Revisionist Views of Adolescent and Adult Cognition01:24

Revisionist Views of Adolescent and Adult Cognition

438
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...

Self-Report Tests of Personality01:22

Self-Report Tests of Personality

1.2K
Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

The development of cognitive empathy relies heavily on the theory of mind — the...

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Erikson's Theory on Socioemotional Development during Adolescence

2.0K
Erik Erikson's fifth stage of psychosocial development, "identity versus role confusion," is crucial during adolescence (ages 12 to 18). In this stage, adolescents face the developmental task of forging a distinct personal identity, a process influenced by social, psychological, and biological changes typical of this period. Adolescents naturally explore different roles, behaviors, and ideologies as they navigate complex questions of self-concept, asking, "Who am I?" and "What is my place in...

Area of Science:

  • Psychology
  • Adolescent Health
  • Digital Media Studies

Background:

  • Adolescent Internet use raises significant psychological and behavioral concerns.
  • Early detection of problematic Internet use is crucial for timely intervention.
  • Validated screening tools are needed to identify at-risk youth.

Purpose of the Study:

  • To develop and validate a brief, culturally adapted tool for screening problematic Internet use in adolescents.
  • To provide a reliable instrument for early detection and risk assessment.

Main Methods:

  • Development of an 11-item scale based on expert input and existing literature.
  • Psychometric evaluation using a sample of 1,709 Spanish secondary school students (ages 11-17).
  • Confirmatory Factorial Analysis to assess internal structure, reliability, sensitivity, and specificity.

Main Results:

  • The 11-item scale demonstrated satisfactory reliability (α = .82).
  • Internal structure was confirmed via Confirmatory Factorial Analysis.
  • The tool achieved high sensitivity (81%) and specificity (82.6%) for detecting problematic Internet use.

Conclusions:

  • The developed scale is a brief, reliable, and valid instrument for screening problematic Internet use in adolescents.
  • It facilitates the gradation of risk along a continuum, offering significant applied potential in educational and clinical settings.
  • The tool is culturally adapted to the Spanish context and youth language.
