Starting with the "right" foot minimizes sprint start time

Although asymmetries in hand and foot performance have been examined using a variety of movement tasks that require the fine control of the timing and amplitude of force generation, foot asymmetries in a functional gross motor movement task, such as the track and field sprint start, have yet to be examined. Twenty individuals (10 experienced, 10 inexperienced) were assessed for pedal asymmetries using the track and field sprint start. Each participant performed 48 starts (24 right foot starts and 24 left foot starts). The pattern of pedal asymmetries was consistent with that of manual asymmetries in that a left foot (i.e., left foot in rear position) reaction time advantage was found while there was a right foot (i.e., right foot in rear position) advantage for movement time and total response time (time from stimulus presentation until the end of the movement). These results are consistent with a right hemisphere specialization for spatio-temporal and attentional processes, and a left hemisphere specialization for movement execution.     

The Integration of Body Movement and Attention in Young Infants

The normal development of adaptive behavior in humans depends on the integration of visual attention and body movement, yet little is known about the initial state of movement-attention coupling at the beginning of postnatal life. We studied 1- and 3-month-old infants during extended periods of visual exploration and found that spontaneous shifts of gaze are preceded by rapid changes in general body movement. The results reveal a tight link between motor activation and overt attention on a time scale of seconds or less. This link undergoes substantial developmental change in the first few weeks after birth. During that time, phasic motor activation may play a key role in visual exploration by helping to unlock gaze when the environment is unchanging.     

The effects of nicotine on Parkinson's disease

Post-mortem studies have demonstrated a substantial loss of nicotinic receptors in Parkinson's disease (PD), which may be at least partially responsible for some of the cognitive, motoric, and behavioral deficits seen in this disorder. Epidemiologic studies have suggested that cigarette smoking is a strong negative risk factor for the development of PD. We have previously shown that blockade of central nicotinic receptors produces cognitive impairment in areas of new learning, short-term memory, and psychomotor slowing with increasing dose sensitivity with age and disease. Studies of acute stimulation of nicotinic receptors in Alzheimer's disease with nicotine and the novel agonist ABT-418 in our laboratory and others have shown improvements in several measures of cognitive function. Prior studies of the effects of nicotine in PD have suggested some improvements in clinical symptomatology. We have begun quantitative studies of both acute and chronic nicotine in PD to assess both cognitive and motor effects. Fifteen (15) nondemented subjects (age 66 +/- 5.3; M/F = 11/4) with early to moderate PD (mean Hoehn-Yahr stage = 1.77; MMSE = 28.6) received a dose-ranging study of intravenous nicotine up to 1.25 microg/kg/min, followed by chronic administration of nicotine by transdermal patch with doses ranging up to 14 mg per day for 2 weeks. Testing occurred both during drug administration and up to 2 months after drug cessation to look for prolonged effects. Preliminary analysis shows improvements after acute nicotine in several areas of cognitive performance, particularly measures such as reaction time, central processing speed, and decreased tracking error. Improvements in attention and semantic retrieval were not seen. After chronic nicotine, improvements were seen in several motor measures suggesting improved extrapyramidal functioning. This appeared to be sustained for up to 1 month after drug. The treatment was well tolerated. Nicotinic stimulation may have promise for improving both cognitive and motor aspects of Parkinson's disease.     

OVERCOMING AN AUTISTIC CHILD'S FAILURE TO ACQUIRE A TACT REPERTOIRE

A 6-year-old nonvocal autistic girl who had acquired over 30 signs as mands (requests), simple intraverbals (English-sign translations), and imitative responses repeatedly failed to acquire a tact (labeling) repertoire. It was speculated that the verbal stimulus “What is that?” blocked the establishment of stimulus control by nonverbal stimuli. When procedures to transfer stimulus control from verbal to nonverbal stimuli were implemented, the subject quickly learned to tact all 18 target stimuli.     

