AI Article Synopsis
- The study explored how patients with Alzheimer's disease and mixed dementia react emotionally to neutral faces after being given positive or negative background information about them.
- Healthy participants were able to recognize faces and showed significant changes in their emotional ratings, while dementia patients could not recognize the faces but still exhibited changes in their ratings based on the biographical information.
- The findings suggest that even if explicit memory declines in dementia, the ability to acquire and retain implicit emotional responses to stimuli remains intact.
Article Abstract
In this study, we investigated the acquisition of affective dispositions towards neutral faces in patients with Alzheimer's disease and mixed dementia. Participants viewed four affectively neutral male faces from the International Affective Picture System. Biographical information about the depicted persons was presented, which described them in terms of positive or negative traits varying in intensity. Participants were asked to rate the pictures with respect to emotional valence, arousal, and preference prior to and after the presentation of the biographical information. Following a retention interval of 180 min, pictures were rated again and the biographical information was presented once more. Final ratings were obtained after another interval of 1300 min. As expected, healthy control participants identified the faces and recalled parts of the information in the delayed recall test. They showed pronounced changes in affective ratings. Patients did not recognize the faces in a recognition test after the retention intervals, but valence, arousal, and preference ratings were systematically altered by the affective content of biographies. The results suggest that acquisition and maintenance of implicit affective dispositions are preserved in dementia even when explicit memory is impaired.

Effective emotion regulation is critical for maintaining emotional health in the face of adverse events that accumulate over the lifespan. These abilities are thought to be generally maintained in older adults, accompanied by the emergence of attentional biases to positive information. Such age-related positivity biases, however, are not always reported and may be moderated by individual differences in affective vulnerabilities and competencies, such as those related to dispositional negative affect and emotion regulation styles.

Background: With the global population aging rapidly, dementia has become a pressing public health challenge, affecting the cognitive functions and daily activities of older adults worldwide. Enhancing literacy about dementia is a proactive prevention strategy, yet the effectiveness of educational programs can vary based on the target population's background. Thus, understanding dementia knowledge levels across different communities and countries is essential for successful educational interventions.

Background: Attention-deficit/hyperactivity disorder (ADHD) is commonly attributed to neuro-cognitive deficits of genetic and/or prenatal/perinatal environmental origins. Sonuga-Barke proposed an alternative formulation, suggesting that ADHD behaviors are functional expressions of delay aversion-a strong motivational disposition to avoid or escape negative affective states evoked by delay. It is hypothesized that the strength of this disposition, though neuro-biologically rooted, is exacerbated by early negative social interactions during waiting-related encounters.

Background: The globalization of the media market is forcing decision-makers to understand the psychological processes behind local audiences' enjoyment of foreign TV dramas. Transportation is a well-established psychological theory and framework utilized to elucidate and anticipate audience engagement and enjoyment in the cognitive process of experiencing a narrative text. Although there is a substantial body of literature on transportation and media enjoyment, there is a noticeable absence of studies on the relationship between audiences being "transported" into the narrative world of TV dramas and, particularly, the pleasure audiences derive from interacting with media content within a cross-cultural acceptance context.
