Gaze Behaviour

When watching an actor manipulate objects, observers, like the actor, naturally direct their gaze to each object as the hand approaches and typically maintain gaze on the object until the hand departs. Here, we probed the function of observers' eye movements, focusing on two possibilities: (i) that observers' gaze behaviour arises from processes involved in the prediction of the target object of the actor's reaching movement and (ii) that this gaze behaviour supports the evaluation of mechanical events that arise from interactions between the actor's hand and objects. Observers watched an actor reach for and lift one of two presented objects. The observers' task was either to predict the target object or judge its weight. Proactive gaze behaviour, similar to that seen in self-guided action–observation, was seen in the weight judgement task, which requires evaluating mechanical events associated with lifting, but not in the target prediction task. We submit that an important function of gaze behaviour in self-guided action observation is the evaluation of mechanical events associated with interactions between the hand and object. By comparing predicted and actual mechanical events, observers, like actors, can gain knowledge about the world, including information about objects they may subsequently act upon.

Is there a role for extraretinal factors in the maintenance of stability in a structured environment?

Perceptual Factors

The calibration solution to the stability of the world despite eye movements depends, according to Bridgeman et al., upon a combination of three factors which presumably all need to operate to achieve the goal of stability. Although the authors admit (sect. 4.3, para. 5) that the relative contributions of retinal and extraretinal factors will depend on the particular viewing situation, Figure 5 (sect. 4.3) makes it clear in its representation that the role of perceptual factors is relatively minor compared to extraretinal ones. It is with this representation that this commentary wishes to take issue, believing that it occurs as a result of some assumptions about terminology that may be ambiguous, as well as some misconceptions about the circumstances in which there is a need for stability.

scholarly journals Action predictability is reflected in beta power attenuation and predictive eye movements in adolescents with and without autism

Reduced Action

Most theoretical accounts of autism posit difficulties in predicting others’ actions, and this difficulty has been proposed to be at the root of autistic individuals’ social communication differences. Empirical results are mixed, however, with autistic individuals showing reduced action prediction in some studies but not in others. It has recently been proposed that this effect might be observed primarily when observed actions are less predictable, but this idea has yet to be tested. To assess the influence of predictability on neural and behavioural action prediction, the current study employed an action observation paradigm with multi-step actions that become gradually more predictable. Autistic and non-autistic adolescents showed similar patterns of motor system activation during observation, as seen in attenuated mu and beta power compared to baseline, with beta power further modulated by predictability in both groups. Bayesian statistics confirmed that action predictability influenced beta power similarly in both groups. The groups also made similar behavioural predictions, as seen in three eye-movement measures. We found no evidence that autistic adolescents responded differently than non-autistic adolescents to the predictability of an observed action. These findings show that autistic adolescents do spontaneously predict others’ actions, both neurally and behaviourally, which calls into question the role of action prediction as a key mechanism underlying autism.

Role Of Religion

One of the most important reasons for such a clearly distressed state of society was the decline of religion as a social force, the external manifestation of which is the weakening of religious institutions. "Religion," Baha'u'llah writes, "is the greatest of all means of establishing order in the world to the universal satisfaction of those who live in it." The weakening of the foundations of religion strengthened the ranks of ignoramuses, gave them impudence and arrogance. "I truly say that everything that belittles the supreme role of religion opens way for the revelry of maliciousness, inevitably leading to anarchy. " In another Tablet, He says: "Religion is a radiant light and an impregnable fortress that ensures the safety and well-being of the peoples of the world, for God-fearing induces man to adhere to the good and to reject all evil." Blink the light of religion, and chaos and distemper will set in, the radiance of justice, justice, tranquility and peace. "

An important problem of religious studies, the history of religion as a branch of knowledge is the periodization process of the development of religious phenomenon. It is precisely here, as in focus, that the question of the essence and meaning of the religious development of the human being of the world, the origin of beliefs and cult, the reasons for the changes in them, the place and role of religion in the social and spiritual process, etc., are converging.

Principal Subject

The paper is devoted to the role of the global financial market in the development of Russian big business. It proves that terms and standards posed by this market as well as opportunities it offers determine major changes in Russian big business in the last three years. The article examines why Russian companies go abroad to attract capital and provides data, which indicate the scope of this phenomenon. It stresses the effects of Russian big business’s interaction with the world capital market, including the modification of the principal subject of Russian big business from integrated business groups to companies and the changes in companies’ behavior: they gradually move away from the so-called Russian specifics and adopt global standards.

The article covers unified issues of the long-term strategy development, the role of science as well as democracy development in present-day Russia. The problems of budget proficit, the Stabilization Fund issues, implementation of the adopted national projects, an increasing role of regions in strengthening the integrity and prosperity of the country are analyzed. The author reveals that the protection of businessmen and citizens from the all-embracing power of bureaucrats is the crucial condition of democratization of the society. Global trends of the world development and expert functions of the Russian science are presented as well.

Role Of The Government

This paper analyzes the problem of technological backwardness of economy. In many mostly developing countries their economies use obsolete technologies. This can create the illusion that this or that business is prosperous. At the level of international competition, however, it is obvious that these types of firms do not have any chance for success. Retroeconomics as a theory of technological backwardness and its detrimental effect upon a country’s economy is considered in the paper. The role of the government is very important for overcoming the effects of retroeconomy. The phenomenon of retroeconomy is already quite deep-rooted throughout the world and it is essential to consolidate the attention of economists and politicians on this threat.
