Lecturers' faces fatigue their students: Face identity aftereffects for dynamic and static faces

Face adaptation has been used as a tool to probe our representations for facial identity. It has also been claimed to play a functional role in face processing, perhaps calibrating the visual system towards encountered faces. However, for this to be so, face aftereffects must be observable following adaptation to ecologically valid moving stimuli, not just after prolonged viewing of static images. We adapted our participants to videos, static image sequences or single images of the faces of lecturers who were personally familiar to them. All three stimulus types produced significant, and equivalent, face identity aftereffects, demonstrating that aftereffects are not confined to static images but can occur after exposure to more naturalistic stimuli. It is also further evidence against explanations of face adaptation effects solely in terms of low-level visual processing.     

Belief revision and uncertain reasoning

When a new piece of information contradicts a currently held belief, one has to modify the set of beliefs in order to restore its consistency. In the case where it is necessary to give up a belief, some of them are less likely to be abandoned than others. The concept of epistemic entrenchment is used by some AI approaches to explain this fact based on formal properties of the belief set (e.g., transitivity). Two experiments were designed to test the hypothesis that contrary to such views, (i) belief is naturally represented by degrees rather than in an all-or-nothing manner, (ii) entrenchment is primarily a matter of content and not only a matter of form, and (iii) consequently prior degree of belief is a powerful factor of change. The two experiments used Elio and Pelletier's (1997) paradigm in which participants were presented with full simple deductive arguments whose conclusion was denied, following which they were asked to decide which premise to revise.     

Solving categorical syllogisms with singular premises

We elaborate on the approach to syllogistic reasoning based on “case identification” (Stenning & Oberlander, 1995 Stenning, K. and Oberlander, J. 1995. A cognitive theory of graphical and linguistic reasoning: Logic and implementation. Cognitive Science, 19: 97–140. [Crossref], [Web of Science ®] , [Google Scholar]; Stenning & Yule, 1997 Stenning, K. and Yule, P. 1997. Image and language in human reasoning: A syllogistic illustration. Cognitive Psychology, 34: 109–159. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). It is shown that this can be viewed as the formalisation of a method of proof that dates back to Aristotle, namely proof by exposition (ecthesis), and that there are traces of this method in the strategies described by a number of psychologists, from Störring (1908 Störring, G. 1908. Experimentelle Untersuchungen über einfache Schlussprozesse [Experimental research on simple inferential processes]. Archiv für die Gesamte Psychologie, 11: 1–127.  [Google Scholar]) to the present day. We hypothesised that by rendering individual cases explicit in the premises, the chance that reasoners would engage in a proof by exposition would be enhanced, and thus performance improved. To do so, we used syllogisms with singular premises (e.g., this X is Y). This resulted in a uniform increase in performance as compared to performance on the associated standard syllogisms. These results cannot be explained by the main theories of syllogistic reasoning in their current state.     

Betting on conditionals

A study is reported testing two hypotheses about a close parallel relation between indicative conditionals, if A then B, and conditional bets, I bet you that if A then B. The first is that both the indicative conditional and the conditional bet are related to the conditional probability, P(B|A). The second is that de Finetti's three-valued truth table has psychological reality for both types of conditional—true, false, or void for indicative conditionals and win, lose, or void for conditional bets. The participants were presented with an array of chips in two different colours and two different shapes, and an indicative conditional or a conditional bet about a random chip. They had to make judgements in two conditions: either about the chances of making the indicative conditional true or false or about the chances of winning or losing the conditional bet. The observed distributions of responses in the two conditions were generally related to the conditional probability, supporting the first hypothesis. In addition, a majority of participants in further conditions chose the third option, “void”, when the antecedent of the conditional was false, supporting the second hypothesis.     

Desistance from intimate partner violence: A critical review

Evidence suggests that a significant proportion of men who have been violent towards their partners desist from such violent behaviors; yet, research examining desistance from intimate partner violence (IPV) is limited. This omission is surprising given that an understanding of desistance processes is required to inform evidence-based IPV interventions. In this critical review of the empirical literature, eligible studies included 15 publications, identified through electronic databases and hand searches of bibliographies that directly investigated the cessation of physical violence against an intimate partner, by heterosexual men. No single theory was identified that explains desistance from IPV. However, empirical studies reveal that the severity and frequency of violence is associated with desistance, with those using moderate levels of violence being more likely to desist than those who engage in severe violence. Typology research suggests differences in individual characteristics (e.g., low psychopathology and impulsivity) can distinguish desisters from persisters. In addition, the nature of the dyad within which the violence occurs is also influential in desistance processes. It is concluded that much more research is needed to inform practice and in particular to examine the role of protective factors in mitigating risk and enabling individuals to desist from IPV.     

