Decoding visual category information from scalp EEG data with logistic regression and support vector machine classifiers

by

Abstract: The brain represents different categories of visual stimuli through distinct patterns of neural activity. Much of the evidence for this idea comes from functional magnetic resonance imaging (fMRI) in humans. However, fMRI is an indirect measure of neural activity that has low temporal resolution, limiting its ability to accurately capture the temporal dynamics of … Read more

Fidelity of Implementation in a Preschool Math Intervention

by

Abstract: Fidelity of implementation measures the extent to which teachers or other implementors follow the ideal of an intervention. It serves as a measure of internal validity, a check of experimental manipulation, and can allow researchers to attribute success or failures to the intervention. It is a crucial element of an educational intervention, but many studies do not even mention it. With the Wesleyan Preschool Math Games, a set of research-based math games … Read more

Perceived Social Support and Positive COVID-19 Experiences: A Case for Examining the Intersectionality of Gender and Sexuality among Emerging Adults

by

Abstract: Previous studies indicate that perceived social support is linked to better well-being (Kalaitzaki et al., 2020; Labrague et al., 2021). Indeed, during the pandemic, those with greater social support have been less negatively impacted by COVID-19 (Mai et al., 2021). However, emerging adults who identify as members of minority groups (e.g., LGBTQ+) may have … Read more

Our Sensory Experiences With Words Affect How We Read

by

Abstract: People process words faster when the meaning of the word has a clear physical or mental representation. Imageability ratings measure how easy a word is to visualize, while sensory experience ratings (SER) capture how well a word can be perceived through all senses. We collected SER and imageability ratings from Wesleyan undergraduates for 248 … Read more

Social Cognition in Schizophrenia: Does Culture Matter?

by

Abstract: Schizophrenia occurs in around 1% of the population worldwide and is diagnosed in all cultures and socioeconomic groups. Individuals with schizophrenia experience varying levels of social cognitive deficits in domains such as theory of mind, empathy, affect recognition, attributional style and social perception. These deficits may serve as barriers to normal social interactions and … Read more

Does grammatical morphology impact number word learning? A cross-linguistic analysis

by

Abstract: The mechanisms by which young children learn the exact meanings of number words are relatively unknown. Some linguists and child development experts believe that grammatical morphology drives early number word learning. To investigate this theory, Almoammer et al. (2013) researched number learning across populations with linguistic variation in how they grammatically denote quantity. The … Read more
