The biggest reaction would likely be to the video’s overt sexuality,a violation of the ideal of disembodied hegemonic masculinity, even as displays of sexualizedheteronormative masculinity are routinely permitted.Sexualized heteronormative femininity is also permitted, and even used in the service ofpromoting women in engineering. The Nerd Girls trailer27 shows young female able-bodiedengineers donning pink capes and black glasses, heavy makeup and stiletto heels; these womenconform to hegemonic feminine beauty ideals and body types in much the same way as the sexynerds (though there is greater racial diversity).

Itis plausible that the students' long-term store of information regarding the solids presented inthis task has been coded in a standard orientation and possibly using a coding system whichhas become more verbal and semantic than visual. The geometries may have been codedverbally by using a verbal descriptive system, which is amodal in nature. Semantic codingmay also have been utilised where the representation of the geometry in long-term memoryhas been assigned to some class, possibly one governed by a pictorial projection system.This could be due to the conditioning effect, previously discussed by
