Explanations of grouping in immediate ordered recall

This article is about grouping in immediate ordered recall. The following findings are reported: (1) grouping a presentation improves recall, even when steps are taken to prevent rehearsal; (2) grouping primarily improves recall of the items adjoining the grouping, creating primacy and recency within groups; and (3) this primacy and recency are found even when single, isolated errors in recall are considered. These results suggest that the effects of grouping cannot be fully explained by rehearsal, chunking, or the number of directions in which an item can be transposed. It is suggested instead that (1) the auditory short-term store contains an unparsed and uncategorized representation that must be parsed and categorized just prior to recall, in a process of recovery; (2) items adjoining the boundary of a presentation are more easily recovered; and (3) grouping creates a boundary within the presentation. To support this explanation, a final experiment demonstrates an interaction between type of stimuli and serial position, with grouping most improving recall of adjoining phonemes.     

Developmental change in attention-deficit hyperactivity disorder in boys: A four-year longitudinal study

One hundred six clinic-referred boys meeting criteria for DSM-III-R attention-deficit hyperactivity disorder (ADHD) (mean age 9.4 years) were assessed annually for 4 years using structured interviews of multiple informants. Hyperactivity—impulsivity symptoms declined with increasing age, but inattention symptoms did not. Rather, inattention declined only from the first to the second assessment and remained stable thereafter in boys of all ages. The rate of decline in hyperactivity—impulsivity symptoms was independent of the amount and type of treatment received. Boys who still met criteria for ADHD in Years 3 and 4 were significantly younger, more hyperactive—impulsive, and more likely to exhibit conduct disorder in Year 1 than boys who no longer met criteria in Years 3 and 4.This study was supported by grant 1-R01-MH42529 from the National Insitute of Mental Health to Rolf Loeber and Benjamin B. Lahey.     

The Potential Mediating Role of Parenting Practices in the Development of Conduct Problems in a Clinic-Referred Sample

Research has consistently found associations among parenting practices, socioeconomic disadvantage, ethnicity and conduct problems in children. We investigated whether parenting practices might mediate the relation between ethnicity and conduct problems and the relation between socioeconomic status (SES) and conduct problems. The subjects were 141 clinic-referred children between the ages of 6 and 17 and their primary custodial parents. Using multiple indicators for each construct, except ethnicity, the mediational role of parenting was tested using structural equation modeling. The results indicated that the effects of SES on conduct problems was largely mediated by the influence of ineffective parenting practices. In contrast, ethnicity was not associated with conduct problems in this clinic-referred sample, even prior to controlling for SES and parenting practices, suggesting that the link between minority status and conduct problems may be dependent on the demographic characteristics of the sample. Exploratory analyses also revealed that there were ethnic differences in the types of parenting practices that were most strongly associated with conduct problems.     

The level of effort required for behaviour as a moderator of the attitude–behaviour relation

It was hypothesized that the manner in which attitudes influence behaviour is moderated by the level of effort required to perform a behaviour. The effort needed was manipulated in a field experiment by varying the difficulty of getting access to the attitude object. When the behaviour required substantial effort, the mediating role of intentions was strong, and attitudes had only indirect effects on behaviour, consistent with the theory of reasoned action. When the behaviour required little effort, however, attitudes had a significant direct effect on behaviour, and the mediating role of intentions was reduced. The theoretical and practical implications of these findings are discussed.     

Do Self-efficacy Expectation and Spirituality Provide a Buffer Against Stress-Associated Impairment of Health? A Comprehensive Analysis of the German Pastoral Ministry Study

We aimed to analyse stress perception, psychosomatic health and life satisfaction in pastoral professionals, paying particular attention to their individual and shared resources. Enrolling 8574 German pastoral professionals (48 % priests, 22 % parish expert workers, 18 % pastoral assistants, 12 % deacons), we found that pastoral professionals’ stress perception is associated with psychosomatic health impairment. General self-efficacy was a beneficial resource to protect against stress perceptions, while perception of the transcendent had a further yet weakly positive influence for stress-related impairment of health. External stressors (i.e. team size, duration of work per week and size of pastoral unit) were only of marginal independent relevance.     

Der Foto-Hand-Test

Projective psychological techniques might be useful for measuring forensically relevant constructs in the context of a multimodal assessment strategy but are often considered to be deficient concerning reliability and validity. The Photo Hand Test (FHT), a German version of the Hand Test, is a diagnostic tool aimed at measuring aggressive dispositions. It uses photographs of hand gestures which test persons are required to interpret. The answers are coded and an acting-out score is computed from diverse categories.A study on the reliability and validity of the FHT protocols from 98 offenders and a comparison group of 55 non-offenders was carried out. Internal consistency coefficients of the FHT scores were low and unsatisfactory. Offenders had higher acting-out scores than non-offenders, they did not give more aggression-prone interpretations but more interpretations coded as aggression-inhibiting. Correlations of the FHT scores with self-report scales from the Antisocial Personality Questionnaire did not show the expected patterns; however, they did suggest effects of a hostility bias: persons who interpreted many hand gestures as aggression-prone did not describe themselves as highly aggressive or impulsive but were more distrustful and paranoid. This indicates a projection mechanism different from the one postulated by the FHT authors.The results suggest that FHT measures should be interpreted with caution in forensic evaluations.     

„Intention to treat“ oder „treatment as received“ – Umgang mit Abbrechern in der Forschung zur Straftäterbehandlung

Lack of internal validity is a frequent problem in evaluation studies of offender treatment, as randomized controlled trials are difficult to implement and comparison groups in quasi-experimental studies are often not completely equivalent. Special matching procedures or statistical control of selection bias by using potentially interfering variables as covariates can provide a solution to some of these problems; however, a high dropout rate from offender treatment programs presents another problem, as the variables that cause attrition are often risk factors for reoffending. It is argued that a treatment-as-received (TR) approach which compares treatment completers with the comparison group may confound genuine treatment effects with selection effects. Particularly high recidivism rates in dropouts may be due to negative effects of attrition (e.g. stigmatization) but may more likely reflect a higher a priori risk for reoffending. Using data from some recent treatment studies, the authors show that alleged positive effects often disappear when a more adequate intention-to-treat (ITT) approach is used in which dropouts are retained in the treatment sample.
