Key Terms to Review (22)
Confabulation: Confabulation is a memory error characterized by the fabrication of false memories without the intention to deceive. It occurs when individuals unknowingly create distorted or misinterpreted memories to fill in gaps in their recollection, often leading to a mixture of real and imagined events. This phenomenon is particularly relevant in discussions of memory distortions and certain memory disorders, as it highlights the complexities of how memories can be influenced by various factors.
Confirmation bias: Confirmation bias is the tendency to search for, interpret, favor, and recall information in a way that confirms one's preexisting beliefs or hypotheses. This bias can significantly affect various cognitive processes, leading individuals to overlook contradictory evidence and reinforcing their current perspectives.
Cultural influences: Cultural influences refer to the ways in which the values, beliefs, customs, and practices of a society shape the behaviors, perceptions, and thought processes of individuals within that culture. These influences can affect how people remember information, categorize concepts, and perceive others, often guiding their interpretations and interactions in various social contexts.
Decay Theory: Decay theory suggests that memories fade over time due to the passage of time and the lack of use or rehearsal. This concept implies that if information is not actively maintained or retrieved, it will eventually become inaccessible or lost, highlighting the transient nature of short-term memory and the factors that contribute to forgetting.
Déjà vu: Déjà vu is the uncanny sensation of having experienced a situation before, despite the fact that it is happening for the first time. This phenomenon often triggers a sense of familiarity, leading individuals to believe they have previously lived through the current moment, which raises intriguing questions about memory processing and its potential distortions.
Eyewitness testimony: Eyewitness testimony refers to the account given by individuals who have witnessed an event, often used in legal contexts to help establish facts about a crime or incident. This type of testimony can be crucial for court cases, but it is also highly susceptible to inaccuracies and distortions due to various psychological factors. The reliability of eyewitness accounts can be significantly impacted by attention-related phenomena and memory processes, which can alter what a witness believes they saw or experienced.
False memories: False memories are recollections of events that either did not occur or occurred differently than remembered. They illustrate how our memories are not always accurate and can be influenced by various factors such as suggestion, misinformation, and the passage of time, leading to significant memory distortions.
Implanted memories: Implanted memories refer to false or distorted recollections of events that an individual believes to be true, often created through suggestions or misinformation. These memories can arise from various sources, such as leading questions, social pressure, or exposure to misleading information, and they highlight the malleability of human memory and its susceptibility to distortion.
Interference Theory: Interference theory posits that forgetting occurs because memories compete with one another, leading to confusion and distortion of recall. This theory suggests that there are two main types of interference: proactive interference, where older memories disrupt the retrieval of newer ones, and retroactive interference, where new information hinders the recall of older memories. Understanding this theory is crucial for analyzing how memory can be affected by various factors, leading to distortions in recollection.
Media influence: Media influence refers to the significant impact that various forms of media, such as television, social media, and news outlets, can have on public perception, behavior, and memory. It shapes how individuals recall events, understand social norms, and interpret information, often leading to memory distortions and altered beliefs about reality. This influence plays a critical role in shaping societal attitudes and can result in the creation of false memories or changes in existing memories based on media portrayals.
Memory distortion: Memory distortion refers to the phenomenon where a person's recollection of an event is altered or misremembered, leading to inaccuracies in the details of the memory. This can occur due to various factors, such as misinformation, suggestion, or the incorporation of new information into existing memories. Memory distortion highlights the malleable nature of memory and raises questions about the reliability of eyewitness testimony and personal recollections.
Memory reconstruction: Memory reconstruction is the process through which memories are actively reconstructed rather than passively retrieved, involving the integration of new information, prior knowledge, and personal experiences. This reconstructive nature of memory can lead to distortions, making memories vulnerable to inaccuracies as they may be influenced by external factors like suggestion or misinformation.
Misinformation effect: The misinformation effect occurs when a person's memory of an event becomes less accurate due to the introduction of misleading information after the event has taken place. This phenomenon highlights how memory is not a perfect recording of experiences but is susceptible to distortion and alteration. It demonstrates that what we remember can be influenced by external factors such as suggestions, leading questions, or media reports, ultimately impacting the reliability of eyewitness testimony and personal recollections.
Motivated forgetting: Motivated forgetting is a psychological phenomenon where individuals intentionally or unconsciously suppress memories that are distressing or anxiety-provoking. This process often occurs as a defense mechanism to protect one’s emotional well-being, allowing individuals to avoid the discomfort associated with recalling painful experiences. The concept is closely linked to the idea of memory distortions, as the act of forgetting can alter one’s narrative and impact overall memory accuracy.
Proactive Interference: Proactive interference occurs when previously learned information hinders the ability to learn or recall new information. This phenomenon is particularly relevant in understanding how memory works, as it highlights the challenges faced during encoding and retrieval processes, especially when similar information is involved. Proactive interference illustrates how older memories can overshadow newer ones, impacting overall memory performance and contributing to the complexity of forgetting and memory distortions.
Repression: Repression is a defense mechanism in psychology where an individual unconsciously pushes distressing thoughts, memories, or feelings out of conscious awareness. This mechanism can lead to forgetting or memory distortions, as the repressed content is not accessible for reflection or processing, which can also affect emotional well-being and behavior. Understanding repression helps in exploring how traumatic experiences might be handled by the mind, often resulting in significant impacts on a person's memory and perception.
Retroactive interference: Retroactive interference is a memory phenomenon where new information interferes with the retrieval of previously learned information. This process can lead to forgetting past memories as they become harder to access due to the presence of newer material that competes for cognitive resources, affecting both short-term and long-term memory. Understanding this concept is crucial in exploring how memories are encoded, stored, and retrieved, as well as recognizing the factors that contribute to memory distortions.
Schema-consistent memory bias: Schema-consistent memory bias refers to the tendency for individuals to recall information that aligns with their existing mental frameworks or schemas, often leading to distorted or selective memories. This cognitive phenomenon highlights how our understanding of the world influences the encoding and retrieval of memories, resulting in a biased recall that favors schema-consistent details while neglecting or altering schema-inconsistent information.
Schemas: Schemas are cognitive frameworks or structures that help individuals organize and interpret information based on prior knowledge and experiences. They play a crucial role in how we process new information, as they allow us to make sense of the world by providing a mental shortcut for understanding complex situations. By influencing memory retrieval and perception, schemas can both aid in learning and contribute to misunderstandings, particularly in situations involving memory distortion or forgetting.
Source monitoring errors: Source monitoring errors occur when a person mistakenly attributes a memory to the wrong source, leading to confusion about where or how the information was acquired. These errors highlight the complexities of memory retrieval and how it can be influenced by external factors like suggestions or misinformation, ultimately resulting in distortions in recollection.
Stereotypes: Stereotypes are oversimplified and widely held beliefs or ideas about a particular group of people, which can lead to generalized perceptions and assumptions that do not reflect individual differences. They shape how we interpret social information, influencing memory, person perception, and attitudes toward others, often resulting in biases in our judgments and interactions.
Suppression: Suppression is the conscious effort to avoid or inhibit the recollection of unwanted memories or thoughts. This process plays a significant role in how we manage distressing or uncomfortable information, often leading to altered memory recall and can contribute to forgetting. By actively choosing not to think about certain memories, individuals may inadvertently distort their memory processes.
