Accordingly, it should be assessed as early and accurately as possible, even if, to date, no consensus exists on how best to measure SA, and on its explanatory models. The present systematic review aimed to address: (a) to which extent ISA has been assessed in studies enrolling severe ABI patients; (b) whether studies on assessment of SA after severe ABI considered any explanatory models of SA and which measures have been utilized accordingly; (c) possible gaps or criticism in the extant research on severe ABI patients; and (d) to provide a novel proposal for SA assessment/classification based on the results and discussion from the systematic review conducted in this well selected population of patients. A systematic review was carried out in the databases PubMed, Web of Science and PsycINFO; 701 studies were retrieved and finally 54 met the inclusion criteria. Our review evidenced the paucity of studies on assessment of SA in patients with severe ABI that specified the model and the level of SA. Only a few measures of SA went beyond its intellectual and declarative aspects, thus hindering an exhaustive assessment and a full comprehension of SA. Accordingly, we propose a more comprehensive classification of offline anticipatory SA, with some important implications in the neurorehabilitation field. The review demonstrated the need of measuring SA beyond its declarative level, differentiating between declarative and real anticipatory SA, as well as of assessing SA at both offline and online levels.</p>","PeriodicalId":19279,"journal":{"name":"Neuropsychologia","volume":" ","pages":"109123"},"PeriodicalIF":2.0,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143634145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thirty participants (21 (±5) years, 7 males) completed five FPVS-oddball conditions that implicitly measured their ability to discriminate an oddball line orientation (1°,5°,10°,30°,80°), from a standard vertical line, as well as an equiprobable control condition.

The magnitude of this oddball response increased as oddball lines deviated more from vertical. Demonstrating consistency in individual participants, oddball responses were present in 30/30 participants in response to a deviation of 30° and 29/30 in response to a deviation of 80°. At larger deviations, oddball responses were highly reliable between sessions, measured using intraclass correlations. Overall, this study showed that FPVS-oddball can consistently and reliably measure line orientation discrimination in individual participants.

In recent years, FPC function has begun to be described within the context of value-based decision making in terms of monitoring the value of alternatives and optimizing cognitive resources to balance the explore/exploit dilemma in the face of volatile environments.

More recent work has proposed that cognitive planning preceding the execution of enactment, via engagement of frontal lobe-based processes, is most critical for the memory benefit. Here, evidence for these two accounts was assessed by comparing memory in healthy controls relative to individuals with lesions to parietal or frontal brain areas. Frontal stroke participants and controls both showed significant enactment effects: Recall was better for words enacted at encoding relative to those that were silently read.

Participants’ verbal descriptions of each memory were recorded in synchronisation with their eye movements and pupil size during recall. For each memory participants described the place (details of the environment where the event took place) and the event (details of what happened). Narratives were analyzed using the Autobiographical Interview procedure, which separated internal spatial (place) and non-spatial (event, thoughts and emotion) details. Eye movements during recall of spatial details had significantly higher fixation duration and smaller saccade amplitude and peak velocity, and a higher number of consecutive unidirectional saccades, in comparison to recall of non-spatial details. Recurrence quantification analysis indicated longer sequences of refixations and more repetitions of the same fixation pattern when participants described spatial details. Recall of spatial details was also associated with significantly greater pupil area. Overall findings are consistent with the spontaneous production of more structured saccade patterns and greater cognitive load during the recall of internal spatial episodic scene details in comparison to episodic non-spatial details.
