Gender differences in comorbid disorders among offenders in prison substance abuse treatment programs

This study examined gender differences in a range of lifetime psychiatric disorders in a sample of 272 offenders newly admitted to a prison substance abuse program. Although these men and women did not differ in severity of substance use in the six months prior to incarceration, women were significantly more likely than men to report a lifetime psychiatric disorder and a lifetime severe disorder. Furthermore, gender differences emerged in the pattern of lifetime psychiatric comorbidity. Women reported greater lifetime major depression, posttraumatic stress disorder, eating disorder, and borderline personality disorder; men were more likely than women to meet criteria for antisocial personality disorder. Additionally, female offenders were found to have a higher degree of internalizing disorders than male offenders, but there were no gender differences in degree of externalizing disorders. The study concluded that women offenders newly admitted to a prison substance abuse program present with a greater psychiatric vulnerability and a different pattern of psychiatric comorbidity than their male counterparts.     

Communicative factors,conflict progression,and use of reconciliatory strategies in pre‐school boys‐a series of random events or a sequential process?

Affiliative interactions between former opponents soon after a conflict, in non‐human primates and pre‐school children, have been documented to be followed by a reduction of future aggression and stress reactions, and to promote tolerance between individuals. The phenomenon has, therefore, been called reconciliation. Studies of non‐human primates have shown that the conflict cause can influence the reconciliatory outcome, and whether the aggressor or the victim of the aggression is more likely to take the initiative to reconcile, can differ between species. Few studies in pre‐school children have addressed how factors preceding the post‐conflict period, such as social interactions before the conflict outbreak, or the cause of the conflict, may be related to the likelihood of reconciliation, conflict progression, and conflict outcome in the form of possible continuation or initiation of interactions. Twenty boys were video‐recorded during free‐play at six pre‐schools. The existence of social interaction between the opponents in the upcoming conflict was examined in the pre‐conflict period. The observed causes of conflict were determined and classified into five categories. The affiliative behaviors identified in the post‐conflict period were classified into six categories. Finally, whether or not conflicts were followed by communicative exchanges in the succeeding non‐conflict period was documented. The results revealed that the cause of the conflict is associated with whether opponents had established social interaction prior to conflict in the pre‐conflict period. Acceptance rates (for the various categories of affiliative behaviors) appeared to differ. A non‐random pattern of conflict progression was apparent, suggesting the conflict cause was related to the category of reconciliatory strategy shown by the individuals. The aggressor and the victim initiated reconciliation at similar rates, with the exception of verbal apologies, which were initiated most often by the aggressor. Finally, the data also showed that higher frequencies of social interaction between former opponents in the succeeding non‐conflict period were associated both with whether or not social interaction had occurred in the pre‐conflict period, and whether or not the conflict was reconciled. In conclusion, communicative factors preceding conflicts, and conflict cause, are distinctively correlated with both the use and the outcome of post‐conflict affiliation in pre‐school boys. Aggr.

A psychology of the human brain–gut–microbiome axis

In recent years, we have seen increasing research within neuroscience and biopsychology on the interactions between the brain, the gastrointestinal tract, the bacteria within the gastrointestinal tract, and the bidirectional relationship between these systems: the brain–gut–microbiome axis. Although research has demonstrated that the gut microbiota can impact upon cognition and a variety of stress‐related behaviours, including those relevant to anxiety and depression, we still do not know how this occurs. A deeper understanding of how psychological development as well as social and cultural factors impact upon the brain–gut–microbiome axis will contextualise the role of the axis in humans and inform psychological interventions that improve health within the brain–gut–microbiome axis. Interventions ostensibly aimed at ameliorating disorders in one part of the brain–gut–microbiome axis (e.g., psychotherapy for depression) may nonetheless impact upon other parts of the axis (e.g., microbiome composition and function), and functional gastrointestinal disorders such as irritable bowel syndrome represent a disorder of the axis, rather than an isolated problem either of psychology or of gastrointestinal function. The discipline of psychology needs to be cognisant of these interactions and can help to inform the future research agenda in this emerging field of research. In this review, we outline the role psychology has to play in understanding the brain–gut–microbiome axis, with a focus on human psychology and the use of research in laboratory animals to model human psychology.     

How Effective is the Enhanced Cognitive Interview when Aiding Recall Retrieval of Older Adults including Memory for Conversation?

The percentage of older adults in the general population is growing. As a result, older adults are coming more frequently into contact with the Criminal Justice System as witnesses to and victims of crime. Older adults are also over‐represented in crimes where conversation detail is of particular importance to an investigation (e.g. distraction burglary). The present study therefore examined the efficacy of cognitive interview (CI) compared with structured interview in improving the recall of an event by older witnesses, specifically conversational detail. Young adults (19–54 years old), young‐old adults (60–74 years old), and old‐old adults (75+ years old) were asked to watch a short film of a laptop theft and were then, after a 1.5 hour delay, randomly allocated to one of two interview conditions. It was found that the CI significantly increased recall of all age groups, without increasing the amount of incorrect or confabulated information reported. The individuals in the young adult and the young‐old adult conditions were found to remember significantly more than the individuals from the old‐old adult condition, without decreasing the accuracy of the information. The CI enhanced memory for conversation gist, person and action detail. Results will be discussed in relation to interviewing and investigating practices.

The N400 effect in children: relationships with comprehension, vocabulary and decoding

Using event-related potentials (ERPs), we investigated the N400 (an ERP component that occurs in response to meaningful stimuli) in children aged 8-10 years old and examined relationships between the N400 and individual differences in listening comprehension, word recognition and non-word decoding. Moreover, we tested the claim that the N400 effect provides a valuable indicator of behavioural vocabulary knowledge. Eighteen children were presented with picture-word pairs that were either ‘congruent’ (the picture depicted the spoken word) or ‘incongruent’ (they were unrelated). Three peaks were observed in the ERP waveform triggered to the onset of the picture-word stimuli: an N100 in fronto-central channels, an N200 in central-parietal channels and an N400 in frontal, central and parietal channels. In contrast to the N100 peak, the N200 and N400 peaks were sensitive to semantic incongruency with greater peak amplitudes for incongruent than congruent conditions. The incongruency effects for each peak correlated positively with listening comprehension but when the peak amplitudes were averaged across congruent/incongruent conditions they correlated positively with non-word decoding. These findings provide neurophysiological support for the position that sensitivity to semantic context (reflected in the N400 effect) is crucial for comprehension whereas phonological decoding skill relates to more general processing differences reflected in the ERP waveform. There were no correlations between ERP and behavioural measures of expressive or receptive vocabulary knowledge for the same items, suggesting that the N400 effect may not be a reliable estimate of vocabulary knowledge in children aged 8-10 years.
