Cognitive task analysis (CTA) is a knowledge elicitation technique employed for acquiring expertise from domain specialists to support the effective instruction of novices. CTA guided instruction has proven effective in improving surgical skills training for medical students and surgical residents. The standard, current method of teaching clinical skills to novices in medical and nursing specialties, including anesthesiology, relies on recall-based instruction from domain experts. This method of instruction is limited by task automation in the expert practitioner. Automated knowledge eludes conscious access and impedes explication of comprehensive essentials for task execution. CTA guided instruction maximizes declarative and procedural knowledge gains in the novice by explicating the necessary equipment, performance objectives, conceptual knowledge, procedural knowledge and performance standards employed when experts execute a particular task. This study employs CTA elicited expertise in the ...
Our results show that task completion times are shorter for interrupted tasks than for tasks with no interruptions when controlled for length-biased sampling. For tasks experiencing one interruption, completion time was almost half that of uninterrupted tasks. Within a clinical setting, there are very few studies of the relationship between interruptions and task completion times, and none have dealt with the problem of length-biased sampling.. Our study is unable to provide an explanation for these results, though several explanations are possible. Most likely is that clinicians, once interrupted, return to the original task but compensate for the time lost in interruption by hastening task completion. This could be done by a faster work rate, reducing the effort spent on task elements, or even dropping task elements. Other possible explanations include that emergency clinicians are refusing interruptions for long or complex tasks, or it may be that shorter tasks are more likely to attract ...

Introduction. Is David Leans adaptation of Hobsons Choice a good performance of the play? Comment on individual performances as well as the production as a whole. From the sexist, coarse proprietor of Hobsons Boot Shop to the forthright, ambitious and uppish Maggie, Lean has, with the aid of some fantastic casting, excellently captured the unique characteristics of each character: the drunken pompousness of Henry Horatio Hobson, the cold sternness of old maid Maggie Hobson, the childlike innocence of Willie Mossop. The adaptation follows the play almost word for word, as well as the occasional addition by producer, director and screenwriter Lean. Charles Laughton, John Mills and Brenda de Banzie (as Hobson, Maggie and Willie) all give outstanding performances, portraying their characters perfectly. When reading the play, images are conjured up in the mind, and these images seem to have been projected onto the Silver Screen in the form of Laughton, Mills and de Banzie. Even the minor roles ...
This thesis investigated the effect of visuomotor and working memory 1) task difficulty and 2) multitasking on dynamic functional connectivity in the brain. Studies have only recently begun to investigate functional connectivity within the scope of concurrent dual task or varying task difficulty conditions (Cocchi, Zalesky, et al. 2011; Rietschel et al. 2012). A series of EEG recordings were conducted during execution of visuomotor or working memory tasks within a novel paradigm using BCI2VR custom MATLAB toolbox. Functional connectivity was correlated with task-related coherence (TRCoh) analysis between two task conditions involving either variation in task difficulty or concurrent execution during multitasking within the delta (0 - 4 Hz), theta (4 - 8 Hz), alpha (8 - 12 Hz), beta1 (12-16 Hz), beta2 (16 - 20 Hz) and beta3 (20 - 24 Hz) frequency bands. An increase in coherence was observed with increased cognitive load, during both increased task difficulty and multitasking, in all frequency bands
In the context of performance optimizations in multitasking, a central debate has unfolded in multitasking research around whether cognitive processes related to different tasks proceed only sequentially (one at a time), or can operate in parallel (simultaneously). This review features a discussion of theoretical considerations and empirical evidence regarding parallel versus serial task processing in multitasking. In addition, we highlight how methodological differences and theoretical conceptions determine the extent to which parallel processing in multitasking can be detected, to guide their employment in future research. Parallel and serial processing of multiple tasks are not mutually exclusive. Therefore, questions focusing exclusively on either task-processing mode are too simplified. We review empirical evidence and demonstrate that shifting between more parallel and more serial task processing critically depends on the conditions under which multiple tasks are performed. We conclude that
The ARA team conducted a human factors assessment and evaluation of plans for redesign and build of a section of the CCHMC NICU (the Interim Build). Based on systematic data collection and analysis, we recommended a number of alterations to the design plan to optimize patient care and safety.

Interruptions and multitasking are two afflictions that take a tremendous toll on our ability to focus, complete tasks, and be productive. Our own research on interruptions shows that the recovery time, that is, the time it takes an individual to return to a task after being interrupted, can be as much as 10 to 20 times the length of the original interruption. This means a 30 second interruption can result in an average of five minutes of recovery time, and that is optimistically assuming that one returns to the original task and does not abandon it.. Its already been established that multitasking is not really possible for the human brain to engage in with any efficiency; instead, it is really just a series of interruptions, or task switches. Multitasking results in lowered efficiency in all of the tasks being performed: there is no substitute for focused thinking on a single task.. New research from the University of California, San Francisco, that was published this week in the Proceedings ...

