Memory systems constantly confront the challenge of capturing both shared features that connect experiences together and unique distinguish them. Across two experiments, we leveraged a color memory distortion paradigm to investigate how handle this representational tension when learning new information. Over thirty-minute period, participants learned categories novel objects, where each feature was assigned particular color. While did not differ in accurately they remembered these overall, inaccurate, misremembered (relative unique) as more similar category's average color, suggesting integration memory. This same rapid warping manifested neural network model trained on categories. The work reveals memories for different are rapidly differentially warped function their roles category.

Early caregiving experiences have strong, persistent links to emotion regulation. In this article we offer a view that the content represented in emotion-regulation neurobiology part reflects consolidated interpersonal-affective memories abstracted from early experiences. We suggest these memories, referred here as “attachment schemas,” are by cortical-subcortical (re)activations. Neural circuitry involving functional connections between subcortical and midline cortical regions is well positioned generate predictive inferences attachment schemas implications for Although speculative, perspective motivated convergence of empirical findings cognitive developmental neuroscience. Situating affective neural predictions within neurodevelopmental framework has great potential uncover mechanisms ultimately build toward more complete understanding emotional well-being.

Previous research has highlighted the critical role of prediction errors (PEs) in signaling need to adapt memory representations response unexpected changes environment. Yet, influence PE type and strength on remains underexplored. In this study, participants encoded naturalistic dialogues prior undergoing fMRI scanning. During session, they listened that had been modified their surface or gist, varying extents. As expected, our findings revealed robust activation inferior frontal gyrus for all PEs. Notably, gist modifications elicited additional activations within episodic network, including hippocampus. A post-fMRI recognition test demonstrated no significant impact memory. Conversely, weak impaired original content hindered learning modification. These also triggered parahippocampal cortex. results underscore importance both PEs shaping brain outcomes, highlighting complex interplay cognitive processes.

Schemas are affective-cognitive conceptual models of self, others and the world, derived from life experience. Predictive Coding theory proposes schema created perceptual input as follows: Based on previous similar experiences, brain generates schema, with "predictions," expectations future sensory experiences. Discrepancy between predicted versus actual experience produces a "prediction error." Exposure to prediction errors considered more certain than predictions prompts hippocampus update revise schema. Hypothesized underlying mechanisms include memory reconsolidation, extinction pattern separation. Depression is characterized by negative schemas predicting helplessness, hopelessness worthlessness. Early maladaptive schemas, childhood, implicated in mediating greater risk depression childhood maltreatment.

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

Previous research has established that the brain uses episodic memories to make continuous predictions about world and prediction errors, so mismatch between generated reality, can lead memory updating. However, it remains unclear whether errors stimulate updating in for naturalistic conversations. Participants encoded dialogues, which were later presented a modified form. We found larger modifications associated with increased learning of statement. Moreover, original version statement was weakened after medium-strong resulted from interplay modification extent strength previous memory. After strong both well-remembered. Prediction thus play role keeping representations statements therefore socially relevant knowledge others up date.
