Cogstate Brief Battery: Cognition and the feigning of cognitive impairment in chronic pain.

Chronic pain (CP) is often associated with cognitive impairment. The Cogstate Brief Battery (CBB), a computerized assessment battery, has been studied in several neuropsychiatric disorders but not in CP. Since feigning of cognitive impairment is common in CP, the current study aimed to assess the CBB's utility in differentiating CP patients ( = 64) from healthy participants ( = 33), as well as to assess the effect of simulating cognitive impairment by CP patients on performance in the battery.

Establishing supplementary response time validity indicators in the Word Memory Test (WMT) and directions for future research.

Response time (RT) measures in the Word Memory Test (WMT) offer to complement information derived from conventional accuracy measures. The current study aimed to validate the findings of Lupu, Elbaum, Wagner, and Braw in which RT variability was assessed, for the first time, in the WMT. A secondary aim was to suggest directions for the future research of RT measures in Forced-Choice Recognition Memory Performance Validity Tests (FCRM-PVTs).

Eye tracking as a mean to detect feigned cognitive impairment in the word memory test.

Eye movements showed initial promise for the detection of deception and may be harder to consciously manipulate than conventional accuracy measures. Therefore, we integrated an eye-tracker with the Word Memory Test (WMT) and tested its usefulness for the detection of feigned cognitive impairment. As part of the study, simulators ( = 44) and honest controls ( = 41) performed WMT's immediate-recognition (IR) subtest while their eye movements were recorded.
