“…Consummation refers to the liking experience, or the positive emotions elicited by satiation ("liking effects" using Berridge terminology). This dual distinction of the hedonic capacity has been well captured in humans using psychometric measures and neuroimaging techniques (Mallorquí et al, 2014).…”

“…In recent years, anhedonia has gained interest in health beyond psychiatric disorders (Assogna et al, 2011;Treadway and Zald, 2011;Loas, 2014;Mallorquí et al, 2014;Ritsner, 2014a,b). Its transdiagnostic features and presence in non-clinical samples (Harvey et al, 2007) have stimulated new lines of clinical research that highligh the crucial role of anhedonia in chronic health conditions, such as chronic pain.…”

Anhedonia is the diminished motivation and sensitivity to pleasurable stimuli. It has been reported to be more prevalent in patients with chronic pain as compared to healthy controls. Endometriosis is a chronic inflammatory systemic disease with a significant psychosocial impact that compromises wellbeing and the day-to-day life of patients. Women with endometriosis show significant psychological distress, even more pervasive when chronic pelvic pain is present. In the current review we will discuss the role of anhedonia in endometriotic chronic pelvic pain. We will also present new lines of research that could lead to more fully clarifying the psychological impact of endometriosis and its detrimental repercussions to quality of life and mental health.

“…Yet, few studies have explicitly examined the relationship between individual differences in reward-related deficits and valenced cognition in depression, much less distinguished between different reward-related processes such as reward responsivity and approach motivation. Of the studies that have been conducted, most focus on a single cognitive processes such as memory (Damme et al, 2019;Liu et al, 2012;Olsen, Bjorkquist, Bodapati, Shankman, & Herbener, 2015), attention (Brailean, Koster, Hoorelbeke, & De Raedt, 2014), or self-referential processing (Kircanski, Mazur, & Gotlib, 2013), or psychophysiological processes believed to measure these processes (e.g., the P300, N170, and LPC components of event-related potentials; Chen et al, 2014;Mallorquí, Padrao, & Rodriguez-Fornells, 2014) and do not study depression on a dimensional basis (i.e., only recruit on a categorical basis, by diagnostic group). These studies suggest that deficits in reward-related processes may be associated both with biases for positively-valenced information and negatively-valenced information in depressed individuals.…”

Background: Individual differences in reward-related processes, such as reward responsivity and approach motivation, appear to play a role in the nature and course of depression. Prior work suggests that cognitive biases for valenced information may contribute to these reward processes.Yet there is little work examining how biased attention, processing, and memory for positively-and negatively-valenced information may be associated with reward-related processes in samples with depression symptoms. Methods:We used a data-driven, machine-learning (elastic net) approach to identify the best predictors of self-reported reward-related processes using multiple tasks of attention, processing, and memory for valenced information measured across behavioral, eye tracking, psychophysiological, and computational modeling approaches (N = 202). Participants were adults (ages 18 -35) who ranged in depression symptom severity from mild to severe.Results: Models predicted between 5.0-12.2% and 9.7-28.0% of held-out test sample variance in approach motivation and reward responsivity, respectively. Low self-referential processing of positively-valenced information was the most robust, albeit modest, predictor of low approach motivation and reward responsivity. Conclusions: Self-referential processing of positive information is the strongest predictor of reward responsivity and approach motivation in a sample ranging from mild to severe depression symptom severity. Experiments are now needed to clarify the causal relationship between self-referential processing of positively-valenced information and reward processes in depression.

“…It is further divided into consummatory, motivational, anticipatory, and decisional sub-types. The first refers to the loss of the subjective experience of pleasure (or positively-valenced affect) from partaking in previously enjoyable activities, the second to a loss of interest or motivation in pursuing such activities, the third to a diminished ability to anticipate future pleasure on the basis of past experiences, and the fourth to difficulties in choosing different courses of action due to indifference regarding their consequences (Mallorquí, Padrao, & Rodriguez-Fornells 2014;Treadway & Zald 2011). There is significant debate over whether these four symptoms should fall under the same label (Treadway & Zald 2011), as they seem to be conceptually and diagnostically separable phenomena (Oyebode 2015: 262, 296).…”

Anhedonia and the Affectively Scaffolded Mind

King's College London, UK Anhedonia, roughly defined as the diminishment or absence of the capacity to experience pleasure or joy in the performance of daily activities, is a core symptom of Major Depressive Disorder, as well as other psychiatric illnesses. I argue that the two major psychological theories of anhedonia are committed to the view that anhedonia depends, in the general case, on more than just neurobiological states and processes. This is despite the overwhelming explanatory focus on neurobiological factors in the existing literature, which reflects a general commitment to biomedical materialism, the view that mental illnesses are simply neural dysfunctions (Davies 2016; Zachar 2000). Instead, I argue that anhedonia depends upon the breakdown in the function of what Colombetti and Krueger (2015) term a subject's affective niche. Since affective niches are composed of elements of a person's natural and social environments, including artefacts, activities, and other people, anhedonia likewise turns out to depend on a subject's environment, in a manner that makes it generally inscrutable within the boundaries of skin and skull. I discuss and refute some objections to this view, and conclude by sketching a promising, general strategy one could adopt to refute biomedical materialism for a non-trivial class of other psychiatric symptoms. 1. Specifically, the nucleus accumbens and frontostriatal network.
