Training of fast tapping with reduction of kinaesthetic, tactile, visual and auditory sensations

Five subjects were trained to tap on a light Morse-key during nerve compression block. The training sessions lasted for 40 sec., with a 5 sec. rest after the first 20 sec. work period. The group learning curve reached 89.5 per cent. level of normal performance by the eighth training session. In the ninth, the testing session, subjects tapped with visual and auditory sense reduction superimposed on the kinaesthetic and tactile impariment of the training condition. Performance in the testing session reached 40.9 per cent. of normal.

The sixth subject was trained in the same task as the other five subjects, but the training condition included elimination of cues from all four sensory channels. He reached 79.09 per cent. of his normal tapping performance in the seventh session.

These results show that the motor skill of tapping can be relearned in the absence of kinaesthetic cues. Furthermore when the subject has no conscious knowledge of any peripheral sensory cues connected with the ongoing motor activity, learning can nevertheless take place. These findings lead to the hypothesis, that skilled motor activity can be monitored by central processes alone.

During the training sessions subjects showed a tendency of tapping in groups of gradually increasing length. It is hypothesized that increased number of taps forming a group gives an indication to the possible mode of action of these central processes.     

A neurally plausible parallel distributed processing model of event-related potential word reading data

The Parallel Distributed Processing (PDP) framework has significant potential for producing models of cognitive tasks that approximate how the brain performs the same tasks. To date, however, there has been relatively little contact between PDP modeling and data from cognitive neuroscience. In an attempt to advance the relationship between explicit, computational models and physiological data collected during the performance of cognitive tasks, we developed a PDP model of visual word recognition which simulates key results from the ERP reading literature, while simultaneously being able to successfully perform lexical decision—a benchmark task for reading models. Simulations reveal that the model’s success depends on the implementation of several neurally plausible features in its architecture which are sufficiently domain-general to be relevant to cognitive modeling more generally.     

Pluralism and values in education in Hungary – changes between 1990 and 2012

Value transmission is a fundamental task of schools. However, the question arises as to how far prevailing political and social conditions shape the functioning of a country or a region’s school system. In other words: what effect do they have on the choice of values to be transmitted at schools? Are there any fundamental social values that are shared by different cultures at different times? Are there values that exist independently of social and political systems? These questions have a special relevance in Eastern and Central European countries like Hungary where political and social changes in the twentieth century had a crucial effect on the set of values that were transmitted by the school system. The aim of this study is to describe how the value transmitting role of the Hungarian school system has changed as a consequence of political transformations in recent decades.     

Reacquisition and Transfer of Motor Skills With Sensory Feedback Reduction

Reacquisition and transfer of Morse key tapping and finger circling under total peripheral feedback reduction were investigated. 23 medical students were tested. Kinesthetic and tactile feedback were reduced by compression block. The results showed that tapping performance was reacquired to 56.4% of normal and circling to 26.4% by the tenth preshift trials. Strong positive transfer was found for both tasks in Groups 1 and 2. This positive transfer indicated the existence of central, general programming operations. With trials alternating between the two tasks (Group 3) reacquisition curves followed the preshift trials for tapping and circling, showing absence of adverse emotional influence of the block technique. Marked individual differences in performance in the absence of peripheral information were observed, grouping Ss into two distinct categories.     

Transfer Variables in Tracking Skills

In the present work the effect of two task variables on transfer were studied: shape of the track-circular or triangular; and target speed-constant or variable. One or both of these variables was changed on transfer. Experimental conditions were (a) 10 preshift and 10 post-shift trials, and (b) 20 single-trial alternations of two tasks. 22 groups of 12 Ss each were tested. Condition (a) showed positive transfer with single variable change and zero or negative transfer with simultaneous change in two variables, and condition (b) annulled all transfer effects. Results are discussed in terms of commonality between tasks and receptor and perceptual anticipation.     

It is all in good humor? Examining the impact of salesperson evaluations of leader humor on salesperson job satisfaction and job stress

Abstract

Salesperson job stress and job satisfaction have been identified as critical factors affecting job performance. Academic research suggests that sales managers can influence salesperson job stress and job satisfaction. Interestingly, a review of the sales literature finds very little research on the impact of sales leader humor usage on the stress and satisfaction of salespeople. Consequently, we explore how salespeople’s evaluation of their manager’s use of humor influences their individual levels of job stress and satisfaction. We investigate both the positive and negative roles of humor by analyzing the impact of salesperson evaluations of their managers’ use of affiliative and aggressive humor on their job stress and job satisfaction. Furthermore, we examine the mechanism by which these evaluations affect salesperson stress and satisfaction by identifying two critical mediating variables – social loneliness and willingness to cooperate. Using a sample of 299 professional salespeople, we empirically test this process model to find that affiliative humor usage by sales managers, as evaluated by salespeople, reduces social loneliness and stress for salespeople while also increasing followers’ acceptance of cooperation. Evaluations of aggressive humor, on the other hand, increase stress levels among salespeople. Both social loneliness and acceptance of cooperation, in turn, significantly affect job satisfaction.     

Education for the future: The emerging paradigm of thrivable education

A new education paradigm is emerging to address the need to educate a planetary citizenry under conditions relevant to the living context of our planet. Key to this new paradigm is the emphasis on lifelong learning and empathy-oriented education—both critical ingredients to the transformative role of education for individual and collective thrivability. This article explores the parameters of this role and the indicators that point to its emerging presence in a variety of education contexts, both formal and informal as well as virtual and face-to-face.
