The interplay between language, gesture, and affect during communicative transition: a dynamic systems approach

From a dynamic systems perspective, transition points in development are times of increased instability, during which behavioral patterns are susceptible to temporary decoupling. This study investigated the impact of the vocabulary spurt on existing patterns of communicative coordination. Eighteen typically developing infants were videotaped at home 1 month before, at, and after the vocabulary spurt. Infants were identified as spurters if they underwent a discrete phase transition in vocabulary development (marked by an inflection point), and compared with a group of nonspurters whose word-learning rates followed a trajectory of continuous change. Relative to surrounding sessions, there were significant reductions in overall coordination of communicative behaviors and in words produced in coordination at the vocabulary spurt session for infants who experienced more dramatic vocabulary growth. In contrast, nonspurters demonstrated little change across sessions. Findings underscore the importance of transitions as opportunities for observing processes of developmental change.     

Differences and similarities in event recall and suggestibility between children and adults in Germany and the United States

Children (5-6 year olds, 7-8 year olds, 9-10 year olds) and adults from Germany and the United States were shown a brief video of a theft. One week later, participants were asked to give a free narrative of an observed event (free recall), followed either by sets of misleading or unbiased questions, and finally they were given a three-choice recognition question for each queried item. German participants of all ages had higher levels of correct free recall than did American participants. American adults and 9-10 year olds gave more correct responses to the open-ended unbiased questions than did their German counterparts. Germans of all ages made more correct responses to the misleading questions, whereas national differences, favoring the Germans, for incorrect response to misleading questions were restricted to the 5-6 year olds. National differences were interpreted as reflecting possible differences in strategic abilities, exposure to formal instruction, and the degree to which children experience self-directed, autonomous learning opportunities.     

Developmental kinesics: How children acquire communicative and non-communicative nonverbal behavior

This article is a position paper concerning the major issues in the study of children's acquistion of nonverbal behavior. In linguistic theory non-verbal behavior may be considered irrelevant, it may be condsidered the precursor of verbal language, or it may be viewed as an integral part of human communication which is verbal and nonverbal. The author opts for the latter theory. Concerning the relationship between what is innate and what is learned, the paper discusses that nonverbal expression is innate, but culture determines its forms and its uses. The paper then presents a brief history of Developmental Kinesics, explaining its technical difficulties and its methodological complexities. It proceeds by documenting the function of maternal nonverbal behavior towards the neonate. Finally, the paper treats the levels of analysis. A distinction is drawn between communicative and non-communicative nonverbal behavior. Its affective, emotional function relates to ego state; its regulatory function governs face-to-face interaction; and its referential, informative function pertains to the message proper. The child also acquires the non-interactional aspects of body movements which distinguish different peoples. Expression and perception must be studied separately; and finally, nonverbal behavior has to be correlated with verbal behavior and particular attention has to be focused on the double bind.     

Unity of analysis: similarities and differences in the analysis of children and grown-ups

When comparing child analysis with that of grown-ups, we are confronted with a substantial unity of psychoanalytic method, beyond the apparent differences. The more we consider the analysis as a here-and-now interaction between analyst and patient with transformative potential, the more age-dependent differences become blurred, and the specificity of a particular analytic couple acquires more significance. At the same time, what seems to be all the same--the actual patient before us--is quite different, with several components (the child, adolescent, and adult parts), implying a need to recognize the part we should address at any given point.     

Identifying similarities in cognitive subtest functional requirements: An empirical approach

In the cognitive test interpretation literature, a Rational/Intuitive, Indirect Empirical, or Combined approach is typically used to construct conceptual taxonomies of the functional (behavioral) similarities between subtests. To address shortcomings of these approaches, the functional requirements for 49 subtests from six individually administered scales of cognitive ability (WISC-IV, WPPSI-III, SB-V, WJ-III, CAS, and UNIT) were typed on index cards. Forty-eight (48) in-service and/or pre-service school psychologists were asked to sort the cards into two, three, five, or eight functionally similar piles. A multidimensional scaling analysis was performed on a 49 × 49 matrix of similarity scores collapsed across all 48 subjects. Three dimensions were extracted from the data: Reproduction of Stimuli Sequences versus Picture Viewing (Dimension 1), Timed Speed versus Untimed Power (Dimension 2), and Verbal versus Performance (Dimension 3). A hierarchical clustering procedure was then applied to the matrix data, and results were compared to previous categorization schemes identified in the test interpretation literature.     

On the structural similarities between worlds and times

In the debate about the nature and identity of possible worlds, philosophers have neglected the parallel questions about the nature and identity of moments of time. These are not questions about the structure of time in general, but rather about the internal structure of each individual time. Times and worlds share the following structural similarities: both are maximal with respect to propositions (at every world and time, either p or ～p is true, for every p); both are consistent; both are closed (every modal consequence of a proposition true at a world is also true at that world, and every tense-theoretic consequence of a proposition true at a time is also true at that time); just as there is a unique actual world, there is a unique present moment; and just as a proposition is necessarily true iff true at all worlds, a proposition is eternally true iff true at all times. In this paper, I show that a simple extension of my theory of worlds yields a theory of times in which the above structural similarities between the two are consequences.     

