Introduction. Both Channon, Baker, and Robertson (1993) and Hartlage, Alloy, Vazquez, and Dykman (1993) claim that working memory impairment in depressed patients is limited to Baddeley's (1996) central executive and does not affect either the phonological loop or the visuospatial scratchpad. Our key questions were: (1) is there an impairment of working memory in depression and which elements does it effect; (2) is another major clinical group also affected and in what ways, and finally, (3… 
Exploring the role of working memory and understanding educational underachievement in anxiety and depression.
Research has shown that high levels of emotion are associated with lowered academic performance. However, the mechanisms involved in this relationship are as yet unclear. One potentially important
The Efficacy of Working Memory Training on Working Memory Capacity, Psychopathology, and Mental Well-being
markdownabstract__Abstract__ Mood and anxiety disorders are the most prevalent psychopathological disorders in the Netherlands (de Graaf, ten Have, Van Gool, & Van Dorsselaer, 2012). Anxiety
Anxiety and working memory capacity: A meta-analysis and narrative review.
TLDR
A narrative review of the literature revealed that anxiety, whether self-reported or experimentally induced, is related to poorer performance across a wide variety of tasks and identified a number of methodological limitations common in the literature as well as avenues for future research.
Examining Working Memory Performance in Adult Psychosomatic Inpatients
TLDR
Screening for the presence of high RNT levels, severe depressive symptoms or higher age may help to identify patients with impaired WM functioning and to intervene on these important patient characteristics early in the rehabilitation process.
WORKING MEMORY IMPAIRMENTS IN PATIENTS WITH MAJOR DEPRESSIVE DISORDER
TLDR
Depression is associated with impairment of working memory, and the amount of impairment increases along with the increase in the severity of depressive symptoms.
Schizophrenia and depression: The relation between sleep quality and working memory.
Investigating the mediating effect of working memory on intentional forgetting in dysphoria
TLDR
It is suggested that working memory training might be a viable intervention for improving the ability of depressed individuals to prevent unwanted memories from coming to mind.

Distraction and depressive cognitions
Recent advances in the treatment of depression have focused on the cognition of patients, not as a symptom of depression but as a probable cause. Research supporting such developments focuses on
The Cognitive Failures Questionnaire (CFQ) and its correlates.
TLDR
A questionnaire measure of self-reported failures in perception, memory, and motor function, the most plausible view is that cognitive failure makes a person vulnerable to showing bad effects of stress, rather than itself resulting from stress.
Verbal Learning and Memory in Elderly Depressives
TLDR
The nature of the verbal learning impairment of elderly depressed patients was studied by comparing their performance with that of remitted depressives and of dementing patients, with depressives tending to make less random errors and produce fewer false positives than the dements but to make more transposition errors.
Cognitive function in depression: its relationship to the presence and severity of intellectual decline
TLDR
The distribution of global cognition was found to be normally distributed in the sample of 29 patients assessed, and there was a gradient of dysfunction across the three patients groups, indicating which aspects of cognitive function are most sensitive to the intellectual decline seen in depression.
Remembering with and without awareness in a depressed mood: evidence of deficits in initiative.
We propose that depressive deficits in remembering are revealed in tasks that allow the spontaneous use of strategies; tasks that bypass or direct the use of strategies should not produce depressive

Abstract Anxiety often impairs performance of “difficult” tasks (especially under test conditions), but there are numerous exceptions. Theories of anxiety and performance need to address at least two
Impaired attention in depressive states: a non-specific deficit?
TLDR
The limited neuropsychological literature on impaired attention in depressive states is reviewed, with emphasis on areas where the findings of modern cognitive research might be applied in the future to design more sophisticated tests of attentional impairment.
Working memory in clinical depression: an experimental study
TLDR
It is suggested the articulatory loop and visuospatial sketch pad components of working memory to be unimpaired in depression and likely to involve central executive function.
