Real Personal Uncertainty Induced by Means of Task-Related Feedback: Effects on Reactions to Voice and No-Voice Procedures

Building and extending on research on uncertainty management and voice and no-voice procedures, we examine how real personal uncertainty moderates the way in which people react to getting or being denied an opportunity to voice one??s opinions about decisions to be made. Specifically, results of two experiments show that conditions in which participants receive task-related feedback that induces personal uncertainty (versus conditions that produce more personal certainty) lead to stronger effects of voice and especially no-voice procedures on participants?? procedural fairness judgments (Experiments 1 and 2). Findings also reveal that in these conditions stronger effects of voice and particularly no-voice procedures can be found on participants?? anger about the way they have been treated, especially when participants are predisposed to react in intense terms to affect-related events (Experiment 2). Implications for the literature on uncertainty management and the social psychology of voice and no-voice procedures are discussed.     

Revisiting the Instrumentality of Voice: Having Voice in the Process Makes People Think They Will Get What They Want

Research on procedural justice has found that processes that allow people voice (i.e., input) are perceived as fairer, and thus elicit more positive reactions, than processes that do not allow people voice. Original theorizing attributed these effects to beliefs that the provision of voice enhances people’s sense of process control, which people were assumed to value because it impacts their perceived likelihood of receiving desired outcomes (the instrumental perspective of procedural justice). Subsequent research questioned this perspective, arguing that outcome expectations do not account for the effects of voice. However, this subsequent research failed to directly examine the interplay of voice, outcome expectations, and reactions. The current studies revisit and extend research on this topic by asking whether manipulations of voice act as shared circumstance effects. Confirming an untested implication of the instrumental perspective, we show that giving everyone voice increases their belief, ex-ante, that they are likely to win an upcoming competition. However, this instrumental belief accounts for only part of the effects of voice on perceived procedural fairness and on general reactions to outcomes. Results suggest that voice does indeed have instrumental significance, an implication not adequately recognized in current justice theorizing. However, this instrumentality does not, by itself, explain why people value having a voice in processes that affect them.     

Economic Burden of Child Exposure to Intimate Partner Violence in the United States

Because the effects of children’s exposure to intimate partner violence (IPV) carry long lasting consequences for the affected children, IPV exposure may impose a significant economic burden to localities, states, and society at large, made explicit over the victim’s lifetime and over a wide range of behaviors and outcomes, including use of social services, health and healthcare utilization, educational outcomes, workforce productivity, and criminal behavior. While much research has been conducted on the effect of IPV exposure on multiple short- and long-term outcomes, no research to date has examined the economic burden associated with IPV exposure. Using an incidence-based approach, we estimated the aggregate discounted costs associated with healthcare spending, criminal behavior, and labor market productivity accrued by a 20-year-old victim in 2016 projected to the age of 65, applying a 3% discount rate. The average lifetime costs derived from childhood IPV exposure are estimated to be over $50,000 per victim (2016 U.S. dollars) due to increased healthcare costs ($11,000), increased crime costs ($14,000), and productivity losses ($26,000). Over an annual birth cohort of young adults, these costs amount to over $55 billion nationwide. IPV exposure imposes a substantial economic burden to society at large in the form of increased healthcare costs, increased crime costs, and reduced productivity. This study offers an explicit quantification of substantial lifetime costs, which should encourage policy makers to redouble efforts to reduce the incidence of IPV and successfully ameliorate its effects on IPV-exposed children.     

