A Novel Framework for Unconscious Processing
Understanding the distinction between conscious and unconscious cognition remains a priority in psychology and neuroscience. A comprehensive neurocognitive account of conscious awareness will not be possible without a ... -
Classification of Overt and Covert Speech for Near-Infrared Spectroscopy-Based Brain Computer Interface
Kamavuako, Ernest Nlandu; Sheikh, Usman Ayub; Gilani, Syed Omer; Jamil, Mohsin; Niazi, Imran Khan (Sensors, 2018)People suffering from neuromuscular disorders such as locked-in syndrome (LIS) are left in a paralyzed state with preserved awareness and cognition. In this study, it was hypothesized that changes in local hemodynamic ... -
Decoding and encoding models reveal the role of mental simulation in the brain representation of meaning
Soto, David; Sheikh, Usman Ayub; Mei, Ning; Santana Hermida, Roberto
(Royal Society Open Science, 2020)
How the brain representation of conceptual knowledge varies as a function of processing goals, strategies and task-factors remains a key unresolved question in cognitive neuroscience. In the present functional magnetic ... -
Decoding the Meaning of Unconsciously Processed Words Using fMRI-based MVPA
Does the human brain elicit patterns of activity associated with the meaning of words in the absence of conscious awareness? Do such non-conscious semantic representations generalize across languages? This study aimed to ... -
Neurocognitive mechanisms supporting the generalization of concepts across languages
The neurocognitive mechanisms that support the generalization of semantic representations across different languages remain to be determined. Current psycholinguistic models propose that semantic representations are likely ...
