Implicit evidence on the dissociation of identity and emotion recognition

Cognitive Processing - Recognition of identity and of emotional facial expressions of individuals are both based on processing of the human face. While most studies show these abilities to be...     

Cross-Cultural Validation of the Rorschach Developmental Index

The Developmental Index (DI) has recently been introduced as a composite Rorschach measure of psychological development and maturation, which can be used both with the Comprehensive System (Exner, 2003), and with the recently developed Rorschach Performance Assessment System (Meyer, Viglione, Mihura, Erard, & Erdberg, 2011). As the DI is new, and its validity has not yet been investigated with independent non-U.S. samples, we tested the correlation between DI and age using 3 relatively large samples, 2 of which were from outside the United States (total N = 902). Other Rorschach variables presumably associated with maturation, such as complexity and productivity, were also investigated. As expected, the DI significantly correlated with age, with small variations across the 3 samples. Importantly, the correlation between DI and age remained statistically significant also after controlling for productivity (i.e., the number of responses) and complexity.     

Using Pictures to Evoke Spiritual feelings in Breast Cancer Patients: Development of a New Paradigm for Neuroimaging Studies

This study was designed to develop and validate a method for enhancing spiritual feelings, particularly in women who have received a diagnosis of breast cancer. The protocol specifically was developed to be used in functional magnetic resonance imaging (fMRI) studies. Eighteen breast cancer survivors rated pictures for their ability to enhance feelings of spirituality, happiness, and sadness. Results indicate that presenting carefully selected pictures with spiritual content (e.g., nature scenes, people engaged in contemplative behaviors) can effectively enhance spiritual feelings among breast cancer survivors. Future fMRI studies will explore the use of the protocol developed in this study for investigating neural activity during spiritual feelings and states.     

Sensori-motor integration during stance: Time adaptation of control mechanisms on adding or removing vision

Sudden addition or removal of visual information can be particularly critical to balance control. The promptness of adaptation of stance control mechanisms is quantified by the latency at which body oscillation and postural muscle activity vary after a shift in visual condition. In the present study, volunteers stood on a force platform with feet parallel or in tandem. Shifts in visual condition were produced by electronic spectacles. Ground reaction force (center of foot pressure, CoP) and EMG of leg postural muscles were acquired, and latency of CoP and EMG changes estimated by t-tests on the averaged traces. Time-to-reach steady-state was estimated by means of an exponential model. On allowing or occluding vision, decrements and increments in CoP position and oscillation occurred within about 2 s. These were preceded by changes in muscle activity, regardless of visual-shift direction, foot position or front or rear leg in tandem. These time intervals were longer than simple reaction-time responses. The time course of recovery to steady-state was about 3 s, shorter for oscillation than position. The capacity of modifying balance control at very short intervals both during quiet standing and under more critical balance conditions speaks in favor of a necessary coupling between vision, postural reference, and postural muscle activity, and of the swiftness of this sensory reweighing process.     

Self-awareness training associated with personality traits and sex: a pilot study

107 volunteers learning Reiki-Do self-awareness techniques participated in this study. Results indicate that personality traits in healthy participants might be affected by specific self-awareness training, such as Reiki-Do, with participants' sex playing an independent role.     

The control of responsiveness in ADHD by catecholamines: evidence for dopaminergic, noradrenergic and interactive roles

We explore the neurobiological bases of attention deficit hyperactivity disorder (ADHD) from the viewpoint of the neurochemistry and psychopharmacology of the catecholamine-based behavioural systems. The contributions of dopamine (DA) and noradrenaline (NA) neurotransmission to the motor and cognitive symptoms of ADHD (e.g. hyperactivity, variable and impulsive responses) are studied in rodent and primate models. These models represent elements of the behavioural units observed in subjects with ADHD clinically, or in laboratory settings (e.g. locomotion, changed sensitivity/responsivity to novelty/reinforcement and measures of executive processing). In particular, the models selected emphasize traits that are strongly influenced by mesocorticolimbic DA in the spontaneously hypertensive (SHR) and the Naples high excitability (NHE) rat lines. In this context, the mode of action of methylphenidate treatment is discussed. We also describe current views on the altered control by mesolimbic catecholamines of appropriate and inappropriate goal-directed behaviour, and the tolerance or intolerance of delayed reinforcement in ADHD children and animal models. Recent insights into the previously underestimated role of the NA system in the control of mesocortical DA function, and the frontal role in processing information are elaborated.
