Relevance-driven information search in "pseudodiagnostic" reasoning

When faced with two competing hypotheses, people sometimes prefer to look at multiple sources of information in support of one hypothesis rather than to establish the diagnostic value of a single piece of information for the two hypotheses. This is termed pseudodiagnostic reasoning and has often been understood to reflect, among other things, poor information search strategies. Past research suggests that diagnostic reasoning may be more easily fostered when participants seek data to help in the selection of one of two competing courses of action as opposed to situations where they seek data to help infer which of two competing hypotheses is true. In the experiment reported here, we provide the first empirical evidence demonstrating that manipulating the relevance of the feature for which participants initially receive information determines whether they will make a nominally diagnostic or pseudodiagnostic selection. The discussion of these findings focuses on implications for the ability to engage in diagnostic hypothesis testing.     

Testing parameters in structural equation modeling: every "one" matters

A problem with standard errors estimated by many structural equation modeling programs is described. In such programs, a parameter's standard error is sensitive to how the model is identified (i.e., how scale is set). Alternative but equivalent ways to identify a model may yield different standard errors, and hence different Z tests for a parameter, even though the identifications produce the same overall model fit. This lack of invariance due to model identification creates the possibility that different analysts may reach different conclusions about a parameter's significance level even though they test equivalent models on the same data. The authors suggest that parameters be tested for statistical significance through the likelihood ratio test, which is invariant to the identification choice.     

"Proper" Binormal ROC Curves: Theory and Maximum-Likelihood Estimation

The conventional binormal model, which assumes that a pair of latent normal decision-variable distributions underlies ROC data, has been used successfully for many years to fit smooth ROC curves. However, if the conventional binormal model is used for small data sets or ordinal-category data with poorly allocated category boundaries, a "hook" in the fitted ROC may be evident near the upper-right or lower-left corner of the unit square. To overcome this curve-fitting artifact, we developed a "proper" binormal model and a new algorithm for maximum-likelihood (ML) estimation of the corresponding ROC curves. Extensive simulation studies have shown the algorithm to be highly reliable. ML estimates of the proper and conventional binormal ROC curves are virtually identical when the conventional binormal ROC shows no "hook," but the proper binormal curves have monotonic slope for all data sets, including those for which the conventional model produces degenerate fits.

Comment on "Memory storage and retrieval processes in category learning"

This article is based on the Estes (1986b) article that examined learning processes associated with categorization in relation to new-old recognition. The focus of the commentary is on alternative views of recognition/classification relations as well as the implications of the more detailed analyses of learning for exemplar-based classification models. The argument is made that strategies typically used by experimental participants and exemplar processing have some fundamental properties in common. This implies that a good fit to classification data by an exemplar model does not necessarily mean that performance is based on comparisons with remembered exemplars but suggests that abstract representations may not be different kinds of entities from the memory representation of a specific experience.     

Effects of signaling inescapable shock on subsequent escape learning: implications for theories of coping and "learned helplessness"

The present experiments reveal that shuttle-escape performance deficits are eliminated when exteroceptive cues are paired with inescapable shock. Experiment 1 indicated that, as in instrumental control, a signal following inescapable shock eliminated later escape performance deficits. Subsequent experiments revealed that both forward and backward pairings between signals and inescapable shock attenuated performance deficits. However, the data also suggest that the impact of these temporal relations may be modulated by qualitative aspects of the cues because the effects of these relations depended upon whether an increase or decrease in illumination (Experiment 2) or a compound auditory cue (Experiment 4) was used. Preliminary evidence suggests that the ability of illumination cues to block escape learning deficits may be related to their to reduce contextual fear (Experiment 3). The implications of these data for conceptions of instrumental control and the role of fear in the etiology of effects of inescapable shock exposure are discussed.     

"Nonlabeled" family interaction: prelimiary report on a prospective study.

This paper is a preliminary report on the first year of a two-year exploratory, prospective study of psychiatrically "nonlabeled" families. The project studies families from a nonpathology-oriented point of view. It focuses primarily on whole-family interaction as it progresses through time. Because of limited funds, only two families are being studied in this exploratory phase. Nevertheless, the work touches on many issues of a general nature that may be of interest of other researchers. Each family has been interviewed once a month for the past year. The paper outlines: procedural matters, including selection criteria and recruitment; data collection, including interviews, rating scales, and "clinical" discussions; processing of data; preliminary findings, including quantitative and qualitative aspects; and problem areas, including methodological and ethical aspects.     

