REVIEW
Thomas N Sherratt, Casey A Peet-Paré
We consider why imperfect deceptive mimics can persist when it appears to be in the predator's interest to discriminate finely between mimics and their models. One theory is that a receiver will accept being duped if the model and mimic overlap in appearance and the relative costs of attacking the model are high. However, a more fundamental explanation for the difficulty of discrimination is not based on perceptual uncertainty, but simply based on a lack of information. In particular, predators in the process of learning may cease sampling imperfect mimics entirely because the immediate pay-off and future value of information is low, allowing such mimics to persist...

This research presented 8-, 10-, and 12-year-olds (N = 120) with hypothetical situations depicting comparably aged children engaging in defiance and deception to circumvent authorities' directives that they disagreed with. The nature of the situations varied in terms of domain (personal, moral, or prudential) and type of authority figure (parent or teacher). Evaluations and justifications for the legitimacy of the directives, defiance, and deception were examined, as were general evaluations of deception. Across domains, increased age was associated with decreased acceptance of directives, and increased acceptance of defiance and deception...

OBJECTIVES: The diagnosis of peripheral tubercular lymphadenopathy (TBLN) in pediatric patients is often a challenge because features evident on fine-needle aspiration cytology (FNAC) or tissue biopsy can be deceptive for the reason that they result from an immunological response. This study aimed to evaluate polymerase chain reaction (PCR) for Mycobacterium tuberculosis complex (MTBC) in pediatric patients under clinical suspicion for TBLN and to assess its role in the evaluation of cases cytodiagnosed as reactive lymphoid hyperplasia...

BACKGROUND: Polyandry is commonly maintained by direct benefits in gift-giving species, so females may remate as an adaptive foraging strategy. However, the assumption of a direct benefit fades in mating systems where male gift-giving behaviour has evolved from offering nutritive to worthless (non-nutritive) items. In the spider Paratrechalea ornata, 70% of gifts in nature are worthless. We therefore predicted female receptivity to be independent of hunger in this species. We exposed poorly-fed and well-fed females to multiple males offering nutritive gifts and well-fed females to males offering worthless gifts...

BACKGROUND: Detection of dorsal cortical penetration of distal locking screws is difficult owing to the irregular shape of the dorsal surface of the distal radius. This study was designed to analyze two-dimensional morphological characteristics of the distal radius on axial magnetic resonance image, and to suggest a guideline for evaluation of screw length in distal radius fractures on the fluoroscopic or plain X-ray true lateral image. METHODS: Anteroposterior length and lateral width of the distal radius, distance between the highest and the lowest point of the dorsal cortex (deceptive length), and widths of the first to second (hazard zone) and the third to fifth extensor compartments (safe zone) at the Lister tubercle level were measured on 104 axial magnetic resonance images by two hand surgeons...

Acute myocarditis mimicking ST-segment elevation myocardial infarction (STEMI) is highly deceptive for an accurate diagnosis, and a systematic study is lacking with regard to the clinical features and prognosis of this distinct clinical entity.Patients with suspected STEMI and eventually diagnosed with myocarditis by cardiac magnetic resonance (CMR) from January 2012 to April 2016 at Fuwai Hospital were identified by reviewing medical records and electronic databases. Follow-up was conducted by clinical visits and phone contacts in a median duration of 17 months...

Background: The study aimed to determine whether a patient's choice for their intrathecal morphine (ITM) dose reflects their opioid requirements and pain after caesarean delivery and if giving women a choice of ITM dose would reduce opioid use and improve pain scores compared with women who did not have a choice. Methods: A total of 120 women undergoing caesarean delivery with spinal anaesthesia were enrolled in this randomized, double-blind study. Patients were randomly assigned to a choice of 100 or 200 μg ITM or no choice...

REVIEW
Saul M Kassin
As illustrated by numerous cases in recent years, DNA exonerations of innocent individuals have cast a spotlight on the counterintuitive problem of false confessions. Studying the underlying psychology scientists have found that (1) innocent people are often targeted for interrogation because police make erroneous but confident judgments of deception; (2) certain interrogation techniques-namely, lengthy sessions, presentations of false evidence, and minimization themes that imply leniency-increase the risk that innocent people will confess; (3) certain individuals are particularly vulnerable to influence-notably, those with mental health problems or intellectual impairments, which render them overly compliant or suggestible, and children and adolescents, who exhibit 'immaturity of judgment'; (4) confession evidence is highly persuasive in court as a matter of common sense, increasing perceptions of guilt, even among judges and juries who see the confession as coerced, and even at times when the confession is contradicted by exculpatory information; (5) Miranda rights to silence and to counsel are not sufficiently protective, so proposals for reform have centered on the mandatory recording of interrogations, from start to finish, and a shift toward using investigative interviewing-a less confrontational, less deceptive means of questioning suspects...

