Touch Can Be as Accurate as Passively-Guided Kinaesthesis in Length Perception
Publisher: Brill
Date: 2013
DOI: 10.1163/22134808-00002428
Abstract: Two experiments were designed to investigate the contribution of touch and kinaesthesis to haptic perception of the length of raised lines. Experiment 1 showed that judgements based on kinaesthetic information were not more accurate than those based on cutaneous information. Instead, kinaesthetic and cutaneous inputs appear to be weighted almost equally in the haptic percept, with haptic performance more closely approximated by cutaneous performance than by kinaesthetic. In Experiment 2 it was shown that effects attributed to condition (modality) were not due to the speed with which the stimulus or exploring finger moved. Our results challenge the view that kinaesthesis is more important than touch for identification of raised line drawings.

Can you tickle yourself if you swap bodies with someone else?
Publisher: Elsevier BV
Date: 2014
DOI: 10.1016/J.CONCOG.2013.10.009
Abstract: The effect of the body transfer illusion on the perceived strength of self- and externally-generated "tickle" sensations was investigated. As expected, externally generated movement produced significantly higher ratings of tickliness than those associated with self-generated movements. Surprisingly, the body transfer illusion had no influence on the ratings of tickliness, suggesting that highly surprising, and therefore hard to predict, experiences of body image and first-person perspective do not abolish the attenuation of tickle sensations. In addition, evidence was found that a version of the rubber hand illusion exists within the body transfer illusion. We situate our findings within the larger debate over sensory attenuation: (1) there is an attenuation of prediction errors that depends upon the context in which sensory input is predicted (i.e., efference copy), and (2) sensory attenuation is a necessary consequence of self-generated movement irrespective of context (i.e., active inference). The results support the notion of active inference.

Exposure factors of Victoria's active motorcycle fleet related to serious injury crash risk
Publisher: Informa UK Limited
Date: 10-09-2016
DOI: 10.1080/15389588.2016.1159304
Abstract: The purpose of this study was to describe the nature and extent of current powered 2-wheeler (PTW) risk exposures in order to support future efforts to improve safety for this mode of transport. A cross-sectional analysis of the control arm of a population-based case-control study was conducted. The control s le was selected from 204 sites on public roads within 150 km of the city of Melbourne that were locations of recent serious injury motorcycle crashes. Traffic observations and measurements at each site were s led for a mean of 2 h on the same type of day (weekday, Saturday, or Sunday) and within 1 h of the crash time. Photographs of passing riders during this observation period recorded data relating to characteristics of PTWs, age of riders, travel speed of PTWs and all vehicles, time gaps between vehicles, visibility, and protective clothing use. Motorcycles and scooters represented 0.6% of all traffic (compared with 4% of all vehicle registrations). Riders were significantly more likely to have larger time gaps in front and behind when compared to other vehicles. The average travel speed of motorcycles was not significantly different than the traffic, but a significantly greater proportion were exceeding the speed limit when compared to other vehicles (6 vs. 3%, respectively). The age of registered owners of passing motorcycles was 42 years. Over half of riders were wearing dark clothing with no fluorescent or reflective surfaces. One third of motorcyclists had maximum coverage of motorcycle-specific protective clothing. A very low prevalence of motorcyclists combined with relatively higher rates of larger time gaps to other vehicles around motorcycles may help explain their overrepresentation in injury crashes where another vehicle fails to give way. An increased risk of injury in the event of a crash exists for a small but greater proportion of motorcyclists (compared to other vehicle types) who were exceeding the speed limit. An apparent shift toward older age of the active rider population may be reducing injury crash risk relative to exposure time. There is significant scope to improve the physical conspicuity of motorcyclists and the frequency of motorcycle specific protective clothing use. These results can be used to inform policy development and monitor progress of current and future road safety initiatives.

