A general response style factor: Evidence from a multi-ethnic study in the Netherlands

In a cross-cultural study we addressed commonalities and differences of acquiescence, extremity, midpoint responding, and socially desirable responding that can be taken to constitute a single underlying response style. Participants were 548 Dutch nationals and 1116 first- and second-generation immigrants of Western and Non-Western origins in the Netherlands. Self-report measures of the four response styles, and personality traits were administered. Conventional, indirect measures of acquiescence, extremity, and midpoint responding were also calculated. A multigroup confirmatory factor analysis showed support for a general response style factor with positive loadings of extremity and socially desirable responding, and negative loadings of acquiescence and midpoint responding. The response style factor was strongly associated with personality (notably the “Big One” factor). Furthermore, acquiescence and impression management were related to agreeableness, extremity and midpoint responding to extraversion, and self-deceptive enhancement to neuroticism. These findings support a view that there is a general response style factor and that, in addition, each response style has some unique meaning. The ethnic groups differed significantly on response style use, with Non-Western immigrants showing higher acquiescence and midpoint responding than the other groups. The general response style factor can be interpreted as a communication filter that moderates self-reports. Implications are discussed.     

A theory of belief

A theory of belief is presented in which uncertainty has two dimensions. The two dimensions have a variety of interpretations. The article focusses on two of these interpretations.The first is that one dimension corresponds to probability and the other to “definiteness,” which itself has a variety of interpretations. One interpretation of definiteness is as the ordinal inverse of an aspect of uncertainty called “ambiguity” that is often considered important in the decision theory literature. (Greater ambiguity produces less definiteness and vice versa.) Another interpretation of definiteness is as a factor that measures the distortion of an individual's probability judgments that is due to specific factors involved in the cognitive processing leading to judgments. This interpretation is used to provide a new foundation for support theories of probability judgments and a new formulation of the “Unpacking Principle” of Tversky and Koehler.The second interpretation of the two dimensions of uncertainty is that one dimension of an event A corresponds to a function that measures the probabilistic strength of A as the focal event in conditional events of the form A|B, and the other dimension corresponds to a function that measures the probabilistic strength of A as the context or conditioning event in conditional events of the form C|A. The second interpretation is used to provide an account of experimental results in which for disjoint events A and B, the judge probabilities of A|(A∪B) and B|(A∪B) do not sum to 1.The theory of belief is axiomatized qualitatively in terms of a primitive binary relation ? on conditional events. (A|B?C|D is interpreted as “the degree of belief of A|B is greater than the degree of belief of C|D.”) It is shown that the axiomatization is a generalization of conditional probability in which a principle of conditional probability that has been repeatedly criticized on normative grounds may fail.Representation and uniqueness theorems for the axiomatization demonstrate that the resulting generalization is comparable in mathematical richness to finitely additive probability theory.     

Effects of a coactor's prediction on latencies to predict and indentify stimuli

On each of 300 trials E's confederate (C) verbalized which of two stimuli would occur; then S made a prediction. Following each presentation, S and C pulled a trigger to identify the stimulus. Two latencies were measured: the interval between C's and S's prediction (prediction time), and the interval between stimulus presentation and S's identification response (choice RT). Prediction times were significantly shorter when S's prediction agreed rather than disagreed with C's prediction, when S's preceding prediction was correct rather than incorrect, and when S was female rather than male. Choice RT was influenced by distributions of C's stimulus predictions and C's prediction outcomes in directions supporting an expectancy model.     

Effects of ownership expressed by the first-person possessive pronoun

The present study examined the behavioral effects of the first-person possessive pronoun. In each trial, a noun (e.g. cup or bread) was presented to participants after visual presentation of a possessive pronoun “wo de” (Chinese for “my”) or “ta de” (Chinese for “his”), which formed ownership. Half participants were assigned to contextual encoding (CE) condition in which they were required to judge whether they liked the item expressed by a noun from the first or third-person perspective. The rest were assigned to perceptual encoding (PE) condition in which they were asked to judge what color the noun was. A subsequent recall test was performed. The results showed that there were significant memory and response advantages for nouns in “my” ownership under both conditions. The results were discussed with reference to self-specificity and other effects in the current study.     

