This study examined the effects of employee self-enhancement motives on job performance behaviors (organizational citizenship behaviors and task performance) and the value of these behaviors to them. The authors propose that employees display job performance behaviors in part to enhance their self-image, especially when their role is not clearly defined. They further argue that the effects of t...

Task-partitioning refers to the process whereby a task is divided into two or more sub-tasks. Through task partitioning both efficiency and effectiveness can be improved provided the right environmental conditions. We synthesize self-organized task partitioning behaviors for a swarm of mobile robots using artificial evolution. Through validation experiments, we show that the synthesized behavio...

Differences in infant distress and regulatory behaviors based on the quality of attachment to mother, emotion context (frustration versus fear), and whether or not mothers were actively involved in the emotion-eliciting tasks were examined in a sample of 98 16-month-old infants and their mothers. Dyads participated in the Strange Situation, a limiting task designed to elicit infant frustration,...

Facial behaviors represent activities of face or facial feature in spatial or temporal space, such as facial expressions, face pose, gaze, and furrow happenings. An automated system for facial behavior recognition is always desirable. However, it is a challenging task due to the richness and ambiguity in daily facial behaviors. This paper presents an efficient approach to real-world facial beha...

[email protected]; [email protected]; [email protected]; [email protected] ABSTRACT In this paper, we propose to personalize search result content through modeling multiple user behavioral measures in different ways as evidence for implicit relevance feedback for different types of search tasks. The point of this personalization is to predict potentially useful documents based on the t...

Patients with alien hand (AH) syndrome from medial frontal lesions exhibit involuntary but seemingly purposeful contralesional upper limb movements. Two observations about AH patients have received little, if any, experimental confirmation. The first is that AH is triggered opportunistically by nearby objects. The second is that AH behaviors are increased in conditions of fatigue or anxiety, i....

ION LEVEL OF MESSAGE Abstraction level was analyzed as a function of task interdependence and valence of target’s behavior. Both were between-participants variables. The predicted two-way interaction was significant, F(1, 43) = 9.58, p < .005 (see Table 1). As expected, negative target behaviors were described more abstractly in the competition condition (M = 2.40) than the cooperation conditio...
