Decision Making: Traditional Method

4.1K
The process of hypothesis testing based on the traditional method includes calculating the critical value, testing the value of the test statistic using the sample data, and interpreting these values.
First, a specific claim about the population parameter is decided based on the research question and is stated in a simple form. Further, an opposing statement to this claim is also stated. These statements can act as null and alternative hypotheses, out of which a null hypothesis would be a...

Decision Making01:20

Decision Making

186
Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...

Eyewitness Memory01:22

Eyewitness Memory

149
Eyewitness memory refers to the recollection of events by someone who has directly witnessed them, often serving as critical evidence in legal settings. This type of memory is commonly used in criminal cases where a witness describes details like a suspect's appearance, clothing, or behavior during a crime. However, despite its perceived reliability, eyewitness memory is prone to significant errors.
One such error is memory distortion, which occurs because human memory does not function...

Decision Making: P-value Method

5.6K
The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim  is also stated. These statements can act as null and alternative hypotheses:  a null hypothesis would be a neutral statement while the alternative hypothesis can...

Area of Science:

  • Forensic Science
  • Cognitive Psychology
  • Sensory Science

Background:

  • Forensic practice heavily relies on human interpretation of patterned evidence (e.g., tool marks, fingerprints).
  • Subjective comparisons by trained observers determine if evidence matches a source.
  • Concerns about wrongful convictions necessitate improved forensic methodologies.

Purpose of the Study:

  • To analyze the vulnerabilities inherent in current forensic pattern comparison disciplines.
  • To propose evidence-based strategies for enhancing the reliability of forensic pattern analysis.
  • To leverage principles from sensory science for objective forensic evaluations.

Main Methods:

  • Drawing upon established theoretical and empirical frameworks from sensory science.
  • Examining human information processing in the context of sensory measurement, discrimination, and classification.
  • Illustrating potential weaknesses in contemporary forensic comparison techniques.

Main Results:

  • Identified specific vulnerabilities in subjective pattern comparison within forensic science.
  • Demonstrated how sensory science principles can illuminate these weaknesses.
  • Outlined concrete strategies for improving the objectivity and accuracy of forensic analysis.

Conclusions:

  • Contemporary forensic pattern comparison methods possess inherent vulnerabilities.
  • Sensory science offers valuable insights and methodologies for strengthening forensic evaluations.
  • Implementing science-based improvements is crucial to reduce errors and enhance justice in forensic practice.
