Perceptions of human attractiveness comprising face and voice cues

In human mate choice, sexually dimorphic faces and voices comprise hormone-mediated cues that purportedly develop as an indicator of mate quality or the ability to compete with same-sex rivals. If preferences for faces communicate the same biologically relevant information as do voices, then ratings of these cues should correlate. Sixty participants (30 male and 30 female) rated a series of opposite-sex faces, voices, and faces together with voices for attractiveness in a repeated measures computer-based experiment. The effects of face and voice attractiveness on face-voice compound stimuli were analyzed using a multilevel model. Faces contributed proportionally more than voices to ratings of face-voice compound attractiveness. Faces and voices positively and independently contributed to the attractiveness of male compound stimuli although there was no significant correlation between their rated attractiveness. A positive interaction and correlation between attractiveness was shown for faces and voices in relation to the attractiveness of female compound stimuli. Rather than providing a better estimate of a single characteristic, male faces and voices may instead communicate independent information that, in turn, provides a female with a better assessment of overall mate quality. Conversely, female faces and voices together provide males with a more accurate assessment of a single dimension of mate quality

Objective and subjective comprehension of jury instructions in criminal trials

It would seem important that jury instructions are clear and comprehensible to jurors if they are to effectively carry out their responsibility in criminal trials. Research suggests, however, that jurors may not fully understand instructions despite reporting high levels of comprehension. The current study (N = 33) surveyed jurors who had recently served on a jury to assess their level of comprehension and the factors that contributed to their decisions. It was found that a substantial proportion of jurors were mistaken about directions relating to beyond reasonable doubt and burden of proof. It also was found that higher levels of self-reported comprehension were associated with self-reported reliance on additional factors to arrive at a decision, and a more positive evaluation of the prosecutions' case. Overall, although jurors report that they understand directions, they do not appear to use those directions in arriving at a decision. Subjective comprehension appears to be an important factor in understanding the effect of directions on jurors

Clinical implications of chloroquine and hydroxychloroquine ototoxicity for COVID-19 treatment: A mini-review

At this time of the COVID-19 pandemic, potentially effective treatments are currently under urgent investigation. Benefits of chloroquine and hydroxychloroquine for the treatment of COVID-19 infection have been proposed and clinical trials are underway. Chloroquine and hydroxychloroquine, typically used for the treatment of malaria and autoimmune diseases, have been considered for off-label use in several countries. In the literature, there are reports of ototoxic effects of the drugs causing damage to the inner ear structures, which then result in hearing loss, tinnitus, and/or imbalance. This mini-review represents a summary of the findings from a systematic search regarding ototoxicity of chloroquine and hydroxychloroquine in the published literature. The characteristics of sensorineural hearing loss and/or tinnitus after chloroquine or hydroxychloroquine treatment can be temporary but reports of persistent auditory and vestibular dysfunction exist. These are not frequent, but the impact can be substantial. Additionally, abnormal cochleovestibular development in the newborn was also reported after chloroquine treatment in pregnant women. The suggested dose of chloroquine for COVID-19 infection is considerably higher than the usual dosage for malaria treatment; therefore, it is plausible that the ototoxic effects will be greater. There are potential implications from this review for survivors of COVID-19 treated with chloroquine or hydroxychloroquine. Patient reports of hearing loss, tinnitus, or imbalance should be noted. Those with troublesome hearing loss, tinnitus and/or imbalance are encouraged to be referred for hearing evaluation and interventions once they are stable. Clinical trials of chloroquine or hydroxychloroquine should also consider including audiological monitoring in the protocol

