Structural brain abnormalities in psychopaths-a review

The biological basis of psychopathy has not yet been fully elucidated. Few studies deal with structural neuroimaging in psychopaths. The aim of this article is to review these studies in order to contribute to our understanding of the biological basis of psychopathy. Data in the literature report a reduction in prefrontal gray matter volume, gray matter loss in the right superior temporal gyrus, amygdala volume loss, a decrease in posterior hippocampal volume, an exaggerated structural hippocampal asymmetry, and an increase in callosal white matter volume in psychopathic individuals. These findings suggest that psychopathy is associated with brain abnormalities in a prefrontal-temporo-limbic circuit-i.e. regions that are involved, among others, in emotional and learning processes. Additionally, data indicate that psychopathic individuals cannot be seen as a homogeneous group. The associations between structural changes and psychopathic characteristics do not enable causal conclusions to be drawn, but point rather to the important role of biological brain abnormalities in psychopathy. To gain a comprehensive understanding of this, psychopathy must be viewed as a multifactorial process involving neurobiological, genetic, epidemiological and sociobiographical factors.     

Infant crying and maternal holding in the first 2 months of age: an Italian diary study

This study aims to confirm previous North American and North European findings about the normal developmental pattern of infant crying by studying the crying of Italian babies. A cohort of 70 healthy, full‐term Italian infants was assessed longitudinally at 2, 5 and 8 weeks of age. Mothers were asked to fill in 24‐h behaviour diaries for 3 consecutive days at each age. Results show significant differences in the amount of daily crying between 2 and 8 weeks and between 5 and 8 weeks. Different from other similar studies, no significant cry peak at 5 weeks was found in the Italian babies, but the amount of time Italian mothers spent holding their babies showed a peak at 5 weeks. Infants cried more during the evenings and mothers carried them most during this part of the day. Significant correlations between maternal holding and infant crying were found both concurrently and predictively. The amount of infant crying at 2 weeks predicted the amount of holding at 5 weeks. Results confirmed previous findings about the individual stability of daily crying in the first 8 weeks of age, but future research should take account of cultural variations in maternal holding in studying infant crying in different societies.

Affective priming with subliminally presented pictures.

Affective priming studies have demonstrated that subliminally presented prime words can exert an influence on responses towards positive or negative target stimuli. In the present series of experiments, it was investigated whether these findings can be extended to pictorial stimuli. Ideographically selected positive, neutral, and negative picture primes that were sandwich-masked immediately preceded positive or negative target pictures (Experiment 1) or words (Experiments 2 & 3). Evaluative categorization responses to these target stimuli were significantly influenced by the valence of the prime. First, it was demonstrated that high anxious participants were selectively slowed when the subliminally presented prime was negative (Experiments 1 & 2). Second, the affective congruence between primes and targets also exerted an influence on the responses, but in a direction that is opposite to what is typically observed in affective priming research. These reverse priming effects are situated within a series of recent similar findings, and implications for theories of affective priming are discussed.     

Putting the brakes on prejudice rebound effects: An ironic effect of disparagement humor

When people high in prejudice censor prejudice in one setting, they can experience a prejudice rebound effect—subsequently responding with more prejudice than otherwise. Disparagement humor fosters the release rather than suppression of prejudice. Thus, two experiments tested the hypothesis that exposure to disparagement humor attenuates rebound effects. Participants suppressed prejudice by writing fewer anti-gay thoughts about same-sex adoption (Experiment 1) or by reporting greater support for same-sex civil rights (Experiment 2) when expecting to share their responses with others (non-prejudice norm condition) but not if others first exchanged anti-gay jokes (prejudice norm condition). High-prejudice participants then exhibited prejudice rebound in the non-prejudice norm condition only. They rated a gay man more stereotypically (Experiment 1) and allocated greater budget cuts to a gay student organization (Experiment 2) in the non-prejudice norm condition.     

