The role of inner and outer face parts in holistic processing: A developmental study

The effects of inner–outer feature interactions with unfamiliar faces were investigated in 6- and 10-year-old children and adults (20–30 years) to determine their contribution in holistic face vision. Participants completed a two-alternative forced-choice (2AFC) task under two conditions. The congruent condition used whole, inner-only, and outer-only stimuli. The incongruent condition used stimuli combining the inner features from one face with outer features from a novel face, or vice versa. Results yielded strong congruency effects which were moderated by pronounced feature-type asymmetries specific to developmental stage. Adults showed an inner-feature preference during congruent trials, but no asymmetry for incongruent trials. Children showed no asymmetry for congruent trials, but an outer-feature preference for incongruent trials. These findings concur with recent theoretical developments indicating that adults and children are likely to differ in the types of feature-specific information they preferentially encode in face perception, and that holistic effects are moderated differently in adults and children as a function of feature type.     

Type II twinning in devitrite,Na2Ca3Si6O16

Nanometre-scale twins found in the triclinic crystalline phase devitrite, Na₂Ca₃Si₆O₁₆, are shown to exhibit the relatively rare form of twinning, Type II twinning, in which the crystal structure of one of the parts is related to the crystal structure of the other by a rotation of 180° about η ₁?=?[1?0?0]. Although formally, the twin plane K ₁ is irrational, it is in essence (0?1?0).     

Adolescents,Risk Behaviour and Confidentiality: When Would Australian Psychologists Breach Confidentiality to Disclose Information to Parents?

The protection of confidentiality in psychological practice is vital. However, confidentiality is not absolute and psychologists are permitted to breach confidentiality under particular circumstances. Ethical challenges surrounding confidentiality are complex with adolescent clients, as assessments often consider the risk that adolescents pose to themselves in addition to the risk posed to others. The current study documented situations in which Australian psychologists would breach adolescents' confidentiality to disclose information about risk behaviour to parents, with a focus on situations where adolescents posed a risk to themselves as opposed to other people putting adolescents at risk. A total of 264 Australian psychologists were surveyed online. They were each presented with 68 variations of a vignette about a 15‐year‐old boy who was engaged in risk behaviour and were asked whether they would breach confidentiality in each case. The vignettes covered six behavioural domains (smoking, sexual behaviour, drinking, drug use, suicide, stealing) and varied in behaviour intensity, frequency and duration. Consensus was reached about breaching confidentiality in 16% of cases (related to sexual behaviour, drug use, and suicide). Consensus was reached about not breaching confidentiality in 41% of cases (relating to smoking, sexual behaviour, drug use, suicide, and stealing). In the remaining 43% of cases, significant disagreement occurred (relating to all six behavioural domains). The findings suggest a high degree of variation in opinion about confidentiality with adolescents, emphasising the importance of transparent communication and informed consent. The findings also raise questions about how important consistency of psychological practice is across Australia.     

Ethical Dilemmas of Confidentiality With Adolescent Clients: Case Studies From Psychologists

Navigating limits to confidentiality with adolescent clients can be ethically and professionally challenging. This study follows on from a previous quantitative survey of psychologists about confidentiality dilemmas with adolescents. The current study used qualitative methods to explore such dilemmas in greater depth. Twenty Australian psychologists were interviewed and asked to describe an ethically challenging past case. Cases were then used to facilitate discussion about the decision-making process and outcomes. Interviews were transcribed and analyzed using interpretive content and thematic analysis. Three key findings are discussed. First, it is of little use to perceive confidentiality dilemmas as binary choices (breach/don’t breach) because psychologists described 5 distinct options. These can be conceptualized on a spectrum of varying degrees of client autonomy, ranging from “no disclosure” (highest client autonomy) to “disclosure without the client’s knowledge or consent” (lowest client autonomy). Second, confidentiality dilemmas often involve balancing multiple and conflicting risks regarding both immediate and future harm. Third, a range of strategies are employed by psychologists to minimize potential harms when disclosing information. These are primarily aimed at maintaining the therapeutic relationship and empowering clients. These findings and the case studies described provide a valuable resource for teaching and professional development.     

Is Folk Psychology Different?

In this paper, I seek to refute arguments for the idea that folk psychological explanation, i.e., the explanation of actions, beliefs and desires in terms of one another, should be understood as being of a different character than ordinary scientific explanations, a view defended most prominently in analytical philosophy by Donald Davidson and John McDowell. My strategy involves arguing both against the extant arguments for the idea that FP must be construed as giving such explanations, and also against the very notion of such a different kind of explanation. I argue first that the in some sense a priori and conceptual nature of folk psychological principles does not support the idea that these are other than empirical generalisations, by appeal to recent nativist ideas in cognitive science and to Lewis's conception of the meaning of theoretical terms. Second, I argue that there is no coherent sense in which folk psychological explanations can be seen as normative. Thirdly, I examine the putatively holistic character of the mental and conclude that that too fails to provide any cogent reasons for viewing folk psychological explanations as different from other kinds of explanation.     

