Competition

Competition

When organisms require the same limited resources within an environment, they may have to compete for them. Competition is a net-negative interaction. Even if two competing individuals or populations do not interact directly, the overall fitness of both competitors is lowered as a result of not having full access to the limited resource.

Anatomical Movements

Anatomical Movements

Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist,...

The Movement of Organelles and Vesicles

The Movement of Organelles and Vesicles

In eukaryotic cells, cytoskeletal filaments such as actin, microtubules, and intermediate filaments form a mesh-like cytoskeletal network. These filaments serve as tracks for transporting cellular cargo. Specialized motor proteins use the chemical energy stored in adenosine triphosphate (ATP) for this transport. During interphase, microtubules are polarized, with the plus-end towards the cell periphery and the minus-end towards the cell center. Two microtubule-associated motor proteins,...

Attention-Deficit/Hyperactivity Disorder

Attention-Deficit/Hyperactivity Disorder

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....

Fluid Movement Between Compartments

Fluid Movement Between Compartments

The force applied by fluids against a surface, known as hydrostatic pressure, initiates the transfer of fluid among different compartments. Within our blood vessels, the blood's hydrostatic pressure is a result of the heart's pumping action. At the arteriolar end of capillaries, hydrostatic pressure (capillary blood pressure) exceeds the opposing colloid osmotic pressure created primarily by plasma proteins like albumin. This discrepancy in pressure propels plasma and nutrients from the...

Movement Joints in Buildings

Movement Joints in Buildings

Movement joints in buildings are essential design elements that accommodate inevitable motions caused by various factors such as temperature changes, moisture content variations, and structural deflections. These motions, if not considered in design and construction, can lead to unsightly or dangerous damage. Movement joints are incorporated in different forms to manage these stresses and allow materials to move without causing distress.
The simplest type of movement joints, working joints, are...

Summary

Objects compete for visual recognition across eye movements, but only when task-relevant. This competition impacts attentional processing, influencing how we recognize items after saccadic eye movements.

Psychology

Background:

Human behavior relies on visual object recognition, which is resource-limited.
Objects in view compete for attentional processing, reducing recognition performance with increased competition.

Purpose of the Study:

To investigate whether object competition for attention extends across saccadic eye movements.
To determine if task relevance modulates cross-saccadic object competition.

Main Methods:

Participants performed saccades to a target, followed by brief letter presentation and masking.
The number of presaccadic non-target objects (0, 2, or 4) was manipulated.
Object recognition performance was measured by participant reports, with task relevance varied.

Main Results:

Task-irrelevant presaccadic objects did not affect postsaccadic recognition.
Postsaccadic object recognition performance decreased as the number of task-relevant presaccadic objects increased.
This effect was attributed to slowed and delayed visual processing post-saccade.

Conclusions:

Objects compete for recognition across saccades, but this competition is contingent on task relevance.
Findings reveal a task-driven attentional mechanism in object recognition integrated with saccade-mediated vision.
