Rape and sexual assault in investigative psychology: the contribution of sex offenders' research to offender profiling

Research on sex offenders has mainly guided clinical practice for risk assessment and therapeutic intervention. However, the current scientific knowledge on these offenders and their crimes is, in many aspects, of great importance to criminal investigations. Consequently, there is a need to build bridges between investigative psychology and the research being conducted on sex offenders. Four areas of research on sex offenders that have clear implications to investigative psychology can be identified: (1) the consistency or ‘crime‐switching’ patterns of sex offenders; (2) the recidivism patterns of different types of sex offenders; (3) the police response to specific victim characteristics; and (4) the A → C equation of sexual assaults. This paper argues for a need to establish a dialogue between these two fields of research so that knowledge about sex offenders keeps growing whilst being able to inform policing practices in investigative psychology.

The HoST programme: A pilot evaluation of modified dialectical behaviour therapy with female offenders diagnosed with borderline personality disorder

The Holloway skills therapy programme (HoST) at Her Majesty’s Prison and Young Offenders’ Institution Holloway is provided to women who, because of problematic behaviour associated with borderline personality disorder, are often excluded from treatment in prison and in the community. HoST addresses issues of offending behaviour, self-harm, suicidality and indiscipline, through a modified evidence-based treatment modality, dialectical behaviour therapy (DBT), which is a form of cognitive behaviour psychotherapy. This paper will outline the possibility of a modified DBT approach to working with female offenders in the prison setting. A pilot evaluation of female prisoners who received the treatment is also presented through a range of quantitative measures. In turn, positive outcomes with regard to reduction in time spent on the assessment and care in custody teamwork process, reduction in adjudications and improved overall mental health are presented. These findings are discussed along with the implications for clinical practice in the prison setting. The need for future structured research is also discussed.     

Eye movements and parafoveal preview of compound words: Does morpheme order matter?

Recently, there has been considerable debate about whether readers can identify multiple words in parallel or whether they are limited to a serial mode of word identification, processing one word at a time (see, e.g., Reichle, Liversedge, Pollatsek, & Rayner, 2009). Similar questions can be applied to bimorphemic compound words: Do readers identify all the constituents of a compound word in parallel, and does it matter which of the morphemes is identified first? We asked subjects to read compound words embedded in sentences while monitoring their eye movements. Using the boundary paradigm (Rayner, 1975), we manipulated the preview that subjects received of the compound word before they fixated it. In particular, the morpheme order of the preview was either normal (cowboy) or reversed (boycow). Additionally, we manipulated the preview availability for each of the morphemes separately. Preview was thus available for the first morpheme only (cowtxg), for the second morpheme only (enzboy), or for neither of the morphemes (enztxg). We report three major findings: First, there was an effect of morpheme order on gaze durations measured on the compound word, indicating that, as expected, readers obtained a greater preview benefit when the preview presented the morphemes in the correct order than when their order was reversed. Second, gaze durations on the compound word were influenced not only by preview availability for the first, but also by that for the second morpheme. Finally, and most importantly, the results show that readers are able to extract some morpheme information even from a reverse order preview. In summary, readers obtain preview benefit from both constituents of a short compound word, even when the preview does not reflect the correct morpheme order.     

The internet and its role in the escalation of sexually compulsive behaviour

As increasing numbers of patients present with problems of compulsive use of internet sex and internet pornography, psychotherapists are challenged to develop models that address the powerful, and potentially disturbing effect of this stimulus. Internet sex does not just facilitate access to sexual materials but can act as a catalyst, affecting established defences and ego and superego functioning. Escalation in sexually compulsive behaviour, which affects a small proportion of those accessing online sex, may be thought of as a series of transitions: from casual to compulsive use, from compulsive use to illegal use, and from use of illegal pornography to contact offending. Drawing on clinical experience and the available research evidence, psychodynamic processes associated with movement through these transitions are considered. Internet sex has the potential to fuel manic defences, invites narcissistic and part-object relating, provides a vehicle for the expression and disowning of sadistic impulses and can potentially undermine superego functioning. The combined effect of these processes may lead to a breakdown of ego controls in vulnerable individuals.     

Emotion and culture: A meta-analysis

A meta-analysis of 190 cross-cultural emotion studies, published between 1967 and 2000, was performed to examine (1) to what extent reported cross-cultural differences in emotion variables could be regarded as valid (substantive factors) or as method-related (statistical artefacts, cultural bias), and (2) which country characteristics could explain valid cross-cultural differences in emotion. The relative contribution of substantive and method-related factors at sample, study, and country level was investigated and country-level explanations for differences in emotions were tested. Results indicate that a correction for statistical artefacts and method-related factors reduced the observed cross-cultural effect sizes considerably. After controlling for valence (positive vs. negative emotions) and kind of study (self-report vs. recognition studies), the remaining cross-cultural variance was associated with subsistence mode, political system, values, and religiosity. Values explained more variance than did ecological or sociopolitical variables. It was concluded that both method-related factors (13.8% of variance explained) and culture-level factors (27.9% of variance explained) underlie observed cross-cultural differences.     

