Bullying

8.7K
A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is...

Revisionist Views of Adolescent and Adult Cognition

219
A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are...

Cognitive Development During Adolescence

397
During adolescence, individuals experience significant cognitive development that enhances their understanding of others' emotions and thoughts, known as cognitive empathy. This period is marked by an increased ability to adapt to others' perspectives and a more nuanced understanding of others' mental states, a skill that is foundational for social problem-solving and conflict avoidance. The development of cognitive empathy relies heavily on the theory of mind — the...

Cross-Sectional Research

12.2K
In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...

Longitudinal Research

13.0K
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...

Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

650
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....

Area of Science:

  • Adolescent Health
  • Digital Media Studies
  • Child Psychology

Background:

  • A significant number of Japanese adolescents use internet-connected devices.
  • The link between age of first internet use and problematic internet use (PIU) is not well understood.

Purpose of the Study:

  • To investigate the relationship between the age of initial habitual internet use and the risk of PIU in adolescents.

Main Methods:

  • A survey of 1,775 junior high school students in Japan.
  • Utilized the Young's Diagnostic Questionnaire (YDQ) to assess PIU.
  • Collected data on internet usage habits, age of first use, and smartphone ownership.

Main Results:

  • Younger age at initial weekly internet use correlated with higher PIU and longer internet use times.
  • Boys initiating internet use before age five had a 14.955 odds ratio for PIU.
  • Smartphone ownership significantly increased PIU risk in both the total population and girls.

Conclusions:

  • Early internet initiation, particularly in boys, is a strong predictor of PIU.
  • Smartphone ownership is a significant risk factor for PIU, especially in girls.
  • Longitudinal, age-appropriate internet addiction (IA) preventive education is crucial from an early age.
