In the 1970s Craik and Lockhart proposed the levels of processing model. This model is based on a continuum of information processing, in which shallow processing involves the analysis of physical or sensory features, deeper level includes recognizing shapes and naming objects, while the deepest level involves interpretation and giving meaning. Even though the level of information processing is important for retention, forming the associations between the properties of the information also plays an important role in determining the probability of information retention. In addition to the depth of information processing, memory can also be affected by individual characteristics, among which personality traits stand out, explaining the consistent patterns of feelings, thinking and behaviour of the individual. Therefore, the aim of this thesis was to examine the influence of depth of information processing on the percentage of correct responses, reaction time and recall. An additional aim was to investigate the personality traits (neuroticism, psychoticism, and extraversion) as the predictors of recall. The study included 90 participants, who completed Cognitive Nonverbal Test, Peabody Picture Vocabulary Test, Eysenck Personality Questionnaire and computerizes word categorization task, which included perceptual and semantic condition. After this task, the participants were asked, without prior notice, to recall as many words as possible from the task. The results showed that participants achieved more accurate responses in the perceptual compared to the semantic condition. Given the reaction time, participants needed significantly more time to respond to stimuli in a semantic versus perceptual condition. In addition, participants recalled more words from the semantic compared to the perceptual condition. Among the personality traits, only psychoticism proved to be a significant predictor for the recall from the perceptual condition.
