Although some research has suggested that very young children are "immune" to functional fixedness (FF), other work has shown that young children form robust associations between objects and their prescribed functions. Across two studies, I investigated (a) the developmental trajectory of FF and (b) its relationship with executive function components (inhibitory control and working memory) in 3- to 6-year old children. Both older and younger children experience FF, but older children use familiar tools more flexibly than younger children (3- and 4-year olds). Furthermore, inhibitory control was related to overcoming FF, indicating that it may be an important cognitive capacity for creative problem-solving. Finally, in a third study, children were instructed to use mental imagery to help them solve the functional fixedness problems. However, these instructions were ineffective at reducing FF compared to a control condition, underscoring the robust nature of object-function relationships in early childhood.

Problem solving and strategy adaptation was assessed in 47 children ranging from 36 to 67 months. This was evaluated through problem sets in which participants were given tools that failed to reach given goal states, and then instructed to select appropriate tools in order to reach desired results. Analyses revealed that when participants were given a choice of tools to solve a given problem, they were more likely to select a correct tool when options were similar in function and appearance. Additionally, participants were more likely to verbalize the need for a new tool when there was a lack of novel tool choices. However, the presence of a novel tool choice was linked to longer problem solving time. Findings are congruent with literature that suggests children possess the ability to select tools based on functional, not superficial, qualities, and can be easily distracted by the presence of novel stimuli.

This qualitative study examined the nature of 5th-grade students' oral and written discourse in relation to their conceptual learning during six science inquiry-based lessons. Qualitative data were collected using small group observations, transcriptions of small group discourse, students' science notebooks, and student interviews. These data were used to create an in-depth illustration of 5th-grade students' discourse and the impact of that discourse on their science conceptual learning. Findings indicated students spoke in three main discourse classifications during small group inquiries and two of these discourses were also present in the science notebook entries. Findings further indicated gender did not impact the nature of students' oral or written discourse regarding their conceptual learning. Implications for classroom practice and suggestions for further research in elementary science education are offered.

The American Association of Colleges and Universities reports that over 50% of the students entering colleges and universities are academically under prepared; that is, according to Miller and Murray (2005), students "lack basic skills in at least one of the three fundamental areas of reading, writing, and mathematics". Furthermore, approximately 30% of the students in a state university undergraduate quantitative business course fail or withdraw from the course. The purpose of this study was to explore non-cognitive and cognitive factors that may be related to the academic success of those students enrolled in the course. To this end, a survey was conducted, collecting the perceptions and opinions of 301 undergraduate college of business students with regard to relevant constructs such as cognitive load, mathematics and general self-efficacy, math anxiety, and motivation. Additional data were collected from the students' transcripts. Findings revealed that the significant cognitive factors contributing to the academic success were the overall GPA of the students as well as the average of their grades in the two prerequisite courses. The statistically significant non-cognitive factors related to the final exam score were the students' perceived levels of cognitive load and mathematics self-efficacy. A moderating effect of mathematics self-efficacy was revealed between the final exam score and overall GPA; however, other selected potential moderators of the final exam score and cognitive load were not significant. Post-hoc analyses verified no significant difference in the final exam score for gender or race; however, a statistically significant difference was found on cognitive load for different instructors. The findings emphasized the importance of prior knowledge and instructional design as both are sensitive to cognitive load (Mayer & Moreno, 2003; Sweller, 1999).

Object use is a ubiquitous characteristic of the human species, and learning how objects function is a fundamental part of human development. This research examines the role that intentionality plays in children's understanding of causal relationships during imitation learning of object use. In Studies 1, 2, and 3, 2- to 5-year-olds observed demonstrations in which causally irrelevant and causally relevant actions were performed to achieve a desired goal of retrieving toys from within containers. Irrelevant actions were performed either intentionally ("There!") or accidentally ("Whoops! I didn't mean to do that!"). Study 1 found that 3-, 4-, and 5-year-olds, but not 2-year-olds, were less likely to imitate causally irrelevant actions performed accidentally than those performed intentionally. This suggests that older children used intentionality to guide causal inference, perceiving intentional actions as causally effective and accidental actions as causally ineffective. Study 2 foun d that the intentionality of the demonstrator's actions had an enduring effect - after watching a single demonstration, children persisted in performing intentional irrelevant actions and continued to ignore accidental irrelevant actions when given three successive opportunities to complete the task. Study 3 examined how lack of knowledge about the task goal prior to the demonstrations affected imitation and found that children without explicit verbal instruction of the toy-retrieval goal imitated irrelevant actions to a greater degree than children from Study 1, who were informed of the goal throughout the experiment. Study 4 progressed beyond irrelevant actions to investigate the effect of intentionality on 3- to 5-year-olds' imitation of relevant actions.

