Human conscious awareness is commonly seen as the climax of evolution. However, what function-if any-it serves in human behavior still debated. One leading suggestions that cardinal function to integrate numerous inputs-including multitude features and objects a complex scene-across different levels analysis into unified, coherent, meaningful perceptual experience. Here we demonstrate, however, integration with their background scenes can be achieved without either. We used binocular rivalry...
Predicting the timing of upcoming events enables efficient resource allocation and action preparation. Rhythmic streams, such as music, speech, biological motion, constitute a pervasive source for temporal predictions. Widely accepted entrainment theories postulate that rhythm-based predictions are mediated by synchronizing low-frequency neural oscillations to rhythm, indicated increased phase concentration (PC) activity rhythmic compared random streams. However, we show here PC enhancement...
Predicting the timing of upcoming events is critical for successful interaction in a dynamic world, and recognized as key computation attentional orienting. Temporal predictions can be formed when recent define rhythmic structure, well aperiodic streams or even isolation, specified interval known from previous exposure. However, whether these two contexts are mediated by common mechanism, distinct, context-dependent mechanisms, highly controversial. Moreover, although basal ganglia...
The amplitude envelope of speech is crucial for accurate comprehension. Considered a key stage in processing, the phase neural activity theta-delta bands (1-10 Hz) tracks during listening. However, mechanisms underlying this representation have been heavily debated. A dominant model posits that tracking reflects entrainment endogenous low-frequency oscillations to envelope. Alternatively, series evoked responses acoustic landmarks within It has proven challenging distinguish these two...
Exposure to rhythmic stimulation results in facilitated responses events that appear in-phase with the rhythm and modulation of anticipatory target-evoked brain activity, presumably reflecting "exogenous," unintentional temporal expectations. However, extent which this effect is independent from intentional processes not clear. In two EEG experiments, we isolated component high-level, factors. Visual targets were presented either or out-of-phase regularly flickering colored stimuli....
Neurophysiological studies in humans and nonhuman primates have revealed movement representations both the contralateral ipsilateral hemispheres. Inspired by clinical observations, we ask if this bilateral representation differs for left right Electrocorticography was recorded human participants during an instructed-delay reaching task, with movements produced either or arm. Using a cross-validated kinematic encoding model, found stronger hemisphere, effect that present preparation amplified...
Cerebellar degeneration disrupts modulation of EEG signatures attentional orienting in time.
A functional benefit of attention is to proactively enhance perceptual sensitivity in space and time. Although attentional orienting has traditionally been associated with cortico-thalamic networks, recent evidence shown that individuals cerebellar degeneration (CD) show a reduced reaction time from cues enable temporal anticipation. The present study examined whether the cerebellum contributes proactive modulation sensitivity. We tested CD participants on non-speeded, challenging...
Traditional associative learning tasks focus on the formation of associations between salient events and arbitrary stimuli that predict those events. This is exemplified in cerebellar-dependent delay eyeblink conditioning, where cues such as a tone or light act conditioned (CSs) aversive sensations at cornea (unconditioned stimulus [US]). Here, we ask if similar framework could be applied to another type sensorimotor – adaptation. Models adaptation posit introduction an environmental...
Human conscious awareness is commonly seen as the climax of evolution. However, what function – if any it serves in human behavior still debated. One leading suggestions holds that cardinal integration across numerous inputs and levels analysis including multitude features objects a complex scene into unified, coherent, meaningful perceptual experience. Here we demonstrate, however, their background scenes can be achieved without either. In group observers, incongruent were faster than...
Environmental rhythms potently drive predictive resource allocation in time, typically leading to perceptual and motor benefits for on-beat, relative off-beat, times, even if the rhythmic stream is not intentionally used. In two human EEG experiments, we investigated behavioral electrophysiological expressions of using direct resources away from on-beat times. This allowed us distinguish goal-directed attention automatic capture by rhythms. The following three conditions were compared: (1) a...
This study examined, using the Concealed Information paradigm, whether interstimulus intervals (ISI) typically used for electrodermal measurement can be shortened. An ISI ranging from 16 s to 24 (with a mean of 20 s) was compared with an shortened by 50% within-participants design. It demonstrated that this shortening had no effect on differential skin conductance responses personally significant details and nearly identical detection efficiency observed under 2 ISIs. However, overall were...
Intending to perform an action and then immediately executing it is a mundane process. The cognitive neural mechanisms involved in this process of "proximal" intention formation execution, the face multiple options choose from, are not clear, however. Especially, clear how intentions formed when choice makes no difference. Here we used behavioral electrophysiological measures investigate temporal dynamics proximal "change intention" free picking scenario, which alternatives on par for...
Errors that result from a mismatch between predicted movement outcomes and sensory afference are used to correct ongoing movements through feedback control adapt feedforward of future movements. The cerebellum has been identified as critical part the neural circuit underlying implicit adaptation across wide variety (reaching, gait, eye movements, speech). contribution this structure is less well understood. Although it recently shown in speech domain individuals with cerebellar degeneration...
We examined whether the Concealed Information Test (CIT) may be used when critical details are unavailable to investigators (the Searching CIT [SCIT]). This use have important applications in criminal investigations (e.g., finding location of a murder weapon) and security-related threats detecting individuals groups suspected planning terror attack). Two classes algorithms designed detect items classify SCIT were examined. The 1st class was based on averaging responses across subjects...
Summary The Concealed Information Test (CIT) aims to detect concealed information through differential physiological and behavioral responses the items. Although extensive experimental research has demonstrated empirical validity of CIT, external these studies been questioned. One essential difference between setups realistic contexts is voluntary act committing crime concealing critical (crime‐related) present study examined whether detection efficiency CIT alters under conditions free...
Considerable evidence suggests that subliminal information can trigger cognitive and neural processes. Here, we examined whether elicitation of orienting response by personally significant (PS) verbal requires conscious awareness the input. Subjects were exposed to Concealed Information Test (CIT), in which autonomic responses for autobiographical items are typically larger than control items. These presented subliminally using two different masking protocols: single or multiple presentation...
This study focused on the application of Concealed Information Test (CIT) to situations in which crime-related information is shared by a group suspects but not available investigators (a method known as "searching CIT," or SCIT). Twenty-two groups, each comprising 4 7 participants (115 total), planned 1 2 mock crimes (kidnapping bank robbery). While planning crime, decided 5 critical items (e.g., city was located). Each item chosen from predefined set alternatives. At second stage, SCIT...
