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.

For this master's thesis, a unique set of cognitive prompts, designed to be delivered through a teachable robotic agent, were developed for students using Tangible Activities for Geometry (TAG), a tangible learning environment developed at Arizona State University. The purpose of these prompts is to enhance the affordances of the tangible learning environment and help researchers to better understand how we can design tangible learning environments to best support student learning. Specifically, the prompts explicitly encourage users to make use of their physical environment by asking students to perform a number of gestures and behaviors while prompting students about domain-specific knowledge. To test the effectiveness of these prompts that combine elements of cognition and physical movements, the performance and behavior of students who encounter these prompts while using TAG will be compared against the performance and behavior of students who encounter a more traditional set of cognitive prompts that would typically be used within a virtual learning environment. Following this study, data was analyzed using a novel modeling and analysis tool that combines enhanced log annotation using video and user model generation functionalities to highlight trends amongst students.

The purpose of this study was to investigate the effect of partial exemplar experience on category formation and use. Participants had either complete or limited access to the three dimensions that defined categories by dimensions within different modalities. The concept of "crucial dimension" was introduced and the role it plays in category definition was explained. It was hypothesized that the effects of partial experience are not explained by a shifting of attention between dimensions (Taylor & Ross, 2009) but rather by an increased reliance on prototypical values used to fill in missing information during incomplete experiences. Results indicated that participants (1) do not fill in missing information with prototypical values, (2) integrate information less efficiently between different modalities than within a single modality, and (3) have difficulty learning only when partial experience prevents access to diagnostic information.

Do good readers embody more or less? The current investigation examined embodiment effects as a function of individual reading skill in the context of two cognitive theories of reading comprehension. The Construction-Integration model predicts that sensorimotor activity during reading will correlate negatively with reading skill, because good readers focus on relations among abstract ideas derived from the text. Supposedly those abstract ideas have little or no sensorimotor content, hence any sensorimotor activity while reading is wasted effort. In contrast, the simulation theory predicts that sensorimotor activity will correlate positively with reading skill, because good readers create a simulation of what is happening within the text to comprehend it. The simulation is based in neural and bodily systems of action, perception, and emotion. These opposing predictions were tested using the reading-by-rotation paradigm to measure embodiment effects. Those effects were then correlated with reading skill measured using the Gates-McGinite standardized reading test. Analyses revealed an unexpected interaction between condition and congruency, and a negative relationship between embodiment and reading skill. Several caveats to the results are discussed.

Brain-computer interface technology establishes communication between the brain and a computer, allowing users to control devices, machines, or virtual objects using their thoughts. This study investigates optimal conditions to facilitate learning to operate this interface. It compares two biofeedback methods, which dictate the relationship between brain activity and the movement of a virtual ball in a target-hitting task. Preliminary results indicate that a method in which the position of the virtual object directly relates to the amplitude of brain signals is most conducive to success. In addition, this research explores learning in the context of neural signals during training with a BCI task. Specifically, it investigates whether subjects can adapt to parameters of the interface without guidance. This experiment prompts subjects to modulate brain signals spectrally, spatially, and temporally, as well differentially to discriminate between two different targets. However, subjects are not given knowledge regarding these desired changes, nor are they given instruction on how to move the virtual ball. Preliminary analysis of signal trends suggests that some successful participants are able to adapt brain wave activity in certain pre-specified locations and frequency bands over time in order to achieve control. Future studies will further explore these phenomena, and future BCI projects will be advised by these methods, which will give insight into the creation of more intuitive and reliable BCI technology.

Language comprehension is an essential skill in many aspects of life, yet some children still struggle with oral comprehension. This study examined the effectiveness of an intervention to improve the listening skills and comprehension of 4 and 5-year olds. This intervention is based on principles of embodied cognition, namely that language comprehension requires a simulation (or imagination) of what the language is about. Thus, children in the intervention condition moved pictures on an iPad to simulate the stories they were hearing. Children in the control condition saw the pictures, but did not move them. To identify the effectiveness of this simulation training, we analyzed scores on a comprehension test, and changes in motor cortex activity while listening. If the intervention increases simulation, then compared to the control, a) children given the intervention should perform better on the comprehension test, and b) those children should show greater activity in their motor cortices while listening. Furthermore, the change in motor cortex activity should statistically mediate the change in comprehension. Our results showed a significant positive correlation (.79) in the EMBRACE group (but not in the control) between the change in mu suppression before and after the intervention and the change in comprehension questions before and after the intervention. This correlation suggests that children can be taught to use their motor cortices while listening, and supports our hypothesis that embodied language theories, such as simulation are useful for enhancing comprehension.

Estradiol (E2) and Levonorgestrel (Levo) are two hormones commonly used in hormone therapy (HT) to decrease symptoms associated with menopause. Both of these hormones have been shown to have beneficial effects on cognition when given alone in a rodent model of menopause. However, it is unknown whether these hormones, when taken in combination, are beneficial or harmful to cognition. This is a critically important question given that these hormones are most often given in combination versus separately. This thesis is composed of two studies examining the cognitive effects of E2 and Levo using a rat model of surgical menopause. Study 1 assessed how the dose of E2 treatment in rats impacted cognitive performance, and found that low dose E2 enhanced working memory performance. Next, based on the results from Study 1, Study 2 used low dose E2 in combination with different doses of Levo to examine the cognitive effects of several E2 to Levo ratio combinations. The results from Study 2 demonstrated that the combination of low dose E2 with a high dose of Levo at a 1:2 ratio impaired cognition, and that the ratio currently used in HT, 3:1, may also negatively impact cognition. Indeed, there was a dose response effect indicating that working and reference memory performance was incrementally impaired as Levo dose increased. The findings in this thesis suggest that the E2 plus Levo combination is likely not neutral for cognitive function, and prompts further evaluation in menopausal women, as well as drug discovery research to optimize HT using highly controlled preclinical models.

The purpose of the Preschool Intervention for Embodied Storytelling (PIES) study was to evaluate the efficacy of a drama-based story time intervention on at-risk preschool students’ emotion knowledge, story retell and story comprehension skills. Six classrooms with 44 students were randomly assigned into drama-based intervention and dialogic reading control groups. After four weeks of intervention sessions twice per week, students’ emotion knowledge and story retell skills were assessed with distal measures. During the program, students’ comprehension of the stories was evaluated weekly. Participants did not show significant main effects on any measures, however investigation of simple effects revealed differences in gains over time for intervention students in their story retell skills. Despite lack of significance, effect sizes for story retell were promising. Mean differences in story comprehension skills were consistently in favor of the intervention group for the duration of the program. Teacher participants showed an increase in their positive perceptions of drama-based instruction, but their own use of these strategies at story time was variable before and after observing the PIES program. Drama based instruction through PIES may be a favorable intervention strategy for preschool students as they develop narrative skills that are a prerequisite for future reading comprehension success.
