Judging response-outcome relations: The role of response-outcome contingency,outcome probability,and method of information presentation

A series of four experiments investigated college students’ judgments of interevent contingency. Subjects were asked to judge the effect of a discrete response Itapping a wire) on the occurrence of a brief outcome (a radio’s buzzing). Pairings of the possible event-state combinations (response-outcome, response-no outcome, no response-outcome, no response-no outcome) were presented in a summary-table (Experiments 2 and 4), in an unbroken-time-line (Experimente 1, 2, and 4), or in a broken-time-line format (Experiment 3). Subjects judged the extent to which the response caused the outcome or prevented it from occurring. Across all methods of information presentation, judgments were a positive function of response-outcome contingency and outcome probability. In the unbroken-time-line condition, judgments of negative response-outcome contingencies were less extreme than judgments of equivalent positive contingencies. This asymmetry was smaller in the broken-time-line condition and in those conditions in which subjects were encouraged to segment an unbroken time line into discrete response outcome units. Finally, judgments of positive and negative relationships were generally symmetrical in the summary-table condition. Relative to the two time-line portrayals, summary table judgments were also less influenced by the overall probability of outcome occurrence. These judgment differences among format conditions suggest that, depending on the method of information presentation, subjects differently partition event sequences into discrete event pairings.     

Strategy use in question-answering: Memory strength and task constraints on fan effects

The time taken to recognize a studied fact increases as a function of the number of other previously studied facts sharing concepts with the test fact. The phenomenon, known as the “fan effect,” has been shown to disappear and sometimes even reverse itself when the set of facts are thematically related. The shift from interference toward facilitation occurs only when subjects can use a plausibility-like strategy. In this experiment, subjects learned variously sized sets of rehted facts about fictitious people. Subjects were asked to make either recognition judgments (“Did you study this fact?”) or consistency judgments (“Is this fact consistent with what you studied7”). Subjects made these judgments both the day the material was acquired and 2 days later. The research reported here supports the hypothesis that, with delay, there is a shift in tendency toward more use of the plausibility strategy, away from the careful strategy of searching for an exact match that produces the fan effect. The plausibility strategy produced either a speedup with greater fan or an increase in error rates when the strategy was inappropriate. Plausibility effects were larger at a delay, in both reaction time and error patterns, regardless of whether subjects were asked to make consistency judgments or recognition judgments. Also as predicted, response times became faster as the tendency to adopt the plausibility strategy without first trying direct retrieval increased.     

Cause and covariate: Development of two related concepts

This study used a rule-analytic technique to investigate the role of event covariation in causal judgment. Junior high school and college subjects were shown information about the co-occurrences of two potentially related events and were asked to make either causal or covariation judgments about the two events. Subjects often failed to identify covariates as causes or identified as causes events which were either unrelated or related in the opposite direction to the event to be explained. Rule analyses indicated that use of mathematically flawed strategies resulted in erroneous covariation and causal judgments. Comparisons between the junior high and college samples showed parallel improvement with increasing age for the two judgments. Strategy analyses of the covariation and causal judgments showed that males defined causes and covariates by similar rules, but that females used different rules to make the two judgments.     

Regression effect in psychophysical judgment

Psychophysical judgment, like all other kinds of judgment, involves a matching or equating of two different domains. When the judgment involves the matching of values on two perceptual continua, the observer tends, on the average, to constrict the range of his adjustments on whichever variable is placed under his control. When the observer adjusts each variable in turn, two different regression lines are produced. This regression effect presumably occurs whenever the results of the matching judgments yield less than a perfect correlation. Illustrative examples are given for the continua, loudness, vibration, brightness, and duration.

