A closer look at moral dilemmas: Latent dimensions of morality and the difference between trolley and footbridge dilemmas

Although a distinction between moral-personal and moral-impersonal dilemmas (Greene, Sommerville, Nystrom, Darley, & Cohen, 2001 Greene, J. D., Sommerville, R. B., Nystrom, L. E., Darley, J. M. and Cohen, J. D. 2001. An fMRI investigation of emotional engagement in moral judgement. Science, 293: 2105–2108. doi:10.1126/science.1062872.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) has been widely accepted as an explanation for a difference between the trolley and footbridge dilemmas (Thomson, 1985 Thomson, J. J. 1985. “The trolley problem”. In Ethics: Problems and principles, Edited by: Fischer, J. M. and Ravizza, M. Fort Worth, TX: Harcourt Brace Jovanovich.  [Google Scholar]), its psychometric properties remain a mystery. In this study 219 participants completed 62 moral dilemma tasks used in Greene et al. (2001 Greene, J. D., Sommerville, R. B., Nystrom, L. E., Darley, J. M. and Cohen, J. D. 2001. An fMRI investigation of emotional engagement in moral judgement. Science, 293: 2105–2108. doi:10.1126/science.1062872.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]), and the correlation structure among the dilemmas was analysed through factor analysis and structural equation modelling. Findings suggest that, first, moral-personal dilemmas are composed of one factor, indicating that the assumption in Greene et al. (2001 Greene, J. D., Sommerville, R. B., Nystrom, L. E., Darley, J. M. and Cohen, J. D. 2001. An fMRI investigation of emotional engagement in moral judgement. Science, 293: 2105–2108. doi:10.1126/science.1062872.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) was supported. Second, moral-impersonal dilemmas are explained by two factors that reflect procedural and consequential aspects of decision making. Third, the trolley and footbridge dilemmas fall under the same factor category; therefore the difference between the two dilemmas cannot be attributed to emotional involvement. Additionally, the results of the structural equation modelling suggest that they differ in the engagement of rational processing.     

Examining Current Conceptualizations of Psychopathology With the MMPI–2/MMPI–2–RF Restructured Clinical Scales: Preliminary Findings From a Cross-Cultural Study

Watson (2005 Watson, D. (2005). Rethinking the mood and anxiety disorders: A quantitative hierarchical model for DSM–V. Journal of Abnormal Psychology, 114, 522–536.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) proposed a hierarchical reorganization of the underlying structure of emotional disorders. This study cross-culturally evaluated Watson's (2005) structure of mood and anxiety disorders, using mainly dichotomous criteria, and explored the placement of obsessive–compulsive disorder (OCD) in this model. It also tested Sellbom, Ben-Porath, and Bagby's (2008) proposed elaboration of the 2-factor model (positive and negative activation) that incorporates a higher order dimension of demoralization. One hundred men and 133 women from psychiatric settings in Israel completed the Minnesota Multiphasic Personality Inventory–2 (Butcher et al., 2001 Butcher, J. N., Graham, J. R., Ben-Porath, Y. S., Tellegen, A., Dahlstrom, W. G., &; Kaemmer, B. (2001). Minnesota Multiphasic Personality Inventory–2 (MMPI–2): Manual for administration, scoring and interpretation (Rev. ed.). Minneapolis: University of Minnesota Press.[Crossref] , [Google Scholar]) and the Maudsley Obsessional–Compulsive Inventory (Hodgson &; Rachman, 1977 Hodgson, R. J., &; Rachman, S. (1977). Obsessive–compulsive complaints. Behaviour Research and Therapy, 15, 389–395.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). They were interviewed using the Mini International Neuropsychiatric Interview (Sheehan et al., 1998 Sheehan, D. V., Lecrubier, Y., Sheehan, K. H., Amorim, P., Janavs, J., &; Weiller, E. (1998). The Mini-International Neuropsychiatric Interview (M.I.N.I.): The development and validation of a structured diagnostic psychiatric interview for DSM–IV and ICD–10. Journal of Clinical Psychiatry, 59, 22–33.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). Confirmatory factor analyses replicated Watson's structure for women but not for men. Mixed results were obtained regarding OCD's location in the model. Findings among women support the applicability of Watson's (2005) model across a variety of assessment modalities, as well as in a different language and for diversified cultural backgrounds. This conclusion, however, should be tempered in consideration of the results among men. Findings also provide evidence of the importance of demoralization in mood and anxiety disorders.     

