The purpose of this study was to explore the effect of task demands on children’s singing accuracy. A 2 × 4 factorial design was used to examine the performance of fourth-grade children ( N = 120) in solo and doubled response conditions. Each child sang four task types: single pitch, interval, pattern, and the song “Jingle Bells.” The results indicated that children’s singing accuracy varied by task type, with poorer performance on patterns and songs than on single pitches and intervals. Performance was significantly better for all tasks in the doubled condition than in the solo condition, and a significant interaction indicated task-based performance varied by response mode. Students who indicated some history of private lessons ( n = 54) performed significantly better than those without. Internal reliability using five test items for each type of singing task was satisfactory. Application of the Spearman-Brown formula suggests that a minimum of three items can be included in each task in future research for a reliability coefficient of .75, and four items for a coefficient greater than .80. Performance on these singing tasks was significantly intercorrelated.

To date, conceptual explanations of workload and development of workload measures have been focused primarily on individual workload, the workload of a single operator as they perform a task. Yet, this focus on individual workload does not consider the many situations in which operators are required to collaborate, communicate, and operate as a team to achieve successful performance outcomes. In short, conceptualization and development of team workload measures have lagged behind those of individual workload. In an effort to meet the need for a conceptually-driven team workload measure, Sellers, Helton, Näswall, Funke, and Knott (2014) recently developed the team workload questionnaire (TWLQ). In developing the measure, Sellers and colleagues asked rugby players to rate their workload on TWLQ items. Subsequent exploratory factor analysis suggested that team workload was best described by three latent factors: Taskwork, the demands for task execution on the individual; Teamwork, the demands for team members to cooperate and coordinate with other teammates; and Team-Task Balancing, the demands associated with the need to manage both taskwork and teamwork – reflective of the dual task nature of working within a team. As with any novel measure of workload, it is important to continue evaluation of the measure’s sensitivity to task demands, diagnosticity regarding sources of task demands, and correlation with performance outcomes. Early research with the TWLQ has demonstrated that the measure is sensitive to changes in team task demands and the effects of training in a team UAV control task (Helton, Epling, de Joux, Funke, & Knott, 2015; Sellers, Helton, Näswall, Funke, & Knott, 2015). An additional, critical component of continued validation of the TWLQ is confirmation of the factor structure initially observed by Sellers and colleagues (2014) with data generated from a novel task. Concerns regarding generalizability are particularly germane because of variability in the nature of tasks that teams engage. Whereas some teams are tasked with executing coordinated physical activities, such as is the case in athletic contests (e.g., rugby), the task of other teams is to talk, plan, and decide (e.g., committees; McGrath, 1984). In the current study, we applied the TWLQ in a collaborative choice task (a personnel hiring decision). This team choice task required a high degree of communication, discussion, and joint decision making – team dynamics that contrast sharply with those required during an execution task. In short, the nature of the teamwork in the current study was significantly different from the teamwork evaluated by Sellers and colleagues (2014) when generating the TWLQ. Our goal in this study was to continue validation of the TWLQ by examining its factor structure with a novel dataset derived from a task requiring qualitatively different team dynamics. Confirmatory factor analysis indicated that the present data (N = 144) were a poor fit for the three-factor structure of the TWLQ. Subsequent exploratory factor analysis revealed a much more interrelated model of team workload with no clear division between the three conceptual factors described in the original validation of the TWLQ. This finding indicates that the factor structure of the TWLQ did not generalize to the present team choice task. Given that the duties of operational teams vary, it is critical that future research examine how the conceptual structure of team workload may be altered by task type.

The skill of pitch-matching is a prerequisite for even the most casual musical participation. While singing accuracy has been carefully researched at the elementary level, there has been comparatively less research done with adolescents. The purpose of the study described here was to examine the influence of perceptual ability, task demands, and singing range on the pitch-matching performance of adolescent boys in various stages of the voice change. We found significant differences between certain, inconsistent, and uncertain singers in their perceptual skills and found that a contextual pitch-matching condition was significantly easier than a single-pitch condition. There was no difference by singing range. Future research should explore the progression of these skills longitudinally and continue to examine performance related to different task demands.

The purpose of this study was to examine the effect of repeated attempts at singing accuracy tasks. Test-retest reliability of singing accuracy was examined in a second administration of the test. A secondary purpose was to analyze individual variability in children’s singing accuracy. Test stimuli were designed using five attempts each at a single pitch, interval, and four-note pattern, and song singing. Children aged 6–11 were given the one-on-one singing accuracy test, and an identical form of the test was administered again within 1–6 weeks. Pitch matching items were scored by measuring the deviation in Hertz from the stimuli. The song singing item was scored by singing teachers using an 8-point scale with acceptable inter-rater reliability ( r = .86). Participants’ individual best attempt out of five was equally distributed, with overall performance increasing across subsequent attempts measured in signed cent deviation. A repeated-measures ANOVA with the task type (single, interval, and pattern) and attempt (1, 2, 3, 4, and 5) as the within-subjects variables indicated no main effect for task type ( p = .129), but a significant main effect for attempt ( p < .001, [Formula: see text] = .087). Test-retest reliability was considered high ( r = .69).