Usage-based account of the acquisition of liaison: evidence from sensitivity to the singular/plural orientation of nouns

This study investigates whether children’s production and recognition of obligatory liaison sequences in French depend on the singular/plural orientation of nouns. Certain nouns occur more frequently in the plural (e.g., arbre “tree”), whereas others are found more often in the singular (e.g., arc-en-ciel “rainbow”). In the input, children more frequently encounter these plural-oriented nouns after determiners that indicate plurality (e.g., les,des “the”, deux “two”) and that are often associated with a /z/ liaison (e.g., deux arbres [døzarbr] “two trees”). In Experiment 1, 122 children (3 years 2 months to 6 years 3 months of age) were asked to produce nominal phrases with either /z/ liaisons (i.e., in plural contexts such as deux ours [døzurs] “two bears”) or /n/ liaisons (i.e., in singular contexts such as un ours [nurs] “one bear”). We found correlations between the plural orientation of the nouns and (a) the probability that they will be preceded by an incorrect /z/ liaison in the singular context and (b) the probability that they will be preceded by a correct /z/ liaison in the plural context. This result was, however, restricted to the younger children. In Experiment 2, 20 children (5 years 5 months to 6 years 3 months of age) were asked to monitor target words in auditorily presented sentences. The results showed shorter reaction times for singular-oriented nouns when preceded by a singular determiner than when preceded by a plural determiner. Conversely, plural-oriented nouns were responded to faster when preceded by a plural determiner than when preceded by a singular determiner. Results are discussed within the framework of a two-stage model of liaison acquisition recently proposed by Chevrot, Chabanal, and Dugua (Journal of French Language Studies,17 [2007] 103-128) as well as by Chevrot, Dugua, and Fayol (Journal of Child Language [in press]).     

The embodied cognition theory and the motor component of “yes” and “no” verbal responses

Most of the experiments which give theories of embodied cognition their empirical anchorage only take into consideration the motor responses induced by the task or the motor component of the visual stimulus. And yet, these motor responses are often associated with a linguistic answer. Our hypothesis is that “YES” and “NO” verbal responses have a motor component. In a first experiment we showed that producing a verbal response (YES vs. NO) involves motor planning (pushing vs. pulling): participants push a lever more quickly when they have to answer “yes” than “no”, and conversely, they pull a lever more quickly when they have to answer “no” than “yes”. Moreover, in a second experiment, we showed that perceiving the words “YES” and “NO”, on its own, leads to the same motor planning than when “yes” and “no” answers actually have to be produced. Participants detect the word “YES” faster when they have to push a lever than when they have to pull it and conversely they detect the word “NO” faster when they have to pull the lever than when they have to push it down. These results are discussed in reference to “online” and “offline embodiment” concepts and to the cognitive linguistic theories.     

Temporal order perception of auditory stimuli is selectively modified by tonal and non-tonal language environments

The close relationship between temporal perception and speech processing is well established. The present study focused on the specific question whether the speech environment could influence temporal order perception in subjects whose language backgrounds are distinctively different, i.e., Chinese (tonal language) vs. Polish (non-tonal language). Temporal order thresholds were measured for both monaurally presented clicks and binaurally presented tone pairs. Whereas the click experiment showed similar order thresholds for the two language groups, the experiment with tone pairs resulted in different observations: while Chinese demonstrated better performance in discriminating the temporal order of two “close frequency” tone pairs (600 Hz and 1200 Hz), Polish subjects showed a reversed pattern, i.e., better performance for “distant frequency” tone pairs (400 Hz and 3000 Hz). These results indicate on the one hand a common temporal mechanism for perceiving the order of two monaurally presented stimuli, and on the other hand neuronal plasticity for perceiving the order of frequency-related auditory stimuli. We conclude that the auditory brain is modified with respect to temporal processing by long-term exposure to a tonal or a non-tonal language. As a consequence of such an exposure different cognitive modes of operation (analytic vs. holistic) are selected: the analytic mode is adopted for “distant frequency” tone pairs in Chinese and for “close frequency” tone pairs in Polish subjects, whereas the holistic mode is selected for “close frequency” tone pairs in Chinese and for “distant frequency” tone pairs in Polish subjects, reflecting a double dissociation of function.     

