emotional stimuli — into rewarding us every time we connect
with others online.
J.K. Rowling is a talented storyteller, but she has also used the style and technique of modern television and cinema media, which seizes the imagination by pummelling it, bombarding it
with powerful
stimuli, in a rapid pace,
with plenty of
emotional rewards.
The fear conditioning experiments, done
with live rats, showed that individual neurons in the amygdala, the
emotional hub of the brain, that were initially capable of telling apart safe from dangerous
stimuli can start firing indiscriminately — causing the rat to become fearful of non-threatening
stimuli.
The study is the first to examine how pupillary response to
emotional stimuli may interact
with life stress to predict prospective depression.
Getting stuck on threatening
stimuli is often associated
with difficulties in regulating negative
emotional experiences.
For example, thoughts return to the break - up, you experience feelings of loss and have
emotional responses to
stimuli associated
with the relationship, which can include flashbacks.»
The teens who receive our counseling services gain insight into how their life experiences drive their thoughts, feelings, and behaviors; learn to regulate their responses to
emotional stimuli; become more empowered to speak up and advocate for themselves appropriately; develop increased trust and the ability to choose healthier relationships; improve their school engagement; find compassion for themselves and each other; and experience renewed hope and a glimpse of a future
with new possibilities.
For many young people who exhibit
emotional disabilities — such as those on the autism spectrum — these expectations are not merely difficult to master; oftentimes, such a behavioral paragon falls outside the non-normative behavior practices that are important components of the way a child
with special needs communicates
with and responds to surrounding people and
stimuli (Picciuto 2016).
However, the most efficient method to create a strong positive
emotional response to
stimuli is to not only condition the response
with the first experience, but also to have the novel
stimulus (e.g., nail trimmers) precede the pleasant one (treat), as in the following steps:
A good approach in tackling dog fear is to invest in classical counterconditioning — a behavior modification technique meant to change the dog's
emotional response towards a feared
stimulus by encouraging an emotion that is incompatible
with fear.
By pairing the umbrella
with a positive
stimulus, such as a piece of sausage, the
emotional response gradually begins to change.
I will now look at you, where's my treat, where's my treat?!!» This therefore, accomplishes three things: it works to change the dog's
emotional response towards
stimuli yielding a more confident dog, it builds a better bond
with owner and it helps achieve better control, a win - win situation for all!
in the past about using counter-conditioning and desensitization to help dogs change their association
with fear - causing
stimuli in order to change their
emotional response.
Emotional vulnerability was defined as high distress reactions to fear
stimuli coinciding
with limited efforts by the infants to look at or seek assistance or comfort from their mothers.
Here, the
emotional responses of 23 BD participants were compared
with that of 24 healthy controls after various
stimuli; the study found greater HRV in the BD group after the
stimuli through an increase in measures related to parasympathetic activity.16 More recently, in 2015, Voggt et al investigated HRV features in 90 euthymic bipolar patients compared
with 62 healthy controls.
The amygdala is associated
with arousal and reactions to threatening
stimuli, as well as
emotional learning and memory.
Results indicated MBCT - C was associated
with increases in activation of the bilateral insula, lentiform nucleus, and thalamus, as well as the left anterior cingulate while viewing
emotional stimuli during the continuous processing task
with emotional and neutral distractors (CPT - END), and decreases in anxiety were correlated
with change in activation in the bilateral insula and anterior cingulate during the viewing of
emotional stimuli.
Several investigations found that conduct problems coupled
with low levels of CU traits are associated
with increased amygdala reactivity to fearful and angry facial expressions (Viding et al., 2012; Hyde et al., 2013; Blair et al., 2014; Sebastian et al., 2014), while those coupled
with high levels of CU traits are correlated
with decreased amygdala reactivity to
emotional stimuli, particularly fearful facial expressions (Odgers et al., 2008; Jones et al., 2009).
Neuroimaging studies
with healthy volunteers indicate that the FPC is associated
with allocating and maintaining attention on
emotional stimuli (Koechlin et al., 1999; Burgess et al., 2007; Tsujimoto et al., 2011).
