Anatomical limitations in mental transformations of body parts

Two experiments investigated whether possible and impossible body postures influence mental rotation processes differently considering that anatomical limitations constrain the way in which subjects perform mental transformations of body parts. In Experiment 1, mental rotation was performed on two stimuli presented simultaneously. Both possible and impossible body postures elicited mental rotation, although the mental rotation rate was slower for impossible postures. In Experiment 2, only one stimulus was presented at a time and subjects decided whether it represented a correct body-part configuration or not. A typical mental rotation function was only present for correct body-part configurations. The results are discussed in terms of the familiarity of the stimuli. Unfamiliar stimuli (physically impossible) are rotated via local representations of their parts, whilst global representations are used for rotating familiar (anatomically correct) stimuli.     

Organizational Commitment in the Military: Application of a Profile Approach

According to the 3-component model of commitment, the individual components of commitment—affective (AC), normative (NC), and continuance (CC)—combine to form profiles, and these profiles have different implications for behavior and well-being. We tested these propositions in a military context and also examined conditions (perceived organizational support, organizational justice, job satisfaction, and satisfaction with leadership) that might contribute to the development of commitment profiles. Latent profile analyses of data from 6,501 respondents to the 2010 Canadian Forces Retention Survey revealed 6 distinct profiles. Personnel with profiles reflecting strong AC and NC reported the most favorable work conditions, stay intentions, and well-being; uncommitted personnel and those with CC-dominant profiles reported the least favorable conditions, were most active in job search activities, and scored highest on anxiety and depression. The value of taking a profile approach, and the implications of managing work conditions to promote optimal profiles, are discussed.     

Engaged,Committed and Helpful Employees: The Role of Psychological Empowerment

Although previous research has been focused on the relationship among personality, empowerment, and outcomes, little is known about the incremental effect of empowerment on positive work outcomes. This article aims at exploring the relation between personality factors (i.e., extraversion and conscientiousness) and positive work outcomes (i.e., work engagement, affective organizational commitment, and organizational citizenship behavior), and at determining the incremental effect of psychological empowerment on these outcomes. A convenience sample from three organizations has been used for data collection (N = 258; 52% women, mean age 38.55 years, SD = 10.21). Hierarchical multiple regressions indicate that personality and psychological empowerment explain a significant amount of the variance in the positive organizational outcomes, and that psychological empowerment has a significant incremental value over demographics and personality for the studied outcomes.     

From Teachers’ Work Engagement to Pupils’ Positive Affect: a Weekly Diary Study on the Role of Pupils’ Autonomous Motivation

Target sparing effects in the attentional blink depend on type of stimulus

In a typical attentional blink (AB) experiment, recognition of the second of two serially presented targets is impaired if it occurs around 200-500 ms after the first. However, recognition for the second item is often intact if the two targets occur consecutively (lag-1 sparing). Recent theories of the AB have placed great emphasis on the presence of lag-1 sparing and protracted sparing effects, where accurate performance is seemingly maintained across three or more targets, provided that they are presented consecutively. Here, we show that the type of stimulus (objects vs. letters) used in rapid serial visual presentation streams has a significant effect on the extent of lag-1 sparing, without a commensurate influence on the AB. In addition, multiple consecutive targets produce strikingly different patterns of sparing for objects and letters. These findings suggest that the processes mediating lag-1 sparing are independent of those underlying the AB.     

The Applied Cognitive Psychology of Attention: A Step Closer to Understanding Magic Tricks

Drawing on psychological science, magic provides a unique perspective on applied cognition. Only sparse systematic research, however, documents the thought processes associated with viewing magic tricks. With responses from over 1000 participants, here, we show how individuals construe a classic magic routine wherein a performer appears to vanish a pen. Thirty‐four percent of participants correctly identified the key moment of the disappearance with only 11% thereof knowing what actions the magician actually performed to achieve the effect. Our collective findings support what magicians have known for a long time: knowing when a critical maneuver occurs hardly reveals the associated modus operandi. In line with a modern theory of attention, we discuss our results and highlight the interaction between the when and where attention modules as a necessary component of applied cognition in ecological settings.

The effects of delay on neonatal retention of habituated head-turning

Recovery of neonatal head orientation following auditory habituation was used to examine the effects of intertrial delay. One of two words served as stimuli with criterion orienting and habituation established before the delay. Fifty-six full-term neonates were assigned randomly to one of four delay groups: 10 (control), 55, 100, or 145 s. The percentage of head-turns toward the sound source (with one turn per trial) for blocks of three trials served as the principal dependent variable. Recovery of localized head-turning increased as length of delay increased, with the 100- and 145-s groups showing greater recovery than the 10- and 55-s groups. Infants presented with control trials systematically turned away from the sound source following habituation. Selective sensory adaptation, spontaneous recovery, and short-term memory interpretations of these data are considered.     

John Dewey and the Development of Education in Russia before 1930 -; Report on a Forgotten Reception

This article explores the kinds of response John Dewey(1859-;1952) received in Russia between 1900 and1930, and the impact he had on the educational debatethere. The study's main findings are: Both before andafter the Socialist October Revolution of 1917, Deweyhad a significant impact on the development of theRussian school system. The ultimate rejection ofDewey's pedagogy towards the end of the 20s was notdue to educational but to political and ideologicalreasons.
