SIGNAL-SOURCE SWITCHING IN HUMAN VIGILANCE

Effects of Signal Probability on Individual Differences in Vigilance

Decrements in the proportion of signals detected over time on task and large individual differences in performance are typical findings in studies of vigilance. This study investigates the effects of signal probability on individual differences in vigilance performance. Participants monitored stimulus events on computer displays over 2-h periods at three signal probability levels (.01, .04, & ....

Decision Interval and Signal Detectability in a Vigilance Task.

This paper discusses the effect ol the assumed decision interval on the measurement of d'. Previous experiments have revealed a decrement in the detectabdity (d') of signals during a particular vigilance task involving the detection of a brief pause in the movement of a clock hand. In order to measure the false alarm probability, Ss were required to make a decision once every five sec. as to wh...

EEG Based Brain Signal Detection for Determining Vigilance Level

Abstract: The key work of the project is analyzing the brain signals. Human brain consists of millions of interconnected neurons. This neuron pattern will change according to the human thoughts. At each pattern formation unique electric brain signal will form. In This project we are going to use ARM LPC2148 controller,we are using brainwave sensor to collect the different types of waves generat...
