White mock jurors' moral emotional responses to viewing female victim photographs depend on the victim's race.

OBJECTIVE: Jurors often see both premortem photographs of female murder victims before death and postmortem photographs after death. Postmortem photographs are often probative but might prejudicially heighten jurors' other-condemning emotions, such as anger and disgust. Premortem photographs are often not probative and might prejudicially heighten jurors' other-suffering emotions, such as sympathy and empathy. We examined how victim race changes the impact of pre- and postmortem photographs on participants' moral emotions and, in turn, their verdicts. HYPOTHESES: We hypothesized that seeing postmortem (vs. no) photographs would increase convictions through other-condemning emotions for White, but not Latina or Black, victims. We also hypothesized that seeing both pre- and postmortem (vs. only postmortem) photographs would further increase convictions through other-suffering emotions, again for White, but not Latina or Black, female victims. METHOD: White participants (N = 1,261) watched a murder trial video. We manipulated the victim's race (White, Black, or Latina) and whether participants saw no victim photographs, premortem photographs of a female victim, postmortem photographs of a female victim, or both pre- and postmortem photographs. Participants reported the emotions they felt during the trial and chose a verdict. RESULTS: Seeing postmortem (vs. no) victim photographs increased White participants' guilty verdicts through other-condemning emotions when the female victim was White or Latina but not when she was Black. Seeing the combination of pre- and postmortem photographs increased White participants' convictions through other-suffering emotions when the victim was a White woman but not when she was Latina or Black. CONCLUSIONS: Attorneys and judges should consider that jurors' emotional reactions to victim photographs are felt selectively depending on the victim's race and could exacerbate racial biases in jurors' judgments.

Counterintuitive race effects in legal and nonlegal contexts.

OBJECTIVE: Despite documented racial disparities in all facets of the criminal justice system, recent laboratory attempts to investigate racial bias in legal settings have produced null effects or racial-bias reversals. These counterintuitive findings may be an artifact of laboratory participants' attempts to appear unprejudiced in response to social norms that proscribe expressions of racial bias against Black individuals. Furthermore, given pervasive stereotypes linking Black people with crime and heightened attention to issues of racial injustice in the legal system, laboratory participants may be especially likely to attempt to appear unprejudiced in studies examining judgments of Black individuals in legal as opposed to nonlegal contexts. HYPOTHESES: We predicted that counterintuitive race effects (null and pro-Black effects) are more likely to occur in laboratory research examining race in legal than in nonlegal contexts. METHOD: We conducted a quantitative review of race effects in three leading social psychology and legal psychology journals over the last four decades (Personality and Social Psychology Bulletin [PSPB]; Law and Human Behavior [LHB]; Psychology, Public Policy, and Law [PPPL]). We then conducted two experiments in which students (N = 314; Experiment 1) and Mechanical Turk workers (N = 695; Experiment 2) read descriptions of White and Black targets in either legal or nonlegal contexts and rated each target along various characteristics (e.g., dangerous, trustworthy). RESULTS: Our analysis of the literature indicated that counterintuitive race effects were more frequent in studies examining race in legal compared with nonlegal contexts. Our experiments likewise revealed that pro-Black race effects were stronger in legal than in nonlegal contexts. CONCLUSIONS: Laboratory research on racial bias against Black people-especially in legal settings-may produce misleading conclusions about the effects of race on important real-world outcomes. Methodological innovations for studying racial bias are needed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

The role of social desirability and establishing nonracist credentials on mock juror decisions about Black defendants.

