Using an eye-tracking methodology, we assess how ABs differ across three conditions involving two types of images: Food vs. Gambling, Food vs. Neutral, and Gambling vs. Neutral. Gamblers showed a significant AB toward gambling-related stimuli compared to neutral cues, supporting the IS model. However, when gambling and food images were compared, no significant difference in AB was found, partially disconfirming the hypothesis that gamblers exhibit a stronger bias toward gambling stimuli. In contrast, non-gamblers demonstrated a clear preference for food-related images, as predicted by the IS model. Additionally, group differences revealed that gamblers allocated more attention to gambling-related cues than non-gamblers. However, food images elicited similar levels of attention from both gamblers and non-gamblers when compared to neutral images, rather than gambling-related images. These findings highlight the role of ABs in the development and maintenance of gambling behaviour, supporting the IS model but not the RDS model. The study also explores the association between AB and severity of gambling and other relevant psychological factors in gambling disorder, providing new insights into the cognitive mechanisms underlying gambling addiction. These results suggest that ABs could be targeted in interventions aimed at modifying attention patterns and reducing gambling-related cravings.</div></div>","PeriodicalId":54945,"journal":{"name":"International Journal of Psychophysiology","volume":"216 ","pages":"Article 113245"},"PeriodicalIF":2.6,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144926764","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}

This study adapted the Joystick Operated Runway Task (JORT) for use with EEG to explore neural biomarkers of goal conflict related to the Behavioural Inhibition System (BIS), a key component of Reinforcement Sensitivity Theory (RST). A novel Trial Calibration System (TCS) was implemented to control motor activity and equate task difficulty across participants during high and low conflict conditions. Forty right-handed participants (aged 18–24) completed the EEG-adapted JORT, where conflict was manipulated by varying the speed of aversive stimuli. Behavioural data confirmed effective goal conflict induction: high conflict trials produced slower reaction times, more joystick movements, and a performance accuracy near 52 %, indicating a balanced conflict. EEG analyses using Current Source Density (CSD) transformations revealed increased right-frontal theta power and coherence during high conflict trials, consistent with BIS engagement. Left-frontal alpha power and coherence were more prominent during low conflict, while high conflict also produced elevated alpha power in parieto-occipital regions, suggesting roles in early threat detection and sensory integration. These results suggest that avoid-avoid goal conflict reliably activates BIS-related neural systems and that the updated JORT provides a valid method for studying anxiety-related biomarkers. Using a motor-calibrated framework, this is the first study to integrate EEG with an avoid-avoid conflict paradigm.

This study investigated whether the phonological familiarity of novel homophones aids the learning of orthographic forms and meanings or whether a mismatch between familiar sounds and new orthography creates obstacles to acquisition. Using Russian words, we created pseudohomophones that are identical in pronunciation to familiar words but have different spellings, as well as non-homophonic pseudowords that differ from familiar words in both pronunciation and spelling. Twenty-eight participants learned pseudohomophones and pseudowords in two experiments. We assessed orthographic and semantic acquisition using behavioral tasks and evaluated neural responses before and after learning using ERPs. Pseudohomophones were learned faster and their orthographic forms acquired better than those of pseudowords. Before learning, pseudowords elicited a larger N400 than familiar words, whereas pseudohomophones did not differ significantly, suggesting that phonological similarity hindered their distinction from real words. After learning, pseudowords showed modulations in the P200, N250-P325, and P600 components, reflecting the formation of new orthographic, phonological, and semantic representations. In contrast, only the P600 was modulated for pseudohomophones, likely because their phonology was already familiar. Moreover, comparison between pseudohomophones and pseudowords revealed greater modulation in frontal regions around 300 ms for pseudowords due to the learning session, indicating the formation of phonological representations and increased attentional demands. These findings are compatible with the connectionist dual-process model, suggesting a learning advantage for pseudohomophones based on existing phonological representations.</div></div>","PeriodicalId":54945,"journal":{"name":"International Journal of Psychophysiology","volume":"215 ","pages":"Article 113235"},"PeriodicalIF":2.6,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144724165","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}

Although recent research has demonstrated that prioritization in value-directed remembering relies on automatic and strategic mechanisms, it is controversial whether these mechanisms operate independently or synergistically to enhance memory selectivity. In particular, the neural correlations of how the underlying metamemory regulates these processes remain unclear. Thirty healthy adults completed an adapted value-directed remembering paradigm in which metamemory was manipulated through pre-encoding cues indicating the upcoming test form (recognition/free recall/unknown). During the encoding phase, participants studied high- and low-value words, and event-related potentials (ERPs) and time-frequency activity were recorded to examine the roles of automatic and strategic mechanisms, which was followed by a cued recall test. The results revealed that metamemory modulated resource allocation via N400 and frontal slow wave amplitudes and strategic selection through alpha- and theta-band time-frequency activity, collectively influencing the strategic mechanism. Specifically, time-frequency activity in the theta band related to the suppression of low-value items was more strongly correlated with memory selectivity than was time-frequency activity in the alpha band related to the selection of high-value items. The automatic mechanism indexed by the P2 amplitude is dynamically adapted to engage with the strategic mechanism. These findings provide the first neurophysiological evidence for metamemory-driven synergy between automatic and strategic mechanisms, validating responsible remembering theory.

Therefore, PAC is theoretically well-suited for ADHD research. However, the differences in PAC characteristics among children with ADHD subtypes have not yet been thoroughly investigated. This study recorded resting-state electroencephalographic (rsEEG) from 19 healthy controls (HCs), 33 children with predominantly inattentive type (ADHD-I), and 39 with combined type (ADHD-C). We examined intra- and inter-channel PAC differences across different spatial scales and further analyzed PAC-based brain network properties. The results showed that both ADHD subtypes had stronger α-γ PAC than HCs, with ADHD-C exceeding ADHD-I. ADHD-I showed mainly intrahemispheric changes, while ADHD-C involved the left hemisphere and occipital regions. In the α-β band, PAC was significantly higher in ADHD-C than in ADHD-I, mostly in the left brain. ADHD-I also showed increased inter-channel δ-β PAC compared to HCs, with widespread distribution. These findings suggest the presence of compensatory hyperactivation mechanisms in ADHD, particularly in the ADHD-C subtype. Further brain network analysis supported the “delayed maturation theory” of ADHD and indicated that ADHD-C may represent a shift from a typical small-world network architecture to a more regular network organization. Finally, the (Support Vector Machine) SVM classification results further validated the discriminative power of these features in differentiating HCs from ADHD subtypes. Overall, these findings indicate significant differences in PAC strength and brain network topology among ADHD subtypes, suggesting their potential as biomarkers for distinguishing HCs from ADHD subtypes.</div></div>","PeriodicalId":54945,"journal":{"name":"International Journal of Psychophysiology","volume":"215 ","pages":"Article 113222"},"PeriodicalIF":2.5,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144676631","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}