The Theological Misappropriation of Christianity as a Civilizing Force

The theological misappropriation of Christianity as a civilizing force occurs when individuals convert to Christianity due to deception that ignores the faith-based aspect of Christianity. The history of Western education in India illustrates the hidden curriculum that Christian missionaries employed to disrupt the Indian educational system. This unnerving pedagogy points to the need for a postcolonial theoretical framework that relates the inescapable hybridity of religion and culture where Orientalism has the potential to occur. To press the ongoing urgency of this discussion, I convey how the history of British India connects to my lived-reality as an American Hindu. Overall, I point to hybridity as a lived paradox of ambiguous conflict that embraces interfaith relations. I offer implications for Christian missionaries today to foster authentic interfaith connections without engaging in colonizing ideologies.

Walking through doorways differentially affects recall and familiarity

Previous research has reported that walking through a doorway to a new location makes memory for objects and events experienced in the previous location less accurate. This effect, termed the location updating effect, has been used to suggest that location changes are used to mark boundaries between events in memory: memories for objects encountered within the current event are more available than those from beyond an event boundary. Within a computer‐generated memory task, participants navigated through virtual rooms, walking through doorways, and interacting with objects. The accuracy and their subjective experience of their memory for the objects (remember/know and confidence) were assessed. The findings showed that shifts in location decreased accurate responses associated with the subjective experience of remembering but not those associated with the experience of knowing, even when considering only the most confident responses in each condition. These findings demonstrate that a shift in location selectively impacts recollection and so contributes to our understanding of boundaries in event memory.     

On the replicability of the affective priming effect in the pronunciation task

Bargh, Chaiken, Raymond, and Hymes (1996) and Hermans, De Houwer, and Eelen (1994) showed that a valenced target word is pronounced faster after the presentation of an affectively related prime word than after the presentation of an affectively unrelated prime word. This finding is important because it provides crucial evidence for the hypotheses that stimulus evaluation (a) is goal-independent and (b) facilitates the encoding of stimuli that have the same valence. However, recent studies indicate that the affective priming effect is not a reliable finding in the standard pronunciation task. We report the results of a nearly exact replication of Bargh et al.'s (1996) Experiment 2. In line with previous replication studies, we failed to detect the affective priming effect.     

Autobiographical memory specificity and affect regulation: an experimental approach

This study investigated J. M. G. Williams's (1996) affect-regulation hypothesis that level of specificity of autobiographical memory (AM) is used to minimize negative affect. It was found that a negative event leads to more reports of subjective stress in high- as compared with low-specific participants. Also, afterward, high-specific participants rated their unprompted memories for the event as more unpleasant. The results indicate that, relative to high specificity, being less specific in the retrieval of AMs is associated with less affective impact of a negative event. Results are discussed within the affect-regulation model. It is suggested that future research take a more functional perspective on AM specificity.     

Psychoanalytic practice in the early postgraduate years

As a pilot investigation for a longitudinal study of psychoanalytic careers, a survey was conducted of analysts who graduated during the last fifteen years from the Columbia University Center for Psychoanalytic Training and Research. Graduates were asked to describe both their analytic practice and their interest in pursuing appointment as training and supervising analysts. The 23-item questionnaire was completed by 67 of 102 potential respondents (66%). The study identified two subgroups of graduates: those who were not certified and were not training analysts (GAs), 78% of the sample, and certified and training analysts (CAs, TAs), 22% of the sample. GAs started a mean of 1.4 new analytic cases since graduation, as compared to CAs and TAs, who started a mean of 5.4 and 8.3 new cases, respectively. CAs and TAs also saw more twice-weekly therapy cases than did GAs. Once-weekly therapy was the most commonly practiced treatment for all subgroups. Interest in becoming a TA was highest during the first five postgraduate years and was lower among non-TAs five to fifteen years after graduation. Only one of the CA respondents met current APsaA immersion criteria for training analyst appointment.
