The Role of Memory Distrust in Cases of Internalised False Confession

This paper reviews the literature on the role of ‘memory distrust’ in cases of internalised false confessions and provides a heuristic model for understanding the antecedents and mechanism involved. It also provides an in‐depth analysis of two real life cases of ‘suspected’ murders involving six convicted persons, five of whom showed evidence of profound memory distrust regarding the alleged offences. The key factors were coercive interviewing, lengthy solitary confinement, contamination, psychological vulnerabilities (both state and trait) and lack of independent support during questioning. The vulnerabilities in such cases typically involve a combination of cognitive (memory flaws, lack of confidence in memory and failure to invoke distinctiveness heuristic), personality (suggestibility and compliance), health problems and motivational (desire and willingness to assist the police) factors. The two cases suggest that the process of internalised false confessions may be conceptualised in terms of five sequential steps: a trigger, plausibility, acceptance, reconstruction and resolution.

The relationship of compliance with inattention and hyperactivity/impulsivity

The aim of the study was to investigate the relationship between Attention Deficit Hyperactivity Disorder (ADHD) inattention and hyperactivity/impulsivity symptoms in predicting compliance. It was hypothesised that inattention symptoms are a better predictor of compliance than hyperactivity/impulsivity. There were two different groups of participants: 367 college students (both males and females) and 89 male prisoners. All participants had completed the Gudjonsson Compliance Scale (GCS) and the DSM-IV-TR (Screening) Checklist for adult ADHD symptoms. Significant correlations emerged between compliance and ADHD symptoms, but the correlations were higher for inattention than hyperactivity/impulsivity among both samples. This was confirmed by multiple regression analyses (hierarchical), which showed that the variance in compliance explained by ADHD inattention versus hyperactivity/impulsivity symptoms increased from 2% to 8% for college students and 8% to 24% for prisoners after entering inattention into the model (hyperactivity/impulsivity was entered first in the regression models). The findings suggest that inattention is a more powerful predictor of compliance than hyperactivity/impulsivity. This is a novel and an important finding.     

Compliance and personality: the vulnerability of the unstable introvert

The aim of the study was to assess the relationship of compliance with Eysenck's three personality dimensions: psychoticism, extraversion, and neuroticism. Three groups of participants (prison inmates, college students, and university students) completed the Gudjonsson Compliance Scale (GCS) and the Eysenck Personality Questionnaire (EPQ). As predicted, compliance correlated positively with neuroticism and negatively with extraversion in all groups, whereas for psychoticism the correlation was positive among the prison inmates, negative for college students, and non‐significant for university students. A quadrant analysis according to Eysenck's original two‐dimensional framework (neuroticism–stability and introversion–extraversion) showed that compliance was highest among unstable introverts and lowest among stable extraverts. The findings are discussed in relation to recent work on person‐type approaches. Copyright © 2004 John Wiley & Sons, Ltd.     

A quantitative review of overjustification effects in persons with intellectual and developmental disabilities

The overjustification hypothesis suggests that extrinsic rewards undermine intrinsic motivation. Extrinsic rewards are common in strengthening behavior in persons with intellectual and developmental disabilities; we examined overjustification effects in this context. A literature search yielded 65 data sets permitting comparison of responding during an initial no‐reinforcement phase to a subsequent no‐reinforcement phase, separated by a reinforcement phase. We used effect sizes to compare response levels in these two no‐reinforcement phases. Overall, the mean effect size did not differ from zero; levels in the second no‐reinforcement phase were equally likely to be higher or lower than in the first. However, in contrast to the overjustification hypothesis, levels were higher in the second no‐reinforcement phase when comparing the single no‐reinforcement sessions immediately before and after reinforcement. Outcomes consistent with the overjustification hypothesis were somewhat more likely when the target behavior occurred at relatively higher levels prior to reinforcement.     

Social and non‐social measures of cognition for predicting self‐reported and informant‐reported functional outcomes in early psychosis

The main aim of this study was to investigate the individual contributions of neurocognitive and social‐cognitive domains to self‐reported and informant‐reported functional outcome in early psychosis. We also sought to further characterize the nature of cognitive impairments in this sample and explore the interrelationships between the social‐cognitive measures and how they correlate with measures of neurocognition and clinical symptoms. In this study, 70 patients (mean age: 24.1; 87.1% males) with primary psychotic disorder diagnosed in the previous 5 years were assessed on multiple neurocognitive (processing speed, attention, working memory, immediate verbal memory, delayed recall, visual reasoning, inhibition, planning, cognitive flexibility), and social‐cognitive domains (theory of mind (ToM), emotion recognition, attributional style, metacognitive overconfidence) as well as measures of clinical symptoms. Functional outcome was assessed with three self‐reports and two informant‐reports. On average, patients performed one or more SD below healthy controls on measures of delayed recall, ToM and metacognitive overconfidence. Emotion recognition and ToM were intercorrelated and correlated with multiple neurocognitive domains and negative symptoms. Attributional style correlated with positive symptoms. In the context of multiple variables, self‐reported functional outcomes were predicted by attributional style, whereas emotion recognition and immediate verbal memory predicted variance in informant‐reported community functioning. These results support the suggestion of a likely distinction between the predictive factors for self‐reported and informant‐reported functional outcome in early psychosis and suggest that consideration of self‐assessment of functional outcome is critical when attempting to evaluate the effects attributional style has on functional disability.     

Forensic psychology in Iceland: a survey of members of the Icelandic Psychological Society

Forensic psychology is a rapidly growing specialism within psychology. A survey was carried out among the 152 members of the Icelandic Psychological Society (Sálfradingafélagi Islands) about their involvement and role in court work. Out of 101 psychologists who responded to the survey, 39 reported having been involved in court work, of whom 34 had testified in court. The great majority of court work of the psychologists involved assessments relating to child-care and custody proceedings, but there was evidence that Icelandic psychologists are increasingly becoming involved in criminal cases concerning criminal responsibility and the reliability of testimony. They are working much more independently of medical colleagues than before.     

Drug use as consumer behavior

Seeking integration of drug consumption research by a theory of memory function and emphasizing drug consumption rather than addiction, Müller & Schumann (M&S) treat drug self-administration as part of a general pattern of consumption. This insight is located within a more comprehensive framework for understanding drug use as consumer behavior that explicates the reinforcement contingencies associated with modes of drug consumption.     

The relationship of confabulation to the memory,intelligence, suggestibility and personality of prison inmates

This study investigates the relationship of confabulation to memory, intelligence, suggestibility and personality, as measured by the Eysenck Personality Questionnaire and the Gough Socialisation Scale. The subjects were 255 Icelandic prison inmates. Confabulation was measured from the memory narrative of the Gudjonsson Suggestibility Scale (GSS 1). The two components of confabulation—distortions and fabrications—were scored and analysed separately. Distortions and fabrications correlated poorly with each other. Furthermore, the confabulation scores correlated very poorly with the other psychological variables. The only positive correlations were a positive relationship with GSS Shift and a negative relationship with intelligence.
