Testing apparatus used in the Pilot Study for rats housed in standard (a) and semi-naturalistic (b)cages.

<p>In both cases, the treat cage (48 x 38 x 20 cm) is on the right and is connected to the home cage via a red transparent tunnel (7.6 cm diameter x 7.7 cm long). Tunnel exit into the treat cage was blocked with a piece of Plexiglas during 60 s cue-reward interval. For semi-naturalistic-housed rats, an inverted standard cage was placed inside the home cage. One end of this inverted cage connected to the red tunnel while the other side had a hole (10 cm diameter) covered from the outside with an oversized piece of Plexiglas (‘flap door’) on hinges. A rope system allowed the experimenter to open the flap door when a rat approached, allowing her to enter. This way, rats could not enter unless let in by the experimenter, but once inside, they could exit by pushing on the flap door from the inside. Only one rat was allowed inside at a time.</p

Institutional transparency improves public perception of lab animal technicians and support for animal research - Fig 1

<p>Responses by participants asked questions designed to assess a) warmth, b) competence, and c) social distance for the hypothetical lab animal technician “Cathy,” as well as d) support for the research she does. Participants were randomly asssigned to scenarios that described Cathy as working at either a low (dark blue) or high transparency (light blue) institution, using three different species of research animal (cows, dogs and mice). All individual questions were asked on a 7 point Likert-type scale (1 = not at all; 4 = neutral, 7 = extremely); responses for each of the composite measures shown below were averaged across individual questions. The box plots show the mean (central square), median (solid horizonal line in the middle of the box), 25^th and 75^th percentiles (the upper and lower limits of the box) and 10^th and 90^th percentiles (verticle lines extenting above and below the box).</p

Effect of participant demographics (gender, political leaning, age, education, and income) on composite responses to questions designed to assess a) warmth, b) competence, and c) social distance for the hypotheitical lab animal technician “Cathy,” as well as d) support for the research she does.

<p>All individual questions were asked on a 7 point Likert scale (1 = not at all; 7 = extremely); responses for each of the composite measures below were averaged across individual questions. The effects of participant demographics on these responses are shown by coefficients (slope (B) and S.E.), and the t-value and corresponding probability that these values differ from 0. These values are from general linear model that also included the main effects of transparency and species, and the relevant 2-way interactions. Bold values indicate <i>p</i> = < .05.</p
