Measurements were taken at several points in time over a 1 2 h period in order to test the effects of marginal enrichments, namely the provision of a jerrycan canister (Experiments 1a and 1b) and the provision of some sawdust and/or removal of the metal chain (Experiment 2).
Take, for example, a transmission chain experiment by Mesoudi et al. (2006), in which multiple stories varying in their social complexity were passed along chains of participants.
It would be informative to explicitly pit different biases against each other and test their relative strength in a standard transmission chain experiment (hence characterised by transformative transmission) versus a simple task of choosing which story to pass on (preservative).
With the chain experimenting with a variety of changes, like closing stores and dropping warm breakfast sandwiches, the chief executive, Howard Schultz, said monthly sales "will not be an effective indicator of our performance".
To do this, we conduct transmission chain experiments (cf Curio et al. 1978; Galef and Allen 1995; Laland and Williams 1997).
For the envy-chain experiment in Sunday's Times Magazine, we let each subject — instead of our own editors — tell us whose dwelling we should feature next.
With the best of intentions, companies up and down supply chains experiment with isolated efforts to improve sustainability only to encounter a long string of unanticipated consequences, often in the form of financial, social, or environmental costs.
For cross-linked ubiquitin chains experiment a mixture of 90% DOPC, 5% DGS-NiNTA, 5% Oregon-green DHPE was used.
Facing this reality, a new generation of supply-chain experiments are borrowing tactics from conventional development efforts.
"Chained" experiments with musical buildup and subtle flourishes, and muffled 2-step beats.
And, strikingly, in transmission-chain experiments with human adults, opportunities for pedagogy or imitation have been found to be no more effective than simply seeing the end products in allowing cumulative development of traditions [21].
