How Participative Safety Matters More in Team Innovation as Team Size Increases

Purpose

The purpose of this study was to investigate if there is a moderating relation between team size and team innovation.

Design/Methodology/Approach

Data used in statistical analyses were obtained from 531 employees in 124 technology research teams.

Findings

The findings support the hypothesis, showing that not only team size, but also team size together with participative safety facilitates team innovation.

Implications

The findings show that not only large teams, but also large teams with participative safety are innovative. Team leaders thus need to ensure that collaborative rather than competitive environment prevails in their teams.

Originality/Value

This is one of the first studies to assess team innovation by patents received and to provide evidence of the moderating relation of participative safety between team size and team innovation.     

Beneficial effects of a music listening intervention on neural speech processing in 0–28-month-old children at risk for dyslexia

Familial risk for developmental dyslexia can compromise auditory and speech processing and subsequent language and literacy development. According to the phonological deficit theory, supporting phonological development during the sensitive infancy period could prevent or ameliorate future dyslexic symptoms. Music is an established method for supporting auditory and speech processing and even language and literacy, but no previous studies have investigated its benefits for infants at risk for developmental language and reading disorders. We pseudo-randomized N∼150 infants at risk for dyslexia to vocal or instrumental music listening interventions at 0–6 months, or to a no-intervention control group. Music listening was used as an easy-to-administer, cost-effective intervention in early infancy. Mismatch responses (MMRs) elicited by speech-sound changes were recorded with electroencephalogram (EEG) before (at birth) and after (at 6 months) the intervention and at a 28 months follow-up. We expected particularly the vocal intervention to promote phonological development, evidenced by enhanced speech-sound MMRs and their fast maturation. We found enhanced positive MMR amplitudes in the vocal music listening intervention group after but not prior to the intervention. Other music activities reported by parents did not differ between the three groups, indicating that the group effects were attributable to the intervention. The results speak for the use of vocal music in early infancy to support speech processing and subsequent language development in infants at developmental risk.

Research Highlights

• Dyslexia-risk infants were pseudo-randomly assigned to a vocal or instrumental music listening intervention at home from birth to 6 months of age.
• Neural mismatch responses (MMRs) to speech-sound changes were enhanced in the vocal music intervention group after but not prior to the intervention.
• Even passive vocal music listening in early infancy can support phonological development known to be deficient in dyslexia-risk.