Children's identification of unfamiliar voices on both target-present and target-absent lineups

ABSTRACT

A robust finding from the eyewitness literature is that children are as accurate as adults on target-present lineups from the age of five years, whereas they continue to make an erroneous false positive identification from a target-absent lineup up until around fourteen years of age (Pozzulo, J. D., & Lindsay, R. C. L. (1998). Identification accuracy of children versus adults: a meta-analysis. Law and Human Behavior, 22(5), 549–570). The current study explores whether the same pattern occurs when voices are used instead of faces. A total of 334 participants from six age groups (6–7-year-olds, 8–9-year-olds, 10–11-year-olds, 12–13-year-olds, 14–15-year-olds and adults) listened to a 30 second audio clip of an unfamiliar voice and were then presented with either a six person target-present or target-absent voice lineup. Overall, participants were more accurate with target-present than target-absent lineups. Moreover, performance on target-present lineups showed adult-like levels of attainment by 8–9 years of age. In contrast, performance on target-absent lineups was extremely poor, with all age groups tending to make a false identification. Confidence was higher when participants made correct rather than incorrect decisions for both types of lineup and this did not change with increasing age. Given these results, both child and adult earwitness evidence needs to be treated with considerable caution.     

Belief in a Just World and Commitment to Long-Term Deserved Outcomes

We investigated whether people need to believe in a just world in part because such a belief helps people to work toward long-term goals and to do so in such a way that they are deserved. We assessed participants' long-term goal focus and also their commitment to deserving their outcomes (via a psychopathy scale). In a second session, participants were then exposed to a victim whose situation did or did not contradict a belief in a just world. When the victim's situation contradicted a belief in a just world, the greater the participants' tendency to focus on long-term outcomes, the more they blamed the victim for her misfortune; but this relation only occurred for participants with a strong commitment to deserving their outcomes (i.e., those low in psychopathy). The results are consistent with our argument that, given the function of the belief in a just world proposed in this article, people would have a greater need to preserve the belief (e.g., by blaming victims of injustice) the greater their investment in long-term and deserved outcomes.

Procedural decisions in intergroup conflict situations: The influence of hierarchical group membership

A review of research on procedural and distributive justice shows that whereas distributive justice research has examined people's actual choice of outcomes, procedural justice research has paid little attention to the investigation of people's actual choice of procedures. In the present paper, three experiments are presented, all investigating people's actual choice of procedures. In all three experiments, participants were in a middle-management position where their subordinates demanded an opportunity to voice their opinion, while their superiors demanded that the subordinates should not be allowed voice. In Experiments 1 and 2 it was found that participants who were induced to identify with the low hierarchical group (subordinates) allowed more voice than participants who were induced to identify with the high hierarchical group (superiors), but that the effect of hierarchical group membership was absent when maximizing performance (Experiment 1) or participative values (Experiment 2) were explicitly emphasized. In Experiment 3 it was found that the effect of hierarchical group membership on procedural decision making was also evident in persons who progressed from identifying with both hierarchical groups to identifying with one hierarchical group. In the discussion it is argued that cross-fertilization between the fields of procedural and distributive justice will deepen our understanding of social justice in general.     

Validity Beliefs and Ideology Can Influence Legal Case Judgments Differently

Jurors sometimes enter a case both with prior beliefs about its likely validity and with more general ideologies that are relevant to the case. Although prior validity beliefs may serve as heuristics, directly biasing decisions when cognitive capacity is low, we hypothesized that ideology may bias systematic thought even when cognitive capacity is high. This experiment studied simulated individual juror decisions in a sex-discrimination case, measuring validity beliefs about such cases as well as feminist ideology, and exposing participants to 1 of 3 case versions under time pressure or no time pressure. Validity beliefs had a direct, heuristic impact on judgment only under time pressure. However, feminist ideology had a mediated influence on judgment via valenced thoughts about the evidence, even under no time pressure. Also, people with initially proplaintiff beliefs judged a woman's sex-discrimination suit more negatively than did prodefendants if the evidence was weak. The results suggest that when jurors can fully process information, validity expectancies might backfire if not supported by case evidence, but ideology can have a more pervasive influence on the decision-making process.     

