The use of imagery in cognitive therapy for psychosis: A case example

There has been a long tradition of studying imagery in relation to psychotic symptoms. Recent studies have suggested that imagery may be involved in the development and maintenance of psychotic symptoms (hallucinations and delusions in particular). Following a review of this literature, including work conducted by the author and colleagues, a case study is used to illustrate the clinical applications of this work. Working with images that were associated with persecutory delusions appeared to contribute to a reduction in distress, preoccupation, and conviction in relation to these beliefs, which were assessed using a standardised measure (PSYRATS). The implications for theory, practice, and future research are considered.     

Memory-enhancing characteristics of client-recalled important events in cognitive and experiential therapy: Integrating cognitive experimental and therapeutic psychology

In an attempt to encourage further integrative theorizing and experimental work across cognitive and therapeutic psychology, characteristics of therapeutic events that might contribute to their ‘memorableness’ were examined. Scales that rate five ‘information processing’ characteristics of therapeutic events were employed to score such characteristics of 55 client-identified important and 55 matched control events taken from actual therapeutic sessions of both cognitive and experiential psychotherapies. Results indicated that scales scoring the ‘depth’, ‘elaborateness’, and ‘conclusion-orientation’ of therapeutic dialogue during the events examined tended to discriminate reliably and as predicted between client-identified important and control events, particularly when ratings of therapist talking turns were examined. Limited support also was found for a second prediction based on Paivio's (1986) dual coding theory of memory concerning different patterns of results for cognitive versus experiential therapeutic events. Suggestions are offered for further research on human memory for specific events in therapeutic and other areas of applied psychology.

Group cognitive behavioural therapy for depression outcomes predicted by willingness to engage in homework, compliance with homework, and cognitive restructuring skill acquisition

There is a need to understand the mechanism through which homework contributes to clinically meaningful change in therapy. Theoretically meaningful factors such as willingness to complete therapeutic assignments and cognitive skill acquisition have not been carefully studied in prior research. Depressed outpatients (N = 46) received cognitive behavioural group therapy for a 10-week period and were assigned relevant homework activities. Patient self-report and independent ratings of homework compliance were obtained on a session-by-session basis. Using path analysis, the authors found evidence that willingness to complete homework assignments and mastery of skill in cognitive restructuring helped account for the relationship between homework compliance and reduced symptom severity (R2 = .40). However, paths were only significant when patient self-report of homework compliance was used in the model. The present study highlights the problems in assessing homework compliance and in assuming that independent assessment of compliance is more accurate than patient self-report.     

Understanding cognitive,affective, and intimacy deficits in sexual offenders: A developmental perspective

Factors, such as intimacy deficits, problems empathizing with victims, and cognitive distortions, have all been associated with the genesis of sexual abuse. Importantly, they all point to a lack of awareness of other peoples' beliefs, desires, perspectives, and needs. We argue that sexual offenders' problems in these domains can be viewed as partially arising from deficits in one central mechanism: the ability to infer mental states. Following a review of the above three areas, we discuss the developmental literature on children's theory of mind and develop a model informed by this work. We apply this model to sexual offenders and discuss its research and clinical implications.     

A comparison of cognitive restructuring and cognitive defusion as strategies for resisting a craved food

The present study investigated the effectiveness of two cognitive strategies for resisting a craved food. One-hundred-and-ten self-identified chocolate cravers were randomised to a waiting list control condition or to receive a 60-minute standardised group intervention on cognitive restructuring (CR) or cognitive defusion (CD). All participants were provided with a bag of chocolates which they were instructed to carry with them for seven days and try to resist eating; uneaten chocolates were returned at the end of the study period. Measures included chocolate consumption and other behavioural, cognitive and evaluative self-reported outcomes. Overall, the odds of abstinence from chocolate were 3.26 times higher for participants in the CD than the CR condition. The effect of the interventions depended on baseline cognitive distress levels; for individuals at high levels of cognitive distress the CD condition led to significantly more restraint from chocolate than both the CR and control conditions. In addition, CD led to greater self-reported improvements in eating behaviours during the study period and was rated significantly easier to use and apply than CR. CD is discussed as a simple and efficient approach to manage food cravings and, potentially, other behavioural contributors to obesity.     

