Recommended: Research proposal on stress and memory loss
1. Identify and define the mental processes that account for mistakes in identifying strangers. Also identify the circumstances that affect the accuracy of perceptions in identifying strangers.
1. Acquisition of memory- for the amount of information from the person during the time of the issues or crime activity.
2. Retrieval of the memory- the information that call be recalled at the time of the line-up
3. Retention of the memory- the information between the crime and the booking process to the line-up.
The five circumstances that affect accuracy of perceptions in identifying strangers is: the distractions, the focus, the stress on the witness, races of the two both strangers and the witness, and the length of time to sit and observe the stranger.
2. Why are photo identifications the most unreliable eyewitness identification procedure?
They photos can be unreliable

due to the fact that suspect can change their identity from the last time that person had their booking picture taken. 3. Identify and explain the rationales behind the three justifications for the exclusionary rule. Which justification does the U.S. Supreme Court use today? The three justifications for the exclusionary rule are: Constitutional rights against unreasonable seizure and coerced confession and certain amendment would not be of any use without the exclusionary rule. Judicial integrity forbids the courts from doing anything unconstitutional. Deterrence prevents crime control against the officials from breaking the law. The justification used today is the reasonable and good faith exceptions. 4.
List and explain five exceptions to the exclusionary rule.
Collateral use, is illegally obtained evidence is admissible in all no trial, Cross examination, the prosecution can use illegally obtained evidence to impeach defense, Attenuation of the taint of unconstitutional conduct, states that tainted evidence, Inevitable discovery is tainted evidence admissible if police law breaking produced the evidence and finally, good faith exception. Where State agents acting in good faith honestly believed they were complying with the Fourth Amendment.
5. Identify the difference between the subjective and objective tests of entrapment. Identify two elements in the subjective test of entrapment and the two kinds of circumstances the government can use to prove defendants' predisposition to commit crimes. The subjective version of the defense has a two-part structure. In most courts employing the subjective version, a defendant wishing to assert entrapment must first establish by a preponderance of the
evidence that a government agent “induced” him to commit the crime he or she is charged
with. 6. Is there a constitutional right to the exclusionary rule and the defense of entrapment? Explain your answer. There is no mention of the exclusionary rule and the defense of entrapment. Judges will figure out ways or think up ways to fit whatever for each case to each situation. 7. Identify the two elements of the qualified immunity defense, and explain why the test is so easy for officers to pass. “Objective legal reasonableness” where the actions meet or can’t be personally held liable. Also the other one is the reason will add up to the legal rules when the officer acted or “clearly established”. 8. Identify and describe the differences between two kinds of state civil lawsuits against individual state officers. State torts have individual officers with the civil rights act, lawsuits involve agencies and State torts and United States Act lawsuits. 9. Can you sue a judge for damage? A prosecutor? Explain. You can sue prosecutors but you cannot sure a judge because judges have what is called “absolute immunity”, but they can be voted out or impeached like the president. Prosecutors are usually protected by what is called “functional immunity” depending on what was the function of that case they were involved in.

For purposes of entrapment defense, a defendant’s conduct is the product of a law enforcement officer when the officer plays a direct role in influencing the defendant to engage in the conduct through an explicit order. Albaugh v. Ind., 721 N.E.2d 1233 (Ind. 1999).
“Accuracy-confidence correlation: an eye witnesses’ stated confidence is not a good predictor of identification accuracy; Stress effects: highly stressful situations may make an experience seem especially vivid, but such stressors can reduce the ability to recall details about a person’s face…Cross-race bias: eye witnesses are more accurate at identifying members of their own race than members of other races.”
In situations when a high profile case is public, police investigators undergo amounts of severe pressure to convict a suspect and is often led to convict the first suspect who is involved. Pressure from victims, the community, media and police supervisors often induce speed as the overriding factor when investigating a case. Police officers have human tendencies when trying to reach the overall goal of justice when solving a case. Tunnel vision is often the result of police officers having a narrow theory towards a suspect, drawn to conclusions about who is responsible early and disregarding evidence that points to the suspect as innocent.