RECONFIRMATION OF THE SHORT-TERM STORAGE CONCEPT

Abstract— Recent research questions the existence of a short-term storage mechanism capable of holding limited information temporarily Specifically, serial-recall results with a through-list distractor (TLD) procedure, in which a distracting task is interposed between list Items as well as between the list and recall period, generally resemble the results of immediate-recall procedures The present study, however, reconfirms the utility of short-term storage by demonstrating an important difference between immediate and TLD recall A word-length effect, or advantage for lists of shorter words (which minimize short-term forgetting during spoken recall), did not occur with a TLD procedure.     

The Effects of Names on Perception of Intelligence, Popularity, and Competence

Three experiments were conducted to explore the effects of first names on judgments of intelligence, popularity, and competence. In Experiment 1, first names that were used more often in the past than they are now (called Older Generation names) were rated by a sample of college-aged judges as less popular and less intelligent than were first names that are used more often now than in the past (called Younger Generation names). In addition, male first names tended to have higher ratings of these same qualities than did female first names. In Experiments 2 and 3, either resumes or personal ads were used to provide additional information to the raters. Results similar to those found in Experiment 1 were obtained. In general the present experiment used groups of names rather than individual names so as to control for possible irrelevant and idiosyncratic differences that might be found among individual names. Relevance to research in which men and women are compared was discussed.     

Description of a Behavioral Intervention to Reduce Substance Use and Related Risk and Increase Positive Parenting among Urban Mothers with Alcohol and Other Drug Problems

The abuse of alcohol and other substances by mothers raising adolescent children has serious adverse effects on family functioning and youth outcomes, and on mothers’ own health and adaptation. Mothers who are also HIV-infected face additional challenges. In the present report, we describe a multi-session intervention conducted in individual sessions for mothers with alcohol and other substance use problems who are raising adolescent children. We outline the primary components of the intervention and include case studies and examples of exercises and tools. We found that engagement with the intervention and high rates of attendance were facilitated by tapping into mothers’ desires to improve their relationships with their adolescent children, the use of a harm reduction approach toward substance use, and intensive outreach. We also discuss lessons learned in the course of implementing and evaluating the intervention.     

Perceived stigma,self-blame,and adjustment among lung,breast and prostate cancer patients

People who suffer from disease have often been stigmatised. The internalisation of stigma leads to the experience of self-blame. The relationship among stigma, self-blame and adjustment was framed with two theoretical perspectives: the looking-glass self and learned helplessness models. These models were studied in 96 lung, 30 breast and 46 prostate cancer patients. Consistent with the looking-glass-self model, we predicted that perceived stigma and self-blame would be associated with poorer psychological adjustment; the data supported these hypotheses. Consistent with the learned helplessness model, we predicted that self-blame would mediate the link between perceived stigma and psychological adjustment; data supported these hypotheses. The mediation model explained a greater percentage of the variance in adjustment in the lung cancer sample compared to the breast and prostate cancer sample. Participants who reported internal causal attributions reported poorer psychological adjustment. Lung cancer patients were more likely than breast or prostate cancer patients to report internal causal attributions for their cancer. Future research and cancer care are discussed in light of these findings.     

Guidance counselling as a whole school responsibility in the Irish post primary sector

ABSTRACT

This paper will deliberate upon the relevance of guidance counselling as a ‘whole school’ responsibility in the context of recent policy and practice changes in the Irish post primary sector since the Government of Ireland Budget 2012. Pertinent issues including the complexities of delivering a whole school approach to guidance counselling during a period of resource rationalisation will be addressed through the findings from recent case study research [Hearne, L., Geary, T., & Martin, N. (2016). A single case study of a whole school approach to guidance counselling in an Irish post-primary school; Case report. Retrieved from University of Limerick website: http://www.ul.ie/soedu/node/1481]. A single explanatory case study methodology investigated the complex phenomenon and interventions of whole school guidance counselling in a mixed gender school in the context of increasing demands for evidence-based data and methodological sophistication in lifelong guidance [European Lifelong Guidance Policy Network.
