Within-item strategy switching: an age comparative study in adults

Psychology and Aging
Eléonore Ardiale, Patrick Lemaire

Abstract

Two experiments tested whether participants switched strategies while they are solving problems and age-related changes in such within-item strategy switching. Young and older adults performed a computational estimation task. Participants had to provide estimates of two-digit multiplication problems like 58 × 72, with either a rounding-down strategy (i.e., doing 50 × 70 = 3,500 to find a product estimate for 58 × 72) or a rounding-up strategy (i.e., doing 60 × 80 = 4,800). In Experiment 1, participants had the possibility to switch strategies after executing a current strategy for 1,000 ms if they judged the current strategy not the best strategy. In Experiment 2, participants were told to switch to another strategy 1,000 ms after starting to execute one strategy in strategy switch items, or to continue to execute the same strategy on strategy noswitch items. The main findings showed that (a) participants were able to switch strategies within items, especially when they started to execute the poorer strategy and when it was easier to determine which strategy is the best on a given problem, (b) older adults switched less often than young adults, especially in conditions where young adults switched most often, (c) switching helpe...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.
