The influence of Afrocentric facial features in criminal sentencing

Prior research has shown that within a racial category, people with more Afrocentric facial features are presumed more likely to have traits that are stereotypic of Black Americans compared with people with less Afrocentric features. The present study investigated whether this form of feature-based stereotyping might be observed in criminal-sentencing decisions. Analysis of a random sample of inmate records showed that Black and White inmates, given equivalent criminal histories, received roughly equivalent sentences. However, within each race, inmates with more Afrocentric features received harsher sentences than those with less Afrocentric features. These results are consistent with laboratory findings, and they suggest that although racial stereotyping as a function of racial category has been successfully removed from sentencing decisions, racial stereotyping based on the facial features of the offender is a form of bias that is largely overlooked.     

Feature cues in probability learning: Data base information and judgment

Judgments of probabilistic events are often based partly on some information about past similar events. This study investigates the impact of summarized historical data termed a feature cue on performance in a cue probability learning task. Judges (n = 64) made 150 predictions of a criterion variable (Y_e) from a single cue variable (X). The feature cue variable (Z) provided judges with the “average past criterion” for the cue value on trial i, i.e., the conditional mean . Availability of the feature cue was varied with an AB-BA transfer design. Results demonstrate that the presence of the feature cue greatly imporved prediction achievement and accuracy. Under certain conditions, consistency and cue weighting were also improved by the feature cue aid. Although the feature cue value itself was not used as a prediction, it served as an anchor, around which judgments were dispersed. Implications for decision making with data base information are discussed.     

The role of Afrocentric features in person perception: judging by features and categories

Four studies were conducted to test the hypothesis that group-related physical features may directly activate related stereotypes, leading to more stereotypic inferences over and above those resulting from categorization. As predicted, targets with more Afrocentric features were judged as more likely to have traits stereotypic of African Americans. This effect was found with judgments of African Americans and of European Americans. Furthermore, the effect was not eliminated when a more sensitive measure of categorization processes (category accessibility) was used or when the judgement context made category distinctions salient. Of additional interest was the finding that category accessibility independently affected judgment, such that targets who could be more quickly categorized as group members were judged more stereotypically.     

The impact of attention load on the use of statistical information and coarticulation as speech segmentation cues

In two artificial language learning experiments, we investigated the impact of attention load on segmenting speech through two sublexical cues: transitional probabilities (TPs) and coarticulation. In Experiment 1, we observed that coarticulation processing was resilient to high attention load, whereas TP computation was penalized in a graded manner. In Experiment 2, we showed that encouraging participants to actively search for “word” candidates enhanced overall performance but was not sufficient to preclude the impairment of statistically driven segmentation by attention load. As long as attentional resources were depleted, independently of their intention to find these “words,” participants segmented only TP words with the highest TPs, not TP words with lower TPs. Attention load thus has a graded and differential impact on the relative weighting of the cues in speech segmentation, even when only sublexical cues are available in the signal.     

The automaticity of race and Afrocentric facial features in social judgments

Four experiments were conducted to examine the automaticity of stereotyping based on racial category and (within-race) Afrocentric facial features. Results showed that both forms of stereotyping are efficient processes, able to operate when cognitive resources are highly restricted. The 2 differed, however, in their controllability. Participants demonstrated that they were sensitized to race-based stereotypes and able to control that influence to a significant degree. In contrast, participants appeared to be largely unaware of using Afrocentric features to make stereotypic inferences, and they proved unable to avoid doing so, even when they were given explicit information about the process and they demonstrated that they could easily and reliably identify the relevant features.     

The role of gravitational cues in the judgment of visual orientation

It is argued that, contrary to the views of some theorists, the role of gravitational cues is essentially one of maintaining orientation constancy. In support of this claim, it is shown that the loss of relevant gravitational information when the body is supine results in a significant increase in the disorienting effects of both a tilted visual frame and tilt of the head relative to the trunk.     

The use of recognition information and additional cues in inferences from memory

Goldstein and Gigerenzer's (2002) "Recognition Heuristic" (RH) was tested for its empirical validity in an experimental paradigm with induced recognition of objects. RH claims that upon inferring which of two objects (e.g., cities) scores higher on a criterion (e.g., city size), a recognized object will be chosen over an unrecognized one, if the recognition is a valid predictor of the criterion without considering additional object information. Trying to avoid potential shortcomings of former studies, we (a) used the city population task, (b) provided additional cue information only for recognized cities, and (c) had participants draw inferences from memory. Participants learned city names and additional information about some cities. They also learned that recognition and the additional information were valid predictors of the criterion "city size". In a subsequent decision phase, the additional information about the cities in memory strongly affected the inferences, suggesting that recognition information is clearly integrated into judgments, but by no means in a non-compensatory fashion that would dominate every other cue.     

Accounting for occurrences: a new view of the use of contingency information in causal judgment

When people make causal judgments from contingency information, a principal aim is to account for occurrences of the outcome. When 2 causes are under consideration, the capacity of either to account for occurrences is judged from how likely the cause is to be present when the outcome occurs and from the rate at which the outcome occurs when that cause alone is present, which gives an estimate of the strength of the cause. These propositions are formalized in a weighted averaging model, which successfully predicted several judgmental phenomena not predicted by other models of causal judgment. These include a tendency for judgment of one cause (A) to be reduced as the number of occurrences of when only the other one (B) increases and a tendency for A to receive higher judgments than B if A is better able to account for occurrences than B is even if B has a higher contingency with the outcome than A does. Overshadowing, a tendency for judgments of B to be depressed if A has a higher contingency, is weak or absent when B is better able to account for occurrences than A. Results of several experiments support these and related predictions derived from the accounting for occurrences hypothesis.     

