However, because most of the MFT literature has focused on experimental within-subjects effects, the impact of particular data processing choices on individual difference analyses is not well understood. This study aimed to reduce that gap by examining the psychometric properties of different pipelines for measuring individual differences in MFT power and latency. Ninety-three adults aged 60 or older completed a flanker task during EEG recording. Stimulus-locked MFT was extracted in three primary pipelines via the fast Fourier transform (FFT), linear- and log-spaced wavelet, and filter-Hilbert analyses. The effects of frequency resolution, electrode choice, overall versus peak power, and trial type (overall, congruent, incongruent, and subtraction- and regression-based residual scores contrasting congruent and incongruent activity) were examined, as was the degree of overlap among related variables. Internal consistency reliabilities and associations with reaction times (RT) during the Flanker were assessed for select measures. Results indicated no benefit of higher frequency resolutions or region of interest over single-electrode measurements from FCz. Two-part coefficient alpha reliabilities ranged from 0.63 to 1.00 for MFT power variables, and from 0.02 to 0.83 for latency variables. Contrary to hypotheses and common criticisms of derived scores, correlations with RT were generally strongest for the difference and residual scores, with an additional benefit of time-frequency-based peak power relative to FFT-based overall power (r ~ = 0.30 vs. 0.45). These findings add to the growing literature on psychometric properties of EEG biomarkers, and help clarify measurement strategies that may enhance detection of behavioral and clinical correlates of MFT power and latency.</p>","PeriodicalId":54945,"journal":{"name":"International Journal of Psychophysiology","volume":" ","pages":"112555"},"PeriodicalIF":2.5,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143639696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An electroencephalogram (EEG) was used to collect error-related negativity (ERN) and error positivity (Pe) components, which index error detection and error awareness, respectively. Verbal reports were also employed to measure error awareness. Results showed that post-error slowing effects were present in all three conditions, with the smallest effect observed at SD-24. Post-error improvement in accuracy was only evident at SD-36. Error awareness was lowest at SD-24, with no significant difference between SD-36 and pre-SD. The Pe amplitude significantly reduced at SD-24.

This study explored whether spelling errors affect semantic processing by analyzing the behavioral and electrophysiological effects during sentence reading in 35 native Spanish-speaking young adults. The experimental paradigm consisted of 170 six-word sentences; the closing word of each sentence could be a) congruent, b) congruent with a homophone error, c) congruent with a typo error, d) incongruent, and e) incongruent with a homophone error. Participants performed a semantic decision task with simultaneous EEG recording, in which they were explicitly instructed to ignore spelling errors and to attend only to the semantic congruency of the sentence when responding. Behaviorally, accuracy only decreased with typo errors, while mean reaction times were significantly increased by both types of errors. Electrophysiological results showed a classic N400, in which orthographic errors had no effect, reinforcing the notion that this component is mainly determined by semantic incongruency. On the other hand, orthographic expectancy violations were reflected by a late slow positivity rather than a larger N400 amplitude suggesting that spelling information is not fully processed when deeper, more complex linguistic aspects of written language are being analyzed. This P600-like component is interpreted as signaling the re-evaluation of an error, regardless of whether it is semantic or orthographic in nature.</div></div>","PeriodicalId":54945,"journal":{"name":"International Journal of Psychophysiology","volume":"211 ","pages":"Article 112550"},"PeriodicalIF":2.5,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143588315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
