Children

Area of Science:

  • Developmental Psychology
  • Motor Control
  • Human Movement Science

Background:

  • Hand preference emerges early but refines through childhood.
  • Understanding developmental changes in hand selection is crucial for motor control research.

Purpose of the Study:

  • To investigate hand selection in preadolescent children (9-11 years) during a preferential reaching task.
  • To compare children's hand selection strategies with those of young adults.
  • To determine the influence of object location, orientation, and task intention on hand selection.

Main Methods:

  • A preferential reaching task was employed to assess hand selection in preadolescent children.
  • Object location, orientation, and task intention were systematically varied.
  • Data were compared with previously collected data from young adults.

Main Results:

  • Children's movement patterns indicate ongoing refinement towards efficient behavior.
  • Similarities in hand selection were observed between preadolescents and young adults.
  • Object proximity and orientation significantly influenced hand selection, favoring the right hand in right-sided space and with right-oriented handles.

Conclusions:

  • Findings highlight developmental differences and similarities in hand selection between children and adults.
  • Object properties and spatial context constrain hand selection in both unimanual and bimanual manipulation tasks.
  • This study contributes to the understanding of hand preference development and object manipulation.

Location and Orientation of the Heart01:13

Location and Orientation of the Heart

The human heart, despite its modest size and weight, is an organ of remarkable strength and endurance. Roughly the size of a fist, the heart weighs between 250 and 350 grams and is nestled within the mediastinum, the medial cavity of the thorax. It extends obliquely for about 12 to 14 cm, resting on the superior surface of the diaphragm. The heart is positioned anterior to the vertebral column and posterior to the sternum, with two-thirds of its mass lying to the left of the midsternal line.

Selected Data About Geographic Locations

Geographic Information Systems (GIS) rely on two core types of data: spatial data and attribute data.Spatial DataSpatial data defines the physical location of features within a coordinate system, typically expressed in terms of latitude and longitude. It provides precise positioning for elements like roads, rivers, or buildings.Attribute DataAttribute data complements spatial data by adding descriptive information about these features. For example, a road's spatial data includes its start and...

Hand hygiene01:23

Hand hygiene

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Velocity of an Object01:18

Velocity of an Object

Understanding how an object moves along a path requires distinguishing between motion over a time span and motion at a precise moment. A useful example is a vehicle traveling along a straight and level path, where its position at any given time is known. The initial step in analyzing this motion is to measure how far the vehicle travels over a fixed time period. This measurement, called average velocity, is computed by dividing the total change in position by the duration over which the change...

Frequency-dependent Selection01:21

Frequency-dependent Selection

When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

Perceiving Loudness, Pitch, and Location01:21

Perceiving Loudness, Pitch, and Location

The human brain perceives pitch through two primary mechanisms reflected in place theory and frequency theory. Each mechanism describes how sound waves are interpreted as specific pitches by the brain, offering insights into the intricate processes of auditory perception.
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...
