Changes in autonomic nervous system activity were also assessed by measuring heart rate variability (HRV) and skin conductance levels before and during cognitive performance. Compared to the no-touch group, participants who received gentle, low-force, slow-moving touch demonstrated faster responses and higher HRV during the Stroop Task. Additionally, within the touch group, individuals with higher HRV exhibited even quicker performance on the cognitive task.

Specifically, we recorded electroencephalography from insufficiently active participants while they completed an oddball task wherein exercise images of different settings and types were embedded among positive, neutral, and negative non-exercise images. We extracted the P3b event-related potential component elicited by the exercise images to measure automatic affective valuations of the images.

The results of a mixed-effects model indicated that P3b amplitude was larger for outdoors and gym exercise images than indoors and sport exercise images, respectively, but these effects did not depend on whether the images were embedded among positive, neutral, or negative non-exercise images. This suggests the setting and type of exercise images influenced the degree to which they were cognitively processed but not their automatic affective valuation. We also found exercise images were explicitly perceived as neutral-to-positive and their setting and type did not affect this explicit affective evaluation.

Typically, shorter ISIs result in reduced N1 amplitudes, suggesting a decreased neural response with high stimulus presentation rates. However, an exception known as N1 facilitation occurs with very brief ISIs (∼150-500 ms), where the N1 amplitude increases. This study aimed to further characterize N1 facilitation using an experimental paradigm with a continuous distribution of ISIs (0.25 to 8 s) to identify the specific ISI where N1 facilitation occurs. We also examined the role of ISI history in N1 facilitation and explored correlations between N1 facilitation, overall N1 amplitude and ISI-sensitivity, and results of cognitive tasks. Twenty-nine participants passively listened to a random sequence of auditory clicks at varying intensities (65, 75, or 85 dB) and ISI ranges (0.25–0.5 s, 0.5–1 s, 1–2 s, 2–4 s, 4–8 s) while EEG was recorded.

Results support N1 facilitation occurring at ISIs under 400 ms (<em>p</em> = 0.03), where N1 amplitudes returned to values seen at longer ISIs (∼1.7 s). Notably, this effect was observed when the ISI two clicks before was shorter than 1.5 s (<em>p</em> = 0.001), but not otherwise (<em>p</em> = 0.37).

Participants (<em>N</em> = 36) completed a social evaluation task, awaiting feedback from liked and disliked peers with short (800–1200 ms) or long (5000–6000 ms) waiting times. Participants were more motivated to receive feedback from liked peers, and they rated acceptance from liked peers as more pleasant than rejection. Notably, participants found longer waits more worthwhile when receiving acceptance from liked peers, but less worthwhile when awaiting feedback from disliked peers. EEG results revealed that the RewP was increased for long waiting times for feedback from liked peers, and, conversely, reduced for long waiting times for feedback from disliked peers. Additionally, N170 and P3 were found to be sensitive to waiting time, with larger amplitudes for long compared to short waits. Overall, this study demonstrates that waiting time differentially affects social feedback processing, as reflected by changes in the N170, RewP, and P3. Our findings suggest that increased waiting time does not necessarily reduce reward value; it can enhance it depending on subjective social preferences. The increased N170 and P3 amplitudes during longer waits may indicate heightened attentional and memory demands.

Therefore, it is important to examine stress responses in controlled environments to obtain more insights in performance-influencing effects of acute stress. This study investigated the impact of passive heat exposure combined with virtual combat scenarios on cardiovascular and psychophysiological parameters in a controlled setting. Sixty-eight healthy servicemembers were randomized into a low-stress or high-stress condition. Both groups engaged in two virtual combat scenarios. The low-stress group, however, underwent testing under thermoneutral conditions (M_Temp = 22.4°C, M_{RelativeHumidity} = 41.4%) whereas the high-stress group was exposed to passive heat exposure (M_Temp = 35.9°C, M_{RelativeHumidity} = 66.4%) using a portable environmental facility. While virtual combat scenarios alone led to a decrease in heart rate variability (HRV) without affecting heart rate (HR), the addition of passive heat exposure elicited a more pronounced physiological stress response, characterized by significantly higher HR and lower HRV in the high-stress condition. However, no significant changes were observed in respiratory rate, salivary cortisol, or alpha-amylase levels across the conditions, suggesting that there was no activation of either the hypothalamic-pituitary-adrenal or the sympathetic-adrenal-medullary axis. Furthermore, subjective stress and anxiety scores did not differ between conditions, underscoring the physiological nature of the observed changes. Resultantly, the physiological response was likely a thermal reaction rather than an acute stress response. These findings highlight the importance of incorporating environmental stressors into military training protocols to enhance realism and prepare personnel for operational stressors. However, the mild response observed suggests that higher ambient temperatures and longer exposure times may be necessary to evoke a more robust stress response for effective stress inoculation training.</div></div>","PeriodicalId":54945,"journal":{"name":"International Journal of Psychophysiology","volume":"208 ","pages":"Article 112491"},"PeriodicalIF":2.5,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142877793","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}

There are many studies examining the neural mechanism underlying these behaviors; however, little is known about the potential role of payoff norms in social interactions. This study introduced two distinct payoff norms: zero-sum (ZS) and non-zero-sum (NZS). In the ZS group, only the player with the highest total score would receive a reward; while in the NZS group, rewards were determined by the combined total score of both players, and individual rewards were prorated according to each player's contribution to the total score. Electroencephalography was used to examine individuals' neural responses during the Chicken Game in these different groups. The behavioral findings revealed a higher rate of cooperation in the NZS group compared to the ZS group. Aggressive behaviors from opponents elicited larger feedback-related negativity (FRN) and lower P300 amplitudes in both groups. Notably, larger FRN and smaller P300 amplitudes were elicited by participants' aggressive behaviors compared to their cooperative behaviors in the ZS group, whereas larger P300 amplitudes were elicited by aggressive behaviors compared to cooperative behaviors in the NZS group. Additionally, a greater theta event-related synchronization (ERS) was observed solely when participants exhibited aggression in the NZS group. The type of group moderated the association between posterior theta-ERS and cooperative rates. Specifically, theta-ERS was negatively associated with cooperative rates in the NZS group, whereas a reversed association was found in the ZS group.
