Signature tunes in mothers' speech to infants

The purpose of the present investigation was to determine whether mothers use discernible tunes (i.e., specific interval sequences) in their speech to infants and whether such tunes are individually distinctive. Mothers were recorded speaking with their infants on two occasions separated by 1 week or more. Examination of the tunes of each mother revealed discernible tunes and frequent repetitions of tunes within and across sessions. Comparisons of utterances with the most common pitch contour (i.e., rising), both within and across mothers, revealed interval patterns that were individually distinctive, or unique. The findings confirm the prominence of tunes and the presence of signature tunes in maternal speech to infants.     

A systematic examination of different parameters of presession exposure to tangible stimuli that maintain problem behavior

We examined the effects of three different presession conditions on tangibly maintained problem behavior for 2 students with autism, using individual-participant multielement designs. First, an analogue functional analysis demonstrated that problem behavior was maintained by access to tangible items. Next, topographies of item rejection were identified. Finally, students were exposed to (a) brief access, (b) no access, and (c) satiation to the tangible items prior to tangible sessions. The results demonstrated high levels of problem behavior following the brief-access and no-access presession conditions and low levels of problem behavior following the satiation condition. The findings are discussed in the context of how satiation might best be defined for these sorts of evaluations.     

Oculomotor and manual indexes of incidental and intentional spatial sequence learning during middle childhood and adolescence

The goal of this study was to examine incidental and intentional spatial sequence learning during middle childhood and adolescence. We tested four age groups (8-10 years, 11-13 years, 14-17 years, and young adults [18+ years]) on a serial reaction time task and used manual and oculomotor measures to examine incidental sequence learning. Participants were also administered a trial block in which they were explicitly instructed to learn a sequence. Replicating our previous study with adults, oculomotor anticipations and response times showed learning effects similar to those in the manual modality. There were few age-related differences in the sequence learning indexes during incidental learning, but intentional learning yielded differences on all indexes. Results indicate that the search for regularities and the ability to learn a sequence rapidly under incidental conditions are mature by 8 to 10 years of age. In contrast, the ability to learn a sequence intentionally, which requires cognitive resources and strategies, continues to develop through adolescence.     

Length of Time to Resolve Criminal Charges of Child Sexual Abuse: A Three-County Case Study

The present study sought to examine the court culture of three Oregon counties and their timelines for resolving felony child sexual abuse cases. Specifically, we examined (a) case outcomes, churning (i.e., the extent to which four court events were rescheduled), the length of time to reach a criminal case resolution, and how this length of time compared to that for felonies generally; (b) whether mandatory minimum sentences affected resolution timeliness; and (c) key stakeholders’ perceptions about their local court culture. Data included retrospective case-file abstraction (N = 532) on all felony child sex crimes for a 2-year period and interviews with legal professionals (N = 23). Across all three counties, a minority of child sexual abuse cases (18% to 47%) were resolved within the target timeframe of 4 months. In contrast, most felonies (65% to 77%) were resolved within this timeframe. The rescheduling of trials and the requirement of mandatory minimum sentences for some felony child sexual abuse crimes increased the time until case resolution. Results suggest that court cultures that are hierarchical and cooperative may lead to longer case resolution times than court cultures that are self-managing or autonomous. Implications of these results and other results are discussed. Copyright © 2015 John Wiley & Sons, Ltd.     

Parent‐implemented brief functional analysis and treatment with coaching via telehealth

We evaluated the use of parent‐implemented brief functional analyses in the home with coaching delivered via telehealth. Parents of 7 children with autism conducted functional analyses of their child's challenging behavior. For 4 participants, the brief functional analysis provided information regarding the function of the child's challenging behavior. A full functional analysis indicated a social function for 1 participant. The brief functional analysis yielded false positive results and subsequent assessment indicated an automatic function for another participant. The final participant did not engage in sufficient rates of challenging behavior to provide information regarding the function of the child's challenging behavior. Treatment evaluations occurred with 4 participants; these evaluations provided support for the results of the functional analysis. Together with previous research, the results indicate that parent‐implemented brief functional analyses, followed by additional assessment as needed, may be an effective method for assessing and treating challenging behavior via telehealth.     

