Visual experiences during letter production contribute to the development of the neural systems supporting letter perception

Letter production through handwriting creates visual experiences that may be important for the development of visual letter perception. We sought to better understand the neural responses to different visual percepts created during handwriting at different levels of experience. Three groups of participants, younger children, older children, and adults, ranging in age from 4.5 to 22 years old, were presented with dynamic and static presentations of their own handwritten letters, static presentations of an age‐matched control's handwritten letters, and typeface letters during fMRI. First, data from each group were analyzed through a series of contrasts designed to highlight neural systems that were most sensitive to each visual experience in each age group. We found that younger children recruited ventral‐temporal cortex during perception and this response was associated with the variability present in handwritten forms. Older children and adults also recruited ventral‐temporal cortex; this response, however, was significant for typed letter forms but not variability. The adult response to typed letters was more distributed than in the children, including ventral‐temporal, parietal, and frontal motor cortices. The adult response was also significant for one's own handwritten letters in left parietal cortex. Second, we compared responses among age groups. Compared to older children, younger children demonstrated a greater fusiform response associated with handwritten form variability. When compared to adults, younger children demonstrated a greater response to this variability in left parietal cortex. Our results suggest that the visual perception of the variability present in handwritten forms that occurs during handwriting may contribute to developmental changes in the neural systems that support letter perception.     

The symbol in the body: the un-doing of a dissociation through Embodied Active Imagination in Jungian analysis

Jung understood dissociation as a natural state of the psyche, capable of turning defensive through development. Based on this premise, and its conception on the equivalence between psyche and matter, the present work describes the un-doing of a dissociation expressed through a chronic enterocolitis disorder. When the symbol remains closer to the body and its most instinctive manifestations, we need to descend to that level in order to let the vertical axis connection be gradually restored through the therapeutic relationship – the horizontal axis. In other words, this un-doing requires that patient and analyst follow the unconscious path proposed by symbolic expressions that gradually emerge through the patient’s body and active imagination. Movement is our most primitive and fundamental experience. Many authors (Stern, Panksepp, Gallese) have agreed that, in addition to being first in terms of development, movement continues to have primacy over any other experience throughout life. This means that emotions, bodily concepts and, later, speech, evolve from a somatic basis. In the light of such neuroscientific findings, Jung’s vision of the correspondence of psyche and matter will be revisited in order to portray how the analytic bond provides a context for the re-establishment of the linking/creative function of the archetype, and allows the restoring of the ego-Self axis connection by including non-verbal approaches, such as body-based active imagination, also known as Authentic Movement. Authentic Movement is an amplification of Jung’s active imagination method that enables a dialogue between the ego and the diverse configurations of the unconscious. When such dialogue is grounded in the body, there is an easier access to the affective dimension stored in implicit memory. That which was relived through the body can gradually be remembered, and affects hitherto rejected, find other symbolic ways of being expressed and contained in the analytic vas.     

Barriers and Facilitators to Implementing Attachment-based Family Therapy into a Child Welfare Setting: A Qualitative Process Evaluation

Child welfare systems (CWSs) worldwide show increased interest in adopting empirically informed clinical strategies to increase treatment effectiveness. Many empirically supported treatments (ESTs) exist, but little is known about EST implementation barriers and facilitators in CWS. This study explored CWS providers’ experiences of implementing attachment-based family therapy (ABFT) in home-based services of the Flemish CWS (in Belgium). Sixteen CWS providers (twelve counselors and four supervisors) involved in three home-based services were interviewed. The Consolidated Framework for Implementation Research (CFIR) was used to guide collection, coding, and analysis of interview data. Findings revealed that implementation success was related to ABFT's fit with the CWS's mission, philosophy, and existing practices. CWS providers’ belief in the compatibility between ABFT and CWS increased investment in implementation efforts and persistence to overcome challenges and setbacks. Some barriers pertained to the learning of ABFT and some barriers pertained to systems level challenges such as lack of leadership and support, poor coordination with referral sources and other youth care partners, and lack of policy support. For successful expansion of ESTs into CWS settings, various barriers at multiple systemic levels need to be addressed.     