Commentary Research on gene–environment interdependence: Honing the tools and examining the angles

The insightful overview by Sir Michael Rutter (this issue) on gene–environment interdependence comes about 10 years after the breakthrough Science publications on gene–environment interactions (G×E) involving the MAOA and 5-HTT genes by Caspi et al. (2002 Caspi, A., McClay, J., Moffitt, T. E., Mill, J., Martin, J.Craig, I. W. 2002. Role of genotype in the cycle of violence in maltreated children. Science, 297: 851–854. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar], 2003 Caspi, A., Sugden, K., Moffitt, T. E., Taylor, A., Craig, I. W.Harrington, H. 2003. Influence of life stress on depression: Moderation by a polymorphism in the 5-HTT gene. Science, 301: 386–389. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). Since then, a field of research has burgeoned that has produced replications as well as intriguing new evidence of gene–environment interdependence. At the same time, however, the field has witnessed a growing scepticism about the relevance of studying gene–environment interactions and has seen replication failures (see Duncan & Keller, 2011 Duncan, L. E. and Keller, M. C. 2011. A critical review of the first 10 years of candidate gene-by-environment interaction research in psychiatry. American Journal of Psychiatry, 168: 1041–1049. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]; Risch et al., 2009 Risch, N., Herell, R., Lehner, T., Liang, K.-Y., Eaves, L.Hoh, J. 2009.

[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). Against this backdrop, we comment and elaborate on several of the key issues raised by Rutter, and suggest some directions for future research on G×E. Specifically, we discuss (1) replication issues; (2) the crucial role of experiments in understanding gene–environment interdependence; (3) current unknowns with regard to differential susceptibility; and (4) clinical and practical implications of G×E research.     

Calibrated Bayes Factors Should Not Be Used: A Reply to Hoijtink,van Kooten,and Hulsker

Hoijtink, Kooten, and Hulsker (2016 Hoijtink, H., van Kooten, P., &; Hulsker, K. (2016). Why Bayesian psychologists should change the way they use the Bayes factor. Multivariate Behavioral Research, 51, 1--9. doi: 10.1080/00273171.2014.969364.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) present a method for choosing the prior distribution for an analysis with Bayes factor that is based on controlling error rates, which they advocate as an alternative to our more subjective methods (Morey &; Rouder, 2014 Morey, R.D., &; Rouder, J.N.

Journal of Personality and Social Psychology, 100, 426–432. doi: 10.1037/a0022790[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). We show that the method they advocate amounts to a simple significance test, and that the resulting Bayes factors are not interpretable. Additionally, their method fails in common circumstances, and has the potential to yield arbitrarily high Type II error rates. After critiquing their method, we outline the position on subjectivity that underlies our advocacy of Bayes factors.     

Inter-word eye behaviour during reading is not invariant to character size: Evidence against systematic saccadic range error in reading

The present study re-investigated the effect of character size on eye behaviour during reading, in order to test McConkie, Kerr, Reddix, and Zola's (1988 McConkie, G. W., Kerr, P. W., Reddix, M. D., & Zola, D. (1988). Eye movement control during reading: I. The location of initial eye fixations on words. Vision Research, 28(10), 1107–1118. doi:10.1016/0042-6989(88)90137-X[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) Saccadic Range Error (SRE) hypothesis. This assumes that saccades are biased to move the eyes a constant, optimal distance in the task (i.e., range error), while aiming at the centre of peripherally selected target words. Results showed in contradiction with this hypothesis, (1) that the linear relationship between the eye launch site and the mean landing sites in words is not invariant to character size, and (2) that the optimal launch-site distance to the centre of words varies depending on the spatial extent of the words, and differs from the mean length of saccades in the task. We propose an alternative, Center-of-Gravity hypothesis, which a priori accounts for the launch-site effect and its variations with character size, and suggests that research in reading may benefit from reconsidering the role of character size.     

