Neurocognitive Functioning in Adolescents at Risk for Suicidal Behaviors
Summary
Adolescents at high risk for suicide show neurocognitive impairments in complex cognition, episodic memory, and social cognition. This research aids in understanding suicide etiology and developing adolescent suicide prevention strategies.
Area of Science:
- Neuroscience
- Developmental Psychology
- Psychiatry
Background:
- Limited understanding of neurocognitive functioning in at-risk adolescents.
- Adolescence is a critical developmental period with increased suicide risk.
Purpose of the Study:
- To analyze neurocognitive performance in adolescents at high risk for suicide.
- To identify specific neurocognitive domains affected in suicidal adolescents.
Main Methods:
- 1509 adolescents sampled; 83 identified as high-risk for suicidal behaviors.
- Comparison group of 83 age- and gender-matched adolescents.
- Utilized the Paykel Suicide Scale (PSS) and the University of Pennsylvania Computerized Neurocognitive Battery for children.
Main Results:
- Significant neurocognitive impairments observed in complex cognition, episodic memory, and social cognition among high-risk adolescents.
- No significant differences in sensorimotor and executive function domains between groups.
- Findings highlight specific cognitive deficits linked to adolescent suicidality.
Conclusions:
- Neurocognitive deficits in specific domains are associated with suicide risk in adolescents.
- Contributes to understanding the etiology of suicidal thoughts and attempts.
- Provides a basis for developing targeted adolescent suicide prevention treatments.

01:18Cognitive Development During Adolescence
401
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...

01:24Revisionist Views of Adolescent and Adult Cognition
220
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...

01:17Erikson's Theory on Socioemotional Development during Adolescence
929
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...

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...

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...

01:30Negative and Cognitive Symptoms of Schizophrenia

Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...
