The Lawyer in the Dutch Interrogation Room: Influence on Police and Suspect

In many European countries, providing a suspect in custody with legal aid before the first police interrogation is a heavily debated issue. In this paper, we report on an exploratory study on the use of coercion by the police and the use of the right to silence by suspects in 70 Dutch homicide cases and their relation to prior consultation and presence of a lawyer. Analysis of the data indicates that there is a relation between the presence of a lawyer in the interrogation room and the way in which police interrogators use coercion. To gain insight into whether the police use coercion and how this is achieved, we looked at the extent to which the interrogators make use of certain interrogation techniques and how the interrogation techniques are used to exert coercion. We found that legal advice from a lawyer before and during the interrogation corresponds with suspects more often using their right to silence. It also appears that the police are inclined to use ‘hard coercion’ when confronted with a silent suspect. The research thus raises the question as to whether the presence of a lawyer is an adequate way to prevent false confessions. Copyright © 2012 John Wiley & Sons, Ltd.     

Learning of timing patterns and the development of temporal expectations

The present study investigated the learning of a culturally unfamiliar musical rhythm, leading to the development of temporal expectations, and it explored the potential for generalization across tempi and tasks. With that aim, we adapted the serial reaction time task to examine the learning of temporal structures by an indirect method. The temporal pattern employed was based on a complex interval ratio (2:3) and compared to one based on a simple interval ratio (1:2). In the exposure phase, non-musician participants performed a two-choice speeded discrimination task that required responding by key press to each event of the simple or complex auditory pattern. Participants were not informed about the temporal regularities; their task solely concerned the discrimination task. During exposure (Experiments 1–3), response times decreased over time for both temporal patterns, but particularly for the events following the longer interval of the more complex 2:3 pattern. Exposure further influenced performance in subsequent testing phases, notably the precision of tap timing in a production task (Experiment 2) and temporal expectations in a perception task (Experiment 3). Our findings promote the new paradigm introduced here as a method to investigate the learning of temporal structures.     

Play it again: did this melody occur more frequently or was it heard more recently? The role of stimulus familiarity in episodic recognition of music

Episodic recognition of novel and familiar melodies was examined by asking participants to make judgments about the recency and frequency of presentation of melodies over the course of two days of testing. For novel melodies, recency judgments were poor and participants often confused the number of presentations of a melody with its day of presentation; melodies heard frequently were judged as have been heard more recently than they actually were. For familiar melodies, recency judgments were much more accurate and the number of presentations of a melody helped rather than hindered performance. Frequency judgments were generally more accurate than recency judgments and did not demonstrate the same interaction with musical familiarity. Overall, these findings suggest that (1) episodic recognition of novel melodies is based more on a generalized "feeling of familiarity" than on a specific episodic memory, (2) frequency information contributes more strongly to this generalized memory than recency information, and (3) the formation of an episodic memory for a melody depends either on the overall familiarity of the stimulus or the availability of a verbal label.     

Assessing normative approaches to communicating violence risk: a national survey of psychologists

There is growing attention to the importance of violence risk communication, and emerging empirical evidence of how evaluating clinicians who conduct risk assessments communicate their conclusions about the risk of violence toward others. The present study addressed the perceived value of different forms of risk communication through a national survey of practicing psychologists (N = 1,000). Responses were received from a total of 256 participants, who responded to eight vignettes in which three factors relevant to risk communication were systematically varied in a 2 x 2 x 2 within-subjects design, counterbalanced for order: (i) risk model (prediction oriented versus management oriented), (ii) risk level (high risk versus low risk), and (iii) risk factors (static versus dynamic). Participants were asked to rate the value of six styles of risk communication for each of eight vignettes. The most highly valued style of risk communication involved identifying risk factors applicable to the individual, and specifying interventions to reduce risk. These results were consistent with findings from several previous studies in this area, and reflect an emerging trend in preferences for style and context of risk communication of violence.     

