Thus, fear in the test context seems to vary inversely with the values of co-present cues during extinction in Context B. Results imply that cue value is actually reduced by extinction procedures rather than merely being opposed by a growing inhibitory process. Implications for theories of ...
Using Pavlovian fear conditioning and extinction procedures in rats, we show that pharmacological inactivation of the RE dramatically increases freezing behavior during both the encoding and later retrieval of an extinction memory. This extinction impairment was not state-dependent. This pattern of ...
(The within-session testing method was based on the procedures used by Rescorla & Cunningham, 1977, 1978.) The average ITI throughout the session was 9 min. Comparison of the SE–ExtX and NE–ExtX groups on this test should show whether the extinction trials of Y preceding the test of ...
2.2. Procedures After providing informed consent, the participants filled out self-report questionnaires and completed clinical interviews administered by doctoral-level psychologists. During a laboratory visit, the participants then completed a dark-enhanced startle task consisting of three phases, as previo...
A number of risk categories for cattle breeds in these countries were formulated using this information and following the procedures suggested earlier. The results from the four countries are presented in Appendix Tables A1–A4. 3.1.1. Category 1: Breeds That Have Been Declared Extinct 3.1.1.1. ...
