Reconsidering the role of temporal order in spoken word recognition

Models of spoken word recognition assume that words are represented as sequences of phonemes. We evaluated this assumption by examining phonemic anadromes, words that share the same phonemes but differ in their order (e.g., sub and bus). Using the visual-world paradigm, we found that listeners show more fixations to anadromes (e.g., sub when bus is the target) than to unrelated words (well) and to words that share the same vowel but not the same set of phonemes (sun). This contrasts with the predictions of existing models and suggests that words are not defined as strict sequences of phonemes.     

The allure of status: high-status targets are privileged in face processing and memory

The current research tests the hypothesis that face processing is attuned to high-status faces. Across three experiments, faces of high-status targets were better recognized than faces of low-status targets. In Experiment 2, this memory advantage for high-status targets also extended to an attentional bias toward high-status targets and to stronger sociospatial memory (identity-location link) for high-status targets. Finally, Experiment 3 finds that high-status faces received more expert-style holistic processing than did low-status faces. This suggests that high-status faces also benefit more from the strategic deployment of expert face processing resources than low-status faces. Taken together, these data indicate that perceivers strategically allocate face processing resources to targets perceived to be high in status.     

The role of forget-cue salience in list-method directed forgetting

Research suggests that manipulating the wording of the forget cue in list-method directed forgetting affects the magnitude of directed forgetting both in younger children (Aslan, Staudigl, Samenieh, & Bauml, in press) and in older adults (Sahakyan, Delaney, & Goodmon, 2008). This occurs when the forget cue overemphasises the importance of forgetting in the current context. The present experiment investigated whether de-emphasising forgetting affected the magnitude of list-method directed forgetting in college adults. Some participants received overt forget cues that explicitly instructed them to forget earlier studied items, whereas others received covert forget cues that implied forgetting by emphasising selective remembering (e.g., "you will only need to remember some of the items"). Results indicated equivalent directed forgetting for both types of cues. However, regardless of the type of cue received, participants who reported using specific forgetting strategies in response to the forget cue showed directed forgetting, whereas those that reported doing nothing did not show any effects. The results underscore that successful directed forgetting requires engagement of controlled processes.     

Seeing wrath from the top (through stratified lenses): Perceivers high in social dominance orientation show superior anger identification for high-status individuals

In this research, we test the hypothesis that social status will be an orienting cue to the identification of facial expressions of emotion, particularly angry expressions, especially for those who dispositionally believe that some societal groups should dominate others (Social dominance orientation; Pratto, Sidanius, Stallworth, & Malle, 1994). Using an emotion identification task, the expression of anger was identified with greater accuracy on high-status faces than low-status faces, but only for people who endorsed rigid social hierarchies (i.e., high SDO). Furthermore, people who did not endorse social hierarchies (i.e., low SDO) did not show a preference for high-status anger. Thus, the current findings provide a novel account of how social status can be an informative cue to the expression of anger in online perceptions, especially for those who view social dominance as an important framework for society.     

Development and psychometric evaluation of the Personal Growth Initiative Scale-II

The original Personal Growth Initiative Scale (PGIS; Robitschek, 1998) was unidimensional, despite theory identifying multiple components (e.g., cognition and behavior) of personal growth initiative (PGI). The present research developed a multidimensional measure of the complex process of PGI, while retaining the brief and psychometrically sound properties of the original scale. Study 1 focused on scale development, including theoretical derivation of items, assessing factor structure, reducing number of items, and refining the scale length using samples of college students. Study 2 consisted of confirmatory factor analysis with 3 independent samples of college students and community members. Lastly, Study 3 assessed test-retest reliability over 1-, 2-, 4-, and 6-week periods and tests of concurrent and discriminant validity using samples of college students. The final measure, the Personal Growth Initiative Scale-II (PGIS-II), includes 4 subscales: Readiness for Change, Planfulness, Using Resources, and Intentional Behavior. These studies provide exploratory and confirmatory evidence for the 4-factor structure, strong internal consistency for the subscales and overall score across samples, acceptable temporal stability at all assessed intervals, and concurrent and discriminant validity of the PGIS-II. Future directions for research and clinical practice are discussed.     

Parallel Factor Analysis of gait waveform data: A multimode extension of Principal Component Analysis

Gait data are typically collected in multivariate form, so some multivariate analysis is often used to understand interrelationships between observed data. Principal Component Analysis (PCA), a data reduction technique for correlated multivariate data, has been widely applied by gait analysts to investigate patterns of association in gait waveform data (e.g., interrelationships between joint angle waveforms from different subjects and/or joints). Despite its widespread use in gait analysis, PCA is for two-mode data, whereas gait data are often collected in higher-mode form. In this paper, we present the benefits of analyzing gait data via Parallel Factor Analysis (Parafac), which is a component analysis model designed for three- or higher-mode data. Using three-mode joint angle waveform data (subjects×time×joints), we demonstrate Parafac's ability to (a) determine interpretable components revealing the primary interrelationships between lower-limb joints in healthy gait and (b) identify interpretable components revealing the fundamental differences between normal and perturbed subjects' gait patterns across multiple joints. Our results offer evidence of the complex interconnections that exist between lower-limb joints and limb segments in both normal and abnormal gaits, confirming the need for the simultaneous analysis of multi-joint gait waveform data (especially when studying perturbed gait patterns).     

