Numerical error checking.

2 questions were raised about numerical error checking: "(a) What is the effect of grouping digits on the speed and accuracy of error checking? (b) How does the probability of error affect the speed and accuracy of error checking?" Volunteer college students (34) checked numbers on 1 page against numbers on another page. "… speed of checking varied greatly with size of horizontal group." "… the number of errors remaining undetected is directly related to the original number of errors." "The speed of error checking was highest for groupings of three or four digits." (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Operant therapy for excessive checking.

Evaluated a specific therapeutic approach to the treatment of excessive checking things behavior (obsessive compulsive disorder). S was an 18-yr-old high school graduate who had failed to respond to traditional therapy. The strategy was to integrate inconvenient consequences as a part of S's self-control behavior and to delay the occurrence of the deviant behavior. When to increase the intensity of inconvenient consequences to produce a facilitation of the weakening process is discussed. A follow-up study indicates that the present approach is clinically effective. (French summary) (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Are young adults checking their skin for melanoma?

This study examined the prevalence and predictors of self screening for melanoma in a large sample of young New Zealanders. A self-report questionnaire was administered to a sample of 909, 21-year-olds to investigate if young adults check their skin for changes in lesions which could be melanoma, and to identify the factors which influence this behaviour and any subsequent help seeking. Fifty-three per cent reported checking their skin in the past year, with 20% noticing a change in a mole or freckle. Forty-five per cent of those who noticed a change sought medical advice. The most common reason for not seeking advice was cost. Women were more likely that men to have checked their skin, to have noticed a change and to have sought medical advice. In addition to gender, tendency to self check was also associated with knowledge of melanoma and perceived risk of melanoma. These results are discussed in light of the current debate regarding skin cancer screening. This study fills a gap in the literature regarding self screening for melanoma in young adults and identifies ways in which future prevention campaigns might be modified to address the concerns of this age group.

The footprint: a method for checking femoral tunnel placement

Anterior placement of the femoral tunnel during anterior cruciate ligament reconstruction results in nonisometric placement, and posterior placement can lead to posterior tunnel blow out or troughing. Creating a pretunnel footprint before final placement and drilling allows the surgeon to visually verify that proper femoral tunnel placement has been obtained.