Model Conditioned Data Elasticity in Path Analysis: Assessing the “Confoundability” of Model/Data Characteristics

Much research has been directed at the validity of fit indices in Path Analysis and Structural Equation Modeling (e.g., Browne, MacCallum, Kim, Andersen, &; Glaser, 2002 Browne, M.W., MacCallum, R.C., Kim, C.T., Andersen, B.L., &; Glaser, R.

Reply to Rodgers and Rowe (2002). Psychological Review, 109(3), 605–607.[Crossref] , [Google Scholar]) have encouraged researchers to investigate other criteria for comparing models, including model complexity. What has not been investigated is the inherent ability of a particular data set to be fitted with a constrained set of randomly generated linear models, which we call Model Conditioned Data Elasticity (DE). In this article we show how DE can be compared with the problem of equivalent models and a more general problem of the “confoundability” of data/model combinations (see MacCallum, Wegener, Uchino, &; Fabrigar, 1993 MacCallum, R.C., Wegener, D.T., Uchino, B.N., &; Fabrigar, L.R. (1993). The problem of equivalent models in applications of covariance structure analysis. Psychological Bulletin, 114(1), 185–199.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). Using the DE package in R, we show how DE can be assessed through automated computer searches. Finally, we discuss how DE fits within the controversy surrounding the use of fit statistics.     

Introducing a Bayesian Approach to Determining Degree of Fit With Existing Rorschach Norms

This article offers a new methodological approach to investigate the degree of fit between an independent sample and 2 existing sets of norms. Specifically, with a new adaptation of a Bayesian method, we developed a user-friendly procedure to compare the mean values of a given sample to those of 2 different sets of Rorschach norms. To illustrate our technique, we used a small, U.S. community sample of 80 adults and tested whether it resembled more closely the standard Comprehensive System norms (CS 600; Exner, 2003), or a recently introduced, internationally based set of Rorschach norms (Meyer, Erdberg, & Shaffer, 2007 Meyer, G. J., Erdberg, P., & Shaffer, T. W. (2007). Toward international normative reference data for the Comprehensive System. Journal of Personality Assessment, 89(Suppl. 1), S201–S216.[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]). Strengths and limitations of this new statistical technique are discussed.

Leg Perception of Object Heaviness

ABSTRACT

Perceived heaviness is a function of both the muscle activity used to wield an object and the resulting movement. Wielding reveals invariant properties of the effector-object system, such as rotational inertia. Recent research has proposed a psychophysiological mechanism for perceiving the heaviness of a handheld object through dynamic touch that captures how arm muscle activity and angular movement combined reveal this invariance (Waddell, Fine, Likens, Amazeen & Amazeen, 2016 Waddell, M. L., Fine, J. M., Likens, A. D., Amazeen, E. L., & Amazeen, P. G. (2016). Perceived heaviness in the context of Newton's Second Law: Combined effects of muscle activity and lifting kinematics. Journal of Experimental Psychology: Human Perception and Performance, 42, 363–374.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). The current study extends this hypothesis by investigating the dynamics of heaviness perception with the leg. Participants lifted objects of varying mass with knee extension lifts while reporting perceived heaviness. During each lift, the electromyogram (EMG) was recorded from the quadriceps, and peak angular acceleration was recorded about the knee. The resulting psychophysiological function revealed the hypothesized ratio of muscle activity to movement, similar to that found in Waddell et al. (2016) Waddell, M. L., Fine, J. M., Likens, A. D., Amazeen, E. L., & Amazeen, P. G. (2016). Perceived heaviness in the context of Newton's Second Law: Combined effects of muscle activity and lifting kinematics. Journal of Experimental Psychology: Human Perception and Performance, 42, 363–374.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]. This suggests that the dynamics for heaviness perception in the leg is similar to that shown in the arm in previous work.     

