Recent evidence suggests the FoA can flexibly adjust to hold early, middle, or terminal memory representations in a highly active state with adequate motivation. When a high-reward item is present, the FoA can be redirected to flexibly adjust and select prioritized items, leading to improved performance. This has been termed the prioritization effect. This finding has been demonstrated across prior investigations that have consistently used the color red to indicate the high-reward stimulus. The salience of the stimulus may alternatively explain the prioritization effect in that the salient item may have an easier time entering WM. Salience could influence memory performance through better encoding. The current study aims to test the effect of feature-based confounds (pop-out effect) on reward-based prioritization by using a probe-recognition task and alternating the color of the to-be-prioritized item. Four colors (red, green, blue, magenta) were used, and the color assigned to a higher point-value was randomized between subjects. Our results showed that the prioritization effect was still evident even when salience (pop-out) was controlled. Regardless of the color used there was a performance benefit for the prioritized list position. Comparisons with prior studies indicate that visual pop-out, while not necessary for prioritization, may help facilitate stronger reward effects.

Previous work has shown that lower-level cues, like acoustic information, and higher-level cues, like semantic information, can be integrated across the course of an utterance in order to categorize words. Questions remain about how these bottom-up and top-down sources are integrated. We propose that a useful approach to this problem is to compare human behavior to normative models of cue integration, such as ideal observer models, which have been successful in other domains. We argue that ideal observer models make three key predictions about how acoustic and semantic information should be integrated during word recognition: (1) additivity: cues have additive effects on categorization; (2) transitivity: cues providing identical information should be treated identically regardless of their temporal order; and (3) reliability weighting: cues should be weighted according to their absolute and relative reliabilities. We conduct two spoken-word recognition experiments in which participants categorize a target word embedded in a sentence. We manipulate acoustic cues on the target word; semantics from the sentence; the cues’ relative timing, and the degree of noise affecting each cue. We find evidence for additivity and transitivity; we also find evidence in favor of absolute reliability driving cue reweighting, but more mixed evidence on the role of relative cue reliability. Overall, our results suggest that listeners are near-optimal in their integration of information across multiple levels of the linguistic hierarchy over time. We also discuss how these results relate to recent error-driven approaches to cue weighting.</p></div>","PeriodicalId":55433,"journal":{"name":"Attention Perception & Psychophysics","volume":"88 6","pages":""},"PeriodicalIF":2.0,"publicationDate":"2026-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.3758/s13414-026-03280-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148261981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we evaluate whether people are not only sensitive to differences in the presence or absence of certain topological features, but also to their exact spatial arrangement. In a first experiment, we show that people distinguish figures which possess all the same topological features as other figures in a set if the features differ in spatial arrangement. In a second experiment, we show that people also match figures based on exact spatial arrangement. Finally, we show that memory encodes the correct relational structure of the figures: People are more likely to falsely indicate having seen an item if it shared the precise arrangement of topological features of other items they had seen (compared to a closely matched item which had the same features arranged in a different way).

Flankers could be located close to targets (normal spacing – close flankers) or separated from targets by seven spaces (distant flankers). Results revealed significant effects of flanker relatedness (same word as the target or a different word) that interacted with both flanker size and flanker eccentricity in the analysis of response times. The three-way interaction was not significant. The only significant effect in the analysis of error rates was that of flanker relatedness. We replicated prior findings showing that increasing flanker eccentricity diminishes the effect of flanker relatedness, and we further demonstrated that increasing flanker size increases the magnitude of flanker effects. Crucially, an increase in flanker size was not found to compensate for the negative impact of an increase in flanker eccentricity on effects of flanker relatedness. These results suggest that eccentricity is one key visual factor influencing the spatial integration of orthographic information, and that the impact of eccentricity overrides the impact of flanker size.

In six online experiments, participants foraged for multiple instances of two target types amongst two distractor types, defined by either features or conjunctions. Experiments comprised a series of manipulations of the presence, quantity, visibility, and availability of spatial structure. This was achieved via visibly segmenting displays into areas containing equal numbers of objects. These experiments assessed the effects of spatial structure on foraging using a broad range of measures and across variations including the presence of time limits and visual feedback within the display. Task-irrelevant spatial structure consistently encouraged systematic foraging, whereby participants were more likely to continue foraging within one display segment rather than to move to another. Foraging in this manner was associated with costs to foraging efficiency, and benefits to spatial memory. The general strength of the visual information about spatial structure modified the extent to which this information affected systematic foraging and foraging efficiency.

Stimuli were pairs of small visual probes that varied in their spatial separation from trial to trial. Participants (<i>N</i> = 366) performed a psychophysical task that required them to report occasional trials on which the separation between probes exceeded a criterion value.

However, it is unclear whether the selection profile for more complex stimuli follows a similar pattern. Using a recently developed circular shape space, the current study assessed the selection profile for these simple shapes as an initial step toward the study of object-based attention. Participants attended to two target shapes while ignoring two distractors, each overlapping with one target. They performed a change identification task, reporting luminance changes of only the target shapes. We systematically varied the difference between the two targets in the shape space. In two experiments covering different ranges in the shape space, performance accuracy peaked when the two target shapes matched and then decreased in a monotonic manner as the two shapes became more different. These results align with a feature-similarity gain model and suggest that an analogous shape-similarity gain effect operates for more complex stimuli.