Cross-cultural differences and similarities in proneness to shame: An adaptationist and ecological approach

People vary in how easily they feel ashamed, that is, in their shame proneness. According to the information threat theory of shame, variation in shame proneness should, in part, be regulated by features of a person's social ecology. On this view, shame is an emotion program that evolved to mitigate the likelihood or costs of reputation-damaging information spreading to others. In social environments where there are fewer possibilities to form new relationships (i.e., low relational mobility), there are higher costs to damaging or losing existing ones. Therefore, shame proneness toward current relationship partners should increase as perceived relational mobility decreases. In contrast, individuals with whom one has little or no relationship history are easy to replace, and so shame-proneness towards them should not be modulated by relational mobility. We tested these predictions cross-culturally by measuring relational mobility and shame proneness towards friends and strangers in Japan, the United States, and the United Kingdom. Japanese subjects were more shame-prone than their British and American counterparts. Critically, lower relational mobility was associated with greater shame proneness towards friends (but not strangers), and this relationship partially mediated the cultural differences in shame proneness. Shame proneness appears tailored to respond to relevant features of one's social ecology.     

Using a multi‐feature paradigm to measure mismatch responses to minimal sound contrasts in children with cochlear implants and hearing aids

Our aim was to explore whether a multi‐feature paradigm (Optimum‐1) for eliciting mismatch negativity (MMN) would objectively capture difficulties in perceiving small sound contrasts in children with hearing impairment (HI) listening through their hearing aids (HAs) and/or cochlear implants (CIs). Children aged 5–7 years with HAs, CIs and children with normal hearing (NH) were tested in a free‐field setting using a multi‐feature paradigm with deviations in pitch, intensity, gap, duration, and location. There were significant mismatch responses across all subjects that were positive (p‐MMR) for the gap and pitch deviants (F(1,43) = 5.17, p = 0.028 and F(1,43) = 6.56, p = 0.014, respectively) and negative (MMN) for the duration deviant (F(1,43) = 4.74, p = 0.035). Only the intensity deviant showed a significant group interaction with MMN in the HA group and p‐MMR in the CI group (F(2,43) = 3.40, p = 0.043). The p‐MMR correlated negatively with age, with the strongest correlation in the NH subjects. In the CI group, the late discriminative negativity (LDN) was replaced by a late positivity with a significant group interaction for the location deviant. Children with severe HI can be assessed through their hearing device with a fast multi‐feature paradigm. For further studies a multi‐feature paradigm including more complex speech sounds may better capture variation in auditory processing in these children.     

Variations of the flanker paradigm: Assessing selective attention in young children

The development of selective attention and associated self-regulatory processes was assessed in young children, ages 4, 5, and 6, through the use of three alternative versions of the flanker paradigm utilizing colors, shapes, and fish. These variations were used to examine the influence of task differences on children’s performance. The presence of cognitive self-regulatory strategies in young children was also assessed. Significant flanker interference effects, marked by significant task-linked response time differences, were found across all three versions of the paradigm. Although a significant portion of children demonstrated self-regulatory abilities, not every participant demonstrated the specific strategies of self-monitoring and response control. Furthermore, these differences were evident across all age groups. The implications of these results are discussed within the theoretical context of task development, taking into consideration the need to modify computerized attention paradigms for use with young children in order to reliably measure cognitive constructs across children and adults.     

Multimodal interactions in typically and atypically developing children: natural versus artificial environments

This review addresses the central role played by multimodal interactions in neurocognitive development. We first analyzed our studies of multimodal verbal and nonverbal cognition and emotional interactions within neuronal, that is, natural environments in typically developing children. We then tried to relate them to the topic of creating artificial environments using mobile toy robots to neurorehabilitate severely autistic children. By doing so, both neural/natural and artificial environments are considered as the basis of neuronal organization and reorganization. The common thread underlying the thinking behind this approach revolves around the brain’s intrinsic properties: neuroplasticity and the fact that the brain is neurodynamic. In our approach, neural organization and reorganization using natural or artificial environments aspires to bring computational perspectives into cognitive developmental neuroscience.     

Associations between gross motor and communicative development in at-risk infants

Infants’ advances in locomotion relate to advances in communicative development. However, little is known about these relations in infants at risk for delays in these domains and whether they may extend to earlier achievements in gross motor development in infancy. We examined whether advances in sitting and prone locomotion are related to communicative development in infants who have an older sibling with autism spectrum disorder (ASD) and are at risk for motor and communication delays (heightened-risk; HR). We conducted a longitudinal study with 37 HR infants who did not receive an ASD diagnosis at 36 months. Infants were observed monthly between the ages of 5 and 14 months. We assessed gross motor development using the Alberta Infant Motor Scales (AIMS) and recorded ages of onset of verbal and nonverbal communicative behaviors. Results indicated increased presence of early gross motor delay from 5 to 10 months. In addition, there were positive relations between sitting and gesture and babble onset and between prone development and gesture onset. Thus, links between gross motor development and communication extend to at-risk development and provide a starting point for future research on potential cascading consequences of motor advances on communication development.     

