Perception Attention And Memory Essay

Improved Essays
Perception, attention, and memory are slippery subjects. Perception is the process of recognizing and interpreting sensory stimuli, which is everything taken in through sight, sound, smell, touch and taste (Matlin, 2012). Consequently, it is an imprint that is left in the mind. Attention is the concept that refers to how specific information is processed in the environment (Matlin, 2012). It allows focus on specific items while filtering out other less significant stimuli. Memory is the process in which information is coded, stored, and retrieved. There is more than one type of memory, which again, can determine the capacity and duration for which we store what we have learned. Short-term memory has the most limitations; it is fragile and can be lost quickly. Of the two types of memory, long-term is essentially limitless and is accessed through three different types – semantic, procedural, and …show more content…
Memories of the initial event can be effected by events and suggestions that occurred afterwards also known as post event misinformation effect (Gerry et al, 2005). The particular way in which a question was asked, the type of feedback given, social pressure to do the right thing, and the time delay between the event and the testimony can all affect accurate information (Matlin, 2012). The relationship between eyewitness memory and recall is minimal. A person may appear confident in their memories, but actual recall of events is lacking. According to Wise as stated in Matlin’s Cognition, 8th edition “This research has practical applications for the legal system. For example, a survey of U.S. law enforcement officers showed that only about 21% of the officers were aware that memory confidence is not strongly correlated with memory accuracy”

    The term crime cannot be defined easily because it does not have one definition nor two; crime is a concept. Moreover, crime is based on a general notion of ideals formed by society, according to time and place (Friedman, 1993, 6). Society does not imply all individuals, the rich and powerful create the laws that compose certain acts as a crime and are then enforced by law enforcement (Friedman, 1993, 10). Thus, giving law enforcement control and power over all individuals. Their job is to protect and serve within their community.…

    Abstract Eyewitness misidentification is one of the leading causes of wrongful conviction. The correlation between confidence and memory, effects of stress on memory, and the accuracy of identification have been proven to be false. Research studies indicate that misinterpretation can occur in one of three stages of the memory process acquisition, retention, and retrieval which are not exempt to that of an eyewitness. This paper will speak on the validity of eyewitness testimonies in the judicial system. Eyewitness testimonies can have an impact on a jury, which are the persons/people that take on the role of sorting out credibility and making judgments based on witness statements on whether or not they are being truthful.…

    The testimony of an eyewitness during a court proceeding can have at times a positive implication and pave the way for justice to be served, but it may however also have detrimental repercussions for the accused. There are numerous instances upon which innocent suspects of crimes have been convicted of heinous crimes as a result of eyewitness misidentification. In serious crimes, eyewitnesses are used as a strong evidence of an event. However, we as humans are all prone to mistakes - mistakes in what we say, what we see and what we remember, and it is these mistakes which can have earth shattering effects on the accused perpetrators of crimes if there is an incorrect eyewitness. Though we may think our memories are spot on in areas such as…

    Eyewitness testimony is an account given by people of an event they have witnessed. It is the least reliable yet most relied on source of information that juries use. Even though eyewitness testimonies are generally unreliable, they do have a long history and are still used in court as official evidence; they also provide detailed insight to an event or incident with can help in investigations. Eyewitness testimony can help identify the possible suspects, especially when there is no video or audio recording evidence because it can construct a sequence of events. According to the theory of reconstructive memory people do remember the general occurrence of the event.…

    I. Research Question: Laura Smalarz and Gary L. Wells conducted a study, Post-Identification Feedback to Eyewitnesses Impairs Evaluators’ Abilities to Discriminate between Accurate and Mistaken Testimony. The main research question in this study was whether feedback interferes with evaluators’ abilities to discriminate between accurate and mistaken identification testimony. This study is interesting because many people have been wrongfully convicted because of mistaken eyewitness testimonies. This study tackles the question from the evaluator’s point of view and their ability to notice the difference between an accurate and a mistaken identification testimony. In the 1990’s they found that 75 % of the wrongful convictions were released due to DNA testing.…

    It is noted that there is limited research on situations in which a witness encounters misleading information after they have completed a cognitive interview, or CI where certain techniques are employed to elicit more accurate details in memory. This is an important point of research because the extensive literature on the misinformation effect shows that witnesses who have been exposed to misinformation may recall these misleading details during later testimony (Rivard, Lapaglia, Wilford, Chan, Fisher, 2013). Past research has indicated that taking an initial memory test can enhance one’s retention of learned material. For this study in particular, the purpose was to examine whether the cognitive interview, with all of its memory enhancing…

    In contrast, eyewitness testimonies can be unreliable. It is a process of recollecting memories, can contain biases, and the emotional state of the witness can affect their credibility. Individuals who become eyewitnesses have to recall their memories and unfortunately, memories can change over time. There is no guarantee that the witness will accurately remember the details. According to Loftus and Kelcham (1991), “every time we recall an event, we must reconstruct the memory, and with each recollection the memory can be changed”.…

    The aim of this study was to test the effect that schemas have on memory, eyewitness memory in particular. This was carried out by the replication of Loftus’s and Palmer’s (1974) study on schemas and eyewitness testimony. Participants in this study were high school students from the 11th grade that volunteered to take part in the experiment. This replication involved having participants divided into two conditions: the first condition would watch a video of an automobile accident, then would answer a questionnaire about the video, including a question that asked to estimate the cars’ speed when they smashed into each other; while the second condition would watch the same video and answer the same questionnaire, with the key difference being…

    Generally, memory is divided into three processes, which are sensory memory, short-term memory and long-term memory. Sensory memory store is the place in which sensory information is kept for few seconds or less. It happens quickly as well as fast decaying. For example, when you looking at an item and try to remember what it looks like just with a second of observation. Or it is even less than a second when you try to memorize the image that only holds for a very short time.…

    Suggestibility, as it pertains to memory, is a person’s unknown tendency to incorporate incorrect or misleading information into his or her own personal recollection of an event. Some contest that suggestion is a subset of misattribution, but this is not this case. Misattribution can occur without the presence of overt suggestion; this is not the case for suggestion. This finding places suggestion and its effects in a distinct class of its own. While the power of suggestion can be hard to understand for some, it becomes all too clear when suggestion is referenced in the context of the criminal justice system, where leading questions can lead to eyewitness misidentifications, suggestive recall procedures can produce false memories, and aggressive…

    After watching How reliable is your memory? by Elizabeth Loftus, I believe that to a great extent, memory is not a reliable source of knowledge because it can be distorted, contaminated, and even falsely imagined. Memory decay, distorted memory, hindsight bias, consistency bias, the availability heuristic bias and suggestibility- are all problems that beset our reliance on memory. “I was there. I saw it.”…

    There are three types of memory stores: sensory memory, short-term memory, and long-term memory. How we process memory to remember information is through three stages called encoding, storing, and retrieval. Sensory memory is your first initial process of when you perceive information that you do not retain. This type of memory relates to all the senses. For instance, iconic memory is when you receive information visually but only for a second, such as looking at a magazine and echoic memory is when information is received through the ears, like listening to talk radio and only remembering a few seconds of what was put…
