Childhood Cruelty to Animals: Psychiatric and Demographic Correlates

This retrospective study compared frequencies of aggressive behaviors and abuse histories noted during a psychiatric intake assessment for children where animal cruelty was endorsed and a control sample of youth for whom animal cruelty was not endorsed to determine if rates of concerning behaviors differed significantly. Relative to the control group, the cruelty group was significantly more likely to have had problems with peers, perpetrated bullying, experienced sexual abuse, and have a history of sexually acting out. Recommendations for childhood animal cruelty screening in mental health settings are discussed.     

A Psychogenic Study of Dark-Adaptation

Skin conductance responses (SCRs), heart rate (HR), and respiration were recorded in various rest, cold pressor (CP), and CP recovery phases in 20 former drug users (DG) and 20 control Ss (CG), matched on sex and age in a repeated measures design. With regard to the abused drugs (barbiturates and narcotic analgesics), the hypothesis was tested that autonomic responses are decreased after long-term use of barbiturates and narcotic analgesics. The results partially supported that hypothesis: (a) SCRs, HR change, and HR deceleration were significantly lower in DG compared to control Ss; (b) HR baseline, respiration rate, and amplitude, however, tended to be increased in DG in the rest and CP phases. A second hypothesis, addressed to different habituation rates of SCRs and HR in both groups, was confirmed for SCRs and partly for HR, indicating that the habituation rates of SCRs, HR change, and HR deceleration were greater in DG than in CG. A third question concerned the consistency of SCR and HR results in both sessions. A trend for consistent results was found as the direction of the group differences was the same in sessions 1 and 2. The CP results were compared with similar findings in the same Ss during visual and auditory stimulation.     

THE IMAGO DEI AS THE MIND OF JESUS CHRIST

In this essay I examine David Clough's interpretation of the imago Dei and his use of “creaturely” language in his book On Animals: Volume 1, Systematic Theology. Contrary to Clough, I argue that the imago Dei should be interpreted as being uniquely human. Using a neuroscientific approach, I elaborate on my claim that while Jesus is the image of God perfected, the imago Dei is best understood as having the mind of Christ. In regards to language, I make the case that using terms such as “creature” when referring to nonhuman animals is problematic in that it can serve to alienate human beings from their capacity to image God. In addition I argue that “creaturely” language raises concerns for the African American community given Western Christianity's history as it relates to their valuation of black bodies and human enslavement.     

Evaluating a humane alternative to the bark collar: Automated differential reinforcement of not barking in a home‐alone setting

The aim of this study was to develop a humane alternative to the traditional remote devices that deliver punishers contingent on home‐alone dog barking. Specifically, we evaluated the use of remote delivery of food contingent on intervals of not barking during the pet owner's absence. In Experiment 1, 5 dogs with a history of home‐alone nuisance barking were recruited. Using an ABAB reversal design, we demonstrated that contingent remote delivery of food decreased home‐alone barking for 3 of the dogs. In Experiment 2, we demonstrated that it is possible to thin the differential‐reinforcement‐of‐other‐behavior (DRO) schedule gradually, resulting in a potentially more acceptable treatment. Our results benefit the dog training community by providing a humane tool to combat nuisance barking.     

An attachment perspective on human-pet relationships: Conceptualization and assessment of pet attachment orientations

In a series of studies we used attachment theory as a framework to examine human-pet relationships. We proposed that, as in interpersonal relationships, people differ in their degree of anxious or avoidant attachment to their pets, and that these individual differences influence pet-related cognitions, emotions, and behavior. We constructed a self-report scale, the Pet Attachment Questionnaire (PAQ), and examined its factorial structure, associations with attachment patterns in human relationships (Studies 1-2), relation to explicit and implicit expectations concerning a pet (3-4), and reactions to the loss of a pet (5). We found that individual differences in pet attachment do occur in the domains of attachment anxiety and avoidance, and these differences contribute uniquely to the prediction of expectations about the pet and emotional reactions to its death.     

Using trained pouched rats to detect land mines: another victory for operant conditioning

We used giant African pouched rats (Cricetomys gambianus) as land mine-detection animals in Mozambique because they have an excellent sense of smell, weigh too little to activate mines, and are native to sub-Saharan Africa, and therefore are resistant to local parasites and diseases. In 2009 the rats searched 93,400 m(2) of land, finding 41 mines and 54 other explosive devices. Humans with metal detectors found no additional mines. On average, the rats emitted 0.33 false alarm for every 100 m(2) searched, which is below the threshold given by International Mine Action Standards for accrediting mine-detection animals. These findings indicate that Cricetomys are accurate mine-detection animals and merit continued use in this capacity.     

Developmental changes in colour constancy in a naturalistic object selection task

When the illumination falling on a surface change, so does the reflected light. Despite this, adult observers are good at perceiving surfaces as relatively unchanging—an ability termed colour constancy. Very few studies have investigated colour constancy in infants, and even fewer in children. Here we asked whether there is a difference in colour constancy between children and adults; what the developmental trajectory is between six and 11 years; and whether the pattern of constancy across illuminations and reflectances differs between adults and children. To this end, we developed a novel, child-friendly computer-based object selection task. In this, observers saw a dragon's favourite sweet under a neutral illumination and picked the matching sweet from an array of eight seen under a different illumination (blue, yellow, red, or green). This set contained a reflectance match (colour constant; perfect performance) and a tristimulus match (colour inconstant). We ran two experiments, with two-dimensional scenes in one and three-dimensional renderings in the other. Twenty-six adults and 33 children took part in the first experiment; 26 adults and 40 children took part in the second. Children performed better than adults on this task, and their performance decreased with age in both experiments. We found differences across illuminations and sweets, but a similar pattern across both age groups. This unexpected finding might reflect a real decrease in colour constancy from childhood to adulthood, explained by developmental changes in the perceptual and cognitive mechanisms underpinning colour constancy, or differences in task strategies between children and adults.

Highlights

• Six- to 11-year-old children demonstrated better performance than adults on a colour constancy object selection task.
• Performance decreased with age over childhood.
• These findings may indicate development of cognitive strategies used to overcome automatic colour constancy mechanisms.
