Art-Based Antecedent Intervention to Support On-Task Behavior for Preschool Children with Disruptive Behavior

Stuebe, Susan Martignetti 31 July 2018 (has links)
<p> 2-Shapes (Stuebe, 2017), an art-based antecedent intervention, was introduced as an intervention to regulate disruptive behaviors in this study. The researcher was interested in discovering whether this art-based antecedent activity could help manage self-regulation in a K3 student during group time. The goal of this art-based antecedent study was to provide a meaningful intervention to a child that supports self-regulation, improves self-awareness, and supports intrapersonal and interpersonal thought processes to manage changing conditions. The results of the study revealed the importance of completing a thorough Functional Behavioral Assessment followed by a Functional Analysis to understand the function of a class of disruptive behaviors exhibited by a K3 child. The interview process prior to any assessments may answer many of the questions researchers have about the function of target behaviors and should be completed thoroughly with a great deal of thought and detail. This study demonstrated the need for addressing these steps in determining an appropriate intervention. Results from a Functional Analysis performed after the data collection process determined that the function of the disruptive behavior was attention and that this intervention, if proven effective, would have been addressing the function of attention and therefore would have been an effective treatment for the identified child. </p><p>

A quantitative examination of ostensibly extrasensory experiences occurring spontaneously and in laboratory conditions

Roberts, B. L. H. January 2013 (has links)
Parapsychological research, including the examination of the anomalous process termed ‘psi’, is highly controversial, with the existence of psi not accepted by mainstream science. The aim of this thesis was to study one aspect of psi, extrasensory perception (ESP), to examine whether evidence for ESP could be obtained or whether ostensibly extrasensory experiences can be attributed to purely psychological processes. Three studies are reported. The first obtained reports of spontaneous cases of ostensible ESP from 94 participants, using an online survey. Participants described their experience and responded to a series of questions regarding the aftermath of their experience and their reasoning for a paranormal interpretation. Results demonstrated several patterns that replicated earlier findings, including the predominance of female percipients, serious events, and close relationships between the percipient and target person. Negative emotions were common, including shock and confusion, particularly at the point of ostensible confirmation of the experience; the most common long-term response was an increase in paranormal belief, although some participants were relatively unaffected. Approximately two-thirds of participants had considered viable normal explanations for their experience, including coincidence and expectation of likely outcomes. Paranormal explanations were commonly attributed to the lack of a viable normal explanation, the striking coincidence between the experience and event, or the unusual nature of the experience. Many cases were weak evidentially; findings overall suggest that many ostensibly extrasensory experiences may have non-psi explanations. Two subsequent studies examined ESP in laboratory conditions, using the ganzfeld paradigm. Based on findings from spontaneous case research and previous laboratory studies, it was examined whether success was related to the emotional bond between pairs of participants, or to their sexes. The first study employed 30 pairs of participants, each taking part once as sender and once as receiver. Picture postcards were used as targets, and an emotional connectedness scale was used to assess pairing closeness. Direct hits and binary hits were above mean chance expectation (MCE); both were non-significant, although binary hitting was only marginally so. Results were suggestive of improved performance for closer pairings and mixed-sex pairings, but were non-significant. The second study was a partial replication, with 40 pairs of participants and using video clips as targets. EEG recordings were taken from the frontal midline (Fz) site of both participants. Approximately half of senders experienced stroboscopic stimulation at 6Hz throughout the trial in an attempt to drive theta rhythms associated with a hypnagogic state, mirroring the state expected in receivers due to ganzfeld stimulation. Direct hits were at MCE, while binary hits were non-significantly above MCE; binary hitting across the two studies was significant. There was no effect of pairing closeness or sexes on success, and hitting was not associated with any EEG features or with strobe usage. Overall, laboratory findings appeared promising in terms of significant binary hitting but continued a trend of inconsistency within and between ganzfeld ESP studies. This inconsistency, together with the many weakly evidential spontaneous cases collected, point more strongly to a psychological interpretation of ostensibly extrasensory experiences, rather than the elusive psi.

Food restriction and polyunsaturated fatty acids enriched diet attenuate learning and memory impairments following global ischemia in rats

Roberge, Marie-Claude January 2008 (has links)
L'objectif principal de cette these etait de caracteriser l'impact d'une consommation alimentaire quotidienne reduite en calorie ou enrichie de gras polyinsatures (PUFA) sur les repercussions neuronales et fonctionnelles d'une ischemie cerebrale globale. Differents groupes de rats furent assignes aleatoirement aux conditions experimentales, determinees par la diete consommee et la procedure chirurgicale administree. Les regimes alimentaires des deux premieres etudes de cette these incluaient l'ingestion alimentaire ad libitum ou une restriction alimentaire de 40% comparee a l'ingestion des rats des groupes ad libitum. Dans une troisieme etude, nous avons evalue l'impact de la consommation d'une diete enrichie de gras polyinsatures de type omega 3 et omega 6, via l'ajout de 11.5% d'huile de poisson et de 3.5% d'huile de mais a la diete controle. Ces differentes dietes furent toutes initiees chez des rats ages de 4 semaines et maintenues pendant une periode de 18 semaines (pre et post-chirurgie). Les procedures chirurgicales, administrees durant la 13ieme semaine d'ingestion alimentaire, incluaient soit une chirurgie vasculaire impliquant 8 ou 12 minutes d'ischemie cerebrale globale ou une operation controle (chirurgie sham). Suite a ces procedures, l'administration d'une serie de paradigmes comportementaux debuta pour l'ensemble des animaux au 4ieme ou 5ieme jour suivant la chirurgie, et se terminant 7, 31 ou 70 jours suivant l'ischemie, dependamment de l'experimentation. Les tests comportementaux utilises incluaient l'aire ouverte, le labyrinthe en croix et le labyrinthe radial a huit bras. A l'instar des recherches suggerant des effets neuroprotecteurs de la restriction alimentaire et de l'ingestion de supplements d'acides gras polyinsatures, nos resultats demontrent que la survie neuronale dans le CA1 de l'hippocampe est comparable entre les rats ischemies nourris des dietes experimentales et ceux nourris a volonte. Cette absence de difference s'observe 7, 31 et 70 jours suivant la procedure chirurgicale. Egalement, nos resultats comportementaux revelent une reduction significative, voire la prevention, des deficits d'apprentissage et de memoire spatiale induits par l'ischemie globale chez les rats restreints et nourris d'une diete enrichie de PUFA. Les performances mnesiques de ces animaux sont comparables a celle des rats controles et significativement meilleure que celle des rats ischemies nourris d'une diete reguliere. Fait plus impressionnant, les animaux ischemies restreints demontrent egalement la capacite de completer une serie de taches differees complexes appariees ou non a l'echantillon (DMTS/DNMTS) dans le labyrinthe radial, contrairement aux rats ischemies nourris a volonte. Nos resultats suggerent que la restriction alimentaire et l'ingestion de supplements d'acides gras polyinsatures induisent des changements plastiques et/ou l'activation de mecanismes endogenes compensatoires capables de proteger les animaux des deficits d'apprentissage et de memoire spatiale generalement produits par l'ischemie globale.
