Angels in the nursery: The intergenerational transmission of benevolent parental influences

Fraiberg and her colleagues (1975) introduced the metaphor “ghosts in the nursery” to describe the ways in which parents, by reenacting with their small children scenes from the parents' own unremembered early relational experiences of helplessness and fear, transmit child maltreatment from one generation to the next. In this article we propose that angels in the nursery—care‐receiving experiences characterized by intense shared affect between parent and child in which the child feels nearly perfectly understood, accepted, and loved—provide the child with a core sense of security and self‐worth that can be drawn upon when the child becomes a parent to interrupt the cycle of maltreatment. We argue that uncovering angels as growth‐promoting forces in the lives of traumatized parents is as vital to the work of psychotherapy as is the interpretation and exorcizing of ghosts. Using clinical case material, we demonstrate the ways in which early benevolent experiences with caregivers can protect against even overwhelming trauma, and examine the reemergence of these benevolent figures in consciousness as an instrument of therapeutic change. Finally, we examine implications of the concept of “angels in the nursery” for research and clinical intervention.     

Traumatic stress and quality of attachment: Reality and internalization in disorders of infant mental health

This article describes the interface between the fields of attachment and child trauma, their respective contributions to an understanding of infant mental health disturbances, and the clinical applications of an integration between attachment theory and trauma‐informed treatment and research. The organizing theme is that a dual attachment and trauma lens must be used in the assessment and treatment of infants and toddlers with mental health and relationship problems. The quality of attachment is an important factor in children's capacity to process and resolve traumatic experiences. At the same time, traumatic events often have a damaging effect on the quality of existing attachments by introducing unmanageable stress in the infant–parent relationship. It is argued that trauma in the first years of life needs to be assessed and treated in the context of the child's primary attachments. Reciprocally, the etiology of attachment disturbances should include an assessment of possible exposure to trauma in the child and in the parents. Current conceptualizations of attachment and trauma are reviewed from this perspective, and a clinical illustration is presented to highlight how a traumatic stressor can trigger behaviors reminiscent of disorganized attachment.     

Caffeine modulates attention network function

The present work investigated the effects of caffeine (0 mg, 100 mg, 200 mg, 400 mg) on a flanker task designed to test Posner’s three visual attention network functions: alerting, orienting, and executive control [Posner, M. I. (2004). Cognitive neuroscience of attention. New York, NY: Guilford Press]. In a placebo-controlled, double-blind study using a repeated-measures design, we found that the effects of caffeine on visual attention vary as a function of dose and the attention network under examination. Caffeine improved alerting and executive control function in a dose–response manner, asymptoting at 200 mg; this effect is congruent with caffeine’s adenosine-mediated effects on dopamine-rich areas of brain, and the involvement of these areas in alerting and the executive control of visual attention. Higher doses of caffeine also led to a marginally less efficient allocation of visual attention towards cued regions during task performance (i.e., orienting). Taken together, results of this study demonstrate that caffeine has differential effects on visual attention networks as a function of dose, and such effects have implications for hypothesized interactions of caffeine, adenosine and dopamine in brain areas mediating visual attention.     

Acute caffeine consumption enhances the executive control of visual attention in habitual consumers

Recent work suggests that a dose of 200–400 mg caffeine can enhance both vigilance and the executive control of visual attention in individuals with low caffeine consumption profiles. The present study seeks to determine whether individuals with relatively high caffeine consumption profiles would show similar advantages. To this end, we examined the effects of four caffeine doses (0 mg, 100 mg, 200 mg, 400 mg) on low- and high-level visual attention in individuals with high consumption profiles (n = 36), in a double-blind study using a repeated measures design. Results from the Attention Network Test indicated that caffeine enhanced both vigilance and the executive control of visual attention, but only at the highest administered dose (400 mg). We demonstrate that in habitual consumers high doses of caffeine can produce beneficial changes in visual attention. These results carry implications for the theorized interactions between caffeine, adenosine and dopamine in brain regions mediating visual attention.     

Dissociable neural systems support retrieval of how and why action knowledge

In everyday discourse, people typically represent actions in one of two ways: how they are performed or why they are performed. In the present study, we determined the neural systems that support these natural modes of representing actions. Participants underwent functional magnetic resonance imaging while identifying how and why people perform various familiar actions. Identifying how actions are performed produced activity in premotor areas that support the execution of actions and in higher-order visual areas that support the perception of action-related objects; this finding supports an embodied view of action knowledge. However, identifying why actions are performed preferentially engaged areas of the brain associated with representing and reasoning about mental states; these areas were right temporoparietal junction, precuneus, dorsomedial prefrontal cortex, and posterior superior temporal sulcus. Our results suggest that why action knowledge is not sufficiently constituted by information in motor and visual systems, but requires a system for representing states of mind, which do not have reliable motor correlates or visual appearance.     

Impulsive choice and altruistic punishment are correlated and increase in tandem with serotonin depletion

Human cooperation may partly depend on the presence of individuals willing to incur personal costs to punish noncooperators. The psychological factors that motivate such 'altruistic punishment' are not fully understood; some have argued that altruistic punishment is a deliberate act of norm enforcement that requires self-control, while others claim that it is an impulsive act driven primarily by emotion. In the current study, we addressed this question by examining the relationship between impulsive choice and altruistic punishment in the ultimatum game. As the neurotransmitter serotonin has been implicated in both impulsive choice and altruistic punishment, we investigated the effects of manipulating serotonin on both measures. Across individuals, impulsive choice and altruistic punishment were correlated and increased following serotonin depletion. These findings imply that altruistic punishment reflects the absence rather than the presence of self control, and suggest that impulsive choice and altruistic punishment share common neural mechanisms.     

BIS,BAS, and response conflict: Testing predictions of the revised reinforcement sensitivity theory

Gray’s (1970) reinforcement sensitivity theory (RST) was recently updated (Gray & McNaughton, 2000), but the changes have not received extensive empirical validation. The study tests three novel predictions of the revised RST. First, the behavioral activation system (BAS) is expected to be sensitive to both conditioned and unconditioned incentives. Second, the behavioral inhibition system (BIS) is expected to be sensitive to conflicting incentives such as between unconditioned and conditioned stimuli, and not to avoidance responses or aversive stimuli alone. Third, during approach-avoidance conflicts only, BAS is expected to moderate BIS responses to conflict such that individuals with high BAS show the strongest effect of BIS. In order to test these hypotheses, we developed a novel incentive task that crosses approach/avoidance conditioned responses to appetitive/aversive unconditioned stimuli. Conflict between unconditioned and conditioned stimuli occurred on the approach-aversive and avoid-appetitive trials. Results confirm the predictions and provide support for the revised RST.     

Anorexia nervosa: the tyranny of appearances

This paper explores the possibility that many families of anorexics are overly preoccupied with appearances, valuing what other people think of them more than healthier families do, and that this influences the origin and maintenance of anorexia. This‘rule’is simple and should be open to testing more widely through research.
