Item Open Access Action Simulations in Acquisition Cost Estimates(2009) Tal, AnerConsumers often lack objective information about product acquisition costs. In such cases, consumers must rely on estimates of acquisition costs in making their choices. The current work examines the influence of mental simulations of product acquisition on estimates of acquisition costs. We suggest that simulations of product acquisition lead estimates to reflect the influence of consumers' current physical states on the experience of a particular cost. Specifically, carrying a heavy burden leads consumers to estimate higher distances to targets when they engage in simulation of walking to targets, but not when they do not engage in such simulation.
Simulation can be either deliberate or spontaneous. Deliberate simulation is engaged when consumers intentionally simulate an action. Spontaneous simulation requires particular conditions for its occurrence, but does not require conscious intent. The specific conditions for the occurrence of spontaneous simulation are the availability of situational inputs and that action be possible in the given situation. We support these ideas in a series of studies.
Study 1 demonstrates preference shifts that occur as a consequence of participants carrying heavy burdens. Participants in this study shifted their preference from an option located a visible but undefined distance away towards one that was available at their current location. Study 2 supports the theory that this shift occurs as a consequence of alterations in estimates of acquisition costs by showing that burdened participants estimate distances as greater than do unburdened participants.
Study 3 provides evidence for the role of mental simulation in producing such changes in estimated acquisition costs by showing that the distance expansion first demonstrated in study 2 occurs when targets are visible, but not when targets are not visible. This result is consistent with the central contention of this dissertation that visibility is critical for spontaneous simulation. Together, the studies support the role of spontaneous simulation in burden leading to distance expansion. Study 4 provides further support for the role of simulation in producing the effects of physical state on estimated acquisition costs by showing deliberate simulation results in similar distance to that of spontaneous simulation.
Studies 5 and 6 further demonstrate the dual roles of spontaneous and deliberate simulation on distance expansion. They show that expansion does not occur when targets are not reachable because they are up in the air (study 5). However, deliberate simulation of realistic (climbing - study 5) or unrealistic (flying - study 6) action restores distance expansion in those circumstances, supporting the role of simulation in leading to consideration of physical state in estimated acquisition costs.
The final study ties together these results by demonstrating the effects of both spontaneous and deliberate simulation in a single setting. Varying both the availability of conditions supporting spontaneous simulation and instructions for deliberate simulation the study allows an examination of the comparative effects of the two types of simulation and of their potential interaction. The study finds that deliberate simulation may produce effects that are larger than those of spontaneous simulation, but spontaneous simulation does not seem to enhance the effects of deliberate simulation.
Item Open Access Age-related differences in resolving semantic and phonological competition during receptive language tasks.(Neuropsychologia, 2016-12) Zhuang, Jie; Johnson, Micah A; Madden, David J; Burke, Deborah M; Diaz, Michele TReceptive language (e.g., reading) is largely preserved in the aging brain, and semantic processes in particular may continue to develop throughout the lifespan. We investigated the neural underpinnings of phonological and semantic retrieval in older and younger adults during receptive language tasks (rhyme and semantic similarity judgments). In particular, we were interested in the role of competition on language retrieval and varied the similarities between a cue, target, and distractor that were hypothesized to affect the mental process of competition. Behaviorally, all participants responded faster and more accurately during the rhyme task compared to the semantic task. Moreover, older adults demonstrated higher response accuracy than younger adults during the semantic task. Although there were no overall age-related differences in the neuroimaging results, an Age×Task interaction was found in left inferior frontal gyrus (IFG), with older adults producing greater activation than younger adults during the semantic condition. These results suggest that at lower levels of task difficulty, older and younger adults engaged similar neural networks that benefited behavioral performance. As task difficulty increased during the semantic task, older adults relied more heavily on largely left hemisphere language regions, as well as regions involved in perception and internal monitoring. Our results are consistent with the stability of language comprehension across the adult lifespan and illustrate how the preservation of semantic representations with aging may influence performance under conditions of increased task difficulty.Item Open Access Age-related slowing in the retrieval of information from long-term memory.