Tidskriftsartikel (refereegranskat)abstract
- This study has explored the relation between dance achievement and alexithymia in a larger Swedish population sample (Swedish Twin Registry) with a study sample of 5431 individuals. Dance achievement (CAQ) was assessed in relation to Alexithymia (Toronto Alexithymia Scale, TAS-20) including the three subscales: Difficulty Identifying Feelings (DIF), Difficulty Describing Feelings (DDF), and Externally Oriented Thinking (EOT). The results show a significant negative association between the TAS subscale (EOT) and creative achievement in dance. A high EOT score corresponds to poor ability to communicate feelings to the environment. There was no consistent association between the other factors DIF and DDF and dance achievement. Dance activity and training seem to be involved in the body's emotional interplay with others. Embodied cognition, emotional perception, and action are discussed as factors relevant to measuring the skill of a dancer.

- Flow is a subjective experience of high but effortless attention, enjoyment, and low self-awareness that can occur during the active performance of challenging tasks. The dispositional proneness to experience flow is associated with personality traits that are known to be influenced by dopaminergic neural systems. Here, for the first time, we investigated relations between flow proneness and dopaminergic function. Specifically, we tested the hypothesis that the availability of dopamine D2-receptors in the striatum is positively associated with flow proneness. Striatal D2-receptor availability was measured in a sample of 25 healthy adults using positron emission tomography and [C-11]raclopride. Flow proneness was measured using the Swedish Flow Proneness Questionnaire. As hypothesized, there was a significant correlation (r = .41) between striatal D2-receptor availability and flow proneness. An exploratory analysis of striatal subregions showed that the relation was mainly driven by the dorsal striatum, with a significantly higher correlation in the putamen than in the ventral striatum. The findings constitute the first demonstration of an association between flow proneness and dopaminergic function. We suggest that the proneness to experience flow is related to personality dimensions that are under dopaminergic control and characterized by low impulsiveness, stable emotion, and positive affect.

- Expert performance is commonly accompanied by a subjective state of optimal experience called flow. Previous research has shown positive correlations between flow and quality of performance and suggests that flow may function as a reward signal that promotes practice. Here, piano playing was used as a flow-inducing behavior in order to analyze the relationship between subjective flow reports and psychophysiological measures. Professional classical pianists were asked to play a musical piece and then rate state flow. The performance was repeated five times in order to induce a variation in flow, keeping other factors constant, while recording the arterial pulse pressure waveform, respiration, head movements, and activity from the corrugator supercilii and zygomaticus major facial muscles. A significant relation was found between flow and heart period, blood pressure, heart rate variability, activity of the zygomaticus major muscle, and respiratory depth. These findings are discussed in relation to current models of emotion, attention, and expertise, and flow is proposed to be a state of effortless attention, which arises through an interaction between positive affect and high attention.

Thinking Outside a Less Intact Box : Thalamic Dopamine D2 Receptor Densities Are Negatively Related to Psychometric Creativity in Healthy Individuals

Tidskriftsartikel (refereegranskat)abstract
- Several lines of evidence support that dopaminergic neurotransmission plays a role in creative thought and behavior. Here, we investigated the relationship between creative ability and dopamine D2 receptor expression in healthy individuals, with a focus on regions where aberrations in dopaminergic function have previously been associated with psychotic symptoms and a genetic liability to schizophrenia. Scores on divergent thinking tests (Inventiveness battery, Berliner Intelligenz Struktur Test) were correlated with regional D2 receptor densities, as measured by Positron Emission Tomography, and the radioligands [C-11] raclopride and [C-11]FLB 457. The results show a negative correlation between divergent thinking scores and D2 density in the thalamus, also when controlling for age and general cognitive ability. Hence, the results demonstrate that the D2 receptor system, and specifically thalamic function, is important for creative performance, and may be one crucial link between creativity and psychopathology. We suggest that decreased D2 receptor densities in the thalamus lower thalamic gating thresholds, thus increasing thalamocortical information flow. In healthy individuals, who do not suffer from the detrimental effects of psychiatric disease, this may increase performance on divergent thinking tests. In combination with the cognitive functions of higher order cortical networks, this could constitute a basis for the generative and selective processes that underlie real life creativity.

