Traditionally, objects of attention are characterized either as full-fledged entities or elements grouped by Gestalt principles. Because humans appear to use social groups units explain activities, we proposed that a socially defined group, according interaction information, would also be possible object attentional selection. This hypothesis was examined using displays with and without handshaking interactions. Results demonstrated object-based attention, which measured an object-specific...

Abstract Human vision supports social perception by efficiently detecting agents and extracting rich information about their actions, goals, intentions. Here, we explore the cognitive architecture of perceived animacy constructing Bayesian models that integrate domain‐specific hypotheses agency with domain‐general constraints on sensory, memory, attentional processing. Our model posits combines a bottom–up, feature‐based, parallel search for goal‐directed movements top–down selection process...

Understanding actions plays an impressive role in our social life. Such processing has been suggested to be reflected by EEG Mu rhythm (8-13 Hz sensorimotor regions). However, it remains unclear whether is modulated the nature of coordination information interactive (i.e., inter-dependency). This study used a novel manipulation information: computer-based task, participants viewed replay two chasers chasing common target coordinately (coordinated chase) or independently (solo chase)....

Although our world is hierarchically organized, the perception, attention, and memory of hierarchical structures remain largely unknown. The current study shows how a motion representation enhances inference an object's position in dynamic display. hierarchy formed as acyclic tree which each node represents distinctive component. Each individual object instantiated tree. In task, participants were asked to infer target object, given it moved jointly with other objects. results showed that...

The present study investigated whether visual working memory (VWM) functions as a few (about 3 ∼ 4) fixed slots by examining how the distribution of VWM is adjusted. Adopting change-detection paradigm, we required subjects to memorize four items, one which was prioritized. If 4 slots, allocating multiple prioritized item would leave no slot for some other items; consequently information be stored them, leading substantial decrease in performance matter small or large changes occurred. result...

Abstract Representing the mental state of partner lays foundation for successful social interaction. While representation group members has been extensively studied, it is unclear how intergroup interactions affect it. In three experiments utilizing joint flanker task, we found that competition between groups brought about a greater effect (Experiment 1). Such phenomenon was not due to per se, as occurred individuals from different did enhance 2). Using minimal grouping method directly...

Human vision is remarkably good at recovering the latent hierarchical structure of dynamic scenes. Here, we explore how visual attention operates with this motion representation. The way in which responds to surface physical features has been extensively explored. However, know little about distribution can be distorted by structure. To topic, conducted two experiments investigate relationship between minimal graph distance (MGD), one key factor representation, and attentional distribution....

Comprehensive understanding of visual scenes necessitates grasping the relations among objects. Given potentially pivotal role working memory (VWM) in processing relations, it is important to investigate representation VWM. In our previous study, we proposed integrated storage hypothesis, postulating that and objects are stored together as an structured The present study aimed test this hypothesis against alternative separate encoding by probing irrelevant-distracting effect. Across three...

Visual sensory memory constructs representations of the physical information visual objects. However, few studies have investigated whether abstract information, such as semantic is also involved in these representations. This study utilized a masking technique combined with partial report paradigm to examine representation contains information. Here, we regarded concept orientation carried by stimulus In three experiments, participants were asked remember arrows. stimuli (triangles,...

Visual working memory (VWM) has been traditionally viewed as a mental structure subsequent to visual perception that stores the final output of perceptual processing. However, VWM recently emphasized critical component online perception, providing storage for intermediate representations produced during This interactive view holds core assumption is not terminus processing; stored information rather continues undergo processing if necessary. The current study tests this assumption,...

Selective attention toward the target in visual search has been extensively studied, but little is known about selection process and role of non-target. However, daily life scenes often contain a large number interrelated items, focusing on non-target not only common also helpful for locating target. Here we explore this three experiments which participants searched among regularly or randomly arranged numbers. Results showed that human used regularity sequence to shorten time. Reaction time...

Previous research has indicated that children perceive social category members as having intrinsic obligations toward each other, which shape their expectations for interactions. However, it is unclear whether teenagers (aged 13 to 15) and young adults 19 21) continue hold such beliefs, given increased experience with group dynamics external rules. To explore this question, three experiments were conducted a total of 360 participants (N = 180 age group). Experiment 1 examined negative...

Previous research suggests that belief in free will is related to intention perception, one of the most fundamental processes social perception and cognition. However, this has not been able distinguish between differences sensitivity response bias. Here, we used a chasing detection task allowed us investigate whether individuals who believe more are better at detecting intentionality cues (sensitivity) or instead prone see such even when they there (bias). In addition, measured three...

Handling imperfect information problems is fundamental to perception, learning, and decision-making. Ensemble perception may partially overcome by providing global clues. However, if not all cluster elements are readily accessible, the observations required for computing statistics incomplete. In this case, these elements' internal correlations (i.e., regularity) could serve as clues elucidate missing pieces. We thus investigated spatial regularity's role in ensemble under situations created...

Agents are not omnipotent. Instead, their motions driven by both internal intentions and outside constraints (such as an impulsive dog resisting its leash). In many cases, agents even pulled away from goals. How does vision interpret such intention-motion dissociations? One answer is that it simply can't, suggested studies showing has little tolerance for deviations perfect goal-directed (e.g. Gao et al., 2009). Alternatively, can detect deviated motions, provided explain causal imposed the...

A visual scene can be recursively parsed into parts and sub-parts. We present a causal model of parsing that synthesize identify parse trees, predict perceptual complexity, pass (limited) Turing test. It describes the process generating as splitting it with vertical horizontal cuts, modulated by two parameters: (a) Splitting Factor (SF) – large SF favors part more sub-parts, wide shallow tree; (b) Part Similarity (PS) PS evenly Given scene, infers best tree evaluating number their...
