Many children diagnosed with autism spectrum disorder have difficulties identifying and labeling emotions of others. Three adolescent males all diagnosed with ASD participated in the study. In a multi-element design, the participants were trained to tact private events of others in context using novel video-based scenarios. Two of the three participants were able to increase and maintain their responding for all trained, derived, and transformation of stimulus function relations. The third participant required multiple-exemplar training of novel stimuli to increase his responding for all the video-based scenarios...

In the ongoing days, the development of sight and sound substance and information stockpiling produces colossally. Clients can extricate any kind of data they require from recordings. This outcomes in quick development of video information, client's discover complexity while procurement their important data. To address this, EBR (Event Based Ranking) propose another way to deal with group and rank mixed media occasions based recordings as per client's advantage. Clients are generally keen on the best positioned and occasion pertinent recordings of returned query output...

Behavioural observation studies in road safety research collect naturalistic data of road users that are not informed (beforehand) of their participation in a research project. It enables the observation of behavioural and situational processes that contribute to unsafe traffic events, while possible behavioural adaptations due to the road users' recognition of being observed are minimized. The literature in this field is vast and diverse, with studies dating back to the 1930s. The aim of this paper is to summarize the research efforts in the domain of road user behavioural observation research to examine trends and developments of this type of research, using a scoping review...

BACKGROUND/AIM: Peritonitis rates in peritoneal dialysis (PD) vary considerably not only across countries but also between centers in the same country. Patient education has been shown to significantly reduce infection rates but up till now training lacks standardization with patients being trained using different methods and media (e.g., illustrations, videos). As a result, patients may be insufficiently experienced in performing PD, which might be one of the causes for high peritonitis rates...

The ability to infer psychological meaning in behaviour--referred to as psychological mindedness--has been posited as a patient characteristic that contributes to the therapy process, and consequently to therapeutic success. The present study was developed to examine the relationship between patients' psychological mindedness and improvement in patients' personal treatment goals in interpretive and supportive group therapies for complicated grief, along with patients' importance to group process. The study was conducted with a clinical sample of 109 patients (79% female; average 45 years old) receiving treatment for complicated grief...

Underage patients with Borderline Personality Pathology (BPP) are in need of specialised psychotherapeutic treatment. A handful of these treatments, including Adolescent Identity Treatment (AIT) and Dialectical Behavior Therapy for Adolescents (DBT-A), have been adapted for adolescent patients. Psychotherapy research has shown that the outcome of different psychotherapeutic approaches can be very similar despite conceptual and practical differences between the theoretical models. Therefore, to understand what really works in psychotherapy, it is necessary to investigate the psychotherapeutic process and its effects on the patient...

Video-based observations of voluntary movements reveal that six species of pleuronectid flatfishes use sequential portions of long-based dorsal and anal fins as "feet" (hereafter, fin-feet) to move on the substrate. All six species used a gait that we term "walking," which produced constant forward movement, and several of these species also used a second gait that we call "bounding" for intermittent movements over the substrate. We selected Pacific Sand Sole, Psettichthys melanostictus, and English Sole, Parophrys vetulus, for kinematic analyses of these two gaits...

BACKGROUND: Web-based education is one of the leading learning pedagogies in health professions education. Students have access to a multitude of opinions, knowledge, and resources on Web, but communication among students in Web-based courses is complicated. Technology adds a filter that makes it difficult to decipher the emotions behind words or read nonverbal cues. This is a concern because students benefit more from Web-based classes when they have a high perception of social presence...

Epidemiological studies suggest tobacco consumption as a probable environmental factor for a variety of congenital anomalies, including low bone mass and increased fracture risk. Despite intensive public health initiatives to publicize the detrimental effects of tobacco use during pregnancy, approximately 10-20% of women in the United States still consume tobacco during pregnancy, some opting for so-called harm-reduction tobacco. These include Snus, a type of orally-consumed yet spit-free chewing tobacco, which is purported to expose users to fewer harmful chemicals...

Despite the availability of effective treatments for coping with traumatic experiences, a large percentage of military veterans in need do not seek help. The "I Was There" model is a new filmmaking program which is a creative-expressive tool, developed to enable veterans to reflect on their experiences and jointly create short artistic films. These artistic films articulate, often metaphorically, aspects of the veterans' service experiences, traumatic events, and reintegration challenges. The current study employed a qualitative methodology to explore participants' subjective experience of the program...

