The influence of semantic neighbours on visual word recognition

Although it is assumed that semantics is a critical component of visual word recognition, there is still much that we do not understand. One recent way of studying semantic processing has been in terms of semantic neighbourhood (SN) density, and this research has shown that semantic neighbours facilitate lexical decisions. However, it is not clear if this facilitation reflects actual word recognition processes or is instead due to participant strategies used during the lexical decision task. To address this, the current research used college students as participants and tested the effect of SN density using the semantic categorisation and progressive demasking tasks. Both of these tasks require word identification and are not susceptible to the participant strategies that are seen when using the lexical decision task. The results show that SN facilitates responding in both tasks, indicating that SN effects are not due to task‐specific strategies.     

Gender differences in mental simulation during sentence and word processing

Text comprehension requires readers to mentally simulate the described situation by reactivating previously acquired sensory and motor information from (episodic) memory. Drawing upon research demonstrating gender differences, favouring girls, in tasks involving episodic memory retrieval, the present study explores whether gender differences exist in mental simulation in children (Grades 4 to 6). In Experiment 1, 99 children performed a sentence–picture verification task measuring mental simulation at sentence level. In Experiment 2, 97 children completed a lexical decision task in which imageability of words was manipulated to measure mental simulation at word level. Only for girls we found faster reaction times for matching versus mismatching sentence–picture pairs (Experiment 1) and high‐imageability versus low‐imageability words (Experiment 2). The results suggest that girls construct more coherent and vivid mental simulations than boys and rely more heavily on these representations. The results emphasize the importance of including gender into reading comprehension research.

隐喻的表象表征及其加工效应研究

用时间隐喻为研究材料,考查了隐喻表象性与多个心理维度(理解度、熟悉度、喜好度、适当性、重要性)的相关性,并通过比较被试对表象程度不同的时间隐喻在表象加工和语义加工后的语义确认成绩,考查表象加工对时间隐喻表征所产生的加工效应。结果表明时间隐喻表象性与这些心理维度有密切联系;虽然语义表征是时间隐喻表征的基础和起点,但表象表征并不完全是一种附带产物,而是句子表象性程度的函数,在隐喻理解过程中有介入作用。高表象性的隐喻存在双重编码。     

Semantic effects as a function of reading skill in word naming of a transparent orthography

The highly transparent Turkish orthography was employed to examine imageability in relation to level of skill in two experiments. In experiment 1, previously skilled readers (n = 24)named 40 high frequency and 40 low frequency words manipulatedfactorially with imageability. A significant main effect was onlyfound for frequency. In experiment 2, a total of 44 adult Turkishreaders (16 very skilled and 28 skilled) named the same stimulias in experiment 1. The results showed an expected main effectfor skill and frequency. However, whilst the main effect forimageability was nonsignificant, a 2-way interaction of skill byimageability and a 3-way interaction of skill by imageability byfrequency were found to be significant. Very skilled readersnamed high imageable low frequency words significantly fasterthan matched low imageable low frequency words. Insofar as poorreaders are concerned the results are contradictory to previousfindings in English whilst data from highly skilled participantsare in line with those reported for skilled readers for English.Implications of these findings on the existing literature arediscussed.

Reading strategies in Spanish developmental dyslexics

Cross-linguistic studies suggest that the orthographic system determines the reading performance of dyslexic children. In opaque orthographies, the fundamental feature of developmental dyslexia is difficulty in reading accuracy, whereas slower reading speed is more common in transparent orthographies. The aim of the current study was to examine the extent to which different variables of words affect reaction times and articulation times in developmental dyslexics. A group of 19 developmental dyslexics of different ages and an age-matched group of 19 children without reading disabilities completed a word naming task. The children were asked to read 100 nouns that differed in length, frequency, age of acquisition, imageability, and orthographic neighborhood. The stimuli were presented on a laptop computer, and the responses were recorded using DMDX software. We conducted analyses of mixed-effects models to determine which variables influenced reading times in dyslexic children. We found that word naming skills in dyslexic children are affected predominantly by length, while in non-dyslexics children the principal variable is the age of acquisition, a lexical variable. These findings suggest that Spanish-speaking developmental dyslexics use a sublexical procedure for reading words, which is reflected in slower speed when reading long words. In contrast, normal children use a lexical strategy, which is frequently observed in readers of opaque languages.     

The Role of Children's Phonological and Semantic Knowledge in Learning to Read Words

The effect of phonology and semantics on word learning in 5- and 6-year-old children was explored. In Experiment 1, children learned to read words varying in spelling-sound consistency and imageability. Consistency affected performance on early trials, whereas imageability affected performance on later trials. Individual differences among children in phonemic awareness on the trained words were related to learning, and knowledge of a word's meaning predicted how well it was learned. In Experiment 2, phonological and semantic knowledge of nonwords was manipulated prior to word learning. Familiarization with a word's pronunciation facilitated word learning, but there was no additional benefit from being taught to associate a meaning with a nonword.

