Reflection without Rules offers a comprehensive, pointed exploration of the methodological tradition in economics and the breakdown of the received view within the philosophy of science. Professor Hands investigates economists' use of naturalistic and sociological paradigms to model economic phenomena and assesses the roles of pragmatism, discourse, and situatedness in discussions of economic practice before turning to a systematic exploration of more recent developments in economic methodology. The treatment emphasizes the changes taking place in science theory and its relationship to (...) the movement away from a rules-based view of economic methodology. The work will be of interest to all economists concerned with methodological issues as well as philosophers and others studying the relationships between economics and contemporary science theory.

After years of progress in terms of gender and sexual rights, since 2012 Europe is facing a so-called gender backlash – opposition directed to issues related to reproductive policies and abortion, violence against women, lesbian, gay, bisexual, transgender, intersex, and queer (LGBTIQ) rights and gay marriages, gender mainstreaming and sex education at schools as well as antidiscrimination policies. In this article, firstly, by taking the anti-gender developments as point of reference, I examine the emergence of anti-gender movement in Europe (...) via the use of what I call troll science. Troll science is based on (distorted) scientific arguments moulded into populist discourse, creating an alternative narrative on the conceptions of gender equality. Similar to troll accounts posting provocative, superfluous and even off-topic messages on social media to start arguments and quarrels aiming to distract, troll science, I argue, creates an alternative narrative opposing the scientific facts and discourses (i.e. climate change, evolution, vaccination and gender theory). Later, I discuss the emerging conservative troll-scientific discourses and the gendered public normative order of Adalet ve Kalkinma Partisi (AKP; Justice and Development Party) government, under the New Turkey. I previously argued that New Turkey and the society under the party’s rule perpetuated by a new set of standards create an alternative narrative on the conceptions of gender equality through troll-science narratives. I concluded by showing how such ideological discourses help create emotional echo chambers – enabling its fast distribution and acceptance by the ideologically conservative groups. Contribution: This paper contributes to the Special Collection Gender Justice, Health and Human Development with the theory of troll-science it introduces to discuss the alternative and anti-gender scientific discourse that is dominating academia.

This article focuses on the resurgence of women’s movements in Turkey and Norway against the backdrop of their historical trajectories and wider gender policies. Throughout the 2010s, both countries witnessed a similar set of conservative and neoliberal policies that intervened in women’s bodily rights. In both countries, women’s movements responded with mass mobilizations and influenced the political agenda. The proposed restrictions on abortion were interpreted as a restriction on women’s basic bodily rights in both countries. This article argues that a (...) feminist, multidimensional reconceptualization of the concept of citizenship and a definition of abortion as an element of women’s bodily citizenship rights are useful to promote a strong and encompassing argument for mobilization. The comparative analysis shows that the right to control one’s own body has been a unifying issue for women’s movements in Turkey and Norway which are gradually becoming more inclusive. (shrink)

Social change does not occur in the same form and direction in every social structure. In this context, every society experiences the modernization process with its own dynamics. These dynamics started with an intervention either from the top or from outside for the countries that want to be included in the modernization process. Due to the government's modernization initiatives, many differences have been made in the individual and social structure. Because, with the changes in the powers governing the state many (...) times in the short term, the society on the way to modernization has faced a new mentality and modernization steps accordingly. However, this difference has not always been in the way the state predicted and organized it. In this sense, the society sometimes accepted the foreseen change and continued it, and sometimes showed resistance to the change. The failure to legitimize the change successfully in the eyes of the people, however, the fact that it was put to work with various sanctions caused the new norms to not be internalized among the people. The modernization movements that could not be internalized by the society were tried to be applied superficially and formally. However, as a result of the development of information opportunities over time and the convergence of the levels in the state on both political and social planes, modernization has started to take its own motivation from internal processes. Thus, an eclectic culture has emerged between the east and the west, but with its own unique motifs. Individuals who grew up in this line have also applied the patterns of the society while living their own modernization experience. These patterns formed in society have changed the emotional and embarrassment thresholds of individuals. Thus, the sense of control, which started from the outside, descended to the core while human beings were civilized. Based on this background, the aim of our study is to read through clothes, within the scope of Elias' theory of civilization, how the change brought about by Turkish modernization has changed the emotional threshold of a single person in social and individual terms. Literature review was preferred for the progress of the study. The research is limited to dress as a subject. Temporally ıt was limited to the period from the II. Mahmud period to the early Republican period. Thus, the study made inferences about today by going back to the Turkish modernization adventure, which dates back 200 years. The study has been divided into three main parts. While these sections were being presented, the topics were often associated with the "religion" theme. (shrink)

