Creation and validation of the Picture-Set of Young Children’s Affective Facial Expressions (PSYCAFE)

The immediate detection and correct processing of affective facial expressions are one of the most important competences in social interaction and thus a main subject in emotion and affect research. Generally, studies in these research domains, use pictures of adults who display affective facial expressions as experimental stimuli. However, for studies investigating developmental psychology and attachment behaviour it is necessary to use age-matched stimuli, where it is children that display affective expressions. PSYCAFE represents a newly developed picture-set of children’s faces. It includes reference portraits of girls and boys aged 4 to 6 years averaged digitally from different individual pictures, that were categorized to six basic affects (fear, disgust, happiness, sadness, anger and surprise) plus a neutral facial expression by cluster analysis. This procedure led to deindividualized and affect prototypical portraits. Individual affect expressive portraits of adults from an already validated picture-set (KDEF) were used in a similar way to create affect prototypical images also of adults. The stimulus set has been validated on human observers and entail emotion recognition accuracy rates and scores for intensity, authenticity and likeability ratings of the specific affect displayed. Moreover, the stimuli have also been characterized by the iMotions Facial Expression Analysis Module, providing additional data on probability values representing the likelihood that the stimuli depict the expected affect. Finally, the validation data from human observers and iMotions are compared to data on facial mimicry of healthy adults in response to these portraits, measured by facial EMG (m. zygomaticus major and m. corrugator supercilii).

From the Horse’s Perspective: Investigating Attachment Behaviour and the Effect of Training Method on Fear Reactions and Ease of Handling—A Pilot Study

The study investigated equine responses to novelty and handling, aiming to reveal whether horse–human relationships reflect criteria of an attachment bond. Twelve adult Standardbreds were subjected to a fear-eliciting test (novel objects presented close to two humans) and a handling test (being led passing novel objects) to study attachment-related behaviours and ease of handling. The tests were performed both before (pre-test) and after (post-test) horses had been trained by the same female handler (10 sessions of 15 min). Horses were assigned to three groups of four, each of which underwent different operant conditioning protocols: negative reinforcement (NR; pressure, release of lead, and whip tap signals) or combined NR with either positive reinforcement using food (PRf) or wither scratching (PRs). Results showed that neither familiarity of the person nor training method had a significant impact on the horses’ behavioural responses in the post-tests. However, horses showed decreased heart rates between pre- and post-tests, which may indicate habituation, an effect of training per se, or that the presence of the familiar trainer served to calm the horses during the challenging situations. There were large individual variations among the horses’ responses and further studies are needed to increase our understanding of horse–human relationships.

Adult, intensively socialized wolves show features of attachment behaviour to their handler

Dogs’ attachment towards humans might be the core of their social skillset, yet the origins of their ability to build such a bond are still unclear. Here we show that adult, hand-reared wolves, similarly to dogs, form individualized relationship with their handler. During separation from their handler, wolves, much like family dogs, showed signs of higher-level stress and contact seeking behaviour, compared to when an unfamiliar person left them. They also used their handler as a secure base, suggesting that the ability to form interspecific social bonds could have been present already in the common ancestor of dogs and wolves. We propose that their capacity to form at least some features of attachment with humans may stem from the ability to form social bond with pack members. This might have been then re-directed to humans during early domestication, providing the basis for the evolution of other socio-cognitive abilities in dogs.

Hand-reared wolves show similar, or stronger, attachment toward human caregivers compared to hand-reared dogs

Domesticated animals are generally assumed to display increased sociability towards humans compared to their wild ancestors. Dogs (Canis familiaris) have the ability to form lasting attachment, a social bond based on emotional dependency, with humans and it has specifically been suggested that this ability evolved post-domestication in dogs. Subsequently, it is expected that dogs but not wolves (Canis lupus), can develop attachment bonds to humans. However, while it has been shown that 16-weeks-old wolves do not discriminate in their expression of attachment behaviour toward a human caregiver and a stranger when compared to similar aged dogs, wolves at the age of eight weeks do. This highlights the potential for wolves to form attachment to humans, but simultaneously raises the question if this attachment weakens over time in wolves compared to dogs. Here we used the Strange Situation Test (SST) to investigate attachment behaviour expressed in hand-reared wolves and dogs toward a human caregiver at the age of 23 weeks. Both wolves and dogs expressed attachment toward a human caregiver. Surprisingly, wolves, but not dogs, discriminated between the caregiver and a stranger by exploring the room more in the presence of the caregiver compared to the stranger and greeting the caregiver more than the stranger. Our results thereby suggest that wolves can show attachment toward humans comparable to that of dogs at later developmental stages. Importantly, our results indicate that the ability to form attachment with humans did not occur post-domestication of dogs.

