Motivating individuals with autism can be challenging for clinicians and educators seeking to increase skills or decrease problem behaviors. Even when highly preferred reinforcers have been identified, they tend to lose their effectiveness over time. Over the years, several strategies have been developed to maintain the effectiveness of reinforcers. Reinforcer variation has been demonstrated to attenuate decreases in responding associated with repeated exposure to a single reinforcer. Another strategy that has been used to help maintain responding is allowing an individual a choice among reinforcers. Several researchers have suggested that providing choice among several reinforcers may produce the same effects on responding as reinforcer variation. Although these two procedures have been shown to maintain motivation in individuals with autism, they have not been systematically compared and evaluated against each other. In this study, we evaluated the effects of reinforcer variation as compared to reinforcer choice.

OBJECTIVES: The general aim of this research was to analyse the relationships between bullying (as a distinct form of aggression), victimisation, personal and collective self-esteem, and narcissism in adolescents. Baumeister et al. (1996) refuted the conventionally accepted view that low self-esteem is a cause of violence whereby, for example, those who lack self-esteem may use aggression as a means of dominating others and thereby gaining self-esteem. Instead, it may be that aggression is related to high self-esteem such that individuals with a combination of high levels of both self-esteem and narcissism are more likely to react aggressively to a perceived threat. Design: After a conducting a small pilot study (n = 112), the main study employed a large-scale cross-sectional survey with self-report questionnaires administered to school students during class. METHODS: Participants were drawn from six metropolitan high schools in Adelaide (South Australia), resulting in 1,628 adolescents (665 females & 963 males, aged 12-17 years) completing the survey. The questionnaire battery comprised modified self-report bully and victim versions of the Direct and Indirect Aggression Scales (Bjorkqvist et al., 1992), personal (Rosenberg, 1979) and collective self-esteem (Luhtanen & Crocker, 1992) scales, the Narcissistic Personality Inventory (Raskin & Hall, 1981), and a measure of socially desirable responding (i.e., Impression Management; Paulhus, 1991). RESULTS: A variety of multivariate analyses controlling for socially desirable responses was employed to test and explore hypothesised relationships. Results showed no relationship between age and any form of bullying or victimisation. Boys reported significantly higher mean levels of direct and total bullying and victimisation, whereas girls reported higher levels of indirect bullying and victimisation. Victimisation was negatively correlated with personal self-esteem, and positively correlated with collective self-esteem. In contrast, bullying was positively correlated with personal self-esteem, with no significant relationship found with collective self-esteem. Collective and personal self-esteem did not differentially predict different types of bullying or victimisation. Narcissism was positively correlated with bullying. The predicted interaction between personal self-esteem, narcissism and bullying was evident, although the predicted collective self-esteem interaction was not found. Impression Management (social desirability) was significantly negatively correlated with bullying and, to a lesser extent, with victimisation. CONCLUSION: Research such as this into the possible causes and correlates of aggression and bullying will assist in the design, implementation, and maintenance of effective interventions. For example, as results corresponded with Baumeister et al.'s (1996) assertion in that bullying was related to high self-esteem, interventions that are designed to increase self-esteem might in reality be counterproductive and possibly contribute to an increase in bullying behaviour. Additionally, victims reported higher collective self-esteem than their non-victimised peers, clearly a novel finding worthy of further research. Findings suggested that, rather than running the risk of underreporting of socially undesirable behaviours, self-report methods provide a useful and valid means of measuring prevalence rates and internal states. Rather than underreporting aggressive behaviours, it is likely that respondents were being honest as they did not feel that these behaviours were, in fact, socially undesirable. The present sample reported bullying and victimisation prevalence rates that were comparatively high, despite using relatively conservative criteria, possibly due to an increased awareness of what constitutes bullying as a result of government and school anti-bullying policies and initiatives. The findings generally correspond with and build upon previous research. In addition, a number of the results are novel, providing numerous opportunities for future researchers to further explore and test the relationships between self-esteem, bullying, and victimisation.

