DOI: 10.1016/j.biopsych.2015.12.007
Abstract: BACKGROUND Williams syndrome (WS), a genetic disorder resulting from hemizygous microdeletion of chromosome 7q11.23, has emerged as a model for identifying the genetic architecture of socioemotional behavior. Common polymorphisms in GTF2I, which is found within… read more here.

Replication in Imaging Genetics: The Case of Threat-Related Amygdala Reactivity
Sign Up to like & getrecommendations! Published in 2018 at "Biological Psychiatry"
DOI: 10.1016/j.biopsych.2017.11.010
Abstract: BACKGROUND Low replication rates are a concern in most, if not all, scientific disciplines. In psychiatric genetics specifically, targeting intermediate brain phenotypes, which are more closely associated with putative genetic effects, was touted as a… read more here.

Frontolimbic functioning during threat-related attention: Relations to early behavioral inhibition and anxiety in children
Sign Up to like & getrecommendations! Published in 2017 at "Biological Psychology"
DOI: 10.1016/j.biopsycho.2015.08.010
Abstract: Children with behavioral inhibition (BI), a temperament characterized by biologically-based hyper-vigilance to novelty, display threat-related attention biases (AB) that shape developmental trajectories of risk for anxiety. Here we explore the relations between BI, neural function,… read more here.

DOI: 10.1016/j.cobeha.2018.10.007
Abstract: Defensive motivation, broadly defined as the orchestrated optimization of defensive functions, encapsulates core components of threat-related psychopathology. The exact relationship between defensive functions and stress-induced symptoms, however, is not entirely clear. Here we review how… read more here.

Origins of sinister rumors: A preference for threat-related material in the supply and demand of information

DOI: 10.1016/j.evolhumbehav.2017.10.001
Abstract: Abstract Many rumors convey information about potential danger, even when these dangers are very unlikely. In four studies, we examine whether micro-processes of cultural transmission explain the spread of threat-related information. Three studies using transmission… read more here.

Childhood stress, grown-up brain networks: corticolimbic correlates of threat-related early life stress and adult stress response
Sign Up to like & getrecommendations! Published in 2017 at "Psychological Medicine"
DOI: 10.1017/s0033291717002628
Abstract: Abstract Background Exposure to threat-related early life stress (ELS) has been related to vulnerability for stress-related disorders in adulthood, putatively via disrupted corticolimbic circuits involved in stress response and regulation. However, previous research on ELS… read more here.

DOI: 10.1037/emo0001212.supp
Abstract: Acting in a goal-directed manner requires an ability to accurately predict the outcomes of one's actions. However, not much is known regarding how threat-related cues influence our ability to form action-outcome associations according to the… read more here.

DOI: 10.1038/s41598-017-17131-5
Abstract: Disruptions in fear-extinction learning are centrally implicated in a range of stress-related disorders, including anxiety and posttraumatic stress disorder. Given that these disorders frequently begin in childhood/adolescence, an understanding of fear-extinction learning in children is… read more here.

Trait anxiety predicts amygdalar responses during direct processing of threat-related pictures

DOI: 10.1038/s41598-021-98023-7
Abstract: Previous studies on the associations between trait anxiety and amygdalar responses to threat stimuli have resulted in mixed findings, possibly due to sample characteristics, specific tasks, and analytical methods. The present functional magnetic resonance imaging… read more here.

DOI: 10.1093/scan/nsx057
Abstract: Abstract Time-dependent variability in mood and anxiety suggest that related neural phenotypes, such as threat-related amygdala reactivity, may also follow a diurnal pattern. Here, using data from 1,043 young adult volunteers, we found that threat-related… read more here.

DOI: 10.1111/psyp.13332
Abstract: Visual features associated with a task and those that predict noxious events both prompt selectively heightened visuocortical responses. Conflicting views exist regarding how the competition between a task-related and a threat-related feature is resolved when… read more here.