Time is a fundamental dimension of human perception, cognition and action, as the perception and cognition of temporal information is essential for everyday activities and survival. Innumerable studies have investigated the perception of time over the last 100 years, but the neural and computational bases for the processing of time remains unknown. First, we present a brief history of research and the methods used in time perception and then discuss the psychophysical approach to time, extant models of time perception, and advancing inconsistencies between each account that this review aims to bridge the gap between. Recent work has advocated a Bayesian approach to time perception. This framework has been applied to both duration and perceived timing, where prior expectations about when a stimulus might occur in the future (prior distribution) are combined with current sensory evidence (likelihood function) in order to generate the perception of temporal properties (posterior distribution). In general, these models predict that the brain uses temporal expectations to bias perception in a way that stimuli are ‘regularized’ i.e. stimuli look more like what has been seen before. Evidence for this framework has been found using human psychophysical testing (experimental methods to quantify behaviour in the perceptual system). Finally, an outlook for how these models can advance future research in temporal perception is discussed.

The cover photograph for this issue of Public Voices was taken sometime in the summer of 1929 (probably June) somewhere in Sunflower County, Mississippi. Very probably the photo was taken in Indianola but, perhaps, it was Ruleville. It is one of three such photos, one of which does have the annotation on the reverse “Ruleville Midwives Club 1929.” The young woman wearing a tie in this and in one of the other photos was Ann Reid Brown, R.N., then a single woman having only arrived in the United States from Scotland a few years before, in 1923. Full disclosure: This commentary on the photo combines professional research interests in public administration and public policy with personal interests—family interests—for that young nurse later married and became the author’s mother. From the scholarly perspective, such photographs have been seen as “instrumental in establishing midwives’ credentials and cultural identity at a key transitional moment in the history of the midwife and of public health” (Keith, Brennan, & Reynolds 2012). There is also deep irony if we see these photographs as being a fragment of the American dream, of a recent immigrant’s hope for and success at achieving that dream; but that fragment of the vision is understood quite differently when we see that she began a hopeful career working with a Black population forcibly segregated by law under the incongruously named “separate but equal” legal doctrine. That doctrine, derived from the United States Supreme Court’s 1896 decision, Plessy v. Ferguson, would remain the foundation for legally enforced segregation throughout the South for another quarter century. The options open to the young, white, immigrant nurse were almost entirely closed off for the population with which she then worked. The remaining parts of this overview are meant to provide the following: (1) some biographical information on the nurse; (2) a description, in so far as we know it, of why she was in Mississippi; and (3) some indication of areas for future research on this and related topics.

BDSM encompasses a range of practices—bondage and discipline (BD), dominance and submission (DS), sadism and masochism (SM)—involving the consensual exchange of power in erotic contexts. This chapter provides an overview of scholarship on BDSM, drawing on the history of academic studies of the phenomenon, ranging from the psychology of perversion, the sociology of deviance, and the feminist “sex wars” to more recent ethnographic and phenomenological turns. The chapter focuses on the importance of discourse and affect for making sense of BDSM, both for those who seek to analyze the phenomenon and for practitioners themselves. Drawing on ethnographic research and other data, the chapter shows how language and discourse are key to answering interconnected questions about the semiotics and phenomenology of BDSM (what these practices mean and how practitioners experience these practices affectively). Thus, a potential “linguistic turn” in BDSM studies is essential for future research on this erotic minority.

This chapter offers a historiographic survey of country music scholarship from the publication of Bill C. Malone’s “A History of Commercial Country Music in the United States, 1920–1964” (1965) to the leading publications of the today. Very little of substance has been written on country music recorded since the 1970s, especially when compared to the wealth of available literature on early country recording artists. Ethnographic studies of country music and country music culture are rare, and including ethnographic methods in country music studies offers new insights into the rich variety of ways in which people make, consume, and engage with country music as a genre. The chapter traces the influence of folklore studies, sociology, cultural studies, and musicology on the development of country music studies and proposes some directions for future research in the field.

Morality and gender are intersecting realms of human thought and behavior. Reasoning and action at their intersection (e.g., views of women’s rights legislation) carry important consequences for societies, communities, and individual lives. In this chapter, the authors argue that children’s developing views of morality and gender reciprocally shape one another in important and underexplored ways. The chapter begins with a brief history of psychological theory and research at the intersection of morality and gender and suggests reasons for the historical failure to view gender attitudes through moral lenses. The authors then describe reasons for expecting morality to play an important role in shaping children’s developing gender attitudes and, reciprocally, for gender attitudes to play an important role in shaping children’s developing moral values. The authors next illustrate the importance and relevance of these ideas by discussing two topics at the center of contentious debate in the United States concerning ethical policy and practice: treatment of gender nonconformity and gender-segregated schooling. The chapter concludes with suggestions for future research.

AbstractMusic has been steadily rising up the historical agenda, a product of the emergence of sound studies, the history of the senses, and a mood of interdisciplinary curiosity. This introductory article offers a critical review of how the relationship between music and politics has featured in extant historical writing, from classic works of political history to the most recent scholarship. It begins by evaluating different approaches that historians have taken to music, summarizes the important shifts in method that have recently taken place, and advocates for a performance-centered, contextualized framework that is attentive to the distinctive features of music as a medium. The second half examines avenues for future research into the historical connections between music and politics, focusing on four thematic areas—the body, emotions, space, and memory—and closes with some overarching reflections on music's use as a tool of power, as well as a challenge to it. Although for reasons of cohesion, this short article focuses primarily on scholarship on Britain and Ireland in the eighteenth and nineteenth centuries, its discussion of theory and methods is intended to be applicable to the study of music and political culture across a broad range of periods and geographies.
