Search task difficulty

Jingjing Liu, Nicholas J. Belkin · 2011

We report findings on how the user's perception of task difficulty changes before and after searching for information to solve tasks. We found that while in one type of task, the dependent task, this did not change, in another, the parallel task, it did. The findings have implications on designing systems that can provide assistance to users with their search and task solving strategies.

Average of task difficulty.

<div><p>This research aimed to objectively evaluate the optimal state of desk work (flow state) through physiological measurements and use the data to support workers’ mental health and well-being. We suppose that the flow state evaluation in real-time can contribute to a concentrated work environment, improved work efficiency, and stabilize worker’s minds. This study reports on the development of the mental task modeled on daily work for the physiological measurement experiment. In the first phase of the research, a field survey was conducted with 55 desk workers to understand the details of their jobs and develop suitable mental tasks. Further, the relationship between daily work content and subjective stress was clarified. In the second phase, based on the results of the field survey, a task inducing the flow state was developed for practical use. Through empirical experiments with 35 participants (22 adults and 13 students), the developed task was evaluated for its usefulness and possible issues by examining the relationships among subjective assessment, task performance, degree of flow state, and individual characteristics. The study results showed that the proposed mental task developed in this study constitutes practical work that can be used for concentrated and goal-directed efforts. The task also demonstrated the property of inducing a flow state. Further, the results suggest that it is necessary to adjust the task difficulty level and implement effective feedback methods to induce the flow state more effectively.</p></div>

Task difficulty in SLA

Janik, Anna · Jagiellonian University Repository (Jagiellonian University)

StreszczenieNiniejsze badanie przedstawia problem trudności zadania, co może bezpośredniooddziaływać na wypowiedź ustną uczniów. Jest to kwestia szczególnie istotna dla nauczycieli.Spowodowane jest to tym, iż wiele zaawansowanych uczniów doświadcza trudności wrealizacji ustnych wypowiedzi, które pojawiają się podczas różnego rodzaju egzaminów.Dlatego też to badanie stara się zidentyfikować czynniki, które są odpowiedzialne za trudnośćzadania. Ponadto badanie to stara się najbardziej typowe zadania pogrupować odnajłatwiejszych do najtrudniejszych. Dodatkowo część teoretyczna skupia się na użyciuróżnego rodzaju zadań podczas nauczania i uczenia języka obcego. Z tej przyczyny w częścipraktycznej zademonstrowano cechy, jakie powinny zadania spełniać wspólnie z ich użyciempodczas przyswajania języka obcego. Co więcej badanie to zajmuje się również oceną językamówionego i prezentuje ono różnego rodzaju skale oceniania. Następnie uwaga jest skupionana analizie języka uczniów, która może zostać przeprowadzona przy użyciu miar poprawnościjęzykowej, płynności wypowiedzi i złożoności wypowiedzi.Praktyczna część pracy koncentruje się na ocenie trzech typów zadań: opisu obrazka,układaniu historii na podstawie obrazków i wyrażaniu opinii na dany temat pod względemtrudności. Zebrane informacje zostały zanalizowane biorąc pod uwagę miary poprawnościjęzykowej, płynności wypowiedzi i złożoności wypowiedzi. Oprócz tego uczniowie zostaliocenieni przez uprawnionych egzaminatorów. W ten sposób badanie porównuje miarystatystyczne z oceną wydaną przez człowieka ażeby w ten sposób dostrzec podobieństwa iróżnice pomiędzy nimi.

Task difficulty and recall

Zhang, Ruochong, Madan, Christopher · Open Science Framework · 2021

Our previous experiments examined how varying task load through intervening tasks of different complexity, or pace of presentation, affected memory for visually presented words. In this study, we explore how task load can interact with different recall instructions (i.e., free recall, or recall by any order, vs. serial recall, or recall by item presenting order) to affect recall and recall dynamics.

Does “Task Difficulty” Explain “Task-Induced Deactivation?”

Sam J. Gilbert, Geoffrey Bird, Chris Frith et al. · Frontiers in Psychology · 2012

The "default mode network" is commonly described as a set of brain regions in which activity is suppressed during relatively demanding, or difficult, tasks. But what sort of tasks are these? We review some of the contrasting ways in which a task might be assessed as being difficult, such as error rate, response time, propensity to interfere with performance of other tasks, and requirement for transformation of internal representations versus accumulation of perceptual information. We then describe a fMRI study in which 18 participants performed two "stimulus-oriented" tasks, where responses were directly cued by visual stimuli, alongside a "stimulus-independent" task, with a greater reliance on internally generated information. When indexed by response time and error rate, the stimulus-independent task was intermediate in difficulty between the two stimulus-oriented tasks. Nevertheless, BOLD signal in medial rostral prefrontal cortex (MPFC) - a prominent part of the default mode network - was reduced in the stimulus-independent condition in comparison with both the more difficult and the less difficult stimulus-oriented conditions. By contrast, other regions of the default mode network showed greatest deactivation in the difficult stimulus-oriented condition. There was therefore significant functional heterogeneity between different default mode regions. We conclude that task difficulty - as measured by response time and error rate - does not provide an adequate account of signal change in MPFC. At least in some circumstances, a better predictor of MPFC activity is the requirement of a task for transformation and manipulation of internally represented information, with greatest MPFC activity in situations predominantly requiring attention to perceptual information.

Task difficulty in speaking tests

2016

The difficulty of speaking tasks has only recently become a topic of investigation in language testing. This has been prompted by work on discourse variability in second language acquisition (SLA) research, new classificatory systems for describing tasks, and the advent of statistical techniques that enable the prediction of task difficulty. This article reviews assumptions underlying approaches to research into speaking task difficulty and questionsthe view that test scores always vary with task conditions or discourse variation. A new approach to defining task difficulty in terms of the interaction between pragmatic task features and first language (Ll) cultural background is offered, and the results of a study to investi-gate the impact of these variables on test scores are presented. The relevance for the generalizability of score meaning and the definition of constructs in speaking tests is discussed. I

Attention, task difficulty, and ADHD

Joel T. Nigg · British Journal of Developmental Psychology · 2005

Comments on analysis of attention tasks in Attention Deficit Hyperactivity Disorder (ADHD) provided by Wilding (2005) points out that whereas many regulatory functions, including alertness or arousal, appear to be impaired in ADHD, demonstrating basic attention deficits in selection or orienting functions in the disorder has proven difficult. Yet several issues remain to be addressed in the field with regard to attentional function in ADHD. These include the need for further scrutiny of effects of perceptual load, the psychometric problem of differential task difficulty and differential deficit, relative value of complex versus simple tasks, and consideration of heterogeneity in ADHD. Heterogeneity pertains both to additional analysis of ADHD subtypes, in light of speculation that the Inattentive type may be characterized by true attention problems, and to newer analyses of potential distinct etiological groups within subtype. New analyses of attentional operations have a role to play in these future directions.
