Implicit Memories01:24

Implicit Memories

100
Implicit memories, also known as non-declarative memories, are long-term memories that function outside of conscious awareness. These memories influence behavior and skills without explicit knowledge. This type of memory is evident in tasks like playing tennis, snowboarding, and texting. Implicit memory has three subsystems: procedural memory, conditioning, and priming. This type of memory is essential in various activities, from everyday tasks to specialized skills.
One key aspect of implicit...

Cognitive Development During Adulthood01:30

Cognitive Development During Adulthood

61
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,...

Interference and Decay01:16

Interference and Decay

114
Forgetting is a complex cognitive phenomenon influenced by several factors, among which interference and decay are particularly prominent. These processes explain why individuals often struggle to retrieve specific information from memory, leading to lapses in recall that can be observed in everyday situations.
Interference occurs when competing memories hinder the retrieval of particular information. It can be classified into two types: proactive and retroactive interference. Proactive...

Stereotypes, Prejudice, and Discrimination

90.0K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Negative and Cognitive Symptoms of Schizophrenia01:30

Negative and Cognitive Symptoms of Schizophrenia

44
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,...

Forgetting01:21

Forgetting

56
Forgetting is an intrinsic aspect of human memory, characterized by the gradual loss or inaccessibility of information over time. Hermann Ebbinghaus, a pioneering psychologist, extensively studied this phenomenon and formulated the forgetting curve. This curve illustrates that memory loss occurs rapidly immediately after learning and then decelerates over time. Several mechanisms contribute to forgetting, including encoding failure, storage decay, retrieval failure, and interference.
Encoding...

科学领域:

  • 认知心理学 认知心理学
  • 神经科学是一个神经科学.
  • 发展心理学 发展心理学

背景情况:

  • 老年人经常表现出一种记忆积极效应 (MPE),记忆积极的信息比负面的信息更好.
  • 这种效应通常在显式记忆 (故意回忆/识别) 中观察到.
  • 以前的研究表明,MPE可能不在隐性记忆中 (无意召回).

研究的目的:

  • 在不同年龄组的暗示记忆中调查MPE.
  • 为了确定MPE是否存在于隐性记忆中,而在老年人显式记忆中缺席.

主要方法:

  • 对正,负和中性词的显式 (识别) 和隐式 (词识别) 记忆进行比较.
  • 招募了24名老年人 (66-85岁) 和24名年轻人 (18-37岁).

主要成果:

  • 年长的成年人表现出比年轻的成年人更低的识别准确性,没有明确的记忆MPE.
  • 两组人都最好地识别负面词.
  • 老年人表现出对积极和中性词语的隐性记忆 (原始化),与年轻人相似.
  • 年轻的成年人对负面词语表现出更强的隐性记忆,而年长的成年人对价值类型的隐性记忆没有差异.
  • 与年轻人相比,老年人对负面词语的隐性记忆有所减少.

结论:

  • 在老年人中观察到隐性记忆MPE,即使在显式记忆中缺席.
  • 衰老似乎会抑制负价值的隐性记忆,扩展与年龄相关的积极性框架.
