Do animacy effects persist in memory for context?
2017
International audience; The adaptive view of human memory (Nairne, 2010) assumes that animates (e.g., rabbit) are remembered better than inanimates (e.g., glass) because animates are ultimately more important for fitness than inanimates. Previous studies provided evidence for this view by showing that animates were recalled or recognized better than inanimates (e.g., Nairne, VanArsdall, Pandeirada, Cogdill, & LeBreton, 2013), but they did not assess memory for contextual details (e.g., where animates vs. inanimates occurred). In this study, we tested recollection of spatial information (Study 1) and temporal information (Study 2) associated with animate versus inanimate words. The findings …
Too many passwords? : How understanding our memory can increase password memorability
2018
Passwords are the most common authentication mechanism, that are only increasing with time. Previous research suggests that users cannot remember multiple passwords. Therefore, users adopt insecure password practices, such as password reuse in response to their perceived memory limitations. The critical question not currently examined is whether users’ memory capabilities for password recall are actually related to having a poor memory. This issue is imperative: if insecure password practices result from having a poor memory, then future password research and practice should focus on increasing the memorability of passwords. If, on the other hand, the problem is not solely related to memory…
Do healthy elders, like young adults, remember animates better than inanimates? An adaptive view
2016
International audience; Background/Study Context: It has been found that young adults remember animates better than inanimates. According to the adaptive view of human memory, this is due to the fact that animates are more important for fitness purposes than inanimates. This effect has been ascribed to episodic memory, where older people exhibit difficulties. Methods: Here the authors investigated whether the animacy effect in memory also occurs for healthy older adults. Older and young adults categorized words for their animacy characteristics and were then given an unexpected recognition test on the words using the Remember/Know paradigm. Executive functions were also evaluated using seve…

Functional Signatures of Human CD4 and CD8 T Cell Responses to Mycobacterium tuberculosis
2014
With 1.4 million deaths and 8.7 million new cases in 2011, tuberculosis (TB) remains a global health care problem and together with HIV and Malaria represents one of the three infectious diseases world-wide. Control of the global TB epidemic has been impaired by the lack of an effective vaccine, by the emergence of drug-resistant forms of Mycobacterium tuberculosis (Mtb) and by the lack of sensitive and rapid diagnostics. It is estimated, by epidemiological reports, that one third of the world's population is latently infected with Mtb, but the majority of infected individuals develop long-lived protective immunity, which controls and contains Mtb in a T cell-dependent manner. Development o…
Problems of coding stereo images in human memory
2010
This paper discusses the memorization and recall by man of a sequence of planar or stereoscopic images, including six frames that contain a planar strip (8×8 positions of the stimulus) or a volume strip (8×4×2 positions). At the recall stage, the subject chose between the stimulus and three distractors in each frame. It is shown that the times for recognition and recall are less for volume stimuli, while the percent of correct responses is greater for planar stimuli. For volume stimuli, the distribution of errors depends on the disparity between the target and the selected distractor. A model based on a heteroassociative neural network reproduces the error distribution for planar but not fo…
