The effect of communication deficits on anxiety symptoms in infants and toddlers with autism spectrum disorders

Autism spectrum disorders (ASDs) are life-long developmental disorders characterized by impairments in the development of reciprocal social and communication skills, abnormal language development, and a restricted repertoire of behaviors and interests. While it has been known for some time that children with ASD can evince elevated rates of anxiety symptoms, little research has been conducted on whether deficits in communication skills affect the range of anxiety symptoms in infants and toddlers with ASD. This study represents a first attempt to determine whether deficits in communication skills have an effect on the expression of anxiety in infants and toddlers with autistic disorder and pervasive developmental disorder-not otherwise specified. Seven hundred thirty-five infants were evaluated with respect to the nature and extent of anxiety symptoms and developmental functioning. Both receptive and expressive communication skills appeared to play a significant role in the manifestation of anxiety symptoms.     

NONCONTINGENT REINFORCEMENT: A FURTHER EXAMINATION OF SCHEDULE EFFECTS DURING TREATMENT

We conducted 2 studies to determine whether dense and thin NCR schedules exert different influences over behavior and whether these influences change as dense schedules are thinned. In Study 1, we observed that thin as well as dense NCR schedules effectively decreased problem behavior exhibited by 3 individuals. In Study 2, we compared the effects of 2 NCR schedules in multielement designs, one with and the other without an extinction (EXT) component, while both schedules were thinned. Problem behavior remained low as the NCR schedule with EXT was thinned, but either (a) did not decrease initially or (b) subsequently increased as the NCR schedule without EXT was thinned. These results suggest that dense schedules of NCR decrease behavior by altering its motivating operation but that extinction occurs as the NCR schedule is thinned. The benefits and limitations of using dense or thin NCR schedules are discussed.     

How images may or may not represent flowers: picture–object correspondence in bumblebees (Bombus impatiens)?

Studies of bee cognition frequently use two-dimensional stimuli referred to as floral patterns, and yet how bees perceive pictorial representations is not known. An investigation of bumblebee (Bombus impatiens) picture–object correspondence was undertaken according to the theory of Fagot et al. (Picture perception in animals. Psychology Press Ltd, East Sussex, pp 295–320, 2000) that pictures and objects may be confused, perceived as independent or equivalent. In three experiments, bumblebees were given discrimination training and unrewarded testing in a radial maze. In the first experiment, preferences between artificial flowers and photographs of those flowers revealed a significant learned preference for the stimulus rewarded during training: no confusion following training. In the second experiment, bees did transfer learning from artificial flowers to photographs: some commonality between an object and photograph was perceived. In the third experiment, bees spontaneously generalized a learned preference for one artificial flower to its silhouette, but only for one of two flowers used in training. No generalization was obtained to drawn images. Some transfer between image and object is exhibited, likely by low-level feature matching, but transfer is poor with degraded images, cautioning against extrapolation of picture-based responding to natural correspondents. Despite evidence that bees exhibit some transfer while retaining discrimination, it is likely that the observed response is due to generalization more akin to confusion than true equivalence. Furthermore, although 2D patterning cues (line, edge and shade) provide discriminable cues for bees between 2D stimuli, it is not here supported that such features are perceived as equivalent to the intended floral structures.     

The Bhakta and the Sage: An Intertextual Dialogue

Comparing the Bhagavad Gītā and the Buddhist essay “Prajñā is Not-knowing” (Panruo Wuzhi 般若無知) yields interesting insights. The texts have similar dialogical structures and discuss complex philosophical matters. Rhetorically, both texts weave together quotations and allusions from other texts, make liberal use of paradox, and have decidedly spiritual intentions. Their differences, though, remain striking. They emerge from distinct circumstances and their original languages (Sanskrit, Chinese) differ markedly. Stylistically, “Prajñā” is more intellectual and less devotional, espousing a distinctly “this worldly” ideal; by contrast, the Gītā is more dramatic. While espousing “this worldly” ideals, the Gītā is more inclusive and thus more accessible to a broad audience; on the contrary, “Prajñā” has a subtler effect, its “dark” qualities appealing to a more select group. Therefore, while these texts are not “the same,” reading across their convergences and divergences can lead to a deeper understanding of mysticism and cross-cultural spirituality.     

REARRANGING NATURALLY OCCURRING CONTINGENCIES TO INCREASE DESIRABLE BEHAVIOR IN A TODDLER CLASSROOM

Toddlers often display problem behavior during transitions. We rearranged naturally occurring events in a toddler classroom to promote more desirable classroom behavior during transitions to meals. In the intervention condition, teachers transitioned each child to meals only when that child was seated on a play mat (a requisite for engagement in teacher‐led play activities). In the reversal condition, teachers selected each child to transition when that child was by the barrier to the meal area (a practice commonly observed under natural conditions). The intervention increased the mean percentage of intervals when children were on the play mat and decreased the percentage of intervals when children were by the barrier. Individual child data show positive outcomes for five of six children. Results are discussed in terms of the positive effects of small manipulations to existing contingencies on classroom behavior as well as their potential influence on the adoptability of classroom interventions.

