Mirroring Activity in the Brain and Movement Determinant in the Rorschach Test

Human movement (M) responses to the Rorschach are related to cognitive sophistication, creativity, and empathy. Recent studies also link Ms to EEG-mu suppression, an index of mirroring activity in the brain. In this article, we further investigate the link between Ms and mu suppression by testing some clinical interpretative distinctions. Previously collected EEG data recorded during the administration of the Rorschach were reanalyzed. We hypothesized that (a) among several responses investigated, only M would be associated with mu suppression, and (b) Ms with active movement, ordinary form quality, or whole human figures would be most strongly associated with mu suppression. Hypothesis 1 was fully confirmed, thus supporting that the traditional interpretation of M has a neurobiological foundation. Hypothesis 2 was partially confirmed; that is, active Ms were associated with mu suppression more strongly than passive Ms (p < .05), but no other significant differences emerged. Clinical implications are discussed.     

Comparison of Nomothetic Versus Idiographic-Oriented Methods for Making Predictions About Distal Outcomes From Time Series Data

We illustrate the idiographic/nomothetic debate by comparing 3 approaches to using daily self-report data on affect for predicting relationship quality and breakup. The 3 approaches included (a) the first day in the series of daily data; (b) the mean and variability of the daily series; and (c) parameters from dynamic factor analysis, a statistical model that uses all measurement occasions to estimate the structure and dynamics of the data. Our results indicated that data from the first measurement occasion does not provide information about the couples' relationship quality or breakup 1 to 2 years later. The mean and variability of the time series, however, were more informative: females' average positive and negative affect across time was related to relationship quality, whereas males' variability in negative affect across time was predictive of breakup. The dynamic factor analysis, in turn, allowed us to extract information central to the dyadic dynamics. This information proved useful to predict relationship quality but not breakup. The importance of examining intraindividual variability and couple dynamics is highlighted.     

The Relation Between Mechanical Ability Tests and Verbal and Non-Verbal Intelligence Tests

The present study examined the verbal imitative performance of normal and retarded children at four mental ages (MAs 5, 6, 7, and 8 years). Three dependent measures of imitation were taken: total, mimical, and conceptual. The results indicated that both IQ and mental age were significant factors in imitative performance. Retardates primarily demonstrated mimical imitation at the MA 5 level and conceptual imitation at the MA 7 level, while normals emitted primarily mimical responses at MA7. Retardates and normals differed in total imitation only at MA 5.     

The Relationship between Trauma and Financial and Physical Well-Being Among Cambodians in the United States

This study focused on the relationship between trauma and financial and physical well-being of Cambodian refugees in the United Sates. Trauma was defined by three variables: whether or not trauma had been experienced in Cambodia, the number of traumas experienced, and the number of years spent in refugee camps. It was hypothesized that these trauma variables would predict financial and physical health among Cambodians in the United States. A discriminant analysis showed significant relationships between the trauma variables and current employment status, and multiple regression analyses showed that trauma predicted income and physical health.     

Energetic Cost and Stability during Human Walking at the Preferred Stride Frequency

The possibility that preferred modes of locomotion emerge from dynamical and optimality constraints and the energetic and dynamical constraints on preferred and predicted walking frequency are explored in this article. Participants were required to walk on a treadmill at their preferred frequency, at a frequency predicted as the resonance of a hybrid pendulum-spring model of the legs, and at frequencies ±15%, ±25%, ±35% of the predicted frequency. Walking at the preferred and predicted frequencies resulted in minimal metabolic costs and maximal stability of the head and joint actions. Mechanical energy conservation was constant across conditions. The head was more stable than the joints. The joints appeared to be in service of the head in maintaining a stable trajectory. The major findings of this study suggest a complementary relationship between energetic (physiological) and stability constraints in the adoption of a preferred frequency of walking. Multiple subsystems may be involved in constraining observed macroscopic behavior in intact biological systems. The approach and results of the study imply that a useful tack in understanding how dynamical control structures arise is to study the potential criteria that serve to act as constraints on skilled movement patterns in unimpaired and impaired populations.     

Investigating the interface of the investment model and adult attachment theory

We examined whether the extent to which individuals accord importance to components of the investment model varies by attachment. In Study 1, rewards and costs in a hypothetical relationship were experimentally manipulated, and participants (single and dating undergraduates) reported perceptions of rewards, costs, and satisfaction. In Study 2, investments and alternative quality were manipulated, and participants reported perceptions of investments, alternatives, satisfaction, and commitment. Study 1 revealed that relative to others, individuals high in both anxiety and avoidance (i.e., fearful) accord less weight to rewards when determining satisfaction. Study 2 revealed that relative to others, individuals low in anxiety and high in avoidance (i.e., dismissing) accord more weight to investments and alternatives, and less weight to satisfaction when determining commitment.

Transferring Subcultural Knowledge On-Line: Practices and Beliefs of Persistent Digital Pirates

Criminal subcultures form around deviant behaviors as a consequence of persistent interactions with like-minded others who facilitate the transmission of norms, values, and belief. Although researchers have explored social interactions in the real world, few have considered how learning occurs through virtual interactions. We address the role of on-line interactions in spreading subcultural knowledge by interviewing 34 persistent digital pirates and performing a non-participant ethnography of an on-line forum devoted to piracy. Our results show that through on-line interactions, pirates learn the norms and values of digital piracy, including how to recognize and avoid risks associated with pirating and how to make sense of and justify their actions. They did not see themselves as members of a piracy subculture, however. These findings show that subcultural knowledge can be transmitted through on-line interactions, even when participants do not fully invest in the group.
