Relative debugging is a technique that addresses the problem of debugging programs developed using evolutionary software techniques. Recent developments allow relative debugging to be used on programs that have been ported from serial to parallel architectures. Such programs may change significantly in the porting process, and this raises many issues for the debugging process, such as how the a...

We investigated whether attention could be modulated through the implicit learning of temporal information in a rapid serial visual presentation (RSVP) task. Participants identified two target letters among numeral distractors. The stimulus-onset asynchrony immediately following the first target (SOA1) varied at three levels (70, 98, and 126 ms) randomly between trials or fixed within blocks of...

This index covers all technical items — papers, correspondence, reviews, etc. — that appeared in this periodical during 2003, and items from previous years that were commented upon or corrected in 2003. Departments and other items may also be covered if they have been judged to have archival value. The Author Index contains the primary entry for each item, listed under the first author's name. ...

In speech, the phenomenon of coarticulation (differentiation of phoneme production depending on the preceding or following phonemes) suggests an organization of movement sequences that is not strictly serial. In the skeletal motor system, however, evidence for comparable fluency has been lacking. Thus the present study was designed to quantify coarticulation in the hand movement sequences of si...

priorities permit. The comments should not exceed 350 words in length, with a maximum of five references; one figure or table can be printed. Exceptions may occur under particular circumstances. Contributions may include comments on articles published in this periodical, or they may be reports of unique educational character. Please include a cover letter with a complete list of authors (includ...

A rapid serial visual presentation technique was used to display sequentially two targets, T1 and T2, and monitor P3 amplitude and latency variations associated with the attentional blink (AB) effect. A red T1 digit was embedded on each trial in a sequence of black letters. T2 was either masked by a trailing stimulus or not masked. T1 had to be identified on a proportion of trials, or ignored i...

In general cognitive systems are comprised of more than a single subprocess. The arrangement and linkages of these subprocesses are known as “mental architecture”. The simplest non-trivial systems or manner of carrying out multi-tasking on discrete items is found in two diametrically opposite models that have been classically used to describe the architecture of this processing. Serial systems ...

Spelling deficits have repeatedly been observed in children with dyslexia. However, the few studies addressing this issue in dyslexic adults have reported contradictory results. We investigated whether Spanish dyslexics show spelling deficits in adulthood and which components of the writing production process might be impaired in developmental dyslexia. In order to evaluate the involvement of t...

A radiobiologically based 3D model of normal tissue has been developed in which complications are generated when 'irradiated'. The aim is to provide insight into the connection between dose-distribution characteristics, different organ architectures and complication rates beyond that obtainable with simple DVH-based analytical NTCP models. In this model the organ consists of a large number of f...

The simulation of computer architecture is an important task in the development of new architectures. Exploring novel architectures requires simulations which are flexible, easy to produce, and high performance. The greater these characteristics, the more efficiently the design space can be explored. A number of simulation frameworks exist which can assist the architect in creating new simulato...
