Unemotional on all counts: Evidence of reduced affective responses in individuals with high callous-unemotional traits across emotion systems and valences
(Psychology Press Ltd, 2016)
The current study aimed to identify atypical neurophysiological activity associated with deficient affective processing in individuals with high callous-unemotional traits (CU). Fifty-six participants (M age = 20.52; 46% ...
Childhood callous-unemotional traits moderate the relation between parenting distress and conduct problems over time
(2014)
The present short-term longitudinal study examines the bidirectional effects among paternal-reported and maternal-reported involvement, distress and conduct-problems (CP) in children ages 7-12 years with callous-unemotional ...
Callous-unemotional traits in incarcerated adolescents
(American Psychological Association Inc, 2014)
The presence of callous-unemotional (CU) traits designates a subgroup of antisocial youth at risk for severe, aggressive, and stable conduct problems. As a result, these traits should be considered as part of the criteria ...
A startling absence of emotion effects: Active attention to the startle probe as a motor task cue appears to eliminate modulation of the startle reflex by valence and arousal
(2011)
Research has shown that during emotional imagery, valence and arousal each modulate the startle reflex. Here, two imagery-startle experiments required participants to attend to the startle probe as a simple reaction time ...
The better of two evils? Evidence that children exhibiting continuous conduct problems high or low on callous-unemotional traits score on opposite directions on physiological and behavioral measures of fear
(Cambridge University Press, 2015)
The present study examines whether heterogeneous groups of children identified based on their longitudinal scores on conduct problems (CP) and callous-unemotional (CU) traits differ on physiological and behavioral measures ...
Fearful victims and fearless bullies? Subjective reactions to emotional imagery scenes of children involved in school aggression
(2015)
Being aggressive has been related to fearlessness, low empathy and premeditated antisocial behaviors. The current study examined how school bullies and victims respond to affective situations presented through imagery. It ...
Emotion dysregulation in alexithymia: Startle reactivity to fearful affective imagery and its relation to heart rate variability
(2017)
Alexithymia is associated with deficiencies in recognizing and expressing emotions and impaired emotion regulation, though few studies have verified the latter assertion using objective measures. This study examined startle ...
Emotion processing deficits in alexithymia and response to a depth of processing intervention
(2014)
Findings on alexithymic emotion difficulties have been inconsistent. We examined potential differences between alexithymic and control participants in general arousal, reactivity, facial and subjective expression, emotion ...
Fetal programming effects of testosterone on the reward system and behavioral approach tendencies in humans
(2012)
Background: Sex differences are present in many neuropsychiatric conditions that affect emotion and approach-avoidance behavior. One potential mechanism underlying such observations is testosterone in early development. ...
Lost for emotion words: What motor and limbic brain activity reveals about autism and semantic theory
(2015)
Autism spectrum conditions (ASC) are characterised by deficits in understanding and expressing emotions and are frequently accompanied by alexithymia, a difficulty in understanding and expressing emotion words. Words are ...