Finish simple tasks.. Always complete easy tasks without switching between tasks. Switching between simple tasks wastes time because the information gets jumbled, and we have to start the process all over again. Bottom line: Dont try to do two simple tasks at once.. Break up complex tasks.. Complex tasks like building a budget differ from simple ones: You can complete them more quickly and efficiently by breaking them up. Studies show that people who had to complete challenging tasks did so more effectively when they took a two-minute break and worked on something completely different -- for example, doing a crossword when trying to finish your taxes. Build willpower.. Willpower is key to efficiency -- and just like the muscles in your body, if you exercise it more frequently, you can improve it. Hone your willpower by breaking a routine like driving the same way to work or by giving up a bad habit like junk food for a week. Willpower gets depleted when you use it too much -- which is why ...

Iatrogenic illness and injury are a major source of morbidity and mortality for hospitalized patients. However, little is known about the incidence, nature, and causes of adverse medical events. The objective of this project was to develop a survey that could be used to assess adverse medical events. The survey was designed to obtain systematic information about adverse medical events. The critical incident technique was used to develop the Computerized Critical Incident (CCIT) survey. A test version of the survey (CCIT-I) was installed in the Intensive Care Unit of a major military hospital; 482 incident reports were collected. The survey system was positively received by the staff and the reports resulted in a number of corrective actions. The survey was revised to correct several problems. The second version of the survey (CCIT-II) was evaluated by subject matter experts. The feedback provided by the subject matter experts were used as the basis for a second revision. This resulted in the third,

Techniques for inspecting the usability of groupware applications have recently been proposed. These techniques focus on the mechanics of collaboration rather than the work context in which a system is used, and offer time and cost savings by not requiring actual users or fully-functional prototypes. Although these techniques are valuable, adding information about task and work context could improve the quality of inspection results. We introduce a method for analysing group tasks that can be used to add context to discount groupware evaluation techniques. Our method allows for the specification of collaborative scenarios and tasks by considering the mechanics of collaboration, levels of coupling during task performance, and variability in task execution. We describe how this type of task analysis could be used in a new inspection technique based on cognitive walkthrough.. ...

A task is dependent on another task when it has a Dependency set to another task ID. That is, if task 208 depends on task 54, it has Dependency set to 54, and task 54 must be completed in order for 208 to complete. The Completed Checkbox cannot be set on a task unless its dependency is completed first. In the edit field, manually enter the task ID of another task. Multiple IDs can be separated with a comma to indicated all of the other tasks must be completed before the current task. The eyeglasses (look at) icon in the edit field allows the grid selection to jump from a dependent task to its first dependency (no others). In the grid, tasks with a dependency have a small ToDoList icon in the , , column. A task with other tasks dependent on it does not have a link to its dependent tasks.

Abstract: Humans are routinely asked to evaluate the performance of other individuals, separating success from failure and affecting outcomes from science to education and sports. Yet, in many contexts, the metrics driving the human evaluation process remain unclear. Here we analyse a massive dataset capturing players evaluations by human judges to explore human perception of performance in soccer, the worlds most popular sport. We use machine learning to design an artificial judge which accurately reproduces human evaluation, allowing us to demonstrate how human observers are biased towards diverse contextual features. By investigating the structure of the artificial judge, we uncover the aspects of the players behavior which attract the attention of human judges, demonstrating that human evaluation is based on a noticeability heuristic where only feature values far from the norm are considered to rate an individuals performance ...
The intention of this study was fundamentally to identify whether there was a need to revise the curricula of study for the various categories of nurses, MCHNs, and MAs/MTs, so that graduates were prepared to perform each of the tasks that were expected of them, in whatever health facility they were assigned. We conducted a full assessment of the content included in the curricula of study for all six cadres, and a field study of tasks actually performed in the workplace, to identify those items of knowledge and skill that were the (then current) expected outcomes of pre-service education for the two pathways of study for the six cadres of health workers, so that it was possible to know whether any cadre was providing services outside of the scope of practice.. The present article focuses only on the findings from the field study (the skills survey) that documented the frequency of tasks actually performed by any of the six cadres in any of the types of health facilities to which they were ...
This article examines the perceptions and performance of a group of people with Down syndrome. This quality of life research is based on a six year study and compares the individuals performance with others with developmental disabilities. Twenty-seven people with Down syndrome ranging in age from 18-43 took part in the project and received individually chosen intervention for the last three years of the study. Over the six years, their Verbal IQ increased significantly. They also made significant gains in applying reading, writing and numerical skills in social contexts. Surprisingly, social behaviour and performance in a work setting declined after community training according to the rating of service providers, suggesting that training leads to gains in behaviour which are useful in the community, but less valued in traditional agency services. Individuals tended to be more dissatisfied after intervention as they became more aware of their needs and therefore more critical of their environment.

Following my attitude adjustment, It isnt cheating - it is collaboration, what do my tests look like now? We have a two-part exam (like I have seen at http://blogs.ubc.ca/wpvc/two-stage-exams/), in which students first complete an individual exam. They download a PDF of the exam, annotate it, and return it to me while were all in the classroom. There is no talking, although it is open-digital-textbook and open-internet (no print materials allowed). As at UBC, I made the individual exam worth most of the test points (~80% in my case). This helps assuage fears about how group performance might impact individual performance. Additionally, the individual exams incorporate most Blooms levels. The goal of this 15-minute portion of the exam is to distinguish students who have not prepared at all (the D and F students, say) from the other students. Students who have not studied might spend quite a bit of time looking up simple factual information and not earn many points in this relatively quick ...

