Left inferior frontal cortex can compensate the inhibitory functions of right inferior frontal cortex and pre-supplementary motor area

Right-IFG and pre-SMA are associated with inhibitory responses. We used functional Magnetic Resonance Imaging to explore whether the contralateral homotopic regions can functionally replace them. An adolescent, with an extensive traumatic lesion of the right cerebral hemisphere having occurred 5 years earlier, performed a motor response inhibition task (Go/Nogo), which was properly accomplished and associated to activations in the left-IFC, precuneus and occipital cortex. Such functional remodelling is in line with the theory of ‘near equipotentiality’ of the cerebral hemispheres.     

Professed impressions: What people say about others affects onlookers’ perceptions of speakers’ power and warmth

During a conversation, it is common for a speaker to describe a third-party that the listener does not know. These professed impressions not only shape the listener’s view of the third-party but also affect judgments of the speaker herself. We propose a previously unstudied consequence of professed impressions: judgments of the speaker’s power. In two studies, we find that listeners ascribe more power to speakers who profess impressions focusing on a third-party’s conscientiousness, compared to those focusing on agreeableness. We also replicate previous research showing that speakers saying positive things about third parties are seen as more agreeable than speakers saying negative things. In the second study, we demonstrate that conscientiousness-power effects are mediated by inferences about speakers’ task concerns and positivity-agreeableness effects are mediated by inferences about speakers’ other-enhancing concerns. Finally, we show that judgments of speaker status parallel judgments of agreeableness rather than of power, suggesting that perceivers use different processes to make inferences about status and power. These findings have implications for the literatures on person perception, power, and status.     

Inclined Weight-Loaded Walking at Different Speeds: Pelvis-Shoulder Coordination,Trunk Movements and Cost of Transport

Although studied at level surface, the trunk kinematics and pelvis-shoulder coordination of incline walking are unknown. The aim of this study was to evaluate the speed effects on pelvis-shoulder coordination and trunk movement and the cost of transport (C) during unloaded and loaded (25% of body mass) 15% incline walking. We collected 3-dimensional kinematic and oxygen consumption data from 10 physically active young men. The movements were analyzed in the sagittal plane (inclination and range of trunk motion) and the transverse plane (range of shoulder and pelvic girdle motion and phase difference). The rotational amplitude of the shoulder girdle decreased with load at all speeds, and it was lower at the highest speeds. The rotational amplitude of the pelvic girdle did not change with the different speeds. The phase difference was greater at optimal speed (3 km.hr^?1, at the lowest C) in the loaded and the unloaded conditions. The trunk inclination was greater with load and increased with speed, whereas the range of trunk motion was lower in the loaded condition and decreased with increasing speed. In conclusion, the load decreased the range of girdles and trunk motion, and the pelvis-shoulder coordination seemed to be critical for the incline walking performance.     

Promoting Functional Ambulation with People with Blindness and Multiple Disabilities

An intervention package comprising auditory cues, physical prompts preceded by vibratory (anticipatory) stimuli, and reinforcement was used to promote ambulation to target places with 2 men with total blindness, profound intellectual disability, and behavioural problems. Data showed that both men acquired successful ambulation to the target places, becoming almost totally independent of the physical prompts. Implications of the findings are discussed.     

Coping as a mediator of the impact of sociocultural factors on health behavior among HIV-positive latino gay men

In a sample of 140 HIV-positive immigrant Latino gay men, we tested a mediational model of the impact of sociocultural factors (i.e., poverty, discrimination, and U.S. acculturation) on active engagement of health-promoting behaviors (i.e., practicing good health habits). The role of coping as a mediator was examined. We proposed that the experience of social discrimination, together with acculturation, has a negative influence on active coping, which in turn would impact health behaviors. Regression analyses supported the role of coping as a mediator between sociocultural factors (specifically discrimination based on race or ethnicity and acculturation to the U.S.) and health-promoting behaviors. Findings from this study contribute to explaining the way in which sociocultural factors impact health among those who are HIV-positive and most vulnerable in our society.     

Enforced Disappearances and Torture Today: A View from Analytical Psychology

Enforced disappearance represents the quintessence of human rights violations with a strong psychological component. Bodies vanishing have a deterrent effect by terrorizing and paralyzing the entire society. However, the absence of those bodies is overly present in the inner experience of the families of the disappeared, who are victims in their turn. A state of severe psychological deterioration affects the relatives of the disappeared: depression, anxiety, powerlessness, guilt, post-traumatic stress disorder, inability to mourn, even suicide are the consequences of the unbearable uncertainty about the fate of the loved one. But the disappeared persons, notwithstanding the absence of their bodies, continue to be more present than ever in the inner experience of those who have loved them. For the families of the disappeared, to regain psychological equilibrium is a fine balance between the need to remember and the necessity to forget. The author affirms that, at a social and political level, to cultivate a collective memory of enforced disappearance is an ethical duty which validates the actual occurrence of the atrocities, helps prevent repetition and alleviates the transgenerational transmission of trauma.     

Psychotherapy as religion: Pros and cons

Psychotherapy and religiousness are closely linked without being identical. This theme is explored in the relationship between therapist and client, in a faith development theory, and in feminist perspectives which present potentials for transforming religiousness and psychotherapy. The main critique of psychotherapy as religiousness is its lack of both communal and ecological dimensions.     

Comments on “The Ketamine Model of the Near-Death Experience: A Central Role for the N-Methyl-D-Aspartate Receptor”

Although ketamine can induce a state similar to a near-death experience (NDE), there is a striking difference between experiences induced by ketamine used in a recreational context and in an operating room. Ketamine is a noncompetitive antagonist of the N-methyl-D-aspartate receptor, as is ibogaine, the main alkaloid of a shrub used in Central Africa to induce NDEs in a religious context. Ibogaine can also elicit different experiences when used in a hallucinatory context or in initiatic rituals, where a superficial state of coma is induced. These data raise the question of whether the chemically-induced NDE-like experience is related to the use of a particular kind of substance or to a genuine comatose state.