The current study examined the development of responding to joint attention (RJA), a prelinguistic skill, in a sample of children prenatally cocaine exposed. The sample used was part of a larger population of children randomly assigned to three levels of intervention. The growth of RJA in the current sample was best characterized by two linear growth groups determined by a semi-parametric growth modeling program. Each trajectory group was differentially associated with three language outcomes. Gender, treatment group, and birthweight were three risk factors that influenced the likelihood of belonging to either growth cluster. RJA?s predictive significance in terms of concurrent and subsequent language was also established, accounting for the variance associated with contemporaneous measures of cognition. The findings (regarding the relationship between RJA and language) were consistent with previous research examining joint attention behaviors in other types of samples. Additionally, this study contributed uniquely to the body of research on joint attention by exploring the growth of RJA, a precursor of language, in a sample of children at risk for language impairment.

Den psykiska ohälsan bland unga kvinnor ökar i samhället idag.  Självskadebeteendet kan vara ett sätt för dem att lindra sin ångest. Tidigare forskning visar att sjuksköterskor upplever en vanmakt och osäkerhet inför denna patientgrupp. Syftet med denna studie är att, genom kvalitativ analys av fyra självbiografier, beskriva unga kvinnors upplevelser av självskadebeteende. Resultatet bygger på fyra huvudkategorier med vardera två subkategorier som illustreras och förtydligas med citat från författarna. Huvudkategorierna speglar fyra områden som har stor betydelse för utvecklingen av självskadebeteendet. Resultatet beskriver författarnas gemensamma erfarenheter av självförakt och utanförskap, samt deras olika uppväxtförhållanden och personligheter. Diskussionen betonar att vårdpersonalen bör närma sig lidandet bakom självskadebeteendet med förståelse och respekt, vilket kräver kunskap om patienter som skadar sig själva. / The mental unhealthiness amongst young women is increasing in society today. Self-harm behaviour can be a way for them to alleviate their anxiety. Previous research shows that nurses perceive powerlessness and uncertainty for this population. The purpose of this study is to describe the experiences of self-harm behaviour in young women through qualitative analysis of four autobiographies. The result is based on four major categories, each with two subcategories, illustrated and clarified with quotations from the authors. The major categories reflect four areas of key importance to the development of self-harm behaviour. The result describes the authors' common experience of self contempt and alienation, and their different growing conditions and personalities. The discussion emphasizes that health care providers should approach the suffering behind self-harm behaviour with understanding and respect, which requires knowledge of patients harming themselves.

The purpose of this study was to evaluate the effects of video self-modeling and behavior skills training to teach social skills to children with Asperger’s and high functioning autism. The targeted social skills were social initiations and social responses. The video self-modeling alone condition was implemented first using a video feedforward approach. A behavior skills training (BST) procedure was implemented following the video self-modeling alone condition for each participant. BST consisted of instructions, modeling, rehearsal, and feedback. The frequency of each target behavior was scored from videotapes using 10-second frequency within interval recording. After the video self-modeling was introduced, a mean increase was demonstrated in the target behaviors for 3 of the 4 participants. However, following the video self-modeling plus behavior skills training procedures, the social skills increased further for each participant. Follow up measures showed that the social interactions for each participant remained higher than baseline, however slightly lower than levels during BST+VSM.

Previous research has examined the effects of response card use at various grades levels including elementary, middle, high school, and community college. These studies provide convincing evidence that incorporating response cards into group instruction helps improve learning outcomes. However, the majority of these studies focused solely on learning outcomes, typically assessed through the administration of tests and/or quizzes. The present study examined the effects of response cards on learning, and expanded the research by assessing effects on disruptive student behavior and the quantity and quality of interactions between teachers and students. A second grade teacher and two students were exposed to response cards in an alternating treatments design. Results showed increased positive responding from both teachers and students during response card sessions. However, inappropriate student behavior and negative teacher comments also increased during response card classes. This study provides preliminary evidence that active responding strategies can increase the amount of positive interactions between teachers and students.