This study evaluated and compared the effectiveness of packaged video modelling (VM) and video self-modelling (VSM) interventions to develop conversational behaviors with four adolescents with autism spectrum disorder (ASD) who used augmentative and alternative communication (AAC). The study was conducted using an alternating treatments design nested within a multiple baseline design. The intervention effect was measured using Robust-Improvement Rate Difference (R-IRD). The results demonstrated that, overall, video-based modelling used in conjunction with a system of least prompts was effective in promoting conversation skills in adolescents with ASD who used AAC...

In addition to symptoms including fatigue, dizziness, reduced drive, or mood disturbance, individuals with chronic low blood pressure (hypotension) frequently report cognitive complaints. While attentional deficits have been empirically confirmed, it is still unknown whether the impairments also encompass executive functions. This study investigated cerebral blood flow modulations in hypotension during a precued antisaccade/prosaccade task requiring the executive function of proactive inhibition in addition to preparatory attention...

Imaging photoplethysmography (iPPG) is a powerful set of methods for measuring physiological signals from video. Recent advances have shown that a low-cost webcam can be used to measure heart rate, blood flow, respiration, blood oxygen levels and stress. While these methods have many beneficial applications, the unobtrusive and ubiquitous nature of the sensors risk exposing people to unwanted measurement. We present InPhysible the first camouflage system against video- based physiological measurement. The infra-red system can be embedded into any pair of glasses, or other headwear, and disrupts the measurement of the iPPG signal while being imperceptible by the human eye...

In this paper, we propose a novel heart rate (HR) estimation method using simultaneously recorded RGB and near-infrared (NIR) face videos. The key idea of our method is to automatically select suitable face patches for HR estimation in both spatial and spectral domains. The spatial and spectral face patch selection enables us to robustly estimate HR under various situations, including scenes under which existing RGB camera-based methods fail to accurately estimate HR. For a challenging scene in low light and with light fluctuations, our method can successfully estimate HR for all 20 subjects $( \pm 3$ beats per minute), while the RGB camera-based methods succeed only for 25% of the subjects...

The goal of this study is to examine the influence of various imitated and video invoked emotions on the vital signs (respiratory and pulse rates). We also perform an analysis of the possibility to extract signals from sequences acquired with cost-effective cameras. The preliminary results show that the respiratory rate allows for better separation of some emotions than the pulse rate, yet this relation highly depends on a subject. The invoked positive emotion resulted in a respiratory rate difference >1...

Estimating blood pressure (BP) from pulse arrival time (PAT) by image-based (skin video) photoplethysmography (iPPG) is of increasing interest due to the non-contact method advantage (over cuff-based methods) and potential for BP measurement to be built into portable devices such as mobile phones. The relationship between pulse transit time extracted from iPPG has been investigated during stable BP. The sensitivity of beat-to-beat iPPG-PAT to dynamic changes in BP has not been explored. This study investigated the correlation between iPPG-PAT and diastolic BP (DBP) during 1-minute seated rest and 3-minute isometric handgrip exercise...

Research in neuroscience and vision science relies heavily on careful measurements of animal subject's gaze direction. Rodents are the most widely studied animal subjects for such research because of their economic advantage and hardiness. Recently, video based eye trackers that use image processing techniques have become a popular option for gaze tracking because they are easy to use and are completely noninvasive. Although significant progress has been made in improving the accuracy and robustness of eye tracking algorithms, unfortunately, almost all of the techniques have focused on human eyes, which does not account for the unique characteristics of the rodent eye images, e...

Interest in measuring heart rates (HRs) without physical contact has increased in the area of stress checking and health care. In this paper, we propose head-motion robust video-based heart rate estimation using facial feature point fluctuations. The proposed method adaptively estimates and removes such rigid-noise components as noise stemming from horizontal head motion and extracts relatively small heart signals. Rigid-noise components can be accurately estimated and removed by using changes in facial feature points which are not dominant over heart signals and are more dominant over noise signals than are such luminance signals as RGB...
