Dream and daydream: differences and similarities

Did you know that daydreams reflect events from the previous two days and “night” dreams resemble a fictional plot?

When psychotic-like experiences become distressing?

Evidence suggests that psychotic-like experiences (PLEs) exist along a continuum progressing from benign subclinical phenomena at one end to severe psychotic symptoms at the other. Among children, PLEs are common and typically benign, but in some cases, they can be distressing and functionally impairing. In the scope of the research project 194/12 - Characterising developmental trajectories of brain function from childhood into adolescence, supported by the BIAL Foundation, Kristin Laurens aimed to examine whether the likelihood of distressing or impairing PLEs differed according to the type of co-occurring psychopathology symptoms. It was observed that children with co-occurring internalising and/or externalising problems had greater odds of distressing and/or impairing PLEs compared to children without co-occurring psychopathology (PLEs only). The implications of these results are discussed in the article Increased likelihood of distressing and functionally impairing psychotic-like experiences among children with co-occurring internalising and externalising problems published in the journal Schizophrenia Research.

Effects of aging on face processing

In the scope of the research project 249/16 - Healthy aging and economic decision-making: neuropsychophysiological examination of the affect-integration-motivation framework of decision-making in aging brain, supported by the BIAL Foundation, João Marques-Teixeira and colleagues studied the impact of aging on face processing. It was observed that older adults, compared to younger adults, engage additional neural resources during the visualization of facial expressions of emotion, as well as non-facial stimuli (houses and mugs). Aging may hamper the neural processing of facial expressions of emotion, and this difficulty may be exacerbated during the identification of emotions from faces of their own-age peers. More results are available in the paper Effects of aging on face processing: An ERP study of the own-age bias with neutral and emotional faces published in Cortex.

Dispositional mindfulness and startle reactivity

Veena Kumari, principal investigator of the research project 92/18 – Attending mindfully: A psychophysiology study of sensory processing in meditators, supported by the BIAL Foundation, examined possible associations between dispositional mindfulness and alexithymia and found a negative association. In addition, it was assessed the eye-blink startle responses to acoustic stimuli of varying intensity and observed a positive association between startle response habituation and dispositional mindfulness (i.e., more habituation in individuals with a high level of naturally-occurring mindfulness). Similar results were also obtained by long-term mindfulness practitioners engaging in mild-to-moderate meditation practices, suggesting similar sensory information processing styles. These findings are reported in the paper Dispositional mindfulness, alexithymia and sensory processing: Emerging insights from habituation of the acoustic startle reflex response published in International Journal of Psychophysiology.
