Sharing numerous characteristics with suppression in the other senses, tactile suppression is a reliable phenomenon that accompanies movement. By investigating the simplest of movements (e.g., finger flexions), early research tried to explain the origins of the phenomenon in terms of motor command generation together with sensory reafference. Here,...

As we look at the world around us, we make numerous eye-movements, or saccades, toward objects of interest. These eye-movements are rapid/ballistic and most of the time we do not even notice them, not to mention that we are very rarely concerned with their having taken place. Interestingly, convincing psychophysical demonstrations have shown that r...

We report four experiments on the speed of people's reactions to sensory stimulation while throwing and catching a basketball. Thirty participants participated in Experiment 1, split according to basketball expertise: none, intermediate (6years on average), or advanced (20years or more). The participants had to catch a bouncing basketball. The move...

Tactile perception is inhibited during movement execution, a phenomenon known as tactile suppression. Here, we investigated whether the type of movement determines whether or not this form of sensory suppression occurs. Participants performed simple reaching or exploratory movements. Tactile discrimination thresholds were calculated for vibratory s...

We investigated tactile perception during the execution of self- versus externally-generated movements. In a first experiment, we established the temporal characteristics of the movements of interest. In a second experiment, participants had to try to detect a short gap in an otherwise continuous vibratory stimulus delivered to their right wrist un...

According to “The World Health Organization”, obesity during childhood is directly associated with multiple complications and with an increased risk of the installation of various pathologies. Considering the increase in this pathology among children and teenagers, new instruments of prevention are needed. Virtual reality is an innovative tool that...

Rounded shapes are associated with softness and warmth, whereas Platonic solids are associated with hardness and coldness. We investigated the temperature-shape association through sensorial/conceptual qualities of geometric ice-like textured shapes. In Experiment 1, participants viewed symmetrical rotating 3D shapes (five Platonic solids-cube, tet...

This study examined the determinants of sustained physical activity. Eighty-four participants undertook a 7-weeks walking regime (i.e., a 1-h biometrically-monitored walk, at least 5 days/week), with bioelectrical impedance (BIA) and total cholesterol capillary blood measurements performed before and after programme. To investigate behavioural habi...

In the last decade, a number of studies conducted with preschoolers interacting with social robots suggest positive effects on foreign language learning, attitudes towards technology, and the recognition of geometrical shapes and colours. However, the effects of similar interactions for the improvement of mother tongue acquisition among children ar...

Rounded shapes, which have been shown to enhance sweetness, were compared to the perfectly symmetrical Platonic solids. In a first online experiment, participants were presented with a rotating three-dimensional geometric shape (a sphere, the five Platonic solids, and three irregular angular/rounded/naturalistic controls), and indicated their likin...

We present two online experiments investigating trust in artificial intelligence (AI) as a primary and secondary medical diagnosis tool and one experiment testing two methods to increase trust in AI. Participants in Experiment 1 read hypothetical scenarios of low and high-risk diseases, followed by two sequential diagnoses, and estimated their trus...

Considering the wealth of recent studies on affective touch, to date, little research addressed the role of the other sensory modalities in the modulation of hedonic tactile perception. Here, we investigated the behavioral and electrodermal signature of the interaction between simultaneously presented visual and tactile stimuli. In three experiment...

Tactile sensitivity measured on the hand is significantly decreased for a moving (MH), as opposed to a resting hand (RH). This process (i.e., tactile suppression) is affected by the availability of visual information during goal-directed action. However, the timing of the contribution of visual information is currently unclear for reach-to-grasp mo...

In recent years, a number of commentators have suggested that the use of finings to clarify beer can impair the flavour, because of the removal of key volatile aromatic molecules from the drink. However, are such claims necessarily correct? Unaware of any previous attempt to address this question empirically, we conducted both a blind and a sighted...

Slurping (e.g., as when consuming a hot liquid such as soup) is a common practice in many parts of Asia. The practice is also encouraged amongst many professional wine and coffee tasters in order to help enhance the release of volatile aromas. Would slurping enhance flavour perception in western participants (regular consumers) too, and/or simply m...

