itled, Function of the left planum temporale in auditory and linguistic processing, researchers attempted to determine the extent to which processes affecting the left planum temporale are restricted to linguistic utterances, or can be extended to sound forms of right-handed individuals. The study indicated that varying degrees of sensory activation occurred in the planum temporale dependent upon the listener’s active engagement with the process, with the planum temporale being more active to tones when the listener was actively engaged.
This is significant for the current study, as it indicates the level and type of word engagement affects the ultimate results regarding word recognition. When considering the implications, one could argue that the individual features of the study contributed to the results not being statistically significant. A possible example includes the uneven gender of the participants, as it’s possible that gender differences affect word recognition to differing degrees. Another reason is that the participants were all Junior level Psychology Students at Purchase. It’s possible that by limiting the study to this demographic, the results of the study were skewed.
Another example concerns the difficulty of the word lists used in the study. Past studies have indicated that the right ear advantage was most consistently gained when the study was complex. For instance, in a 1974 study titled Right Ear Advantage for Speech Presented Monaurally D.B. Fry discusses results that indicate right ear advantage was only triggered when a threshold level of complexity was passed. He writes:
…in a series of experiments with children in the age range 6-12 years…the speech materials used was series of digits or series of letter names and the measure of ear asymmetry used was correct recall of the series. While there was a trend towards REA (right ear advantage) for speech in the older children, the effect reached level of significance only for the
