Teachers' knowledge, misconceptions, and lacks concerning Attention Deficit Hyperactivity Disorder

This study was designed to analyze the knowledge, misconceptions, and lacks about Attention Deficit Hyperactivity Disorder (ADHD) in a sample of 193 teachers, as a replication of the study carried by Sciutto, Terjesen and Bender in 2000. Teachers completed the Knowledge of Attention Deficit Hyperactivity Disorder (KADDS) (Spanish version), adapted by the authors of this research, to measure knowledge of ADHD in three content areas: general knowledge, symptoms/diagnosis, and treatment. Results indicated an average of correct responses of 31.67, 63.88 and 40.46% in general knowledge, symptoms/diagnosis and treatment, respectively. Teachers displayed significantly more knowledge in the Symptoms/Diagnosis scale than in the other scales. Their knowledge correlated positively with: years of experience with hyperactive children, number of hyperactive pupils in their classrooms, and level of perceived self-efficacy. These findings are consistent with those obtained by Sciutto and colleagues.     

Tactile sensitivity of children: effects of frequency, masking, and the non-Pacinian I psychophysical channel

Tactile perception depends on the contributions of four psychophysical tactile channels mediated by four corresponding receptor systems. The sensitivity of the tactile channels is determined by detection thresholds that vary as a function of the stimulus frequency. It has been widely reported that tactile thresholds increase (i.e., sensitivity decreases) as a function of age. However, there is controversial evidence with regard to the progressive loss of sensitivity starting from childhood. In this study, the tactile thresholds of children (n=9, ages 7-11 years) were measured and compared with the thresholds of young adults (n=11, ages 21-27 years). The stimuli consisted of sinusoidal bursts of mechanical displacements, which were applied to the left index fingertips of the participants by using a cylindrical probe (base area=0.126 cm2) without a contactor surround. Absolute thresholds were measured at frequencies of 2, 10, 40, 100, 250, and 500 Hz without masking. The absolute thresholds decreased at high frequencies and were similar to data from the literature except for some discrepancy because of methodological differences. In addition, the threshold of the non-Pacinian I channel was measured at 40 Hz by elevating the thresholds of the Pacinian channel by forward masking. The effects of forward masking in children were similar to results in young adults. In conclusion, there were no significant differences between the tactile thresholds of children and those of young adults at key frequencies: 40 Hz for the Pacinian and non-Pacinian I channels and 250 Hz for the Pacinian channel. These findings contradict the hypothesis that there is gradual loss of tactile sensitivity starting from childhood to early adulthood. The loss of sensitivity due to aging probably is more abrupt and occurs at a later age.

Absence of Ankle Stiffening While Standing in Focus and Cognitive Task Conditions in Older Adults

Abstract

Research suggests that an external focus or cognitive task may improve postural control. Removing attention from movement production may promote automaticity, or the tasks may promote ankle stiffening. To investigate these two theories, twenty older adults stood while performing baseline standing, internal focus, external focus, and two cognitive tasks. Changes in postural control occurred in external focus and cognitive task conditions compared to baseline and internal focus, while no change occurred in cocontraction indices. This suggests that an external focus and cognitive task can improve postural control in older adults. Since no change occurred in cocontraction indices across conditions, this suggests that stiffening cannot explain these changes. Instead, changes could be due to automaticity of sway.     

Viewing Cognitive Conflicts as Dilemmas: Implications for Mental Health

The idea that internal conflicts play a significant role in mental health has been extensively addressed in various psychological traditions, including personal construct theory. In the context of the latter, several measures of conflict have been operationalized using the Repertory Grid Technique (RGT). All of them capture the notion that change, although desirable from the viewpoint of a given set of constructs, becomes undesirable from the perspective of other constructs. The goal of this study is to explore the presence of cognitive conflicts in a clinical sample (n = 284) and compare it to a control sample (n = 322). It is also meant to clarify which among the different types of conflict studied provides a greater clinical value and to investigate its relationship to symptom severity (SCL-90-R). Of the types of cognitive conflict studied, implicative dilemmas were the only ones to discriminate between clinical and nonclinical samples. These dilemmas were found in 34% of the nonclinical sample and in 53% of the clinical sample. Participants with implicative dilemmas showed higher symptom severity, and those from the clinical sample displayed a higher frequency of dilemmas than those from the nonclinical sample.     

