Using Virtual Reality to Study Spatial Mapping and Threat Learning

This data is from a virtual reality threat conditioning study comparing those that learned the contingencies of the paradigm (learners) and those who did not. Participants collected flowers in a virtual environment one at a time, and after collecting a flower, they rated on a scale (0-9) how likely they were to get a shock (9 being more likely). Unknown to participants, half of the environment predicted shock (at reinforcement rates 35%, 50%, and 60%), while the other half was "safe". Participants also collected and returned objects to their original location 4 times each. 2 objects were located in the "safe" half, two were located in the dangerous half. The distance between where the participant placed the object and it's original location was measured. State and trait anxiety scores were measured before (state and trait) and after (state only) the conditioning task. Participants also completed the Raven's Progressive Matrices before the task. During the task, skin conductance level was collected as participants approached a flower (SCL) and after they collected the flower and rated the likelihood of shock but before receiving a shock (SCR). At the end of the task, participants were asked to name the objects they collected and their locations. <br><b>Learner:</b> 1 - learner; 0 -non-learner<b>Reinforcement rate</b>: Shock reinforcement rate: 35%, 50%, 60%<b>Age:</b> Participant's age<b>Gender: </b>Participant's gender<b>STAI_State_Pre:</b> State Trait Anxiety Inventory score; State, before task<b>STAI_State_Post</b>: State Trait Anxiety Inventory score; State, after task<b>STAI_Trait</b>: State Trait Anxiety Inventory score; Trait<b>Raven</b>: Raven visual IQ score<b>Number_mem_obj</b>: Number of objects remembered<b>Number_mem_loc:</b> Number of object locations remembered<b>SCR_Safe_n:</b><b><strong> </strong></b>SCR (jitter period) for n'th safe trial; normalized and range-corrected<b>SCR_Dang_n: </b>SCR (jitter period) for n'th dangerous trial; normalized and range-corrected<b>SCL_Safe_n:</b> SCL (approaching flower) for n'th safe trial; normalized and range-corrected<b>SCL_Dang_n:</b> SCL (approaching flower) for n'th dangerous trial; normalized and range-corrected<b>Exp_Safe_n:</b> Shock expectation rating for n'th safe trial<b>Exp_Dang_n:</b> Shock expectation rating for n'th dangerous trial<b>Dist_n_k:</b> Distance of object n, iteration k<b>Condition</b> A - Dangerous objects: 1, 2; Safe objects: 3, 4; B - Dangerous objects: 3, 4; Safe objects: 1, 2;<br>
