Memorability judgments for high- and low-frequency words

Five experiments were conducted in order to examine subjects' judgments of the memorability of high- (HF) and low-frequency (LF) words in the context of a recognition memory task. In Experiment 1, the subjects were provided study/test experience with a list of HF and LF words prior to making memorability judgments for a new list of HF and LF items. The findings were consistent with previous evidence (Greene & Thapar, 1994; Wixted, 1992) suggesting that subjects are not explicitly aware of the greater recognition memorability of LF words. Experiments 2-5 embedded the memorability judgment task within the recognition test itself. In these experiments, the subjects consistently gave higher memorability ratings to LF items. The contrast between the pattern of results found when the subjects made their judgments at the time of list presentation (Experiment 1) and that when they made their judgments during the recognition test (Experiments 2-5) is consistent with recent evidence that even seemingly highly related metamnemonic judgments (e.g., ease of learning judgments vs. judgments of learning for the same items) may be based on very different factors if they occur at different points in the study/test cycle. The present findings are also consistent with the possibility that very rapid retrieval of memorability information for HF and LF words may affect recognition decisions and may contribute to the recognition memory word frequency effect.     

Featural evaluation, integration, and judgment of facial affect

The paradigm of the fuzzy logical model of perception (FLMP) is extended to the domain of perception and recognition of facial affect. Two experiments were performed using a highly realistic computer-generated face varying on 2 features of facial affect. Each experiment used the same expanded factorial design, with 5 levels of brow deflection crossed with 5 levels of mouth deflection, as well as their corresponding half-face conditions, for a total stimulus set of 35 faces. Experiment 1 used a 2-alternative, forced-choice paradigm (either happy or angry), whereas Experiment 2 used 9 rating steps from happy to angry. Results indicate that participants evaluated and integrated information from both features to perceive affective expressions. Both choice probabilities and ratings showed that the influence of 1 feature was greater to the extent that the other feature was ambiguous. The FLMP fit the judgments from both experiments significantly better than an additive model. Our results question previous claims of categorical and holistic perception of affect.     

Visual, orthographic, phonological, and lexical influences in reading.

The fuzzy logical model of perception (FLMP), used as a framework to analyze phenomena in reading, asserts that there are multiple influences on reading performance. Experiments on the dynamic interaction of letter information and orthographic context are presented. Previous results have supported the FLMP over a variety of interactive activation models. These findings indicated that lateral masking and the time course of processing must be accounted for in the theoretical prediction of letter and word recognition. A new finding is that the word superiority effect is not influenced by the nature of the backward masking stimulus, nor is it diminished with letter and word masks, contrary to the predictions of several extant explanations. The FLMP is extended to account for reaction time in reading. Perceptual recognition, naming, and lexical decision tasks reflect the influence of multiple sources of information. These include orthographic structure, spelling-to-speech correspondences, and word frequency. Reading can be productively analyzed as a prototypical pattern recognition situation in which the reader exploits multiple sources of information in perception and action.

The Influence of Self-Ratings versus Peer Ratings on Supervisors' Performance Judgments

This study investigated the extent to which supervisors use feedback from outside sources in making performance judgments. A simulation was conducted in which participants with organizational supervisory experience made an initial performance judgment about a profiled employee. Participants then received additional information that was discrepant from their initial judgment (positive or negative) from one of two sources (the profiled employee himself or one of his peers). The direction of the discrepant information and its source interacted in determining final ratings, such that, participants were more likely to use discrepant information to alter their performance judgments in a consistent direction when the source was a peer than when the source was the employee himself. Furthermore, participants' opinions about the usefulness of peer information for performance judgments moderated this interaction. Specifically, participants who believed that information from an employee's peers was useful, were more likely to use discrepant information provided by a peer when making final performance judgments than were participants who did not believe that information from an employee's peers was useful.

Ambiguity in perception and experimentation.

N. Bruno and J. E. Cutting (see record 1988-28455-001) varied four monocular cues to perceived depth in a factorial design. Subjects judged the distance between test objects. Given main effects in the analysis of variance, the authors concluded that the perceivers integrated the four different sources of information, as opposed to simply selecting a single source. Given no interactions in the analysis of variance, the authors concluded that the integration process was additive rather than multiplicative. The ambiguity inherent in Bruno and Cutting's experiments and analyses is discussed. As presented, their results did not provide evidence for integration of depth cues or evidence for additivity, independence, and parallel processing of the cues. An additional analysis of the distribution of the rating judgments given by their subjects, however, provides some evidence for integration of the cues. The fuzzy logical model of perception (FLMP) is extended to describe perceptual recognition of depth. The model assumes independence of the cues during feature evaluation and a nonadditive integration process in which the least ambiguous cues have the greatest impact on the judgment. The FLMP is contrasted with a model assuming additivity of the cues. Because both models describe the results equally well, it remains for future researchers to provide definitive tests between the models.

The influence of improper sets of information on judgment: How irrelevant information can bias judged probability.