A review of young people's vulnerabilities to online grooming

This review explores risk factors that may make a young person vulnerable to being groomed online. Even though research in this area is extremely limited, adolescents appear to be the age group most vulnerable to online grooming. Other vulnerabilities appear to be consistent with those associated with offline sexual abuse. The review suggests that behaviors specific to online grooming include: engaging in risk taking behavior online, high levels of internet access, and lack of parental involvement in the young person's internet use. Vulnerabilities to carry out these types of behavior and be more exposed to the risk of online grooming, are set within the context of the Ecological Model of child protection, consisting of: individual, family, community, and cultural risk factors. Patterns of vulnerability regarding living environment, ethnicity, socioeconomic status, and personality are tentative, but are often interconnected. The more risk taking behaviors the young person carries out, plus greater levels of vulnerability factors, the less resilient they are likely to be towards protecting themselves against online grooming. A protective factor appears to be parental involvement in their child's use of the internet. Therefore, this, in combination with internet safety education at school, is encouraged.     

The way of authenticity and the quest for personal integrity1,2

The author reviews the respective conceptions of authenticity proposed by the existentialist philosophers, Fredrich Nietzsche and Martin Heidegger, each of whom situate it in the inherent difficulty of resisting the herd instinct in one's interpersonal relationships, then sets out to show how, despite the absence of authenticity as a technical term in the psychoanalytic lexicon, the technical principles of psychoanalysis enumerated by Freud are compatible with the views of both Nietzsche and Heidegger. The author then gives examples of other psychoanalytic authors who similarly embrace the spirit of authentic relating in their conception of the clinical situation, including the work of D. W. Winnicott, Wilfred Bion, and Jacques Lacan. The author concludes that in the psychoanalytic context the imposition and experience of suffering are invaluable components of authenticity and therapeutic change.     

Spiritual pathology and religious coping as predictors of forgiveness

Spiritual pathology, religious coping, and dispositional forgiveness were investigated in two studies with graduate students at a Christian university-based seminary. Spiritual pathology was operationalised using measures of spiritual instability and spiritual grandiosity. Study 1 (N?=?194) examined patterns of correlation between positive and negative religious coping items, spiritual pathology, and dispositional forgiveness. Spiritual instability correlated with numerous positive and negative religious coping items while spiritual grandiosity did not. Dispositional forgiveness correlated with more positive than negative religious coping items. Study 2 (N?=?214) tested regression models with these variables. Spiritual grandiosity showed a significant quadratic (concave down) effect in predicting dispositional forgiveness while the linear effect was not significant. A hierarchical regression model showed positive religious coping, spiritual instability, and the quadratic effect for spiritual grandiosity each predicted unique variance in dispositional forgiveness after controlling for spiritual impression management. Negative religious coping was not related to dispositional forgiveness when included with these variables.     

The Development of New Tests of Source Memory and a New Approach to the Testing of Equivalence of Parallel Versions

The principal aim of this study was to develop tests of source memory in both the verbal and visuo-spatial domains, which would be brief and easy to use in clinical and population settings. Source memory, that is, memory for context or attributes, is very vulnerable to the effects of ageing and to the early stages of dementia. Because longitudinal studies of cognitive function, including clinical trials, involve repeat testing, practice effects may hamper interpretation when identical tests are administered on each occasion. Accordingly, we developed parallel versions of each of the source memory tests. Rather than assuming equivalence by design, we tested the parallel versions to determine whether they were in fact equivalent in difficulty. We also explored the use of different analytic approaches to establishing equivalence. We report the results of a study in which we compared within- and between-subject performance on three parallel versions of visuo-spatial and verbal source memory tests, as well as three parallel versions of standard tests of episodic memory (word list recall) and executive function (letter fluency, category fluency, ideational fluency) in a sample of healthy elderly volunteers. Participants were tested on three occasions separated by 1 week, and test versions were counterbalanced across test sessions. We also examined performance in a group of participants tested on one occasion only, with test versions being allocated at random. We found that for a number of tests, versions which were designed to be parallel, failed to produce equivalent performance in our sample. We show how the results of this study may be of general use to researchers wishing to select particular versions of the tests in our battery. We also urge researchers to be cautious when using parallel versions of other tests. The careful matching or random allocation of items to parallel versions of a test is no guarantee that performance on the different versions will be equivalent.     

Parent Education in Youth Sport: A Community Case Study of Parents,Coaches, and Administrators

The present community case study was designed to highlight parent, coach, and administrator perceptions of community-based parent education in a youth sport community in the Rocky Mountain region of the United States. Interviews with parents (n?=?12), coaches (n?=?13), and administrators (n?=?11) were interpreted inductively using constructivist thematic analysis. Nine emergent categories are highlighted, including parents’ sport goals for their children, parents’ involvement in youth sport including impacts of involvement on children, and barriers to implementing parent education, as well as potential content for parent education. A proposed sequential framework informing community-based parent education, as well as suggestions for further action, and study limitations are included.