Family as a source of support under stress: Benefits of greater breadth of family inclusion

Family has profound meaning and represents the most important ingroup for most people, yet, we know very little about how lay perceptions of family affect well-being. In the current work, we examined how lay theories about breadth of family inclusion (i.e., including a broader variety of entities in one’s definition of family) were related to family experiences and to well-being. In Study 1, we found that lay theories about family as including a wider variety of entities (i.e., greater breadth of inclusion) predicted more positive family evaluations, more positive qualities, and greater family importance. In Study 2, we found that greater breadth of family inclusion was associated with greater resilience in the face of stress. Finally, in Study 3 we used an experimental manipulation of breadth of family inclusion, establishing that broader views of family produced greater social needs fulfillment. Implications for the role of ingroup memberships and identities in promoting well-being are discussed.     

Taking the Red Pill: Using The Matrix to Explore Transgender Identity Development

This article presents a plot analysis of The Matrix and comparisons to a transgender identity development model. Major scenes throughout the movie are discussed through the lens of Devor’s transgender identity development model. The main character’s evolution from Mr. Anderson to Neo is presented, as well as how his experiences align with multiple stages in transgender identity development. Stages of transgender identity development are discussed and emphasized, including identity confusion, discovery of transgenderism, identity acceptance, transition, and transgender pride. These stages and others are discussed and related to uses in counseling sessions with transgender individuals and their family members.     

The development of gyrification in childhood and adolescence

Gyrification is the process by which the brain undergoes changes in surface morphology to create sulcal and gyral regions. The period of greatest development of brain gyrification is during the third trimester of pregnancy, a period of time in which the brain undergoes considerable growth. Little is known about changes in gyrification during childhood and adolescence, although considering the changes in gray matter volume and thickness during this time period, it is conceivable that alterations in the brain surface morphology could also occur during this period of development. The formation of gyri and sulci in the brain allows for compact wiring that promotes and enhances efficient neural processing. If cerebral function and form are linked through the organization of neural connectivity, then alterations in neural connectivity, i.e., synaptic pruning, may also alter the gyral and sulcal patterns of the brain. This paper reviews developmental theories of gyrification, computational techniques for measuring gyrification, and the potential interaction between gyrification and neuronal connectivity. We also present recent findings involving alterations in gyrification during childhood and adolescence.     

Developmental changes in dopamine neurotransmission in adolescence: Behavioral implications and issues in assessment

Adolescence is characterized by increased risk-taking, novelty-seeking, and locomotor activity, all of which suggest a heightened appetitive drive. The neurotransmitter dopamine is typically associated with behavioral activation and heightened forms of appetitive behavior in mammalian species, and this pattern of activation has been described in terms of a neurobehavioral system that underlies incentive-motivated behavior. Adolescence may be a time of elevated activity within this system. This review provides a summary of changes within cortical and subcortical dopaminergic systems that may account for changes in cognition and affect that characterize adolescent behavior. Because there is a dearth of information regarding neurochemical changes in human adolescents, models for assessing links between neurochemical activity and behavior in human adolescents will be described using molecular genetic techniques. Furthermore, we will suggest how these techniques can be combined with other methods such as pharmacology to measure the impact of dopamine activity on behavior and how this relation changes through the lifespan.     

PROBLEM BEHAVIOR DURING PREFERENCE ASSESSMENTS: AN EMPIRICAL ANALYSIS AND PRACTICAL RECOMMENDATIONS

Preferences of 2 children with developmental disabilities, whose functional analyses indicated that their problem behavior was maintained by access to tangible items, were assessed using three formats (i.e., paired stimulus [PS], multiple‐stimulus without replacement [MSWO], and free operant [FO]). The experimenter administered each format five times and compared levels of problem behavior across formats in a multielement design. Both participants exhibited problem behavior in PS and MSWO formats but not in the FO format. Results are discussed in terms of recommendations for practitioners.