Value systems for developmental cognitive robotics: A survey

This paper surveys value systems for developmental cognitive robotics. A value system permits a biological brain to increase the likelihood of neural responses to selected external phenomena. Many machine learning algorithms capture the essence of this learning process. However, computational value systems aim not only to support learning, but also autonomous attention focus to direct learning. This combination of unsupervised attention focus and learning aims to address the grand challenge of autonomous mental development for machines. This survey examines existing value systems for developmental cognitive robotics in this context. We examine the definitions of value used—including recent pioneering work in intrinsic motivation as value—as well as initialisation strategies for innate values, update strategies for acquired value and the data structures used for storing value. We examine the extent to which existing value systems support attention focus, learning and prediction in an unsupervised setting. The types of robots and applications in which these value systems are used are also examined, as well as the ways that these applications are evaluated. Finally, we study the strengths and limitations of current value systems for developmental cognitive robots and conclude with a set of research challenges for this field.     

Ghosts, UFOs, and magic: positive affect and the experiential system

Three studies examined the potential interactions of the experiential system and positive affect (PA) in predicting superstitious beliefs and sympathetic magic. In Study 1, experientiality and induced positive mood interacted to predict the emergence of belief in videos purporting to show unidentified flying objects or ghosts. In Study 2, naturally occurring PA interacted with experientiality to predict susceptibility to sympathetic magic, specifically difficulty in throwing darts at a picture of a baby (demonstrating the law of similarity). In Study 3, induced mood interacted with experientiality to predict sitting farther away from, and expressing less liking for, a partner who had stepped in excrement (demonstrating the law of contagion). Results are interpreted as indicating that PA promotes experiential processing. Implications for the psychology of nonrational beliefs and behaviors are discussed.     

Logical reasoning,world knowledge,and mental imagery: Interconnections in cognitive processes

To better understand the role of problem content in verbal reasoning, the effect of two aspects of problem representation on conditional reasoning was examined. Specifically, this study focused on the effect of availability of knowledge schemata and mental imagery on recognition of indeterminacy. Four groups of 20 adults solved syllogisms that varied in imagery value and in tendency to access knowledge schemata (assessed by ratings of the relatedness of antecedent and consequent clauses of premises). When problems both were high in imagery value and had related clauses, performance was significantly better on indeterminate syllogisms. Access to schemata may permit elaborative processing and the generation of counterexamples to invalid inferences; imagery may support representation of problems and generation of elaborative information in memory.     

A review of the impact of hypnosis,relaxation, guided imagery and individual differences on aspects of immunity and health

This review considers psychological interventions involving relaxation and guided imagery targeting immune functions. The review provides evidence of immune control accompanied by reports of enhanced mood and well-being. Three recent investigations of the author and his colleagues with self-hypnosis training incorporating imagery of the immune system are outlined. In two studies, hypnosis buffered the effects of stress on immune functions in medical students at exam time, and the comparison of self-hypnosis with and without immune imagery confirmed advantages to targeted imagery for both immune function and mood, and importantly, fewer winter viral infections. The implications for health were investigated in a third study in patients with virulent and chronic herpes simplex virus-2 HSV-2). Six weeks of training almost halved recurrence, improved mood and reduced levels of clinical depression and anxiety. Immune functions were up-regulated, notably functional natural killer cell activity to HSV-1. Individual differences in hypnotic susceptibility and absorption have typically been found to predict efficacy. New replicable evidence is reviewed of the importance of cognitive activation, a personality difference whose neurophysiological underpinning is consistent with left hemispheric preferential influences over the immune system. Now that the validation of psychological interventions includes advantages for health, this field of enquiry, which has been characterised by modest, small scale, largely preliminary studies, warrants a greater investment in research.     

