Objective : The objective of this study was to determine a discriminat validity of the Sensory Processing Scale-Children (SPS-C) for children with and without Sensory Processing Disorder (SPD). Method : The SPS-C was completed by parents of 151 Korean children including 68 typically developing children (control group), 83 children with SPD (known group) in the age range 3-5 years, in South Korea. ANCOVA with sex as covariable was used to identified the difference between the children with typically development and SPD. Results : Sensory processing differences in sensory domains and sensory factors were detected and the gender differences were not effective between typically developing children and children with SPD. Significant differences were found in all sensory domain score and total score except proprioceptive processing in sensory domain. In sensory factors, significant differences were found in overrsensitivity, underresponsivity, and discrimination, but sensory seeking was not significant. SPS-C was a valid assessment tool to identify or screen of SPD in Korea. Conclusion : The psychometric characteristics for the standardization study of SPS-C were presented, and the discriminant validity to screen the children with sensory processing problems was presented as a verified evaluation tool. SPS-C will be helpful in screening, analyzing and interpreting characteristics of sensory processing, and establishing an intervention plan.

Sensory integration started as a theory to provide a occupational therapist with a useful frame for explaining and intervening the problems which children have. Most researches on sensory processing disorder (SPD) have been found empirical evidence to support the sensory integration theory by measuring behavioral manifestations of SPD. Recently, researchers who are interested in the diagnosis of SPD have begun to use neurophysiological methods to establish objective evidence for sensory integration. These studies reported the neurophysiological indexes reflecting the maladaptive behaviors as well as the difference between children with SPD and typically developing children in using electrodermal activity, vagal tone, EEG. Future neurophysiological studies on SPD will be expected to prove the efficacy of sensory integration intervention.

The purpose of this study was to investigate the relations between sensory processing and sleep disturbances and to investigate the effect of sensory processing on sleep disorder in preschool children with developmental disorder. This study was conducted for 110 children with developmental disorder in developmental clinic and rehabilitation hospital in Gwang Ju from June to August, 2017. The final 109 data were analyzed. Sensory processing and Sleep disturbances were measured using the Shortened sensory profile(SSP) and Korean-the Children's Sleep Habits Questionnaire(K-CSHQ). Statistical analysis was performed using descriptive analysis, Pearson correlation analysis, and multiple regression analysis were performed. Children with developmental disorder had problems with sensory processing and sleep habits. Sensory processing was related to sleep habit and most important factors of sensory processing influencing sleep was taste/olfactory sensitivity, auditory filtering. Conclusion: In order to help children with developmental disorder with sleep problem, it is necessary to consider the sensory processing especially taste/olfactory sensitivity, auditory filtering.

The purpose of this study was to examine the sensory processing of adults with intellectual disabilities by Adolescent/Adult Sensory Profile(AASP). AASP was executed for 98 adults with intellectual disabilities residing in nursing home. The score of sensory processing ability expressed the conditions of being 'Less Than Most People' and 'Much Less Than Most People' in the all sensory processing areas of Low Registration, Sensory Sensitivity, Sensory Seeking, Sensory Avoiding. There was not significant difference in the sex. The score of sensory processing ability between teenagers(11 years to 17 years) and adult(above 18 years), teenagers statistically showed lower scores in the three sensory processing areas of Low Registration, Sensory Seeking, and Sensory Sensitivity. In addition, there was significant difference in the sensory processing areas of Low Registration and Sensory Avoiding according to the disability grading. In the future research, it is suggested to examine the sensory processing within residual setting and it need a study comparing sensory processing skills according to the disability grading by increasing subjects.

Objective : The goal of this study was to investigate neurological mechanism of emotional regulation and to examine the relationship between the regulation and sensory processing. Subjective : Emotional regulations are mainly processed in limbic system, particularly the basal-lateral group of amygdala takes on a major role in the regulations. The basal-lateral group of amygdala links to thalamus directly and/or indirectly which processes sensory information together. This sensory information connects to orbital and medial prefrontal cortex. Inadequate sensory processing may cause difficulties in emotional regulations and behaviors because of a circuit linking the amygdala, the thalamus, and the orbital and medial prefrontal cortex. These difficulties and impairments has been reported in neurological studies for children with ASD and ADHD. Conclusion : Neurological states are different between the normal children and children with ASD and ADHD and these represent various aspects in sensory processing, emotional regulations and behaviors. Thus, therapists working with children with ASD and ADHD need to understand mechanisms of sensory processing and emotional regulations in order to provide adequate treatments.

