Longitudinal Studies01:26

Longitudinal Studies

483
Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Longitudinal Research

13.1K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Socioemotional Development during Infancy

435
Socio-emotional development in infancy is primarily shaped by early emotional responses and social connections, with temperament playing a central role. Temperament refers to the consistent patterns in an individual's emotional and behavioral responses, observable even in infancy. By examining temperament, researchers can better understand an infant's unique ways of interacting with the world, influencing subsequent personality and socio-emotional growth.

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

414
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Excitatory and Inhibitory Effects of Neurotransmitters01:29

Excitatory and Inhibitory Effects of Neurotransmitters

12.7K
When an action potential reaches the presynaptic axon terminal, it releases neurotransmitters from the neuron into the synaptic cleft at a chemical synapse. The released neurotransmitter can be excitatory or inhibitory. The critical criteria commonly used to determine whether a molecule is a neurotransmitter at a chemical synapse are the molecule's presence in the presynaptic neuron. Second, its release is in response to strong presynaptic depolarization. And lastly, the presence of...

Microbial Growth Media01:27

Microbial Growth Media

1.4K
Microbial growth media are essential tools in microbiology, providing the nutrients and conditions necessary to cultivate and study microorganisms. These media are categorized by their composition, consistency, and functional roles, enabling researchers to investigate microbial physiology, behavior, and interactions.Types and Consistencies of Growth MediaGrowth media can be solid, liquid, or semisolid. Solid media, often agar-based, allow visible colony growth for isolation and enumeration.

Summary
This summary is machine-generated.

Excessive screen time in toddlers, particularly background television, is linked to poorer inhibitory control skills. This executive function development may be sensitive to screen exposure during early childhood.

Area of Science:

  • Developmental Psychology
  • Cognitive Neuroscience
  • Media Studies

Background:

  • Inhibitory control is a key executive function for behavioral regulation.
  • Screen media exposure may negatively impact executive functions in early childhood.
  • Toddlerhood is a sensitive period for development due to reliance on social learning.

Purpose of the Study:

  • To examine the association between toddlers' inhibitory control and screen media exposure.
  • To investigate the impact of screen time duration and context (background TV, parental media use for emotion regulation) on inhibitory control.
  • To explore these associations during a sensitive developmental period.

Main Methods:

  • Longitudinal study with 75 infants and mothers, assessed at 11.8 months and 31.1 months.
  • Mothers reported on screen time and background television.
  • Children completed inhibitory control tasks; parents provided ratings.

Main Results:

  • Greater background television exposure was linked to poorer performance on inhibitory control tasks.
  • Higher overall screen time predicted shorter delay of gratification.
  • Parental ratings of inhibitory control were not associated with screen media use.

Conclusions:

  • Toddlers' inhibitory control may be negatively associated with background television and overall screen time duration.
  • Early childhood screen exposure warrants attention regarding its impact on executive function development.
  • Findings highlight potential risks of screen media during sensitive developmental periods.
