Reward boosts working memory encoding over a brief temporal window

Selection mechanisms for WM are ordinarily studied by explicitly cueing a subset of memory items. However, we might also expect the reward associations of stimuli we encounter to modulate their probability of being represented in working memory (WM). Theoretical and computational models explicitly predict that reward value should determine which items will be gated into WM. For example, a model by Braver and colleagues in which phasic dopamine signalling gates WM updating predicts a temporally-specific but not item-specific reward-driven boost to encoding. In contrast, Hazy and colleagues invoke reinforcement learning in cortico-striatal loops and predict an item-wise reward-driven encoding bias. Furthermore, a body of prior work has demonstrated that reward-associated items can capture attention, and it has been shown that attentional capture biases WM encoding. We directly investigated the relationship between reward history and WM encoding. In our first experiment, we found an encoding benefit associated with reward-associated items, but the benefit generalized to all items in the memory array. In a second experiment this effect was shown to be highly temporally specific. We speculate that in real-world contexts in which the environment is sampled sequentially with saccades/shifts in attention, this mechanism could effectively mediate an item-wise encoding bias, because encoding boosts would occur when rewarded items were fixated.     

A Mixed-method Study of Individual,Couple, and Parental Functioning During the State-regulated COVID-19 Lockdown in Spain

During the recent COVID-19 outbreak in Spain, we explored the individual and relational well-being of people confined together with their partners and/or children during the first 3 weeks of state-regulated lockdown. Adults 18 years or older (N = 407) completed an online survey that included demographic, household, and employment information along with standardized measures of psychological distress (State-Trait Anxiety and Beck Depression) and relationship functioning—either the Dyadic Adjustment Scale if there were no children in the household or a Basic Family Relations Evaluation Questionnaire (CERFB) measuring conjugal, parental, and coparental functions. Qualitative analyses of responses to an open-ended question about perceived changes in couple or family dynamics during lockdown revealed nine specific themes comprising two overarching categories: relational improvement and deterioration. The overall prevalence of improvement themes (61.7%) exceeded deterioration themes (41.0%), with increased (re)connection and conflict atmosphere cited most often. Quantitative analyses found elevated levels of state anxiety but not trait anxiety or depression during lockdown. Consistent with the qualitative results, couples having no children at home reported high levels of dyadic adjustment, but with children present CERFB parental functioning exceeded conjugal functioning, a pattern sometimes associated with child triangulation into adult conflicts. Although correlates of psychological distress (e.g., unemployment, perceived economic risk) were relatively stable across subgroups, predictors of relationship functioning varied substantially with household/parental status (e.g., telecommuting and employment facilitated conjugal functioning only for couples with children).     

Self‐Images and “Perspicuous Representations”: Reflection,Philosophy, and the Glass Mirror

Reflection names the central activity of Western philosophical practice; the mirror and its attendant metaphors of reflection are omnipresent in the self‐image(s) of Western philosophy and in metaphilosophical reflection on reflection. But the physical experiences of being reflected by glass mirrors have been inadequately theorized contributors to those metaphors, and this has implications not only for the self‐image and the self (or selves) of philosophy but also for metaphilosophical practice. This article begins to rethink the metaphor of reflection anew. Paying attention to the history of the glass mirror in Europe reveals and challenges the modern emergence of clear ontological distinctions between disembodied subjects and the objects of their knowledge, and suggests a compelling terrain of metaphilosophical analysis. On the reading offered by the article, the inherent complexity of the relationship between selves and their mirror images, a complexity mediated by social location, historical situation, and particular projects, points to significant spaces of unknowing, of indeterminacy, and of ontological ambiguity.     

The name of the Piggle: Reconsidering Winnicott's classic case in light of some conversations with the adult ‘Gabrielle’

On the 40th anniversary of its publication, the author re‐reads Winnicott's The Piggle – a case of ‘on demand analysis’ with a child suffering from psychotic night terrors – in light of new information about the patient. Conversations between the author and ‘Gabrielle’ explore two areas not regarded as priorities by Winnicott: the transgenerational transmission of pathology/trauma, and the ways that language, in general – and given names, in particular – organize individual subjectivity. The question raised is to what degree Winnicott – who described the treatment as “psychoanalysis partagé [shared]” due to the parents’ involvement – thought of the pathology itself as ‘shared.’ The goal is not to supplant but to expand Winnicott's understanding of the case, borrowing insights from the work of Lacan and others.     

Basic‐Know And Super‐Know

Sometimes a proposition is ‘opaque’ to an agent: (s)he doesn't know it, but (s)he does know something about how coming to know it should affect his or her credence function. It is tempting to assume that a rational agent's credence function coheres in a certain way with his or her knowledge of these opaque propositions, and I call this the ‘Opaque Proposition Principle’. The principle is compelling but demonstrably false. I explain this incongruity by showing that the principle is ambiguous: the term ‘know’ as it appears in the principle can be interpreted in two different ways, as either basic‐know or super‐know. I use this distinction to construct a plausible version of the principle, and then to similarly construct plausible versions of the Reflection Principle and the Sure‐Thing Principle.     

The association between social isolation,loneliness and psychological problems in young adults: A study during the acute phase of COVID-19 in Italy

During the COVID-19 pandemic, governments had to impose social isolation measures to safeguard the citizens' health. However, this could have affected psychological problems. The aim of the present study was to investigate the psychological effects associated with social and emotional isolation during the acute phase of the COVID-19 in Italy. To this purpose, the degree of social isolation and loneliness and the presence of psychological problems (externalising and internalising) were investigated online in a sample of 395 young adults (18–30 years; 57% women). Results confirmed the relevant association between social isolation, loneliness and psychological problems, in both internalising and externalising dimensions. Particularly, loneliness showed the strongest association. Moreover, consistently with surveys conducted during the COVID-19-era, data highlighted that men were more vulnerable to social isolation and loneliness than women. These results underline the need for adequate interpersonal support during moments of isolation to prevent negative effects on psychological problems.
