Schemas

Schemas

A schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

Insufficient Sleep and Sleep Deprivation

Insufficient Sleep and Sleep Deprivation

Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.
Sleep deprivation is a more severe form of sleep loss...

Piaget's Stage 1 of Cognitive Development

Piaget's Stage 1 of Cognitive Development

The sensorimotor stage, the initial phase of Jean Piaget's theory of cognitive development, spans the first two years of a child's life. During this period, infants actively engage with their surroundings, building cognitive awareness through direct interaction with the world. This interaction is primarily based on sensory perception and motor actions, allowing infants to gradually understand basic physical properties and predict how objects interact within their environment.

Attention-Deficit/Hyperactivity Disorder

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Summary

Infants understand that cellphone use can impair adult performance. Even at 20 months old, babies expect phone use to negatively impact task completion, recognizing multitasking effects.

Area of Science:

Cognitive Development
Infant Psychology
Human-Computer Interaction

Background:

Adults frequently use cellphones in the presence of infants.
Limited research exists on infants' understanding of others' cellphone usage and its impact on behavior.

Purpose of the Study:

To investigate whether 20-month-old infants anticipate that cellphone use negatively affects an adult's task performance.
To explore infants' early recognition of multitasking's influence on goal-directed actions.

Main Methods:

Infants observed adults building block towers.
One adult engaged with a cellphone (scrolling or talking) while performing the task.
Infants' looking times were measured to infer expectations about performance differences.

Main Results:

Infants looked longer when the phone-using adult built a taller tower than the non-using adult, relative to the reverse scenario.
This differential looking suggests an expectation that phone use would hinder performance.

Conclusions:

Twenty-month-old infants demonstrate an understanding that cellphone use can impair an individual's performance.
This finding indicates an early developmental awareness of how multitasking affects goal-directed actions.
