Estimation of consumer willingness‐to‐pay for social responsibility in fruit and vegetable products: A cross‐country comparison using a choice experiment

Choice experiments are used to assess consumer preferences and willingness‐to‐pay (WTP) for different food attributes worldwide. These studies also include credence attributes which are the product attributes that are not immediately observable to consumers without appropriate information and labelling, such as animal welfare, food safety, and social responsibility. Although choice experiment application has considered many of these attributes, studies focused on social responsibility are scant. Building on previous work comparing developed and developing countries, this paper focuses on WTP estimation for social responsibility. Surveys of fruit and vegetable consumers were conducted in United Kingdom (UK), Japan, India, and Indonesia in 2015. Results indicate WTP for an increase from minimum to improved standard for social responsibility ranges from 16% to 30% (median), and 6% to 26% (median) from improved to a high standard. Premiums vary between countries but, overall, demonstrate the significant importance of social responsibility consideration in consumer choices. Significant differences on WTP were observed between Japan and other countries, as well as between UK and Indonesia for the improved social responsibility standard, and across UK, Indonesia, and India for the high standard. Findings contribute to increasing understanding of consumer preferences across countries, revealing significant preference heterogeneity towards social responsibility.     

Recognition of novel faces after single exposure is enhanced during pregnancy

Protective mechanisms in pregnancy include Nausea and Vomiting in Pregnancy (NVP) (Fessler, 2002; Flaxman and Sherman, 2000), increased sensitivity to health cues (Jones et al., 2005), and increased vigilance to out-group members (Navarette, Fessler, and Eng, 2007). While common perception suggests that pregnancy results in decreased cognitive function, an adaptationist perspective might predict that some aspects of cognition would be enhanced during pregnancy if they help to protect the reproductive investment. We propose that a reallocation of cognitive resources from nonessential to critical areas engenders the cognitive decline observed in some studies. Here, we used a recognition task disguised as a health rating to determine whether pregnancy facilitates face recognition. We found that pregnant women were significantly better at recognizing faces and that this effect was particularly pronounced for own-race male faces. In human evolutionary history, and today, males present a significant threat to females. Thus, enhanced recognition of faces, and especially male faces, during pregnancy may serve a protective function.

The Neuropsychology of Heading and Head Trauma in Association Football (Soccer): A Review

Association Football (soccer) is the most popular and widespread sport in the world. A significant proportion of the injuries suffered in football are head injuries involving trauma to the brain. In normal play, head trauma frequently arises from collisions, but some researchers have claimed that it also may arise as a consequence of heading the ball. Although assessments based on biomechanical analyses are equivocal on the potential for brain injury due to football heading, a growing literature seems to support the claim that neuropsychological impairment results from general football play and football heading in particular. However, this review suggests a distinction is required between the neuropsychological effects of concussive and subconcussive head trauma and that all of the neuropsychological studies conducted so far suffer from methodological problems. At best, a few of these studies may be regarded as exploratory. The review concludes that presently, although there is exploratory evidence of subclinical neuropsychological impairment as a consequence of football-related concussions, there is no reliable and certainly no definitive evidence that such impairment occurs as a result of general football play or normal football heading. The neuropsychological consequences of football-related subconcussive effects await confirmatory investigation.     

B.F. Skinner and the auditory inkblot: The rise and fall of the verbal summator as a projective technique

Behaviorist B.F. Skinner is not typically associated with the fields of personality assessment or projective testing. However, early in his career Skinner developed an instrument he named the verbal summator, which, at one point, he referred to as a device for "snaring out complexes," much like an auditory analogue of the Rorschach inkblots. Skinner's interest in the projective potential of his technique was relatively short lived, but whereas he used the verbal summator to generate experimental data for his theory of verbal behavior, several other clinicians and researchers exploited this potential and adapted the verbal summator technique for both research and applied purposes. The idea of an auditory inkblot struck many as a useful innovation, and the verbal summator spawned the tautophone test, the auditory apperception test, and the Azzageddi test, among others. This article traces the origin, development, and eventual demise of the verbal summator as an auditory projective technique.     

Individual differences in emotional expression discrimination are associated with emotion label production in toddlers

It is possible that the visual discrimination of emotion categories and emotion word vocabulary develop via common emotion-specific processes. In contrast, it is possible that they develop with vocabulary development more generally. This study contrasts these two possibilities. Twenty-three 26-month-olds participated in a visual perceptual discrimination task involving emotional facial expressions. After familiarization to a 100% happy face, toddlers were tested for their visual preference for a novel sad face in a side-by-side presentation paired with the familiar happy face. Parental report was used to quantify production of emotion words and vocabulary generally. Visual preference for the novel emotion (sad) in the discrimination task correlated with emotion word vocabulary size but not with overall vocabulary size.     

A threat-detection advantage in those with autism spectrum disorders

Identifying threatening expressions is a significant social perceptual skill. Individuals with autism spectrum disorders (ASD) are impaired in social interaction, show deficits in face and emotion processing, show amygdala abnormalities and display a disadvantage in the perception of social threat. According to the anger superiority hypothesis, angry faces capture attention faster than happy faces in individuals with a history of typical development [Hansen, C. H., & Hansen, R. D. (1988). Finding the face in the crowd: An anger superiority effect. Journal of Personality and Social Psychology, 54(6), 917–924]. We tested threat detection abilities in ASD using a facial visual search paradigm. Participants were asked to detect an angry or happy face image in an array of distracter faces. A threat-detection advantage was apparent in both groups: participants showed faster and more accurate detection of threatening over friendly faces. Participants with ASD showed similar reaction time, but decreased overall accuracy compared to controls. This provides evidence for less robust, but intact or learned implicit processing of basic emotions in ASD.     

INCREASING THE ACCURACY OF CORRECTIONS FOR RANGE RESTRICTION: IMPLICATIONS FOR SELECTION PROCEDURE VALIDITIES AND OTHER RESEARCH RESULTS

The common practice in meta-analyses and in individual studies of correcting for direct range restriction even though range restriction is actually indirect has long been known to lead to undercorrection, but this error has been assumed to be small. Using validity generalization data sets for 4 jobs, this study calibrated this error by comparing meta-analysis results based on corrections for direct range restriction with the more accurate results from a recently developed method of correcting for indirect range restriction. It was found that, on average, correction for direct range restriction resulted in substantial underestimation of operational validities for both job performance measures (21%) and training performance measures (28%). In addition, 90% credibility values were on average underestimated by 38%–40%. In addition to the implications for personnel selection, these findings suggest that similar underestimation of important relationships has occurred in other areas of research, with potential implications for theory development.     

Do we look happy? Perceptions of romantic relationship quality on Facebook

Does the information that people share about their romantic relationships on Facebook influence how other people perceive their relationship quality? Across 2 studies, people's accuracy at inferring others' relationship quality based on their Facebook profiles and how Facebook profiles influenced others' judgments of people's relationship quality and likability were investigated. Perceived relationship quality corresponded to self‐reported relationship quality (Study 1), and people with more visible relationships were perceived as having greater relationship satisfaction and commitment (Studies 1 and 2) and being more likable (Study 2). High disclosure about the relationship predicted greater perceived relationship quality but lower likability (Study 2). These findings illuminate how sharing information about one's relationship influences other people's impressions of the individual and the relationship.