(Journal of gerontology, 1985-03) Madden, DJThe present experiment investigated adult age differences in the retrieval of information from long-term memory. Each trial required a decision regarding the synonymy of two visually presented words. On the yes-response trials, the two words were either identical, differed only in case, or were synonyms that differed in case. Age differences in absolute decision time were greater for the synonyms than for the other word pairs, but the proportional slowing of decision time exhibited by the older adults was constant across word-pair type. A generalized age-related slowing in the speed of information processing can currently account for age differences in the retrieval of letter-identity and semantic information from long-term memory.Item Open Access Assessing intraoperative judgment using script concordance testing through the gynecology continuum of practice.(Med Teach, 2014-08) Kow, Nathan; Walters, Mark D; Karram, Mickey M; Sarsotti, Carlos J; Jelovsek, J EricOBJECTIVE: To measure surgical judgment across the Obstetrics and Gynecology (OBGYN) continuum of practice and identify factors that correlate with improved surgical judgment. METHODS: A 45-item written examination was developed using script concordance theory, which compares an examinee's responses to a series of "ill-defined" surgical scenarios to a reference panel of experts. The examination was administered to OBGYN residents, Female Pelvic Medicine and Reconstructive Surgery (FPMRS) fellows, practicing OBGYN physicians and FPMRS experts. Surgical judgment was evaluated by comparing scores against the experts. Factors related to surgical experience were measured for association with scores. RESULTS: In total, 147 participants including 11 residents, 37 fellows, 88 practicing physicians and 11 experts completed the 45-item examination. Mean scores for practicing physicians (65.2 ± 7.4) were similar to residents (67.2 ± 7.1), and worse than fellows (72.6 ± 4.2, p < 0.001) and experts (80 ± 5, p < 0.001). Positive correlations between scores and surgical experience included: annual number of vaginal hysterectomies (r = 0.32, p = <0.001), robotic hysterectomies (r = 0.17, p = 0.048), stress incontinence (r = 0.29, p < 0.001) and prolapse procedures (r = 0.37, p < 0.001). Inverse correlation was seen between test scores and years in practice. (r = -0.19, p = 0.02). CONCLUSION: Intraoperative judgment in practicing OBGYN physicians appears similar to resident physicians. Practicing physicians who perform FPMRS procedures perform poorly on this examination of surgical judgment; lower performance correlates with less surgical experience and the greater amount of time in practice.Item Open Access Clinician judgment vs formal scales for predicting intracerebral hemorrhage outcomes.(Neurology, 2016-01-12) Hwang, David Y; Dell, Cameron A; Sparks, Mary J; Watson, Tiffany D; Langefeld, Carl D; Comeau, Mary E; Rosand, Jonathan; Battey, Thomas WK; Koch, Sebastian; Perez, Mario L; James, Michael L; McFarlin, Jessica; Osborne, Jennifer L; Woo, Daniel; Kittner, Steven J; Sheth, Kevin NOBJECTIVE: To compare the performance of formal prognostic instruments vs subjective clinical judgment with regards to predicting functional outcome in patients with spontaneous intracerebral hemorrhage (ICH). METHODS: This prospective observational study enrolled 121 ICH patients hospitalized at 5 US tertiary care centers. Within 24 hours of each patient's admission to the hospital, one physician and one nurse on each patient's clinical team were each asked to predict the patient's modified Rankin Scale (mRS) score at 3 months and to indicate whether he or she would recommend comfort measures. The admission ICH score and FUNC score, 2 prognostic scales selected for their common use in neurologic practice, were calculated for each patient. Spearman rank correlation coefficients (r) with respect to patients' actual 3-month mRS for the physician and nursing predictions were compared against the same correlation coefficients for the ICH score and FUNC score. RESULTS: The absolute value of the correlation coefficient for physician predictions with respect to actual outcome (0.75) was higher than that of either the ICH score (0.62, p = 0.057) or the FUNC score (0.56, p = 0.01). The nursing predictions of outcome (r = 0.72) also trended towards an accuracy advantage over the ICH score (p = 0.09) and FUNC score (p = 0.03). In an analysis that excluded patients for whom comfort care was recommended, the 65 available attending physician predictions retained greater accuracy (r = 0.73) than either the ICH score (r = 0.50, p = 0.02) or the FUNC score (r = 0.42, p = 0.004). CONCLUSIONS: Early subjective clinical judgment of physicians correlates more closely with 3-month outcome after ICH than prognostic scales.Item Open Access Confidence and gradation in causal judgment.