Palm tree justice? The role of comparative law in the South Pacific

Emerging from a colonial past, Pacific island states have legal systems which are patchy and often incoherent. This article examines the role of judges in the field of family law and how, through creative use of comparative legal thinking, they contribute to the development of the law in countries where the state is slow to reform outdated and often inadequate legislation

Understanding attention to social information in adults with and without autism spectrum disorders

This thesis aims to further our understanding of social attention, and its manifestation in adults with autism spectrum disorders (ASD) and their typically-developed (TD) peers. Atypicalities in social attention have been proposed to play a crucial role in the development of autism. If social attention difficulties persist across the life-span, we would also expect them to impair ongoing social interactions in adolescents and adults with ASD. However, social attention in adulthood has been little examined. Instead, research tends to focus on more complex social cognitive difficulties, or to investigate attention to social stimuli presented in isolation. Our understanding of the role of social attention in autism is further inhibited by conflicting evidence on the influence of high-level input and low-level stimulus properties on selecting the focus of attention in TD individuals. The studies presented here tackle these issues by assessing social attention in adults using stimuli which: present social information in a realistic context; measure spontaneous attentional processes; and provide control over the low-level properties of stimuli. Three studies each employed a method newly applied to the study of social attention. These were: a free-description task that coded verbal accounts of social scenes; a social change detection task that recorded change detection speed and accuracy for alterations to social and non-social aspects of a person; and a preferential-looking task that presented social and non-social scenes side-by-side, while recording eye-movements. It was predicted that findings from each study would indicate a social attention bias in TD adults, while people with ASD would have either a weaker social attention bias or no bias at all. In contrast to predictions, these results showed that people with ASD spontaneously attend to social stimuli, as revealed by the social content of their verbal descriptions and their rapid and accurate detection of changes to eye-gaze direction. However, eye-tracking data in the preferential-looking task indicate that the social attention bias is subtly different in people with ASD, who show a reduced attentional priority for social information, and less persistence in looking at social stimuli over time, compared to TD participants. A series of cross-task analyses examining relationships between tasks indicated that a single social attention construct whichoperates across tasks and scenarios may not exist. These studies also emphasise the need to make distinctions between different types of social information and the idea of a hierarchy of social stimuli available in the real world is proposed. Taken together, the studies reported in this thesis provide new data indicating that social attentional difficulties found in children with autism do not continue in adulthood. Strong attentional preferences for social information, which override the influence of low-level stimulus properties, are found in both TD and ASD groups. The findings also contribute a new way of thinking about the construct of social attention, in particular indicating that different types of social information may interact with individual attentional preferences. These data are interpreted in the context of recent fmdings of perceptual atypicalities in people with ASD, which may interact with their social difficulties. The motion and multi-sensory properties of real-life social interaction may present specific processing difficulties for people with ASD. If so, the mild group differences found in our studies could translate into profound problems for people with ASD in the real world, and this is an area ripe for future research

Transdiagnostic research and the neurodiversity paradigm: commentary on the transdiagnostic revolution in neurodevelopmental disorders by Astle et al.

In their comprehensive and articulate paper on the Transdiagnostic Revolution in Neurodevelopmental Disorders, Astle, Holmes, Kievit and Gathercole (2022) ‘consider how well current classifications of neurodevelopmental disorders serve our understanding’. They examine the lack of mapping between clinical diagnoses such as ADHD or autism and research data at other levels of explanation, including genetics, neural structure and function, and cognition. The authors come to the conclusion that, if our goal is to explain variability and complexity, understand mechanisms and guide support decisions, ‘diagnostic taxonomies that classify individuals in terms of discrete categories are ill‐suited’. In this commentary, I explore alignment between their account of the transdiagnostic revolution and the neurodiversity paradigm and identify how transdiagnostic methods may promote neurodiversity‐affirmative research and practice

Social interest in high functioning adults with autism spectrum disorders.

Autism spectrum disorders (ASD) are principally characterized by impairments in social functioning. Experimental investigation often is conducted using methods measuring social attention, social cognition, and social communication. In this study, we instead measured interest in social information, making a distinction between basic-level person-centered social information such as physical attributes of people (“human” information) and high-level social information such as hypotheses about mental states, emotion, and relationships (“social” information). Based on content analysis of verbal descriptions of color images, 31 young adults (4 women), aged 17 to 25 years with ASD, and 35 typically developing young adults (8 women), aged 17 to 31 years, devoted similar proportions of their descriptions to human and social topics. Results are interpreted in the context of current calls for more ecologically valid methodology and in relation to other assessments of social processing in ASD

The Likely Economic Impact of Increasing Investment in Wind on the Island of Ireland. ESRI WP334. December 2009

This working paper supplements the report by Scott and Watson (2006) published by the Environmental Protection Agency. That report found that a weight-based charging regime introduced in West Cork (in the town of Clonakilty) in 2003 reduced the weight of waste put out by residents by 45 per cent. Results from recent studies are consistent with this finding, with reductions of 47 per cent and 43 per cent from weight-based charges found by O’Callaghan-Platt and Davies (2008) and Curtis et al (2009), respectively. The question still remains as to whether or not the charging reform was worthwhile. This paper addresses that question

Do people with autism spectrum disorders show normal selection for attention? Evidence from change blindness

People in the general population are typically very poor at detecting changes in pictures of complex scenes. The degree of this ‘change blindness’, however, varies with the content of the scene: when an object is semantically important or contextually inappropriate, people may be more effective at detecting changes. Two experiments investigated change blindness in people with autism, who are known from previous research to be efficient in detecting features yet poor at processing stimuli for meaning and context. The first experiment measured the effect of semantic information while the second investigated the role of context in directing attention. In each task, participants detected the dissimilarity between pairs of images. Both groups showed a main effect of image type in both experimental tasks, showing that their attention was directed to semantically meaningful and contextually inappropriate items. However, the autistic group also showed a greater difficulty detecting changes to semantically marginal items in the first experiment. Conclusions point to a normal selection of items for attention in people with autism spectrum disorders, although this may be combined with difficulty switching or disengaging attention
