A contradiction resolved: Children's processing of syntactic cues.

Using 6-9 yr old children, an attempt was made to replicate D. McNeill's (1970) investigation, which suggested that although semantic cues aided processing of sentences by 5-8 yr olds, syntactic cues did not. In agreement with other more recent studies, results show that children's ability to process syntactically well-formed sentences increased over the early school years. The difference between McNeill's data and later data sets probably stems from (a) unreliability owing to small samples (5 children) at each age level and (b) unreliability due to the high difficulty of sentences used for the criterion.

Personalized inferences of emotions and appraisals: Component processes and correlates.

Examined children's abilities to consider other people's personal history when inferring their cognitive appraisals and probable emotional reactions. Study 1 explored the sources of children's difficulty in making personalized inferences of emotion. Interviewed children averaging 6, 8, and 11 years of age about a series of stories describing a person's behavior or experience in one situation, followed by a second, related situation, or about partial stories. The youngest children had trouble figuring out mental appraisals from personal history information. Older children were capable of inferring appraisals but had trouble applying them to later situations when both steps were required to infer the person's emotion. Study 2 examined the extent to which social and cognitive factors are associated with the ability to make personalized inferences among 8-year-olds. The tendency to make personalized inferences of appraisals was more clearly associated with sociometric status than with cognitive capacity measures, suggesting that this may be an important element of children's social competence.

Relations between children's overestimation of their physical abilities and accident proneness.

Two experiments examined developmental changes in the accuracy of children's judgments about their physical abilities. Experiment 1 showed that 6- and 8-year-olds overestimated their ability to perform tasks just beyond and well beyond their ability. Adults only had difficulty making judgments about tasks just beyond their ability. Experiment 2 investigated how experience with performing activities influences judgments about physical abilities. Six-year-olds again overestimated their ability to perform tasks just beyond and well beyond their ability. Eight-year-olds were more accurate about tasks well beyond than just beyond their ability. In both experiments, overestimation of ability was associated with accidental injuries for 6- but not for 8-year-olds. The discussion focuses on children's overestimation of physical abilities and the relation between overestimation and accident proneness.

The Role of Conceptual Recoding in Reducing Children's Retroactive Interference.

Reductions in children's retroactive interference were examined with conceptual recoding. Children learned two 10-item lists of toys; items on the 2nd list could also be classified as vehicles. Some children were not told about this 2nd category, whereas others were told either at the end of acquisition or just prior to the retention test 24 hr later. The results showed that (a) children benefited from the recoding instruction, (b) younger but not older children failed to benefit from the recoding manipulation when it occurred just prior to the retention test, and (c) recoding reduced retroactive interference primarily through affecting storage processes. These results provide new evidence concerning the importance of making information distinctive in storage in children's retention. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Ethnic diversity and distributed information in group decision making: The importance of information elaboration.

Ethnic diversity may impede groups' use of distributed information in decision making. This is not so much because diversity interferes with groups' ability to reach agreement, but because ethnic diversity may disrupt the elaboration (exchange and integration) of distributed information. The authors find evidence for this proposition in an experiment (N = 63 groups) in which ethnically diverse groups are shown to benefit more from instructions emphasizing information integration than ethnically homogeneous groups when dealing with distributed information, whereas neither ethnic diversity nor information integration instruction affected decision making performance in groups with fully shared information. These effects were mediated by a behavioral measure of group information elaboration. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Multiple pathways to compliance: Mothers' willingness to cooperate and knowledge of their children's reactions to discipline.

Mothers of 59 children with ages from 6 to 9 years were assessed for their general willingness to cooperate with their children's desires and their accurate predictions of their children's evaluations of different discipline strategies. Mothers asked their children to clean up a playroom in their absence, with some children protesting and others not protesting. Results showed that maternal willing cooperation predicted children's compliance in the absence but not in the presence of protest. Conversely, maternal accuracy concerning their children's evaluations of discipline facilitated children's compliance in dyads in which children expressed initial resistance but not if children indicated no opposition. Mothers' responsive reactions to protest mediated between maternal accuracy and children's ultimate compliance. Results indicate that specific features of parenting facilitate compliance in specific situations. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Developmental differences in the use of distinctiveness, consensus, and consistency information for making causal attributions.

