Children's attributions of intentions to an invisible agent.

Children ages 3-9 years were informed that an invisible agent (Princess Alice) would help them play a forced-choice game by "telling them, somehow, when they chose the wrong box," whereas a matched control group of children were not given this supernatural prime. On 2 unexpected event trials, an experimenter triggered a simulated unexpected event (i.e., a light turning on/off; a picture falling), and children's behavioral response to these events (i.e., moving their hand to the opposite box) was coded. Results showed a significant Age Group × Experimental Condition interaction; the only children to reliably alter their behavior in response to the unexpected events were the oldest children (M = 7 years 4 months), who were primed with the invisible agent concept. For children's posttest verbal explanations, also, only these children saw the unexpected events as being referential and declarative (e.g., "Princess Alice did it because I chose the wrong box"). Together, these data suggest that children may not regularly begin to see communicative signs as embedded in unexpected events until they are around 7 years of age.

Writing and revising persuasive documents: Cognitive demands.

In 2 experiments, 40 graduate and 60 undergraduate students wrote preliminary and final drafts of a persuasive document. In Exp I, the need for Ss to comply with mechanics (i.e., punctuation and spelling), to form complete sentences, and to sequence their ideas, respectively, were eliminated one at a time from preliminary-draft formats. The elimination of sentence-formation and sequence operations produced corresponding increments in persuasive argument production. In Exp II, Ss with average verbal ability (as assessed by the Scholastic Aptitude Test) benefited more from the elimination of these structure operations than did Ss with low verbal ability. When allowed to freely choose their typical preliminary-draft format, Ss with average verbal ability usually selected proposition-based formats (e.g., lists, outlines, and diagrams) that dispensed with the need for structure operations. Ss with average verbal ability also produced more sentences, more arguments per sentence, and fewer mechanical errors than did those with low verbal ability. In both experiments, comparatively few new arguments were constructed during revision. (21 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Learning mathematics from procedural instruction: Externally imposed goals influence what is learned.

Do externally imposed achievement goals influence what children learn from procedural instruction? Third- and 4th-grade children's goals were manipulated toward either learning or performance. All children were then taught a procedure for solving mathematical equivalence problems (e.g., a?+?b?+?c?=?a?+?_). Children who were given learning goals were initially more likely to gain conceptual knowledge from the procedural lesson than were children who were given performance goals. After a 2-week period, however, children who were given performance goals exhibited the same conceptual gains as children who were given learning goals. Both initially and after the 2-week period, children who were given either goal were more likely to extend their knowledge beyond the taught procedure than were children who were not given goals. External sources such as teachers and parents may have the potential to foster children's learning by shaping children's goals. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Making children gesture brings out implicit knowledge and leads to learning.

Speakers routinely gesture with their hands when they talk, and those gestures often convey information not found anywhere in their speech. This information is typically not consciously accessible, yet it provides an early sign that the speaker is ready to learn a particular task (S. Goldin-Meadow, 2003). In this sense, the unwitting gestures that speakers produce reveal their implicit knowledge. But what if a learner was forced to gesture? Would those elicited gestures also reveal implicit knowledge and, in so doing, enhance learning? To address these questions, the authors told children to gesture while explaining their solutions to novel math problems and examined the effect of this manipulation on the expression of implicit knowledge in gesture and on learning. The authors found that, when told to gesture, children who were unable to solve the math problems often added new and correct problem-solving strategies, expressed only in gesture, to their repertoires. The authors also found that when these children were given instruction on the math problems later, they were more likely to succeed on the problems than children told not to gesture. Telling children to gesture thus encourages them to convey previously unexpressed, implicit ideas, which, in turn, makes them receptive to instruction that leads to learning.

A neuropsychological study of fact memory and source amnesia.

