Discrepancy between subjective autobiographical reliving and objective recall: The past as seen by Alzheimer’s disease patients

This paper investigated whether Alzheimer’s disease (AD) patients may demonstrate a discrepancy between subjective autobiographical reliving and objective recall. To this end, 31 AD patients and 35 controls were asked to retrieve three autobiographical memories. For each memory, participants were asked to rate its subjective characteristics (e.g., reliving, travel in time, visual imagery…). Besides this subjective assessment, we analyzed recall objectively with regard to specificity. Results showed poorer subjective autobiographical reliving and objective recall in AD patients than in controls. A discrepancy (i.e., higher level of subjective reliving than of objective recall) was observed in AD but not in control participants. Despite a compromise in their objective recall, AD patients seemed to attribute a high value to their subjective autobiographical experience. This discrepancy can be attributed to a potential genuine consciousness experience in which mild AD patients can, to some extent, experience some subjective features of the past.     

“How old do you feel today at work?” Work-related drivers of subjective age in the workplace

ABSTRACT

Most Western societies face the challenge of steadily ageing workforces. In recent decades, research on ageing has intensively focused on the subjective age concept to understand the challenges and risks of increasingly ageing workforces. Nevertheless, the subjective age construct is subject to several conceptual uncertainties, namely, regarding its stability and potential work-specific drivers of subjective age. We address these limitations by a) investigating the stability of subjective age in a worker sample, and b) identifying work-specific drivers (e.g., negative work events, positive work events, work stress) of subjective age perceptions. Building on social identity and lifespan theories, we test our conceptual assumptions with an online sample of 168 U.S. employees, applying growth curve modelling in a daily diary study over one workweek. Results indicate that subjective age is a mutable construct and varies between- and within-person in the course of a workweek. We identify positive work events and work stress as between-person drivers and negative work events as a within-person driver of subjective age. We discuss theoretical implications of these findings as well as consequences for practitioners.     

Taking a deeper look inside autonomous and interdependent teams: why,how, and when does informational dissimilarity elicit dysfunctional versus beneficial effects

ABSTRACT

Organizations increasingly use cross-functional teams, characterized by autonomy and interdependence, to improve innovation and to adapt to a dynamic business environment. Based on this trend, prior research started to investigate informational dissimilarity (employee’s dissimilarity relative to teammates regarding education, job specialization, and expertise) in teams. Two key team outcomes are 1) team members’ satisfaction with the team and 2) the team’s proactivity. Paradoxically, some researchers reported dysfunctional informational dissimilarity effects on employee outcomes, while some reported beneficial effects. To integrate opposing informational dissimilarity effects, we apply the categorization-elaboration model of team diversity. We theorize that perceived informational dissimilarity can elicit simultaneously dysfunctional effects on satisfaction with the team and beneficial effects on the team member’s proactivity. We specify the mechanisms of both effects by investigating the mediating roles of peer unfairness (representing dysfunctional informational dissimilarity effects) and information elaboration (representing beneficial informational dissimilarity effects). To reconcile these contradicting processes, we analyse the role of trust. We conducted a survey study at three different measurement time points with team members from different organizations. The results indicate that trust in teammates dampens dysfunctional informational dissimilarity effects and amplifies beneficial effects.     

On no man’s land: Subjective experiences during unresponsive and responsive sedative states induced by four different anesthetic agents

To understand how anesthetics with different molecular mechanisms affect consciousness, we explored subjective experiences recalled after responsive and unresponsive sedation induced with equisedative doses of dexmedetomidine, propofol, sevoflurane, and S-ketamine in healthy male participants (N = 140). The anesthetics were administered in experimental setting using target-controlled infusion or vapouriser for one hour. Interviews conducted after anesthetic administration revealed that 46.9% (n = 46) of arousable participants (n = 98) reported experiences, most frequently dreaming or memory incorporation of the setting. Participants receiving dexmedetomidine reported experiences most often while S-ketamine induced the most multimodal experiences. Responsiveness at the end of anesthetic administration did not affect the prevalence or content of reported experiences. These results demonstrate that subjective experiences during responsive and unresponsive sedation are common and anesthetic agents with different molecular mechanisms of action may have different effects on the prevalence and complexity of the experiences, albeit in the present sample the differences between drugs were minute.     

