- What is the core theme of Stokols' social ecology?
- Highlighting the dynamic relations between people and their surroundings.
- Social ecological models emphasize
a: individual health determinants
b: political health determinants
c: contextual (environmental) health determinants
d: the effect of culture on health
e: the effect of biology on health
- Though ecological models examine all of these, the emphasis is on contextual determinants (c), which also includes examination of politcal (b) and cultural (d) determinants
- Cite one of the arguments that Stokols uses to support his assertion that ecological models do better than those that focus on psychological and social circumstances.
- 1. The ecological model is more focused on people's physical surroundings-especially the joint influence of multiple life domains and settings(home, neighborhood, school, workplace)Thus the effects of phsyical space is given more emphasis than in psy/soc models.
2. In addition, ecological models emphasize the temporal aspects of the physical environment, eg primary, secondary, and tertiary levels of prevention are considered as may life-course analysis
3. ecological models try to describe the biological, psychological, sociocultural, and physical environmental factors that jointly affect well being
- name two (of three) things that Stokols thinks should guide the selection of problem in behavioral research
- 1. choose high leverage variables, ie those the exert the most effects across multiple levels of analysis (behavioral, interpersonal, organizational, community, & policy)
2. target the most prevalent and severe health problems
3. target highly vulnerable sub-groups
- Whereas McLeroy calls the ecological levels of analysis: individual, interindividual, organizational, community, and public policy, Stokols prefers what three terms?
- microinterventions - clinical
mesointerventions - organizational and community
macrointerventions - municipal, state, and national policies
- What does Stokols suggest is the reason for many of the failures to improve health through change of individual behavior?
- the individual is often not the primary source of the problem, thus changing the individual will not fix the problem - which may be environmental
- What practice does Stokols suggest the clinicians use to help them find the right leverage point with patients/clients?
- conduct what he calls an "environmental audit" to determine the psychologically salient settings and stressors in a person's life, eg workplace, home life, neighborhood
- What NCI interviewing technique does Stokols suggest to increase the skill of health care providers in assessing patient/client health problems?
- Use the NCI's 4A system: Ask, Advise, Assist, & Arrange help; also, provide about health-risk appraisal and self-care
- What remedy does Stokols suggest to improve practice at the mesointervention level?
- collaberation, cooperation, and coordination
- What does Stokols feel is generally the most potent intervention level?
- macrointerventions of city, state, or national policy
- One of the challenges of ecological planning is to create programs that are sustainable. What two things does Stokols suggest will aid in sustainability?
- 1. planning must be anchored in a "theory of intervention" that facilitates grass roots participation in the formation of policies by major stakeholder groups in the community
2. and that ensures that collaborative links among key organizations and interest groups will be established and maintained

- the law of effect
the law of readiness
the law of exercise
- What is the law of effect?
- a response followed by a satisfying stimulus or removal of annoying stimulus will be repeated (give yourself a reward every time you study)
- What is the law of readiness?
- satisfaction or annoyance depends on the neuronal readiness of the organism (study when your mind is fresh)
- What is the law of excercise?
- S-R connections are strengthened with use and weakened by disuse - though the effect is weak without response effects (the more you review the material the better you'll do on the test)

- What is R-type behavior?
- behavior controlled by its consequences
- What is instrumental behavior?
- behavior controlled by its consequences
- What is S-type learning a.k.a. classical or respondent conditioning?

- Wertheimer, Kohler, Koffka; Tolman & Lewin could also be named but they are known for more than they're gestalt thinking
- What is a gestalt?
- it's when you literally get it all at once or you don't; it's learning in whole chunks

- Wertheimer gave us the Phi phenomena. What is that?
- the perception of motion produced by a serious of still images. for example the classic "eat at joes" sign that has an "arrow" of flashing sequential lights creating a sense of movement toward Joes. When you "see" the illusion, that's a gestalt

- maladaptive responses & adaptive responses
- In protection motivation theory what determines the initial strength of the maladaptive response?
- the vaule of the intrinsic and extrinsic rewards for the maladaptive behaviors
- Rogers noted that maladaptive behaviors can be weakened by two beliefs:
- the belief that the threat is severe plus the belief that you are susceptible/vulnerable to it
- intrinsic extrinsic rewards minus serverity/vulnerability equals

- performance accomplishments: performance exposure; vicarious experience: live modeling; verbal persuasion: suggestion; emotional arousal: relaxation, biofeedback
- How does setting goals enhance motivation?
- Goals enhance motivation through self-reactive influences as follows: When individuals commit themselves to explicit goals, perceived negative discrepancies between what they do and what they seek to achieve, this creates self-dissatisfaction that serves as incentives for enhanced effort.

- First, the test must be able to detect the target condition earlier
than would be possible without screening and with enough accuracy to preclude large numbers

present on their own with signs or symptoms of the disease. In addition, the tests must be costeffective
and acceptable to the target population