OBJECTIVE: Recently, experimental work on racial bias in legal settings has diverged from real-world field data demonstrating racial disparities, instead often producing null or potential overcorrection effects favoring Black individuals over White individuals. We explored the role of social desirability in these counterintuitive effects and tested whether allowing participants to establish nonracist moral credentials increased their willingness to convict a Black defendant. HYPOTHESES: We predicted that establishing nonracist moral credentials would increase convictions of Black defendants-especially for participants likely to harbor racial bias and external motivation to control it. METHOD: In two experiments, we randomly assigned White mock jurors (Study 1: N = 1,018; Study 2: N = 1,253) to establish nonracist moral credentials by acquitting a Black defendant in an initial case, acquit a White defendant in the same case, or see no prior case. Next, they judged an ambiguous case against a Black (Studies 1 and 2) or White (Study 2) defendant. After choosing verdicts, they provided open-ended guesses of what the study was about. Participants completed measures of explicit prejudice, motivations to control prejudice, and political orientation. RESULTS: Most participants who were asked to judge at least one Black defendant guessed that the study was about racial bias and convicted Black defendants less often than did those who guessed the study was about something else. White participants who established nonracist credentials were significantly more likely to convict Black defendants compared with White participants who did not establish nonracist credentials. Subsequent analyses revealed that conservatives showed this predicted credentialing pattern, whereas liberals did not. Credentialed liberals' convictions of Black defendants remained low; instead, they convicted White defendants more than did noncredentialed liberals. CONCLUSIONS: Social desirability plays a clear role in whether White people acquit Black defendants in experiments, which does not align with persistent racial bias in the legal system. Research participants' concern about looking prejudiced might undermine the validity of experiments investigating racial bias in legal settings by artificially inflating pro-Black judgments. The opportunity to credential oneself as nonracist, however, might make conservatives more comfortable making anti-Black legal judgments-whereas credentialed liberals continue to judge Black individuals more favorably than White individuals in legal settings.

Finding the perfect match: Fingerprint expertise facilitates statistical learning and visual comparison decision-making.

Forensic feature-comparison examiners compare-or "match"-evidence samples (e.g., fingerprints) to provide judgments about the source of the evidence. Research demonstrates that examiners in select disciplines possess expertise in this task by outperforming novices-yet the psychological mechanisms underpinning this expertise are unclear. This article investigates one implicated mechanism: statistical learning, the ability to learn how often things occur in the environment. This ability is likely important in forensic decision-making as samples sharing rarer statistical information are more likely to come from the same source than those sharing more common information. We investigated 46 fingerprint examiners' and 52 novices' statistical learning of fingerprint categories and application of this knowledge in a source-likelihood judgment task. Participants completed four measures of their statistical learning (frequency discrimination judgments, bounded and unbounded frequency estimates, and source-likelihood judgments) before and after familiarization to the "ground-truth" category frequencies. Compared to novices, fingerprint examiners had superior domain-specific statistical learning across all measures-both before and after familiarization. This suggests that fingerprint expertise facilitates domain-specific statistical learning-something that has important theoretical and applied implications for the development of training programs and statistical databases in forensic science.

Statistical feature training improves fingerprint-matching accuracy in novices and professional fingerprint examiners.

Forensic science practitioners compare visual evidence samples (e.g. fingerprints) and decide if they originate from the same person or different people (i.e. fingerprint 'matching'). These tasks are perceptually and cognitively complex-even practising professionals can make errors-and what limited research exists suggests that existing professional training is ineffective. This paper presents three experiments that demonstrate the benefit of perceptual training derived from mathematical theories that suggest statistically rare features have diagnostic utility in visual comparison tasks. Across three studies (N = 551), we demonstrate that a brief module training participants to focus on statistically rare fingerprint features improves fingerprint-matching performance in both novices and experienced fingerprint examiners. These results have applied importance for improving the professional performance of practising fingerprint examiners, and even other domains where this technique may also be helpful (e.g. radiology or banknote security).

Morality, punishment, and revealing other people's secrets.

Nine studies represent the first investigation into when and why people reveal other people's secrets. Although people keep their own immoral secrets to avoid being punished, we propose that people will be motivated to reveal others' secrets to punish them for immoral acts. Experimental and correlational methods converge on the finding that people are more likely to reveal secrets that violate their own moral values. Participants were more willing to reveal immoral secrets as a form of punishment, and this was explained by feelings of moral outrage. Using hypothetical scenarios (Studies 1, 3-6), two controversial events in the news (hackers leaking citizens' private information; Study 2a-2b), and participants' behavioral choices to keep or reveal thousands of diverse secrets that they learned in their everyday lives (Studies 7-8), we present the first glimpse into when, how often, and one explanation for why people reveal others' secrets. We found that theories of self-disclosure do not generalize to others' secrets: Across diverse methodologies, including real decisions to reveal others' secrets in everyday life, people reveal others' secrets as punishment in response to moral outrage elicited from others' secrets.

