Inhibition in large set sizes depends on search mode, not salience.

Attention can be attracted to salient items in a visual scene. Recent studies have shown that when the feature of an irrelevant salient item is known, it can be suppressed below baseline leading to facilitated search. Wang and Theeuwes (Experimental Psychology: Human Perception and Performance, 46(10), 1051-1057, 2020) criticised previous inhibition studies by claiming that the sparse displays attenuated the salience of the distractors.

Disentangling the contributions of spatiotopic, retinotopic, and configural frames of reference to the filtering of probable distractor locations.

Human observers can allocate their attention to locations likely to contain a target and can also learn to avoid locations likely to contain a salient distractor during visual search. However, it is unclear which spatial frame of reference such learning is applied to. As such, our aim was to systematically disentangle the contributions of spatiotopic, retinotopic, and configural frames of reference to provide a comprehensive account of how the probabilistic distractor filtering effect comes about.

Plasma brain-derived neurotrophic factor concentrations are elevated in community-dwelling adults with sarcopenia.

Background: The scalability of a blood-based sarcopenia assessment has generated interest in circulating markers that may enhance management strategies. Data regarding the relevance of brain derived neurotrophic factor (BDNF), a regulator of neuroplasticity, to sarcopenia in community-dwelling adults are scarce. We examined the association between plasma BDNF concentrations, sarcopenia and individual sarcopenia signatures in a well-characterised adult cohort.

Maximising translational value of the Iowa gambling task in preclinical studies through the use of the rodent touchscreen.

The Iowa gambling task is widely employed to assess the evaluation of risk versus reward contingencies, and how the evaluations are implemented to gain advantageous returns. The cognitive processes involved can be compromised in psychiatric conditions, leading to the development of analogous tasks with translational value for use in rodents. The rodent touchscreen apparatus maximises the degree of similarity with the human task, and in this review we provide an outline of the use of rodent touchscreen gambling tasks in preclinical studies of psychiatric conditions.

Dual-energy x-ray absorptiometry derived body composition trajectories across adulthood: Reference values and associations with body roundness index and body mass index.

Background: Population-specific reference values are needed to accurately contextualise age-related changes in body composition. This study aimed to a) establish age- and sex-specific reference values and cut-points for a range of dual-energy x-ray absorptiometry (DXA) derived metrics of lean mass (LM), fat mass (FM) and bone mineral density (BMD), across adulthood in a large adult cohort; and b) determine the association between DXA-derived body composition, body roundness index (BRI), and body mass index (BMI).

Methods: Cross-sectional data were collected from 10,033 men and women aged from 18 to 92 years.
