背景情况:
- 强迫性行为是神经精神障碍的跨诊断特征,如强迫症,自闭症和精神分裂症.
- 研究领域标准 (RDoC) 策略有助于理解强迫性的神经心理基础.
- 高饮酒者 (HD) 与低饮酒者 (LD) 的动物模型,通过时间表诱导的多症 (SIP) 进行选择,作为强迫性的临床前模型.
研究的目的:
- 调查强迫性HD老鼠表型中的认知控制和负价值系统领域.
- 评估HD大鼠的行为不灵活性,冲动性和风险决策.
主要方法:
- 选择HD和LD大鼠使用时间表诱导的多症 (SIP).
- 使用概率空间逆转学习 (PSRL) 评估行为不灵活性.

01:28Obsessive-Compulsive Disorder
168
Obsessive-compulsive disorder (OCD) is a mental health condition characterized by recurrent obsessions, compulsions, or both, which consume significant time and interfere with daily functioning. Obsessions involve persistent, intrusive, and unwanted thoughts, images, or urges that evoke anxiety. Common examples include irrational fears of contamination or harm. Compulsions are repetitive behaviors or mental acts performed to reduce the anxiety caused by obsessions. For instance, individuals...

Central to this approach is the notion that behaviors, both adaptive and maladaptive, are learned through reinforcement. By analyzing the environmental factors that reinforce problematic behaviors, clinicians can design interventions to weaken these reinforcements and replace maladaptive behaviors with healthier alternatives.