We present novel evidence for specific, disruptive effects of multi-step task demands on the production of everyday life tasks in two patients with Action Disorganization Syndrome (ADS). Experiment 1 demonstrated that the patients were impaired at carrying out everyday life tasks but improved when they instructed the examiner to perform the tasks. Experiments 2 and 3 showed that the patients improved in their own performance when the demands were reduced - by eliminating the need to use their own task schema (Experiment 2) and by reducing the need for error monitoring (Experiment 3). Experiment 4 reduced sequential effects in task performance further by having patients perform the same individual actions as before but now out of the task context. The data indicate that ADS patients are vulnerable to multiple demands made during the performance of everyday life tasks and show abnormal, disruptive effects of three specific factors: (i) using a self-driven schema, (ii) error monitoring and (iii) the

Nearly any task requires multitasking expertise as just about any task needs workers who is able to effectively switch between multiple tasks productively, thereby making multi tasking critical in different profession. The cabability to multi-task proficiently and deal with changes in points clearly shows that a worker has very good time control. Unfortunately, period management is definitely difficult to learn for some people and even more difficult to achieve for others. The average employee is often too busy becoming a successful multitasker. There are many causes of this, including limited physical skills, lack of confidence and laziness. The inability to multi-task stems mostly from too little of organizational expertise. It is likely that if the workspace consists of just a single computer and one taskbar for inputting, then you are definitely not conducive to effective multi tasking skills. Subsequently, many individuals get discouraged with the inefficiency of their work place and give ...

An improved method and apparatus for embedding a real-time multi-tasking kernel in a non-real-time operating system is disclosed. Through encapsulating a real-time kernel into the interrupt handling environment of a non-real-time operating system, such as Windows , the method of the present invention allows for an entire real-time environment to be supported within the operating system. The scheduler of the real-time kernel supports multiple threads of execution all running at higher priority than the application tasks. By using synchronization mechanisms of the operating system, e.g. VxD events in enhanced mode Windows , the real-time tasks are able to make use of system services of the operating system. Real-time tasks not requiring system services execute more quickly from interrupt mode. Real-time tasks requiring system services execute partially from interrupt mode and partially from event mode.

The purpose of this study is to begin to explore which function identification methods work best for specific tasks. We use a three-level within-subject study (n = 78) to compare three strategies for identifying functions: energy-flow, top-down, and enumeration. These are tested in a product dissection task with student engineers who have minimal prior experience. Participants were asked to dissect a hair dryer, power drill, and toy dart gun and generate function trees to describe how these work. The function trees were evaluated with several metrics including the total number of functions generated, the number of syntactical errors, and the number of unique (relevant and nonredundant) functions. We found no statistical, practical, or qualitative difference between the trees produced by each method.

The purpose of this study is to begin to explore which function identification methods work best for specific tasks. We use a three-level within-subject study (n = 78) to compare three strategies for identifying functions: energy-flow, top-down, and enumeration. These are tested in a product dissection task with student engineers who have minimal prior experience. Participants were asked to dissect a hair dryer, power drill, and toy dart gun and generate function trees to describe how these work. The function trees were evaluated with several metrics including the total number of functions generated, the number of syntactical errors, and the number of unique (relevant and nonredundant) functions. We found no statistical, practical, or qualitative difference between the trees produced by each method. This suggests that the cognitive load for this task for novices is high enough to obscure any real differences between methods. We also found some generalized findings through surveys that the most ...
Caution: as defined, we should expect performance on this task to be bad. Quickselect is optimized for selecting a single element from a list, with best-case performance of O(n) and worst case performance of O(n^2). If we use it to select most of the items from a list, the overall task performance will be O(n^2) best case and O(n^3) worst case. If we really wanted to perform this task efficiently, we would first sort the list and then extract the desired elements. But we do not really want to be efficient here, and maybe that is the point. Further caution: this task asks us to select the first, second, third, ... up to the tenth largest member of the vector. But we also cannot know, apriori, what value is the first, second, third, ... largest member. So to accomplish this task we are first going to have to sort the list. But We Will Use Quickselect - that is the specification, after all. Perhaps this task should be taken as an illustration of how silly specifications can sometimes be. We need ...

Smart teams begin new design projects by getting to know their customers through design research. The best ones build models of those customers, their goals, their behaviors, and/or their environments. Models like personas do an awesome job of describing what the customers world looks like today. However, building models of customers and their work is only a means to the end of designing great products. Many teams struggle with using research models to inspire design. Its just too big of a jump from a persona writeup to a new product concept.. The context scenario bridges this gap. A good context scenario clearly articulates a working hypothesis of how the customers lives will improve when the new product* exists. Unlike a workflow or task analysis, a context scenario is an act of design-it imagines the future, rather than describing the world as it is today. Because context scenarios can be created and iterated on very quickly, they are often the first design act the team undertakes.. (* - ...