Prevalence and characteristics of spontaneous tinnitus in 11 year old children

Objective: To estimate the prevalence of spontaneous tinnitus in 11-year-old children. Design: A prospective UK population-based study. Study sample: A total of 7092 children from the Avon longitudinal study of parents and children (ALSPAC) who attended the hearing session at age 11 years and answered questions about tinnitus. Results: We estimated the prevalence of any spontaneous tinnitus as 28.1% (95% CI 27.1, 29.2%), and the prevalence of ‘clinically significant’ tinnitus as 3.1% (95% CI 2.7, 3.5%). Children were less likely to have clinically significant tinnitus if the tinnitus was ‘soft’ rather than ‘loud’ and if continuous rather than intermittent. Clinical significance was more likely if the tinnitus occurred more than once a week. Neither pitch nor length of history were important determinants of clinical significance. Small increases in mean hearing threshold (of up to 2.3 dB HL) were associated with clinically significant tinnitus. Conclusions: Although the prevalence of any tinnitus in 11-year-old children appears high, the small proportion in which this was found to be clinically significant implies that this does not necessarily indicate a large unmet clinical demand. We would expect approximately one child per class of 30 to have clinically significant tinnitus which is, by definition, problematic

A systematic review of job demands and resources associated with compassion fatigue in mental health professionals

Psychosocial hazards in mental healthcare contribute to the development of compassion fatigue in mental health professionals. Compassion fatigue has a negative impact on the mental health and wellbeing of professionals that can impair the quality of services provided to clients. The majority of research on compassion fatigue has focused on individual-level variables such as gender, history of trauma and age, among others. It is also imperative to understand the role played by alterable work-related characteristics in contributing to the development of compassion fatigue in order to attenuate its impact on mental health professionals and their clients. The present review examined articles exploring work-related factors associated with compassion fatigue. Fifteen quantitative studies were included and their quality was assessed using a checklist. An inductive content-analysis approach was adopted to synthesise the themes emerging from the data. The results suggested a theoretical model consistent with the Job Demands-Resources model, wherein job demands (such as workplace trauma, workload and therapeutic settings) are associated with compassion fatigue, and job resources (such as supervisors’, coworkers’ and organisational support) mitigate the impact of job demands. In addition to person-oriented factors, work-related factors are critical for the prevention of compassion fatigue

Investigating the assessment practices within an Initial Teacher Education program in an Australian university: Staff perceptions and practices

Effective assessment design and subsequent assessment practices are essential for student success in the higher education sector. A plethora of research on assessment in higher education exists which tends to focus primarily on the student experience. This paper shares results from a 3 phased study that explored staff perceptions related to assessment practices in an undergraduate Initial Teacher Education program within an Australian metropolitan university. First, course learning objectives, activities and assessment items were mapped to identify the presence of constructive alignment. Second, staff were invited to complete a survey and a follow-up interview in relation to understanding of assessment knowledge and skills. Fink’s Taxonomy of Significant Learning (2013) was used to analyse the qualitative data and findings suggest that staff are highly committed to quality assessment practices but often work in silos rather than teams. Additionally, a lack of professional development and learning was available at the school level, particularly for casual staff. Further research about assessment practices in higher education in relation to staff rather than student experience is warranted

Cancer survivors treated with platinum-based chemotherapy affected by ototoxicity and the impact on quality of life: a narrative synthesis systematic review

© 2019, © 2019 British Society of Audiology, International Society of Audiology, and Nordic Audiological Society. Objective: To identify any change in quality of life (QoL) caused by chemotherapy-induced toxicities, such as hearing loss and tinnitus, to provide information in order to improve services and aid clinicians in their decision-making. Design: This systematic review followed the preferred reporting items for systematic reviews and meta-analysis (PRISMA) checklist. The search terms were cancer, platinum-based chemotherapy, ototoxicity and “quality of life”. Titles and abstracts, followed by full texts, were screened by two independent researchers. The relevant data were extracted and quality analysis was performed using the NIH Quality Assessment Tool. Study sample: About 308 titles and abstracts were screened, and 27 full-text articles were screened. Ten articles representing 11 studies were included in the review. Study design included cross-sectional studies, randomised control trials and longitudinal studies. Results: Diagnostic criteria consisted of audiograms, questionnaires and patient complaints. The study quality ranged from 21.43% to 85.71%. Overall results found that those treated with cisplatin had more hearing loss and tinnitus than those treated with other therapies. Furthermore, those with hearing loss and tinnitus were more likely to have a lower QoL. Conclusions: There is an urgent need to standardise diagnostics when investigating ototoxicity and its effect on QoL, particularly for research into risk factors, prevention and management
