Remember judgments and the constraint of direct experience

The most direct assessment of episodic memory is provided by Remember versus Know judgments of recalled or recognised items. We investigate whether Remember judgments reflect episodic memories as a re-experience of formerly experienced events (mental time travel). If they do, they must obey the direct experience constraint: only directly experienced events can be re-experienced but not when the event is known through indirectly conveyed information. In two Experiments participants saw simple events in Power Point, e.g. a car exploding. In the direct experience condition these events were directly perceived. In three further conditions information about the object (particular car), the kind of event (explosion), or both were verbally conveyed. After controlling for a potential encoding specificity effect in Experiment 1, the frequency of Remember judgments was twice as high in the direct experience condition than in the other three conditions. This suggests that Remember judgments are—at least to some degree—subject to the direct experience constraint.     

Genetic Counselors' Judgments of Patient Concerns: Concordance and Consequences

The aims of this prospective study were to determine (a) the concordance between patient concerns and genetic counselors' judgments of these concerns, (b) the predictors of patient and counselor judgments, and (c) the relationship between concordance and patient outcomes. Patients' and counselors' views were sought before and after 131 routine genetic consultations. Before consultations, there was concordance about level of patient concern to within one point in 63% (82/131) of consultations and about type of patient concern in 60–84% of consultations. Lack of concordance in judging level and type of concern was associated with lower satisfaction with information and higher anxiety after the consultation. The biggest predictor of counselor judgment of concern was professional background: doctors judged patients to be more concerned than did nurses. Concordance of concern was predicted by counselors' experience in genetics: less experienced counselors overestimated patient concern. Future research needs to determine whether improving judgment of concern improves patient outcome.     

Use of experienced retrieval ease in self and social judgments

People base judgments from memory on both the content of the information they retrieve and the ease they experience in retrieving it (Schwarz, N., Bless, H., Strack, F., Klumpp, G., Rittenauer-Schatka, H., & Simons, A. (1991). Ease of retrieval as information: another look at the availability heuristic. Journal of Personality and Social Psychology, 61, 195-202). Four studies demonstrate that people rely relatively more on the experienced ease of recall when making judgments about the self compared to judgments about others. This pattern was found for judgments of an “average” (Study 1a) or specific (Study 1b) other. Subjective retrieval ease was less informative when people were relatively less familiar with the specific other person. Providing an alternative explanation for the experienced difficulty of recall affected self, but not social, assessments (Study 2). In addition, the effect generalized to risk judgments about a state of the world; namely, the safety of one’s town (Study 3). A deeper appreciation of when and why people rely on different sources of accessible information when making judgments may help in understanding and reducing social conflict.     

Victim Impact Testimony and Juror Judgments: The Effects of Harm Information and Witness Demeanor1

Victim impact testimony (i.e., testimony concerning the harmful consequences on the victim's surviving family) was examined to determine its effect on the sentencing judgments of mock jurors. Undergraduate students (N= 293) watched a videotaped murder trial simulation, rendered verdicts, and made sentencing judgments. During the penalty phase of the trial, participants were either given no victim impact testimony, or they were given victim impact testimony that varied both the severity of the harm information (mild harm/ severe harm) and the demeanor of the witness (low affect/high affect). The results indicate that information concerning the harm experienced by the victim's relatives, not the affective demeanor of the witness, influenced sentencing judgments. Implications for the U.S. Supreme Court decision in Payne v. Tennessee (1991) are discussed.     

Dyadic judgments based on conflicting samples: The failure to ignore invalid input

The present research demonstrates a so far unrecognized impediment of group performance, metacognitive myopia (Fiedler, 2012). Judges and decision-makers follow the given samples of information uncritically and neglect the metacognitive assessment of the samples' validity. Applying this notion to dyadic judgments, we instructed dyads to jointly estimate conditional probabilities p (Win|A) and p (Win|B) of Lotteries A and B. One person per dyad experienced a valid sample (winning rates conditional on lotteries). The other person experienced an invalid, reverse sample (lotteries conditional on winning). Whereas valid samples provide unbiased estimates of lotteries' winning probabilities, invalid samples can greatly misrepresent the association of winning and lotteries (depending on lottery base rates). Across three experiments, metacognitive myopia—both at the individual and at the dyadic group level—prevented participants from discriminating valid and invalid samples. Group judgments were biased toward erroneous implications of invalid samples, reflecting an equality bias among unequal group members.     

