The interaction effect between dopamine and task difficulty: Spontaneous eye blink rates diversely relate with Nogo-N2 across various task difficulties
Publication date: Available online 27 January 2020Source: International Journal of PsychophysiologyAuthor(s): Ting Zhang, Lurong Yu, Xianzhong HanAbstractNogo- N2 and P3 are the two major components in the neural time course of response inhibition (RI) and are both related, albeit differently, to dopamine (DA). However, contradictory results from previous studies imply that there may be an interaction effect between DA and task difficulty on the neural time course of RI. To investigate this, we assessed the correlation between spontaneous eye blink rate (EBR) and N2/P3 elicited by the Go/Nogo tasks across various task diff...

When classical music relaxes the brain: An experimental study using Ultrasound Brain Tissue Pulsatility Imaging
We report, for the first time, that classical relaxing music decreases the amplitude of the brain pulsatile movements related to cerebral blood flow and mechanical properties of the brain parenchyma, which provides further evidence of the involvement of BTP in emotional reactivity. In addition, we validate the use of TPI as a non-invasive, portable and low cost tool for studies in psychophysiology, with the potential to be implemented as a biomarker in musicotherapy trials notably.

A registered report of error-related negativity and reward positivity as biomarkers of depression: P-Curving the evidence
Publication date: Available online 24 January 2020Source: International Journal of PsychophysiologyAuthor(s): Peter E. Clayson, Kaylie A. Carbine, Michael J. LarsonAbstractPerformance-monitoring event-related brain potentials (ERPs), such as the error-related negativity (ERN) and reward positivity (RewP), are advocated as biomarkers of depression symptoms and risk. However, a recent meta-analysis indicated effect size heterogeneity in the ERN and RewP literatures. Hence, advocating these ERPs as biomarkers of depression might be premature or possibly misguided due to the selective reporting of significant analyses on the p...

Individual differences under acute stress: Higher cortisol responders performs better on N-back task in young men
This study assessed the role of cortisol responsiveness in the effects of psychosocial stress on working memory. To examine working memory processes, we analyzed both behavioral performances such as accuracy, response time, the inverse efficiency score, and event-related potentials (ERPs), including N1, P2, and P3. A total of 67 male college students completed a numerical 2-back task after being exposed to the Trier Social Stress Task (TSST) or a control task. The results showed shorter response time, better efficiency, and larger N1 and P2 amplitudes in the high-cortisol-responders compared to the low-cortisol-responders ...

In this study, 41 participants underwent fear acquisition and extinction, while SCRs and pupillary responses were recorded and separated into different time bins to explore the temporal dynamics of CRs across both learning phases. For SCRs, we observed a shift from early (FIR) to late (SIR) time intervals during fear acquisition most likely reflecting subsequent learning processes, in which CS-UCS associations and their relative timing are formed. During extinction, only the FIR exhibited a CR decline and was thus able to track the learning progress. These results indicate that conditioned SCRs follow a dynamic temporal pa...

Implicit learning of symmetry of human movement and gray matter density: Evidence against pure domain general and pure domain specific theories of implicit learning
Publication date: Available online 14 November 2019Source: International Journal of PsychophysiologyAuthor(s): Qian Zhang, Lin Li, Xiuyan Guo, Li Zheng, Yuyan Wu, Chu ZhouAbstractTheories of the neural basis of implicit learning postulated that specific regions were responsible for specific structures (e.g., supra-finite state) regardless of domain (e.g., vision, movement); others assumed that implicit learning was the adaptation that occurred within neural regions dealing with each domain. We explored whether people could implicitly learn to detect symmetry in biological motion, and if so, based on voxel-based morphometry...

Beyond prospective memory retrieval: Encoding and remembering of intentions across the lifespan
Publication date: Available online 14 November 2019Source: International Journal of PsychophysiologyAuthor(s): Alexandra Hering, Nele Wild-Wall, Michael Falkenstein, Patrick D. Gajewski, Katharina Zinke, Mareike Altgassen, Matthias KliegelAbstractCombining behavioral and electrophysiological measures, we investigated the role of memory processes for prospective memory development in three different age groups over the lifespan. We focused on age differences during intention encoding, retention and retrieval in order to assess if potential age-associated performance differences in adolescence and older age can be explained ...
