Summary
People’s decision-making involves shifting attention, favoring options viewed longer and sooner. Sequential sampling models explain this, highlighting attention’s role in amplifying evidence for choices.
Area of Science:
- Cognitive Psychology
- Neuroscience
- Decision Science
Background:
- Decision-making involves attention allocation between stimuli.
- Sequential sampling models posit evidence accumulation proportional to subjective value, amplified by attention.
- Prior research supports a causal link between attention and choice.
Purpose of the Study:
- To review the role of attention in decision-making.
- To explore factors influencing attention during choice.
- To examine attentional effects in various choice paradigms.
Main Methods:
- Review of existing literature on attention and choice.
- Analysis of sequential sampling models.
- Discussion of findings from two-alternative, multi-attribute, and multi-alternative choice studies.
Main Results:
- Attention significantly influences choice outcomes.
- Attention is directed towards more salient or noisier stimuli in two-alternative choices.
- Higher-value options attract more attention in multi-alternative choices.
Conclusions:
- Attention is a critical component of the decision-making process.
- Understanding attentional drivers is key to refining choice models.
- Future research should further elucidate the interplay between attention and value in complex decisions.

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...

Accountability in nursing is a fundamental principle that underscores the obligation of nurses to take responsibility for their actions and answer for any errors or omissions in patient care. This principle is grounded in the professional, legal, and ethical frameworks that shape nursing practice. For instance, nurses must adhere to all relevant laws, regulations, and practice standards, including guidelines set forth by nursing boards and professional bodies, to ensure their actions comply...

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...

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....
