Search processes in answering questions about stories: A possible model

Anderson's (1976) ACT theory was slightly modified and applied to Wh-question answering and to natural prose materials. Assuming Anderson's memory representation of sentences, the hearing or reading of a question activates the memory representations of the content words in the question. Activation fromall the content words spreads in parallel along paths linking those words and the words to the proposition node. Activation from the different content words intersects at a node. After intersection, the labels on the paths leading to the intersection are checked, and if the labels are appropriate, the answer is given. In the case of negative questions, questions whose answer is not told because the answer is not in the story, the situation is more complex. The model generated 10 predictions, for both positive and negative questions, and all predictions were supported. In line with all previous research, negative questions, collapsed over all variables, took longer to respond to than positive questions, also collapsed over all variables. This was interpreted as a more extensive search taking place with negatives.     

The perception of time in scale model environments

It has been claimed that when subjects observe differently-scaled model environments their experience of temporal duration is compressed relative to standard clock time in the same proportion as the scale of the model being observed. A series of experiments is reported in which subjects made judgements of duration while observing model environments of different scale. In each experiment, two similar model environments of different scale were presented. Three different kinds of model were used: scale model railways, sitting-room models, and abstract nonrepresentional models. Despite considerable individual variability, significant effects were obtained. Smaller scale was, up to a point, related to a compression of subjective time relative to clock time, although the effect was nowhere near as great as that previously reported. Also, when scale was reduced beyond a certain point the effect on judgements of duration was eliminated, or even reversed. It is suggested that the effect of time compression is related to differences in the density of the information to be processed in environments of different scale, and that there may be an optimum value for information density related both to the scale and to the type of environment.     

A role theoretical interpretation of personality scale item responses

This paper proposes that test-taking behavior can be regarded as a kind of self-presentation formally identical to that which goes on in most social interaction. It follows from this analysis that the success of such self-presentations should be affected by the actor's role-taking ability or empathy. Evidence is presented that supports this conjecture; the paper then suggests that role-taking ability may limit in a systematic manner validity coefficients in much assessment research.     

Positive perception: A three dimensional model and a scale

Traits and perceptions that predict psychological and physical well-being have been the focus of great interest in Positive Psychology. The paper focused on positive perception (PP) as a case in point. A three dimensional model of PP is proposed. PP represents a general tendency to evaluate positively one’s abilities, one’s past, and human nature. The construction of an 8-item self-report measure of PP, the Positive Perception Scale (PPS), is detailed. Three samples of university students and a national sample of working couples (total N = 796) helped demonstrate various psychometric aspects of the PPS. The studies confirmed the three dimensional model of PP, demonstrated it as both a trait and a state and the PPS as a valid and reliable scale, for both researchers and practitioners.     

The community alcohol use scale: A scale for use in prevention programs

The Community Alcohol Use Scale (CAUS) was developed as a continuous, reliable, valid, and acceptable measure for primary prevention studies. Items were written following a comprehensive review of the literature on alcohol dependence and alcoholism. Based upon the responses of 315 respondents to the 100-item initial version of the scale, the 45-item CAUS was developed. The CAUS was then cross-validated on a local sample (n = 274) and a provincial sample (n = 745). Estimates of internal consistency were .91, .96, and .94, respectively, for the initial and cross-validation samples. Correlations of .48 and .69 were obtained between the CAUS and the Michigan Alcohol Screening Test for the initial and local cross-validation samples. In the provincial cross-validation sample a correlation of .62 was obtained between the CAUS and the Usual Weekly Alcohol Index. Preliminary cutting scores were developed to identify those at risk for alcoholism, and alcoholics. The CAUS has potential use as an evaluative and predictive instrument in a variety of primary prevention programs.     

A FORTRAN 77 program for a nonparametric item response model: The Mokken scale analysis

A nonparametric item response theory model—the Mokken scale analysis (a stochastic elaboration of the deterministic Guttman scale)—and a computer program that performs this analysis are described. Three procedures of scaling are distinguished: a search procedure, an evaluation of the whole set of items, and an extension of an existing scale. All procedures provide a coefficient of scalability for all items that meet the criteria of the Mokken model and an item coefficient of scalability for every item. Four different types of reliability coefficient are computed both for the entire set of items and for the scalable items. A test of robustness of the found scale can be performed to analyze whether the scale is invariant across different subgroups or samples. This robustness test serves as a goodness of fit test for the established scale. The program is written in FORTRAN 77. Two versions are available, an SPSS-X procedure program (which can be used with the SPSS-X mainframe package) and a stand-alone program suitable for both mainframe and microcomputers.     

Effect of tuned parameters on an LSA multiple choice questions answering model

This article presents the current state of a work in progress, whose objective is to better understand the effects of factors that significantly influence the performance of latent semantic analysis (LSA). A difficult task, which consisted of answering (French) biology multiple choice questions, was used to test the semantic properties of the truncated singular space and to study the relative influence of the main parameters. A dedicated software was designed to fine-tune the LSA semantic space for the multiple choice questions task. With optimal parameters, the performances of our simple model were quite surprisingly equal or superior to those of seventh- and eighthgrade students. This indicates that semantic spaces were quite good despite their low dimensions and the small sizes of the training data sets. In addition, we present an original entropy global weighting of the answers’ terms for each of the multiple choice questions, which was necessary to achieve the model’s success.     

