Specifically, the congruency effect is larger in mostly congruent (MC) blocks compared to mostly incongruent (MI) blocks. Research has shown that adaptation to these blocks does not change symmetrically when transitioning between them: moving from MC to MI leads to a rapid decrease in the congruency effect while transitioning from MI to MC results in little or no increase (Abrahamse et al., 2013). We aimed to investigate this asymmetric list shift (ALS) effect in a within-participants design where all participants experienced both transitions (MC-MI and MI-MC). Throughout Experiments 1–3 using a color-word Stroop task, we identified various forms of practice – including trial-type, stimulus-specific learning, general RT decrease, and a decrease in congruency effects over time (see Schmidt, 2016) – that can either facilitate or obscure the ALS effect, depending on the order in which participants experienced the transitions. In Experiment 4, using a face-name version of the Stroop task, where we minimized practice-related confounding factors by employing more complex stimuli and used a new stimulus set in the second transition, an ALS effect was observed regardless of the order of transition and for frequency-unbiased (i.e., 50% congruent) items. The role of practice effects and implications for the (in)-flexibility of control adaptations will be discussed.</p></div>","PeriodicalId":55433,"journal":{"name":"Attention Perception & Psychophysics","volume":"88 5","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.3758/s13414-026-03284-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148213397","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}

This study investigated the effects of the presence versus absence of a fixation point on monocular size–distance scaling, examining whether it functions as a fixation stabiliser, a spatial anchor (i.e., as a direct depth or location cue), or a competing visual reference. Using a widely employed fixation marker, we compared size and distance judgments for real objects and afterimages (stimuli that differ in their reliance on depth cues). Fixation points modestly improved size constancy for both stimuli, supporting their role in retinal stabilization. However, their effects on distance perception varied: real objects maintained stable distance judgments regardless of fixation, whereas afterimages exhibited greater inconsistencies when a fixation point was introduced. Therefore, fixation points appear to interfere with distance scaling for depth-ambiguous stimuli like afterimages. Additionally, correlations between accommodative abilities and errors in size perception for real objects suggest fixation points may reduce reliance on oculomotor cues by stabilizing retinal input. These findings challenge the assumption that fixation points are neutral methodological tools, highlighting their active role in shaping perceptual outcomes. Future research should critically evaluate fixation point designs and their broader impact on size and distance perception.</p></div>","PeriodicalId":55433,"journal":{"name":"Attention Perception & Psychophysics","volume":"88 5","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.3758/s13414-026-03272-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148201104","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}

As reading involves visual sampling and language processing, various studies investigate how the linguistic information of texts influences visual behaviour.

Here, we show that relative saccade length distributions reveal similarities and differences in gaze dynamics during reading and shape-scanning. In a within-subject design, participants read texts and scanned a spatially matched array of geometric shapes. We find that the lengths of consecutive saccades in target direction are more consistent during reading than during shape-scanning, suggesting that saccadic planning is more constrained during reading. The consistency of eye movements opposite to the target direction does not differ for the experimental conditions. These results consolidate findings from neurocognitive studies on the vision–language interface and suggest how underlying neural structures manifest themselves in observable visual behaviour. Furthermore, the results indicate that relative saccade lengths could present a new measure for investigating how linguistic processing influences human visual behaviour during reading. More broadly, the results suggest that analysing gaze behaviour dynamics via relative saccade lengths might provide novel insights into similarities and differences across tasks.</p></div>","PeriodicalId":55433,"journal":{"name":"Attention Perception & Psychophysics","volume":"88 5","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.3758/s13414-026-03289-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148151787","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}

This study assessed how narrowband light of different wavelengths affects two-point separation thresholds under controlled stimulus and ocular conditions. Action spectra for fine spatial resolution were measured using an equal-energy approach. Sixty healthy young adults (mean age: 22.7 ± 3.3 years) with normal vision were tested in a two-point resolution task. Narrowband stimuli (420–660 nm) and a broadband white condition were produced by a 1,000-W Xenon arc lamp with interference filters. Participants were preselected for optimal acuity. Thresholds, defined as the minimum resolvable separation between two-point sources (two-point separation thresholds), were recorded using a digital micrometer, and converted to visual angle for analysis. Separation thresholds varied significantly with wavelength with short-wave light (420 nm) yielding poorer resolution compared to long-wave light (660 nm). Iris pigmentation (color, lightness, and a combination of color + lightness) also influenced performance with lighter irides associated with higher thresholds, and the largest group differences observed at short wavelengths. Two-point resolution shows systematic wavelength dependence under equal-energy conditions, with performance degraded in the short-wave range. These effects likely reflect the combined influence of chromatic aberration, optical scatter, and photoreceptor sampling, rather than scatter alone. Consideration of both optical and neural mechanisms is essential when interpreting wavelength-dependent changes in spatial vision.</p></div>","PeriodicalId":55433,"journal":{"name":"Attention Perception & Psychophysics","volume":"88 5","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13221314/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148058250","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}