Optimism and pessimism dimensions in the Life Orientation Test-Revised: Method and meaning

The Life Orientation Test and its revision include items tapping both the belief that good things will happen (optimism) and the belief that bad things will not happen (low pessimism). The present investigation addressed the relationship of optimism and pessimism from psychometric and substantive perspectives. Two variations of the LOT-R, one with standard items and one with extreme adverbs (e.g., “always”) removed, were administered to undergraduate (n = 971) and web-based samples (n = 2806). Although there was psychometric support for a bidimensional structure in both versions, only the revised version showed substantive differences in the correlations of optimism versus pessimism with personality criteria. The generic recommendation is to use the original, unidimensional scale.     

Objects, events and "to be" verbs in Spanish--an ERP study of the syntax-semantics interface

In Spanish, objects and events at subject position constrain the selection of different forms of the auxiliary verb “to be”: locative predicates about objects require “estar en”, while those relating to events require “ser en”, both translatable as “to be in”. Subjective ratings showed that while the “object + ser + en” is considered as incorrect, the “event + estar + en” combination is also perceived as unacceptable but to a lesser degree. In an ERP study, we evaluated the impact of a purely semantic distinction (object versus events) on the subsequent processing of these auxiliary verbs followed by locatives in Spanish. For the “ser en” predicate, the P600 component was larger when the subject was an object than when it was an event. This P600 effect is consistent with an online repair of the defining predicate when it does not fit with the adequate semantic properties of the subject. On the other hand, for the “estar en” predicate, event subjects when compared to object subjects showed more positive ongoing amplitudes between 280 and 380 ms after the presentation of the “en” preposition, followed by a longer positive wave starting around 400 ms and lasting until 700 ms after the presentation of the following determiner, with central and frontal scalp distributions respectively. Thus, the different subject-predicate combinations, depending on the semantic features of the subjects, triggered syntactic reparatory processes at a structural level. These findings are consistent with an incremental interpretation of sentence meaning based on the interaction between syntactic and semantic information.     

Perception of acoustically presented time series with varied intervals

Data from three experiments on serial perception of temporal intervals in the supra-second domain are reported. Sequences of short acoustic signals (“pips”) separated by periods of silence were presented to the observers. Two types of time series, geometric or alternating, were used, where the modulus 1 + δ of the inter-pip series and the base duration T_b (range from 1.1 to 6 s) were varied as independent parameters. The observers had to judge whether the series were accelerating, decelerating, or uniform (3 paradigm), or to distinguish regular from irregular sequences (2 paradigm). “Intervals of subjective uniformity” (isus) were obtained by fitting Gaussian psychometric functions to individual subjects' responses. Progression towards longer base durations (T_b = 4.4 or 6 s) shifts the isus towards negative δs, i.e., accelerating series. This finding is compatible with the phenomenon of “subjective shortening” of past temporal intervals, which is naturally accounted for by the lossy integration model of internal time representation. The opposite effect observed for short durations (T_b = 1.1 or 1.5 s) remains unexplained by the lossy integration model, and presents a challenge for further research.     

Étude exploratoire de la stabilité à long terme des indices standard du WISC-IV

By a Test–Retest procedure, this study explores the long-term stability of the French WISC-IV index scores. The average Test–Retest interval was 2.33 years. The sample consisted of 96 non-clinical children aged between 8 and 12 years. Mean difference between the two testings was not statistically significant for VCI, PRI, WMI, GAI and FSIQ. Test–Retest reliability correlations between the two assessments are high for VCI, GAI and FSIQ (ranging from .81 to .82). An analysis of the performance differences between two assessments indicates intra-individual stability for WMI and GAI. In sum, only GAI demonstrates reliable long-term stability at an inter-and intra-individual level.     

A generalization of Piéron's law to include background intensity and latency distribution

Piéron's law, which formulates the effect of the signal intensity i on the mean or the median reaction time (MRT) as a power function, MRT=R+i^-βC, in which R, β and C are positive parameters, is of much interest in the simple reaction time literature. In particular, consistent estimates of β are obtained. However, this law offers no information regarding the effect of the signal intensity on other aspects of the reaction time distribution. In addition, the background intensity, which also has some impact on the detectability of the signal, is not considered in Piéron's law. In this paper, we generalize Piéron's law based on the above comments. That is, we assume that both β and C are functions of the background intensity and of the percentile rank. We then investigate from a theoretical viewpoint some possible functional forms of β and C, with a special emphasis on the dependency of β on the background intensity. It is shown that the so-called “Fechner-Thurstone-type representation” forces β and C to be “separable.” If we further assume a near-miss to Weber's law-type representation, then the functional form of β can be determined.     