You Can’t Drink a Word: Lexical and Individual Emotionality Affect Subjective Familiarity Judgments

For almost 30 years, subjective familiarity has been used in psycholinguistics as an explanatory variable, allegedly able to explain many phenomena that have no other obvious explanation (Gernsbacher in J Exp Psychol General 113:256–281, 1984). In this paper, the hypothesis tested is that the subjective familiarity of words is reflecting personal familiarity with or importance of the referents of words. Using an empirically-grounded model of affective force derived from Wundt (Grundriss der Psychologie [Outlines of Psychology]. Engelmann, Leibzig, 1896) and based in a co-occurrence model of semantics (which involves no human judgment), it is shown that affective force can account for the same variance in a large set of human subjective familiarity judgments as other human subjective familiarity judgments, can predict whether people will rate new words of the same objective frequency as more or less familiar, can predict lexical access as well as human subjective familiarity judgments do, and has a predicted relationship to age of acquisition norms. Individuals who have highly affective reactivity [as measured by Carver and White’s (J Pers Soc Psychol 67(2):319–333, 1994) Behavioral Inhibition Scale and Behavioral Activation Scales] rate words as significantly more familiar than individuals who have low affective reactivity.     

Effects of association and repetition in memory for temporal order

Temporal order recognition memory has been examined previously with tasks involving a recency judgment between a pair of items in a preceding string. Recency judgments are impaired when the earlier item is repeated. The present study employed the comparative recency judgment paradigm, with the lists composed of words. The effect of the inclusion in the list of a high associate of the earlier test item was examined and compared to the effect of repetition. Associative interference was observed, but not in all conditions. Direction of association was a significant factor. The results were interpreted in terms of a model of word recognition proposed by Morton.     

Effects of alternating set for speed or accuracy on response time,accuracy and confidence in a unidimensional discrimination task

Three approaches to a theoretical analysis of confidence judgments are considered: one linking confidence to the number of sensory observations, one based on a distinction between ‘state’ and ‘process’ factors, and a ‘balance of evidence’ hypothesis developed from an accumulator model of discrimination. An experiment is described in which observers were asked to decide which of two parallel lines was the longer, and to rate their confidence in each judgment. Each observer's set for speed or accuracy was manipulated over successive blocks of trials, and effects on response time, accuracy, and confidence were examined. Under an accuracy set, observers produced a higher percentage of correct responses, had longer response times, and made more confident judgments than under a set for speed. Within both speed and accuracy blocks, however, confidence ratings were inversely related to response time. The data on response accuracy, time, and confidence indicate certain deficiencies in either of the first two approaches, but were well accounted for by the third.     

Knowledge Judgments and Object Memory Processes in Early Childhood: Support for the Dual Criterion Account of Object Nameability Judgment

According to the dual criterion account of early linguistic judgment (Merriman & Lipko, 2008 Merriman , W. E. , & Lipko , A. R. (2008). A dual criterion account of the development of linguistic judgment in early childhood. Journal of Memory & Language , 58, 1012–1031. [Google Scholar]), preschool-aged children who possess more efficient object memory processes should also be more accurate judges of whether various objects have known names. In support of this claim, both the accuracy of object recognition and the speed of object naming were found to be correlated with the accuracy of object nameability judgments, but not with the accuracy of four other mentalistic judgments. Nameability judgments tended to be as accurate as judgments of word familiarity and judgments of the relation between seeing and knowing. These three judgments tended to be more accurate than false-belief judgments.     

Cognitive parallels between moral judgment and modal judgment

A central question in the study of moral psychology is how immediate intuition interacts with more thoughtful deliberation in the generation of moral judgments. The present study sheds additional light on this question by comparing adults’ judgments of moral permissibility with their judgments of physical possibility—a form of judgment that also involves the coordination of intuition and deliberation (Shtulman, Cognitive Development 24:293–309, 2009). Participants (N = 146) were asked to judge the permissibility of 16 extraordinary actions (e.g., Is it ever morally permissible for an 80-year-old woman to have sex with a 20-year-old man?) and the possibility of 16 extraordinary events (e.g., Will it ever be physically possible for humans to bring an extinct species back to life?). Their tendency to judge the extraordinary events as possible was predictive of their tendency to judge the extraordinary actions as permissible, even when controlling for disgust sensitivity. Moreover, participants’ justification and response latency patterns were correlated across domains. Taken together, these findings suggest that modal judgment and moral judgment may be linked by a common inference strategy, with some individuals focusing on why actions/events that do not occur cannot occur, and others focusing on how those same actions/events could occur.     

