Orthographic complexity and word naming in Italian: Some words are more transparent than others

Italian is a language with a transparent orthography in which printed words can be translated into the correct sequence of phonemes using a limited set of rules. The rules of letter—sound conversion are, however, simpler for some letters than for others: The pronunciations of sequences involving the lettersc andg are determined by complex (i.e., context-sensitive) rules that depend on the letters that follow them. In this article, we report two experiments in which Italian participants read aloud words containing simple or complex letter—sound conversion rules. In Experiment 1, we found that words containing complex rules were read more slowly than words containing simple, noncontextual rules. In Experiment 2, we found that the effect of rule complexity on naming speed held for low-frequency words but not high-frequency words. The results are interpreted in terms of a dual-route model in which rule complexity effects arise from sublexical procedures that are more involved in reading low-frequency words than high-frequency words.

Some animal specific fears are more specific than others: Evidence from attention and emotion measures

Using a visual search methodology we investigated the effect of feared animal stimuli on attention. Our results confirmed the important role of emotion on attention. All participants detected fear-relevant stimuli (snakes and spiders) faster than neutral (mushrooms) ones against a background of fruits. In addition, spider fearful participants were sensitized specifically to detect their feared stimulus (spiders), compared to their fear-relevant but non-feared (snakes) and neutral stimuli. However, for participants fearful of snakes there was no significant difference in detection latencies between the feared (snakes) and the fear-relevant but non-feared animal stimuli (spiders). The results from the attention task were mirrored in the emotional ratings, which showed that spider fear was highly specific, whereas snake fear was associated with a more generalized enhanced evaluation of all negative stimuli.     

Some subordinates are more equal than others: Play fihgting amongst adult subordinate male rats

Adult male rats living together form dominance relationships, with one dominant and the remainder adopting subordinate roles. In previous studies, it was shown that in adult male pairs, the subordinate rat initiates more playful contacts and retains a more juvenile response to the playful contacts by the dominant. In this experiment, triads were used to examine the play between subordinate males. The subordinates directed fewer playful contacts to each other than to the dominant rat, and there was a symmetrical play relationship between the subordinates. After the dominant was removed from the colony, one subordinate became the dominant. Playful interactions amongst these pairs increased, with the subordiante intiating more playful contacts than the dominant. Furthermore, from a similarly low frequency of juvenile-type response to playful contact to each other when in triads, the subordinate in the dyads increased its frequency of juvenile responses to the dominant partner. This supports the hypothesis that the playful behavior of subordinate male rats towards the dominant is an adaptive response, playful behavior of subordinate male rats towards the dominant is an adaptive response, serving a “friendship maintenance” function. Finally, when in triads, one subordinate was more playful with the dominant than the other subordinate. It was the least playful subordinate that was the most likely to become the dominant. This sugests that within a colony, not all subordinates are the same. © 1993 Wiley-Liss, Inc.     

Preschool children's mathematical knowledge: The effect of teacher "math talk."

This study examined the relation between the amount of mathematical input in the speech of preschool or day-care teachers and the growth of children's conventional mathematical knowledge over the school year. Three main findings emerged. First, there were marked individual differences in children's conventional mathematical knowledge by 4 years of age that were associated with socioeconomic status. Second, there were dramatic differences in the amount of math-related talk teachers provided. Third, and most important, the amount of teachers' math-related talk was significantly related to the growth of preschoolers' conventional mathematical knowledge over the school year but was unrelated to their math knowledge at the start of the school year.     

Cross‐sectional and longitudinal relations between mother‐child talk about conflict and children's social understanding

We examined the relations between the ways 48 mothers and their 3‐ to 5‐year‐olds talked about a conflict depicted in a picture book and their children's current and subsequent level of social understanding. We distinguished explanatory talk, which directed attention to the actions that generated the conflict, from non‐explanatory talk, which discussed the conflict in terms of, for example, making up or saying sorry. Controlling for child age and overall talk by mother, explanatory talk was positively associated with contemporaneous social understanding. Social understanding at time one was also positively associated with social understanding 30 months later. These data suggest that dialogue about conflict may be helpful for 3‐ to 5‐year old children's understanding of the mental world, to the extent that it facilitates their understanding of particular social situations.     

