This work examines the effect of participants' gender and handedness on the perception of short intervals of time. The time estimation task consisted of an empty production procedure with forty trials at each of four intervals of one, three, seven, and twenty seconds. The four target intervals represent a natural logarithmic progression and a series that bracket important temporal thresholds. The order of presentation of those intervals was randomized across participants but yoked across the...
Show moreThis work examines the effect of participants' gender and handedness on the perception of short intervals of time. The time estimation task consisted of an empty production procedure with forty trials at each of four intervals of one, three, seven, and twenty seconds. The four target intervals represent a natural logarithmic progression and a series that bracket important temporal thresholds. The order of presentation of those intervals was randomized across participants but yoked across the sexes in each of the respective dominant hand groups. The two between-subject factors, with two levels each, were sex and handedness. Participants produced forty estimates at each of the required intervals, which was the first within-subject factor, estimated interval being the other. T-tests were conducted on the dependent measures, the time estimates in terms of their variability and their central tendency with respect to the target duration. If handedness plays a significant role in timing, this may indicate differences between hemispheric functioning as a possible causal mechanism. If there is cerebral asymmetry in time perception, namely if one hemisphere is more competent regarding time perception, accuracy in judging duration should be higher for the contralateral hand. The results of the present study indicated that there are no significant differences in performance between right-handed and left-handed participants, or between male and female participants, in the estimation of short intervals of time.

With the increasing attendance across amusement and theme parks worldwide, it is not surprising that minimizing the impact of large crowds and long attraction waits on the guests' experience has received much focus by park operators in recent years. Although effective in the short term, attempting to eliminate or reduce wait times by simply increasing capacity cannot be sustained long term. A recent trend in amusement park design is to theme the queue with interactive elements to engage...
Show moreWith the increasing attendance across amusement and theme parks worldwide, it is not surprising that minimizing the impact of large crowds and long attraction waits on the guests' experience has received much focus by park operators in recent years. Although effective in the short term, attempting to eliminate or reduce wait times by simply increasing capacity cannot be sustained long term. A recent trend in amusement park design is to theme the queue with interactive elements to engage guests and occupy their wait time with the intent of making the wait queue part of the attraction itself. Much of the research on the topic of waiting in line focuses on improving the customers' experience while waiting by altering the wait queue. Very little research to date empirically tests the impact that queue characteristics have on a customers' perceived wait duration with the research pool void of any applications to an interactive amusement park queue. This dissertation study tested five hypotheses to determine how playing an interactive math skills game while waiting to ride a virtual roller coaster affected the participants' perceived wait duration. The first hypothesis tested if the participants' perceived wait time decreased as the mental workload of the game increased. The results did not find that this effect of mental workload on perception of time was significant. The second hypothesis tested whether participants who experience higher levels of game immersion estimate perceive wait time to be lower. The results indicated that this effect of game immersion on perceived wait time was significant. The third hypothesis tested whether participants' experience higher levels of game immersion when the perceived mental workload of the math skills game was higher. This effect of mental workload on immersion was found to be significant.Hypothesis 4 tested whether the participants' perceived wait time was indirectly effected by the mental workload of the math skills through immersion. This indirect effect was found to be significant and the results support complete mediation by immersion because the direct effect was not significant with the indirect effect in the model. Hypothesis tested whether the mediated effect of mental workload on time perception via game immersion was moderated by participants' levels of sensation seeking and extraversion. Individual differences of extraversion and sensation seeking were not found to moderate the indirect effect.This study demonstrates that research in the area of time perception can be applied to amusement and theme park queue design. Furthermore, it shows the importance of providing guests with an immersive queue experience to positively impact their perception of wait time, the number one complaint of many amusement and theme park visitors. Future research in this field should examine the individual elements of the queue environment to determine the optimal design to increase the level of immersion for park guests.

- CATEGORICAL PERCEPTION OF STOP CONSONANTS IN CHILDREN WITH AUTISM.
- Creator

Bourdeau, Laura, Ryalls, Jack, University of Central Florida
- Abstract / Description
-
The purpose of this study is to determine whether children with autism recognize the same perceptual voicing boundaries of stop consonants as normally developing children of the same age group. This was explored using three groups of participants: ten children with autism between the ages of 8-14, five typically developing children between the ages of 8-14, and five typically developing seven-year-old children. Children in all groups listened to initial stop consonant syllables with voicing...
Show moreThe purpose of this study is to determine whether children with autism recognize the same perceptual voicing boundaries of stop consonants as normally developing children of the same age group. This was explored using three groups of participants: ten children with autism between the ages of 8-14, five typically developing children between the ages of 8-14, and five typically developing seven-year-old children. Children in all groups listened to initial stop consonant syllables with voicing contrasts, with voiced and voiceless cognates presented. The initial consonants were altered along a voice onset time continuum within the typically perceived boundaries of each consonant. Participants were instructed to select the box containing the letter of the initial consonant they perceive when they hear each syllable. Results revealed greater difference between the responses of the children with autism when compared with the older control group, than when compared with the younger children. The responses of the children with autism were more similar to those of the children in the second control group. This could be indicative of a delay in the children with autism of perception of the categorical boundaries along the dimension of voice onset time compared to typical children‟s perception of these consonants.

In order to be included, each study needed to examine the relationship between the use of an ego-centric perspective and various dimensions of performance (i.e., identification, localization, navigation, and mission completion time).

Show moreMeta-analysis was used to investigate the relationship between visuo-spatial ability and performance in remote environments. In order to be included, each study needed to examine the relationship between the use of an ego-centric perspective and various dimensions of performance (i.e., identification, localization, navigation, and mission completion time). The moderator analysis investigated relationships involving: (a) visuo-spatial construct with an emphasis on Carroll's (1993) visualization (VZ) factor; (b) performance outcome (i.e., identification, localization, navigation, and mission completion time); (c) autonomy to support mission performance; (d) task type (i.e., navigation vs. reconnaissance); and (e) experimental testbed (i.e., physical vs. virtual environments). The process of searching and screening for published and unpublished analyses identified 81 works of interest that were found to represent 50 unique datasets. 518 effects were extracted from these datasets for analyses.Analyses of aggregated effects (Hunter (&) Schmidt, 2004) found that visuo-spatial abilities were significantly associated with each construct, such that effect sizes ranged from weak (r = .235) to moderately strong (r = .371). For meta-regression (Borenstein, Hedges, Figgins, (&) Rothstein, 2009; Kalaian (&) Raudenbush, 1996; Tabachnick (&) Fidell, 2007), moderation by visuo-spatial construct (i.e., focusing on visualization) was consistently supported for all outcomes. For at least one of the outcomes, support was found for moderation by test, the reliability coefficient of a test, autonomy (i.e. to support identification, localization, and navigation), testbed (i.e., physical vs. virtual environment), intended domain of application, and gender. These findings illustrate that majority of what researchers refer to as (")spatial ability(") actually uses measures that load onto Carroll's (1993) visualization (VZ) factor. The associations between this predictor and all performance outcomes were significant, but the significant variation across moderators highlight important issues for the design of unmanned systems and the external validity of findings across domains. For example, higher levels of autonomy for supporting navigation decreased the association between visualization (VZ) and performance. In contrast, higher levels of autonomy for supporting identification and localization increased the association between visualization (VZ) and performance. Furthermore, moderation by testbed, intended domain of application, and gender challenged the degree to which findings can be expected to generalize across domains and sets of participants.
