Biological Approach

 

 

 

 

1.  Discuss the use of brain imaging technologies in investigating the relationship between biological factors and behaviour.

 

AnnaRose Childress – Cravings and observed with PET scan

Bremner – MRI & PET in PTSD

Corkin - HM

Breiter – Injected woman with Cocaine and observed using fMRI

 

2.  Evaluate studies related to localization of function in the brain.

 

            Lashley – In search for the Engram

          Corkin – HM

AnnaRose Childress – Cravings and observed with PET scan

Bremner – MRI & PET in PTSD

Breiter – Injected woman with Cocaine and observed using fMRI

 

3.  To what extent does neuroplasticity effect the brain and human behavior.

 

Lashley – In search for the Engram

Rosenzwieg - More Experience = Bigger Brain

Merzenich - Somatosensory Plasticity

 

4.  Using one or more examples, explain effects of neurotransmission on human behavior.

 

Neurons, Synapses, Action Potentials, and Neurotransmission

George Koob – Inserted probe and measured dopamine in rat’s brain

Caspi - Influence of Stress on Depression

Sapolsky – Stress and Depression

AnnaRose Childress – Cravings and observed with PET scan

Breiter – Injected woman with Cocaine and observed using fMRI

 

5.  Discuss neural networks and their effect on human behaviour.

 

Neural networks consist of a series of interconnected neurons

George Koob – Inserted probe and measured dopamine in rat’s brain

Caspi - Influence of Stress on Depression

Sapolsky – Stress and Depression

AnnaRose Childress – Cravings and observed with PET scan

Breiter – Injected woman with Cocaine and observed using fMRI

 

 

6.  Using one or more examples, discuss functions of two hormones in human behaviour.

 

Sapolsky – Why zebras don’t get ulcers – Chap 10 and Chap 2

Selye - General Adaptation Syndrome

Cannon - Fight or Flight

 

7.  To what extent do pheromones influence human behaviours?

 

Cutler - Pheromonal Influences

Lundstrom - Phermones affect mood in women

Hare - Phermones do not affect perception

 

8.  Evaluate studies on genetic similarities.

 

Basic Genetics

Bouchard - Genes Enviroment and Personality

Kendler - Twin Study on Depression

Shuckit - genetic markers in alcoholism 

 

9.  Discuss two effects of the environment on genetic expression.

 

Caspi - Influence of Stress on Depression

Weaver - Epigenetic Programing by Mom

Vucetic - Maternal high fat diet alters methylation of dopamine

 

10.  Evaluate one evolutionary explanation of behaviour.

 

Cook and Mineka – Bio preparedness and fear of snakes

Ohman and Mineka - The Malicious Serpent

LoBue - Snake in the grass

 

11.  Discuss ethical considerations in research into genetic influences on behaviour.

 

Who owns and controls genetic information?

Should employers, insurance companies, courts, schools, or the government have access?

Would you want to know if you are pre-disposed to develop a disease which has no cure?

Should parents have genetic testing done on themselves?  Or on their children?  Should parents be able to choose to abort a fetus based on the results of genetic testing?

Are criminals who are found to be strongly genetically predisposed to a certain behavior responsible for their crimes?

Caspi - Influence of Stress on Depression

Kendler - Twin Study on Depression

Shuckit - genetic markers in alcoholism

 

12.  Discuss how and why particular research methods are used with the biological approach.

 

          Any Cognitive studies could be used for this.  Pick two experiments and then one or two that are a different method.  Or you could do three methods and one study each.  Just be sure do discuss How and Why the methods are being used and use your studies to illustrate this.

 

13.  Discuss ethical considerations related to research studies with the biological approach.

 

          You need at least two ethical considerations.  Deception should be one.  Pick another one like lack of informed consent or confidentiality and use 3 or 4 studies that illustrate the considerations.
