Finger pointing is a natural human behavior frequently used to draw attention to specific parts of sensory input. Since this pointing behavior is likely preceded and/or accompanied by the deployment of attention by the pointing person, we hypothesize that pointing can be used as a natural means of providing self-reports of attention and, in the case of visual input, visual salience. We here introduce a new method for assessing attentional choice by asking subjects to point to and tap the first place they look at on an image appearing on an electronic tablet screen...

Christine Fawcett, Bahar Tunçgenç
Infants socially engage with others and observe others' social interactions from early in life. One characteristic found to be important for signaling and establishing affiliative social relationships is physical coordination and synchronization of movements. This study investigated whether synchrony in others' movements signals affiliation to 12- and 15-month-old infants. The infants were shown a scene in which two characters moved either synchronously or non-synchronously with a third character in the center...

Melissa Hebscher, Brian Levine, Asaf Gilboa
Spatial information is a central aspect of episodic autobiographical memory (EAM). Space-based theories of memory, including cognitive map and scene construction models, posit that spatial reinstatement is a required process during early event recall. Spatial information can be represented from both allocentric (third-person) and egocentric (first-person) perspectives during EAM, with egocentric perspectives being important for mental imagery and supported by the precuneus. Individuals differ in their tendency to rely on allocentric or egocentric information, and in general, the subjective experience of remembering in EAM differs greatly across individuals...

The recent growth in the wearable sensor market has stimulated new opportunities within the domain of Ambient Assisted Living, providing unique methods of collecting occupant information. This approach leverages contemporary wearable technology, Google Glass, to facilitate a unique first-person view of the occupants immediate environment. Machine vision techniques are employed to determine an occupant's location via environmental object detection. This method provides additional secondary benefits such as first person tracking within the environment and lack of required sensor interaction to determine occupant location...

AIM: We compared the time to initiation of cardiopulmonary resuscitation (CPR) by lay responders and/or first responders alerted either via Short Message Service (SMS) or by using a mobile application-based alert system (APP). METHODS: The Ticino Registry of Cardiac Arrest collects all data about out-of-hospital cardiac arrests (OHCAs) occurring in the Canton of Ticino. At the time of a bystander's call, the EMS dispatcher sends one ambulance and alerts the first-responders network made up of police officers or fire brigade equipped with an automatic external defibrillator, the so called "traditional" first responders, and - if the scene was considered safe - lay responders as well...

To explore the link between Sense of Embodiment (SoE) over a virtual hand and physiological regulation of skin temperature, twenty-four healthy participants were immersed in virtual reality through a Head Mounted Display and had their real limb temperature recorded by means of a high-sensitivity infrared camera. Participants observed a virtual right upper limb (appearing either normally, or with the hand detached from the forearm) or limb-shaped non-corporeal control objects (continuous or discontinuous wooden blocks) from a first-person perspective...

A new illusion is described. Randomly positioned dots moved radially within an imaginary annular window. The dots' motion periodically changed the direction, leading to an alternating percept of expanding and contracting motion. Strikingly, the apparent size of the enclosed circular region shrank during the dots' expanding phases and dilated during the contracting phases. We quantitatively measured the illusion, and found that the presence of energy at the local kinetic edge could not account for the illusion...

Feng Lu, Xiaowu Chen, Yoichi Sato
Aiming at reducing the restrictions due to person/ scene dependence, we deliver a novel method that solves appearance-based gaze estimation in a novel fashion. First, we introduce and solve an "uncalibrated gaze pattern" solely from eye images independent of the person and scene. The gaze pattern recovers gaze movements up to only scaling and translation ambiguities, via nonlinear dimension reduction and pixel motion analysis, while no training/calibration is needed. This is new in the literature and enables novel applications...

INTRODUCTION: The UK ambulance service often attends to suspected seizures. Most persons attended to will not require the facilities of a hospital emergency department (ED) and so should be managed at scene or by using alternative care pathways. Most though are transported to ED. One factor that helps explain this is paramedics can have low confidence in managing seizures. OBJECTIVES: With a view to ultimately developing additional seizure management training for practicing paramedics, we explored their learning needs, delivery preferences and potential drivers and barriers to uptake and effectiveness...

Autobiographical recollections are accompanied by visual perspectives that can be either a view through the person's own eyes (first-person) or a view that integrates visual characteristics of the rememberer into the reconstructed scene (third-person). Some have argued that a third-person perspective serves as a coping mechanism allowing the person to distance themselves from details of painful memories. The study reported here created first- and third-person memories in a novel experimental paradigm. Later, participants discriminated between these perspectives on a source memory test while event-related potentials (ERPs) were recorded...

