    This memory is assists in allowing the computer to simultaneously read and write data at the same time. Simply put, RAM is the most common form of memory that is utilized by computers as well as other devices. There are specific types of RAM that include dynamic random access memory and static random access memory, or DRAM and SRAM respectively. These two RAM are very different in terms of how they allow data to be read and written. Dynamic random access memory is often considered the most frequent type found in computers. Static random access memory is also found in computer, and is usually referred to as the faster of the two types due to the fact that refreshing of this form of memory is not needed whereas with dynamic random access memory it is. The term RAM is often used to describe what the computer uses to function. It is the main memory or primary memory whereby all processes and software run.

  • Flashbulb Memories: Special Mechanism

    736 Words  | 2 Pages

    What do events like the assassination of John F. Kennedy, The Challenger space shuttle disaster, and hurricane Andrew that shook Miami have in common? All these events can be remembered by the people who experienced it due to flashbulb memory. Flashbulb memories were defined by R. Brown and J. Kulik (1977) as vivid, detailed, and long-lasting memories for attributes of the reception context of public news (Curci, A., & Lanciano, T., 2009). The people who experience such huge events are certain that their flashbulb memories are very accurate and can give in detail what occurred to them in those events (Schwartz, 2013). Furthermore events that generate flashbulb memories are usually very surprising and emotionally arousing and are perceived by the subject as personally consequential (Emotion & Memory 1993). But not all memories need to be negative and tragic. Events like the first day of first grade, your first romantic kiss, your first day at a new job, or recital of your wedding vows can also be described as flashbulb memories (Schwartz, 2013).

  • A Flashbulb Memory

    520 Words  | 2 Pages

    Have you ever experienced an event that was so significant to you that you felt as if your memory was taking a photograph, keeping the memory implanted in your brain for the rest of your life? This is a prime example of flashbulb memory. Flashbulb memory is a term that pertains to a person’s memory of hearing about extremely shocking events (Goldstein, 2011, p. 209). Flashbulb memory is not the memory for the event itself, but it’s the memory of how the person heard about the specific event (Goldstein, 2011, p. 209). This means that a flashbulb memory includes where you were and what you were doing when you found out about a tragic event (Goldstein, 2011, p. 209). Some key attributes of flashbulb memories are that they are both remembered for long periods of time and are exceedingly vivid (Goldstein, 2011, p. 209). A great way to describe flashbulb memories is to compare them to a photo that never fades, proving how relevant these memories are to those who have them (Goldstein, 2011, p. 209).

  • Exploring the Imperfection of Memory Recall

    995 Words  | 2 Pages

    In psychology we learned that you are never fully able to “vividly” recall memories, and that often times the memories you do recall are inaccurate. While I do not doubt my professor and her expert knowledge in her field, I truly do feel that there are a few memories I can vividly remember with precise detail. Flashbulb memories are the closest we can get to reliving an event, but even then these memories, while often referred to as “vivid” for lack of a better word, are still not completely accurate. The flashbulb memories I have of my favorite place feel factual rather than misconstrued, I know for a fact that these events happened, and it feels just as real as if they happened yesterday, but I am aware that logically I cannot know for sure