PulsePoint dispatch associated patient characteristics and prehospital outcomes in a mid-sized metropolitan area.

BACKGROUND: Mobile phone-based dispatch of volunteers to out-of-hospital cardiac arrests (OHCA) has been shown to increase the likelihood of early CPR and AED application. In the United States, limited characterization of patients encountered as a result of such systems exists. AIMS: Examine prehospital case characteristics and outcomes from a multi-year deployment of PulsePoint Respond in Pittsburgh, Pennsylvania. METHODS: PulsePoint event timing, location, and associated prehospital electronic health records (ePCRs) were obtained for EMS-encountered OHCA cases that did and did not generate PulsePoint alerts within the service area of Pittsburgh EMS from July 2016 to October 2020. ePCRs were reviewed and OHCA case characteristics were extracted according to the Utstein template. PulsePoint-associated OHCA and non-PulsePoint-associated OHCA were compared. RESULTS: Of 840 total PulsePoint dispatches, 64 (7.6%) were for OHCA associated with a resuscitation attempt. Forty-one (64.1%) were witnessed, 38 (59.4%) received bystander CPR, and 13 (20.0%) of these patients had an AED applied prior to EMS arrival. Twenty-seven (39.7%) had an initial shockable rhythm, and 31 (48.4%) patients achieved ROSC in the field. In the city of Pittsburgh, there were 1229 total OHCA during the study period, with an estimated 29.6% occurring in public. When PulsePoint-associated and publicly occurring non-PulsePoint-associated OHCA were compared, baseline characteristics (age, sex, witnessed status) were similar, but PulsePoint-associated OHCA received more bystander CPR (p = 0.008). CONCLUSIONS: A minority of PulsePoint dispatches in Pittsburgh were triggered by true OHCA. The majority of OHCA during the study period occurred within private residences where PulsePoint responders are not currently dispatched. PulsePoint dispatches were associated with prognostically favorable OHCA characteristics and increased bystander CPR performance.

Can neuroimaging prove pain and suffering?: The influence of pain assessment techniques on legal judgments of physical versus emotional pain.

OBJECTIVES: It is difficult to "prove" pain and suffering-particularly emotional suffering. Neuroimaging technology might bolster pain claims in civil cases by making pain seem less subjective. We examined how neuroimaging of physical and emotional pain influences judgments of pain and suffering across nonlegal and legal contexts. HYPOTHESES: We hypothesized that participants would rate pain assessed using neuroimaging as more severe and award higher compensation than pain assessed using self-report measures. We also hypothesized that participants would rate physical (vs. emotional) pain as more severe, except when the pain claim was bolstered by a neuroimaging assessment. METHOD: In two experiments, we tested how pain assessment techniques influence perceptions of pain severity and monetary compensation differently for physical or emotional pain. Using a within-subjects design, participants (Experiment 1, N = 411, 59% male, 80% White) read 6 vignettes that described a person's chronic physical or emotional pain, evaluated using a clinical assessment, neuropsychological assessment, or neuroimaging assessment. We conceptually replicated Experiment 1 in a legal context (Experiment 2, N = 353, 42% male; 80% White) and tested whether the neuroimaging effect was due to knowing that the pain was assessed by neuroimaging or also required the inclusion of a neuroimage. RESULTS: When pain was assessed using neuroimaging (vs. non-neuroimaging assessments), participants rated the pain as more severe and gave larger monetary awards. When a person alleged physical (vs. emotional) pain, participants rated the pain as more severe and gave larger monetary awards. We conceptually replicated these findings in Experiment 2 and found that the neuroimaging effect was due to hearing about neuroimaging assessment and did not necessitate the inclusion of a neuroimage. CONCLUSION: Neuroimaging technology could be extremely useful for plaintiffs trying to overcome the difficult hurdle of proving their pain.

Projected resurgence of COVID-19 in the United States in July-December 2021 resulting from the increased transmissibility of the Delta variant and faltering vaccination.

