Language and Cognition01:27

Language and Cognition

892
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.

Tip-of-the-Tongue Phenomenon01:10

Tip-of-the-Tongue Phenomenon

723
The tip-of-the-tongue (TOT) phenomenon is a cognitive experience characterized by a temporary inability to retrieve specific information from memory despite having a strong feeling of knowing the information. Although individuals cannot access the target word or detail, they frequently recall related elements, such as its initial letter, syllable count, or context. This partial retrieval often causes frustration, as one might recognize a familiar face or know that a name starts with a specific...

Synaptic Signaling01:09

Synaptic Signaling

5.7K
Neurons communicate at synapses, or junctions, to excite or inhibit the activity of other neurons or target cells, such as muscles. Synapses may be chemical or electrical.
Most synapses are chemical, meaning an electrical impulse or action potential spurs the release of chemical messengers called neurotransmitters. The neuron sending the signal is called the presynaptic neuron, and the neuron receiving the signal is the postsynaptic neuron.
The presynaptic neuron fires an action potential that...

Empathy02:34

Empathy

9.1K
Some researchers suggest that altruism operates on empathy. Empathy is the capacity to understand another person’s perspective, to feel what he or she feels. An empathetic person makes an emotional connection with others and feels compelled to help (Batson, 1991). Empathy can be expressed in several ways, including cognitive, affective, and motor.

Interference and Decay01:16

Interference and Decay

628
Forgetting is a complex cognitive phenomenon influenced by several factors, among which interference and decay are particularly prominent. These processes explain why individuals often struggle to retrieve specific information from memory, leading to lapses in recall that can be observed in everyday situations.
Interference occurs when competing memories hinder the retrieval of particular information. It can be classified into two types: proactive and retroactive interference. Proactive...

Area of Science:

  • Cognitive psychology
  • Psycholinguistics
  • Network science

Background:

  • Previous network analyses revealed the phonological lexicon has a web-like structure.
  • This structure exhibits assortative mixing by degree, linking words with similar phonological neighborhood densities.

Purpose of the Study:

  • To investigate if this network characteristic influences human lexical processing.
  • To examine evidence of assortative mixing in real and simulated lexical retrieval failures.

Main Methods:

  • Analysis of a slips-of-the-ear corpus.
  • Computer simulations of lexical retrieval.
  • Three psycholinguistic experiments.

Main Results:

  • Findings support the hypothesis that mental lexicon structure impacts word processing.
  • Evidence found for assortative mixing by degree in human lexical behavior.

Conclusions:

  • The structure of the mental lexicon plays a significant role in spoken word recognition and language processing.
  • Network science offers valuable insights into cognitive psychology models.