The dimensions of tonal experience: A nonmetric multidimensional scaling approach

Subjects were required in each trial to directly compare two pairs of tones and indicate which pair of tones had the greater subjective difference or dissimilarity. Eleven tones differing in both intensity and frequency were employed. Subjects made binary comparisons among the 55 tone pairs which can be formed from the set of 11 tones. These paired comparisons of tonal intervals were used to determine a two-dimensional Euclidean representation for tonal experience. Loudness and pitch appeared as orthogonal dimensions in this representation. However, a 45-deg rotation of loudness and pitch axes produced axes which could be identified as volume and density. This relationship suggested that volume and density were simple functions of pitch and loudness. Volume and density predictions based on this two-dimensional representation were shown to provide a good account of the data from three experiments on volume and density.     

Confidence in judgments based on incomplete information: An investigation using both hypothetical and real gambles

This study assessed how confidence in judgments is affected by the need to make inferences about missing information. Subjects indicated their likelihood of taking each of a series of gambles based on both probability and payoff information or only one of these sources of information. They also rated their confidence in each likelihood judgment. Subjects in the Explicit Inference condition were asked to explicitly estimate the values of missing information before making their responses while subjects in the Implicit Inference condition were not. The manner in which probability information was framed was also manipulated. Experiment 1 employed hypothetical gambles and Experiment 2 employed gambles with real money. Expressed likelihood of taking gambles was higher when probability was phrased in terms of '% chance of winning' rather than '% chance of losing', but this difference was somewhat less with real gambles than with hypothetical gambles. Confidence ratings in each experiment were actually higher on incomplete information trials than on complete information trials in the Explicit Inference condition. Results were related to the general issue of confidence in judgments.     

Perception of structure in novel music

Two experiments demonstrated the way in which musicians and nonmusicians process realistic music encountered for the first time. A set of tunes whose members were related to each other by a number of specific musical relationships was constructed. In Experiment 1, subjects gave similarity judgments of all pairs of tunes, which were analyzed by the ADDTREE clustering program. Musicians and nonmusicians gave essentially equivalent results: Tunes with different rhythms were rated as being very dissimilar, whereas tunes identical except for being in a major versus a minor mode were rated as being highly similar. In Experiment 2, subjects learned to identify the tunes, and their errors formed a confusion matrix. The matrix was submitted to a clustering analysis. Results from the two experiments corresponded better for the nonmusicians than for the musicians. Musicians presumably exceed nonmusicians in the ability to categorize music in multiple ways, but even nonmusicians extract considerable information from newly heard music.     

Stimulus averaging and the context for judgment

Loudness judgments of stimulus sets composed of four bursts of noise were analyzed for two types of contextual effects: between-set and within-set. Experiment I demonstrated between-set effects for these four-component stimuli; they were shown to be similar to those found in previous work with single stimuli. Experiment 2 tested an averaging model for within-set contextual effects. The results were inconsistent with the model. One interpretation is that there are within-set effects and that these are caused by shifts in the effective range of stimuli. Alternative interpretations attribute the apparent contextual effects either to an averaging of physical values or to an inappropriate scale of judgment.

Human covariation judgment: Accuracy and strategy

Judgment strategy is proposed as a contributor to the variability of findings in past research on human covariation judgment. Mathematically sophisticated judgment strategies will accurately judge all event covariations. However, faulty judgment rules will also produce correct judgments of many event relationships. Several methods have been used in past research to identify subjects' strategies of covariation judgment. Each of these methods indicates that humans employ simplistic, error-prone rules to judge event relationships. Shifts in covariation strategy use are proposed as a source of past findings that judgment accuracy depends on the decision conditions.     