WHAT IS ALREADY KNOWN ABOUT THIS TOPIC?: The highly transmissible SARS-CoV-2 Delta variant has begun to cause increases in cases, hospitalizations, and deaths in parts of the United States. With slowed vaccination uptake, this novel variant is expected to increase the risk of pandemic resurgence in the US in July-December 2021. WHAT IS ADDED BY THIS REPORT?: Data from nine mechanistic models project substantial resurgences of COVID-19 across the US resulting from the more transmissible Delta variant. These resurgences, which have now been observed in most states, were projected to occur across most of the US, coinciding with school and business reopening. Reaching higher vaccine coverage in July-December 2021 reduces the size and duration of the projected resurgence substantially. The expected impact of the outbreak is largely concentrated in a subset of states with lower vaccination coverage. WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE?: Renewed efforts to increase vaccination uptake are critical to limiting transmission and disease, particularly in states with lower current vaccination coverage. Reaching higher vaccination goals in the coming months can potentially avert 1.5 million cases and 21,000 deaths and improve the ability to safely resume social contacts, and educational and business activities. Continued or renewed non-pharmaceutical interventions, including masking, can also help limit transmission, particularly as schools and businesses reopen.

Modeling of Future COVID-19 Cases, Hospitalizations, and Deaths, by Vaccination Rates and Nonpharmaceutical Intervention Scenarios - United States, April-September 2021.

After a period of rapidly declining U.S. COVID-19 incidence during January-March 2021, increases occurred in several jurisdictions (1,2) despite the rapid rollout of a large-scale vaccination program. This increase coincided with the spread of more transmissible variants of SARS-CoV-2, the virus that causes COVID-19, including B.1.1.7 (1,3) and relaxation of COVID-19 prevention strategies such as those for businesses, large-scale gatherings, and educational activities. To provide long-term projections of potential trends in COVID-19 cases, hospitalizations, and deaths, COVID-19 Scenario Modeling Hub teams used a multiple-model approach comprising six models to assess the potential course of COVID-19 in the United States across four scenarios with different vaccination coverage rates and effectiveness estimates and strength and implementation of nonpharmaceutical interventions (NPIs) (public health policies, such as physical distancing and masking) over a 6-month period (April-September 2021) using data available through March 27, 2021 (4). Among the four scenarios, an accelerated decline in NPI adherence (which encapsulates NPI mandates and population behavior) was shown to undermine vaccination-related gains over the subsequent 2-3 months and, in combination with increased transmissibility of new variants, could lead to surges in cases, hospitalizations, and deaths. A sharp decline in cases was projected by July 2021, with a faster decline in the high-vaccination scenarios. High vaccination rates and compliance with public health prevention measures are essential to control the COVID-19 pandemic and to prevent surges in hospitalizations and deaths in the coming months.

Subjective interpretation of "objective" video evidence: Perceptions of male versus female police officers' use-of-force.

OBJECTIVE: The police face great scrutiny after highly publicized instances of lethal force. Dash-camera footage ostensibly provides "objective" evidence of whether the force was excessive. We tested whether participants interpreted the same "objective" video of an officer exerting force differently based on the officer's gender and race. HYPOTHESIS: We predicted that when (a) a male (vs. female) officer used force and (b) a Black (vs. White) officer used force, participants would endorse more internal and less external explanations for their use-of-force, which would be associated with less trust in and perceived effectiveness of the officer. METHOD: We randomly assigned Amazon's Mechanical Turk workers (N = 452; 53% female, 80% White) to (a) see a segment of a police-civilian interaction video that either included or did not include exertion of force, and to believe that the officer was (b) male versus female, and (c) Black versus White. They reported their trust in the officer and perceptions of the officer's effectiveness, and their degree of agreement with external and internal attributions for the officer's behavior. RESULTS: When officers used force, people trusted officers less (d = 1.13) and perceived them to be less effective (d = .78) relative to when they did not. Despite all participants viewing the same interaction, people who thought they saw a male (vs. female) officer perceived his use-of-force to be driven more by internal traits, such as being aggressive and emotionally reactive, and less by the external situation, which was associated with decreased trust and perceived effectiveness. In contrast, people perceived female (vs. male) officers' force to be driven more by external aspects of the dangerous situation, which was associated with increased trust and perceived effectiveness. This pattern did not depend on the officers' race or participants' gender. CONCLUSION: This constitutes a rare instance of women benefiting from violating gender stereotypes in the workplace because people assumed her counterstereotypical behavior was more justified by the situation and less about her being an aggressive and emotionally reactive person.

