Naloxone modulates visual judgments of similarity but not dissimilarity.
Endogenous opioids have been implicated in mediating (placebo) analgesia, in reward processes, and in the regulation of socially relevant emotions. To explore their potential contributions to higher cognitive functions, we used a novel task with tachistoscopically presented (for 150 ms) pairs of meaningless figures. Healthy right-handed men judged the similarities and dissimilarities between th...
متن کاملThe Difference of User Perception between Similarity and Dissimilarity Judgments
The similarity and dissimilarity is a corresponding relationship which is the base of cognitive judgments. The main purpose of this paper is to study the user perception by using similarity judgments. In this study, fifteen innovative products are used as the stimuli which divided into three groups: global, creative and local products. A total of 139 student volunteers participated in the vario...
متن کاملSemantic Contamination of Visual Similarity Judgments
The roles of semantic and perceptual information in cognition are of widespread interest to many researchers. However, disentangling their contributions is complicated by their overlap in real-world categories. For instance, attempts to calibrate visual similarity based on participant judgments are undermined by the possibility that semantic knowledge contaminates these judgments. This study in...

متن کاملDeep Convolutional Neural Networks Outperform Feature-Based But Not Categorical Models in Explaining Object Similarity Judgments
Recent advances in Deep convolutional Neural Networks (DNNs) have enabled unprecedentedly accurate computational models of brain representations, and present an exciting opportunity to model diverse cognitive functions. State-of-the-art DNNs achieve human-level performance on object categorisation, but it is unclear how well they capture human behavior on complex cognitive tasks. Recent reports...
