Relationships and the social brain: integrating psychological and evolutionary perspectives

Psychological studies of relationships tend to focus on specific types of close personal relationships (romantic, parent-offspring, friendship) and examine characteristics of both the individuals and the dyad. This paper looks more broadly at the wider range of relationships that constitute an individual's personal social world. Recent work on the composition of personal social networks suggests that they consist of a series of layers that differ in the quality and quantity of relationships involved. Each layer increases relationship numbers by an approximate multiple of 3 (5-15-50-150) but decreasing levels of intimacy (strong, medium, and weak ties) and frequency of interaction. To account for these regularities, we draw on both social and evolutionary psychology to argue that relationships at different layers serve different functions and have different cost-benefit profiles. At each layer, the benefits are asymptotic but the costs of maintaining a relationship at that level (most obviously, the time that has to be invested in servicing it) are roughly linear with the number of relationships. The trade-off between costs and benefits at a given level, and across the different types of demands and resources typical of different levels, gives rise to a distribution of social effort that generates and maintains a hierarchy of layered sets of relationships within social networks. We suggest that, psychologically, these trade-offs are related to the level of trust in a relationship, and that this is itself a function of the time invested in the relationship.     

The relationship between acculturation preferences and prejudice: Longitudinal evidence from majority and minority groups in three European countries

A longitudinal field survey tested the reciprocal effects of acculturation preferences and prejudice among ethnic minorities and majorities. Data were collected at two points in time from 512 members of ethnic minorities and 1143 majority members in Germany, Belgium and England. Path analyses yielded not only the lagged effects of prejudice on acculturation preferences but also the reverse for both majority and minority members. The mutual longitudinal effects between prejudice and desire for culture maintenance were negative, and the mutual effects between prejudice and desire for culture adoption were positive for majority members. The reverse was the case for minority participants. Moreover, the two acculturation dimensions interacted in their effect on prejudice for majority participants but not for minority participants. The effect of desire for culture adoption on prejudice was moderated by perceived intergroup similarity. Theoretical and practical implications of the findings are discussed.

Development through interruptions and reparations – A case study of a dual challenging psychotherapy

The aim of this study was to understand how relational difficulties in psychotherapy may be handled to represent possibilities for change. Temporary interruptions and subsequent reestablishment of contact were chosen as the strategic focus in one severely challenging case of long term psychodynamic psychotherapy where outcome was known to be good. Interruptions and reestablishments were conceptualised by how the informants gave meaning to them. The choice of focus represented a strategic selection of events in the course of therapy where the regulation of the alliance by the therapist as well as by the patient was at stake. A detailed case record was studied and interviews with patient and therapist were conducted. A hermeneutical-phenomenological approach was used to analyse the material. The narrative dimension was important in structuring and interpreting the data. It was shown how important relational difficulties, such as mutual incompatible expectations and demands was handled both on a structural and interpersonal level, and some important steps and hallmarks of the healing process was identified. Close inspection of the course of events in psychotherapies is seen as a promising method for bringing a better understanding of how change processes unfold.     

Feeling accepted: A phenomenological exploration of adolescent patients’ experiences of the relational qualities that enable them to express themselves freely

Objectives: The aim of this study was to explore adolescent psychotherapy patients’ experiences of the relational qualities that make it possible for them to express themselves freely and to continue their self-consolidation.Design: An interview-based study using thematic analysis based on hermeneutical–phenomenological epistemology.Methods: Semi-structured in-depth qualitative interviews with 14 adolescents.Results: The adolescents’ experiences were clustered around five themes: (1) receiving full and genuine attention; (2) not having to take care of and responsibility for the therapist; (3) being accepted and valued; (4) the therapist staying with them through emotionally painful moments; and (5) the therapist facilitating openness by sharing.Conclusions: The results from the current study suggest that there are particular ways that therapists can relate to adolescent patients which would make them feel more able to express themselves freely and that create an atmosphere which facilitates the consolidation of the adolescents’ sense of self.     

Faceting of a rough solid–liquid interface of a metal induced by forced convection

The solid–liquid interface of metallic systems of small entropy of fusion is characterized by a rough interface and dendritic morphology. In contrast, systems of high entropy of fusion like semimetals and semiconductors show smooth interfaces and facetted interfaces. The present work demonstrates that, in an undercooled melt of a metal–metalloid alloy Ni₂B of intermediate entropy of fusion, a transition from a rough to a smooth interface is induced by forced convection of the melt. Electrostatic levitation is used to container-less undercool droplets in a quiescent state with no convection while electromagnetic levitation (EML) is used to undercool droplets with forced convection. The growth velocity of the solid phase is monitored as a function of undercooling by a high-speed video camera. The data are analysed within dendrite growth theory. In the case of EML, a transition from a rough to a smooth interface is indicated during dendrite growth in the undercooled melt. This is confirmed by facetted microstructures of samples solidified upon undercooling by EML. Hopper-like crystals are formed like in non-metals as bismuth, halite and ice.     

Parkinson’s disease disrupts both automatic and controlled processing of action verbs

The problem of how word meaning is processed in the brain has been a topic of intense investigation in cognitive neuroscience. While considerable correlational evidence exists for the involvement of sensory-motor systems in conceptual processing, it is still unclear whether they play a causal role. We investigated this issue by comparing the performance of patients with Parkinson’s disease (PD) with that of age-matched controls when processing action and abstract verbs. To examine the effects of task demands, we used tasks in which semantic demands were either implicit (lexical decision and priming) or explicit (semantic similarity judgment). In both tasks, PD patients’ performance was selectively impaired for action verbs (relative to controls), indicating that the motor system plays a more central role in the processing of action verbs than in the processing of abstract verbs. These results argue for a causal role of sensory-motor systems in semantic processing.     

Rebuild or Relocate? Resilience and Postdisaster Decision‐Making After Hurricane Sandy

Hurricane Sandy struck the east coast of the United States on October 29, 2012, devastating communities in its path. In the aftermath, New York implemented a home buyout program designed to facilitate the permanent relocation of residents out of areas considered to be at risk for future hazards. While home buyout programs are becoming popular as policy tools for disaster mitigation, little is known about what factors influence homeowners to participate in or reject these programs. This study used mixed methods to assess the relationship between community resilience and the relocation decision in two heavily damaged communities in which the majority of residents made different decisions regarding whether or not to pursue a buyout. The sample was composed of residents from Oakwood Beach and Rockaway Park, both working‐class communities in New York City, who participated via a community survey (N = 133) and/or in‐depth interviews (N = 28). Results suggested that community resilience moderated the relationship between community of residence and the buyout decision, leading to opposite responses on the buyout decision. Contextual community factors, including the history of natural disasters, local cultural norms, and sense of place, were instrumental in explaining these different responses. Implications for disaster policy are discussed.