The "consciousness problem" is not the problem.

Although the concept of consciousness is not necessary for the behavioral scientist, it is closely related to a number of psychological concepts that are generally believed to be necessary. Consciousness may be defined as the very short-term memory of a just-completed perceptual act. It may thus be understood as a psychological consequence of psychological antecedents. The question of how brain processes result in consciousness is a misleading one and should be replaced by questions concerning the relationships between the brain and perception, memory, and the other psychological processes that precede consciousness.     

"Official" Doctrine and "Unofficial" Practices: The Negotiation of Catholicism in a Netherlands Community

This article examines the Dutch Catholic Church. It is based on a qualitative ethnographic analysis of a particular Dutch Catholic community. It seeks to demonstrate that despite a decline in the church since the 1960s many Dutch parishioners are becoming active in redefining the church and attempting to revitalize Catholicism, creating democratically organized local communities where laity and local clergy, women and men, work together as equals in negotiating change, but argues that this may involve "unofficial" practices, possibly at odds with "official" church hierarchy controlled doctrine, which may resist acknowledging them and resist change. By examining these issues, the article aims to understand the dialectic and tension between what could be termed "popular" and "orthodox", "private" and "public", beliefs and to examine the constraints or possibilities this may place on the church. In this sense, the article also aims to explore how religion, thought to be vulnerable to recent change encouraging individual independence from social institutions, may negotiate (or reject) new developments. Although challenged, Catholic identity may still be valued and provide individuals with resources for negotiating new developments. However, the success or failure of this may depend on the nature of the struggle for authority and influence between "official" and "unofficial" versions of Catholicism.     

Are critical items "critical" for the MMPI-A

This article examines one aspect of the potential usefulness of critical items to the: Minnesota Multiphasic Personality Inventory -Adolescent (MMPI-A). Endorsement frequency data are presented on the Koss-Butcher (1973) and the Lachar-Wrobeli (1979) critical items for Minnesota Multiphasic Personality Inventory-2 (MMPI-2) adult normative and clinical samples and for MMPI-A adolescent normative and clinical samples. Adolescents in both normal and clinical samples endorse critical items with a higher frequency than do normal adults. Further, results demonstrated that significant differences were uniformly found between the endorsement frequencies for normative versus clinical subjects for the MMPI-2 samples, whereas similar comparisons for the MMPI-A samples typically showed that adolescents in clinical setting did not endorse critical items more frequently than normal adolescents. These findings indicate that it may be difficult to construct critical item lists for adolescents based on the type of empirical methodology used with adults in which items are selected based on endorsement frequency differences found between comparison group. Beyond the issue of the technical difficulty in creating a critical item list for adolescents, several conceptual concerns are raised regarding the application of critical items to the MMPI-A. It was noted that the concept of "critical items" has not been we11 defined, and both the reliability and validity of critical items may be limited in adolescent populations.     

Read but not write "idea": evidence for a third reading mechanism

Most information processing accounts of reading incorporate either two or three mechanisms by which oral reading may be accomplished. The existence of a "third" mechanism by which words may be read lexically but without semantic mediation remains controversial. We report data from a patient (W.T.) with an infarction involving Wernicke's area who was unable to write, repeat, or comprehend words of low imageability yet read these and other words reliably; the patient could not, however, read nonwords. As the patient was unable to read on the basis of sublexical print-to-sound correspondences and, at least for words of low image-ability, was unable to read by means of a semantically mediated process, the data from this patient are most readily accommodated by models of reading incorporating three mechanisms.     

"Replacing" problem behavior: an analysis of tactical alternatives

A number of textbooks and professional volumes in applied behavior analysis suggest that interventions designed primarily to decrease a problem behavior should routinely be accompanied by efforts to increase the frequency of at least one appropriate behavior. Some sources describe the objective of this tactic as "replacing" the problem behavior. This paper considers rationales that might underlie this advice, as well as reasons why a general rule to this effect is inappropriate. This review reveals that although there may well be good reasons for considering this tactic, their rationales are often not well articulated and may even be unsound. It is also the case that there are good reasons why this tactic may not always be necessary, thus conflicting with an argument for a general rule.     