Parental influence on children's self-estimated agressiveness

Parental influence on children's self-estimated aggressivences was measured with inventories. One hundred seventy-four adolescents (85 girls and 89 boys; mean age 13.6 years, SD 0.7) from a suburban school, known as prone to problems of aggression, served as subjects. The dependent variable aggresive personality was measured with the Buss-Durkee Hostility Inventory [J consult Psychol 21:343, 1974]. Parental influence was measured with scales specifically developed for the present research. the subjects estimated: 1) their emotional relation to each parent; and 2) their perception of how their parents a and b) behave when angry c) at home and d) with their peers. The results revealed clearly gender-specific efects: mothers and fathers affected sons and daughters differently. According to LISREL analyse, mother had a clearly stronger impact on sons, while fathers had a slightly stronger effect on daughters. In the case of fathers, hiting and alcohol abuse were, in addition to a negative emotional relationship, strong predictors of daughter's aggresivencess. However, aggressive fathers tended in general to get a counterreaction with their sons, leading to low aggressiveness with the same type of behavior in their case. Typical maternal predictors of children's aggressivencess were shouting and a negative emotional relationship. In the case of daughters, the former was a more important predictor than the latter, but in the case of sons, it was the other way around. Modeling effects were revealed: subjects imitated their parents' styles of behavior in anger, however, with different patterns at home and with peers. The results may be interpreted as support for both the cognitive learning and the frustration-aggression hypotheses as sources for aggressive behavior. © 1992 Wiley-Liss, Inc.     

Auditory verb perception recruits motor systems in the developing brain: an fMRI investigation

This study investigated neural activation patterns during verb processing in children, using fMRI (functional Magnetic Resonance Imaging). Preschool children (aged 4–6) passively listened to lists of verbs and adjectives while neural activation was measured. Findings indicated that verbs were processed differently than adjectives, as the verbs recruited motor systems in the frontal cortex during auditory perception, but the adjectives did not. Further evidence suggested that different types of verbs activated different regions in the motor cortex. The results demonstrate that the motor system is recruited during verb perception in the developing brain, reflecting the embodied nature of language learning and processing.     

When knowing can replace seeing in audiovisual integration of actions

The ability to predict the effects of actions is necessary to behave properly in our physical and social world. Here, we describe how the ability to predict the consequence of complex gestures can change the way we integrate sight and sound when relevant visual information is missing. Six drummers and six novices were asked to judge audiovisual synchrony for drumming point-light displays where the visual information was manipulated to eliminate or include the drumstick–drumhead impact point. In the condition with only the arm information novices were unable to detect asynchrony whereas drummers were able to. Additionally, in the conditions that included the impact point drummers perceived the best alignment when the sight preceded the sound, while in the arm only condition they perceived the best alignment when the sound occurred together with or preceded the sight, as it would be expected if they were predicting the beat occurrence. Taken together these findings suggest that humans can acquire, through practice, internal models of action which can be used to replace missing information when integrating multisensory signals from the environment.     

Rejection sensitivity and disruption of attention by social threat cues

Two studies tested the hypothesis that Rejection Sensitivity (RS) increases vulnerability to disruption of attention by social threat cues, as would be consistent with prior evidence that it motivates individuals to prioritize detecting and managing potential rejection at a cost to other personal and interpersonal goals. In Study 1, RS predicted disruption of ongoing goal-directed attention by social threat but not negative words in an Emotional Stroop task. In Study 2, RS predicted attentional avoidance of threatening but not pleasant faces in a Visual Probe task. Threat-avoidant attention was also associated with features of borderline personality disorder. This research extends understanding of processes by which RS contributes to a self-perpetuating cycle of interpersonal problems and distress.     

Immunotoxic cholinergic lesions in the basal forebrain reverse the effects of entorhinal cortex lesions on conditioned odor aversion in the rat

Conditioned odor aversion (COA) corresponds to the avoidance of an odorized-tasteless solution (conditioned stimulus, CS) previously paired with toxicosis. COA occurs only when the interstimulus interval (ISI) is kept short, suggesting that the memory trace of the odor is subject to rapid decay. Previous experiments have shown that the entorhinal cortex (EC) is involved in the acquisition of COA, since lesion of the EC rendered COA tolerant to long ISI. Because EC lesions induce a septo-hippocampal cholinergic sprouting, the present experiment investigated whether COA tolerance to long ISI may be linked to this sprouting reaction. In a first experiment, male Long-Evans rats subjected to bilateral excitotoxic EC lesions combined to intracerebroventricular infusions of the selective cholinergic immunotoxin 192 IgG-saporin were exposed to odor-toxicosis pairing using a long ISI (120 min). Results showed that EC-lesioned rats displayed COA with the long ISI but not the control groups. In rats with EC combined to 192 IgG-saporin lesions, histological analysis demonstrated no evidence for cholinergic septo-hippocampal sprouting. In a second experiment, animals with 192-IgG saporin lesion showed a marked COA with a short ISI (5 min). These results suggest that the COA with the long ISI found in rats with EC lesions might involve a functional activity related to the EC lesion-induced hippocampal cholinergic sprouting. As the injection of 192 IgG-saporin alone did not affect COA with a short ISI, our data also point to a possible role of hippocampal cholinergic neurons in the modulation of memory processes underlying COA.
