What shall we do with emergence? A survey of a fundamental issue in the metaphysics and epistemology of science

A survey of some recent literature on the concept of emergence provides a case study of an important issue in the general metaphysics and epistemology of science. Emergentism has often been motivated by the desire to avoid excessive reductionism in the philosophy of mind and culture and in the respective fields of the philosophy of science—philosophy of psychology and of the human and social sciences. Philosophers employing the concept of emergence usually argue that there are several ‘levels’ of reality and that the entities and properties of the ‘higher’ levels (e.g., mentality) emerge from those of the ‘lower’ ones (e.g., the physical universe). The standard division between ontological and epistemological approaches to this concept is shown to be inadequate through a critical discussion of emergence from the perspective of a pragmatist philosophy of science. It is argued that emergence should be conceived of both ontologically and epistemologically, because there is no humanly possible point of view for ontologizing about the way the world is structured in itself, entirely independently of our epistemic standpoints. Emergence thus turns out to be an example of the way in which the ‘pre-critical’ dispute between dogmatic metaphysics and skeptical reactions to it (which Kant famously wanted to overcome) still dominates philosophy of science. Hence, the problems of emergence and realism are observed to be intimately connected.     

Socioemotional selectivity in older adults: Evidence from the subjective experience of angry memories

Few studies have compared the phenomenological properties of younger and older adults' memories for emotional events. Some studies suggest that younger adults remember negative information more vividly than positive information whereas other studies suggest that positive emotion yields phenomenologically richer memories than negative emotion for both younger and older adults. One problem with previous studies is a tendency to treat emotion as a dichotomous variable. In contrast, emotional richness demands inclusion of assessments beyond just a positive and negative dimension (e.g., assessing specific emotions like anger, fear and happiness). The present study investigated different properties of autobiographical remembering as a function of discrete emotions and age. Thirty-two younger and thirty-one older adults participated by recalling recent and remote memories associated with six emotional categories and completed the Memory Characteristics Questionnaire for each. Results demonstrated that older adults' angry memories received lower ratings on some phenomenological properties than other emotional memories whereas younger adults' angry memories did not show this same pattern. These results are discussed within the context of socioemotional selectivity theory.     

The more you play,the more aggressive you become: A long-term experimental study of cumulative violent video game effects on hostile expectations and aggressive behavior

It is well established that violent video games increase aggression. There is a stronger evidence of short-term violent video game effects than of long-term effects. The present experiment tests the cumulative long-term effects of violent video games on hostile expectations and aggressive behavior over three consecutive days. Participants (N = 70) played violent or nonviolent video games 20 min a day for three consecutive days. After gameplay, participants could blast a confederate with loud unpleasant noise through headphones (the aggression measure). As a potential causal mechanism, we measured hostile expectations. Participants read ambiguous story stems about potential interpersonal conflicts, and listed what they thought the main characters would do or say, think, and feel as the story continued. As expected, aggressive behavior and hostile expectations increased over days for violent game players, but not for nonviolent video game players, and the increase in aggressive behavior was partially due to hostile expectations.     

Children’s mental health: Time to stop using psychiatric diagnosis

Hegemonic mental health service approaches stress the need for ‘accurate’ diagnosis in order to understand what the correct ‘treatment’ should be. I review the evidence on how far diagnosis in psychiatry has helped advance scientific knowledge and clinical practice and conclude that it hasn’t. I then examine how National Institute for Health and Care Excellence (NICE) guidelines in relation to children’s behaviour problems reflects the lack of progress that results from adopting a diagnostic approach. Taking mental health practice beyond reliance on narrow non-evidence-based diagnostic algorithms can be developed by adopting existing projects such as the Partners for Change Outcome Management Systems project.     

The role of peer groups in male and female adolescents' task values and physical activity

The purpose of this longitudinal study was to examine the role of peer groups and sex in adolescents' task values and physical activity. The participants were 330 Finnish Grade 6 students (173 girls, 157 boys), who responded to questionnaires that assessed physical education task values during the spring semester (Time 1). Students' physical activity was assessed one year later (Time 2). The results indicated that adolescent peer groups were moderately homogeneous in terms of task values toward physical education and physical activity. Girls' peer groups were more homogeneous than those of boys in regards to utility and attainment values. Furthermore, the results for both girls and boys showed that particularly intrinsic task value typical for the peer group predicted group members' physical activity. The findings highlight the important role of peer group membership as a determinant of future physical activity.     

The importance of challenge for the enjoyment of intrinsically motivated, goal-directed activities

Although early interview-based analyses of the enjoyment of intrinsically motivated, goal-directed activities (e.g., chess, rock climbing, art making) suggested the importance of relatively difficult, "optimal" challenges, subsequent findings derived from a wider range of activities have not provided consistent support for this proposition. Two studies were conducted to clarify the relation between challenge and enjoyment. Study 1 focused on a single activity-Internet chess. The importance of challenge was evident at the subjective level (perceived challenge strongly predicted enjoyment) as well as the objective level (games against superior opponents were more enjoyable than games against inferior opponents, and close games were more enjoyable than blowouts). In Study 2, the experience sampling method was used to examine the enjoyment of challenge across a wide range of everyday activities. Activity motivation (intrinsically motivated, non-intrinsically motivated) and activity type (goal directed, non-goal directed) moderated the relation. Implications for theories of intrinsic motivation are discussed.     

Cognition and lobar morphology in full mutation boys with fragile X syndrome

The aims of the present study are twofold: (1) to examine cortical morphology (CM) associated with alterations in cognition in fragile X syndrome (FXS); (2) to characterize the CM profile of FXS versus FXS with an autism diagnosis (FXS + Aut) as a preliminary attempt to further elucidate the behavioral distinctions between the two sub-groups. We used anatomical magnetic resonance imaging surface-based morphometry in 21 male children (FXS N = 11 and age [2.27-13.3] matched controls [C] N = 10). We found (1) increased whole hemispheric and lobar cortical volume, cortical thickness and cortical complexity bilaterally, yet insignificant changes in hemispheric surface area and gyrification index in FXS compared to C; (2) linear regression analyses revealed significant negative correlations between CM and cognition; (3) significant CM differences between FXS and FXS + Aut associated with their distinctive behavioral phenotypes. These findings are critical in understanding the neuropathophysiology of one of the most common intellectual deficiency syndromes associated with altered cognition as they provide human in vivo information about genetic control of CM and cognition.     

How the Future Orientation of Traditional Israeli Palestinian Girls Links Beliefs About Women's Roles and Academic Achievement

A model in which future orientation links perceived fathers' and girls' beliefs about traditional women's roles and academic achievement was tested on data collected from traditional Israeli Palestinian girls  ( N = 295)  attending a Moslem all-girl senior high school. LISREL analyses estimated two empirical models pertaining to educational and family future orientation. The estimated models showed that fathers' perceived beliefs were directly linked to academic achievement and future orientation partially mediated the relationships between girls' beliefs about women's roles and academic achievement. Girls' beliefs were negatively linked to the educational future orientation and positively linked to the family future orientation, and the educational model explained a larger percent of the variance of academic achievement than did the family model.
