Novelty-seeking,novelty-finding,and the developmental continuity of intelligence

This article suggests that novelty-seeking and novelty-finding, as well as the ability to learn and reason with novel kinds of concepts, are critical aspects of intelligence at all ages from infancy, onward. The results of studies by Lewis and Brooks-Gunn and by Fagan and McGrath regarding intelligence in infancy are reviewed, and these results are found to be compatible with some of my own results regarding intelligence in adulthood. It is suggested that a major aspect of intelligence, attitude toward and performance with novel kinds of concepts, is continuous in nature throughout the life span, although by necessity, they must be measured in different ways at different times of life.     

Isolating the components of intelligence

In a recent volume (Sternberg, 1977b), I proposed a method called componential analysis that provides a means to isolate the components of intelligent performance. The method was described in detail, and then tested in a series of experiments. But an important question was left unanswered by this early work: Is componential analysis generalizable to tasks other than analogies? More recently, I have been investigating the generalization of the methodology to other tasks, and have also been engaged in extending the methodology in order to increase its flexibility of application. The present article (a) briefly summarizes the structure of a componential analysis, (b) describes the method of precuing, the method originally used for isolating the components of intelligence, and (c) describes new methods that have also been successful in isolating these components in a variety of reasoning tasks.     

The case of the disappearing disagreements: A reply to Yussen

S. R. Yussen (1984, Developmental Review, 4, 139–144) and I have few disagreements. The major one seems to be in what the purpose of my article (R. J. Sternberg, 1984, Developmental Review, 4, 113–138) should have been. I believe the article fulfills my own purpose, if not Yussen's.     

Developmental patterns in the encoding and combination of logical connectives

A total of 224 subjects in grades 2, 4, 6, 8, high school, and college solved problems requiring comprehension of the logical connectives and, or, if-then, only if, and if and only if, as well as the terms is and is not. Half the subjects were required merely to encode the connectives; the other half were required to combine as well as encode them. Problems were presented in two replications (over two sessions) via two different content vehicles. Quantitative analyses revealed significant effects of task, age, session, and connective, with comprehension of different connectives developing at different rates. In general, comprehension of the conjunctive connective was easiest; comprehension of the conditional and biconditional connectives was most difficult. Qualitative analyses indicated just how the logical connectives were interpreted at each grade level, and also investigated individual differences within each grade level.     

Natural, unnatural, and supernatural concepts

Five experiments investigating information-processing consequences of concept naturalness and unnaturalness are reported. In particular, an attempt is made to examine the separate and joint effects of simplicity and entrenchment upon reasoning with natural and unnatural concepts. The experiments employed four variants of a concept-selection task in which subjects characterized the state of an object at some future time on the basis of information about the object at that time and at some earlier time. In all five experiments, both simplicity and entrenchment affected ease of information processing. The last two experiments showed that the effect of simplicity was greater than that of entrenchment. An informationprocessing model of task performance provided a very good account of the latency and error data. Scores from the concept-selection task correlated with scores from a set of psychometric inductive-reasoning tests; indeed, the correlations were higher than those usually found between cognitive task performance and psychometrically measured intelligence. Processing of nonentrenched concepts may provide a useful means for studying the nature of intelligent performance.     

The development of analogical reasoning processes.

Two experiments were conducted to test the generalizability to children of a theory of analogical reasoning processes originally proposed for adults (R. J. Sternberg, Psychological Review, 1977a, 84, 353–378; R. J. Sternberg, Intelligence, information processing, and analogical reasoning: The componential analysis of human abilities, Hillsdale, N.J.: Lawrence Erlbaum Associates, 1977b) and to examine the development of analogical reasoning processes in terms of five proposed sources of cognitive development: (a) availability of component operations; (b) strategy for combining multiple component operation; (c) strategy for combining multiple executions of the same component operation; (d) consistency in use of strategy; (e) component-operation latency and difficulty. Between 15 and 21 subjects in each of grades 2, 4, 6, and adulthood (ages 8, 10, 12, and 19 years, respectively) were tested in their ability to solve analogies of systematically varied difficulty. Performance was measured in terms of latencies for items solved correctly, latencies for all items solved, and error rates. A slightly modified version of the Stenberg, 1977(a), Stenberg, 1977(b) theory was found to be applicable to the data for each of the age levels tested. In analogies with perceptually separable attributes, change over age was found in sources (d) and (e) noted above. In analogies with perceptually integral attributes, change over age was found in sources (a), (c), (d), and (e). Developmental trends were discussed in terms of past theory and findings, and possible reasons for differences in developmental patterns between the two kinds of analogies were suggested.     

