EEG-based neurophysiological indices for expert psychomotor performance – a review

A primary objective of current human neuropsychological performance research is to define the physiological correlates of adaptive knowledge utilization, in order to support the enhanced execution of both simple and complex tasks. Within the present article, electroencephalography-based neurophysiological indices characterizing expert psychomotor performance, will be explored. As a means of characterizing fundamental processes underlying efficient psychometric performance, the neural efficiency model will be evaluated in terms of alpha-wave-based selective cortical processes. Cognitive and motor domains will initially be explored independently, which will act to encapsulate the task-related neuronal adaptive requirements for enhanced psychomotor performance associating with the neural efficiency model. Moderating variables impacting the practical application of such neuropsychological model, will also be investigated. As a result, the aim of this review is to provide insight into detectable task-related modulation involved in developed neurocognitive strategies which support heightened psychomotor performance, for the implementation within practical settings requiring a high degree of expert performance (such as sports or military operational settings)

'Pushing through the pain cave': Lived experiences of pain tolerance in male ultra-marathon runners

Extant research has typically focused on the study of pain tolerance in endurance sport from a psychophysiological perspective, with findings illustrating that ultra-runners can tolerate pain for a longer duration of time than non-running active controls. However, qualitative investigation that explores the lived experiences of pain tolerance in ultra-running has been limited thus far. This research explored the lived experiences of pain tolerance in male ultra-marathon runners and how this evolved over time. Six male ultra-marathon runners were interviewed using a semi-structured interview guide. The methodology and analysis were guided by Interpretative Phenomenological Analysis. Four group experiential themes (GETs) were identified, and these are: building relationships with pain, what is ‘real’ pain? gratification of pushing through pain, and the trajectory of enduring hardship. The findings highlight the challenge of distinguishing between discomfort and real pain and the influence of socio-cultural norms on pain tolerance within ultra-running. The study raises important applied implications for coaches and sport psychology practitioners with regards to developing a holistic picture of ultra-runners’ pain experiences and cultivating environments that facilitate multiple narratives and enhance individuals ultra-running experiences

God and Astrobiology

The perception that life on other planets would be, problematic for religious people, and indeed for religion itself, is a longstanding one. It is partially rooted in fact: astrobiological speculations have, on occasion, engendered religious controversies. Historical discussions are often far more nuanced, and less one-sided than often imagined. 'Exotheology' is a lively subdiscipline within several religious traditions. This Element offers a wide-ranging introduction to the multifarious 'problems of God and astrobiology', real and perceived. It covers major topics within Christian theology (e.g., creation, incarnation, salvation), as well as issues specific to Judaism, Islam, Buddhism, and Hinduism. It also discusses the very different perspectives offered by other (non)religious traditions, including Mormonism, various 'alien-positive' new religious movements (e.g., Heaven's Gate, Scientology, Raëlism), and the 'Ancient Astronaunt' theories popularized by Erich von Dāniken and the History channel's Ancient Aliens

‘Assisted dying’ as a comforting heteronomy: the rejection of self-administration in the purported act of self-determination

‘Assisted dying’ (an umbrella term for euthanasia and/or assisted suicide) is frequently defended as an act of autonomous self-determination in death but, given a choice, between 93.3% and 100% of patients are reluctant to self-administer (median 99.5%). If required to self-administer, fewer patients request assisted death and, of these, a sizable proportion do not self-administer but die of natural causes. This manifest avoidance runs counter to the concept of autonomous self-determination, even on the supposition that suicide could truly be autonomous. The avoidance of self-administration does not show that self-administration, when it occurs, is necessarily autonomous. It suggests, rather, that there are other frames by which assisted dying is being understood. One such is desire for medical control, a desire shared by patients and doctors. Such a frame is not directed towards an exacting autonomy (self-directed action by the patient) but towards a comforting heteronomy (letting the doctor take control)

Examining the importance of local and global patterns for familiarity detection in soccer action sequences

Pattern recognition is a defining characteristic of expertise across multiple domains. Given the dynamic interactions at local and global levels, team sports can provide a vehicle for investigating skilled pattern recognition. The aims of this study were to investigate whether global patterns could be recognised on the basis of localised relational information and if relations between certain display features were more important than others for successful pattern recognition. Elite (n = 20), skilled (n = 34), and less-skilled (n = 37) soccer players completed three recognition paradigms of stimuli presented in point-light-stimuli format across three counterbalanced conditions: ‘whole-part’; ‘part-whole’; and ‘whole-whole’. ‘Whole’ clips represented a 11v11 soccer match and ‘part’ clips presented the same passages of play with only two centre forwards or two peripheral players. Elite players recognised significantly more accurately than the skilled and less-skilled groups. Participants were significantly more accurate in the ‘whole-whole’ condition compared to others, and recognised stimuli featuring the two central attacking players significantly more accurately than those featuring peripheral players. Findings provide evidence that elite players can encode localised relations and then extrapolate this information to recognise more global macro patterns

