“…In summary, Experiment 1 provides two main findings. First, it confirms previous data showing a reoccurrence of the primacy effect on the second sound part of a frequency band when this band contained a gap (Fischenich et al, 2020). In conditions where a band contained a gap, the weight assigned to the first segment of that band following the gap was higher than the weight assigned to the same segment when the band did not contain a gap.…”

“…Two gap durations were used to assess potential differences in the pattern of the weights due to the gap duration. Such differences were observed in previous work on temporal loudness weights of sounds including a temporal gap (Fischenich et al, 2020).…”

“…Also, we presented a slightly longer gap duration of 700 ms compared to the 500 ms in Experiment 1. The reoccurrence of the primacy effect after a silent gap was reported to be more pronounced at longer gap durations (Fischenich et al, 2020). As a consequence, the presence or absence of the 700-ms gap was expected to cause a stronger change in the weights on the "context band" than for a 500-ms gap, and thus to provide a stronger test of our hypothesis that the temporal weights assigned to a given FIGURE 4 | Bayes factors (BF 01 ) as a function of prior width for the four different panels of Figure 3.…”

“…Pedersen and Ellermeier (2008) showed that when the spectrum changes abruptly within a contiguous sound, a second primacy effect is observed on the second sound part. In a recent study, Fischenich et al (2020) reported that such a reoccurrence of the primacy effect is also obtained when a silent gap is inserted into the sound. Their data showed that after a gap of at least 350 ms, a significant primacy effect reoccurred on the second sound part.…”

“…Such forward-masking effects might result in higher intensity resolution for the first few temporal segments of a longer sound compared to later segments. In a loudness judgment task, this could induce a strategy of attending primarily to the beginning of the sound where the intensity resolution is higher (for an in-depth discussion see Fischenich et al, 2020). Because Zeng and Turner (1992) found that maskers with frequency components two to three octaves away from the signal frequency did not affect the intensity resolution for the signal, this explanation for the primacy effect would also predict frequencyspecific weights.…”

Previous work showed that the beginning of a sound is more important for the perception of loudness than later parts. When a short silent gap of sufficient duration is inserted into a sound, this primacy effect reoccurs in the second sound part after the gap. The present study investigates whether this temporal weighting occurs independently for different frequency bands. Sounds consisting of two bandpass noises were presented in four different conditions: (1) a simultaneous gap in both bands, (2) a gap in only the lower frequency band, (3) a gap in only the higher frequency band, or (4) no gap. In all conditions, the temporal loudness weights showed a primacy effect at sound onset. For the frequency bands without a gap, the temporal weights decreased gradually across time, regardless of whether the other frequency band did or did not contain a gap. When a frequency band contained a gap, the weight at the onset of this band after the gap was increased. This reoccurrence of the primacy effect following the gap was again largely independent of whether or not the other band contained a gap. Thus, the results indicate that the temporal loudness weights are frequency specific.

In everyday life, the auditory system often receives input from various sound sources at different positions in space more or less simultaneously. The present study investigates how listeners weight different spatial positions when judging the overall loudness of a spatially distributed sound field. Spatial weights were measured in two conditions. In both conditions, sounds were presented from five spatial positions: front, left, right, top and back, using five loudspeakers distributed spatially around the listener. In the first condition, bandpass noises were presented simultaneously on all five loudspeakers. The sounds emanating from the different loudspeakers did not overlap spectrally, to ensure that they could be differentiated from each other. In the second condition, a broadband noise was presented at each of the five spatial positions. In this condition, sounds from the five different positions were presented consecutively. In both conditions, listeners judged the overall loudness of the sound fields. Before measuring spatial weights, all sounds were equalised in loudness. Both conditions showed virtually identical spatial weights for all five spatial positions. Thus, the weight assigned to a specific sound source in judgments of the overall loudness of spatially distributed sound fields appears to be unaffected by the spatial position of the source.

Non-uniform temporal weights (TWs) are often reported regarding the perceptual evaluation of dynamic auditory and visual information, such as perceptual judgments of the overall intensity of time-varying stimuli. In particular, primacy effects, i.e., a stronger influence of early compared to later stimulus information on the perceptual decision, have been observed across a large number of studies. Yet, it is not clear whether these non-uniform patterns of TWs result from sensory or attentional processes that coincidentally produce similar time-courses, or whether they reflect the common signature of supra-modal and subject-specific decision-making processes. The present study addresses the hypothesis that TWs in loudness (perceived auditory intensity) and brightness (perceived visual intensity) judgments result from a common supramodal evidence-integration process. In Experiment 1, we compared TWs for loudness and brightness judgments in the same participants, with task difficulty matched individually. The observed average temporal weighting profiles differed substantially between the two modalities. In Experiment 2, we assessed the additional contribution of modality-specific sensory and attentional processes to the observed differences between TWs by measuring intensity resolution at different temporal positions in the auditory and visual stimuli. We observed a significantly different dependence of sensitivity on temporal position in the two modalities, but these sensitivity differences only partially accounted for the temporal weighting differences observed in Experiment 1. The collective findings indicate that the TWs observed for loudness and brightness judgments cannot be attributed to a supramodal evidence-integration process alone. Instead, our results suggest that both sensory and decision-making processes shape patterns of TWs.
