What’s up in mental rotation?

We report two experiments on the influence of head tilt on mental rotation. In Experiment I, subjects decided whether dot patterns were or were not repeated about a line. Their reaction times (RTs) were consistent with the interpretation that they mentally rotated the patterns so that the line was subjectively vertical before making their decisions. When the subjects tilted their heads, the RT functions shifted in the direction of the tilt, indicating that the subjective vertical lay closer to the retinal than to the gravitational vertical. In Experiment II, subjects decided whether singly presented alphanumeric characters in various orientations were standard or backward (mirror-reversed). Again, analysis of their RTs suggested mental rotation to the standard upright, but the function was unaffected by head tilt; in this case, the subjects operated in subjective gravitational rather than retinal coordinates. The choice of retinal or gravitational coordinates may depend on whether the stimuli are interpreted egocentrically or as part of the external world.     

Spatial term apprehension with a reference object’s rotation in three-dimensional space

It has been reported that the overall shapes of spatial categorical patterns of projective spatial terms such as above and below are not influenced by the rotation of a reference object on a two-dimensional (2D) upright plane. However, is this also true in three-dimensional (3D) space? This study shows the dynamic aspects of the apprehension of projective spatial terms in 3D space by detailing how the rotation of a reference object with an inherent front influences the apprehension of projective spatial terms on a level plane by mapping their spatial categorical patterns. The experiment was designed to examine how spatial categorical patterns on a level plane changed with the rotation of a reference object with an inherent front in 3D computer graphics space. We manipulated the rotation of a reference object with an inherent front at three levels (0°, 90°, and 180° rotations) and examined how such manipulation changed the overall spatial categorical patterns of four basic Japanese projective spatial terms: mae, ushiro, hidari, and migi (similar to in front of, behind, to the left of, and to the right of in English, respectively). The results show that spatial term apprehension was affected by the rotation of the reference object in 3D space. In particular, rotation influenced the mae–ushiro and hidari–migi systems differently. The results also imply that our understanding of projective spatial terms on a level plane in 3D space is affected dynamically by visual information from 3D cues.     

Motion in the mind’s eye: Comparing mental and visual rotation

Mental rotation is among the most widely studied visuospatial skills in humans. The processes involved in mental rotation have been described as analogous to seeing an object physically rotate. We used functional magnetic resonance imaging of the whole brain and localized motion-sensitive hV5/MT1 to compare brain activation for stimuli when they were mentally or visually rotated. The results provided clear evidence for activation in hV5/MT1 during both mental and visual rotation of figures, with increased activation for larger rotations. Combined with the overall similarities between mental and visual rotation in this study, these results suggest that mental rotation recruits many of the same neural substrates as observing motion.     

Context dependency in Stroop's paradigm: when are words treated as nonlinguistic objects?

The "memory" literature emphasizes the notion of encoding variability, whereas the "word recognition and attention" literature typically asserts that it is impossible to prevent immediate lexical and semantic activation when single words are presented to skilled readers. In the four experiments reported here, the presence/absence of a Stroop effect was associated with the nature of the between-trial context. These data can be understood as an expression of contextually driven encoding variability, but are problematic for the decontextualized "automatic" processing account that has prevailed in the attention and performance literature for the last six decades.     

The role of attention in motion extrapolation: are moving objects 'corrected' or flashed objects attentionally delayed?

Objects flashed in alignment with moving objects appear to lag behind [Nijhawan, 1994 Nature (London) 370 256-257]. Could this 'flash-lag' effect be due to attentional delays in bringing flashed items to perceptual awareness [Titchener, 1908/1973 Lectures on the Elementary Psychology of Feeling and Attention first published 1908 (New York: Macmillan); reprinted 1973 (New York: Arno Press)]? We overtly manipulated attentional allocation in three experiments to address the following questions: Is the flash-lag effect affected when attention is (a) focused on a single event in the presence of multiple events, (b) distributed over multiple events, and (c) diverted from the flashed object? To address the first two questions, five rings, moving along a circular path, were presented while observers attentively tracked one or multiple rings under four conditions: the ring in which the disk was flashed was (i) known or (ii) unknown (randomly selected from the set of five); location of the flashed disk was (i) known or (ii) unknown (randomly selected from ten locations). The third question was investigated by using two moving objects in a cost-benefit cueing paradigm. An arrow cued, with 70% or 80% validity, the position of the flashed object. Observers performed two tasks: (a) reacted as quickly as possible to flash onset; (b) reported the flash-lag effect. We obtained a significant and unaltered flash-lag effect under all the attentional conditions we employed. Furthermore, though reaction times were significantly shorter for validly cued flashes, the flash-lag effect remained uninfluenced by cue validity, indicating that quicker responses to validly cued locations may be due to the shortening of post-perceptual delays in motor responses rather than the perceptual facilitation. We conclude that the computations that give rise to the flash-lag effect are independent of attentional deployment.     

