Introduction

Mind wandering, in which cognitive processing of the external environment decreases in favor of internal processing (Smallwood & Schooler, 2006), has been consistently associated with errors on tasks requiring sustained attention and continuous stimulus monitoring (e.g., Cheyne, Carriere, & Smilek, 2006; Robertson, Manly, Andrade, Baddeley, & Yiend, 1997; Smallwood et al., 2004). Consistent with this finding, recent neuroimaging studies suggest that mind wandering engages the default neural network (Christoff, Gordon, Smallwood, Smith, & Schooler, 2009; Mason et al., 2007; Smallwood, Beach, Schooler, & Handy, 2008; Weissman, Roberts, Visscher, & Woldorff, 2006) and is associated with decreased neural analysis of incoming information (Christoff et al., 2009; Smallwood, Beach et al., 2008; Weissman et al., 2006). Here we propose that mind wandering also involves overt embodied components whereby external input is blocked at the sensory endings. We demonstrate that during an extended period of reading, episodes of mind wandering, compared with on-task periods, contain more eye closures (blinks) and fewer fixations on the text? even as subjects continue to scan the text.

The residual effects of the Enron (ENE) debacle are slowly, but surely, beginning to PERMEATE the investment landscape. In many instances it is hard to know whether the secondary problems are critically severe, or just a case of paranoid investors overreacting to ghosts. In 1997, ENE was a rather ordinary gas distribution company trading at $20/share. In the 1998-2000 period, the stock rocketed to nearly $85/share, because of celebrious views about their on-line commodity trading capabilities, an 18,000-mile fiber-optic cable and ultimately, the perceived 'rewards' from the California electricity crisis. Management gradually succumbed to the temptation to artificially inflate earnings with artful 'financial engineering' techniques and, all the while, they piled up debt and preferred...

-The last day for suspicious trading on American and United Airlines. Today, three years ago, the Chicago Exchange sees the purchase of 4,516 put options on American to only 748 call - 60 times above normal. On the Pacific Exchange, the trading ratio on United is 25 times greater than normal. Later, investigators can't help but notice that no other airlines saw such trading in their put options. Analyst John Kinnucanone, quoted by the San Francisco Chronicle, said "I saw put-call numbers higher than I've ever seen in 10 years of following the markets, particularly the options market."
-The last day for suspicious trading on Morgan Stanley, one of the World Trade Center's largest tenants. Between Sept. 7 and Sept. 10, the company experiences an increase of 27 times in the purchase...
