A sequential analysis of private and social speech in children's dyadic communication

The purpose of this study was to perform a sequential analysis of private and social speech in children's dyadic communication. To investigate the communication patterns, a category system was applied to the communication of 64 paired third (M = 8 years and 8 months) and fifth (M = 10 years and 8 months) graders, while playing with a Lego-set (construction material). The results revealed that: (a) at both grades, when one child addresses the other child about the task, it is highly probable that the latter will address the first child immediately afterwards and will adapt to task-related semantic content; (b) at both grades, children's private speech about the task stops them from communicating a task-related production to their partner immediately afterwards; (c) at third grade, task-relevant private speech favors the prolongation of the break in interpersonal communication and the use of inner speech by both children; and (d) at fifth grade, children are more able to distinguish private speech from social speech than at third grade.     

Accurate referential communication and its relation with private and social speech in a naturalistic context

Research into human communication has been grouped under two traditions: referential and sociolinguistic. The study of a communication behavior simultaneously from both paradigms appears to be absent. Basically, this paper analyzes the use of private and social speech, through both a referential task (Word Pairs) and a naturalistic dyadic setting (Lego-set) administered to a sample of 64 children from grades 3 and 5. All children, of 8 and 10 years of age, used speech that was not adapted to the decoder, and thus ineffective for interpersonal communication, in both referential and sociolinguistic communication. Pairs of high-skill referential encoders used significantly more task-relevant social speech, that is, cognitively more complex, than did low-skill dyads in the naturalistic context. High-skill referential encoder dyads showed a trend to produce more inaudible private speech than did low-skill ones during spontaneous communication. Gender did not affect the results.     

Private and social speech in communication: Terminology and distinctive traits

The study of private and social speech demands a considerable initial effort from beginning scientists to clarify the terms and concepts related to the phenomenon. The present article looks at the different labels used and at their conceptual definitions, distinguishing two stages: the origin of the conceptual debate by Piaget and Vygotsky (which has been sometimes misunderstood),and the later contributions by other authors. The above contributions led to the current terms (private speechand social speech)that have finally prevailed. In this article the use of these latter terms is justified and two new subterms, which increase their accuracy, are coined: social speech of private meaningand social speech of public meaning.This study is from a section of a larger project, which was funded by two grants from the Institut de Sociolingüística Catalana (Direcció General de Política Lingüística—Generalitat de Catalunya), in 1992 and 1993, and one grant from the Divisió de Ciències de la Salut (University of Barcelona). It was carried out as part of the requirements for the author's Ph.D., whose unconditional advisor was H. Boada. I also thank J. C. Oliver for reviewing the English writing.     

Implicit semantic priming in Spanish-speaking children and adults: an auditory lexical decision task

Although receptive priming has long been used as a way to examine lexical access in adults, few studies have applied this method to children and rarely in an auditory modality. We compared auditory associative priming in children and adults. A testing battery and a Lexical Decision (LD) task was administered to 42 adults and 27 children (8;1-10; 11 years-old) from Spain. They listened to Spanish word pairs (semantically related/unrelated word pairs and word-pseudoword pairs), and tone pairs. Then participants pressed one key for word pairs, and another for pairs with a word and a pseudoword. They also had to press the two keys alternatively for tone pairs as a basic auditory control. Both groups of participants, children and adults, exhibited semantic priming, with significantly faster Reaction Times (RTs) to semantically related word pairs than to unrelated pairs and to the two word-pseudoword sets. The priming effect was twice as large in the adults compared to children, and the children (not the adults) were significantly slower in their response to word-pseudoword pairs than to the unrelated word pairs. Moreover, accuracy was somewhat higher in adults than children for each word pair type, but especially in the word-pseudoword pairs. As expected, children were significantly slower than adults in the RTs for all stimulus types, and their RTs decreased significantly from 8 to 10 years of age and they also decreased in relation to some of their language abilities development (e.g., relative clauses comprehension). In both age groups, the Reaction Time average for tone pairs was lower than for speech pairs, but only all adults obtained 100% accuracy (which was slightly lower in children). Auditory processing and semantic networks are still developing in 8-10 year old children.     

