Extraneous Load

AbstractStudies showing improved learning performances for students who take notes collaboratively have speculated that sharing this task among group members may reduce the extraneous cognitive burden placed on each member. Therefore, a study (n = 171) was conducted in the context of a flipped scientific writing course to examine the effects of collaborative note-taking on student’s levels of cognitive load. Students in the course were divided into two groups, with members of the treatment group being directed to take collaborative notes in a shared online document and members of the control group receiving no such instructions. The study also measured the level of collaboration the collaborative note-takers engaged in, as well as the level of completeness of the notes that they produced. The results showed that, firstly, the treatment group reported higher levels of both germane and extraneous cognitive load compared to those of the control group, meaning that collaborative note-takers experienced higher levels of understanding of course content as well as increased confusion. Secondly, the level of collaboration was positively and significantly correlated with levels of germane load (understanding), but not with extraneous load (confusion). Thirdly, no correlation was found between completeness of notes and cognitive load. Accordingly, the authors suggest that collaborative note-taking is worthwhile, as the gains to students’ understanding of course content outweigh the disadvantages of increased confusion.

Abstract Background Self-rated health (SRH) is one of the most commonly used summary measures of overall health and well-being available to population scientists due to its ease of administration in large-scale surveys and to its efficacy in predicting mortality. This paper assesses the extent to which SRH is affected by its placement before or after questions about bodyweight on a survey, and whether differences in placement on the questionnaire affects SRH’s predictive validity. Methods I assessed the validity of SRH in predicting the risk of mortality by comparing outcomes of sample members who were asked to rate their health before reporting on their bodyweight (the control group) and sample members who were asked to rate their health after reporting on their bodyweight (the treatment group). Both the control and treatment group were randomly assigned via an experiment administered as a module in a nationally representative sample of adults in the USA in 2019 (N = 2523). Results The odds of reporting a more favorable appraisal of health are 30% lower for sample members who were in the treatment group when compared with the control group. Additionally, the SRH of treatment group members is significantly associated with their risk of mortality, while the SRH of control group members is not. Conclusion The findings from this study suggest that for researchers to maximize the utility of SRH, closer attention needs to be paid to the context of the survey within which it asked. SRH is highly sensitive to the questions that precede it, and this sensitivity may in turn mischaracterize the true health of the population that the survey is intending to measure.

This study was intended to determine the effect of the presence of tutors in the learning video on cognitive load and academic achievement. The design used in this study was the posttest control group design. The subjects of this study were 30 students of eleventh-grade science of senior high school number 1 Ungaran. The measurements of the data were carried out using cognitive load questionnaires, eye-tracking measurements, and biological matter of reproductive materials (prior knowledge and posttest teaching). The result of analysis using the Multivariate analysis of variance test showed that the presence of tutors in the learning video did not have a significant effect on extraneous load (F(2.27)=2.6, p>0.05), the presence of tutors in the learning video did not have a significant effect on germane load in the subjective measurements (F(2.27)=0.06, p>0.05), however, the presence of tutors in the learning video has a significant effect on the objective measurements (F(2.27)=24.47, p<0.05) and (F(2.27)=28.14, p<0.05). Furthermore, the presence of tutors in the learning video has a significant effect on academic achievement with (F(2.27)=3.38, p<0.05). The findings of this study proved that there were effects of the presence of tutor in the learning video on germane load and academic achievement.

Working memory is critical for learning but has a limited capacity for processing new information in real time. Cognitive load theory is an evidence-based approach to education that seeks to minimize the extraneous (unnecessary) load on working memory to avoid overloading it. The “seductive details effect” postulates that extraneous load can come from instructional design materials that attract interest but are unrelated to, and impair, learning. Presentation packages, such as Microsoft PowerPoint, have built-in decorative animated “GIFs” that are designed to make presentations more visually appealing. The aim of the study was to investigate the effect of such “decorative” animations on learning and working memory performance. We found that students were less able to recall content presented in the presence of a decorative but relevant animation compared with a still image. This effect was found with two different topics (human physiology and enzyme kinetics). Compared with still images, students also found it harder to remember animations themselves, and the self-reported mental workload required to remember them was higher. These results show that decorative animations are seductive details and are thus a source of extraneous cognitive load.

The Impact

A test was done to see if reading a newspaper which consistently overrepresents foreigners as criminals strengthens the automatic association between foreign country and criminal in memory (i.e., implicit cultivation). Further, an investigation was done to find out if reading articles from the same newspaper produces a short-term effect on the same measure and if (1) emotionalization of the newspaper texts, (2) emotional reactions of the reader (indicated by arousal), and (3) attributed text credibility moderate the short-term treatment effect. Eighty-five participants were assigned to one of three experimental conditions. Participants in the control group received short factual crime texts, where the nationality of the offender was not mentioned. Participants in the factual treatment group received the same texts, but the foreign nationality was mentioned. Participants in the emotionalized treatment group received emotionalized articles (i.e., texts which are high in vividness and frequency) covering the same crimes, with the foreign nationality mentioned. Supporting empirical evidence for implicit cultivation and a short-term effect was found. However, only emotionalized articles produced a short-term effect on the strength of the automatic association, indicating that newspaper texts must have a minimum of stimulus intensity to overcome an effect threshold. There were no moderating effects of arousal or credibility pertaining to the impact on the implicit measure. However, credibility moderated the short-term effect on a first-order judgment (i.e., estimated frequency of foreigners of all criminals). This indicates that a newspaper’s effect on the strength of automatic associations is relatively independent from processes of propositional reasoning.

