|
|
Freud & Behaviorists (1880)
|
1. Early experience is important
2. "Anxiety" can cause neurosis - introduction to idea of environment as important player
3. Anyone with sufficient anxiety can have psychopathology
|
|
Bowlby (1960s)
|
Early experience is important - measures attachment around the world

|
Hubel and Wiesel (1960s)
|
researchers who investigated critical periods for vision

|
|
low reactives
|
lowest rates of any disorder, including externalizing disorder, 60% report no disorder of the kinds measured
|
|

|
Kagan asserts that inhibited temperament is the result of an overactive _______________
|
|
amygdala
|
- more active when observing threatening faces of fearful faces
- more active in situations of uncertainty - going beyond fear
|
|
right/left alpha asymmetry
|
- refers to the amount of power in the a______ spectrum (~8-12 Hz) in electrical activity records at the scalp or brain waves

thicker in individuals with inhibited temperament/ high amygdala activation

|
|
learning and cognitive styles
|
intrapersonal risk factors for anxiety disorders
|
|
fear conditioning
|
increased fear learning following traumatic exposures or predisposition
- learning without intending to acquire it --> UCS becomes CS to trigger CR
|
|
Cognitive styles
|
- a risk factor for anxiety disorders
includes: (JIMA)
attentional bias towards threat, memory bais towards threat, interpretive bias, and judgement bias
|
|
attentional bias towards threat
|
in novel situations, attention is captured by negative stimulus
|
|

|
interpretive bias
|
ambiguous stimuli are interpreted as threatening
|
|
judgment bias

interpreting situations as not in one's control --> can increase anxiety
|
|
observing fear behavior in others, hearing others speak fearfully, and escape conditioning

how do children acquire difference in cognitive style and learning about anxiety?