Judgments of Meaning in Life,Religious Beliefs,and the Experience of Cognitive (Dis)Fluency

The primary aim of the current studies was to test whether religiousness interacted with self‐reported levels of meaning in life (MIL) to predict the ease or difficulty in judging one's MIL, the search for meaning itself, and religious doubt. Undergraduate students in Study 1 (N = 111) and adult participants recruited online in Study 2 (N = 206) completed measures of religious beliefs, MIL, cognitive fluency related to MIL, and related variables. Study 3 merged these data sets. In Study 4 (N = 255), online participants completed measures of religious beliefs, cognitive fluency related to religious beliefs, and MIL. Studies 1 and 2 showed that highly religious people with lower MIL reported greater difficulty making their MIL judgments than other people. Study 3 showed that they were also more likely to search for MIL and that disfluency mediated this effect. Study 4 demonstrated that they also reported more difficult judgments of religious beliefs and more religious doubts than their religious peers with high MIL. The current studies demonstrate that the experience of ease or difficulty associated with MIL judgments represents an important yet largely unexamined aspect of MIL. Our findings have implications for understanding the cognitive mechanisms underlying responses to meaning threats.     

The Effect of Self-Imposed Brevity on the Structure of Dyadic Communication

Differences between concise and natural communications in problem solving were investigated by comparing the communications generated by pairs of S s asked to use as few words as possible with the communications by pairs of S s of whom no such request was made. Sixteen male pairs and 16 female pairs, all undergraduate students, were tested. Two modes of communication were used: voice and teletypewriter. An analysis of message function revealed that when S s tried to be brief, they used a larger percentage of messages concerned with the exchange of information and lower percentages of messages that dealt with the rate of communication, judgments, and feedback than under the natural condition. An analysis of parts of speech revealed that those S s who restricted their communications used higher percentages of nouns and adjectives and lower percentages of pronouns, verbs, prepositions, interjections, and articles than did S s who did not restrict their communications. Most of these findings held for both modes of communication.     

Clinical judgment, clinical training, and professional experience

Reviews studies on training, experience, and clinical judgment. The results on the validity of judgments generally fail to support the value of on-the-job experience in mental health fields. The validity results do provide limited support for the value of training. Other results suggest that experienced clinicians are better than less experienced judges at knowing which of their judgments are likely to be correct and which are likely to be wrong. Reasons why clinicians have trouble learning from experience are given. Recommendations are made for improving training and clinical practice.     

Framing experts' (dis)agreements about uncertain environmental events

Agreements and disagreements between expert statements influence lay people's beliefs. But few studies have examined what is perceived as a disagreement. We report six experiments where people rated agreement between pairs of probabilistic statements about environmental events, attributed to two different experts or to the same expert at two different points in time. The statements differed in frame, by focusing on complementary outcomes (45% probability that smog will have negative health effects vs. 55% probability that it will not have such effects), in probability level (45% vs. 55% probability of negative effects), or in both respects. Opposite frames strengthened disagreement when combined with different probability levels. Approximate probabilities can be “framed” in yet another way by indicating reference values they are “over” or “under”. Statements that use different directional verbal terms (over vs. under 50%) indicated greater disagreement than statements with the same directional term but different probability levels (over 50% vs. over 70%). Framing and directional terms similarly affected consistency judgments when both statements were issued by the same expert at different occasions. The effect of framing on perceived agreement was significant for medium (10 and 20 percentage points) differences between probabilities, whereas the effect of directional term was stable for numerical differences up to 40 percentage points. To emphasize agreement between different estimates, they should be framed in the same way. To accentuate disagreements or changes of opinion, opposite framings should be used.     

