Individual Differences in Diving: Intelligence,Personality, and Underwater Adaptation

Diving is an activity that is carried out in an extreme environment with extraordinary psychophysical demands. It requires the divers to undergo an adaptive process in order to survive, to be able to take advantage of their capabilities, and to achieve an efficient performance. In this ex post facto study, data from a sample of military personnel participating in scuba diving courses (N = 649) were analyzed. Our aim was to verify the role of individual differences in the adaptation to an extreme and hostile environment. The results indicate the existence of psychological variables that differentiate between divers and the general population, those who pass or fail the diving course, and between groups of divers who obtain differential levels of performance in underwater tasks. These findings support that dispositional characteristics have utility for the identification of suitable personnel for professional diving.     

Observed actions affect body-specific associations between space and valence

Right-handers tend to associate “good” with the right side of space and “bad” with the left. This implicit association appears to arise from the way people perform actions, more or less fluently, with their right and left hands. Here we tested whether observing manual actions performed with greater or lesser fluency can affect observers' space–valence associations. In two experiments, we assigned one participant (the actor) to perform a bimanual fine motor task while another participant (the observer) watched. Actors were assigned to wear a ski glove on either the right or left hand, which made performing the actions on this side of space disfluent. In Experiment 1, observers stood behind the actors, sharing their spatial perspective. After motor training, both actors and observers tended to associate “good” with the side of the actors' free hand and “bad” with the side of the gloved hand. To determine whether observers' space–valence associations were computed from their own perspectives or the actors', in Experiment 2 we asked the observer to stand face-to-face with the actor, reversing their spatial perspectives. After motor training, both actors and observers associated “good” with the side of space where disfluent actions had occurred from their own egocentric spatial perspectives; if “good” was associated with the actor's right-hand side it was likely to be associated with the observer's left-hand side. Results show that vicarious experiences of motor fluency can shape valence judgments, and that observers spontaneously encode the locations of fluent and disfluent actions in egocentric spatial coordinates.     

Defining greed

Although greed is both hailed as the motor of economic growth and blamed as the cause of economic crises, very little is known about its psychological underpinnings. Five studies explored lay conceptualizations of greed among US and Dutch participants using a prototype analysis. Study 1 identified features related to greed. Study 2 determined the importance of these features; the most important features were classified as central (e.g., self‐interested, never satisfied), whereas less important features were classified as peripheral (e.g., ambition, addiction). Subsequently, we found that, compared to peripheral features, participants recalled central features better (Study 3), faster (Study 4), and these central features were more present in real‐life episodes of greed (Study 5). These findings provide a better understanding of the elements that make up the experience of greed and provide insights into how greed can be manipulated and measured in future research.     

Contacting a 19 month‐old mute autistic girl: A clinical narrative

Conveying that psychoanalysis offers rich opportunities for the very early treatment of autistic spectrum disorders, this clinical communication unfolds the clinical process of a 19 month‐old ‘shell‐type’ encapsulated mute autistic girl. It details how, in a four‐weekly‐sessions schedule, infant Lila evolved within two years from being emotionally out‐of‐contact to the affective aliveness of oedipal involvement. Following Frances Tustin's emphasis on the analyst's ‘quality of attention’ and Justin Call's advice that in baby–mother interaction the infant is the initiator and the mother is the follower, it is described how the analyst must, amid excruciating non‐response, even‐mindedly sustain her attention in order to meet the child half‐way at those infrequent points where flickers of initiative on her side are adumbrated. This helps attain evanescent ‘moments of contact’ which coalesce later into ‘moments of sharing’, eventually leading to acknowledgment of the analyst's humanness and a receptiveness for to‐and‐fro communication. Thus the ‘primal dialogue’ (Spitz) is reawakened and, by experiencing herself in the mirror of the analyst, the child's sense of I‐ness is reinstated. As evinced by the literature, the mainstream stance rests on systematic early interpretation of the transference, which has in our view strongly deterred progress in the psychoanalytic treatment of autistic spectrum disorders.     

Cardiovascular reactivity in hypertensives: differential effect of expressing and inhibiting emotions during moments of interpersonal stress

This study investigated cardiovascular reactivity of hypertensive adults during periods of emotional stress. Two types of instructions were given at different moments, to the same subject, either to express or to suppress feelings during role-play. Expressing, but not inhibiting, emotions elicited significantly higher reactivity during responding to negative scenes, followed by responding during the positive interactions. Blood pressure increases in both expressing and inhibiting conditions, were also found during the instruction periods. Results indicated that socially demanding situations represent a stressor whose effects may vary depending on whether or not respondents regulate expression of emotions. It is suggested that the difficulty in expressing emotions found in some hypertensive individuals may have the function of controlling or reducing blood pressure reactivity.     

Sex differences in cognition are stable over a 10-year period in adulthood and old age

Sex differences in declarative memory and visuospatial ability are robust in cross-sectional studies. The present longitudinal study examined whether sex differences in cognition were present over a 10-year period, and whether age modified the magnitude of sex differences. Tests assessing episodic and semantic memory, and visuospatial ability were administered to 625 nondemented adults (initially aged 35-80 years), participating in the population-based Betula study at two follow-up occasions. There was stability of sex differences across five age groups and over a 10-year period. Women performed at a higher level than men on episodic recall, face and verbal recognition, and semantic fluency, whereas men performed better than women on a task-assessing, visuospatial ability. Sex differences in cognitive functions are stable over a 10-year period and from 35 to 90 years of age.     

The relation of lifetime cognitive activity and lifetime access to resources to late-life cognitive function in older African Americans

Research in older Caucasians has demonstrated that cognitive activity is related to cognitive function in late adulthood. Knowledge of this association is limited in older minority populations. We examined the relation of cognitive activity and access to cognitive resources, with cognitive function in a group of 108 older African Americans. We constructed two scales to measure the frequency of cognitive activity and the presence of resources that promote cognitive activity during early and late life. Both measures had high internal consistency and the cognitive activity scale had adequate temporal stability over a 4-week interval. In analyses that controlled for age and education, more frequent lifetime cognitive activity was related to current cognitive function, but lifetime cognitive resources only approached significance. The results suggest that both measures are psychometrically sound in a minority population and that lifetime cognitive activity may contribute to current cognitive function in African Americans.
