What does the research tell us about the positive effects of exercise on cognitive function? What are some of the specific effects that exercise can have upon cognition? Include a discussion of information processing speed and executive function

Expert Solution

It has been showed that moderate intensity exercise is related to increased performance in working memory and cognitive flexibility, whereas high-intensity exercise improves the speed of information processing. In this context, it has been reported that peripheral BDNF was significantly increased after high intensity exercise, but not after low-intensity exercise. In fact, it is evidenced that high-intensity exercise provides greater benefit to cognitive functions than low-intensity exercise in the elderly.

Persistent effects on cognition

In particular, consistent aerobic exercise has been shown to improve attentional control, information processing speed, cognitive flexibility (e.g., task switching), inhibitory control, working memory updating and capacity, declarative memory and spatial memory.

Processing speed isn't an executive skill, but it can affect executive function. Slow processing speed impacts working memory, flexible thinking, organization and planning, and attention skills. Mistaking slow processing speed for issues with executive function skills is common.

What does theory tell us about the effects of unskilled labor migration into a particular region?Specifically, discuss the intra-regional effects of this immigration on unskilled wages, product mix, and the returns to other factors (including, possibly, skilled labor, capital, and/or land). In your answer, contrast the predictions of the specific factors model with those of the Heckscher-Ohlin model, and state the assumptions you are invoking when discussing each. Finally, drawing on readings and class discussions, summarize the empirical evidence on...

(a) How do you find the second derivative of a function? (b) If both are positive numbers, what does that tell you about the function itself?

(a) How do you find the second derivative of a function? (b) If both are positive numbers, what does that tell you about the function itself? (c) If we know that a function is increasing, but at a decreasing rate, what does that say about the first and second derivatives? (d) Come up with a function where the first and second derivatives are non-zero but the third derivative is zero.

What can Cognitive science tell us about Information Processing? You should introduce traditional positions on these matters and show how Cogntive Science can either support or refute these, or lead to a reformulation/elimination of the question. My notes: so far the topics I am writing about: - Physical Symbol system - Fodor LOT and Modularity of Mind -Massive modularity Hypothesis -david Marr tri level hypothesis Any suggestions of alternate topics, how to structure the answer, what the conclusion should focus...
