Training but no Training

Polypectomy: No training, No cancer prevention!

1] showing the efficacy of polypectomy in preventing colorectal cancer (CRC) incidence and 2 subsequent prospective series showing the feasibility of colonoscopy as primary screening technique [2, 3], over 60 % of the American population and 10 % to 20 % of the European population have undergone colonoscopy for screening purposes [4, 5]. The strict association between the diagnostic performance...

OCR with No Shape Training

We present a document-specific OCR system and apply it to a corpus of faxed business letters. Unsupervised classification of the segmented character bitmaps on each page, using a “clump” metric, typically yields several hundred clusters with highly skewed populations. Letter identities are assigned to each cluster by maximizing matches with a lexicon of English words. We found that for 2/3 of t...

Attentional Filter Training but Not Memory Training Improves Decision-Making

Decision-making has a high practical relevance for daily performance. Its relation to other cognitive abilities such as executive control and memory is not fully understood. Here we asked whether training of either attentional filtering or memory storage would influence decision-making as indexed by repetitive assessments of the Iowa Gambling Task (IGT). The IGT was developed to assess and simu...

No Tranfer of Training in Simple Addition

Several researchers have proposed that skilled adults may solve single-digit addition problems (e.g. 3+1=4, 4+3=7) using a fast counting procedure. Practicing a procedure often leads to transfer of learning and faster performance of unpracticed items. Such transfer has been demonstrated using a counting-based alphabet arithmetic task (e.g., B+4 = C D E F) that indicated robust RT gains when unt...