My aim in this paper is to expose a misrepresentation of Jean-Luc Nancy’s ideas on community in the secondary literature. I argue that discussions of Nancy’s work have failed to recognize a transformation that has occurred in his later thought, which distances him from Jacques Derrida. I propose that Nancy’s later work points the way beyond the “persistence of unhappy consciousness” in deconstruction through allowing for the possibility of the creation of a world alternative to globalization. Recognition of this transformation (...) is suggestive for how Nancy’s theoretical framework might be employed in analyses of recent resistance movements. (shrink)

Several visual and emotional processes reflect similar underlying patterns of cortical activation. Characteristic individual perceptual style was measured by lateral attentional errors in a standard visual line-bisecting task. The direction of error indicates a predominance of activation in the contralateral prefrontal cortex. Individual differences in mood were measured by the self-endorsement of emotional adjectives. A total of 27 right-handed adults responded to the trait version of the Positive and Negative Affect Schedule (PANAS). As predicted, rightward errors in visual line bisecting (...) correlated positively and significantly with the Positive Affect subscale. The scale adjectives determined and strong had significant correlations with the visual bisecting measure. The negative affect subscale was correlated with neither the line bisecting measure nor the positive subscale. An extension from trait to state measures tested the self-description of current affect using related synonyms and antonyms in a subset of 22 of the participants. Active, dominant, mighty, powerful, and strong were significantly associated with rightward bisecting errors, whereas passive and cooperative were correlated with errors in the opposite direction. The results were incompatible with the valence model (positive-negative), direction model (approach-withdrawal), and movement model (approach-resistance) of the lateral prefrontal substrate of emotion. The action tendency model (active approach-passive yielding) was supported. (shrink)

In September 2014, students and Hong Kong citizens took to the streets demanding universal suffrage. Cell phones and video cameras in hand, amateur student filmmakers were some of the first to capture the police tear-gassing young people that brought the city to its feet.

Producing content-related gestures has been found to impact students’ learning, whether such gestures are spontaneously generated by the learner in the course of problem-solving, or participants are instructed to pose based on experimenter instructions during problem-solving and word learning. Few studies, however, have investigated the effect of (a) performing instructed gestures while learning concepts or (b) producing gestures without there being an implied connection between the gestures and the concepts being learned. The two studies reported here investigate the impact of (...) instructed hand movements on students’ subsequent understanding of a concept. Students were asked to watch an instructional video—focused on the concept of statistical model—three times. Two experimental groups were given a secondary task to perform while watching the video, which involved moving their hands to mimic the placement and orientation of red rectangular bars overlaid on the video. Students were told that the focus of the study was multitasking, and that the instructed hand movements were unrelated to the material being learned. In the content-match group the placement of the hands reinforced the concept being explained, and in the content-mismatch group it did not. A control group was not asked to perform a secondary task. In both studies, findings indicate that students in the content-match group performed better on the posttest, and showed less variation in performance, than did students in the content-mismatch group, with control students falling in between. Instructed hand movement—even when presented as an unrelated, secondary task—can affect students’ learning of a complex concept. (shrink)

A deep investigation of proprioceptive processes is necessary to understand the relationship between sensory afferent inputs and motor outcomes. In this work, we investigate whether and how perception of wrist position is influenced by the direction along which the movement occurs. Most previous studies have tested Joint Position Sense through 1 degree of freedom wrist movements, such as flexion/extension or radial/ulnar deviation. However, the wrist joint has 3-DoF and many activities of daily living produce combined movements, requiring at least (...) 2-DoF wrist coordination. For this reason, in this study, target positions involved movement directions that combined wrist flexion or extension with radial or ulnar deviation. The chosen task was a robot-aided Joint Position Matching, in which blindfolded participants actively reproduced a previously passively assumed target joint configuration. The JPM performance of 20 healthy participants was quantified through measures of accuracy and precision, in terms of both perceived target direction and distance along each direction of movement. Twelve different directions of movement were selected and both hands tested. The left and right hand led to comparable results, both target extents and directions were differently perceived according to the target direction on the FE/RUD space. Moreover, during 2-DoF combined movements, subjects’ perception of directions was impaired when compared to 1-DoF target movements. In summary, our results showed that human perception of wrist position on the FE/RUD space is symmetric between hands but not isotropic among movement directions. (shrink)

