The Confidence-Accuracy Relationship: The Effects of Confidence Assessment and Choosing1

Male and female college undergraduates were exposed to a staged theft. For half of the subjects, confidence judgments were assessed both before and after viewing a photo lineup. For the other half, confidence judgments were assessed only after viewing the lineup. Subjects in both conditions viewed a target-present or target-absent lineup under negativey biased, unbiased, or positively biased instructions. Across all subjects, confidence and accuracy were significantly correlated (r= .30). There was a significantly stronger relationship between confidence and accuracy among choosers (r= 50) than among nonchoosers (r= .14). Choosing and confidence did not correlate significantly with each other. Identification accuracy was significantly poorer when witnesses had been asked before viewing the lineup to state their confidence that they would make an accurate identification than when confidence was measured only after an identification had been attempted. However, the before-after manipulation did not affect the magnitude of the confidence-accuracy relationship. The present results offer some support for the general proposition that choosing and the timing of confidence assessments should be viewed as moderating variables in the interpretation of the confidence-accuracy relationship. These data offer little support for predictions based upon self-perception theory and are in direct disagreement with the widely held assertion that witnesses are confident in whatever choice they make, regardless of its correctness.     

The elimination‐plus lineup: Testing a modified lineup procedure with confidence

The present study examined whether a modified form of a preidentification confidence rating would provide evidence of a suspect's guilt in addition to the identification decision confidence. Participants (N  = 241) viewed a videotaped mock crime and were presented with a target‐present or target‐absent simultaneous, sequential, elimination, or elimination‐plus lineup procedure; both elimination procedures required 2 separate judgments from the witness (i.e., relative and absolute). The elimination‐plus procedure was identical to that of the elimination procedure with the addition of the confidence rating in between judgment 1 and judgment 2. Confidence after judgment 1, confidence after judgment 2, and the average of the 2 confidence ratings with the elimination‐plus procedure significantly predicted accuracy for choosers. Given that confidence has been recognised by the Supreme Court of the United States, these results shed light on a novel way of utilising confidence in the investigative process.     

Does witnessing gender discrimination predict women's collective action intentions for gender justice? Examining the moderating role of perceived female support

Previous research has indicated that witnessing gender discrimination may instigate women's participation in collective action for gender justice. However, relatively little is known about the role of perceived female support in motivating collective action among women who witness gender discrimination in public life. This study aims to analyse whether and when perceived support from feminist-minded women moderates the association between women's witnessing gender discrimination and their willingness to engage in collective action for gender justice. We argue that the association between witnessing gender discrimination and willingness to engage in collective action depends on the support women perceive from their female friends and family members. In studies of women in the U.S. (Study 1; N = 271) and Ukraine (Study 2; N = 256), witnessing gender discrimination predicted greater willingness to participate in collective action for gender justice, and this association was stronger when female support was perceived to be lower. Study 3 (N = 1,304) replicated the findings of Studies 1 and 2 with self-identified feminist women in Turkey. Our research offers novel insights regarding why perceived lack of female support may encourage women to engage in collective action for gender justice.     

The Psychology of Lineup Identifications1

A review is made of issues and data on eyewitness identifications, and a relative-judgment conceptualization is proposed. It is argued that eyewitnesses are prone to choose the lineup member who most resembles the perpetrator relative to other lineup members as evidenced by studies that manipulated similarity of lineup members. The relative-judgment strategy is fallacious because of the unpredictable occurrence of target-absent lineups and is not corrected fully by instructions to eyewitnesses. An extension of the relative-judgment conceptualization proposes an inverse relationship between the goodness of witnesses' memories (quality and quantity of relevant information available in memory) and witnesses' tendencies to rely on relative judgments. This extended conceptualization was used to derive expectations regarding an experiment (N= 192 eyewitnesses) that used a blank lineup prior to presenting eyewitnesses with the actual lineup. The data indicated that a blank lineup can yield a diagnostic split of eyewitnesses; those who made no identification when presented with a blank lineup were less likely to make false identifications on the actual lineup than either the witnesses who identified someone from the blank lineup or the witnesses who were not presented with a blank lineup. The blank lineup did not produce a significant loss in accurate identifications. The practical implications of using blank lineups and the theoretical utility of the relative-judgment conceptualization are discussed.     

