Associations Between Infant Brain Activity and Recall Memory

Long‐term explicit memory is thought to involve a complex neural circuit including the medial temporal lobe, the medial diencephalon, the prefrontal cortex, and association cortices. When this memory system and associated neural circuitry develops is of great interest to developmental psychologists and developmental cognitive neuroscience researchers. In the present report, we provide evidence of a relation between behavioral and neurophysiological measures of long‐term explicit memory in 9‐month‐old infants. These measures provide converging evidence of the development of long‐term explicit memory at least by the end of the first year of life.     

Personality and Religion Among Music Students

A sample of 422 students attending courses in eleven departments or colleges of music completed the short form of the Revised Eysenck Personality Questionnaire together with the Francis Scale of Attitude toward Christianity and measures of prayer and church attendance. In comparison with the population norms, both male and female music students recorded significantly higher scores on the extraversion scale and significantly lower scores on the psychoticism scale. The data confirm that psychoticism is the dimension of personality fundamental to individual differences in religiosity.     

Effects of Equine-Facilitated Psychotherapy on Post-Traumatic Stress Symptoms in Youth

Equine-assisted therapy has become an increasingly popular complementary mental health treatment approach, but there is limited empirical research assessing the effectiveness of this practice. In particular, equine-facilitated psychotherapy has many potential benefits for the treatment of trauma in youth. The purpose of the proposed study was to investigate changes in levels of post-traumatic stress symptomatology and levels of the human-animal bond in children and adolescents ages 10–18 over the course of a 10-week equine-facilitated psychotherapy (EFP) intervention. Youth in the treatment group (n?=?36) participated in 10 weekly two hour EFP sessions, and were compared on changes in post-traumatic stress symptoms with a control group of participants (n?=?32) who continued to receive the already existing traditional therapeutic services provided by their treatment facility or outpatient therapist. Findings suggested a significant decrease in post-traumatic stress symptoms across the intervention for both the treatment and control group, but the treatment group did not decrease significantly more than the control group. These findings suggest that EFP may be an effective additional treatment modality for post-traumatic stress symptoms, but there was no evidence from this initial study that EFP was significantly more effective than traditional office-based therapy. Further research and discussion of the relative benefits of EFP compared to traditional treatment modalities is warranted.     

A Cost Analysis of a Validated Screening Tool for Pediatric Abusive Head Trauma

Doctors who treat young victims of trauma are required to make important decisions to launch or forgo child abuse evaluations in their acutely head-injured patients. To improve the accuracy of these decisions, Pediatric Brain Injury Research Network (PediBIRN) investigators derived and validated a 4-variable clinical prediction rule (CPR) that improves the detection of abusive head trauma (AHT) in pediatric intensive care units. Our objective was to estimate and compare medical costs from the health system perspective of AHT screening guided by the CPR vs. screening as usual (SAU). Cost estimates for child abuse evaluations, emergency department (ED)/pediatrician visits, and hospital admissions for AHT were combined with published data on service use and re-injury rates in children with missed or unrecognized AHT. Applying published estimates of the CPR’s potential screening performance, the cost per correctly identified child with AHT was calculated and compared for AHT screening guided by the CPR vs. SAU, and the potential medical cost savings associated with CPR application was estimated. Applied accurately and consistently, the CPR could reduce the cost per correctly identified child with AHT by 15.1%, and reduce health system costs resulting from missed AHT by 72.4%.     

Infant perception of a manual pick-up event

Manual pick-up of an object is a simple causal event frequently observed by infants. A habituation-recovery of looking technique with filmed stimuli is used in experiments which seek to investigate aspects of the perception and encoding of such events in infants. In the first study with 28-week-olds, it is found that ‘lateral mirror-image’ pick-ups are hardly discriminable, while a change in the contact relation of hand and object is readily discriminable. In the second, again with 28-week-olds, the discriminability of the contact relation appears to be specific to a dynamic context involving a hand (rather than another inanimate object). The results of a further experiment make it appear unlikely that the previous results were simply due to the partial occlusion of the picked-up object produced by the grasping. The implications of these results for infant perception of causality are briefly considered.
