AI Article Synopsis
- The study investigates whether Developmental Prosopagnosics (DPs) have deficits in holistic face processing, which is commonly assumed to be crucial for face recognition.
- Mixed findings from previous research suggest that the diversity of DPs' deficits and the different ways holistic processing is measured contribute to the confusion.
- The current research found that while DPs have reduced but not absent holistic processing effects in certain tests, individual cases reveal varied levels of these deficits, indicating a complex relationship between holistic processing and face recognition in DPs.
Article Abstract
Although it is generally assumed that face recognition relies on holistic processing, whether face recognition deficits observed in Developmental Prosopagnosics (DPs) can be explained by impaired holistic processing is currently under debate. The mixed findings from past studies could be the consequence of DP's heterogeneous deficit nature and the use of different measures of holistic processing-the inversion, part-whole, and composite tasks-which showed a poor association among each other. The present study aimed to gain further insight into the role of holistic processing in DPs. Groups of DPs and neurotypicals completed three tests measuring holistic face processing and non-face objects (i.e., Navon task). At a group level, DPs showed (1) diminished, but not absent, inversion and part-whole effects, (2) comparable magnitudes of the composite face effect and (3) global precedence effect in the Navon task. However, single-case analyses showed that these holistic processing deficits in DPs are .

Contrastive learning with transformer for adverse endpoint prediction in patients on DAPT post-coronary stent implantation.

Background: Effective management of dual antiplatelet therapy (DAPT) following drug-eluting stent (DES) implantation is crucial for preventing adverse events. Traditional prognostic tools, such as rule-based methods or Cox regression, despite their widespread use and ease, tend to yield moderate predictive accuracy within predetermined timeframes. This study introduces a new contrastive learning-based approach to enhance prediction efficacy over multiple time intervals.

Background: Municipality-based pediatric palliative care (PPC) is recommended to promote the quality of life for the child and family by enabling them to stay at home as much as possible. However, municipality-based PPC presents complex challenges and places significant demands on healthcare professionals. Yet, it remains an underexplored field.

Department of Psychology, Stellenbosch University, Stellenbosch, South Africa.
Objectives: Palliative care, which was formally established in the Global North, is now recognized globally as part of health care. As part of a larger study, we were interested in how decision-makers at a leading hospice in South Africa understood the changing local context and its influence on the delivery of services. We were interested in how the concept of "total pain," as outlined by Saunders, applies in a very unequal and under-resourced society in the shadow of a long, oppressive colonial, and apartheid past.

Background: Several studies have found that immigrants and descendants are less physically active than the majority population, particularly within sports clubs. However, most studies do not provide breakdowns by specific ethnic groups or organisational forms. Therefore, our paper analyses the influence of ethnicity, immigrant status, and sociodemographic and -economic characteristics on the physical activity participation of immigrants and descendants in sports clubs, commercial centres and self-organised activities in Denmark.
