Actor-Observer Effect01:23

Actor-Observer Effect

503
The actor-observer effect, a cognitive bias closely linked to the fundamental attribution error, refers to the tendency for individuals to attribute their behavior to external, situational factors while explaining others’ behavior in terms of internal, dispositional traits. This asymmetry in attribution significantly influences social perception and judgment.Cognitive Mechanisms Behind the EffectTwo primary psychological mechanisms contribute to the actor-observer effect: differences in...

Naturalistic Observations

18.1K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

Impression Management Techniques IV: Altercasting

238
Altercasting is a strategic communication technique in which an individual imposes a specific identity or social role onto another person to influence their behavior and shape the interaction. By presuming a role—such as “responsible leader” or “patient person”—altercasting encourages the target to conform to that identity, often aligning their behavior with the expectations associated with the role. The power of this tactic lies in its subtlety; once a role...

Observational Studies

11.4K
Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...

Bystander Effect

10.4K
The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.

Framing Effects03:26

Framing Effects

8.1K
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...

Summary
This summary is machine-generated.

People can learn multiple, context-specific search templates for the same target. These specialized templates can be voluntarily switched based on expected context, aiding visual search efficiency.

Area of Science:

  • Cognitive psychology
  • Visual perception
  • Human attention

Background:

  • Repeatedly searching for a target in a specific context can lead to context-biased target templates.
  • The ability to form and utilize multiple context-specific templates for a single target remains an open question.

Purpose of the Study:

  • To investigate whether observers can develop and utilize multiple context-specific target templates for the same visual target.
  • To determine if observers can voluntarily switch between these learned templates based on contextual cues.

Main Methods:

  • A series of behavioral experiments were conducted.
  • Participants engaged in repeated visual search tasks across different contexts.
  • Data was collected on search performance and template switching behavior.

Main Results:

  • Observers demonstrated the capacity to learn multiple distinct target templates for a single target.
  • Participants could voluntarily switch between these context-biased templates according to expected environmental cues.
  • The coexistence of biased templates with an unbiased target representation was observed when templates were learned initially.

Conclusions:

  • The human visual system can flexibly adapt by forming multiple, context-specific representations of the same target.
  • Voluntary control over switching between these learned templates is possible, enhancing search efficiency in varying environments.
  • Initial learning of context-specific templates does not preclude the maintenance of a more general, unbiased target representation.