Causal,A Priori True,and Explanatory: A Reply to Lange and Rosenberg

Sober [2011 Sober, E. 2011. A Priori Causal Models of Natural Selection, Australasian Journal of Philosophy 89/4: 571–89.[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]] argues that some causal statements are a priori true and that a priori causal truths are central to explanations in the theory of natural selection. Lange and Rosenberg [2011 Lange, M. and Rosenberg, A. 2011. Can There Be A Priori Causal Models of Natural Selection? Australasian Journal of Philosophy 89/4: 591–9.[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]] criticize Sober's argument. They concede that there are a priori causal truths, but maintain that those truths are only ‘minimally causal’. They also argue that explanations that are built around a priori causal truths are not causal explanations, properly speaking. Here we criticize both of Lange and Rosenberg's claims.     

Amplitude and Width Manipulations in Fitts' Paradigm: Comment on Heath et al. (2011) and Heath et al. (2016)

Heath, Weiler, Marriott, Elliott, and Binstead (2011 Heath, M., Weiler, J., Marriott, K. A., Elliott, D., &; Binstead, G. (2011). Revisiting Fitts and Peterson (1964): Width and Amplitude manipulations to the reaching environment elicit dissociable movement times. Canadian Journal of Experimental Psychology, 65, 259–268.1.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) and Heath, Samani, Tremblay, and Elliott (2016 Heath, M., Samani, A., Tremblay, L., &; Elliott, D. (2016). Fitts' theorem in oculomotor control: Dissociable movement times for amplitude and width manipulations. Journal of Motor Behavior, 48, 489–499.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) have claimed that there are dissociable movement times for amplitude and width manipulations in the Fitts' paradigm. This may to some extent be true, but the Heath et al. (2011 Heath, M., Weiler, J., Marriott, K. A., Elliott, D., &; Binstead, G. (2011). Revisiting Fitts and Peterson (1964): Width and Amplitude manipulations to the reaching environment elicit dissociable movement times. Canadian Journal of Experimental Psychology, 65, 259–268.1.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) and Heath et al. (2016 Heath, M., Samani, A., Tremblay, L., &; Elliott, D. (2016). Fitts' theorem in oculomotor control: Dissociable movement times for amplitude and width manipulations. Journal of Motor Behavior, 48, 489–499.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) data do not support that contention, as shown in this comment. It is shown that data from the research of Heath et al. is not in the range of index of difficulty where ongoing visual control would be used and hence their fits of data to Fitts' law are spurious. The data of Heath et al. (2011 Heath, M., Weiler, J., Marriott, K. A., Elliott, D., &; Binstead, G. (2011). Revisiting Fitts and Peterson (1964): Width and Amplitude manipulations to the reaching environment elicit dissociable movement times. Canadian Journal of Experimental Psychology, 65, 259–268.1.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) for arm movements and for the primary eye saccade submovements of Heath et al. (2016 Heath, M., Samani, A., Tremblay, L., &; Elliott, D. (2016). Fitts' theorem in oculomotor control: Dissociable movement times for amplitude and width manipulations. Journal of Motor Behavior, 48, 489–499.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) are well correlated by the ballistic movement time equation of Hoffmann (1981 Hoffmann, E. R. (1981). An ergonomic approach to predetermined motion time systems. Proceedings of the 9th National Conference of the Institute of Industrial Engineers, Australia, 30–47. [Google Scholar]) and Gan and Hoffmann (1988 Gan, K.-C. &; Hoffmann, E. R. (1988). Geometrical conditions for ballistic and visually controlled movements. Ergonomics, 31, 829–839.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]). When the ballistic equation is used to model data for constant amplitude and constant target width conditions, the effects of the amplitude and width manipulations disappear. Other research indicates that the independent effects of movement amplitude occur due to changes in the time for the distance-covering phase of the movement.     