As for ODD, studies have shown, as early as preschool age, that, compared to children
with low levels of CU traits and ODD, those
with higher levels of CU traits have more severe ODD problems, showing deficits in processing
emotional stimuli, such as fearful faces, having lower levels of fearfulness and anxiety, manifesting insensitivity to punishment and displaying physiological hypoarousal, such as low stress reaction — lower heart rate at rest and during reactivity to
emotional stimuli (Fanti, 2016).
This, along
with the higher activation seen before the presentation of
emotional facial
stimuli, implies that cues related to a secure figure can capture the attention resources, thereby affecting the performance in subsequent cognitive tasks.
Moreover, a study by Kimonis et al. (2006) used the Dot - probe paradigm (an attentional task that indexes attentional orientation patterns for
emotional stimuli)
with serious male adolescent offenders, revealing that those who had high levels of both CU traits and anxiety symptoms oriented significantly more their attention toward emotionally distressing pictures, as compared to those
with high levels of CU traits but low anxiety, who were not engaged by these
stimuli (Kimonis et al., 2012).
Therefore, the purpose of our study was to examine the priming effects of secure base schema on the processing of
emotional stimuli while exploring the interaction of this priming
with attachment orientations, and the underlying neural mechanisms.
Based on previous findings on attention to
emotional stimuli in children
with disruptive behaviors (e.g., Kimonis et al., 2012; Hodsoll et al., 2014), we hypothesized that higher levels of CU traits would be associated
with reduced attention toward fearful and angry faces, while higher levels of ODD - related problems would be associated
with greater attention toward both negative and positive (happy)
emotional faces.
Furthermore, to our knowledge, the present study is the first addressing the question on how children
with various levels of CU traits, anxiety and ODD - related problems process both negative and positive
emotional faces, by indexing attentional orientation patterns toward these
stimuli through a dynamic computation procedure.
The results showed that attachment secure priming interacted
with attachment anxiety to affect the processing of
emotional stimuli with both positive and negative valence.
Several behavioral research groups have provided evidence that attachment anxiety is associated
with a tendency for hypervigilance toward
emotional stimuli such as
emotional facial expressions (Niedenthal et al., 2002; Chris Fraley et al., 2006), and words associated
with threat (Mikulincer et al., 2004).
Other research has revealed that COAs have increased communication apprehension, more difficulty coping
with stressful events, and magnetic resonance imaging has shown that they respond differently to
emotional stimuli.
For instance, there is evidence of individual differences in expressing avoidance or hypervigilance
with respect to attachment threats: fearful avoidant individuals are in fact characterized by cognitive avoidance of all highly
emotional stimuli (Dewitte et al., 2007).
In terms of studies regarding behavioral problems, one extensive meta - analysis of the relationship between sleep deprivation and cognition in school - aged children found a significant increase in behavioral problems in children
with shorter sleep duration.25) Additionally, sleep deprivation resulted in a significant increment in alertness and
emotional reactivity in children, which led to delinquency, long - term emotional and behavioral difficulties.26 — 28) Consistent with such findings, sleep deprived subjects were more alert to negative stimuli, 29) and more susceptible to exaggerated aggressive impulses.30) Emotional lability and impulsivity were all strongly correlated with sleep deprivation, 31) with the severity of emotional dysregulation worsening as a function of the degree of sleep restri

Furthermore, people
with high levels of CU traits (psychopathic personality) have been shown to have three specific cognitive and
emotional deficits; a poor conditioned fear response, reduced ability to recognise fear, and deficits in
stimulus - reinforcement tasks (see Moul et al. [12] for a review).
Functional magnetic resonance imaging (fMRI) studies have provided evidence that individuals
with conduct problems and high levels of CU traits (CD / CU +) process
emotional stimuli differently from those
with conduct problems and low levels of CU traits (CD / CU --RRB-.
Our results are in line
with other neuroimaging studies that have found reduced activations to different kinds of affective
stimuli within the brain
emotional systems in violent adult subjects and in adolescents
with conduct disorder.
The latter traits, typically highly correlated, have been shown to correlate negatively
with trait mindfulness (Giluk, 2009) and are marked by negative
emotional reactivity to unpleasant life events (Goldberg, 1993) and neural reactivity to negative
stimuli (Canli et al., 2001).