The generation effect: A meta-analytic review

The generation effect refers to the finding that subjects who generate information (e.g., produce synonyms) remember the information better than they do material that they simply read. Meta-analytic techniques were used to summarize 445 effect sizes over 86 studies, thereby assessing the magnitude and 11 potential moderators of the generation effect. The size of the generation effect across the 86 studies was .40--a benefit of almost half a standard deviation of generation over reading. The variability of the effect size due to moderator type was substantial, and we attempted to use this information to clarify several theories that have been proposed to explain the generation effect.     

The artful dodger: answering the wrong question the right way

What happens when speakers try to "dodge" a question they would rather not answer by answering a different question? In 4 studies, we show that listeners can fail to detect dodges when speakers answer similar-but objectively incorrect-questions (the "artful dodge"), a detection failure that goes hand-in-hand with a failure to rate dodgers more negatively. We propose that dodges go undetected because listeners' attention is not usually directed toward a goal of dodge detection (i.e., Is this person answering the question?) but rather toward a goal of social evaluation (i.e., Do I like this person?). Listeners were not blind to all dodge attempts, however. Dodge detection increased when listeners' attention was diverted from social goals toward determining the relevance of the speaker's answers (Study 1), when speakers answered a question egregiously dissimilar to the one asked (Study 2), and when listeners' attention was directed to the question asked by keeping it visible during speakers' answers (Study 4). We also examined the interpersonal consequences of dodge attempts: When listeners were guided to detect dodges, they rated speakers more negatively (Study 2), and listeners rated speakers who answered a similar question in a fluent manner more positively than speakers who answered the actual question but disfluently (Study 3). These results add to the literatures on both Gricean conversational norms and goal-directed attention. We discuss the practical implications of our findings in the contexts of interpersonal communication and public debates.     

The assessment of type a behaviour: A critique

Abstract

The validity of type A behaviour (TAB) as a precursor to heart disease is now increasingly subject to debate. This review examines some issues in the assessment of TAB that may have confused rather than clarified such debate. The status and interrelations between four widely used measures of TAB (Jenkins Activity Survey, Framingham Type A Scale, Bortner Rating Scale, and Structured Interview) are described, and a number of problems in their use discussed, including: differing conceptualisations of TAB, drifting criteria of assessment, failure to obtain accurate self-report of TAB, and difficulties associated with the measurement of TAB in populations other than male non-manual workers. Future research should attempt to obviate such difficulties, while elucidating pathogenic behaviours and attitudes, and how these interact with other variables to increase the risk of heart disease. Finally, the value of a state measure of TAB is discussed.

The family of origin scale: A construct validation study

Data from 69 women and 63 men along with ratings from a panel of expert judges were used to assess the construct validity of the Family Of Origin Scale as a measure of family health. Loevinger's conception of construct validity, focusing on the substantive, structural, and external components of validity, was employed to organize the research procedures followed and the data analytic techniques used. Results showed that the instrument appears to be a useful measure of a warmth-coldness affect dimension in the family of origin, but the multi-dimensional structure of the test, as a measure of family-of-origin health, could not be validated. Suggestions for use, score interpretation, and further development are discussed.     

Neural correlates of feigned memory impairment are distinguishable from answering randomly and answering incorrectly: an fMRI and behavioral study

Previous functional magnetic resonance imaging (fMRI) studies have identified activation in the prefrontal-parietal-sub-cortical circuit during feigned memory impairment when comparing with truthful telling. Here, we used fMRI to determine whether neural activity can differentiate between answering correctly, answering randomly, answering incorrectly, and feigned memory impairment. In this study, 12 healthy subjects underwent block-design fMRI while they performed digit task of forced-choice format under four conditions: answering correctly, answering randomly, answering incorrectly, and simulated feigned memory impairment. There were three main results. First, six areas, including the left prefrontal cortex, the left superior temporal lobe, the right postcentral gyrus, the right superior parietal cortex, the right superior occipital cortex, and the right putamen, were significantly modulated by condition type. Second, for some areas, including the right superior parietal cortex, the right postcentral gyrus, the right superior occipital cortex, and the right putamen, brain activity was significantly greater in feigned memory impairment than answering randomly. Third, for the areas including the left prefrontal cortex and the right putamen, brain activity was significantly greater in feigned memory impairment than answering incorrectly. In contrast, for the left superior temporal lobe, brain activity was significantly greater in answering incorrectly than feigned memory impairment. The results suggest that neural correlates of feigned memory impairment are distinguishable from answering randomly and answering incorrectly in healthy subjects.     

Type A behavior and emotional responses to uncertainty: A test of the self-appraisal model

The self-appraisal model of Type A behavior holds that Type A's desire an accurate appraisal of abilities, and respond to uncertainty about abilities with exaggerated attempts to generate diagnostic information. The model also predicts that the major emotional response to uncertainty for Type A's is anxiety. In this study, Type A's and B's were induced to succeed or fail on a task where they were either very certain or very uncertain of their subsequent ability levels. Task failure produced greater depression, anger, and frustration for all subjects. Consistent with the self-appraisal model's prediction, uncertainty (regardless of success or failure) led to greater anxiety for Type A's than for Type B's. In fact, greater uncertainty produced lower anxiety for Type B's, indicating that Type A's and B's differ dramatically in their emotional responses to uncertainty about abilities.     

Scaling questions: asking and answering them in counselling1

Solution-focused counsellors use “scaling questions” to construct understandings of clients’ concerns and solutions to them. We examine how these questions are asked and answered, offering evidence of what is constructed from within counselling discourse. Also, clients and counsellors offer their retrospective accounts of their participation in question and answer sequences in their dialogues. We conclude by speaking to the implications we see from this research as it relates to collaborative and resourceful dialogue between counsellors and clients.
