Acquired equivalence and generalized suppression in a virtual reality environment

Acquired equivalence was investigated using a virtual reality conditioned suppression task administered in a first-person-shooter game. Two visual cues, A1 and B1, were followed by a tone (O1), and another two cues, A2 and B2, were followed by another tone (O2). During differential Pavlovian conditioning, A1 was paired with an instructed unconditioned stimulus (US) consisting of a flashing white screen, whereas A2 was not. All cues and outcomes were then presented at test, in the absence of the US, and suppression ratios were calculated for multiple response topographies (shots, hits, and breaks). Clear evidence of the suppression of shots was seen for A1 and B1, with no suppression being seen for either A2 or B2. Presentations of O1 and O2 resulted in significant suppression of shots and hits, whereas only O1 led to the suppression of breaks. The US expectancy ratings were consistent with these behavioral results. The findings are discussed in the light of differing accounts of acquired equivalence.     

Exploring the Popperian Framework in a Pre‐service Teacher Education Program

The study reported in this article is derived from a critical analysis of the work of 28 pre‐service teachers enrolled in the course “Teaching elementary language arts” in a Bachelor of Education concurrent program in a southern State university. The pre‐service teachers were taught how to use an innovative knowledge‐building framework based on the ideas of the philosopher of science, Karl Popper. Two samples of pre‐service teachers’ writing were analyzed to provide evidence of whether they support the occurrence of growth and development of professional knowledge. This study provides some indication of Popper’s framework potential as an effective critical analysis framework for achieving this goal.
