The eye-tracking method was used to assess the influence of detailed, colorful illustrations on reading behaviors and learning outcomes. Based on participants’ subjective ratings in a pre-study, we selected eight one-page human anatomy lessons. In the main study, participants learned these eight human anatomy lessons; four were accompanied by detailed illustrations, and the other four were accompanied by simplified illustrations. Participants completed a comprehension test and an evaluation questionnaire after reading each lesson. The results showed that detailed and simplified illustrations were equally effective in terms of learning outcomes. Eye-tracking data indicated that the detailed illustrations attracted attention in the initial learning stage and received more visual attention during the overall learning process. Notably, correlation analysis revealed that spending a greater proportion of time re-inspecting the simplified illustration was associated with higher test performances. By contrast, greater proportion of time spent re-inspecting the detailed illustration was not significantly correlated with learning outcomes. The results suggest that detailed illustrations could influence the learning process, and may support learning differently compared with simplified illustrations. 相似文献

Given the immense power of the mass media, how they selectively represent the world requires investigation and critique. Selective representation refers basically to the promotion and reinforcement of certain ways of thinking (Fairclough 1995b, Lull 1995). This paper examines, by way of linguistic analysis, particular representations of the school experience in three popular English teenage magazines in Singapore. It concentrates on the implicit ‘commonsense’ assumptions about school which underlie common teenage discourse on such popular topics as having fun, being cool, looking good, etc. 相似文献

The aim of this study was to determine the mechanical variables that govern success of the Hecht vault. The participants were 122 male gymnasts from 30 countries performing the vault at the 1995 World Gymnastics Championships. The vaults were filmed using a Photosonics 16-mm motion picture camera operating at 100 Hz. Approximately 80 frames were digitized for each vault analysed. The method of Hay and Reid was used to develop a theoretical model to identify the mechanical and physical variables that determine linear and angular motions of the vault. Correlational analysis was used to establish the strength of the relationship between the causal mechanical variables identified in the model and the judges' scores. Significant correlations (P ? 0.005) indicated that the following were important determinants of success: large horizontal and vertical velocities at take-off from the board and the horse; large vertical and angular distances of pre-flight; large vertical impulses of high force and short duration exerted on the horse and the resulting large changes in vertical velocity on the horse; and large horizontal and vertical distances and long times of post-flight. Of the 18 significant variables identified in the present study, the angular distance of pre- and post-flights, the horizontal velocity and angular momentum at take-off from the horse, and the average moment of inertia and duration of post-flight collectively accounted for 57% of the variation in the judges' scores. 相似文献

AbstractThis study aimed to elucidate the movements requiring greater trunk accelerations and its frequencies during badminton games, and compare the acceleration components among such movements. Trunk acceleration was measured using a triaxial accelerometer during badminton games. The moments that generated >4 G resultant acceleration were extracted, and movements consistent with the extracted moments were identified. We calculated the extracted movement ratio and frequency and compared the resultant, mediolateral, vertical and anteroposterior accelerations between the top five extracted movements. There were 1,342 movements that generated >4 G [mean, 7.72 (95% confidence interval, 7.31–8.14) cases/min]. The top five movements were lunging during underhand strokes with the dominant hand side leg, landing after overhand strokes on the dominant and non-dominant hand side leg, and cutting from a split step using the dominant and non-dominant hand side leg. Landing on the dominant hand side leg had a greater resultant acceleration than the other movements and had the greatest impact during the badminton game. Lunging during underhand strokes on the dominant hand side leg had greater mediolateral acceleration than the other movements. These results reflected the properties of badminton. 相似文献

HLA association with drug-induced liver injury has recently been pointed out about multiple medicines. The aim of this study was to evaluate relationship between HLA gene and liver injury related to Baikal skullcap-containing Kampo medicines (BSCK). We previously examined HLA genes in 3 cases of BSCK-induced liver injury. Recently we could encounter 2 cases diagnosed as “definitely-related case” of BSCK-induced liver injury. HLA genes of the 2 cases were analyzed by Sequencing Based Typing method with Next Generation Sequencer at HLA Laboratory in Kyoto. HLA-DPA1*02:02:02 and DPB1*05:01:01 were observed in the 2 cases: concordance was not observed in HLA-A, B, C, DRB1, DRB4, DQA1, or DQB1. The previous 3 cases of BSCK-induced liver injury had the same allele type to the 2 cases only in HLA-DPA1. Putting all these together, HLA-DPA1*02:02:02 was observed in common among 5 cases of BSCK-induced liver injury. HLA-DPA1*02:02:02 is possibly associated with BSCK-induced liver injury. 相似文献

ABSTRACTA possible link between soccer-specific injuries, such as groin pain and the action of hip adductor muscles has been suggested. This study aimed to investigate neuromuscular activation of the adductor magnus (AM) and longus (AL) muscles during instep and side-foot soccer kicks. Eight university soccer players performed the two types of kick at 50%, 75% and 100% of the maximal ball speed. Surface electromyography (EMG) was recorded from the AM, AL, vastus lateralis (VL) and biceps femoris (BF) muscles of both kicking and supporting legs and the kicking motions were three-dimensionally captured. In the kicking leg, an increase in surface EMG with an increase in ball speed during instep kicking was noted in the AM muscle (p < 0.016), but not in AL, VL or BF muscles (p > 0.016). In the supporting leg, surface EMG of both AM and AL muscles was significantly increased with an increase in the ball speed before ball impact during both instep and side-foot kicks (p < 0.016). These results suggest that hip adductor muscles markedly contribute to either the kicking or supporting leg to emphasise the action of soccer kicks. 相似文献

The present study examined the nature of the “avoidance” response in goldfish under the linear presentation procedure (Zerbolio, 1981). With this procedure, shuttling behavior occurring during the presentation of the trial stimulus produces either CS? or CS+, and further occurrence of shuttling within the trial interval (10 sec) changes the value of CS from negative to positive, or vice versa. If the fish remains in the compartment when the prevailing cue state is CS? at the end of the interval, shock can be avoided. With this procedure fish responded to the CS+ more than to the CS? and avoided shock. But fish in one of two control groups, in which responses had no effect in changing the cue state from CS+ to CS?, or vice versa, also showed a clear differentiation. The results were generally in line with the view that the “avoidance” response in fish is acquired through classical conditioning. The contribution of classical conditioning to the acquisition of avoidance response is discussed. 相似文献