(Cognition, 2022-06) O'Neill, Kevin; Henne, Paul; Bello, Paul; Pearson, John; De Brigard, FelipeWhen comparing the roles of the lightning strike and the dry climate in causing the forest fire, one might think that the lightning strike is more of a cause than the dry climate, or one might think that the lightning strike completely caused the fire while the dry conditions did not cause it at all. Psychologists and philosophers have long debated whether such causal judgments are graded; that is, whether people treat some causes as stronger than others. To address this debate, we first reanalyzed data from four recent studies. We found that causal judgments were actually multimodal: although most causal judgments made on a continuous scale were categorical, there was also some gradation. We then tested two competing explanations for this gradation: the confidence explanation, which states that people make graded causal judgments because they have varying degrees of belief in causal relations, and the strength explanation, which states that people make graded causal judgments because they believe that causation itself is graded. Experiment 1 tested the confidence explanation and showed that gradation in causal judgments was indeed moderated by confidence: people tended to make graded causal judgments when they were unconfident, but they tended to make more categorical causal judgments when they were confident. Experiment 2 tested the causal strength explanation and showed that although confidence still explained variation in causal judgments, it did not explain away the effects of normality, causal structure, or the number of candidate causes. Overall, we found that causal judgments were multimodal and that people make graded judgments both when they think a cause is weak and when they are uncertain about its causal role.Item Open Access Counterfactual Plausibility and Comparative Similarity.(Cognitive science, 2017-05) Stanley, Matthew L; Stewart, Gregory W; Brigard, Felipe DeCounterfactual thinking involves imagining hypothetical alternatives to reality. Philosopher David Lewis (1973, 1979) argued that people estimate the subjective plausibility that a counterfactual event might have occurred by comparing an imagined possible world in which the counterfactual statement is true against the current, actual world in which the counterfactual statement is false. Accordingly, counterfactuals considered to be true in possible worlds comparatively more similar to ours are judged as more plausible than counterfactuals deemed true in possible worlds comparatively less similar. Although Lewis did not originally develop his notion of comparative similarity to be investigated as a psychological construct, this study builds upon his idea to empirically investigate comparative similarity as a possible psychological strategy for evaluating the perceived plausibility of counterfactual events. More specifically, we evaluate judgments of comparative similarity between episodic memories and episodic counterfactual events as a factor influencing people's judgments of plausibility in counterfactual simulations, and we also compare it against other factors thought to influence judgments of counterfactual plausibility, such as ease of simulation and prior simulation. Our results suggest that the greater the perceived similarity between the original memory and the episodic counterfactual event, the greater the perceived plausibility that the counterfactual event might have occurred. While similarity between actual and counterfactual events, ease of imagining, and prior simulation of the counterfactual event were all significantly related to counterfactual plausibility, comparative similarity best captured the variance in ratings of counterfactual plausibility. Implications for existing theories on the determinants of counterfactual plausibility are discussed.Item Open Access Double Prevention, Causal Judgments, and Counterfactuals.(Cognitive science, 2022-05) Henne, Paul; O'Neill, KevinMike accidentally knocked against a bottle. Seeing that the bottle was about to fall, Jack was just about to catch it when Peter accidentally knocked against him, making Jack unable to catch it. Jack did not grab the bottle, and it fell to the ground and spilled. In double-prevention cases like these, philosophers and nonphilosophers alike tend to judge that Mike knocking into the bottle caused the beer to spill and that Peter knocking into Jack did not cause the beer to spill. This difference in causal judgment is a difficult puzzle for counterfactual theories of causal judgment; if each event had not happened, the outcome would not have, yet there is a difference in people's causal judgments. In four experiments and three supplemental experiments, we confirm this difference in causal judgments. We also show that differences in people's counterfactual thinking can explain this difference in their causal judgments and that recent counterfactual models of causal judgment can account for these patterns. We discuss these results in relation to work on counterfactual thinking and causal modeling.Item Open Access Gauging possibilities for action based on friction underfoot.