The objective of the current paper is to report a new case of sexual murder involving human arson and summarize the literature on the phenomenon of sexual homicide. The present case study is unprecedented in Greece and a rarity in international literature due to the fact that the victim suffered genital mutilation and incineration while still alive. The evaluation consisted of 176 articles; 53 were reviewed by the authors. The results revealed sparse, but significant, research findings. The authors discuss the limitations regarding research, incidence of the phenomenon, crime-scene patterns, offender characteristics (killing methods, motive inferences, sociodemographic data, classifications, psychopathology, modus operandi), and victim selection...

Action game playing has been associated with several improvements in visual attention tasks. However, it is not clear how such changes might influence the way we overtly select information from our visual world (i.e. eye movements). We examined whether action-video-game training changed eye movement behaviour in a series of visual search tasks including conjunctive search (relatively abstracted from natural behaviour), game-related search, and more naturalistic scene search. Forty nongamers were trained in either an action first-person shooter game or a card game (control) for 10 hours...

BACKGROUND: A gap exists in understanding a provider's approach to delivering care that is mutually beneficial to patients, families, and other providers in the prehospital setting. The purpose of this study was to identify attitudes, beliefs, and perceived barriers to providing patient and family centered care (PFCC) in the prehospital setting and to describe potential solutions for improving PFCC during critical pediatric events. METHODS: We conducted a qualitative, cross-sectional study of a purposive sample of Emergency Medical Technicians (EMTs) and paramedics from an urban, municipal, fire-based EMS system, who participated in the Pediatric Simulation Training for Emergency Prehospital Providers (PediSTEPPS) course...

Hippocampal-medial prefrontal interactions are thought to play a crucial role in mental simulation. Notably, the frontal midline/medial pFC (mPFC) theta rhythm in humans has been linked to introspective thought and working memory. In parallel, theta rhythms have been proposed to coordinate processing in the medial temporal cortex, retrosplenial cortex (RSc), and parietal cortex during the movement of viewpoint in imagery, extending their association with physical movement in rodent models. Here, we used noninvasive whole-head MEG to investigate theta oscillatory power and phase-locking during the 18-sec postencoding delay period of a spatial working memory task, in which participants imagined previously learned object sequences either on a blank background (object maintenance), from a first-person viewpoint in a scene (static imagery), or moving along a path past the objects (dynamic imagery)...

PURPOSE: The role of emergency physicians in the pre-hospital management of severely injured patients remains controversial. In Germany and Austria, an emergency physician is present at the scene of an emergency situation or is called to such a scene in order to provide pre-hospital care to severely injured patients in approximately 95% of all cases. By contrast, in the United States and the United Kingdom, paramedics, i.e. non-physician teams, usually provide care to an injured person both at the scene of an incident and en route to an appropriate hospital...

Biomechanics based human identification is a major area of research. Biomechanics based approaches depend on accurately recognizing humans using body movements, the accuracy of these approaches is enhanced by incorporating the knee-hip angle to angle relationships. Current biomechanics based models are developed by considering the biomechanics of human walking and running. In biomechanics the joint angle characteristics, also known as gait features play a vital role in identification of humans. In general, identification of humans can be broadly classified into two approaches: biomechanics based approach, also known as Gait Recognition and biometric based Composite Sketch Matching...

On-scene invasive emergency procedures, such as intraosseous puncture, are often unavoidable, when indicated, and present a challenge for the emergency physician. Personal, temporal or local conditions are often unsuitable. Even with regular intervention by the emergency medical service, "last resort" measures occur very infrequently, particularly in pediatric emergencies. For the first time, this case report presents the use of intraosseous access at the humeral head with children, with reference to indication, implementation, problems and risks...

F Oldoni, V Castella, D Hall
Traces collected on crime scene objects frequently result in challenging DNA mixtures from several contributors in different DNA proportions. Understanding how the relative proportion of DNA deposited by different persons who handled the same object evolves through time has important bearings. For instance, this information may help determine whether the major contributor in a mixed DNA profile is more likely to correspond to the object owner or to the person who may have stolen this object. In this perspective, a simulation-based protocol was designed where randomly paired participants were asked to act either as first (object owner) or second (last) users...

BACKGROUND: It is important to identify the type of drugs a patient has used, especially when polydrug misuse has increased and new drugs and patterns of misuse are quickly spread. OBJECTIVES: In order to acquire sufficient information about drug use, an effective and simple form of mapping is needed. METHODS: Persons actualized for Opioid Substitution Treatment (n = 135) were interviewed about their drug-history in a two-stage model. First, they were asked to write down the drugs misused, and dot those injected with a felt pen...
