Summary
The Self-perception of Text-message Dependency Scale (STDS) is a valid tool for measuring texting dependence in US adults. Higher STDS scores correlate with increased motor vehicle accidents and moving violations.
Area of Science:
- Psychology
- Public Health
- Transportation Safety
Background:
- Text messaging behavior is sometimes characterized as addictive, but reliable measurement tools are lacking.
- The Self-perception of Text-message Dependency Scale (STDS) is one such tool, but its validation has been limited to Japanese youth.
Purpose of the Study:
- To evaluate the psychometric properties of the STDS in a US adult population.
- To assess the STDS's correlation with driving-related outcomes, specifically motor vehicle accidents (MVAs) and moving violations.
Main Methods:
- A sample of 468 US adults (ages 18-74) completed the STDS via Amazon's Mechanical Turk.
- Participants reported their history of MVAs and moving violations within the past year.
Main Results:
- Confirmatory factor analysis supported the original factor structure of the STDS.
- The STDS scores significantly correlated with both the number of MVAs and moving violations.
Conclusions:
- The STDS is a psychometrically sound instrument for assessing texting dependence among US adults.
- The STDS demonstrates utility in predicting risky driving behaviors, including MVAs and moving violations.

The International System of Units or SI system, by international agreement, has fixed measurement units for seven fundamental properties: length, mass, time, temperature, electric current, amount of substance, and luminosity. These are called the SI base units.

Hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as determined by the ion product of water (Kw). The concentrations of these ions in a solution are often critical determinants of the solution’s properties and the chemical behaviors of its other solutes. Two different solutions can differ in their hydronium or hydroxide ion concentrations by a million, billion, or even trillion times. A common means of...

Subliminal perception refers to the processing of sensory information that occurs below the level of conscious awareness. Researchers study subliminal perception by presenting a stimulus, such as a word or image, very quickly, typically around 50 milliseconds. This rapid presentation is often followed by another stimulus, such as a pattern of dots or lines, which blocks further mental processing of the initial stimulus. As a result, if participants cannot identify the initial stimulus better...

01:25Factors Affecting Perception
2.8K
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.

Perception is a fundamental psychological process that enables individuals to organize, interpret, and consciously experience sensory information. This process is crucial for understanding and interacting with the world around us. It includes both bottom-up and top-down processing, each playing a distinct role in how we perceive our environment.
Bottom-up processing begins at the sensory level, where receptors detect external environmental stimuli. These could include the tactile sensation of...

Every measurement provides three kinds of information: the size or magnitude of the measurement (a number), a standard of comparison for the measurement (a unit), and an indication of the uncertainty of the measurement. While the number and unit are explicitly represented when a quantity is written, the uncertainty is an aspect of the errors in the measurement results.
