Do wild New Caledonian crows (<Emphasis Type="Italic">Corvus moneduloides</Emphasis>) attend to the functional properties of their tools?

New Caledonian crows are the most proficient non-hominin tool manufacturers but the cognition behind their remarkable skills remains largely unknown. Here we investigate if they attend to the functional properties of the tools that they routinely use in the wild. Pandanus tools have natural barbs along one edge that enable them to function as hooking implements when the barbs face backwards from the working tip. In experiment 1 we presented eight crows with either a non-functional (‘upside-down’) or a functional pandanus tool in a baited hole. Four of the crows never flipped the tools. The behaviour of the four flipping birds suggested that they had a strategy of flipping a tool when it was not working. Observations of two of the eight crows picking up pandanus tools at feeding tables in the wild supported the lack of attention to barb direction. In experiment 2 we gave six of the eight crows a choice of either a barbed or a barbless pandanus tool. Five of the crows chose tools at random, which further supported the findings in experiment 1 that the crows paid little or no attention to the barbs. In contrast, a third experiment found that seven out of eight crows flipped non-functional stick tools significantly more than functional ones. Our findings indicate that the crows do not consistently attend to the presence or orientation of barbs on pandanus tools. Successful pandanus tool use in the wild seems to rely on behavioural strategies formed through associative learning, including procedural knowledge about the sequence of operations required to make a successful pandanus tool.

Disinhibition of stereotyping: context,prejudice, and target characteristics

The present research examined the moderating influences of individual differences in sexism on the application of gender stereotypes to stereotypic versus nonstereotypic targets as a function of contexts that induced sex stereotypic or counterstereotypic responses. Specifically, participants first received an attribution task in which they were induced to explain a variety of gender relevant situations in gender stereotypic or nonstereotypic ways. Participants were then presented with an ostensibly unrelated person judgment task in which they were asked to judge two women who acted either ambiguously stereotypically or nonstereotypically. The initial opportunity to express stereotypes without censure accentuated stereotype application, but only for highly prejudiced participants rating a woman who acted in an ambiguously stereotypical (i.e. unassertive) manner. We consider the implications of these findings for processes of stereotype disinhibition, and the moderating influences of individual differences in prejudice, target characteristics, and local norms.

The Interplay of Low Identification,Psychological Detachment,and Cynicism for Predicting Counterproductive Work Behaviour

Prior research suggests that psychological detachment buffers the detrimental effects of negative work events and stressors on employees’ subsequent performance and well-being. This, however, assumes that employees are motivated to reengage in their work following detachment, which may not always be true. Our paper examines the potential dark side of psychological detachment by exploring its moderating effects on the relationship of low organisational identification with counterproductive work behaviour (CWB) via cynicism toward work. Based on self-discrepancy theory, we argue that detachment strengthens the link from low identification to cynicism because it reinforces the psychological distance of lowly identified employees with the organisation and provides them with additional resources to more deeply reflect on their mismatch with their organisation, thus generating stronger feelings of doubt and distrust that characterise cynicism. We also hypothesise that detachment strengthens the relation from cynicism to CWB, because detachment reinforces personal separation from work in cynical employees and because cynical employees may leverage their replenished resources to fuel deviant acts. Multi-wave data collected from two field samples support our hypotheses. We discuss the implications of our study and propose future research directions.     

Doing Justice to Difference: Stanley Hauerwas and Public Theology

Stanley Hauerwas’s theology is widely read as a rejection of the world in favor of the church, and thus the antithesis of politically-engaged, publicly-minded theologies like Reinhold Niebuhr's. However, Hauerwas's critical work can be more fruitfully understood as an effort in disambiguating concepts like “love” and “justice.” Attending to the role language plays in Hauerwas's thought shows how neo-Anabaptist theology acts as a corrective to, not a rejection of, public theology. Charles Mathewes's The Republic of Grace is one example of a neo-Augustinian political theology that takes Hauerwas's conceptual clarifications seriously.     