We investigated the ability of amnesic patients to learn new facts (e.g., Angel Falls is located in Venezuela) and also to remember where and when the facts were learned (i.e., source memory). To assess the susceptibility of fact and source memory to retrograde amnesia, patients prescribed electroconvulsive therapy were presented facts prior to the first treatment and were tested after their second treatment. All amnesic patients exhibited marked fact memory impairment. In addition, some amnesic patients exhibited source amnesia (i.e., they recalled a few facts but then could not remember where or when those facts had been learned). Source amnesia was unrelated to the severity of the memory deficit itself, because patients who exhibited source amnesia recalled as many facts as the patients who did not. These results show that the deficit in amnesia includes an impairment in acquiring and retaining new facts. Source amnesia can also occur, but it is dissociable from impaired recall and recognition and appears to reflect difficulty in remembering the specific context in which information is acquired. The findings are discussed in terms of their significance for how memory is organized. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The relation between individual differences in fantasy and theory of mind

The relation between early fantasy/pretense and children's knowledge about mental life was examined in a study of 152 3- and 4-year-old boys and girls. Children were interviewed about their fantasy lives (e.g., imaginary companions, impersonation of imagined characters) and were given tasks assessing their level of pretend play and verbal intelligence. In a second session 1 week later, children were given a series of theory of mind tasks, including measures of appearance-reality, false belief, representational change, and perspective taking. The theory of mind tasks were significantly intercorrelated with the effects of verbal intelligence and age statistically controlled. Individual differences in fantasy/pretense were assessed by (1) identifying children who created imaginary characters, and (2) extracting factor scores from a combination of interview and behavioral measures. Each of these fantasy assessments was significantly related to the theory of mind performance of the 4-year-old children, independent of verbal intelligence.     

Chess: A psychoanalytic tool in the treatment of children.

Proposes a theoretical rationale for the clinical application of chess instruction to the psychoanalytic process in working with inner city children and adolescents who may present particular resistance to the focus on verbal communication in traditional therapy. The chess pieces are seen as embodying parental symbols and the competition of the game is seen as symbolizing Oedipal issues. Transference phenomena in the relationships of students to the instructor are discussed and learning effective strategies of play is related to developing impulse control. A case study is described of an aggressive male pre-adolescent special education student who benefited from this intervention. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Moving beyond efficacy and effectiveness in child and adolescent intervention research.

This Special Section of the Journal of Consulting and Clinical Psychology focuses on research that extends beyond documenting the efficacy and effectiveness of specific psychological treatments or preventive interventions for children and youths. In the past 30 years, there have been remarkable advances in the development and evaluation of psychological treatments and preventive interventions for a wide range of child and adolescent problems. At the same time, only a small percentage of youths who suffer from emotional and behavioral problems receive psychological services, and many of these services are not evidence-based. This article discusses key features of the Special Section studies, which examine important issues related to (a) disseminating treatments in diverse community settings (i.e., investigating the transportability of treatment), (b) personalizing mental health care (i.e., investigating predictors and moderators of treatment outcome), and (c) developing evidence-based explanations of treatment (i.e., investigating mediators of treatment). Key issues that are raised in the specific studies are discussed, and important considerations for future research are highlighted. Moving the field forward requires innovation, complex research designs, and a willingness to develop treatment models that reach beyond the current body of treatment outcome and prevention research.

An exploratory analysis of American Indian children's cultural engagement, fluid cognitive skills, and standardized verbal IQ scores.

This exploratory cross-sectional study examined fluid cognitive skills and standardized verbal IQ scores in relation to cultural engagement amongst Tohono O'odham children (N = 99; ages 7 to 12 years). Guardians with higher socioeconomic status engaged their children in more cultural activities, and participation in more cultural activities contributed to higher standardized verbal IQ scores. Mean cognitive skill scores varied as a function of age and Tohono O'odham language knowledge. Children who understood and/or spoke Tohono O'odham started out with lower average scores than did children with no language knowledge, but mean scores generally increased in the older age groups such that they were equal to or higher than those of nonspeakers by age 9. Children with higher fluid cognitive skill scores had higher standardized verbal IQ scores than did children with lower scores. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Early Development of Neurophysiological Processes Involved in Normal Reading and Reading Disability: A Magnetic Source Imaging Study.

