Mirror pecking and timeout under a multiple fixed-ratio schedule of food delivery

Pigeons were trained to peck a key under a multiple fixed-ratio 25 fixed-ratio 175 schedule of food presentation. In the first condition, either a mirror or the opportunity to produce a 30-second timeout were available. In a second condition, mirror and timeout availability were reversed for the two groups. Following a return to the initial condition, mirror and timeout keys were presented together for all birds. Mirror and timeout responses occurred predominantly in the pause in the larger fixed-ratio component, regardless of whether the opportunities for the two responses were available singly or together. Mirror responding occurred in a greater proportion of the pauses than did timeouts. When the opportunities for both mirror pecking and timeout were available concurrently, they occurred with probabilities similar to those under the single conditions. Within the pause itself, mirror responses most frequently occurred immediately after reinforcement. Timeouts occurred most frequently toward the end of the pause, and some timeouts occurred in the early part of the run. Longer preratio pausing occurred in the larger fixed-ratio component in the conditions in which the mirror was present, whether or not any mirror pecks were recorded.     

Dating violence in the United Kingdom: A preliminary study

A small-scale study of “dating violence” in a sample of UK college students is described. Methodology involved the rating-scale used in existing US studies, with the addition of an assessment of inter-respondent reliability, which was found to be high. A high incidence of some form of violence was found, with women showing higher levels than men, thus replicating previous US findings based on victim reports. Violence in the present relationship was found to be unrelated to violence in past relationships.     

个人奋斗及其相关研究

个人奋斗作为个人目标概念中最有代表性的一种,是一种特定的、与情境目标有关的人格意向结构,指的是个体通过日常行为所努力达成的特性生活目标。根据目标理论的层次结构,个人奋斗及类似概念被统称为人格中的“中层”目标单元。文章选取Emmons的个人奋斗理论,从个人奋斗的基本概念及其测评开始,论述其与幸福感、人格特质的相关关系,并简要评述了几种不同的个人目标理论,呈现了一种与传统特质理论不同的人格研究方法     

The Implications of "Martyrdom Operations" for Contemporary Islam

This article explores the implications of the prevalence of suicide attacks or ‘martyrdom operations’ in contemporary Islam. Historical and legal precedents from Islam and Christianity are adduced for the analysis and placed within the context of radical Islam.     

Genetic and Environmental Influences on Personal and Rhythmic‐Motor‐Activity Tempo in Children: A Twin Study

In this study, we investigated the degree to which genetics and environmental factors influence the tempo and tempo stability of rhythmic motor activity in young children, using a twin study design. A total of 116 twin children, aged 4 years, were asked to strike two small clash cymbals together in a cyclical manner, in three phases. In the first phase, children were asked to maintain a comfortable personal tempo of rhythmic motor activity (spontaneous motor phase). In contrast, in the other phases, children were required to synchronize rhythmic motor activity in response to the timing of a stimulus tone, or a memorized tempo. Large additive genetic, although negligible shared environmental influences, were observed in the spontaneous motor phase. However, environmental factors were estimated in the other two phases, while the additive genetic factor was nearly zero. These results indicate that the extent of genetic and environmental influences on individual differences in rhythmic motor activity can be modulated under different situations.     

Factors contributing to individual differences in facial expression categorisation

Individuals vary in perceptual accuracy when categorising facial expressions, yet it is unclear how these individual differences in non-clinical population are related to cognitive processing stages at facial information acquisition and interpretation. We tested 104 healthy adults in a facial expression categorisation task, and correlated their categorisation accuracy with face-viewing gaze allocation and personal traits assessed with Autism Quotient, anxiety inventory and Self-Monitoring Scale. The gaze allocation had limited but emotion-specific impact on categorising expressions. Specifically, longer gaze at the eyes and nose regions were coupled with more accurate categorisation of disgust and sad expressions, respectively. Regarding trait measurements, higher autistic score was coupled with better recognition of sad but worse recognition of anger expressions, and contributed to categorisation bias towards sad expressions; whereas higher anxiety level was associated with greater categorisation accuracy across all expressions and with increased tendency of gazing at the nose region. It seems that both anxiety and autistic-like traits were associated with individual variation in expression categorisation, but this association is not necessarily mediated by variation in gaze allocation at expression-specific local facial regions. The results suggest that both facial information acquisition and interpretation capabilities contribute to individual differences in expression categorisation within non-clinical populations.     

So many lifetimes locked inside: reflecting on the use of music and songs to enhance learning through emotional and social connection in Trainee Clinical Psychologists

Music is universal; it can provide a common language that speaks from the heart enabling others to connect with the private felt experiences of others regardless of differences within or between people. This ability to empathise with, and understand, the position of others from differing backgrounds is an important competency within the therapeutic work of Clinical Psychologists. There are many facets to diversity just as there are many facets to music. Diversity in music genres can reflect diversity in people. Indeed, there is music to cater for all tastes, cultural/ethnic backgrounds, gender, age and generations with listening often being guided by individual preferences. In the United Kingdom training to become a Clinical Psychologist consists of a university-based 3-year full time professional research doctorate funded through the National Health Service. Trainees work on placements 3 days a week and attend university for academic and research teaching 2 days a week. As part of the academic programme, Trainees undertake experiential learning through workshops and methods such as Problem-Based Learning (PBL). One of the PBL exercises is based on a typical referral within an Adult Mental Health (AMH) service. For the AMH PBL exercise music is used to enhance trainees’ ability to connect emotionally with the personhood of referrals, consider associated complexities, and to reflect on personal and professional boundaries and reflective practice during training and beyond. This paper reflects on the utility of music and songs to enhance the learning experience.     

Conceptions of love in Ghana: An exploration among Ghanaian Christians

We explored conceptions of love from the perspective of Ghanaian Christians. Using an ethnographic approach, we interviewed 61 participants (males = 39; females = 22; age range 20 to 70) on their understanding and experiences of love in the context of family. Thematic analysis of the interview data revealed understandings of love expression in meeting material needs (of children, spouse, parents, and close relatives), helping other people in need (including the elderly, friends, and strangers), and affectionate care. Communal and maintenance-oriented love appears to characterise love expression among Ghanaian Christians.