Anticipation skill in a real-world task: measurement,training, and transfer in tennis

Anticipation skill in tennis was examined using realistic film simulations, movement-based response measures, and a portable eye movement recording system. Skilled players were faster than their less skilled counterparts in anticipating the direction of opponents' tennis strokes, with this superior performance being based, at least in part, on more effective visual search behaviors. The processes mediating superior performance were then modeled in groups of recreational tennis players using video simulation, instruction, and feedback. Players who received perceptual training improved their performance on laboratory- and field-based tests of anticipation when compared with matched placebo and control groups that did not receive any instruction regarding expert performance strategies. The approach used may have practical utility in a variety of performance contexts.     

Culture, education, and the attribution of physical causality

Two studies investigated the impact of culturally instilled folk theories on the perception of physical events. In Study 1, Americans and Chinese with no formal physics education were found to emphasize different causes in their explanations for eight physical events, with Americans attributing them more to dispositional factors (e.g., weight) and less to contextual factors (e.g., a medium) than did Chinese. In Study 2, Chinese Americans' identity as Asians or as Americans was primed before having them explain the events used in Study 1. Asian-primed participants endorsed dispositional explanations to a lesser degree and contextual explanations to a greater degree than did American-primed participants, although priming effects were observed only for students with little physics education. Together, these studies suggest that culturally instilled folk theories of physics produce cultural differences in the perception of physical causality.     

Present but invisible: Physical obscurity fosters social disconnection

Research suggests that we feel invisible and disconnected when others avoid our gaze. In three studies, we examine whether similar feelings may arise when others are unable to meet our gaze—when they are unaware of our presence altogether. We posit that feelings of loneliness and disconnection can arise when others are unable to sense one's physical presence. To test whether invisibility engenders loneliness, we primed participants with the invisibility construct (Studies 1 and 2) and manipulated actual visibility (Study 3) prior to assessing feelings of loneliness and isolation. Results revealed that being present, but unseen, is sufficient to induce loneliness. Findings are related to the ostracism and intersectional invisibility literatures, and the social costs of physical obscurity are discussed.     

Rortian Realism

This paper motivates and defends “Rortian realism,” a position that is Rortian in respect of its underlying philosophical theses but non‐Rortian in terms of the lessons it draws from these for cultural politics. The philosophical theses amount to what the paper calls Rorty's “anti‐representationalism” (AR), arguing that AR is robust to critique as being anti‐realist, relativist, or sceptical, invoking Rorty's historicism/ethnocentrism as part of the defence. The latter, however, creates problems for Rorty in so far as his reformative views on the nature of philosophical and academic activity are meant to be foisted on an academy that ex hypothesi holds views different from these. The paper suggests we can motivate a different conception of the consequences of AR more amenable to the academy: Rortian realism, a view that makes greater concessions to realism and a kind of scientific naturalism than Rorty would like, but that for those very reasons is more likely to allow AR to prevail.     

Hoarding in obsessive-compulsive disorder: results from the OCD Collaborative Genetics Study

Hoarding behavior occurs frequently in obsessive-compulsive disorder (OCD). Results from previous studies suggest that individuals with OCD who have hoarding symptoms are clinically different than non-hoarders and may represent a distinct clinical group. In the present study, we compared 235 hoarding to 389 non-hoarding participants, all of whom had OCD, collected in the course of the OCD Collaborative Genetics Study. We found that, compared to non-hoarding individuals, hoarders were more likely to have symmetry obsessions and repeating, counting, and ordering compulsions; poorer insight; more severe illness; difficulty initiating or completing tasks; and indecision. Hoarders had a greater prevalence of social phobia and generalized anxiety disorder. Hoarders also had a greater prevalence of obsessive-compulsive and dependent personality disorders. Five personality traits were independently associated with hoarding: miserliness, preoccupation with details, difficulty making decisions, odd behavior or appearance, and magical thinking. Hoarding and indecision were more prevalent in the relatives of hoarding than of non-hoarding probands. Hoarding in relatives was associated with indecision in probands, independently of proband hoarding status. The findings suggest that hoarding behavior may help differentiate a distinct clinical subgroup of people with OCD and may aggregate in some OCD families. Indecision may be a risk factor for hoarding in these families.