Interparental conflict, negative parenting, and children's adjustment: bridging links between parents' depression and children's psychological distress

Pathways linking parental depressive symptoms, adult relationship insecurity, interparental conflict, negative parenting, and children's psychological adjustment (internalizing symptoms and externalizing problems) were assessed using a 3-wave longitudinal research design. Two-parent families (N = 352) with 11- to 13-year-old children (179 boys, 173 girls) participated in the study. Maternal and paternal depressive symptoms were associated with insecurity in adult close relationships assessed 12 months later, which was concurrently related to heightened levels of interparental conflict. Controlling for children's initial symptom levels, interparental conflict was related to child appraisals of father and mother rejection assessed an additional 12 months later, which were related to children's internalizing symptoms and externalizing problems, respectively. Results are discussed with regard to the implications for understanding the complex interplay between adult depressive symptoms, attributions in close adult relationships, interparental conflict, negative parenting, and children's psychological adjustment.     

Find the picture of eight turtles: a link between children's counting and their knowledge of number word semantics

An essential part of understanding number words (e.g., eight) is understanding that all number words refer to the dimension of experience we call numerosity. Knowledge of this general principle may be separable from knowledge of individual number word meanings. That is, children may learn the meanings of at least a few individual number words before realizing that all number words refer to numerosity. Alternatively, knowledge of this general principle may form relatively early and proceed to guide and constrain the acquisition of individual number word meanings. The current article describes two experiments in which 116 children (2½- to 4-year-olds) were given a Word Extension task as well as a standard Give-N task. Results show that only children who understood the cardinality principle of counting successfully extended number words from one set to another based on numerosity—with evidence that a developing understanding of this concept emerges as children approach the cardinality principle induction. These findings support the view that children do not use a broad understanding of number words to initially connect number words to numerosity but rather make this connection around the time that they figure out the cardinality principle of counting.     

Longitudinal associations between adolescent alcohol use and parents' sources of knowledge

The aim of this study was to test the direction of effect in the relationship between parents' sources of knowledge (parental monitoring and child disclosure) and adolescent alcohol use. The participants were 215 adolescents and their mothers, randomly selected from urban and rural areas in Cyprus. A 3‐month, two‐timepoint longitudinal design was used in which adolescents completed the alcohol use disorders identification test while mothers completed a parental knowledge questionnaire. The results of this study showed that parental monitoring did not predict subsequent adolescent alcohol use. However, child disclosure at Time 1 negatively predicted adolescent alcohol use at Time 2. Moreover, adolescents' alcohol dependence symptoms at Time 1 negatively predicted both sources of parental knowledge at Time 2.     

Young children's (Homo sapiens) understanding of knowledge formation in themselves and others.

Three- and 4-year-old children (Homo sapiens) were tested for comprehension of knowledge formation. In Experiment 1, 34 subjects watched as a surprise was hidden under 1 of 4 obscured cups. The experimenter then pointed to the cup. All children searched under the correct cup, but no 3-year-olds (in contrast to most 4-year-olds) could explain how they knew where to look. Subjects then discriminated between simultaneous pointing by 2 adults, one who had hidden a surprise and one who had left the room before the surprise was hidden. Most 4-year-olds (but no 3-year-olds) showed clear discrimination between the adults. In Experiment 2, 16 subjects were tested with procedures designed to make the source of their own knowledge more obvious, but this had no effect on performance. We conclude that studies using very similar procedures with chimpanzees and rhesus macaques were measuring an ability (or inability) to understand how knowledge states form.     

