A multitude of studies demonstrate that self-relevant stimuli influence attention. Self-owned objects are a special class stimuli. If self-owned object can indeed be characterised as stimulus then, consistent with theoretical predictions, behavioural effect ownership on attention should present. To test this prediction, task was selected is known to particularly sensitive measure the prioritisation visual information: temporal order judgement. Participants completed judgements pictures "own"...
Despite decades of research, the conditions under which shifts attention to prior target locations are facilitated or inhibited remain unknown. This ambiguity is a product popular feature discrimination task, in attentional bias commonly inferred from efficiency by stimulus discriminated after its location has been repeated changed. Problematically, these tasks lead integration effects; effects target-location repetition appear depend entirely on whether response also repeats, allowing for...
Vision is crucial for many everyday activities, but the mind not always focused on what eyes see. Mind wandering occurs frequently and associated with attenuated visual cognitive processing of external information. Corresponding changes in gaze behavior—namely, fewer, longer, more dispersed fixations—suggest a shift how system samples Using three computational models salience two innovative approaches measuring semantic informativeness, current work assessed whether these reflect prioritizes...
Human perception and action rely on a fundamental binding mechanism that forges integrated event representations from distributed features. Encountering any one of these features later can retrieve the whole event, thus expediting cognitive processing. The traditional view confines it to successful episodes, holding human system does not leverage errors for optimizing corresponding representations. Here we use sequential analyses erroneous episodes explore whether promotes future behavior...
In stimulus identification tasks, and response, location response information, is thought to become integrated into a common event representation following response. Evidence for this feature integration comes from paradigms requiring keypress responses pairs of sequentially presented stimuli. such paradigms, there robust cost when target only partially matches the preceding representation. This known as partial repetition cost. Notably, however, these experiments rely on discrimination...
Attentional effects are often inferred from keypress reaction time (RT) studies when two sequentially presented stimuli, appearing at the same location, generate costs or benefits. The universality of these attentional attributions is challenged by data perceptual discrimination tasks, which reveal that location repetition benefits and depend on whether a prior response repeats switches, respectively. According to dual-stage accounts, post-attentional may be abolished making responses in...
Action selection is thought to involve of the action's sensory outcomes. This notion supported when encountering a distractor that resembles learned response-outcome biases response selection. Some evidence, however, suggests larger contribution stimulus-based leaves little role for outcome-based selection, especially in forced-choice tasks with easily identifiable target stimuli. In present study, we asked whether depends on ease and efficiency If so, then efficient should reduce impact an...
Purpose Marksmanship data is a staple of military and law enforcement evaluations. This ubiquitous nature creates critical need to use all relevant information convey outcomes in meaningful way for the end users. The purpose this study demonstrate how simple simulation techniques can improve interpretations marksmanship data. Design/methodology/approach uses three simulations advantages small arms combat modeling, including (1) benefits incorporating Markov Chain into Monte Carlo shooting...
Stress can impact perception, especially during use-of-force. Research efforts thus advance both theory and practice by examining how perception use-of-force might drive behavior. The current study explored the relationship between perceptual judgments performance novel close-combat training. Analyses included from assessments conducted pre-training post-training that required realistic decisions in addition to an artificially construed stress-inoculation event used as a training exercise....
Abstract Judgments of the present visual world are affected by what came before. When judgments properties such as orientation biased in direction preceding stimuli, this is called serial dependence. Visual dependence thought to arise from mechanisms that support perceptual continuity: because physical an object usually vary smoothly time, perception might be accurately stabilized smoothing perceived features time. However, continuity should object-specific, one more related its own past...
Covert spatial cueing effects refer to the finding that targets appearing in location of a previous cue stimulus are typically responded more rapidly than at different locations cue. One explanation these is captures attention, so attention already target when appears, resulting faster responses relative appear an uncued new requires shift attention. Here, however, we investigate possibility relationship between cues and complicated just repetition by viewing as separate event files which...
Consider a paradigm in which visual stimulus is first presented and then feature of that appears as either target or distractor subsequent search task. It has been shown if response made to the initial appearance stimulus, validity effect found; times are faster when part than it distractor. This disappears withheld stimulus. Our study demonstrates there an inverse effect. First, like previous studies, we replicated was responded to. Second, unlike not to, four experiments consistently...
