Elephant psychology: What we know and what we would like to know

Although elephants are well-known and one of the most popular species among people, their behavior and cognitive abilities have not been studied very extensively. But recently, more and more researchers are becoming interested in studying their cognition, particularly their general intelligence, including causal reasoning and mirror self recognition, memory, and numerical cognition. Although genetically elephants are more closely related to the small-brained aardvarks and manatees than to primates, they hold enormous potential in their cognitive skills. Also, studying their cognition is important from the point of view of animal welfare in captivity.     

Self,other and individuation: resolving narcissism through the lunar and solar paths of the Rosarium

This paper describes narcissism as our natural, infant-like behaviour, and specifies three characteristics relating to the evacuation and avoidance of distress, to control, and to distancing from relationship. It suggests that the processes of incarnation and individuation represent the development of the early ego and the ‘resolution’ of these narcissistic ways of being, including escape from the ‘mirror trap’. The development of the early, controlling ‘homunculus-ego’ entails the loosening and broadening of ego-identifications and the ego becoming subject to the Self. This is an embodied-relational-social-spiritual process outlined in detail by the full 20 woodcuts of the Rosarium Philosophorum, and specifically the lunar (relational) and solar (self-expressive) paths, which are explored herein. These processes are illustrated with respect to the interaction between infant and caregiver, clinical vignettes and examples from the political sphere.     

Models that allow us to perceive the world more accurately also allow us to remember past events more accurately via differentiation

Differentiation is a theory that originally emerged from the perception literature and proposes that with experience, the representation of stimuli becomes more distinct from or less similar to the representation of other stimuli. In recent years, the role of differentiation has played a critical role in models of memory. Differentiation mechanisms have been implemented in episodic memory models by assuming that information about new experiences with a stimulus in a particular context accumulates in a single memory trace and these updated memory traces become more distinct from the representations of other stimuli. A key implication of such models is that well encoded events are less confusable with other events. This prediction is particularly relevant for two important phenomena. One is the role of encoding strength on memory. The strength based mirror effect is the finding of higher hit rates and lower false alarm rates for a list composed of all strongly encoded items compared to a list composed of all weakly encoded items. The other is output interference, the finding that accuracy decreases across a series of test trials. Results from four experiments show a tight coupling between these two empirical phenomena such that strongly encoded target items are less prone to interference. By proposing a process model and evaluating the predictions of the model, we show how a single theoretical principle, differentiation, provides a unified explanation for these effects.     

视觉显示技术的新视角：交互显示

交互显示技术是近年人机界面显示技术中形成的一种新型显示技术。这种技术能根据用户的即时输入或操作特点改变初始界面中的显示内容或方式。交互显示技术可分为简单交互显示技术，如鱼眼技术及其应用，和智能交互显示技术，如速率耦合平滑技术，目标气泡技术等。目前的交互显示技术具有动态性、即时性和智能性等特点，但仍存在如交互方式单一，智能性不高等问题，未来研究需强调显示内容变化、交互形式的多样性及其高级智能交互技术等方面的研究。     

Comparison of upright and flipped spoon presentations to guide treatment of food refusal

The current study examined the effects of bite placement with a flipped versus upright spoon on expulsion and mouth clean (product measure of swallowing) in the treatment of 3 children diagnosed with a pediatric feeding disorder and oral-motor deficits. For all 3 participants, extinction in the form of nonremoval of the spoon led to improvements in inappropriate mealtime behavior and acceptance of bites; however, re-presentation did not reduce expulsion or improve mouth clean. Results showed a lower level of expulsion and higher percentage of mouth clean during flipped spoon presentations and re-presentations for all participants. Findings from follow-up analyses supported transitioning back to an upright spoon in all 3 cases, although the time required for this to occur differed across participants.     

Matching the graphical display of data to avoidance versus approach motivation increases outcome expectancies

This study is the first demonstration of the effect of motivational focus (approach vs. avoidance) on the interpretation of graphical view of personal data, specifically, weight loss progress. In two experiments, participants were randomly assigned to see the bogus weight loss data charted against either a goal or a baseline reference line. In the first experiment, we accessed participants' chronic motivational focus. In the second study, we primed motivation by exposing the participants to either a gain- or loss-focused health message. The results demonstrate that participants with either chronic or manipulated approach motivation predicted higher future weight loss in the goal reference line condition than in the baseline reference line condition. The opposite pattern was observed for participants with either chronic or manipulated avoidance motivation. The potential of matching graphical data display to personality characteristics to promote effective health management is discussed.     

Hume on presentation and philosophy

Most philosophers agree that an argument's presentation is relevant to its philosophical merit. This paper explains why David Hume considered presentation philosophically important. On Hume's epistemology, presentation is closely connected with two principal aims of philosophical arguments: persuasion and epistemic justification. Hume's views imply that presentation is a factor determining an argument's persuasiveness and that, by philosophical standards of justification, presentation is also a factor determining the extent to which an argument's conclusion is justified.     

Seeing and being seen in the experience of the client and the therapist

There is more to non-verbal communication than observing the client, although intense observation of the client has taken second place to listening to their words. After reflecting on the history of the use of sight in medicine and psychoanalysis, the author examines the significance for Freud and others of the ‘senses at a distance' (hearing and sight), and issues such as voyeurism and exhibitionism in the therapeutic relationship. The phenomenon of seeing and being seen is related through case examples to issues about distance and space, paranoid anxiety and communication disorders. Attention is also paid to illusion as a way of seeing, and its relevance in the counter-transference. The article concludes by looking at the way clients see therapists, tracing briefly the progression from self-pre-occupation to seeing the therapist as a separate other.     

The Limits of Attention for Visual Perception and Action in Aging

ABSTRACT

This study aimed to investigate whether aging results in an increased attentional blink effect in older adults as compared to young adults. A rapid serial visual presentation (RSVP) paradigm was employed in which participants were asked to identify two targets (dual-task condition) presented in rapid succession. These targets were separated by various intervals in a stream of stimuli. The performance for identifying the second target was normally diminished as compared to identification of a single-task target. Various combinations of tasks, such as two perceptual tasks or one perceptual and one action task, as well as different types of pointing action, such as pointing to a displaced target, pointing to a stationary target or pointing to a disappeared target, were manipulated in this study to see if aging may further impact these variables. The results of this study showed that in young adults, successful identification of the first target interfered with identifying the second target, as well as the initiation time (action planning) of pointing to the second target. However, identification of the first target did not interfere with pointing movement time and pointing accuracy, even when the target was displaced, which required online control of action. Conversely, for older adults, successful central identification not only interfered with identifying the second target and with the pointing initiation time, but also interfered with pointing movement time for a displaced target. This suggests that older adults seem to be unable to concurrently identify the first target and correct their already-initiated pointing movement compared to young adults.     

数目及其呈现方式在不同范围内对时间知觉的影响

采用时间比较法,考察数目及其呈现方式对时间知觉的影响。任务中,首先呈现标准时距,此时变化刺激的数目或呈现方式,然后呈现比较时距,被试的任务是判断比较时距比标准时距长还是短。实验1和实验2分别采用1秒内和1秒以上的时间,结果发现： 1秒内的时间加工中,刺激一个一个连续呈现时,小数引起标准时距的低估,大数导致标准时距的高估,而同时呈现时,刺激的数目对知觉到的时间无影响;数目及其呈现方式影响计时的准确性,而对计时的变异性和敏感性无影响。时间在1秒以上,同时呈现和连续呈现条件下,刺激的数目影响知觉到的时间;计时的
