A behavior genetic investigation of adolescent motherhood and offspring mental health problems

The present study examines the relations between adolescent motherhood and children's behavior, substance use, and internalizing problems in a sample of 1,368 children of 712 female twins from Australia. Adolescent motherhood remained significantly associated with all mental health problems, even when using a quasiexperimental design capable of controlling for genetic and environmental confounds. However, the relation between adolescent motherhood and offspring behavior problems and substance use was partially confounded by family background variables that influence both generations. The results are consistent with a causal relation between adolescent motherhood and offspring mental health problems, and they highlight the usefulness of behavior genetic designs when examining putative environmental risks for the development of psychopathology. The generalizability of these results to the United States, which has a higher adolescent birth rate, is discussed.     

The Significance of the Emergence of Language and Symbol in the Development of the Young Infant

In this paper I have suggested that the mother–child dyad is the foundation for integrity between the psychic self and the physical self, and the capacity of these to relate to the external environment. I have also argued that the development of language and symbol are creative agents in the development of consciousness in the young infant, and that the emergence of language and symbol are an expression of the opening of a potential space which allows differentiation from the mother and facilitates the infant’s ability to distinguish fantasy from fact and self from other.

Vestibular stimulation interferes with the dynamics of an internal representation of gravity

The remembered vanishing location of a moving target has been found to be displaced downward in the direction of gravity (representational gravity) and more so with increasing retention intervals, suggesting that the visual spatial updating recruits an internal model of gravity. Despite being consistently linked with gravity, few inquiries have been made about the role of vestibular information in these trends. Previous experiments with static tilting of observers’ bodies suggest that under conflicting cues between the idiotropic vector and vestibular signals, the dynamic drift in memory is reduced to a constant displacement along the body’s main axis. The present experiment aims to replicate and extend these outcomes while keeping the observers’ bodies unchanged in relation to physical gravity by varying the gravito-inertial acceleration using a short-radius centrifuge. Observers were shown, while accelerated to varying degrees, targets moving along several directions and were required to indicate the perceived vanishing location after a variable interval. Increases of the gravito-inertial force (up to 1.4G), orthogonal to the idiotropic vector, did not affect the direction of representational gravity, but significantly disrupted its time course. The role and functioning of an internal model of gravity for spatial perception and orientation are discussed in light of the results.     

Anticipatory modulation of precision grip force with variations in limb velocity of a curvilinear movement

The authors examined the relationship between peak velocity of a discrete horizontal elbow flexion movement in which the hand path was curvilinear and premovement modulation of precision grip force. The velocity of the movements of 7 participants was varied from maximal velocity to a velocity that required several seconds to reach a target. An object instrumented with force transducers for the forefinger and thumb measured precision grip force. There was a positively accelerating quadratic relationship between grip force change before movement and peak velocity of the ensuing limb movement. On some low-velocity trials, premovement grip force modulation reflected a net decrease. In contrast, high-velocity trials were preceded by net increases in grip force. Using cluster analysis, the authors classified grip forces in low-velocity movements as an empirically distinct set of entities from grip forces in high-velocity movements. The cluster of high-value grip forces suggested an anticipatory strategy that allowed participants a large safety margin in grip force to avoid object slip on movement initiation. The cluster of low-value grip forces at movement initiation suggested a second anticipatory strategy in which participants changed grip force very little, perhaps to increase the ability of proprioceptors in the hand to sense force changes. Those findings suggest that modulation of grip force before initiation of movements in which the hand path is curvilinear may be governed by two distinct velocity-dependent anticipatory strategies.     

The effects of concurrent task interference on category learning: evidence for multiple category learning systems

Participants learned simple and complex category structures under typical single-task conditions and when performing a simultaneous numerical Stroop task. In the simple categorization tasks, each set of contrasting categories was separated by a unidimensional explicit rule, whereas the complex tasks required integrating information from three stimulus dimensions and resulted in implicit rules that were difficult to verbalize. The concurrent Stroop task dramatically impaired learning of the simple explicit rules, but did not significantly delay learning of the complex implicit rules. These results support the hypothesis that category learning is mediated by multiple learning systems.     

