Directed forgetting of autobiographical memory in mild Alzheimer's disease

Using the autobiographical directed forgetting method (Barnier et al., 2007), the present paper addressed the intentional inhibitory processes of episodic and semantic autobiographical memory in Alzheimer's disease (AD). Mild AD patients and healthy elderly people were instructed to either forget or to continue remembering previously generated autobiographical events. In a later recall test they were asked to reconstruct the early-generated memories regardless of the forget/remember instruction. Autobiographical reconstruction was further distributed into episodic and semantic memories. Results showed no forget instruction effect on episodic or semantic autobiographical recall with AD patients, whereas healthy elderly people were able to inhibit only episodic autobiographical memories. The findings suggest an impairment of the intentional inhibitory processes in autobiographical memory with AD and a relative preservation of these mechanisms with normal ageing. They also demonstrate an earlier decline in the intentional inhibitory processes compared to the autobiographical deterioration in AD.     

On the completeness of a certain system of arithmetic of whole numbers in which addition occurs as the only operation

Presburger's essay on the completeness and decidability of arithmetic with integer addition but without multiplication is a milestone in the history of mathematical logic and formal metatheory. The proof is constructive, using Tarski-style quantifier elimination and a four-part recursive comprehension principle for axiomatic consequence characterization. Presburger's proof for the completeness of first order arithmetic with identity and addition but without multiplication, in light of the restrictive formal metatheorems of Gödel, Church, and Rosser, takes the foundations of arithmetic in mathematical logic to the limits of completeness and decidability.     

Voice and Culture: A Prospect Theory Approach

The present study examines the congruence of individuals' minimum preferred amounts of voice with the prospect theory value function across nine countries. Accounting for previously ignored minimum preferred amounts of voice and actual voice amounts integral to testing the steepness of gain and loss functions explicated in prospect theory, we use curve fitting to show that ratings of procedural justice fit prospect theory's value function specifically. Further, we investigate the form of this function across nine countries that range in power distance. Results suggest that the form of the value function is congruent with prospect theory, showing an S‐shaped curve that is steeper in the loss than in the gain domain. Further, this pattern is similar across countries. Theoretical and practical implications of these results for both decision making and organizational justice are discussed.

Flashbulb memories of the Paris attacks

Flashbulb memories are vivid autobiographical memories of the circumstances where an individual first learns about emotionally significant public events. Our paper assesses whether these memories were triggered by the attacks of Friday 13 November 2015 in Paris. Two hundred and ninety‐one participants answered a web‐based questionnaire that assessed their memory of the circumstances in which they first learned of the attacks. The questionnaire also assessed vividness, rehearsal, emotion, surprise and novelty. The results showed substantial and vivid recall of the context in which the participants first learned of the event. This recall was associated with fair rehearsal, negative emotional valence, surprise, and novelty. Regression analysis showed that the flashbulb recall was predicted by negative emotion. Negative emotion seems to play a key role in the formation of flashbulb memories, at least those associated with the Paris attacks.     

Positive experiences in the parent–child relationship during the COVID-19 lockdown in Poland: The role of emotion regulation,empathy, parenting self-efficacy,and social support

Despite the impact of the COVID-19 outbreak being largely negative on parents and children, for some families, lockdown could also bring about some positive effects, for example, increased emotional closeness, and more time for joint activity. The aim of the current study was to investigate cross-sectionally the most important correlates of the positive experiences in the parent–child relationship among Polish mothers and fathers during the lockdown in the initial phase of the COVID-19 outbreak. In May 2020, 228 mothers and 231 fathers completed the Brief version of the Empathic Sensitivity Questionnaire, Difficulties in Emotion Regulation Scale Short Form, Social Support Scale, Parenting Self-Agency Measure, and Scale of Positive Experiences in Parent–Child Relationship during the COVID-19 lockdown. Our results showed that parenting self-efficacy and social support were the strongest correlates of positive experiences in the parent–child relationship in both mothers and fathers during the lockdown. Perspective-taking was positively related to the positive experiences in mothers, whereas personal distress was positively associated with the positive experiences in the parent–child relationship in fathers. Our results point to factors of potential importance in designing preventive and therapeutic interventions for mothers and fathers to enhance positive experiences in the parent–child relationship during the pandemic.     

Measurement Invariance of Personal Well-Being Index (PWI-8) Across 26 Countries

This report examines the measurement invariance of the Personal Well-being Index with 8 items (PWI-8). University students (N = 5731) from 26 countries completed the measure either through paper and pencil or electronic mode. We examined uni-dimensional structure of PWI and performed a Multi-group CFA to assess the measurement invariance across the 26 countries, using conventional approach and the alignment procedure. The findings provide evidence of configural and partial metric invariance, as well as partial scalar invariance across samples. The findings suggest that PWI-8 can be used to examine correlates of life satisfaction across all included countries, however it is impossible to compare raw scores across countries.     

The Sense of Quality of Life and Religious Strategies of Coping with Stress in Prison Inmates

The aim of the presented research was to analyze differences in religious strategies of coping with stress in a group of prison inmates characterized by different levels of the sense of quality of life—general, psychophysical, psychosocial, personal, and metaphysical. The participants were 390 males, aged 19–68 years, serving sentences in prisons in Poland. The measures used were the Sense of Quality of Life Questionnaire by M. Stra?-Romanowska and K. I. Pargament’s RCOPE Questionnaire. As expected, individuals with a high sense of quality of life—both general and pertaining to specific dimensions—more often chose positive religious strategies, whereas participants with a low sense of quality of life more often chose negative strategies. The exception was the metaphysical aspect of the quality of life: individuals with a high intensity of this dimension more often chose some of the positive as well as negative religious strategies.     

Pure Modal Logic of Names and Tableau Systems

By a pure modal logic of names (PMLN) we mean a quantifier-free formulation of such a logic which includes not only traditional categorical, but also modal categorical sentences with modalities de re and which is an extension of Propositional Logic. For categorical sentences we use two interpretations: a “natural” one; and Johnson and Thomason’s interpretation, which is suitable for some reconstructions of Aristotelian modal syllogistic (Johnson in Notre Dame J Form Logic 30(2):271–284, 1989; Thomason in J Philos Logic 22(2):111–128, 1993 and J Philos Logic 26:129–141, 1997. In both cases we use Johnson-like models (1989). We also analyze different kinds of versions of PMLN, for both general and singular names. We present complete tableau systems for the different versions of PMLN. These systems enable us to present some decidability methods. It yields “strong decidability” in the following sense: for every inference starting with a finite set of premises (resp. every syllogism, every formula) we can specify a finite number of steps to check whether it is logically valid. This method gives the upper bound of the cardinality of models needed for the examination of the validity of a given inference (resp. syllogism, formula).     

The first signs of prospective memory

We conducted a study to examine the impact of motivation and length of delay on performance on prospective memory (PM) tasks in 2-year of children. A total of 158 children aged exactly 24 months were asked to perform a naturalistic PM task. Length of delay (10?min; 35?min) and motivation (high; very high) were between-subjects factors. Two thirds of children had to be excluded from the analysis because of poor retrospective memory for the PM task instructions which were no longer remembered at the end of the session. For the children who did remember the instructions, both motivation and delay had significant effects on PM. Also, their PM performance was reliably above zero, even after the long delay. The findings indicate that when children as young as 24 months are able to remember the PM task instructions they can reliably succeed in PM tasks that are intrinsically motivating for them.
