    Yes, 'emotional selection' as they call it, could be a case of 'cultural selection' (which is the more general term of Cavalli-Sforza and Feldman). I mentioned this Heath/Bell/Sternberg paper briefly in my last JoM paper - it's down at the bottom of the rather rambling paragraph below.... Basically, it seems that cultural selection occurs, but the question in a lot of cases is why. One answer is that it is because of emotional selection, but again you could ask why some things are emotionally selected.

    and the paragraph:
     from http://jom-emit.cfpm.org/2002/vol6/gatherer_d.html

    It is clear that a `random walk' pattern of meme incidence over the iterations is more common than the
    `contagionist paradigm' sigmoid curve, which only occurs in rather `pure' situations. Random walk-like effects may be genuinely random because of the stochastic nature of the system (simulation 3), because of balanced rules in a deterministic system
    (simulation 4), or be anchored pseudo-random walks because of fluctuations around an equilibrium
    (simulations 10 and 11). Good `epidemiological' sigmoid curves in culture seem to require either arbitrary contagiousness (simulations 1 and 2), or a powerful selective force (the unopposed self-fulfilling prophecy of simulation 5). Some aspects of human life may be arbitrarily contagious, for example crowd hysteria (see reviews by Levy & Nail 1993; Marsden 1998). Several authors have worked within the `contagionist paradigm', producing models of traits that spread in an epidemic manner. For instance, Takahasi (1998, 1999) refers to `biased cultural transmission', Cavalli-Sforza and Feldman
    (1984) to `cultural selection', and Sperber (1985, 1996) to the `epidemiology of representations'. In these cases, it is taken for granted that the epidemic trait is either arbitrarily contagious or, in the case of Cavalli-Sforza and Feldman's `cultural selection', that some powerful, and usually unspecified, psychological factor is promoting the spread of the trait. The self-fulfilling prophecy phenomenon of simulation 5 would presumably therefore be a case of
    `cultural selection'. Another example might be
    `prestige-based transmission' (Heinrich 2001) where certain individuals are far more widely copied than others, or `emotional selection' (Heath et al 2001). Blackmore (1999) gives extensive further examples. Cavalli-Sforza and Feldman (1984) also refer to
    `natural selection' on culture, where a cultural trait spreads through genuine adaptiveness in the absence of either arbitrary `biased cultural transmission' or psychological `cultural selection'. Powerful natural selective forces of this kind do indeed also operate in culture, resulting in some sigmoid incidence curves for possession of, in modern times, mobile phones and other useful paraphernalia (Rogers 1995), or, in the Bronze Age, for bronze knives (Renfrew 1987). Hewlett and Cavalli-Sforza (1983) describe an epidemic spread of the use of the crossbow among Pygmies, conferring a great hunting advantage over the traditional bow and arrow.
