Positive and negative cue redundancy in multiple cue probability learning

In two separate experiments, 80 introductory psychology students completed a two-cue probability learning task in which cue intercorrelation was positive or negative and cue validities were positive or negative. Results indicated that Ss did not learn the negative validity tasks. In addition, there were no significant differences between groups in achievement due to cue intercorrelation within any one experiment. However, the positive redundancy groups were significantly more consistent in the employment of their decision strategy than the negative redundancy groups when cue validities were positive. The negative redundancy groups were superior to positive redundancy groups in matching; again, when cue validities were positive.     

Empirical tests of the recognition heuristic

The recognition heuristic postulates that individuals should choose a recognized object more often than an unrecognized one whenever recognition is related to the criterion. This behavior has been described as a one‐cue, noncompensatory decision‐making strategy. This claim and other assumptions were tested in four experiments using paired‐comparison tasks with cities and other geographical objects. The main results were (1) that the recognized object was chosen more often than the unrecognized one when the recognition cue was valid; (2) that participants' behavior did not reflect the recognition validity of their own knowledge; (3) that a less‐is‐more effect (i.e., better performance with less knowledge) was either absent or of only small size; and (4) that judgments were influenced by further knowledge, which could even compensate for the recognition cue. In sum, the recognition cue represents an important piece of knowledge in paired comparisons, but apparently not the only one. Copyright © 2006 John Wiley & Sons, Ltd.     

On the psychology of the recognition heuristic: retrieval primacy as a key determinant of its use

The recognition heuristic is a prime example of a boundedly rational mind tool that rests on an evolved capacity, recognition, and exploits environmental structures. When originally proposed, it was conjectured that no other probabilistic cue reverses the recognition-based inference (D. G. Goldstein & G. Gigerenzer, 2002). More recent studies challenged this view and gave rise to the argument that recognition enters inferences just like any other probabilistic cue. By linking research on the heuristic with research on recognition memory, the authors argue that the retrieval of recognition information is not tantamount to the retrieval of other probabilistic cues. Specifically, the retrieval of subjective recognition precedes that of an objective probabilistic cue and occurs at little to no cognitive cost. This retrieval primacy gives rise to 2 predictions, both of which have been empirically supported: Inferences in line with the recognition heuristic (a) are made faster than inferences inconsistent with it and (b) are more prevalent under time pressure. Suspension of the heuristic, in contrast, requires additional time, and direct knowledge of the criterion variable, if available, can trigger such suspension.     

THE EFFECT OF CORRELATED ARTIFACTS AND TRUE VALIDITY ON THE ACCURACY OF PARAMETER ESTIMATION IN VALIDITY GENERALIZATION

The effect of non-zero intercorrelations among the three artifacts (criterion reliability, predictor reliability, and range restriction on the predictor) and true validity on the accuracy of estimation in two validity generalization models (Model 1and Model 2) was investigated. Only the Thylor Series Approximation 1(TSA1) procedure from Model 1 and the procedure with complete sample-based artifact data from Model 2 were included in this study. Six intercorrelation conditions (zero, low positive, medium positive, low negative, low negative and positive, and medium negative and positive) and two distributions of artifacts were used in this investigation. The two major conclusions from this study are: (a) Both models yielded reasonably accurate estimates of the mean of true validities (M_ρ) and (b) only Model 2 produced accurate estimates of the variance of true validities (V_ρ). The need for additional research for accurately estimating V_ρ when the three artifacts and true validity are correlated is recommended.

Task predictability and performance as determinants of confidence in multiple-cue judgments

Two experiments were performed in order to study judges' confidence in their judgments. Experiment I showed that judges' confidence is a direct function of the cue intercorrelation. r_ij in a pure judgmental task. When judges recieved feedback, the effect of r_ij on confidence was, as predicted, reduced. Confidence was, however, systematically related to neither R ²_c nor performance in the feedback condition. Experiment II was a further study of the effect of feedback on confidence. In addition, the hypothesis that the lack of relation between performance and confidence is due to judges' poor knowledge of how they actually perform in probabilistic inference tasks was tested. The experiment showed that differences among judges' confidence is a direct function of task predictability and that judges' confidence is related to how they believe that they perform rather than to how they actually perform. The theoretical as well as the practical importance of studies of confidence in probabilistic inference tasks was discussed.     

