Do Shared S-minus Functions Among Stimuli Lead to Equivalence?
… in a reinforcement contingency by asking whether negative stimuli in a reinforcement contingency will also form an equivalence class, based on their shared function as S-minus stimuli. In Experiment 1, 5 subjects were tested for equivalence for positive and negative stimuli. Testing of positive …

The relationship between sleep and emotion regulation in individuals with depressive symptoms
… and tend to have high reactivity towards negative stimuli. Poor sleep in these individuals may contribute to increased emotional reactivity to negative stimuli, because sleep is known to modify reactivity to emotional, and especially negative, stimuli. This study aimed to investigate …

Emotional Memory: The Effects of Temporal Pressure on Episodic Memory
… proposes that under temporal pressure arousing negative stimuli delay binding of neutral items presented in close temporal proximity (as in lists with mixed neutral and negative stimuli). With fast presentation rates, a subsequent negative item may interrupt the binding process for the preceding …

Psychopathic Traits, Skin Conductance, and Emotion in the Normal Population
… of diminished psychophysiological responding to negative stimuli that incarcerated psychopathic individuals have shown. The callous affect (CA) dimension of psychopathy was expected to be associated with physiological differences as this is considered the core element of psychopathy. Level of CA …

Autonomic Nervous System Correlates of Emotion Regulation in Autistic Adults
… self-reported valence of viewing neutral and negative stimuli, and cognitive reappraisal used in daily life. There was also increased SCL and self-reported arousal and decreased self-reported valence to negative stimuli across the whole sample. Exploratory results also showed that SCL and …

Attention bias for negative semantic stimuli in late life depression and clinical research portfolio
… disengaging visual-spatial attention from negative information. Preliminary studies in depressed older adults provide evidence for the existence of biased attention to negative stimuli. However, the specific components of attention driving the detected bias effects in this population are …

Determining the effects of emotion on prospective memory performance
… of prospective memory, the use of emotional stimuli tends to lead to contradictory effects. Some studies suggest that emotional stimuli, particularly positive stimuli, lead to better prospective memory performance. However, emotional stimuli have also been associated with detrimental effects …

Emotional responsivity in people high and low in trait positive affect
… affect. Participants' reactions to emotional stimuli were assessed in two phases, a startle testing phase in which affective modulation of startle was assessed while participants viewed emotional pictures, and a picture rating phase in which participants rated the pictures on dimensions of …

Mood Effects and Individual Differences on Reappraisal and Distraction: An ERP Study of the Sensitivity of Emotion Regulation Strategies
… of emotions by using a regulation task with negative and neutral images to assess reappraisal and distraction ability. Specifically, this research evaluated the average amplitude of the latent positive potential (latent positivity, LPP) brainwave linked to distraction and reappraisal using an …

The Relationship between Involvement, Strain, and the Criminality of Fathers of At-Risk Children
… results from the removal of positively valued stimuli and the presence of negative stimuli. With such a theory, criminologist had focused on how this may explain juvenile delinquency. Yet very little attention was given to how this may affect adult criminality as well. Similarly, Hirschi (1969) …

Attentional Bias Modification: An Examination of Novel Training Contingencies and Stimulus Pairs
Selective attention to dysphoric stimuli is hypothesized to contribute to the onset and maintenance of emotional disorders. Over the past two decades, research on training and modifying attention as a form of treatment for anxiety and depression, Attentional Bias Modification (ABM) treatment, has …

SHARED AND UNIQUE PATTERNS OF RESTING-STATE FUNCTIONAL CONNECTIVITY LINKED TO ATTENTIONAL AND INTERPRETATION BIASES
… prioritize their attentional focus on more negative stimuli and interpret ambiguous emotional information as more negative. A great effort has been dedicated in recent years to identifying the neural mechanisms of cognitive bias, especially attentional bias. However, studies examining how …

Influence of negative affect on false memory production
This thesis investigates the effect of negative emotion induction on the production rate of false memories. False memories are a significant concern for situations in which the accuracy of memory is relied upon or called into question. Within the legal system eyewitness testimonies may often be the …

The Effects of Age and Task on Visual Emotion Processing
… adults’ perception of and attention to facial stimuli are enhanced by positive and negative emotional expressions, with negativity leading to a greater benefit than positivity. Conversely, older adults demonstrate a positivity bias, devoting more attention to positive stimuli and less to …

The Relationship Between Affect in Dreams and Emotional Memory Consolidation
… secondary analysis revealed that an increase in negative affect in dreams predicted better memory retention of negative information. Increased negative affect may create a need for increased mental processing and, in turn, support better memory consolidation. These findings have implications for …

Preventing guilt by association: Mindfulness and susceptibility to evaluative conditioning
… in which a stimulus is evaluated as positive or negative based on repeated pairings with valenced stimuli. Emerging evidence suggests that individuals differ in susceptibility to EC and these differences may be related to various social and psychological biases. One variable that has been linked …

Effects of augmentation agents on emotional memory consolidation and subliminal cue exposure to fear-relavent stimuli
… DCS demonstrated differential memory for negative stimuli, in that memory for negative items was significantly worse for individuals taking a single dose of DCS. Study 2 examined the effect of DCS in a two-day design on extinction learning through a subliminal cue paradigm that activates …

A Mixed Emotions Framework And Its Applications In Affective Computing

Neural Mechanisms Involved in Emotion /Attention Interactions
… anxiety groups showed greater interference from negative stimuli. Control and depression participants showed a stronger positive dACC-DLPFC relationship for negative versus neutral words, indicating greater dACC-DLPFC implemented control in the presence of negative distractors. In contrast, …

Immediate and long-term effects of emotion regulation: an eye-tracking investigation of focused attention on emotional experience and memory
Emotional stimuli tend to capture attention and this may lead to an immediate increase in our subjective emotional experience, as well as to longer-term enhancing effects on our memory for emotional stimuli. In extreme circumstances, increased emotional reactivity to negative stimuli may become …
