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.     

Source memory that encoding was self-referential: the influence of stimulus characteristics

Decades of research suggest that encoding information with respect to the self improves memory (self-reference effect, SRE) for items (item SRE). The current study focused on how processing information in reference to the self affects source memory for whether an item was self-referentially processed (a source SRE). Participants self-referentially or non-self-referentially encoded words (Experiment 1) or pictures (Experiment 2) that varied in valence (positive, negative, neutral). Relative to non-self-referential processing, self-referential processing enhanced item recognition for all stimulus types (an item SRE), but it only enhanced source memory for positive words (a source SRE). In fact, source memory for negative and neutral pictures was worse for items processed self-referentially than non-self-referentially. Together, the results suggest that item SRE and source SRE (e.g., remembering an item was encoded self-referentially) are not necessarily the same across stimulus types (e.g., words, pictures; positive, negative). While an item SRE may depend on the overall likelihood the item generates any association, the enhancing effects of self-referential processing on source memory for self-referential encoding may depend on how embedded a stimulus becomes in one’s self-schema, and that depends, in part, on the stimulus’ valence and format. Self-relevance ratings during encoding provide converging evidence for this interpretation.     

Hebb repetition effects for non-verbal visual sequences: determinants of sequence acquisition

We report four experiments premised upon the work of Horton et al. [(2008). Hebb repetition effects in visual memory: The roles of verbal rehearsal and distinctiveness. Quarterly Journal of Experimental Psychology, 61(12), 1769–1777] and Page et al. [(2013). Repetition-spacing and item-overlap effects in the Hebb repetition task. Journal of Memory and Language, 69(4), 506–526], and explore conditions under which the visual Hebb repetition effect is observed. Experiment 1 showed that repetition learning is evident when the items comprising the non-repeated (filler) sequences and the repeated (Hebb) sequences are different (no-overlap). However, learning is abolished when the filler and Hebb sequences comprise the same items (full-overlap). Learning of the repeated sequence persisted when repetition spacing was increased to six trials (Experiment 2), consistent with that shown for verbal stimuli (Page et al., 2013). In Experiment 3, it was shown that learning for the repeated sequence is accentuated when the output motor response at test is also repeated for the Hebb sequence, but only under conditions of no-overlap. In Experiment 4, repetition spacing was re-examined with a repeated motor output response (a closer methodological analogue to Page et al., 2013). Under these conditions, the gradient of Hebb repetition learning for six trial repetition intervals was markedly similar to that for three trial intervals. These findings further support the universality of the Hebb repetition effect across memory and are discussed in terms of evidence for amodality within-sequence memory.     

In Search of the Caliphate

“In Search of the Caliphate” discusses the historic split between Sunni and Shi'ite Islams in religious studies textbooks, general reference resources, multi-volume reference works on Islam, and briefly suggests other resources (monographs and articles). In analyzing textbooks, the article uses a template taken from the Encyclopedia of Religion (2005) and looks for the following characteristics in the discussion: the question of authority and succession in Islam after the death of the Prophet Mohammad; esoteric knowledge and the role of the Imam (particularly in Shi'a); the assassination of Husayn (the grandson of Mohammed); and the appearance of the eschatological figure of the Madhi in Twelver Shi'a. “Twelver Shi'ism” is used as a search term to analyze the information in reference works (both general works and those devoted to Islam). The conclusion highlights the challenges in researching this topic in a university library.     

Reduced ADHD symptoms in adults with ADHD after structured skills training group: results from a randomized controlled trial

Objective

Feasibility, acceptability, and efficacy of a Dialectical Behavioral Therapy (DBT) -based method developed in Germany were evaluated in a Swedish outpatient psychiatric context.

Method

Fifty-one adults with ADHD on stable medical treatment or on no medication were randomized to the DBT-based skills training (n = 26) or a parallel loosely structured discussion group (n = 25). Self-rating scales were administered before randomization and after the treatment.

Results

Feasibility and participant satisfaction were good in both groups while skills training was perceived as more logical and effective for ADHD-related problems. The analyses of the individuals who completed the treatment and remained stable with regard to medication (n = 19 in skills training; n = 18 in control group) showed a significant reduction in ADHD symptoms in the skills training group, but not in the control group. No reduction of comorbidity was observed in any of the groups.

Conclusions

The treatment was feasible in an outpatient psychiatric context, well tolerated, and significantly reduced ADHD symptoms in on-treatment individuals who remained stable regarding medication status.     

Bootstrap standard error and confidence intervals for the correlations corrected for indirect range restriction

The standard Pearson correlation coefficient, r, is a biased estimator of the population correlation coefficient, ρ(XY) , when predictor X and criterion Y are indirectly range-restricted by a third variable Z (or S). Two correction algorithms, Thorndike's (1949) Case III, and Schmidt, Oh, and Le's (2006) Case IV, have been proposed to correct for the bias. However, to our knowledge, the two algorithms did not provide a procedure to estimate the associated standard error and confidence intervals. This paper suggests using the bootstrap procedure as an alternative. Two Monte Carlo simulations were conducted to systematically evaluate the empirical performance of the proposed bootstrap procedure. The results indicated that the bootstrap standard error and confidence intervals were generally accurate across simulation conditions (e.g., selection ratio, sample size). The proposed bootstrap procedure can provide a useful alternative for the estimation of the standard error and confidence intervals for the correlation corrected for indirect range restriction.     

Visual statistical learning in the newborn infant

Statistical learning – implicit learning of statistical regularities within sensory input – is a way of acquiring structure within continuous sensory environments. Statistics computation, initially shown to be involved in word segmentation, has been demonstrated to be a general mechanism that operates across domains, across time and space, and across species. Recently, statistical leaning has been reported to be present even at birth when newborns were tested with a speech stream. The aim of the present study was to extend this finding, by investigating whether newborns’ ability to extract statistics operates in multiple modalities, as found for older infants and adults. Using the habituation procedure, two experiments were carried out in which visual sequences were presented. Results demonstrate that statistical learning is a general mechanism that extracts statistics across domain since the onset of sensory experience. Intriguingly, present data reveal that newborn learner’s limited cognitive resources constrain the functioning of statistical learning, narrowing the range of what can be learned.
