Password cracking based on dictionary attacks have been confined only to the use of dictionary strings which make sense to both humans and the computer or are usually alphanumeric keyboard patterns. But here we also try to extend the dictionary attacks to homophones which the millennials tend to use more often. The word LOVE is used as LUV, LAV. Based on the pronunciation of a word there can be many spellings to it. Phoneme to Grapheme Correspondences have a great amount of significance here. So here in this research we try to incorporate all such words in the attacking dictionary with the highest possible probabilities to see if it has any impact on the password cracking efficiency. We use the probabilistic context-free grammar password cracker to see what our test results yield.

Text comprehension in adults is correlated with a number of other abilities including working memory span, inference making, and reading experience. There are fewer studies reporting correlations between lexical and sublexical skill and comprehension skill in adults. Comprehension skill in adults may constitute (1) a basic comprehension skill, like lexical skill, that drives the ability to construct representations of text and analyze them; (2) a more sensitive measure of lexical skill, for which it is difficult to measure sufficient variability in competent readers; or (3) a learned skill, derived from an individual’s reading experience. Reading a greater quantity and more varied texts increases the size of the knowledge base, the efficiency with which information can be accessed, the likelihood that effective reading strategies will be developed, and with these the enjoyment of reading and the desire to read more. These possibilities are explored in this experiment.We developed sensitive tests of lexical skill and measured comprehension skill and lexical skill using multiple tests in a large number of college students. In order to determine the effect of lexical skill on comprehension skill we divided participants into groups based on both variables in a two by two design. Using an artificial orthography allowed us to control reading experience.Patterns of responses to homophones and nonhomophones and to high and low frequency words indicate that differences in lexical skill affect not only the extent and time course of lexical activation but also the direction of the effect. There is some evidence for an interaction with comprehension ability.Lexical skill affected speed of learning and degree of learning success. Comprehension skill affected the ability to use the artificial orthography in other tasks, including ERP tasks. Effects were not mediated by working memory, inferencing, or lexical skill, suggesting the influence of a basic comprehension skill and an ability to assess the needs of new tasks and adapt their performance appropriately. Both lexical and comprehension skill affected performance on tasks in English, suggesting an influence of reading experience.

語言系統中，形音之間的映照關係為一持續受到探討的議題。本篇論文旨在利用眼動閱讀實驗以及口語理解─視覺典範深入探究閱聽中文形聲字時，音形映照之存在性及其時序歷程。 本文進行兩個眼動實驗。實驗一旨在探究視覺的閱讀歷程中，中文的音形映照於詞彙層次和次詞彙層次之歷程及影響。結果顯示，同音字密度效果未達顯著，但音形對應一致性效果於晚期眼動指標中顯著呈現。顯示出音形映照於視覺詞彙辨識的晚期產生影響，並證實語音表徵和字形表徵於視覺處理中是互為雙向影響之觀點，實驗一結果並支持音至形的反向連結映照於視覺模式中具有其重要性。實驗二主要使用口語理解─視覺典範，進一步探究並檢驗音形映照於口語詞彙辨識過程中之時序及歷程。結果顯示，音形對應一致性效果於早期眼動指標中顯著呈現，隨後同音字密度效果於晚期眼動指標中顯著呈現。此研究結果支持雙向交互激發模型(BIAM)之假設，顯示詞彙辨識機制中，存在字音和字形表徵之間的動態交互連結；並證實字形表徵於口語詞彙辨識過程中時序性的影響。 整體而論，本研究整合形音映照之概念所衍生出的形音一致性效果及同音字密度效果，就視、聽兩種模式之眼動實驗，檢視音形映照歷程，並進一步提供音形映照的實驗證據，探究其於中文語言系統的文字辨識歷程中之影響力與重要性。 / The present study aims to examine the states of phonological to orthographic (P-O) mappings when reading and listening Chinese phonograms. Two eye tracking experiments regarding to visual and auditory modalities were conducted to explore the intrinsic nature and the temporal dynamics of P-O mappings in Chinese word recognition. Experiment 1 manipulated homophone density and P-O consistency to investigate the involvement of P-O mappings at lexical and sublexical levels during the reading process. The result of Experiment 1 revealed that the P-O consistency effect was evident in second-pass eye movement indices of total viewing time (TVT) and rereading rate (RRR), demonstrating a late occurrence of P-O consistency effect at a the verification stage in reading. The occurrence of P-O consistency is in accordance with the view that the phonological information and orthographic representation are activated in a bidirectional flow, which implies that the mappings from phonology to orthography were guaranteed during the reading process. Experiment 2 utilizes visual world paradigm to explore the P-O mappings in auditory modality and further inspect the temporal dynamic in listening Chinese spoken characters. The result demonstrated that the P-O consistency effect emerged approximately 300 ms earlier than the homophone density effect, reflecting the early P-O consistency effect and the relatively late HD effect during the temporal stage of spoken word recognition. The result also supports the bidirectional activation of orthographic and phonological codes during word recognition, demonstrating the notion that the dynamic influences of orthography representation on spoken word recognition are ubiquitous at both sub-lexical and lexical levels.