MCTP system model based on linear programming optimization of apertures obtained from sequencing patient image data maps
Publisher: Wiley
Date: 31-07-2014
DOI: 10.1118/1.4890602
Abstract: The authors present a hybrid direct multileaf collimator (MLC) aperture optimization model exclusively based on sequencing of patient imaging data to be implemented on a Monte Carlo treatment planning system (MC-TPS) to allow the explicit radiation transport simulation of advanced radiotherapy treatments with optimal results in efficient times for clinical practice. The planning system (called CARMEN) is a full MC-TPS, controlled through aMATLAB interface, which is based on the sequencing of a novel map, called "biophysical" map, which is generated from enhanced image data of patients to achieve a set of segments actually deliverable. In order to reduce the required computation time, the conventional fluence map has been replaced by the biophysical map which is sequenced to provide direct apertures that will later be weighted by means of an optimization algorithm based on linear programming. A ray-casting algorithm throughout the patient CT assembles information about the found structures, the mass thickness crossed, as well as PET values. Data are recorded to generate a biophysical map for each gantry angle. These maps are the input files for a home-made sequencer developed to take into account the interactions of photons and electrons with the MLC. For each linac (Axesse of Elekta and Primus of Siemens) and energy beam studied (6, 9, 12, 15 MeV and 6 MV), phase space files were simulated with the EGSnrc/BEAMnrc code. The dose calculation in patient was carried out with the BEAMDOSE code. This code is a modified version of EGSnrc/DOSXYZnrc able to calculate the beamlet dose in order to combine them with different weights during the optimization process. Three complex radiotherapy treatments were selected to check the reliability of CARMEN in situations where the MC calculation can offer an added value: A head-and-neck case (Case I) with three targets delineated on PET/CT images and a demanding dose-escalation a partial breast irradiation case (Case II) solved with photon and electron modulated beams (IMRT + MERT) and a prostatic bed case (Case III) with a pronounced concave-shaped PTV by using volumetric modulated arc therapy. In the three cases, the required target prescription doses and constraints on organs at risk were fulfilled in a short enough time to allow routine clinical implementation. The quality assurance protocol followed to check CARMEN system showed a high agreement with the experimental measurements. A Monte Carlo treatment planning model exclusively based on maps performed from patient imaging data has been presented. The sequencing of these maps allows obtaining deliverable apertures which are weighted for modulation under a linear programming formulation. The model is able to solve complex radiotherapy treatments with high accuracy in an efficient computation time.

Direct comparison of the haptic and visual horizontal–vertical illusions using traditional figures and single lines
Publisher: Brill
Date: 2012
Abstract: The horizontal–vertical illusion (HVI) has been widely and extensively reported as a visual phenomenon in which a vertical line is perceived as shorter than a horizontal line of the same length. Like a number of geometric illusions, the HVI has also been found to occur haptically, though there is less agreement in the literature as to the extent and direction of the illusion. The relatively small number of haptic HVI papers coupled with a variety of stimuli and procedures used make it difficult to make direct comparison between the visual and haptic versions of the illusion. After a brief critical literature review, the current paper reports a study in which the visual and haptic HVIs are directly compared. In a bid to reconcile previous shortcomings, three sets of stimuli were used: L-figures, inverted T-figures, and separated horizontal and vertical lines. The stimuli were presented in two lengths: 3 and 9 cm. The dependent variable was percentage error between the horizontal and vertical — no error represents an absence of illusion. As expected, inverted T-figures produced an illusion significantly stronger than both the L-figures and single lines, which in turn did not differ from each other. Further, the illusion was present to the same extent in both modalities. Stimuli of 9 cm produced relatively stronger illusions than those that measured 3 cm, and stimulus size interacted with modality. The consequences of these findings for earlier research and proffered suggestions as to what causes this and other illusions are discussed.

Dose painting by means of Monte Carlo treatment planning at the voxel level
Publisher: Elsevier BV
Date: 10-2017
DOI: 10.1016/J.EJMP.2017.04.005
Abstract: To develop a new optimization algorithm to carry out true dose painting by numbers (DPBN) planning based on full Monte Carlo (MC) calculation. Four configurations with different clustering of the voxel values from PET data were proposed. An optimization method at the voxel level under Lineal Programming (LP) formulation was used for an inverse planning and implemented in CARMEN, an in-house Monte Carlo treatment planning system. Beamlet solutions fulfilled the objectives and did not show significant differences between the different configurations. More differences were observed between the segment solutions. The plan for the dose prescription map without clustering was the better solution. LP optimization at voxel level without dose-volume restrictions can carry out true DPBN planning with the MC accuracy.

