Color crowding considered as adaptive spatial integration.

Crowding is the inability to recognize an object in clutter, classically considered a fundamental low-level bottleneck to object recognition. Recently, however, it has been suggested that crowding, like predictive phenomena such as serial dependence, may result from optimizing strategies that exploit redundancies in natural scenes. This notion leads to several testable predictions, such as crowding being greater for nonsalient targets and, counterintuitively, that flanker interference should be associated with higher precision in judgements, leading to a lower overall error rate.

Number adaptation: Reply.

Adaptation is a ubiquitous property of perceptual systems, increasing sensitivity to change and allowing them to operate over a large dynamic range. The number sense, like most other perceptual systems, is adaptable. Yousif et al.

Revisiting Alcohol Consumption Among Nurses After the COVID-19 Pandemic: A Qualitative Descriptive Study.

The COVID-19 pandemic continues to cause nurses stress and trauma, with alcohol potentially being used to manage this stress. Prior studies of nurses' alcohol consumption during the COVID-19 pandemic have shown increases in alcohol consumption to manage stress associated with the pandemic. The aim of this paper is to explore perceptions of alcohol consumption and stress among nurses, particularly since the declared end of the COVID-19 pandemic.

Positive serial dependence in ratings of food images for appeal and calories.

Food is fundamental to survival, and our brains are highly attuned to rapidly process food stimuli. Neural signals show that foods can be discriminated as edible or inedible as early as 85 ms after stimulus onset, distinguished as processed or unprocessed beginning at 130 ms, and as high or low density from 165 ms. Recent evidence revealed specialized processing of food stimuli in the ventral visual pathway, an area that underlies perception of faces and other important objects.

Client and stakeholder perceptions of a novel, nurse practitioner-led alcohol and other drug ambulatory withdrawal service.

Introduction: Despite recommendations for ambulatory withdrawal programs appearing in many contemporary alcohol and other drug treatment guidelines, to date there have been few studies exploring such programs from client and service stakeholder perspectives. The aim of this study was to explore both individual and service stakeholder perceptions of a nurse practitioner-led ambulatory withdrawal service on the Gold Coast, Queensland, Australia.

Methods: Data were obtained from three groups: clinicians with knowledge of the service (n = 6); relatives of clients who had used the service (n = 2); and clients who had used the service (n = 10) using a Qualitative Descriptive design.

Stable Isotope Probing-nanoFTIR for Quantitation of Cellular Metabolism and Observation of Growth-Dependent Spectral Features.

This study utilizes nanoscale Fourier transform infrared spectroscopy (nanoFTIR) to perform stable isotope probing (SIP) on individual bacteria cells cultured in the presence of C-labelled glucose. SIP-nanoFTIR simultaneously quantifies single-cell metabolism through infrared spectroscopy and acquires cellular morphological information via atomic force microscopy. The redshift of the amide I peak corresponds to the isotopic enrichment of newly synthesized proteins.

Six months of voluntary alcohol consumption in male cynomolgus macaques reduces intracortical bone porosity without altering mineralization or mechanical properties.

Chronic heavy alcohol consumption is a risk factor for low trauma bone fracture. Using a non-human primate model of voluntary alcohol consumption, we investigated the effects of 6 months of ethanol intake on cortical bone in cynomolgus macaques (Macaca fascicularis). Young adult (6.

Stigma towards a nursing specialty: A qualitative analysis of the perceptions of the addiction nursing workforce.

Addiction nurses are highly skilled providers of holistic care and ensuring workforce sustainability is key to providing quality care to a traditionally marginalised group of healthcare consumers. The aim of this study was to explore perceived stigma towards the addiction nursing speciality, addiction nursing (also known as alcohol and other drug nursing) and its impact on workforce sustainability, retention and recruitment. Secondary analysis of qualitative interview data with nurses (n = 50) and survey data (n = 337) was conducted as part of a workforce mapping exercise in 2019.

Sensorimotor mechanisms selective to numerosity derived from individual differences.

We have previously shown that after few seconds of adaptation by finger-tapping, the perceived numerosity of spatial arrays and temporal sequences of visual objects displayed near the tapping region is increased or decreased, implying the existence of a (Anobile et al., 2016). To date, this mechanism has been evidenced only by adaptation.

Disambiguating vision with sound.

An important task for the visual system is to identify and segregate objects from background. Figure-ground illusions, such as Edgar Rubin's bistable 'vase-faces illusion', make the point clearly: we see either a central vase or lateral faces, alternating spontaneously, but never both images simultaneously. The border is perceptually assigned to either faces or vase, which become figure, the other shapeless background.

