Cause and Effect

Cause and Effect

While variables are sometimes correlated because one does cause the other, it could also be that some other factor, a confounding variable, is actually causing the systematic movement in our variables of interest. For instance, as sales in ice cream increase, so does the overall rate of crime. Is it possible that indulging in your favorite flavor of ice cream could send you on a crime spree? Or, after committing crime do you think you might decide to treat yourself to a cone?

Actor-Observer Effect

Actor-Observer Effect

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...

The Placebo Effect

The Placebo Effect

The placebo effect occurs when people's expectations or beliefs influence or determine their experience in a given situation. In other words, simply expecting something to happen can actually make it happen.

Fundamental Attribution Error

Fundamental Attribution Error

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...

Framing Effects

Framing Effects

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...

Role of Affect in Interpersonal Attraction

Role of Affect in Interpersonal Attraction

Affect plays a crucial role in shaping interpersonal evaluations and perceptions. Emotions influence how individuals judge and respond to others, often determining whether interactions are viewed positively or negatively. This effect can manifest directly through interactions with the person in question or indirectly via associations with unrelated emotional experiences.Direct Effects of Affect on AttractionAffect directly influences interpersonal attraction when a person’s behavior...

Summary

This summary is machine-generated.

Attention may not manage neocortical resources but instead emerge from basal ganglia circuits. This value-based decision-making framework suggests attention filters sensory input by estimating environmental states.

Area of Science:

Neuroscience
Cognitive Science
Decision Making

Background:

Attention is traditionally viewed as crucial for managing limited sensory processing resources in the neocortex.
This perspective posits an alternative origin for attention, linking it to basal ganglia functions.

Purpose of the Study:

To propose and support an alternative framework where attention arises as a byproduct of value-based decision-making circuits.
To challenge the traditional view of attention's role in neocortical resource management.

Main Methods:

Review of physiological, anatomical, computational, and clinical findings.
Development of a novel theoretical framework linking decision-making to attention.

Main Results:

Evidence suggests that estimating environmental states, a key component of decision-making, underlies attention's filter-like properties.
The proposed model integrates basal ganglia circuitry with attentional mechanisms.

Conclusions:

Attention may be an emergent property of conserved basal ganglia circuits involved in decision-making, predating the neocortex.
This challenges the established role of attention in neocortical resource allocation.
