Background: Autobiographical memory (AM) presents components related to the type of memory and may present an associated emotional valence. Comparing healthy older adults, adults with mild cognitive impairment (MCI), and adults with Alzheimer's disease (AD) gives contradictory results. We examined AM in these groups to analyze differences and provide information that would contribute to the understanding of AM and associated emotional deficits in patients.
Method: 31 AD, 32 MCI, and 32 healthy older adults were evaluated using the Autobiographical Memory Test. Taking the number of memories elicited in each category as a dependent variable, an ANOVA of three groups x 3 types of valence was applied (positive, negative, neutral, intrasubject), and another ANOVA of 3 groups x 3 types of memory (specific, general, vague, intrasubject).
Results: Specific-type responses are reduced with the progression of the pathology and in addition healthy subjects have a positive valence while AD presents a mainly neutral valence.
Conclusions: Cognitive problems associated with aging tend to affect the highest level of AM specificity. Healthy subjects and MCI have memories with an emotional valence, whereas the AD group has a significant deterioration in these memories.

The present study investigated the influence of emotional stimuli in the flanker task. In six experiments, separate influences of anticipating and reacting to valence-laden stimuli (affective pictures or facial expressions) on the flanker effect and its sequential modulation (also known as conflict adaptation) were examined. The results showed that there was little evidence that emotional stimuli influenced cognitive control when positive and negative stimuli appeared randomly during the flanker task.

Background: Over the past years, social cognition has been envisaged as a promising domain to distinguish behavioral variant frontotemporal degeneration (bvFTD) from its main differential diagnoses that is primary psychiatric disorders (PPD). The core-processes approach, which has emphasized the importance of emotion recognition and mentalizing, has been particularly useful to better characterize each condition and enhance the earliness of FTD's diagnosis. However, new findings evidencing conflicting results regarding the ability of social cognition to distinguish bvFTD from PPD have underlined the importance of moving beyond the core processes approach.

Introduction: Approach and avoidance behaviors have been extensively studied in cognitive science as a fundamental aspect of human motivation and decision-making. The Approach-Avoidance Bias (AAB) refers to the tendency to approach positive stimuli faster than negative stimuli and to avoid negative stimuli faster than positive ones. Affect and arousal in involved individuals are assumed to play a crucial role in the AAB but many questions in that regard remain open.

Stress has been considered as a major risk factor for depressive disorders, triggering depression onset via inducing persistent dysfunctions in specialized brain regions and neural circuits. Among various regions across the brain, the lateral habenula (LHb) serves as a critical hub for processing aversive information during the dynamic process of stress accumulation, thus having been implicated in the pathogenesis of depression. LHb neurons integrate aversive valence conveyed by distinct upstream inputs, many of which selectively innervate the medial part (LHbM) or lateral part (LHbL) of LHb.

The ventromedial prefrontal cortex is widely linked with emotional phenomena, including appraisal, modulation, and reward processing. Its perigenual part is suggested to mediate the appetitive value of stimulation. In our previous study, besides changes in evoked MEG responses, we were able to induce an apparent behavioral bias toward more positive valence while interpreting the ambiguous, morphed faces after the effect of excitatory tDCS stimulation of the perigenual ventromedial cortex (pgVM).
