ERPs studies of cognitive processing during sleep

In the last few decades, several works on cognitive processing during sleep have emerged. The study of cognitive processing with event related potentials (ERPs) during sleep is a topic of great interest, since ERPs allow the study of stimulation with passive paradigms (without conscious response or behavioural response), opening multiple research possibilities during different sleep phases. We review ERPs modulated by cognitive processes during sleep: N1, Mismatch Negativity (MMN), P2, P3, N400-like, N300-N550, among others. The review shows that there are different cognitive discriminations during sleep related to the frequency, intensity, duration, saliency, novelty, proportion of appearance, meaning, and even sentential integration of stimuli. The fascinating results of cognitive processing during sleep imply serious challenges for cognitive models. The studies of ERPs, together with techniques of neuroimaging, have demonstrated the existence of cognitive processing during sleep. A fundamental question to be considered is if these cognitive phenomena are similar to processing that occurs during wakefulness. Based on this question we discussed the existence of possible mechanisms associated with sleep, as well as the specific cognitive and neurophysiologic differences of wakefulness and sleep. Much knowledge is still required to even understand the conjunction of dramatic changes in cerebral dynamics and the occurrence of cognitive processes. We propose some insights based on ERPs research for further construction of theoretical models for integrating both cognitive processing and specific brain sleep dynamics.     

Disentangling the Mechanisms of Symbolic Number Processing in Adults’ Mathematics and Arithmetic Achievement

A growing body of research has shown that symbolic number processing relates to individual differences in mathematics. However, it remains unclear which mechanisms of symbolic number processing are crucial—accessing underlying magnitude representation of symbols (i.e., symbol‐magnitude associations), processing relative order of symbols (i.e., symbol‐symbol associations), or processing of symbols per se. To address this question, in this study adult participants performed a dots‐number word matching task—thought to be a measure of symbol‐magnitude associations (numerical magnitude processing)—a numeral‐ordering task that focuses on symbol‐symbol associations (numerical order processing), and a digit‐number word matching task targeting symbolic processing per se. Results showed that both numerical magnitude and order processing were uniquely related to arithmetic achievement, beyond the effects of domain‐general factors (intellectual ability, working memory, inhibitory control, and non‐numerical ordering). Importantly, results were different when a general measure of mathematics achievement was considered. Those mechanisms of symbolic number processing did not contribute to math achievement. Furthermore, a path analysis revealed that numerical magnitude and order processing might draw on a common mechanism. Each process explained a portion of the relation of the other with arithmetic (but not with a general measure of math achievement). These findings are consistent with the notion that adults’ arithmetic skills build upon symbol‐magnitude associations, and they highlight the effects that different math measures have in the study of numerical cognition.     

Seeing the language: a diagrammatic approach to natural discourse

The key idea behind the diagrammatic approach presented in the paper is that the sophisticated mechanisms of human visual construction also play an important role in natural languages. We propose a diagrammatic representation of English, giving examples, translation rules, and semantics. Special attention will be paid to anaphoric phenomena, in particular, the possibility of a uniform treatment of anaphoric pronouns.     

Image Induction and Social Influence: Explication and Initial Tests

Image induction posits that social influencers can manipulate a target's self-image to gain increased compliance. By preceding a request with a question that creates a salient self-image in a target, targets are more likely to behave consistently with that image by complying with the request. Three studies provide empirical tests of image induction. Results indicate that the addition of an image-inducing pretreatment question is associated with increased rates of compliance when compared to a control group. These findings held across two types of image induction manipulations (helpfulness, willingness to try new things), two types of behaviors (agreeing to complete a survey, agreeing to receive a free soft drink sample), and both face-to-face and written requests.     

Do human figure diagrams help alleged victims of sexual abuse provide elaborate and clear accounts of physical contact with alleged perpetrators?

The present study examined whether the use of human figure diagrams (HFDs) within a well‐structured interview was associated with more elaborate and clearer accounts about physical contact that had occurred in the course of an alleged abuse. The sample included investigative interviews of 88 children ranging from 4 to 13 years of age. Children were interviewed using the NICHD investigative interview protocol, and were then asked a series of questions in association with unclothed gender‐neutral outline diagrams of a human body. A new coding scheme was developed to examine the types and clarity of touch‐related information. Use of the HFDs was associated with reports of new touches not mentioned before and elaborations regarding the body parts reportedly touched. The HFDs especially helped clarify reports by the oldest rather than the youngest children. The clarity of children's accounts of touch was also greater when details were sought using recall prompts.

