Analysis of certified public accounting subgroup and accounting student personality traits using the California Psychological Inventory

Samples of 56 male certified public accounting firm employees and 24 male accounting undergraduate students were given the CPI to test for subgroup differences in personality traits. The samples were also compared with eight occupational groups reported in the CPI manual. A statistical analysis of CPI scale mean score differences indicates a dichotomy of the accounting sample with the older accountants more conservative, conforming and restrictive than the younger accountants.     

Conservatism as a function of bag composition

The first purpose of this bookbag and pokerchip experiment was to examine the influence of the sample size and the relative frequency of the red chips in the sample on the amount of conservatism. The second purpose was to replicate the results of DE SWART (1972), and to test his hypothesis that the slope B of the function: log Φ(T)=A+B(r−b), is linearly related to log [p_r/(1−p_r)], where p_r represents the bag composition.     

Reinforcement and response rate interaction in multiple random-interval avoidance schedules

Two experiments were conducted to investigate the interaction between response rate and reinforcement frequency in multiple random-interval avoidance schedules. Responses cancelled delivery of shocks that could be scheduled at different random intervals in each component. When shock-frequency reduction was taken as the measure of reinforcement, the relationship between response rate and frequency of reinforcement was described by the same equations used by Herrnstein (1970) to describe responding with positive reinforcement.     

On the development of national attitudes in children

The present study consists of three related experiments which are concerned with the development of national attitudes in children between the ages of seven and twelve. It was predicted on the basis of a structural interpretation of Allport's three-stage developmental theory of prejudice that national attitudes will increase at first due to increasing consistency of judgment and decrease afterwards due to cognitive differentiation. The hypothesis is partially confirmed with respect to the attitudes of children towards other countries but not confirmed with respect to the attitudes of children towards people who are perceived as foreigners. A tentative explanation is offered for the last finding. It was shown moreover that the attitudes of older children display more cognitive balance than those of younger children. In connection with the last problem, a quantified modification Bf Heider's theory of balanced states was introduced.     

Classical conditioning and extinction of human systolic blood pressure

Fifty-five male and female undergraduates underwent 3 sessions of conditioning and one of extinction. Shock (UCS) occurred intermittently during light-on (CS+) and never in light-off (CS-). Results showed that (1) pressure in CS+ was significantly higher than CS-throughout all sessions; (2) within session adaptation was significantly retarded while incoming pressure levels did not adapt across sessions; (3) conditioned effects persisted 6 months after the last shock session; (4) verbal information as to non-appearance of shock significantly dropped pressure levels and reduced the discriminative light effect; (5) the post-shock unconditioned pressure response was a peak rise at 52 seconds, then a decrease which stabilized to the pre-shock level at 2 minutes. Pavlovian control of blood pressure was demonstrated and the present methodology offers an explicit procedure for further laboratory exploration.     

Cross-domain semantic priming in normal subjects and a prosopagnosic patient

Cross-domain semantic priming of person recognition (from face primes to name targets at 500msecs SOA) is investigated in normal subjects and a brain-injured patient (PH) with a very severe impairment of overt face recognition ability. Experiment 1 demonstrates equivalent semantic priming effects for normal subjects from face primes to name targets (cross-domain priming) and from name primes to name targets (within-domain priming). Experiment 2 demonstrates cross-domain semantic priming effects from face primes that PH cannot recognize overtly. Experiment 3 shows that cross-domain semantic priming effects can be found for normal subjects when target names are repeated across all conditions. This (repeated targets) method is then used in Experiment 4 to establish that PH shows equivalent semantic priming to normal subjects from face primes which he is very poor at identifying overtly and from name primes which he can identify overtly. These findings demonstrate that automatic aspects of face recognition can remain intact even when all sense of overt recognition has been lost.
