The magic cup: great apes and domestic dogs (Canis familiaris) individuate objects according to their properties

Despite current interest in dog (Canis familiaris) cognition, very little is known about how dogs represent objects and how they compare with other species, such as the great apes. Therefore, we investigated how dogs and great apes (chimpanzees [Pan troglodytes], bonobos [Pan paniscus], orangutans [Pongo pygmaeus], gorillas [Gorilla gorilla]) individuate objects in a classical violation of expectation paradigm. We used a container (magic cup) with a double bottom that allowed us to change the type of food that subjects had seen being placed in the container. Using a 2 × 2 design, we varied whether subjects received a generally preferred food and whether the food was substituted (surprise trials) or not (baseline trials). Apes showed increased begging and looking behaviors and dogs showed increased smelling behavior. Both species stayed near the experimenter more frequently in the surprise trials compared with baseline trials. Both species reacted to positive (i.e., good food substituted for bad food) and negative (i.e., bad food substituted for good food) surprises. These results suggest that apes and dogs were able to individuate objects according to their properties or type in comparable ways. In addition, we looked for frustration and elation effects, but subjects' behaviors were not influenced by the food they saw and which they received in previous trials.     

Assessing Emotion Regulation in Social Anxiety Disorder: The Emotion Regulation Interview

Social anxiety disorder (SAD) is thought to involve emotional hyper-reactivity and emotion dysregulation. However, the precise nature of the emotion dysregulation in SAD has not been well characterized. In the present study, the Emotion Regulation Interview (ERI) was developed to quantify the frequency and self-efficacy of five emotion regulation strategies specified by Gross’s (Review of General Psychology 2: 271–299, 1998) process model of emotion regulation. Forty-eight individuals with SAD and 33 healthy controls (HCs) were interviewed about responses during (a) a laboratory speech task and (b) two recent social anxiety-evoking situations. Individuals with SAD reported greater use of avoidance and expressive suppression than HCs, as well as lesser self-efficacy in implementing cognitive reappraisal and expressive suppression. These regulation deficits were not accounted for by differences in emotional reactivity. These findings highlight specific emotion regulation deficits in SAD, and support the idea that the Emotion Regulation Interview may be usefully applied to other clinical disorders.     

Different social motives in the gestural communication of chimpanzees and human children

Both chimpanzees and human infants use the pointing gesture with human adults, but it is not clear if they are doing so for the same social motives. In two studies, we presented chimpanzees and human 25-month-olds with the opportunity to point for a hidden tool (in the presence of a non-functional distractor). In one condition it was clear that the tool would be used to retrieve a reward for the pointing subject (so the pointing was selfish or 'for-me'), whereas in the other condition it was clear that the tool would be used to retrieve the reward for the experimenter (so the pointing was helpful or 'for-you'). The chimpanzees pointed reliably only when they themselves benefited, whereas the human children pointed reliably no matter who benefited. These results are interpreted as evidence for the especially cooperative nature of human communication.     

Masked emotional priming beyond global valence activations

An immense body of research demonstrates that emotional facial expressions can be processed unconsciously. However, it has been assumed that such processing takes place solely on a global valence-based level, allowing individuals to disentangle positive from negative emotions but not the specific emotion. In three studies, we investigated the specificity of emotion processing under conditions of limited awareness using a modified variant of an affective priming task. Faces with happy, angry, sad, fearful, and neutral expressions were presented as masked primes for 33 ms (Study 1) or 14 ms (Studies 2 and 3) followed by emotional target faces (Studies 1 and 2) or emotional adjectives (Study 3). Participants' task was to categorise the target emotion. In all three studies, discrimination of targets was significantly affected by the emotional primes beyond a simple positive versus negative distinction. Results indicate that specific aspects of emotions might be automatically disentangled in addition to valence, even under conditions of subjective unawareness.     

The Limits of Secularization? The Resurgence of Orthodoxy in Post‐Soviet Russia

The collapse of the Soviet Union ended a long period of state repression of religion, facilitating a possible religious revival in Russia. Despite evidence of increasing levels of Russian Orthodox identification in the 1990s, however, the debate over whether post‐Soviet Russia is an exception to secularization trends elsewhere continues. We address this debate by examining trends in Orthodox identification and church attendance and their impact on conservative moral values, as well as the basis of religiosity in age cohorts, using a seven‐wave national, stratified random sample survey covering 1993–2007. The analysis indicates continued growth in Orthodox self‐identification, increased church attendance, and an increasingly strong association between religiosity and conservative morality over this time period. Moreover, signs of religious revival are most pronounced among the cohort of people who came to maturity after communism ended. The resurgence of Orthodoxy in Russia provides a robust exception to secularization trends in Western Europe.     