Phone follow up to families of COVID-19 patients who died at the hospital: families' grief reactions and clinical psychologists' roles

A proportion of persons affected by coronavirus disease-19 (COVID-19) die and do so in extraordinary circumstances. This can make grief management extremely challenging for families. The Clinical Psychology unit of an Italian hospital offered a bereavement follow-up call to such families. This study aimed to explore the families' experiences and needs collected during these calls, and the role that the psychologists played through the call. A total of 246 families were called over 3 months. Multiple qualitative methods included: (i) written reports of the calls with relatives of patients who died at the hospital for COVID-19; (ii) qualitative semi-structured interviews with psychologists involved in the calls; (iii) observation of psychologists' peer group discussions. A thematic analysis was conducted. Six themes emerged: without death rituals, solitary, unexpected, unfair, unsafe, coexisting with other stressors. Families' reactions were perceived by psychologists as close to a traumatic grief. Families' needs ranged from finding alternative rituals to giving meaning and expressing different emotions. The psychologists played both a social-institutional and a psychological-human role through the calls (e.g., they cured disrupted communication or validated feelings and choices). This study highlighted the potential of traumatic grief of families of COVID-19 victims, and provided indications for supporting them within the space of a short phone call.     

Social Identity Theory: a critical synthesis of its bases, evidence and controversies

The social identity theory (SIT) and the self-categorization theory have had considerable influence on contemporary Social Psychology, making notable contributions to our understanding of the social dimension of behaviour. In the present work, we summarise the bases of these theories and critically review the most controversial elements of SIT, exploring its limits and potential. As shown here, the literature offers a heterogeneous body of research that includes outstanding efforts of synthesis and integration, but also numerous fragmentary studies and decontextualized interpretations that have generated distorted views of group behaviour. Taking into account the multidimensional, contextually mediated, dynamic and functional nature of identitary processes, which clearly emerge in the most serious works in the field, there is obviously a need to review the epistemological and methodological tools currently employed, with a view to developing practices that allow the study of group phenomena in a manner more suited to their complexity.     

The cognitive locus of distraction by acoustic novelty in the cross-modal oddball task

Unexpected stimuli are often able to distract us away from a task at hand. The present study seeks to explore some of the mechanisms underpinning this phenomenon. Studies of involuntary attention capture using the oddball task have repeatedly shown that infrequent auditory changes in a series of otherwise repeating sounds trigger an automatic response to the novel or deviant stimulus. This attention capture has been shown to disrupt participants' behavioral performance in a primary task, even when distractors and targets are asynchronous and presented in distinct sensory modalities. This distraction effect is generally considered as a by-product of the capture of attention by the novel or deviant stimulus, but the exact cognitive locus of this effect and the interplay between attention capture and target processing has remained relatively ignored. The present study reports three behavioral experiments using a cross-modal oddball task to examine whether the distraction triggered by auditory novelty affects the processing of the target stimuli. Our results showed that variations in the demands placed on the visual analysis (Experiment 1) or categorical processing of the target (Experiment 2) did not impact on distraction. Instead, the cancellation of distraction by the presentation of an irrelevant visual stimulus presented immediately before the visual target (Experiment 3) suggested that distraction originated in the shifts of attention occurring between attention capture and the onset of the target processing. Possible accounts of these shifts are discussed.     

Beauty in the blink of an eye: The time course of aesthetic experiences

Under normal circumstances, perception runs very fast and seemingly automatic. In just a few ms, we go from sensory features to perceiving objects. This fast time course does not only apply to general perceptual aspects but also to what we call higher-level judgements. Inspired by the study on ‘very first impressions’ by Bar, Neta, and Linz (2006, Emotion, 6 , 269) the current research examined the speed and time course of three aspects of the aesthetic experience, namely beauty, specialness, and impressiveness. Participants were presented with 54 reproductions of paintings that covered a wide variety of artistic styles and contents. Presentation times were 10, 50, 100 and 500 ms in Experiment 1 and 20, 30 and 40 ms in Experiment 2. Our results not only show that consistent aesthetic judgements can be formed based on very brief glances of information, but that this speed of aesthetic impression formation also differs between different aesthetic judgements. Apparently, impressiveness judgements require longer exposure times than impressions of beauty or specialness. The results provide important evidence for our understanding of the time course of aesthetic experiences.
