How Early Does the Brain Distinguish between Regular Words, Irregular Words, and Pseudowords during the Reading Process? Evidence from Neurochronometric TMS.

Cognitive theories on reading propose that the characteristics of written stimuli determine how they are processed in the brain. However, whether the brain distinguishes between regular words, irregular words, and pseudowords already at an early stage of the reading process is still subject to debate. Here we used chronometric TMS to address this issue. During the first 140 msec of regular word, irregular word, and pseudoword reading, TMS was used to disrupt the function of the ventral occipitotemporal, posterior middle temporal, and supramarginal gyri, which are key areas involved in orthographic, semantic, and phonological processing, respectively. Early TMS stimulation delivered on posterior middle temporal and supramarginal gyri affected regular and irregular word, but not pseudoword, reading. In contrast, ventral occipitotemporal disruption affected both word and pseudoword reading. We thus found evidence for an early distinction between word and pseudoword processing in the semantic and phonological systems, but not in the orthographic system.

EMDR as Treatment Option for Conditions Other Than PTSD: A Systematic Review.

Eye Movement Desensitisation and Reprocessing (EMDR) is a treatment for post-traumatic stress disorder (PTSD). The technique is known to facilitate reprocessing of maladaptive memories that are thought to be central to this pathology. Here we investigate if EMDR therapy can be used in other conditions. We conducted a systematic literature search on PubMed, ScienceDirect, Scopus, and Web of Science. We searched for published empirical findings on EMDR, excluding those centred on trauma and PTSD, published up to 2020. The results were classified by psychiatric categories. Ninety articles met our research criteria. A positive effect was reported in numerous pathological situations, namely in addictions, somatoform disorders, sexual dysfunction, eating disorders, disorders of adult personality, mood disorders, reaction to severe stress, anxiety disorders, performance anxiety, Obsessive-Compulsive Disorder (OCD), pain, neurodegenerative disorders, mental disorders of childhood and adolescence, and sleep. Some studies reported that EMDR was successful in usually uncooperative (e.g., Dementia) or unproductive cases (e.g., aphasia). Moreover, in some severe medical conditions, when psychological distress was an obstacle, EMDR allowed the continuation of treatment-as-usual. Furthermore, the effects observed in non-pathological situations invite for translational research. Despite a generally positive outlook of EMDR as an alternative treatment option, more methodologically rigorous studies are needed. We discuss the advantages and limitations and possible implications for the hypothesised mechanisms of action.

Causal attribution in individuals with subclinical and clinical autism spectrum disorder: An fMRI study.

This neuroimaging study compares brain activation during causal attribution to three different attribution loci (i.e., self, another person, and situation) across a typical population without (N = 20) or with subclinical autism spectrum symptoms (N = 18) and a clinical population with autism spectrum disorder (ASD; N = 11). While they underwent fMRI, all participants read short sentences describing positive and negative behaviors and thoughts of another person directed toward the participant (i.e., "you"). Participants were then asked to attribute these behaviors to themselves, the other person, or the situation. Behavioral measures revealed self-serving attributions (i.e., attributing positive events to the self, while attributing negative events externally from the self) in all three participant groups. Neural measures revealed a great deal of shared activation across the three attribution loci and across the three participant groups in the temporo-parietal junction, the posterior superior sulcus, and the precuneus. Comparison between groups revealed more widespread activation in both subclinical and clinical ASD participants, which may be indicative of the extraneural resources these participants invest to compensate their impairments.

Registered Replication Report: Strack, Martin, & Stepper (1988).

According to the facial feedback hypothesis, people's affective responses can be influenced by their own facial expression (e.g., smiling, pouting), even when their expression did not result from their emotional experiences. For example, Strack, Martin, and Stepper (1988) instructed participants to rate the funniness of cartoons using a pen that they held in their mouth. In line with the facial feedback hypothesis, when participants held the pen with their teeth (inducing a "smile"), they rated the cartoons as funnier than when they held the pen with their lips (inducing a "pout"). This seminal study of the facial feedback hypothesis has not been replicated directly. This Registered Replication Report describes the results of 17 independent direct replications of Study 1 from Strack et al. (1988), all of which followed the same vetted protocol. A meta-analysis of these studies examined the difference in funniness ratings between the "smile" and "pout" conditions. The original Strack et al. (1988) study reported a rating difference of 0.82 units on a 10-point Likert scale. Our meta-analysis revealed a rating difference of 0.03 units with a 95% confidence interval ranging from -0.11 to 0.16.

The emergence of primary anoetic consciousness in episodic memory.

Based on an interdisciplinary perspective, we discuss how primary-process, anoetic forms of consciousness emerge into higher forms of awareness such as knowledge-based episodic knowing and self-aware forms of higher-order consciousness like autonoetic awareness. Anoetic consciousness is defined as the rudimentary state of affective, homeostatic, and sensory-perceptual mental experiences. It can be considered as the autonomic flow of primary-process phenomenal experiences that reflects a fundamental form of first-person "self-experience," a vastly underestimated primary form of phenomenal consciousness. We argue that this anoetic form of evolutionarily refined consciousness constitutes a critical antecedent that is foundational for all forms of knowledge acquisition via learning and memory, giving rise to a knowledge-based, or noetic, consciousness as well as higher forms of "awareness" or "knowing consciousness" that permits "time-travel" in the brain-mind. We summarize the conceptual advantages of such a multi-tiered neuroevolutionary approach to psychological issues, namely from genetically controlled primary (affective) and secondary (learning and memory), to higher tertiary (developmentally emergent) brain-mind processes, along with suggestions about how affective experiences become more cognitive and object-oriented, allowing the developmental creation of more subtle higher mental processes such as episodic memory which allows the possibility of autonoetic consciousness, namely looking forward and backward at one's life and its possibilities within the "mind's eye."
