Brainwave entrainment is a colloquialism for 'neural entrainment', [25] which is a term used to denote the way in which the aggregate frequency of oscillations produced by the synchronous electrical activity in ensembles of cortical neurons can adjust to synchronize with the periodic vibration of external stimuli, such as a sustained acoustic ...
More relevant to frequency estimations but still a possible cause of the frequency illusion, the split-category effect is the phenomenon in which, when events are split into smaller subcategories, this can increase the predicted frequency of occurrence. [10] An example of this is asking a person to predict the number of dogs in a country or ...
The range–frequency compromise in judgment is a theory in cognitive psychology developed by Allen Parducci in the mid-1960s. Range–frequency is descriptive of how judgments reflect a compromise between a range principle that assigns each category to an equal subrange of contextual stimuli and a frequency principle that assigns each of the categories to the same number of contextual stimuli.
A heartbeat is an example of a limit-cycle oscillation in that the frequency of beats varies widely, while each individual beat continues to pump about the same amount of blood. Computational models adopt a variety of abstractions in order to describe complex oscillatory dynamics observed in brain activity.
This temporary depolarization of postsynaptic membrane potential, caused by the flow of positively charged ions into the postsynaptic cell, is a result of opening ligand-gated ion channels. These are the opposite of inhibitory postsynaptic potentials (IPSPs), which usually result from the flow of negative ions into the cell or positive ions out ...
The frequency format hypothesis is the idea that the brain understands and processes information better when presented in frequency formats rather than a numerical or probability format. Thus according to the hypothesis, presenting information as 1 in 5 people rather than 20% leads to better comprehension.
A Band-pass filter showing the centre frequency(Fc), the lower(F1) and upper(F2) cut off frequencies and the bandwidth. The upper and lower cut-off frequencies are defined as the point where the amplitude falls to 3 dB below the peak amplitude. The bandwidth is the distance between the upper and lower cut-off frequencies, and is the range of ...
In statistics, the frequency or absolute frequency of an event is the number of times the observation has occurred/been recorded in an experiment or study. [ 1 ] : 12–19 These frequencies are often depicted graphically or tabular form.
