Cultural-historical activity theory (CHAT) is a theoretical framework [1] to conceptualize and analyse the relationship between cognition (what people think and feel) and activity (what people do). [2] [3] [4] The theory was founded by L. S. Vygotsky [5] and Aleksei N. Leontiev, who were part of the cultural-historical school of Russian ...
As an action potential (nerve impulse) travels down an axon there is a change in electric polarity across the membrane of the axon. In response to a signal from another neuron, sodium- (Na +) and potassium- (K +)–gated ion channels open and close as the membrane reaches its threshold potential.
Since the Psychology Today article gave the experiments wide publicity, Milgram, Kochen, and Karinthy all had been incorrectly credited as the origin of the notion of six degrees; the most likely popularizer of the term "six degrees of separation" was John Guare, who attributed the concept of six degrees to Marconi.

The Maastricht 7-jump involves seven steps, which are: [4] discuss the case and make sure everyone understands the problem; identify the questions that need to be answered to shed light on the case; brainstorm what the group already knows and identify potential solutions; analyse and structure the results of the brainstorming session
A positivistic approach to behavior research, TRA attempts to predict and explain one's intention of performing a certain behavior.The theory requires that behavior be clearly defined in terms of the four following concepts: Action (e.g. to go, get), Target (e.g. a mammogram), Context (e.g. at the breast screening center), and Time (e.g. in the 12 months). [7]

In behavioral science, an individual's emotions direct their response to current circumstances or relationships; thus, the action tendency, as a constituent factor of the ...

Neural backpropagation is the phenomenon in which, after the action potential of a neuron creates a voltage spike down the axon (normal propagation), another impulse is generated from the soma and propagates towards the apical portions of the dendritic arbor or dendrites (from which much of the original input current originated).
