Recall of aggressive and withdrawn statements among young children: Social schema or meaningfulness

Two studies assessed the effects of type of sentence (aggressive vs. withdrawn) and meaningfulness level on the sentence recall of young children. In Study 1, normative data showed that the meaningfulness value of aggressive sentences was greater than that of withdrawn sentences and that meaningfulness and recall were positively related. In Study 2, subjects were tested for sentence recall in a 2 (aggressive vs. withdrawn sentences) x 2 (high vs. low meaningfulness)within subjects design. The sole significant effect was meaningfulness, with the superior recall of high relative to low meaningful sentences. Results are interpreted through a knowledge base model. This research was supported by the Wake Forest University Research and Publication Fund. Experiment 1 was presented at the 1988 annual meeting of the American Psychological Association, Atlanta, GA, and Experiment 2 was presented at the 1991 annual meeting of the American Psychological Society, Washington, DC.

Incompatibility statements

In the context of worlds with infinitely many bearers of utility, we argue that several collections of natural Utilitarian principles--principles which are certainly true in the classical finite Utilitarian context and which any Utilitarian would find appealing--are inconsistent.     

Linguistic factors and meaningfulness of personal constructs

Studied the effect of linguistic development and social appropriateness of a language upon the meaningfulness of personal constructs articulated in this language. Subjects were 60 bilingual pupils from a boys secondary school in Tanzania. Linguistic development was manipulated by choosing pupils who had either 1½ years or 3½ years experience of instruction in English. For each subject constructs were elicited and grids administered in both English and Swahili. Two types of elements were used, for one of which Swahili was the socially more appropriate language and for the other, English. Results from the study indicate that rating polarization is a function of both linguistic development and appropriateness of language for construing the domain in question. These results are therefore interpreted as indicating that meaningfulness of personal constructs, as indicated by rating polarization, can have linguistic determinants.     

Effect of meaningfulness on judgments of computability

The University of Michigan, Ann Arbor, Michigan 48104 After memorizing a set. of four equations, subjects were given problem frames specifying an unknown variable and two, three, or four given variables. The task on each item was to judge whether the presented variables corresponded to a problem that could be computed. (No values were given and no computation was carried out.) The main finding was a strong interaction: With formulas consisting of uninterpreted letters, judgments of uncomputable items were much slower than judgments of computable items; however, the difference between positive and negative items was much smaller when formulas consisted of meaningful concepts. Attempts to remove the interaction by presenting the nonsense formulas as an integrated network or by using a format allowing easy chunking of the variables in each formula did not succeed. At this point it appears most promising to investigate effects of meaningfulness on basic component processes, such as decisions about whether pairs of items come from the same formula.     

Empirical tests of scientific realism: A quantitative framework

The scientific realism debate in philosophy of science raises some intriguing methodological issues. Scientific realism posits a link between a scientific theory's observational and referential success. This opens the possibility of testing the thesis empirically, by searching for evidence of such a link in the record of theories put forward in the history of science. Many realist philosophers working today propose case study methodology as a way of carrying out such a test. This article argues that a qualitative method such as case study methodology is not adequate for this purpose, for two reasons: to test scientific realism is to pose an effects-of-causes question, and observational and referential success are quantities that theories possess to a greater or lesser degree. The article concludes that an empirical test of scientific realism requires a quantitative method.     

Applications of the theory of meaningfulness to psychology

The theory of meaningfulness of statements using numerical scales is summarized. Applications of this theory are surveyed. These deal with average performance, importance ratings, statistical tests, indices of consumer confidence, psychophysical scaling, block modeling of social structure, structural modeling in decision making, and the analysis of order and matching experiments.
