Mother–Son Interactions in Families of Boys With Attention-Deficit/Hyperactivity Disorder With and Without Oppositional Behavior

Parenting responsiveness and over-reactivity were assessed among 25 mothers of 7–9-year-old sons with Attention-Deficit/Hyperactivity Disorder (ADHD) and oppositional behavior (Oppositional Defiant, OD), 24 mothers of sons with ADHD only, and 38 mothers of nonproblem sons. Responsiveness was observed during mother–son play and clean-up interactions and over-reactivity was assessed using self-reports of parenting in discipline situations. Mothers of sons with ADHD/OD were less responsive and more over-reactive than mothers of nonproblem sons, and mothers of sons with ADHD only did not differ from the other groups. Mothers of sons with ADHD/OD reported more hostility than mothers of nonproblem sons, and controlling for maternal hostility eliminated the significant group differences in responsiveness during clean-up and in over-reactivity. Controlling for the childs ADHD subtype did not alter the pattern of results. The implications for addressing responsiveness and over-reactivity as components of parent-mediated behavioral treatments for ADHD are considered.     

Orthographic effects in the word substitutions of aphasic patients: an epidemic of right neglect dyslexia?

Aphasic patients with reading impairments frequently substitute incorrect real words for target words when reading aloud. Many of these word substitutions have substantial orthographic overlap with their targets and are classified as "visual errors" (i.e., sharing 50% of targets' letters in the same relative position). Fifteen chronic aphasic patients read a battery of words and non-words; non-word reading was poor for all patients, and more than 50% of errors on words involved the substitution of a non-target word. An investigation of the factors conditioning these word substitutions, as well as the production of visual errors, identified a number of similarities to patterns previously reported for patients with right neglect dyslexia, which has been said to occur relatively rarely. These included a strong tendency for errors to overlap targets in initial letter positions, maintenance of target length in errors, and the substitution of words higher in imageability than targets. It is proposed that left hemisphere damage frequently leads to disruption of a level of representation for written words in which letter position is ordinally coded, resulting in exacerbation of a normal processing advantage for early letter positions. A computational model is discussed that incorporates this level of representation and successfully simulates relevant normal and patient data.     

Effects of minor phrasing variations in traffic-related questionnaires – Comparison of objective equivalences and respondents’ subjective statements

This paper examines questionnaire-related issues of variations in the wording of questions and the objective accuracy of the response, in terms of three traffic-related phenomena (accident frequency, incident frequency, and speeding). ca. 900 survey respondents, living along four major arterial streets in Malmö, Sweden, estimated the occurrence of the phenomena in question. The dispatch consisted of two parallel questionnaires with minor variations in question wording which showed significant differences in the given estimates of accident and incident frequency depending on the phrasing. The correspondence between the subjective estimates and objectively measured accident and speeding figures is discussed along with the potential impact of wording, the phenomenon’s characteristics and response scales. Increased knowledge of these factors could ease communication with the public in the municipal traffic-planning process.