Examined developmental differences in the use of distinctiveness, consensus, and consistency information for making causal attributions. 144 1st, 3rd and 6th graders and college students were presented with brief story pairs consisting of an act manifested by an agent toward a target person. Each story in a pair was accompanied by a different level of a particular type of information (e.g., high consensus for one and low consensus for the other). Ss were asked to make causal inferences about both the agents and the targets. Results reveal significant age-related differences in the ability to use each type of information. Young children's use of distinctiveness information yielded the predicted agent attributions significantly more often than it yielded the predicted target attributions, while the reverse was true for consensus information. Findings are interpreted in terms of causal principles: Information was used in the predicted manner at a younger age when a covariation principle was required than when a discounting principle was required.

The changing composition of abstracted categories under manipulations of decisional change, choice difficulty, and category size.

The role of decisional factors in category abstraction was investigated. The major prediction was that a change in instructional set would primarily affect the more difficult choices of a category (boundary contraction hypothesis), with this outcome modulated by category size. Subjects classified patterns into three prototype categories until they reached an errorless criterion; then they immediately took a transfer test under a conservative or liberal set. Category size was varied independently of category frequency in Experiment 1; in Experiment 2, category size functioned as a between-subjects variable. The results showed that instructional set affected new, but not old, instances, with this effect additive across choice difficulty and category size. The boundary contraction hypothesis was rejected, and a two-stage model of classification was proposed to account for the results. A compositional analysis revealed that far greater levels of learning may be needed before selective decision making can occur. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The importance of knowing a dodo is a bird: Categories and inferences in 2-year-old children.

This study examined 2-year-old children's ability to make category-based inferences. Subjects were asked a series of questions that they could answer based on category membership, appearances, or both. In one condition, all pictures were named; in a second condition, none were named. Children performed well on prototypical pictures regardless of whether they were named; on atypical pictures, they performed better when category labels were provided. A control study demonstrated that children ignored the label when it named a transient property rather than a stable category. Contrary to standard views of young children, these results indicate an early-emerging capacity to overlook salient appearances. However, one important development still to take place is the ability to use subtle perceptual cues to determine category membership in the absence of language.

Sensitivity and teaching by dysphoric and nondysphoric women in structured versus unstructured situations.

This study compared the sensitivity and teaching strategies of dysphoric and nondysphoric women working with unfamiliar 5- and 6-year-olds. Interactions of 20 dysphoric and 20 nondysphoric mothers and an unfamiliar child were observed during 2 classification tasks and 3 unstructured activities staged as breaks. Nondysphoric women were more sensitive to children's level of understanding than dysphoric women and were more likely to use a variety of teaching strategies. Dyads with nondysphoric women were also more likely to share decision making than dyads with dysphoric women. These differences between dysphoric and nondysphoric women were significant only in the structured classification tasks. The findings indicate that in some situations dysphoric and nondysphoric women vary in their sensitivity to children's cues and in the teaching strategies they use with children.

Inference using categories.

How do people use category membership and similarity for making inductive inferences? The authors addressed this question by examining the impact of category labels and category features on inference and classification tasks that were designed to be comparable. In the inference task, participants predicted the value of a missing feature of an item given its category label and other feature values. In the classification task, participants predicted the category label of an item given its feature values. The results from 4 experiments suggest that category membership influences inference even when similarity information contradicts the category label. This tendency was stronger when the category label conveyed class inclusion information than when the label reflected a feature of the category. These findings suggest that category membership affects inference beyond similarity and that category labels and category features are 2 different things.

Influence of Virtual Reality Training on the Roadside Crossing Judgments of Child Pedestrians.

The roadside crossing judgments of children aged 7, 9, and 11 years were assessed relative to controls before and after training with a computer-simulated traffic environment. Trained children crossed more quickly, and their estimated crossing times became better aligned with actual crossing times. They crossed more promptly, missed fewer safe opportunities to cross, accepted smaller traffic gaps without increasing the number of risky crossings, and showed better conceptual understanding of the factors to be considered when making crossing judgments. All age groups improved to the same extent, and there was no deterioration when children were retested 8 months later. The results are discussed in relation to theoretical arguments concerning the extent to which children's pedestrian judgments are amenable to training.

Discrimination and identification of voicing and place contrasts in aphasic patients.

