Conceptualizing Nonsuicidal Self‐Injury as a Process Addiction: Review of Research and Implications for Counselor Training and Practice

Nonsuicidal self‐injury (NSSI) may be characterized as a process addiction for some individuals who self‐injure. The authors review findings on the addictive features of NSSI, including compulsivity, loss of control, continued use despite negative consequences, and tolerance.     

Toward a Pragmatic Psychology

In this article I want to expand on the pragmatism that runs through Being Human: Human Being in order to think about what a pragmatic psychology might look like. Baert (2005) argued that a pragmatist science has to begin with an acknowledgment of the different interests that might be behind inquiry. The aims of inquiry are linked to useful and appropriate methods. I argue that in personality and social psychology the focus should primarily be on achieving hermeneutic understanding, rather than on finding causal explanation.     

Research digest: post-traumatic stress disorder

The onset of weaning is often described as an important early milestone, but it creates considerable emotional turbulence in the motherinfant relationship. The interruption of the breast-feeding relationship, whether gradual or sudden, creates a very special kind of agony for both the mother and baby, especially when a good trusting relationship with the breast has been found. This paper explores some of the hurts and sacrifices made on both sides during weaning, and looks at some of the subtle reactions to mutual feelings of rejection at this time. It also describes some of the difficulties that arise when the work of weaning is compromised by certain anxieties in the feeding relationship. Extracts from several psychoanalytical infant observations are used both to illustrate and to discuss these themes.     

Inhibition and the right inferior frontal cortex

It is controversial whether different cognitive functions can be mapped to discrete regions of the prefrontal cortex (PFC). The localisationist tradition has associated one cognitive function - inhibition - by turns with dorsolateral prefrontal cortex (DLPFC), inferior frontal cortex (IFC), or orbital frontal cortex (OFC). Inhibition is postulated to be a mechanism by which PFC exerts its effects on subcortical and posterior-cortical regions to implement executive control. We review evidence concerning inhibition of responses and task-sets. Whereas neuroimaging implicates diverse PFC foci, advances in human lesion-mapping support the functional localization of such inhibition to right IFC alone. Future research should investigate the generality of this proposed inhibitory function to other task domains, and its interaction within a wider network.     

Sales Force Motivation Using Travel Incentives: Some Empirical Evidence

This study examines the use of travel incentives as motivators for a commission only life insurance sales force in the United Kingdom. A sample of 1,083 sales representatives reported that travel is a strong motivator and valued more highly than several other types of incentives.     

The state,the institution,and the patient: A three-way collison at the crossroads as a hospital fights closure

This paper recounts the story of a National Health Service hospital which was almost closed for financial reasons in 1990. After a political campaign carried out in the full glare of publicity, the Hospital was reprieved. The account is based on the author's conversations with members of staff. The story of the staff, the patients, the Hospital, and the political struggle are woven together by common themes which are highlighted by reference to the Oedipus myth.     

Mandarin speech perception by ear and eye follows a universal principle

In this study, the nature of speech perception of native Mandarin Chinese was compared with that of American English speakers, using synthetic visual and auditory continua (from /ba/ to /da/) in an expanded factorial design. In Experiment 1, speakers identified synthetic unimodal and bimodal speech syllables as either /ba/ or /da/. In Experiment 2, Mandarin speakers were given nine possible response alternatives. Syllable identification was influenced by both visual and auditory sources of information for both Mandarin and English speakers. Performance was better described by the fuzzy logical model of perception than by an auditory dominance model or a weighted-averaging model. Overall, the results are consistent with the idea that although there may be differences in information (which reflect differences in phonemic repertoires, phonetic realizations of the syllables, and the phonotactic constraints of languages), the underlying nature of audiovisual speech processing is similar across languages.     

Reduced discriminability following perceptual learning with odours

In this experiment, the effects of prior experience on odour perception and discrimination were explored. Participants repeatedly sniffed a mixture composed of two odours, AX, as well as smelling two further odours alone, B and Y. After this training phase, participants were asked to rate the similarity of the odours A and X, B and Y, and a non-exposed pair C and Z. A and X were judged as significantly more alike than the other pairs. Exactly the same pattern emerged on a second test, in which participants were asked to select the odd odour out of sets of three. It was consistently harder for participants to pick the odd odour when the stimuli were drawn from the AX pair (eg A versus AX versus AX). Not only do these findings demonstrate that prior experience can affect odour perception, a finding not predicted by theories of odour perception based solely upon the physiochemical properties of odours, they also suggest that experience can act to selectively decrease discriminability.     

Cholinergic modulation of visual attention and working memory: dissociable effects of basal forebrain 192-IgG-saporin lesions and intraprefrontal infusions of scopolamine

Two experiments examined the effects of reductions in cortical cholinergic function on performance of a novel task that allowed for the simultaneous assessment of attention to a visual stimulus and memory for that stimulus over a variable delay within the same test session. In the first experiment, infusions of the muscarinic receptor antagonist scopolamine into the medial prefrontal cortex (mPFC) produced many omissions but did not impair rats' ability to correctly detect a brief visual stimulus. However, these animals were highly impaired in remembering the location of that stimulus following a delay period, although in a delay-independent manner. In the second experiment, another group of animals with selective 192IgG-saporin lesions of the nucleus basalis magnocellularis (nBM) were not impaired under conditions of low-attentional demand. However, when the stimulus duration was reduced, a significant memory impairment was observed, but similar to the results of the first experiment, the nBM-lesioned animals were not impaired in attentional accuracy, although aspects of attention were compromised (e.g., omissions). These findings demonstrate that (1) cortical cholinergic depletion produces dissociable deficits in attention and memory, depending on the task demands, (2) delay-independent mnemonic deficits produced by scopolamine are probably due to impairments other than simple inattention, and (3) working memory deficits are not simply dependent on attentional difficulties per se. Together, these findings implicate the nBM cortical cholinergic system in both attentional and mnemonic processing.     

The effectiveness of drug treatment programs in reducing criminal behavior: a meta-analysis

The main aim of this paper is to assess the effectiveness of drug treatment programs in reducing criminal behavior. The research is based on a systematic review and meta-analysis of evaluations of drug treatment programs. The research investigated various drug treatment programs including methadone treatment, therapeutic communities, post-release supervision for drug-misusing offenders, and drug courts, and focused on drug treatment programs that were primarily concerned with heroin, crack and cocaine misuse. The main outcome variable analyzed was reoffending following treatment as measured by self-reports or official records. The study was based on a meta-analysis of 28 evaluations of drug treatment programs. The meta-analysis involved calculating individual effect sizes for each study and weighted mean effect sizes for groups of studies. The mean odds of offending following treatment were significantly lower among clients of the drug treatment programs than among the comparison groups. However, the results varied by type of program, type of evaluation methods used, and characteristics of clients.