This article introduces 2 new sources of bias in probability judgment, discrimination failure and inhibition failure, which are conceptualized as arising from an interaction between error prone memory processes and a support theory like comparison process. Both sources of bias stem from the influence of irrelevant information on participants' probability judgments, but they postulate different mechanisms for how irrelevant information affects judgment. The authors used an adaptation of the proactive interference (PI) and release from PI paradigm to test the effect of irrelevant information on judgment. The results of 2 experiments support the discrimination failure account of the effect of PI on probability judgment. In addition, the authors show that 2 commonly used measures of judgment accuracy, absolute and relative accuracy, can be dissociated. The results have broad implications for theories of judgment.

Do children profit from looking beyond looks? From similarity-based to cue abstraction processes in multiple-cue judgment.

The authors investigated the ability of 9- to 11-year-olds and of adults to use similarity-based and rule-based processes as a function of task characteristics in a task that can be considered either a categorization task or a multiple-cue judgment task, depending on the nature of the criterion (binary vs. continuous). Both children and adults relied on similarity-based processes in the categorization task. However, adults relied on cue abstraction in the multiple-cue judgment task, whereas the majority of children continued to rely on similarity-based processes. Reliance on cue abstraction resulted in better judgments for adults but not for children in the multiple-cue judgment task. This suggests that 9- to 11-year-olds may have defaulted to similarity-based processes because they were not able to employ a cue abstraction process efficiently.

A quantum theoretical explanation for probability judgment errors.

A quantum probability model is introduced and used to explain human probability judgment errors including the conjunction and disjunction fallacies, averaging effects, unpacking effects, and order effects on inference. On the one hand, quantum theory is similar to other categorization and memory models of cognition in that it relies on vector spaces defined by features and similarities between vectors to determine probability judgments. On the other hand, quantum probability theory is a generalization of Bayesian probability theory because it is based on a set of (von Neumann) axioms that relax some of the classic (Kolmogorov) axioms. The quantum model is compared and contrasted with other competing explanations for these judgment errors, including the anchoring and adjustment model for probability judgments. In the quantum model, a new fundamental concept in cognition is advanced—the compatibility versus incompatibility of questions and the effect this can have on the sequential order of judgments. We conclude that quantum information-processing principles provide a viable and promising new way to understand human judgment and reasoning.

What is the mechanism for fluency in successive recognition?

There are a number of reasons to believe that processing fluency may affect successive recognition judgements, but evidence about the mechanism for these effects is currently lacking. This study used a successive task design to examine whether subjective ease might underlie effects of fluency on recognition. At study subjects performed lexical decisions; in a subsequent test with studied and new items, subjects performed lexical decisions followed immediately by recognition or ease judgments. In a previous study we used that process dissociation procedure to show that recognition in a similar task was largely based upon fluency. In the present study, successive recognition judgments interfered with lexical decision performance to a greater degree than did ease judgments, suggesting that the recognition judgment was not automatic and involved processes additional to the judgment of ease. The data suggest that the fluency involved in successive recognition is more complex than a subjective judgment of ease of processing. One possible mechanism for fluency in recognition may be based upon reductions in the orientation of attention that accompany item repetition.     

Cognitive processing of multidimensional stimuli in schizophrenia: Formal modeling of judgment speed and content.

This article presents a formal, mathematical account of relations between response times on simple cognitive tasks and content of complex judgments involving multiple stimulus dimensions for people with schizophrenia. Changes in multidimensional judgments were viewed as the result of interference from increased stages of encoding with respect to the individual dimensions. Information on dimensional properties encoded earlier in a judgment trial was considered to be more susceptible to loss over the rest of the trial, because of a larger number of encoding stages applied to the remaining dimensional properties. Model predictions were tested with samples of paranoid and nonparanoid schizophrenic participants and controls. Unidimensional encoding speed was assessed by reaction times in an explicit similarity ratings task, and multidimensional judgment content was assessed by the relative importance of different stimulus dimensions to participants' ratings in an implicit similarity ratings task. Results support validity of the model. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Induction and Categorization in Young Children: A Similarity-Based Model.

The authors present a similarity-based model of induction and categorization in young children (SINC). The model suggests that (a) linguistic labels contribute to the perceived similarity of compared entities and (b) categorization and induction are a function of similarity computed over perceptual information and linguistic labels. The model also predicts young children's similarity judgment, induction, and categorization performance under different stimuli and task conditions. Predictions of the model were tested and confirmed in 6 experiments, in which 4- to 5-year-olds performed similarity judgment, induction, and categorization tasks using artificial and real labels (Experiments 1-4) and recognition memory tasks (Experiments 5A and 5B). Results corroborate the similarity-based account of young children's induction and categorization, and they support both qualitative and quantitative predictions of the model.

On the relation between feeling of knowing and lexical decision: Persistent subthreshold activation or topic familiarity?

Exp 1 replicated I. Yaniv and D. E. Meyer's (1987) finding that lexical decision and episodic recognition performance was better for words previously yielding high-accessibility levels (a combination of feeling-of-knowing and tip-of-the-tongue ratings) in comparison with those yielding low-accessibility levels in a rare word definition task. Exp 2 yielded the same pattern even though lexical decisions preceded accessibility estimates by a full week. Exp 3 dismissed the possibility that the Exp 2 results may have been due to a long-term influence from the lexical decision task to the rare word judgment task. These results support a model in which Ss (1) retrieve topic familiarity information in making accessibility estimates in the rare word definition task and (2) use this information to modulate lexical decision performance.