Exhibiting disorganised attachment: not even wrong?1

This chapter presents the controversial category ‘disorganised’ attachment as an exhibit to assess how research agendas get shaped and distorted by normative and habitual assumptions that drive the belief systems of the research community. This classification has come to prominence because of its alleged relationship with child abuse and abusive parenting. Yet, there is some considerable debate in the primary literature about what the classification really means. Indeed, for diagnostic purposes, the coding system for disorganised attachment is complicated, and the inter-coder reliability only marginal: not all observers can agree when they have seen a case of disorganised attachment behaviour. The important point here is that different accounts of the same phenomenon coexist; they are associated with different worldviews. This makes it important to understand the origins of theoretical ideas within the scientific community, and of the debates and controversies within that world.

Problematic Attachment to Social Media: Five Behavioural Archetypes

Today, social media play an important role in people’s daily lives. Many people use social media to satisfy their personal and social needs, such as enhancing self-image, acquiring self-esteem, and gaining popularity. However, when social media are used obsessively and excessively, behavioural addiction symptoms can occur, leading to negative impacts on one’s life, which is defined as a problematic attachment to social media. Research suggests that tools can be provided to assist the change of problematic attachment behaviour, but it remains unclear how such tools should be designed and personalised to meet individual needs and profiles. This study makes the first attempt to tackle this problem by developing five behavioural archetypes, characterising how social media users differ in their problematic attachments to them. The archetypes are meant to facilitate effective ideation, creativity, and communication during the design process and helping the elicitation and customisation of the variability in the requirements and design of behaviour change tools for combatting problematic usage of social media. This was achieved by using a four-phase qualitative study where the diary study method was considered at the initial stage, and also the refinement and confirmation stage, to enhance ecological validity.

Phenotypic plasticity more essential to maintaining variation in host-attachment behaviour than evolutionary trade-offs in a facultatively parasitic mite

A prevailing hypothesis for the evolution of parasitism posits that the fitness benefits gained from parasitic activity results in selection for and fixation of parasitic strategies. Despite the potential fitness advantage of parasitism, facultative parasites continue to exhibit genetic variation in parasitic behaviour in nature. We hypothesized that evolutionary trade-offs associated with parasitic host-attachment behaviour maintain natural variation observed in attachment behaviour. In this study, we used replicate lines of a facultatively parasitic mite, previously selected for increased host-attachment behaviour to test whether increased attachment trades off with mite fecundity and longevity, as well as the phenotypic plasticity of attachment. We also tested for potential correlated changes in mite morphology. To test for context-dependent trade-offs, mite fecundity and longevity were assayed in the presence or absence of a host. Our results show that selected and control mites exhibited similar fecundities, longevities, attachment plasticities and morphologies, which did not provide evidence for life history trade-offs associated with increased attachment. Surprisingly, phenotypic plasticity in attachment was maintained despite directional selection on the trait, which suggests that phenotypic plasticity likely plays an important role in maintaining attachment variation in natural populations of this facultative parasite.

The process by which executives unlearn their attachments in order to facilitate change

Unlearning an attachment has become a critical change competence for executives. Although attachment behaviour in the workplace is ubiquitous, there is a scarcity of empirical research on the processes executives follow in order to release their dysfunctional attachments to systems, routines, ideas, divisions and certain members of staff. By unlearning attachments, executives can embrace new concepts, methods and processes and thereby enable their organisations to be more competitive. This qualitative research investigated executives’ experiences of unlearning an attachment, through the pre-unlearning, unlearning and post-unlearning phases. A de jure model was formulated from concepts that emerged during the literature review and this model was the basis of in-depth interviews with 10 change experts and 10 executives who had unlearned attachments. The executives and change experts shared real-life experiences during each of the unlearning phases. The findings informed a de facto model of the experiences of executives unlearning their attachments. This process model makes a theoretical contribution by depicting the major types of attachments, influences on, processes of, actions required by and outcome of the executives’ unlearning. The model should contribute to change practitioners’ facilitation of executives’ unlearning processes and executives’ insights into their own attachments.
