Communication styles of children of mothers with affective disorders,chronic medical illness,and normal controls: A contextual perspective

Research has demonstrated impaired parent-child relationships in families with affective disorders. The present study examines the association of children's interactional style during a direct conflict-solving task to both the mother's interactional style and the child's diagnostic status. The sample includes 63 children, ages 8 to 16, of mothers with affective disorders, chronic medical illness, and normal controls. Children's dominant coping style profile (CS) (autonomous, neutral, or critical) was related to their mother's affective style (AS) (benign or negative). Affective disorder in the child at 6-month followup was associated with a critical CS profile at intake, while the child's nonaffective symptomatology was unrelated to CS. Findings indicate that children's affective disturbance is linked to interpersonal deficits in affectively charged situations. Results suggest that the child's CS is more strongly predicted by maternal aa than by either the child's or the mother's diagnostic status.This research was supported in part by an award from the William T.

Early executive control and risk for overweight and obesity in elementary school

An emerging literature suggests that poor executive control (EC) may be associated with clinical weight problems, e.g., body mass index (BMI) for age percentile ≥85 in children. However, our understanding of the impact of EC on overweight and obesity in childhood is limited by the lack of longitudinal studies spanning critical developmental periods and assessing EC using comprehensive performance-based batteries. The current study addresses these limitations in a longitudinal examination of 212 children who completed an extensive laboratory-based EC task battery in preschool (age 4 years and 6 months) and were followed through elementary school (Grades 1 through 4) with objective measures of weight status. The logistic regression results indicate that poorer EC in preschool is associated with significantly greater risk for clinical weight problems (either overweight or obese status, as defined by BMI-for-age percentile ≥ 85) in elementary school, controlling for maternal education. EC in preschool was not significantly associated with risk for obese status, specifically (defined by BMI-for-age percentile ≥ 95), but the trend was in the expected direction. The results suggest that early executive abilities are relevant for children’s subsequent health status, with deficits in EC in the critical period of preschool conferring risk for later problems with weight. Based on these findings, early interventions to promote stronger EC may be a promising, yet currently overlooked, component in pediatric obesity prevention efforts.     

McGurk stimuli for the investigation of multisensory integration in cochlear implant users: The Oldenburg Audio Visual Speech Stimuli (OLAVS)

The concurrent presentation of different auditory and visual syllables may result in the perception of a third syllable, reflecting an illusory fusion of visual and auditory information. This well-known McGurk effect is frequently used for the study of audio-visual integration. Recently, it was shown that the McGurk effect is strongly stimulus-dependent, which complicates comparisons across perceivers and inferences across studies. To overcome this limitation, we developed the freely available Oldenburg audio-visual speech stimuli (OLAVS), consisting of 8 different talkers and 12 different syllable combinations. The quality of the OLAVS set was evaluated with 24 normal-hearing subjects. All 96 stimuli were characterized based on their stimulus disparity, which was obtained from a probabilistic model (cf. Magnotti & Beauchamp, 2015). Moreover, the McGurk effect was studied in eight adult cochlear implant (CI) users. By applying the individual, stimulus-independent parameters of the probabilistic model, the predicted effect of stronger audio-visual integration in CI users could be confirmed, demonstrating the validity of the new stimulus material.     

The importance of being flexible: the ability to both enhance and suppress emotional expression predicts long-term adjustment

Researchers have documented the consequences of both expressing and suppressing emotion using between-subjects designs. It may be argued, however, that successful adaptation depends not so much on any one regulatory process, but on the ability to flexibly enhance or suppress emotional expression in accord with situational demands. We tested this hypothesis among New York City college students in the aftermath of the September 11th terrorist attacks. Subjects' performance in a laboratory task in which they enhanced emotional expression, suppressed emotional expression, and behaved normally on different trials was examined as a prospective predictor of their adjustment across the first two years of college. Results supported the flexibility hypothesis. A regression analysis controlling for initial distress and motivation and cognitive resources found that subjects who were better able to enhance and suppress the expression of emotion evidenced less distress by the end of the second year. Memory deficits were also observed for both the enhancement and the suppression tasks, suggesting that both processes require cognitive resources.     

Factors regulating the effects of hippocampal inactivation on renewal of conditional fear after extinction

After extinction of fear to a Pavlovian conditional stimulus (CS), contextual stimuli come to regulate the expression of fear to that CS. There is growing evidence that the context dependence of memory retrieval after extinction involves the hippocampus. In the present experiment, we examine whether hippocampal involvement in memory retrieval after extinction is related to the history of CS presentations in the context used for retrieval testing. We used infusions of muscimol to inactivate the dorsal hippocampus (DH) during postextinction retrieval tests that were conducted in contexts that differed in their history of CS presentations in that context. We found that DH inactivation affected the context-dependent retrieval of extinction (i.e., renewal) when testing occurred in a context that had no history of CS exposure, but not in a context that reliably predicted the CS. These results are discussed in terms of theories regarding the role of the hippocampus in contextual memory retrieval.     

