TL;DR: A natural history of children's developing self-awareness is proposed as well as a model of adult self- awareness that is informed by the dynamic of early development.

TL;DR: It is proposed that transient hypofrontality is the unifying feature of all altered states and that the phenomenological uniqueness of each state is the result of the differential viability of various frontal circuits.

TL;DR: The continuity hypothesis in its present general form is not valid and should be elaborated and tested in a more specific way and include factors which modulate the incorporation rate of waking-life experiences into dreams.

TL;DR: It is suggested that within this shared neural network the inferior parietal cortex and the prefrontal cortex in the right hemisphere play a special role in the essential ability to distinguish the self from others, and in the way the self represents the other.

TL;DR: An experiment in which normal subjects judged the perceived time of either intentional actions, involuntary movements, or subsequent effects (auditory tones) of these found that the subject's intention to produce the auditory tone produced an intentional binding between the perceived times of thesubject's action and the tone.

TL;DR: The results of all three experiments suggested that experiencing TUT during study had a measurable effect on subsequent retrieval, and TUT was associated with increased frequency of false alarms at retrieval and no advantage to retrieval based on recollection.

TL;DR: The reported experiments challenge and support an independent, parallel processing model, which predicts that procedural and declarative knowledge can be acquired separately and that the former does not depend on the availability of working memory while the latter does.

TL;DR: This tutorial review examines the interacting roles of these five systems in perception, working memory, attention, long-term memory, motor control, and thinking.

TL;DR: This study reports a modified replication of Woodward (1999) showing that when a salient action-effect is presented, even young infants can attribute a goal to an unfamiliar manual action.

TL;DR: It is argued that the brain, viewed as a representational system aimed at interpreting the authors' world, possesses an ontology too, which creates primitives and makes existence assumptions and decomposes target space in a way that exhibits a certain invariance, which in turn is functionally significant.

TL;DR: Three experiments were conducted on healthy participants using a categorical stimulus organization to contrast distributed and encapsulated views of cognition and showed that despite the increased difficulty of the alphabetical verbal fluency task fewer TUTs were produced during category fluency condition.

TL;DR: Interestingly, these experiments show converging evidence for a recruitment of medial cortical and parietal regions during taking a first-person-perspective, even when operating on different degrees of complexity, lending support for the speculative hypothesis, that there exist a neural signature for human self-consciousness that is recruited independent from the degree of representational complexity to be performed.

TL;DR: The results first argue in favour of a dominant role of proprioception in action recognition, but they also stress the possible role of central signals.

TL;DR: It is argued, that self-consciousness is a valid construct and can be studied with the instruments of cognitive and neuroscience, and on pathological aspects of self-agency.

TL;DR: Recent evidence suggesting that action (procedural) knowledge also forms part of a person's identity, an action identity, so to speak is reviewed.

TL;DR: The results showed that the observation of the model had an impact on the infants' exploration behavior from 12 months, but not earlier, and that the specific relations between observed actions and effects were acquired by 15 months.

TL;DR: An fMRI experiment was conducted that compared brain activation after an abrupt mismatch between one's own movement and its visual consequences with a sudden mismatch between someone else's visually perceived hand movement.

TL;DR: The view that Stroop interference is neither robust nor inevitable is strengthened and the hypothesis that posthypnotic suggestion may exert a top-down influence on neural processing is supported.

TL;DR: Psychophysical and neuroimaging studies that have investigated how the authors recognise the consequences of their own actions, and why patients with delusions of control confuse self-produced and externally produced actions and sensations are reviewed.

TL;DR: In schizophrenia, the ability of sensory input to modulate self-organisation of thalamocortical gamma activity may be generally reduced and attentional mechanisms alone may determine the content of perception and hallucinations may arise.

TL;DR: It is shown that, in contrast to other reports on the salience of negative stimuli, happy faces appear more salient than sad faces when presented outside awareness.

TL;DR: Neuroimaging evidence in humans for an additional role of the hippocampal formation in nonconscious memory is reported for the first time, and clues are provided to an analogousrole of the hippocampus in conscious and non Conscious memory.

TL;DR: Two new experiments are presented which investigate the role of action effects in the awareness of self- and other-generated actions by means of measuring the estimated onset time and show that the presence ofaction effects is necessary for the similarity of awareness ofSelf- andOther- generated actions.

TL;DR: There was a weak trend for suppression to enhance reported intentionality for a repetition of the action carried out after suppression instructions had been discontinued.

TL;DR: In this article, the authors examined source attributions based on positive versus negative valence in four experiments and found that test biases to attribute positive statements to positive sources and negative statements to negative sources were strongly present.

TL;DR: Raz, Shapiro, Fan, and Posner (2002) provided a compelling demonstration of enhanced attentional control under post-hypnotic suggestion by eliminating Stroop interference in high suggestibility participants but did not alter interference in low suggestibility Participants.

TL;DR: It is argued that it may be possible to map the concept 'self' onto the regularities referred to in the event-control model, not in order to reify 'the self' as a causal mechanism, but to demonstrate its status as a useful concept that refers to regularities that are part of the natural order.

TL;DR: Simulations using a simple neural network model of two artificial grammar learning experiments reported by that dissociated conscious and unconscious influences on classification demonstrate that opposition logic is insufficient to distinguish between single- and multiple-system models.

TL;DR: The tentative answer to the guiding question is that children become consciously aware between 12 and 15 months (+/-3 months).
