AGE AND BEHAVIOR: LEARNING AND PERFORMANCE - TASK MEANINGFULNESS - PERSONAL RELEVANCE AND TASK DIFFICULTY
The opinion that older people are disadvantaged when the laboratory task is not relevant is not unlike the common opinions regarding motivation, i.e., old people are presumed to be less involved than younger adults with the laboratory task. It was just seen that data are available to indicate just the opposite—elderly adults may be more involved than younger adults.
The tie between involvement in the task and the meaningfulness of the task was seen in at least three studies. Two of these do not involve learning, but the third does. The two studies not of learning serve to point out that autonomic arousal as measured by FFA determination, for example, and suppressed by the drug, Propranolol, discussed previously, may not be the same as "involvement in laboratory situations" which are meaningful and relevant to the subject. It would seem that in the case of autonomic arousal the personal involvement is general and undifferentiated; in the case of relevant material, the personal involvement is specific to the task at hand.
In the first of the two studies, Shmavonian and Busse (1963) measured galvanic skin responses (GSRs) which were spontaneously emitted in the context of various types of stimulation. These GSRs, like the FFAs, were thought to be reflective of states of arousal on the part of the subject. Older men (60-70 years) emitted fewer of these GSRs than younger men (20-24 years) and were thus thought to be less involved in the laboratory situation, not more. This age comparison, however, was made with stimuli of simple tones; when the same comparison was made with meaningful spoken phrases, the differences between age groups in the GSRs were much diminished, although they did not disappear altogether. The implication was that the older people were disproportionately less involved in the laboratory task when it was less meaningful to them.
The second study will be discussed very briefly because it was reviewed in detail in the previous chapter dealing with problem solving and concept formation. Arenberg (1968) presented tasks that required the identification of concepts by logical analysis. Arenberg provided information based upon the abstract dimensions of color, form, and number, with the intent of monitoring the pattern of solution strategies. He found that the older subjects had so much difficulty with this task that many could not even understand what was required. When, however, Arenberg translated the abstract information to concrete meaningful terms ("poisoned foods" in this case) his results were very different.
The old subjects could understand what to do and solved many of the problems, although their overall performances were not at the same level as those of the young subjects.
