An attenuation of the 'normal' category effect in patients with Alzheimer's disease: a review and bootstrap analysis

There is a consensus that Alzheimer's disease (AD) impairs semantic information, with one of the first markers being anomia i.e. an impaired ability to name items. Doubts remain, however, about whether this naming impairment differentially affects items from the living and nonliving knowledge domains. Most studies have reported an impairment for naming living things (e.g. animals or plants), a minority have found an impairment for nonliving things (e.g. tools or vehicles), and some have found no category-specific effect. A survey of the literature reveals that this lack of agreement may reflect a failure to control for intrinsic variables (such as familiarity) and the problems associated with ceiling effects in the control data. Investigating picture naming in 32 AD patients and 34 elderly controls, we used bootstrap techniques to deal with the abnormal distributions in both groups. Our analyses revealed the previously reported impairment for naming living things in AD patients and that this persisted even when intrinsic variables were covaried; however, covarying control performance eliminated the significant category effect. Indeed, the within-group comparison of living and nonliving naming revealed a larger effect size for controls than patients. We conclude that the category effect in Alzheimer's disease is no larger than is expected in the healthy brain and may even represent a small diminution of the normal profile.     

Benevolent Sexism Toward Men and Women: Justification of the Traditional System and Conventional Gender Roles in Spain

The present study aimed to explore sexist attitudes in young people and to investigate the role of these ideologies in the contribution of boys and girls to housework. For this purpose, 139 Spanish high school students (67 females and 72 males) responded to the ASI and AMI scales (Glick and Fiske in Journal of Personality and Social Psychology 70:491–512, 1996, Psychology of Women Quarterly 23:519–536, 1999) and assessed their contribution to housework in tasks considered traditionally done by women (highly gender-typed) or more neutral tasks (sex-neutral). Results showed that girls contributed significantly more to housework than boys. In addition, correlation analyses showed that benevolent sexism toward women, men and hostility toward men were significant related to highly gender typed tasks only in the female sample. This result shows the relevance of sexist ideologies in maintaining established differences between genders.     

Interactions between CO2 oral pungency and taste

Two experiments are reported in which the perceptual interactions between oral pungency, evoked by CO2, and the taste of each of four tastants--sucrose (sweet), quinine sulfate (bitter), sodium chloride (salty), and tartaric acid (sour)--were explored. In experiment 1 the effect of three concentrations of each tastant on the stimulus-response function for perceived oral pungency, in terms of both rate of change (slope) and relative position along the perceived pungency axis, was determined. In experiment 2 the effect of three concentrations of CO2 on the stimulus-response function for the perceived taste intensity of each tastant was examined. Results show that the characteristics of the mutual effects of tastant and pungent stimulus depend on the particular tastant employed. Sucrose sweetness and CO2 oral pungency have no mutual effect; sodium chloride saltiness or tartaric acid sourness and CO2 oral pungency show mutual enhancement; and quinine sulfate bitterness abates CO2 oral pungency, whereas CO2 has a double and opposite effect on quinine sulfate bitterness--at low concentrations of bitter tastant CO2 enhances bitterness, and at high concentrations of bitter tastant CO2 abates bitterness. It is suggested that the perceptual attributes of saltiness and sourness are closer, from a qualitative point of view, to oral pungency than are the attributes of bitterness and sweetness.     

Gathering Diverse Perspectives to Tackle “Wicked Problems”: Racial/Ethnic Disproportionality in Educational Placement

Among students receiving behavioral health and special education services, racial/ethnic minority students are consistently overrepresented in settings separate from general classrooms. Once separated, many young people struggle to improve academically and face significant difficulty upon trying to return to a general education setting. Given the complex, ongoing, and multifaceted nature of this challenge, racial/ethnic disproportionality can be identified as a “wicked problem,” for which solutions are not easily identified. Here, we describe our community-engaged research efforts, eliciting perspectives from relevant partners in an ongoing dialogue, to better integrate diverse stakeholders’ perspectives when attempting to address such disparities. We conducted focus groups and qualitative interviews with members of three stakeholder groups: community-serving organizations, individuals with lived experience of behavioral health conditions, and state-level policymakers, with a shared interest in addressing racial and ethnic disparities. Participant responses illustrated the “wickedness” of this problem and highlighted the need for additional supports for students, families, and school personnel, increased collaboration across relevant systems and agencies, and reduced barriers related to funding. Overall, this methodology bridged differing perspectives to develop, in concert with our partners, a shared language of the problem and a core set of issues to consider when seeking to effect change.

Doctors' decision-making on giving information to cancer patients

Abstract

A major focus in the literature about doctor-patient communication is information-giving. In the case of cancer patients, one significant issue is which factors determine whether and how, general practitioners and oncologists give information to their patients. Whatever may be the content of information, the most important choice for the doctor is to give information or not. Our research group at the Department of Health Psychology has conducted investigations in order to identify the significant determinants of decisions concerning giving information to cancer patients. A sample of 60 doctors from Alicante province in Spain were asked their criteria for giving information about a cancer diagnosis. Results showed that perceived intelligence and emotional control in the patients were the best predicotrs of the decision by doctors to give information. Age and socio-economic status were also significantly associated with the doctors' information-giving practices. These data suggest that the criteria for giving information to cancer patients are subjective and show a strong cultural influence.
