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
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.
