RESUMEN

Memory for prior contacts has several important applied implications, including contact tracing (for communicable diseases). Incomplete episodic memory reports, which occur across the developmental lifespan but are particularly relevant for children and older adults, may hamper such efforts. Prior research has shown that cognitively informed memory techniques may bolster recall of contacts in adults, but that work has not addressed the developmental efficacy of these techniques. Here we evaluated the effectiveness of such techniques for familiar and unfamiliar contacts within a sample of 9- to 89-year-olds in the context of an ongoing pandemic. The tested memory techniques bolstered recall across the lifespan, irrespective of whether the interview was conducted live with an interviewer or via a self-led interview. Children, emerging adults, and adults did not reveal any differences in memory productivity, however, older adults recalled fewer contacts. Implications for theory and application are discussed.

RESUMEN

OBJECTIVE: We explored whether an educational forensic science informational (FSI) video either alone or with specialized jury instructions would assist mock jurors in evaluating forensic expert testimony. HYPOTHESES: We predicted that the FSI video would help participants distinguish between low-quality and high-quality testimony, evidenced by lower ratings of the testimony and the expert when the testimonial quality was low compared with when it was high. METHOD: Jury-eligible adults (N = 641; Mage = 38.18 years; 77.4% White; 8.1% Latino/a or Hispanic; 50.1% male) watched a mock trial and were randomly assigned to a no-forensic-evidence control condition or to a test condition (i.e., participants either watched the FSI video before the trial or did not and either received specialized posttrial instructions or did not). In the test conditions, a forensic expert provided low-quality or high-quality testimony about a latent impression, and participants rated the expert, their testimony, and the forensic evidence. All participants rendered verdicts. RESULTS: The presence of the FSI video interacted with testimonial quality on ratings of the expert and forensic testimony: In the video-present condition, participants rated the expert in the low-quality testimony condition lower than did participants in the high-quality testimony condition (between-condition differences for credibility: d = -0.52, 95% confidence interval [CI] [-0.78, -0.27]; trustworthiness: d = -0.67, 95% CI [-0.92, -0.42]; knowledgeability: d = -0.54, 95% CI [-0.80, -0.29]). The pattern was the same for the expert's testimony (between-condition differences for convincingness: d = -0.41, 95% CI [-0.66, -0.16]; validity: d = -0.60, 95% CI [-0.86, -0.35]; presentation quality: d = -0.51, 95% CI [-0.76, -0.25]). Participants' ratings in the video-absent condition did not differ on the basis of testimonial quality (ds = -0.07-0.11). The ratings of the print evidence and verdicts were unaffected. Specialized jury instructions had no effect. CONCLUSION: The FSI video may be a practical in-court intervention to increase jurors' sensitivity to low-quality forensic testimony without creating skepticism.

RESUMEN

In this study, we investigate voters' unaided perceptions of whether politicians are lying. We conduct an experiment in which participants attempt to uncover politicians' dishonesty by watching videos of their speeches. We find that verbal cues (specifically, the amount of detail in the speech) and general demeanor cues explain the success (failure) of veracity judgments far better than paraverbal and nonverbal cues. We also find evidence of a truth bias-people are more likely to judge statements to be true than false-despite the political setting, where voters might have been more skeptical. However, gender plays a deterministic role for veracity judgments in political context; female politicians are more likely to be judged as honest.

RESUMEN

This archival study was the first in Sweden, and the first outside of the US and the UK, to apply the (Kelly et al., Psychology, Public Policy, and Law, 9, 165-178, 2013) taxonomy of interrogation methods framework to repeated police interrogations of adult suspects in high-stakes crimes. Audio/video recordings (N = 19) were collected from the Swedish Police Authority of repeated interrogations of three suspects in three criminal cases. The interaction between interrogators and suspects were scored according to the taxonomy framework (Kelly et al., Psychology, Public Policy, and Law, 9, 165-178, 2013; Kelly et al., Law and Human Behavior, 40, 295-309, 2016). First, there was an association between the use of different domains. Rapport and relationship building was moderately and negatively associated with confrontation/competition and presentation of evidence. Moreover, confrontation/competition was moderately and positively related to emotion provocation and presentation of evidence. Second, changes were observed during the interrogations. Presentation of evidence was lower in the beginning than in the middle block. Suspect cooperation was higher in the beginning than both the middle and end blocks. Third, an ordered logistic regression showed that rapport and relationship building were associated with increased suspect cooperation, and confrontation/competition and presentation of evidence were associated with decreased cooperation. The study's results are mostly in line with other taxonomy studies on high-stakes crimes from the US and the UK. The findings are discussed in light of theoretical frameworks, empirical findings, and current police practice. We also highlight the need for further research.

