Spoken Language Outcomes after Hemispherectomy: Factoring in Etiology

We analyzed postsurgery linguistic outcomes of 43 hemispherectomy patients operated on at UCLA. We rated spoken language (Spoken Language Rank, SLR) on a scale from 0 (no language) to 6 (mature grammar) and examined the effects of side of resection/damage, age at surgery/seizure onset, seizure control postsurgery, and etiology on language development. Etiology was defined as developmental (cortical dysplasia and prenatal stroke) and acquired pathology (Rasmussen's encephalitis and postnatal stroke). We found that clinical variables were predictive of language outcomes only when they were considered within distinct etiology groups. Specifically, children with developmental etiologies had lower SLRs than those with acquired pathologies (p =.0006); age factors correlated positively with higher SLRs only for children with acquired etiologies (p =.0006); right-sided resections led to higher SLRs only for the acquired group (p =.0008); and postsurgery seizure control correlated positively with SLR only for those with developmental etiologies (p =.0047). We argue that the variables considered are not independent predictors of spoken language outcome posthemispherectomy but should be viewed instead as characteristics of etiology.     

The Effects of Scrambling on Spanish and Korean Agrammatic Interpretation: Why Linear Models Fail and Structural Models Survive

Several models of comprehension deficits in agrammatic aphasia rely heavily on linear considerations in the assignment of thematic roles to structural positions (e.g., the Trace-Deletion Hypothesis, the Mapping Hypothesis, and the Argument-Linking Hypothesis). These accounts predict that constructions in languages with rules that affect syntactic structure but preserve relative linear order should be unimpaired. Other models [e.g., the Double-Dependency Hypothesis, (DDH)] do not resort to linearity but are purely structural in conception and therefore should be immune to word-order effects. We tested linear and nonlinear accounts with scrambling structures in Korean and topicalization structures in Spanish. The results are very clear. The (nonlinear) DDH is entirely compatible with the evidence, but the linear accounts are not.     

Phonology: A Review and Proposals from a Connectionist Perspective

A parallel distributed processing (PDP) model of phonological processing is developed, including components to support repetition, auditory processing, comprehension, and language production. From the performance of the PDP reading model of Plaut, McClelland, Seidenberg, and Patterson (1996), it is inferred that the acoustic-articulatory motor pattern associator that supports repetition provides the basis for phonological sequence knowledge. From the observation that many patients make phonemic paraphasic errors in language production, as in repetition, it is argued that there must be a direct link between distributed concept representations (lexical semantic knowledge) and this network representation of sequence knowledge. In this way, both lexical semantic and phonotactic constraints are brought to bear on language production. The literature on phonological function in normal subjects (slip-of-the-tongue corpora) and in patients with aphasia is critically reviewed from this perspective. The relationship between acoustic and articulatory motor representations in the process of phonetic perception is considered. Repetition and reproduction conduction aphasia are reviewed in detail and extended consideration is given to the representation of auditory verbal short-term memory in the model. Finally, the PDP model is reconciled with information processing models of phonological processing, including that of Lichtheim, and with current knowledge of the anatomic localization of phonological processing. Although no simulations of the model were run, a number of simulation studies are proposed.     

Maternal Personality and Distress as Predictors of Child Neglect

Previous studies suggest that maternal personality problems predict child neglect. However, these studies have not distinguished between the common and unique contributions of various maternal personality dimensions, nor have they compared the contribution of maternal personality with maternal emotional distress. The current study addresses these issues using data collected by James Gaudin and distributed by the National Data Archive on Child Abuse and Neglect at Cornell University. Information was extracted on 94 neglectful and 101 comparison mothers. Logistic regression analyses revealed that a composite score reflecting maternal empathic capacity inversely predicted child neglect, whereas maternal depressive symptoms and loneliness did not. Results are discussed in terms of the importance of distinguishing between common and unique contributions of maternal personality dimensions to clinical and social outcomes and in terms of the relative contribution of maternal personality and emotional distress to child neglect.     

The Effects of Positive Peer Reporting as a Class-Wide Positive Behavior Support

School-wide, selective, and individual positive behavioral supports are critical elements of a comprehensive, tiered model of service delivery. Positive peer reporting (PPR) involves brief, highly structured sessions during which peers are provided the opportunity to praise the behavior of target students. PPR procedures were modified in this study to provide all children in a classroom the opportunity to provide or receive peer praise. The effects of class-wide PPR on teacher-recorded critical events were evaluated using a multiple baseline design across two classrooms. Results indicated marginal improvement across the two settings, as well as supplemental measures of behavior outside of the classroom and class-wide sociometric nominations. Implications for future research and emerging models of school-wide PBS are discussed.     