Can you get there from here? An analysis of walkability among PulsePoint CPR alert dispatches.

BACKGROUND: Bystander CPR before the arrival of EMS is a major factor in out of hospital cardiac arrest (OHCA) survival. To recruit trained bystanders, mobile phone-based alert systems have been developed, but their limitations are not well understood. OBJECTIVE: We investigated the effects of landscape features on the capabilities of the PulsePoint CPR dispatch platform in Allegheny County, Pennsylvania. We hypothesized that landscape features would reduce walkable area within dispatch zones and that larger alert radii could mitigate these effects. METHODS: CPR alert location data were obtained from the Allegheny County 911 PulsePoint deployment from July 2016-2019 (n = 1100). PulsePoint, a smartphone-based citizen CPR dispatch platform, alerts volunteers to public OHCAs within 400 m. Digital maps of alerts were generated for walkability analysis using the image Labeler MATLAB polygon tool. Unwalkable areas were labeled, classified into five categories, and quantified. RESULTS: Of the 1100 events analyzed, encompassing 212 mi2, 357 (32.45%) had no impediments to walkability. Within a 400 m radius of partially impeded events, the median proportion of obstructed area was 0.2250 (Min: 0.0005, Max: 0.8338, IQR: 0.3004, Sx: 0.1923). When the alert radius was expanded to 468 m, the median increased to 0.2336 (Min: 0.0016, Max: 0.8597, IQR: 0.3064, Sx: 0.1950). The percentages of total unwalkable area by each category were: terrain (54.286%), water (24.674%), road w/o crosswalk (11.3197%), railroad (7.4100%), private property (2.3102%). CONCLUSIONS: In this region, most PulsePoint alerts had unwalkable areas, mostly from terrain and water. Contrary to our initial hypotheses, moderately increasing dispatch radius did not improve walkability.

Simulating Public Buses as a Mobile Platform for Deployment of Publicly Accessible Automated External Defibrillators.

Introduction: Public access defibrillation (PAD) programs seek to optimize locations of automated external defibrillators (AEDs) to minimize the time from out-of-hospital cardiac arrest (OHCA) recognition to defibrillation. Most PAD programs have focused on static AED (S-AED) locations in high traffic areas; pervasive electronic data infrastructure incorporating real-time geospatial data opens the possibility for AED deployment on mobile infrastructure for retrieval by nearby non-passengers. Performance characteristics of such systems are not known. Hypothesis: We hypothesized that publicly accessible AEDs located on buses would increase publicly accessible AED coverage and reduce AED retrieval time relative to statically located AEDs. Methods: S-AED sites in Pittsburgh, PA were identified and consolidated to 1 AED per building for analysis (n = 582). Public bus routes and schedules were obtained from the Port Authority of Allegheny County. OHCA locations and times were obtained from the Pittsburgh site of the Resuscitation Outcomes Consortium. Two simulations were conducted to assess the characteristics and impact of AEDs located on buses. In Simulation #1, geographic coverage area of AEDs located on buses (B-AEDs) was estimated using a 1/8th mile (201 m) retrieval radius during weekday, Saturday and Sunday periods. Cumulative geographic coverage across each period of the week was compared to S-AED coverage and the added coverage provided by B-AEDs was calculated. In Simulation #2, spatiotemporal event coverage was estimated for historical OHCA events, assuming constraints designed to reflect real world AED retrieval scenarios. Event coverage and AED retrieval time were compared between B-AEDs and S-AEDs across periods of the week and residential/nonresidential spatial areas. Results: Cumulative geographic coverage by S-AEDs was 23% across all periods, assuming uniform access hours. B-AEDs alone versus B-AEDs + S-AEDs covered 20% vs. 34% (weekday), 14% + 30% (Saturday), and 10% + 28% (Sunday). There was no statistically significant difference in 3-minute historical AED accessibility between only B-AEDs and only S-AEDs in standalone deployments (12% vs. 14%). However, when allowing for retrieval of either type of AED in the same scenario, event coverage was improved to 22% (p < 0.001). Conclusion: Deployment of B-AEDs may improve AED coverage but not as a standalone deployment strategy.

Closing with emotion: The differential impact of male versus female attorneys expressing anger in court.