The Difference

Background: Shoulder-hand syndrome (SHS) refers to a syndrome causing sudden edema, shoulder pain and limited hand function. Qingpeng ointment, a kind of Tibetan medicine, can reduce swelling, relieve pain, tonify stagnation and clear the meridians, which is consistent with the pathological mechanism of SHS after stroke. Therefore, if clinical trials can be used to explore the effectiveness of Qingpeng ointment for treatment of poststroke SHS and promote its application in clinical medicine, this is of specific significance for the treatment of poststroke SHS. Objective: To investigate the clinical efficacy and safety of Qingpeng ointment in the treatment of poststroke SHS. To provide an objective basis for a better therapeutic treatment for poststroke SHS． Method: A prospective, randomized, controlled study was conducted. This study recruited 120 patients with poststroke SHS who met the inclusion criteria. They were randomized into the treatment group and the control group, with 60 patients allocated to each group. The treatment group received routine medical treatment and rehabilitative care after using the Qingpeng ointment, while the patients in the control group received only routine treatment without the ointment. All patients received clinical assessment with the Visual Analogue Scale (VAS), measurement of the range of motion (ROM) of the upper-limb joints, the Fugl-Meyer Assessment of Upper Extremity (FMA-U) and the Modified Barthel Index Score (MBI) before and after the whole treatment. Results: After 4 weeks of treatment, the VAS scores of both groups were decreased significantly (P＜0.05), and the difference between the two groups was statistically significant (P < 0.05). There is no statistical significance for the difference between the treatment group and control group in terms of the FMA-U and MBI scores and the forward bend, backward, outstretch, external rotation and pronation angles after treatment. The increases in the values of VAS, FMA-M and MBI in the treatment group were greater than those in the control group, and the difference was statistically significant (P < 0.05). The increases in the values of the forward bend, outreach and external rotation angles in the treatment group were greater than those in the control group, and the difference was statistically significant (P < 0.05). Conclusion: The treatment group showed better results than the control group in terms of the relief of pain symptoms, the improvement of motor function and the improvement of the activities of daily living for patients with shoulder-hand syndrome after cerebral hemorrhage. Qingpeng ointment is effective and safe in treating poststroke SHS.

This study was initiated on 24 prepubertal Holstein x Kankrej crossbred heifers of nearly identical age (7-9 months) and body weight (130-140 kg) at University farm to evaluate the effect of high plane of nutrition on blood biochemical and minerals profile and the age at puberty. Twelve heifers were managed under routine farm feeding (control) and the rest 12 under ideal optimum feeding regime (treatment) that included extra 1 kg concentrate, 30 g min mix and ad-lib dry fodder. The body weight and ovarian ultrasonography together with blood sampling was carried out at monthly interval from 10 to 18 months of age to study the ovarian dynamics and blood biochemical changes. High plane of nutrition to growing heifers was beneficial in reducing the age of onset of puberty (by 2-3 months) compared to routine farm fed group. The mean plasma total protein and cholesterol concentrations showed a rising trend with significant variations from 10 to 16 months of age, where it got mostly stabilized indicating adult profile. The activity of enzymes GOT and GPT also rose gradually and significantly from 10 months till 14-15 months of age, and thereafter it remained more or less static till 18 months of age. The levels of both these enzymes were higher, with lower protein and cholesterol, in control than the treatment group from 15-16 months of age onwards. The mean plasma levels of both calcium and phosphorus increased gradually and significantly with advancing age till 16-17 months of age, with little higher values in supplemented than a control group. The plasma levels of zinc, iron, copper, and cobalt also showed rising trend with significant differences between 10th and 12th-14th months of age, and from 15th to 18th months of age the levels were statistically the same in all the groups with slightly higher values in the treatment group.

An on-farm trial for 90 days was conducted at four tribal villages to assess the effect of chelated mineral mixture (CMM) supplementation on blood biochemistry as well as hormonal and mineral status, nutrient intake and reproductive performance of the repeat breeder buffaloes (n = 24). The animals selected were randomly divided into two groups of 12 animals each. The group T1 was control group (farmer’s feeding schedule), and T2 treatment group (T1 + CMM @ 50 g/animal/day). Blood collection was done at 0, 45 and 90 days of the experiment from both the groups for assessment of blood biochemical, hormonal and mineral status of the animals. Average DM, DCP and TDN intake in repeat breeder buffaloes calculated as per information collected from farmers were statistically similar among both the groups and were as per ICAR requirements of animals. Results revealed significant (p less than 0.05) improvement in hemoglobin, serum glucose, total protein, total cholesterol, progesterone, and macro (Ca, P)–micro (Zn, Fe, Cu, Co, Mn) mineral status of chelated mineral supplemented group as compared to control animals. The number of days taken for a successful conception in repeat breeder buffaloes as well as the cost of feeding was also reduced upon supplementation of CMM in T2 as compared to T1 group. The control group recorded a 22.12% higher cost of rearing than the treatment group during the experimental period. The findings revealed the beneficial role of cheated minerals supplementation in improving health, nutritional and reproductive status of repeat breeding buffaloes.
