Summary
Crowding impairs object identification. This study shows crowding affects holistic face recognition, impacting both upright and inverted Mooney faces, suggesting multi-level visual processing.
Area of Science:
- Cognitive Psychology
- Neuroscience
- Visual Perception
Background:
- Object identification is hindered by nearby items, an effect known as crowding.
- Mooney faces, lacking explicit features, necessitate holistic processing for recognition.
Purpose of the Study:
- To investigate if crowding impacts holistic face representations using Mooney faces.
- To determine if crowding occurs within and between Mooney face representations.
Main Methods:
- Six experiments were conducted using Mooney faces as stimuli.
- The study examined crowding effects on Mooney face recognition, analyzing factors like flanker orientation and spacing.
Main Results:
- Crowding was demonstrated both within and between Mooney faces.
- Results met crowding criteria: eccentricity dependence, foveal sparing, critical flanker spacing, and asymmetry.
- Upright Mooney face recognition was more impaired by upright flankers than inverted ones.
Conclusions:
- Crowding can selectively occur between high-level representations of faces.
- Crowding appears to operate at multiple levels within the visual system.

01:20Mesh Analysis
Mesh analysis is a valuable method for simplifying circuit analysis using mesh currents as key circuit variables. Unlike nodal analysis, which focuses on determining unknown voltages, mesh analysis applies Kirchhoff's voltage law (KVL) to find unknown currents within a circuit. This method is particularly convenient in reducing the number of simultaneous equations that need to be solved.

01:30Oriented Surfaces
A surface is called orientable if a consistent choice of unit normal vector can be made at every point on the surface. A thin soap film stretched across a wire loop provides a familiar example. The film separates the air on one side from the air on the other, so one side can be selected as positive and the opposite side as negative. Once this choice is made, a unit normal vector can be assigned smoothly across the entire surface.At each point on the soap film, a unit normal vector points...
01:25Coplanar Forces
Consider an object upon which multiple forces are acting. If the lines of action of each force lie within the same plane, the system can be considered coplanar. The Cartesian vector form can be used to resolve each force into its respective components. For a coplanar system, the system will be in equilibrium if each component of the resultant force equals zero and the resultant force on the system is zero. If the sum of the forces is not equal to zero, then the object will not be in equilibrium...
01:09Turbulent Flow: Problem Solving
Carbonation is a process used to dissolve carbon dioxide gas in a liquid, commonly used in the production of carbonated beverages. Achieving efficient carbonation requires careful control of temperature, pressure, and flow conditions. By adjusting these parameters, carbonation efficiency can be maximized, producing a higher concentration of CO2 in the liquid.
Temperature is a key factor in CO2 solubility. In this case, the CO2 gas and the liquid are cooled to 20°C. Lower temperatures enhance...

01:18Mohr's Circle for Plane Strain
Mohr's circle is a crucial graphical method used to analyze plane strain by plotting strain on a set of cartesian coordinates, where the abscissa is normal strain ∈ and the ordinate is shear strain γ. Similarly to Mohr’s circle for plane stress, two points X and Y are plotted. Their coordinates are (∈x, -γXY) and (∈Y, γXY), respectively.
Mohr's circle visually represents the strain states under various conditions, which is essential for understanding material behavior. The center of Mohr's...

01:06Collisions in Multiple Dimensions: Problem Solving
In multiple dimensions, the conservation of momentum applies in each direction independently. Hence, to solve collisions in multiple dimensions, we should write down the momentum conservation in each direction separately. To help understand collisions in multiple dimensions, consider an example.