Inhibition of object identity in inhibition of return: Implications for encoding and retrieving inhibitory processes

Inhibition of return (IOR) effects, in which participants detect a target in a cued box more slowly than one in an uncued box, suggest that behavior is aided by inhibition of recently attended irrelevant locations. To investigate the controversial question of whether inhibition can be applied to object identity in these tasks, in the present research we presented faces upright or inverted during cue and/or target sequences. IOR was greater when both cue and target faces were upright than when cue and/or target faces were inverted. Because the only difference between the conditions was the ease of facial recognition, this result indicates that inhibition was applied to object identity. Interestingly, inhibition of object identity affected IOR both whenencoding a cue face andretrieving information about a target face. Accordingly, we propose that episodic retrieval of inhibition associated with object identity may mediate behavior in cuing tasks.     

Criterion movements in motor short-term memory experiments

Analysis of both the criterion and reproduction movements from a motor short-term memory experiment using preselected movement is presented. The movement cues under imvestigation, location and distance, were found to interact significantly with amplitude for both the criterion and reproduction movements. It seems that movement cue affects the amplitude of criterion as well as reproduction movements. Thus previous findings by Gundry (1975) are replicated and extended. An increase in a central tendency effect over trials was found which indicated that the criterion movements were effected by proceding movements. The theoretical and methodological implications of these findings are discussed.     

Coherence shifts in probabilistic inference tasks

The fast‐and‐frugal heuristics approach to probabilistic inference assumes that individuals often employ simple heuristics to integrate cue information that commonly function in a non‐reciprocal fashion. Specifically, the subjective validity of a certain cue remains stable during the application of a heuristic and is not changed by the presence or absence of another cue. The parallel constraint satisfaction (PCS) model, in contrast, predicts that information is processed in a reciprocal fashion. Specifically, it assumes that subjective cue validities interactively affect each other and are modified to coherently support the favored choice. Corresponding to the model's simulation, we predicted the direction and the size of such coherence shifts. Cue validities were measured before, after (Experiment 1), and during judgment (Experiments 2 and 3). Coherence shifts were found in environments involving real‐world cue knowledge (weather forecasts) and in a domain for which the application of fast‐and‐frugal heuristics has been demonstrated (city‐size tasks). The results indicate that subjective cue validities are not fixed parameters, but that they are interactively changed to form coherent representations of the task.

The Number of Distinct Basic Values and Their Structure Assessed by PVQ–40

Sixty-eight outpatients from a veterans' administration psychiatry clinic and community mental health center were assessed with 3 measures of depressive personality disorder (DPD)-the Diagnostic Interview for Depressive Personality Disorder (Gunderson, Phillips, Triebwasser, &; Hirschfeld, 1994), the Depressive Personality Disorder Inventory (Huprich, Margrett, Barthelemy, &; Fine, 1996), and the Structured Clinical Interview for DSM-IV Axis II Disorders (First, Gibbon, Spitzer, Williams, &; Benjamin, 1997a)-to evaluate their convergent and discriminant validity. Evidence supporting the measures' validity was mixed. The rate of convergence of depressive personality diagnoses across 3 measures was less than optimal, but the degree of intercorrelation among the measures was strong. Although depressive personality scores had moderate levels of intercorrelations with other personality disorders, the degree of intercorrelation decreased substantially after controlling for depressive symptoms. I conclude that further work is needed to strengthen the validity of measures of DPD.     

Diagnosing criterion-level effects on memory: what aspects of memory are enhanced by repeated retrieval?

