ABSTRACT

Game developers potentially convey socio-cultural values about gender through design choices. This study interpreted the designs of 11 purposively selected female game characters, developed by studios located in the United States and Japan, through the lens of ambivalent sexism. This social psychological theory posits that sexism consists of hostile and benevolent attitudes about women. Two themes emerged across characterizations: bodies as objects, bodies as weapons and (in)dependence. Both consisted of empowering qualities paired with problematic beliefs about women. This analysis contributes to interdisciplinary literature by using an empirical perspective to interpret gender representations in video games.  相似文献

ABSTRACT

The aims of this study were to identify profiles of sedentary behaviour (SB) patterns, based on leisure-time self-reported SB modalities (screen, educative, social, and relaxing) and to evaluate changes in these profiles over 2 years among Spanish youth aged 8–18 years. Latent profile analysis (LPA), a data-driven analytic approach, was used to identify groups of boys and girls (n = 1553; 48% girls; mean±SD age: 12.56 ± 2.49 y) with distinct SB profiles using the SB modalities (time/d) as input variables. Latent transition analysis, an extension of LPA that uses longitudinal data, was used to analyse 2-year changes in these profiles. At baseline, four and three SB profiles were found among boys (labelled: screen, educative, social, and relaxing) and girls (labelled: screen/social, educative, and relaxing), respectively. Overall, more girls (range: 48%-67%) had the same profile over time, than boys (40%-52%). Participants with a screen or relaxing SB profile at baseline were more likely to have an educative profile after 2 years. Youth with a social and an educative SB profile at baseline were more likely to transition to profiles characterized by higher screen and social SB, respectively. Using a novel and person-centered approach, this study identified gender-specific SB profiles that were moderately stable over time.  相似文献   

A comparison of Australian and Chinese teachers' attributions for student problem behaviors     

Irene T. Ho 《教育心理学》2004,24(3):375-391

The present study compared Australian and Chinese teachers' causal attributions for student behavior. A total of 204 Australian teachers and 269 Chinese teachers rated the importance of four causes (ability, effort, family, teacher) of six student problem behaviors. Results showed that both groups of teachers attributed misbehaviors most to student effort and least to teacher factors. Chinese teachers emphasized family factors more while Australian teachers placed greater importance on ability. There was significant variation in attribution patterns for different types of problems, with effort attribution being equally and strongly emphasized across cultural contexts and behavior types. The results are interpreted in the light of how individualistic and collectivistic values influence teacher thinking, and implications for school‐based interventions for behavior problems are discussed.  相似文献   

Mechanisms mediating the relation between reading self-concept and reading comprehension     

Locher  Franziska Maria  Becker  Sarah  Schiefer  Irene  Pfost  Maximilian 《European Journal of Psychology of Education - EJPE》2021,36(1):1-20

Reading self-concept is an important predictor of reading comprehension and vice versa. However, the mechanisms that are at work in this relation have yet to be identified. In line with the self-enhancement approach, we propose that in the reading domain, amount of reading, book choice (text difficulty and book length), and intrinsic reading motivation should function as mediating variables in the relation between reading self-concept and reading comprehension. We tested this hypothesis with longitudinal data gathered from N = 405 German students in Grades 7, 8, and 9. The results showed that reading self-concept had a positive effect on reading comprehension, intrinsic motivation, book length, and amount of reading. However, indirect paths between reading self-concept and reading comprehension were found only for intrinsic motivation, not for amount of reading or book choice. The results are discussed in the context of students’ reading comprehension development, and consequences for research and education are derived.

The Dutch motor skills assessment as tool for talent development in table tennis: a reproducibility and validity study     

Irene R. Faber  Maria W. G. Nijhuis-Van Der Sanden  Marije T. Elferink-Gemser  Frits G. J. Oosterveld 《Journal of sports sciences》2015,33(11):1149-1158