A longitudinal study of the vocationally undecided male student

Graduating seniors (n = 137) who were vocationally undecided as freshmen were compared to seniors who had persisted in a major or had immigrated to each of the six Holland vocational categories. No differences were found on personality as measured by the Omnibus Personality Inventory or ability as measured by the American College Test. The assumption that the “immigrant” sample might conceal differences between changers from one Holland category to another and originally undecided students was not supported.     

Losing sight of oneself in the above-average effect: When egocentrism, focalism, and group diffuseness collide

Four experiments examined the relative influence of three causal processes in the above-average effect (AAE) and related comparative biases: (a) egocentrism, (b) focalism, and (c) referent group diffuseness. By manipulating the inclusion or exclusion of the self from the referent group (Experiments 1-3) or target group (Experiment 4), the relative contributions of each influence were assessed. In direct comparisons, single peers were systematically judged more favorably relative to groups including the self, suggesting that egocentrism plays a lesser role than focalism or group diffuseness. Thus, in response to the question such as “How friendly is Nancy compared to the rest of us?” the answer tends to be “More friendly.”     

Focussing on overexcitabilities: Studies with intellectually gifted and academically talented adults

The concept of “overexcitability” has recently become popular within the field of giftedness and talent research. Some authors argue that overexcitability questionnaires can be used to identify gifted/talented individuals. A sample of intellectually gifted adults (n = 96; mean age: 31.4; SD = 0.3) was compared to a sample of adults of average intelligence (n = 91; mean age: 31.4; SD = 0.4). Additionally, a sample of 123 high achievers (mean age = 30.5; SD = 0.3) was compared to 97 average achievers (mean age: 30.5; SD = 0.3). The “Overexcitability Questionnaire-Two” was used to assess emotional, imaginational, intellectual, psychomotor, and sensual overexcitability. The gifted adults scored statistically significantly higher on “intellectual overexcitability” (d = .42). High and average achievers differed statistically significantly in “intellectual overexcitability” (d = .56) and “sensual overexcitability” (d = .32). For the giftedness sample, the accuracy of group membership prediction (gifted/non-gifted) via discriminant analyses was 60.4%. For the performance sample, the accuracy was 63.4%. The observed differences in the overexcitabilities were small; the risk of misclassification is too big to attempt to identify gifted or high achieving adults solely on the basis of overexcitability scores.     

A counterexample to Fishburn's conjecture on finite linear qualitative probability

Kraft, Pratt and Seidenberg (Ann. Math. Statist. 30 (1959) 408) provided an infinite set of axioms which, when taken together with de Finetti's axiom, gives a necessary and sufficient set of “cancellation” conditions for representability of an ordering relation on subsets of a set by an order-preserving probability measure. Fishburn (1996) defined f(n) to be the smallest positive integer k such that every comparative probability ordering on an n-element set which satisfies the cancellation conditions C₄,…,C_k is representable. By the work of Kraft, Pratt, and Seidenberg (1959) and Fishburn (J. Math. Psychol. 40 (1996) 64; J. Combin. Design 5 (1997) 353), it is known that n-1?f(n)?n+1 for all n?5. Also Fishburn proved that f(5)=4, and conjectured that f(n)=n-1 for all n?5. In this paper we confirm that f(6)=5, but give counter-examples to Fishburn's conjecture for n=7, showing that f(7)?7. We summarise, correct and extend many of the known results on this topic, including the notion of “almost representability”, and offer an amended version of Fishburn's conjecture.     

