Electrodermal habituation speed and visual monitoring performance.
1984
Previous research has suggested that speed of habituation of the electrodermal orienting response is related to auditory vigilance performance. The present study investigated the relationship between habituation speed, nonspecific response frequency, and detection performance in a complex visual monitoring task. Two levels of task difficulty were employed. In the visual monitoring task, correct detections declined across blocks, and fewer signals were detected in the difficult task condition. Slow habituators detected more signals than fast habituators, but NSR-frequency was not significantly related to the number of correct detections. The implications of these findings for different model…
Leonid fluxes: 1994-1998 activity patterns
2001
Abstract-The Leonid meteor shower was observed worldwide in 1998 November in an intensive campaign without precedent. During this international effort -35 500 meteors were reported by members and collaborators of the International Meteor Organization (IMO) using a standard methodology. Despite the absence of a meteor storm in 1998, the rich observational data allow us to obtain a detailed unprecedented knowledge of the stream structure between 1994 and 1998. INTRODUCTION We present here the results from long-term visual monitoring by members and collaborators of the International Meteor Organization (IMO) and photographic and charge-coupled device (CCD) monitoring research obtained by membe…
