The role of the human hippocampus in decision-making under uncertainty
The role of the hippocampus in decision-making is beginning to be more understood. Because of its prospective and inferential functions, we hypothesized that it might be required specifically when decisions involve the evaluation of uncertain values. A group of individuals with autoimmune limbic encephalitis-a condition known to focally affect the hippocampus-were tested on how they evaluate reward against uncertainty compared to reward against a…
Human ventromedial prefrontal cortex is necessary for prosocial motivation
Ventromedial prefrontal cortex (vmPFC) is vital for decision-making. Functional neuroimaging links vmPFC to processing rewards and effort, while parallel work suggests vmPFC involvement in prosocial behaviour. However, the necessity of vmPFC for these functions is unknown. Patients with rare focal vmPFC lesions (n = 25), patients with lesions elsewhere (n = 15) and healthy controls (n = 40) chose between rest and exerting effort to earn rewards f…
Month neurological and psychiatric outcomes in 236 379 survivors of Covid-19: A retrospective cohort study using electronic health records
BACKGROUND: Neurological and psychiatric sequelae of COVID-19 have been reported, but more data are needed to adequately assess the effects of COVID-19 on brain health. We aimed to provide robust estimates of incidence rates and relative risks of neurological and psychiatric diagnoses in patients in the 6 months following a COVID-19 diagnosis. METHODS: For this retrospective cohort study and time-to-event analysis, we used data obtained from the …
Impact of processing demands at encoding, maintenance and retrieval in visual working memory
There has been surprisingly little examination of how recall performance is affected by processing demands induced by retrieval cues, how manipulations at encoding interact with processing demands during maintenance or due to the retrieval cue, and how these are affected with aging. Here, we investigate these relationships by examining the fidelity of working memory recall across two delayed reproduction tasks with a continuous measure of report …
The computational cost of active information sampling before decision-making under uncertainty
Recall cues interfere with retrieval from visuospatial working memory
Visuospatial working memory allows us to hold multiple visual objects over short delays. It is typically tested by presenting an array of objects, then after a delay showing a 'probe' indicating which memory item to recall or reproduce by adjusting a target feature. However, recent studies demonstrate that information at the time of probe can disrupt recall. Here, in three experiments we test whether traditional memory probes, which contain featu…
Can technology change the existing culture? Case study on Bangladesh's public sector
This article highlights the challenges development aid donors can face in Bangladesh’s post-colonial culture, as well as substantiating how lack of quality control in an aid project can influence local values, beliefs, and subjective experiences. The article also suggests that improving quality control, such as through monitoring and evaluation (M&E), can generate greater impact of development aid resources
Prosocial apathy for helping others when effort is required
Indigenous Autonomy, Community-Based Research, and Development aid: Sumaq kawsay in three epistemic scenarios
In this paper, the future of Indigenous autonomy and Indigenous community-based research is illustrated by analyzing re-Westernization, de-Westernization, and decoloniality in relation to the regeneration of the Indigenous glocal (global/local) concept of sumaq kawsay (“living well” in Quechua). The regeneration of sumaq kawsay as a new geopolitical and cultural polycentric and multipolar world is examined from an Indigenous studies decolonial pe…
Changing concepts of working memory
The precision of visual working memory is set by allocation of a shared resource
The mechanisms underlying visual working memory have recently become controversial. One account proposes a small number of memory "slots," each capable of storing a single visual object with fixed precision. A contrary view holds that working memory is a shared resource, with no upper limit on the number of items stored; instead, the more items that are held in memory, the less precisely each can be recalled. Recent findings from a color report t…
Dynamic Shifts of Limited Working Memory Resources in Human Vision
Our ability to remember what we have seen is very limited. Most current views characterize this limit as a fixed number of items—only four objects—that can be held in visual working memory. We show that visual memory capacity is not fixed by the number of objects, but rather is a limited resource that is shared out dynamically between all items in the visual scene. This resource can be shifted flexibly between objects, with allocation biased by s…