The purpose of this study was to investigate the self-directed learning (SDL) readiness of third-year medical students in comparison to previously reported scores for the general population; the relationship between SDL readiness and knowledge-based and performance-based measures of success in a medical school using an integrated medical curriculum; and to determine if knowledge-based and performance-based measures of success are significant in predicting Self-Directed Learning Readiness Survey/Learner Preference Assessment (SDLRS/LPA) and National Board of Medical Examiners Family Medicine Shelf Examination (NBME-FM) scores. This study analyzed SDLRS/LPA scores, knowledge-based scores (NBME-FM), performance-based scores (Objective Structured Clinical Examination [OSCE] and preceptor rating), and a combination of knowledge-based and performance-based scores (final grade). Analyses of 873 students resulted in mean scores of 229.06 + 23.19 for the SDLRS/LPA. Correlations were significant (p < .05) for SDLRS/LPA scores to NBME-FM scores (r = .073, p < .05). OSCE scores (r = .133, p < .01), and final grade (r = .138, p < .01). Regression analysis revealed that the total model of NBME-FM, OSC AVG, and preceptor rating predicted 2.1% of the variation in SDLRS/LPA, which was significant (p < .01). Regression analysis revealed that SDLRS/LPA, OSC AVG and preceptor ratings predicted 9.7% of the variance in NBME-FM, which was significant (p < .001). The results support previous findings that medical students' levels of SDL readiness are higher than the general population mean of 214.0 + 23.49.

This study tested the hypotheses that phonological memory contributes to vocabulary and grammatical development in young Spanish-English bilinguals, and that the relation between phonological memory and both vocabulary and grammar is language-specific. Phonological memory skill was the percentage of consonants correctly repeated (PCC) in English, and Spanish Nonword Repetition (NWR) tasks at 22 months. Vocabulary size and grammatical complexity were measured at 25 months using the English and Spanish versions for the MacArthur-Bates Communicative Development Inventories. Nonword repetition accuracy was significantly related to both subsequent vocabulary size and grammatical complexity within and across languages after controlling for the percentage of input in English. The relations were not significantly higher within than between languages. The results suggest that in these young Spanish-English simultaneous bilinguals phonological memory is a language-general ability that contributes to the development of vocabulary and grammar in both English and Spanish.

Linguistic research suggests that speakers represent syllable structure by a CV-frame. CVC syllables are more frequent than VCC ones. Further, the presence of VCC syllables in a language asymmetrically implies the presence of CVC syllables. These typological facts may reflect grammatical constraints. Alternatively, people's preferences may be due solely to their sensitivity to the statistical properties of sound combinations in their language. I demonstrate that participants in an auditory lexical decision task reject VCC nonwords faster than CVC nonwords, suggesting that the marked VCC syllables are dispreferred relative to CVC syllables. In a second experiment, I show that people are also sensitive to the distribution of these frames in the experiment. Findings indicate that syllable structure is represented at the phonological level, that individuals have preferences for certain syllables, and that these preferences can not be accounted for by the statistical properties of the stimuli.

Two and 3 year-old children's understanding of tool affordances was investigated by measuring their tool choice decisions and tool use behaviors. Children attempted six toy retrieval tasks of three different levels of structural complexity. Children were assigned to one of four conditions in which exposure to task materials varied according to the way in which the information was presented: no experience / no observation, experience only, observation only, and experience and observation. Three year- olds consistently made more correct choices and used more working tools successfully than 2-year-olds. Tool choice was affected primarily by task difficulty and age. Tool use was influenced by task difficulty, order of task difficulty, age, and condition. The observation condition was most beneficial to children, while experience was least helpful, particularly for tasks at the hard level of difficulty.

The purpose of this study was to explore the relationship between experiential learning and self-directed learning readiness of bachelor's and master's level social work students. A quantitative design was utilized. The study consisted of 115 senior social work students and 70 master's level social work students (separated into three student groups) from a state university. Students participated in a one-semester field education component as part of their social work degree program. The research instrument utilized was the Self-Directed Learning Readiness Scale (SDLRS) constructed by Guglielmino (1978). The SDLRS is a self-report questionnaire with 58 Likert scale items designed to measure the attitudes, values and abilities of learners relating to their readiness to engage in self-directed learning. A pretest, treatment, posttest design was utilized. Demographic data were collected with the pretest administration and level of satisfaction information was collected with the posttest administration. The bachelor's level social work students demonstrated statistically significant differences in the pre and posttest SDLRS scores while the master's level social work students' changes in readiness for self-directed learning were not significant. It is important to note that the master's level social work students spent only half the amount of hours in the field education as the bachelor's level students at the time of the posttest. Correlations between change score from pretest to posttest SDLRS with students' previous exposure to the field of social work, prior experiential learning in a social work program, their satisfaction with the experiential learning component, and demographic factors of gender, age, ethnicity, marital status, number of children, and number of years pursuing degree were not significant.