Previous research has shown that increasing the criterion level (i.e., the number of times an item must be correctly retrieved during practice) improves subsequent memory, but which specific components of memory does increased criterion level enhance? In two experiments, we examined the extent to which the criterion level affects associative memory, target memory, and cue memory. Participants studied Lithuanian-English word pairs via cued recall with restudy until items were correctly recalled one to five times. In Experiment 1, participants took one of four recall tests and one of three recognition tests after a 2-day delay. In Experiment 2, participants took only recognition tests after a 1-week delay. In both experiments, increasing the criterion level enhanced associative memory, as indicated by enhanced performance on forward and backward cued-recall tests and on tests of associative recognition. An increased criterion level also improved target memory, as indicated by enhanced free recall and recognition of targets, and improved cue memory, as indicated by enhanced free recall and recognition of cues.     

On the reliability of a weighted composite

A general formula for the reliability of a weighted composite has been derived by which that reliability can be estimated from a knowledge of the weights whatever their source, reliabilities, dispersions, and intercorrelations of the components. The Spearman-Brown formula has been shown to be a special case of the general statement. The effect of the internal consistency or intercorrelation of the components has been investigated and the conditions defining the set of weights yielding maximum reliability shown to be that the weight of a component is proportional to the sum of its intercorrelations with the remaining components and inversely proportional to its error variance.     

Timing in the performance of Erik Satie's ‘Vexations’

In traditional studies of single cue probability learning the subject's errors and the covariation he/she establishes between the judgments and the cue (cue dependency) are confounded. Learning results in increased cue dependency which is necessarily accompanied by decreasing errors. This paper presents a method for disentangling errors from cue dependency. This is done by (1) making the criterion contingent upon the judgments instead of the cue, and (2) giving standard instructions, implying that the cue is informative about the criterion. In this way errors are controlled independently of any covariation that the subject may create between the cue and the judgments, and indirectly between the cue and the criterion (task regularity). The paper examines whether subjects aim at small errors or task-regularity when the task does not allow them to do both. It was found that error reduction does occur only when task-regularity can be maintained. Conclusion: task regularity, and thus cue-dependency, has priority to error reduction under the standard conditions used in single cue probability learning experiments. The study may be viewed as an example of conditions under which a cue illusion (false beliefs in the validity of a cue) arises.     

Convergent and discriminant validity of three measures of depressive personality disorder

Sixty-eight outpatients from a veterans' administration psychiatry clinic and community mental health center were assessed with 3 measures of depressive personality disorder (DPD)-the Diagnostic Interview for Depressive Personality Disorder (Gunderson, Phillips, Triebwasser, & Hirschfeld, 1994), the Depressive Personality Disorder Inventory (Huprich, Margrett, Barthelemy, & Fine, 1996), and the Structured Clinical Interview for DSM-IV Axis II Disorders (First, Gibbon, Spitzer, Williams, & Benjamin, 1997a)-to evaluate their convergent and discriminant validity.

The rate of convergence of depressive personality diagnoses across 3 measures was less than optimal, but the degree of intercorrelation among the measures was strong. Although depressive personality scores had moderate levels of intercorrelations with other personality disorders, the degree of intercorrelation decreased substantially after controlling for depressive symptoms. I conclude that further work is needed to strengthen the validity of measures of DPD.     

The effects of advance location cueing on latencies in a single-letter recognition task

Summary This study investigates facilitating effects of foreknowledge of position in single-letter recognition tasks with latency as the dependent variable. Three kinds of cue are used: symbolic cues, location cues and neutral cues. For the effects of symbolic and location cues the following predictions are derived from the literature: increasing benefits with increasing SOAs for symbolic cues and constant benefits with increasing SOAs for location cues.Cue-detection times and letter-recognition times with the different cues were determined in three experiments. In the experiments the same general paradigm was used. In Experiment 1 cue-detection times appeared to differ as a function of cue eccentricity; in Experiments 2 and 3 cues were adjusted in such a way that cue-detection times were about the same. Cues reliably indicated the target position in Experiments 1 and 2; in Experiment 3 cue validity was reduced to 50%.The cueing results conformed partly to the predictions. All experiments suggested a small benefit under symbolic cueing and a larger benefit under location cueing. Except for the smallest SOA used, for both types of cue benefits were invariant over SOAs. The implications of these results in relation to other single-letter recognition studies are briefly discussed.     

