Reduced prefrontal and increased subcortical brain functioning assessed using positron emission tomography in predatory and affective murderers

There appear to be no brain imaging studies investigating which brain mechanisms subserve affective, impulsive violence versus planned, predatory violence. It was hypothesized that affectively violent offenders would have lower prefrontal activity, higher subcortical activity, and reduced prefrontal/subcortical ratios relative to controls, while predatory violent offenders would show relatively normal brain functioning. Glucose metabolism was assessed using positron emission tomography in 41 comparisons, 15 predatory murderers, and nine affective murderers in left and right hemisphere prefrontal (medial and lateral) and subcortical (amygdala, midbrain, hippocampus, and thalamus) regions. Affective murderers relative to comparisons had lower left and right prefrontal functioning, higher right hemisphere subcortical functioning, and lower right hemisphere prefrontal/subcortical ratios. In contrast, predatory murderers had prefrontal functioning that was more equivalent to comparisons, while also having excessively high right subcortical activity. Results support the hypothesis that emotional, unplanned impulsive murderers are less able to regulate and control aggressive impulses generated from subcortical structures due to deficient prefrontal regulation. It is hypothesized that excessive subcortical activity predisposes to aggressive behaviour, but that while predatory murderers have sufficiently good prefrontal functioning to regulate these aggressive impulses, the affective murderers lack such prefrontal control over emotion regulation. © 1998 John Wiley & Sons, Ltd.     

Reduced orthographic learning in dyslexic adult readers: evidence from patterns of letter search

Visual letter search performance was investigated in a group of dyslexic adult readers using a task that required detection of a cued letter target embedded within a random five-letter string. Compared to a group of skilled readers, dyslexic readers were significantly slower at correctly identifying targets located in the first and second string position, illustrating significantly reduced leftward facilitation than is typically observed. Furthermore, compared to skilled readers, dyslexic readers showed reduced sensitivity to positional letter frequency. They failed to exhibit significantly faster response times to correctly detect target letters appearing in the most, compared to least, frequent letter position within five-letter words, and response times correlated with positional letter frequency only for the initial, and not the final, letter position. These results are compatible with the SERIOL (sequential encoding regulated by inputs to oscillations within letter units) model of orthographic processing proposed by Whitney and Cornelissen (2005). Furthermore, they suggest that dyslexic readers are less efficient than skilled readers at learning to extract statistical regularities from orthographic input.     

Contemporary Muslim Families: Research and Practice

This research project was undertaken to provide family professionals with the basic information necessary to work appropriately with Muslim families. The Muslim population represents 4–6 million people in the United States, yet it is significantly underrepresented in the family literature. Qualitative analysis of focus groups and interviews revealed multiple key findings. Emergent themes include an interest in gender respect rather than gender equity, the importance of extended family, the centralism of Islam in daily life and the qualified acceptance of professional interventions. Implications for practice are discussed.     

Religiosity and coping with loneliness

Loneliness is a universal experience which transcends age, sex, geography, and culture. Religion, and often one's religiosity, are known to affect one's approach to life, behaviour, and social involvement. The present, preliminary study aimed to explore whether coping with loneliness is influenced by one's religious observance. The present study focused on Israeli Jews. 250 participants identified themselves as Secular, Conservative, or Orthodox, by answering a 34-item yes/no questionnaire on loneliness. The three groups statistically significantly differed in their manner of coping with loneliness only on the Religion and Faith subscale, as hypothesized. Similar studies with people of other religious denominations could further highlight that issue.     

Environmental Visual Distraction during Retrieval Affects the Quality,Not the Quantity,of Eyewitness Recall

Eyewitnesses instructed to close their eyes during retrieval remember more correct, and fewer incorrect, visual and auditory details. These effects are assumed to arise because eye‐closure reduces distraction from the retrieval environment, and so increased environmental distraction should have the reverse effects. To test this idea, 48 participants witnessed a video clip before verbally answering questions about visual and auditory details in the presence of irrelevant visual distraction varying in amount and predictability. More distraction led to fewer correct and more incorrect visual and auditory details being recalled, but the predictability of the distraction had no effect. These findings suggest that environmental distraction impacts upon memory quality rather than quantity, a pattern that may be hard for interviewers to detect.

Collective interviewing of suspects

When people are interviewed about possible wrongdoing that has been committed in groups, they typically are interviewed separately. Yet, in several settings it would be more intuitive and convenient to interview suspects together. Importantly, such collective interviews could yield verbal cues to deception. This is the first deception experiment to investigate collective interviewing. Twenty-one pairs of truth tellers and 22 pairs of liars were interviewed pair-wise about having had lunch together in a restaurant. Given that truth tellers adopt a “tell it all” strategy in the interviews while, in contrast, liars prefer to keep their stories simple, we predicted that pairs of truth tellers would (i) interrupt and (ii) correct each other more, and would (iii) add more information to each other's answers than pairs of liars. The results supported these hypotheses. Theory-driven interventions to elicit more cues to deception through simultaneous interviewing are discussed.     

Conflicting interests and the creation of a “third space”; reply to commentary

This paper addresses how to be an available and responsive therapist to a controlling and narcissistically vulnerable young girl. It presents an overview of the treatment relationship and specific vignettes from sessions. The paper describes an impasse that posed a quandary: how to find a balance between staying in control of the treatment while being responsive to the kind of object the child needs the therapist to be—being empathic without being intrusive—and meeting her aggression without getting into a power struggle. The author discusses how asserting her subjectivity by playfully role-playing aspects of the patient, by spontaneously using humor, and by surviving her destructiveness allows the treatment to move forward. Trial and error, reflection on practice, and informed intuition contributed to the author's understanding of the child and of the transference. Various theoretical perspectives influenced the work.     

Volunteering to Help Conserve Endangered Species: An Identity Approach to Human–Animal Relationships

This study explores identity in providing voluntary help for endangered animal species. Identity is a cornerstone of social psychological explanations of helping behaviour but has not been understood in relation to human–animal relationships. Open‐ended questionnaires were administered to 111 volunteers working in a range of international conservation projects aimed at protecting endangered animals. Participants were asked their reasons for volunteering, choice of project, experiences and expectations. Thematic textual analysis explored common features across the dataset. Themes identified were identifying with animals, humans dominating nature and collective identity with the organization and fellow volunteers. The paper suggests social psychological knowledge about helping behaviour be applied to understand human–animal interactions to offer insight into the conditions under which we will engage with conservational and environmental concerns and provide aid. Social psychology has been slow to apply its knowledge to an examination of human responses to the challenge of loss of biodiversity. To act, humans must identify with those they seek to protect.

IV. Kierkegaard — some unfinished business

This note is in part a response to Alastair Hannay's review discussion, ‘A Kind of Philosopher: Comments in Connection with Some Recent Books on Kierkegaard’ (Inquiry, Vol. 18 [1975], No. 3). In his review, Hannay states that Kierkegaard and philosophy appear to be on the road to a reconciliation, and asks What is behind this get‐together if it is one?’. I suggest that in some remarks touching on Kierkegaard's theory of Truth, Hannay has touched on the ground for that ‘get‐together’, a Pyrrhonian scepticism.
