Reader and nonreader conception of the spoken word

The development of the concept of word in readers and nonreaders was investigated. Five reader and nonreader male students from four age groups (6.5–7.5; 7.6–8.5; 8.6–9.5; 9.6–10.5) were tested using the procedures developed by J. Downing and P. Oliver (Reading Research Quarterly, 1973–1974, 9, 581–586). Results from an analysis of variance indicated significant effects for reading levels (p < .001), age (p < .05), stimuli (p < .01), and a significant interaction between reading level and stimulus class (p < .05). Evidence indicates nonreaders may be confused about the differences between a short word and phonemes, syllables, sentences, and long words.     

The effect of sample and comparison ratio schedules on delayed matching to sample in the pigeon

In Experiment 1, three food-deprived pigeons received trials that began with red or green illumination of the center pecking key. Two or four pecks on this sample key turned it off and initiated a 0- to 10-sec delay. Following the delay, the two outer comparison keys were illuminated, one with red and one with green light. In one condition, a single peck on either of these keys turned the other key off and produced either grain reinforcement (if the comparison that was pecked matched the preceding sample) or the intertrial interval (if it did not match). In other conditions, 3 or 15 additional pecks were required to produce reinforcement or the intertrial interval. The frequency of pecking the matching comparison stimulus (matching accuracy) decreased as the delay increased, increased as the sample ratio was increased, and decreased as the comparison ratio was increased. The results of Experiment 2 suggested that higher comparison ratios adversely affect matching accuracy primarily by delaying reinforcement for choosing the correct comparison. The results of Experiment 3, in which delay of reinforcement for choosing the matching comparison was manipulated, confirmed that delayed reinforcement decreases matching accuracy.     

Relational and Overt Aggression in Disruptive Adolescents: Prediction from Early Social Representations and Links with Concurrent Problems

Children's representations of conflict and distress situations at 7 years were examined as developmental precursors to relational aggression, overt aggression, and psychiatric symptoms in early adolescence. Children were identified in early adolescence. Children were identified in preschool as normally developing or with behavior problems. Overt, but not relational, aggression, was correlated with concurrent disruptive symptoms in adolescence. Childhood predictors of adolescent aggression were found only for girls: Early hostile themes predicted more relational and overt aggression, while prosocial themes predicted less relational aggression. Also for girls only, early emotions foretold later functioning: Sadness predicted a higher ratio of relational to overt aggression, while inexpressiveness predicted disruptive, anxiety, and depressive symptoms. Relational and overt aggression are discussed with regard to sex differences in symptom changes over time.     

The ABCs of family mealtimes: observational lessons for promoting healthy outcomes for children with persistent asthma

Family mealtimes have the potential to promote healthy child development. This observational study of 200 family mealtimes examined the relation between child health in a group of children (ages 5 to 12) with persistent asthma and 3 dimensions of mealtime interaction: Action, Behavior Control, and Communication. Percent time spent in Action and Positive Communication varied by asthma severity, child quality of life, and sociodemographic variables. Positive communication during mealtimes predicted child quality of life. Significant interactions between demographic variables and behavior control suggested that higher levels of behavior control affected child quality of life in the context of lower maternal education. Guidance is offered for practitioners and policy makers toward promoting healthy family mealtimes as a public health priority.     

Determinants of range effects in face recognition

The effects of test stimulus range on generalization gradients in humans were assessed for discriminations between faces that varied in brightness, faces that varied in orientation in the picture plane, and morphed faces. In Experiment 1, significant range effects, predicted by adaptation level theory, occurred when faces varied along the brightness or orientation dimension, but not for morphed faces. Changing the difficulty of discrimination of both training and test stimuli for Experiment 2 produced range effects in morphed faces. Experiment 3 explored training and testing stimulus factors as determinants of range effects in morphed faces. The results suggest that sufficiently biased testing ranges create shifts in response distributions (generalization gradients), and this may be amplified by using relatively difficult discriminations between training stimuli.     

Is Your Tutorial Pretty or Pretty Useless? Creating Effective Tutorials with the Principles of Multimedia Learning

ABSTRACT

With the proliferation of free and easy-to-use tools to make online tutorials, many libraries have been creating online tutorials for their users. These cover everything from showing users how to navigate the databases to covering issues like copyright and evaluation. While the tutorials range from entertaining to rather dry, many of them, regardless of their entertainment value, do not employ the methods that can lead to deeper learning. Mayer (2014a Mayer, R. E. (Ed.). (2014a). The Cambridge handbook of multimedia learning. New York, NY: Cambridge University Press. [Google Scholar]) has explored the concepts and research around online tutorials in The Cambridge Handbook of Multimedia Learning. The principles covered in the handbook and in the related research can be quite counterintuitive for those of us who create online tutorials. This article explores these principles as they relate to tutorials created for library instruction. Additional research to expand on and support Mayer's principles will be discussed to provide evidence-based strategies for deepening learning and reducing elements that detract from learning.     

Gaining and Sustaining TEL in a 1:1 Laptop Initiative: Possibilities and Challenges for Teachers and Students

The uptake and use of digital technologies is studied in Unos Umeå, a joint one-to-one (1:1) research project between Umeå University and the municipality of Umeå in Sweden. This article presents the results of the third phase of the classroom work with laptops. Using the ecology of resources model (Luckin, 2010), these possibilities and challenges can be interpreted as the manifestation of filters in the learning environment. Alleviating technical problems, targeting low student laptop use, teacher collaboration, and teacher professional development (TPD) may help teachers and students gain and sustain technology-enhanced learning (TEL) in this 1:1 initiative.     

Attitudes and mainstreaming: A literature review for school psychologists

“Mainstreaming” legislation requires that special needs students participate in regular classroom activities to the extent possible. Studies indicate, however, that, neither parents, peers, nor professionals may be expected to hold positive attitudes toward these students or be competent providers of positive growth experiences. Existing evidence supports the need for comprehensive training programs for these groups which provide an interface between their experiences with special needs students and an introduction to new knowledge. School psychologists should assume a leadership role in development and implementation.