Modality effects in memory for basic stimulus attributes: A temporal and nontemporal comparison

Previous research suggests that there are significant differences in the operation of reference memory for stimuli of different modalities, with visual temporal entries appearing to be more durable than auditory entries (Ogden, Wearden, & Jones, 2008 Ogden, R. S., Wearden, J. H. and Jones, L. A. 2008. The remembrance of times past: Interference in temporal reference memory. Journal of Experimental Psychology: Human Perception and Performance, 34: 1524–1544. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar], 2010). Ogden et al. (2008 Ogden, R. S., Wearden, J. H. and Jones, L. A. 2008. The remembrance of times past: Interference in temporal reference memory. Journal of Experimental Psychology: Human Perception and Performance, 34: 1524–1544. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar], 2010 Ogden, R. S., Wearden, J. H. and Jones, L. A. 2010. Are memories for duration modality specific?. Quarterly Journal of Experimental Psychology, 63: 65–80. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) demonstrated that when participants were required to store multiple auditory temporal standards over a period of delay there was significant systematic interference to the representation of the standard characterized by shifts in the location of peak responding. No such performance deterioration was observed when multiple visually presented durations were encoded and maintained. The current article explored whether this apparent modality-based difference in reference memory operation is unique to temporal stimuli or whether similar characteristics are also apparent when nontemporal stimuli are encoded and maintained. The modified temporal generalization method developed in Ogden et al. (2008) Ogden, R. S., Wearden, J. H. and Jones, L. A. 2008. The remembrance of times past: Interference in temporal reference memory. Journal of Experimental Psychology: Human Perception and Performance, 34: 1524–1544. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar] was employed; however, standards and comparisons varied by pitch (auditory) and physical line length (visual) rather than duration. Pitch and line length generalization results indicated that increasing memory load led to more variable responding and reduced recognition of the standard; however, there was no systematic shift in the location of peak responding. Comparison of the results of this study with those of Ogden et al. (2008 Ogden, R. S., Wearden, J. H. and Jones, L. A. 2008. The remembrance of times past: Interference in temporal reference memory. Journal of Experimental Psychology: Human Perception and Performance, 34: 1524–1544. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar], 2010 Ogden, R. S., Wearden, J. H. and Jones, L. A. 2010. Are memories for duration modality specific?. Quarterly Journal of Experimental Psychology, 63: 65–80. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) suggests that although performance deterioration as a consequence of increases in memory load is common to auditory temporal and nontemporal stimuli and visual nontemporal stimuli, systematic interference is unique to auditory temporal processing.     

The Structure of Multidimensional Perfectionism: Support for a Bifactor Model With a Dominant General Factor

Evidence suggests perfectionism is a multidimensional construct composed of 2 higher order factors: perfectionistic strivings and perfectionistic concerns. However, the substantial overlap between perfectionistic strivings and perfectionistic concerns is problematic, as are the unanswered questions regarding the structure of perfectionism following removal of common variance. This research addressed this through bifactor modeling. Three student samples (N = 742) completed Hewitt and Flett's (1991 Hewitt, P. L., &; Flett, G. L. (1991). Perfectionism in the self and social contexts: Conceptualization, assessment, and association with psychopathology. Journal of Personality and Social Psychology, 60, 456.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) Multidimensional Perfectionism Scale, Frost, Marten, Lahart, and Rosenblate's (1990 Frost, R. O., Marten, P., Lahart, C., &; Rosenblate, R. (1990). The dimensions of perfectionism. Cognitive Therapy and Research, 14, 449–468.[Crossref], [Web of Science ®] , [Google Scholar]) Multidimensional Perfectionism Scale, and Slaney, Rice, Mobley, Trippi, and Ashby's (2001 Slaney, R. B., Rice, K. G., Mobley, M., Trippi, J., &; Ashby, J. S. (2001). The revised almost perfect scale. Measurement and Evaluation in Counseling and Development, 34, 130–145.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) Almost Perfect Scale–Revised. Greater support was consistently found for the bifactor model, relative to the 2-factor model. Results suggest the bifactor model best represents the structure of perfectionism and provide preliminary support for the use of a general factor score. Researchers are cautioned that removal of general variance may render the reliability of specific factors (i.e., perfectionistic strivings and perfectionistic concerns) suspect.     

