概括
认知发展因物种而异. 与人类不同,古皮犬表现出早期的抑制控制,而斑马鱼则在晚些时候发展出来,突出显示了发育模式对认知进展的影响.
科学领域:
- 比较认知能力的比较
- 发育生物学 发展生物学
- 神经科学是一个神经科学.
背景情况:
- 传统研究表明,认知能力是在出生后发展的,特别是在像人类这样的其他社会物种中.
- 这种发展轨迹可能不适用于所有动物物种.
研究的目的:
- 调查不同发育模式是否影响认知发展模式.
- 测试这样的假设:具有不同发育策略的物种表现出明显的认知进展.
主要方法:
- 在斑马鱼 (Danio rerio) 和鱼 (Poecilia reticulata) 中使用自发行为范式评估抑制控制.
- 评估了两种物种不同年龄段的认知表现,以解释发育变异.
主要成果:
- 斑马鱼表现出极端的其他性,在幼虫早期阶段没有表现出抑制控制,在一个月后发展出来.
- 古皮犬出生时高度发达,从生命早期就表现出抑制性控制,随着性成熟,表现得到改善.
结论:
- 一种物种的发育模式对认知发育模式产生重大影响.
- 认知本体发生不是统一的,并且可以根据物种的生命历史战略而有所不同.

01:28Psychometric Approach of Cognitive Development
The psychometric approach examines cognitive development by measuring individual differences in abilities that contribute to intelligence. Intelligence includes the capacity to learn, remember, apply knowledge, understand relationships among concepts, and solve everyday problems. Intelligent behavior is generally goal-directed and adaptive because it helps individuals achieve objectives and adjust to changing situations.Intelligence Testing in ChildrenIn school-age children, intelligence is...
01:21Cognitive Neuroscience Approach
The cognitive neuroscience approach to development focuses on how the central nervous system supports emerging cognitive abilities. Neuroimaging and behavioral studies link specific neural systems to memory and cognitive processing in infancy.Distinct Memory Systems in the Developing BrainInfant long-term memory includes two distinct systems: implicit and explicit memory. Implicit, or nondeclarative, memory involves unconscious recall of skills and routines. It develops early and appears in...
