Effects of syllable structure in aphasic errors: implications for a new model of speech production

Current models of word production assume that words are stored as linear sequences of phonemes which are structured into syllables only at the moment of production. This is because syllable structure is always recoverable from the sequence of phonemes. In contrast, we present theoretical and empirical evidence that syllable structure is lexically represented. Storing syllable structure would have the advantage of making representations more stable and resistant to damage. On the other hand, re-syllabifications affect only a minimal part of phonological representations and occur only in some languages and depending on speech register. Evidence for these claims comes from analyses of aphasic errors which not only respect phonotactic constraints, but also avoid transformations which move the syllabic structure of the word further away from the original structure, even when equating for segmental complexity. This is true across tasks, types of errors, and, crucially, types of patients. The same syllabic effects are shown by apraxic patients and by phonological patients who have more central difficulties in retrieving phonological representations. If syllable structure was only computed after phoneme retrieval, it would have no way to influence the errors of phonological patients. Our results have implications for psycholinguistic and computational models of language as well as for clinical and educational practices.     

The Gendered Nature of Family Structure and Group-Based Anti-Egalitarianism: A Cross-National Analysis

Abstract

Using 4 samples of adolescents from 3 nations (Australia, Sweden, and the United States), the authors explored whether the gendered nature of the family socialization environment affected young people's level of group-based social egalitarianism. It was hypothesized that the greater the father's influence in the family, the greater the children's level of group-based social anti-egalitarianism. The results were consistent with the authors' expectations. Children from father-headed households had the highest level of group-based social anti-egalitarianism; children from mother-headed households had the lowest level of group-based anti-egalitarianism; and children from dual-parent households were in between. Similarly, children from homes in which the father had the greatest decision-making power tended to exhibit the highest levels of anti-egalitarianism, whereas children from homes in which the mother had the greatest decision-making power displayed the lowest levels of social anti-egalitarianism. Family structure did not interact with either the nationality or gender of the child.     

Attributions in the Evaluation of Alternative Solutions to Social Problems

Abstract

The influence of causal attributions in decision making was studied in two samples (one of grade- and high-school teachers and one of first-year university students in Santiago, Chile) who answered a two-part questionnaire about the relative importance of eight different causes of alcohol problems and the potential value of eight possible solutions to the problem. The evaluation of the probable effectiveness of each solution was used as the criterion variable in a multiple regression analysis that included, as regressors, the evaluation of the importance of the different causes and sex of the respondent. Results showed that the importance attributed to the cause it eliminated was always the best predictor of the value given to any solution in the student sample and most frequently among the members of the teacher sample, although the importance of other causes and sex of respondent also influenced it in most cases.     

The structure of acute stress disorder among Chinese adults exposed to an earthquake: Is dysphoric arousal a unique construct of acute posttraumatic responses?

Wang, R., Wang, L., Zhang, J., Liu, Z. & Wu, K. (2012). The structure of acute stress disorder among Chinese adults exposed to an earthquake: Is dysphoric arousal a unique construct of acute posttraumatic responses? Scandinavian Journal of Psychology 53, 430–436. As a diagnosis organized mainly on the basis of theoretical conceptualization, acute stress disorder (ASD) has been widely criticized for lack of empirical support since it was introduced into the DSM system. To address this issue, the present study investigated the latent structure of ASD symptoms measured by the Acute Stress Disorder Scale (ASDS). A total of 350 adults with a mean age of 32.9 years (SD = 14.0, range: 16–85) took part in this study 12 to 15 days after an earthquake. The results of confirmatory factor analyses showed that a five‐factor intercorrelated model (dissociation, reexperiencing, avoidance, dysphoric arousal, and anxious arousal) demonstrated the best data fit. The findings provide preliminary empirical evidence in favor of a new reconceptualization of ASD symptoms, and are informative for the impending DSM‐5.     

