まとめ
児童虐待は青年期の認知的柔軟性と抑制制御に悪影響を与える。しかし、ワーキングメモリは保持されているように見え、逆境体験にもかかわらず適応的なメカニズムを示唆している。
科学分野:
- 心理学
- 神経科学
- 発達心理学
背景:
- 児童虐待が実行機能に与える影響については、様々な見解が存在する。
- 認知的柔軟性、抑制制御、およびワーキングメモリに対する長期的な影響は、さらなる調査が必要である。
研究 の 目的:
- 青年期の児童虐待と実行機能に関する既存の研究を統合すること。
- 認知的柔軟性、抑制制御、およびワーキングメモリに対する具体的な影響を分析すること。
主な方法:
- 17の研究のメタアナリシスを実施した。
- 包含基準は、青年期、児童虐待の測定、および特定の実行機能評価に焦点を当てた。
- 効果量と共変量を調べるために、サブグループおよびモデレーター分析を実施した。
主要な成果:
- 児童虐待は、認知的柔軟性(g = -0.30)および抑制制御(g = -0.10)の低下と関連していた。
- ワーキングメモリは、虐待経験者と非経験者の青年期の間で有意な差はなかった(g = 0.26)。
- モデレーター分析では、ワーキングメモリが認知的柔軟性よりも肯定的な影響を受けていることが示された。
結論:
- 児童虐待は、青年期の認知的柔軟性と抑制制御を損なうが、ワーキングメモリは保持される。
- この結果は、欠損モデル(悪影響)と適応モデル(ワーキングメモリの保持)の両方を支持する。

Cognitive Development During Adulthood
737
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Cognitive Development During Adolescence

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...

Attention-Deficit/Hyperactivity Disorder

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....

Revisionist Views of Adolescent and Adult Cognition
248
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...

Information Processing Approach
469
The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is...

Socioemotional Development during Infancy
395
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.