Memory is an important and active system that receives information. Memory is made up of three different stages sensory memory, short term memory, and long term memory. According to the power point presentation, sensory memory refers to short storage of memory that allows an individual to process information as it occurs. Short term memory refers to memory that is only available for a limited time. It is information that is held for seconds or sometimes even minutes. Long term memory refers to memory that is stored for a long period of time and it has an unlimited capacity with the ability to hold as much information as possible. Retrieval is key and it allows individuals to have memories. Episodic memory refers to memory for events that we
The second stage of memory processing is storage. Aronson et al. (2013) defines storage as the process by which people store the information they just acquired. Unfortunately, memories are affected by incoming information through alteration or reconstruction. This phenomenon is referred to as recon...
Other factors to consider are the body language of an officer administering a lineup, as well as psychological influences such as witness recollection merging over time with the original event. Our minds are highly susceptible to suggestion, a police officer unknowingly leading us to a picture in a lineup, as they know the history of the people shown in the lineup. Over time we become more certain in the identification we made, as our recollection merges with the original
256, Spielman). Inaccurate eyewitness identifications can confound investigations from the earliest stages. Critical time is lost while police are distracted from the real perpetrator, focusing instead on building the case against an innocent person” (Sheck, InnocenceProject.com). So the question arises “how reliable would you predict an eyewitness’s testimony of a crime to be”? Well, the eyewitness can have several factors that indicate their decisions. These factors include misinformation, imagination, and things such as amnesia. With that being said, misinformation can be very misleading, this means that an eyewitness can identify a potential suspect with the wrong information. The eyewitness can have a full description of the potential suspect, however, some of the information they have may be misinterpreted or ultimately wrong. What I mean by this is that at first they may have said that the suspect was a “different height, weight, age range, hair color, etc.” (Sheck,
But rarely few researches have been focused on witness memory for firearms. As a matter of fact, firearms usually represent a significant factor for law enforcement in the present judicial system. For making police or other investigators to get the weapon information correctly and efficiently, some researchers conducted a study (Sharps et al. 2015), which was aimed to discover whether typical questioning patterns would affect the results of the memory test of eyewitnesses, who could recall the firearms evidence in some certain crimes, which may potentially assist investigators to identify the criminals. The study was basically separated into two major sections, one was the free recall stage and another was specific-information recall stage. As a result, these researchers have found that, even though there was no significant difference they thought it would be observed in specific response section, the significant result was observed in the free recall stage. Researchers concluded that they could get the more accurate testimony of the given firearms in the free recall stage rather than they could get in the condition of specific questioning. By focusing on not outlaws, but firearms, this study has shown a new potential way to get required evidences. Based on this idea, researchers have analyzed that the
In the article, “The Critical Importance of Retrieval For Learning” the researchers were studying human learning and memory by presenting people with information to be learned in a study period and testing them on the information that they were told to learn in order to see what they were able to retain. They also pointed out that retrieval of information in a test, is considered a neutral event because it does not produce learning. Researchers were trying to find a correlation between the speed of something being learned and the rate at which it is forgotten
Retrieval inhibition is the phenomenon of selectively retrieving only some aspects of a memory while inhibiting recall of other aspects. In Chapter 7 Eyewitness Identification and Testimony, for example a “recall of a crime scene may be altered depending on how the eyewitness is initially questioned. In one laboratory study, people looked at slides of a student dorm room that had been burglarized. Experimenters later used selective questioning when asking about details of the crime scene. Although there were many textbooks in the picture of the room, experimenters asked only about particular types of sweatshirts. When questioned at a later time about what they saw, people tended to have good recall of the sweatshirts but poor recall of other objects, such as textbooks. Retrieving memories of sweatshirts made it more difficult to recall aspects of the scene about which no questions were initially asked.” (Costanzo
with police spies (McAdams,2005). States and federal courts regulate under over operations y using the entrapment defense which excuses a person who committed an offense due to the encouragement of law enforcement from any criminal accountability (Dillof, 2004). The main focus of the entrapment defense isn’t to determine if a criminal act has taken place, but whether police involvement caused a person to commit a criminal act. This is the area in which the operations become cloudy.
Memory is the tool we use to learn and think. We all use memory in our everyday lives. Memory is the mental faculty of retaining and recalling past experiences. We all reassure ourselves that our memories are accurate and precise. Many people believe that they would be able to remember anything from the event and the different features of the situation. Yet, people don’t realize the fact that the more you think about a situation the more likely the story will change. Our memories are not a camcorder or a camera. Our memory tends to be very selective and reconstructive.
In this study, witnesses viewed a crime video and attempted to identify the culprit from a group line-up that did not actually have the culprit present. 253 mistaken-identification eyewitnesses were randomly given confirming, disconfirming, or no feedback regarding their description of the culprit or the culprit’s identification. The feedback process was either immediate or delayed for 48 hours, and measures were also immediate or delayed for 48 hours. It was shown that those who were given confirming feedback gave more distorted information. They had increased confidence in remembering what had happened, were able to make out facial details and their length of time to identify the culprit changed. There was also no difference in their statements when they were asked immediately or after 48 hours. Those who received disconfirming feedback were not so confident and took longer time to identify the culprit.
