The control of amplitude and direction in a bimanual coordination task

Bimanual coordination requires task-specific control of the spatial and temporal characteristics of the movements of both hands. The present study focused on the spatial relationship between hand movements when their amplitude and direction were manipulated. In the experiment in question, participants were instructed to draw two lines simultaneously. These two lines were instructed to be drawn in mirror symmetric or perpendicular directions of each other while the length was instructed to be the same or different. The coordinative quality of amplitude control was compared when the task required symmetric and asymmetric bimanual spatial coordination patterns. Results showed that the amplitude accuracy decreased when different amplitudes and/or directions had to be generated simultaneously. The coordinative quality of direction was also compared when the task required symmetric and asymmetric bimanual spatial coordination patterns. Unlike amplitude, the direction accuracy was largely independent of coordination symmetry/asymmetry of direction or amplitude. The results suggest that the coordinative quality of amplitude control does not only interfere with amplitude asymmetry, but it also interferes with direction asymmetry. Moreover, in bimanual coordination amplitude control is more vulnerable to the influence of direction control demands than vice versa.     

Internet of image things-discrete wavelet transform and Gabor wavelet transform based image enhancement resolution technique for IoT satellite applications

In image processing, image enhancement is a vital processing chore. The image enhancement can improve the image quality by removing either blur or any kind of noise in the image. Image enhancement technique is utilized in many applications, such as medical, satellite, agriculture, oceanography and so on. This paper focuses on the IoT satellite applications. Most of the satellite images are essential to have high resolution satellite images, low resolution images are majorly affected by absorption, scattering, spatial resolution and spectral resolution issues. For better resolution of these kinds of issued images, Discrete Wavelet Transform (DWT) based interpolation method, combination of DWT and stationary wavelet transform (SWT) methods, bicubic interpolation methods are utilized. However, DWT with SWT method is failed avoid distorted in the resultant images, the bicubic interpolation method is quite complex and cannot give a clear image. DWT based interpolation method lose linear features and unwanted oscillations are occurred and edges data is lost. Therefore, DWT and Gabor technique is proposed to overcome existing method issues. DWT is decomposed into multiple sub-bands; GWT is employed to minimize the loss of information in wavelet domain. The advantages of the GWT are less complexity, remove the noise, and also sharp the image. The proposed method of the PSNR, MSE is compared with existing methods by using the different satellite images.     

Do perceived autonomy-supportive and controlling teaching relate to physical education students' motivational experiences through unique pathways? Distinguishing between the bright and dark side of motivation

ObjectivesGrounded in Self-Determination Theory (SDT), this study examined the mediating role of students' experiences of need satisfaction and need frustration in associations between perceived teaching style and students' motivation and oppositional defiance in the context of physical education. Specifically, we tested an integrated model including both a ‘bright’ path from perceived autonomy-supportive teaching through need satisfaction toward autonomous motivation and a ‘dark’ pathway from perceived controlling teaching through need frustration toward controlled motivation, amotivation, and oppositional defiance.DesignCross-sectional study.MethodsTo investigate the proposed paths structural equation modeling was used in a sample of 499 secondary school students (44% boys, M_age = 15.77 ± 1.16).ResultsWe found that perceived autonomy-supportive and controlling teaching, as well as need satisfaction and need frustration, constitute different constructs relating distinctively to motivational outcomes. Consistent with the notion of a bright and dark path, perceived autonomy support was related primarily to autonomous motivation, with need satisfaction mediating this association, whereas perceived controlling teaching was related primarily to controlled motivation and amotivation, through need frustration. Perceived controlling teaching also displayed a direct and unique relationship with oppositional defiance.ConclusionsTo more accurately capture the detrimental effects of controlling teaching, this teaching dimension along with its consequences in terms of need frustration and motivational outcomes needs to be studied in its own right. It is also discussed that effective teacher training may raise awareness among teachers about the motivational risks associated with controlling practices.     