Why do categorization effects occur in comparative judgment tasks?

Three experiments were conducted to understand what eliminates the symbolic distance effect for reaction times (RTs) when subjects learn that items belong to categories. Artificial city locations were judged, and artificial states served as categories. In Experiment 1, whether or not categories were presented and the amount of categorization practice were manipulated. Only those subjects who had practice categorizing cities into states showed a reduced symbolic distance effect for different-state pairs. Analyses of serial position curves indicated that categorization produced faster RTs to different-as compared with their adjacent same-state pairs and it also produced faster RTs for same-state pairs closer to the category border. The border seems to serve as an anchor and facilitates RTs. In Experiments 2a and 2b, distance judgments were made by subjects who either had or had not categorized artificial cities into states. Subjects who learned categories gave larger estimates of distance between cities belonging to different states than to cities belonging to the same state. Categorization seemed to place cities from different states farther apart in psychological space, making their locations more discriminable. This, along with the use of the category border as an anchor, might explain why categorization effects occur in this location judgment task.     

Perception of causal relations in humans: Factors affecting judgments of response-outcome contingencies under free-operant procedures

In three experiments, college studients responded to and rated a range of positive, random, and negative response-outcome contingencies presented in free-operant formats. These experiments sought a paradigm that would yield sensitive and unbiased judgments of response-outcome relations and explored the role of time in the judgment of response-outcome covariation. In Experiment 1, the effects of making continuous and discrete responses on subjects' contingency judgments were compared. In Experiment 2, the effects of changing the temporal definition of discrete responses were examined as were the effects of the amount of exposure to contingency problems. In Experiment 3, the effects of temporal regularity in defining response occurrence and nonoccurrence were investigated. In all three experiments, subjects' judgments were strong linear functions of the programmed contingencies between telegraph key operation and the illumination of a brief light. This result shows free-operant scheduling of response-outcome contingencies to be a highly sensitive and unbiased method of investigating causal perception. Additionally, judgment accuracy was found to be higher for males than for females and to improve as the probability of the subject's making a recorded response rose from .00 toward .50. Finally, a correlational analysis of several possible judgment rules supported the conclusion that subjects rated response-outcome relations on the basis of the difference in the probability of an outcome given their having recently made or not made a response.     

Confidence ratings in speech perception research: Evaluation of an efficient technique for discrimination testing

Discriminability of voice onset time was determined for four naive Ss in order to evaluate the relative efficiency of a testing procedure which utilized confidence ratings along with the conventional oddity task. Ss rated their judgments on oddity trials as “very very sure,” “somewhat sure,” or “just guessing.” Each S’s discrimination scores were given weights according to his ratings, yielding functions that were compared with those computed using unweighted percent correct scores. The confidence-rating technique produced readily interpretable results with about one-third as many judgments as are needed when the conventional procedure is used. Possible problems with the interpretation of the functions and the generalizability of the technique are discussed.     

Developmental picture norms: Relationships between name agreement,familiarity, and visual complexity for child and adult ratings of two sets of line drawings

Developmental differences in name agreement, familiarity, and visual complexity in response to line drawings of common objects were obtained from children and adults. Sixty-one pictures were taken from the Peabody Picture Vocabulary Test-Revised and 259 pictures were taken from the set normed for adults by Snodgrass and Vanderwart (1980). Although there were some differences between the two sets of pictures, the present results replicated the relative independence of these three measures, which was reported by Snodgrass and Vanderwart for adults. Children and adults showed substantial agreement on the names of the pictures. Although the children’s ratings were lower on all measures, the differences were trivial for most pictures. We concluded that judgments of familiarity, complexity, and the names of line drawings of common objects are based primarily on information processing accomplished prior to age 7.
