semantic processing

The term concreteness and emotionality effects refers to the reality that concrete and emotion words are processed faster and more accurately than abstract and neutral words. This effect has been observed in various cognitive tasks and several models have been proposed to account it. The aim of present study is investigating concreteness and emotionality effects on semantic processing in the Persian language using Event-related potentials. A quasi-experimental design, repeated measures is employed to examine concreteness as well as emotionality effects on visual word processing. 24 male students were taken by convenience sampling and set in the experimental condition that included a lexical decision task. The activation of neural networks was recorded while participants responded to concrete, abstract and emotional words. Comparison of related-potentials showed that emotional words elicited an early and more pronounced P300 than both concrete and abstract words. Nonetheless, concrete and abstract words evoked late and larger N400 and P600 In the second and third time windows respectively. The pattern of results suggest that concreteness effect in Persian is not entirely consistent with existing theories provided in this paper, so there may be an increased chance for other explanations to clarify the concreteness and emotionality effect on visual word processing in the Persian language.

Sensory and semantic information processing are two important factors in determining behavioral reactions. The aim of the current study was to compare of sensory and semantic information processing between borderline personality disorder people and normal ones. The descriptive study was causal-comparative (ex post facto) in design and the statistical population of the current study comprised of people who had registered to obtain services from the Psychiatric Center of Iran. The purposive sampling approach was adopted and thirty patients with borderline personality disorder (BPD) and thirty healthy controls were included in the study. Sensory and semantic information processing were assessed with Brown Adult Sensory Profile Questionnaire (BASPQ) and Osgood Semantic Differentiation Questionnaire (OSDQ). MANOVA test was applied to analyze data. The study's results were that individuals with BPD displayed significant differences in components of sensory sensitivity and sensation avoiding and all components of the semantic processing (life's component) (p