This longitudinal study examined the development of the brain mechanism involved in phonological decoding in beginning readers using magnetic source imaging. Kindergarten students were assigned to 2 groups: those who showed mastery of skills that are important predictors of proficient reading (low-risk group) and those who initially did not show mastery but later benefited from systematic reading instruction and developed average-range reading skills at the end of Grade 1 (high-risk responders). Spatiotemporal profiles of brain activity were obtained during performance of letter-sound and pseudoword naming tasks before and after Grade 1 instruction. With few exceptions, low-risk children showed early development of brain activation profiles that are typical of older skilled readers. Provided that temporoparietal and visual association areas were recruited into the brain mechanism that supported reading, the majority of high-risk responder children benefited from systematic reading instruction and developed adequate reading abilities.

The impact of monetary reward on memory in schizophrenia spectrum disorder.

The impact of monetary reward on verbal working memory (vWM) and verbal long-term memory (vLTM) was evaluated in 50 patients with schizophrenia spectrum disorders and 52 matched healthy participants. This research was motivated by the observations that negative symptoms in schizophrenia are associated with reduced drive and that patients with these symptoms exhibit greater mnemonic impairments. Reward-related gains were evaluated across two levels of vWM load on the n-back task and across three aspects of vLTM derived from the California Verbal Learning Test-II (i.e., learning, total immediate recall, and retention). Although healthy individuals benefited from reward at a high vWM load level, schizophrenia patients exhibited no reward-related improvements in vWM. In contrast, improvement in vLTM retention was induced by reward for both patients and controls. Finally, symptomatic and pharmacology treatment factors were associated with reward-related gains in persons with schizophrenia. In conclusion, contingent monetary rewards delivered during vWM and vLTM enhanced specific aspects of memory. The influence was relatively small and dependent on the specific neurocognitive operation examined, the mental health status of the participants, and for patients, their particular symptoms and pharmacological treatments.

Lexical acquisition in elementary science classes.

The purpose of this study was to further researchers' understanding of lexical acquisition in the beginning primary schoolchild by investigating word learning in small-group elementary science classes. Two experiments were conducted to examine the role of semantic scaffolding (e.g., use of synonymous terms) and physical scaffolding (e.g., pointing to referents) in children's acquisition of novel property terms. Children's lexical knowledge was assessed using multiple tasks (naming, comprehension, and definitional). Children struggled to acquire meanings of adjectives without semantic or physical scaffolding (Experiment 1), but they were successful in acquiring extensive lexical knowledge when offered semantic scaffolding (Experiment 2). Experiment 2 also shows that semantic scaffolding used in combination with physical scaffolding helped children acquire novel adjectives and that children who correctly named pictures of adjectives had acquired definitions.

This cat has nine lives? Children's memory for genericity in language.

Generic noun phrases ("Birds lay eggs") are important for expressing knowledge about abstract kinds. The authors hypothesized that genericity would be part of gist memory, such that young children would appropriately recall whether sentences were presented as generic or specific. In 4 experiments, preschoolers and college students (N = 280) heard a series of sentences in either generic form (e.g., "Bears climb trees") or specific form (e.g., "This bear climbs trees") and were asked to recall the sentences following a 4-min distractor task. Participants in all age groups correctly distinguished between generic and specific noun phrases (NPs) in their recall, even when forgetting the details of the NP form. Memory for predicate content (e.g., "climb trees") was largely unaffected by genericity, although memory for category labels (e.g., "bear") was at times better for those who heard sentences with generic wording. Overall, these results suggest that generic form is maintained in long-term memory even for young children and thus may serve as the foundation for constructing knowledge about kinds.

She’s emotional. He’s having a bad day: Attributional explanations for emotion stereotypes.

People believe that women are the more emotional sex. This belief stems less from what men and women actually do than from the explanations given for their behaviors. In 2 studies, participants who were given situational information about the causes of emotional expression in target faces nonetheless more frequently judged feminine targets depicting emotions as “emotional” (i.e., a dispositional attribution for the emotional behavior), whereas they more frequently judged masculine targets as “having a bad day” (i.e., a situational attribution for the emotional behavior). These findings help explain the pervasive belief that women are more emotional when compared with men, even when the scientific veracity of this belief is questionable.

Individual differences in 4-year-old children's acquisition of vocabulary during storybook reading.