RESUMEN

Background: Low-stakes crimes related to alcohol and/or drugs are common around the world, but research is lacking on police-suspect interactions of such crimes. A large proportion of these suspects are intoxicated during interrogations, and many may have substance use disorder, making them potentially vulnerable to interrogative pressure. Methods: To address this lack of knowledge, the taxonomy of interrogation methods framework (i.e., 60+ interrogation techniques classified into five domains) and a common classification of question types (appropriate vs. inappropriate) were applied in the coding of written police interrogations. Two archival studies, one pilot (Study 1, N = 39) and one main study (Study 2, N = 97) analyzed police interrogations with suspects of alcohol- and drug-related crimes in Sweden. Results: For both Study 1 and 2, suspects showed signs of alcohol and/or drug intoxication, hangover or withdrawal in more than 50% of all interrogations. In Study 2, additional coding indicated that suspects displayed signs of substance use disorder in 57% of the interrogations. The main results from both studies revealed a large number of direct questions asked by the police across all interrogations, and relatively little use of the strategic interrogation techniques from the taxonomy of interrogation methods framework. In fact, when it came to interrogation techniques, law enforcement used more confrontational techniques in their interactions with intoxicated suspects compared to sober suspects. Furthermore, suspects displaying signs of substance use disorder were significantly more cooperative and prone to confess than suspects without indicators of substance use disorder. Conclusion: As the first novel study on low-stakes crime interrogations related to alcohol and/or drugs, the present study provides useful information about current Swedish interrogation practices and areas for improvement. The study results indicate that suspects displaying signs of intoxication or substance use disorder may be more vulnerable during police interrogations. This may in turn have the potential to inform the development of new interrogation policies. Due to the novelty of this research, more studies are needed, both on a national and international level, to examine interrogations in low-stakes crimes further.

RESUMEN

OBJECTIVE: Law enforcement officers often encounter alcohol-intoxicated suspects, suggesting that many suspects are presented with the challenge of grasping the meaning and significance of their Miranda rights while intoxicated. Such comprehension is crucial, given that Miranda is intended to minimize the likelihood of coercive interrogations resulting in self-incrimination and protect suspects' constitutional rights. Yet, the effects of alcohol on individuals' ability to understand and appreciate their Miranda rights remain unknown-a gap that the present study sought to address. HYPOTHESES: Informed by alcohol myopia theory (AMT), we predicted that intoxicated individuals would demonstrate impaired Miranda comprehension compared to sober individuals and those who believed they were intoxicated (but were in fact not; i.e., placebo participants). METHOD: After health screenings, participants completed the Wechsler Abbreviated Scale of Intelligence-Second Edition verbal subtests, rendering a Verbal Comprehension Index (VCI) score. We randomly assigned participants to consume alcohol (n = 51; mean breath alcohol concentration [BrAC] = 0.07%), a placebo condition (n = 44; BrAC = 0.00%), or a sober control condition (n = 41; BrAC = 0.00%). All participants (N = 136) completed the Miranda Rights Comprehension Instruments (MRCI), which measured participants' understanding of the Miranda warnings, recognition of the warnings, appreciation of their rights in interrogation and court settings, and understanding of Miranda-related vocabulary. RESULTS: We found a significant effect of intoxication condition on participants' understanding of Miranda warnings (η²p = .14) and Miranda-related vocabulary (η²p = .05) when controlling for VCI scores. Specifically, intoxicated participants received lower scores for understanding of warnings compared to sober and placebo participants, and lower scores for understanding of Miranda vocabulary compared to sober participants. Alcohol did not significantly impact Miranda rights recognition or appreciation. CONCLUSIONS: Alcohol intoxication may detrimentally impact some facets of Miranda comprehension. Thus, it is important that law enforcement consider refraining from questioning intoxicated suspects. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

RESUMEN

AbstractBackground:Despite the common occurrence of alcohol-related crimes, the Swedish police authority currently lacks national guidelines for dealing with intoxicated victims/witnesses.

