Paul of Venice and Realist Developments of Roger Swyneshed's Treatment of Semantic Paradoxes

In the 1330s Roger Swyneshed formulated a solution to semantic paradoxes based on the distinction between correspondence with reality and self-falsification as truth-making factors. Since Swyneshed states that some valid inferences are not truth-preserving, his view implies the question of the general definition of validity which he does not address explicitly. Logical works attributed to Paul of Venice (1369–1429) contain developments of Swyneshed's contextualist semantics substantially modified by the assumption that sentential meanings are objective propositional entities. The main goals of this paper are to show the correlations between the ontological and logical developments of Swyneshed's semantics in the works of Paul of Venice and to outline a context-sensitive formal semantics that could serve as a model of this family of semantic theories.     

The hippocampus: hub of brain network communication for memory

A complex brain network, centered on the hippocampus, supports episodic memories throughout their lifetimes. Classically, upon memory encoding during active behavior, hippocampal activity is dominated by theta oscillations (6-10Hz). During inactivity, hippocampal neurons burst synchronously, constituting sharp waves, which can propagate to other structures, theoretically supporting memory consolidation. This 'two-stage' model has been updated by new data from high-density electrophysiological recordings in animals that shed light on how information is encoded and exchanged between hippocampus, neocortex and subcortical structures such as the striatum. Cell assemblies (tightly related groups of cells) discharge together and synchronize across brain structures orchestrated by theta, sharp waves and slow oscillations, to encode information. This evolving dynamical schema is key to extending our understanding of memory processes.     

Not as gloomy as we thought: reassessing how the public understands probability of precipitation forecasts

Prior research on probability of precipitation (PoP) forecasts showed that many people wrongfully believe that PoP forecasts are derived from a percentage of time, a percentage of a region or the strength of agreement among forecasters. We posit that the wording of interpretation selection tasks matters, because different response options are associated with different metacognitive feelings. We hypothesised that the incorrect PoP interpretations are more often chosen by participants because they are more fluent than the correct PoP interpretation. We assessed the role of fluency in correctness perception (Study 1) and reassessed PoP interpretations with a more fluent correct interpretation (Study 2). Fluency perception was positively related with perception of correctness. Furthermore, participants selected the correct fluent interpretation more often than the correct disfluent one. We have drawn a more optimistic picture of people’s PoP forecasts understanding than that shown before and have discussed the methodological and applied implications.     

Skin-to-Skin contact (Kangaroo care) promotes self-regulation in premature infants: sleep-wake cyclicity, arousal modulation, and sustained exploration

The effect of mother-infant skin-to-skin contact (kangaroo care, or KC) on self-regulatory processes of premature infants was studied. Seventy-three infants who received KC were compared with 73 infants matched for birth weight, gestational age, medical risk, and family demographics. State organization was measured in 10-s epochs over 4 hr before KC and again at term. No differences between KC infants and controls were found before KC. At term, KC infants showed more mature state distribution and more organized sleep-wake cyclicity. At 3 months, KC infants had higher thresholds to negative emotionality and more efficient arousal modulation while attending to increasingly complex stimuli. At 6 months, longer duration of and shorter latencies to mother-infant shared attention and infant sustained exploration in a toy session were found for KC infants. The results underscore the importance of maternal body contact for infants' physiological, emotional, and cognitive regulatory capacities.     

Mental pain: a multidimensional operationalization and definition

An operationalization of mental pain is presented in three studies. The first study describes the operationalization of mental pain and the factor structure of the items produced by a content analysis of self-reports yielding a scale with nine factors: the experience of irreversibility, loss of control, narcissistic wounds, emotional flooding, freezing, estrangement, confusion, social distancing, and emptiness. Study 2 tested the relationship between mental pain and depression and anxiety in a normal population. Study 3 focused on the relationship between mental pain and coping. Mental pain is conceptualized as a perception of negative changes in the self and its functions that are accompanied by negative feelings. It is suggested that it can be meaningfully applied to the study of different mental states, life conditions, and transitions in life.     

The impact of pre-sleep arousal state and strategy to control unwanted thoughts on sleep quality

Objective: It has been questioned whether elevated pre-sleep cognitive arousal contributes to poor sleep or whether it is the use of maladaptive thought control strategies, used to manage this cognitive arousal, that are responsible. The study aimed to examine how these factors – cognitive arousal (with and without anxiety) and maladaptive thought control strategies contribute to perceived sleep quality (SQ). Design: 129 “healthy adults” (46 males, 83 females) were exposed to picture-stimuli eliciting either anxious cognitive arousal or non-anxious cognitive arousal at bedtime. The groups were then randomly split and briefed to use either a cognitive distraction or cognitive suppression thought control strategy or no instructions were given (controls). Subjective SQ was measured immediately on waking. Results: Induced anxious cognitive arousal was associated with lower SQ compared to non-anxious cognitive arousal. Analyses revealed a significant interaction between arousal and the strategies used to control unwanted thoughts on SQ. When experiencing anxious cognitive arousal, the strategy of distraction was associated with poorer sleep outcomes. Conclusion: The findings suggest that the efficacy of differing thought control strategies vary depending upon whether cognitive arousal elicits anxiety or not. With that in mind, clinical implications in terms of augmenting the treatment of insomnia are discussed.     

Cognitive Reflection Predicts Real‐Life Decision Outcomes,but Not Over and Above Personality and Decision‐Making Styles

The Cognitive Reflection Test (CRT), designed to assess the ability to inhibit intuition to process a problem analytically, predicts people's performance in many normative judgement and decision‐making tasks (e.g., Bayesian reasoning, conjunction fallacy and ratio bias). However, how the CRT predicts normative decision‐making performance is unclear, and little is known about the extent to which the CRT predicts real‐life decision outcomes. We investigate the role of the CRT in predicting real‐life decision outcomes and examine whether the CRT predicts real‐life decision outcomes after controlling for two related individual differences: the Big Five personality traits and decision‐making styles. Our results show that greater CRT scores predict positive real‐life decision outcomes measured by the Decision Outcome Inventory. However, the effect size was small, and the relationship became non‐significant after statistically controlling for personality and decision‐making styles. We discuss the limited predictive role of cognitive reflection in real‐life decision‐making outcomes, along with the roles of personality and decision‐making styles.

The polite wiggle‐room effect in charity donation decisions

We extend research on charity donations by exploring an everyday tactic for increasing compliance: asking politely. We consider three possible effects of politeness on charity donations: a positive effect, a negative effect, and a wiggle‐room effect where the perception of the request is adjusted to decline donating without feeling selfish. Results from six experiments systematically supported the polite wiggle‐room effect. In hypothetical donations contexts, indirect requests were judged more polite. In real donation contexts, though, indirect requests were not judged as more polite and had no consistent effect on donation decision. Rather, the decision to donate predicted the perceived politeness of the request, independently of its phrasing. Experiment 4 provided causal evidence that participants justified their donation decisions by adjusting their perception of the request. The polite wiggle‐room effect has important implications for organizations that seek to increase compliance while maintaining a positive image.