An interpretation of Babette's Feast as a parable of trauma

In this paper I use the film Babette's Feast as a parable to portray the impasse that often arises out of the experience of complex trauma. The experience of such trauma invokes a crisis of reality. It overflows the boundaries of rational containment. There are no mechanisms with which to apprehend such an event, and consequently it cannot be comprehended; because it cannot be comprehended it cannot be processed. The film Babette's Feast encapsulates the predicament of the individual ensnared in the web of trauma. Although removed from the location and events of her trauma, Babette remains the resident of an austere and colourless environment, her gifts repressed, her brilliance unseen. Healing comes to Babette through her willingness to revisit her true self, a self that has been crushed under the weight of grief and trauma. This revisiting costs her all she has. Yet, it is in this revisiting that she not only frees herself from the austerity of her environment but also engenders purpose and hope within the community who have taken her in. The dissonance of her life is paralleled by the dissonance of the life of the community in which she lives; it is the harmonizing of these dissonances which cannot be spoken that finally gives articulation to the incoherence of Babette's trauma.     

Evaluating Supervision Models in Functional Family Therapy: Does Adding Observation Enhance Outcomes?

This study examined the effects of observation‐based supervision Building Outcomes with Observation‐Based Supervision of Therapy (BOOST therapists = 26, families = 105), versus supervision as usual (SAU therapists = 21, families = 59) on (a) youth externalizing behavior problems and (b) the moderating effects of changes in family functioning on youth externalizing behaviors for adolescents receiving Functional Family Therapy (FFT). Exploratory analyses examined the impact of supervision conditions on youth internalizing problems. In 8 community agencies, experienced FFT therapists (M = 1.4 years) received either BOOST or SAU supervision in a quasi‐experimental design. Male (59%) or female (41%) adolescents were referred for the treatment of behavior problems (e.g., delinquency, substance use). Clients were Hispanic (62%), African American (19%), Non‐Hispanic White (12%), or Other (7%) ethnic/racial origins. Therapists (female, 77%) were Hispanic 45%, African American (19%), White Non‐Hispanic (30%), or other (4%) ethnic/racial backgrounds. Analyses controlled for the presence or absence of clinically elevated symptoms on outcome variables. Clinical outcomes were measured at baseline, 5 months, and 12 months after treatment initiation. Clients with externalizing behavior above clinical thresholds had significantly greater reductions in problem behaviors in the BOOST versus the SAU conditions. Clients below thresholds did not respond differentially to conditions. Supervisors in BOOST had more experience with the FFT model; as such, the observed results may be a result of supervisor experience. The BOOST supervision was associated with improved outcomes on problem behaviors that were above clinical thresholds. The findings demonstrate the importance of addressing client case mix in implementation studies in natural environments.     

Whose Church? Which Unity? That We May Be One: Practicing Unity in a Divided Church,Gary B. Agee,Eerdmans, 2022 (ISBN 978-0-8028-8186-1), xviii + 150 pp., pb $19.99 Winsome Conviction: Disagreeing Without Dividing the Church,Tim Muehlhoff and Richard Langer,InterVarsity Press, 2020 (ISBN 978-0-8380-4799-0), x + 214 pp., pb $17

These two recent books each offer guidance to Christians in the United States on pursuing unity in the midst of social, moral, political, and theological divisions. They offer two distinct approaches: one relying mainly on relevant academic research and the other drawing mostly on a pastoral appeal. They also target different audiences: one an explicitly theologically conservative evangelical ‘church’, the other a ‘church’ including all professed Christians. This review argues that both have different strengths. While Agee's approach is ultimately more promising for addressing the underlying causes of disunity among Christians, Muehlhoff and Langer offer well-founded tactics for mutual understanding within a more limited group of Christians.
