Statistical learning is lasting and consistent over time

Abstract

Implicit detection of statistical regularities is thought to be a ubiquitous facet of cognition; yet, we know little about statistical learning (SL) over time. A recent study showed that visual SL can be observed at 24 h post stimulus (Kim et al., 2009 [14]). Here we sought to obtain a finer-grained picture of visual SL over time. We employed an embedded triplet paradigm and delayed presentation of the surprise test phase, in relation to the initial familiarisation phase, across five time periods: 30 min, 1 h, 2 h, 4 h and 24 h. Results revealed a significant degree of SL at each delay period. Moreover, the degree of SL was consistent across the five delay periods. These results suggest that visual SL is remarkably consistent over time. It does not appear to be fragile and does not appear to be enhanced by sleep in healthy adults. This robustness is desirable in a mechanism thought to underpin a broad range of mental activities including language processing. Future research might use the methodology we report here to examine whether similarly stable levels of SL can be observed in individuals with language impairment, such as those with SLI and dyslexia, compared with typical peers.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
