Summary
Spoken word recognition models may be sensitive to talker-specific information. Repeated exposure to words from the same talker can influence lexical competition, impacting how we process speech.
Area of Science:
- Psycholinguistics
- Cognitive Science
- Speech Processing
Background:
- Models of spoken word recognition often assume lexical competition is talker-invariant.
- Investigating talker-specific information is crucial for understanding the nuances of speech perception.
Purpose of the Study:
- To determine if the lexical competition process in spoken word recognition is sensitive to talker-specific information.
- To explore the role of talker repetition in modulating competition effects.
Main Methods:
- A lexical decision task was employed with a long lag priming experiment.
- Stimuli involved phonemically similar primes and targets (e.g., /bagaR/ vs. /bagaƷ/).
- Two experiments varied the presentation frequency of competitor prime blocks and examined talker changes between primes and targets.
Main Results:
- Experiment 1 showed no modulation of competitor priming with a single presentation of the prime block, regardless of talker change.
- Experiment 2 revealed an attenuation of the competitor priming effect when a talker change occurred after five presentations of the prime block.
- This suggests that repeated exposure to a talker influences lexical competition.
Conclusions:
- Findings support hybrid models of spoken word recognition that incorporate talker-dependent representations.
- Repetition of words by the same talker may be a key factor in forming and accessing these talker-specific representations.
- Talker-specific information plays a significant role in spoken word recognition.

First impressions play a crucial role in social perception, shaping how individuals assess others in professional, academic, and interpersonal contexts. Psychological research highlights the significance of cognitive biases, such as the primacy and recency effects, which influence how people interpret and recall information.The Primacy Effect and Cognitive AnchoringThe primacy effect describes the tendency for initial information to impact judgment disproportionately. When individuals encounter...

01:27Language and Cognition
912
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.

591
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...

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

01:03Serial Position Effect
621
The serial position effect is a cognitive phenomenon where individuals are more likely to recall the first and last items in a list compared to those in the middle. This effect is divided into the primacy effect and the recency effect. The primacy effect is observed when the initial items in a list are remembered better. This occurs because these items are rehearsed more frequently or receive more elaborative processing, allowing them to be encoded into long-term memory more effectively. For...
