Exploring the potential of Urban Leftover Spaces

<p>A city’s spatial environment emerges from the ongoing negotiation between the constructed environment, urban processes, and bodily experience. Many spaces do not represent a static notion but are continually challenged and reconstituted, including spaces that appear to be ‘leftover’. The ability to recognise leftover spaces in the urban context is an integral part of the urban redevelopment process, where structured and layered approaches become useful in understanding how to transform these spaces into places. Consequently, leftover spaces in the urban fabric can be seen both as having potential and as threatening. Researchers have pointed out the issues, conditions, and importance of the positive utilisation of leftover spaces. These spaces can be designed, transformed, and integrated into the main urban fabric to achieve environmental and social gains. Creative and flexible design should lead to psychologically healthy places by improving the image of a city from within. However, there is insufficient information available on how to go about designing such spaces. The revitalisation and aesthetic quality of leftover spaces could expand the dynamism of a city through strategic design interventions. This study explores how the visual perception of leftover spaces in Wellington City that influences both personal experiences and their potential usage could be enhanced. The research aims to investigate the potential of different types of urban leftover spaces, which could be used in a more effective way than they are present. The mixed methodology undertaken in this study seeks to inform planning initiatives by knowing what people feel about leftover spaces and their aspects that need improvement. This research, therefore, examines how such leftover spaces are defined and can be redesigned to become part of a built environment. The research thus consists of three studies starting with an initial visual preference study to understand human perceptions that could lead to better design solutions. The second study explored the differences in design preferences among participants coming from different fields of study, forming the main visual preference study. Visual preferences can guide behaviour and the emotional responses of different users in the redesign of such spaces and their essential attributes. Lastly, focus group discussions were held with built and non-built environment participants. To sum up, the results revealed that providing more vegetation is a critical design attribute for such spaces. The study contradicts theories that hold there are differences in the ways built and non-built environment experts perceive the environment.</p>

SUBJECTIVE EVALUATION OF VISUAL COMPLEXITY, CLARITY, AND PREFERENCE OF INDOOR ENVIRONMENTS

Visual comfort, task performance, and observers’ satisfaction is affected by the dynamic nature of visual perception and cognition. The perceived quality of the visual environment can be investigated in terms of visual complexity, visual clarity, and visual preference. This paper investigates the relationship between visual preference, visual clarity, visual complexity, colourfulness and the effect of spatial characteristics of images on the perceived quality of indoor environments. A visual experiment is conducted to assess the accuracy of image quality metrics in estimating the visual complexity, visual clarity, visual preference, and colourfulness of 50 images of indoor environments. Seven image quality assessment measures were used to estimate observers’ subjective evaluations. Results indicate that image colourfulness metric M correlates statistically significantly with visual preference and perception of colourfulness. Visual complexity correlated with five of the metrics. Future research will investigate wide range on images, including human-made and outdoor scenes.

Different serving shapes of cooked jasmine rice on a plate affect the consumer's visual preference

This research aimed to investigate how five different serving shapes of cooked jasmine rice (round, square, triangular, flower, and heart shapes) affected visual hedonic preference and consumer perception (n = 100). Cooked rice was placed on a plate without food, the heart, flower, and triangle serving shapes had higher artistic mean scores than the round shape. And cooked rice placed in the shape of a heart on a plate with food had a higher mean score on ‘liking in shape’ than round or square shapes. The findings of this study could be beneficial to food styling, presenting, and catering in the foodservice industry, resulting in increased sales, particularly in restaurants and hotels. Furthermore, for more successful food marketing and advertising, one can use the shapes of a heart as a serving shape for cooked jasmine rice box labels.

A Neural Network Model of Lexical-Semantic Competition During Spoken Word Recognition

Visual world studies show that upon hearing a word in a target-absent visual context containing related and unrelated items, toddlers and adults briefly direct their gaze toward phonologically related items, before shifting toward semantically and visually related ones. We present a neural network model that processes dynamic unfolding phonological representations of words and maps them to static internal lexical, semantic, and visual representations. The model, trained on representations derived from real corpora, simulates this early phonological over semantic/visual preference. Our results support the hypothesis that incremental unfolding of a spoken word is in itself sufficient to account for the transient preference for phonological competitors over both unrelated and semantically and visually related ones. Phonological representations mapped dynamically in a bottom-up fashion to semantic-visual representations capture the early phonological preference effects reported in visual world tasks. The semantic visual preference typically observed later in such a task does not require top-down feedback from a semantic or visual system.

“May I Grab Your Attention?”: An Investigation Into Infants' Visual Preferences for Handled Objects Using Lookit as an Online Platform for Data Collection

We examined the relation between 4- to 12-month-old infants' (N = 107) motor development and visual preference for handled or non-handled objects, using Lookit (lookit.mit.edu) as an online tool for data collection. Infants viewed eight pairs of objects, and their looking was recorded using their own webcam. Each pair contained one item with an easily graspable “handle-like” region and one without. Infants' duration of looking at each item was coded from the recordings, allowing us to evaluate their preference for the handled item. In addition, parents reported on their infants' motor behavior in the previous week. Overall, infants looked longer to handled items than non-handled items. Additionally, by examining the duration of infants' individual looks, we show that differences in infants' interest in the handled items varied both by infants' motor level and across the course of the 8-s trials. These findings confirm infant visual preferences can be successfully measured using Lookit and that motor development is related to infants' visual preferences for items with a graspable, handle-like region. The relative roles of age and motor development are discussed.

Abnormal visual attention to simple social stimuli in 4-month-old infants at high risk for Autism

Despite an increasing interest in detecting early signs of Autism Spectrum Disorders (ASD), the pathogenesis of the social impairments characterizing ASD is still largely unknown. Atypical visual attention to social stimuli is a potential early marker of the social and communicative deficits of ASD. Some authors hypothesized that such impairments are present from birth, leading to a decline in the subsequent typical functioning of the learning-mechanisms. Others suggested that these early deficits emerge during the transition from subcortically to cortically mediated mechanisms, happening around 2–3 months of age. The present study aimed to provide additional evidence on the origin of the early visual attention disturbance that seems to characterize infants at high risk (HR) for ASD. Four visual preference tasks were used to investigate social attention in 4-month-old HR, compared to low-risk (LR) infants of the same age. Visual attention differences between HR and LR infants emerged only for stimuli depicting a direct eye-gaze, compared to an adverted eye-gaze. Specifically, HR infants showed a significant visual preference for the direct eye-gaze stimulus compared to LR infants, which may indicate a delayed development of the visual preferences normally observed at birth in typically developing infants. No other differences were found between groups. Results are discussed in the light of the hypotheses on the origins of early social visual attention impairments in infants at risk for ASD.
