Lecture 6: Motivation Reading: Weiten CH 10 Immediate Sources of Motivation: What drives the tasks we attempt on a day to day basis? (IMMEDIATE) SO: what elicits behaviour? Automatic behaviour = reflexes and instincts Learnt behaviour = classical conditioning ( conditioned stimuli) & instrumental learning ( discriminative stimuli) Stimulus Control - Habit Learning Motivation = Why individuals initiate choose or persist in specific actions in specific circumstance

pass through. 3. What is diffusion and why does it occur? A: The movement of solutes in a solution from high to low concentrations. Diffusion occurs because particles of a substance will move to the less concentrated areas until equilibrium or homeostasis is reached. 4. Compare and contrast diffusion‚ osmosis‚ and facilitated diffusion.

Studies that have mapped the connections between neurons in the brain‚ gain insight into the regulation of appetite and metabolism. The ARC and VMH has long been thought of as satiety centers. Studies that investigate the role of the arcuate nucleus in the hypothalamus‚ in regulating appetite and metabolism‚ have targeted two chemically identified neuronal types within the ARC: anorexigenic pro-opiomelanocortin (POMC) neurons and orexigenic neuropeptide Y (NPY)/agouti-related peptide (AgRP) neurons

(Connett & Sahlin‚ 1996). Contractions require energy in the form of adenosine tri-phosphate (ATP). ATP stores in muscle are around 8mmol/l and are exhausted within 2s of exercise (Connett & Sahlin‚ 1996). To continue exercise and maintain ATP homeostasis‚ ATP production must increase rapidly. The adaptations that occur are tailored to suit the energy requirements of the exercise‚ therefore the adaptations during marathon running are different to those seen during sprinting.

Homeostasis = Body wisdom ↓ ↓ Steady state * Homeostasis keeps us healthy * The means by which organisms (our body) maintain a constant internal environment in spite of fluctuations in the external environment. * This means humans have narrow limits we have to keep. 1.
