Decision Making: P-value Method

Decision Making: P-value Method

The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can have a...

Decision Making: Traditional Method

Decision Making: Traditional Method

The process of hypothesis testing based on the traditional method includes calculating the critical value, testing the value of the test statistic using the sample data, and interpreting these values.
First, a specific claim about the population parameter is decided based on the research question and is stated in a simple form. Further, an opposing statement to this claim is also stated. These statements can act as null and alternative hypotheses, out of which a null hypothesis would be a...

Decision Making

Decision Making

Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...

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 different ways based on the...

Impact of Schemas

Impact of Schemas

Schemas are cognitive structures that provide a framework for interpreting and organizing social information. They help individuals navigate complex environments by offering expectations about people, events, and behaviors. Schemas influence attention, encoding, and retrieval processes, thereby shaping the entire trajectory of information processing in social contexts.Attention and Cognitive LoadDuring initial attention, schemas function as filters that prioritize schema-consistent information,...

The Anchoring-and-Adjustment Heuristic

The Anchoring-and-Adjustment Heuristic

In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the $2,000...

Summary

This summary is machine-generated.

Attention and decision-making are linked in the brain. Parietal neurons involved in motor decisions also process attention, suggesting attention is a specialized decision process based on information utility.

Area of Science:

Neuroscience
Cognitive Science
Oculomotor System Research

Background:

Decision formation and attention are key cognitive processes for selecting actions and information, respectively.
While studied in the oculomotor system, a unified framework for both selection types is lacking.
Existing research highlights the oculomotor system's role in action and information selection.

Purpose of the Study:

To propose a unified view of decision formation and attention within the oculomotor system.
To explore the role of parietal neurons in both motor decisions and attentional selection.
To investigate how attention and motor decisions interact for effective oculomotor control.

Main Methods:

Review of existing neuroscientific evidence on parietal neuron activity.
Analysis of neural signals related to saccade motor decisions and perceptual selection.
Examination of attentional signals independent of action metrics, modality, and reward.

Main Results:

Parietal neurons encoding saccade motor decisions also exhibit attentional signals.
These attentional signals are independent of action-specific parameters like metrics, modality, and reward.
Evidence suggests attention functions as a specialized decision process prioritizing information utility.

Conclusions:

Oculomotor control relies on two interacting, distinct processes: attentional and motor decisions.
Attentional decisions assign value to information sources.
Motor decisions link selected information to actions, enabling flexible behavior.