A transitive-chain theory of syllogistic reasoning

A new theory of syllogistic reasoning, called the transitive-chain theory, is presented. The transitive-chain theory proposes that information about set relations is represented in memory by pairs of informational components. The theory further proposes that information about set relations is integrated by applying a small set of rules to transitive chains of these set relations. The rules that are applied to these chains are specified in detail. The theory is cast in terms of information-processing models for variants of the syllogistic reasoning task, and then mathematical models that quantify each of these information-processing models are presented. In a series of five experiments, the transitive-chain theory provides a good account of the response-choice data for syllogisms with various types of content, quantifiers, and logical relations (categorical and conditional). The results of these experiments offer tentative answers to four issues in the theory of syllogistic reasoning: (a) representation of premise information; (b) combination of premise information; (c) sources of difficulty in syllogistic reasoning; and (d) generality of the processes used in syllogistic reasoning.     

Aptness in metaphor

We propose that in understanding a metaphor, an individual sees a concept from one class or domain in terms of its similarity in two different respects to a concept from another class or domain. The two kinds of similarity are within-domain similarity, or the degree to which two concepts occupy similar positions with respect to their own class or domain; and between-domain similarity, or the degree to which the classes or domains occupied by the concepts are themselves similar. To test this dual notion of similarity, we obtained ratings of the aptness of 64 metaphors from one group of subjects and ratings of their comprehensibility from another group of subjects. The terms of the metaphors had been scaled (based on the ratings of pretest subjects) to give measures of distance both within and between domains. Aptness of metaphors related positively to betweendomain distance, negatively to within-domain distance, and not at all to overall distance. Metaphors are thus perceived as more apt to the extent that their terms occupy similar positions within domains that are not very similar to each other. Comprehensibility also related to aptness. In a second experiment, subjects ranked a set of terms as possible completions for metaphors. For both groups of subjects in this experiment, the rank of an alternative's within-domain distance correlated with its relative popularity. Quantitative models, patterned after a model proposed by D. Rumelhart and A. A. Abrahamson (Cognitive Psychology, 1973, 5, 1–28) for analogical reasoning, afforded significant prediction of the choices of the group of subjects in which all the possible completions of a metaphor were from a single domain. The same models did not predict the choices of a group of subjects in which the possible completions of the metaphors were from different domains.     

Understanding and appreciating metaphors

We consider three theories that have dominated discussions of metaphor. One view is that metaphors make comparisons, the basis for the comparison being the features (or categories) that the terms of the metaphor share. The second view is that metaphors involve an anomaly. The third view is that metaphors are ‘interactive’, producing a new way of seeing the terms. We propose a new theory—the domains-interaction view—that draws on elements of all three earlier views, but borrows especially from the interaction view. We consider the implications of our theory for three questions: What are metaphors? How are they understood? What makes a good metaphor? We argue that metaphors correlate two systems of concepts from different domains. The best metaphors involve two diverse domains (more distance between domains making for better metaphors) and close correspondence between the terms within those domains. We call the degree of correspondence within-domain similarity. Metaphors are interpreted in several stages: the terms of the metaphor are encoded; the domains involved are inferred; the structures to be seen as parallel are found; the correspondences between these structures are ‘mapped’ or constructed; the terms of the metaphor are compared. If the terms are not seen to match or occupy analogous roles in their different domains, then the metaphor may be reinterpreted. The evidence on all this is tentative but supports our view. We review two studies (Tourangeau and Sternberg, 1981) that support the hypothesis that distance within domain relates negatively to aptness, whereas distance between domains relates positively. Several studies on comprehension tend to disconfirm the comparison theory's notion that the tenor and vehicle necessarily share features. Tenor and vehicle also appear to have asymmetrical roles in the interpretive process.     