Emotion expression is a key part of trial advocacy. Attorneys are advised to gain credibility with juries by demonstrating conviction through anger expression. In 3 experiments, we tested whether expressing anger in court makes attorneys more effective and whether this depends on their gender. We randomly assigned participants (n = 120 undergraduates) to view a male or female attorney presenting the same closing argument in either a neutral or angry tone (Experiment 1). They reported their impressions of the attorney and how likely they would be to hire the attorney. People used the positive aspects of anger (e.g., conviction, power), to justify hiring an angry male attorney. Yet, they used the negative aspects of anger (e.g., shrill, obnoxious), to justify not hiring a female attorney. We replicated this effect in Experiment 2 with a community sample (n = 294). Experiment 3 (n = 273) demonstrated that the attorney anger by gender interaction generalized to perceptions of effectiveness across a set of additional attorney targets. Finally, a high-powered analysis collapsing across experiments confirmed that when expressing anger relative to when calm, female attorneys were seen as significantly less effective, while angry male attorneys were seen as significantly more effective. Women might not be able to harness the persuasive power of expressing anger in the courtroom, which might prevent female attorneys from advancing in their careers. (PsycINFO Database Record

Simulation of the Effects of Co-Locating Naloxone with Automated External Defibrillators.

INTRODUCTION: Opioid-related overdoses have been steadily increasing over the past decade in the United States. Naloxone is used by first responders to revive overdose victims, but results may be improved by increasing access to and usage of naloxone by bystanders. Automated External Defibrillators (AEDs) are pervasive, recognizable, and publicly accessible. Co-locating naloxone kits with AEDs could increase public naloxone access and usage. However, the impact of co-locating naloxone kits with AEDs is not known. OBJECTIVES: We sought to evaluate the impact of co-locating naloxone kits with AEDs in a simulation study centered on Allegheny County, Pennsylvania. METHODS: Naloxone administration frequency (N = 3,650) at the zip-code level from March 2016 to March 2017 was provided by the Allegheny County Health Department. AED point locations (N = 1,653) were obtained from the University of Pittsburgh's Resuscitation Logistics and Informatics Venture. Zip-code level geospatial analyses were conducted using QGIS and STATA to determine the correlation between AED count and naloxone administrations. AED naloxone kit (N-AED) coverage, based on a maximum "walking-distance" radius of 200 m, was estimated at a zip-code level using the QGIS buffer tool and a custom MATLAB script. Potential impact of N-AEDs was estimated assuming uniform spatial distribution of naloxone administrations. RESULTS: The median (IQR) AED coverage based on a 200 m access radius per zip code was 4% (0-7). The median (IQR) number of naloxone administrations per zip code was 27(7-55). A total of 82 zip codes had data for both AED locations and naloxone administrations. The correlation between number of AEDs and naloxone administrations per zip code was 0.20. Overall, 16% of naloxone administrations were estimated to be covered by an N-AED. CONCLUSION: Using these limited methods, co-locating naloxone with AEDs is not likely to have a standalone impact on preventing overdose fatalities.

When Hurt Heroes Do Harm: Collective Guilt and Leniency toward War-Veteran Defendants with PTSD.

Veterans with post-traumatic stress disorder (PTSD) are at heightened risk for interfacing with the United States legal system as criminal defendants. Two experiments were used to test the hypothesis that American mock jurors would punish a veteran (vs. a civilian) with PTSD for a violent crime less harshly because of their own collective guilt (i.e., the guilt felt for the transgressions of one's in-group) about the veteran's suffering due to war. The participants were United States citizens recruited online (n = 174) who completed a mock-juror experiment involving a violent assault committed by either a veteran or a civilian with PTSD. As predicted, jurors were more lenient toward the veteran (vs. the civilian). For male mock jurors this was explained by their collective guilt for the veteran's war-related suffering. A second study experimentally induced individual and collective guilt about veteran defendants, finding that mock jurors (n = 533) who are less likely to share a salient in-group identity with the veteran (i.e., women, people with lower national identification with the United States) can be induced to feel the requisite guilt to exhibit leniency toward a veteran. Thus, veterans suffering from PTSD may receive more lenient punishment because they elicit a sense of collective guilt in legal decision-makers.

