The COVID-19 pandemic created a unique set of circumstances in which to investigate collective memory and future simulations of events reported during the onset of a potentially historic event. Between early April and late June 2020, we asked over 4,000 individuals from 15 countries across four continents to report on remarkable (a) national and (b...

Over the past 10 years, Oosterhof and Todorov’s valence–dominance model has emerged as the most prominent account of how people evaluate faces on social dimensions. In this model, two dimensions (valence and dominance) underpin social judgements of faces. Because this model has primarily been developed and tested in Western regions, it is unclear w...
Article
We aimed to explore autobiographical memory for repeated events. For that aim, five instances of the same event category (i.e. last, first, random, distinct, and typical vacation) were collected from 57 (32 females) adults (Mage = 21.8; SDage = 2.0). Participants also provided the vacation scripts they have in mind. The last instances were expected...

Open autobiographical memories are personal life experiences on which an individual does not have a closure. After retrieving open memories, it is unknown whether emotional regulation, a tendency to recall positive memories after recalling negative memories, is still effective as in negative memories. Current study aims to test for the presence of...

There has been evidence that depression is associated with difficulties in implementing adaptive strategies for emotion regulation. In the present research, we examined the effect of mild to moderate levels of depression in a nonclinical undergraduate sample and tested whether depressive affect impairs the implementation of the emotion regulatory f...
Article
The consistency of earliest memories in content, dating, and memory qualities was investigated. A total of 84 (27 males; Mage = 24.93, SD = 1.36) adults reported earliest memories, estimated ages, and rated their recollections on memory qualities with a two-year time lag. At Time 2, their original reports at Time 1 were presented and they were aske...
Article
We investigated the relationship between components of rumination, brooding and reflection, and autobiographical remembering by testing whether voluntary and involuntary rehearsal mediated rumination-related variation in the sensory-affective and metacognitive features of memory experience. We focused on achievement and failure memories as both are...
Article
Two studies were conducted to explore the effect of the most frequent life events on the reminiscence bump. The first study examined the life scripts and autobiographical memories of 44 adults [Mage = 62.8, standard deviation (SD) = 2.8] by removing the most frequent 10 life events. The regular reminiscence bump disappeared in the distribution of b...

Two studies reported that twins may dispute ownership of autobiographical experiences. One observation made in both studies was that the events that were disputed by the twins were rather ordinary events. In the present study, we tested the idea that the disputed memories are such ordinary and mundane events. A brief narrative description of disput...

Project
Autobiographical memory qualities differ in episodes of psychiatric disorders and some of these differences have been identified as risk factors for psychopathology. However, there is limited evidence on how memory characteristics relate to dimensional models of psychopathology. Here, we investigate episodic details, vividness and vantage point in relation to emotion regulation difficulties and cognitive avoidance.
Project
Open autobiographical memories are personal past events that people do not have closure. In the current project, we investigate open memories and their possibility of being closed in the future.
Project
In the current study, we created a scale to measure the extent to which individuals need emotional closure over past events.
