The Relationship between Viewing Area Size and Visitor Behavior in an Immersive Asian Elephant Exhibit

ABSTRACT

Immersive exhibits are increasingly popular in zoos, being seen as benefiting both animals and visitors. Multiple, discreet viewing areas are one of the key features of immersive zoo exhibits. Small, discreet viewing areas afford the visitor a very personal and intimate experience and may promote an affiliative response between the visitor and the animals on display, thus enhancing the immersive experience. This investigation sought to determine the effect of these viewing areas on visitor behavior, particularly in exhibits where the same animals could be viewed from different-sized viewing areas. This study in the Elephants of the Asian Forest exhibit at Chester Zoo, used unobtrusive visitor tracking to investigate how visitors behave at the exhibit's different-sized viewing areas. The results show that visitors are much more likely to stop, and stay for longer, at the largest viewing areas. Furthermore, there appears to be a proportional increase in visitor interest with increasing viewing area size. These findings have implications for zoo exhibit designers, particularly on the order in which viewing areas should be positioned.     

Tigers and teapots: what does it mean to be alive?

The Symposium entitled 'Conceptual Knowledge: Developmental, Biological, Functional and Computational Accounts' was held at the British Academy, London, UK on 24-26 June 2002. It was funded by the British Academy with support from the Novartis Foundation, and organized by Lorraine Tyler (University of Cambridge, UK) and Tim Shallice (University College London, UK).     

Olfactory working memory: exploring the differences in n-back memory for high and low verbalisable odorants

ABSTRACT

We describe four experiments each examining n-back performance for high and low verbalisable odorants. Participants were presented with a sequence of odorants and were required to state if the current odorant was the same or different to the odorant presented two items earlier. Experiment 1 reported superior performance for high, relative to low, verbalisable odorants and was evident despite above-chance memory performance for the low verbalisable odorants. Experiment 2 showed that such superiority persisted with a concurrent articulation condition, suggesting that the memory benefit was not a consequence of verbal recording and rehearsal. Experiment 3 employed metacognitive judgments and showed that correct 2-back responses for high verbalisable odorants received more recollection responses compared to low verbalisable odorants. Experiment 4 compared n-back performance across different stimulus types and showed that, for high verbalisable odorants, performance correlated with both letters and abstract shapes, but such correlations were absent for low verbalisable odorants. Taken together, these findings show differences in n-back performance between high and low verbalisable odorants, and show that high verbalisable odorants exhibit performance similarities with both verbal and visual stimuli. We further argue that n-back performance for low verbalisable odorants operates differently to that of high verbalisable odorants.     

Investigating semantic memory impairments: The contribution of semantic priming

Abstract

The semantic priming task is a valuable tool in the investigation of semantic memory impairments in patients with acquired disorders of language. This is because priming performance reflects automatic or implicit access to semantic information, unlike most other tests of semantic knowledge, which rely on explicit, voluntary access. Priming results are important for two main reasons: First, normal priming results may be observed in patients who perform poorly on other semantic memory tests, enabling us to distinguish between loss of, or damage to, information in semantic memory, and voluntary access to that information. Second, we can investigate the detailed pattern of loss and preservation of different types of semantic information, by charting the priming effects for different kinds of words, and different kinds of semantic relations between primes and targets.

We discuss the use of the priming task in this context, and address some of the theoretical and methodological criticisms that have been raised in connection with use of the priming task to address these issues. We then describe two recent studies in which we have employed semantic priming tasks, along with other more traditional methods, to investigate specific questions about the semantic memory deficits of three patients.     

Type A Behavior and Marital Dissatisfaction: Disentangling the Effects of Achievement Striving and Impatience-Irritability

Previous research has documented an association between overall Type A behavior and marital dissatisfaction. The present study examines the nature of this relationship when a two dimensional approach to Type A behavior is adopted, and impatience-irritability and achievement striving are assessed separately. Subjects were 134 medical practitioners and specialists and their wives in South Africa. As predicted, husbands' impatience-irritability was associated with their own and their wives' marital dissatisfaction. However, neither their achievement striving nor global Type A behavior correlated with their own or their wives' marital dissatisfaction. The results are discussed in terms of the need for isolating the specific component of Type A behavior that is associated with marital dissatisfaction.     

Distinctiveness and correlation in conceptual structure: behavioral and computational studies

Patients with category-specific deficits have motivated a range of hypotheses about the structure of the conceptual system. One class of models claims that apparent category dissociations emerge from the internal structure of concepts rather than fractionation of the system into separate substores. This account claims that distinctive properties of concepts in the living domain are vulnerable because of their weak correlation with other features. Given the assumption that mutual activation among correlated properties produces faster activation in the normal system, the authors predicted a disadvantage for the distinctive features of living things for unimpaired adults. Results of a speeded feature verification study supported this prediction, as did a computational simulation in which networks mapped from orthography to semantics.