Postdictors of eyewitness errors: can false identifications be diagnosed?

Eyewitness researchers have "postdicted" identification accuracy using witness confidence (S. L. Sporer, S. Penrod, D. Read, & B. Cutler, 1995), response latency (S. L. Sporer, 1993, 1994), and endorsement of statements consistent with using relative versus absolute judgment strategies (D. Dunning & L. B. Stern, 1994; R. C. L. Lindsay & K. Bellinger, 1999). All of these measures were collected from 321 introductory psychology students who had viewed a staged crime and completed a lineup identification task. Some participants received feedback after identification (G. L. Wells & A. L. Bradfield, 1998). Lineup fairness was also used as a postdictor of eyewitness accuracy. Discriminant function analysis indicated that 75.2% of choosers and 63.0% of nonchoosers were correctly classified. Decision time and lineup fairness were the best postdictors of accuracy. The implications for postdicting real eyewitness decisions are discussed.     

“I'm Moderna,what are you?” Evidence that people favor those who received their same brand COVID-19 vaccine

In two studies, we investigated the extent to which people are biased toward people with the same COVID-19 vaccine brand using a monetary allocation task. Informed by theoretical approaches to intergroup bias and the minimal-groups paradigm, we expected that, when deciding how to allocate financial resources among three different people—each with an equal need for assistance but a different COVID-19 vaccine brand—people would allocate more money, on average, to those who received the same versus different vaccine brand than participants personally received. We found in Study 1 (N = 94) that people given a hypothetical $10.00 experimental endowment allocated an average of $2.00 more when a person was a member of their vaccine ingroup than to those from their vaccine brand outgroup. We replicated this effect in Study 2 (N = 219), finding that people continued to allocate more money ($1.42) to a person from their vaccine brand ingroup versus those from their vaccine brand outgroup. Taken together, this work suggests that, among vaccinated people, the brand of another person's vaccine meaningfully influences the allocation of monetary resources and that people are biased toward people with the same COVID-19 vaccine brand. Implications for social identity theories are discussed.     

How elevated blood alcohol concentration level and identification format affect eyewitness memory: A field study

Research shows that alcohol has a small and inconsistent effect on eyewitness recall and no effect on witnesses' lineup decisions. Much of this literature has tested participants with low‐to‐moderate blood alcohol concentration (BAC) levels, and no study has directly examined how identification procedure impacts intoxicated witnesses' decisions. In the present study, bar patrons' (N = 132) BAC levels were recorded before participating in a task. Midway through the task, they were interrupted by an intruder. Participants then recalled the incident via a staged interview and attempted to identify the intruder from a target‐present or target‐absent showup or lineup. Although elevated BAC levels (high as 0.24%) reduced the quantity and quality of information provided, BAC had no effect on witnesses' identification decisions regardless of format. Results highlight the importance of testing witness memory across a broad BAC spectrum and provide evidence that alcohol does not affect witnesses' identification ability.     

Adolescents' evaluations of those who challenge exclusive and inclusive peer norms

Early and middle adolescents' judgements and reasonings about peers who challenge exclusive and inclusive peer group norms were examined across three studies with varying intergroup contexts. Study 1 participants included (N = 199) non-Arab American participants responding to an Arab American/non-Arab American intergroup context. Study 2 included (N = 123) non-Asian and (N = 105) Asian American participants responding to an Asian/non-Asian American intergroup context. Study 3 included (N = 275) Lebanese participants responding to an American/Lebanese intergroup context. Across all three studies participants responded to ingroup and outgroup deviant group members who challenged their peer groups to either include or exclude an outgroup peer with similar interests. Findings indicated that adolescents approved of peers who challenged exclusive peer norms and advocated for inclusion of an ethnic and cultural outgroup, and disapproved of peers who challenged inclusive group norms and advocated for exclusion. Non-Arab and non-Asian American adolescents displayed ingroup bias when evaluating a deviant advocating for exclusion. Additionally, age differences were found among Asian American adolescents. Findings will be discussed in the light of intergroup research on those who challenge injustices.     

