Summary
Extensive practice on a global-local task eliminated global processing advantages. Training reduced global interference but increased local interference, impacting stimulus and task processing.
Area of Science:
- Cognitive Psychology
- Perceptual Learning
Background:
- Global/local processing involves attending to overall shapes or individual components.
- Understanding how practice affects these processing biases is crucial for cognitive models.
Purpose of the Study:
- To investigate interference, inhibition, and transfer effects from training on a global-local task.
- To examine how extensive practice alters global processing advantages and interference patterns.
Main Methods:
- Participants completed 10,080 training trials focused on identifying local features within global/local stimuli.
- Interference and transfer effects were analyzed post-training.
Main Results:
- Practice eliminated the typical global processing advantage.
- Global interference decreased, while local interference increased with training.
- Transfer effects were stimulus-specific for local processing and task-specific for global processing.
Conclusions:
- Training significantly modulates global-local processing dynamics.
- Findings provide insights into adaptive changes in perceptual learning and cognitive control.

01:27Language and Cognition
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.
01:25Long-term Potentiation
Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTP is the process of synaptic strengthening that occurs over time between pre and postsynaptic neuronal connections. The synaptic strengthening of LTP works in opposition to the synaptic weakening of long-term depression (LTD) and together are the main mechanisms that underlie learning and memory.

01:20Parallel Processing
The brain processes sensory information rapidly due to parallel processing, which involves sending data across multiple neural pathways at the same time. This method allows the brain to manage various sensory qualities, such as shapes, colors, movements, and locations, all concurrently. For instance, when observing a forest landscape, the brain simultaneously processes the movement of leaves, the shapes of trees, the depth between them, and the various shades of green. This enables a quick and...
