Linking metacognition and mindreading: Evidence from autism and dual-task investigations
Questions of how we know our own and other minds, and whether metacognition and mindreading rely on the same processes, are longstanding in psychology and philosophy. In Experiment 1, children/adolescents with autism (who tend to show attenuated mindreading) showed significantly lower accuracy on an explicit metacognition task than neurotypical children/adolescents, but not on an allegedly metacognitive implicit one. In Experiment 2, neurotypical adults completed these tasks in a single-task condition, or a dual-task condition that required concurrent completion of a secondary task that tapped mindreading. Metacognitive accuracy was significantly diminished by the dual-mindreading-task on the explicit task, but not the implicit task. In Experiment 3, we included additional dual-tasks to rule out the possibility that any secondary task (regardless of whether it required mindreading) would diminish metacognitive accuracy. Finally, in both experiments 1 and 2, metacognitive accuracy on the explicit task, but not the implicit task, was associated significantly with performance on a measure of mindreading ability. These results suggest that explicit metacognitive tasks (used frequently to measure metacognition in humans) share metarepresentational processing resources with mindreading, whereas implicit tasks (which are claimed by some comparative psychologists to measure metacognition in non-human animals) do not
Conservation status of New Zealand freshwater invertebrates, 2013
The conservation status of 644 freshwater invertebrate taxa, across five Phyla, 28 Orders and 75 Families, was assessed using the New Zealand Threat Classification System (NZTCS) criteria. Forty-six species were ranked Nationally Critical, 11 Nationally Endangered and 16 Nationally Vulnerable. One hundred and seventy-two taxa were listed as Data Deficient. A full list is presented, along with summaries and brief notes on the most important changes. This list replaces all previous NZTCS lists for freshwater invertebrates
Teacher Wellbeing in Remote Australian Communities
This paper reports on a project aimed at investigating teacher wellbeing in remote communities in Australia. It utilised a multiple case study methodology to investigate the lived experiences of remote Australian teachers, particularly how remote teachers simultaneously manage the wellbeing and academic needs of their students. Findings show how the challenges of working in remote places impact teacher wellbeing and provides six practical recommendations about how to better support remote teachers. There is a present need to develop a framework of remote teachers thriving, so systems and communities are not over-reliant upon teachersā individual resilience in hard-to-staff places

Metacognition, Metamemory, and Mindreading in High-Functioning Adults With Autism Spectrum Disorder
Objectives: Metacognition refers to cognition about cognition, and encompasses both knowledge of cognitive processes and the ability to monitor and control oneās own cognitions. The current study aimed to establish whether metacognition is impaired in autism spectrum disorder (ASD). According to some theories, the ability to represent oneās own mental states (an aspect of metacognition) relies on the same mechanism as the ability to represent othersā mental states (āmindreadingā). Given numerous studies have shown mindreading is impaired in ASD, there is good reason to predict concurrent impairments in metacognition. Metacognition is most commonly explored in the context of memory, often by assessing peopleās ability to monitor their memory processes. The current study addressed the question of whether people with ASD have difficulty monitoring the contents of their memory (alongside impaired mindreading).
Method: Eighteen intellectually high-functioning adults with ASD and 18 IQ- and age-matched neurotypical adults participated. Metamemory monitoring ability and mindreading ability were assessed using a feeling-of-knowing task and the āanimationsā task, respectively. Participants also completed a self-report measure of metacognitive ability.
Results: In addition to showing impaired mindreading, participants with ASD made significantly less accurate feeling-of-knowing judgements than neurotypical adults, suggesting that metamemory monitoring (an aspect of metacognition) was impaired. Conversely, participants with ASD self-reported superior metacognitive abilities compared to those reported by neurotypical participants.
Conclusion: This study provides evidence that individuals with ASD have metamemory monitoring impairments. The theoretical and practical implications of these findings for our current understanding of metacognition in ASD and typical development are discussed

The self in autism and its relation to memory
This chapter begins with some definitions of memory and the self and continues to explain their relation on the psychological level along with their facets. It considers the relevance of these theories to autism spectrum disorder (ASD). The chapter provides a critical review of relevant research on the self in autism, followed by some hypotheses concerning how diminished sense of self might predict and explain the unique memory profile in the ASD population. Although there are a considerable number of studies showing typical performance on some types of āselfā task among people with ASD on balance, existing evidence suggests that individuals with ASD have atypical meāselves. There is a considerable amount of evidence to suggest that individuals with ASD have impaired episodic memory. Strikingly, the study of prospective memory in ASD is an emergent research field with a handful of studies published to date. Two forms of prospective memory are commonly distinguished: eventābased and timeābased
Rock Response in a 12-M Tunnel through a Zone of Low Strength
At the Rocky Mountain Pumped Storage Project a 12 meter diameter power tunnel was excavated through sedimentary rock for 760 meters. Approximately 10% of this tunnel was through Pennington shale that is described as a dark gray massive organic shale. This paper will describe the methods of testing .and rock characterization, the results of instrumentation and monitoring, and the post-construction testing program for the excavation, and conclude with a discussion of the observed rock response in relation to the measured strength and deformation properties. This particular zone of the tunnel required the addition of longer rockbolts, and a discussion of that supplemental rock reinforcement will be included
From dot to ring: the role of friction on the deposition pattern of a drying colloidal suspension droplet
The deposition of particles on a substrate by drying a colloidal suspension
droplet is at the core of applications ranging from traditional printing on
paper to printable electronics or photovoltaic devices. The self-pinning
induced by the accumulation of particles at the contact line plays an important
role in the formation of the deposition. In this paper, we investigate both
numerically and theoretically, the effect of friction between the particles and
the substrate on the deposition pattern. Without friction, the contact line
shows a stick-slip behaviour and a dot-like deposit is left after the droplet
is evaporated. By increasing the friction force, we observe a transition from a
dot-like to a ring-like deposit. We propose a theoretical model to predict the
effective radius of the particle deposition as a function of the friction
force. Our theoretical model predicts a critical friction force when the
self-pinning happens and the effective radius of deposit increases with
increasing friction force, confirmed by our simulation results. Our results can
find implications for developing active control strategies for the deposition
of drying droplets.Comment: 11 pages, 10 figure