The Effect of Backloading Instructions on Eyewitness Identification from Simultaneous and Sequential Lineups

The sequential lineup is multifaceted, including serial presentation of faces, multiple decisions, and often backloading (indicating to an eyewitness that a lineup contains more photos than there actually are). We evaluated the effect of backloading instructions on response bias and sensitivity with an eyewitness identification paradigm. Importantly, we included an ‘undisclosed’ condition that provided no information to participants about the number of lineup members to expect. Experiment 1 (N = 780) tested sequential lineups; Experiment 2 (N = 532) tested simultaneous lineups. As predicted, signal detection analysis showed that backloading induced participants to be more conservative in choosing from both lineup types, but did not affect d′. We conclude that the criminal justice system should be mindful of this shift in response bias, as it has implications for both guilty and innocent suspect identifications.

The effect of humorous instructional materials on interest in a math task

Two studies tested the effect of humor, embedded in learning materials, on task interest. College student participants (N _{Study 1} = 359, N _{Study 2} = 172) learned a new math technique with the presence or absence of humor in the learning program and/or test instructions. Individual interest in math was measured initially and also tested as a factor. The results showed that the effect of humor in the learning program depended on individual interest in math. Humor raised task interest for those with low individual interest in math but slightly lowered task interest for those with high individual interest in math. Mediating variables of this effect were tested across both studies. Although the mediating variables showed inconsistency, humor may affect task interest through affective responses immediately following the instruction, rather than in subsequent interaction with the task.     

Witnesses’ memories for lineup fillers postdicts their identification accuracy

Witnesses who have quick, automatic recognition experiences when viewing a lineup tend to make more accurate decisions than witnesses who engage in slower, more deliberative processes. A novel postdictor of identification accuracy is predicted from these findings: memories for lineup fillers should be stronger among inaccurate, rather than accurate, witnesses. Undergraduate students (N = 320) viewed a mock crime, made a lineup identification decision, and were given a surprise test for their memory for the lineup fillers. Consistent with predictions, better memories for lineup fillers postdicted mistaken identifications and the suspect's innocence. Information gain analyses showed that under some conditions, memory for lineup fillers provided as much information about the suspect's guilt as a lineup identification. Findings are consistent with the idea that postdictors of eyewitness accuracy are valuable to the extent that they measure the automaticity or deliberativeness of the witness's experience when viewing the lineup.     

Effects of postidentification feedback on eyewitness identification and nonidentification confidence

Two experiments investigated new dimensions of the effect of confirming feedback on eyewitness identification confidence using target-absent and target-present lineups and (previously unused) unbiased witness instructions (i.e., "offender not present" option highlighted). In Experiment 1, participants viewed a crime video and were later asked to try to identify the thief from an 8-person target-absent photo array. Feedback inflated witness confidence for both mistaken identifications and correct lineup rejections. With target-present lineups in Experiment 2, feedback inflated confidence for correct and mistaken identifications and lineup rejections. Although feedback had no influence on the confidence-accuracy correlation, it produced clear overconfidence. Confidence inflation varied with the confidence measure reference point (i.e., retrospective vs. current confidence) and identification response latency.     

Expecting tasks to help or hurt subsequent cognitive performance: Variability,accuracy, and bias in forecasted after-effects

After-effects on cognition—where a prior activity either benefits or hinders subsequent cognitive performance—are empirically inconsistent. Do people have insight into when their subjective energy and cognition will be helped or hurt by engaging in prior activities? Studies 1a and 1b (combined N  =  316) find that people expect more demanding and unenjoyable tasks to hinder their subsequent energy and cognitive performance, regardless of their willpower lay theory. Study 2 (N  =  167) examines the accuracy of these forecasts using a within-subject design. Participants’ forecasts of their future subjective states did predict their actual experienced subjective states, but participants were not able to accurately forecast their subsequent maths performance. Additionally, they significantly overestimated the detrimental effects of demanding prior activities on both subjective state and performance. Study 3 (N  =  210) found that participants’ overestimation of detrimental after-effects could result in unnecessary financial costs, suggesting these biased forecasts can have consequences.     

