Heart-Rate Response during Aversive Conditioning

Psychological Reports, 1970
36 rats were used to determine the effects of: (a) footshock before specific training, (b) CS duration (6 vs 60 sec.), and (c) form of aversive conditioning (CER vs CAR) on heart rate both during the presentation of the CS and between presentations. All three tested variables were effective in modifying the heart-rate response to the CS while only CS ...

Operant Conditioning of Heart Rate

Science, 1962
Delay of shock was made contingent upon acceleration of heart rate in human subjects. The number of accelerations rose across sessions for these subjects and fell for their yoked-controls who received equal amounts of noncontingent shock. A shorter delay produced more accelerations but faster adaptation.

Heart rate conditioning in the rat

Journal of Psychosomatic Research, 1965
Abstract Classical conditioning procedures were used to evaluate the development and extinction of conditioned HR changes in the albino rat. The data suggest that the experimental group (a) developed a generalized HR response to the apparatus, their HR remaining consistently (and on Day 4 of conditioning, significantly) above that of the control ...

Heart rate conditioning of anosmic rats

Physiology & Behavior, 1972
Abstract The intent of this study was to investigate the influence of the olfactory system upon heart rate changes in the rat using a classical conditioning paradigm. Normal, nerve sectioned, and lesioned animals were given 20 CS-alone trials followed by 30 conditioning trials.

Rating Transition and Default Rates Conditioned on Outlooks

The Journal of Fixed Income, 2004
Recently downgraded corporate bond issuers have different transition and default risks from recently upgraded issuers with the same ratings. Rating transition and default rates are found to be sensitive to both rating history and outlook and rate review status, when viewed in isolation.

Stimulus Exposure Rate in Verbal Conditioning

Psychological Reports, 1966
This study investigated the effects of stimulus presentation rate in a Taffel-type verbal conditioning paradigm. College Ss were required to emit sentences utilizing a verb and one of six pronouns on each of 80 stimulus cards. Rate of stimulus presentation was varied in two ways: presentation of a card every 7 sec.

The Interest Rate Conditioning Assumption [PDF]

International Journal of Central Banking, 2005
A central bank’s forecast must contain some assumption about the future path for its own policy-determined short-term interest rate. I discuss the advantages and disadvantages of the three main alternatives: (i) constant from the latest level (ii) as implicitly predicted from the yield curve (iii) chosen by the monetary policy committee (MPC) Most ...

Rate coefficients under jet conditions

Plasma Sources Science and Technology, 1998
Energy distributions obtainable when operating under jet conditions have been investigated. The related formulation of state to state rate coefficients has been worked out. The effect of varying the associated speed ratio for typical barrier and barrierless reactions is discussed by considering both model and quantum dynamics calculations.

PERSONALITY FACTORS AND RATE OF CONDITIONING

British Journal of Psychology, 1957
Sixty normal male students were conditioned, using eyeblink reflex. It was found (1) that those, students who were introverted conditioned considerably better than those who were extraverted, and (2) that there was no correlation between conditioning and neuroticism.