     

Science and engineering students’ use of diagrams during note taking versus explanation

The use of diagrams in learning and communication is generally considered efficacious and an important skill to cultivate, especially among science students. At the same time, previous research has revealed many problems in student diagram use, including a lack of spontaneity in such use, but the extent to which these problems persist into the tertiary level had not been investigated. The present study examined science and engineering university students’ use of diagrams in note taking to learn information from a written passage, and in a subsequent task of constructing an explanation of that information for another person. The results showed that the students used significantly fewer diagrams in explaining compared to when they were note taking, suggesting that many students may lack awareness of the usefulness of diagrams in effectively communicating information to others. The results also revealed that the students used significantly more diagrams in taking notes from and explaining a passage with higher imageability (i.e. easier to visually imagine) compared to one with lower imageability. Educational implications of the findings are discussed.     

Maternal interaction,private speech,and task performance in preschool children

This study examined the correspondence between ontogenetic and microgenetic change in private speech, the association of private speech with task performance, and the relationship of maternal interaction during a teaching session to preschoolers' verbal self-regulation and success in independent problem solving. Thirty 4- and 5-year-olds were observed while their mothers assisted them in solving two challenging tasks. In three subsequent sessions, children's private speech and performance were tracked as they worked on tasks requiring skills similar to those taught in the mother-child session. Correspondences between age- and session-related trends in private speech and task performance appeared that are consistent with Vygotsky's assumption that private speech undergoes progressive internalization with increasing cognitive competence. Contrary to Vygotskian assumptions, utterances accompanying action were not replaced by those preceding action (planning statements) with advancing age and task mastery. Private speech predicted gain in task performance more effectively than concurrent performance. A global index of authoritative parenting was a better predictor of private speech and task performance than were microanalytic measures of scaffolding, suggesting that microanalytic indices may miss critical features of maternal teaching behavior that promote transfer of cognitive strategies from adult to child.     

Vocabulary learning from reading: examining interactions between task and learner related variables

In the field of second and foreign language learning, how various task characteristics affect language learning has been the focus of many recent studies. Much of this research examined the relationship between task characteristics and task performance without fully taking into account learner related variables. The present study aimed to assess task complexity and sequence in relation to the learner related variables drawn from the social cognitive perspective of self-regulated learning, i.e. self-efficacy beliefs and frequency of learning strategy use, as they were applied to two versions of vocabulary learning from reading tasks. The tasks designed for the present study were based on the componential framework for second language task design. With tasks and task sequence counterbalanced, 146 first-year university students (mean age?=?18.59 years) were randomly assigned to one of four groups. Results reveal a significant effect of task sequence on vocabulary learning self-efficacy beliefs, frequency of learning strategy use and task performance, and a significant interaction effect of sequence with task complexity. Findings are discussed in terms of complex interactions between task and learner factors.

Vulnerability in Research: A Developmental Perspective on Research Risk

Assessing potential risks to children who participate in developmental research is a challenging task because children are a heterogeneous population, varying in developmental competencies and in background characteristics. This essay offers a developmental perspective on research risk, emphasizing that children's vulnerability to research risk changes in complex ways: some risks decrease with increasing age, some increase as the child matures, others change in a curvilinear fashion, while some remain essentially stable with development. Because vulnerability in research does not simply decline linearly with age, assessments of research risk must entail multidimensional considerations that vary over developmental time. In a similar manner, individual characteristics of children at any age (e.g., maltreatment, at-risk status, etc.) may also heighten their vulnerability to certain risks which require special consideration by researchers. Finally, this discussion of developmental vulnerability and the principles underlying research ethics suggests that in addition to the conventional risk/benefit analysis, researchers are in an optimal position to establish and maintain standards of decent treatment of children in research that safeguard their rights as research participants. Suggestions for fostering this process in the research community are outlined.

Training Teachers in Mixed‐age Classrooms: effects of a staff development programme

A quasi‐experimental, treatment‐control group investigation was designed to test the effects of the staff development programme Dealing with Mixed‐age Classes. Research findings from mixed‐age glasses, effective teaching and classroom management and organisation were translated into teacher behaviours. Following seven three‐hour workshops teachers in mixed‐aged classes implemented self‐designed plans to increase selected research‐derived teaching behaviours and pupils’ time‐on‐task. Based on pre‐ and post‐training classroom observations, a significant treatment effect was found for pupils’ time‐on‐task levels in mixed‐age classrooms and for teacher behaviours regarding effective instruction, lesson design and execution, classroom organisation and management.     

