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

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 oneâs 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 oneâs own mental states (an aspect of metacognition) relies on the same mechanism as the ability to represent othersâ mental states (âmindreadingâ). 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 peopleâs 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 âanimationsâ 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
Spacings and pair correlations for finite Bernoulli convolutions
We consider finite Bernoulli convolutions with a parameter
supported on a discrete point set, generically of size . These sequences
are uniformly distributed with respect to the infinite Bernoulli convolution
measure , as tends to infinity. Numerical evidence suggests that for
a generic , the distribution of spacings between appropriately rescaled
points is Poissonian. We obtain some partial results in this direction; for
instance, we show that, on average, the pair correlations do not exhibit
attraction or repulsion in the limit. On the other hand, for certain algebraic
the behavior is totally different.Comment: 17 pages, 6 figure

Remembering the past and imagining the future in autism spectrum disorder
Recent research has revealed that episodic memory (remembering past experiences) and episodic future thinking (imagining future experiences) rely on the same underlying neuro-cognitive system. Consistent with this suggestion, individuals with autism spectrum disorder (ASD) have been shown to experience difficulties in both domains. In the present study, 18 adults with ASD and 18 typical adults performed sentence completion tasks assessing the ability to generate past and future events. Contrary to previous research findings, results demonstrated that adults with ASD performed at an equivalent level to typical adults when generating both past and future events; generating a higher number of specific events when recalling past (relative to simulating future) events, and a higher number of semantic associates when simulating future (relative to recalling past) events. Results are discussed with respect to methodological factors affecting task performance in ASD including the social nature of the research, the need to verbalise memories to the experimenter, and whether or not the specific memory request is explicit
Complexity Measures from Interaction Structures
We evaluate new complexity measures on the symbolic dynamics of coupled tent
maps and cellular automata. These measures quantify complexity in terms of
-th order statistical dependencies that cannot be reduced to interactions
between units. We demonstrate that these measures are able to identify
complex dynamical regimes.Comment: 11 pages, figures improved, minor changes to the tex

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 âselfâ task among people with ASD on balance, existing evidence suggests that individuals with ASD have atypical meâselves. 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: eventâbased and timeâbased
Voice Flows To And Around Leaders: Understanding When Units Are Helped Or Hurt By Employee Voice
In two studies, we develop and test theory about the relationship between speaking up, one type of organizational citizenship behavior, and unit performance by accounting for where employee voice is flowing. Results from a qualitative study of managers and professionals across a variety of industries suggest that voice to targets at different formal power levels (peers or superiors) and locations in the organization (inside or outside a focal unit) differs systematically in terms of its usefulness in generating actions to a unit's benefit on the issues raised and in the likely information value of the ideas expressed. We then theorize how distinct voice flows should be differentially related to unit performance based on these core characteristics and test our hypotheses using time-lagged field data from 801 employees and their managers in 93 units across nine North American credit unions. Results demonstrate that voice flows are positively related to a unit's effectiveness when they are targeted at the focal leader of that unitwho should be able to take actionwhether from that leader's own subordinates or those in other units, and negatively related to a unit's effectiveness when they are targeted at coworkers who have little power to effect change. Together, these studies provide a structural framework for studying the nature and impact of multiple voice flows, some along formal reporting lines and others that reflect the informal communication structure within organizations. This research demonstrates that understanding the potential performance benefits and costs of voice for leaders and their units requires attention to the structure and complexity of multiple voice flows rather than to an undifferentiated amount of voice.Business Administratio
Uniform generation in trace monoids
We consider the problem of random uniform generation of traces (the elements
of a free partially commutative monoid) in light of the uniform measure on the
boundary at infinity of the associated monoid. We obtain a product
decomposition of the uniform measure at infinity if the trace monoid has
several irreducible components-a case where other notions such as Parry
measures, are not defined. Random generation algorithms are then examined.Comment: Full version of the paper in MFCS 2015 with the same titl
