When a homogeneous list contains a few items that are different from the rest of the items in the list, these isolated items show enhanced recall compared to the same items in a list where these items are not isolated. This phenomenon, known as the isolation effect, has been explained on the basis of isolated items eliciting salience. In this experiment, negative pictures and neutral pictures were isolated at the early and late part of the list.

Article Synopsis
  • - The study examined how emotions affect memory, specifically how negatively arousing images impair the ability to recall whether items were meant to be remembered or forgotten.
  • - Participants viewed pictures that were negatively, positively, or neutrally arousing, followed by a "remember" or "forget" instruction, with recall of negatively arousing images being higher than the other types.
  • - Notably, negatively arousing images, especially violent ones, led to more mistakes in identifying whether the images were meant to be remembered or forgotten, suggesting that negative emotions can disrupt source memory, although it's unclear if this happens during memory encoding or retrieval.

Christianson (1992) proposed two mechanisms to explain emotionally enhanced memory: preattentive processing and poststimulus elaboration. Experiment 1 examined these processes by instructing participants to perform (1) a concurrent distractor task, (2) a continuous distractor task, or (3) both while viewing the negatively arousing, positively arousing, and neutral pictures. Recall of negatively arousing pictures showed a small decline in one of the distractor conditions, indicating that elaboration plays a minor role in remembering these pictures.

Juveniles are more likely than adult offenders to commit crimes in groups. This tendency makes the juvenile offender more susceptible to the felony murder rule. In three experiments we tested the notion that juveniles arrested and charged under the felony murder rule would be transferred into the adult criminal justice system based on an equalistic (i.

The purpose of the investigation was to examine the influence of the victim's provocation and hopefulness on the sentencing of a husband convicted of domestic violence. It was hypothesized that mock jurors would assign less-severe sentencing if the victim was provoking and hopeful. Mock jurors read one of four factorial court case combinations of provocation and hopefulness and rendered an individual predeliberation sentence and a group postdeliberation sentence.
