07 Apr A Good Excuse for Heuristic Logic
Dichotomous logic is useful for reasoning about form or the way things are. Function, or cause and effect, however, is fuzzier because observation may not be enough to exclude other processes that lead to the same result. Heuristic logic applies to function instead of form, prescribing actions based facts. Heuristics often operate at a relatively […]
03 Apr Causal Chains in Action
Expectations are often influenced by our understanding of cause and effect. In physical interactions between our bodies and the external environment, and in social interactions between other complex people, we are capable of predicting an outcome long before it actually comes to pass. We are also capable of predicting an outcome immediately before it comes to pass, as […]
02 Apr Context and Expectations
Expectations are context based, top-down ideas of what comes next. These top-down ideas feed perceptual processing centers in the brain, helping us focus on what matters, ,and sometimes blinding us to other possibilities. The two types of context we will consider today are sensory and non-sensory. Sensory context applies to anything in the physical world […]
01 Apr Generating and Qualifying Propositions
What are the limits of reasoning? Is it possible to reduce every cognitive activity (telling time, falling in love, inventing rockets…) to a set of premises and conclusions: propositions? LITTLE ANIMALS ARE FURRY is a very simple proposition. Can intelligence be defined by the complexity of the sequence of propositions we can balance in evaluating a situation? I […]
28 Mar Is Everything Black or White?
We have exercised our abstract ideas about that which is too big and chaotic for us to understand (everything), let’s take a glimpse at that which is so small and chaotic that we may never really figure it out: the workings of the mind. In the next few posts, we will examine different forms of logical […]
27 Mar Cognition and Emotion
I’m conflicted. I suspect you are too. “Since the time of the ancient Greeks, humans have found it compelling to segregate reason from passion, thinking from feeling, cognition from emotion. These contrasting aspects… have in fact often been viewed as waging an inner battle for control of the human psyche” (LeDoux, 1996, p. 24). In earlier […]
25 Mar Generalization and Inference
What do you do when you encounter something completely new, such as a new flavor. Can you identify that it is a flavor and that it resembles some flavors you’ve encountered before? If you knew about bridges from experience, but had never seen a drawbridge, or a lift bridge or a covered bridge, would you be able […]
24 Mar School of Hard Knocks
Are you a graduate of the School of Hard Knocks, or like me, are you still trying to escape the gravity of freshman year? Lessons about how altitude affects physical objects may be learned by slipping and falling down a few stairs. These lessons become ingrained early. Burned fingers have a profound impact. Notions of hot and cold, […]
22 Mar Common Sense and Thresholds
Finding Thresholds Threshold conditions are boundaries between states, and they exist everywhere, affecting everything. From a computational perspective, thresholds are a valuable tool for limiting the problem space to within manageable limits. In other words, knowing where the edges are can help us computationally color inside the lines. How could we determine a threshold? Observing, […]
