Learning to learn: From within-modality to cross-modality transfer during infancy

One critical aspect of learning is the ability to apply learned knowledge to new situations. This ability to transfer is often limited, and its development is not well understood. The current research investigated the development of transfer between 8 and 16 months of age. In Experiment 1, 8- and 16-month-olds (who were established to have a preference to the beginning of a visual sequence) were trained to attend to the end of a sequence. They were then tested on novel visual sequences. Results indicated transfer of learning, with both groups changing baseline preferences as a result of training. In Experiment 2, participants were trained to attend to the end of a visual sequence and were then tested on an auditory sequence. Unlike Experiment 1, only older participants exhibited transfer of learning by changing baseline preferences. These findings suggest that the generalization of learning becomes broader with development, with transfer across modalities developing later than transfer within a modality.     

Emotional intelligence and health‐related quality of life in institutionalised Spanish older adults

This study explores the relationship between emotional intelligence (EI) and health‐related quality of life (HRQoL) in a sample of Spanish older adults who are institutionalised in long‐term care (LTC) facilities. One hundred fifteen institutionalised individuals (47.82% women; 88.3 ± 7.9 years) from southern Spain completed a set of questionnaires that included measures of EI, health and personality. Data were analysed via hierarchical regression. After controlling for personality and sociodemographic variables, the EI dimensions, emotional comprehension and emotional facilitation, accounted for part of the variance in several HRQoL facets. These dimensions could have an important role in the HRQoL of residents in LTC. Moreover, the use of a performance measure addresses the limitations of previous studies that have relied on self‐report measures. These aspects underscore the importance of the results of this study.     

Depressive symptoms are associated with unrealistic negative predictions of future life events

This study examined the relationship between depressive symptoms and bias in the prediction of future life events. Responding to internet announcements, 153 participants varying widely in self-reported depression symptom severity estimated the probability of 40 events occurring over the succeeding 30 days. After the 30-day period, participants reported which events occurred. Optimistic/pessimistic biases were related to level of depressive symptoms. A non-significant optimistic bias characterized participants with low depressive symptoms whereas a significant pessimistic bias characterized participants with high depressive symptoms. Those reporting mild symptoms did not exhibit a systematic pessimistic or optimistic bias. General imprecision in predictions for undesirable events was associated with depressive symptoms. These findings suggest that depression is associated with pessimistic bias rather than accuracy in judgment.     

Perceived emotional intelligence and its relationship with perceptions of effectiveness in negotiation

In this study, we examined possible connections between perceived emotional intelligence (PEI) and effectiveness during the negotiation process in a sample of 123 workers from different organizations. Participants completed a set of questionnaires, including an exploration of the predictive and incremental validity of PEI measured by Trait‐Meta‐Mood Scale. Moreover, personality traits were carefully controlled to test the percentage of variance that PEI accounted for in efficiency during negotiation. Multiple regression analyses revealed that emotional repair accounts for part of the variance in the balance of power and in procedural flexibility that cannot be explained by personality traits alone. Thus, our results show that emotional repair accounts for negotiation effectiveness in a way that is independent of personality traits.     

Directional Variability of the Isometric Force Vector Produced by the Human Hand in Multijoint Planar Tasks

Numerous studies have examined control of force magnitude, but relatively little research has considered force direction control. The subjects applied isometric forces to a handle and the authors compared within-trial variability when force is produced in different directions. The standard deviation of the force parallel to the prescribed direction of force production increased linearly with the targeted force level, as did the standard deviation of the force perpendicular to the instructed direction. In contrast, the standard deviation of the angle of force production decreased with increased force level. In the 4 (of 8) instructed force directions where the endpoint force was generated due to a joint torque in only 1 joint (either the shoulder or elbow) the principal component axes in force space were well aligned with the prescribed direction of force production. In the other directions, the variance was approximately equal along the 2 force axes. The variance explained by the first principal component was significantly larger in torque space compared to the force space, and mostly corresponded to positive correlation between the joint torques. Such coordinated changes suggest that the torque variability was mainly due to the variability of the common drive to the muscles serving 2 joints, although this statement needs to be supported by direct studies of muscle activation in the future.     

Are emotional intelligent workers also more empathic?

This paper analyzes whether emotional intelligence and self‐monitoring are related to empathy among a sample of workers in both the public and private employment sectors. Two hundred and forty‐two employees (42.5% men and 57.5% women) with a mean age of 35.21 years (SD = 10.07, range 18–61) completed a questionnaire that measured the variables of interest. The results showed that emotion regulation, a dimension of emotional intelligence, accounts for most of the variance of empathy, followed by the ability to understand emotions and the management of others' emotions. Furthermore, gender did not yield any moderator effect on the relations among emotional intelligence, self‐monitoring and empathy. We conclude that the intrapersonal aspects of emotional intelligence, in particular, emotion regulation, help explain the empathy of workers. The implications of these findings are discussed herein.     

Characterization of PLZT ceramics modified by isovalent (Ba,Sr), donor (Nb) and acceptor (Zn) dopants for piezoelectric applications

This article describes the influence of microstructure on the dielectric and piezoelectric properties of isovalent- donor- and acceptor-modified lead lanthanum zirconium titanate (PLZT) ceramics. The ceramic compositions, with formula: [Pb_0.954La_0.016Ba_0.01Sr_0.02][Zr_0.525Ti_0.475]_{0.981?( m /2)}Nb_0.012Zn _m O₃ where m =?0, 0.2, 0.4, 0.6, 0.8 and 1.0 mol% Zn, were synthesized via a solid-state reaction method. X-ray diffraction studies are supported by tolerance factor and electronegativity difference measurements. Scanning electron microscopy studies reveal grain growth enhancement with increase of Zn concentration. As the Zn concentration increased from 0 to 0.8 mol%, the room-temperature dielectric constant increased while the Curie temperature decreased continuously. An increase in the Zn content had the most significant effect on the piezoelectric properties. The optimum piezoelectric properties were observed for 1 mol% Zn composition.     

Voices of African Traditional Healers: Cultural Context and Implications for the Practice of Counselling in Sub-Saharan Africa

The healing paradigm implicit in many sub-Saharan African cultures is embedded in African cosmology, and thus the recognition of this is essential for understanding Traditional African Healing practices and implementing collaborative counselling practices. To this end, this article focuses on the cultural importance, or voice, of traditional healers in sub-Saharan Africa. The current article uses an ethnographic approach to analyse systematically the cultural context of indigenous healing practices in sub-Saharan Africa. The anthropological importance of Traditional Healing practitioners, the context of healing, and the changing legal and ethical status of Traditional Healers are addressed as pivotal in furthering the development of this crucial, yet under utilized resource. The authors propose that such cultural understanding is highly relevant to the work of professional counselors.     

Addressing Urgent Community Mental Health Needs in Rwanda: Culturally Sensitive Training Interventions

Rwandan leaders in the health and educational sectors have begun to discuss the necessity for establishing culturally appropriate community-based mental health counselling services in Rwanda, especially trauma counselling. The need for a community psychology approach is anchored in the lingering effects of the genocide and the continuing post-traumatic stress symptoms suffered by many in the population. Capacity building in an effort like this would require the design of multi-level counselling curricula that are sensitive to the social structures within Rwandan culture. These curricular endeavours call for the development of a National Counselling Centre to serve as a structural mechanism for organizing community-based counselling initiatives. We consider the community health services needs in Rwanda here, along with associated challenges and strategies for effective mental health services in a country with a recent history of genocide. A community psychology approach to mental health would benefit Rwandan society by making trauma counselling and recovery services available and accessible to citizens throughout the country.