Individual versus group decision making: Jurors' reliance on central and peripheral information to evaluate expert testimony.

To investigate dual-process persuasion theories in the context of group decision making, we studied low and high need-for-cognition (NFC) participants within a mock trial study. Participants considered plaintiff and defense expert scientific testimony that varied in argument strength. All participants heard a cross-examination of the experts focusing on peripheral information (e.g., credentials) about the expert, but half were randomly assigned to also hear central information highlighting flaws in the expert's message (e.g., quality of the research presented by the expert). Participants rendered pre- and post-group-deliberation verdicts, which were considered "scientifically accurate" if the verdicts reflected the strong (versus weak) expert message, and "scientifically inaccurate" if they reflected the weak (versus strong) expert message. For individual participants, we replicated studies testing classic persuasion theories: Factors promoting reliance on central information (i.e., central cross-examination, high NFC) improved verdict accuracy because they sensitized individual participants to the quality discrepancy between the experts' messages. Interestingly, however, at the group level, the more that scientifically accurate mock jurors discussed peripheral (versus central) information about the experts, the more likely their group was to reach the scientifically accurate verdict. When participants were arguing for the scientifically accurate verdict consistent with the strong expert message, peripheral comments increased their persuasiveness, which made the group more likely to reach the more scientifically accurate verdict.

Modeling a novel hypothetical use of postal collection boxes as automated external defibrillator access points.

INTRODUCTION: Optimizing placement of Automated External Defibrillators (AED) can increase survival after an out-of-hospital cardiac arrest (OHCA). Using postal collection boxes (PCB) as locations for AEDs could potentially enhance accessibility and streamline maintenance. In this study, we modeled the hypothetical effects of deploying AEDs at PCB locations. HYPOTHESIS: We hypothesized that PCB-AEDs would increase AED coverage overall and in residential areas, and reduce the distance from OHCA to an AED. METHODS: AEDs in Pittsburgh, PA were identified by the University of Pittsburgh Resuscitation Logistics and Informatics Venture (n=747). PCB locations were obtained from the United States Postal Service (n=479). OHCA locations from 2009 to 2014 were obtained from the Pittsburgh site of the Resuscitation Outcomes Consortium. AED coverage assuming a » mile radius around each AED was estimated for known AEDs, PCB-AEDs (hypothetical AED locations), and known AEDs augmented by PCB-AEDs, both overall and for residential and non-residential zones. Linear distance from each OHCA to the nearest AED was calculated and compared between the sets. RESULTS: The set of known AEDs augmented with PCB-AEDs covered more of the city overall (55% vs 30%), as well as greater proportions of residential (62% vs 27%) and non-residential areas (45% vs 30%). The median distance from OHCA to AED was significantly shorter when known AEDs were augmented with PCB-AEDs (0.12mi vs 0.32mi; p=0.001). CONCLUSION: Augmenting existing publicly accessible AEDs with AEDs deployed at PCBs can increase AED spatial coverage in both residential and non-residential areas, and reduce the distance from AED to OHCA.

One angry woman: Anger expression increases influence for men, but decreases influence for women, during group deliberation.

We investigated whether expressing anger increases social influence for men, but diminishes social influence for women, during group deliberation. In a deception paradigm, participants believed they were engaged in a computer-mediated mock jury deliberation about a murder case. In actuality, the interaction was scripted. The script included 5 other mock jurors who provided verdicts and comments in support of the verdicts; 4 agreed with the participant and 1 was a "holdout" dissenter. Holdouts expressed their opinions with no emotion, anger, or fear and had either male or female names. Holdouts exerted no influence on participants' opinions when they expressed no emotion or fear. Participants' confidence in their own verdict dropped significantly, however, after male holdouts expressed anger. Yet, anger expression undermined female holdouts: Participants became significantly more confident in their original verdicts after female holdouts expressed anger-even though they were expressing the exact same opinion and emotion as the male holdouts. Mediation analyses revealed that participants drew different inferences from male versus female anger, which created a gender gap in influence during group deliberation. The current study has implications for group decisions in general, and jury deliberations in particular, by suggesting that expressing anger might lead men to gain influence, but women to lose influence over others (even when making identical arguments). These diverging consequences might result in women potentially having less influence on societally important decisions than men, such as jury verdicts.