Antecedentes: A pesar de que los delitos relacionados con el alcohol son bastante frecuentes, la policía sueca carece en la actualidad de directrices con las que hacer frente a los interrogatorios y entrevistas de víctimas y testigos intoxicados. Método: Esta encuesta trata de explorar los procedimientos de la policía ante personas intoxicadas y comparar los resultados con estadísticas internacionales. Con el fin de facilitar la comparación internacional la encuesta fue ajustada en contenidos a la investigación previa y adaptada al contexto sueco. Se envió una solicitud con un enlace a la encuesta a todas las regiones policiales de Suecia. Resultados: Ciento treinta y tres agentes de policía respondieron que era habitual interactuar con testigos/víctimas intoxicados. Algunos departamentos de policía disponían de directrices locales sobre cómo llevar a cabo entrevistas de investigación con personas intoxicadas pero dependía de cada agente formarse un juicio subjetivo sobre la interacción con estos testigos. Los datos evidenciaron que la alta prevalencia de testigos/víctimas intoxicadas en Suecia es similar a la de Australia, EE. UU. y Reino Unido. Parece que la policía sueca desconoce la investigación sobre cuándo y cómo llevar a cabo entrevistas de investigación con testigos y víctimas intoxicados, un grupo vulnerable. Conclusiones: Se recomienda la colaboración estrecha entre policía e investigadores para crear directrices para la investigación policial con personas intoxicadas.

RESUMEN

BACKGROUND: Prehospital cardiopulmonary resuscitation has commonly been considered ineffective in traumatic cardiopulmonary arrest because traditional chest compressions do not produce substantial cardiac output. However, recent evidence suggests that chest compressions located over the left ventricle (LV) produce greater hemodynamics when compared to traditional compressions. We hypothesized that chest compressions located directly over the LV would result in an increase in return of spontaneous circulation (ROSC) and hemodynamic variables, when compared to traditional chest compressions, in a swine model of traumatic pulseless electrical activity (PEA). METHODS: Transthoracic echocardiography was used to mark the location of the aortic root (traditional compressions) and the center of the LV on animals (n = 34) that were randomized to receive chest compressions in one of the two locations. Animals were hemorrhaged to mean arterial pressure <20 to simulate traumatic PEA. After 5 minutes of PEA, basic life support (BLS) with mechanical cardiopulmonary resuscitation was initiated and performed for 10 minutes followed by advanced life support for an additional 10 minutes. Hemodynamic variables were averaged over the final 2 minutes of BLS and advanced life support periods. RESULTS: Six of the LV group (35%) achieved ROSC compared to eight of the traditional group (47%) (P = .73). There was an increase in aortic systolic blood pressure (P < .01), right atrial systolic blood pressure (P < .01), and right atrial diastolic blood pressure (P = .02) at the end of BLS in the LV group compared to the traditional group. CONCLUSIONS: In our swine model of traumatic PEA, chest compressions performed directly over the LV improved blood pressures during BLS but not ROSC.

RESUMEN

OBJECTIVES: To compare the efficacy of a psychologically-based contact tracing interview protocol to a control protocol that emulated current practices under both interviewer-led and self-led modalities. METHODS: This randomized controlled experiment utilized a 2 × 2 factorial design (Enhanced Cognitive protocol vs Control protocol; Interviewer-led call vs Self-led online survey). Data were collected online (n = 200; Mage = 44; 56.5% female; 79.5% White) during the COVID-19 pandemic (July 2, 2020 - September 15, 2020). RESULTS: The Enhanced Cognitive protocol increased reported close contacts by 51% compared with the Control protocol (d = 0.44 [0.15, 0.71]). This effect was present for both interview modalities and for both identifiable and non-identifiable contacts. The Enhanced Cognitive protocol also increased both the quantity of person descriptors (d = 1.36 [0.87, 1.85]) and the utility of descriptions (r = 0.35 [0.13, 0.53]). CONCLUSIONS: The application of cognitive principles in contact tracing interviews can significantly enhance the quantity and quality of information provided by respondents. Epidemiologists and public health investigators could benefit from utilizing cognitive principles and self-led modalities in contact tracing interviews.

