Lick-trading by rats: on the substitutability of dry, water, and saccharin tubes.

Thirsty rats licked two metal tubes: a water tube paired with another water tube, with saccharin, or with a dry tube. For each pair, a multipoint baseline function was measured by offering free access to one tube throughout each session, and free or restricted access to the other. The three resulting baseline functions showed the members of each pair to be mutual substitutes: When access to either tube was restricted, the rats made more licks at the other. A linear function identified the two water tubes as perfect substitutes. Convex functions identified the members of the saccharin-water and the dry-water pair as imperfect substitutes. Each pair was also tested under several reciprocal fixed-ratio schedules that required instrumental licking of either tube for contingent access to the other. The resulting schedule functions showed the members of each pair to be perfect substitutes: Water licks decreased linearly as licks at the other water tube, the saccharin, or the dry tube increased, in agreement with a conservation model of instrumental performance. Baseline and schedule functions, indistinguishable in the water-water pair, indicated a schedule facilitation of dry-tube licking in the dry-water pair and of water-tube licking in the saccharin-water pair.     

Morality Predicts Enjoyment But Not Appreciation of Morally Ambiguous Characters

Understanding the role of morally ambiguous characters such as anti-heroes in entertainment experiences has become a central concern for media researchers. Some have argued that different character schemas or tropes may vary along specific moral domains, whereas others promote a linear progression of moral violation from hero to villain. This study presents the results of survey data (N = 294) examining the perceptions of established character tropes in terms of character morality, enjoyment, and appreciation responses. Popular perceptions of character tropes drawn from the website TV Tropes did not significantly differ in terms of which moral domains they upheld or violated, but demonstrated a linear progression of moral violation across five domains of morality. Perceptions of character tropes also did not differ significantly in associations with enjoyment, appreciation, or variables drawn from character identification literature such as self-expansion, wishful identification, or homophily. When examining media responses, however, self-expansion, wishful identification, and moral violation were all strongly related to enjoyment. Unlike enjoyment, appreciation was not related to moral violation. These results are discussed in terms of hedonic and eudaimonic responses to characters.     

Development of a Unified Protocol for the Treatment of Emotional Disorders in Youth

This study evaluated the efficacy of the Mind Reading interactive computer software to remediate emotion recognition deficits in children with autism spectrum disorders (ASD). Six unmedicated children with ASD and 11 unmedicated non-clinical control subjects participated in the study. The clinical sample used the software for five sessions. The control sample was evaluated only on pre- and post-test performance to assess practice effects. Results showed that participants with ASD scored significantly higher on the posttest than on the pretest. As level of emotion difficulty increased, mean scores on the pretest decreased, indicating that difficulty level had a valid effect. The Mind Reading computer software appears to significantly improve the emotion recognition abilities in children with ASD.     

Psychometric analysis of the Empathy Quotient (EQ)

This study assessed the dimensionality of the Empathy Quotient (EQ) using two statistical approaches: Rasch and Confirmatory Factor Analysis (CFA). Participants included N = 658 with an autism spectrum condition diagnosis (ASC), N = 1375 family members of this group, and N = 3344 typical controls. Data were applied to the Rasch model (Rating Scale) using WINSTEPS. The Rasch model explained 83% of the variance. Reliability estimates were greater than .90. Analysis of differential item functioning (DIF) demonstrated item invariance between the sexes. Principal Components Analysis (PCA) of the residual factor showed separation into Agree and Disagree response subgroups. CFA suggested that 26-item model with response factors had the best fit statistics (RMSEA.05, CFI .93). A shorter 15-item three-factor model had an omega (ω) of .779, suggesting a hierarchical factor of empathy underlies these sub-factors. The EQ is an appropriate measure of the construct of empathy and can be measured along a single dimension.     

LOCAL AND GLOBAL PROCESSES IN VISUAL COMPLETION

In the natural environment, objects are frequently occluded, and people continuously complete partly occluded objects Do local processes or global processes control the completion of partly occluded objects? To answer this question, most previous studies simply asked subjects to draw the completions they "saw" Such drawing tasks are highly subjective, and they provide equivocal results Our studies are the first to use an objective, implicit paradigm (primed matching) to determine the extent to which local or global processes underlie the visual completion of partly occluded objects Our results suggest that global processes dominate perceptual completion, whereas local processes do not play a large role Therefore, local theories of completion, or theories in which local processes dominate, cannot be entirely correct
