A dual-route perspective on poor reading in a regular orthography: evidence from phonological and orthographic lexical decisions.
Cogn Neuropsychol. 2008 Jul;25(5):653-76
Authors: Bergmann J, Wimmer H
Impairments of the lexical and the nonlexical reading route were examined for German-speaking dyslexic readers by measuring accuracy and speed of phonological and orthographic lexical decisions. Different from English-based findings, we found little difficulty with the phonological distinction between pseudohomophones and nonwords, but a major difficulty with the orthographic distinction between words and pseudohomophones. Subtyping identified pure surface dyslexia cases but no case of pure phonological dyslexia. Dyslexic speed impairments were traced to three loci in the dual-route model: an impoverished orthographic lexicon, and slow access from orthographic to phonological lexicon entries (lexical route) and from graphemes to phonemes (nonlexical route). A review of distal cognitive deficits suggested that the orthographic lexicon is affected by phonological deficits and that the slow functioning of the lexical and the nonlexical route reflects a general visual-verbal speed impairment and not a purely visual-attentional deficit.

Different letter-processing strategies in diagnostic subgroups of developmental dyslexia.
Cogn Neuropsychol. 2008 Jul;25(5):730-44
Authors: Lachmann T, van Leeuwen C
Normally reading adults (N = 15) and primary school children (N = 24) and two diagnostic subgroups of children with developmental dyslexia (N = 21)-all native German speakers-performed a successive same-different task with pairs of letters and nonletters (pseudoletters or geometrical shapes). The first item of a pair was always presented on its own, and the second either on its own or surrounded by a congruent or incongruent nontarget shape. Adults showed congruence effects with nonletters but not with letters, and children with both types of stimuli. Frequent-word reading-impaired dyslexics (N = 11) in addition showed dramatically slower overall reaction times. Nonword reading-impaired dyslexics (N = 10) showed congruence effects with nonletters but negative congruence effects with letters. The results support the notion that normal readers have established a special visual processing strategy for letters. Processing speed rather than reading expertise seems crucial for this strategy to emerge. The contrasting effects between subgroups of dyslexics reveal specific underlying deficits.

This poem by Mary Oliver arrived in my email inbox today, appended to a notice from the Reference Department at Newark Public Library.Percy and Books (Eight), by Mary OliverPercy does not like it when I read a book.He puts his face over the top of it and moans.He rolls his eyes, sometimes he sneezes.The sun is up, he says, and the wind is down.The tide is out and the neighbor's dogs are playing.But Percy, I say, Ideas! The elegance of language!The insights, the funniness, the beautiful storiesthat rise and fall and turn into strength, or courage.Books? says Percy. I ate one once, and it was enough. Let's go.The poem is from Oliver's collection, Red Bird (2008)I didn't mean to post poems two days in a row on the blog, but ironically, modern technology pushed me into into the world of poetry. Yesterday, I took a digital camera on my lunchtime walk, thinking I would make images that were absolutely copyright free to post on the blog. Then I used Grangers' Poetry database to find poems about (keyword) "woods" and chose a suitable poem to post, illustrated by my picture of the swampy area behind the library. Today, the New Jersey librarians' listserv brought me the usual array of notices, salespitches from publishers and bibliophilic chatter, some useful, but taken as a whole, mostly causing a strong feeling of Email Overload. Was it a reward to me for diligently going through my entire inbox, that one email brought this terrific poem? Proving that new means of communication are not incompatible with the old. Or maybe proving the adage, it's an ill wind that blows no good - even a surfeit of digital hot air in your inbox can bring a hidden gem.PS: my Border Collie ate the dog obedience book that I borrowed from the first library I worked in.

Background:
Music perception and performance are comprehensive human cognitive functions and thus provide an excellent model system for studying human behaviour and brain function. However, the molecules involved in mediating music perception and performance are so far uncharacterised.
Objective:
To unravel the biological background of music perception, using molecular and statistical genetic approaches.
Methods: 15 Finnish multigenerational families (with a total of 234 family members) were recruited via a nationwide search. The phenotype of all family members was determined using three tests used in defining musical aptitude: a test for auditory structuring ability (Karma Music test; KMT) commonly used in Finland, and the Seashore pitch and time discrimination subtests (SP and ST respectively) used internationally. We calculated heritabilities and performed a genome-wide variance components-based linkage scan using genotype data for 1113 microsatellite markers.
Results:
The heritability estimates were 42% for KMT, 57% for SP, 21% for ST and 48% for the combined music test scores. Significant evidence of linkage was obtained on chromosome 4q22 (LOD 3.33) and suggestive evidence of linkage at 8q13-21 (LOD 2.29) with the combined music test scores, using variance component linkage analyses. The major contribution of the 4q22 locus was obtained for the KMT (LOD 2.91). Interestingly, a positive LOD score of 1.69 was shown at 18q, a region previously linked to dyslexia (DYX6) using combined music test scores.
Conclusion:
Our results show that there is a genetic contribution to musical aptitude that is likely to be regulated by several predisposing genes or variants. (Source: Journal of Medical Genetics)

Electronic waste, "e-waste" or "Waste Electrical and Electronic Equipment" ("WEEE") is a waste type consisting of any broken or unwanted electrical or electronic machine. Recyclable electronic waste is sometimes further categorize as a "commodity" while e-waste which cannot be reuse is distinguished as "waste". Both types of e-waste have raised concern allowing for that many components of such equipment are considered toxic and are not biodegradable. Respond to these concerns, many European countries banned e-waste from landfills in the 1990s.The European Union would further advance e-waste policy in Europe by realize the Waste Electrical and Electronic Equipment Directive in 2002 which holds manufacturers in charge for e-waste disposal at end-of-life. Similar legislation has been enact in Asia, with e-waste legislation in the United States limited to the state level due to delayed efforts in the United States Congress regarding multiple e-waste legislation bills.Due to the difficulty and cost of recycling used electronics as well as lackluster enforcement of legislation regarding e-waste exports, large amounts of used electronics have been sent to countries such as China, India, and Kenya, where inferior environmental standards and working conditions make processing e-waste more profitable.
