A Mixed Methods Study of the Re-Animation Approach Within a Forensic Mental Health Setting

This mixed-methods study investigated the impact of the Re-Animation Approach, a creative occupational therapy, on the well-being and occupational performance of three male patients in a forensic mental health setting. Quantitative data were gathered through goal attainment scaling (GAS) and qualitative data using semi-structured interviews. GAS t-scores demonstrated an over-achievement of expected outcomes in goals related to improving skills, well-being, and time use. Issues emerging from thematic analysis of the interviews are consistent with the GAS results. The Re-Animation Approach had a positive impact on participants’ health and well-being, addressed a range of occupational needs, and can be graded.     

Diferencias individuales en cognición: una nueva aproximación a la inteligencia

RESUMEN

El hecho de las diferencias individuales en el funcionamiento mental es una realidad. Su amplitud y naturaleza tiene unas consecuencias tan importantes en nuestra cultura que hace que la sociedad demande una forma de medir la inteligencia. No obstante algunos psicólogos opinan que los tests de inteligencia son un instrumento de medida que no representa adecuadamente un modelo formal de la dinámica de los procesos de pensamiento. Este artículo consiste en una serie de argumentos teóricos y empíricos contra la separación de los tests y las teorías cognitivas. Se piensa, en este artículo, que se pueden producir substanciales beneficios del acercamiento entre el psicólogo experimental y el psicómetra; los datos disponibles indican cómo se puede producir este acercamiento.     

A history of my animus dreaming,waking

In a recent episode of the TV series Star Trek: The Next Generation, Captain Jean-Luc Picard and the crew of the starship Enterprise land surreptitiously on a distant planet. When they are discovered by the humanoid inhabitants, who have webbed feet and toes and a raised ridge on their foreheads, the human invaders explain that their mission is to assist planetary cultures like theirs when they are ready to begin space travel.     

Spearman's law of diminishing returns: A statistical artifact?

Spearman's Law of Diminishing Returns (SLODR) is the idea that the structure of human cognitive ability is more differentiated and g a weaker determinant of cognitive performance at higher levels of ability. In this study, we distinguish between ‘traditional’ methods of testing SLODR and ‘contemporary’ methods of testing SLODR. It is the former set of methods from which the vast majority of the evidence base for SLODR derives. We demonstrated that it is easy to mimic SLODR and reverse SLODR effects in these traditional methods of assessing SLODR by using data with skewed observed variable distributions. The skewness magnitudes did not need to be large to produce these effects and they fell well within the range of values that are usually considered unproblematic for parametric statistic analysis. In simulated datasets, positive subtest skewness resulted in SLODR and negative subtest skewness resulted in reverse SLODR. In contemporary methods of testing SLODR, non-linear g-loadings or a skewed g are assumed to reflect evidence for SLODR. When we applied contemporary methods of testing SLODR to these data, there was evidence of heteroscedastic residuals but no evidence of non-linear g-loadings or skewed g distributions. We broadly replicated the effects of subtest skew from these simulated datasets in real data from the Minnesota Study of Twins Reared Apart. Results imply that traditional methods of assessing SLODR cannot distinguish between effects due to subtest characteristics that have nothing to do with differences in ability structure at different levels of g and true SLODR effects. This calls into question the empirical support for SLODR.     

Reduced Reliance on Optimal Facial Information for Identity Recognition in Autism Spectrum Disorder

Previous research into face processing in autism spectrum disorder (ASD) has revealed atypical biases toward particular facial information during identity recognition. Specifically, a focus on features (or high spatial frequencies [HSFs]) has been reported for both face and nonface processing in ASD. The current study investigated the development of spatial frequency biases in face recognition in children and adolescents with and without ASD, using nonverbal mental age to assess changes in biases over developmental time. Using this measure, the control group showed a gradual specialization over time toward middle spatial frequencies (MSFs), which are thought to provide the optimal information for face recognition in adults. By contrast, individuals with ASD did not show a bias to one spatial frequency band at any stage of development. These data suggest that the “midband bias” emerges through increasing face-specific experience and that atypical face recognition performance may be related to reduced specialization toward optimal spatial frequencies in ASD.     

Modifying driver behaviour with passenger feedback

A feedback programme was employed to help drivers improve their safety behaviour based on the idea that particular types of driver error result from contingency traps as defined by Fuller [Journal of Applied Behaviour Analysis, 24 (1991) 73]. Two drivers and their single respective passengers participated. For each driver, repeated in-car observations were made of four unsafe driving behaviours. Two of these were sequentially targeted in the behavioural intervention that involved the passengers providing informational feedback to their driver. Both drivers showed a marked improvement across the targeted behaviours. The study demonstrated the applicability of behaviour analysis to the traffic domain and the efficacy of individual feedback as a behavioural tool for positive behaviour modification.     

Moral reasoning,emotion understanding,and callous-unemotional traits in early-to-middle childhood

Relatively little is known about features of moral reasoning among young children with callous-unemotional (CU) traits (e.g., lack of guilt and empathy). This study tested associations between CU traits and emotion attributions (i.e., identification of others’ emotional states) and justifications (i.e., explanations for those emotional states), across social scenarios involving discreet versus salient distress cues. The participants were boys aged 6-to-10 years (N = 50; M_age = 7 years 7 months), who were interviewed about 12 hypothetical scenarios (eight with discreet and four with salient distress cues). Regression models indicated that CU traits, in interaction with high levels of antisocial behaviour, were associated with reduced emotion attributions of fear in discreet but not salient immoral scenarios. Higher CU traits were also associated with reduced justifications referencing others’ welfare in discreet scenarios, and increased references to action-orientated justifications in salient scenarios. These findings suggest that CU traits are associated with early moral reasoning impairments and that salience of distress may be important to these processes.     

Presentation modality affects false memory

Roediger and McDermott (1995) rejuvenated interest in Deese’s (1959) paradigm for producing reliable intrusions and false alarms. Using this paradigm in three experiments, we demonstrated that visual study presentation dramatically reduces the rate of false memories. Only auditory study presentation resulted in equal production of studied and critical items. Correct recall and recognition were unaffected. The suggestion that visual presentation provides a means for discriminating between false and true memories was supported by Experiment 3: Pleasantness rating of study items significantly reduced the creation of false memories regardless of modality.
