Multiple Evaluation: A New Testing Paradigm That Exorcizes Guessing

The crux in psychometrics is how to estimate the probability that a respondent answers an item correctly on one occasion out of many. Under the current testing paradigm this probability is estimated using all kinds of statistical techniques and mathematical modeling. Multiple evaluation is a new testing paradigm using the person's own personal estimates of these probabilities as data. It is compared to multiple choice, which appears to be a degenerated form of multiple evaluation. Multiple evaluation has much less measurement error than multiple choice, and this measurement error is not in favor of the examinee. When the test is used for selection purposes as it is with multiple choice, the probability of a Type II error (unjustified passes) is almost negligible. Procedures for statistical item-and-test analyses under the multiple evaluation paradigm are presented. These procedures provide more accurate information in comparison to what is possible under the multiple choice paradigm. A computer program that implements multiple evaluation is also discussed.     

An exploratory study of psychodynamic therapists’ working with people with multiple sclerosis

There is little published on working psychodynamically with chronic illness and even less on the clinical insights of therapists working with people with multiple sclerosis. The objective of this study was to consider therapists’ reflections on the impact of multiple sclerosis on the internal worlds of clients with multiple sclerosis. I would also like to think about the challenges multiple sclerosis presents and how these challenges are worked with therapeutically. Finally, the impact of my multiple sclerosis diagnosis upon the research interviews was considered. Twelve counsellors / psychotherapists who had experience of working with clients with multiple sclerosis were interviewed. Data was analysed thematically and the findings revealed a number of significant themes. Denial appeared significant both for those with multiple sclerosis and those therapists working with them. Therapists also identified that people with multiple sclerosis hold a range of conscious and unconscious feelings in relation to their multiple sclerosis. Also, the meanings and impact of multiple sclerosis are broad and idiosyncratic. Therapists also faced a number of challenges in their work with people with multiple sclerosis: powerful countertransference feelings which could disable the therapy, embodied countertransference, the tendency to make generalisations, the physical reality of multiple sclerosis and its impact upon continuity, therapists’ unconscious phantasy and associations which if unaddressed could impact their ability to work with illness and the pressure multiple sclerosis placed on therapeutic boundaries. Therapists within the study recognised the need to work with both the physical reality of multiple sclerosis, as well as its psychological impact while at the same time keeping themselves open to powerful countertransference feelings and using them in the service of the therapy. The study has implications for theory, practice and future research.     

Studying visual attention using the multiple object tracking paradigm: A tutorial review

Human observers are capable of tracking multiple objects among identical distractors based only on their spatiotemporal information. Since the first report of this ability in the seminal work of Pylyshyn and Storm (1988, Spatial Vision, 3, 179–197), multiple object tracking has attracted many researchers. A reason for this is that it is commonly argued that the attentional processes studied with the multiple object paradigm apparently match the attentional processing during real-world tasks such as driving or team sports. We argue that multiple object tracking provides a good mean to study the broader topic of continuous and dynamic visual attention. Indeed, several (partially contradicting) theories of attentive tracking have been proposed within the almost 30 years since its first report, and a large body of research has been conducted to test these theories. With regard to the richness and diversity of this literature, the aim of this tutorial review is to provide researchers who are new in the field of multiple object tracking with an overview over the multiple object tracking paradigm, its basic manipulations, as well as links to other paradigms investigating visual attention and working memory. Further, we aim at reviewing current theories of tracking as well as their empirical evidence. Finally, we review the state of the art in the most prominent research fields of multiple object tracking and how this research has helped to understand visual attention in dynamic settings.     

Interactions between constituent single symmetries in multiple symmetry

As a rule, the discriminability of multiple symmetries from random patterns increases with the number of symmetry axes, but this number does not seem to be the only determinant. In particular, multiple symmetries with orthogonal axes seem better discriminable than multiple symmetries with nonorthogonal axes. In six experiments on imperfect two-fold symmetry, we investigated whether this is due to extra structure in the form of so-called correlation rectangles, which arise only in the case of orthogonal axes, or to the relative orientation of the axes as such. The results suggest that correlation rectangles are not perceptually relevant and that the percept of a multiple symmetry results from an orientation-dependent interaction between the constituent single symmetries. The results can be accounted for by a model involving the analysis of symmetry at all orientations, smoothing (averaging over neighboring orientations), and extraction of peaks.     

Tests of behavior momentum in simple and multiple schedules with rats and pigeons.