Prominence vs. aboutness in sequencing: A functional distinction within the left inferior frontal gyrus

Prior research on the neural bases of syntactic comprehension suggests that activation in the left inferior frontal gyrus (lIFG) correlates with the processing of word order variations. However, there are inconsistencies with respect to the specific subregion within the IFG that is implicated by these findings: the pars opercularis or the pars triangularis. Here, we examined the hypothesis that the dissociation between pars opercularis and pars triangularis activation may reflect functional differences between clause-medial and clause-initial word order permutations, respectively. To this end, we directly compared clause-medial and clause-initial object-before-subject orders in German in a within-participants, event-related fMRI design. Our results showed increased activation for object-initial sentences in a bilateral network of frontal, temporal and subcortical regions. Within the lIFG, posterior and inferior subregions showed only a main effect of word order, whereas more anterior and superior subregions showed effects of word order and sentence type, with higher activation for sentences with an argument in the clause-initial position. These findings are interpreted as evidence for a functional gradation of sequence processing within the left IFG: posterior subportions correlate with argument prominence-based (local) aspects of sequencing, while anterior subportions correlate with aboutness-based aspects of sequencing, which are crucial in linking the current sentence to the wider discourse. This proposal appears compatible with more general hypotheses about information processing gradients in prefrontal cortex (Koechlin & Summerfield, 2007).

Migrants' Integration in Western Europe: Bridging Social Psychology and Political Science

This article presents the possibilities and advantages of integrating social psychology and political science in the study of intergroup relations in diverse societies in Western Europe. Social psychology provides interesting insights in understanding the emotional and cognitive consequences of increased diversity. However, this literature tends to overlook the role of institutional discourses and correlated practices in stimulating or constraining positive intergroup relations. In order to fill these lacunae, the article suggests the integration of social psychology and a ‘political opportunity structure’ approach. This article maintains that the political opportunity structures operating in a context are not only important for understanding actors' mobilisation, as usually maintained in the literature, but also for studying the extent to which change at the micro‐level of social interaction can be stimulated or constrained. We illustrate the arguments of the article with an analysis of the narrative constructions and the correlated practices of integration as adopted by the city councils of Malmö and Bologna.

The reciprocal relationship between nonverbal behavior and sports performance in a cross-lagged panel model

ObjectivesThe aim of the present research is to investigate the relationship between nonverbal behavior (NVB) and sports performance in a longitudinal design using cross-lagged panel models (CLPMs).MethodIn our study NVB and performance were measured at eight time points (n₁) in 48 basketball matches (n₂), resulting in N = 384 data points. Cross-lagged paths between NVB and performance were analyzed in multilevel models, with NVB at time point t-1 predicting performance at time point t and performance at time point t-1 predicting NVB at time point t. Performance was measured as the score difference between one team to the opposing team within a time point. NVB was rated on a scale from dominance to submissiveness by two blinded raters. Dependence of performance measures between time points was eliminated by two different approaches, resulting in two different measurements of performance.ResultsResults indicate an effect of NVB at time point t-1 on performance at time point t for one of the methods of performance. Contrary to our hypothesis and evidence from previous findings, there was no effect of performance at time point t-1 on NVB at time point t for neither method of measuring performance.ConclusionsThis study supports a positive relationship between NVB and sports performance, more so in the direction of NVB predicting performance.     

Narcissistic Personality Inventory: Structure of the adapted Dutch version

Barelds, D. P. H. & Dijkstra, P. (2009). Narcissistic Personality Inventory: Structure of the adapted Dutch version. Scandinavian Journal of Psychology, 51, 132–138. The present study examined the structure of a Dutch adaptation of the 40‐item Narcissistic Personality Inventory ( Raskin & Terry, 1988 ) in a community sample (n = 460) and a student sample (n = 515). Altering the response format of the NPI to a Likert‐scale had no apparent effect on the responses. Confirmatory factor analyses supported neither the four‐factor structure reported by Emmons (1984) , nor the seven‐factor structure reported by Raskin and Terry (1988) . Instead, exploratory factor analyses supported either a single‐factor solution (general narcissism), or a two‐factor solution (Authority/Power and Self‐Admiration). The validity of the NPI was supported by its relations with sex, age, personality, self‐esteem, shame, guilt and social desirability.