Serial position-dependent false memory effects*

ABSTRACT

Evidence for false recognition within seconds of encoding suggests that semantic-associative influences are not restricted to long-term memory, consistent with unitary memory accounts but contrary to dual store models. The present study sought further relevant evidence using a modified free recall converging associates task where participants studied 12-item lists composed of 3 semantically distinct quartets (sublists) related to a separate, non-presented theme word (i.e., words 1–4/theme1, 5–8/theme2, and 9–12/theme3). This list construction permits assessment of false recall errors from each sublist, and, particularly, the primacy and recency sublists that have been linked to long- and short-term memory stores. Experiment 1 tested immediate free recall for items. Associative false memories were evident from all sublists, however, significantly less so from the recent sublist, which also showed the highest levels of veridical memory. By inserting a brief (3?s) distractor prior to recall, Experiment 2 selectively reduced veridical memory and increased false memory for the recent sublist while leaving the primacy sublist unaffected. These recall results converge with prior evidence indicating the immediacy of false recognition, and can be understood within a unitary framework where the differential availability of verbatim features and gist-based cues affect memory for primacy and recency sublists.     

Do children use different forms of verbal rehearsal in serial picture recall tasks? A multi-method study

ABSTRACT

Use of verbal rehearsal is a key issue in memory development. However, we still lack detailed and triangulated information about the early development and the circumstances in which different forms of rehearsal are used. To further understand significant factors that affect children’s use of various forms of rehearsal, the present study involving 108 primary school children adopted a multi-method approach. It combined a carefully chosen word length effect method with a self-paced presentation time method to obtain behavioural indicators of verbal rehearsal. In addition, subsequent trial-by-trial self-reports were gathered. Word length effects in recall suggested that phonological recoding (converting images to names – a necessary precursor for rehearsal) took place, with evidence of more rehearsal among children with higher performance levels. According to self-paced presentation times, cumulative rehearsal was the dominant form of rehearsal only for children with higher spans on difficult trials. The combined results of self-paced times and word length effects in recall suggest that “naming” as simple form of rehearsal was dominant for most children. Self-reports were in line with these conclusions. Additionally, children used a mixture of strategies with considerable intra-individual variability, yet strategy use was nevertheless linked to age as well as performance levels.     

Music Training and Semantic Clustering in College Students

College students with 5 or more years of music training recalled significantly more words from a 16-item word list than did students with 0-4 years of training. The superior recall of the extensively trained students linked to better application of a semantic-clustering strategy across a series of 3 test trials. Music education and language experience may have similar influences on the development of verbal memory.     

Amplitude Scaling Compensates for Serial Delays in Correcting Eye and Arm Movements

Spatial and metrical parameters of the eye and arm movements made by human subjects (N = 7) in response to visual targets that were stepped unexpectedly either once (single step) or twice (double step) were studied. For the double-step, the displacement of a visual target was decreased or increased in amplitude at intervals before and during a movement. Provided the second target step occurred more than 100 ms before the onset of movement, the amplitude of the subjects' first response was altered in the direction of the new target location. But this amplitude scaling was not always sufficient to reach the new target location, and a second corrective response was required. The latency in producing this second response was greatly increased above reaction time latencies of movements to single-step targets, especially when the target change occurred 100 ms or more before movement onset. These findings suggest that even though serial processing limitations delay the production of a second corrective response, continuous parallel processing of visual information enables the amplitude of the first response to be altered with minimal delay. This enables some degree of real-time continuous control by the visuomotor control system.     

Gender constructions from a project on sex offenders

Abstract

The four-year group therapy of 16 sex offenders in prison was videotaped, and 21 sessions were carefully transcribed and analysed by means of conversation analysis and analysis of metaphor and narration. These qualitative methods are apt for verbal data and can be combined with psychoanalytic thinking in a productive way. New forms of process analysis can be developed. The results presented here are selected to relate to the topic of how the imprisoned group therapy participants constructed “gender” by ways of speaking about themselves, women, and their victims, young girls. The results show that it would be a mistake to think of these ways of speaking as if they could be ignored in favour of “deeper” motives, lying “behind” the words. Our results show how unconscious constructions of gender are not beyond language, but in language. “Doing gender” is a conversational practice.
