Reward Effects

30 rats were trained in a runway for 16 days at 5 trials a day. During acquisition (10 days) Ss were trained on an irregular 50% partially delayed reward schedule. The duration of delay was 30 sec. and 2 pellets of reward were given on all delayed trials. The magnitude of immediate reward was varied over three levels (2, 10, 24 pellets) as a between-groups factor. Although the larger rewards developed somewhat faster acquisition speeds than the small reward the results did not reach statistical reliability. During extinction, however, the larger magnitudes of reward significantly increased resistance to extinction. These results were discussed in terms of aftereffects, frustration, and dissonance theories of extinction.

Delayed Reward

A greater proportion of children as young as 5 yr. of age preferred a delayed-large as opposed to an immediate-small reward. In addition, decision latencies of Ss preferring immediate reward were significantly shorter than of those who chose delayed reward. These results support the hypothesis that age as a determinant of preference for delayed reward is confounded with a number of other variables such as reward values and duration of delay intervals and that other individual difference variables may also be associated with preferences.

Basic Hypothesis

The paper focuses on the topic of intertemporal discounting of individuals according to age groups. Using the sample of examined individuals, it aims to verify the hypothesis that the patience of individuals decreases with their increasing age. The study included a total of 599 individuals with an average age of 38.3 years (min. 16 and max. 82 years) who answered classical questions focused on time discounting and impulsive behaviour. In total, four possible scenarios were analysed: a small reward (CZK 100) with a delay of 1 day, a small reward with a delay of 1 month, a large reward (CZK 100,000) with a delay of 1 day and a large reward with a delay of 1 month. The delayed reward was always increased by 10% (i.e., CZK 110 or CZK 110,000). The basic hypothesis was that with increasing age, the subjective discount rate increases i.e., patience decreases. The above-mentioned 4 scenarios were evaluated for the hypotheses, while only three of the four scenarios were confirmed for all hypotheses. The results in the examined individuals suggest that with increasing age, there is a decrease in patience and at the same time a decrease in impulsive behaviour. These findings may have an overlap in consumption or savings in relation to the aging population.

Reinforcement Procedure

2 varied magnitude of reward instrumental runway studies with rats were conducted to ascertain whether the sequential variables, intertrial reinforcements and number of successive small magnitude of reward trials (S-length) would influence resistance to extinction (Rn) in a manner similar to that of comparable variables in the partial reinforcement (PR) situation. Exp. I indicated that S-length affects Rn in the same manner as the number of consecutive nonreinforced trials in the PR experiment. Contrary to the results of PR experiments, in Exps. I and II, the intertrial reinforcement procedure did not reduce Rn. The results of the two experiments indicate, however, that animals receiving identical goal events but differing in the sequence of such events exhibit differential Rn.

Opposite Sequence

Rats were tested in an alley to determine the effect of reward sequence on the extinction and spontaneous recovery of latency and time. Daily, half of the Ss received a small reward on Trial 1 and a large reward on Trial 2 (SL), while the other half received the opposite sequence of rewards (LS). Resistance to extinction and spontaneous recovery were greater when a large reward fallowed a small reward than when a small reward followed a large reward. The results were discussed in terms of Capaldi's (1967) sequential learning hypothesis.
