Summary
Pathological Internet use creates a self-related processing bias, impacting cognitive control. This study reveals differences in self-related stimulus processing between those with problematic internet habits and typical users.
Area of Science:
- Cognitive Psychology
- Neuroscience
- Internet Addiction Research
Background:
- Problematic Internet use is associated with altered cognitive processes.
- Understanding self-related biases is crucial for explaining Internet addiction mechanisms.
Purpose of the Study:
- To investigate self-related processing biases in pathological Internet users compared to ordinary users.
- To explore the influence of self-related stimuli on cognitive control and response times.
Main Methods:
- An implicit priming task involving self/other related words and online image stimuli.
- Behavioral measures (response time) and electroencephalography (EEG) recording of event-related potentials (ERPs).
Main Results:
- Pathological Internet users exhibited longer response times and larger N2 amplitudes in self-related conditions, indicating altered self-processing.
- Both groups showed longer response times for self-related stimuli, but pathological users responded faster overall.
- Late Positive Component (LPC) amplitudes were smaller in self-related conditions, suggesting effects on inhibition and retrieval.
Conclusions:
- Pathological Internet use is linked to a distinct self-related processing bias.
- Internet use impacts inhibition control for self-unrelated stimuli and automatic retrieval of self-related stimuli.

02:55The Evidence for Evolution
48.1K
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

01:15Causes of Social Behavior II: Cognitive Processes
203
Cognitive processes affect social behavior by guiding how individuals perceive, interpret, and respond to social stimuli. These mental processes enable individuals to assess others' behaviors, attribute causes to their actions, and form expectations based on past experiences.Causes of Behavior and Social JudgmentsIndividuals determine the causes of others' behaviors by distinguishing between personal traits and external circumstances. For example, if a friend frequently arrives late, an...

01:28Causes of Social Behavior III: Biological and Environmental Influences
296
Social behavior is a complex phenomenon that arises from the interaction between biological predispositions and environmental influences. This intricate interplay shapes how individuals think, feel, and act in various social contexts. Understanding these mechanisms requires insights from psychology, neuroscience, genetics, and evolutionary theory.Environmental Influences on Social BehaviorEnvironmental factors, including temperature, odors, and visual stimuli, play a crucial role in shaping...

01:28Automatic Processing and Automatic Social Behavior
252
Automatic processing refers to the cognitive operations that occur without conscious intent or awareness, playing a fundamental role in shaping social cognition and behavior. These processes enable individuals to navigate complex social environments efficiently by relying on mental shortcuts and pre-existing knowledge structures known as schemas. One of the most influential mechanisms underlying automatic processing is priming, which subtly activates mental representations through exposure to...

00:54What is Behavior?
10.3K
Behaviors are actions that an organism engages in—they can be related to finding food, reproducing, defending against threats, and many other possible actions. Behaviors include activities related to the environment around the animal—such as migration—as well as social interactions within a species or population. Many behaviors involve motor output—that is, muscle movements—while others involve less visible actions, such as learning.

01:29The Influence of Affect on Cognition
281
Positive affect significantly influences cognitive processes, including evaluation, memory, creativity, and social judgments. Compared to negative affect, positive emotional states promote more favorable interpretations of stimuli, cognitive flexibility, and heuristic processing. These effects highlight emotions' powerful role in shaping how individuals perceive, remember, and interact with the world.Influence on Evaluation and AttributionWhen individuals experience positive affect, they are...
