a fairly common way to test for the word frequency effect is to
Word frequency effect Most studies looking at the word frequency effect use eye tracking data. When words have a higher frequency, readers fixate on them for shorter amounts of time.[8] In one study, participants' eye movements were recorded as they scanned single sentence stimuli for topic relevant words.[9] Researchers used an Eyelink eye tracker to record the movements of the participants' eyes. Reading times were found to be longer when focusing for comprehension due to increased average fixation durations. Results showed that reading for comprehension rather than scanning for certain words took longer fixations on the text.[9]
Sound Pitch is perceived as how "low" or "high" a sound is and represents the cyclic, repetitive nature of the vibrations that make up sound. For simple sounds, pitch relates to the frequency of the slowest vibration in the sound (called the fundamental harmonic). In the case of complex sounds, pitch perception can vary. Sometimes individuals identify different pitches for the same sound, based on their personal experience of particular sound patterns. Selection of a particular pitch is determined by pre-conscious examination of vibrations, including their frequencies and the balance between them. Specific attention is given to recognising potential harmonics.[15][16] Every sound is placed on a pitch continuum from low to high. For example: white noise (random noise spread evenly across all frequencies) sounds higher in pitch than pink noise (random noise spread evenly across octaves) as white noise has more high frequency content. Figure 1 shows an example of pitch recognition. During the listening process, each sound is analysed for a repeating pattern (See Figure 1: orange arrows) and the results forwarded to the auditory cortex as a single pitch of a certain height (octave) and chroma (note name).