Unmasking a shady mirror effect: Recognition of normal versus obscured faces

Hockley, Hemsworth, and Consoli (1999) Hockley, W. E., Hemsworth, D. E. and Consoli, A. 1999. Shades of the mirror effect: Recognition of faces with and without sunglasses. Memory & Cognition, 27: 128–138. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar] found that following the study of normal faces, a recognition test of normal faces versus faces wearing sunglasses produced a mirror effect: The sunglasses manipulation decreased hit rates and increased false-alarm rates. The stimuli used by Hockley et al. (1999) Hockley, W. E., Hemsworth, D. E. and Consoli, A. 1999. Shades of the mirror effect: Recognition of faces with and without sunglasses. Memory & Cognition, 27: 128–138. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar] consisted of separate poses of models wearing or not wearing sunglasses. In the current experiments, we separately manipulated same versus different depictions of individual faces and whether or not the faces were partially obscured. The results of a simulation and four experiments suggest that the test-based, mirror effect observed by Hockley et al. (1999) Hockley, W. E., Hemsworth, D. E. and Consoli, A. 1999. Shades of the mirror effect: Recognition of faces with and without sunglasses. Memory & Cognition, 27: 128–138. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar] is actually two separable effects.     

A sentence completion procedure as an alternative to the Autobiographical Memory Test for assessing overgeneral memory in non-clinical populations

Overgeneral memory (OGM) has been proposed as a vulnerability factor for depression (Williams et al., 2007 Williams , J. M. G. , Barnhofer , T. , Crane , C. , Hermans , D. , Raes , F. , Watkins , E. , & Dalgleish , T. ( 2007 ). Autobiographical memory specificity and emotional disorder . Psychological Bulletin , 133 , 122 – 148 .[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) or depressive reactivity to stressful life-events (e.g., Gibbs & Rude, 2004 Gibbs, B. R. and Rude, S. S. 2004. Overgeneral autobiographical memory as depression vulnerability. Cognitive Therapy and Research, 28: 511–526. [Crossref], [Web of Science ®] , [Google Scholar]). Traditionally, a cue word procedure known as the Autobiographical Memory Test (AMT; Williams & Broadbent, 1986 Williams, J. M. G. and Broadbent, K. 1986. Autobiographical memory in suicide attempters. Journal of Abnormal Psychology, 95: 144–149. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) is used to assess OGM. Although frequently and validly used in clinical populations, there is evidence suggesting that the AMT is insufficiently sensitive to measure OGM in non-clinical groups. Study 1 evaluated the usefulness of a sentence completion method to assess OGM in non-clinical groups, as an alternative to the AMT. Participants were 197 students who completed the AMT, the Sentence Completion for Events from the Past Test (SCEPT), a depression measure, and visual analogue scales assessing ruminative thinking. Results showed that the mean proportion of overgeneral responses was markedly higher for the SCEPT than for the standard AMT. Also, overgeneral responding on the SCEPT was positively associated to depression scores and depressive rumination scores, whereas overgeneral responding on the AMT was not. Results suggest that the SCEPT, relative to the AMT, is a more sensitive instrument to measure OGM, at least in non-clinical populations. Study 2 further showed that this enhanced sensitivity is most likely due to the omission of the instruction to be specific rather than to the SCEPT's sentence completion format (as opposed to free recall to cue words).     

