Alienation and empathy as mediators of the relation between Social Dominance Orientation,Right-Wing Authoritarianism and expressions of racism and sexism

Prior research has established a link between Social Dominance Orientation (SDO), empathy, and generalized measures of prejudice. Whether empathy functions as a mediator for more specific forms of prejudice has not been studied. Furthermore, alienation and its role in predicting prejudice have been given little attention in the literature. Our results found that empathy functioned as a mediator for SDO, but only for sexism, not racism. Alienation was found to act as a mediator between SDO and both racism and sexism. The relation between Right-Wing Authoritarianism and racism and sexism was not mediated by alienation.     

Exposed intestines and contaminated cooks: Sex,stress, & satiation predict disgust sensitivity

An evolutionary perspective predicts that the intensity of the disgust response should depend on the ancestral costs and benefits of coming into contact with disease vectors. Previous research advanced the compensatory behavioral prophylaxis hypothesis: progesterone-induced immunosuppression should be accompanied by increased disgust and contaminant-avoidance. However, extant data do not address whether factors other than progesterone-induced immunosuppression also trigger heightened disgust. The current study delineates two competing prophylaxis hypotheses and adjudicates between them by testing whether stress and satiation, which shift the costs and benefits of prophylactic behavior but are unrelated to progesterone-induced immunosuppression, predict disgust sensitivity. Results revealed a sex–stress–satiation interaction in predicting Disgust Scale-Revised (DS-R) scores. This study provides evidence of a broader system of compensatory prophylaxis, illuminates the functional basis of facultative shifts in disgust, and presents conceptual and statistical analyses for more cleanly cleaving the psychology of disgust at its natural joints.     

Ethical and Legal Considerations for Internet-Based Psychotherapy

The provision of mental health services over the Internet is becoming increasingly commonplace as new technologies continue to develop. Evidence in support of the efficacy of many such interventions is accumulating. Given the potential global reach of Internet-based psychological services, the authors examine ethical issues relating to this growing area of practice through the lens of the Universal Declaration of Ethical Principles for Psychologists (International Union of Psychological Science, 2008). They also raise issues relating to potential liability risks and offer recommendations intended to guide mental health practitioners who are considering involvement in the provision of Internet-based services.     

Mellow Monday and furious Friday: The approach-related link between anger and time representation

Time can be represented spatially in two prevalent metaphors; ego-moving has the self moving “forward” towards the future while time-moving has the future moving “forward” towards the self. Anger also is represented spatially by an approach-related motivation. Because time and anger share an approach-related spatial representation, we hypothesised a link between anger and the ego-moving time perspective. In Study 1, participants naturally adopting an ego-moving representation of time had higher trait anger than those adopting a time-moving representation. Study 2 showed that processing an angry event (vs. an emotionally neutral event) predicted more ego-moving spatial interpretations of time. In Study 3, a scheduling task priming ego-moving (vs. time-moving) time representation prompted higher state anger. Our results reveal a novel bi-directional link between the seemingly unrelated but similarly embodied abstract domains of anger and time.     

Time in the mind: using space to think about time

How do we construct abstract ideas like justice, mathematics, or time-travel? In this paper we investigate whether mental representations that result from physical experience underlie people's more abstract mental representations, using the domains of space and time as a testbed. People often talk about time using spatial language (e.g., a long vacation, a short concert). Do people also think about time using spatial representations, even when they are not using language? Results of six psychophysical experiments revealed that people are unable to ignore irrelevant spatial information when making judgments about duration, but not the converse. This pattern, which is predicted by the asymmetry between space and time in linguistic metaphors, was demonstrated here in tasks that do not involve any linguistic stimuli or responses. These findings provide evidence that the metaphorical relationship between space and time observed in language also exists in our more basic representations of distance and duration. Results suggest that our mental representations of things we can never see or touch may be built, in part, out of representations of physical experiences in perception and motor action.     

