Summary: This study explores the effect of saccade preparation on visual sensitivity in the center of gaze. The findings suggest that foveal processing anticipates soon-to-be fixated visual features during saccade preparation, enhancing the definition of eye movement targets. This enhancement is spatially confined to the center of gaze and develops faster than during passive fixation, contributing to trans-saccadic visual continuity.

Summary: Researchers have debated whether salient distractors automatically capture attention. Recent research suggests a potential resolution called the signal suppression hypothesis, which proposes that salient distractors produce a bottom-up signal but can be suppressed. However, this account has been criticized for using weakly salient distractors. This study introduces a psychophysical technique to measure salience and provides evidence that high-contrast singletons are more salient and can be suppressed.

Summary: The link between gaze and cognition may be more tenuous for dynamic stimuli, influenced by exogenous cues, with limited research on a small range of highly organized motion stimuli. The search for eye movement indices of cognition during dynamic naturalistic stimuli may be fruitful, but links are highly dependent on task and stimulus properties.

Summary: This review discusses how recent technological advances have allowed us to measure the information available to the visual system and the behaviors supported by it. It specifically focuses on the tasks performed by the binocular visual system and highlights the differences from the tasks considered during fixation on a static target. The article also discusses the challenges involved in generating a stable and useful binocular percept of the environment and highlights the limited addressing of these challenges in current clinical interpretation. The implications of new technology, such as virtual reality, in clinical and basic research applications are also emphasized.

Summary: The study found that exogenous attention transiently modulates visual detail in the foveola, enhancing detail discrimination ability at the cued location without extending to nearby locations. On a longer timescale, an inverse effect was observed, with sharper acuity at unattended locations resembling inhibition of return at larger eccentricities.

Summary: This study investigates the attractor dynamics of working memory in primates and corvids. The researchers found that corvid working memory exhibits similar behavioral biases as humans, and discrete attractors are evenly spread across the stimulus space. By comparing different species, the results strengthen the view of attractor dynamics as a general biological principle for efficient use of working memory.

Summary: Learning to categorize involves attending to relevant features and ignoring irrelevant features, with feature variability across objects aiding in inferring category membership rules. While participants' categorization accuracy improved with practice, their attentional focus did not show improvement. Despite eyes being a salient feature attracting attention, participants gradually learned to ignore them during the learning process.

Summary: Research shows that primate ganglion cell responses to natural scenes are primarily driven by temporal variations in color and luminance caused by eye movements, with little influence from interaction with receptive field structure. Model predictions suggest that responses derive from the temporal pattern of stimulation from eye movements, reducing redundancy in the retinal signal. The magnocellular pathway is better suited to transmit detailed structure of natural scenes than the parvocellular pathway.

Summary: Many studies have shown a close relationship between anxiety disorders and attentional functioning, but the relationship between trait anxiety and attentional bias is still controversial. This study used materials from the International Affective Picture System to examine the effect of trait anxiety on attention to emotional stimuli over time. The results showed that trait anxiety has a significant temporal effect on attention to emotional stimuli, with increased attentional avoidance of threatening stimuli and a stronger attentional bias toward positive stimuli after 7 seconds.

Summary: This study compared the effects of different types of urban and rural landscape scenes on attention restoration using the Perceived Restorativeness Scale, perception complexity scoring, and eye tracking. The results showed that rural natural scenes had the highest restoration effect, and waterscapes and well-maintained vegetation were positively correlated with restorative benefits. Weeds and hardscapes were negatively correlated with restoration, possibly due to the maintenance of these typical elements. The harmony of elements with the environment was a key factor.

Summary: This study investigates how humans acquire meaningful understanding of the world with little supervision or semantic labels provided by the environment, emphasizing embodiment as a key component in the process. By training a deep reinforcement learning agent with high-dimensional visual observations in a 3D environment, the study shows the agent can learn stable representations of meaningful concepts without receiving any semantic labels. The results demonstrate the agent's ability to represent action-relevant information in a wide variety of sparse activation patterns extracted from a simulated camera stream, highlighting the strength of embodied learning over fully supervised approaches.

Summary: This article evaluates how multisensory cue combinations can improve the awareness of out-of-view objects in narrow field of view augmented reality displays. The results show that the Visual-Tactile combination leads to faster reactions compared to the Visual-Audio combination, indicating the usefulness of tactile transition cues. Additionally, visual and audio noise have a detrimental effect on performance when visual proximity cues are included.

Summary: Single-brain neuroimaging studies have shown that human cooperation is associated with neural activity in frontal and temporoparietal regions. However, it remains unclear whether single-brain studies are informative about cooperation in real life, where people interact dynamically. Such dynamic interactions have become the focus of interbrain studies. An advantageous technique in this regard is functional near-infrared spectroscopy (fNIRS) because it is less susceptible to movement artifacts than more conventional techniques like electroencephalography (EEG) or functional magnetic resonance imaging (fMRI). We conducted a systematic review and the first quantitative meta-analysis of fNIRS hyperscanning of cooperation, based on thirteen studies with 890 human participants. Overall, the meta-analysis revealed evidence of statistically significant interbrain synchrony while people were cooperating, with large overall effect sizes in both frontal and temporoparietal areas. All thirteen studies observed significant interbrain synchrony in the prefrontal cortex (PFC), suggesting that this region is particularly relevant for cooperative behavior. The consistency in these findings is unlikely to be because of task-related activations, given that the relevant studies used diverse cooperation tasks. Together, the present findings support the importance of interbrain synchronization of frontal and temporoparietal regions in interpersonal cooperation. Moreover, the present article highlights the usefulness of meta-analyses as a tool for discerning patterns in interbrain dynamics.

Summary: Accessing complex graphical information is critical for connecting blind and visually impaired individuals with the world. We developed three audio navigation interfaces that dynamically guide the user's hand to specific positions using audio feedback. Through usability testing and observation, we found that a voice-based navigation interface is the most effective and efficient in guiding blind individuals to their targets.

Summary: When performing visual tasks together, people coordinate their actions to divide labor and achieve group benefits. Information about each other's actions and performance can enhance action coordination and group benefits. Participants use external reference points to divide labor and are willing to forgo individual biases to boost group performance.
