A Goodness-of-Fit Approach to Informed Consent for Pediatric Intervention Research

As children and adolescents receive increased research attention, ethical issues related to obtaining informed consent for pediatric intervention research have come into greater focus. In this article, we conceptualize parent permission and child assent within a goodness-of-fit framework that encourages investigators to create consent procedures “fitted” to the research context, the child's cognitive and emotional maturity, and the family system. Drawing on relevant literature and a hypothetical case example, we highlight four factors investigators may consider when constructing consent procedures that best reflect participants' rights, concerns, and well-being: (a) the child's current assent capacity and the likely impact of study information on the child's mental and physical development, (b) parents' understanding of their child's treatment needs and distinctions between treatment and clinical trials research, (c) the family's history of shared decision making, and (d) the child's strivings for autonomy within the context of their parents' duty to make decisions in the child's best interest.     

Effects of experimentally induced dissociation on attention and memory

Dissociation is an important aspect of responses to traumatic events. According to a number of influential theories, it negatively impacts cognitive performance including encoding of the trauma memories, leading to an increased risk of later conditions such as posttraumatic stress disorder (PTSD). We tested this hypothesis experimentally in two studies by inducing dissociation in the laboratory and investigating the effects on several aspects of cognition, including time estimation, digit and spatial span, and story recall. Dissociation was related to decrements in time estimation, digit span, and story retention, but did not affect perceptual attention, spatial span, or immediate story recall. The results are discussed in the context of theoretical models of PTSD and their implications for official questioning of traumatized individuals such as sexual assault survivors.     

Guilt by association and honor by association: The role of acquired equivalence

Guilt by association and honor by association are two types of judgments that suggest that a negative or positive quality of a person or object can transfer to another person or object, merely by co-occurrence. Most examples have been demonstrated under conditions of direct associations. Here, we provide experimental evidence of guilt by association and honor by association via indirect associations. We show that participants may treat two individuals alike if they have been separately paired with a common event using an acquired-equivalence paradigm. Our findings suggest that association fallacies can be examined using a paradigm originally developed for research with nonhuman animals and based on a representation mediation account.     

Ageing faces in ageing minds: A review on the own-age bias in face recognition

Similar to the well-established own-race bias, participants are more accurate at remembering own- relative to other-age faces. An own-age bias (OAB) in face memory was demonstrated in participants older than approximately 5 years. Crucially, the OAB is modulated by contact—participants with substantial contact with other-age persons show either reduced or absent OAB effects. In line with a perceptual expertise account of the phenomenon, holistic processing of other-age faces is less efficient when tested with young adult versus child faces, and differential holistic processing may therefore reflect one mechanism contributing to the OAB. A possible additional contribution of sociocognitive factors to the OAB remains largely untested. Importantly, event-related brain potential studies suggest that the own-race and own-age biases are based on at least partly different mechanisms. Theoretical explanations for different group-based biases in face memory will need to consider these findings.     

Working memory demands in insight versus analytic problem solving

Working memory is one of the cognitive processes thought to differentiate insight and analytic forms of problem solving. The present research examined memory involvement in the solution of insight versus analytic problems. Participants completed verbal and spatial working memory and short-term memory measures and a series of analytic and insight problems. Results demonstrated a relationship between working-memory capacity and the solution of analytic problems and between verbal short-term memory capacity and the solution of insight problems. This distinction was generally though not universally supported when memory was examined in relation to individual problems. Memory involvement in insight problem solving was further examined to clarify whether restructuring in insight is the end result of active memory search or spontaneous processes. The present research supports the theory that differences exist in the cognitive processes underlying insight versus analytic problem solving, and provides support for the spontaneous theory of restructuring in insight.     

Seeing,mirroring, desiring: The impact of the analyst’s pregnant body on the patient’s body image

The paper explores the impact of the analyst’s pregnant body on the course of two analyses, a young man, and a young woman, specifically focusing on how each patient’s visual perception and affective experience of being with the analyst’s pregnant body affected their own body image and subjective experience of their body. The pre‐verbal or ‘subsymbolic’ material evoked in the analyses contributed to a greater understanding of the patients’ developmental experiences in infancy and adolescence, which had resulted in both carrying a profoundly distorted body image into adulthood. The analyst’s pregnancy offered a therapeutic window in which a shift in the patient’s body image could be initiated. Clinical material is presented in detail with reference to the psychoanalytic literature on the pregnant analyst, and that of the development of the body image, particularly focusing on the role of visual communication and the face. The author proposes a theory of psychic change, drawing on Bucci’s multiple code theory, in which the patients’ unconscious or ‘subsymbolic’ awareness of her pregnancy, which were manifest in their bodily responses, feeling states and dreams, as well as in the analyst s countertransference, could gradually be verbalized and understood within the transference. Thus visual perception, or ‘external seeing’, could gradually become ‘internal seeing’, or insight into unconscious phantasies, leading to a shift in the patients internal object world towards a less persecutory state and more realistic appraisal of their body image.     

The Relationship Between Women's Body Satisfaction and Self-Image Across the Life Span: The Role of Cognitive Control

The authors examined the relationship between body dissatisfaction and self-image across the life span. A sample of 106 women between the ages of 20 and 65 years completed questionnaire measures of body dissatisfaction, body importance, cognitive control over the body, self-concept, and self-esteem. The authors found that body dissatisfaction and body importance did not differ among the groups of women who were younger, middle aged, and older. Although body dissatisfaction was related to self-concept and self-esteem for the entire sample, the strength of that relationship reduced with increasing age and increasing perceptions of cognitive control. The authors concluded that the cognitive strategies of women who were older protect their self-concept and self-esteem from the influence of body dissatisfaction.     

Postural Asymmetries in Response to Holding Evenly and Unevenly Distributed Loads During Self-Selected Stance

The authors examined postural asymmetries during quiet stance and while holding evenly or unevenly distributed loads. Right-hand dominant subjects preferentially loaded their right lower limb when holding no load or a load evenly distributed in both hands, but no differences in center of pressure (CoP) were observed between the left and right limbs. However, longer CoP displacement was observed under the preferentially loaded limb, which may reflect a functional asymmetry that allows quick movement of one limb in response to a potential perturbation. When a load was held only in the nondominant hand, sample entropy decreased in the left (loaded) limb but increased in the right (unloaded) limb, suggesting the unloaded foot compensated for a loss of control flexibility in the loaded foot.     

Effects of Induced Emotional State on Lexical Processing in Younger and Older Adults

The authors investigated the effects of an induced emotional mood state on lexical decision task (LDT) performance in 50 young adults and 25 older adults. Participants were randomly assigned to either happy or sad mood induction conditions. An emotional mood state was induced by having the participants listen to 8 min of classical music previously rated to induce happy or sad moods. Results replicated previous studies with young adults (i.e., sad-induced individuals responded faster to sad words and happy-induced individuals responded faster to happy words) and extended this pattern to older adults. Results are discussed with regard to information processing, aging, and emotion.
