The Effects of Incentives on Visual–Spatial Working Memory in Children with Attention-deficit/Hyperactivity Disorder

Working memory is one of several putative core neurocognitive processes in attention-deficit/hyperactivity disorder (ADHD). The present work seeks to determine whether visual–spatial working memory is sensitive to motivational incentives, a laboratory analogue of behavioral treatment. Participants were 21 children (ages 7–10) with a diagnosis of ADHD-combined type. Participants completed a computerized spatial span task designed to assess storage of visual–spatial information (forward span) and manipulation of the stored information (backward span). The spatial span task was completed twice on the same day, once with a performance-based incentive (trial-wise feedback and points redeemable for prizes) and once without incentives. Participants performed significantly better on the backward span when rewarded for correct responses, compared to the no incentive condition. However, incentives had no effect on performance during the forward span. These findings may suggest the use of motivational incentives improved manipulation, but not storage, of visual–spatial information among children with ADHD. Possible explanations for the differential incentive effects are discussed, including the possibility that incentives prevented a vigilance decrement as task difficulty and time on task increased.     

“Not a little Mickey Mouse thing”: How experienced counselling psychologists describe the significance of personal therapy in clinical practice and training. Some results from an interpretative phenomenological analysis

The British Psychological Society's Division of Counselling Psychology currently specifies a mandatory period of personal therapy for trainees. However, evidence for the role of personal therapy in developing practitioner competence is sparse. This paper presents part of a wider ongoing interpretative phenomenological analysis exploring how counselling psychologists describe the meaning and significance of personal therapy in clinical practice and training. Detailed examination of a subset of data from this study suggests that personal therapy is valued as a vehicle for a genuine, often extremely intense relationship with the therapist, through which participants become able to establish authentic emotional contact with themselves and their clients. Whilst most participants felt that personal therapy should remain an obligatory part of the training curriculum, they were ambivalent about specifying its aims or evaluating its outcomes. Results are discussed in terms of the importance of establishing a sense of integrity and authenticity within the personal therapy experience and are tentatively situated within a possible theoretical framework drawing on current developmental literature.     

Classroom observations of students with and without ADHD: Differences across types of engagement

The current study examined the behaviors related to academic engagement exhibited by students with ADHD during instruction in math and reading. A total of 155 students (92 ADHD, 63 recruited controls) in grades 1 through 4 participated in the study. Results revealed that students with ADHD exhibited statistically significant lower rates of academic engagement and higher rates of off-task behaviors than recruited controls and randomly selected peer comparisons. Specifically, students with ADHD exhibited statistically significant lower rates of passive academic engagement (PET) than recruited controls and peer comparisons; however no group differences were found with regard to active engaged time (AET). In addition, students with ADHD exhibited lower rates of AET than PET, a finding observed among both recruited controls and randomly selected peer comparisons. Implications for research and practice are discussed.     

Validation of the Japanese Version of the Modified Balanced Time Perspective Scale: Factor Structure,Reliability, and Validity Results1

A balanced time perspective (BTP) is defined as a frequent and equal tendency to think positively about both one's past and future. A BTP is related to greater psychological well-being, such as life satisfaction and wisdom, and these BTP associations may vary cross-culturally, although few studies of BTP in non-Western countries exist. In order to advance cross-cultural comparisons of BTP, an important methodological step is to validate BTP measures in different cultures. This study aimed to develop and validate a Japanese version of the modified Balanced Time Perspective Scale (mBTPS). Japanese participants (N = 1,020, aged 18–79 years) completed the mBTPS-J, along with Japanese versions of the Zimbardo Time Perspective Inventory (ZTPI-J) and measures of well-being (life satisfaction and wisdom scales). Factor analysis of the mBTPS-J resulted in a 27-item mBTPS-J consisting of Past, Present, and Future subscales. Correlations between the relevant mBTPS-J and ZTPI-J subscales, and with the well-being measures, supported both convergent and predictive validity, respectively. The demonstrated psychometric strengths of the mBTPS-J will allow for specific testing of important cross-cultural questions.     