Four experiments examined the relationship between rate of reinforcement and resistance to change in rats' and pigeons' responses under simple and multiple schedules of reinforcement. In Experiment 1, 28 rats responded under either simple fixed-ratio, variable-ratio, fixed-interval, or variable-interval schedules; in Experiment 2, 3 pigeons responded under simple fixed-ratio schedules. Under each schedule, rate of reinforcement varied across four successive conditions. In Experiment 3, 14 rats responded under either a multiple fixed-ratio schedule or a multiple fixed-interval schedule, each with two components that differed in rate of reinforcement. In Experiment 4, 7 pigeons responded under either a multiple fixed-ratio or a multiple fixed-interval schedule, each with three components that also differed in rate of reinforcement. Under each condition of each experiment, resistance to change was studied by measuring schedule-controlled performance under conditions with prefeeding, response-independent food during the schedule or during timeouts that separated components of the multiple schedules, and by measuring behavior under extinction. There were no consistent differences between rats and pigeons. There was no direct relationship between rates of reinforcement and resistance to change when rates of reinforcement varied across successive conditions in the simple schedules. By comparison, in the multiple schedules there was a direct relationship between rates of reinforcement and resistance to change during most tests of resistance to change. The major exception was delivering response-independent food during the schedule; this disrupted responding, but there was no direct relationship between rates of reinforcement and resistance to change in simple- or multiple-schedule contexts. The data suggest that rate of reinforcement determines resistance to change in multiple schedules, but that this relationship does not hold under simple schedules.     

Has the last decade of challenges to the multiple realization argument provided aid and comfort to psychoneural reductionists?

The previous decade has seen renewed critical interest in the multiple realization argument. These criticisms constitute a “second wave” of challenges to this central argument in late-20th century philosophy of mind. Unlike the first wave, which challenged the premise that multiple realization is inconsistent with reduction or type identity, this second wave challenges the truth of the multiple realization premise itself. Since psychoneural reductionism was prominent among the explicit targets of the multiple realization argument, one might think that this second wave of challenges provides important aid and comfort to reductionists. In this paper, however, I provide reasons for thinking it does not. This is not to the detriment of psychoneural reductionism because, as I also argue here, and unrecognized by the current non-reductive orthodoxy in philosophy of mind, one key argument among the first wave of criticisms of the multiple realization argument has never been adequately rejoined.     

Ethical Issues in the Use of Multiple Survey Reminders

This paper identifies and discusses ethical issues associated with the increasingly common use of multiple reminders in postal survey research. When undertaking postal surveys, it is common to improve response rates by contacting survey recipients multiple times encouraging them to complete the questionnaire. The ethical implications of the use of multiple reminders are rarely discussed in the literature advocating their use. The paper briefly reviews the arguments encouraging use of multiple reminders, and identifies and discusses the potential ethical issues raised by their use in postal surveys. A set of principles is then proposed for using multiple reminders in an ethically responsible way. It is argued that by following these principles, the use of multiple reminders should present no increased potential for harassment or coercion of survey recipients compared to alternative survey techniques. The use of these principles in a recent postal survey is then presented and discussed; a 60% response rate was achieved utilising multiple survey reminders in a way consistent with this set of principles.     

Addressing multiple relationships between clients and therapists in lesbian, gay, bisexual, transgender communities

Therapists working in lesbian, gay, bisexual, and transgender (LGBT) communities are likely to experience the potential to engage in multiple relationships with their clients. Currently, the American Psychological Association's (2002) ethics code and the related literature base offer minimal direct guidance to therapists practicing in LGBT communities. In this article, the authors review current literature regarding multiple relationships in psychotherapy, considering how this literature addresses issues specific to practitioners working within LGBT communities, present a case study highlighting the negotiation of a multiple relationship between a client and therapist who both identify as lesbian, and offer recommendations for practitioners working within LGBT communities.     

The Puzzle of Multiple Endings

Why is it that most fictions present one and only one ending, rather than multiple ones? Fictions presenting multiple endings are possible, because a few exist; but they are very rare, and this calls for an explanation. We argue that such an explanation is likely to shed light on our engagement with fictions, for fictions having one and only one ending seem to be ubiquitous. After dismissing the most obvious explanations for this phenomenon, we compare the scarcity of multiple endings in traditional kinds of fiction to their profusion in the case of interactive fictions. This contrast poses a challenge to accounts of our engagement with fictions in terms of games of make‐believe. We conclude that solving this puzzle is likely to improve our philosophical understanding of fictions.     

An appraisal of preference for multiple versus mixed schedules

Pigeons' choice responses on either of two keys occasionally produced entry into a terminal link associated with that key. During the terminal links, responses produced access to grain according to mixed- or multiple-interval schedules. The multiple schedules provided stimuli correlated with the interval of time preceding reinforcement whereas the mixed schedules did not. The two subjects reliably preferred the multiple schedules to the mixed schedules throughout a series of replications. Preference for the multiple schedule was much smaller than suggested by earlier work comparing multiple and mixed schedules that had much higher rates of entry into the terminal links. Preference for the multiple schedule was greatly increased in this study when the rate of entry into the terminal schedules was increased. As in previous studies, these high preferences may have been the result of a sharp increase in the number of reinforcements on the multiple (as opposed to the mixed) schedule. The reliable but smaller preferences for the multiple schedule found with lower rates of entry into the terminal links were unconfounded by differences in the number of reinforcements obtained in the two terminal links.     

