Types of Impact01:30

Types of Impact

658
Impacts can be classified in various forms, primarily under two subgroups: central impact and oblique impact. A central impact occurs when two objects collide head-on, possessing opposite velocities aligned along the line of impact. Conversely, an oblique impact occurs when two objects collide at an angle, resulting in a modification of both direction and velocity.
The coefficient of restitution is a metric for understanding the dynamics of impacts. It quantifies the ratio of relative velocity...

Framing Effects

7.5K
Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

Impact

198
Impact occurs when two bodies collide, leading to the application of impulsive forces between them. Analyzing impact mechanics involves considering two colliding particles moving along a line known as the line of impact, which passes through their centers and is perpendicular to the contact plane.
When particles with different initial velocities collide, they induce deformation by applying equal and opposite impulses. At the point of maximum deformation, the particles move together with...

Bullying

8.5K
A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is...

Bonanno's Theory of Grieving01:17

Bonanno's Theory of Grieving

176
Grieving is a complex psychological and emotional process that varies significantly among individuals. George Bonanno's research on bereavement identified four distinct patterns of grieving, offering a nuanced understanding of how people cope with significant loss, such as the death of a spouse, over extended periods. These patterns — resilience, recovery, chronic dysfunction, and delayed grief — highlight the diversity in emotional responses and adaptive mechanisms.

Fundamental Attribution Error01:14

Fundamental Attribution Error

13.3K
According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is...

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Affective Science

Background:

  • Recognition memory retrieval engages the striatum, potentially due to reward associations with remembering.
  • Previous research suggests memory retrieval might influence emotional valence, but the interaction with stimulus emotion is unclear.

Purpose of the Study:

  • To investigate how memory retrieval for negatively, neutrally, and positively valenced stimuli impacts subjective emotional experience.
  • To determine if accurate memory for stimuli consistently increases valence ratings.

Main Methods:

  • 47 healthy participants encoded negative, neutral, and positive pictures.
  • Participants completed a recognition memory test (identifying old vs. new items).
  • Subjective emotional valence was rated for each picture after the memory test.

Main Results:

  • Neutral and positive Hits (correctly identified old items) had higher valence ratings than Correct Rejections (CRs; correctly identified new items).
  • Positive False Alarms (FAs; incorrectly identified new items as old) also had higher valence ratings than CRs.
  • Negative Hits elicited lower valence ratings compared to negative CRs.

Conclusions:

  • The effect of memory retrieval on subjective experience is modulated by the emotional content of the stimuli.
  • Accurate memory for neutral stimuli enhances valence, while accurate memory for negative stimuli reduces valence.
  • Perceived oldness, regardless of accuracy, increases valence for positive stimuli.