The role of self-blame for trauma as assessed by the Posttraumatic Cognitions Inventory (PTCI): a self-protective cognition?

The Posttraumatic Cognitions Inventory (PTCI) assesses cognitions hypothesised to be associated with poor recovery from traumatic experiences and the maintenance of PTSD. The validity of the PTCI has received good support but doubts have been raised about its Self-BLAME subscale. The main aim of the present study was to test the ability of the PTCI subscales to discriminate between traumatised individuals with and without PTSD and to predict posttraumatic symptom severity. Participants (N=63) who had experienced a traumatic event were recruited via the media and completed the PTCI and self-report measures of PTSD and depression symptoms. Full criteria for a diagnosis of PTSD were met by 37 but not by the other 26. There were significant differences between these two groups on the total PTCI score and the Negative Cognitions About SELF and the Negative Cognitions About the WORLD subscales, but not on the Self-BLAME subscale. The two groups were discriminated by the PTCI subscales with 65% accuracy and the multiple correlation (R=.68) between the subscales and posttraumatic symptom severity was highly significant. However, in these analyses, higher scores on the Self-BLAME subscale were associated with less risk of a diagnosis of PTSD and with less posttraumatic symptomatology. Possible interpretations of these results, in terms of statistical suppressor effects and the protective role of behavioural self-blame, are discussed.     

Parenting Cognitions Associated with the Use of Psychological Control

Psychological control is a pattern of parenting that is intrusive and manipulative of children's thoughts, feelings, and attachment to parents. Although little is known about the determinants of psychological control, it has been linked to the psychological status of the parent. We hypothesized that several parenting cognitions reflecting personal concerns would be associated with the use of psychological control: low perceived control, sensitivity to hurt, and a disapproving attitude to negative emotion. We also examined moderating associations with child temperament and child gender. Participants were 198 mothers and fathers of 3- and 4-year-olds (106 boys, 92 girls; M age = 4.10 years, SD = 0.26). Parents completed self- and spouse-report measures of psychological control, rated their child's temperamental characteristics, and completed measures of parenting cognitions. Predictions were generally supported for two of the three cognitions. Sensitivity to hurt and disapproval of negative emotion were associated with more frequent reported use of psychological control. There were some moderating effects of child characteristics.     

Diversion of attention in everyday concept learning: Identification in the service of use

Many people tend to believe that natural categories have perfectly predictive defining features. They do not easily accept the family resemblance view that the features characteristic of a category are not individually sufficient to predict the category. However, common category-learning tasks do not produce this simpler-than-it-is belief. If there is no simple classification principle in a task, the participants know that fact and can report it. We argue that most category-learning tasks in which family resemblance categories are used fail to produce the everyday simpler-than-it-is belief because they encourage analysis of identification criteria during training. To simulate the learning occurring in many natural circumstances, we developed a procedure in which participants' analytic activity is diverted from the way in which the stimuli are identified to the use to which the stimuli will be put. Finally, we discuss the prevalence of this diverted analysis in everyday categorization.     

Iffy beliefs: Conditional thinking and belief change

The ability to entertain possibilities and draw inferences about them is essential to human intelligence. We examine the hypothesis that conditional if-then statements trigger a mental simulation process in which people suppose the antecedent (if statement) to be true and evaluate the consequent (then statement) in that context. On the assumption that supposing an event to be true increases belief that the event has occurred or will occur, this hypothesis is consistent with the claim that evaluating a conditional will heighten belief in its antecedent more than in its consequent. Two experiments, employing conditionals of the form If animal A has property X, then animal B will have property X, in which X was a property that people could not readily relate to the animals, supported this claim. The effect was stronger following the evaluation of conditionals with dissimilar animal categories.
