THE NONLINEAR PERCEPTION OF SOUND INTENSITIES: TIME-INTENSITY TRADES AND THE INTERACTIONS OF FORWARD AND BACKWARD MASKING

Unknown Date (has links)
Masking is said to have occurred when one stimulus interferes with the perception of another. When masking sounds both precede and follow a test sound, the perceptual interference they produce often exceeds the sum of their individual effects. / The present study considers an explanation for this phenomenon based on certain properties of the auditory system's mechanical and neural responses to transient sounds. It is assumed that: (1) the system constructs a preliminary internal representation of the sound's intensity that has a latency inversely related to intensity, (2) the function relating latency to intensity is nonlinear (concave upward), (3) the magnitude of the intensity representation is subsequently compressed--transformed according to a function whose shape is concave downward, and (4) one effect of a preceding masker resembles a simple attenuation of the sound that is masked. One consequence of these assumptions is that a preceding masker will delay the internal representation of the test stimulus more than it will delay the representation of a masker that follows the test stimulus. Thus, combining maskers in this way should produce 'additional masking' that is essentially an increase in the effectiveness of the second masker. / Some psychophysical measurements are described that appear to confirm this interpretation. Two novel interactions of combined maskers were observed in these experiments. One of these was predicted by the model outlined above. The other was not, but could be accounted for by a small modification of the model. / Source: Dissertation Abstracts International, Volume: 41-10, Section: B, page: 3922. / Thesis (Ph.D.)--The Florida State University, 1980.

SERIAL POSITION EFFECTS IN VISUAL MEMORY: THE EFFECTS OF REPETITION ON ITEM AND ORDER INFORMATION

Unknown Date (has links)
In three experiments the conditions under which serial position effects might be obtained in recognition measures of memory for complex pictorial stimuli were explored. A two-alternative, forced-choice probe recognition test was employed to assess the retention of complex pictures. In addition, memory for the serial position of a picture in a list was measured. In Experiments 1 and 2, recognition of pictures was assessed after varying numbers of presentations of a study list to determine whether serial position effects are obtained as a function of prior familiarity with target stimuli. Recognition of pictures was found to deteriorate gradually as a function of serial position with no evidence for a recency effect. Repeated study of a list improved performance on the retention test but did not interact with serial position. / The purpose of Experiment 3 was to assess the effect that loss of episodic information (e.g., where and in which list a picture had been seen) might have on recognition memory as a function of serial position. Episodic forgetting was enhanced by the presentation of pictures in several different lists. A two-alternative, forced-choice test that contained both the target picture and a picture that occurred in an earlier list was employed to assess the effect of episodic forgetting. Recognition performance was affected by the different types of test used in Experiment 3. However, there was no change in recognition performance as a function of serial position. / In contrast to the relatively flat serial position functions obtained for the recognition of target pictures, bow-shaped serial position functions demonstrating both primacy and recency effects were obtained for the retention of serial order information in all three experiments. It was concluded that although there is evidence for elaborative post-stimulus processing of visual information (e.g., Graefe & Watkins, 1980; Intraub, 1980; Weaver & Stanny, 1978), this processing is probably terminated when a new to-be-remembered picture appears. Furthermore, it is suggested that maintenance rehearsal cannot be given to complex pictorial stimuli. / Source: Dissertation Abstracts International, Volume: 42-03, Section: B, page: 1214. / Thesis (Ph.D.)--The Florida State University, 1981.