Processing objective and question order effects on the causal relation between memory and judgment in performance appraisal: The tip of the iceberg.

This study extends the research on information processing in performance appraisal judgments. A critical aspect of this research is the relation between memory and judgment processes. Performance appraisal researchers have traditionally assumed that performance judgments are based on memory for specific behaviors; implicit in this assumption is the idea that as memory for specific behaviors improves, judgmental accuracy should also improve. The authors elaborate the circumstances under which performance ratings are more or less likely to be based on previously formed judgments as opposed to memory for specific information. Results indicate that the causal relation between memory and judgment is driven by contextual factors at the time ratings are required as well as at the time information is encoded.

Aging and Conditional Probability Judgments: A Global Matching Approach.

Age differences in bias in conditional probability judgments were investigated based on predictions derived from the Minerva-Decision Making model (M. R. P. Dougherty, C. F. Gettys, & E. E. Ogden, 1999), a global matching model of likelihood judgment. In this study, 248 younger and older adults completed frequency judgment and conditional probability judgment tasks. Age differences in the frequency judgment task are interpreted as an age-related deficit in memory encoding. Older adults' stronger biases in the probability judgment task point to age differences in criterion setting. Age-related biases were eliminated when age groups were equated on memory encoding by means of study time manipulation. The authors conclude that older adults' stronger judgment biases are a function of memory impairment. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The role of typical diagnosticity in stereotype-based judgments.

The relative impact that categorical information and nondiagnostic individuating information each have on stereotype-based judgments was examined. Three experiments tested and found consistent support for the hypothesis that the impact of Ss' stereotypes on their judgments of target individuals would be diluted significantly more by the presence of individuating information that was nondiagnostic for the judgment task at hand but was relatively high in typical diagnosticity (i.e., useful across many social judgment tasks) than by individuating information that was nondiagnostic for the judgment task at hand and was relatively low in typical diagnosticity (i.e., useful across few social judgment tasks). The authors conclude that the typical diagnosticity of individuating information is an important, although previously overlooked, factor in social perception.

Gender Differences in Judgments of Multiple Emotions From Facial Expressions.

The authors tested gender differences in emotion judgments by utilizing a new judgment task (Studies 1 and 2) and presenting stimuli at the edge of conscious awareness (Study 2). Women were more accurate than men even under conditions of minimal stimulus information. Women's ratings were more variable across scales, and they rated correct target emotions higher than did men.

Context, feedback, and the calibration and resolution of confidence in perceptual judgments

The effects of variations in the global task difficulty context on judgmental confidence and confidence calibration were investigated in two experiments requiring perceptual comparisons. In Experiment 1, target judgments of moderate difficulty were embedded in a larger set of more difficult (hard context) or less difficult (easy context) judgments. Decisional response time on the target items was longer in the hard context condition, but there was no effect of difficulty context on target judgment confidence, accuracy, over/underconfidence, calibration, or resolution. In Experiment 2, each subject was exposed to three levels of local judgment difficulty. The global contextual difficulty manipulation involved varying the frequency with which the hard and easy judgments appeared, and the presence or absence of trial-by-trial response feedback was manipulated between subjects. As in Experiment 1, contextual difficulty affected decisional response times but not mean confidence ratings or accuracy. However, we found that providing feedback on a globally difficult task makes calibration worse. Also, resolution (the ability to differentiate correct from incorrect judgments) was found to be superior for easy judgments in a difficult context and for difficult judgments in an easy context. We discuss the implication of these findings for research on confidence and confidence calibration.     

Similarity-based categorization and fuzziness of natural categories

The adequacy of similarity to prototype as an account of categorization in natural concepts was assessed by analyzing the monotonicity of the relation between typicality of an item in a category and the probability of a positive categorization response using data from McCloskey and Glucksberg (1978). The analysis revealed a strong underlying similarity-based threshold curve, with systematic deviations. Further data collection showed that deviations from the curve could be attributed to the effects of unfamiliarity and non-categorical associations on typicality judgments, as well as differences between the perceptual appearance of an item (which tended to boost typicality) and its underlying nature (which tended to boost categorization). The results are discussed in terms of the different presuppositions and task constraints involved in rating typicality as opposed to performing a categorization.     

On the process relationship between person and situation judgments in attribution.

Ss were timed in 3 experiments as they answered 2 consecutive questions about stimulus sentences. The measure of interest was the extent to which answering the 1st question speeded-up answering the 2nd. The order of questions about person and situation influences on behavior was manipulated. Results indicated that the person judgment facilitated the situation judgment significantly more than the situation judgment facilitated the person judgment. The pattern of facilitation was reversed when Ss answered questions about themselves. Results are consistent with a model of concurrent resource allocation to person and situation information in conditions where the primary judgment task involves salient information. However, they are not consistent with a unidimensional or automatic view of person and situation judgments. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