(J Exp Psychol Hum Percept Perform, 2007-10) Joh, Amy S; Adolph, Karen E; Narayanan, Priya J; Dietz, Victoria AStanding and walking generate information about friction underfoot. Five experiments examined whether walkers use such perceptual information for prospective control of locomotion. In particular, do walkers integrate information about friction underfoot with visual cues for sloping ground ahead to make adaptive locomotor decisions? Participants stood on low-, medium-, and high-friction surfaces on a flat platform and made perceptual judgments for possibilities for locomotion over upcoming slopes. Perceptual judgments did not match locomotor abilities: Participants tended to overestimate their abilities on low-friction slopes and underestimate on high-friction slopes (Experiments 1-4). Accuracy improved only for judgments made while participants were in direct contact with the slope (Experiment 5), highlighting the difficulty of incorporating information about friction underfoot into a plan for future actions.Item Open Access Hannah Arendt's Theory of Political Judgment(2014) Schwartz, Jonathan PeterHannah Arendt's theory of political judgment has been an ongoing perplexity among scholars who have written on her. As a result, her theory of judgment is often treated as a suggestive but unfinished aspect of her thought. Drawing on a wider array of sources than is commonly utilized, I argue that her theory of political judgment was in fact the heart of her work. Arendt's project, in other words, centered around reestablishing the possibility of political judgment in a modern world that historically has progressively undermined it. In the dissertation, I systematically develop an account of Arendt's fundamentally political and non-sovereign notion of judgment. We discover that individual judgment is not arbitrary, and that even in the complex circumstances of the modern world there are valid structures of judgment which can be developed and dependably relied upon. The result of this work articulates a theory of practical reason which is highly compelling: it provides orientation for human agency which does not rob it of its free and spontaneous character; shows how we can improve and cultivate our political judgment; and points the way toward the profoundly intersubjective form of political philosophy Arendt ultimately hoped to develop.
Item Open Access How actions create--not just reveal--preferences.(Trends Cogn Sci, 2008-01) Ariely, Dan; Norton, Michael IThe neo-classical economics view that behavior is driven by - and reflective of - hedonic utility is challenged by psychologists' demonstrations of cases in which actions do not merely reveal preferences but rather create them. In this view, preferences are frequently constructed in the moment and are susceptible to fleeting situational factors; problematically, individuals are insensitive to the impact of such factors on their behavior, misattributing utility caused by these irrelevant factors to stable underlying preferences. Consequently, subsequent behavior might reflect not hedonic utility but rather this erroneously imputed utility that lingers in memory. Here we review the roles of these streams of utility in shaping preferences, and discuss how neuroimaging offers unique possibilities for disentangling their independent contributions to behavior.Item Open Access Managerial Decision Making in Censored Environments: Biased Judgment of Demand, Risk, and Employee Capability(2012) Feiler, Daniel CIndividuals have the tendency to believe that they have complete information when making decisions. In many contexts this propensity allows for swift, efficient, and generally effective decision making. However, individuals cannot always see a representative picture of the world in which they operate. This paper examines judgment in censored environments where a constraint, the censorship point, systematically distorts the sample observed by a decision maker. Random instances beyond the censorship point are observed at the censorship point, while instances below the censorship point are observed at their true value. Many important managerial decisions occur in censored environments, such as inventory, risk-taking, and employee evaluation decisions. This empirical work demonstrates a censorship bias - individuals tend to rely too heavily on the observed censored sample, biasing their beliefs about the underlying population. Further, the censorship bias is exacerbated for higher rates of censorship, higher variance in the population, and higher variability in the censorship points. Evidence from four studies demonstrates how the censorship bias can cause managers to underestimate demand for their goods, over-estimate risk in their environments, and underappreciate the capabilities of their employees, which can lead to undesirable outcomes for organizations.