Social modulation of learning in rats

It is well known that emotions participate in the regulation of social behaviors and that the emotion displayed by a conspecific influences the behavior of other animals. In its simplest form, empathy can be characterized as the capacity to be affected by and/or share the emotional state of another. However, to date, relatively little is known about the mechanisms by which animals that are not in direct danger share emotions. In the present study, we used a model of between-subject transfer of fear to characterize the social interaction during which fear is transmitted, as well as the behavioral effects of socially transmitted fear. We found that (1) during social interaction with a recently fear-conditioned partner, observers and demonstrators exhibit social exploratory behaviors rather than aggressive behaviors; (2) learning and memory in a shock-motivated shuttle avoidance task are facilitated in rats that underwent a social interaction with a partner that had been fear conditioned; and (3) a brief social interaction with a recently fear-conditioned partner immediately before fear conditioning increases conditioned freezing measured on the next day. The observed effects were not due to a stress-induced increase in pain sensitivity or analgesia. Collectively, these data suggest that a brief social interaction with a cage mate that has undergone an aversive learning experience promotes aversive learning in an otherwise naïve animal. We argue that socially transferred fear is an adaptation that promotes defensive behavior to potentially dangerous situations in the environment.Human empathy can be defined as the ability to experience and share the thoughts and feelings of others (de Waal 2008). Obviously, this is a complex social phenomenon that, until recently, has received much attention from philosophers and psychologists rather than neuroscientists (Decety and Lamm 2006). However, in its simplest form, empathy can be characterized as the capacity to be affected by and/or share the emotional state of another (de Waal 2008). Tuning one''s emotional state to that of another increases the probability of similar behavior, which thereby allows rapid adaptation to environmental challenges (Hatfield et al. 1994). This social adaptation may be particularly important for emotions that signal a potential danger, such as fear. Although one can learn about potentially harmful stimuli by directly experiencing an aversive event, observation or interaction with a conspecific in danger and/or in pain may also provide information about threats in the environment. There is a vast literature on learning about direct danger (Maren 2001) as well as sharing emotions through observation (see, e.g., Church 1959; Langford et al. 2006; Olsson and Phelps 2007). However, relatively little is known about the mechanisms by which animals that are not in a direct danger share emotions.We have recently designed an experimental rat model of between-subject transfer of emotional information (Knapska et al. 2006). In this model, rats are housed in pairs and one member of the pair (the “demonstrator”) is removed and subjected to fear conditioning. After the fear-conditioning episode, the conditioned animal is allowed to interact with its naïve cage mate (the “observer”). We showed that the demonstrator''s fear is socially transferred to the observer, resulting in both rapid increase in exploratory behavior of the observer and a pattern of c-Fos activation in the observer''s amygdala that parallels that of the shocked demonstrators.These results suggest that the social interaction between the demonstrator and observer results in a transfer of information that promotes aversively motivated learning in the observer. However, the nature of the social interaction and how it comes to influence aversively motivated behavior is not known. Therefore, the present study aimed to characterize the behavior of both the demonstrators and observers during their social interaction and further characterize the nature of the influence of socially transmitted fear on aversively motivated learning and memory. We hypothesized that the social interaction between observers and demonstrators would result in a social transfer of fear that would promote learning and memory of both active defensive responses (avoidance) as well as defensive immobility (freezing). To test this hypothesis, we carried out five experiments that examined the nature of the social interaction between shocked demonstrators and observers (Experiment 1), the acquisition and retention of active avoidance (Experiment 2), and conditioned freezing (Experiment 3). Because it is not clear if social transfer effects can be observed among unfamiliar animals and to control for social buffering, we also compared the social transfer of fear in familiar and unfamiliar rats (Experiment 4). To control for the possible influence of different pain sensitivity thresholds in the observers paired with shocked demonstrators, we carried out pain tests (Experiment 5).     

Community psychology,digital technology,and loss: Remembrance activities of young adults who have experienced the death of a close friend

We argue for community psychology to include digital communications technology in research on ways that the social environment shapes fundamental human experiences. We present a qualitative study that examined the narrative accounts of 20 young adults who experienced the death of a close friend to describe both traditional and digital forms of remembrance in coping with loss. Findings suggest that young adults' activities both online and offline were intended to acknowledge the loss, exchange social support, create and sustain memories of their deceased friend, and facilitate continued communication with the deceased. Participants described both costs and benefits to their real and virtual remembrance activities. Findings illustrate ways that the study of digital technology adds to our understanding of grief and bereavement and contributes to dominant cultural narratives about coping with death. Implications of findings for research in community psychology are discussed.     

Normative Embodiment. The Role of the Body in Foucault's Genealogy. A Phenomenological Re-Reading

In Foucault's later works, experience and embodiment become important for explaining the normative constitution of the subject: for norms to be effective, discourses are insufficient – they must be experienced and embodied. Practices of “discipline” inscribe power constellations and discourses into subjective experience and bodies. In his lectures on the Hermeneutics of the Subject, he turns this “violent” form of normative embodiment into an ethical perspective by referring to the Stoic tradition. Even though Foucault never developed a notion of experience and embodiment himself, his ideas can be re-read and complemented from a phenomenological perspective.

The article tries to investigate the role of bodily experience and practice in Foucault's Genealogy and to bring it into dialogue with Husserl and Merleau-Ponty's conceptions of the lived body. It will attempt to show that concepts like sedimentation and habituality can help to explain how cultural norms not only influence the way we think about, but also how we perceive and are affected by the world. This operation of norms happens already at the lowest stages of experience, where embodied experience leaves its traces, in sedimentation and habitualization. These passive layers of experience are permeable to historical discourses, so that norms are literally inscribed in the body. These are the foundations for what I seek to define as normative embodiment.
