Frontolimbic neural circuitry at 6 months predicts individual differences in joint attention at 9 months

Elucidating the neural basis of joint attention in infancy promises to yield important insights into the development of language and social cognition, and directly informs developmental models of autism. We describe a new method for evaluating responding to joint attention performance in infancy that highlights the 9‐ to 10‐month period as a time interval of maximal individual differences. We then demonstrate that fractional anisotropy in the right uncinate fasciculus, a white matter fiber bundle connecting the amygdala to the ventral‐medial prefrontal cortex and anterior temporal pole, measured in 6‐month‐olds predicts individual differences in responding to joint attention at 9 months of age. The white matter microstructure of the right uncinate was not related to receptive language ability at 9 months. These findings suggest that the development of core nonverbal social communication skills in infancy is largely supported by preceding developments within right lateralized frontotemporal brain systems.     

A Case Study Demonstrating Reduction of Aggressive Client Behaviors Using the Neuro-Occupation Model: Addressing Professional Burnout through Nonlinear Thinking

This single case study suggests that mental health practitioners adopt nonlinear modes of thinking within the neuro-occupation model to avoid professional burnout. Accordingly, the elimination of severely aggressive behavior of an institutionalized client was reviewed following an intervention using the model. Provided with new opportunities, the client self-extinguished aggressive interactions, reinstated social behaviors, and expanded occupations. Accepting clients as their own change agents limits our role to facilitators and reframes service delivery in mental health, which argues for comparison studies that measure reduced burnout in occupational therapists using the model.     

Splenium development and early spoken language in human infants

The association between developmental trajectories of language‐related white matter fiber pathways from 6 to 24 months of age and individual differences in language production at 24 months of age was investigated. The splenium of the corpus callosum, a fiber pathway projecting through the posterior hub of the default mode network to occipital visual areas, was examined as well as pathways implicated in language function in the mature brain, including the arcuate fasciculi, uncinate fasciculi, and inferior longitudinal fasciculi. The hypothesis that the development of neural circuitry supporting domain‐general orienting skills would relate to later language performance was tested in a large sample of typically developing infants. The present study included 77 infants with diffusion weighted MRI scans at 6, 12 and 24 months and language assessment at 24 months. The rate of change in splenium development varied significantly as a function of language production, such that children with greater change in fractional anisotropy (FA) from 6 to 24 months produced more words at 24 months. Contrary to findings from older children and adults, significant associations between language production and FA in the arcuate, uncinate, or left inferior longitudinal fasciculi were not observed. The current study highlights the importance of tracing brain development trajectories from infancy to fully elucidate emerging brain–behavior associations while also emphasizing the role of the splenium as a key node in the structural network that supports the acquisition of spoken language.     

Phallic narcissism, anal sadism, and oral discord: the case of Yukio Mishima, Part I

Thus far I have explored Mishima's traumatic childhood and the experiences leading him toward misogyny, phallic narcissism, and the drive to murder his own weakness and sexual vulnerability. Mishima suffered the extraordinary trauma of being separated from his parents and sequestered to the sickroom of a psychotic grandmother for the first twelve years of his life. Intense rage over abandonment and impingement engendered a disgust for femininity and the need to escape feminine messiness through homosexual pursuits. Mishima's entrenched feelings of shame and weakness gave rise to phallic narcissistic tendencies, as he idealized powerful men and eventually strove to become a powerful and beautiful male. In pursuing this erotic masculine image Mishima continued to fantasize about murdering his weak and shameful self-image, and commingled this sadistic impulse with fantasies of sexual merger with murdered love objects. Finally Mishima was the murderer erotically eradicating his sexual vulnerability as both subject and object. His suicide was a repetition of this erotic sadistic fantasy. In a further article I will continue the discussion by examining Mishima's fantasies of murdering beautiful and abandoning love objects. I will also address the complex nature of his ritual suicide as fantasy of rebirth, sexual merger, the murder of toxic introjects, and escape from death, decay, and regression to helpless infancy.
