Mapping Between Cognitive Theories And Psycho-Physiological Models Of Attention System Performance, Oliver A. Guidetti, Craig P. Speelman, Peter Bouhlas

Research outputs 2022 to 2026

Declines in the capacity to sustain attention to repetitive, monotonous tasks is a phenomenon known as vigilance decrement (Endsley M, Kiris E. The out-of-the-loop performance problem and level of control in automation. 1995. Hum Factors. 37:32-64). This review compares cognitive theories with psycho-physiological models of vigilance decrement, and a gap is identified in mapping between the 2. That is, theories of vigilance decrement refer to "cognitive" resources; by contrast, psychophysiological models of the cerebral systems associated with attention explain performance functions according to neurochemical resources. A map does not currently exist in the literature that bridges the gap between cognitive …

Calear, Philip J. Batterham, Michelle Torok, Lauren Mcgillivray, Demee Rheinberger, Stephanie Zeritis, Tuguy Esgin, Fiona Shand

Research outputs 2022 to 2026

The risk of suicidal behaviour in Australia varies by age, sex, sexual preference and Indigenous status. Suicide stigma is known to affect suicide rates and help-seeking for suicidal crises. The aim of this study was to investigate the sociodemographic correlates of suicide stigma to assist in prevention efforts. We surveyed community members and individuals who had attended specific emergency departments for suicidal crisis. The respondents were part of a large-scale suicide prevention trial in New South Wales, Australia. The data collected included demographic characteristics, measures of help-seeking and suicide stigma. The linear regression analyses conducted sought to identify the factors …

Alexithymia And Impulsivity In Combat Sports – A Tale Of Three Measures, Craig A. Harms, Oliver R. Barley

Research outputs 2022 to 2026

The purpose of this study was to compare the psychometric properties of two measures of alexithymia – the Toronto Alexithymia Scale (TAS-20) and the Perth Alexithymia Questionnaire (PAQ) – as well as the Barratt Impulsiveness Scale 11 measure of behavioural impulsivity because the psychometric properties of these scales have not been established in athletes. As part of a larger study, 298 participants completed an online survey that included the TAS-20, PAQ, and BIS 11, as well personal- (age and gender) and sport-specific (primary combat sport and level of competition) demographic measures. A unidimensional model was retained for the TAS-20. A …

Editorial: Sleep, Vigilance & Disruptive Behaviors, Osman S. Ipsiroglu, Gerhard Klösch, Rosalia C. Silvestri, Susan M. Mccabe, Georg Dorffner, Thomas C. Wetter, Luci Wiggs

Research outputs 2022 to 2026

The Frontiers in Psychiatry Research Theme of Sleep, vigilance, and disruptive behaviors has two aims: first, to promote the understanding of the connections between vigilance and disruptive daytime behavior in the context of sleep deprivation and, second, to explore how naturalistic observations and pattern recognition can play a role in furthering our understanding of these connections. . . .

Autonomy Versus Support: Self-Reliance And Help-Seeking For Mental Health Problems In Young People, Amelia Ishikawa, Debra Rickwood, Emily Bariola, Navjot Bhullar

Research outputs 2022 to 2026

Purpose:

Many young people with mental ill-health do not seek support, and developmental growth in self-reliance may be a barrier to help-seeking. Increasing autonomy is a positive developmental task for youth and a key aspect of resilience. This study examined the influence of perceived social support and resilience on the previously unexamined relationship between self-reliance and intentions to seek help from informal, professional, and self-help sources for mental health problems.

Methods:

An online survey was completed by a representative Australian community sample of 5,203 young people aged 12–25 years (half female), in May–June 2020.

Results:

Path analysis showed the hypothesised …