The role of intonation cues in aphasic patients' performance of the grammaticality judgment task

This study investigated the possibility that the reported success of agrammatic aphasic patients in performing auditory grammaticality judgments results from their use of intonational cues to sentence well-formedness. Two agrammatic aphasics, two anomic aphasics, and two nonagrammatic patients with comprehension deficits for semantically reversible sentences were asked to judge grammatical well-formedness in three conditions. Results in a "natural" listening condition replicated the finding of M.C. Linebarger, M.F. Schwartz, and E. M. Saffran (1983, Cognition, 13, 361-392) that agrammatic patients are sensitive to grammaticality despite poor ability to use syntatic cues in comprehension tasks. Two additional listening conditions employed signal-processed auditory stimuli in which the fundamental frequency was normal or was set at a constant level. Right-hemisphere-damaged and normal controls showed no performance deficit for judgments of monotone sentences. The aphasic patients' performance was slightly worse for both signal-processed conditions, but there was little apparent effect of removing sentence intonation on their ability to judge sentence grammaticality. These results indicate that the high levels of performance on grammaticality judgement tasks have not resulted from patients' detection of intonational cues in ungrammatical sentences.     

Developmental differences in the use of retrieval cues to describe episodic information in memory

In four experiments, this study examined some reasons why second and fourth grade children use cues relatively ineffectively to retrieve episodic information in memory. Retrieval success was conceptualized as using a cue to describe episodic information in memory. The experiments manipulated factors hypothesized to affect the discriminability and constructability of compatible encodings of context cue information at retrieval. In general, the effects were accomplished by varying the specificity of cue-target information at acquisition, and similar or different samplings of cue information alone at retrieval by means of orienting questions. Experiment 1 varied the encoding of item specific or categorical information. Experiment 2 varied the encoding of supercategorical or subcategorical information. Experiment 3 used two acquisition trials, crossing Categorical × Item Specific encoding and repeating identical encoding experiences. Experiment 4 varied Separate and Interactive Imagery encoding instructions. The results showed that problems of both discriminability and constructability contribute to developmental differences in the use of retrieval cues.     

The use of hand gestures as self-generated cues for recall of verbally associated targets

This study examined the effects of hand gestures as cues for recall of 40 previously described abstract and concrete words. Participants were either self-cued (SC) with their own self-generated gestures, other-cued (OC) with someone else's gestures, or shown no cues (NC). The SC group had significantly better recall for both word types than either the OC or NC immediately and at a 2-week retrieval interval. Results also showed that when the SC group produced a meaningful gesture, concrete words were cued significantly more often than abstract words, but when total recall (cued and residual) was considered, abstract words were recalled equally well. These results are discussed in the context that hand gestures are a component of subjective organization and are thus distinctive cues for the producer that may facilitate or prime recall.     

Effects of wording and stimulus format on the use of contingency information in causal judgment

There are four kinds of contingency information: occurrences and nonoccurrences of an effect in the presence and in the absence of a cause. Previous studies have shown that these four kinds are not given equal weight in causal judgment. The present research was designed to test two hypotheses about this unequal weighting: that weightings are influenced by the form of the question and other features of the stimulus materials and that unequal weightings occur, in part, because individual differences in the use of contingency information are not evenly distributed across the four kinds of information. Support was found for both hypotheses. However, the effects of question wording were not always as had been predicted, indicating that more needs to be learned about how people interpret the task, instructions, and materials they are given.     

The use of heuristics in intuitive mathematical judgment

Anecdotal evidence points to the use of beauty as an indication of truth in mathematical problem solving. In the two experiments of the present study, we examined the use of heuristics and tested the assumption that participants use symmetry as a cue for correctness in an arithmetic verification task. We manipulated the symmetry of sets of dot pattern addition equations. Speeded decisions about the correctness of these equations led to higher endorsements for both correct and incorrect equations when the addend and sum dot patterns were symmetrical. Therefore, this effect is not due to the fact that symmetry facilitates calculation or estimation. We found systematic evidence for the use of heuristics in solving mathematical tasks, and we discuss how these findings relate to a processing-fluency account of intuition in mathematical judgment.     

Measuring the importance of cues in judgment for individuals: Subjective theories of IQ as a function of heredity and environment

To measure the relative subjective importance attached to heredity and environment, undergraduates, graduate students, and faculty were asked to predict the IQ scores of hypothetical adopted children based on the IQs of the biological mother and father, the IQs of the adoptive parents, and the socioeconomic status of the adoptive parents. Intuitive predictions of IQ were inconsistent with additive, multiple regression models. Rather, the data for individual subjects were consistent with a configural-weight averaging model. Weights derived from this model were correlated with ratings of the relative importance of cues. Judges who rated the environment more important not only had greater weights for the environmental variables, but also placed greater weight on high rather than low scores. The judges who rated heredity more important than environment had greater estimated weights for heredity information and for lower-valued information. Results were thus consistent with the hypothesis that model-derived relative weights and individuals ratings of the relative importance of cues are both measures of the importance that individuals attach to these cues.
