Animal Activists,Civil Disobedience and Global Responses to Transnational Injustice

Traditionally, acts of civil disobedience are understood as a mechanism by which citizens may express dissatisfaction with a law of their country. That expression will typically be morally motivated, non-violent and aimed at changing their government’s policy, practice or law. Building on existing work, in this paper we explore the limits of one well-received definition of civil disobedience by considering the challenging case of the actions of animal activists at sea. Drawing on original interviews with advocates associated with Sea Shepherd, Greenpeace and Humane Society International we find that even if animal activists are morally motivated and civil, the transnational nature of their activity makes it difficult to assess their intention to bring about a change in law or public policy. This means that a civil disobedience defence may not be available to activists operating across international borders. This raises important questions about the usefulness of the civil disobedience concept within the context of a globalised world. We conclude that while the actions of some anti-whaling activists may not meet definitions of civil disobedience as conventionally understood, this says more about the narrow way in which that concept has been traditionally defined, than it does about the type of activity some anti-whaling activists have undertaken in the Southern Ocean. Finally, we argue that activists wishing to make a stand against whaling may have no choice but to act as global citizens because policy change within a single nation-state is unlikely to lead to the cessation of this inherently transnational activity.     

Decoding dyadic interactive nonverbal behaviour in Chinese and Australian cohorts: A novel dyadic puzzle‐solving task

The current study used a novel problem‐solving task in which the solution could only be reached via interactions between members of dyads. The study aimed to systematically examine how nonverbal interactive behaviour was related to the cultural background of the dyads, the participant's role in the dyad (viz., instructor, problem solver) and task repetition. Twenty‐one Australian dyads and 32 Chinese dyads performed the dyadic puzzle‐solving task while their interactions were video‐recorded. In each dyad, one instructor and one problem solver worked together to solve a seven‐piece puzzle. Six trials, each comprising a different puzzle, were completed. Results indicate that the Australian instructors engaged in significantly more eye gazing and displayed more hand gestures but smiled less than the Chinese instructors. The Australian problem solvers maintained longer eye gazing, displayed more hand gestures and more echoing than their Chinese counterparts. Over trials, the Chinese instructors reduced their total talking time, hand gestures, nodding behaviour and smiling during self‐talking more than the Australian instructors. Moreover, the problem solvers in the dyads from both countries significantly reduced their smiling across trials. The current study shows that nonverbal behaviours during dyadic interactions are related to one's cultural background, role in the task and task repetition.     

Effects of body mass index and education on verbal and nonverbal memory

We previously reported that higher education protects against executive dysfunction related to higher body mass index (BMI) in younger, but not older, adults. We now extend the previous analyses to verbal and nonverbal memory. Fifty-nine healthy, dementia-free community-dwelling adults ranging in age from 18 to 81 years completed the Hopkins Verbal Learning Test – Revised (HVLT-R) and the Brief Visuospatial Memory Test – Revised (BVMT-R). Self-reported years of education served as a proxy for cognitive reserve. We found that more highly educated individuals maintained their BVMT-R immediate recall performance across the range of BMI, but in less educated individuals, higher BMI was associated with worse performance. Our findings suggest that education may play a protective role against BMI-related nonverbal learning deficits, similar to previous reports for verbal memory and executive functioning. Results highlight the importance of considering educational background when determining the risk for BMI-related cognitive impairment in clinical settings.     

Post-traumatic Stress Disorder among child perpetrators and victims of violence from the Northern Uganda civil war: Findings from the WAYS study

War experiences are known risk factors for post-traumatic stress disorder (PTSD) and other poor psychosocial outcomes. This study aimed to assess the extent to which perpetrating violence (operationalised as intentional and unintentional killing or mutilation) and being a victim of violence (operationalised as being a victim of violence, e. g., witnessing violence, injuries, torture) predict PTSD and other psychosocial outcomes independently in war-affected youth of Northern Uganda. Data on war experiences, PTSD, psychosocial problems, and socio-demographic characteristics were collected from the youth formerly abducted by the Ugandan Lord’s Resistance Army (LRA) at baseline (mean age = 22.39 years; SD = 10.47) and at follow-up (mean age = 23.52 years; SD = 9.28) using self-report questionnaires. On average, the participants spent 3.13 years in captivity (SD = 2.99) and were abducted at 14.14 years of age (SD = 4.21). Regression models were fitted to predict PTSD and psychosocial outcomes from perpetrating violence controlling for being a victim of violence and demographic characteristics. Thirty-seven percent (n = 168) reported killing or being responsible for killing while in rebel captivity. After adjusting for being a victim of violence, perpetrating violence remained a statistically significant predictor of PTSD and poor psychosocial outcomes such as depression, anxiety, somatic complaints, psychotic symptoms, and conduct problems. Among war-affected youth returning from LRA captivity, perpetrating violence may just be as toxic a risk factor for PTSD and other psychosocial outcomes as being a victim of violence. Mental health workers should consider both the effects of being a victim of violence and perpetrating violence in treatment planning.     