Non-differential return of fear in humans after a reinstatement procedure

The present experiment investigated reinstatement of fear in humans using a differential fear conditioning preparation. In this experiment, one neutral stimulus (conditioned stimulus; CS+) was paired with an aversive stimulus (unconditioned stimulus; US) during the acquisition phase, while another neutral stimulus was not (CS−). This procedure led to a difference in responding between the CS+ and the CS− (i.e., differential conditioning). After this acquisition phase, an extinction phase followed, during which both CSs were presented without the US, resulting in a decrease in differential conditioned responding. Reinstatement refers to the return of extinguished conditioned responses due to the experience of US-only trials after the extinction phase. This phenomenon was investigated by presenting half of the participants (reinstatement group) with unpredictable USs after the extinction phase. The control group did not receive these USs after the extinction procedure. The results show that return of fear was clearly apparent after the reinstating USs. This return of fear was, however, not limited to the CS+. An increase in ‘conditioned’ responding was also observed for the control stimulus. This interesting observation will be discussed against the background of a number of recent theoretical conceptualizations of reinstatement.     

Asymmetric cross-modal effects in time perception

It is common to judge the duration of an audiovisual event, and yet it remains controversial how the judgment of duration is affected by signals from other modalities. We used an oddball paradigm to examine the effect of sound on the judgment of visual duration and that of a visual object on the judgment of an auditory duration. In a series of standards and oddballs, the participants compared the duration of the oddballs to that of the standards. Results showed asymmetric cross-modal effects, supporting the auditory dominance hypothesis: a sound extends the perceived visual duration, whereas a visual object has no effect on perceived auditory duration. The possible mechanisms (pacemaker or mode switch) proposed in the Scalar Expectancy Theory [Gibbon, J., Church, R. M., & Meck, W. H. (1984). Scalar timing in memory. In J. Gibbon & L. Allan (Eds.), Annals of the New York Academy of Sciences: Vol. 423. Timing and time perception (pp. 52–77). New York: New York Academy of Sciences] were examined using different standard durations. We conclude that sound increases the perceived visual duration by accelerating the pulse rate in the visual pacemaker.     

Analyse multitraits–multiméthodes des scores au Questionnaire d’attributs personnels (Personal attributes questionnaire [PAQ]) auprès d’un échantillon féminin

The present study examines convergent and discriminent validity of the scores on a French version of the Personal Attributes Questionnaire (PAQ) using confirmatory factor analysis of a multitrait–multimethod matrix. The convergent validity of self-rating scores on the PAQ and parent rating scores (i.e., mothers about their own daughters) on the Bem Sex-Role Inventory (BSRI) was satisfactory. Results revealed that the PAQ manifested significant discriminant validity. Although the factorial structure of the PAQ was confirmed, one item did not seem to be a good indicator of expressivity. Finally, the content validity of the PAQ was discussed.     

用“你”表述物体的功能会抑制成因对归类的影响

已有研究显示物体的成因等变量会影响人造物概念的分类;但这种影响的中介变量为何,基于设计和基于用途的理论有不同的假设。实验采用物体自由命名任务,在陈述物体的功能时,操纵角色词的类型（旁观者“有人”和使用者“你”）,比较被试对物体的命名在领域水平的分类倾向。结果发现,呈现“旁观者”角色词时,呈现或不呈现物体自然形成的成因故事会造成不同的分类倾向;但是在呈现“使用者”角色词时,成因故事对分类倾向的影响消失了。提示物体的功能是成因和分类的中介变量,支持基于用途的人造物分类模型     

Musical Naturalism in the Thought of JI Kang

Wei-Jin period is characterized by neo-Daoism (xuanxue 玄學), and JI Kang lived in the midst of this philosophical exploration. Adopting the naturalism of the Zhuangzi, Ji Kang expressed his socio-political concerns through the medium of music, which was previously regarded as having moral bearing and rectitude. Denying such rectitude became central for Ji Kang, who claimed that music was incapable of possessing human emotion, releasing it from the chains of Confucian ritualism. His investigation into the name and reality of musical expression gave music an “aesthetic turn” lacking in Qin and early Han thought, and by making use of concepts such as natural harmony and spontaneity, Ji Kang was able to turn away from the negative aesthetics of earlier thinkers such as He Yan and Wang Bi to one cherishing the naturalism espoused by Zhuangzi.
