 | The objective of this project is to test whether the beta-adrenergic blocker propranolol, given following combat memory reactivation, results in a significantly greater weakening of traumatic memories than propranolol alone, supporting the proposition that this weakening is due to pharmacological blockade of memory reconsolidation, rather than nonspecific actions of propranolol. We hypothesize that subjects who undergo script preparation for the combat event(s) that caused their PTSD, followed by (post-reactivation) propranolol, ... |

| We conducted a study to address three research objectives: (1) to determine how the use of a specific aided target recognition (AiTR) system affected scout workload, stress, and performance; (2) to examine Soldier-system interface issues; (3) to determine tactics, techniques, and procedures (TTPs) for using AiTR. We found that overall workload, stress, and performance with AiTR were acceptable, although subject matter expert ratings of scout performance may have been lenient ... |

| The primary purpose of this project was to investigate the underlying principles for the future development of systems capable of estimating the cognitive state of an operator, the demands of the task, and the relevant environmental conditions. The cognitive state is estimated using physiological as well as behavioral measures. Examples of the physiological measures include EEG, heart rate, plethysmography, and galvanic skin response. The behavioral measures include performance on the ... |

| The Defense Advanced Research Projects Agency (DARPA) Augmented Cognition program is developing innovative technologies that will transform person-machine interaction by making information systems sensitive to the capabilities and limitations of the human component of the person-machine system. By taking better advantage of individual human capabilities, and being sensitive to human limitations, it is expected that an order of magnitude improvement in system performance can be achieved.

| Anecdotal evidence suggested that signals recorded using computerized polygraph instruments with the galvanic skin response (GSR) channel set in the manual mode are substantially different from those recorded with the instrument set in the automatic mode. This had been difficult to confirm since equipment was not available that would generate continuously variable resistance signals of known shape, magnitude, and frequency. Such a device was conceptualized, designed, constructed, tested, and aligned ... |

| Misinformation effects occur in laboratory settings despite disagreement over the mechanism(s) responsible for such effects. Both memory impairment and non-impairment hypotheses explain the phenomenon. The effects of misinformation were examined using the Concealed Knowledge Test (CKT), a psychophysiological detection of deception technique.

| This was an exploratory study designed to assess the effect of self- referent stimuli on the P300 component of the electroencephalogram (EEG). The stimuli were self-referent phrases. Self-referent phrases are phrases that are personally descriptive, and are, therefore, considered to be personally relevant. Personal relevance was manipulated through the truthfulness of the self-referent phrases. The EEG was examined for the occurrence of the P300 wave of the human event-related brain ... |

| Investigations into corona-discharge photography show that subjects placed in a high-voltage field exhibit corona that may be recorded photographically. The corona formation and structure depend on the applied field strength and gradient, the type of film used and the waveform and the pulse repetition rate of the applied voltage. Specimen properties affecting corona formation include resistivity, geometry, and moisture content; other factors may also be important. The discharge mechanism is ... |

| A delayed conditioning paradigm was employed to condition the stapedius muscle. While previous attempts have failed using loud sound as the unconditioned stimulus, the paper presents evidence of successful conditioning of this muscle when the unconditioned stimulus was a mild electrocutaneous stimulation of the external ear canal. Using a weak tone as the conditioned stimulus, conditioned responses were readily obtained in eight of ten subjects after only 30 or fewer ... |

| Galvanic skin resistance, arteria radialis pulse and blood pressure, respiration, and stomach motility were recorded electromechanically in man after olfactory stimulation. In most cases, skin resistance decreases rapidly and returns gradually to its original value frequently with temporary decrements in between. Arteria radialis pressure often shows a decrease, followed by a wavy pattern of alternate increments and decrements, before returning to its original value. Pulse frequency and amplitude are hardly ... |