"SOME THINGS YOU LEARN AREN'T SO":

When interpreting an interaction in the analysis of variance (ANOVA), many active researchers (and, in turn, students) often Ignore the residuals defining the interaction Although this problem has been noted previously, a appears that many users of ANOVA remain uncertain about the proper understanding of interaction effects To clear up this problem, we review the way in which the ANOVA model enables us to take apart a table of group means or the individual measurements contributing to the means to reveal the underlying components We also show how (using only published data) to compute a contrast on the question that may be of primary interest and illustrate for interpreting tables of residuals We conclude with an exercise to check on students understanding of ANOVA and to encourage increased precision in the specification of research results     

Women's Perceptions of the Prison Environment: When Prison is "the safest place i've ever been"

Incarcerated women's perceptions of the prison environment were explored with respect to relative level of safety from interpersonal abuse in prison as compared to before incarceration. Perceived levels of safety were analyzed based on reported past experiences of interpersonal violence. Participants were 65 women incarcerated in a medium security prison for women with mental and physical health problems. Women's perceptions of safety were evaluated using close–ended quantitative and open–ended qualitative self–report questions. The results suggest that, for some women, prison may be a relatively safe environment and that perceived level of safety may vary with the extent of previous experience of interpersonal violence in childhood and adulthood. Given that the structure of correctional institutions often incorporates abusive dynamics, the directionality of the findings is theoretically and socially important. The patterns apparent in these data are also consistent with other research and theory on the experiences of incarcerated women.     

"They" as a gender-unspecified singular pronoun: eye tracking reveals a processing cost

The plural pronouns they and them are used to refer to individuals with unknown gender and when a random allocation of gender is undesirable. Despite this apparently felicitous usage, “singular they/them” should raise processing problems under the theory that pronouns seek gender- and number-matched antecedents. Using eye-tracking, we investigated whether there was any processing cost associated with using singular they/them. There was a clear cost of number incompatibility for they/them. Thus, although singular they/them is in current usage, it does not appear that they/them is immediately tolerant of a plural antecedent, though such may be rapidly accommodated. The data are consistent with the search account of pronoun resolution and preserve the semantics of they/them as denoting plurality.     

Origins of "us" versus "them": prelinguistic infants prefer similar others

A central feature of human psychology is our pervasive tendency to divide the social world into "us" and "them". We prefer to associate with those who are similar to us over those who are different, preferentially allocate resources to similar others, and hold more positive beliefs about similar others. Here we investigate the developmental origins of these biases, asking if preference for similar others occurs prior to language and extensive exposure to cultural norms. We demonstrate that, like adults, prelinguistic infants prefer those who share even trivial similarities with themselves, and these preferences appear to reflect a cognitive comparison process ("like me"/"not like me"). However, unlike adults, infants do not appear to prefer others with an utterly arbitrary similarity to themselves. Together, these findings suggest that the phenomena of ingroup bias, and enhanced interpersonal attraction toward those who resemble ourselves, may be rooted in an inherent preference for similarity to self, which itself may be enhanced during development by the influence of cultural values.     

What catatonia can tell us about "top-down modulation": a neuropsychiatric hypothesis