A motor skills assessment could be helpful in talent development by estimating essential perceptuo-motor skills of young players, which are considered requisite to develop excellent technical and tactical qualities. The Netherlands Table Tennis Association uses a motor skills assessment in their talent development programme consisting of eight items measuring perceptuo-motor skills specific to table tennis under varying conditions. This study aimed to investigate this assessment regarding its reproducibility, internal consistency, underlying dimensions and concurrent validity in 113 young table tennis players (6–10 years). Intraclass correlation coefficients of six test items met the criteria of 0.7 with coefficients of variation between 3% and 8%. Cronbach’s alpha valued 0.853 for internal consistency. The principal components analysis distinguished two conceptually meaningful factors: “ball control” and “gross motor function.” Concurrent validity analyses demonstrated moderate associations between the motor skills assessment’s results and national ranking; boys r = ?0.53 (P < 0.001) and girls r = ?0.45 (P = 0.015). In conclusion, this evaluation demonstrated six test items with acceptable reproducibility, good internal consistency and good prospects for validity. Two test items need revision to upgrade reproducibility. Since the motor skills assessment seems to be a reproducible, objective part of a talent development programme, more longitudinal studies are required to investigate its predictive validity.  相似文献   

Discrimination of Biomechanically Possible and Impossible Hand Movements at Birth          下载免费PDF全文

The development of human body perception has long been investigated, but little is known about its early origins. This study focused on how a body part highly relevant to the human species, namely the hand, is perceived a few days after birth. Using a preferential‐looking paradigm, 24‐ to 48‐hr‐old newborns watched biomechanically possible and impossible dynamic hand gestures (Experiment 1, N = 15) and static hand postures (Experiment 2, N = 15). In Experiment 1, newborns looked longer at the impossible, compared to the possible, hand movement, whereas in Experiment 2 no visual preference emerged. These findings suggest that early in life the representation of the human body may be shaped by sensory‐motor experience.  相似文献   

Optimal sampling frequency in recording of resistance training exercises     

Paolo Bardella  Irene Carrasquilla García  Marco Pozzo  Julio Tous-Fajardo  Eduardo Saez de Villareal 《Sports biomechanics / International Society of Biomechanics in Sports》2017,16(1):102-114

The purpose of this study was to analyse the raw lifting speed collected during four different resistance training exercises to assess the optimal sampling frequency. Eight physically active participants performed sets of Squat Jumps, Countermovement Jumps, Squats and Bench Presses at a maximal lifting speed. A linear encoder was used to measure the instantaneous speed at a 200 Hz sampling rate. Subsequently, the power spectrum of the signal was computed by evaluating its Discrete Fourier Transform. The sampling frequency needed to reconstruct the signals with an error of less than 0.1% was f_99.9 = 11.615 ± 2.680 Hz for the exercise exhibiting the largest bandwidth, with the absolute highest individual value being 17.467 Hz. There was no difference between sets in any of the exercises. Using the closest integer sampling frequency value (25 Hz) yielded a reconstruction of the signal up to 99.975 ± 0.025% of its total in the worst case. In conclusion, a sampling rate of 25 Hz or above is more than adequate to record raw speed data and compute power during resistance training exercises, even under the most extreme circumstances during explosive exercises. Higher sampling frequencies provide no increase in the recording precision and may instead have adverse effects on the overall data quality.  相似文献   

Hopf bifurcation and synchronization of a five-dimensional self-exciting homopolar disc dynamo using a new fuzzy disturbance-observer-based terminal sliding mode control     

Zhouchao Wei  Amin Yousefpour  Hadi Jahanshahi  Uǧur Erkin Kocamaz  Irene Moroz 《Journal of The Franklin Institute》2021,358(1):814-833

Having found hidden hyperchaos in a 5D self-exciting homopolar disc dynamo, we study the existence of a Hopf bifurcation, which leads to unstable limit cycles bifurcating from a stable equilibrium. Hidden chaos with only stable equilibria can be observed from the Hopf bifurcation: a typical way to enable hidden attractors to be located. We then provide a new fuzzy controller, and a fast fuzzy disturbance observer, based on terminal sliding mode control for synchronization of the hyperchaotic system. Fuzzy inference is considered to weaken the chattering phenomena. Using Lyapunov stability theory, the stability of the closed-loop system is proved. Finally, simulations of synchronization are illustrated to show the efficient performance of the designed control method via external disturbances and dynamic uncertainties.  相似文献

Core‐explore‐more: A structure for planning enrichment activities     

Irene Hannigan 《Roeper Review》2013,35(3):142-144

A framework for planning enrichment activities within a self‐contained classroom is described through the structure of Core‐Explore‐More. At the Core level, activities systematically introduce students to concepts, generalizations and basic skills related to an important curriculum theme. Explore activities allow follow‐up experiences for those students who have been excited and motivated by what they have done at the core level. More activities require greater commitment and individual student initiative because of their specialization.  相似文献