Integrating strength and conditioning training and golf practice during the golf season: approaches and perceptions of highly skilled golfers

Contemporary evidence has demonstrated strength and conditioning (S&C) training benefits golf performance, primarily through improving clubhead speed. However, no empirical data exist that describe how, or even if, golfers integrate their S&C training and golf practice. Therefore, the aim of this study was to investigate the perceptions and practices of skilled golfers with regards planning the season and how S&C is structured in the golf year. Sixty-five (male n= 48. Female n= 17) category 1 amateur (n= 50) and professional (n= 15) golfers completed a mixed-methods online survey. Survey answers were either golf practice or S&C training focused. Results showed the majority of golfers engage with S&C training (n= 44; 67.7 %) and follow a programme (n= 53. 81.5 %). Contrastingly, they reported having little structure for golf practice, choosing to have no annual plan (n= 14; 21.9 %), have a reactive approach (n= 22. 34.9 %) based on recent performances, or train what feels appropriate/enjoyable (n= 15; 23.8 %). Golfers reported they adjust their training around competition (n= 47; 74.6 %), but with various approaches. The dichotomous and contradictory responses received across multiple answers demonstrate continued education and research is required to help golfers integrate S&C training with their golf practice

Using participative techniques to mediate power relationships between the researcher and child participant

Purpose: This study explores how power dynamics affect research with children, focusing on how the projected and perceived role of the researcher and the use of participative techniques, can mediate power relationships between the researcher and child, and impact children’s agency. Methodology: The research formed part of a wider study on children’s digital device use, with children aged 4 to 11 in a UK school. Eight pairs of children participated in buddy interviews, completing several creative and arts-based activities using a choice of equipment and materials, including PlayDoh, LEGO and, most innovatively, Minecraft. Findings: The study found the researcher’s projected role, and children’s interpretation of this, impacted the power relations in the interviews. A consistent projection was challenging however, and it was necessary for the researcher to adapt their role according to children’s needs and behaviour. Offering children a choice of activities was an effective power sharing strategy, and children’s absorption in these tasks provided a wealth of data from observations and children’s on-task ‘chatter’. Originality: Using Minecraft as a participative method enabled the children to use their superior technical abilities to take power in the interview, and show their own personal geographies virtually in 3D, and offers potential for other qualitative researchers in conducting research with the agentic child

Intra‐ and interindividual reliability of muscle pain induced by an intramuscular injection of hypertonic saline injection into the quadriceps

Background: Intramuscular injections of hypertonic saline are commonly used to induce experimental muscle pain, but reliability data on this technique are lacking. This study investigated the intra‐ and interindividual reliability of pain measures from a hypertonic saline injection into the vastus lateralis. Methods: Fourteen healthy participants (6 female) attended three laboratory visits where they received an intramuscular injection of 1 mL hypertonic saline into the vastus lateralis. Changes in pain intensity were recorded on an electronic visual analogue scale, and pain quality was assessed after pain had resolved. Reliability was assessed with the coefficient of variation (CV), minimum detectable change (MDC) and intraclass correlation coefficient (ICC) with 95% CIs. Results: Mean pain intensity displayed high levels of intraindividual variability (CV = 16.3 [10.5–22.0]%) and ‘poor’ to ‘very good’ relative reliability (ICC = 0.71 [0.45–0.88]) but had a MDC of 11 [8–16] au (out of 100). Peak pain intensity exhibited high levels of intraindividual variability (CV = 14.8 [8.8–20.8]%) with ‘moderate’ to ‘excellent’ levels of relative reliability (ICC = 0.81 [0.62–0.92]), whereas the MDC was 18 [14–26] au. Measures of pain quality exhibited good reliability. Interindividual variability in pain measures was high (CV > 37%). Conclusions: Intramuscular injections of 1 mL of hypertonic saline into the vastus lateralis display substantial levels of interindividual variability, but MDC is below the clinically important changes in pain. This model of experimental pain is suitable for studies involving repeated exposures. Significance: Many pain research studies have performed intramuscular injections of hypertonic saline to investigate responses to muscle pain. However, the reliability of this technique is not well established. We examined the pain response over three repeated sessions of a hypertonic saline injection. The pain induced by hypertonic saline has considerable interindividual variability but has largely acceptable intraindividual reliability. Therefore, the injections of hypertonic saline to induce muscle pain are a reliable model of experimental muscle pain