Subtyping eating disordered patients along drive for thinness and depression

Subtyping individuals who binge eat by “diet-DT” and “depression” has yielded two valid and clinically useful subtypes that predict eating severity, comorbid psychopathology and outcome. The present study aimed to find four subtypes based on these dimensions and test their validity. Besides, it explored the distribution of eating disorder (ED) diagnoses across subtypes given their known heterogeneity, crossover and binge-eating fluctuation.Cluster analysis grouped 1005 consecutively admitted ED adult women into four subtypes, those previously described “DT” (22%), “DT-depressive” (29%), and “mild DT” (25%) and “depressive-moderate DT” (24%). Overall “mild DT” presented lower and “DT-depressive” greater eating and comorbid psychopathology than the rest, whereas “pure DT” and “depressive-moderate DT” presented no differences on bulimic symptoms but in psychopathology (p < .01). Finally, while BN-P patients were mostly and similarly distributed in the “DT” and “DT-depressive” subtypes than in the other, AN were in the new “mild DT” and “depressive-moderate DT” (p < .01). However, BN-NP, BED and EDNOS were similarly represented across subtypes.Results are discussed with regard to 1) the newly emerged subtypes that may explain cases in which DT prevents or does not predict binge eating; 2) the confluence of DT-depression that signaled greater eating and comorbid pathology, particularly self-control problems; 3) ED-DSM-diagnostic criteria.     

Mere acceptance produces apparent attitude in the Implicit Association Test

Two experiments examined mere acceptance effects in the Implicit Association Test (IAT). They tested whether accepting a stimulus as conforming to a rule produces responding consistent with positive attitude in the IAT. In Experiment 1, accepted stimuli were more easily categorized with pleasant personality characteristics than rejected stimuli; they were preferred according to the logic of the IAT. Accepted word stimuli were also responded to faster overall, suggesting that it was easier to make the accept than the reject response. In Experiment 2, numerical stimuli that conformed to a rule showed the same IAT preference effect over non-confirming stimuli, even when the rule conforming stimuli were more difficult to categorize. Three sources of this apparent preference for rule-conforming stimuli are considered: (1) the semantic relatedness of the concepts “accept” and “pleasant” on the one hand, and “reject” and “unpleasant” on the other; (2) that rejected non-category members are more salient (‘pop-out’) and thus are more easily categorized with the more salient unpleasant personality characteristics; or (3) that accepting rule-conforming stimuli is experienced as a pleasant event. Regardless of the mechanism underlying the mere acceptance effect, the IAT can produce apparent preferences for stimuli towards which participants have no positive attitude.     

Sick? Or slow? On the origins of intelligence as a psychological object

This paper examines the first moments of the emergence of “psychometrics” as a discipline, using a history of the Binet–Simon test (precursor to the Stanford–Binet) to engage the question of how intelligence became a “psychological object.” To begin to answer this, we used a previously-unexamined set of French texts to highlight the negotiations and collaborations that led Alfred Binet (1857–1911) to identify “mental testing” as a research area worth pursuing. This included a long-standing rivalry with Désiré-Magloire Bourneville (1840–1909), who argued for decades that psychiatrists ought to be the professional arbiters of which children would be removed from the standard curriculum and referred to special education classes in asylums. In contrast, Binet sought to keep children in schools and conceived of a way for psychologists to do this. Supported by the Société libre de l'étude psychologique de l'enfant [Free society for the psychological study of the child], and by a number of collaborators and friends, he thus undertook to create a “metric” scale of intelligence—and the associated testing apparatus—to legitimize the role of psychologists in a to-that-point psychiatric domain: identifying and treating “the abnormal”. The result was a change in the earlier law requiring all healthy French children to attend school, between the ages of 6 and 13, to recognize instead that otherwise normal children sometimes need special help: they are “slow” (arriéré), but not “sick.” This conceptualization of intelligence was then carried forward, through the test's influence on Lewis Terman (1877–1956) and Lightner Witmer (1867–1956), to shape virtually all subsequent thinking about intelligence testing and its role in society.     

Using morphology when spelling in a shallow orthographic system: The case of Spanish

Deep orthographies usually represent morphology and phonology simultaneously; both resources are necessary for spelling. In shallow orthographies, such as Spanish, phonology would be enough to spell most words. However, morphological knowledge may also take part in spelling. This study examined how Spanish children in 1st (N = 148), 2nd (N = 155) and 3rd grade (N = 155) use morphological information to spell plural nouns and verbs. A word dictation task was designed. The task included high and low frequency plural nouns ending in “s” (morphological “-s” condition) and verbs in the 2nd person ending in “s” (morphological “-s” condition). A lexical condition including words with a final “s” which was not morphologically motivated was used as a control condition (lexical “-s” condition). The results show that, although Spanish spelling is influenced by phonology, morphological information is also used. These results are discussed in relation to current models of word spelling.
