Theoretical and legal issues related to choice blindness for voices

Purpose. To examine whether choice blindness occurs for auditory stimuli, namely voices. Methods. One hundred participants listened to three pairs of voices and had to decide each time which one they found more sympathetic or sounded more criminal. After they made a choice, participants were presented with the chosen voice again and had to match it to a face. However, during the second trial, participants were actually presented with the voice they had previously not chosen. Results. Only 19% of the participants detected this change concurrently, an additional 10% detected it retrospectively. This indicates that choice blindness transfers to auditory stimuli. Whether participants had previously evaluated sympathy or criminality of the voices had no effect on choice blindness. Conclusions. The study shows that choice blindness is a robust phenomenon that can also be elicited when auditory stimuli are employed. Implications for earwitness testimony and expert witnesses in the context of forensic speech analysis are discussed.     

Re‐Claiming Disability: Identity,Procedural Justice,and the Disability Determination Process

This research highlights the crucial role of an intimate link between a disabled person's self‐identity and the perceived fairness of legal procedures. In doing so, it brings to the foreground a wholly ignored aspect of procedural justice. Earlier researchers have failed to delve into the role identity politics plays in the relationship between the institutions and the beneficiaries of their services, and the way different members of a group understand and define themselves. This research explores the way people with disabilities in the United States, with different kinds of disability identities, experience and evaluate the procedure of claiming Social Security benefits. The findings suggest that disabled people who identified with the social model of disability (as opposed to the medical‐individual models) hold a critical view of the procedure for retaining benefits. They felt they had no control over it, could not voice their opinions, were mistreated by representatives, and had to present an image that was not necessarily true of their disability. They also saw the procedure as discouraging them from participating fully in the labor market, and consequently integrating better in society, an idea that was not present among disabled people who identify with medical‐individual models. Exposing this relationship between the way people perceive themselves and the way they experience and evaluate legal procedures can contribute to the creation of better policies, while improving communication between the state and members of the disability community, along with other marginalized groups.     

Analysis of motivation in people with mild learning disabilities (mental handicap) who set fires

Abstract

Ten people with mild learning disabilities (mild mental handicap) who had all set rues and had been admitted to a hospital facility for people with challenging behaviours were interviewed about their perceptions of events, feelings and cognitions prior to and after setting fins. They were also asked to rate their excitement/upset in a series of fire-related situations. Results showed that people could identify reliably the events, feelings and cognitions prior to fire-setting but were less reliable at identifying consequences. Most commonly, people had felt angry prior to setting fires but it was also common to feel not listened to, sad or depressed. Multiple factors were relevant for most people. Some people identified the excitement of the rue as relevant and these people gave the highest ratings on the fire-related situations schedule and scored higher than controls on this schedule. Implications for treatment are discussed.     

The true servant: Self-definition of male domestics in an Italian city (Bologna, 17th–19th centuries)

Some historians have classed as servants only people living with their masters; some have excluded farm servants; some have included married domestics living with their own families. The archive of the Bolognese Confraternity of San Vitale, also known as Università dei Servitori, is analyzed in this article to show how one group of servants defined a “true” servant. Their solution was to exclude from their association people who performed what they deemed “filthy” tasks. They also excluded women, giving us a particular insight in the history of gender and masculinity. In their view, the “true” servants were bourgeois (and locally born) men rather than lower class (migrant) women who are often identified as the stereotypical servants. Moreover, most members of the association were married, they had their own families in Bologna and did not always live with their masters. This makes possible the analysis of married male servants living with their own families, a category of servant that has received less attention than life-cycle servants.

Not enough help for themselves--the risk of physicians to commit suicide

Physicians seem unwilling to deal with their own suicidal problems professionally. Suicide is a repressed topic. According to international studies, medical students and physicians are clearly over-represented among suicide victims. Committing suicide stands in sharp contrast to the positive image physicians enjoy as competent, strong helpers transmitting positive energy. Various studies and meta-analyses show that physicians use knowledge specific to their profession and are therefore "more successful" than the general population in committing suicide. Moreover, the data reveal a number of risk factors specifically correlating with medical practice. This is confirmed by an increased number of suicides during medical training and professional life in comparison with the general population. Gender-specific analyses show an even higher suicide risk for female physicians. In this context it cannot be excluded that out of "professional respect" cardiovascular causes of death are sometimes falsely documented in death certificates instead of suicide. Despite their special education, physicians are not very good at diagnosing their own emotional disorders and asking colleagues for adequate professional help. They rather tend to camouflage their own psychological problems also because they are afraid of occupational and personal discrimination.     

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.     

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。

Physically violent mothers are a reason for young people's leaving home

In a qualitative study, 302 homeless young people (aged 12 to 20 years) were asked to discuss their reasons for leaving home. Some 103 youth cited physical violence by a parent or stepparent, and of these, 39 cited their mother's or stepmother's violence as the reason for leaving home. Females were more likely than males to report being the target of violence by their mother; however, the converse was true for stepmothers. Several discrete reasons for maternal violence were identified, including maternal personal characteristics and behaviors, issues associated with blended families, or young people's own behavior. In some cases, young people reported violence by both parents. Their attributions of maternal violence centered on a single dimension of the mother/stepmother or her relationship with a partner. They rarely discussed the contribution that they had made to the conflict or acknowledged the social context that may have been a catalyst for violence.     

