Several hypotheses were supported. 6 For Lateral units experiencing sequential dependence,Broad scope MASs were significantly over-represented (H2b), while Rudimentary MASs were significantly under-represented (H2a).
Furthermore,Rudimentary MASs were significantly over-represented among Simple units under conditions of reciprocal interdependence (H6a). In addition, in Simple units facing reciprocal interdependence, the proportion of Broad scope MASs was, as expected,lower than the proportion across the overall sample (H6b). Also for Simple units experiencing
sequential interdependence, the proportions of Rudimentary MASs (62%) and Broad scope MASs (19%) differ from their proportions in the overall sample (46% and 33%, respectively) in the proposed direction (H3a and H3b). However,
these differences were not statistically significant.
