Dissociative Amnesia
148
Dissociative amnesia is a complex psychological condition that manifests as an inability to recall personal information, often tied to traumatic or stressful events. Unlike general amnesia, individuals with this condition retain the ability to perform routine activities and procedural tasks, such as operating a phone or navigating public transportation, yet experience profound gaps in autobiographical memory. These lapses may encompass significant life events, such as suicide attempts or...

Dissociative Disorders
152
Dissociative disorders represent complex psychological conditions characterized by disruptions in consciousness, memory, identity, or perception. These disruptions cause individuals to experience a disconnection from their thoughts, emotions, and memories. The phenomenon is not merely an occasional lapse in attention but a profound alteration in mental functioning that can severely impact daily life.

Dissociative Identity Disorder
160
Dissociative Identity Disorder (DID), previously termed multiple personality disorder, is a complex psychological condition characterized by the presence of two or more distinct identities or personality states. Each identity exhibits unique patterns of behavior, voice, and mannerisms and may possess separate memories and emotional responses. The alternating control between identities can result in memory gaps and challenges in recalling daily activities, often exacerbating the individual's...

Amnesia
160
Amnesia is a condition marked by long-term memory loss, which impairs the ability to recall past events or create new memories.
The severity and duration of memory loss vary depending on the type and underlying cause. Amnesia is classified into two main types: retrograde and anterograde.
Retrograde amnesia is marked by the loss of memories formed before the onset of the condition. Patients may recall distant past events but often forget those occurring shortly before the incident.
Anterograde...

Interference and Decay
176
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...

Higher Mental Functions of Brain: Learning and Memory
894
Memory is one of the most vital higher mental functions of the brain. Memory is closely related to learning because it enables us to retain information and experiences from our past to use them in our present life. It also helps us to remember facts, events, and skills, such as riding a bike or swimming. There are two types of memory — declarative memory, which involves memorizing facts or events, and procedural memory, which enables us to remember how to do something like writing or...
