Cognitive conflict could facilitate negative stimulus processing: evidence from trait anxiety in the flanker paradigm

Neuroreport

Abstract

The present study used event-related potentials to investigate the affective priming effect of cognitive conflict and the influence of trait anxiety during the early stage of conflict processing. Participants with relatively high-trait or low-trait anxiety were tested using a combination of flanker task (congruent or incongruent arrows) as primes presented 200 ms before positive or negative words as targets. Behavioral results showed that response times were shorter for negative targets following incongruent primes relative to congruent primes, and vice versa, suggesting that conflicts facilitated the processing of negative targets. Event-related potential results revealed that the N2 amplitudes (280-320 ms) for incongruent stimuli were significantly more negative than those for congruent stimuli, indicating a significant conflict effect. Moreover, the N400 amplitudes (580-680 ms) for positive targets after congruent primes were significantly more negative than those after incongruent primes, but no significant difference was found in the N400 amplitudes after congruent primes and incongruent primes for negative targets, indicating that conflicts had a negative effect on the subsequent processing. In addition, in the high-trait...Continue Reading

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.
