Neurotechnology has been applied to gain insights on creativity-related cognitive factors. Prior research has identified relations between cognitive factors and creativity qualitatively; while quantitative relations, such as the relative importance of cognitive factors and creativity, have not been fully determined. Therefore, taking the creative design process as an example, this study using electroencephalography (EEG) aims to objectively identify how creativity-related cognitive factors of retrieval, recall, association, and combination contribute to creativity. The theoretical basis for an EEG-based decoding method to objectively identify which cognitive factors occur in a creative process is developed. Thirty participants were recruited for a practical study to verify the reliability of the decoding method. Based on the methodology, relationships between the relative importance level of the cognitive factor and creative output quality levels were detected. Results indicated that the occurrence of recall and association are reported with a high reliability level by the decoding method. The results also indicated that association is the dominant cognitive factor for higher creative output quality levels. Recall is the dominant cognitive factor for lower creative output quality levels.

Researchers have taken great interest in the assessment of text readability. This study expands on this research by developing readability models that predict the processing effort involved during first language (L1) and second language (L2) text reading. Employing natural language processing tools, the study focused on assessing complex linguistic features of texts, and these features were used to explain the variance in processing effort, as evidenced by eye movement data for L1 or L2 readers of English that were extracted from an open eye-tracking corpus. Results indicated that regression models using the indices of complex linguistic features provided better performance in predicting processing effort for both L1 and L2 reading than the models using simple linguistic features (word and sentence length). Furthermore, many of the predictive variables were lexical features for both L1 and L2 reading, emphasizing the importance of decoding for fluent reading regardless of the language used.

Neuroprosthetic speech devices are an emerging technology that can offer the possibility of communication to those who are unable to speak. Patients with ‘locked in syndrome,’ aphasia, or other such pathologies can use covert speech—vividly imagining saying something without actual vocalization—to trigger neural controlled systems capable of synthesizing the speech they would have spoken, but for their impairment.

We provide an analysis of the mechanisms and outputs involved in speech mediated by neuroprosthetic devices. This analysis provides a framework for accounting for the ethical significance of accuracy, control, and pragmatic dimensions of prosthesis-mediated speech. We first examine what it means for the output of the device to be accurate, drawing a distinction between technical accuracy on the one hand and semantic accuracy on the other. These are conceptual notions of accuracy.

Both technical and semantic accuracy of the device will be necessary (but not yet sufficient) for the user to have sufficient control over the device. Sufficient control is an ethical consideration: we place high value on being able to express ourselves when we want and how we want. Sufficient control of a neural speech prosthesis requires that a speaker can reliably use their speech apparatus as they want to, and can expect their speech to authentically represent them. We draw a distinction between two relevant features which bear on the question of whether the user has sufficient control: voluntariness of the speech and the authenticity of the speech. These can come apart: the user might involuntarily produce an authentic output (perhaps revealing private thoughts) or might voluntarily produce an inauthentic output (e.g., when the output is not semantically accurate). Finally, we consider the role of the interlocutor in interpreting the content and purpose of the communication.

These three ethical dimensions raise philosophical questions about the nature of speech, the level of control required for communicative accuracy, and the nature of ‘accuracy’ with respect to both natural and prosthesis-mediated speech.

Decoding and language comprehension skills have been found to be the core components of reading comprehension across many writing systems. The present study examined the contributions of vocabulary and some discourse-level skills to reading comprehension in Chinese in addition to that of decoding. One hundred and seventeen Chinese second and third graders in Hong Kong were tested on decoding, vocabulary, discourse-level skills, and verbal working memory. Results of multiple regression analyses showed that the discourse-level skills contributed an additional 5% of variance to reading comprehension over decoding, vocabulary, and other control variables, and all factors accounted for a total of 70% variance in reading comprehension. Further path analysis showed that all the direct paths of word reading, vocabulary, text-structure knowledge, and topic knowledge to reading comprehension were significant. Vocabulary also contributed to reading comprehension through indirect paths to discourse-level knowledge. The present findings support the simple view of reading with elaborations on the language comprehension component, namely, (a) vocabulary is a foundational language skill for text comprehension through its role on discourse-level knowledge, and (b) some discourse-level knowledge also plays an important role in passage comprehension.

The aim of the paper is to investigate the role of dictionary form (paper versus electronic) in language reception, production and retention. The body of existing research does not give a clear answer as to which dictionary medium benefits users more. Divergent findings from many studies into the topic might stem from differences in research methodology (including the various tasks, participants and dictionaries used by different authors). Even a series of studies conducted by one researcher (Dziemianko, 2010, 2011, 2012b) leads to contradictory conclusions, possibly because of the use of paper and electronic versions of existing dictionaries, and the resulting problem with isolating dictionary form as a factor. To be able to argue with confidence that the results obtained follow from different dictionary formats, rather than presentation issues, research methodology should be improved. To successfully generalize about the significance of the medium for decoding, encoding and learning, the current study replicates previous research, but the presentation of lexicographic data on paper and on screen is now balanced, and the paper/electronic opposition is operationalized more appropriately. A real online dictionary and its paper-based counterpart composed of printouts of screen displays were used in the experiment in which the meaning of English nouns and phrases was explained, and collocations were completed with missing prepositions. A delayed post-test checked the retention of the meanings and collocations. The results indicate that dictionary medium does not play a statistically significant role in reception and production, but it considerably affects retention.

A key aspect of the work of many educational and developmental psychologists is the diagnosis of literacy learning disability. One component of this disability is learning to read words automatically. This difficulty is attributed to the gradual development of phonological decoding and the related acquisition of orthographic knowledge. Unfamiliar letter strings can be decoding either overtly, by saying aloud systematically parts of a written word and then blending the parts, or subvocally. Subvocal decoding is assumed to be more mature develapmentally and to be a key acquisition. The present study examines aspects of the acquisition of subvocal decoding by monitoring the reading of pseudowords by average and low achieving third to fifth graders. Subvocal phonological decoding ability was correlated with the accuracy, comprehension, and rate components of prose reading for both categories of reading ability and was higher for the average readers. Its accuracy was influenced by the number of letters in a pseudoword and its sound structure. Low achieving reoders showed a greater sensitivity to subvocal phonological decoding than average reoders. The implications for the diagnosis of reading disabilities by educational and developmental psychologists are discussed.
