Wandering spleen is a rare condition, characterized by a mobile spleen that is attached only by an elongated vascular pedicle, allowing it to migrate to any part of the abdomen or pelvis. Mesenteroaxial gastric volvulus usually occurs in children and may be associated with wandering spleen. Both entities result from abnormal laxity or absence of the peritoneal attachments due to abnormal fusion...

Given the negative effects of mind wandering on performance, it may be profitable to be aware of task-unrelated thoughts (TUTs) as they occur. The present study investigated whether motivating people to catch TUTs increases meta-awareness. We offered incentives for increased self-catching during reading. To enhance the veracity of these self-reports, we used a "bogus-pipeline" procedure; we con...

This paper reports a wandering weekday effect: the pattern of day seasonality in stock market returns is not fixed, as assumed in the Monday or weekend effects, but changes over time. Analysing daily closing prices in eleven major stock markets during 1993–2007, our results show that the wandering weekday is not conditional on average returns in the previous week (the ‘‘twist” in the Monday eff...

Let K be a number field, let φ(x) ∈ K(x) be a rational function of degree d > 1, and let α ∈ K be a wandering point such that φ(α) = 0 for all n > 0. We prove that if the abc-conjecture holds for K, then for all but finitely many positive integers n, there is a prime p of K such that vp(φ (α)) > 0 and vp(φ (α)) 0 for all positive integers m < n. Under appropriate ramification hypotheses, we can...

The mind wanders, even when people are attempting to make complex decisions. We suggest that such mind wandering—allowing one’s thoughts to wander until the “correct” choice comes to mind—can positively impact people’s feelings about their decisions. We compare post-choice satisfaction from choices made by mind wandering to reasonbased choices and randomly assigned outcomes. Participants chose ...

In this Comment, we contrast different conceptions of mind wandering that were presented in two recent theoretical reviews: Smallwood and Schooler’s (2006) The Restless Mind and Watkins’s (2008) Constructive and Unconstructive Repetitive Thought. We also introduce a new perspective on the role of executive control in mind wandering by integrating empirical evidence presented in Smallwood and Sc...

The acute torsion of wandering spleen is a very rare disease characterized by acute abdominal pain. Without early surgical intervention, wandering spleen can lead to splenic infarction or rupture. However, early clinical diagnosis is very difficult, so imaging modalities play an important role. We present a case of acute abdominal pain due to torsion of the wandering spleen in a 17-year-old gir...

Studies have suggested that the default mode network is active during mind wandering, which is often experienced intermittently during sustained attention tasks. Conversely, an anticorrelated task-positive network is thought to subserve various forms of attentional processing. Understanding how these two systems work together is central for understanding many forms of optimal and sub-optimal ta...

Wandering spleen is a rare cause of acute abdomen. Generally, it remains asymptomatic, it may present clinically as a painless mobile mass or rarely as an acute abdomen when the wandering spleen twists on its pedicle, resulting in splenic congestion, infarction with or without involvement of neighbouring visceras. Here, we present an unusual case of torsion of a wandering spleen, which resulted...

Background: Attention deficit hyperactivity disorder (ADHD) is one of the most common neurodevelopmental disorders in school-aged children. Objectives: This study assessed effectiveness metacognitive therapy behavioral-emotional problems, cognitive-emotional regulation strategies, and mind wandering children with ADHD. Methods: quasi-experimental utilized a pretest-posttest design control group...