Limbic system dysfunction and inventoried psychopathology among incarcerated pedophiles

This study explored relationships between “highly probable” neuropathology in the limbic system (as gauged by clinically elevated scores on the Limbic System Check-list-33, or LSCL-33, a screening index for limbic system dysfunction developed by medical researchers at Harvard and Dartmouth) and inventoried psychopathology (as gauged through scores on the MMPI) among a group of adjudicated pedophiles incarcerated for treatment in a specialized prison for criminal sexual psychopaths in a mid-Atlantic state. Principal findings: Only 33 percent of this sample of incarcerated pedophiles exhibits scores on the LSCL-33 at a level high enough to warrant a medical conclusion of “probable” limbic system dysfunction. When scores on the MMPI are grouped according to critical values for clinically relevant scores on the LSCL-33, significant F ratios in one-way analyses of variance are observed on L, F, K, Hs, D, Hy, Pa, Pt, Sc, and Ma. Mean T scores for “probable” dysfunctionals simultaneously reach elevations at or above the threshold of clinical significance for Pd, Pa, and Sc. On that basis, the categorization psychopathic paranoid schizophrenia readily applies to limbic system dysfunctional child sexual abusers studied in this inquiry, but not to their nondysfunctional counterparts. But significant F ratios are observed neither for the age of the victim(s) in the instant offense(s), for the number of prior arrests for sex offenses, for the number of prior arrests for any and all felony offenses, including sex offenses, nor for the offender's current age. However, a stepwise multiple regression between gross number of prior arrests for any and all offenses (including sex offenses) as the most robust of the indices of past criminal activity and both LSCL-33 and MMPI scores across all offenders represented in this inquiry (i.e., the limbic system dysfunctional, the nondysfunctional, and a mid-range group) proceeds to four steps, achieving a multiple R of .575 and encompassing Pd, Mf, Pa, and LSCL-33 scores as the most efficient interactive post-dictive set. Stepwise multiple regression analyses of past arrest record computed independently for limbic system dysfunctionals and nondysfunctionals progresses among dysfunctionals to seven steps, achieving a multiple R of .867 and encompassing Pd, Hy, Ma, Mf, Si, Pa, and Sc scores as the most efficient interactive post-dictive set; and among nondysfunctionals, to six steps, achieving a multiple R of .797 and encompassing Mf, D, Pt, Hy, Pa, and over-controlled hostility scores as the most efficient interactive post-dictive set. The latter results are interpreted as suggesting that neuropathology and psychopathology interact with and potentiate each other in post-dicting criminal behavior among the pedophiles studied in this inquiry. This study was supported in part by the Fund for Correctional and Forensic Psychology, Rutgers University Foundation. The investigators express deep appreciation to Charles Albino for assis-tance in data collection.     

Tension within Triangulation

Philosophers disagree about how meaning connects with history. Donald Davidson, who helped deepen our understanding of meaning, even disagreed with himself. As Ernest Lepore and Kirk Ludwig note, Davidson's account of radical interpretation treats meaning as ahistorical; his Swampman thought experiment treats it as historical. Here I show that while Lepore and Ludwig are right that Davidson's views are in tension, they are wrong about its extent. Unbeknownst to them, Davidson's account of radical interpretation and Swampman thought experiment both rely—in different ways—on the same model of triangulation. I revise one of those ways to resolve the tension within Davidson's views. I close by detailing what role history should play in Davidson's views overall.     

Maternal borderline personality disorder symptoms and adolescent psychosocial functioning

Borderline personality disorder (BPD) is characterized by severe disruption of interpersonal relationships, yet very little research has examined the relationship between maternal BPD and offspring psychosocial functioning. The present study examined 815 mothers and their 15-year-old children from a community-based sample to determine (1) if there is an association between mothers' BPD symptoms and the interpersonal functioning, attachment cognitions, and depressive symptoms of their offspring, and (2) if the association of maternal BPD and youth outcomes is independent of maternal and youth depression. Measures of youth psychosocial functioning included self, mother, interviewer rated, and teacher reports. Results indicated that there was a significant association between maternal BPD symptoms and youth outcomes, and that this association remained even after controlling for maternal lifetime history of major depression, maternal history of dysthymic disorder, and youth depressive symptoms. This study provides some of the first empirical evidence for a link between mother's BPD symptoms and youth psychosocial outcomes.
