Investigating the Use of Choking Intervention Strategies With Choking-Susceptible Athletes
… definitions (e.g., Hall, 2004; Wang 2002), choking is defined as a critical deterioration in the execution of habitual processes as a result of an elevation in anxiety levels under perceived pressure. The self-focus model of choking (Baumeister, 1984; Beilock & Carr, 2001; Masters, 1992), …

The Big Five Personality Traits and Choking Susceptibility
Choking susceptibility is the likelihood or potential of an individual choking under pressure (Mesagno et al., 2012). Choking susceptibility may be influenced by personality traits. The purpose of this study was to examine the differences between the Big Five personality traits on choking …

Developing and Testing an Integrated Model of Choking in Sport
In general, choking has been defined as the occurrence of sub-optimal performance under pressure (Baumeister and Showers, 1986). The most widely accepted theory of choking is what I have labeled the 'automatic execution model' (Baumeister, 1984), the basic premise being that choking occurs due to …

Choking under pressure : attention and motor control in performance situations
… of conditions (e.g. an audience) that elicit choking and that moderate (e.g. trait-anxiety) pressure – performance relation. Furthermore, mediating processes have been investigated. For example, explicit monitoring theories link performance failure under psychological stress to an increase in …

Mass spectrometric methods for analyses of blister and choking agent markers
Identification of the alleged use of toxic chemicals in chemical weapons is demanding. The lack of verification methods for analysing nitrogen mustards and chlorine in biomedical and environmental samples prompted the development of methods for the preparedness of the Organisation for the …

The role of dispositional reinvestment in choking during decision-making tasks in sport
… effect of dispositional reinvestment upon ‘choking’ in cognitive based tasks such as decision-making. Study 1 tested sixty-three participants’ performances on low- and high-complexity tests of motor skill, psychomotor skill and working memory under low- and high-pressure conditions. The …

Numerical Examination of Flow Field Characteristics and Fabri Choking of 2D Supersonic Ejectors
An automated computer simulation of the two-dimensional planar Cal Poly Supersonic Ejector test rig is developed. The purpose of the simulation is to identify the operating conditions which produce the saturated, Fabri choke and Fabri block aerodynamic flow patterns. The effect of primary to …

Uncovering the Psychological and Physiological Factors that Influence Performance and Choking Under Pressure
… 2010; Mesagno et al., 2015). Although the main choking under pressure theories have been researched independently for decades, both Hill et al. (2010) and Lewis and Linder (1997) suggested that these theories are no longer mutually exclusive, with the potential to converge providing insight into …

Choking on the madeleine: encounters and alternative approaches to memory in a contemporary art practice
This practice-based thesis proposes radical, critical, creative reconsiderations of memory and how the mnemic may be expressed in art practice. The research took place through developing a series of works within contemporary installation art practice, which considers the experience of memory an …

Threats to success in mathematics: examining the combined effects of choking under pressure and stereotype threat
Girls and boys do not choose to go into mathematics dependent careers at the same rate. Understanding this gap is more complicated than simply looking at performance differences between boys and girls. This disparity in career choice could stem from differences in motivation that can be seen as …

Exploring the attentional processes of expert performers and the impact of priming on motor skill execution
… decrements. This phenomenon has been termed ‘choking under pressure’ and has been the subject of extensive research in sport psychology. Despite this attention, gaps in the literature remain leaving opportunities for further advancements in knowledge about the phenomenon, particularly in …

The Formation, Propagation and Stability of Self-Sustained Detonation Waves in Gaseous Mixtures, Condensed-Phase Explosives and Media With Hydraulic Resistance
… versus friction curves for super-detonation, choking detonation, and shockless subsonic detonation. Numerical investigation of stability of subsonic detonation shows that an increase of hydraulic resistance destibilizes the detonation, wherease an increase of the chain-branching temperature …

Experimental evaluation and modeling of a turbine blade with potassium evaporative cooling
… gas turbine engine. These limits include vapor choking in the internal blade passages, pool boiling limits in the blade, and surface tension restriction of liquid flow. Experimental results are presented from testing in the Rotating Heat Transfer Rig at the Massachusetts Institute of Technology. …

Analysis of bandwidth attacks in a bittorrent swarm
… BitTorrent is an incentive mechanism, called a choking algorithm, which rewards peers that share. Currently, BitTorrent is one of the most widely used protocols on the Internet. Therefore, it is important to investigate the security of this protocol. While significant progress has been made in …

A combined cycle approach to dual-mode scramjet design and analysis
… the primary source of loss of performance. Flow choking studies were performed in both axisymmetric and rectangular scramjet flowpaths, revealing notable differences in the shock train structure and the dynamics of the advancing pseudoshock during mode transition and choking phases. Lastly, the …