Effects of working memory load on long-term word priming

Three experiments assessed the role of verbal and visuo-spatial working memory in supporting long-term repetition priming for written words. In Experiment 1, two priming tasks (word stem completion and category-exemplar production) were included with three levels of load on working memory: (1) without memory load, (2) memory load that involved storing a string of six digits, and (3) memory load that involved storing a graphic shape. Experiments 2 and 3 compared the effects of a verbal (Experiment 2) or a visual (Experiment 3) working memory load at encoding on both an implicit (word stem completion) and an explicit test (cued recall). The results show no effect of memory load in any of the implicit memory tests, suggesting that priming does not rely on working memory resources. By contrast, loading working memory at encoding causes a significant disruptive effect on the explicit memory test for words when the load is verbal but not visual.     

Infant’s gaze in a teasing task with an experimenter or parent: A naturalistic approach

We assessed infant’s gaze in a teasing task in New York City public spaces. The task was administered to two different groups of 5- to 13-month-old infants. We used a between participants design across two studies. In Study 1 an experimenter administered the task to these infants (n = 79), whereas a parent did so in Study 2 (n = 79). The adult engaged the infant with a toy and then pulled it away to one side by counting to 7. A second trial to the other side was repeated. Infants passed the teasing task if they looked to the adult’s face within the first 5 seconds after removing the toy in at least one trial. In Study 1, we found that infants looked to the experimenter’s face after teasing by 7 months of age. In Study 2, infants did not show any significant gazes to the parent’s face after teasing at any age. Most trained parents successfully administered the teasing task to their infant. A teasing game played by an adult stranger (e.g., experimenter) may be optimal to elicit infant’s gaze in a naturalistic setting. Implications for developing cost-effective social-cognitive milestone measures in non-laboratory settings are discussed.     

Parent and teacher ratings of temperamental disposition to social anxiety: the BIS 3-6

Behavioral inhibition (BI) discourages children from interacting, predisposing them to isolation, social anxiety, and depression. We have created the Behavioral Inhibition Scale for Children Aged 3 to 6 (BIS 3-6) to detect this trait early. Parents and teachers of 365 preschoolers completed different versions of the BIS 3-6 and provided measures of psychopathology. Both versions are structured into 1 factor that explains over 40% of total variability and displays excellent internal consistency (α = .95). The moderate correlations with measures of internalizing symptoms (r = .50) and nonexistent correlations with externalizing measures suggest adequate convergent and discriminant validity. A new scoring system is proposed.     

Reliability and Validity of a Brief Clinician-Report Scale for Screening Behavioral Inhibition

Given the implications of behavioral inhibition (BI) on social anxiety and depression, several cost-effective methods have been developed to detect this trait. However, there is no instrument for obtaining a systematic measurement of BI that uses the reports of mental health professionals. The present study aims to explore the psychometric properties of the Behavioral Inhibition Observation System (BIOS), a brief tool enabling clinicians to provide a quick measure of BI. Parents and teachers of 361 preschool children provided measures of BI and psychopathology. Clinicians completed the BIOS after an individual meeting with every child. Seventy-four randomly selected children were exposed to standardized observation. Two researchers completed the BIOS after standardized observation. The results show that the BIOS is structured in one dimension that explains 60 % of the total variance. It shows good internal consistency (Cronbach’s Alpha?=?.88) and good test-retest reliability. The BIOS scores moderately converge with observational measures of BI and adequately distinguish constructs not related to BI (such as aggressiveness, disruptive behavior, or peer conflict). The results support that the BIOS, an 8-item scale that takes 3 min to complete, is valid and reliable for capturing a clinician’s measure of BI. The BIOS may help to detect temperamental disposition to social anxiety.     

Effects of working memory load on long‐term word priming

Three experiments assessed the role of verbal and visuo‐spatial working memory in supporting long‐term repetition priming for written words. In Experiment 1, two priming tasks (word stem completion and category‐exemplar production) were included with three levels of load on working memory: (1) without memory load, (2) memory load that involved storing a string of six digits, and (3) memory load that involved storing a graphic shape. Experiments 2 and 3 compared the effects of a verbal (Experiment 2) or a visual (Experiment 3) working memory load at encoding on both an implicit (word stem completion) and an explicit test (cued recall). The results show no effect of memory load in any of the implicit memory tests, suggesting that priming does not rely on working memory resources. By contrast, loading working memory at encoding causes a significant disruptive effect on the explicit memory test for words when the load is verbal but not visual.
