The ability to attend someone else's gaze is thought represent one of the essential building blocks human sociocognitive system. This behavior, termed social attention, has traditionally been assessed using laboratory procedures in which participants' response time and/or accuracy performance indexes attentional function. Recently, a parallel body emerging research started examine attention during real life interactions naturalistic and observational methodologies. main goal present work was...
Numerous studies conducted within the recent decades have utilized Posner cuing paradigm for eliciting, measuring, and theoretically characterizing attentional orienting. However, data from suggest that task might not provide an unambiguous measure of attention, as reflexive spatial orienting has been found to interact with extraneous processes engaged by task's typical structure, i.e., probability target presence across trials, which affects tonic alertness, voluntary temporal preparation....
Abstract Gaze following is a fundamental ability that plays an important role in human social function. However, the link between these two processes remains elusive. On one hand, typically developing persons show robust gaze laboratory cuing tasks. other investigations with individuals autism suggest reduced competence this population may partly reflect atypical access to information through attending perceptual changes normally accompany shifts, like luminance or motion transients. Here we...
Human social behavior is fine-tuned by interactions between individuals and their environments. Here we show that motivation plays an important role in this process. Using a novel manipulation of reward included elements real-life exchanges, demonstrate the emergence attentional orienting for coincidental spatial associations received positive reward. After interaction with experimenter, participants completed computerized task which they positive, negative, or no performance to spatially...
Abstract Previous research has shown that the prenatal environment, commonly indexed by birth weight (BW), is a predictor of morphological brain development. We previously showed in monozygotic (MZ) twins associations between BW and morphology were independent genetics. In present study, we employed longitudinal MZ twin design to investigate whether variations environment (as discordance BW) are associated with resting‐state functional connectivity (rs‐FC) structural connectivity. focused on...
Anxiety impacts performance monitoring, though theory and past research are split on how for whom. However, has often examined either trait anxiety in isolation or task-dependent state indexed event-related potential components, such as the error-related negativity post-error positivity (Pe), calculated at a single node during limited window of time. We introduced 2 key novelties to this electroencephalography examine link between monitoring: (i) we manipulated antecedent, task-independent,...
In the real world, we often fail to notice changes in our environment. some cases, such as not noticing a car moving into lane, results can be catastrophic. This so-called change blindness has been seen experimentally both through failing images on-screen well other people's identity. However, less is known regarding how manifests virtual settings varying visual clutter or with types of interaction someone prior change. Across two studies (n = 134), participants engaged an online video chat...
Abstract Prior work suggests that individuals with an eating disorder demonstrate task-based and overall differences in sociocognitive functioning. However, the majority of studies assessed specifically anorexia nervosa often employed a single experimental paradigm, providing piecemeal understanding applicability various lab tasks denoting meaningful across diverse individuals. The current study was designed to address these outstanding issues. Participants were undergraduate females who...
Attention is engaged differently depending on the type and utility of an attentional cue. Some cues like visual transients or social gaze engage attention effortlessly. Others symbols geometric shapes require task-relevant deliberate processing. In laboratory, these effects are often measured using a cuing procedure, which typically manipulates cue its for task. Recent research however has uncovered that in addition to spatial orienting, this popular paradigm also engages two additional...
Cognitive psychology considers the environment as providing information, not affecting fundamental information processes. Thus, cognitive psychology's traditional paradigms study responses to precisely timed stimuli in controlled environments. However, new research demonstrates does influence processes and offers methods. The authors examine one such proposal: ethology. ethology improves ecological validity through first drawing inspiration from robust phenomena real world, then moving into...
While it is widely accepted that the single gaze of another person elicits shifts attention, there limited work on effects multiple gazes despite real-world social cues often occurring in groups. Further, less known regarding role unequal reliability varying and nonsocial information attention. We addressed these gaps by employing a variant cueing paradigm, simultaneously presenting participants with three faces. Block-wise, we manipulated whether one face (Identity condition) or location...
Social interactions are crucial to successfully navigate daily life, and the presence of others can influence attention. With increases in online interactions, we investigated whether implied social (e.g., visual depiction a fictitious player) instructing participants cooperate or compete) affects attention virtual settings. Participants completed search task were either told they completing alone (controls) cooperating/competing with another. Competition instructions led faster but less...
A wealth of recent research indicates that rewarded singletons capture attention. However, it is unclear whether reward may also lead to the development spatial associations between neutral cues and corresponding target locations, resulting in orienting. Furthermore, reward-mediated has mostly been demonstrated using monetary reward, opening up possibility this finding not generalize other types rewards. To test this, we used a social examined performance Baseline, Learning, Test conditions....
Top-down attentional control can bias visual short-term memory (VSTM), such that “retro-cues”, cues presented after a stimulus array, improve for cued items. Less is known, however, about whether different aspects of stimulus, as its identity or spatial location, are also affected by top-down attention. Here we investigated the effect attention on VSTM object type and location. Further, based prior research suggesting link between subthreshold autism traits working impairments, administered...
