Abstract
This study aim to compare the cognitively biased information processing in anxiety, depression and was normal people. The study was causal-comparative study of 50 subjects anxious subjects, 50 subjects with depression and 50 normal subjects were formed by students of Tabriz University of Medical Sciences were selected using data Bvdnd.grdavry anxiety scales and Beck Depression scale psychological symptoms and clinical interviews, tests, and test complete root words were a reminder properties and data were analyzed using multivariate analysis of variance. The results showed that explicit and implicit memory between the three groups, anxious, depressed and normal in terms of positive, negative, and there was a significant threat, while threatening words of anxious, depressed subjects with negative words and positive words of ordinary scores were higher. But there was no significant difference in terms of neutrality between the three groups. It can be concluded that information processing in explicit and implicit memory bias creates and causes the information to be more consistent with the mood.

Abstract
The present study aimed to systematically review research investigating the relationship between diminished motivation and impaired capacity for pleasure (anhedonia) and the cognitive biases that exacerbate it. A systematic documentary review methodology was employed. Data were collected from 29 selected studies published between 2000 and December 2024, retrieved through searches in Scopus, PubMed, PsycINFO, and Google Scholar using relevant keywords, including anhedonia, cognitive biases, affective cognitive biases, and depressive disorder. Study quality was appraised using the Critical Appraisal Skills Programme (CASP) checklist, and data were analyzed via deductive thematic analysis. Findings indicated that anhedonia is primarily associated with deficits in pleasure anticipation and is directly linked to attentional, interpretative, memory, and self-referential biases. Consequently, even when individuals retain the capacity to experience pleasure, the presence of these biases disrupts decision-making processes and the effort required to pursue rewards. Furthermore, examining interaction between cognitive biases and anhedonia may inform the development of more precise cognitive–behavioral interventions and the design of evidence-based assessment tools and targeted treatments.