Prior work has shown important effects of the early life environment on development of adult stress response systems in both rats and humans. The present thesis is based on experiments that attempt to explore: 1) adolescent stress responding at hormonal and behavioural levels, and 2) the effects of repeated adolescent stressor exposure on adult stress responding (hormonal and behavioural) and levels of dopamine receptors expressed in prefrontal cortex, using both male and female rats. Defensive behaviours exhibited during stressor exposure and post-stress levels of circulating corticosterone were quantified as behavioural and hormonal measures of stress responding, respectively. In the first study, responses were compared among groups of adolescent rats exposed repeatedly to one of two different types of cat odour stressor stimuli (J-cloth coated in hair/dander or cat collar previously worn by a cat) or control stimuli, and long-term outcomes were examined in adulthood. Adolescent rats showed behavioural responses to both stressor stimuli, but behavioural inhibition was more consistent using repeated cat collar exposure, and this treatment resulted in long-term increases in anxiety-like behaviour in adulthood, whereas a stress-induced adolescent corticosterone elevation was observed only in the group that received exposure to the J-cloth stimuli. In the second study, adolescent and adult rats were compared directly using repeated exposure to the cat collar stressor or control stimuli. Adolescents were found to be more sensitive to the effects of the stressor stimuli, relative to adults. Finally, in the third study, repeated exposure to the J-cloth stressor or control stimuli was used, and stressor-exposed females showed elevated baseline corticosterone levels prior to the final exposure. Furthermore, stressor-exposed males and females showed lower levels of the D2 dopamine receptor in infralimbic and dorsopeduncular cortices of the prefrontal cortex in adulthood. In addition, these studies together provide evidence that sex differences in corticosterone levels emerge during the adolescent period. It may be concluded that adolescence should be considered a sensitive developmental timeframe for stress response programming.

Sidman's (2000) theory of stimulus equivalence states that all positive elements in a reinforcement contingency enter an equivalence class. The theory also states that if an element from an equivalence class conflicts with a programmed reinforcement contingency, the conflicting element will drop out of the equivalence class. Minster et al. (2006) found evidence suggesting that a conflicting element does not drop out of an equivalence class. In an effort to explain maintained accuracy on programmed reinforcement contingencies, the authors seem to suggest that participants will behave in accordance with a particular partitioning of the equivalence class which continues to include the conflicting element. This hypothesis seems to explain their data well, but their particular procedures are not a good test of the notion of "dropping out" due to the pre-establishment of equivalence classes before the conflicting member entered the class. The current experiment first developed unpartitioned equivalence classes and only later exposed participants to reinforcement contingencies that conflicted with pre-established equivalence classes. The results are consistent with the notion that a partition developed such that the conflicting element had dropped out of certain subclasses of the original equivalence class. The notion of a partitioning of an equivalence class seems to provide a fuller description of the phenomenon Sidman (1994, 2000) described as "dropping out" of an equivalence class.

The following studies examined the effectiveness and the efficiency of individual and small group equivalence-based instruction on English and math relations with elementary school children. The first experiment implemented a multiple-probe design across three typically developing third graders using an automated procedure to evaluate the stimulus equivalence paradigm (SEP) on establishing English and math equivalence classes. Since some researchers have proposed that covert behavior facilitates in the formation of equivalence classes (Horne & Lowe, 1996; Stromer, Mackay, & Remington, 1996), the second experiment examined the possible role of covert behavior, more specifically, a visual imagining strategy, on correct responding after remedial instructional sessions. To further extend SEP into more academic environments, the third experiment used an observational learning procedure to evaluate the formation of English and math symmetry relations as well as the formation of equivalence classes in a small group format. The emergence of topography-based responding was also assessed after instruction for all three experiments.