Item Open Access On measuring fuzziness: a comment on "A fuzzy set approach to modifiers and vagueness in natural language".(Journal of experimental psychology. General, 1979-12) Rubin, DCHersh and Caramazza's application of fuzzy set theory to vagueness in natural language is criticized for including in their measures of fuzziness response variability due to experimental and statistical procedures.Item Open Access People over forty feel 20% younger than their age: subjective age across the lifespan.(Psychon Bull Rev, 2006-10) Rubin, David C; Berntsen, DortheSubjective age--the age people think of themselves asbeing--is measured in a representative Danish sample of 1,470 adults between 20 and 97 years of age through personal, in-home interviews. On the average, adults younger than 25 have older subjective ages, and those older than 25 have younger subjective ages, favoring a lifespan-developmental view over an age-denial view of subjective age. When the discrepancy between subjective and chronological age is calculated as a proportion of chronological age, no increase is seen after age 40; older respondents feel 20% younger than their actual age. Demographic variables (gender, income, and education) account for very little variance in subjective age.Item Open Access Telescoping is not time compression: a model of the dating of autobiographical events.(Mem Cognit, 1989-11) Baddeley, Alan D; Rubin, David CA model of telescoping is proposed that assumes no systematic errors in dating. Rather, the overestimation of recent occurrences of events is based on the combination of three factors: (1) Retention is greater for recent events; (2) errors in dating, though unbiased, increase linearly with the time since the dated event; and (3) intrusions often occur from events outside the period being asked about, but such intrusions do not come from events that have not yet occurred. In Experiment 1, we found that recall for colloquia fell markedly over a 2-year interval, the magnitude of errors in psychologists' dating of the colloquia increased at a rate of .4 days per day of delay, and the direction of the dating error was toward the middle of the interval. In Experiment 2, the model used the retention function and dating errors from the first study to predict the distribution of the actual dates of colloquia recalled as being within a 5-month period. In Experiment 3, the findings of the first study were replicated with colloquia given by, instead of for, the subjects.Item Open Access The Child as Econometrician: A Rational Model of Preference Understanding in Children(PLoS ONE, 2014-03) Lucas, Christopher G; Griffiths, Thomas L; Xu, Fei; Fawcett, Christine; Gopnik, Alison; Kushnir, Tamar; Markson, Lori; Hu, JaneRecent work has shown that young children can learn about preferences by observing the choices and emotional reactions of other people, but there is no unified account of how this learning occurs. We show that a rational model, built on ideas from economics and computer science, explains the behavior of children in several experiments, and offers new predictions as well. First, we demonstrate that when children use statistical information to learn about preferences, their inferences match the predictions of a simple econometric model. Next, we show that this same model can explain children's ability to learn that other people have preferences similar to or different from their own and use that knowledge to reason about the desirability of hidden objects. Finally, we use the model to explain a developmental shift in preference understanding.Item Open Access The frequency of voluntary and involuntary autobiographical memories across the life span.(Mem Cognit, 2009-07) Rubin, David C; Berntsen, DortheIn the present study, ratings of the memory of an important event from the previous week on the frequency of voluntary and involuntary retrieval, belief in its accuracy, visual imagery, auditory imagery, setting, emotional intensity, valence, narrative coherence, and centrality to the life story were obtained from 988 adults whose ages ranged from 15 to over 90. Another 992 adults provided the same ratings for a memory from their confirmation day, when they were at about age 14. The frequencies of involuntary and voluntary retrieval were similar. Both frequencies were predicted by emotional intensity and centrality to the life story. The results from the present study-which is the first to measure the frequency of voluntary and involuntary retrieval for the same events-are counter to both cognitive and clinical theories, which consistently claim that involuntary memories are infrequent as compared with voluntary memories. Age and gender differences are noted.Item Open Access The reminiscence bump in the temporal distribution of the best football players of all time: Pelé, Cruijff or Maradona?