    We explored the cognitive and affective components of the Theory of Challenge and Threat States in Athletes (TCTSA) using a cross-sectional design. One hundred and seventy-seven collegiate athletes indicated how they typically approached an important competition on measures of self-efficacy, perceived control, achievement goals, emotional states and interpretation of emotional states. Participants also indicated to what extent they typically perceived the important competition as a challenge and/or a threat. The results suggest that a perception of challenge was not predicted by any of the cognitive components. A perception of threat was positively predicted by avoidance goals and negatively predicted by self-efficacy and approach goals. Both challenge and threat had a positive relationship with anxiety. Practical implications of this study are that an avoidance orientation appeared to be related to potentially negative constructs such as anxiety, threat and dejection. The findings may suggest that practitioners and researchers should focus on reducing an avoidance orientation, however the results should be treated with caution in applied settings, as this study did not examine how the combination of constructs exactly influences sport performance. The results provided partial support for the TCTSA with stronger support for proposed relationships with threat rather than challenge states

    Objective: The aim of this study was to identify the cognitive components required for offshore drillers to develop and maintain situation awareness (SA) while controlling subsea hydrocarbon wells. Background: SA issues are often identified as contributing factors to drilling incidents, most recently in the Deepwater Horizon blowout. Yet, there is a limited body of research investigating SA in the offshore drilling environment. Method: In the first study, critical incident interviews were conducted with 18 experienced drilling personnel. Transcripts were subjected to theory driven thematic analysis, producing a preliminary cognitive framework of how drillers develop and maintain SA during well control. In the second study, 24 hr of observations (in vivo and video) of drillers managing a high fidelity well-control simulator were analyzed to further develop the framework. Results: The cognitive components that enable drillers to build up an understanding of what is happening in the wellbore and surrounding environment, to predict how this understanding may develop, were identified. These components included cue recognition, interpretation of information in conjunction with the current mental model, and projection through mental simulation. Factors such as distracters, expectations, and information sharing between crew members can both positively and negatively influence the drillers SA. Conclusion: The findings give a preliminary understanding into the components of drillers SA, highlighting the importance of SA for safe and effective performance and indicating that Endsleys model of SA can be applied to drilling. Application: The results have consequences for training, task management, and work design recommendations

    Situation Awareness (SA) issues are often identified as contributing factors to drilling incidents, most recently in the Deepwater Horizon blowout. Two studies aimed to identify the cognitive components required for offshore drillers to develop and maintain SA whilst controlling subsea hydrocarbon wells. In study one, critical incident interviews were conducted with 18 experienced drilling personnel. Transcripts were subjected to thematic analysis, producing a framework of cognitive processes that enable drillers to build up an understanding of what is happening in the well bore and surrounding environment, predicting how the situation may develop. In the second study, analysis of 24 hours of observations (in-vivo and video) from a high fidelity well control simulator suggest behaviors such as monitoring and crew sharing information contribute to the drillers' SA. The findings highlight the importance of SA for safe and effective performance in drilling and are being used to develop a cognitive task analysis

    Cognitive and personality components underlying spoken idiom comprehension in context. An exploratory study.

    In this exploratory study, we investigated whether and to what extent individual differences in cognitive and personality variables are associated with spoken idiom comprehension in context. Language unimpaired participants were enrolled in a cross-modal lexical decision study in which semantically ambiguous Italian idioms (i.e., strings with both a literal and an idiomatic interpretation as, for instance, break the ice), predictable or unpredictable before the string offset, were embedded in idiom-biasing contexts. To explore the contributions of different cognitive and personality components, participants also completed a series of tests respectively assessing general speed, inhibitory control, short-term and working memory, cognitive flexibility, crystallized and fluid intelligence, and personality. Stepwise regression analyses revealed that online idiom comprehension was associated with the participants\u2019 working memory, inhibitory control and crystallized verbal intelligence, an association modulated by idiom type. Also personality-related variables (State Anxiety and Openness to Experience) were associated with idiom comprehension, although in marginally significant ways. These results contribute to the renewed interest on how individual variability modulates language comprehension, and for the first time document contributions of individual variability on lexicalized, high frequency multi-word expressions as idioms adding new knowledge to the existing evidence on metaphor and sarcasm

    Biased Attentional Processing for Negative Emotion and Youth Internalizing Psychopathology: The Role of Attentional Control Deficits

    Get PDF
    Biased attention for salient negative emotional stimuli is a proposed cognitive mechanism of internalizing disorders, namely depression and anxiety. Previous studies have demonstrated biases in bottom-up, stimulus-driven attentional systems, as well as top-down, goal-oriented attentional systems, in the context of negative emotion. However, the underlying cognitive mechanisms that drive these biases, such as attentional control deficits, are not well understood. Furthermore, given the high degree of conceptual and empirical overlap between depression and anxiety, it is unclear how biased attention might relate to constructs common across both disorders, such as general distress, versus what is specific to each disorder. The current study utilized an emotional adaptation of the Antisaccade Task with eye-tracking to precisely and accurately tease apart components of attentional control, including inhibition and shifting, in the context of social threat (i.e., anger) in a community sample of youth and young adults (ages 13-22; N = 80). Findings show that difficulty inhibiting attention for social threat is associated with symptoms of general distress, which are shared across depression and anxiety, as well as symptoms of physiological hyperarousal that are specific to anxiety. Overall, findings further clarify what specific components of attentional control deficits underlie biased attentional processing, a well-established cognitive mechanism of internalizing disorders

    Function-Theoretic Explanation and the Search for Neural Mechanisms

    Get PDF
    A common kind of explanation in cognitive neuroscience might be called functiontheoretic: with some target cognitive capacity in view, the theorist hypothesizes that the system computes a well-defined function (in the mathematical sense) and explains how computing this function constitutes (in the system’s normal environment) the exercise of the cognitive capacity. Recently, proponents of the so-called ‘new mechanist’ approach in philosophy of science have argued that a model of a cognitive capacity is explanatory only to the extent that it reveals the causal structure of the mechanism underlying the capacity. If they are right, then a cognitive model that resists a transparent mapping to known neural mechanisms fails to be explanatory. I argue that a functiontheoretic characterization of a cognitive capacity can be genuinely explanatory even absent an account of how the capacity is realized in neural hardware

    Perception of soundscapes : an interdisciplinary approach

    Get PDF
    This paper takes an overall view of findings from the Positive Soundscape Project, a large inter-disciplinary soundscapes study. Qualitative fieldwork (soundwalks and focus groups) have found that soundscape perception is influenced by cognitive effects such as the meaning of a soundscape and its components, and how information is conveyed by a soundscape, for example on the behaviour of people within the soundscape. Three significant clusters were found in the language people use to describe soundscapes: sound sources, sound descriptors and soundscape descriptors. Results from listening tests and soundwalks have been integrated to show that the two principal dimensions of soundscape emotional response seem to be calmness and vibrancy. Further, vibrancy seems to have two aspects: organisation of sounds and changes over time. The possible application of the results to soundscape assessment and design are briefly discussed

    The organisation of sociality: a manifesto for a new science of multi-agent systems

    No full text
    In this paper, we pose and motivate a challenge, namely the need for a new science of multi-agent systems. We propose that this new science should be grounded, theoretically on a richer conception of sociality, and methodologically on the extensive use of computational modelling for real-world applications and social simulations. Here, the steps we set forth towards meeting that challenge are mainly theoretical. In this respect, we provide a new model of multi-agent systems that reflects a fully explicated conception of cognition, both at the individual and the collective level. Finally, the mechanisms and principles underpinning the model will be examined with particular emphasis on the contributions provided by contemporary organisation theory
