The Availability Heuristic01:08

The Availability Heuristic

A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):
Social Facilitation01:04

Social Facilitation

Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.
Law of Independent Assortment02:03

Law of Independent Assortment

While Mendel’s Law of Segregation states that the two alleles for one gene are separated into different gametes, a different question of how different genes are inherited remains. For example, is the gene for tall plants inherited with the gene for green peas? Mendel asked this question by experimenting with a dihybrid cross; a cross in which both parents are homozygous for two distinct traits resulting in an F1 generation that are heterozygous for both traits.

Serial Position Effect01:03

Serial Position Effect

The serial position effect is a cognitive phenomenon where individuals are more likely to recall the first and last items in a list compared to those in the middle. This effect is divided into the primacy effect and the recency effect. The primacy effect is observed when the initial items in a list are remembered better. This occurs because these items are rehearsed more frequently or receive more elaborative processing, allowing them to be encoded into long-term memory more effectively. For...
Wilcoxon Signed-Ranks Test for Matched Pairs01:09

Wilcoxon Signed-Ranks Test for Matched Pairs

The Wilcoxon signed-rank test for matched pairs evaluates the null hypothesis by combining the ranks of differences with their signs. It essentially tests whether the median of the differences in a population of matched pairs is zero. Since the test incorporates more information than the sign test, it generally yields more trustable conclusions. This test also does not require the data to follow a normal distribution, but two conditions must be met for it to be applicable: (1) the data must...

Summary

Eyewitness lineup procedures, sequential versus simultaneous, were compared in a large study. Results suggest no strong preference for either method when considering real-world lineup characteristics.

Area of Science:

  • Forensic Psychology
  • Criminal Justice Research

Background:

  • A growing movement advocates for sequential eyewitness lineups over simultaneous ones.
  • The effectiveness of sequential versus simultaneous lineup procedures remains a subject of debate.

Purpose of the Study:

  • To empirically compare the performance of sequential and simultaneous eyewitness identification procedures.
  • To investigate potential advantages of sequential lineups in a large-scale study.

Main Methods:

  • Conducted a large study with 2,529 participants comparing sequential and simultaneous lineup procedures.
  • Performed 24 direct comparisons between the two lineup methods.
  • Utilized a liberal statistical criterion initially, then adjusted for multiple comparisons.

Main Results:

  • A liberal criterion showed few significant differences; some advantages for both sequential and simultaneous lineups were observed under specific photographic position conditions.
  • After adjusting for multiple tests, no significant advantages for sequential lineups were found.
  • No evidence supported the claim that sequential lineups offer an advantage due to a more conservative response criterion.

Conclusions:

  • The study found no strong evidence to prefer sequential over simultaneous eyewitness lineups in general.
  • The optimal lineup procedure may depend on specific characteristics not universally present in real-world cases.
  • Further research may be needed to identify specific conditions under which one lineup method outperforms the other.