Consumer behaviour and the toilet: Research on expulsive and retentive personalities

During the last five decades, a number of studies have attempted to draw from psychoanalytic theory to examine the relationship between evacuation disorders and a person's character. According to Freud's original conceptualization, early or harsh toilet training leads children to develop an anal retentive personality, characterized by the tendency to control their bowels as well as their material possessions; by contrast, liberal toilet training leads children to develop an anal expulsive personality, characterized by the tendency to excessively relieve faeces, as well as be being careless, messy, and inclined to dispose of old products and buy new ones. Although toilet training may not be responsible, these sets of traits do cohere. To empirically examine these hypotheses, we studied the personality traits and consumption habits of people suffering from different bowel disorders. By means of semistructured interviews, we analysed the personality characteristics, sociodemographic backgrounds, and peculiar consumption habits of people suffering from constipation and diarrhoeic syndromes. The results show that constipated people tend to be obstinate, excessively concerned with hygiene, and inclined toward retaining possessions, whereas diarrhoeic people tend to be careless, disorganized, and disposed to share their possessions with others. We discuss the theoretical and practical implications of these results and indicate avenues for future research.     

Willingness to Seek Treatment Among Black Students With Anxiety or Depression: The Synergistic Effect of Sociocultural Factors With Symptom Severity and Intolerance of Uncertainty

Anxiety and depressive disorders are among the most commonly diagnosed psychiatric disorders, yet they remain largely undertreated in the U.S. and Black adults are especially unlikely to seek or receive mental health services. Symptom severity has been found to impact treatment-seeking behaviors as have sociocultural factors. Yet no known research has tested whether these factors work synergistically to effect willingness to seek treatment. Further, emerging data point to the importance of transdiagnostic risk factors such as intolerance of uncertainty (IU). IU may be negatively related to seeking treatment given that Black adults may be uncertain whether treatment might benefit them. Thus, the current study examined the relations between symptom severity/IU and willingness to seek treatment for anxiety/depression problems and the impact of key sociocultural variables (i.e., cultural mistrust–interpersonal relations [CMI-IR], perceived discrimination [PED]) on these relations among 161 (85% female) Black undergraduates. Consistent with prediction, symptom severity was positively related to willingness, but unexpectedly, IU was positively related. There was a significant Symptom Severity × CMI-IR interaction such that severity was positively related to willingness among students with lower cultural mistrust, but not higher mistrust. There were also significant IU × PED interaction such that IU was positively related to willingness among students with lower PED, but not higher PED. Results highlight the importance of considering the interplay between symptom severity, transdiagnostic vulnerability factors, and sociocultural variables when striving to identify factors related to treatment seeking behaviors among anxious and/or depressed Black students.     

Facial expressions as performances in mime

That facial expressions are universal emotion signals has been supported by observers agreeing on the emotion mimed by actors. We show that actors can mime a diverse range of states: emotions, cognitions, physical states, and actions. English, Hindi, and Malayalam speakers (N?=?1200) viewed 25 video clips and indicated the state conveyed. Within each language, at least 23 of the 25 clips were recognised above chance and base rate. Facial expressions of emotions are not special in their recognisability, and it is miming that may be the universal human ability.     

On an Observer’s Reaction to Hearing of Someone Harming Him or Herself

Anthropological studies in India inspired the idea of a distinct domain of moral purity, but a precise characterization of that domain has been elusive. One proposal based on current theorizing in psychology is that prototypical purity violations are self-harming actions, which are perceived as disgusting and immoral whether done accidentally or intentionally. In three studies (Ns?=?400, 80, 132), we examined judgments of self-harming actions in two cultural groups—American and Indian. There was little support for the proposed characterization of the purity domain: Self-harms were slightly to modestly immoral for Indians and Americans. Both Indians and Americans found self-harms to be sad, not disgusting. And intentionality influenced how immoral and how sad the action was judged. Instead, the findings supported a view that all immorality, including those concerning self-harm, depends on perceived harm.     

Intention as action under development: why intention is not a mental state

This paper constructs a theory according to which an intention is not a mental state but an action at a certain developmental stage. I model intention on organic life, and thus intention stands to action as (e.g.) tadpole stands to frog. I then argue for this theory by showing how it overcomes three problems: intending while (1) merely preparing, (2) not taking any steps, and (3) the action is impossible. The problems vanish when we see that not all actions are mature. Just as some frogs (such as tadpoles) are immature frogs, some actions (such as intentions) are immature actions.