RESUMEN

RATIONALE: It is not uncommon for police to question alcohol-intoxicated witnesses and suspects; yet, the full extent to which intoxication impacts individuals' suggestibility in the investigative interviewing context remains unclear. OBJECTIVE: The present study sought to measure the effect of alcohol-intoxication on interviewee suggestibility by implementing a standardized suggestibility test with participants whose intoxication-state was the same at both encoding and recall. METHODS: We randomly assigned participants (N = 165) to an intoxicated (mean breath alcohol level [BrAC] at encoding = 0.06%, and BrAC at retrieval = 0.07%), active placebo (participants believed they consumed alcohol but only consumed an insignificant amount to enhance believability), or control (participants knowingly remained sober) group. An experimenter then implemented the Gudjonsson Suggestibility Scale (GSS), which produced free recall outcomes (number of correct details and memory confabulations) and suggestibility outcomes (yielding to leading questions and changing answers in response to negative feedback from the experimenter). RESULTS: Intoxicated participants recalled fewer correct details than did placebo and control participants but did not make more confabulation errors. No effects of intoxication on suggestibility measures emerged. CONCLUSIONS: Moderately intoxicated interviewees may not be more suggestible during investigative interviews than sober interviewees. However, before concrete evidence-based policy recommendations are made to law enforcement, further research is needed examining the effects of alcohol on suggestibility in conditions that are more reflective of the legal context.

RESUMEN

BACKGROUND: There currently are no well-defined animal models for traumatic pulseless electrical activity (PEA). Our objective was to develop a swine model of traumatic PEA that would be useful for laboratory research where mortality is an outcome of interest. In this pilot study, we hypothesized that animals that remained in PEA without intervention for a longer period would have increased mortality. MATERIALS AND METHODS: Sixteen Yorkshire swine were alternately allocated to either 5 or 10 min of traumatic PEA without intervention. After the nonintervention period, basic life support (BLS) with mechanical cardiopulmonary resuscitation was initiated and performed for 10 min followed by advanced life support (ALS) for an additional 10 min. Hemodynamic and laboratory values are reported for baseline, posthemorrhage, end of BLS, and end of ALS periods. RESULTS: Mortality in the 10-min PEA group (100%) was higher than the 5-min group (38%) (P = 0.03). Animals in the 5-min group had improved aortic diastolic blood pressure, coronary perfusion pressure, and end-tidal CO2 at the end of both the BLS (P = 0.02, 0.002, and 0.02, respectively) and ALS (P = 0.009, 0.005, and 0.008, respectively). The 10-min animals had increased hyperkalemia at the end of the BLS (P = 0.004) and ALS (P = 0.005) periods. All animals in the 10-min group developed ventricular fibrillation (VF) and 38% of the 5-min animals developed VF (P = 0.03). CONCLUSIONS: In our pilot study of traumatic PEA in a swine model, a shorter period of nonintervention resulted in increased survival, improved hemodynamics during resuscitation, decreased hyperkalemia, and less incidence of conversion to VF arrest.

RESUMEN

To stem the spread of infectious diseases (e.g., Ebola), epidemiologists conduct contact tracing interviews (CTIs) with infected individuals regarding their contacts who may also be infected. These contact tracing interviews, however, may be vulnerable to deadly errors of omission. A promising technique to maximise recall is the Cognitive Interview (CI), which is grounded in psychological theory. In the present study, participants imagined they were infected with meningococcal meningitis and reported their contacts over the previous three days during either a control interview or a CI. To model the cognitive impairment associated with being sick, half of the participants were interviewed while simultaneously completing a cognitive impairment task. The CI generated more contacts than the control interview. However, when the cognitive impairment task was completed, the CI and the control interview performed similarly. We recommend the CI be considered as an alternative to the control interview, particularly if the interviewee is not temporarily impaired due to distraction or illness.