Examined the relationship between ability to discriminate and identify 3 synthetic speech continua representing vowel, voicing, and place contrasts and level of auditory language comprehension in 19 41–68 yr old male aphasics and 8 42–65 yr old non-brain-damaged controls. Aphasics were assigned to a good or a moderate comprehension group (GCG and MCG) on the basis of their auditory language comprehension scores. Both groups of aphasics performed the same as controls on the vowel contrasts. In comparison with controls, aphasics in the MCG had difficulty perceiving voicing and place contrasts, whereas aphasics in the GCG had difficulty perceiving place contrasts only. The MCG had more difficulty than the other 2 groups in discriminating stimuli at the inner boundary of each phoneme category. They were also most impaired in identifying the endpoints of the place and voicing continua. Place contrasts were more difficult to identify than voicing contrasts for both aphasic groups. In terms of the relationship between discrimination and identification, the majority of Ss either discriminated and identified the stimuli at equal levels of performance, or discriminated but did not identify the stimuli. Results indicate that auditory language comprehension predicts, to some extent, perception of voicing and place contrasts.

Estimation of employment test validities by expert judgment.

Compared the relative accuracy of 2 methods of estimating employment test validity: expert judgment and small sample criterion-related validation studies. The study was based on US Navy data from samples of over 3,000 for each of 9 jobs, with validity results on 6 tests for each job. 20 experienced psychologists estimated the observed validity for each of the 54 test–job combinations. Both the random and systematic error in the expert judgments were evaluated. Psychologists typically underestimated the validity by a small amount (an average systematic error of .019). On the average, to equal the accuracy of a single judge, the sample size of a criterion-related validation study would have to be 92. To match the accuracy of an average across 4 judges, the sample size must be 326. The sample size must be 1,164 to match the accuracy of the pooled judgment of 30 judges. Results indicate that, given highly trained and experienced judges, expert judgment may provide more accurate estimates of validity for cognitive tests than do local criterion-related validation studies.

The role of local and distal landmarks in the development of object location memory.

To locate objects in the environment, animals and humans use visual and nonvisual information. We were interested in children's ability to relocate an object on the basis of self-motion and local and distal color cues for orientation. Five- to 9-year-old children were tested on an object location memory task in which, between presentation and test, the availability of local and distal cues was manipulated. Additionally, participants' viewpoint could be changed. We used a Bayesian model selection approach to compare our hypotheses. We found that, to remain oriented in space, 5-year-olds benefit from visual information in general, 7-year-olds benefit from visual cues when a viewpoint change takes place, and 9-year-olds do not benefit from the availability of visual cues for orientation but rely on self-movement cues instead. Results are discussed in terms of the adaptive combination model (Newcombe & Huttenlocher, 2006). (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

The learning of exclusive-or categories by monkeys (Macaca mulatta) and humans (Homo sapiens).

A central question in categorization research concerns the categories that animals and humans learn naturally and well. Here, the authors examined monkeys' (Macaca mulatta) and humans' (Homo sapiens) learning of the important class of exclusive-or (XOR) categories. Both species exhibited—through a sustained level of ongoing errors—substantial difficulty learning XOR category tasks at 3 stimulus dimensionalities. Clearly, both species brought a linear-separability constraint to XOR category learning. This constraint illuminates the primate category-learning system from which that of humans arose, and it has theoretical implications concerning the evolution of cognitive systems for categorization. The present data also clarify the role of exemplar-specific processes in fully explaining XOR category learning, and suggest that humans sometimes overcome their linear-separability constraint through the use of language and verbalization.

Children's Reading Comprehension Ability: Concurrent Prediction by Working Memory, Verbal Ability, and Component Skills.

The authors report data from a longitudinal study that addresses the relations between working memory capacity and reading comprehension skills in children aged 8, 9, and 11 years. At each time point, the authors assessed children's reading ability, vocabulary and verbal skills, performance on 2 working memory assessments (sentence-span and digit working memory), and component skills of comprehension. At each time point, working memory and component skills of comprehension (inference making, comprehension monitoring, story structure knowledge) predicted unique variance in reading comprehension after word reading ability and vocabulary and verbal ability controls. Further analyses revealed that the relations between reading comprehension and both inference making and comprehension monitoring were not wholly mediated by working memory. Rather, these component skills explained their own unique variance in reading comprehension. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