Differential diagnosis of motor symptoms, for example, akinesia, may be difficult in clinical neuropsychiatry. Symptoms may be either of neurologic origin, for example, Parkinson's disease, or of psychiatric origin, for example, catatonia, leading to a so-called "conflict of paradigms." Despite their different origins, symptoms may appear more or less clinically similar. Possibility of dissociation between origin and clinical appearance may reflect functional brain organisation in general, and cortical-cortical/subcortical relations in particular. It is therefore hypothesized that similarities and differences between Parkinson's disease and catatonia may be accounted for by distinct kinds of modulation between cortico-cortical and cortico-subcortical relations. Catatonia can be characterized by concurrent motor, emotional, and behavioural symptoms. The different symptoms may be accounted for by dysfunction in orbitofrontal-prefrontal/parietal cortical connectivity reflecting "horizontal modulation" of cortico-cortical relation. Furthermore, alteration in "top-down modulation" reflecting "vertical modulation" of caudate and other basal ganglia by GABA-ergic mediated orbitofrontal cortical deficits may account for motor symptoms in catatonia. Parkinson's disease, in contrast, can be characterized by predominant motor symptoms. Motor symptoms may be accounted for by altered "bottom-up modulation" between dopaminergic mediated deficits in striatum and premotor/motor cortex. Clinical similarities between Parkinson's disease and catatonia with respect to akinesia may be related with involvement of the basal ganglia in both disorders. Clinical differences with respect to emotional and behavioural symptoms may be related with involvement of different cortical areas, that is, orbitofrontal/parietal and premotor/motor cortex implying distinct kinds of modulation--"vertical" and "horizontal" modulation, respectively.     

"LIKE CHEWING GRAVEL"

The researcher's role in creating knowledge and interpretations is of critical concern as new research methods are developed. Recent attention has been given to the "implications of difference" on the research process; however, the processes of analysis/interpretation and presentation of research remain to be illuminated. Seeking to address this, I present my experiences as a White researcher of middle socioeconomic status (SES) conducting qualitative research about childbearing with several pregnant Black American adolescents of lower SES. Although the research process was consistent with qualitative research methods, initial analyses of the data led to findings that seemed far afield from the participants' worlds. I subsequently reanalyzed the data with the principles of a feminist epistemology (Harding, 1991) in mind. The impact of using this epistemology on the processes of analysis and interpretation and my presentation of the data are presented. The results support the importance of developing feminist methodology and epistemology and provide new direction for further work.     

Freud's "Project": a theory for Studies on Hysteria

The controversy about the place of Sigmund Freud's unfinished draft of 1895, "Project for a Scientific Psychology," in the history of his thought, is addressed. It is argued that the "Project" may be understood as a suppressed response to the theory of hysteria presented by Josef Breuer in his and Freud's joint work, Studies on Hysteria. It is suggested that the "Project" may be read, in part, as a substitute for Breuer's theory. The timing and circumstances of the "Project's" composition are discussed. Its substantive and formal congruence with Studies on Hysteria is brought out. Freud's comments on scientific hypotheses are discussed, and it is shown that they constitute an implicit criticism of Breuer's theory.     

Comments on Smedslund's "Revising explications of common sense through dialogue"

Smedslund's attempt to show that common sense is invariant is discussed. It is pointed out that he used a new definition of common sense as well as instructions which maximize invariance. Therefore, the findings demonstrate merely that the subjects utilized well known folk psychological concepts in their inferences. They cannot be generalized to other, real-life, situations and to the usual meaning of the term common sense. The use of dialogue to increase invariance may work in an artificial setting where little is at stake but may well increase and freeze differences of opinion in real-life settings. Still, Smedslund should be given credit for initiating work at a conceptual level which is badly needed, as illustrated here with an example from work on intrinsic motivation.     

"Working through" and the novel

Prone to jargon, psychoanalytic literary criticism must be circumspect lest it appear narrow, sectarian, judgmental or exploit a particular psychoanalytic theory. Salient imagery, symbolism, metaphor, and psychologically intuitive characterization in the novel may be viewed as evocative of central, conflictual, predominantly unconscious source of experience or fantasy (Arlow, 1979) synchronizing with autobiographical and biographical data in achieving more dynamic, interpretive syntheses. VW's emotional state is an emergent of her total personality interacting with and evolving in her highly complex family milieu. Though she claimed writing the novel modulated the preoccupation with her parents, essentially VW did not resolve her obsession with the cumulative and untimely deaths of her parents and siblings but engaged in her writing in a perpetual mourning of these and other psychological losses for most of her life. Her life and work reflect the processes of "repetition" and "elaboration" also intrinsic to the psychoanalytic process but she did not achieve the memory "reconstructions" and "changes in self-esteem" alluded to by Kris (1956a, 1956b) and Greenson (1965) as intrinsic to the psychoanalytic experience of insight and "working through."