Multi- and unisensory visual flash illusions

The role of stimulus structure in multisensory and unisensory interactions was examined. When a flash (17 ms) was accompanied by multiple tones (each 7 ms, SOA < or =100 ms) multiple flashes were reported, and this effect has been suggested to reflect the role of stimulus continuity in multisensory interactions. In experiments 1 and 2 we examined if stimulus continuity would affect concurrently presented stimuli. When a relatively longer flash (317 ms) was accompanied by multiple tones (each 7 ms), observers reported perceiving multiple flashes. In experiment 3 we tested whether a flash presented near fixation would induce an illusory flash further in the periphery. One flash (17 ms) presented 5 degrees below fixation was reported as multiple flashes if presented with two flashes (each 17 ms, SOA =100 ms) 2 degrees above fixation. The extent to which these data support a phenomenological continuity principle and whether this principle applies to unisensory perception is discussed.

Investigation of Multiple Imputation in Low-Quality Questionnaire Data

The performance of multiple imputation in questionnaire data has been studied in various simulation studies. However, in practice, questionnaire data are usually more complex than simulated data. For example, items may be counterindicative or may have unacceptably low factor loadings on every subscale, or completely missing subscales may complicate computations. In this article, it was studied how well multiple imputation recovered the results of several psychometrically important statistics in a data set with such properties. Analysis of this data set revealed that multiple imputation was able to recover the results of these analyses well. Also, a simulation study showed that multiple imputation produced small bias in these statistics for simulated data sets with the same properties.     

Multiple stimulus presentation yields larger deficits in children with developmental dyslexia: A study with reading and RAN-type tasks

In this study, we examined the effect of multiple versus single stimulus presentation in typically developing readers and children with developmental dyslexia. The tasks involved either reading single words or arrays of words or naming single or multiple colors and digits (rapid automatized naming or RAN). To be able to compare these sets of conditions, we recorded total response times (i.e., the time between stimulus onset and the end of the participant’s vocal response) in all cases. The study included 43 typically developing readers and 25 children with dyslexia.

Results indicate that typically developing readers have a clear advantage with multiple over single items on both RAN and reading tasks. The children with dyslexia showed a moderate advantage for multiple stimuli in naming colors and digits but presented the opposite pattern in reading.

With regard to reading, the disproportionate impairment of the children with dyslexia in dealing with multiple arrays suggests difficulty in integrating the multiple subcomponents of the reading task over and above the basic nuclear deficit in decoding words. Regarding the RAN tasks, results confirm that the requirement of integrating multiple subcomponents may be critical in mediating the predictive value of these measures on reading.     

“一”人代言的魅力：品牌代言人数如何影响消费者的品牌态度

有的品牌仅邀请一位名人代言, 而有的品牌由多位名人代言, 那么一人代言还是多人代言会更有效?为了回答该问题, 研究基于形象转移视角和单人积极偏差, 深入探究了品牌代言人数因素(一位代言人vs.多位代言人)对品牌态度的影响机制和边界条件。研究发现：相比品牌多人代言, 品牌单人代言使消费者的品牌态度更高。原因在于消费者与一位(vs.多位)品牌代言人的自我-品牌联结更紧密, 进而促进品牌态度。该品牌代言人效应仅局限于象征型产品, 而对于非身份象征型产品, 品牌单人代言(vs.品牌多人代言)对品牌态度无显著差异。此外, 当多位品牌代言人为一个团体时, 品牌代言人数效应将被逆转, 即品牌多人代言(vs.品牌单人代言)对品牌态度的影响更高。     

A Liberal Conception of Multiple Realizability

While the concept of multiple realizability is widely used, it is sedom rigorously characterized. This paper defends a liberal conception of multiple realizability as sameness of type through any differences in the (lower-level) conditions that give rise to instances of that type. This kind of “sameness through difference” is contrasted with another type of asymmetric dependency relation between properties, multiple specification. This liberal conception is then defended from objections, and it is augmented by a concept of relativized multiple realizability. The last section presents a survey of the ontological, explanatory, and methodological consequences of this analysis of multiple realizability.     

Epileptic seizures in multiple sclerosis

Starting from informations in the literature, the authors deals with eight own cases, suffering from clinically certain multiple sclerosis and showing, as a further sign, epileptic seizures. Compared to the total of patients, these eight cases represent 1.78 p.c. of all patients treated for multiple sclerosis in this clinic. The features of seizures, frequency and dynamics of occurrence are referred to. The authors point out that it is necessary to differential between epileptic seizures and non-epileptic attacks, and they draw attention to the fact that here are difficulties with regard to differential diagnosis if epileptic seizure appears as a initial symptom of multiple sclerosis.