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.     

Recognition of previous eyewitness testimony from an altered interrogation protocol: Potential effects of distortions

Abstract

The effect of protocol presentation on witnesses’ tendency to point out errors in a transcribed version of their verbal testimony was examined in two experiments. Participants were shown a film depicting a robbery and were subsequently questioned. In the process of typing out the testimony, there were six distortions entered into the protocol. When participants were asked to check the content for approval, they either listened to the experimenter reading the protocol out aloud, or read it on their own. The results showed that witnesses who had listened to the content being read to them pointed out significantly fewer distortions, and suggest that protocol presentation may have important implications for the justice system.     

The Voice of the Community in Private Law Discourse

Formalist private lawyers, with their view of law as an autonomous sphere and their emphasis upon allocative rules, tend to approach the issue of the harmonisation of private law in Europe with the following question: are the substantive rights and remedies of private individual actors sufficiently similar within each of the Member States to allow for the unification of autonomous private legal systems. Here the issue is essentially one of terminology. While sceptical voices maintain that formal private law is also a more complex matter of interrelated procedures and practices, many formalists conclude that whilst the terms of rights and remedies may differ slightly throughout Europe, there is sufficient substantive convergence to allow for harmonisation. However, lawyers of a sociological persuasion who see private law as being contingent upon society Ð a process reflexively and recursively facilitating economic activities and responding to social change Ð consider harmonisation to be dependent upon the harmonisation of market practices themselves. This paper, one of the most subtle of sociological contributions, tackles this issue with an innovative eye to the increasing blurring of the distinction between public and private concerns. The voice of Europe is the voice of a political collective and theoretically, under the once sacrosanct paradigm of the public/private divide, should not be heard within the 'individualistic' sphere of private law. However, just as national private law judges are generally responding to social concerns and are seeking to integrate collective voices within a once 'atomised' realm, so too are they taking note of the political voice of Europe: attempting to respond to the desire for integration and harmonisation within their jurisprudence.     

Voice identification by human listeners: On earwitness reliability

This paper reviews what is currently known about voice identification by human listeners. Our own experimental data from a four-year research program into this topic is used to elucidate, support, and in some cases to contradict published work into the effects on voice identification of such factors as speech sample size and quality, voice disguise, delay in holding voice identification sessions, incidental as opposed to intentional memory for voices, the effects of the age of the witness, training in specific modes of encoding voices, and the relationship between objective accuracy and subjective feelings of certainty of correctness. It is concluded that the caution and suspicion currently accorded to visual identification must be extended also, and perhaps more so, to voice identification.Part of the research discussed in this paper was conducted under the auspices of a grant from the British Home Office to the author and Ray Bull. The author would like to thank the issue editor for his very useful comments on an earlier draft of this paper, and Harriet Rathborn for running many of the experiments.     

Parental Responsibility

Families are the first level in our society with the responsibility and authority to prevent substance abuse by their children and to intervene if their children become involved. They are responsible for exemplifying and teaching the values of drug-free lives for their children. These responsibilities are more than the practice of good parenting skills. They are inherent responsibilities recognized by society and by law. Supported in their efforts by community services, parents must be encouraged to fulfill their roles and to recognize themselves as accountable.

Aggressive and Non-Aggressive schizophrenics: Symptom profile and neuropsychological differences

Abstract

The present experiment examined the ability of fifty-two uniformed police officers to detect deception. The experiment differed from previous experiments into detecting deceit because of its high stake lies scenario. The judges were exposed to videotaped press conferences of people who were asking the general public for help in finding their relatives or the murderers of their relatives. They all lied during these press conferences and they all have been found guilty of killing their own relatives. The judges did not perform better than could be expected by chance. Additional analyses showed that accuracy was unrelated to confidence, age, years of job experience in the police force, or level of experience in interviewing suspects. There was, however, a significant positive correlation between having experience in interviewing suspects and being confident in detecting deception. Finally, men were better at detecting deception than women.     

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.     

My Life for A Voice: The Influence of Voice on Health-Care Decisions

Are people willing to give up affordable healthcare and future years of their lives in exchange for having a voice in healthcare decision-making? Drawing upon research on the psychology of justice, we claim that the fairness of healthcare decision-making procedures, expressed by the availability of voice, can be more important than critical health-related outcomes. We examined this proposition using a forced-choice paradigm that required participants to choose between voice and better healthcare outcomes (affordable healthcare and greater life expectancy). Findings from three studies revealed that people maintain a strong preference for voice even at the expense of tangible healthcare outcomes. In study 1, participants preferred a healthcare plan that offered them a voice when it was $3,000–$12,000 more costly than a plan that did not offer such voice privileges. In study 2, participants preferred a voice plan to a no-voice plan when the no-voice plan was 5–20 years greater in its average life expectancy compared with the voice plan. In study 3, which used a more demographically diverse, non-student sample, the preference for the voice plan persisted across all conditions, even when the no-voice plan was 25 years greater in its life expectancy, and even when participants’ expected to personally live longer under the no-voice plan. These results are explained by participants’ expectation to enjoy better personal healthcare outcomes and greater autonomy when afforded voice. These findings demonstrate the importance of voice in hypothetical decision-making relevant to policy-making.
