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.     

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.     

Adults' conceptions of intelligence across the adult life span.

To examine whether young, middle-aged, and older adults view the concept of intelligent person as similar or different during adulthood, 140 adults of various ages rated how likely it would be for individuals of average and exceptional intelligence at 30, 50, and 70 years of age to be engaged in behaviors previously identified by adults as characterizing adult intelligence. Adults perceived more similarity between exceptionally intelligent prototypes of closer ages (i.e., 30 and 50 and 50 and 70). Intelligence was perceived to consist of interest and ability to deal with novelty, everyday competence, and verbal competence--dimensions that were perceived to be differentially important for different-aged prototypes and by individuals of different ages. Participants' conceptions also included the idea that intelligence is malleable and that abilities differentially increase or decrease across the life span.     

Perceived fraudulence in young adults: is there an "imposter syndrome"?

This investigation consists of two studies designed to examine perceived fraudulence, its measurement, and the personality traits associated with the experience in young adults. For Study 1, the Perceived Fraudulence Scale (PFS), a new measure constructed for this study, was administered to a sample of 50 college undergraduates, along with several other self-report measures; a semistructured interview and thought-listing exercise were added to provide convergent assessments of perceived fraudulence. Correlational patterns and regression analyses supported the investigators' conceptualization of perceived fraudulence as involving a combination of fraudulent ideation, depressive tendencies, self-criticism, social anxiety, achievement pressures, and self-monitoring skills. Study 2, in which 100 college undergraduates completed several personality questionnaires, replicated the factor structure of the PFS and provided some evidence for the discriminant validity of the construct of perceived fraudulence.     

When will the milk spoil? Everyday induction in human intelligence

We sought to understand (a) the mental processes underlying everyday predictive and postdictive judgements involving objects undergoing either change or no change of state over time and (b) the relation of these processes to intelligence. Forty adult (nonstudent) participants were asked to solve 40 induction problems, each presented in four forms, for a total of 160 test items. Half of the items involved predictions and half involved postdictions; within each of these two categories, half of the items involved a state change from present to future (prediction) or past (postdiction), and half did not. In addition, each participant completed convergent-discriminant psychometric ability tests measuring inductive reasoning, deductive reasoning, and vocabulary.Prediction was performed more rapidly than postdiction, but was also more susceptible to errors of judgement. Judgements involving change of state were more rapid and less error-prone than were judgements involving no change. A single information-processing model was useful for describing performance on both prediction and postdiction problems. A quantification of stimulus variables affecting performance via this model (with six predictor variables) provided a good account of participants' response latencies. Response latencies showed convergent and discriminant validity, exhibiting rather high correlations with inductive reasoning, but not with deductive reasoning. The paradigm we used thus seems to provide one useful approach to understanding the relationship of everyday induction to human intelligence, and to provide a complement to the more abstract kinds of problems—such as analogies, classifications, series completion, and matrix problems—typically used to test inductive-reasoning abilities, as an aspect of intelligence.     

The effects of divorce and custody arrangements on children's behaviour, development and adjustment

A group of experts from developmental and clinical psychology, sociology,social welfare, and law met at a conference centre in Middleburg, Virginiaon December 1-4, 1994, under the sponsorship of the U.S. National Instituteof Child Health and Human Development. The group's mandate was to evaluateexisting knowledge regarding the ways in which children are affected bydivorce and the varying custody arrangements that follow it. Many of thediscussions also addressed the ways in which the adverse effects of divorcemight be ameliorated by changes in policy or practice. This documentrepresents a statement co-signed by most of the participants summarizingareas of agreement regarding the current status of knowledge in this areaand outlining topics in need of further research. The report is designed toguide various legislatures, the judiciary, the bar, and the various mentalhealth professionals who are involved in counselling or educating familiesexperiencing separation or divorce, as well as those who mediate oradjudicate the disputes regarding the custody of minor children. Thepreliminary draft of this consensus document was prepared by Michael E. Lamband Kathleen J. Sternberg following the three-day conference, withadditional redrafting by Ross A. Thompson. The draft was reviewed andrevised by the other participants over the ensuing months. This report,revised in accordance with the participants' comments, is a product of this process.     

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.     

A comparison of mental and physical context reinstatement in forensic interviews with alleged victims of sexual abuse

Forensic interviews with 142 alleged victims of sexual abuse, ranging from 4.0 to 13.5 years of age, were conducted under three different interviewing conditions: at the scene of the incidents (Physical Context Reinstatement; PCR group), in the investigator's office with mental context reinstating instructions (MCR group), and in the office without contextual cueing (Control group). Children in the PCR, MCR, and Control groups did not differ significantly with respect to the total number of informative details reported. Children in the MCR condition provided more detailed responses to the main invitation and in their first narrative than did children in the PCR condition, however. They also provided proportionally more detailed responses to open‐ended invitations and fewer details in response to directive prompts than did children in the two other conditions. The MCR procedures were thus associated with greater improvements in the quality of information retrieval than were the PCR procedures. In all interviewing conditions, children aged 7 to 13 years provided significantly more details than 4‐ to‐6‐year‐old children did. The youngest children provided fewer details in response to invitations and directive utterances, and proportionally more details in response to option‐posing and suggestive utterances. No significant interactions between age and interviewing condition were apparent. Published in 2002 by John Wiley & Sons, Ltd.     

Organizational culture, creative behavior, and information and communication technology (ICT) usage: a facet analysis.

Despite the prominence of organizational culture (OC), this concept is controversial and its structure has yet to be systematically analyzed. This study develops a three-pronged formal definitional framework on the basis of facet theory (FT) and explores behavior modality, referent, and object. This facet analysis (FA) of OC accounts successfully for variation in both creative behavior at work and the usage of information and communication technologies (ICTs). An analysis of data collected from 230 employees in the financial industry indicates that a radex structure was obtained for work and ICT. The behavior modality facet ordered the space from center to periphery, and referents facet relates to the direction angles away from the origin.