Selfhood triumvirate: From phenomenology to brain activity and back again

Recently, a three-dimensional construct model for complex experiential Selfhood has been proposed (Fingelkurts, Fingelkurts, & Kallio-Tamminen, 2016b,c). According to this model, three specific subnets (or modules) of the brain self-referential network (SRN) are responsible for the manifestation of three aspects/features of the subjective sense of Selfhood. Follow up multiple studies established a tight relation between alterations in the functional integrity of the triad of SRN modules and related to them three aspects/features of the sense of self; however, the causality of this relation is yet to be shown. In this article we approached the question of causality by exploring functional integrity within the three SRN modules that are thought to underlie the three phenomenal components of Selfhood while these components were manipulated mentally by experienced meditators in a controlled and independent manner. Participants were requested, in a block-randomised manner, to mentally induce states representing either increased (up-regulation) or decreased (down-regulation) sense of (a) witnessing agency (“Self”), or (b) body representational-emotional agency (“Me”), or (c) reflective/narrative agency (“I”), while their brain activity was recorded by an electroencephalogram (EEG). This EEG-data was complemented by first-person phenomenological reports and standardised questionnaires which focused on subjective contents of three aspects of Selfhood. The results of the study strengthen the case for a direct causative relationship between three phenomenological aspects of Selfhood and related to them three modules of the brain SRN. Furthermore, the putative integrative model of the dynamic interrelations among three modules of the SRN has been proposed.     

The conjunction fallacy: a misunderstanding about conjunction?

It is easy to construct pairs of sentences X, Y that lead many people to ascribe higher probability to the conjunction X-and-Y than to the conjuncts X, Y. Whether an error is thereby committed depends on reasoners’ interpretation of the expressions “probability” and “and.” We report two experiments designed to clarify the normative status of typical responses to conjunction problems.     

The psychological distance of memories: Examining causal relations with mood and self-esteem in young,middle-aged and older adults

Three studies examined the self-enhancement function of autobiographical memory (measured with subjective temporal distance of memories). Participants recalled a memory of an attained and a failed goal and rated the subjective distance between each memory and the present. Study 1 showed that young adults with higher self-esteem felt closer to memories of attained goals and farther from failure memories than those with lower self-esteem. In Study 2, young, middle-aged and older adults with higher self-esteem felt closer to success memories, whereas self-esteem was unrelated to the temporal distance of failure memories. In both studies, feeling closer to success memories (and far from failure) led to enhanced mood. In Study 3, state self-esteem was experimentally manipulated. The manipulation had no effect on young and older adults, but middle-aged adults whose self-esteem was decreased, felt closer to success memories than failure memories. Results are discussed in relation to the temporal self-appraisal theory.     

“Not performing worse but feeling older !” the negative effect of the induction of a negative aging stereotype

The present research investigated the effect of the induction of a negative stereotype on older adults’ performance during an endurance task, and how this stereotype influenced older adults’ subjective age. Thirty-four old women were randomly assigned to one of the two conditions: a negative stereotype condition and a nullified-stereotype condition. They performed an endurance task consisting of maintaining 30% of their maximal strength, as long as possible. Then, they answered a questionnaire including subjective age measurement. Contrary to expectations, the induction of the negative stereotype did not influence participants’ endurance performance. However, participants in the negative stereotype condition felt older than participants in the nullified-stereotype condition. As subjective age is relevant to late-life health outcomes, such as walking speed or mortality risk, it seems necessary to implement some strategies to decrease the negative effect of the negative stereotype on subjective age.