Conflict,metacognition, and analytic thinking

One hundred and three participants solved conflict and non-conflict versions of four reasoning tasks using a two-response procedure: a base rate task, a causal reasoning task, a denominator neglect task, and a categorical syllogisms task. Participants were asked to give their first, intuitive answer, to make a Feeling of Rightness (FOR) judgment, and then were given as much time as needed to rethink their answer. They also completed a standardized measure of IQ and the actively open-minded thinking questionnaire. The FORs of both high- and low-capacity reasoners were responsive to conflict, such that FORs were lower for conflict relative to non-conflict problems. Consistent with the quantity hypothesis, high-capacity reasoners made a greater distinction between conflict and non-conflict items on measures of Type 2 thinking, namely, rethinking time and probability of changing answers. In contrast to the quality hypothesis, however, this rethinking time did not advantage the ability of the high-capacity group to produce normative answers, except for the base rate task. Indeed, we observed that the correlation between capacity and the probability of normative answers emerged at the initial response, rather than after rethinking.     

In Dogs We Trust? Intersubjectivity,Response‐Able Relations,and the Making of Mine Detector Dogs

The utility of the dog as a mine detector has divided the mine clearance community since dogs were first used for this purpose during the Second World War. This paper adopts a historical perspective to investigate how, why, and to what consequence, the use of minedogs remains contested despite decades of research into their abilities. It explores the changing factors that have made it possible to think that dogs could, or could not, serve as reliable detectors of landmines over time. Beginning with an analysis of the wartime context that shaped the creation of minedogs, the paper then examines two contemporaneous investigations undertaken in the 1950s. The first, a British investigation pursued by the anatomist Solly Zuckerman, concluded that dogs could never be the mine hunter's best friend. The second, an American study led by the parapsychologist J. B. Rhine, suggested dogs were potentially useful for mine clearance. Drawing on literature from science studies and the emerging subdiscipline of “animal studies,” it is argued that cross‐species intersubjectivity played a significant role in determining these different positions. The conceptual landscapes of Zuckerman and Rhine's disciplinary backgrounds are shown to have produced distinct approaches to managing cross‐species relations, thus explaining how diverse opinions on minedog can coexist. In conclusion, it is shown that the way one structures relationships between humans and animals has profound impact on the knowledge and labor subsequently produced, a process that cannot be separated from ethical consequence.     

A Pilot Randomized Trial of Community-Based Parent Training for Immigrant Latina Mothers

This paper reports on the development and piloting of the Madres a Madres (Mothers to Mothers) program, a new, community-based parent training program designed for immigrant Latina mothers and their children. Promotoras, or female community health workers of Latina background, delivered the program in a home visitation format. A total of 194 mothers and 194 focal children (87 male, 107 female) ages 7–12 were randomized to the intervention (113 mother–child dyads) or wait-list control condition (81 mother–child dyads) over the study period. Outcomes of interest were mother-reported parenting skills, broad family functioning, and child externalizing and internalizing behaviors. Data collection occurred at pretest, 3-month posttest, and 9-month follow-up periods. Multilevel growth models revealed increases in intervention mothers’ reported parenting skills, family support, and family organization, and reductions in child internalizing behavior from pretest to follow-up, relative to the control condition. Outcomes did not vary by focal child age, gender, nativity status, or mother acculturative status (years in the United States). Findings are discussed in the context of future directions for research on the Madres a Madres program and on the implementation and dissemination of empirically-supported parent training practices to culturally diverse families.     

Signature Limits in Mindreading Systems

Recent evidence that young children seem to both understand false belief in one sense, but not in another, has led to two‐systems theorizing about mindreading. By analyzing the most detailed two‐systems approach in studying social cognition—the theory of mindreading defended by Ian Apperly and Stephen Butterfill—I argue that that even when dutifully constructed, two‐systems approaches in social cognition struggle to adequately define the mindreading systems in terms of signature processing limits, an issue that becomes most apparent when investigating mindreading in infancy. I end the article by developing several challenges that face any two‐systems account of mindreading.     

Early Childhood Mental Health Consultation: Promoting Change in the Quality of Teacher–Child Interactions

The goal of this study was to examine the relationship between characteristics of early childhood mental health consultation (ECMHC) and changes in the quality of teacher–child interactions. One hundred forty‐one early childhood teachers, serving 3‐ to 5‐year‐olds in publically funded early education programs in the state of Arkansas, participated in this study. All childcare sites and preschool programs participating in the study received ECMHC through the Arkansas Early Childhood Mental Health Consultation Project over a period of 3 years. Findings from this study suggest that teachers exposed to ECMHC through their employment at one of the project sites made significant gains toward high‐quality teacher–child interactions relative to their initial levels of quality. In particular, delivery aspects of ECMHC and teachers’ experiences of ECMHC predicted change in quality of teacher–child interactions. Findings suggest that ECMHC may be a promising professional development intervention for teachers in early childhood settings and that specific characteristics of consultation may be particularly influential in impacting change in those settings.