Adaptation to numerosity affects the pupillary light response.

We recently showed that the gain of the pupillary light response depends on numerosity, with weaker responses to fewer items. Here we show that this effect holds when the stimuli are physically identical but are perceived as less numerous due to numerosity adaptation. Twenty-eight participants adapted to low (10 dots) or high (160 dots) numerosities and subsequently watched arrays of 10-40 dots, with variable or homogeneous dot size.

Investigating cross-orientation inhibition with continuous tracking.

We investigated cross-orientation inhibition with the recently developed continuous tracking technique. We designed an experiment where participants tracked the horizontal motion of a narrow vertical grating. The target was superimposed on one of three different backgrounds, in separate sessions: a uniform gray background or a sinusoidal grating oriented either parallel or orthogonal to the target.

Serial Dependence in Perception.

Much evidence has shown that perception is biased towards previously presented similar stimuli, an effect recently termed serial dependence. Serial dependence affects nearly every aspect of perception, often causing gross perceptual distortions, especially for weak and ambiguous stimuli. Despite unwanted side-effects, empirical evidence and Bayesian modeling show that serial dependence acts to improve efficiency and is generally beneficial to the system.

The role of neural oscillations in visuo-motor communication at the time of saccades.

Saccadic eye-movements are fundamental for active vision, allowing observers to purposefully scan the environment with the high-resolution fovea. In this brief perspective we outline a series of experiments from our laboratories investigating the role of eye-movements and their consequences to active perception. We show that saccades lead to suppression of visual sensitivity at saccadic onset, and that this suppression is accompanied by endogenous neural oscillations in the delta range.

The role of non-numerical information in the perception of temporal numerosity.

Numerosity perception refers to the ability to make rapid but approximate estimates of the quantity of elements in a set (spatial numerosity) or presented sequentially (temporal numerosity). Whether numerosity is directly perceived or indirectly recomputed from non-numerical features is a highly debated issue. In the spatial domain, area and density have been suggested as the main parameters through which numerosity would be recomputed.

Serial dependence in orientation judgments at the time of saccades.

We actively seek information from the environment through saccadic eye movements, necessitating continual integration of presaccadic and postsaccadic signals, which are displaced on the retina by each saccade. We tested whether trans-saccadic integration may be related to serial dependence (a measure of how perceptual history influences current perception) by measuring how viewing a presaccadic stimulus affects the perceived orientation of a subsequent test stimulus presented around the time of a saccade. Participants reproduced the position, and orientation of a test stimulus presented around a 16° saccade.

Serial dependence improves performance and biases confidence-based decisions.

Perception depends on both the current sensory input and on the preceding stimuli history, a mechanism referred to as serial dependence (SD). One interesting, and somewhat controversial, question is whether serial dependence originates at the perceptual stage, which should lead to a sensory improvement, or at a subsequent decisional stage, causing solely a bias. Here, we studied the effects of SD in a novel manner by leveraging on the human capacity to spontaneously assess the quality of sensory information.

Future space experiment platforms for astrobiology and astrochemistry research.

Space experiments are a technically challenging but a scientifically important part of astrobiology and astrochemistry research. The International Space Station (ISS) is an excellent example of a highly successful and long-lasting research platform for experiments in space, that has provided a wealth of scientific data over the last two decades. However, future space platforms present new opportunities to conduct experiments with the potential to address key topics in astrobiology and astrochemistry.

Materials And Methods: Paired osteochondral plugs and articular chondrocytes were isolated from the relatively healthier (intact) and damaged portions of human femoral heads collected from patients undergoing total hip arthroplasty for primary osteoarthritis (OA). Cartilage from femoral plugs were either flash frozen for gene expression analysis or histology and immunohistochemistry.

Barriers and facilitators to becoming an alcohol and other drug nurse practitioner in Australia: A mixed methods study.

Alcohol and other drug (AOD) nurse practitioners have an advanced scope of practice that allows them to diagnose, prescribe pharmacological treatments for alcohol and other substance use disorders, and monitor physical and mental health. The Behaviour Change Wheel (BCW) is used to understand barriers and facilitators to implementation by applying three conditions of behaviour change (capability, opportunity, and motivation-the COM-B framework). The aim of this paper is to describe the current AOD nurse practitioner workforce, and to explore barriers and facilitators to AOD nurse practitioner uptake in Australia.