Is Moral Theory Harmful in Practice?—Relocating Anti-theory in Contemporary Ethics

In this paper I discuss the viability of the claim that at least some forms of moral theory are harmful for sound moral thought and practice. This claim was put forward by e.g. Elisabeth Anscombe (1981(1958)) and by Annette Baier, Peter Winch, D.Z Phillips and Bernard Williams in the 1970’s–1980’s. To this day aspects of it have found resonance in both post-Wittgensteinian and virtue ethical quarters. The criticism has on one hand contributed to a substantial change and broadening of the scope of analytic moral philosophy. On the other hand it is, at least in its most strongly anti-theoretical formulations, now broadly considered outdated and—to the extent that it is still defended—insensitive to the changes that have occurred within the field in the last 20–30 years. The task of this paper is to relocate the anti-theoretical critique into the field of analytic ethics today.     

Emotion Regulation: Antecedents and Well-Being Outcomes of Cognitive Reappraisal and Expressive Suppression in Cross-Cultural Samples

Habitual emotional state is a predictor of long-term health and life expectancy and successful emotion regulation is necessary for adaptive functioning. However, people are often unsuccessful in regulating their emotions. We investigated the use of cognitive reappraisal and expressive suppression in 489 university students in Norway, Australia, and the United States and how these strategies related to measures of well-being (affect, life satisfaction, and depressed mood). Data was collected by means of selfadministered questionnaires. The major aims of the study were to begin to explore the prevalence of use of cognitive reappraisal and expressive suppression across gender, age and culture, possible antecedents of emotion regulation strategies, and the influence of emotion regulation upon well-being. Results showed that the use of emotion regulation strategies varied across age, gender and culture. Private self-consciousness (self-reflection and insight) was found to be a central antecedent for the use of cognitive reappraisal. Use of emotion regulation strategies predicted well-being outcomes, also after the effect of extraversion and neuroticism had been controlled for. Generally, increased use of cognitive reappraisal predicted increased levels of positive well-being outcomes, while increased use of expressive suppression predicted increased levels of negative well-being outcomes.

Concept of uprightness in baboons: assessment with pictures of realistic scenes

How nonhuman primates process pictures of natural scenes or objects remains a matter of debates. This issue was addressed in the current research by questioning the processing of the canonical orientation of pictures in baboons. Two adult guinea baboons were trained to use an interactive key (IK) on a touch-screen to change the orientation of target pictures showing humans or quadruped mammals until upright. In experiment 1, both baboons successfully learned to use the IK when that key induced a 90 degrees rightward rotation of the picture, but post-training transfer of performance did not occur to novel pictures of natural scenes due to potential motor biases. In Experiment 2, a touch on IK randomly displayed the pictures in any of the four cardinal orientations. Baboons successfully learned the task, but transfer to novel pictures could only be demonstrated after they had been exposed to 360-480 pictures in that condition. Experiment 3 confirmed positive transfers to novel pictures, and showed that both the figure and background information controlled the behavior. Our research on baboons therefore demonstrates the development and use of an "upright" concept, and indicates that picture processing modes strongly depend on the subject's past experience with naturalistic pictorial stimuli.     

Automatic testing of cognitive performance in baboons maintained in social groups

Laboratory procedures used to study the cognitive functions of primates traditionally have involved removal of the subjects from their living quarters to be tested singly in a remote experimental room. This article presents an alternative research strategy favoring testing primates while they are maintained in their social group. The automatic learning device for monkeys (ALDM) is a computerized test system controlled by an automatic radio frequency identification of subjects. It is provided ad lib inside the social group of monkeys, for voluntary self-testing on a 24-h schedule. Nine baboons were tested with ALDM during a 7-month period. Experiments were performed to assess learning in motor control and abstract reasoning tasks. The results revealed high trial frequencies and excellent learning performance, even in tasks involving the highest cognitive complexities. A different study using ALDM with a group of 3 rhesus monkeys revealed social influences on learning. Beyond its interest for cognitive psychologists, ALDM is of interest for pharmacologists and cognitive neuroscientists working with nonhuman primates. ALDM also can serve as an enrichment tool for captive animals and may be used to study a variety of species other than primates.     

Interpreting claims in offender profiles: the role of probability phrases,base‐rates and perceived dangerousness

Offender profilers use verbal and numerical probability expressions to convey uncertainty surrounding claims made about offender's characteristics. No previous research has examined how these expressions might affect the recipient's interpretation of the information. Seventy participants completed an online questionnaire and results showed a diverse range of interpretations of these uncertainty expressions. Moreover, characteristic base‐rates and dangerousness affected the perceived likelihood of the profiling claim, such that increased base‐rates and perceived dangerousness resulted in an increased perception of the claim being likely. Perceived likelihoods also depended on the framing of characteristics as well as the framing of the claim itself. Finally, where claims involved presenting a characteristic qualified by a low probability these claims were interpreted as more likely than not to be present. These findings have practical implications for profilers and more general theoretical implications for the study of risk perception. Copyright © 2008 John Wiley & Sons, Ltd.
