This price ending effect is thought to be driven primarily by two factors: the left-digit effect which occurs when a small price drop changes the leftmost digit, and the image effect which stems from the symbolic association of a particular price ending with low prices or sales. Our study aimed to investigate the neural basis of these irrational effects on perceived cheapness using functional magnetic resonance imaging (fMRI). We used five price values in Yen (197, 198, 201, 202, 206; Japanese consumers tend to perceive prices ending in the number 8 as cheap) for fMRI experiment. Participants were asked to rate the price value of a product. The “left-digit effect” was observed based on the deactivation in brain regions associated with visuospatial processing including the left lingual gyrus and posterior middle temporal gyrus, and the right dorsal posterior precuneus and anterior precuneus. From these regions, the degree of deactivation in the right dorsal posterior precuneus was negatively correlated with the irrational perception of cheapness. Furthermore, this region showed negative functional connectivity with the dorsal striatal regions. No regions were found with “the image effect”. Our results suggested that a decrease in activity in the regions associated with visuospatial processing suggests that changes in the leftmost digits alter the level of visuospatial attention towards the price, leading to an underestimation of the payment amount. This reduced attention might activate the dorsal striatum driving unconscious purchasing.</div></div>","PeriodicalId":55372,"journal":{"name":"Biological Psychology","volume":"197 ","pages":"Article 109030"},"PeriodicalIF":2.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143868577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We examined cardiovascular trajectories over a 6-day quarantine following common cold infection, utilizing data from the Pittsburgh Cold Study 3 (n = 213, 2007–2011). Specifically, we explored the relationship between depressive mood and heart rate (HR) patterns, hypothesizing that individuals prone to depressive mood might experience altered arousal during quarantine. We conducted similar analyses for blood pressure (BP) as well. Our findings revealed that, on average, HR increased during quarantine. Notably, individuals reporting higher depressive mood levels exhibited lower initial HR but experienced a sharper increase throughout the quarantine period. In contrast, no significant linear or quadratic changes were observed in systolic blood pressure (SBP). However, initial analyses did identify significant linear changes in diastolic blood pressure (DBP) and mean arterial pressure (MAP). These changes in DBP and MAP were not influenced by depressive mood and lost significance in sensitivity analyses that accounted for infection-related factors, health behaviors, and socio-demographic variables. Interestingly, HR trajectories remained significant in sensitivity analyses but lost significance when self-reported symptoms were included. Self-reported symptoms partially mediated the relationship between depressive mood and HR increases, suggesting that individuals with higher depressive tendencies also reported more infection-related symptoms, contributing to increased HR. These findings highlight how midterm social isolation can elevate HR, particularly in individuals prone to depressive mood.

Uniquely, the present project focused on survivors of the Cambodian genocide and the subsequent two generations to determine whether brain alterations are observable approximately five decades after the traumatic event and in subsequent generations from the same society. Using portable electroencephalography (EEG), we used four experimental tasks—two targeting non-affective processing (i.e., sensory gating, oddball) and two targeting affective processing (i.e., emotion recognition, threat processing). Results indicated that although the rate of PTSD symptoms was similar across generations, the affective reaction to threat for the LPP and FMθ was primarily observed or intensified in the directly affected generation (i.e., G0), regardless of the presence of PTSD. We also observed that G0 exhibited reduced attenuation over standard tones in the oddball task for the N100 and a reduced sensory gating effect on the auditory P200. The present study underscores that affective and non-affective alterations might still be present decades after a trauma, but are not necessarily observable in subsequent generations. Our results also support a dissociation between reported PTSD symptoms and neural alterations.</div></div>","PeriodicalId":55372,"journal":{"name":"Biological Psychology","volume":"197 ","pages":"Article 109028"},"PeriodicalIF":2.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143854775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SAI is calculated exclusively from ECG, while PEP requires both ECG and impedance cardiography (ICG) as inputs. An average of 1468 time series observations were analysed per participant per sympathetic index (SAI, PEP) across 17 participants (13 female). The mean SAI-PEP correlation increased significantly from baseline to stimulus (<em>r</em>_{<em>B-&gt;S</em>}<em>(16) = .22, p = 0.042)</em>, and then dropped from stimulus to recovery, back to near baseline levels <em>(r</em>_{<em>S-&gt;R</em>}<em>(16) = -.21, p = 0.047)</em>. Ideographic patterns emerged, although overall average PEP-SAI correlations were lower than expected, as the procedure did not include a physical stressor. Participants with the strongest positive SAI-PEP correlations (mean <em>r(1565) = .579, p &lt; 0.001</em>) had a matching pattern of psychological distress, as measured by Subjective Units of Distress Scale time series.

Results suggest that cardiac rate (SAI) and contractility (PEP) may reflect similar temporal dynamics when psychological and physiological stress patterns are aligned.

English-speaking students (n = 38) were asked to solve 120 compound word association problems, while pupil dilation was recorded. Subsequently, participants were asked to report which of the three problem-solving strategies (analytic, insight, combined) they had used to find each solution, without being if their answers were correct. A Bayesian linear mixed model analysis revealed an interaction between time-to-solution and strategy. More specifically, pupil dilation indexed an insight strategy for early solutions, but indicated an analytic strategy for late solutions, with combined strategies falling in between. In addition, correct trials were associated with greater pupil dilation. We conclude that, even within the same task, pupil dilation may separately indicate (1) the extended mental effort of problem analysis, (2) the immediate onset of insight, and (3) the feeling of uncertainty experienced when a correct answer is unvalidated by feedback.