Faceted Classification: Management and Use

The paper discusses issues related to the use of faceted classifications in an online environment. The author argues that knowledge organization systems can be fully utilized in information retrieval only if they are exposed and made available for machine processing. The experience with classification automation to date may be used to speed up and ease the conversion of existing faceted schemes or the creation of management tools for new systems. The author suggests that it is possible to agree on a set of functional requirements for supporting faceted classifications online that are equally relevant for the maintenance of classifications, the creation of classification indexing tools, or the management of classifications in an authority file. It is suggested that a set of requirements for analytico-synthetic classifications may be put forward to improve standards for the use and exchange of knowledge organization systems.

Conditioned taste aversion is enhanced when the unconditioned stimulus is presented in a different context

Using a conditioned taste aversion procedure with rats as the subjects, two experiments examined the effect of presenting a conditioned stimulus (CS saccharin solution) in one context followed by an unconditioned stimulus (US LiCl) in a different context. Experiment 1 showed that animals which received the above-mentioned procedure (Group D) showed a more marked conditioned aversion to the CS than animals which were given both the CS and the US in the same context (Group S). Experiment 2 found that in both Group D and Group S, aversion to the CS increased when the subjects were exposed to the conditioned context after the conditioning. These findings supported the argument that the strength of the CS-US association acquired during conditioning is compared with that of the context-US to determine the magnitude of aversion revealed to the CS.     

‘Is’–‘Ought’ Derivations and Ethical Taxonomies

Hume seems to claim that there does not exist a valid argument that has all non-ethical sentences as premises and an ethical sentence as its conclusion. Starting with Prior, a number of counterexamples to this claim have been proposed. Unfortunately, all of these proposals are controversial. Even the most plausible have a premise that seems like it might be an ethical sentence or a conclusion that seems like it might be non-ethical. Since it is difficult to tell whether any of these counterexamples are genuine, we need a taxonomy that sorts out ethical sentences from non-ethical ones. We need to know the difference between an ‘Is’ and an ‘Ought’. In the first part of the paper, I establish the need for a taxonomy. I consider some of the most influential ‘Is’–‘Ought’ derivations. These include proposals by Prior and Searle. I argue that each proposal has a premise whose status as ethical or non-ethical is difficult to determine. In the second part of the paper, I consider taxonomies proposed by Karmo and Maitzen. I argue against both taxonomies. I end with the claim that we need a taxonomy of ethical sentences and that none of the current proposals are adequate.

Congruity Effects in Time and Space: Behavioral and ERP Measures

Two experiments investigated whether motion metaphors for time affected the perception of spatial motion. Participants read sentences either about literal motion through space or metaphorical motion through time written from either the ego-moving or object-moving perspective. Each sentence was followed by a cartoon clip. Smiley-moving clips showed an iconic happy face moving toward a polygon, and shape-moving clips showed a polygon moving toward a happy face. In Experiment 1, using an explicit judgment task, participants judged smiley-moving cartoons as related to ego-moving sentences about space and about time, and shape-moving cartoons as related to object-moving sentences. In Experiment 2, participants viewed the same stimuli, but the cartoons were task-irrelevant. Event-related brain potentials revealed an early attentional effect of congruity on cartoons following sentences about space, and a later semantic effect on cartoons following sentences about time. Results are most consistent with accounts that posit differences in the processing of novel and conventional metaphors.     

Context Effects on Musical Chord Categorization: Different Forms of Top‐Down Feedback in Speech and Music?

A critical issue in perception is the manner in which top-down expectancies guide lower level perceptual processes. In speech, a common paradigm is to construct continua ranging between two phonetic endpoints and to determine how higher level lexical context influences the perceived boundary. We applied this approach to music, presenting participants with major/minor triad continua after brief musical contexts. Two experiments yielded results that differed from classic results in speech perception. In speech, context generally expands the category of the expected stimuli. We found the opposite in music: The major/minor boundary shifted toward the expected category, contracting it. Together, these experiments support the hypothesis that musical expectancy can feed back to affect lower-level perceptual processes. However, it may do so in a way that differs fundamentally from what has been seen in other domains.
