rejecting the null hypothesis then leads to a conclusion about process, applying to only the subjects in the experiment (e.g., that some difference in the treatment of two groups caused the difference in average scores). This interpretation avoids the problems noted and fits how statistical testing is used in psychology.     

Bias in Counselor Hypothesis Testing: Testing the Robustness of Counselor Confirmatory Bias

Explored the issue of confirmatory bias in counselors' clinical hypothesis testing. Recent research suggests that counselors are subject to a confirmatory bias when using information to test a client hypothesis. The current research tested the robustness of this finding by adding realism and accountability to the experimental situation. Two experiments examined the facts that experienced counselors recalled (a) about a coached client in a naturalistic situation, and (b) when they selected information from a client narrative when told that they would later be held accountable for their selection. In Experiment I, experienced counselors recalled more confirmatory than disconfirmatory information from a coached client's live presentation of factors. In Experiment 2, counselors-in-training selected more confirmatoty than disconfirmatory information from a case history despite the accountability implied by the experimental instructions. The authors concluded (a) that the confirmatory bias is a robust one that may be a natural part of any judgment situation and (b) that counselor education should explicitly train counselors to avoid this confirmatory bias.     

The selective impairment of phonological processing: A case study

A case study is reported of an aphasic patient with fluent speech and markedly superior comprehension of written vs. spoken words. Results of extensive testing supported the hypothesis that the patient suffers from a phonological processing deficit that affects performance in all tasks that require the generation of a phonological code. This selective deficit is interpreted as the underlying cause of diverse symptoms such as asyntactic comprehension of written sentences, the commission of spelling errors in writing, and the production of literal paraphasias and neologisms in spontaneous speech. Alternative possibilities for the classification of this patient are discussed.     

Considering the opposite: a corrective strategy for social judgment

It is proposed that several biases in social judgment result from a failure--first noted by Francis Bacon--to consider possibilities at odds with beliefs and perceptions of the moment. Individuals who are induced to consider the opposite, therefore, should display less bias in social judgment. In two separate but conceptually parallel experiments, this reasoning was applied to two domains--biased assimilation of new evidence on social issues and biased hypothesis testing of personality impressions. Subjects were induced to consider the opposite in two ways: through explicit instructions to do so and through stimulus materials that made opposite possibilities more salient. In both experiments the induction of a consider-the-opposite strategy had greater corrective effect than more demand-laden alternative instructions to be as fair and unbiased as possible. The results are viewed as consistent with previous research on perseverance, hindsight, and logical problem solving, and are thought to suggest an effective method of retraining social judgment.     

A Methodological Note on Overestimates of Reaching Distance: Distinguishing Between Perceptual and Analytical Judgments

Previous research has shown that perceivers tend to overestimate whether an object is within reach. This exploratory study examined the hypothesis that this overestimate is a result of transforming what is typically a perception-action process into an analytical, reflective judgment. It was hypothesized that reaching estimates would be more accurate as analytical processes became less implicated in the judgment. The results indicate that when the judgment of reach was the focal task for perceivers, they overestimated their reach; but when the judgments were made a subsidiary part of aprimary task, with perceivers judging how reachable an object was in order to carry out some other task, their estimates of perceived reach were very accurate. These results support the hypothesis and suggest that perception-action prgcesses should be conceptualized as a complex mode of functioning that can operate independently of analytical processes.     

Practice in visual search produces decreased capacity demands but increased distraction

Lavie (1995) proposed a load account of selective attention, which holds that spare capacity is involuntarily allocated to the processing of irrelevant stimuli. In support of this account, Lavie and Cox (1997) combined a letter search task with a flanker task and found that increasing load (search set size) resulted in decreased interference from an irrelevant distractor letter. In three experiments using a very similar procedure, we varied distractor location and distractor distinctiveness and observed that as load increased (from set size 2 to set size 6), there was a consistent reduction in interference. Critically, we addressed a fundamental hypothesis derived from the load account-that practice reduces capacity demands. This hypothesis leads to the rather counterintuitive prediction that as performance improves with practice, distractor processing should actually increase. Indeed, we found that interference in a high-load condition (set size 6), but not in a low-load condition (set size 2), did increase with practice. We describe a two-stage dilution account of attention that accommodates these results.     

Null hypothesis significance testing: a review of an old and continuing controversy

Null hypothesis significance testing (NHST) is arguably the most widely used approach to hypothesis evaluation among behavioral and social scientists. It is also very controversial. A major concern expressed by critics is that such testing is misunderstood by many of those who use it. Several other objections to its use have also been raised. In this article the author reviews and comments on the claimed misunderstandings as well as on other criticisms of the approach, and he notes arguments that have been advanced in support of NHST. Alternatives and supplements to NHST are considered, as are several related recommendations regarding the interpretation of experimental data. The concluding opinion is that NHST is easily misunderstood and misused but that when applied with good judgment it can be an effective aid to the interpretation of experimental data.
