Summary
Mandarin-speaking English learners rated their peers' accents more harshly than native speakers, revealing bias. This study highlights accent stereotypes and their impact on language education.
Area of Science:
- Linguistics
- Sociolinguistics
- Second Language Acquisition
Background:
- Accent stereotyping is prevalent, even when speech is intelligible.
- Previous research on second language (L2) accent perception yields conflicting results, particularly among homogenous learner groups.
Purpose of the Study:
- To investigate whether Mandarin-speaking advanced English learners exhibit bias by rating L2 learner accents more critically than Standard American English (SAE) accents.
- To explore L2 listeners' beliefs regarding accented speech.
Main Methods:
- A survey was conducted to gauge L2 listeners' attitudes towards accented speech.
- Two experiments involved participants rating audio recordings of L2 learner speech and SAE speech.
- Experiment 2 utilized a detailed word-in-sentence accent rating task for more granular analysis.
Main Results:
- A significant level of perceived L2 accentedness was observed in learner speech, even when intelligibility was high.
- Strongly accented Cantonese passages and specific vowel/consonant errors were rated particularly harshly.
- Results indicate a bias against non-native accents among Mandarin-speaking English learners.
Conclusions:
- The study reveals the presence of 'native-speakerism' and accent stereotypes within the Chinese context.
- Findings have implications for language teaching methodologies and policy development concerning accent bias.

Stereotype Content Model
14.8K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Stereotypes, Prejudice, and Discrimination
90.3K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Stereotype Threat and Self-fulfilling Prophecies
37.7K
When we hold a stereotype about a person, we have expectations that he or she will fulfill that stereotype. A self-fulfilling prophecy is an expectation held by a person that alters his or her behavior in a way that tends to make it true. When we hold stereotypes about a person, we tend to treat the person according to our expectations. This treatment can influence the person to act according to our stereotypic expectations, thus confirming our stereotypic beliefs. Research by Rosenthal and...

The Representativeness Heuristic
15.8K
The representative heuristic describes a biased way of thinking, in which you unintentionally stereotype someone or something. For example, you may assume that your professors spend their free time reading books and engaging in intellectual conversation, because the idea of them spending their time playing volleyball or visiting an amusement park does not fit in with your stereotypes of professors.

Lateralization
375
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

Confirmation Biases
5.5K
The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?