Long-term family therapy: A developmental approach

The emphasis in family therapy literature on brief therapy has given a false sense of what family therapy can accomplish. While it has helped to develop different theories of change and refine techniques to deal with resistance, it has caused many clinicians to mistake technique for treatment. A long term developmental approach is advocated in which the family therapist is the general practitioner rather than the specialist. This paper is the result of a 30-year caseload in which there was a group of multi-therapy families.     

Reconsidering qualitative and quantitative research approaches: A cognitive developmental perspective

Rather than embracing the notion that contextualism requires purely qualitative methodologies, Westerman and Yanchar argue that there is a place for quantification in post-positivist research. Both authors provide compelling arguments for this position. From our cognitive developmental perspective, we see this as a move toward a new level of integration in psychology. Whereas reactive shifts between positivist quantification and radical contextualism exemplify the kind of pendulum swing we see in individual development immediately before the emergence of a new developmental level, the moves suggested by Westerman and Yanchar are in the direction of a qualitative shift—a new level of differentiation and integration. We argue that the arguments put forward by Westerman and Yanchar do not quite achieve consolidation at this new level, because they remain embedded in a post-positivist contextualism that demands an a priori rejection of psychological universals and strong forms of quantification. In our view, consolidation at this new level requires a shift to a problem-focused methodological pluralism that assimilates a wide range of methodological approaches, critiques them, and adapts them in light of the problems researchers seek to solve.     

Play therapy as a family restructuring technique: A case illustration

This paper presents a general treatment approach which uses play to integrate individual and family psychotherapy when working with young children as identified patients. Play therapy techniques are explored with regard to their potential impact upon a family system. Perspectives on concurrent and conjoint family oriented treatment using play are discussed with a focus upon achieving both individual and family system growth.     

Hypnotizability, preference for an imagic cognitive style, and memory creation in hypnosis

We sought to extend the finding (Laurence & Perry, 1983) that it is possible through hypnosis to create a pseudomemory of a specific event. Subjects were compared on their responses to a hypnotic suggestion. We also examined the relation between nonhypnotic measures (Preference for an Imagic Cognitive Style [PICS] test and the Tellegen Absorption Scale [TAS]) and response to the suggestion. Highly (45.45%) and moderately-highly (46.15%) susceptible subjects believed that the pseudomemory was veridical, but none of the low susceptible subjects did so. Together, hypnotic susceptibility, the PICS, and their interaction more strongly predicted pseudomemory creation than any of these main effects alone. Performance on the TAS was also related to the occurrence of pseudomemory, but this relation was redundant with performance on the other measures. These results point to the complexity of the variables involved in pseudomemory creation during hypnosis.     

Spanish developmental dyslexia: Prevalence, cognitive profile, and home literacy experiences

This study was designed to examine the prevalence, cognitive profile, and home literacy experiences in subtypes of Spanish developmental dyslexia. The subtyping procedure used comparison with chronological-age-matched and reading-level controls on reaction times and accuracy responses to high-frequency words and pseudowords. Using regression-based procedures, 8 phonological dyslexics and 16 surface dyslexics were identified from a sample of 35 dyslexic fourth graders by comparing them with chronological-age-matched controls on reaction times to high-frequency word and pseudoword reading. However, when the dyslexic subtypes were defined by reference to reading-level controls, 12 phonological dyslexics were defined but only 5 surface dyslexics were identified. Both dyslexic subtypes showed a deficit in phonological awareness, but children with surface dyslexia also showed a deficit in orthographical processing assessed by a homophone comprehension task. This deficit was associated with poor home literacy experiences, with the group of parents with children matched in reading age, in comparison with the group of parents with children with surface dyslexia, reporting more literacy home experiences.