Biased Lineup Instructions: Examining the Effect of Pressure on Children's and Adults' Eyewitness Identification Accuracy1

Two experiments were conducted to examine the effects of pressure on lineup decisions across child and adult eyewitnesses. In both experiments, participants were exposed to a target via videotape and then presented with a 6‐person, target‐absent lineup. Pressure was manipulated via lineup instructions (neutral vs. biased instructions). With neutral lineup instructions, children had a higher false‐positive rate than did adults. With biased lineup instructions, children's patterns of false‐positive responding paralleled that of adults; that is, an increase in false positives occurred. These results suggest that social pressure may not be the only factor driving children's higher false‐positive responding, compared to adults. Potential factors that may be affecting children's lineup decision processes are discussed.     

Children's metacognitive judgments in an eyewitness identification task

Two experiments examined children's metacognitive monitoring of recognition judgments within an eyewitness identification paradigm. A confidence-accuracy (CA) calibration approach was used to examine patterns of calibration, over-/underconfidence, and resolution. In Experiment 1, children (n=619, mean age=11 years 10 months) and adults (n=600) viewed a simulated crime and attempted two separate identifications from 8-person target-present or target-absent lineups given lineup instructions that manipulated witnesses choosing patterns by varying the degree of social pressure. For choosers, but not nonchoosers, meaningful CA relations were observed for adults but not for children. Experiment 2 tested a guided hypothesis disconfirmation manipulation designed to improve the realism of children's metacognitive judgments. Children (N=796, mean age=11 years 11 months) in experimental and control conditions viewed a crime and attempted two separate identifications. The manipulation had minimal impact on the CA relation for choosers and nonchoosers. In contrast to adults, children's identification confidence provides no useful guide for investigators about the likely guilt or innocence of a suspect. These experiments revealed limitations in children's metacognitive monitoring processes that have not been apparent in previous research on recall and recognition with younger children.     

Does customer aggression more strongly affect happy employees? The moderating role of positive affectivity and extraversion

Customer abusive behavior has been found to be a major source of stress for service workers. The main purpose of the present research was to investigate the moderating role of positive affectivity (PA) on the relationship between customer verbal aggression and organizational outcomes. Three studies, based on three separate samples of service employees (Study 1: N = 187; Study 2: N = 422, Study 3: N = 156) demonstrated that frequency of customer aggression was a strong predictor of job-induced tension, job-related attitudes and emotional dissonance even after controlling for negative affectivity. A primary finding of this research was that positive disposition of employees did not reduce the negative consequences of interactions with aggressive customers, but rather increased them. The research provides additional support for the notion that positive disposition can be associated with unfavorable organizational outcomes in certain situation. The results also point out that those who are more likely to be negatively affected by frequent interactions with aggressive customers, are the very service workers that organizations tend to value most. Implications for management and future research are discussed.     

Achieving ego integrity: Personality development in late midlife

Using data from two longitudinal studies of educated white women, we explored precursors and correlates of ego integrity versus despair, which is the last developmental stage in Erikson’s theory of adult development. The women comprising Study 1 graduated from Smith College in 1964 (N = 42); the women comprising Study 2 graduated from Radcliffe College also in 1964 (N = 50). In both studies, hierarchical regressions indicated that women who had resolved their regrets at age 53 achieved higher levels of ego integrity at age 62, and those who had resolved their regrets at age 62 also had higher concurrent levels of ego integrity. Further, in study 2, generativity at age 53 was found to predict ego integrity at age 62.     

Pity for economically disadvantaged groups motivates donation and ally collective action intentions

We argue that pity can motivate collective action intentions toward groups that are both politically and economically deprived. We tested this connection in four online surveys and an experiment. In Study 1 (N = 1,007), pity for the Roma in Hungary predicted collective action intentions, which was replicated in Study 2 in connection with refugees in Germany (N = 191) and in Hungary (N = 563). Study 3 (N = 475) demonstrated that for not economically but politically disadvantaged groups (e.g., sexual minorities), pity was not a predictor of ally action. In an experiment (Study 4, N = 447), pity was just as strong a predictor of collective action intentions as outrage on behalf of an economically and politically disadvantaged outgroup. Pity can be a mobilizing emotion when it comes to groups that are both economically and politically disadvantaged; however, outrage remains more important in the absence of economic hardship.