What’s the point? Golden and Labrador retrievers living in kennels do not understand human pointing gestures

In many studies that have investigated whether dogs’ capacities to understand human pointing gestures are aspects of evolutionary or developmental social competences, family-owned dogs have been compared to shelter dogs. However, for most of these studies, the origins of shelter dogs were unknown. Some shelter dogs may have lived with families before entering shelters, and from these past experiences, they may have learned to understand human gestures. Furthermore, there is substantial variation in the methodology and analytic approaches used in such studies (e.g. different pointing protocols, different treatment of trials with no-choice response and indoor vs. outdoor experimental arenas). Such differences in methodologies and analysis techniques used make it difficult to compare results obtained from different studies and may account for the divergent results obtained. We thus attempted to control for several parameters by carrying out a test on dynamic proximal and distal pointing. We studied eleven kennel dogs of known origin that were born and raised in a kennels with limited human interaction. This group was compared to a group of eleven dogs comparable in terms of breed, sex and age that had lived with human families since they were puppies. Our results demonstrate that pet dogs outperform kennel dogs in their comprehension of proximal and distal pointing, regardless of whether trials where no-choice was made were considered as errors or were excluded from statistical analysis, meaning that dogs living in kennels do not understand pointing gestures. Even if genetic effects of the domestication process on human–dog relationships cannot be considered as negligible, our data suggest that dogs need to learn human pointing gestures and thus underscore the importance of ontogenetic processes.     

The effect of bicephalic stimulation of the dorsolateral prefrontal cortex on the attentional bias for threat: A transcranial direct current stimulation study

Previous stimulation studies demonstrated that the dorsolateral prefrontal cortex (DLPFC) is involved in threat processing. According to a model of emotional processing, an unbalance between the two DLPFCs, with a hyperactivation of right frontal areas, is involved in the processing of negative emotions and genesis of anxiety. In the present study, we investigated the role of the right and left DLPFC in threat processing in healthy women who also completed the State-Trait Anxiety Inventory (STAI). We simultaneously modulated the activity of the right and left dorsolateral prefrontal cortex by applying bicephalic transcranial direct current stimulation (tDCS) before participants completed a modified version of the classic Posner task using threatening and nonthreatening stimuli as spatial cues. Anodal stimulation on the right DLPFC with a simultaneous cathodal stimulation over the left side induced a disengagement bias in individuals with low STAI scores and a facilitation bias in individuals with high STAI scores. Anodal stimulation on the left DLPFC with the simultaneous cathodal stimulation over the right side did not affect threat processing. The findings of the present study provided specific support to the hypothesis that unbalanced activation between left and right hemispheres with enhanced activation of the right DLPFC is critical in early top-down threat processing in healthy individuals.     

Using support vector machines to identify literacy skills: Evidence from eye movements

Is inferring readers’ literacy skills possible by analyzing their eye movements during text reading? This study used Support Vector Machines (SVM) to analyze eye movement data from 61 undergraduate students who read a multiple-paragraph, multiple-topic expository text. Forward fixation time, first-pass rereading time, second-pass fixation time, and regression path reading time on different regions of the text were provided as features. The SVM classification algorithm assisted in distinguishing high-literacy-skilled readers from low-literacy-skilled readers with 80.3 % accuracy. Results demonstrate the effectiveness of combining eye tracking and machine learning techniques to detect readers with low literacy skills, and suggest that such approaches can be potentially used in predicting other cognitive abilities.

Technological aids to promote basic developmental achievements by children with multiple disabilities: evaluation of two cases

Technological aids such as microswitches may be critical to foster learning and development in children with multiple disabilities. In study I, a child with minimal motor behavior was provided with a microswitch for chin movements to assess whether he could learn to use these movements to activate environmental stimuli. In study II, a child with dystonic (difficult-to-control) behavior was provided with microswitches for two motor responses and two vocal utterances. We wanted to assess whether he could use both types of responses effectively (varying within each pair, consistent with choice performance). The results were highly encouraging with both children. In study I, there was a significant increase in the childs responding, suggesting learning and contingency awareness. In study II, there was a significant increase in responding as well as response variation that suggested choice behavior. The importance of microswitch devices in promoting new learning/developmental objectives and improving quality of life is discussed.     

Inference suppression and semantic memory retrieval: Every counterexample counts

Reasoning with conditionals involving causal content is known to be affected by retrieval of counterexamples from semantic memory. In this study we examined the characteristics of this search process in everyday conditional reasoning. In Experiment 1 we manipulated the number (zero to four) of explicitly presented counterexamples (alternative causes or disabling conditions) for causal conditionals. In Experiment 2, using a generation pretest, we measured the number of counterexamples participants could retrieve for a set of causal conditionals. One month after the pretest, participants were presented a reasoning task with the same conditionals. The experiments indicated that acceptance of modus ponens linearly decreased with every additionally retrieved disabler, whereas affirmation of the consequent acceptance linearly decreased as a function of the number of retrieved alternatives. Results for denial of the antecedent and modus tollens were less clear. The findings show that the search process does not necessarily stop after retrieval of a single counterexample and that every additional counterexample has an impact on the inference acceptance.