In this commentary, we consider questions related to research integrity in data-intensive science and argue that there is no need to create a distinct category of misconduct that applies to deception related to processing, analyzing, or interpreting data. The best way to promote integrity in data-intensive science is to maintain a firm commitment to epistemological and ethical values, such as honesty, openness, transparency, and objectivity, which apply to all types of research, and to promote education, policy development, and scholarly debate concerning appropriate uses of statistics...

Oral pulse granuloma (PG) is a rare lesion that presents as a foreign body granulomatous reaction to implanted food particles of plant or vegetable origin. It is classified as a central or a peripheral lesion depending on the location. Rarely, a central oral PG may be associated with a cyst or tumor, thus leading to a deceptive histopathological picture. This is exemplified in the present case of 27-year-old female patient who reported with a swelling on the left posterior region of mandible which was diagnosed as ameloblastoma...

One of the most intriguing natural observations is the pollination of orchids by sexual deception. Here, we identify floral semiochemicals from Caladenia (spider orchids) for the first time. We demonstrate that C. crebra, attracts its single pollinator species with a unique system of (methylthio)phenols, three of which are new natural products. Furthermore, the same compounds constitute the sex pheromone of the pollinator, the thynnine wasp Campylothynnus flavopictus, representing the first occurrence of sulfurous sex pheromones in Hymenoptera...

Decision-making is rarely context-free, and often both social information and non-social information are weighed into one's decisions. Incorporating information into a decision can be influenced by previous experiences. Ostracism has extensive effects, including taxing cognitive resources and increasing social monitoring. In decision-making situations, individuals are often faced with both objective and social information and must choose which information to include or filter out. How will ostracism affect the reliance on objective and social information during decision-making? Participants (N=245) in Experiment 1 were randomly assigned to be included or ostracized in a standardized, group task...

BACKGROUND: Aphids, including the generalist herbivore Myzus persicae, transmit cucumber mosaic virus (CMV). CMV (strain Fny) infection affects M. persicae feeding behavior and performance on tobacco (Nicotiana tabacum), Arabidopsis thaliana and cucurbits in varying ways. In Arabidopsis and cucurbits, CMV decreases host quality and inhibits prolonged feeding by aphids, which may enhance virus transmission rates. CMV-infected cucurbits also emit deceptive, aphid-attracting volatiles, which may favor virus acquisition...

We describe a patient with missed traumatic pneumothorax due to penetrating neck injury that was presumably caused by a stingray while diving. The barb can result in significant injuries to deep structures and organs despite a deceptively small entrance wound. This case underscores the importance of performing a thorough examination and having a high suspicion of distant injury in patients with penetrating neck injuries.

Patients with factitious disorders intentionally fabricate, exaggerate or feign physical and/or psychiatric symptoms for various open and covert psychological reasons. There are many issues regarding the diagnostic state and classification of factitious disorders. Both the categorical differentiation of and clinical continuum ranging from somatoform/dissociative disorders to malingering are being controversially debated. Epidemiological studies on the frequency of factitious disorder meet basic methodological difficulties...

INTRODUCTION: Risk of developing type 2 diabetes is increased in women with previous gestational diabetes mellitus (GDM). Postpartum glycemic screening is recommended in women with recent GDM. But this screening rate is low and the reasons are unclear. The aim of this study was to explore the experiences of Iranian women with recent GDM on barriers of postpartum screening for diabetes. METHODS: This qualitative study was conducted in Tehran, Iran in 2016. Semi-structured interview was used for data collection...

BACKGROUND: Deception detection has been a longstanding concern throughout human history. It has also interested scientists, who have explored psychological and behavioral differences between liars and truth tellers, as well as ways to improve detection accuracy. METHOD: In recent years, substantial advances have been made in the field. Some of these advances are briefly reviewed in the current article. RESULTS: A description is provided of (a) research and contemporary theories on how people (try to) detect deception; (b) recent advances on strategic interviewing to detect deception; (c) the integrative findings of recent meta-analyses on systematic verbal lie detection approaches; and (d) several important aspects concerning psychophysiological detection of deception...

When it comes to lies, the beneficiaries of one's dishonesty play an important role in the decision-making process. Altruistic lies that are made with the intention of benefiting others are a specific type of lies and very common in real life. While it has been shown that altruistic goals influence (dis)honest behaviors, the neural substrates of this effect is still unknown. To reveal how the brain integrates altruistic goals into (dis)honest decisions, this study used functional magnetic resonance imaging to examine the neural activity of participants in a real incentivized context while they were making (dis)honest decisions...

A specific psychotherapeutic strategy for increasing psychological well-being and resilience, well-being therapy (WBT), has been developed and validated in a number of randomized controlled trials. The findings indicate that flourishing and resilience can be promoted by specific interventions leading to a positive evaluation of one's self, a sense of continued growth and development, the belief that life is purposeful and meaningful, the possession of quality relations with others, the capacity to manage effectively one's life, and a sense of self-determination...
