Dr. E. Paul Torrance, "Father of Creativity," is best known for developing the Torrance Tests of Creative Thinking (TTCT). The TTCT was developed by Torrance in 1966. It has been renormed 4 times: in 1974 (Millar, 2002). It has become highly recommended in the educational field and is even used in the corporate world. It is the most widely used test of creativity (Davis, 1997) and is the most referenced of all creativity tests (Lissitz & Willhoft, 1985). Basic information is presented, including purposes, content area, norms, reliability, and validity. Strengths and weaknesses of the TTCT, including use of the TTCT in identifying gifted learners and suggestions for further development and improvement, are provided and discussed. . There are 2 forms (A and B) of the TTCT-Verbal and 2 forms (A and B) of the TTCT-Figural. However, in the scope of this review, only the TTCT-Figural was examined. The TTCT has been translated into more than 35 languages

uilford (1962) hypothesized that creative individuals possess divergent thinking abilities that traditional IQ tests do not measure, and other researchers have shown that creativity test scores, divergent thinking tasks, and creative achievement are independent

It has frequently been reported that exposure to artificial light at night (ALAN) may cause negative health effects, such as breast cancer, circadian phase disruption and sleep disorders. Here, we reviewed the literature assessing the effects of human exposure to ALAN in order to list the health effects of various aspects of ALAN. Several electronic databases were searched for articles, published through August 2014, related to assessing the effects of exposure to ALAN on human health; these also included the details of experiments on such exposure. A total of 85 articles were included in the review. Several observational studies showed that outdoor ALAN levels are a risk factor for breast cancer and reported that indoor light intensity and individual lighting habits were relevant to this risk. Exposure to artificial bright light during the nighttime suppresses melatonin secretion, increases sleep onset latency (SOL) and increases alertness. Circadian misalignment caused by chronic ALAN exposure may have negative effects on the psychological, cardiovascular and/or metabolic functions. ALAN also causes circadian phase disruption, which increases with longer duration of exposure and with exposure later in the evening. It has also been reported that shorter wavelengths of light preferentially disturb melatonin secretion and cause circadian phase shifts, even if the light is not bright. This literature review may be helpful to understand the health effects of ALAN exposure and suggests that it is necessary to consider various characteristics of artificial light, beyond mere intensity.

There is disagreement among researchers about whether IQ tests or divergent thinking (DT) tests are better predictors of creative achievement. Resolving this dispute is complicated by the fact that some research has shown a relationship between IQ and DT test scores (e.g., Runco & Albert, 1986;Wallach, 1970). The present study conducted meta-analyses of the relationships between creative achievement and both IQ and DT test scores. The analyses included 17 studies (with 5,544 participants) that established the correlation coefficients between IQ and creative achievement and 27 studies (with 47,197 participants) that established the correlation coefficients between DT test scores and creative achievement. Marginal, but statistically significant, Fisher's Z-transformed correlation coefficients were revealed. The analysis found a significantly higher relationship between DT test scores and creative achievement (r = .216) than between IQ test scores and creative achievement (r = .167). The differences in the correlation coefficients were explained by differences in DT tests, creative achievement types, predicted time periods, and creativity subscales. The significant independent moderator effect for different DT tests indicates that the Torrance Tests of Creative Thinking (TTCT) predict creative achievement better than any other DT test included in this study. Among the creative achievement types, music is predicted the best by IQ and all others are predicted best by DT tests. Among the time periods evaluated, the relationship between DT test scores and creative achievement had the highest correlation at the period of 11-15 years.

The B-type Raf kinase (BRAF) protein is a serine/threonine kinase that has an important role in cellular proliferation, differentiation, and programmed cell death. The BRAF gene has been recently found to be mutated in human carcinomas, predominantly in malignant melanoma. The aim of this study was to investigate the frequency of the BRAF mutation in papillary thyroid carcinoma (PTC) of Koreans through direct DNA sequencing of the polymerase chain reaction (PCR)- amplified exon 15 with clinicopathological features. Seventy paraffin-embedded conventional papillary carcinomas in the thyroid gland were evaluated. The BRAF missense mutation at V599E was found in 58 of 70 PTCs (83%). The frequency of our series was much higher than the frequencies of other PTC series (36 - 69%). The frequency of nodal metastasis was also significantly higher in the BRAF mutation group (p= 0.048). These results suggest that the BRAF mutation is involved in the carcinogenesis in most conventional PTCs, especially those occurring in Koreans, and this is a potentially valuable marker for the evaluation of prognosis of patients with PTC. These findings support the specific inhibitors of BRAF being promising targets for the disease outcome.

Autophagy is a dynamic cellular pathway involved in the turnover of proteins, protein complexes, and organelles through lysosomal degradation. The integrity of postmitotic neurons is heavily dependent on high basal autophagy compared to non-neuronal cells as misfolded proteins and damaged organelles cannot be diluted through cell division. Moreover, neurons contain the specialized structures for intercellular communication, such as axons, dendrites and synapses, which require the reciprocal transport of proteins, organelles and autophagosomes over significant distances from the soma. Defects in autophagy affect the intercellular communication and subsequently, contributing to neurodegeneration. The presence of abnormal autophagic activity is frequently observed in selective neuronal populations afflicted in common neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, Huntington's disease and amyotrophic lateral sclerosis. These observations have provoked controversy regarding whether the increase in autophagosomes observed in the degenerating neurons play a protective role or instead contribute to pathogenic neuronal cell death. It is still unknown what factors may determine whether active autophagy is beneficial or pathogenic during neurodegeneration. In this review, we consider both the normal and pathophysiological roles of neuronal autophagy and its potential therapeutic implications for common neurodegenerative diseases.