Recovery of the US representation over time during extinction

Four experiments used a conditioned suppression procedure in rats to explore changes in the US representation over time during the course of extinction. They employed two previously reported effects: reinstatement of responding to an extinguished CS by separate US presentation, and the erasure of that effect by interposed nonreinforcement of a second excitatory CS. These effects have been interpreted as enhancing and depressing the US representation, respectively. Experiment 1 found the erasing effect to decrease but still to remain substantial after over a 4-day period, suggesting a partial recovery with time of a deliberately depressed US representation. Experiment 2 implicated this change as a contributor to the phenomenon of spontaneous recovery by showing that recovery to be sensitive to erasure effects. Experiments 3 and 4 found evidence for an interaction between the state of the US representation and the amount of associative change which results from nonreinforcement of an excitatory CS. When the US representation was strong, either because of reinstatement or the passage of time, nonreinforcement of a CS was especially effective in producing associative change. When the US representation had been depressed by erasure, those nonreinforcements produced relatively less associative loss. Moreover, these effects upon associations were reasonably stable in the sense that they left asymptotic differences in the strength of associations after extinction. Together with previous findings, these results point to an important role for the US representation in the performance and learning which occurs during extinction.     

The extinction of within-compound flavor associations

Three experiments studied extinction of the associations which are formed between two flavors presented in a simultaneous compound. In Experiment 1 those associations were identified by a sensory preconditioning procedure in which the poisoning of one element of the compound led to the rejection of the other element. Separate presentation of either element between their joint occurence and the poisoning of one element sharply attenuated the rejection of the other element. That attenuation was interpreted in terms of the extinction of within-compound associations. Experiment 2 obtained similar results with an alternative extinction procedure in which the elements of the original compound were presented in other compounds. Experiment 3 obtained similar results when the existence of the within-compound associations was determined by an alternative assessment procedure in which one element of the compound was made more attractive by the induction of a specific hunger. These experiments suggest that within-compound associations can be extinguished when the elements are separately presented outside of the compound. Experiments 2 and 3 make less plausible an alternative interpretation of the effects of separate element presentation in terms of reduction of the novelty of the element. The findings may be taken as implying that the elements of a simultaneously presented compound are joined by a single symmetrical association which acts at various points during a sensory preconditioning experiment.     

A triarchic theory of intellectual development during adulthood

A triarchic theory of intellectual development during adulthood is proposed. The theory comprises three parts: a contextual part that emphasizes the role of intelligence in successful adaptation to the environment; a componential part that specifies the mental mechanisms and processes underlying intelligent behavior; and an experiential part that indicates that intelligence is best manifested in instances in which the task or situation requiring the application of these processes is relatively novel or is becoming automatized. A selective and brief review of the literature on adult intellectual development is provided as evidence for the triarchic theory. The triarchic theory is then compared with four other theoretical approaches to adult intellectual development. It is argued that the triarchic theory provides new insights regarding the ways in which intelligence changes from early to middle to late adulthood and suggests certain properties of tasks and situations that make them more or less useful as measures of intelligence at various points in adult intellectual development.     

Components of syllogistic reasoning

The present research sought to understand the components of syllogistic reasoning used in a syllogistic evaluation task. In this task, subjects must indicate whether a conclusion such as “Some Yale professors are humbugs” is definitely true, or never true of a set of premises such as “Some humbugs study syllogistic reasoning; some Yale professors study syllogistic reasoning”. A modified form of componential analysis (Sternberg 1977, 1978) was used to decompose the syllogistic evaluation task with abstract content into encoding and encoding plus combination subtasks. The response-choice data from these subtasks were used to provide (a) direct tests of a proposed theory of syllogistic reasoning, and in particular, of its assumptions about sources of error in syllogistic reasoning; and (b) direct inferences regarding the representation of relations between the subject and predicate of the premises as encoded and combined. The results supported a proposed transitive-chain model of syllogistic reasoning.     