Active and Passive Movements Give Rise to Different Judgments of Coldness
Publisher: SAGE Publications
Date: 04-2006
DOI: 10.1068/P5439
Abstract: When the right index fingertip of twelve subjects was moved across a cold (15°C) tile by a machine (passive-guided condition), the subjects rated the temperature of the tile as being colder than when they moved the finger across the stimulus themselves (active condition). Results confirmed that active movements were associated with an attenuation of ‘coldness’. When these findings are considered alongside those of earlier experiments (see VanDoorn et al, 2005 Perception34 231–236), it may be concluded that intentionality of movement plays some role in this attenuation.
Raised Line Drawings are Spontaneously Explored with a Single Finger
Publisher: SAGE Publications
Date: 05-2000
DOI: 10.1068/P2964
Abstract: In this study we examine the strategies used by blindfolded subjects asked to freely explore raised line drawings and identify what is depicted in them. We were particularly interested in how often a single finger is spontaneously used because in several studies subjects are forced to use only one fingertip and the extent to which this restriction may depress haptic perception is unclear. The results suggest that despite a variety of strategies, people ‘naturally’ use single fingertips sufficiently often to allow confidence in conclusions that are based on studies imposing this restriction.

Capture of kinesthesis by a competing cutaneous input
Publisher: Springer Science and Business Media LLC
Date: 03-06-2012
DOI: 10.3758/S13414-012-0327-7
Abstract: In four experiments, blindfolded participants were presented with pairs of stimuli simultaneously, one to each index finger. Participants moved one index finger, which was presented with cutaneous and/or kinesthetic stimuli, and this movement caused a raised line to move underneath the other, stationary index finger in a yoked manner. The stimuli were 180º rotations of each other (e.g., ), and thus when a to be felt at the stationary finger. When asked to report the experience, participants predominantly reported the cutaneous stimulus, seemingly being ignorant of the kinesthetic stimulus. This appears to be an intrahaptic capture phenomenon, which is of interest because it suggests that conflict between intrahaptic sensory stimuli can go unnoticed sometimes we are unaware of how we moved, and sometimes we do not know what we touched. The results are interpreted in light of optimal integration, perceptual suppression, reafference suppression, and inattentional blindness.

The TDS: a new device for comparing active and passive-guided touch
Publisher: Institute of Electrical and Electronics Engineers (IEEE)
Date: 2000
DOI: 10.1109/86.867883
Abstract: A problem when comparing active and passive tactile perception of two-dimensional (2-D) stimuli is matching the active and passive tasks on all variables except the one of interest--active versus passive touch. A new computer-controlled device--the tactile display system (TDS)--has been developed to deal with this problem. The TDS tracks an "active" subject's fingertip movements during exploration of a raised line drawing and digitally records this spatio-temporal information. It then guides a passive participant's fingertip over the same path, matching for location and speed. Any difference in performance can thus be attributed to the different conditions (active versus passive) because other variables are held constant.

Measuring teamwork performance: Validity testing of the Team Emergency Assessment Measure (TEAM) with clinical resuscitation teams
Publisher: Elsevier BV

DOI: 10.1016/J.RESUSCITATION.2016.01.026
Abstract: To test the resuscitation non-technical Team Emergency Assessment Measure (TEAM) for feasibility, validity and reliability, in two Australian Emergency Departments (ED). Non-technical (teamwork) skills have been identified as inadequate and as such have a significant impact on patient safety. Valid and reliable teamwork assessment tools are an important element of performance assessment and debriefing processes. A quasi experimental design based on observational ratings of resuscitation non-technical skills in two metropolitan ED. Senior nursing staff rated 106 adult resuscitation team events over a ten month period where three or more resuscitation team members attended. Resuscitation events, team performance and validity and reliability data was collected for the TEAM. Most rated events were for full cardiac resuscitation (43%) with 3-15 team members present for an average of 45 min. The TEAM was found to be feasible and quickly completed with minimal or no training. Discriminant validity was good as was internal consistency with a Cronbach alpha of 0.94. Uni-dimensional and concurrent validity also reached acceptable standards, 0.94 and >0.63 (p=<0.001), respectively, and a single 'teamwork' construct was identified. Non-technical skills overall were good but leadership was rated notably lower than task and teamwork performance indicating a need for leadership training. The TEAM is a feasible, valid and reliable non-technical assessment measure in simulated and real clinical settings. Emergency teams need to develop leadership skills through training and reflective debriefing.

