Gating
|
allows you to pick and choose what to focus on
|
|
Huntington's Disease
|
inability to shut off unwanted movements, thoughts, images, or sensations; you can see the symptoms
Caused by the death of a neuron that is being replaced by spinal fluid (that is in the caudate) |
|
Obsession
|
an unwanted, irrelevant, often distressing thought or image (or impulse) that people cannot shut out from their consciousness; "feeling of anxiety"
|
|
OCD
|
an anxiety disorder; internal experience: an inability to gate unwanted, distressing information
obsessions > anxiety > compulsion |
|
Tourette's Syndrome
|
like a sneeze; inability to shut off unwanted sensations
Premonitory urge > discomfort > tic |

rituals designed to minimize the anxiety created by the obsession
|
|
The Gating System for the Brain
|
Information leaves cerebral cortex 'brain' > information descends into lower structures 'basal ganglia' > basal ganglia takes info from motor 'or cognitive' cortex, filters info and decides what gets through or not. By changing the gate you can shift the balance and create movement 'or consciousness'
Gate control can be involuntary or voluntary (preconscious or conscious) |
|
4 determinants of gating capacity
|
genetic, developmental, environmental, pathological
|
|
CSPT
|
Cortex > Striatum > Pallidum > Thalamus
|
|
Lateral Orbital Cortex Pathway
|
Lateral orbital cortex > Caudate > Globus pallidus > Thalamus > (back to LOC)
|
|
Anterior Cingulate Cortex Pathway
|
Anterior Cingulate Cortex > Nucleus accumbens > Globus pallidus > Thalamus > (back to ACC)
|
|
What happens when a loop is damaged?
|
When one loop is damaged, the other healthy loops must engage to compensate for the areas that are problematic
|
|
What is the process of dopamine through the brain?
|
ii. Dopamine regulates basal ganglia and frontal cortex > sends info to caudate nucleus > then into globus pallidus. Info ends on dendrites > dopamine input comes up from midbrain > terminates on neck > determines what info actually gets through
|

Movie (Falling Down, starring Michael Douglas)
|
"Throughout the film, his efforts at emotional control meet with frustration and failure, and it is only through violent and aggressive outbursts that he ever gets what he wants."
|
|
Underregulation - emotions
(Standards) |
people believe that they should never consciously attempt to control their emotions
Complete lack of standards - (venting sadness and other aversive mood states may parallel the underregulation proposed for anger) |
|
Underregulation - emotions
(monitoring) |
Disinhibition (silent seethers, when given alcohol may explode with anger)
Renegade Attention (involves focusing on feelings of anger or sadness - attentional failure) |
|
Underregulation - emotions
(Strength) |
Psychological inertia (distracters that backfire: mood state creates conditions that make it more difficult to escape from that mood)
Rumination (ruminating about a bad mood or brooding about what caused a bad mood is not likely to result in a mood change; reduces time and energy for active problem solving; increases the accessibility of negative cognitions) |
|
Misregulation - emotions
|
Misguided focusing (venting directs attention in the wrong place)
Emotional focusing (venting bad feelings prevents people from distracting themselves) Transcendence failure (attentional problem with alcohol, including myopia and transcendence failure) |
|
"Rolling the Snowball" - emotions
|
1) Spiraling distress (alcohol may intensify depressive symptoms; vicious cycle)
|
|
How to control anger?

|
TRUE
|
|
Compulsive buying disorder
|
loss of control over buying/shopping preoccupations, impulses or behavior, resulting in impairment in social or occupational functioning
|
|
Underregulation
(Monitoring) |
1) De-individualization (lost in a world of shopping and sometimes do not realize what they are buying)
2) Renegade Attention (reduced monitoring; subjects report being hypnotized by object) |
|
Underregulation
(Strength) |
1) Temporary weakness (impulse purchase while experiencing negative affective states)
2) Externally-mediated weakness (impulse is extremely strong and there is unlimited access) 3) Chronic weakness (can't control impulses) 5) Ego control (absorption: being self-involved in your experience; lack of ego control) |
|
Misregulation
|
i. Emotional focusing (regulation of emotions is more important to them than any other behavior)
ii. Painful self-awareness (many believe they are expert shoppers; low self esteem, positive interactions with store staff) iii. Transcendence failure ("cognitive narrowing": focus on immediate, low level, concrete task to avoid feeling bad about themselves, people focus on immediate things) iv. Overgeneralization (lacks seeing consequences of spending) |
|
Compulsive Buying
"Rolling the Snowball" |
1) Spiraling distress (shop as means of escaping or in efforts to improve their mood)
a) Preoccupation/ anticipation "craving" (irresistible urges > splurge > tension relief/high > regret/guilt > depression >> *urge*) b) Binge/intoxication (products associated with physical appearance; items often not used; urge to buy > loss of control > Intoxication > depression) c) Withdrawal/negative affect (relief after shopping episode short-lived; followed by negative feelings) 2) Acquiescence (unlimited access; making a purchases in a store requires a series of acts that could be restricted; leads to a description of an overwhelming power of the impulse) |
