Understanding factors that could influence feasibility and acceptability of brief CAT for adults who self‐harm
‘It just doesn't feel right’ and other reasons why some people fear and avoid positive emotions
The need to further our understanding of positive affect dysregulation in depression has been widely acknowledged. Two related relevant concepts in this realm, are Avoidance Of Positivity (AOP; referring to avoidance behaviour towards positivity) and Fear Of Positivity (FOP; referring to anxious or unpleasant feelings related to positivity). However, traditionally manifestations of AOP and FOP are considered in isolation, and self-report scales u…
Examining the relationship between anhedonia symptoms and trait positive appraisal style in adolescents
INTRODUCTION: Anhedonia, defined as a loss of interest and pleasure in previously enjoyable activities, is a core symptom of depression that predicts a poor treatment response in adolescents. We know little about the cognitive vulnerability factors that contribute to the development of anhedonia in youth. This cross-sectional and longitudinal survey study investigated the link between anhedonia symptoms and cognitive appraisal of positive affect.…
Interoception, contemplative practice, and health
Interoception can be broadly defined as the sense of signals originating within the body. As such, interoception is critical for our sense of embodiment, motivation and well-being. And yet, despite its importance, interoception remains poorly understood within modern science. This paper reviews interdisciplinary perspectives on interoception, with the goal of presenting a unified perspective from diverse fields such as neuroscience, clinical prac…
Learning and Affect Following Near‐Miss Outcomes in Simulated Gambling
Gambling near‐misses are non‐rewarded events that resemble a winning configuration. Past research using slot machines has shown that moderate rates of near‐misses increase gambling persistence, but the mechanisms supporting this persistence are unclear. One hypothesis is that near‐misses are mistakenly interpreted as signals of skill acquisition, supporting learning and fuelling the ‘illusion of control’. A slot machine simulation was administere…
Listening to Your Heart
Theories proposing that how one thinks and feels is influenced by feedback from the body remain controversial. A central but untested prediction of many of these proposals is that how well individuals can perceive subtle bodily changes (interoception) determines the strength of the relationship between bodily reactions and cognitive-affective processing. In Study 1, we demonstrated that the more accurately participants could track their heartbeat…
Ironic effects of emotion suppression when recounting distressing memories
Theories of ironic mental control posit that under conditions in which effortful control is compromised, for example, in laboratory manipulations of mental load or in those suffering from clinical levels of negative affect, attempts to suppress negative emotions can lead to a paradoxical increase in such feelings, relative to conditions in which no suppression is attempted. In line with this, we showed that high negative affect participants, when…
An investigation of the implicit control of the processing of negative pictures
The implicit control of emotion processing was investigated by varying encoding instructions for both negative and neutral pictures while measuring psychophysiological responses. Participants made comparative judgments about consecutive pictures for blocks of neutral or negative content. The highly specified judgment task was designed to minimize variance in the implementation of implicit control of processing. Affective modulation of startle amp…