Perceived direction of rotation of simulated three-dimensional patterns

Direction of rotation judgments were obtained from 72 subjects for computer-generated dot patterns simulating points randomly distributed in a sphere rotating about a vertical axis. The displays were produced either with normal polar projections or with perspective effects limited to the horizontal or to the vertical dimension of the projection. The simulated viewing distance used in the projections and the visual angle subtended by the projected displays were also varied. Accuracy of direction judgments was about the same with perspective effects limited to the vertical dimension as with normal polar projections but did not exceed chance expectations with perspective effects limited to the horizontal dimension. Accuracy was lower at the greater simulated viewing distance and at the greater visual angle.     

The impact of affective information on the professional judgments of more experienced and less experienced auditors

This study examines whether the presence of realistic, yet irrelevant, affective information differentially influences the professional judgments of more experienced and less experienced auditors. In this study, auditors with different experience levels were either provided or not provided with information designed to elicit a negative interpersonal emotional reaction towards a manufacturing client when making an inventory obsolescence risk judgment. The results indicate that the inventory obsolescence risk assessments of less experienced auditors were significantly higher when they were provided with negative affective information on a client than when no such information was provided. No such differences were found for the more experienced auditors. This study suggests that professional experience is one factor that influences individuals' assessments of the informational value of affective reactions. This has implications for developing effective training programs to increase professionals' awareness of the influence that emotional reactions can have on their judgment.

The Need for an Encyclopedia of Psychological Information

The relationship was examined between judgments of relative distance and judgments of relative size made over a surface on which the packing density of the texture elements was progressively increased, from one end of the surface to the other along the S's line of sight. Significant positive correlations were obtained between distance and size judgments made by 32 Ss. This confirmed a weak version of the size-distance invariance hypothesis and supported a prediction contained in Gibson's theory of space perception.     

The effects of age and set size on the fast extraction of egocentric distance

ABSTRACT

Angular direction is a source of information about the distance to floor-level objects that can be extracted from brief glimpses (near one's threshold for detection). Age and set size are two factors known to impact the viewing time needed to directionally localize an object, and these were posited to similarly govern the extraction of distance. The question here was whether viewing durations sufficient to support object detection (controlled for age and set size) would also be sufficient to support well-constrained judgments of distance. Regardless of viewing duration, distance judgments were more accurate (less biased towards underestimation) when multiple potential targets were presented, suggesting that the relative angular declinations between the objects are an additional source of useful information. Distance judgments were more precise with additional viewing time, but the benefit did not depend on set size and accuracy did not improve with longer viewing durations. The overall pattern suggests that distance can be efficiently derived from direction for floor-level objects. Controlling for age-related differences in the viewing time needed to support detection was sufficient to support distal localization but only when brief and longer glimpse trials were interspersed. Information extracted from longer glimpse trials presumably supported performance on subsequent trials when viewing time was more limited. This outcome suggests a particularly important role for prior visual experience in distance judgments for older observers.     

The More the Better? Effects of Training,Experience and Information Amount in Legal Judgments

In an experimental study involving German lay judges, law students and controls, effects of legal training and experience as well as information amount on legal judgments was investigated. In a three (legal knowledge: legal training versus legal experience versus controls) x two (information amount: high versus low) between‐subjects design, 137 participants judged the premeditation of a perpetrator in eight real‐world cases decided by the German Federal Court of Justice. Judgment congruency with the Court's ruling increased with legal training, but official lay judges showed lower congruency compared with student controls. Additionally, legal training and experience corresponded with higher confidence. Emotional reactions to the legal cases were stronger when more information was given for individuals without legal training but decreased for individuals with training. An information‐processing perspective to explain the observed differences in legal judgments is advanced, and the issue of using untrained individuals in the legal decision making process is discussed.