(Q J Exp Psychol (Hove), 2012) Janssen, Steve MJ; Rubin, David C; Conway, Martin AThe reminiscence bump is the tendency to recall more autobiographical memories from adolescence and early adulthood than from adjacent lifetime periods. In this online study, the robustness of the reminiscence bump was examined by looking at participants' judgements about the quality of football players. Dutch participants (N = 619) were asked who they thought the five best players of all time were. The participants could select the names from a list or enter the names when their favourite players were not on the list. Johan Cruijff, Pelé, and Diego Maradona were the three most often mentioned players. Participants frequently named football players who reached the midpoint of their career when the participants were adolescents (mode = 17). The results indicate that the reminiscence bump can also be identified outside the autobiographical memory domain.Item Open Access The temporal distribution of autobiographical memory: changes in reliving and vividness over the life span do not explain the reminiscence bump.(Mem Cognit, 2011-01) Janssen, Steve MJ; Rubin, David C; St Jacques, Peggy LWhen autobiographical memories are elicited with word cues, personal events from middle childhood to early adulthood are overrepresented compared to events from other periods. It is, however, unclear whether these memories are also associated with greater recollection. In this online study, we examined whether autobiographical memories from adolescence and early adulthood are recollected more than memories from other lifetime periods. Participants rated personal events that were elicited with cue words on reliving or vividness. Consistent with previous studies, most memories came from the period in which the participants were between 6 and 20 years old. The memories from this period were not relived more or recalled more vividly than memories from other lifetime periods, suggesting that they do not involve more recollection. Recent events had higher levels of reliving and vividness than remote events, and older adults reported a stronger recollective experience than younger adults.Item Open Access Treatment intensification in a hypertension telemanagement trial: clinical inertia or good clinical judgment?(Hypertension (Dallas, Tex. : 1979), 2011-10) Crowley, Matthew J; Smith, Valerie A; Olsen, Maren K; Danus, Susanne; Oddone, Eugene Z; Bosworth, Hayden B; Powers, Benjamin JClinical inertia represents a barrier to hypertension management. As part of a hypertension telemanagement trial designed to overcome clinical inertia, we evaluated study physician reactions to elevated home blood pressures. We studied 296 patients from the Hypertension Intervention Nurse Telemedicine Study who received telemonitoring and study physician medication management. When a patient's 2-week mean home blood pressure was elevated, an "intervention alert" prompted study physicians to consider treatment intensification. We examined treatment intensification rates and subsequent blood pressure control. Patients generated 1216 intervention alerts during the 18-month intervention. Of 922 eligible intervention alerts, study physicians intensified treatment in 374 (40.6%). Study physician perception that home blood pressure was acceptable was the most common rationale for nonintensification (53.7%). When "blood pressure acceptable" was the reason for not intensifying treatment, the mean blood pressure was lower than for intervention alerts where treatment intensification occurred (135.3/76.7 versus 143.2/80.6 mm Hg; P<0.0001). Blood pressure acceptable intervention alerts were associated with the lowest incidence of repeat alerts (hazard ratio: 0.69 [95% CI: 0.58 to 0.83]), meaning that the patient home blood pressure was less likely to subsequently rise above goal, despite apparent clinical inertia. This telemedicine intervention targeting clinical inertia did not guarantee treatment intensification in response to elevated home blood pressures. However, when physicians did not intensify treatment, it was because blood pressure was closer to an acceptable threshold, and repeat blood pressure elevations occurred less frequently. Failure to intensify treatment when home blood pressure is elevated may, at times, represent good clinical judgment, not clinical inertia.
