You can use it when you want to describe someone teaching a group of students, or to explain something that involves teaching a group of people. For example: "The professor was instructing the group of students in the history of philosophy."
Zoos and other environmentally-focused tourist destinations often hire educators to work with children and adults, instructing groups on nature, wildlife, and conservation programs run by the organization.
At the time of the study, the first author (male) had a master's degree and one year of experience with instructing groups in this type of research settings.
The study employed an experimental design over a 6 month period with 34 students assigned to either an explicitly instructed group or a control group receiving no instruction.
The study employed an experimental design over a 12 week period with 26 students assigned to either an explicitly instructed group or a control group receiving no instruction.
In the instructed group, participants were asked to form positive sentence and avoid the negative alternative in the emotional blocks.
As anticipated, participants avoided negative sentences in the spontaneous group (25% negative sentences, logistic regression z = −11, p<0.001) as well as in the instructed group (0.5% negative sentences).
A first group was simply told to form grammatically correct sentences, eliciting the spontaneous avoidance of the negative alternative (spontaneous group); a second group, in contrast, was explicitly instructed to avoid forming negative sentences (instructed group).
However, WMC scores did predict the proportion of well-formed sentences (negative or positive) formed in the task (z = 3.8, p<0.001), both in the spontaneous (z = 3.5) and in the instructed group (z = 2.7).
By contrast, significantly fewer participants in the instructed group endorsed these beliefs (chi square ps < .001), instead they predominately endorsed the ' equally likely' statement in each stimulus.
While the non-instructed group showed a standard PIT effect (where the beer and chocolate stimuli primed the beer and chocolate response, respectively), this PIT effect was absent in the instructed group.
