Abstract

Social belonging is an important human drive that influences mood and behavior. Neural responses to social exclusion are well-characterized, but the specificity of these responses to processing rejection-related affective distress is unknown. The present study compares neural responses to exclusion and overinclusion, a condition that similarly violates fairness expectations but does not involve rejection, with a focus on implications for models of dorsal anterior cingulate cortex (dACC) and anterior insula (AI) function. In an fMRI adaptation of the Cyberball paradigm with adolescents aged 11.1-17.7 years (N = 69), we employed parametric modulators to examine scaling of neural signal with cumulative exclusion and inclusion events, an approach that overcomes arbitrary definitions of condition onsets/offsets imposed on fluid, continuous gameplay. We identified positive scaling of dACC and posterior insula response with cumulative exclusion events, but these same regions exhibited trending signal decreases with cumulative inclusion events. Furthermore, areas within the dACC and insula also responded to context incongruency (throws to the participant in the exclusion run; throws between computer players in the overinclusion run). These findings caution against interpretations that responses in these regions uniquely reflect the affective distress of exclusion within social interaction paradigms. We further identified that the left ventrolateral PFC, rostromedial PFC, and left intraparietal sulcus responded similarly to cumulative exclusion and inclusion. These findings shed light on which neural regions exhibit patterns of differential sensitivity to exclusion or overinclusion, as well as those that are more broadly engaged by both types of social interaction.

TL;DR

In an fMRI Cyberball study with 69 adolescents, the authors compared neural responses to social exclusion versus over-inclusion using parametric modulators for cumulative events. They found that dACC and posterior insula scaled positively with cumulative exclusion but also showed trending decreases with cumulative inclusion, cautioning against interpreting these regions as uniquely reflecting exclusion-related affective distress.

Key findings

  • Across ROIs, regions including ACC parcels, VS, left inferior frontal gyrus, and left posterior cingulate cortex showed significant signal increases with Increasing Exclusion after correction. The most superior/caudal dACC parcel showed greater signal for Increasing Exclusion than Increasing Inclusion, t(68)=2.97, p=.004, with signal increases for Increasing Exclusion (M=0.06, SE=0.02, t(68)=3.02, p=.003) and decreases for Increasing Inclusion (M=−0.11, SE=0.05, t(68)=−2.06, p=.043), though these ROI findings did not survive correction for multiple comparisons.
  • Whole-brain analyses found that the contrast Increasing Exclusion > Increasing Inclusion identified clusters in left motor cortex, right posterior insula, and supplementary motor area extending into dACC. The conjunction of Increasing Inclusion and Increasing Exclusion identified shared signal decreases in left intraparietal sulcus and shared increases in rostromedial PFC; left ventrolateral PFC and rostromedial PFC responded similarly to cumulative exclusion and inclusion.
  • Context-incongruent events (throws violating the run’s inclusionary/exclusionary context) engaged dACC, left anterior insula, and bilateral posterior insula, among other regions.
  • Exploratory analysis found a positive association between need-threat scores and Increasing Exclusion signal in a functionally defined dACC ROI (B=.06, SE=.03, t(66)=1.83, p=.072; without outliers t(63)=2.51, p=.0146). Age showed a trending negative association with VS response to Increasing Exclusion (B=−.03, SE=.017, t(67)=−1.99, p=.050; not significant after correction; without outliers t(63)=−1.80, p=.077).

Methods

  • Participants were 69 community adolescents aged 11.1–17.7 years (M=14.2, SD=1.5; 36 female) from an original 97 recruited; exclusions included dropout, no MRI, pilot task, incomplete task, technical error, and motion/signal dropout.
  • fMRI adaptation of Cyberball with separate over-inclusion and exclusion runs, each 44 throws, interspersed with fair play. In the inclusion run, 17 of 27 other-player throws were to the participant (63%); in the exclusion run, 6 of 38 were to the participant (16%). Inclusion always preceded exclusion.
  • Analyses used event-related GLM with parametric modulators for consecutive inclusion throws (Increasing Inclusion) and consecutive exclusion throws (Increasing Exclusion), ROI tests in ACC parcels, anterior insula, left inferior frontal gyrus, posterior cingulate cortex, and ventral striatum, plus whole-brain conjunction/subtraction and a 2×2 repeated-measures ANOVA for event type by context. Need-threat was measured post-scan with the 12-item Need-Threat Scale (mean=3.23, SD=.73).

Limitations

  • The paper states that conditions were not counterbalanced: over-inclusion always preceded exclusion, so order effects cannot be ruled out. It also states that condition intensity was imbalanced, with a greater average number of cumulative events for Increasing Exclusion (M=5.97, SD=3.89) than Increasing Inclusion (M=2.73, SD=1.82), and few incongruent throws, reducing precision for some conditions.
  • The paper notes that only inclusion throws required a button press, creating asymmetrical motor demands, and that the linear parametric modulation may not capture the true shape of neural trajectories over longer interactions. Need-threat was assessed retrospectively, in reference to Cyberball generally rather than a specific run, and without a baseline measure.
  • Evident from the text: eight participants reported psychiatric diagnoses or psychotropic medication use, and eight indicated disbelief in the peer manipulation; sensitivity analyses excluding these participants (N=61) generally preserved the main pattern but some effects changed. The sample is a community adolescent sample, so findings may not generalize to clinical or other age groups.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-10.