Risk factors for stalking violence,persistence, and recurrence

This study used a retrospective design to investigate risk factors associated with violence during a stalking episode, persistence (increased duration of stalking) and recurrence (multiple subsequent separate stalking episodes) in 157 people (91% male, mean age 35 years) with an established history of stalking behaviour. Results showed that diverse risk factors are associated with different types of stalking outcomes. Consistent with previous research, stalking violence was more likely to occur when the victim was an ex-intimate, when explicit threats had been made and where there had been previous property damage (AUC = .74). Personality disorder, older age, criminal versatility, a prior acquaintanceship and erotomanic delusions (AUC = .75) predicted stalking recurrence. Finally, previous acquaintanceship, the presence of delusional beliefs and the absence of a history of physical or sexual violence were associated with stalking persistence. These results clearly show that effective assessment and management of stalking requires consideration of different stalking outcomes and the diversity of associated risk factors.     

正常、大声两种说话状态下语音的声学差异及对声纹鉴定的影响

本文主要通过对正常、大声两种说话状态下的普通话中三个单元音[a]、[i]、[u]的声强、时长、基频、谐波振幅差值、共振峰等声学参数的分析,综合比较了各参数的变化规律,发现大声说话时的语音并非正常语音的简单放大,二者不仅在声强上存在差别,同时在频率域上也发生了重要变化。同一人不同状态下发音的频谱特征差异性较大,同种状态下发音的相似性、可比性较强,为此,声纹鉴定中应尽量选取状态相同的语音进行比对。     

Affirmative Action in an Institutional Context: The Antecedents of Policy Preferences and Political Support

This study broadens the framework within which the psychology of support for affirmative action policies is examined to include the institutional framework within which such policies are developed and implemented. This broader framework includes concern with electoral support for those who implement affirmative action policies, as well as considering the impact of implementing such policies on the overall legitimacy of government. It also includes evaluations of the fairness of the two key social institutions shaping such policies—government authorities and markets. The results of a survey of Americans suggest that this institutional framework had an important influence on reactions to affirmative action policies that was distinct from direct reactions to policies themselves. In particular, people were more supportive of policies intervening in markets when they believed that markets represented unfair social allocation procedures. Those politicians who supported such policies received greater electoral support when people viewed market procedures as being unfair and when they felt that government decision-making procedures were fair. Evidence suggests that outcomes did not directly shape electoral support or judgments about the legitimacy of government.     

Domestic violence and high conflict are not the same: a gendered analysis

In child custody decision-making experiences of domestic violence and high conflict are not the same. Legislative reform has not yet been guided by the parent voice to inform differentiated responses that keep women and children safe. Available literature in child custody decision-making focuses on outcome research regarding children’s adjustment and well-being. Debates about types of post-separation arrangements have yet to find agreement in three under-researched areas: (a) high conflict, (b) domestic violence; and (c) children under four. Yet, Canadian legislation supports shared parenting arrangements that privilege the dominant, powerful parent in situations of domestic violence. Based on a Canadian study that explores the parent perspectives and experiences of child custody decision-making, this paper privileges a sub-group of participants; five women, all survivors of domestic violence; defined here as both physical violence and coercive control. Data collection includes one-on-one tape-recorded interviews. Thematic analysis reveals that shared parenting is neither the goal, nor does it meet the needs of these women. The findings illuminate the importance of differentiating parent experience as distinct groups, and reinforces the notion of the state’s role in the reproduction of gendered power. Legislative reform and collaborative community practices are critical to facilitate healthy differentiated responses.

Mock terrorists decisions’ concerning use of the internet for target selection: a red-team approach

In this study we sought to identify which locations appear more, or less, attractive to a terrorist in planning an attack and to investigate what attributes of those locations influence preferences. A sample of undergraduate university students (N?=?147) were given the role of terrorists, and provided with five potential attack locations, including a pedestrian mall, a shopping center, a train station, a university and an airport. After using the Internet to learn about the target locations, participants placed the locations in rank-order from most to least preferred as targets and indicated why they had selected those targets. Results showed both a clear rank-order of target preferences: locations perceived as being more crowded were more preferred, while locations with a greater security presence were less preferred. Results also demonstrated a moderate positive correlation between the amount of online information viewed for a specific location and the preference for that location as a terrorist target, where participants who viewed more online content for a particular location were more likely to also prefer that location as a terrorist target. Findings from this study can potentially be used to reduce the likelihood of a terrorist attack occurring on specific locations, by altering the publicly available information on that location regarding the security and how crowded that location is.     

