This study is concerned with the role that achievement goals may play in facilitating the psychological well-being of students. Specifically, we build on "goal theory" analysis of adaptive behavior in examining the relationship between task and ego goals, perceptions of school emphases on task and ego goals, and indices of well-being and disruptive behavior. Generally, task goals and perception...

In achievement contexts such as sport, achievement goal theory assumes that an individual's major concern is to demonstrate competence. However, competence may be expressed in two ways: as task and ego involvement (Nicholls, 1989). Seventy-eight boys (M age = 13.6 years) performed five climbing courses, and the influence of achievement goals, perceived ability, and task difficulty on effort and...

Language holds a unique position among the functions of the ego because its development and operation depend upon the synthesis of mental schematization, motor control, affective responses, and environmental stimulation. Moreover, language is a structural organization like the ego itself, and may be studied effectively through the vehicle of speech. Thus, it may be said that speech offers a win...

The current study examines the relationship between narcissism and aggression. The link between narcissistic personalities and heightened aggressive response to ego threat has been substantiated in the literature (Twenge & Campbell, 2003), but it is unclear whether this response is driven by a self-repairing mechanism to restore damaged self-esteem or by an ego-promoting mechanism to vent frust...

All the defensive measures of the ego against the id are carried out silently and invisibly. The most we can ever do is reconstruct them in retrospect: we can never really witness them in operation. … definite indications of obsessional exaggeration suggest that it is of the nature of reaction and that it conceals a long-standing conflict. Here again, observation of the particular mode of defen...

Maltreatment was predicted to negatively affect children's academic and behavioral adjustment through the creation of deficits in academic engagement, social competencies, ego resiliency, and ego control. Teachers' comprehensive evaluations, school records, and camp counselors' ratings were obtained for 229 socioeconomically disadvantaged children (ages 5-12 years), 146 of whom had been maltrea...

The purpose of this study was to analyse from the perspective of the achievement goal theory and the self-determination theory some variables which could help to promote positive motivation and to improve dispositional flow in adolescent athletes. A sample of 413 young athletes (from 12 to 16 years of age) completed the Perceived Motivational Climate in Sport Questionnaire-2, Perception of Succ...

Conventional particle filtering-based visual ego-motion estimation often suffers from large local linearization errors in the case of abrupt camera motion. The main contribution of this paper is to present a novel particle filteringbased visual ego-motion estimation algorithm that is especially robust to the abrupt camera motion. The robustness to the abrupt camera motion is achieved by multi-l...
