An Integrative Model of Situation Awareness

Thurston, Andrew 16 May 2016 (has links)
In aviation safety incident reports, lack of situation awareness (SA) is often attributed as the cause of negative safety outcomes, such as accidents. While the predominant model of SA has identified three components of SA, perception, comprehension, and projection, assumptions of their relationships with each other and external criteria are yet tested empirically. Specifically, SA theory suggests comprehension SA fully mediates the relationship between perception and projection SA. Additionally, research on the relationships between individual differences and SA is lacking. The purpose of the current study is to test a comprehensive model of SA which simultaneously examines the described mediation, relationships with individual differences antecedents of SA, and its utility as a predictor of safety using structural equation modeling (SEM). A sample of 349 employees from a diverse background of occupational areas were recruited via Amazon Mechanical Turk to test the model. While self-report measurement of SA was an excellent predictor of safety, the current study did not find empirical support for the presumed mediation among the SA components, and found the relationships between individual differences and SA which contradict extant SA theory. The results suggest differentiating between typical versus maximal SA. Implications for theory and practice are discussed.

Samband mellan kognitiva faktorer och förmågan att korrekt identifiera ansikten

Härdevik, Hanna, Blusi, Lisa January 2021 (has links)
Vittnesmål spelar en avgörande roll som bevisning vid brottmål och att vittna utgör en viktig del i att kunna klara upp brott. Att ögonvittnen identifierar en person är en vanlig metod för att få bevismaterial i en rättegång eller för att vägleda polisen i utrednings- och spaningssammanhang. Ögonvittnesidentifiering av ansikten är dock inte en helt säker metod då det mänskliga minnet besitter begränsningar och är sårbart för suggestioner vilket gör det nödvändigt att undersöka samband mellan kognitiva faktorer och förmågan att korrekt identifiera ansikten. Detta i syfte att minska antalet felaktiga identifikationer av oskyldiga. Syftet med studien var att besvara frågan om förmågan till ansiktsigenkänning kan prediceras av kognitiva förmågor. Studien har nyttjat insamlad data från den longitudinella studien Betula(Nilsson m.fl., 1997) som startade 1988 i Umeå. Med ett urval om 1 715 personer i åldrarna35–85 år (M = 58.22, SD = 13.79) har resultatet från nio olika kognitiva tester utforskats i förhållande till ett ansiktsigenkänningstest bestående av barnansikten. Genom korrelationsanalyser och stegvisa regressionsanalyser framkom att förmågan till ansiktsigenkänningsförmåga kan prediceras till viss del. Den starkaste prediktorn för ansiktsigenkänning var visuospatial förmåga och flytande intelligens. Förmågan att känna igen ansikten verkar inte försämras vid högre ålder, vilket gäller för andra kognitiva förmågor. / Testimony plays a crucial role in the work of presenting evidence in criminal cases and to solve crimes. Eyewitness to identification is commonly used method to collect evidence for a trial or to aid the police in their investigations. However, identification of faces is not a completely reliable method because the human memory has limitations and is vulnerable to suggestions, which stresses the importance of investigating relationships between cognitive factors and the ability to correctly identify faces. This in order to reduce the number of incorrect identifications of innocent people. Thus, the purpose of this study was to answer the question “whether theability to recognize faces can be predicted by cognitive abilities”. This study has made use of data collected within the longitudinal Betula study (Nilsson et al, 1997) which started in Umeå in 1988. With a sample of 1 715 participants in aged 35-85 years (M = 58.22, SD = 13.79)results from nine different cognitive tests were explored in relation to performance in facerecognition task consisting of children’s faces. Through correlation analyzes and stepwiseregression analyzes, it emerged that the ability to face recognition ability can be predicted tosome extent. The strongest predictor of facial recognition was visuospatial ability and fluid intelligence. The ability to recognize faces does not seem to deteriorate at an older age, required for other cognitive abilities.

Investigating Cyber Performance: An Individual Differences Study

Kelly Anne Cole (10907916) 04 August 2021 (has links)
<div>The persistent issues that have been identified in the cyber defense domain, such as information-overload, burn-out and high turn-over rates among cyber analysts leads us to question what the cognitive ability contribution is to a more successful cyber performance. Cyber defense researchers theorize that individual differences are determinants of cyber performance success but have yet to establish empirically the role of individual differences. Therefore, the study uses an individual differences approach under a work performance framework to study the contributions of cognitive ability (i.e., attention control) on cyber performance success in a specific cyber work-role (i.e., the Incident Reponder), and through its well-defined primary task (i.e., incident detection system performance). The sample included actual network analysts with a wide range of incident detection expertise, age, and education levels for more reliable and valid scores. The results of the correlational analysis showed that individual differences in attention control (i.e., flexibility and spatial attention) contribute most to the differences in Incident Responder work-performance. A linear regression model then demonstrated that spatial attention and flexibility predict 53 to 60 percent of the variance in cyber performance scores. It is suggested that the KSA's from the NICE framework be updated with the cognitive abilities that contribute to and/or predict cyber performance success, for superior recruitment efforts towards a more efficient cyber defense work-force. </div><div><br></div>

Children's ability to navigate through a streaming services such as TV4 Play / Barns förmåga att navigera genom en streamingtjänst som TV4 Play

