Clearly, untreated bees, which did not experience any treatment in the pre-exposure phase, did not differ in their acquisition performance from bees that received a neutral stimulus such as a mechanosensory stimulation or water (F2,138 = 0.06, NS).
It remains to be tested whether HAB and NAB mice would differ in fear acquisition when using a weaker conditioning protocol, such as applying a foot shock just above the flinching threshold (e.g. 0.35 mA).
These proteins share the sequence spanning the periplasmic binding protein (PBP) domain (PF00352) but differ in the acquisition of a DNA-binding domain by RbsR.
Wild-type and M4 KO mice did not differ in the acquisition of the pairwise visual discrimination task (Fgenotype(1,216) = 0.15, ns; Fdays(11,216) = 19.40, p < 0.001; Fgenotype×days(11,216) = 1.14, ns; see Figure 10D).
The two strategies differ in many ways: Acquisition deals are competitive, based on market prices, and risky; alliances are cooperative, negotiated, and not so risky.
When presented with odor-food associations, long-term solitarious and gregarious desert locusts show comparable memory retention, but they differ in aversive memory acquisition, with solitarious locusts manifesting aversion sooner than gregarious locusts.
In order to compare all the possibilities, four different systems for heliox administration were compared: a standard open circuit with a mask for non-invasive ventilation, a custom made semi-closed circuit and two standard anesthesia machines differing in their acquisition costs: a low-cost anesthesia machine and an advanced anesthesia machine.
For example, studies investigating perception of auditory, visual and audiovisual speech signals in a large number of participants that differ in their age of acquisition and proficiency of the second language are needed.
Theories abound, from clinical biological hypotheses (language acquisition may differ in boys; sex-linked traits could affect learning styles and test-taking) to the quirky role of gender bias in the classroom.
Emerging research is advancing the view that the capacity to acquire language can be applied equally to two languages as to one but that bilingual and monolingual acquisition nonetheless differ in some nontrivial ways.
