The distractive effects on attentional task performance in different paradigms are analyzed in this paper. I demonstrate how distractors may negatively affect (interference effect), positively (redundancy effect) or neutrally (null effect). Distractor effects described in literature are classified in accordance with their hypothetical source. The general rule of the theory is also introduced. It contains the formal prediction of the particular distractor effect, based on entropy and redundancy measures from the mathematical theory of communication (Shannon, 1948). Single- vs dual-process frameworks are considered for hypothetical mechanisms which underpin the distractor effects. Distractor profiles (DPs) are also introduced for the formalization and simple visualization of experimental data concerning the distractor effects. Typical shapes of DPs and their interpretations are discussed with examples from three frequently cited experiments. Finally, the paper introduces hierarchical hypothesis that states the level-fashion modulating interrelations between distractor effects of different classes.
This chapter consists of two parts. The first one presents a summary of the selfdetermination theory account of people’s good living and optimal functioning. It highlights three motivational components identified by this theory: psychological needs (needs for autonomy competence and relatedness), aspirations and life strivings, and the continuum of motivational regulation. All these components are considered in relation to people’s eudaimonic happiness and optimal, healthy functioning. The main conclusion of this section is that in order to be happy, people need to regularly and in a balanced way gratify their needs, have strong intrinsic strivings relative to extrinsic aspirations, and be relatively self-determined in their main domains of living and functioning. The second part addresses in more detail the controversial question of the nature of human autonomy as a fundamental condition for people’s thriving and flourishing. It provides a conceptual analysis of this construct, uncovers the mechanisms of its beneficial performance, and addresses a highly discussed question of relationships of autonomy and culture. This section ends with a conclusion on the fundamental importance of human autonomy for people, communities and societies to survive and thrive.
The results of research of different areas of personality of homeless men: values, life attitudes, activity, homelessness area is presents. The data indicate the presence of a number of characteristics inherent in varying degrees all homeless people. The data obtained can be used to build an effective program of psychological re-socialization of homeless people.
In 2006, Russia amended its competition law and added the concepts of ‘collective dominance’ and its abuse. This was seen as an attempt to address the common problem of ‘conscious parallelism’ among firms in concentrated industries. Critics feared that the enforcement of this provision would become tantamount to government regulation of prices. In this paper we examine the enforcement experience to date, looking especially closely at sanctions imposed on firms in the oil industry. Some difficulties and complications experienced in enforcement are analysed, and some alternative strategies for addressing anticompetitive behaviour in concentrated industries discussed.