Objective : This study aimed to identify the relationship between sensory processing and personality in college students by using five personality factors. Methods : The study was conducted between October and December 2022 with 149 college students majoring in health studies. Sensory processing was evaluated using the Adolescent/Adult Sensory Profile (AASP), and personality was evaluated using the International Personality Item Pool (IPIP). The data collected were analyzed by descriptive statistics, frequency analysis, and Pearson correlation analysis, and the Statistical Package for the Social Sciences (SPSS) was used. Results : Extraversion and agreeableness showed a significant correlation with all sensory processing types. Neuroticism showed a positive correlation with all types of sensory processing other than sensory seeking, while openness to experience showed a positive correlation with sensory seeking. Conscientiousness showed a negative correlation with low registration and sensory sensitivity type (p<.01). Conclusion : This study found a relationship between sensory processing type and personality type through an evaluation of five personality in college students. This information can be used to find solutions to various problems that college students.

Objective : The purpose of this study was to investigate the sensory processing factors that contribute to the temperament and character traits in early childhood. Methods : In this cross-sectional study, caregivers of typically developing children aged 3-6 years responded to the Sensory Profile and the Junior Temperament and Character Inventory. Multiple regression analysis was performed with temperament and character traits as criterion variables and sensory processing quadrants as predictive variables. Results : Sensory sensitivity significantly predicted novelty seeking and cooperativeness. The high frequency of sensory sensitivity behavior was related to high novelty seeking and low cooperativeness. Conclusion : This study demonstrated that sensory sensitivity contributes to the novelty seeking temperament and cooperativeness character in early childhood.

The purpose of this study was to compare the difference between the adaptive and internalizing/externalizing maladaptive behaviors of the sensory processing problemtic group classified from non-disabled preschoolers and to confirms the effects of sensory processing sub-factors on adaptive and maladaptive behaviors. This study participated in 335, 3-6 years typical preschoolers, carried out Short sensory profile, Vineland-II adaptive behavior scales. The study result in the sensory processing showed a significant positive correlation with the adaptive behavior, and a significant negative correlations were found in the internalizing/externalizing maladaptive behaviors. In the t-test, the problemtic group had lower adaptive behavior scores than the typical group. This study confirmed that atypical sensory processing affected not only adaptive behavior, but also internalizing/externalizing maladaptive problems, that sensory processing difficulties were more related to emotional and behavioral issues.

Purpose : Adolescent/Adult Sensory Profile is the questionnaire to evaluate sensory processing based on daily activities. Self-questionnaire commonly tends to be biased to the characteristics of subject, so its validity is low. This study aims to analyze correlation between questions of Adolescent/Adult Sensory Profile and tactile threshold measured from cognitive behavioral experiment. Methods : The tactile threshold was calculated by tactile detection task and tactile stimuli were provided with the consistent current stimulator. The tactile threshold was compared with results of tactile processing items in Adolescent/Adult Sensory Profile and statistical correlation analysis was performed. Results : Scores in Low Registration and Sensation Seeking had positive correlation with the tactile threshold and scores in Sensory Sensitivity and Sensation Avoiding had negative correlation with the tactile threshold. Among them, only Low Registration was statistically significant. Conclusion : The questions in Low Registration(Tactile Processing)are highly correlated with physiological characteristics. As a result, it was shown that sensory inflow is less, if the tactile threshold is high.

Objective : The purpose of this study was to define a standard score of Sensory Processing Scale for Children (SPS-C) and its concurrent validity by correlation with the Short Sensory Profile (SSP). Methods : The subjects were children enrolled in nurseries and kindergartens in Busan and Gyeongnam. We defined the standard score of the SPS-C and identified its concurrent validity for 337 children. Both the SPS-C and SSP instruments were used to assess the children's sensory processing ability. The collected data were analyzed using SPSS 24.0. A statistical analysis was used to define the standard score for SPS-C based on the mean and SDs of -1 and -2. To identify the concurrent validity of the SPS-C, the correlation between it and SSP was measured using Pearson's correlation analysis. Results : The ranges of total standard scores on the SPS-C were classified as follows: 115~160 indicated "Typical Performance"; 105~114 indicated "Probable Difference"; and finally, 50~104 indicated "Definite Difference." Concurrent validity was ascertained using the Pearson correlation between the total scores of the SPS-C and the SSP; the Pearson correlation coefficient was .755, indicating a statistically significant correlation. Conclusion : This study suggests the standard score of the SPS-C for interpreting results in clinical settings and confirms that it is a valid tool for evaluating children's sensory processing ability.