Intrasensory Attention: Kinaesthetic versus Cutaneous Inputs
Publisher: SAGE Publications
Date: 06-2007
DOI: 10.1068/P5690
Abstract: Blindfolded participants felt pairs of raised-line drawings simultaneously, one with each index finger. The stimuli presented at each fingertip were 180° rotations of each other (eg 6 and 9). One finger moved (either actively or passively), and this in turn caused movement of a matched raised line underneath the stationary finger on the other hand, in a yoked manner. Thus, a 6 at the moving finger would be felt as a 9 on the stationary finger. On all trials there was a raised line moving underneath the stationary fully passive finger. For the moving finger, a raised line was present on only half of the trials. When a raised line could be felt at the moving fingertip, the shape followed by this finger was more often reported than was the shape present at the other (stationary) fingertip. However, when no line was present under the moving finger (ie when movement became the major cue for shape), subjects reported experiencing the shape moved under the stationary fingertip. Results are interpreted as an indication that cutaneous information can be more ‘attention-getting’ than kinaesthetic information, and are considered to support the modality-appropriateness theory.

Clinical deterioration of ward patients in the presence of antecedents: A systematic review and narrative synthesis
Publisher: Elsevier BV
Date: 09-2018
DOI: 10.1016/J.AUCC.2018.06.004
Abstract: The aim of this review was to identify and synthesise published accounts of recognising and responding to patient deterioration in the presence of deterioration antecedents. The systematic review canvassed four electronic databases/search engines for studies of adult ward patients who had altered physiological parameters before developing major adverse events. The findings were synthesised using a narrative approach. Clinical deterioration can be missed by nurses, even with adequate charting. Delays in recognising and responding to patient deterioration remains an international patient safety concern, and strategies to enhance recognition of patient deterioration have not achieved consistent improvements. The lack of significant and sustained improvement through targeted training suggests the problem may be rooted in human behaviour and local ward culture. Nurses play a pivotal role in recognising and responding to patient deterioration however, patient records do not facilitate tracking of all nurse decisions and actions, and any undocumented care cannot be easily captured by auditing processes. Failure to recognise clinical deterioration was evident even with adequate charting. It is not clear if nurses do not recognise clinical deterioration because they failed to interpret the signs of deterioration or they made a conscious decision not to escalate based on their clinical judgement or they lacked attention at the time of the event. Whatever the reason, focus is warranted for nurses' decision-making after the recording of clinical deterioration signs and the role of human factors in delayed recognition, before maximum benefit of any strategy can be achieved.
Inattentional blindness and pattern-matching failure: The case of failure to recognize clinical cues
Publisher: Elsevier BV
Date: 11-2018
DOI: 10.1016/J.APERGO.2018.07.001
Abstract: Eye-tracking methodology was used to investigate lapses in the appropriate treatment of ward patients due to not noticing critical cues of deterioration. Forty nursing participants with different levels of experience participated in an interactive screen-based simulation of hypovolemic shock. The results show that 65% of the participants exhibited at least one episode of non-fixation on clinically relevant, fully visible cues that were in plain sight. Thirty-five percent of participants dwelt for sufficient time (>200 ms) on important cues for perception to take place, but no action followed, indicating they had pattern-matching failure. When participants fail to notice what, they should notice in patient status until it is too late, this can have serious consequences. Much work needs to be done, since these human perceptual limitations can affect patient safety in general wards.
Components of Haptic Information: Skin Rivals Kinaesthesis
Publisher: SAGE Publications
Date: 2008
DOI: 10.1068/P5855
Abstract: Four components of the haptic system were investigated, in isolation and in various combinations, during passive-guided exploration of raised-line drawings. The components were kinaesthesis, cutaneous input from the presence of a raised line, shear forces from relative movement between the skin and a textured surface, and attenuated distortions at the fingertip resulting from relative movement between the fingertip and a surface. Although the presence of kinaesthetic information was found to be positively correlated with performance in a task of identifying raised-line letters, conditions involving touch alone yielded performance equivalent to that when kinaesthesis was involved. Together, these results suggest that tactile information could be as effective as kinaesthetic information. The results are discussed in terms of applications to the design of human – machine interfaces.