Voice stress evaluators and lie detection

Proponents of vocal stress analysis systems argue that they are able to detect spoken deception by analysis of "stress" in the voice signal. Presumably, they do so by examining traces made by laryngeal microtremors which, they claim exist in the voice, are associated with stress, and ultimately are associated with lying. However, most research that seeks to identify the relationships between microtremors and laryngeal function has produced negative results, and data on the ability of voice analyzers to detect stress from speech--or to identify spoken deception--have been negative or "mixed" in nature. Since perspectives based on available results leave a number of questions unanswered, a series of experiments has been undertaken. The first was focused on the basic acoustic/temporal correlates of stress in voice (the subject of an earlier report), the second on examination of stress by commercial voice analyzers, and the third on the detection of relatively high-risk lies by this same type of voice analysis procedure. It was found that correct stress/nonstress identifications occurred only at chance levels; the lie/nonlie identification scores were quite similar with professional "examiners" performing at about the same level of accuracy as other auditors. The following review is divided into two parts: a history of the controversy and a presentation of the two cited experiments.     

Role of voice in the legal process*

As communities face unrest and protest because of perceived racial bias and decreased trust and confidence in the criminal justice system, it is critical to explore mechanisms that foster institutional legitimacy. Voice is a central element in the procedural justice framework because it is anticipated to promote process control as well as a shared understanding between institutions and communities. As a concept, however, voice is undertheorized. Measures of voice used in legitimacy research may result in oversimplification of the concept, not fully capturing the struggles disadvantaged people face in trying to exercise influence in the court system. Through the use of rich data from qualitative interviews with youth and families involved in the juvenile justice system and in‐depth observations of juvenile court events, we explore what voice is, the mechanisms through which people try to assert voice, and how voice matters in the legal process. Respondents sought voice for many reasons, including to validate their experiences, to affirm their membership in a community, and to assert concerns about perceived police misconduct. Contrary to traditional conceptualizations of voice as a static event (e.g., having voice or not having voice), voice was a process of negotiating dialogue between court officials and court participants throughout the legal process.     

Using sensitive data to prevent discrimination by artificial intelligence: Does the GDPR need a new exception?

Organisations can use artificial intelligence to make decisions about people for a variety of reasons, for instance, to select the best candidates from many job applications. However, AI systems can have discriminatory effects when used for decision-making. To illustrate, an AI system could reject applications of people with a certain ethnicity, while the organisation did not plan such ethnicity discrimination. But in Europe, an organisation runs into a problem when it wants to assess whether its AI system accidentally discriminates based on ethnicity: the organisation may not know the applicants’ ethnicity. In principle, the GDPR bans the use of certain ‘special categories of data’ (sometimes called ‘sensitive data’), which include data on ethnicity, religion, and sexual preference. The proposal for an AI Act of the European Commission includes a provision that would enable organisations to use special categories of data for auditing their AI systems. This paper asks whether the GDPR's rules on special categories of personal data hinder the prevention of AI-driven discrimination. We argue that the GDPR does prohibit such use of special category data in many circumstances. We also map out the arguments for and against creating an exception to the GDPR's ban on using special categories of personal data, to enable preventing discrimination by AI systems. The paper discusses European law, but the paper can be relevant outside Europe too, as many policymakers in the world grapple with the tension between privacy and non-discrimination policy.     

Voice disguise and automatic speaker recognition

In this paper a newly developed Forensic Automatic Speaker Recognition System (FASRS) was introduced and the effect of 10 types of voice disguises that are common in forensic casework on the performance of this system was studied. In this study 10 types of disguised voices and normal voices from 20 male college students were used as test samples. Each disguised voice was compared with all normal voices in the database to make speaker identification and speaker verification. The result of speaker recognition is summarized and the influence of voice disguises on the FASRS is evaluated.