Intervention and sleeper effects: A reply to Clarke and Clarke

The evolution of the concept of “sleeper effects” is traced from the work of C. I. Hovland, A. A. Lumsdaine, and F. D. Sheffield, Experiments on Mass Communication. Princeton, N.J.: Princeton Univ. Press, 1949, to the present time. The concept originally referred to the delayed emergence of attitude change in persuasibility research. It has also been used in developmental investigations, with attendant theoretical problems that have not been fully addressed. These problems are examined, with the recommendation that the social psychologist's sleeper effect should be modified to meet developmental needs and renamed “delayed treatment effects”. Such effects are highly relevant to recent findings from studies of early childhood intervention programs.     

Sequencing in social repair: A Markov grammar of children's discourse about transgressions

A Markov grammar was developed to account for the sequence of conversational moves in discourse about transgressions. This discourse interrupts ongoing activity and functions to repair the social fabric when inappropriate or awkward behavior has attracted the attention of interactants. A corpus of 1248 such interchanges, obtained in 90 hr of observation in kindergarten through fourth grade classrooms, was the basis of the grammar. Beginning with theoretical assumptions about the canonical form of these interchanges, the process of grammar development was explicitly described and the direction given by pragmatic considerations (such as attaining a balance between parsimony and accuracy) was discussed. The resultant grammar accounted for 83% of the corpus and served as a framework within which age and context effects on the discourse were explored. Loglinear analyses of multiway contingency tables at each transition point in the grammar revealed that the presence vs absence of an adult in the interchange affected the relative preferences for different alternatives at one juncture, but that subjects' ages did not influence the sequencing of discourse as described by the model. The overall approach was considered in relation to the more traditional uses of Markov models and its strengths, weaknesses, and future promise for discourse analysis were discussed.     

Self- and other regulation during the infancy period

The “other regulation” views of Lev Vygotsky and of Jerome Bruner are contrasted with Jean Piaget's self-regulatory model of infant development. Examples of adult behavior in Piaget's writings and in mother-infant interactions suggest that adults perform behaviors which are analogous to Piaget's type a and b self-regulation. Data from infant games are provided to illustrate the processes by which mothers regulate the environments for their infants and the consequences of such maternal regulation for infant development.     

Within-compound associations in a variety of compound conditioning procedures

Three experiments used a flavor-aversion preparation to demonstrate the occurrence of within-compound associations in various conditioning procedures. In Experiment 1 rats first received two separate two-flavor compounds, each followed by a mild US. They then received one element from one compound paired with a strong US and one element from the other compound nonreinforced. A subsequent choice test of the other two flavors from the compounds revealed that the consumption of each test flavor reflected the conditioning history of the element with which it had been paired. Rats drank less of the flavor whose associate had been paired with the strong US than of the flavor whose associate had been nonreinforced. In Experiment 2 within-compound associations were observed using a similar design in a blocking procedure in which one element from each of the two compounds was conditioned previously. Experiment 3 identified within-compound associations in a procedure where reinforced single element presentations were intermixed with nonreinforced compound presentations, as in a conditioned inhibition paradigm. These results suggest that within-compound associations occur in several important conditioning procedures which use multiple CS presentations.     

Some attributes of adjectives used by young children

Analysis of 24 spontaneous speech samples from children at 24 and 30 months revealed a correlated progression in the form, function and meaning of modifiers used with increased language development. Predicate adjectives were used to comment on transitory states of objects and predominated in the early speech samples. Attributive adjectives were used to subdivide classes or to specify among particular instances within classes on the basis of physical characteristics such as size, by use of a conventional type name, or by use of a possessive. Attributives predominated in the later speech samples. Differential use of a particular form appears to be a function of its cognitive and communicational usefulness rather than its syntactic derivation.
