Impact of working memory capacity on predominance of parietal over frontal P300 amplitude
Brain Cogn. 2023 Jun 18;170:106056. doi: 10.1016/j.bandc.2023.106056. Online ahead of print.ABSTRACTWorking memory-related neural activity varies with task load, and these neural variations can be constrained by working memory capacity (WMC). For instance, some studies suggest that parietal and frontal P300 amplitudes, reflecting working memory functioning, vary differentially with task load and WMC. The present study explored whether the predominance of parietal over frontal P300 amplitude is related to WMC, and whether this relationship varies according to task load. Thirty-one adults aged 20-40 years performed a Sternbe...

Altered neural mechanisms of deception in individuals with autistic traits
Brain Cogn. 2023 Jun 13;170:106005. doi: 10.1016/j.bandc.2023.106005. Online ahead of print.ABSTRACTA successful deception involves making a decision, acting on it, and evaluating results. Here, we investigated deception in a non-clinical sample (n = 36) with varying autism traits using a coin-toss paradigm of active deception. The subjects were asked to react to the instructions by clicking one of the two boxes that could mislead their opponents, followed by feedback on their success or failure. During this reaction, their EEG activity was recorded, and the results suggested that people with high autistic traits exhibited...

Reliability of the P3 component in a 3-stimulus concealed information test with known and unknown stimuli
Brain Cogn. 2023 Jun 13;170:106004. doi: 10.1016/j.bandc.2023.106004. Online ahead of print.ABSTRACTThe parietal P3 amplitude of the event-related potential (ERP) has been highlighted to signal stimulus salience in concealed information tests (CITs) with known and unknown stimuli. To extend previous validity investigations in deception research, the reliability of the early parietal P3 amplitude in a 3-stimulus CIT including known and unknown stimuli has been investigated in a sample of N = 68 participants. Variations of Cronbach's Alpha and split-half reliability (odd-even, 1st vs. 2nd half) of the early parietal P3 ampli...

Interhemispheric transfer of visual information: Meaningfulness and response formation
We examined whether Redundancy Gain (RG) can be dissociated from the response stage of a go/nogo paradigm, and whether the meaningfulness of a stimulus modulates the stage at which interhemispheric transfer occurs. Experiment 1 used a lateralized match-to-category paradigm, taken from categories with varying meaningfulness. Experiment 2 presented a novel design, which separates the perceptual stage from response formation, in examination of RG. A sequence of two stimuli was presented. Participants responded by matching the category of the second stimulus to that of the first. The redundant stimulus could appear at the firs...