- Musical engagement is influenced by both environmental and genetic factors. Here, we explored nongeneticinfluences on musical engagement by performing semi-structured interviews of 10 Swedishmonozygotic twin pairs that were highly discordant for piano practicing. The interviews were organizedinto five sections – (i) perceived reasons for the discordance; (ii) childhood differences in specific musicrelated variables; (iii) strong memories of music; (iv) the perceived meaning of music in life and forhealth; and (v) language interests – and analyzed using response categorization. The playing twins froman early age found music more interesting and enjoyable than their co-twins and also gave richer andmore elaborate descriptions of the meaning of music in life, in several cases emphasizing that music wasimportant for their personal identity. In line with this, an analysis of previously collected web questionnairedata showed that the playing twins had a significantly higher openness to experience and pronenessto experience flow during musical activities. In contrast, the twins reported essentially no within-pairdifferences in the musical engagement of their peers, parental support, music teacher, ensemble playing,public performances, and their interest and aptitude for languages. The interviews gave no indication thatthe differences in musical engagement were caused by systematic environmental influences that wereconsistent across twin pairs. Rather, the respondents presented a wide range of different explanations fortheir discordance in musical activity, suggesting that the remaining influences on musical engagement,when genetics and family environment are controlled for, may be highly individual and idiosyncratic.

- Extraverted individuals are sociable, behaviorally active, and happy. We report data from a voxel based morphometry study investigating, for the first time, if regional volume in gray and white matter brain regions is related to extraversion. For both gray and white matter, all correlations between extraversion and regional brain volume were negative, i.e. the regions were larger in introverts. Gray matter correlations were found in regions that included the right prefrontal cortex and the cortex around the right temporo–parietal junction – regions that are known to be involved in behavioral inhibition, introspection, and social-emotional processing, e.g. evaluation of social stimuli and reasoning about the mental states of others. White matter correlations extended from the brainstem to widespread cortical regions, and were largely due to global effects, i.e. a larger total white matter volume in introverts. We speculate that these white matter findings may reflect differences in ascending modulatory projections affecting cortical regions involved in behavioral regulation.

- Low neuroticism and high intelligence are both related to lower intertrial variability in reaction time tasks. However, intelligence and neuroticism are weakly related traits, which suggests that they may be related to different sources of timing variability. The relation between intelligence and timing variability has recently been investigated using isochronous serial interval production (ISIP). This is a simple, automatic timing task where participants first synchronize movements with an isochronous sound sequence and then continue with self-paced production of a sequence of intervals with the same inter-onset interval (IOI). For all IOIs, local interval-to-interval variability correlated strongest with intelligence. The purpose of the present study was to test whether neuroticism, in contrast, is related to the non-local component of ISIP variability, i.e. drift or gradual changes in response IOI. We found a significant correlation of r = 0.42 between drift and neuroticism, thereby confirming the hypothesis. We suggest that this finding reflects that individuals high on neuroticism have more frequent slips in top–down cognitive control mechanisms. These cognitive failures may in turn interfere with the processing of previously produced intervals in short-term memory, which gives an unstable IOI in the ISIP task, i.e. drift.

Cortical changes during the learning of sequences of simultaneous finger presses
- 2023

Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- The cortical alterations underpinning the acquisition of motor skills remain debated. In this longitudinal study in younger adults, we acquired performance and neuroimaging (7T MRI) measures weekly over the course of 6 weeks to investigate neural changes associated with learning sequences of simultaneous finger presses executed with the non-dominant hand. Both the intervention group (n = 33) and the control group (n = 30) showed general performance improvements, but performance improved more and became more consistent for sequences that were intensively trained by the intervention group, relative to those that were not. Brain activity for trained sequences decreased compared with untrained sequences in the bilateral parietal and premotor cortices. No training-related changes in the primary sensorimotor areas were detected. The similarity of activation patterns between trained and untrained sequences decreased in secondary, but not primary, sensorimotor areas, while the similarity of the activation patterns between different trained sequences did not show reliable changes. Neither the variability of activation patterns across trials, nor the estimates of brain structure displayed practice-related changes that reached statistical significance. Overall, the main correlate of learning configural sequences was a reduction in brain activity in secondary motor areas.

In this longitudinal study in younger adults, we acquired performance and neuroimaging (7 T MRI) measures weekly over the course of 6 weeks to investigate neural changes associated with learning sequences of simultaneous finger presses executed with the non-dominant hand. Both the intervention group (n = 33), which practiced the finger sequences at home, and thecontrol group (n = 30, no home practice) showed general performance improvements, but performance improved more and became more consistent for sequences that were intensively trained by the intervention group, relative to those that were not. Brain activity for trained sequences decreased compared with untrained sequences in the bilateral parietal and premotor cortices. No training-related changes in the primary sensorimotor areas were detected.
