Description
Fast mapping is the initial link infants make between a word and its referent, and it is crucial to later processes of learning the meanings of words. Despite the importance of fast mapping, previous research has suggested that fast mapping is fragile, with infants being unable to retain words learned through fast mapping longer than five minutes. The current study tested the robustness of fast mapping by imposing task irrelevant interruptions on a fast mapping task. Forty-seven infants (14.7 \u2014 17.4 months old) were assigned to a No Interruption condition, a Posture Interruption condition, or a Visual Interruption condition, and they performed a fast mapping task in which a novel object was named in one trial. Videos of the infants were coded for accuracy of fast mapping and for attentional behaviors (looking behavior) during the task. We found that infants did not learn novel word-object pairings when interrupted, demonstrating that infants' fast mapping abilities are easily disrupted. Overall, there was no evidence that looking behaviors were affected by interruptions, or that they were correlated with accuracy. These findings suggest that fast mapping is fragile in young infants, and further research is required to determine the mechanisms for infant learning, and how infants transition from fast to slow mapping processes.

Description
For many years now, early word learning in children has been an important subject among many researchers. There are many ways in which children learn word-object pairings including using co-occurrences, forwards integration, and backwards integration. This study primarily focuses on backwards integration. Backwards integration entails using learned information to be able to recall a word-object pairing from a previous time. In this thesis, three different studies were conducted with children aged 3-7 years old. In the general task, children were presented with a computerized word-learning task in which they could track word-referent pairings using co-occurrence statistics, forward integration, and backward integration. The goal of Study 1 and Study 2 was to determine the best task design to study backwards integration. The goal of the final study, Study 3, was to provide preliminary data on backwards integration. The overall results indicate that a between subjects design is the most beneficial way to test backwards integration because as a group, children were learning when compared to chance. In addition, the results from Study 3 showed that children were not learning in the task. In general, this suggests that this task may have been very difficult for children to complete. One limitation of Study 3
was that there was a small sample size of only 29 children. In order to account for this, the sample sizes in Study 2 and Study 3 were combined. This combined data did show that children succeeded at the backwards integration condition. It is noteworthy to mention that backwards integration was above chance in Study 2 and in the Study 2 and 3 combination. Therefore, the overall results suggest that children may possibly be able to backwards integrate; however, no evidence of learning in any of the other conditions were present.

Description
The ability to regulate emotions, attention, and behavior develops early in life and impacts future academic success, social competency, behavioral problems, and psychopathology. An impairment in regulation is known as dysregulation. Past research shows that children of mothers with postpartum depression are more likely to show impairment in regulatory abilities. There is an established link in the literature between family support and maternal depression, which in turn can impact child behavior. However, further research is needed to explore the impact of family support on early childhood dysregulation in the context of maternal depression. Using a sample of 322 Mexican-American, mother-child dyads, two models were examined. Model one hypothesized family support would buffer the effects of maternal depression on child dysregulation at 24 months. Model 2 hypothesized that family support is related to child dysregulation through its effect on maternal depression. Results showed that increased family support was related to more child dysregulation when there were high levels of maternal depression. There was no evidence to support the hypothesis that maternal depression mediated the relationship between family support and child dysregulation.

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. 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.

Description
Environmental factors, including parents, play an important role in promoting children’s curiosity. Though curiosity is rooted in infancy, little is known about how parent-child interactions affect infants’ curiosity. The current study investigated the different ways parents promote curiosity through their infants’ exploration of a novel toy. We observed parent–child interactions between 39 parent-infant dyads in a semi-structured naturalistic 10-minute free play session. During the last 5 minutes of the session, parents were tasked with introducing a novel toy (i.e. a knotted foam curler) to the session, with no further instructions. Parent exploration-promoting and infant-exploratory behaviors during those 5 minutes were coded using a newly developed coding scheme, “Parental roles in Infant Curiosity through Exploration” (PICE). Findings revealed that when infants explored the novel toy, parents were more likely to observe rather than promote the exploration. However, when parents did promote the novel toy, infants were more likely to explore it if parents used explicit verbal cues. The study's focus on exploration-promoting verbal and nonverbal behaviors enables researchers to identify specific parenting behaviors that may have a significant impact on infant development and in turn, help develop interventions to support parents in fostering their children's curiosity and promoting early learning.

Description
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
The goal of this study was to examine whether there is any effect of phonotactic probability during the early phases of novel word recognition. In order to determine this, I performed two experiments. In Experiment 1, 33 adult monolingual English speakers learned 24 novel word-object pairings, half of which were high English phonotactic probability words and the other half were low English phonotactic probability words. I additionally included three conditions that varied the amount of exposures to each novel word-object pairing (i.e. One Exposure Condition, Two Exposures Conditions, and Five Exposures Condition). Experiment 2 was designed to clarify results found in Experiment 1, with improved randomization and fewer conditions (i.e. One Exposure Condition and Five Exposures Condition). The findings from both experiments were statistically significant in accuracy for Training condition, but not statistically significant for phonotactic probability nor for an interaction between phonotactic probability and Training condition. Although participants demonstrated learning across conditions there is no indication of a relationship between high and low phonotactic probability and novel word recognition. Collectively, these findings suggest that future studies will be necessary to determine if there is indeed an effect of phonotactic probability on early novel word recognition.

Description
Cross-situational word learning (CSWL) is a method of learning new words where an individual
is exposed to the word’s meaning in an ambiguous fashion throughout different contexts. Many
studies have been conducted using CSWL tasks on both children and adults. Most of these
studies look at single-label pairings, which is when one object is paired with one word. More
recently, research has also started to look at double-label pairings. Double-label pairings consist
of one object being paired with two words. No study to date has compared adult and children’s
performance in a double-label design. This study’s aim was to better understand how adults and
children compare in these tasks. The current study conducted two experiments to compare adult
and children’s performance in a CSWL task in either a single-label and double-label design.
Results showed that adults were successful in both conditions but performed better in the
single-label condition than the double-label condition. Children on the other hand were
unsuccessful in both conditions and did not demonstrate learning. Several reasons for these
findings are discussed. These results highlight the need for further research that directly
compares age groups in CSWL tasks and for further research into the area of multiple-label
pairings.

Description
Source monitoring refers to the ability to discriminate the origins of memories. The source monitoring framework is a theoretical model that describes the various characteristics of memories and judgement processes necessary for this discrimination process. Little research has analyzed the extent to which predictable encoding contexts influence source monitoring processes. In this study, we found that predictability at encoding aids later source recognition, but only when the test-relevant source dimension was predictable at encoding. The encoding format was either predictable (sequential spatial location) or non-predictable (random spatial location) and the test format was either color or location. In Experiment 1, the encoding format was either predictable or non-predictable spatial locations and participants were tested on the location. In this experiment, predictability did aid when the encoding format matched the test format. The average conditionalized source identification measure was statistically higher for those who saw images appear in a predictable pattern at encoding. In Experiment 2, when participants were tested on an orthogonal source dimension, the average conditionalized source identification measure was not statistically significant for those who saw the images appear in either encoding format. In this experiment, the predictability did not have an effect when the encoding format did not match the test format. In Experiment 3, there was a significant interaction of predictability by source dimension showing an improvement to memory for the predictable source condition and a decrement to memory for the unpredictable source dimension. In this experiment, predictability aided when encoding format matched the test format, but not when the encoding and test format did not match.

Description
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.