Une synthèse des formations et ressources disponibles pour encourager l’excellence dans l’enseignement de la psychologie dans l’enseignement supérieur au Royaume-Uni

This review considers the range of training and resources that are available to support excellence in the teaching of psychology in higher education in the UK. Various sources of support are reviewed, including both generic and specific mechanisms provided by either the Higher Education Academy (HEA) or the British Psychological Society (BPS). The training considered ranges from that provided for all new lecturers in the UK by their institutions, through to bespoke seminars and workshops delivered by the HEA and the BPS. Resources include written guidance, websites and sources of funding to support the development of teaching and learning. It is concluded that whilst there are currently some excellent resources available to support psychology teachers in higher education, recent changes to the HEA have created some uncertainty in the sector.     

Collective student characteristics alter the effects of teaching practices on academic outcomes

The goal of this study was to examine the influence of collective student characteristics (academic skills and task persistence at the beginning of first grade) and different teaching practices (child-centered, teacher-directed, and child-dominated) on the development of academic skills and task persistence during the first two years in school. We hypothesized that teaching practices would differentially impact the development of academic skills and task persistence depending on the collective needs of the classroom. Participants were 523 students (273 boys) from 32 classrooms across Estonia. By using multilevel modeling, we found several interactions indicating that both contextual influences are important in determining subsequent academic functioning and task persistence but that some teaching practices are more beneficial depending on the collective starting point of students. These findings highlight the importance of studying different contextual influences hand in hand when trying to understand what enhances young children's academic development.     

The changing influences on commuting mode choice in urban England under Peak Car: A discrete choice modelling approach

The phenomenon of Peak Car has been defined over the past eight years as a plateau or fall in the level of car use in urban areas. Although Peak Car research to date has relied on population-level data, such macro-level trends can be disaggregated into many individual travel decisions. This research uses English survey data collected by the Department for Transport (DfT) in 2009 to test a range of variables influencing choice of commuting mode in residents of urban England. The variables tested are subdivided into spatial, demographic, level of service, and attitudinal. Multinomial logistic regression is used to test these variables individually and then in combination, producing a multivariate discrete choice model of commuting mode choice. The choice between commuting modes is fourfold: car, bus, train, and active modes. The results suggest that the relationship between income and car use is changing, as higher incomes are found to be associated with increased odds of choosing to commute by train or active modes rather than the car when other factors are controlled for. Attitudes to buses and active modes are also found to be influential.     

Entraînement au monitoring métacognitif et performances à l’université

In French universities, only one out of two students is successful in his/her first year. The change of the working rhythm and the importance of self-regulated learning (relying on metacognition) can to a large extent explain these dramatic rates. Techniques have been developed to help students improve monitoring their activities. In this study, we adapted a method tested in previous research, and noticed positive effects on students’ performance. This intervention would be easy to implement in university classes, and would benefit students even more if generalized and complemented by techniques focused on more global aspects of metacognition and self-regulated learning.     

Self-determination theory based instructional interventions and motivational regulations in organized physical activity: A systematic review and multivariate meta-analysis

This study aimed to provide a quantitative synthesis of the effect of Self-determination theory (SDT) based instructional interventions on the motivational regulations of participants in organized physical activity. We conducted a systematic review and meta-analysis on experimental studies conducted before December 2021. The search using the online databases PsychINFO, PsychARTICLES, ERIC, SportDISCUS, and ProQuest Dissertations and Theses, and Google Scholar and other supplementary search strategies yielded 7774 articles, with 38 articles (142 effects and 12,457 participants) meeting the inclusion criteria. The articles were analyzed using a meta-analytic multivariate model. The study showed that SDT-based instruction had a positive heterogeneous small effect on intrinsic motivation (g = 0.29; CI 95% [0.17, 0.41]) and identified regulation (g = 0.23; CI 95% [0.10, 0.35]) and a negative heterogeneous, small effect on external regulation (g = −0.16; CI 95% [-0.31, −0.00]) and amotivation (g = −0.14; CI 95% [-0.28, −0.01]). SDT-based instruction did not have an effect on integrated regulation (g = 0.08; CI 95% [-0.11, 0.28]) nor introjected regulation (g = 0.03; CI 95% [-0.7, 0.13]). Univariate categorical moderator analyses highlighted multiple variables that impacted the size of the effects on the outcomes, including type of intervention and control group, length of study, age of participants, and study quality. Findings from the moderator analyses challenge the practical implications of SDT-based instructional interventions in improving motivation in organized physical activity. High-quality experimental trials using careful and precise conceptualizations of need-supportive behaviors and strategies would benefit the discipline.
