1. Respiration and Body Temperature as Measures of Sustained Attention: an Empirical Evidence Gaurav Kumar Rai and Indramani L. Singh Cognitive Science Laboratory Department of Psychology Banaras Hindu University, Varanasi-221005 Email ID: gauravcl@gmail.com, ilsingh_bhu@rediffmail.com

2. Vigilance A state of readiness to detect and respond to a small changes occurring at random time intervals over prolonged periods. Impairment in 20-35 min. Performance ? Timeperiod Cognitive Science Laboratory, BHU

3. Determinant of Vigilance Performance Vigilance Performance Cognitive Science Laboratory, BHU

4. Vigilance Performance Measure Existing approaches do not enable a direct assessment of vigilance. Available measures provide information about a specific state of the operator like stress, fatigue mental workload etc. on the basis of :- Behavioral performance. Physiological Status. Subjective Quarry. Cognitive Science Laboratory, BHU

5. Performance Measure Reaction Time: elapsed time between the presentation of a sensory stimulus and the subsequent behavioral response. Accuracy (Hit rates): number of correct detection or response on given task. Cognitive Science Laboratory, BHU

6. Physiological Measure Body Temperature:The degree of hotness or coldness of a body part. Respiration:The number of breaths a person takes per minute. Cognitive Science Laboratory, BHU

7. Vigilance Task Type Sensory tasks, critical signals for detections at specified changes in the physical attributes of stimuli. Cognitive task, the signals that involves numerical, linguistic or semantic discrimination. a k X E w Cognitive Science Laboratory, BHU

20. Task: (F (1, 58) =31.44; p<.0001, eta2=.351)Interaction effects was also found significant (F (3, 174)=5.36; p<.001, eta2=.085) Cognitive Science Laboratory, BHU

22. Task: (F (1, 58)=7.20; p<.009, eta2=.110)Interaction effects was also found significant (F (3, 174)=8.15; p<.0001, eta2=.123) Cognitive Science Laboratory, BHU

25. Output Sensory vigilance task is more demanding than cognitive vigilance task. Respiration and Body Temperature decreases during vigilance task. There was not effect of vigilance ‘task type’ on respiration and body temperature. It can be concluded that respiration and body temperature are a sensitive measure but not have a sufficient level of diagnosticity. Cognitive Science Laboratory, BHU
