Effects of alcohol intoxication on risk-taking, strategy and error rate in visuomotor performance

Article Abstract:

Adult men (N = 44) participated for 2 days (alcohol vs. placebo treatment) in a double-blind crossover experiment. Performance on the Digit Symbol Substitution Task (DSST) and a visuomotor (VM) task was measured 4 times each day. On the alcohol-treatment day, data were obtained once during ascending breath alcohol levels (BALs), once during maximal BALs (0.05 or 0.10), and twice during descending BALs. Data were collected at the same time points on the placebo-treatment day. Limited evidence for acute tolerance was obtained with the DSST, but error rates on the VM task were higher during maximal and descending BALs. Error rates remained near placebo values, and participants displayed slightly greater caution, while BALs were ascending. Strategy scores on the VM task exceeded placebo scores during maximal intoxification. Data interpretation is focused on individuals in higher level (e.g., professional) position.

Sign and sound

Article Abstract:

The characteristics of the Japanese language and the mechanics of creating written words and sentences is explained. The challenge of creating word processing equipment and software that can handle this complex character-language is illustrated with sample words and how they are made. The inclusion of learning capabilities in Japanese word processors has reduced the amount of post-editing that was once required.

Cover boy: Chip Kidd has brought an edge to the serene dust jacket

Article Abstract:

Kidd, employed at Alfred A. Knopf for 10 years, has designed over 600 book covers. Currently a book of his own is being published, and a museum exhibition of his work has opened. His first idea for a cover does not alway satisfy him. Four designs for 'Air Frame' were discarded before the fifth was accepted.