Differences and similarities between children,mothers, and teachers as informants on disruptive child behavior

Prevalence rates of disruptive child behaviors, based on structured psychiatric interviews, are presented for samples of clinic-referred prepubertal boys at two sites to investigate differences and similarities among reports of the behaviors from children, parents, and teachers. Children reported significantly less hyperactive/inattentive and oppositional behaviors than either parents or teachers. In contrast, children did not differ from parents or teachers in their report on the prevalence of more serious conduct problems. These results were well replicated across two sites, despite the fact that there were significant differences between the sites in the level of hyperactive/inattentive child behaviors and conduct problems. The ranking of parents' and teachers' reported prevalence of specific child behavior problems in each of the three domains of disruptive behavior was strikingly similar. With one exception, the concordance between the prevalence ranking based on the children's reports was lower than that based on adults' reports, Children's reports on their own behavior did not predict various child handicaps 1 year later as well as did adults' reports. The results are discussed in relation to the usefulness of certain child behaviors in symptom lists for diagnostic purposes; the reliability of children's reports on their own behavior; and the possible reasons why prevalence rankings, as perceived by adults, are so similar.     

Exploring the similarities and differences between person-centred and psychodynamic therapy

Person-centred therapy is compared to the psychodynamic approach defined by Hans Strupp and Jeffrey Binder. Their broad-based time-limited version is chosen because it is a precise manual ofhow to practise that has been assembled from 30 years of research and practice experience. It is demonstrated that person-centred practice and theory are psychodynamic in a general psychoanalytic sense because they refer to unconscious processes. Furthermore, it is proposed that person-centred practice could be enriched by reconsidering the differences to and similarities with psychodynamic therapy, thereby establishing greater clarity about each form of practice and further defining the boundary between these similar forms of relationship and feeling-oriented work.     

A longitudinal study of gendered vocabulary and communicative action in young children

Development of children's vocabularies for gender-typed words and communicative actions was investigated longitudinally from 13 to 36 months and in a group of 9.5-month-olds. Vocabularies of gendered words were assessed using lists of adult-rated gender-typed words from the MacArthur-Bates Communicative Development Inventories (CDI; L. Fenson et al., 1994). At 24 to 36 months, girls' and boys' productive vocabularies contained more same-gender-typed words than other-gender-typed words. Receptive vocabulary gender-differential effects were apparent among boys at 18 months. At 13 and 18 months, gender-typed differences were apparent in communicative actions. The research reveals the utility of unobtrusive, nonexperimental measures for assessing gender-related knowledge and behavior in young children.     

Changing interactions between teachers and socially inhibited kindergarten children: An interpersonal approach

In a short-term longitudinal intervention study, it was investigated whether a short teacher training in interpersonal theory and the complementarity principle could be used to break negative interaction cycles between teachers and socially inhibited kindergartners. Sixty-five children and their 35 regular teachers were observed in a dyadic task setting, on three occasions. In the training, it was explained that teachers could elicit more initiative from children by being less dominant and more friendliness by being more affiliative. Independent observers rated teachers' and children's interactive behaviors in 5-second episodes. Teachers reported on children's social inhibition. Multilevel analyses showed that the training elicited a decrease in teacher control at follow-up. Unexpectedly, the training increased teachers' complementarity on the affiliation dimension, especially in interactions with highly inhibited children. Implications for theory and practice are discussed.     

Communicative development in Swedish children 16-28 months old: the Swedish early communicative development inventory--words and sentences

To describe the development of words and sentences in Swedish children 16-28 months old, 900 parental reports on 336 children were analyzed. Subjects were randomly selected from the national birth register, and there was a response rate of 88%. The assessments were made using the Swedish Early Communicative Development Inventory--words and sentences (SECDI--w&s). Age-based norms for productive vocabulary, pragmatic skills, grammar skills, and maximum length of utterance (MaxLU) were determined. We describe the development of feedback morphemes, semantic categories, and single words and tasks. Correlation across measures was significant, and especially strong between vocabulary size and grammar skills. Optimized positive predictive values were high for 25 to 28 month predictions (71%-88%), and vocabulary scores were found to be of particular predictive importance. No significant gender differences were detected. The clinical relevance of the instrument is discussed.     

A comparative study of the use of visual communicative signals in interactions between dogs (Canis familiaris) and humans and cats (Felis catus) and humans

Dogs' (Canis familiaris) and cats' (Felis catus) interspecific communicative behavior toward humans was investigated. In Experiment 1, the ability of dogs and cats to use human pointing gestures in an object-choice task was compared using 4 types of pointing cues differing in distance between the signaled object and the end of the fingertip and in visibility duration of the given signal. Using these gestures, both dogs and cats were able to find the hidden food; there was no significant difference in their performance. In Experiment 2, the hidden food was made inaccessible to the subjects to determine whether they could indicate the place of the hidden food to a naive owner. Cats lacked some components of attention-getting behavior compared with dogs. The results suggest that individual familiarization with pointing gestures ensures high-level performance in the presence of such gestures; however, species-specific differences could cause differences in signaling toward the human.
