Description
ABSTRACT This thesis proposes that a focus on the bodily level of analysis can unify explanation of behavior in cognitive, social, and cultural psychology. To examine this unifying proposal, a sensorimotor mechanism with reliable explanatory power in cognitive and social psychology was used to predict a novel pattern of behavior in cultural context, and these predictions were examined in three experiments. Specifically, the finding that people judge objects that require more motor effort to interact with as farther in visual space was adapted to predict that people with interdependent self-construal(SC) , relative to those with independent SC, would visually perceive their cultural outgroups as farther relative to their cultural in-groups. Justifying this cultural extension of what is primarily a cognitive mechanism is the assumption that, unlike independents, Interdependents interact almost exclusively with in-group members, and hence there sensorimotor system is less tuned to cross-cultural interactions. Thus, interdependents, more so than independents, expect looming cross-cultural interactions to be effortful, which may inflate their judgment of distance to the out-groups. Two experiments confirmed these predictions: a) interdependent Americans, compared to independent Americans, perceived American confederates (in-group) as visually closer; b) interdependent Arabs, compared to independent Arabs, perceived Arab confederates (in-group) as closer; and c) interdependent Americans, relative to independent Americans, perceived Arab confederates (out-group) as farther. A third study directly established the proposed relation between motor effort and distance to human targets: American men perceived other American men as closer after an easy interaction than after a more difficult interaction. Together, these results demonstrate that one and the same sensorimotor mechanism can explain/predict homologous behavioral patterns across the subdisciplines of psychology.

I recently established the gleam-glum effect confirming in both English and Mandarin that words with the /i/ vowel-sound (like “gleam”) are rated more emotionally positive than matched words with the /ʌ/ vowel-sound (like “glum”). Here I confirm that these vowel sounds also influence the semantic perception of monosyllabic pseudo-words. In Experiment 1, 100 participants rated 50 individual /i/ monosyllabic pseudo-words (like “zeech”) as significantly more positive than 50 matched /ʌ/ pseudo-words (like “zuch”), replicating my previous findings with real words. Experiment 2 assessed the gleam-glum effect on pseudo-words using a forced-choice task. Participants (n = 148) were presented with the 50 pairs of pseudo-words used in Experiment 1 and tasked to guess the most likely meaning of each pseudo-word by matching them with one of two meaning words that were either extremely positive or extremely negative in affective valence (Warriner et al., 2013). I found a remarkably robust effect in which every one of the 50 pseudo-word pairs was on average more likely to have the /i/ word matched with the positive meaning word and /ʌ/ word with the negative one (exact binomial test, p < .001, z = 7.94). The findings confirm that the gleam-glum effect facilitates bootstrapping meaning of words from their pronunciations. These findings coupled with previous real word findings (Yu et al., in press), showing not only that the effect encompasses the entire English lexicon but can also be explained with an embodied facial musculature mechanism, is consistent with the idea that sound symbolism may shape vocabulary use of a language over time by influencing semantic perception.

Description
Fractal analyses examine variability in a time series to look for temporal structure
or pattern that reveals the underlying processes of a complex system. Although fractal
property has been found in many signals in biological systems, how it relates to
behavioral performance and what it implies about the complex system under scrutiny are
still open questions. In this series of experiments, fractal property, movement kinematics,
and behavioral performance were measured on participants performing a reciprocal
tapping task. In Experiment 1, the results indicated that the alpha value from detrended
fluctuation analysis (DFA) reflected deteriorating performance when visual feedback
delay was introduced into the reciprocal tapping task. This finding suggests that this
fractal index is sensitive to performance level in a movement task. In Experiment 2, the
sensitivity of DFA alpha to the coupling strength between sub-processes within a system
was examined by manipulation of task space visibility. The results showed that DFA
alpha was not influenced by disruption of subsystems coupling strength. In Experiment 3,
the sensitivity of DFA alpha to the level of adaptivity in a system under constraints was
examined. Manipulation of the level of adaptivity was not successful, leading to
inconclusive results to this question.
