Summary
Spatial attention is not limited by eye movement range. This study found that visual attention can be directed to any location, regardless of oculomotor limitations or saccadic eye movements.
Area of Science:
- Neuroscience
- Cognitive Psychology
- Ophthalmology
Background:
- Previous studies suggested attentional deficits at locations outside the oculomotor range.
- Research often relied on reaction times to assess attention and eye movements.
Purpose of the Study:
- To investigate whether spatial attention is restricted by oculomotor range.
- To examine visual sensitivity at locations within and beyond the oculomotor range during fixation and saccade preparation.
Main Methods:
- Participants' head position was altered to limit saccadic eye movements.
- Visual sensitivity was measured using orientation discrimination of visual noise patches.
- Attentional cues were presented inside and outside the oculomotor range during fixation and saccade preparation.
Main Results:
- Attentional cues attracted visual attention irrespective of their location relative to the oculomotor range.
- No attentional benefit was observed at the saccade endpoint when the cue was unreachable.
- Spatial attention is not coupled to the executed oculomotor program.
Conclusions:
- Spatial attention can be deployed without restriction, even to locations unreachable by eye movements.
- Covert and overt attentional orienting may be guided by gaze control system feedback, independent of oculomotor limitations.

The range is one of the measures of variation. It can be defined as the difference between a dataset's highest and lowest values. For example, in the study of seven 16-ounce soda cans, the filled volume of soda was measured, thus producing the following amount (in ounces) of soda:
15.9; 16.1; 15.2; 14.8; 15.8; 15.9; 16.0; 15.5
Measurements of the amount of soda in a 16-ounce can vary since different subjects record these measurements or since the exact amount - 16 ounces of liquid, was not...

The relative amounts of reactants and products represented in a balanced chemical equation are often referred to as stoichiometric amounts. However, in reality, the reactants are not always present in the stoichiometric amounts indicated by the balanced equation.

01:29The Number e as a Limit
72
The number e is a fundamental constant in calculus, playing a central role in describing continuous change, particularly exponential growth. It is most naturally defined through its relationship with the natural logarithm, which is the inverse of the exponential function with base e. This relationship allows e to be characterized using basic principles of differentiation rather than as an arbitrary numerical constant.A key property of the natural logarithm function, ln x, is that its derivative...

01:27¹H NMR: Long-Range Coupling
2.7K
The coupling interactions of nuclei across four or more bonds are usually weak, with J values less than 1 Hz. While these are usually not observed in spectra, the presence of multiple bonds along the coupling pathway can result in observable long-range coupling.
In alkenes, spin information is communicated via σ–π overlap, as seen in allylic (four-bond) and homoallylic (five-bond) couplings. These coupling interactions are stronger when the σ bond is parallel to the alkene...

In the field of psychology, there are several ways to organize measurements of a trait, feature, or characteristic (i.e., variables). Qualitative data, such as ethnicity, can be tabulated into a frequency count to provide information about the proportion, as well as the variety of groups in a sample or population. On the other hand, researchers can perform a wider set of calculations on quantitative data. The mean, mode, and median, for instance, are central tendency measures to identify a...

01:13Angle of Twist - Elastic Range
781
Consider a cylindrical shaft with a length denoted by L and a consistent cross-sectional radius referred to as r. This shaft undergoes a torque at the free end. The highest shearing strain within the shaft is directly proportional to the twist angle and the radial distance from the shaft axis. When the shaft behaves elastically, this shearing strain can be articulated using variables such as the applied torque, radial distance, the polar moment of inertia, and the modulus of rigidity. By...
