Variability in Adaptive Behavior in Autism: Evidence for the Importance of Family History

Adaptive behavior in autism is highly variable and strongly related to prognosis. This study explored family history as a potential source of variability in adaptive behavior in autism. Participants included 77 individuals (mean age = 18) with average or better intellectual ability and autism. Parents completed the Family History Interview about the presence of broader autism phenotype symptoms and major psychiatric disorders in first degree relatives. Adaptive behavior was assessed via the Vineland Adaptive Behavior Scales (VABS). Based on family history variables, age, and intelligence quotient (IQ), 87% of participants were correctly classified as having impaired or average VABS scores. Family history of depression and shyness accounted for the most variance in VABS scores, and they had the greatest influence on VABS Socialization scores in particular. Possible underlying mechanisms include genetics, psychosocial factors, and social resources. This study provides initial evidence of the importance of family history to adaptive behavior in autism and has implications for genetics and treatment.

Influence of aesthetic perception on visual event-related potentials

The aim of the study was to assess the effects of visual aesthetic perception on event-related potentials (ERPs). Eight subjects assigned an aesthetic judgment (beautiful, neutral, or ugly) and a 10-step beauty estimation to the target stimuli, consisting of famous artistic pictures and geometric shapes. In a further task, the subjects performed a motor response to the previously judged pictures and geometric shapes. ERPs were recorded through 54 scalp electrodes during both tasks. The P3b amplitude was increased during the categorization of the geometric shapes compared to the artistic figures and during the vision of the beautiful targets preceding the motor response. The categorization of the aesthetic qualities of geometrical shapes seems to induce a higher level of attention, while a higher arousal variation was elicited by the recognition of beauty, in any form that was presented.     

Effects of a Dependent Group-Oriented Contingency on Middle School Physical Education Students’ Fair Play Behaviors

This study investigated the effects of a dependent group-oriented contingency on the supportive and non-supportive fair play behaviors of 6th grade students engaged in volleyball games as part of their physical education instruction. Six students, one male and one female per class, from three classes, identified as demonstrating low incidences of supportive behaviors during volleyball games, were participants in this study. A multiple baseline across classes design was used to examine the data. During baseline few incidences of non-supportive behaviors occurred among all six students. However, the participants seldom displayed supportive behaviors during games (i.e., encouraged each other). Following the introduction of the dependent group contingency, supportive behaviors for all participants increased. Follow-up data, collected in an alternative setting, indicated variable maintenance. The results are discussed in the context of group contingencies and social behaviors in sports.     

If you say thee uh you are describing something hard: the on-line attribution of disfluency during reference comprehension

Eye-tracking and gating experiments examined reference comprehension with fluent (Click on the red. . .) and disfluent (Click on [pause] thee uh red . . .) instructions while listeners viewed displays with 2 familiar (e.g., ice cream cones) and 2 unfamiliar objects (e.g., squiggly shapes). Disfluent instructions made unfamiliar objects more expected, which influenced listeners' on-line hypotheses from the onset of the color word. The unfamiliarity bias was sharply reduced by instructions that the speaker had object agnosia, and thus difficulty naming familiar objects (Experiment 2), but was not affected by intermittent sources of speaker distraction (beeps and construction noises; Experiments 3). The authors conclude that listeners can make situation-specific inferences about likely sources of disfluency, but there are some limitations to these attributions.     

Touched by suicide: bridging the perspectives of survivors and clinicians

This article is a revised version of an invited plenary address given at the 39th Annual Conference of the American Association of Suicidology. The authors, a psychiatrist and a writer survivor, outline and summarize the different ways in which professionals and survivors come to an understanding of suicide. They explain how each group often exists independently and separate from the other--by cognitive and emotional dissonance, by private language, by psychological defenses and miscommunication--and call for dialog. They argue that both perspectives are essential to advance the science of suicidology and to give hope and meaning to those bereaved by suicide.     

Hurricane Evacuation Expectations and Actual Behavior in Hurricane Lili1

This study compared respondents' hurricane evacuation expectations with their actual behavior 2 years later during Hurricane Lili. Respondents were found to have accurate expectations about their information sources, evacuation transportation modes, number of vehicles taken, and evacuation shelter types. They also had generally accurate expectations about the time it would take them to implement some, but not all, evacuation preparation tasks. These results extend contemporary attitude–behavior models by demonstrating a significant degree of correspondence between behavioral expectations and much later behavior under quite stressful conditions and suggest emergency planners can use many, but not all, aspects of coastal residents' evacuation expectations as a satisfactory basis for evacuation planning.     

Effects of trophic poisoning with methylmercury on the appetitive elements of the agonistic sequence in fighting-fish (Betta splendens)

The aggressive display in Betta splendens is particularly prominent, and vital to its adaptation to the environment. Methylmercury is an organic variation of Hg that presents particularly pronounced neuro-behavioral effects. The present experiments aim to test the effect of acute and chronic poisoning with methylmercury on the display in Bettas. The animals were poisoned by trophic means in both experiments (16 ug/kg in acute poisoning; 16 ug/kg/day for chronic poisoning), and tested in agonistic pairs. The total frequency of the display was recorded, analyzing the topography of the agonistic response. The methylmercury seems to present a dose- and detoxification-dependent effect on these responses, with a more pronounced effect on motivity in acute poisoning and on emotionality in the chronic poisoning. It is possible that this effect could be mediated by alteration in the mono-amino-oxidase systems.     

The theory of thinking and the capacity to mentalize: a comparison of Fonagy's and Bion's models

This paper presents a comparison of two psychoanalytic models of how human beings learn to use their mental capacities to know meaningfully about the world. The first, Fonagy's model of mentalization, is concerned with the development of a self capable of reflecting upon its own and others' mental states, based on feelings, thoughts, intentions, and desires. The other, Bion's model of thinking, is about the way thoughts are dealt with by babies, facilitating the construction of a thinking apparatus within a framework of primitive ways of communication between mother and baby. The theories are compared along three axes: (a) an axis of the theoretical and philosophical backgrounds of the models; (b) an axis of the kind of evidence that supports them; and (c) the third axis of the technical implications of the ideas of each model. It is concluded that, although the models belong to different theoretical and epistemological traditions and are supported by different sorts of evidence, they may be located along the same developmental line using an intersubjective framework that maintains tension between the intersubjective and the intrapsychic domains of the mind.     

Improving self‐regulated learning of preschool children: Evaluation of training for kindergarten teachers

Background In the context of lifelong learning, self‐regulated learning is an important competence. Children between 4 and 6 years of age are at a crucial step in their life to develop self‐regulatory competence. That is why their kindergarten teachers play an important role as instructors as well as role models. Aim This study tested the effects of self‐regulation training for kindergarten teachers concerning their own self‐regulation and methods to foster self‐regulation in children at preschool age whom they were teaching. Sample In this study, 35 German kindergarten teachers and 97 children participated. All adult participants were graduated kindergarten teachers. Method The kindergarten teachers were tested with a questionnaire 2 weeks before and after the training. At the same time, the preschoolers were interviewed. A waiting control group design was applied. Results and conclusions The results obtained by means of analyses of variance show that the self‐regulation of the kindergarten teachers as well as the self‐regulated learning of preschoolers whose kindergarten teachers took part in the training improved significantly. The results indicate that it is possible to improve self‐regulated learning of preschool children by a training programme for kindergarten teachers.
