Recent commentaries have proposed conceptualizations of rumination in terms of both cognitive and behavioral avoidance. This study examined the relationship between rumination, avoidance and depression using a newly developed self-report measure of avoidance in depression, the Cognitive-Behavioral Avoidance Scale (CBAS) [Ottenbreit, N.D., & Dobson, K.S. (2004). Avoidance and depression: The con...

introduction: many factors are related to the disability of subjects with chronic low back pain. fear-avoidance of injury and movement are the most important risk factors to increase the disability followed by decreased physical activity in these patients. the aim of current study was to compare the level of disability and fear-avoidance between two groups of low back pain patients with and wit...

This paper treats taxation in kind (IKT) as an example of price regulation, emphasizing IKT-avoidance behavior, and its interactions with the other costs of price controls. This emphasis fundamentally changes efficiency conclusions, and adds new ones. IKTs do not in fact randomly sample suppliers, and the burdens of IKTs are not limited to the hidden tax paid by suppliers that actually transact...

In this study, we investigated to what extent indirect measures predict behavioural and physiological fear responses towards spiders. Implicit attitudes towards spiders were assessed using an implicit association test and attentional bias towards spiders was assessed using a dot probe task and a disengagement task. Results showed that a self report measure of fear for spiders, but not the indir...

Remote labs are increasingly being used as an effective tool for letting students practicing with real experiments, with limited effort and cost. A multi-robot setup, based on the LEGOMindstorms technology and the Matlab environment, allowing students to experiment with real robots through the Internet, has been developed. In this paper, a novel feature of this setup is presented. The concept o...

In this paper, we present a novel methodology to perform collective transport in the presence of obstacles. Three robots are physically connected in a semicircle around an object to be transported from a start to a goal location. The task poses two main challenges. First, the presence of both a goal and obstacles requires appropriate negotiation of the direction among the members of the group. ...

This paper presents WOAH, a method for real-time mobile robot path following and obstacle avoidance. WOAH provides reactive speed and turn instructions based on obstacle information sensed by a laser range finder. Unlike many previous techniques, this method allows a robot to move quickly past obstacles that are not directly in its path, avoiding slowdowns in path following encountered by previ...

An important pathway by which relationships influence health may involve how people cope with interpersonal tensions. This study examined whether same day and prior day avoidance and engagement in arguments are differentially associated with self-reported well-being (emotional, physical) and diurnal cortisol patterns. Participants from Wave 2 of the National Study of Daily Experiences (NSDE; N ...

The most widely used measures of avoidance strategies following stressful or traumatic experiences are unidimensional. However, recent work has emphasised the multifactorial nature of avoidance. One intriguing and as yet unexplored distinction is that between attempts at avoidance and successful avoidance. Two studies are reported with the aim of investigating the differential relationships bet...

Approach-avoidance paradigms create a competition between appetitive and aversive contingencies and are widely used in nonhuman research on anxiety. Here, we examined how instructions about threat and avoidance impact control by competing contingencies over human approach-avoidance behavior. Additionally, Experiment 1 examined the effects of threat magnitude (money loss amount) and avoidance co...