Two experiments were conducted to assess how children who differ in vocabulary knowledge learn new vocabulary incidentally from listening to stories read aloud. In both experiments, 4-yr-old children were classified as having either high or low word knowledge on the basis of a median split of their Peabody Picture Vocabulary Test—Revised (PPVT—R) standard scores. In Exp 1, children either listened passively or labeled pictures using novel words during the book readings. We found that children with larger vocabularies produced more novel words than did children with smaller vocabularies, and children who answered questions during the book readings comprehended and produced more words than did children who passively listened to the story. In Exp 2, children either listened to readings of a book, pointed to pictures during the readings, or labeled pictures during the readings. Children with larger vocabularies comprehended more novel words than did children with smaller vocabularies. Children who actively participated by labeling or pointing learned more words than did children who listened passively to book readings. Findings clarify the role of active responding by demonstrating that verbal and nonverbal responding are effective means of enhancing vocabulary acquisition.

The effects of response instructions on situational judgment test performance and validity in a high-stakes context.

This study fills a key gap in research on response instructions in situational judgment tests (SJTs). The authors examined whether the assumptions behind the differential effects of knowledge and behavioral tendency SJT response instructions hold in a large-scale high-stakes selection context (i.e., admission to medical college). Candidates (N = 2,184) were randomly assigned to a knowledge or behavioral tendency response instruction SJT, while SJT content was kept constant. Contrary to prior research in low-stakes settings, no meaningfully important differences were found between mean scores for the response instruction sets. Consistent with prior research, the SJT with knowledge instructions correlated more highly with cognitive ability than did the SJT with behavioral tendency instructions. Finally, no difference was found between the criterion-related validity of the SJTs under the two response instruction sets. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Implant cochléaire et développement des échanges conversationnels.

Most researches conducted in the field of postimplant assessment have focused on the restoration of perceptual capabilities and the development of verbal language. In contrast, only very few studies have examined the impact of a cochlear implantation on children's overall development and, in particular, on their conversational language abilities. However, some previous works on the preverbal development revealed the recurrent difficulties experienced by deaf children in acquiring knowledge of social rules and social skills relative to speech activities. In children with profound bilateral deafness, a conventional hearing aid is not enough to provide sufficiently relevant information for a satisfactory development of oral communication. In such situations, the most suitable way of improving hearing is the use of a cochlear implant. The authors therefore hypothesized that access to oral perception will not only improve implanted children's social skills, but will also increase their rate of participation and the use of verbal language in their interaction with a familiar adult (mother or father). Their communication skills profile would resemble that of younger normal hearing children. Using conversational samples from a video-filming protocol at specific intervals, the authors monitored the development of communication skills in a group of 20 prelingually, profoundly deaf children (mean age: 3.7 years). Results corroborated our hypothesis. They indicated that children using cochlear implants increased their overall performance in communication skills, quantitatively and qualitatively speaking, even at the first year postimplantation stage.

An examination of the nature and correlates of ethnic harassment experiences in multiple contexts.

The authors examined the nature and correlates of ethnic harassment experiences in 4 predominantly Hispanic samples of working men and women (N?=?575) using a newly developed scale. Confirmatory factor analyses supported a 2-factor structure for the Ethnic Harassment Experiences scale (i.e., verbal ethnic harassment and exclusion due to ethnicity). Most experiences of ethnic harassment in the workplace during the previous 24 months included verbal ethnic harassment (i.e., ethnic slurs, derogatory ethnic comments, or ethnic jokes). It was also found that participants who experienced verbal ethnic harassment and exclusion reported negative correlates that could not be attributed to affective disposition. For some correlates, those who experienced low levels of verbal harassment and high levels of exclusion were more negatively affected than others, perhaps as a result of the attributional ambiguity of the situation.

Valence Focus and the Perception of Facial Affect.

Individuals differ in the extent to which they emphasize feelings of pleasure or displeasure in their verbal reports of emotional experience, an individual difference termed valence focus (VF). This multimethod study indicates that VF is linked to heightened efficiency in perceptual processing of affective stimuli. Individuals higher in VF (i.e., who emphasized feelings of pleasure/displeasure in reports of emotional experiences) were more sensitive to changes in negative facial expressions than individuals lower in VF. The effect was not accounted for by current affective state or other personality characteristics. Implications for the validity of self-reported experienced emotion are discussed.
