Abstract While recounting an experience, one can employ multiple strategies to transition from part the next. For instance, if event was learned out of linear order, recall events according time they were (temporal), similar (semantic), occurring nearby in (chronological), or produced by current (causal). To disentangle importance these factors, we had participants watch nonlinear narrative, Memento, under different task instructions and presentation orders. each scene film, also separately computed semantic causal networks. We then contrasted evidence for temporal, semantic, chronological, during recall. Critically, there stronger chronological than temporal strategies. Moreover, outperformed even when asked film presented underscoring fundamental nature structure scaffolding understanding organizing Nevertheless, still marginally predicted transitions, suggesting it operates as a weak signal presence more salient forms structure. In addition, network properties memorability, including role incoming causes its outgoing effects. summary, findings highlight accounting complex, networks knowledge building memory.

Animacy semantic network supports implicit causal inferences about illness

Опубликована: Май 2, 2025

Inferring the causes of illness is a culturally universal example causal thinking. We tested hypothesis that implicit inferences about biological processes (e.g., illness) depend on animacy semantic network. Participants (n=20) undergoing fMRI read two-sentence vignettes elicited across sentences, either emergence or mechanical breakdown inanimate objects, in addition to noncausal control vignettes. All were people and linguistically matched. The same participants performed localizer tasks: language, logical reasoning, mentalizing. causes, relative all conditions, selectively engaged portion precuneus (PC) previously implicated representation animates people, animals). Neural responses adjacent but distinct from mental state inferences, suggesting neural mind/body distinction. failed find evidence for domain-general inference. Implicit are supported by content-specific networks encode knowledge.

Negative emotion reduces the temporal compression of events in episodic memory

Cognition & Emotion, Год журнала: 2025, Номер unknown, С. 1 - 16

Recent studies have revealed that the continuous flow of information characterises naturalistic events is temporally compressed in episodic memory, so remembering an event generally takes less time than duration past episode. However, specific characteristics influence its temporal compression memory remain poorly understood. In present study, we examined extent to which negative valence impacts their rate representations. We conducted two experiments participants were instructed mentally replay a series videos depicting or neutral events. The results showed taken video, relative actual video duration, was significantly longer for videos. These suggest emotion increases sampling units experience represent course events, leading lower
