Developmental Trends in False Memory Across Adolescence and Young Adulthood: A Comparison of DRM and Memory Conformity Paradigms

Little is known about the reliability of eyewitness memory among adolescents as most memory research has focused primarily on adults and young children. A number of studies recently have emerged outlining conditions where memory suggestibility increases from early childhood to adulthood. These developmental reversals are found in semantic association tasks such as the Deese–Roediger–McDermott (DRM) paradigm and have not yet been thoroughly investigated among adolescents. In the current study, we examined DRM performance among 11–21 year olds (N = 245). Extending the work comparing children and adults, false memory on the DRM task increased with age. False memory on the DRM task was not associated with false memory on a memory conformity task. The different memory processes involved with the tasks and the implications for legal psychology are discussed. Copyright © 2015 John Wiley & Sons, Ltd.     

Impulsive for life? The nature of long-term impulsivity in domestic dogs

Individual differences in impulsivity occur at a cognitive and/or behavioural level and are associated with differing life outcomes. However, there is a lack of empirical evidence to support the long-term stability of these characteristics in non-human animals. This study reports on the stability of convergent measures of impulsivity in domestic dogs assessed more than 6 years apart. Measures were (1) owner assessment by means of a questionnaire, the validated ‘Dog Impulsivity Assessment Scale’ (DIAS) and (2) dogs’ performance in a delayed reward choice test. Dogs had 15-min free access to two food dispensers, one dispensing a piece of food immediately, the other dispensing three pieces after a delay, which increased by 1 s every other time the dogs sampled it. Maximum delay reached in this task reflects decision-making, or cognitive impulsivity, whereas the rate of extra presses on the delayed reward device during the delay can be considered as a measure of motor or behavioural impulsivity. DIAS scores were strongly and significantly correlated across years. The maximum delay reached in the behaviour test was also highly stable, whereas paw-pressing rate was uncorrelated between the years. These results demonstrate that cognitive but not motor impulsivity is highly consistent over time in dogs.     

A teacher‐centered exploration of the relevance of social factors to theory of mind development

Many accounts of children's Theory of Mind (ToM) development favor a cognitive explanation, for example, in terms of mental representational improvements at or before 4 years. Here, we investigated whether social factors as rated by a child's teacher, are related to ToM development. We tested 82 children of 3–6 years on each of four ToM tasks, and their class teacher completed a social questionnaire about each child's playing behavior, sharing, talkativeness, confidence, aggressiveness and outgoingness. A measure of task memory and the child's gender were also recorded. Here, children generally passed ToM tasks after 5 years‐old, but no one gender performed reliably better than the other. Teacher‐rated confidence and playing behavior were correlated to ToM. But in a regression analysis, these were replaced by teacher‐rated talkativeness; with age and memory given primacy in both sets of analyses. It is concluded that maturation and cognitive factors may well have primacy but social factors, facilitated during early primary education, must also be given a role in ToM development.     

Consumer culture ideals,extrinsic motivations,and well‐being in children

Internalising the consumer culture ideals of materialism and appearance has been shown to be negatively related to adults' well‐being. Similarly, adults who strive towards these ideals for extrinsic reasons, such as to improve their image or status, have been shown to have lower levels of well‐being than those who strive towards them for intrinsic reasons, such as to help others or support healthy relationships. However, to date, there is little evidence that these links exist in children. In the present research, we use new, age‐appropriate scales to test our predictions derived from self‐determination theory that being extrinsically motivated to achieve materialistic and appearance ideals will predict their internalisation, which, in turn, will negatively predict children's well‐being. An initial pilot study found that extrinsic motives were negatively related to well‐being in a sample of 150 children aged 8–11 years but that intrinsic motives were not. In our main study, we modelled materialism and appearance as indicators of a single underlying consumer culture construct, and, in a sample of 160 youths aged 8–15 years, found support for our hypothesis that being extrinsically motivated to achieve these consumer culture ideals predicts their internalisation, which negatively predicts well‐being. We discuss the possible mechanisms involved in these processes and the implications of these findings for future research. Copyright © 2014 John Wiley & Sons, Ltd.     

Caution or Warning? A Validity Study of the MAYSI‐2 with Juvenile Offenders

Given the high prevalence of mental health and substance use disorders in the juvenile justice system and the emphasis on efficient screening and referrals, the current study sought to further validate the use of the Massachusetts Youth Screening Instrument version 2 (MAYSI‐2). Using data from institutionalized delinquents (N = 836) committed to the California Youth Authority, finite mixture modeling was employed to identify distinct latent classes based on MAYSI‐2 scale scores. Identified classes were then compared across a range of covariates, including prior offenses, official records of misconduct, and multiple measures of mental health and psychological well‐being. Findings revealed a three‐class, gradient‐based structure: low distress (n = 380), moderate distress (n = 327), and high distress (n = 129). Overall, the MAYSI‐2 identified juvenile offenders with mental health and substance use issues, but it did not differentiate youths with respect to offending patterns.

The Influence of Clinical Experience and Assessment Method on the Evaluation of Child Behavior Change

This research examined how people’s ability to detect behavior change in simulated child targets is affected by their clinical experience and the assessment method they use. When using summary assessment methods that are widely employed in research and clinical practice, both inexperienced and experienced clinical staff detected changes in the overall frequency of targets’ aggressive behavior, but were not uniquely influenced by changes in targets’ reactions to social events. When using contextualized assessment methods that focused on conditional reactions, experienced staff showed greater sensitivity than novices to context-specific changes in targets’ aggressive and prosocial reactions to aversive events. Experienced staff also showed greater sensitivity to context-specific changes in their overall impressions of change, but only for aggression. The findings show how clinically experienced judges become more attuned to if…then… contingencies in children’s social behavior, and how summary assessment methods may hamper the detection of change processes.     

Conceptual and Statistical Interactions: An Illustration with the AB5C and CWBs

Purpose

The purpose of this study was to compare the criterion validity of conceptual interactions between the Big Five traits of agreeableness, conscientiousness, and emotional stability to the statistical interactions between these traits. For illustration purposes we focus on linking these interactions to counterproductive work behaviors (CWBs).

Design/Methodology/Approach

Data for Study 1 was obtained from 196 employed students and focuses on the interaction between agreeableness and conscientiousness. Data for Study 2 was obtained from 220 employees and expanded the interaction space examined to include emotional stability.

Findings

All of the circumplex traits representing conceptual interactions were related to CWBs but only the traits most closely associated with conscientiousness showed incremental validity beyond their associated Big Five traits. Dominance analysis highlights increased concurrent validity of the circumplex traits compared to the Big Five statistical interactions in relation to CWBs.

Implications

Understanding the unique circumplex blends of the Big Five traits offers opportunities to enhance the criterion validity of Big Five measures. Results question the similarity between the AB5C circumplex traits and Big Five interactions, with their contributions appearing to be unique but their justification drastically different.

Originality/Value

The validity of the AB5C circumplex traits are relatively unknown. The current results expand this knowledge and directly compare the circumplex traits to interaction terms between agreeableness, conscientiousness, and emotional stability.
