Motion sickness preceded by unstable displacements of the center of pressure

We exposed standing participants to optic flow in a moving room. Motion sickness was induced by motion that simulated the amplitude and frequency of standing sway. We identified instabilities in displacements of the center of pressure among participants who became sick; these instabilities occurred before the onset of subjective motion sickness symptoms. Postural differences between Sick and Well participants were observed before exposure to the nauseogenic stimulus. During exposure to the nauseogenic stimulus, sway increased for participants who became sick but also for those who did not. However, at every point during exposure sway was greater for participants who became motion sick. The results reveal that motion sickness is preceded by instabilities in displacements of the center of pressure.     

Reach Out and Reduce Prejudice: The Impact of Interpersonal Touch on Intergroup Liking

A brief, casual interpersonal touch results in positive behavior toward the toucher, presumably because touch is a cue to friendship. Research on intergroup contact shows that feelings of friendship toward an individual outgroup member reduce prejudice toward that entire group. Integrating these areas, we examined whether interpersonal touch by an outgroup member could reduce prejudice. In three replications in two studies, interpersonal touch decreased implicit, though not explicit, prejudice toward the toucher's group. Effects of interpersonal touch can extend beyond the toucher to others sharing the toucher's ethnicity, and findings suggest that such effects are automatic and outside conscious awareness.     

Reduction in Memory Specificity Following an Approach/Avoidance Scrambled Sentences Task Relates to Cognitive Avoidant Coping

Overgeneral autobiographical memory (OGM) refers to the tendency to retrieve less specific personal memories. According to the functional avoidance hypothesis, OGM might act as a cognitive strategy to avoid emotionally distressing details of negative memories. In the present study, we investigated the effect of an experimentally induced avoidant state on memory specificity. We primed an avoidant state in half of the participants and an approaching state in the other half by means of a Scrambled Sentences Task (SST). Memory specificity was measured before and after priming. Trait cognitive avoidant coping was assessed prior to the experiment. Analyses indicated that higher trait avoidance was significantly associated with lower memory specificity after the SST and stronger reductions in memory specificity from pre- to post-SST, irrespective of the priming condition. The latter suggests that the SST triggered high avoiders’ avoidance schema in both conditions, possibly because it was experienced as a stressor.

     

Self-Induced Motion Sickness and Body Movement During Passive Restraint

From both direct-realist and motor-theoretic perspectives, the objects of speech perception are construed as articulatory events. We offer the alternative view that it is the auditory properties of phonetic events to which listeners are primarily sensitive. Evidence for this alternative view comes from a variety of sources, including studies of phonetic and phonological universals, comparisons of the perception of speech and nonspeech signals, cross-language perceptual experi- ments, and studies of phonetic categorization by nonhuman animals.     

The Black Man and the Mermaid: Desire and Disruption in the Analytic Relationship

This paper considers the impact of desexualization of the maternal on the development of female sexuality. A “chance encounter” revealing a desire in the female analyst, previously unsuspected, disrupts a female patient's prior sense of homoerotic immersion with the analyst. I argue that a girl's would-be oedipal competition is encased within a patriarchal structuring of sexuality where the mother is rendered solely reproductive and preoedipal, not erotically sexual. I examine the meanings for a patient of internalizing a female figure, her analyst, who is viewed as both maternal and sexual. I suggest that a female sense of genital inadequacy and inferiority may have a component of not being able to link the mother's (and in the transference, the analyst's) use of her genitals with her use of her mind/maternal function. I unfold a thesis regarding maternal desexualization that I believe, given mother–infant symbiosis, has rather extensive applicability, and that can lead to viewing any third party as a “dark” interloper.     

Cultural differences in perceived coherence of the self and ingroup: A Japan–Australia comparison

Past studies have found that East Asians ascribe less consistency to individual selves than Westerners, but ascribe more consistency to social groups than Westerners. Using the concepts of naive dialecticism (i.e. the tendency to tolerate contradiction) and psychological essentialism (i.e. the tendency to attribute a fixed essence to something) as different aspects of consistency perception, we examined patterns of perceived consistency of the self and national ingroup among Japanese and Australians. Compared to Australians, Japanese showed more naive dialecticism and less psychological essentialism for the self; however, this cultural difference was not found for their national ingroups. These findings suggest that lay theories are applied in a domain‐specific manner, and the domains to which they are applied depend on culture.

Assessing learning and memory in pigs

In recent years, there has been a surge of interest in (mini) pigs (Sus scrofa) as species for cognitive research. A major reason for this is their physiological and anatomical similarity with humans. For example, pigs possess a well-developed, large brain. Assessment of the learning and memory functions of pigs is not only relevant to human research but also to animal welfare, given the nature of current farming practices and the demands they make on animal health and behavior. In this article, we review studies of pig cognition, focusing on the underlying processes and mechanisms, with a view to identifying. Our goal is to aid the selection of appropriate cognitive tasks for research into pig cognition. To this end, we formulated several basic criteria for pig cognition tests and then applied these criteria and knowledge about pig-specific sensorimotor abilities and behavior to evaluate the merits, drawbacks, and limitations of the different types of tests used to date. While behavioral studies using (mini) pigs have shown that this species can perform learning and memory tasks, and much has been learned about pig cognition, results have not been replicated or proven replicable because of the lack of validated, translational behavioral paradigms that are specially suited to tap specific aspects of pig cognition. We identified several promising types of tasks for use in studies of pig cognition, such as versatile spatial free-choice type tasks that allow the simultaneous measurement of several behavioral domains. The use of appropriate tasks will facilitate the collection of reliable and valid data on pig cognition.
