An Academic and Cultural Transition Course for International Students: Efficacy and SocioEmotional Outcomes

The current study details changes in first-year international undergraduate students’ perceived knowledge of, confidence in, and usefulness of intercultural skills in specific US university contexts after completing a semester-long academic and cultural transition course at a mid-sized private university. Results revealed significant increases in participants’ (n= 42) perceived intercultural competence, perspective shifting, suspending judgment, self-advocacy, and interacting in class with students of other cultures; participants also reported significantly higher campus belonging and social support than a comparison group of students at the university who were not enrolled in the course (n = 32). These findings provide initial evidence for the potential of transition courses to increase intercultural skills and campus belonging for first-year undergraduate international students attending US universities

The placebo effect in the motor domain is differently modulated by the external and internal focus of attention

Among the cognitive strategies that can facilitate motor performance in sport and physical practice, a prominent role is played by the direction of the focus of attention and the placebo effect. Consistent evidence converges in indicating that these two cognitive functions can influence the motor outcome, although no study up-to-now tried to study them together in the motor domain. In this explorative study, we combine for the first time these approaches, by applying a placebo procedure to increase force and by manipulating the focus of attention with explicit verbal instructions. Sixty healthy volunteers were asked to perform abduction movements with the index finger as strongly as possible against a piston and attention could be directed either toward the movements of the finger (internal focus, IF) or toward the movements of the piston (external focus, EF). Participants were randomized in 4 groups: two groups underwent a placebo procedure (Placebo-IF and Placebo-EF), in which an inert treatment was applied on the finger with verbal information on its positive effects on force; two groups underwent a control procedure (Control-IF and Control-EF), in which the same treatment was applied with overt information about its inefficacy. The placebo groups were conditioned about the effects of the treatment with a surreptitious amplification of a visual feedback signalling the level of force. During the whole procedure, we recorded actual force, subjective variables and electromyography from the hand muscles. The Placebo-IF group had higher force levels after the procedure than before, whereas the Placebo-EF group had a decrease of force. Electromyography showed that the Placebo-IF group increased the muscle units recruitment without changing the firing rate. These findings show for the first time that the placebo effect in motor performance can be influenced by the subject\u2019s attentional focus, being enhanced with the internal focus of attention

Stay focused! The effects of internal and external focus of attention on movement automaticity in patients with stroke

Dual-task performance is often impaired after stroke. This may be resolved by enhancing patients' automaticity of movement. This study sets out to test the constrained action hypothesis, which holds that automaticity of movement is enhanced by triggering an external focus (on movement effects), rather than an internal focus (on movement execution). Thirty-nine individuals with chronic, unilateral stroke performed a one-leg-stepping task with both legs in single- and dual-task conditions. Attentional focus was manipulated with instructions. Motor performance (movement speed), movement automaticity (fluency of movement), and dual-task performance (dual-task costs) were assessed. The effects of focus on movement speed, single- and dual-task movement fluency, and dual-task costs were analysed with generalized estimating equations. Results showed that, overall, singletask performance was unaffected by focus (p =.341). Regarding movement fluency, no main effects of focus were found in single- or dual-task conditions (p's ≥.13). However, focus by leg interactions suggested that an external focus reduced movement fluency of the paretic leg compared to an internal focus (single-task conditions: p =.068; dual-task conditions: p =.084). An external focus also tended to result in inferior dual-task performance (β = -2.38, p =.065). Finally, a near-significant interaction (β = 2.36, p =.055) suggested that dual-task performance was more constrained by patients' attentional capacity in external focus conditions. We conclude that, compared to an internal focus, an external focus did not result in more automated movements in chronic stroke patients. Contrary to expectations, trends were found for enhanced automaticity with an internal focus. These findings might be due to patients' strong preference to use an internal focus in daily life. Future work needs to establish the more permanent effects of learning with different attentional foci on re-automating motor control after stroke

Chemical kinetics and dynamics of M+(organic) molecules using single photon initiated dissociative rearrangement reactions (SPIDRR) measurements.

Gas-phase studies are important to many areas of science and technology. The ability to prepare molecular species in an environment devoid of complexities present in the condensed phase allows for high resolution measurement of molecular level details. This is particularly important when studying ion-molecule reactions where transition metals are involved. The open-shell, radical nature of the transition metal in combination with its charge promotes a host of low-energy chemical transformations with multiple reactive pathways open within a few eV of the zero point level of the encounter complex ground state. Moreover, barriers along these pathways are often submerged with respect to the separated reactant limit making both temporal and energetically resolved kinetic measurement challenging. However, it is precisely these qualities of a transition metal cation (a chemically reactive center that mediates low energy chemical transformations) that make it a desired catalytic active site and thus demands high resolution study. To this end, the single photon initiated dissociative rearrangement reaction (SPIDRR) technique was developed. This dissertation details the use of this novel tool toward measurement of the kinetics and dynamics of the Ni+ and Co+ mediated decomposition of several organic molecules. Ab initio quantum chemical calculations were performed to compliment these experimental studies. The potential energy surface has been determined at the DFT level to suggest the mechanistic features that occur during the metal mediated decomposition of an organic molecule. The combination of experiment and theory has permitted a far deeper understanding of the reaction dynamics and has proven integral towards explaining experimental observation. For example, emerging concepts that guide hydrogen transfers on Ni+ centered catalytic reactions have evolved from this synergistic combination