24-Karat or fool’s gold? Consequences of real team and co-acting group membership in healthcare organizations

Although theory on team membership is emerging, limited empirical attention has been paid to the effects of different types of team membership on outcomes. We propose that an important but overlooked distinction is that between membership of real teams and membership of co-acting groups, with the former being characterized by members who report that their teams have shared objectives, and structural interdependence and engage in team reflexivity. We hypothesize that real team membership will be associated with more positive individual- and organizational-level outcomes. These predictions were tested in the English National Health Service, using data from 62,733 respondents from 147 acute hospitals. The results revealed that individuals reporting the characteristics of real team membership, in comparison with those reporting the characteristics of co-acting group membership, witnessed fewer errors and incidents, experienced fewer work related injuries and illness, were less likely to be victims of violence and harassment, and were less likely to intend to leave their current employment. At the organizational level, hospitals with higher proportions of staff reporting the characteristics of real team membership had lower levels of patient mortality and sickness absence. The results suggest the need to clearly delineate real team membership in order to advance scientific understanding of the processes and outcomes of organizational teamwork.     

Sex differences in mental rotation with polygons of different complexity: Do men utilize holistic processes whereas women prefer piecemeal ones?

Sex differences in mental rotation were investigated as a function of stimulus complexity with a sample size of N = 72. Replicating earlier findings with polygons, mental rotation was faster for males than for females, and reaction time increased with more complex polygons. Additionally, sex differences increased for complex polygons. Most importantly, however, mental rotation speed decreased with increasing complexity for women but did not change for men. Thus, the sex effects reflect a difference in strategy, with women mentally rotating the polygons in an analytic, piecemeal fashion and men using a holistic mode of mental rotation.

“It’s like a charge – either fuses you or burns you out”: an interpretative phenomenological analysis of extreme mental states in meditation context

Meditation, an ancient Eastern spiritual practice, is increasingly being practised in the West where its benefits for mental and physical health have been established. Extreme mental states that can be encountered in the context of meditation have also been reported and often have been labelled as psychosis or spiritual emergency. This study aimed for more nuanced understanding of the phenomena. Interpretative phenomenological analysis was employed to explore the meaning-making of three meditation teachers from different philosophical traditions. The teachers described phenomenology of various extreme mental states, explained their nature according to their traditions and discussed ways of helping persons who experience these. Significance was given to having a spiritual teacher to provide guidance and support. The study highlights the importance of acknowledging the diverse understandings of the phenomena and cultivating a non-judgemental attitude towards it, which could help clinicians and meditation teachers work together to support persons experiencing these.     

Does Empathy Have Any Place in Aquinas’s Account of Justice?

Recent developments in cognitive science have prompted philosophers to speculate about the importance of empathy, the ability to directly apprehend and take on the mental and emotional states of others, in understanding and being motivated by moral norms—particularly moral norms concerning other humans. In this paper, I investigate whether some kind of empathy is involved in Thomas Aquinas’s account of the virtue of justice, which he describes as essentially other-directed. I claim that a kind of empathy is involved in Aquinas’s notion of friendship and that this notion of friendship is related to justice as a virtue as its goal. Having the virtue of justice is geared towards establishing true friendship, at least in part. In so doing, it is directed towards establishing a sufficient groundwork for genuine empathy. Instances of genuine empathy, then, are approximations of this goal of the work of justice, even if they occur outside the context of a true friendship. Given this, I describe possible roles Aquinas might afford empathy and empathetic emotions in the context of cultivating the virtue of justice, including roles in motivation and knowledge.     

Does assimilation into schemas involve systems or cellular consolidation? It’s not just time

A comment by Rudy and Sutherland [Rudy, J. R., &; Sutherland, R. J. (2008). Is it systems or cellular consolidation? Time will tell. An alternative interpretation of the Morris Group’s recent Science Paper. Neurobiology of Learning and Memory] has suggested an alternative account of recent findings concerning very rapid systems consolidation as described in a recent paper by Tse et al [Tse, D., Langston, R. F., Kakeyama, M., Bethus, I., Spooner, P. A., &; Wood, E. R., et al. (2007). Schemas and memory consolidation. Science, 316, 76–82]. This is to suppose that excitotoxic lesions of the hippocampus cause transient disruptive neural activity outside the target structure that interferes with cellular consolidation in the cortex. We disagree with this alternative interpretation of our findings and cite relevant data in our original paper indicating why this proposal is unlikely. Various predictions of the two accounts are nonetheless outlined, together with the types of experiments needed to resolve the issue of whether systems consolidation can occur very rapidly when guided by activated neural schemas.     

Does the athletes’ body shape the athletes’ mind? A few ideas on athletes’ mental rotation performance. Commentary on Jansen and Lehmann

Athletes exhibit differences in perceptual-cognitive abilities when compared to non-athletes. Recent theoretical developments focus on the role of the athletes’ body in perceptual-cognitive tasks such as mental rotation tasks. It is assumed that the degree to which stimuli in mental rotation tasks can be embodied facilitates the mental rotation process. The implications of this assumption are discussed and ideas for future research are presented.     