RESUMEN

OBJECTIVES: To compare patient factors and outcomes among children admitted to PICUs from referring versus children's hospital emergency departments (EDs). METHODS: Pediatric patients (<19 years old) admitted to PICUs from referring and children's hospital EDs from July 1, 2011 to June 30, 2013. We compared demographic and clinical factors, including severity of illness as measured by a recalibrated Pediatric Index of Mortality, version 2 score. RESULTS: Of 80 045 children from 109 PICUs, 35.6% were admitted from referring EDs and 64.4% were admitted from children's hospital EDs. Children from referring EDs had higher illness severity (Pediatric Index of Mortality, version 2-predicted risk of mortality, 3.1% vs 2.2%, P < .001), were more likely to be mechanically ventilated within their first hour in the PICU (28.4% vs 23.4%, P < .001), and had higher observed mortality (3.3% vs 2.1%, P < .001). Once adjusted for illness severity and other confounders in a multivariable logistic regression model, there was no difference in the odds of mortality between children from referring and children's hospital EDs (odds ratio: 0.90; 95% confidence interval: 0.79 to 1.02, P = .09) CONCLUSIONS: Children transferred to PICUs from referring EDs had higher illness severity on arrival compared with children admitted from children's hospital EDs. Variations in patient selection for transfer or pretransfer treatment at referring EDs may contribute to the greater illness severity of transferred children. Referring hospitals may benefit from leveraging existing resources to improve patient stabilization before transfer.

RESUMEN

Background: Initial management of urethral injury remains controversial concerning the use of suprapubic urinary diversion and delayed repair, primary open realignment, and primary endoscopic realignment. To our knowledge, we present the first reported case of a penetrating urethral injury because of an animal attack, without concomitant extragenitourinary system involvement, managed entirely endoscopically. Case Presentation: This is a case of an 82-year-old male who presented to the emergency department after an attack by a semidomesticated deer. He presented with a penetrating scrotal injury and gross blood at the meatus. A retrograde urethrogram was performed that revealed a urethral injury. Surgical exploration revealed an isolated 3-cm urethral defect. It was managed with primary endoscopic placement of a urethral catheter and suprapubic tube. Conclusion: Although initial management of urethral injuries remains controversial, an isolated urethral injury after a penetrating trauma because of an animal attack may be safely and effectively managed by primary endoscopic realignment.

RESUMEN

BACKGROUND AND AIMS: There is no current, evidence-based therapy to prevent acute diverticulitis in patients with diverticular disease. Metformin has been shown to have anti-inflammatory effects in a number of disease states, in both animal models and in human observational studies. The potential therapeutic efficacy of metformin in diverticular disease has not been investigated. This study aims to describe the relationship between metformin use and diverticular disease in patients with diabetes mellitus. METHODS: This was a retrospective case-control study. It compared metformin and other hypoglycaemic medication use in diabetic patients with uncomplicated diverticulosis to those with acute diverticulitis. Patients were identified using hospital International Classification of Diseases 10 (ICD-10) data, and radiology, pathology and scanned medical record databases were used to confirm diagnoses and collect all information. Chi square tests were used to determine significance of difference in categorical variables, and Mann-Whitney tests were used for continuous data. RESULTS: There were 174 patients with uncomplicated diverticulosis and 175 patients with acute diverticulitis. A diagnosis of acute diverticulitis was associated with a significantly lower incidence of metformin use, than a diagnosis of uncomplicated diverticular disease (44% compared to 60%, respectively, p = .002). Other oral hypoglycaemic drugs and insulin were not associated with a lower incidence of diverticulitis (p = .12 and p = .24, respectively). CONCLUSION: Metformin use is associated with reduced incidence of diverticulitis in diabetic patients with diverticular disease. The utility of metformin as a therapeutic agent to reduce the risk of diverticulitis in patients with diverticular disease warrants further randomised, prospective, interventional investigation.

RESUMEN

Some innocent suspects rely on the memory of strangers to corroborate their alibis. However, no research has examined whether such potential alibi corroborators can accurately recognize an innocent suspect with whom they previously interacted. We developed a novel alibi corroboration paradigm in which undergraduate students (representing innocent suspects who would later provide an alibi) interacted with naïve university employees (representing potential alibi corroborators). Each student briefly interacted with a different naïve university employee (n = 60), and were also each yoked to a different employee with whom they did not interact (n = 60). Employees were presented 24 hours later with either a single photograph of the student or a six-person array containing a photograph of the student and were asked if they recognized anyone. The majority of employees failed to make a correct recognition of the student. False recognitions, however, were rare. Students exhibited overconfidence that they would be recognized. Findings imply that innocent suspects who rely on strangers to corroborate their alibis may be at risk. Copyright © 2016 John Wiley & Sons, Ltd.