How dogs know when communication is intended for them

Domestic dogs comprehend human gestural communication in a way that other animal species do not. But little is known about the specific cues they use to determine when human communication is intended for them. In a series of four studies, we confronted both adult dogs and young dog puppies with object choice tasks in which a human indicated one of two opaque cups by either pointing to it or gazing at it. We varied whether the communicator made eye contact with the dog in association with the gesture (or whether her back was turned or her eyes were directed at another recipient) and whether the communicator called the dog's name (or the name of another recipient). Results demonstrated the importance of eye contact in human-dog communication, and, to a lesser extent, the calling of the dog's name--with no difference between adult dogs and young puppies--which are precisely the communicative cues used by human infants for identifying communicative intent. Unlike human children, however, dogs did not seem to comprehend the human's communicative gesture when it was directed to another human, perhaps because dogs view all human communicative acts as directives for the recipient.     

Examining the Impact of Dons Providing Peer Instruction for Academic Integrity: Dons’ and Students’ Perspectives

A peer instruction model was used whereby 78 residence dons (36 males, 42 females) provided instruction regarding academic integrity for 324 students (125 males, 196 females) under their supervision. Quantitative and qualitative analyses were conducted to assess survey responses from both the dons and students regarding presentation content, quality, and learning. Overall, dons consistently identified information-based slides about academic integrity as the most important material for the presentations, indicating that fundamental information was needed. Although student ratings of the usefulness of the presentations were middling, students did indicate knowledge gains. Both interest and personal value for academic integrity were highly predictive of positive evaluations of the presentations. Dons and students provided suggestions for improvement and identified more global concerns.     

Exploring Socioeconomic Differences in Bedtime Behaviours and Sleep Duration in English Preschool Children

Children's sleep is critical for optimal health and development; yet sleep duration has decreased in recent decades, and many children do not have adequate sleep. Certain sleep behaviours (‘sleep hygiene’) are commonly recommended, and there is some evidence that they are associated with longer nighttime sleep. Parents of 84 British 3‐year‐old children were interviewed about their children's sleep and completed five‐night/four‐day sleep diaries documenting their children's sleep, from which daily sleep duration was estimated. Diaries were validated by actigraphy in a subgroup of children. Sleep hygiene behaviours (regular bedtime, reading at bedtime, falling asleep in bed) were associated with each other, and were more common in the high socioeconomic status compared to the low socioeconomic status group. Parents' reasons for not practicing sleep hygiene included difficulty, inability or inconvenience. Sleep hygiene behaviours were associated with significantly longer child sleep at night but not over 24 h. Longer daytime napping compensated for shorter nighttime sleep in children whose parents did not implement sleep hygiene behaviours. Parents may need to be advised that certain behaviours are associated with longer nighttime sleep and given practical advice on how to implement these behaviours. © 2014 The Authors.

Enculturation and Attitudes Toward Intimate Partner Violence and Gender Roles in an Asian Indian Population: Implications for Community-Based Prevention

This study examined the relationships among enculturation, attitudes supporting intimate partner violence (IPV-supporting attitudes), and gender role attitudes among one of the largest Asian Indian population groups in the US. Data were collected via computer-assisted telephone interviews with a random sample of Gujarati men and women aged 18–64 in Metropolitan Detroit. Using structural equation modeling, we modeled the effects of three components of enculturation (behavior, values, and community participation) on gender role attitudes and IPV-supporting attitudes among married respondents (N = 373). Analyses also accounted for the effects of respondent age, education, religious service attendance, perceived financial difficulty, and lengths of residence in the US. The second-order, overall construct of enculturation was the strongest predictor of IPV-supporting attitudes (standardized B = 0.61), but not gender role attitudes. Patriarchal gender role attitudes were positively associated with IPV-supporting attitudes (B = 0.49). In addition to the overall effect of the enculturation construct, two of the components of enculturation had specific effects. “Enculturation-values” had a specific positive indirect association with IPV-supporting attitudes, through its relationship with patriarchal gender role attitudes. However, “enculturation-community participation” was negatively associated with IPV-supporting attitudes, suggesting the importance of community-based prevention of IPV among this immigrant population group.     

Burnout and the Fine‐Tuning of Cognitive Resources

We examined the performance in a constant foreperiod task in two samples screened for either high or low scores on the core burnout dimension emotional exhaustion. In line with our expectations, participants scoring high on emotional exhaustion exhibited a specific deficit with respect to maintaining a high level of response readiness at longer foreperiods. This demonstration of a modulation of constant foreperiod performance by burnout adds to the growing body of evidence suggesting that exhaustion is related to deficits in basic cognitive mechanisms underlying the fine‐tuning of cognitive resources according to task demands.