Effects of discriminability and irrelevant information on absolute judgments’

The effects of irrelevant information (0, 1, 2, or 3 bits stimulus) on absolute judgments of size were measured at different levels of discrimination difficulty. The stimuli were 7 small circular spots of light of different sizes, selected from an eaual-discriminability scole, and arranged into 6 pairs that represented different levels of stimulus dissimilarity. Three of the pairs comprised a low-dissimilarity (LD) subgrouping in which different lepels of dissimilarity and discriminability were confounded, whereas the remaining three pairs comprised a high-dissimilarity (HD) subgrouping in which different levels of dissimilarity occurred at a single high level of discriminability. Different colors were used to provide the four levels of irrelevant information; 240 Ss (10 in each of the 24 experimental conditions) made absolute judgments of size under the classical procedure for the method of single stimuli. Separate analyses of errors, reaction times, and rates of information transmission indicated that irrelevant information had an increasingly detrimental effect on absolute judgments as discrimination difficulty was increased (in the LD subgroup), but essentially no effect where discriminations were easily modefin the HD subgroup).     

Effects of changes in size, speed, and distance on the perception of curved 3-D trajectories

Previous research on the perception of 3-D object motion has considered time to collision, time to passage, collision detection, and judgments of speed and direction of motion but has not directly studied the perception of the overall shape of the motion path. We examined the perception of the magnitude of curvature and sign of curvature of the motion path for objects moving at eye level in a horizontal plane parallel to the line of sight. We considered two sources of information for the perception of motion trajectories: changes in angular size and changes in angular speed. Three experiments examined judgments of relative curvature for objects moving at different distances. At the closest distance studied, accuracy was high with size information alone but near chance with speed information alone. At the greatest distance, accuracy with size information alone decreased sharply, but accuracy for displays with both size and speed information remained high. We found similar results in two experiments with judgments of sign of curvature. Accuracy was higher for displays with both size and speed information than with size information alone, even when the speed information was based on parallel projections and was not informative about sign of curvature. For both magnitude of curvature and sign of curvature judgments, information indicating that the trajectory was curved increased accuracy, even when this information was not directly relevant to the required judgment.     

Enhanced counselling for women undergoing BRCA1/2 testing: Impact on knowledge and psychological distress–results from a randomised clinical trial

This randomised controlled trial evaluated the impact of an enhanced counselling (EC) intervention on knowledge about the heritability of breast and ovarian cancer and distress, as a function of BRCA test result, among high-risk women. Before deciding about whether or not to undergo genetic testing, participants were randomly assigned to the EC intervention (N = 69), designed to promote cognitive and affective processing of cancer risk information (following the standard individualised counselling session), or to the control condition (N = 65), which involved standard individualised counselling followed by a general health information session to control for time and attention. Women in the EC group exhibited greater knowledge than women in the control group, 1 week after the intervention. Further, at the affective level, the intervention was found to be the most beneficial for women testing positive: specifically 1 week after test result disclosure, women in the intervention group who tested positive experienced lower levels of distress than women in the control group who tested positive. The findings suggest that the design of counselling aids should include a component that explicitly activates the individual's cognitive–affective processing system.     

Character Disposition and Behavior Type: Influences of Valence on Preschool Children's Social Judgments

The authors studied the influences of valence information on preschool children's (n = 47) moral (good or bad), liking (liked or disliked by a friend), and consequence-of-behavior (reward or punishment) judgments. The authors presented 8 scenarios describing the behavior valence, positive valence (help, share), negative valence (verbal insult, physical aggression), and disposition valence (nice or mean) of characters in social interaction with a friend. Overall, character disposition and behavior valence significantly influenced children's judgments. Moral, liking, and consequence-of-behavior judgments varied significantly by character disposition for both positive behavior scenarios. In contrast, there were fewer significant findings as a function of character disposition for negative behavior scenarios, suggesting that the negative behavior cue somewhat diminished the effect of character disposition on children's judgments. The authors discuss preschool students’ coordination of information about valence of behavior and character disposition and the students’ reluctance to judge that misbehavior warrants punitive consequence.