Although mouse‐tracking has been taken as a real‐time window on different aspects of human decision‐making processes, whether purely semantic information affects response conflict at the level of motor output as measured through mouse movements is still unknown. Here, across two experiments, we investigated the effects of semantic knowledge by predicting participants’ performance in a standard keyboard task and in a mouse‐tracking task through distributional semantics, a usage‐based modeling approach to meaning. In Experiment 1, participants were shown word pairs and were (...) required to perform a two‐alternative forced choice task selecting either the more abstract or the more concrete word, using standard keyboard presses. In Experiment 2, participants performed the same task, yet this time response selection was achieved by moving the computer mouse. Results showed that the involvement of semantic components in the task at hand is observable using both standard reaction times (Experiment 1) as well as using indexes extracted from mouse trajectories (Experiment 2). In particular, mouse trajectories reflected the response conflict and its temporal evolution, with a larger deviation for increasing word semantic relatedness. These findings support the validity of mouse‐tracking as a method to detect deep and implicit decision‐making features. Additionally, by demonstrating that a usage‐based model of meaning can account for the different degrees of cognitive conflict associated with task achievement, these findings testify the impact of the human semantic memory on decision‐making processes.

ABSTRACTWe tested the response dynamics of the evaluative priming effect using a mouse tracking procedure that records hand movements during the execution of categorisation tasks. In Experiment 1, when participants performed the evaluative categorisation task but not the non-evaluative semantic categorisation task, their mouse trajectories for evaluatively incongruent trials curved more toward the opposite response than those for evaluatively congruent trials, indicating the emergence of evaluative priming effects based on response competition. In Experiment 2, implementing a task-switching procedure in (...) which evaluative and non-evaluative categorisation tasks were intermixed, we obtained reliable evaluative priming effects in the non-evaluative semantic categorisation task as well as in the evaluative categorisation task when participants assigned attention to the evaluative stimulus dime...

The principal goal of the brain-computer interface is to translate brain signals into meaningful commands to control external devices or neuroprostheses to restore lost functions of patients with severe motor disabilities. The invasive recording of brain signals involves numerous health issues. Therefore, BCIs based on non-invasive recording modalities such as electroencephalography are safer and more comfortable for the patients. The BCI requires reconstructing continuous movement parameters such as position or velocity for practical application of neuroprostheses. The BCI studies in (...) continuous decoding have extensively relied on extracting features from the amplitude of brain signals, whereas the brain connectivity features have rarely been explored. This study aims to investigate the feasibility of using phase-based connectivity features in decoding continuous hand movements from EEG signals. To this end, the EEG data were collected from seven healthy subjects performing a 2D center-out hand movement task in four orthogonal directions. The phase-locking value and magnitude-squared coherence are exploited as connectivity features along with multiple linear regression for decoding hand positions. A brute-force search approach is employed to find the best channel pairs for extracting features related to hand movements. The results reveal that the regression models based on PLV and MSC features achieve the average Pearson correlations of 0.43 ± 0.03 and 0.42 ± 0.06, respectively, between predicted and actual trajectories over all subjects. The delta and alpha band features have the most contribution in regression analysis. The results also demonstrate that both PLV and MSC decoding models lead to superior results on our data compared to two recently proposed feature extraction methods solely based on the amplitude or phase of recording signals. This study verifies the ability of PLV and MSC features in the continuous decoding of hand movements with linear regression. Thus, our findings suggest that extracting features based on brain connectivity can improve the accuracy of trajectory decoder BCIs. (shrink)

Measurements of the dimensionality of chaotic attractors obtained on behavioral data represent the task complexity and also could be hypothesized to reflect the number of synchronized neural groups involved in the generation of the data. The changes in dimensionality for different experimental conditions suggest that limited processing capacity, task complexity, demand, and synchrony in neural firing might be closely related.

The notion that cerebellar cortex geometry may play a unique role in its function is explored by Braitenberg et al. in the form of a new theory about the distribution of cortical activity. The theory makes specific predictions which are not verified by an experimental study of hindlimb movement in the cat.

The lambda model of Feldman & Levin for intentional hand movement is compared with a hemispheric motor model (IIMM). Both models imply similar conclusions independently. This increases the validity of both models.

