Student volunteer social support and infant intervention: A case study

The emphases in infant mental health have been in the three areas of supporting the mother-infant dyad through education, psychotherapy to help parents resolve emotional conflicts that interfere with the parent-infant interaction, and support during the acute crisis that follows an abnormal birth. The case described herein involves a child with a genetic defect born to competent parents, a chronic stressful situation that does not fit these categories. It became apparent in the first few months after the birth that both the child and parents were in need of some help in coping with the situation. An intervention was designed to help provide both the necessary stimulation for the baby and the needed emotional support for the family, while it acknowledged their skill and competencies as parents. This was done through the help of college student volunteers, who assisted the mother in the home. Developmental data recorded at birth, 7 months, 12 months, and 39 months indicate that the child is severely multiply handicapped. Interview data with the parents at those times document their personal and family difficulties, the eventual resolution as a family in dealing with this problem, and the importance of the volunteer help during that process.     

Fear and aggression in the rat

The effect of fear on two types of aggression in rats was investigated by adding a cat stimulus to a colony in which the dominant male was attacking an intruder (offensive aggression), or, to a tube test situation in which defensive biting was measured before and during tail shock. The cat completely abolished offense in the colony; when the cat was presented and removed before a strange rat was placed in the colony, attack on the intruder was also reduced. In contrast, defensive biting was unchanged or even slightly potentiated by the presence of the cat, demonstrating a separation of the effects of fear on offensive and defensive aggression.     

Virtual reality and the new psychophysics

Virtual reality (VR) promises methodological rigour with the extra benefit of allowing us to study the context-dependent behaviour of individuals in their natural environment. Pan and Hamilton (2018, Br. J. Psychol.) provide a useful overview of methodological recommendations for using VR. Here, we highlight some other aspects of the use of VR. Our first argument is that VR can be useful by virtue of its differences from the normal perceptual environment. That is, by virtue of its relative non-realism and poverty of its perceptual elements, it can actually offer increased clarity with respect to the features of interest for the researcher. Our second argument is that VR exerts its measurable influence more by eliciting an acceptance of the virtual world (i.e., ‘suspension of disbelief’) rather than by eliciting a true belief of the realism of the VR environment. We conclude by providing a novel suggestion for combining neuroimaging methods with embodied VR that relies on the suspension of disbelief.
