Investigating Conversational Dynamics: Interactive Alignment,Interpersonal Synergy,and Collective Task Performance

This study investigates interpersonal processes underlying dialog by comparing two approaches, interactive alignment and interpersonal synergy, and assesses how they predict collective performance in a joint task. While the interactive alignment approach highlights imitative patterns between interlocutors, the synergy approach points to structural organization at the level of the interaction—such as complementary patterns straddling speech turns and interlocutors. We develop a general, quantitative method to assess lexical, prosodic, and speech/pause patterns related to the two approaches and their impact on collective performance in a corpus of task‐oriented conversations. The results show statistical presence of patterns relevant for both approaches. However, synergetic aspects of dialog provide the best statistical predictors of collective performance and adding aspects of the alignment approach does not improve the model. This suggests that structural organization at the level of the interaction plays a crucial role in task‐oriented conversations, possibly constraining and integrating processes related to alignment.     

Gender and its contribution to the prediction of cognitive abilities at 5 years

Gender-related differences in the prediction of five year-olds' cognitive abilities from measures of distal environment, proximal environment and infant test scores were examined in a random sample of 93 boys and 90 girls. Distal environmental data included maternal IQ, maternal and paternal education. Proximal environmental data included two variables derived from the Home Screening Questionnaire: the Home Questions and the Toy Checklist. The Bayley MDI was administered at age 13 months, whereas WPPSI-R was used as cognitive outcome measure at age 5 years. The relationship between paternal education and child IQ, and between proximal environmental variables and child IQ was significantly stronger for boys than for girls. The associations between proximal environment and IQ in boys, were accounted for by the distal environmental variables. Bayley MDI correlated significantly higher with girls' IQ compared to boys' IQ. Findings are discussed in terms of parental gender-differentiated socialization processes.     

A PHENOMENOLOGICAL APPROACH TO AUTOKINESIS

Analysis has shown that autokinesis constitutes a complex group of phenomena. Certain autokinetic movements ('paradoxical', i.e. experienced displacement without movement or vice versa) could not be adequately recorded by the 'tracing method', very often employed, or by other forms of purely physical registration. Autokinesis ought to be divided into a 'free' type (which may be 'paradoxical') and a 'restricted' type (always 'non-paradoxical'). 'Free' movements were experienced either in a plane perpendicular to the line of vision or as 'ad-ab' movements. 'Restricted' movements were described as either 'swinging' or 'undulating'.     

Development of the letter identity span in reading: evidence from the eye movement moving window paradigm

By means of the moving window paradigm, we examined how many letters can be identified during a single eye fixation and whether this letter identity span changes as a function of reading skill. The results revealed that 8-year-old Finnish readers identify approximately 5 characters, 10-year-old readers identify approximately 7 characters, and 12-year-old and adult readers identify approximately 9 characters to the right of fixation. Comparison with earlier studies revealed that the letter identity span is smaller than the span for identifying letter features and that it is as wide in Finnish as in English. Furthermore, the letter identity span of faster readers of each age group was larger than that of slower readers, indicating that slower readers, unlike faster readers, allocate most of their processing resources to foveally fixated words. Finally, slower second graders were largely not disrupted by smaller windows, suggesting that their word decoding skill is not yet fully automatized.     

Hierarchies in the Structure of Personality Traits

An emerging body of findings indicates that hierarchy is critical to integrating the Big Trait models – the Big Five, Big Four, Big Three, and Big Two – within a common structural framework. These findings, in addition to providing a unifying framework for understanding personality traits, confirm that hierarchy is an intrinsic and pervasive feature of trait structure. Here, fundamental concepts of trait hierarchies are reviewed, as is the empirical literature about hierarchies in personality trait structure. Important questions remain to be answered about the nature and form of hierarchies found in trait structure, as well as the methods used to understand them.     

Deaf hearing: Implicit discrimination of auditory content in a patient with mixed hearing loss

We describe a patient LS, profoundly deaf in both ears from birth, with underdeveloped superior temporal gyri. Without hearing aids, LS displays no ability to detect sounds below a fixed threshold of 60 dBs, which classifies him as clinically deaf. Under these no-hearing-aid conditions, when presented with a forced-choice paradigm in which he is asked to consciously respond, he is unable to make above-chance judgments about the presence or location of sounds. However, he is able to make above-chance judgments about the content of sounds presented to him under forced-choice conditions. We demonstrated that LS has faint sensations from auditory stimuli, but questionable awareness of auditory content. LS thus has a form of type-2 deaf hearing with respect to auditory content. As in the case of a subject with acquired deafness and deaf hearing reported on a previous occasion, LS’s condition of deaf hearing is akin in some respects to type-2 blindsight. As for the case of type 2 blindsight the case indicates that a form of conscious hearing can arise in the absence of a fully developed auditory cortex.     

Dominant paradigms in motor behavior research: the motor-action controversy revisited

In 1992, Abernethy and Sparrow published an evaluation of the historical development of the field of motor behavior research as published from 1977 up to 1988 in the Journal of Motor Behavior. The present study extends their evaluation from 1988 through 2005 using content analyses of articles on motor control and learning in this journal. Papers were categorized into the two dominant and contrasting paradigms, the motor systems approach and the action systems approach. Analysis suggests that the field of motor behavior research has changed considerably over the last three decades. The action systems approach is now the leading approach, but the motor systems approach has, however, not perished. In a Kuhnian perspective, the results might be consistent with a more long-lasting crisis, and from the available data it is not possible to predict a future outcome of the dispute between the two approaches.     

Construction, reconstruction, deconstruction: The fall of the Soviet Union from the point of view of conceptual history

The fall of the Soviet Union is analysed in conceptual terms, drawing on Reinhart Koselleck’s Begriffsgeschichte. The author seeks to interpret the instrumental role of the concepts perestrojka, glasnost′, reform, revolution, socialist pluralism, and acceleration in the Soviet collapse. The semantics and pragmatics are related to a wider intellectual and political context, and the conceptual perspective is used to help explain the progress of events. The author argues that the common notion of the reform policy concepts as clichés is not valid.

Understanding Psychopathology: Melding Behavior Genetics, Personality, and Quantitative Psychology to Develop an Empirically Based Model

ABSTRACT— Research on psychopathology is at a historical crossroads. New technologies offer the promise of lasting advances in our understanding of the causes of human psychological suffering. Making the best use of these technologies, however, requires an empirically accurate model of psychopathology. Much current research is framed by the model of psychopathology portrayed in current versions of the Diagnostic and Statistical Manual of Mental Disorders ( DSM ; American Psychiatric Association, 2000 ). Although the modern DSM s have been fundamental in advancing psychopathology research, recent research also challenges some assumptions made in the DSM —for example, the assumption that all forms of psychopathology are well conceived of as discrete categories. Psychological science has a critical role to play in working through the implications of this research and the challenges it presents. In particular, behavior-genetic, personality, and quantitative-psychological research perspectives can be melded to inform the development of an empirically based model of psychopathology that would constitute an evolution of the DSM .     

The principle of liberty and legal representation of posterity

This paper considers a guardianship model for the legal representation of future generations. According to this model, national and international courts should be given the competence to appoint guardians for future generations, if agents who care about the welfare of posterity apply for the creation of a guardianship in relation to a dispute that can be resolved by the application of law. This reform would grant guardians of future people legal standing or locus standi before courts, that is, the right to bring an action before a court of law for adjudication. Although the guardianship model faces several difficult theoretical and practical problems pertaining to the representation of different near and distant future generations, it is argued that this model – and certain other legal norms intended to protect future basic needs – can be justified on the basis of the principle of liberty.