Brain–machine interfaces are systems that allow the control of a device such as a robot arm through a person’s brain activity; such devices can be used by disabled persons to enhance their life and improve their independence. This paper is an extended version of a work that aims at discriminating between left and right imagined hand movements using a support vector machine classifier to control a robot arm in order to help a person to find an object in the (...) environment. The main focus here is to search for the best features that describe efficiently the electroencephalogram data during such imagined gestures by comparing two feature extraction methods, namely the continuous wavelet transform and the empirical modal decomposition, combined with the principal component analysis that were fed through a linear and radial basis function kernel SVM classifier. The experimental results showed high performance achieving an average accuracy across all the subjects of 92.75% with an RBF kernel SVM classifier using CWT and PCA compared to 80.25% accuracy obtained with EMD and PCA. The proposed system has been implemented and tested using data collected from five male subjects and it enabled the control of the robot arm in the right and the left direction. (shrink)

Research suggests that the reaching hand automatically deviates toward a target that changes location during the reach. In the current study, we investigated whether movement intention can influence the target jump’s impact on the hand. We compared the degree of trajectory deviation to a jumped target under three instruction conditions: GO, in which participants were told to go to the target if it jumped, STOP, in which participants were told to immediately stop their movement if the (...) target jumped, and IGNORE, in which participants were told to ignore the target if it jumped and to continue to its initial location. We observed a reduced response to the jump in the IGNORE condition relative to the other conditions, suggesting that the response to the jump is contingent on the jump being a task-relevant event.

The λ model suggests that detailed kinematics arise from changes in control variables and need not be explicitly planned. However, we have shown that when moving a grasped object, grip force is precisely modulated in phase with acceleration-dependent inertial load. This suggests that the motor system can predict detailed kinematics. This prediction may be based on a forward model of the dynamics of the loaded limb.

We investigated how motor agency in the voluntary control of body movement influences body awareness. In the Rubber Hand Illusion , synchronous tactile stimulation of a rubber hand and the participant’s hand leads to a feeling of the rubber hand being incorporated in the participant’s own body. One quantifiable behavioural correlate of the illusion is an induced shift in the perceived location of the participant’s hand towards the rubber hand. Previous studies showed that (...) the induced changes in body awareness are local and fragmented: the proprioceptive drift is largely restricted to the stimulated finger. In the present study, we investigated whether active and passive movements, rather than tactile stimulation, would lead to similarly fragmented body awareness. Participants watched a projected image of their hand under three conditions: active finger movement, passive finger movement, and tactile stimulation. Visual feedback was either synchronous or asynchronous with respect to stimulation of the hand. A significant overall RHI, defined as greater drifts following synchronous than asynchronous stimulation, was found in all cases. However, the distribution of the RHI across stimulated and non-stimulated fingers depended on the kind of stimulation. Localised proprioceptive drifts, specific to the stimulated finger, were found for tactile and passive stimulation. Conversely, during active movement of a single digit, the proprioceptive drifts were not localised to that digit, but were spread across the whole hand. Whereas a purely proprioceptive sense of body-ownership is local and fragmented, the motor sense of agency integrates distinct body-parts into a coherent, unified awareness of the body. (shrink)

Corporate social responsibility movement against labor abuses has gained momentum globally since the 1990s when many corporations adopted codes of conduct to regulate labor practices in their global supply chains.

Recent research has begun to investigate sensory processing in relation to nonclinical variation in traits associated with the autism spectrum disorders (ASD). We propose that existing accounts of autistic perception can be augmented by considering a role for individual differences in top-down expectations for the precision of sensory input, related to the processing of state-dependent levels of uncertainty. We therefore examined ASD-like traits in relation to the rubber-hand illusion: an experimental paradigm that typically elicits crossmodal integration of visual, tactile, (...) and proprioceptive information in an unusual illusory context. Individuals with higher ASD-like traits showed reduced effects of the rubber-hand illusion on perceived arm position and reach-to-grasp movements, compared to individuals with lower ASD-like traits. These differences occurred despite both groups reporting the typical subjective experience of the illusion concerning visuotactile integration and ownership for the rubber hand. Together these results suggest that the integration of proprioceptive information with cues for arm position derived from the illusory context differs between individuals partly in relation to traits associated with ASD. We suggest that the observed differences in sensory integration can be best explained in terms of differing expectations regarding the precision of sensory estimates in contexts that suggest uncertainty.
