This paper analyses a lecture by an excellent teaching award winner professor of mathematics, given to high school mathematics teachers. The analysis is based upon two sources: (i) the lecture plan, as expressed in a series of 29 transparencies, prepared by the lecturer in advance; (ii) the actual implementation of the lecture, as transcribed from…

This study examined the effects of manipulating establishing operations on the frequency of initiations of three children with autism toward peers with autism. The EO targeted was deprivation of preferred edibles, and the target initiation was a mand for the preferred snack. A reversal design was used to assess the effects of the EO conditions on…

Some evolutionary cognitive and developmental psychologists propose that the human mind consists of domain-specific modules. These are characterized as self-contained "mini-computers" that process information of a certain kind. In their book, "Original Intelligence," the Premacks set out to provide a synthesis of evidence from various fields in…

The motivational function exerted by verbal antecedents has been extensively approached from a theoretical perspective and within the direct conditioning paradigm. However, there is little research concerning the alteration of the motivational function via verbal means. The current study presents 2 consecutive experiments in which the role of the…

For more than 25 years people have known that children and adults with Down syndrome have a specific impairments in working memory. Within the working memory system, they have particular difficulty with the verbal short-term memory part of the system. However, memory training may become more popular as recent work with both children with Down…

This study examined the relation between early television exposure and parental interaction style during infant-directed television programs on 2 outcomes: infant looking time and infant responsiveness. By quasi-experimental design half of the 12- to 18-month-old infants had prior exposure to the program content and the other half did not. Cluster…

Lesbian, gay, bisexual, and transgender (LGBT) youth may face particularly hostile school climates, as they often report experiencing harassment, discrimination, and other negative experiences in school. LGBT youth, regardless of their gender identity, often face victimization and stigmatization based on both sexual orientation and gender…

Turkish mothers' self-efficacy beliefs and their interactional behaviors with their children with language delays are described and explored. Participants included 19 mother-child dyads. Mothers' interaction with their children with language delays was videotaped for 30 minutes in a free-play context. Regarding mothers' interactional behaviors,…

Introduction: Aggressive behaviours can be disabling for adults with intellectual disabilities (ID), with negative consequences for the adult, their family and paid carers. It is surprising how little research has been conducted into the epidemiology of these needs, given the impact they can have. This study investigates point prevalence, 2-year…

Selective Mutism (SM) in children and adolescents is characterized by a persistent failure to speak in certain social situations including at school or with friends despite the ability to speak and comprehend language. Not due to a specific communication disorder, SM is actually a pervasive psychological problem that lies along the continuum of…

We compared responding to joint attention (RJA) in younger siblings of children with ASD (SIBS-ASD; n = 46) and younger siblings of children developing typically (SIBS-TD; n = 35). Children were tested between 12 and 23 months of age in a situation in which an experimenter directed the child's attention to one of 8 targets. Each child responded to…

This research studied one aspect of pragmatic language processing, the ability to understand metaphorical language, to determine whether patients with Parkinson disease (PD) are impaired for these abilities, and whether cognitive resource limitations/fronto-striatal dysfunction contributes to these deficits. Seventeen PD participants and healthy…

Verbal reminders play a pervasive role in memory retrieval by human adults. In fact, relatively nonspecific verbal information (e.g. "Remember the last time we ate at that restaurant?") will often cue vivid recollections of a past event even when presented outside the original encoding context. Although research has shown that memory retrieval by…

Background: The study of cerebral specialization in persons with Down syndrome (DS) has revealed an anomalous pattern of organization. Specifically, persons with DS elicit a right cerebral hemisphere lateralization for receptive language and a left cerebral hemisphere lateralization for the production of simple and complex movements: a pattern…

A number of studies have investigated sex differences in the forms of aggression exhibited by adolescent students, particularly in the Western world. No such study has been done among sub-Saharan Africa students. The aim was to examine the sex differences in forms of aggression among adolescent students in Ghana. A total of 800 adolescent students…
