#1
Aytaç Karabay, Elkan G Akyürek
Performance in rapid serial visual presentation tasks has been shown to depend on the temporal integration of target stimuli when they are presented in direct succession. Temporal target integration produces a single, combined representation of visually compatible stimuli, which is comparatively easy to identify. It is currently unknown to what extent target compatibility affects this perceptual behavior, because it has not been studied systematically to date. In the present study, the effects of compatibility on temporal integration and attention were investigated by manipulating the Gestalt properties of target features...

BACKGROUND: Since psychological tests such as questionnaire or drawing tests are almost qualitative, their results carry a degree of uncertainty and sometimes subjectivity. The deficiency of all drawing tests is that the assessment is carried out after drawing the objects and lots of information such as pen angle, speed, curvature and pressure are missed through the test. In other words, the psychologists cannot assess their patients while running the tests. One of the famous drawing tests to measure the degree of Obsession Compulsion Disorder (OCD) is the Bender Gestalt, though its reliability is not promising...

INTRODUCTION: Sotos syndrome is a congenital overgrowth disorder characterized by facial gestalt, excessively rapid growth, acromegalic features and a non-progressive cerebral disorder with intellectual disability. METHODOLOGY: The identical male twins showed somewhat different clinical, cognitive and behavioural phenotypes. Abnormal clinical manifestations including seizures, scoliosis, enlarged ventricles, and attention-deficit/hyperactivity disorder (ADHD) were found in the proband (first twin), but not in the sibling (second twin)...

BACKGROUND: ACS-TQIP Best Practices recommends initial massive transfusion (MT) cooler delivery within 15 minutes of protocol activation, with a goal of 10 minutes. The current study sought to examine the impact of timing of first cooler delivery on patient outcomes. METHODS: Patients predicted to receive MT at 12 level-1 trauma centers were randomized to two separate transfusion ratios as described in the PROPPR trial. ABC score or clinician gestalt prediction of MT was used to randomize patients and call for initial study cooler...

The temporal relationship between individual pieces of information from the different sensory modalities is one of the stronger cues to integrate such information into a unified perceptual gestalt, conveying numerous perceptual and behavioral advantages. Temporal acuity, however, varies greatly over the life span. It has previously been hypothesized that changes in temporal acuity in both development and healthy aging may thus play a key role in integrative abilities. This study tested the temporal acuity of 138 individuals ranging in age from 5 to 80...

Alexander Pastukhov
Our visual system combines sensory evidence with prior knowledge to produce a representation of an outside world. Here, we explored the limits of the feedforward computation using an ambiguously rotating human biological motion. Specifically, we investigated whether an overall rotation, which was added to all the displays used in the study, would be perceived when the point-light walker was presented upside-down, a condition that typically obliterates perception of a human Gestalt. We report that inversion of the point-light walker or the absence of an identifiable Gestalt abolished the perception of an overall rotation...

This study examined the impact of gestalt intervention groups for anxious Chinese parents in Hong Kong. A non-randomized control group pre-test/post-test design was adopted. A total of 156 parents participated in the project. After 4 weeks of treatment, the intervention group participants had lower anxiety levels, less avoidance of inner experiences, and more kindness towards oneself and mindfulness when compared to control group participants. However, the dimension of self-judgment remained unchanged. The adaptation of gestalt intervention to suit the Chinese culture was discussed...

Native American myopathy (NAM) is an autosomal recessive congenital myopathy, up till now exclusively described in Lumbee Indians who harbor one single homozygous mutation (c.1046G>C, pW284S) in the STAC3 gene, encoding a protein important for proper excitation-contraction coupling in muscle. Here, we report the first non-Amerindian patient of Turkish ancestry, being compound heterozygous for the mutations c.862A>T (p.K288*) and c.432+4A>T (aberrant splicing with skipping of exon 4). Symptoms in NAM include congenital muscle weakness and contractures, progressive scoliosis, early ventilatory failure, a peculiar facial gestalt with mild ptosis and downturned corners of the mouth, short stature, and marked susceptibility to malignant hyperthermia...

AIM: To test accuracy and reproducibility of gestalt to predict obstructive coronary artery disease (CAD) in patients with acute chest pain. METHODS: We studied individuals who were consecutively admitted to our Chest Pain Unit. At admission, investigators performed a standardized interview and recorded 14 chest pain features. Based on these features, a cardiologist who was blind to other clinical characteristics made unstructured judgment of CAD probability, both numerically and categorically...

