The word “zeitgeist” refers to common perceptions shared between members of a given culture. Meanwhile, defining feature loneliness is the feeling that one’s views are not with others. Does correspond deviating from zeitgeist? We demonstrate lonely individuals’ neural and semantic representations contemporary cultural figures deviate group-consensus representations, i.e., zeitgeist. Across two independent brain imaging datasets, participants exhibited idiosyncratic well-known celebrities strayed in medial prefrontal cortex—a region encodes retrieves social knowledge (Studies 1A: N=40; 1B: N=40). Because communication fosters connection by creating reality, we next asked whether lonelier participants’ about also deviates zeitgeist, possibly placing them at disadvantage finding ground Indeed, when strong group consensus exists for figure, individuals use language describe (Study 2: N=923). Collectively, results provide truth their More broadly, this suggests may only reflect impoverished relationships specific individuals, but feelings disconnection prevalently

Abstract Given the same external input, one’s understanding of that input can differ based on internal contextual knowledge. Where and how does brain represent latent belief frameworks interact with incoming sensory information to shape subjective interpretations? In this study, participants listened auditory narrative twice, a plot twist in middle dramatically shifted their interpretations story. Using robust within-subject whole-brain approach, we leveraged shifts neural activity between two listens identify where are represented brain. We considered terms its hierarchical structure, examining global situation models subcomponents–namely, episodes characters–are represented, finding they rely partially distinct sets regions. Results suggest our brains narratives hierarchically, individual elements being dynamically updated as part changing information.

Retrieval goals influence what individuals remember from past experiences. Previous research has demonstrated that adopting accuracy and social modify the content of an associated episodic memory. Age-related memory changes coincide with shifts in retrieval goals, leading to questions about how alter context aging. To answer these questions, we conducted a between-group experiment which younger older participants (N = 120) encoded audiovisual movie later recalled it either or goal. Following 24-hour delay, completed two recognition tasks—one assessing for narrative (i.e., story structure) another perceptual aspects movie. Using Natural Language Processing model, compared similarity between recollections. We found higher recalling goal, but no difference across adults. Examining memories retrieved revealed adults showed recall than Finally, outperformed both tasks, this effect was more robust task. These findings suggest aligning removes age-related differences recall, age persist as reduced ability tune access precise details

Here, we use intracranial recordings from participants viewing and freely recalling naturalistic stimulus. We show hippocampal HFOs increase following boundaries coincident hippocampal-cortical (co-HFOs) occur in cortical regions previously shown underlie segmentation (inferior parietal, precuneus, lateral occipital, inferior frontal cortices). also event-specific patterns co-HFOs re-occur subsequent three (in decaying fashion) recall. consistent with models support as memory consolidation.

Naive perspective-takers often perceive the social world in a simplistic and uniform way, whereas sophisticated ones recognize diversity complexity of others' minds. This commonly accepted distinction points to possibility greater inter-individual variability mentalizing for than naive perspective-takers, difference previously overlooked research. In current study, participants were asked watch mentalizing-related movie their neural responses, interpretations characters' mental states, eye-gaze trajectories recorded. The results provide robust converging evidence that connectomic features within network, trajectories, states exhibit among compared ones, supporting are more distinctive while similar.

Focusing on the upside of negative events often promotes resilience. Yet, underlying mechanisms that allow some people to spontaneously see good in bad remain unclear. The broaden-and-build theory positive emotion has long suggested affect, including positivity face events, is linked idiosyncratic thought patterns (i.e., atypical cognitive responses). evidence support this view been limited, part, due difficulty measuring processes as they unfold. To overcome barrier, we applied Inter-Subject Representational Similarity Analysis test whether and how neural responding supports reactions experience. We found functional connectivity brain's default network while resting after a experience predicts more descriptions event.