Symbolic analysts or indentured servants? Indian high-tech migrants in America’s information economy

Paula Chakravartty contrasts the everyday experiences of Indian entrepreneurs from Bangalore, who are very successfully developing that region as a high-tech global metropolis, with the often unhappy, mid-level educated Indian migrants to the U.S. who now come to the U.S. on H-1B visas because they were not “good enough” to break into the elite schools and best high-tech operations in India. Because of foreign status, Indian migrants often face “glass ceilings” in professional advancement not commensurate with education, experience or professional attainment, as Chakravartty points out. She maintains that due to the precariousness of the H-1B type immigration status, it can be argued skilled migrants to the U.S. have frequently been exploited by employers, having become the equivalent of “high-tech braceros.” Chakravartty also explores the evolving ties of international students in the U.S. and high-tech workers from India in Silicon Valley that have led to kinds of globally circulating currents of hi-tech labor.

Where’s the difficulty in standardized reading tests: The passage or the question?

The purpose of this investigation was to examine the extent to which item and text characteristics predict item difficulty on the comprehension portion of the Gates-MacGinitie Reading Tests for the 7th–9th and 10th–12th grade levels. Detailed item-based analyses were performed on 192 comprehension questions on the basis of the cognitive processing model framework proposed by Embretson and colleagues (Embretson & Wetzel, 1987). Item difficulty was analyzed in terms of various passage features (e.g., word frequency and number of propositions) and individual-question characteristics (e.g., abstractness and degree of inferential processing), using hierarchical linear modeling. The results indicated that the difficulty of the items in the test for the 7th–9th grade level is primarily influenced by text features—in particular, vocabulary difficulty—whereas the difficulty of the items in the test for the 10th–12th grade level is less systematically influenced by text features.     

Consider Stages of Development in Preventing Terrorism: Does Government Building Fail and Terrorism Result when Developmental Stages of Governance are Skipped?

Countries, governments, and cultures must move through each of the stages of human development (Commons et al. (1998). Developmental Review, 8(3), 237–278) sequentially. Each stage must be achieved, and failure to recognize this may be a major contributing factor to the rise of terrorism and crime in a society. For example, in a war-like situation, an occupying country’s attempts to have the conquered country jump developmental stages will fail more often than not, possibly resulting in negative sentiment and terrorist behavior among those in the occupied country. Although the US is great at winning small wars such as those against Afghanistan, Grenada, Haiti, Iraq, and Panama, it fails at making and maintaining peace and, in turn, creating democracies. This article will address the reasons why this may be, and what can be done to improve upon our current “hit or miss” policies. We will address some of the developmental stages of the tasks of governing, and some of the means by which government activities may move up in stage. Finally, we suggest reasons why the US has had its various successes in preventing or reducing terrorism when it helped itself and other countries move up in stage and failures when it did not, and why governments in general should move up to more complex stages to reduce the number of terrorists generated.     

Sledging in Sport—Playful Banter,or Mean-spirited Insults? A Study of Sledging’s Place in Play

Abstract

Sledging, or ‘trash talk’ or ‘chirping’, as it’s known in other parts of the world, has long been part of competitive sport. However, more recent times have seen the issue of sledging, and its place in sport, debated with many athletes, fans and academics arguing that sledging has moved outside the notion of ‘sportsmanship’ and gone beyond light hearted, good natured banter. They argue it is now characterized as hurtful, insulting, offensive and intimidating – a tactic that has moved beyond fair play and, in many instances, no longer acceptable. This paper seeks to explore this issue in greater depth. In particular, this paper seeks to ask, ‘is sledging part of play, or is it a characteristic of play’s corruption?’ The argument proceeds by adopting a conception of play grounded in the work of Johan Huizinga. Play may be understood as a core component of even professional sport, not least in that play lies at the moral core of the ‘spirit of sport’ in fairplay and respect for one’s opponents. Using examples to illuminate the changing nature of play and sledging, it will be argued that sledging in its modern form leads to the corruption of this ‘spirit of sport’. The insights of sports and philosophy academics and scholars are drawn upon, as are the insights of surveyed sports fans and amateur athletes who highlight their views on sledging and its place in modern sport. By doing so, sledging’s role in sport and its most dominant characteristics, according to those to watch professional sport and play at the community level, become clear, helping to articulate the difference between a form of sledging that is still playful and a part of play, and sledging that is characteristic of play’s corruption.     

Does Government Make People Happy?: Exploring New Research Directions for Government’s Roles in Happiness

Our study aims to explore new directions for researches on government’s role in enhancing quality of life (QOL). Although government can influence, to the greatest extent, people’s happiness, very few studies have systemically examined the quantitative or qualitative attributes of government in happiness enhancement, compared with the large volume of studies on economic, political, and cultural factors’ impact on QOL. Related to government’s role in happiness, we suggest ‘nine new research directions,’ all of which can generally be related with its’ quantitative and qualitative attributes. Even though much existing researches have focused on a part of quantitative sides of government, there are still many remaining attributes to be highlighted. Moreover, we expect that new, composite and nonlinear quality attributes of government will provide bountiful research topics in the future. Also, cross-boundary comparisons and mixtures between quality and quantity, as well as the conditional macro-context for government’s role, suggest new ideas for QOL studies.