Attending to spatial locations: a developmental study

In 2 experiments, 7- and 8-year-old children and college students performed a letter-detection task in which reaction time was the dependent variable. Expectancy was manipulated by varying the probability the stimulus would appear at the center of an imaginary circle rather than along the perimeter. Although both age groups responded consistently faster to stimuli presented in expected locations than to stimuli presented in unexpected locations, this expectancy effect was larger for the children than it was for the college students. In a third experiment, these results were replicated using a luminance-detection task with 5-year-olds, 8-year-olds, and college students as subjects. It was concluded that children as well as adults are able to expand or contract the breadth of their attentional focus in accordance with task demands and that there is a developmental change in the efficiency with which a stimulus presented in an otherwise empty field can be located. Furthermore, it was suggested that children may be more disrupted by the occurrence of an unexpected event than adults are.     

The vice and virtue of conflict in boards: A longitudinal study into the effect of conflicts and cohesion on the task performance of supervisory school boards in the Netherlands

The increased diversity and autonomy of schools calls for a more professional approach to school governance. In response, attention has been directed to the structure of school boards in the Netherlands. However, previous research indicates that the effectiveness of governance is not so much about structure as it is about behaviour. Conflict, in particular, appears to be an important underexposed factor in the effective behaviour of school boards. In a longitudinal research design, a survey using Likert-scale items was distributed in 2016 and 2017 to executive directors of schools in the Netherlands to gauge their assessment of conflicts within the supervisory school board. Hierarchical regression analyses and moderator analyses were used to test the hypotheses. An increase in task-related conflicts were found to have a clear positive effect on the task performance of supervisory boards. An increase in numbers of relational conflicts had a negative effect on the control task performance, while an increase in process-related conflicts had a negative effect on the advisory task performance. The cohesion within a supervisory board proved to be an important moderator of the effect of task-related conflicts and relationship conflicts on the control task performance. The results from this research underline the need for a multidimensional conceptualisation of conflict in supervisory boards. The need for further research on the interaction between cohesion and conflicts is underscored. Boards should make room for substantive debate and even for the inevitable friction and irritation that is sometimes inherent in being effective in managing schools.     

Executive function and verbal self-regulation in childhood: Developmental linkages between partially internalized private speech and cognitive flexibility

Recent studies have noted that executive function and the use of self-regulatory private speech are related in childhood, and proposed that the critical leap that occurs in the development of executive function between the ages of three and six years may be due to the onset of language-based self-regulatory functions at this age. This research explored the relationship between executive function and private speech in a cross-sectional study of 81 children between four and seven years of age. The children performed an executive function task, the Dimensional Change Card Sort (DCCS), and children's use of private speech was observed during a categorization task. The results indicated that, after controlling for children's age, gender, verbal abilities, and fluid reasoning, children's use of partially internalized private speech during the categorization task was significantly related to the number of phases successfully passed on the DCCS task, which required them to switch between card sorting rules. Children who used more partially internalized private speech were more likely to pass the most challenging phase of the DCCS task that assesses the ability to flexibly use different sorting rules according to a higher-order rule. We discuss the role of verbal mediation in the development of cognitive flexibility and its implications for the design of intervention programs for children who possess deficits of executive function.     

The impact of remembered success experiences on expectancies,values, and perceived costs

The “remembered success effect” (Finn, 2010) refers to the finding that challenging academic tasks that start or end with extra opportunities for success are often preferred to challenging tasks that do not include these opportunities. Research on the remembered success effect has identified some memory processes that are thought to give rise to the effect. To date there has been no research on how experiences of remembered success relate to motivational constructs that may be associated with the effect. Accordingly, we examined how challenging math experiences designed to induce remembered success impacted individuals’ expectancies for success, positive task value and perceived costs, and how these motivational constructs related to two future task choices; expectancy-value theory posits that expectancies and task values are the most direct motivational predictors of choice. In two studies, participants completed two challenging math tasks under two conditions: a short task of all difficult problems and a longer, “extended” task that had the same number of difficult problems plus a set of moderately difficult problems. Results demonstrated that expectancies and subjective task value were higher, and perceived costs lower in the “extended” condition than in the short condition. In both experiments, the between-task difference scores (i.e., extended task minus short task) for positive task values, expectancies, and perceived costs were significantly correlated with both task choices. Notably, the positive task value difference score uniquely predicted at least one of the two choices in both experiments. Costs and expectancies were less consistent unique predictors of choice: the between-task difference in perceived costs predicted one choice in Experiment 1, but neither choice Experiment 2, and the difference in expectancies only predicted the choices in Experiment 2.