Emotional processes have an impact on the anticipation and perception of bodily threat sensations, such as breathlessness. However, little is known about the reverse influence of breathlessness on emotional processes, as well as its modulation by anxiety sensitivity (AS). Here, we investigated by means of visually evoked potentials how the percepti...

Fear is elicited by imminent threat and leads to phasic fear responses with selective attention, whereas anxiety is characterized by a sustained state of heightened vigilance due to uncertain danger. In the present study, we investigated attention mechanisms in fear and anxiety by adapting the NPU-threat test to measure steady-state visual evoked p...

Tactile information is differentially processed over the various phases of goal-directed movements. Here, event-related potentials (ERPs) were used to investigate the neural correlates of tactile and visual information processing during movement. Participants performed goal-directed reaches for an object placed centrally on the table in front of th...

We report two naturalistic citizen science experiments designed to highlight the influence of the texture of plateware on people’s rating of the mouthfeel and taste of food (specifically, biscuits) sampled from that plateware. In the first experiment, participants tasted a biscuit from a pair of plates, one having a rough and the other a smooth fin...

It has been suggested that incongruence between signals for motor intention and sensory input can cause pain and other sensory abnormalities. This claim is supported by reports that moving in an environment of induced sensorimotor conflict leads to elevated pain and sensory symptoms in those with certain painful conditions. Similar procedures can l...

We report three online experiments designed to investigate how the visual presentation of a dish influences people’s rating of exactly the same ingredients. For this, participants were visually presented with two dishes, each containing the same ingredients arranged in either a linear or circular presentation. The influence of different naming stra...

In the present study, we investigated whether indenting the sides of novel objects (e.g., product packaging) would influence where people grasp, and hence focus their gaze, under the assumption that gaze precedes grasping. In Experiment 1, the participants grasped a selection of custom-made objects designed to resemble typical packaging forms with...

Repetitive transcranial magnetic stimulation (rTMS) of the posterior parietal cortex (PPC) at frequencies lower than 5 Hz transiently inhibits the stimulated area. In healthy participants, such a protocol can induce a transient attentional bias to the visual hemifield ipsilateral to the stimulated hemisphere. This bias might be due to a relatively...

Repetitive transcranial magnetic stimulation (rTMS) in ‘offline’ experiments is commonly administered to participants that are in a relaxed ’resting state’. Clearly, this approach leads to an ill controlled baseline state of the participants’ brain, in face of evidence that the mental baseline influences how the brain is affected by TMS (e.g., Silv...

Tactile perception is often impaired during movement. The present study investigated whether such sensory suppression also occurs during back movements, and whether this would be modulated by attention. In two tactile detection experiments, participants simultaneously engaged in a movement task, in which they executed a back-bending movement, and a...

Tactile information arriving at our sensory receptors is differentially processed over the various temporal phases of goal-directed movements. By using event-related potentials (ERPs), we investigated the neuronal correlates of tactile information processing during movement. Participants performed goal-directed reaches for an object placed centrall...

Tactile perception is inhibited during goal-directed reaching movements (sensory suppression). Here, participants performed simple reaching or exploratory movements (where contact with the table surface was maintained). We measured tactile discrimination thresholds for vibratory stimuli delivered to participants' wrists while executing the movement...

Reaching with the hand is characterized by a decrease in sensitivity to tactile stimuli presented to the moving hand. Here, we investigated whether tactile suppression can be canceled by attentional orienting. In a first experiment, participants performed a dual-task involving a goal-directed movement paired with the speeded detection of a tactile...

Goal-directed movements are characterized by sensory suppression, that is, by decreased sensitivity to tactile stimuli. In the present study, we investigated tactile suppression during movement using a complex motor task: basic 3-ball juggling. It was hypothesized that a decrease in tactile sensitivity would be observed, together with a shift in pa...

We report three experiments designed to investigate changes in tactile sensitivity over the time-course of goal-directed movements. A dual-task paradigm involving a speeded movement task and a non-speeded perceptual task was utilized. In the movement task, participants grasped a start computer mouse with their right hand (RH) and, at the go signal,...

We present two experiments in which we investigated whether tactile attention is modulated by action preparation. In Experiment 1, participants prepared a saccade toward either the left or right index finger, depending on the pitch of a non-predictive auditory cue. In Experiment 2, participants prepared to lift the left or right index finger in res...
