| Discuss the motivational factors involved. | Conflicted roles(having multiple roles), emotion(anger leads to poor judgement), group membership(us vs them mentality), commitment(commit to previous actions) |
| What is the coherence effect? | bias where people tend to form internally consistent beliefs by exaggerating the strengths of supporting information and downplaying conflicting evidence , View evidence as a whole |
| Describe the mechanisms of biased reasoning. | Framing questions to confirm beliefs, only exposure to info that confirms hypothesis, only test/scrutinize info that goes against beliefs, biased view of the evidence, stopping once theres enough confirming evidence |
| What reforms should take place to improve the investigation process? | Debiasing, functional separation, restructuring, transparency |
| What are the various types of profiling? What are their limitations? | Criminal Profiling – Identifies characteristics of an offender based on the crime scene and behavior.Psychological Profiling – Focuses on the psychological state and traits of a suspect based on their behavior or personality. |
| What are the various types of profiling? What are their limitations? | Geographic Profiling – Uses location data of crimes to predict where an offender may live or work.Suspect-Based Profiling – Focuses on the characteristics of known offenders (e.g., age, race) to predict future crimes. |
| What are the various types of profiling? What are their limitations? | Behavioral Profiling – Examines patterns of behavior (e.g., in terrorism or criminal acts) to predict future actions |
| What are the arguments against criminal profiling? | Many assumptions have not been tested, crime scenes from the same killer might look different, behavior are the result of personality and situation, profile., characteristics are vague may apply to many ppl, tunnel vision for investigations |
| What are the misconceptions concerning profiling | Profilers predict personality, ptofilers solve crimes, profilers is an established scientific enterprise |
| What are the realities concerning profiling? | Questionable reliability & validity behavioral patterns are helpful, rarely solve crimes, need reliability & validity |
| What are the different characteristics/types of serial killers? | Visionary voices tell them to kill, mission-oriented kill ppl who they see evil/unworthy, hedonistic: kill for the thrill(sexual pleasure in killing) power oriented: satisfaction from capturing & controlling victim |
| What are psychological autopsies? What are the limitations? | Specialized procedure intended to provide insight into the mental state of a deceased person at the time of their death |
| How have researchers shown that memories can be altered by misinformation and suggestion? | Research shows memory can be altered through suggestive questioning and false information, as demonstrated in studies by Loftus and Palmer. |

| What type of reforms can be made to prevent innocent people from going to prison? | Reforms: Improved lineup procedures, better police training, corroborative evidence |
| What are system variables? | Controlled by legal system (e.g., lineup procedures). |
| Estimator variables | Inherent to the crime scene (e.g., lighting, stress |
| What is the post-identification feedback effect? | Witness confidence can be falsely inflated by confirming feedback. |
| What are double-blind lineups, | both the witness and the officer administering the lineup do not know who the actual suspect is |
| unbiased instructions, | Before viewing the lineup, witnesses are given instructions that help prevent false identifications |
| sequential | In a sequential lineup, witnesses are shown individuals one at a time, rather than all at once |
| simultaneous lineups? | all lineup members (fillers and the suspect) are presented at the same time. |
| Some other influences on eyewitness memory: | cross-racial identifications/own-race bias, weapon focus, emotion/stress |
| What is memory repression? | The controversial theory that traumatic memories can be buried in the subconscious. |
| How can guided imagery, self-help books, and hypnosis lead to false recovered memories? | by encouraging vivid mental visualization, suggestive questioning, and heightened imagination, making it harder to distinguish real memories from imagined ones. |
| What is the relationship between reported recovered memories and performance on the DRM? | People who report recovered memories are more prone to false memories in the DRM task, suggesting increased memory distortion and susceptibility to suggestion. |
| Explain the various components of the Cognitive Interview and how they improve recall. | Rapport building, free recall(report everything), eye closure(increase concentration, crude recall + follow up questions(use their laguage), |
| Explain the various components of the Cognitive Interview and how they improve recall. | recall in reverse order(may recall details they missed earlier, draw the scene (mental contex reinstatement), review the witness description |
| How are children typically interviewed? | Use of simple language, non-leading questions, and rapport-building techniques. |
