Extending the Wham-Womb Effect: Mapping Vowel Phonemes onto the Emotional Dimension of Arousal Using Cartoon Illustrations

Description

Recent studies indicate that words containing /ӕ/ and /u/ vowel phonemes can be mapped onto the emotional dimension of arousal. Specifically, the wham-womb effect describes the inclination to associate words with /ӕ/ vowel-sounds (as in “wham”) with high-arousal emotions and words with /u/ vowel-sounds (as in “womb”) with low-arousal emotions.…

Recent studies indicate that words containing /ӕ/ and /u/ vowel phonemes can be mapped onto the emotional dimension of arousal. Specifically, the wham-womb effect describes the inclination to associate words with /ӕ/ vowel-sounds (as in “wham”) with high-arousal emotions and words with /u/ vowel-sounds (as in “womb”) with low-arousal emotions. The objective of this study was to replicate the wham-womb effect using nonsense pseudowords and to test if findings extend with use of a novel methodology that includes verbal auditory and visual pictorial stimuli, which can eventually be used to test young children. We collected data from 99 undergraduate participants through an online survey. Participants heard pre-recorded pairs of monosyllabic pseudowords containing /ӕ/ or /u/ vowel phonemes and then matched individual pseudowords to illustrations portraying high or low arousal emotions. Two t-tests were conducted to analyze the size of the wham-womb effect across pseudowords and across participants, specifically the likelihood that /ӕ/ sounds are paired with high arousal images and /u/ sounds with low arousal images. Our findings robustly confirmed the wham-womb effect. Participants paired /ӕ/ words with high arousal emotion pictures and /u/ words with low arousal ones at a 73.2% rate with a large effect size. The wham-womb effect supports the idea that verbal acoustic signals tend to be tied to embodied facial musculature that is related to human emotions, which supports the adaptive value of sound symbolism in language evolution and development.

Replicating the Gleam-Glum Effect: Basic Phonemes Associated with Emotional Valence When Pairing Nonsense Syllables with Pictures

Neuroscientific research has verified that humans have specialized brain areas used in the production and perception of language. It is speculated that these brain areas may also be involved in the perception and expression of emotions. A recent study supports the idea of an auditory equivalent to visually recognizable emotions, finding that the words containing the phoneme /i:/ as in “beat” were rated more positively and those with the phoneme /^/ as in “but” were rated more negatively. It was theorized that these results support that the same facial musculature used in producing visually recognizable expressions also favors specific phonemic sounds. The present study replicates this prior research using a new methodology in which participants matched verbalized monosyllabic nonsense pseudo-words to positive or negative cartoon pictures. We hypothesized that pseudo-words containing the sounds /i:/ would be matched with pictures that are more emotionally positive and ones containing the sounds /^/ would be matched with pictures that are more negative. Data collected from 119 undergraduate student volunteers from a Southwestern public university confirmed our hypotheses and exhibit the same pattern found in previous research supporting that specific vowel phonemes are matched with emotional valence. Our findings are the first to confirm this phoneme-emotion relationship with verbalized sounds and pictures. The results support the idea that the musculature associated with positive and negative facial expressions also favors production of specific phonemic sounds that listeners recognize and associate with specific emotions.
