Early understanding of mental entities: a reexamination of childhood realism

Child Development
H M Wellman, D Estes

Abstract

Real physical objects (e.g., a chair) can be distinguished from mental entities (e.g., a thought about a chair) on the basis of a number of criteria. 3 of these are behavioral-sensory evidence--whether the entity can be seen, touched, and physically acted upon; public existence--whether other persons experience the entity; and consistent existence--whether the entity consistently exists over time. Two studies tested 3-5-year-old children's ability to distinguish real versus mental entities on the basis of these criteria and to categorize such entities suitably. Even 3-year-olds were able to judge real and mental entities appropriately on the basis of the 3 criteria, to sort such entities as explicitly real and not-real, and to provide cogent explanations of their choices as well. A further distinction between real and mental entities is that mental entities can be about physically impossible, nonexistent things (e.g., a dog that flies). A third study demonstrated that 3-5-year-olds also appreciated this distinction. Taken together, these results contradict a common characterization of the young child as unaware of the fundamental ontological distinction between the internal mental world and objective reality. The implications o...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.
