Wholes, holes, and basic features in vision

A key issue for theories of perception is specifying the primitives used by the visual system to isolate and identify the objects in an image. Although local features are typically suggested, there is good reason to look for global, configural features as primitives too. Chen et al.'s specific proposal of topological features is both explicit and capable of capturing important global information. It may seem surprising that topology can be detected by honeybees, but Chen's results are in keeping with other findings from humans that global properties are sometimes perceived better than local ones and thus might be basic.     

Ethics in Academia: Students' Vies of Professors' Actions

Although psychologist impairment has received attention from researchers, there is a paucity of empirical data aimed at determining the point at which such impairment necessitates action. The purpose of this study was to provide such empirical data. Members of Division 42 (n = 285) responded to vignettes describing a psychologist whose symptoms of either depression or substance abuse varied across five levels of severity. Results identified specific levels of impairment at which psychologists were deemed too impaired to practice psychotherapy, as well as significant differences between ratings of increasingly severe impairment. Practical and ethical implications of these results are discussed.     

Should psychotherapists disclose their own psychological problems?

Background: Self‐disclosures by psychotherapists can encompass a wide array of content, including information about the personal life of the psychotherapist. Aim: The goal of this study was to empirically assess reactions to psychotherapists disclosing their own personal problems to clients with similar problems. Methodology: This study explored participants' (n = 155) reactions to vignettes describing psychotherapists as either disclosing or not disclosing their own history of psychological problems to clients presenting with similar problems. Findings: Compared to otherwise identical vignettes featuring psychotherapists who did not self‐disclose, vignettes featuring psychotherapists who self‐disclosed were rated more positively in a variety of ways. Specifically, psychotherapists in the vignettes featuring self‐disclosure were perceived as possessing a higher level of favourable personal qualities and as more likely to establish strong working relationships with clients and achieve success in therapy. Limitations of the method and alternate explanations for the results are considered. Implications: Implications regarding the judicious use by psychotherapists of self‐disclosure regarding their own past psychological problems are discussed.     

Stereotypic head twirls, but not pacing, are related to a ‘pessimistic’-like judgment bias among captive tufted capuchins (Cebus apella)

Abnormal stereotypic behaviour is widespread among captive non-human primates and is generally associated with jeopardized well-being. However, attributing the same significance to all of these repetitive, unvarying and apparently functionless behaviours may be misleading, as some behaviours may be better indicators of stress than others. Previous studies have demonstrated that the affective state of the individual can be inferred from its bias in appraising neutral stimuli in its environment. Therefore, in the present study, in order to assess the emotional state of stereotyping individuals, 16 captive tufted capuchins (Cebus apella) were tested on a judgment bias paradigm and their faecal corticoid levels were measured in order to assess the intensity of the emotional state. Capuchins with higher levels of stereotypic head twirls exhibited a negative bias while judging ambiguous stimuli and had higher levels of faecal corticoids compared to subjects with lower levels of head twirls. Levels of stereotypic pacing, however, were not correlated with the monkeys' emotional state. This study is the first to reveal a positive correlation between levels of stereotypic behaviour and a 'pessimistic'-like judgment bias in a non-human primate by employing a recently developed cognitive approach. Combining cognitive tests that evaluate the animals' affective valence (positive or negative) with hormonal measurements that provide information on the strength of the emotional state conduces to a better understanding of the animals' affective state and therefore to their well-being.     

Mental Disorders,Comorbidity, and Pre‐enlistment Suicidal Behavior Among New Soldiers in the U.S. Army: Results from the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS)

We examined the associations between mental disorders and suicidal behavior (ideation, plans, and attempts) among new soldiers using data from the New Soldier Study (NSS) component of the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS; N = 38,507). Most new soldiers with a pre‐enlistment history of suicide attempt reported a prior mental disorder (59.0%). Each disorder examined was associated with increased odds of suicidal behavior (ORs = 2.6–8.6). Only PTSD and disorders characterized by irritability and impulsive/aggressive behavior (i.e., bipolar disorder, conduct disorder, oppositional defiant disorder, and attention‐deficit/hyperactivity disorder) predicted unplanned attempts among ideators. Mental disorders are important predictors of pre‐enlistment suicidal behavior among new soldiers and should figure prominently in suicide screening and prevention efforts.
