This study aimed to investigate the effects of sleep deprivation on postural control, subjective fatigue assessment and psychomotor performance, and to assess the efficiency of an objective post urographic test as an indicator of mental fatigue. Postural sway using static posturography (Romberg's test), subjective fatigue assessment (Stanford Sleepiness Scale) and psychomotor performance (Sternberg dual-task test) were assessed in 12 subjects before and after 24 h of sustained wakefulness. After sustained wakefulness, the Romberg test parameters of circumference area and rectangle area with the eyes-closed, and standard deviation in the anterior-posterior direction with the eyes-open were significantly higher compared with baseline values (before sustained wakefulness). Subjective fatigue assessment scores were also significantly increased, while psychomotor performance was unchanged. Sleep deprivation can arouse a feeling of fatigue and can affect postural stability, hence an objective posturographic test score may be useful as an indicator of mental fatigue.

“…[15] In this study, we had correlated the duration of SD with subjective sensation of sleepiness using the pictorial sleepiness scale. [9] There is no significant effect of SD on sleepiness score after 6 h of SD (P > 0.05) as shown in Table 1.…”

Background: Prolonged resident duty hours may affect patient care. There are no restrictions to the amount of hours a resident can work which may lead to medical errors and lapses in patient care. Aims and Objectives: The purpose of this study was to prospectively evaluate the effect of sleep deprivation (SD) on finger dexterity at different intervals of SD during the residents' on-call period and to identify the duration after which these effects begin. We further tested if this decline correlated with the subjective assessment of sleepiness. Materials and Methods: The finger dexterity was measured by the O'Connor dexterity apparatus, and subjective sleepiness assessment was carried out using pictorial sleepiness scale in 30 resident doctors at 6 h intervals during their on-call period which lasted for 24 h. Results: The finger dexterity was significantly decreased at the end of the 24 h duty period as compared to the baseline. This deterioration began after being on-call for 12 h and progressed thereafter. The changes in finger dexterity correlated negatively with the subjective sleepiness assessment. Conclusion: 24 h of SD during on-call duty significantly decreases the finger dexterity in resident doctors. This might be a major cause of medical errors and hamper patient safety.

“…The effort required to produce a next move may "spill over" into the phase after the next move has been given (in the case that the student requests a bottom-out hint) such that the student does not study the next move in these circumstances (i.e., when they reach the bottom-out hint after struggling with the step) as much as they do when the example is given up front (see also Schnotz 2010). This "spill over" could be general load/ fatigue like hemoglobin depletion (e.g., Grandjean 1979;Watanabe et al 2002) or performance orientation (Dweck and Leggett 1988;Elliot and McGregor 2001).…”

Recent studies have tested the addition of worked examples to tutored problem solving, a more effective instructional approach than the untutored problem solving used in prior worked example research. These studies involved Cognitive Tutors, software designed to support problem solving while minimizing extraneous cognitive load by providing prompts for problem sub-goals, step-based immediate feedback, and context-sensitive hints. Results across eight studies in three different domains indicate that adding examples to Cognitive Tutors is beneficial, particularly for decreasing the instructional time needed and perhaps also for achieving more robust learning outcomes. These studies bolster the practical importance of examples in learning, but are also of theoretical interest. By using a stronger control condition than previous studies, these studies provide a basis for refining Cognitive Load Theory explanations of the benefits of examples. Perhaps, in addition to other reasons, examples may help simply because they more quickly provide novices with information needed to induce generalized knowledge. Keywords Worked examples . Cognitive tutors . Cognitive load theoryIn recent years, a considerable number of studies have explored the conditions under which examples aid in acquiring cognitive skills (for a review, see Atkinson et al. 2000;Renkl 2005Renkl , 2010. Among other things, researchers have discovered (1) that examples are more effective than problems in the early stages of skill acquisition, (2) that problems are more effective in later stages (e.g., Kalyuga et al. 2003), (3) that interleaving examples and problems (i.e., example-problem pairs) is more effective than presenting examples and problems in blocks (Trafton and Reiser 1993), (4) that a gradual step-by-step fading of Educ Psychol Rev
