The Wham-Womb Sound Symbolic Effect: English-Speaking Children and Adults Link Phonemes with Arousal
Description
Sound symbolism—the association between word sounds and meaning—has been shown to be an effective communication tool that promotes language comprehension and word learning. Much of the literature is constrained to investigating sound as it relates to physical characteristics (e.g. size or shape), and research has predominantly studied the phenomenon in adults. The current study examined the sound symbolic wham-womb effect, which postulates that words with the /æ/ phoneme are associated with increased arousal while words with the /u/ phoneme are associated with little to no arousal. The effect was tested in both adults and children aged 5-7 years old using a word-to-scene matching task. Participants were presented with two pseudowords (differing only by their vowel phoneme: /æ/ or /u/; e.g. smad and smood) and two scenes depicting an animal in either a more arousing or less arousing situation. Participants were then asked to match which of the scenes fit one of the pseudowords. Results showed that the trial-by-trial performance for adults and children were significantly greater than chance, indicating that the wham-womb effect is exhibited in both adults and children. There was also a significant difference in performance between adults and children, with adults showing a more robust effect. This study provides the first empirical evidence that both children and adults link phonemes to arousal and that this effect may change across development.

Description
Categories are often defined by rules regarding their features. These rules may be intensely complex yet, despite the complexity of these rules, we are often able to learn them with sufficient practice. A possible explanation for how we arrive at consistent category judgments despite these difficulties would be that we may define these complex categories such as chairs, tables, or stairs by understanding the simpler rules defined by potential interactions with these objects. This concept, called grounding, allows for the learning and transfer of complex categorization rules if said rules are capable of being expressed in a more simple fashion by virtue of meaningful physical interactions. The present experiment tested this hypothesis by having participants engage in either a Rule Based (RB) or Information Integration (II) categorization task with instructions to engage with the stimuli in either a non-interactive or interactive fashion. If participants were capable of grounding the categories, which were defined in the II task with a complex visual rule, to a simpler interactive rule, then participants with interactive instructions should outperform participants with non-interactive instructions. Results indicated that physical interaction with stimuli had a marginally beneficial effect on category learning, but this effect seemed most prevalent in participants were engaged in an II task.

ABSTRACT
Learning a novel motor pattern through imitation of the skilled performance of an expert has been shown to result in better learning outcomes relative to observational or physical practice. The aim of the present project was to examine if the advantages of imitational practice could be further augmented through a supplementary technique derived from my previous research. This research has provided converging behavioral evidence that dyads engaged in joint action in a familiar task requiring spatial and temporal synchrony end up developing an extended overlap in their body representations, termed a joint body schema (JBS). The present research examined if inducing a JBS between a trainer and a novice trainee, prior to having the dyad engage in imitation practice on a novel motor pattern would enhance both of the training process and its outcomes.
Participants either worked with their trainer on a familiar joint task to develop the JBS (Joint condition) or performed a solo equivalent of the task while being watched by their trainer (Solo condition). Participants In both groups then engaged in blocks of alternating imitation practice and free production of a novel manual motor pattern, while their motor output was recorded. Analyses indicated that the Joint participants outperformed the Solo participants in the ability to synchronize the spatial and temporal components of their imitation movements with the trainer’s pattern-modeling movements. The same group showed superior performance when attempting to freely produce the pattern. These results carry significant theoretical and translational potentials for the fields of motor learning and rehabilitation.
