This study examined whether the proximity principle adheres to Weber's law and how orientation biases modulate this relationship. Rectangular dot lattices were used to generate the stimulus set at four different scales. The method of limits was used to extract psychophysical difference thresholds for proximity grouping and to derive Weber curves, including the point of subjective equality, just noticeable difference (JND), and Weber fraction. To achieve this, the perceptual shift between different grouping percepts was induced by gradually varying interdot distances along one direction in ascending and descending sequences, whereas distances in the other direction were held constant. Twenty-four right-handed individuals (13 women, 11 men) participated in the experiment. Linear mixed-effects models were used to analyze the collected data. The results revealed a strong preference for vertical orientation and a slight tendency toward a 135° orientation. More importantly, a linear increase in the JND and a constant Weber fraction were observed across lattice scales. These findings indicate that the proximity principle adheres to Weber's law in both axis orientations. However, the vertical bias resulted in decreased sensitivity and resolution in detecting stimulus changes along the orthogonal axis, as evidenced by a higher JND slope and Weber fraction.

First, we report the typical influence of knowledge of the upper-limb biomechanics on apparent movement perception and perceptual extrapolation in two individuals born without limbs (Experiments 1 and 2).

We report two preregistered experiments, designed to disentangle and examine the specific effects of phasic and tonic alerting on distinct attentional processes, independent of motor responses. Using a phasic/tonic/no-alerting design with a purely accuracy-based letter recognition task, we apply computational modeling to analyze whether alerting influences perceptual thresholds, processing speed, visual short-term memory, spatial weighting, and top-down control. Results show that phasic alerting significantly enhances visual processing speed without affecting other attentional parameters, including top-down control. These results suggest that, in the absence of motor confounds, the interaction between alerting and cognitive control may be more limited than previously assumed in Posner and colleagues' attention network theory. In addition, results show that exposure to phasic alerting does not influence tonic alertness levels. This dissociation establishes a novel, methodological framework for isolating phasic alerting effects in attentional tasks, free from tonic confounds. Our findings highlight the distinct role of phasic alerting in accelerating visual processing globally rather than selectively, thus advancing our understanding of attentional dynamics in complex environments.

Prior research has shown that gradiency facilitates recovery from misperceptions (i.e., speech perception flexibility) in L1 (Kapnoula et al., 2021), but whether and how gradiency contributes to speech perception flexibility in L2 remains unknown. This study investigated the role of gradiency in spoken-word recognition among Spanish (L1)-English (L2) bilinguals. Gradiency was assessed using a Visual Analogue Scale with stop consonants (/b/-/p/), and initial activation of a lexical competitor and speech perception flexibility were assessed using an eye-tracking Visual World Paradigm task. Seventy Spanish-English bilinguals completed these tasks in both languages. Following previous results in L1 English, gradiency facilitated speech perception flexibility in L1 Spanish. In contrast, gradiency did not facilitate L2 speech perception; instead, a different pattern emerged: participants relied more heavily on lexical (top-down) than subphonemic (bottom-up) information, as would be expected given the less robust category representations in L2. In addition, a positive correlation between L1 and L2 gradiency was observed only among higher-proficiency listeners. Overall, these findings suggest that the functional role of gradiency in L1 versus L2 speech perception is modulated by the differential reliance on bottom-up versus top-down information.

In this paradigm, it is typically observed that memory performance is enhanced for cued items compared with a no-cue control. Several mechanisms have been proposed to explain the retro-cue benefit; here we revisit 2 of them. To investigate whether the retro-cue protects from memory decay, we varied the time between encoding and the memory test using verbal (Experiments 1, 2, and 4) and visual memory materials (Experiment 3). To test whether the retro-cue protects from perceptual interference, we manipulated the presence of test-display interference using verbal (Experiment 5) and visual memory materials (Experiment 6). The retro-cue benefit was observed when test-display interference was present, or when there was time for decay after the onset time of the retro-cue in the cue and the control condition. When both were taken away or strongly minimized, the retro-cue benefit disappeared. Therefore, memory performance benefits from focused attention because focusing attention protects information from memory decay and from perceptual interference at test.

On each trial, a high-value distractor is placed near one option, and a low-value distractor is placed near the other. If value is automatically processed (and the options and distractors are nonindependent), then the distractors will have a predictable influence on choice.

Here, we examined whether listeners' language backgrounds influenced change detection of speech in auditory scenes. Adult listeners from three language backgrounds (English monolingual, English-Mandarin bilingual, and English-other language/non-Mandarin bilingual) completed a change detection task in which they determined whether pairs of auditory scenes consisting of speech (nonsemantic English and Mandarin sentences), music, environmental, and animal sounds were the same or different from each other. We replicated the attentional bias toward speech and showed that only English-Mandarin bilinguals detected Mandarin speech changes as well as English speech changes. Beyond a general bias toward all human speech, listeners are biased toward speech in their known language(s).

A commonly observed learning strategy that may reflect the interplay between exploration and exploitation involves holding a joint or a motor parameter constant while varying other degrees of freedom. By examining the relative variability between two deciding parameters of a novel single-joint motor learning task, we quantify usage of this strategy and relate it to motor learning and performance. In addition, we ask how experimentally induced motor variability, in the form of a persistent, variable visual feedback delay, affects the exploration and exploitation trade-off and usage of this strategy. The results showed participants alternated between periods where one motor control parameter was suppressed while the other varied. The transition away from this strategy is linked to motor performance. Furthermore, variable visual feedback delay slowed down this transition, thus hurting motor performance. We suggest that uncertainty from the variable feedback delay interferes with the effectiveness of the exploration of potential control solutions, resulting in a shift to a more systematic strategy.

Pauly and Wentura (2025) showed that a significant part of the self-prioritization effect can be explained by the PCP. One half of the participants reacted with a (positively coded) \"yes\"-response to self-matching trials (in those trials, a positively coded label and shape are shown) and the other half with a negatively coded \"no\"-response. The self-prioritization effect was significantly reduced for the second half, which was attributed to the lack of polarity correspondence in self-matching trials. If WPEs can also be explained by polarity correspondence, a similar manipulation should lead to a significant reduction in the WPE. In a first experiment, we used a minimal group approach to induce group membership and replicated the WPE. In the second experiment, we varied task instructions between participants. Half of the participants reacted to matching trials with a positively coded response, the other half with a negatively coded response. The first half of the participants showed a significant WPE. For the second half, the WPE was significantly reduced but still existed. We conclude that the PCP can also be applied to the WPE and that a significant amount of this effect can be explained by the encoding of stimulus and response alternatives in general.
