Signal threshold psychology
WebAn approach to resolving this dilemma is provided by signal detection theory. This approach abandons the idea of a threshold. Instead, the theory involves treating detection of the … WebThe neuron’s threshold is the electrical value that determines whether the neuron fires, sending an electrical signal from its axon to synapses with other neuron dendrites. A neuron performs one function and it does it very well. It aggregates the potential coming in across its 10,000 dendrites. If the.

Imagine SD=1, mean A = 0, mean B = 1, with B>A as the "correct" answer (perhaps B is the signal, and A is the noise). This will give you a d' of 1 because the difference between the means is 1, divided by a standard deviation of 1. ...