The effects of natural category size on memory for episodic encodings

Previous findings indicate that natural category size affects cued recall but not recognition performance. Words that define or belong to larger categories are not as likely to be recalled in the presence of an extralist cue. However, category size has no effect on recognition in the presence of the target as the cue. Theoretically, this difference could be due to inherent differences between these tasks, to the use of different types of test cues, or to differences in the nature of the required responses (naming compared with “yes/no”decisions). Three experiments indicated that none of these factors is a sole determinant. Natural category size effects were found in cued-recall and recognition tasks, with extralist and target cues and regardless of the required response. The critical factor is whether the testing conditions require or encourage subjects to search the category defined by the cue. With the initiation of such a search, information represented in semantic memory is likely to influence memory for episodic information.     

Task requirement and hemifield asymmetry in tachistoscopic partial report performance

It was hypothesized that the amount and direction of differences in tachistoscopic recognition accuracy for the right and the left visual hemifield should depend on the degree to which a partial report task requires exhaustive processing of the test stimulus. Position curves for single-item report were examined using four different tasks. In the Arrow task, Ss had to report a letter which was designated by a bar marker. In the Number task, the position of the critical letter was indicated by the digits 1–8. In the Letter task, the cue stimulus was a letter, and Ss were required to report its position in the test stimulus. In the Alphabetic task, a report on the alphabetically first letter of the test stimulus was required. The tasks were designated to encourage either selective processing (Arrow and Number tasks) or exhaustive processing (Letter and Alphabetic tasks). Right-hemifield superiority was predicted for selective processing, and left-hemifield superiority for exhaustive processing. The predictions were confirmed for the Arrow and Alphabetic tasks. A complete account of the position curves in the Number and Letter tasks required a consideration of the effects of the semantic nature of the cue stimulus and/or the spatial arrangement of cue stimulus and test stimulus. It was concluded that the processing operations underlying partial report are more complex than had been assumed previously.     

Autobiographical elaboration reduces memory distortion: cognitive operations and the distinctiveness heuristic

Retrieval monitoring enhances episodic memory accuracy. For instance, false recognition is reduced when participants base their decisions on more distinctive recollections, a retrieval monitoring process called the distinctiveness heuristic. The experiments reported here tested the hypothesis that autobiographical elaboration during study (i.e., generating autobiographical memories in response to cue words) would lead to more distinctive recollections than other item-specific encoding tasks, enhancing retrieval monitoring accuracy at test. Consistent with this hypothesis, false recognition was less likely when participants had to search their memory for previous autobiographical elaborations, compared to previous semantic judgments. These false recognition effects were dissociated from true recognition effects across four experiments, implicating a recollection-based monitoring process that was independent from familiarity-based processes. Separately obtained subjective measures provided converging evidence for this conclusion. The cognitive operations engaged during autobiographical elaboration can lead to distinctive recollections, making them less prone to memory distortion than other types of deep or semantic encoding.     

More is still not better: Testing the perturbation model of temporal reference memory across different modalities and tasks

The ability of the perturbation model (Jones & Wearden, 2003) to account for reference memory function in a visual temporal generalization task and auditory and visual reproduction tasks was examined. In all tasks the number of presentations of the standard was manipulated (1, 3, or 5), and its effect on performance was compared. In visual temporal generalization the number of presentations of the standard did not affect the number of times the standard was correctly identified, nor did it affect the overall temporal generalization gradient. In auditory reproduction there was no effect of the number of times the standard was presented on mean reproductions. In visual reproduction mean reproductions were shorter when the standard was only presented once; however, this effect was reduced when a visual cue was provided before the first presentation of the standard. Whilst the results of all experiments are best accounted for by the perturbation model there appears to be some attentional benefit to multiple presentations of the standard in visual reproduction.