Simultanagnosia is a neuropsychological deficit of higher visual processes caused by temporo-parietal brain damage. It is characterized by a specific failure of recognition of a global visual Gestalt, like a visual scene or complex objects, consisting of local elements. In this study we investigated to what extend this deficit should be understood as a deficit related to specifically the visual domain or whether it should be seen as defective Gestalt processing per se. To examine if simultanagnosia occurs across sensory domains, we designed several auditory experiments sharing typical characteristics of visual tasks that are known to be particularly demanding for patients suffering from simultanagnosia...

Peter A White
Many studies of perceptual impressions of causality have used a stimulus in which a moving object (the launcher) contacts a stationary object (the target) and the latter then moves off. Such stimuli give rise to an impression that the launcher makes the target move. In the present experiments, instead of a single target object, an array of four vertically aligned objects was used. The launcher contacted none of them, but stopped at a point between the two central objects. The four objects then moved with similar motion properties, exhibiting the Gestalt property of common fate...

Anthony D Kauders
The article intends to retrace and review German discourse on hypnotic suggestion from 1900 onward, demonstrating the variety of arguments advanced to account for the social relationship in the hypnotic setting well before the emergence of sociocognitive theory. Using Spanos's distinction between "happenings" and "doings," it shows how, in the case of the "social" in early 20th century German texts on (hypnotic) suggestion, the passive observer, recipient, or victim of hypnosis, a trope familiar to the discipline for many decades, was called into question...

In usage-based linguistic theories, the assumption that high-frequency language strings are mentally represented as unitary chunks has been invoked to account for a wide range of phenomena. However, neurocognitive evidence in support of this assumption is still lacking. In line with Gestalt psychological assumptions, we propose that a language string qualifies as a chunk if the following two conditions are simultaneously satisfied: The perception of the whole string does not involve strong activation of its individual component parts, but the component parts in isolation strongly evoke the whole...

In 1923, Gelb and Granit, using a method of adjustment for a small red light, reported a lower threshold for the target when presented on a ground region than on an adjacent figural region. More recent work in perceptual organization has found precisely the opposite-a processing advantage seems to go to items presented on the figure, not the ground. Although Gelb and Granit continue to be cited for their finding, it has not previously been available as an English translation. Understanding their methodology and results is important for integrating early Gestalt theory with more recent investigations...

Frances M Russell, Robert R Ehrman
BACKGROUND: Multiorgan ultrasound (US), which includes evaluation of the lungs and heart, is an accurate method that outperforms clinical gestalt for diagnosing acutely decompensated heart failure (ADHF). A known barrier to ultrasound use is the time needed to perform these examinations. OBJECTIVE: The primary goal of this study was to determine the test characteristics of a modified lung and cardiac US (LuCUS) protocol for the accurate diagnosis of ADHF. METHODS: This was a secondary analysis of a prospective observational study that enrolled adult patients presenting to the emergency department with undifferentiated dyspnea...

Objective: Perception of time as well as rhythm in musical structures rely on complex brain mechanisms and require an extended network of multiple neural sources. They are therefore sensitive to impairment. Several psychophysical studies have shown that patients with Parkinson's disease (PD) have deficits in perceiving time and rhythms due to a malfunction of the basal ganglia (BG) network. Method: In this study we investigated the time perception of PD patients during music perception by assessing their just noticeable difference (JND) in the time perception of a complex musical Gestalt...

STUDY OBJECTIVE: Open educational resources such as blogs are increasingly used for medical education. Gestalt is generally the evaluation method used for these resources; however, little information has been published on it. We aim to evaluate the reliability of gestalt in the assessment of emergency medicine blogs. METHODS: We identified 60 English-language emergency medicine Web sites that posted clinically oriented blogs between January 1, 2016, and February 24, 2016...

This study evaluates foster care history characteristics as risk factors for psychopathology. We examine characteristics of youths' foster care histories separately and as a gestalt (i.e., identification of latent classes). Six mental health disorders and lifetime suicide attempt were assessed via in-person interviews with a representative sample of older adolescents in California foster care (n = 706). Information on respondents' foster care histories were obtained from state administrative data. Half of the sample (47...

PURPOSE: Online open educational resources are increasingly used in medical education, particularly blogs and podcasts. However, it is unclear whether these resources can be adequately appraised by end-users. Our goal was to determine whether gestalt-based recommendations are sufficient for emergency medicine trainees and attending physicians to reliably recommend online educational resources to others. METHODS: Raters (33 trainees and 21 attendings in emergency medicine from North America) were asked to rate 40 blog posts according to whether, based on their gestalt, they would recommend the resource to (1) a trainee or (2) an attending physician...