Why some are perceived as more confident and more insecure, more reckless and more cautious, more trusting and more suspicious, than others: Enriched and impoverished options in social judgment

In line with the principle of compatibility, when making social judgments, people tend to focus on personality attributes compatible with the trait under consideration. Better known, orenriched, personages are more likely to present attributes that are compatible with a particular trait than are personages about whom little is known. As a result, enriched personages are more likely to have various, sometimes even conflicting, traits attributed to them. This hypothesis is supported by a number of studies that compare the frequency with which some people are chosen as being better described by opposite trait adjectives than are others. Celebrities more often have both of a pair of opposing adjectives ascribed to them than do less well known figures. Similarly, subjects judge themselves to be better described by either of a pair of opposite adjectives than is a person who is relatively unknown in their lives. The implications for social judgment and for everyday decisions are discussed.     

More than talk: Relations between emotion understanding and positive behaviour in toddlers

Background. Associations between positive behaviour, emotion understanding and verbal ability have been reported in studies of preschoolers ( Cassidy, Werner, Rourke, Zubernis, & Balaraman, 2003 ), but have yet to be investigated in younger children. Methods. In this study the performance of 36 toddlers (17 boys and 19 girls; mean age = 29 months, SD = 3.9 months) on standardized verbal ability assessments and four simple tests of emotion understanding was examined in relation to three measures of positive behaviour: maternal ratings of prosocial behaviour (Strengths and Difficulties Questionnaire; Goodman, 1997 ), and video‐based coding of the toddlers in 20‐minutes dyadic play with (i) mothers and (ii) familiar peers. Results. Relations between the three measures of positive behaviour were rather modest, and only significant for the association between maternal ratings and observed positive behaviours with peers. Maternal ratings of prosocial behaviour were significantly correlated with performance on the emotion‐understanding tasks, even when age effects were controlled. Together, emotion understanding and verbal ability explained over half the variance in maternal ratings of prosocial behaviour; unique predictive effects were significant for emotion understanding but not verbal ability. Further, emotion understanding mediated the relationship between verbal ability and mothers' ratings of prosocial behaviour. Conclusions. These findings highlight the importance of emotion understanding as a proximal influence on very early prosocial behaviour.     

Why some surprises are more surprising than others: Surprise as a metacognitive sense of explanatory difficulty

Early theories of surprise, including Darwin’s, argued that it was predominantly a basic emotion. Recently, theories have taken a more cognitive view of surprise, casting it as a process of “making sense of surprising events”. The current paper advances the view that the essence of this sense-making process is explanation; specifically, that people’s perception of surprise is a metacognitive estimate of the cognitive work involved in explaining an abnormal event. So, some surprises are more surprising because they are harder to explain. This proposal is tested in eight experiments that explore how (i) the contents of memory can influence surprise, (ii) different classes of scenarios can retrieve more/less relevant knowledge from memory to explain surprising outcomes, (iii) how partial explanations constrain the explanation process, reducing surprise, and (iv) how, overall, any factor that acts to increase the cognitive work in explaining a surprising event, results in higher levels of surprise (e.g., task demands to find three rather than one explanations). Across the present studies, using different materials, paradigms and measures, it is consistently and repeatedly found that the difficulty of explaining a surprising outcome is the best predictor for people’s perceptions of the surprisingness of events. Alternative accounts of these results are considered, as are future directions for this research.     

Language counts: Early language mediates the relationship between parent education and children's math ability

Children's early math skills have been hailed as a powerful predictor of academic success. Disparities in socioeconomic context, however, also have dramatic consequences on children's learning. It is therefore critical to investigate both of these distinct contributors in order to better understand the early foundations of children's academic outcomes. This study tests an integrated model of children's developing math ability so as to (1) identify the specific skills and abilities most clearly linked to early math achievement and (2) measure the influence of children's socioeconomic context on each of these skills. We first evaluated the early vocabulary, number word knowledge (knower level), and Approximate Number System (ANS) acuity of a diverse group of preschoolers. Then, approximately 1 year later as they entered Kindergarten, we administered a test of early math achievement. We find that children's early language (general vocabulary and number word knowledge) fully mediates the relationship between parent education and math ability. Additionally, number word knowledge mediates the relationship between ANS acuity and early math. We argue that increased focus on number word knowledge, as well as general vocabulary, may help to minimize disparities in math ability as children enter kindergarten. We also highlight the role of parent education on children's learning and note that this may be an important locus for intervention.
