In a triangle completion task designed to assess path integration skill, younger and older adults performed similarly after being led, while blindfolded, along the route segments on foot, which provided both kinesthetic and vestibular information about the outbound path. In contrast, older adults' performance was impaired, relative to that of younger adults, after they were conveyed, while blindfolded, along the route segments in a wheelchair, which limited them principally to vestibular information. Correlational evidence suggested that cognitive resources were significant factors in accounting for age-related decline in path integration performance.
In two experiments, we investigated context effects on tempo judgments for familiar and unfamiliar songs performed by popular artists. In Experiment 1, participants made comparative tempo judgments to a remembered standard for song clips drawn from either a slow or a fast context, created by manipulating the tempos of the same songs. Although both familiar and unfamiliar songs showed significant shifts in their points of subjective equality toward the tempo context values, more-familiar songs showed significantly reduced contextual bias. In Experiment 2, tempo pleasantness ratings showed significant context effects in which the ordering of tempos on the pleasantness scale differed across contexts, with the most pleasant tempo shifting toward the contextual values, an assimilation of ideal points. Once again, these effects were significant but reduced for the more-familiar songs. The moderating effects of song familiarity support a weak version of the absolute-tempo hypothesis, in which long-term memory for tempo reduces but does not eliminate contextual effects. Thus, although both relative and absolute tempo information appear to be encoded in memory, the absolute representation may be subject to rapid revision by recently experienced tempo-altered versions of the same song.
Context effects on tempo and pleasantness judgments of different tempos were demonstrated in three experiments using Beatles songs. In Experiments 1 and 2, we explored how listening to versions of the same song that were played at different tempos affected tempo and pleasantness ratings. In both experiments, contrast effects were found on judgments of tempo, with target tempos rated faster when context tempos were slow than when they were fast. In both experiments, we also showed that the peak of the pleasantness rating function shifted toward the values of the context tempos, reflecting disordinal context effects on pleasantness relationships. Familiarity with the songs did not moderate these effects, and shifts in tempo ratings did not correlate with shifts in most pleasant target tempos when context was manipulated within subjects. In Experiment 3, we examined how manipulations of context tempos for one song affected judgments of the same song as compared with judgments of other more or less similar songs. For tempo ratings, contrast effects transferred to ratings of a similar song, but for pleasantness ratings, assimilative shifts of ideals were found only for the same song and not for similar songs. This pattern of results was supportive of independent bases for the two context effects.
Training metric accuracy in distance estimation skill for distances up to 300 m was done using three different feedback methods: Direct verbal feedback in the field, indirect visual feedback consisting of presentation of labelled markers in the field, and indirect visual feedback consisting of presentation of labelled markers in pictorial depictions of the field. Results from Experiment 1 showed that all three feedback methods resulted in rapid acquisition of skill in estimating perceived distance from a stationary viewpoint and that the skill transferred to a new field setting. Results from Experiment 2 replicated these results for the estimation of traversed distance along routes. These findings have important implications for the use of pictorial presentations, including virtual reality technology, to train generalizable spatial skills.
Studies of tempo perception suggest that exposure to a distribution of predominantly faster or slower versions of a song can shift one’s memory for the original tempo toward the contextual tempos. Three experiments were conducted to examine whether similar assimilation effects would occur when participants are asked to reproduce the tempo of a song from memory. In Experiments 1 and 2, participants listened to a tempo-altered version of a pop song prior to tapping out the original tempo from memory on each trial. Reproduced tempos assimilated toward the immediately preceding tempo, but there was no evidence of global assimilation toward the mean of the distribution of tempos. However, Experiment 2 demonstrated a partial dissociation between perception and production, with the same participants showing large assimilation effects derived from comparative judgments but not from tempo reproduction. In Experiment 3, participants listened to and then tapped out the beat of a tempo-altered version before reproducing the original from memory on each trial, which resulted in a global assimilation effect in reproduction. The results of these experiments highlight that contextual bias in memory for tempo depends on the match between the context and the task, with differential effects for perceptual and motor contexts.