However, attempts to replicate this result have been challenging, potentially due to limitations or confounds in the experimental design, or difficulties in inducing context-specific learning due to item-specific cues. The present study aimed to reevaluate the memory-guided hypothesis using the trial-unique Stroop paradigm, where each trial consists of a unique stimulus and response that never reappear throughout the experiment, thereby preventing trial-to-trial associative regularities. One context was associated with high conflict (20% proportion congruency), and the other with low conflict (80% proportion congruency). Experiment 1 demonstrated that trials within the low-conflict context exhibited larger congruency effects compared with those in the high-conflict context, aligning with the memory-guided selective attention hypothesis that attentional priorities become associated with contextual cues and are automatically reinstated through memory retrieval. Experiment 2 replicated this finding and examined whether both auditory and visual context cues were necessary by assigning participants to combined auditory–visual, auditory-only, or visual-only conditions. The context-specific proportion congruency effect was successfully replicated in both the combined and visual-only conditions, but not in the auditory-only condition, suggesting that visual contextual cues may be more effective than auditory cues. These findings provide compelling evidence for memory-guided selective attention while revealing important boundary conditions regarding contextual cue effectiveness.</p></div>","PeriodicalId":55433,"journal":{"name":"Attention Perception & Psychophysics","volume":"88 5","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148044679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Holistic face processing is disrupted when the top and bottom halves are vertically separated by a substantial amount. This was attributed to the biological implausibility of the elongated faces—a domain-specific explanation. However, more recent findings of face-like holistic processing of stimuli with strong perceptual grouping cues suggest that such cues support holistic processing more generally. If so, the breakdown of holistic processing with vertical separation may reflect a disruption to perceptual grouping mechanisms rather than to face-specific mechanisms. We tested this hypothesis across three experiments. Experiment 1 used a modified composite part matching paradigm to replicate previous results—vertically separating the halves in a composite face paradigm disrupted holistic face processing. Experiment 2 demonstrated that vertical part displacement similarly disrupted holistic processing of non-face stimuli rich in perceptual grouping cues, which are not constrained by biological plausibility. Experiment 3 revealed that horizontal misalignment—a standard method of disrupting holistic processing—does not further diminish holistic processing of vertically displaced non-face stimuli, consistent with the interpretation that holistic processing was already disrupted for these stimuli. These findings support a disrupted perceptual grouping, rather than biological implausibility, account of the disruption to face holistic processing with vertical part misalignment. This has implications for understanding face processing and, given the role of holistic perception in supporting perceptual expertise, skilled perception more broadly.</p></div>","PeriodicalId":55433,"journal":{"name":"Attention Perception & Psychophysics","volume":"88 5","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13186796/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147977405","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}

Listeners must segregate speech streams, and selectively attend to the target talker while filtering out irrelevant speech. Research on value-driven attention suggests that perceptual and attentional processes are biased by prior rewarding experiences with stimuli—that is, high-valued stimuli win attentional competition. However, it remains unknown whether such effects generalize to speech perception in multitalker environments. Here, the present study investigated whether listeners can better understand speech spoken by talkers associated with higher versus lower values in challenging listening conditions. In three experiments, we used reward-based training paradigms to either explicitly or implicitly induce listeners to associate talkers’ voices with varying magnitudes of rewards. Subsequently, listeners performed a speech-on-speech intelligibility task in which the exposed voices were either the target or distractor. We found that explicit talker–reward learning did not influence speech intelligibility. In contrast, we observed that implicitly acquired talker–reward associations improved the intelligibility of high-reward talkers, but only in the most adverse listening condition. However, this effect did not replicate when we further imposed greater attentional demands by presenting target and masker talkers’ speech without spatial separation. Instead, listeners relied primarily on acoustic cues other than reward-associated talkers’ voices. Furthermore, the reward values associated with the distractor talker had no effect on interference. These findings suggest that value associated with talkers’ voices do not reliably bias listeners’ attention to overcome the complex, acoustic constraints imposed in speech-on-speech perception.</p></div>","PeriodicalId":55433,"journal":{"name":"Attention Perception & Psychophysics","volume":"88 5","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.3758/s13414-026-03276-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147938811","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}