Smoking withdrawal dynamics: I. Abstinence distress in lapsers and abstainers

Smoking withdrawal reports from a clinical trial (n = 893) were submitted to hierarchical linear modeling as a cross-method replication of a heterogeneity approach to withdrawal measurement and to clarify the influence of postcessation smoking on symptom reports. Five individual difference parameters tapping distinct facets of withdrawal were derived: intercepts (mean severity), linear slope (direction and rate of change), quadratic trend (curvature), volatility (scatter) and, among lapsers, a cigarette coefficent (smoking-related deflections of symptoms). All parameters were highly variable across persons. Lapsers had more aversive symptom patterns than abstainers, and symptoms tended to be higherthan otherwise predicted on lapse days. These results reinforce the conclusion that withdrawal symptoms are highly variable and argue against discarding withdrawal data from participants who lapse.     

Infants show a facilitation effect for native language phonetic perception between 6 and 12 months

Patterns of developmental change in phonetic perception are critical to theory development. Many previous studies document a decline in nonnative phonetic perception between 6 and 12 months of age. However, much less experimental attention has been paid to developmental change in native-language phonetic perception over the same time period. We hypothesized that language experience in the first year facilitates native-language phonetic performance between 6 and 12 months of age. We tested 6-8- and 10-12-month-old infants in the United States and Japan to examine native and nonnative patterns of developmental change using the American English /r-l/ contrast. The goals of the experiment were to: (a) determine whether facilitation characterizes native-language phonetic change between 6 and 12 months of age, (b) examine the decline previously observed for nonnative contrasts and (c) test directional asymmetries for consonants. The results show a significant increase in performance for the native-language contrast in the first year, a decline in nonnative perception over the same time period, and indicate directional asymmetries that are constant across age and culture. We argue that neural commitment to native-language phonetic properties explains the pattern of developmental change in the first year.     

Interference effects demonstrate distinct roles for visual and motor imagery during the mental representation of human action

Four experiments were completed to characterize the utilization of visual imagery and motor imagery during the mental representation of human action. In Experiment 1, movement time functions for a motor imagery human locomotion task conformed to a speed-accuracy trade-off similar to Fitts' Law, whereas those for a visual imagery object motion task did not. However, modality-specific interference effects in Experiment 2 demonstrate visual and motor imagery as cooperative processes when the action represented is tied to visual coordinates in space. Biomechanic-specific motor interference effects found in Experiment 3 suggest one basis for separation of processing channels within motor imagery. Finally, in Experiment 4 representations of motor actions were found to be generated using only visual imagery under certain circumstances: namely, when the imaginer represented the motor action of another individual while placed at an opposing viewpoint. These results suggest that the modality of representation recruited to generate images of human action is dependent on the dynamic relationship between the individual, movement, and environment.     

Efficacy of In-Home Parent-Child Interaction Therapy

ABSTRACT

In recent years, there has been much discussion of the efficacy of mental health interventions for children as well as the transportation of empirically-supported treatments (ESTs) to field settings. A logical initial step in this line of research is to examine whether the efficacy of ESTs can be demonstrated in community settings such as in the home environment. The purpose of the study was to examine the efficacy of an in-home Parent-Child Interaction Therapy (PCIT) program using a single-subject, A/B design across five subjects with staggered baselines. Decreases in caregiver use of negative behavior and caregiver-reported child behavior problems were observed for the three families that completed treatment. In addition, completers demonstrated increases in child compliance, caregiver use of positive behavior, and contingent praise. Data regarding caregivers' reported parenting stress and caregiver proportion of direct commands were less convincing. All three dyads completing treatment reported satisfaction with the intervention. Clinical implications regarding the possible benefits of PCIT for improving the effectiveness of home visiting programs are discussed as well as directions for future research.     

Individual differences in opportunistic claiming behavior

This study examines the role of individual difference variables in opportunistic claiming after service failure. Drawing on research in the conflict literature, social value orientation (SVO) and conflict style are investigated as possible influences. The results suggest that both SVO and conflict style impact the amount claimed and opportunistic behavior. This research provides additional insight into why claiming behavior varies even when consumers have the same experience. Copyright © 2013 John Wiley & Sons, Ltd.
