Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

2.5K
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

Lateralization01:28

Lateralization

1.2K
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

Motivational Bias01:25

Motivational Bias

461
Cognitive bias results from limitations in thinking and information processing, leading to systematic errors in judgment. Conversely, motivational bias stems from personal desires or emotions, causing distortions in perception to align with self-interest. Motivational bias influences how individuals perceive and attribute causes to events, often shaped by personal needs, goals, and self-esteem preservation. This bias can distort judgment, leading to inaccurate assessments of success, failure,...

Actor-Observer Effect01:23

Actor-Observer Effect

474
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...

Bias01:22

Bias

7.9K
Bias refers to any tendency that prevents a question from being considered unprejudiced. In research, bias occurs when one outcome or answer is selected or encouraged over others in sampling or testing. Bias can occur during any research phase, including study design, data collection, analysis, and publication.
In statistics, a sampling bias is created when a sample is collected from a population, and some members of the population are not as likely to be chosen as others (remember, each member...

The Anchoring-and-Adjustment Heuristic01:25

The Anchoring-and-Adjustment Heuristic

7.8K
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...

Summary
This summary is machine-generated.

The 3s Spreadsheet Test (3S Test) effectively identifies spatial neglect in stroke survivors, showing high sensitivity for both viewer-centered and stimulus-centered deficits. Further refinements are planned for this valuable assessment tool.

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Rehabilitation Medicine

Background:

  • Spatial neglect is a common and disabling deficit following stroke.
  • Cancellation tests are widely used to assess spatial neglect.
  • Existing tests may have limitations in differentiating neglect subtypes.

Purpose of the Study:

  • To evaluate the diagnostic utility of the 3s Spreadsheet Test (3S Test) for assessing spatial neglect.
  • To compare the performance of the 3S Test with a validated measure, the Apples Test.
  • To investigate the sensitivity of the 3S Test in identifying stimulus-centered and viewer-centered spatial neglect.

Main Methods:

  • The 3S Test, featuring high stimulus density and a low target-to-distractor ratio, was administered to 25 stroke survivors with left-sided neglect and 68 healthy controls.
  • Patients also completed the Apples Test for comparison.
  • Agreement between the 3S Test and Apples Test was assessed using kappa statistics.

Main Results:

  • All patients with neglect demonstrated abnormal performance on the 3S Test.
  • 91.7% of patients showed abnormal initiation, and 52.6% had prolonged completion times.
  • The 3S Test and Apples Test showed poor agreement in classifying neglect subtypes (κ = .25 and .05), but identified overlapping cases of bilateral neglect.

Conclusions:

  • The 3S Test is a sensitive tool for detecting both viewer-centered and stimulus-centered spatial neglect in stroke survivors.
  • The test's high sensitivity suggests its potential clinical utility in neglect assessment.
  • Ongoing development of the 3S Test version 2 aims to enhance its stimuli and scoring procedures.