Roman, Kristina January 2015 (has links)
Due to the increased use of Internet among children, developers have realized that digital environments need better usability, especially to give children the opportunity to handle digital interfaces on their own. This paper investigates how children handle and navigate the online streaming service TV4 Play. The aim of this study was to understand the children’s moves and actions for further development of a more child-centered site that should make it easier for them to handle. The study was based upon a Usability Evaluation Method (UEM) called Peer-Tutoring, where pairs of children cooperated and taught each other, one by one, to solve tasks based on navigation through the interface. This method was also combined with a method called Active Intervention, where questions were added to the Peer-Tutoring in order to invite the children to talk and reflect on their actions. The participants were 4-6 year old children from a preschool in Danderyd, Stockholm. The results show difficulties of navigating and understanding the structure of the site, which is closely related to children’s limited cognitive ability, for instance, adults have superior capacity to handle drag and drop compared to children. These results led to recommendations that the TV4 Play team can take into account when they optimize usability for children. For example, they should implement one-click buttons instead of drag-and-drop functions, and list the available TV shows in a horizontal overview. / På grund av den ökade användningen av Internet bland barn, har utvecklarna insett att digitala miljöer behöver bättre användbarhet, särskilt för att ge barnen möjlighet att hantera digitala gränssnitt på egen hand. Denna uppsats undersöker hur barn hanterar och navigerar på streaming tjänsten TV4 Play. Syftet med denna studie var att förstå barnens rörelser och åtgärder för vidareutveckling av en mer barncentrerade webbplats, som ska göra det lättare för dem att hantera. Studien baserades på en användbarhets utvärderingsmetod, som kallas Peer-Tutoring, där barnen i par samarbetar och lär varandra, en efter en, för att lösa uppgifter baserade på navigering via gränssnittet. Denna metod kombinerades med en metod som kallas aktivt ingripande (Active Intervention), där frågor ställdes för att bjuda in barnen till att prata och reflektera över sina handlingar. Barnen var 4-6 år gamla från en förskola i Danderyd, Stockholm. Resultaten visar svårigheterna att navigera och förstå strukturen på webbplatsen, vilket är nära relaterat till barnens begränsade kognitiva förmåga, t ex har vuxna överlägsen kapacitet att hantera dra-och-släpp jämfört med barn. Dessa resultat har lett till rekommendationer som TV4 Play teamet kan ta hänsyn till när de optimerar användbarheten för barn. Till exempel bör de implementera klickknappar istället för dra-och-släpp-funktioner och lista tillgängliga TV-program i en horisontell översikt.

Thinking Perspective Profiles as a Predictor of Intelligence Analysts' Job Performance.

Rasmussen, Curtis 01 January 2018 (has links)
Empirical research has supported the use of general cognitive ability to predict employee performance; however, studies have accounted for only a fraction of the variance. The current study addressed whether intellectual styles, which describe how individuals habitually acquire and use information, account for a significant portion of the variance in job performance not covered by general cognitive ability. The study followed a quantitative, nonexperimental design with a convenience sample of 77 intelligence analysts from 6 U.S. government agencies and 2 online professional groups. MindTime provided the primary theoretical framework. The International Cognitive Ability Resource, MindTime Profile InventoryTM, and Self-Rated Analytic Job Performance Assessment were used to measure general cognitive ability and analytic job performance. Results of multiple linear regression analysis indicated that thinking perspectives profiles are valid predictors of job performance and contribute to the incremental validity of general cognitive ability as a predictor of analytic job performance. However, because of the high degree of collinearity, results were inconclusive. The findings add to the understanding of the relationship between intellectual styles and job performance of knowledge workers, and they reinforce links between industrial-organizational psychology and cognitive psychology.

Cognitive Complexity, Perspective Taking, and Moral Reasoning in Depression

Jackson, Daniel Wayne 08 1900 (has links)
The relationships of cognitive complexity, social perspective taking, and moral reasoning have been primarily examined in children or juveniles. Little work has been done to study their relationships in the late adolescent and young adult college student population. Additionally, the research to date has only examined relationships among pairs of these constructs. There has been no attempt to assess the combined relationship of cognitive complexity and role-taking skills to moral reasoning at any developmental level. Therefore, there are two purposes in this study. First, to test the theory of ego function regression in depression on cognitive developmental concepts related to interpersonal functioning. Second, the study will determine the individual as well as combined relationships of cognitive complexity and social perspective taking to moral judgment in a late adolescent to young adult college student population.

The relationship between cognitive ability, emotional intelligence and negative career thoughts : a study of career-exploring adults

Dahl, Arthur Dennis 06 1900 (has links)
Career exploration and decision making can be a stressful experience, and is often accompanied by dysfunctional thinking regarding the world of work and one’s place in it. Individuals who are able to modify their negative career thoughts are more likely to navigate career exploration successfully. Factors which may influence a person’s ability to cope with dysfunctional thoughts include cognitive ability (IQ) and the inadequately explored construct of emotional intelligence (EI). Establishing the validity of EI by demonstrating its relationship to important outcomes is necessary. This study sought to determine the extent to which IQ and EI were associated with negative career thoughts and negative career thoughts change as a result of career exploration. This correlational study measured IQ using a standard measure and EI using an ability-based instrument. In addition, negative career thoughts were measured both before and after a career exploration program. One hundred ninety three unemployed adults between the ages of 25 and 60 participated in the study. Significant correlation relationships were found between IQ and aspects of negative career thoughts post program. Only one branch of the EI model, managing emotions, was seen to correlate significantly with all aspects of negative career thoughts, both before and after career exploration. No correlations were found between either IQ or EI with negative career thoughts change. Regression analysis indicated that IQ predicted overall negative career thoughts as well as decision-making confusion, but only after career exploration. Overall EI scores did not predict negative career thoughts. However, among the four branches of EI, managing emotions predicted negative career thoughts both before and after career exploration for all of global negative career thoughts, decision-making confusion, commitment anxiety, and external conflict. Neither IQ nor EI predicted negative career thoughts change. The results show that the ability to manage emotions is associated with reduced dysfunctional thinking both before and after career exploration, suggesting that EI managing may be a psychological resource that individuals use in coping with stress. / Industrial and Organisational Psychology / D.Litt. et Phil.