A Cross-Cultural Analysis of the Infant Behavior Questionnaire Very Short Form: An Item Response Theory Analysis of Infant Temperament in New Zealand

The Infant Behavior Questionnaire–Revised Very Short Form (IBQ–R VSF; Putnam, Helbig, Gartstein, Rothbart, &; Leerkes, 2014 Putnam, S. P., Helbig, A. L., Gartstein, M. A., Rothbart, M. K., &; Leerkes, E. (2014). Development and assessment of short and very short forms of the Infant Behavior Questionnaire–Revised. Journal of Personality Assessment, 96, 445–458. doi:10.1080/00223891.2013.841171[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) is a newly published measure of infant temperament with a 3-factor structure. Recently Peterson et al. (2017 Peterson, E. R., Waldie, K. E., Mohal, J., Reese, E., Atatoa Carr, P.E., Grant, C. C., &; Morton, S. M. B. (2017). Infant Behavior Questionnaire–Revised Very Short Form: A new factor structure's associations with parenting perceptions and child language outcomes. Journal of Personality Assessment. Advance online publication. doi:10.1080/00223891.2017.1287709[Taylor &; Francis Online] , [Google Scholar]) suggested that a 5-factor structure (Positive Affectivity/Surgency, Negative Emotionality, Orienting Capacity, Affiliation/Regulation, and Fear) was more parsimonious and showed promising reliability and predictive validity in a large, diverse sample. However, little is known about the 5-factor model's precision across the temperament dimensions range and whether it discriminates equally well across ethnicities. A total of 5,567 mothers responded to the IBQ–R VSF in relation to their infants (N = 5,639) between 23 and 52 weeks old. Using item response theory, we conducted a series of 2 parameter logistic item response models and found that 5 IBQ–R VSF temperament dimensions showed a good distribution of estimates across each latent trait range and these estimates centered close to the population mean. The IBQ–R VSF was also similarly precise across 4 ethnic groups (European, Māori, Pacific peoples, and Asians), suggesting that it can be used as comparable measure for infant temperament in a diversity of ethnic groups.     

Bayes Factors Have Frequency Properties—This Should Not Be Ignored: A Rejoinder to Morey,Wagenmakers, and Rouder

Why we simulate negated information: A dynamic pragmatic account

A well-established finding in the simulation literature is that participants simulate the positive argument of negation soon after reading a negative sentence, prior to simulating a scene consistent with the negated sentence (Kaup, Lüdtke, & Zwaan, 2006 Kaup, B., Lüdtke, J. and Zwaan, R. A. 2006. Processing negated sentences with contradictory predicates: Is a door that is not open mentally closed?. Journal of Pragmatics, 38: 1033–1050. [Crossref], [Web of Science ®] , [Google Scholar]; Kaup, Yaxley, Madden, Zwaan, & Lüdtke, 2007 Kaup, B., Yaxley, R. H., Madden, C. J., Zwaan, R. A. and Lüdtke, J. 2007. Experiential simulations of negated text information. Quarterly Journal of Experimental Psychology, 60: 976–990. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]). One interpretation of this finding is that negation requires two steps to process: first represent what is being negated then “reject” that in favour of a representation of a negation-consistent state of affairs (Kaup et al., 2007 Kaup, B., Yaxley, R. H., Madden, C. J., Zwaan, R. A. and Lüdtke, J. 2007. Experiential simulations of negated text information. Quarterly Journal of Experimental Psychology, 60: 976–990. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]). In this paper we argue that this finding with negative sentences could be a by-product of the dynamic way that language is interpreted relative to a common ground and not the way that negation is represented. We present a study based on Kaup et al. (2007) Kaup, B., Yaxley, R. H., Madden, C. J., Zwaan, R. A. and Lüdtke, J. 2007. Experiential simulations of negated text information. Quarterly Journal of Experimental Psychology, 60: 976–990. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar] that tests the competing accounts. Our results suggest that some negative sentences are not processed in two steps, but provide support for the alternative, dynamic account.
