Representations in dynamical embodied agents: re-analyzing a minimally cognitive model agent

Understanding the role of 'representations' in cognitive science is a fundamental problem facing the emerging framework of embodied, situated, dynamical cognition. To make progress, I follow the approach proposed by an influential representational skeptic, Randall Beer: building artificial agents capable of minimally cognitive behaviors and assessing whether their internal states can be considered to involve representations. Hence, I operationalize the concept of representing as 'standing in,' and I look for representations in embodied agents involved in simple categorization tasks. In a first experiment, no representation can be found, but the relevance of the task is undermined by the fact that agents with no internal states can reach high performance. A simple modification makes the task more "representationally hungry," and in this case, agents' internal states are found to qualify as representations. I conclude by discussing the benefits of reconciling the embodied-dynamical approach with the notion of representation.     

Grandiose Fantasies and Low Self-Esteem: An Experimental Study

Grandiose states of mind could be an ineffective way to cope with low self-esteem. In fact, it is possible that grandiose fantasies would tend to induce doubts about personal worth and decrease self-esteem. This study explored whether grandiose fantasies help to cope with low self-esteem. The self-reported occurrence and unpleasantness of intrusive thoughts regarding the sense of exclusion, humiliation, and low self-esteem in non-clinical individuals were assessed during self-induced grandiose fantasies and self-induced relaxation. The occurrence and unpleasantness of low self-esteem intrusions were significantly higher during grandiose fantasies, suggesting that grandiose fantasy is ineffective at combating low self-esteem.     

Not doing is not the opposite of doing: implications for attitudinal models of behavioral prediction

This study argues for and tests the prediction that cognitions about not performing a behavior are not simple opposites of cognitions about performing the same behavior because they rely on separate goals. Three behaviors (i.e., eating meat, doing vigorous physical activity, and breastfeeding) are examined, for which performing and not performing are means to different goals. In the context of the theory of planned behavior, the discriminant validity of constructs related to performing and not performing behaviors is tested. Moreover, the simultaneous validities of perceived behavioral control over doing and not doing for the prediction of both intentions and the incremental validity of both intentions in predicting behavior are investigated. Results show that the constructs related to performing and not performing a behavior independently contribute to the prediction of intentions and behaviors. Implications of considering separable motivational systems underlying doing and not doing are discussed.     

At the core of cyberaggression: A group-based explanation

In this study, prototypicality of the aggressor was tested as a group-level factor predicting social media users’ active participation in cyberaggression. Participants were exposed to a fictitious conversation, in which either a prototypical versus non-prototypical user posted an aggressive comment as a reply to a provocative comment. In line with self-categorization theory, we hypothesized that bystander participants would post an aggressive comment and rate the aggression as acceptable to a greater extent in the prototypical than in the non-prototypical condition. Furthermore, we predicted that perceived normativity of aggression would mediate the effect of prototypicality. Results supported these predictions and showed that prototypical members affect the extent to which collective aggressive behaviors in online interactions are approved and enacted. These findings highlight the importance of group-level factors in the study of cyberaggression and provide important information for understanding the psychological underpinnings of collective forms of online aggression.

A Twin Study of the Relationships among Inattention, Hyperactivity/Impulsivity and Sluggish Cognitive Tempo Problems

We investigated the etiological relationships between the three ADHD dimensions of Inattentive Problems (INP), Hyperactivity-Impulsivity Problems (HIP) and Sluggish Cognitive Tempo (SCT) as measured by the CBCL 6–18 questionnaire. Multivariate models were applied to 398 twin pairs (374 boys and 422 girls) aged 8 to 17 years (M?=?13.06, SD?=?2.59) belonging to the population-based Italian Twin Registry. The INP, HIP and SCT problem scores were moderately-to-substantially (range 0.29–0.47) intercorrelated. The best fitting model showed that these 3 dimensions are correlated both at the genetic (correlations’ range: 0.65–0.83) and the environmental (correlations: 0.29 and 0.44) levels, but they are also distinct. While SCT showed moderate heritability and large non-shared environmental influences, variance for both INP and HIP was substantially explained by genetic influences. We also found evidence of negative sibling interaction for INP, implying that a given behavior in one twin leads to an opposite behavior in the co-twin. Our results support at the etiological level the findings of previous psychometric and longitudinal studies of ADHD, which yielded evidence of the 3 distinct—albeit correlated—problem dimensions of inattentiveness, hyperactivity-impulsivity, and sluggish cognitive tempo.     

Factor structure and behavioural correlates of the Psychopathy Checklist-Revised [PCL-R] in a Brazilian prisoner sample

The present study examines the reliability, factor structure, and criterion-related validity of Hare (2003) Revised Psychopathy Checklist [PCL-R] in a Latin American forensic context. Brazilian male inmates (124) were administered the PCL-R, along with relevant subscales of an inventory of normal personality [Personality Factorial Inventory], an intelligence scale [Standard Progressive Matrices], and a semi-structured interview based in DSM IV. Criminal offence records were obtained from prison files. Several theoretical factorial structures for the PCL-R were tested and compared. A bifactor model with three factors, one general factor reflecting the overlap across all items, and two independent subfactors reflecting the unique covariation among particular groups of items, shows the better fit. Overall scores on the PCL-R correlated with the number of criminal offenses committed by participants. No significant correlations were found between PCL-R scores and personality or intelligence measures. It was concluded that the PCL-R is a reliable and valid instrument for the assessment of psychopathy in the Brazilian male forensic population.     

Recovering Identity from Anorexia Nervosa: Women's Constructions of Their Experiences of Recovery from Anorexia Nervosa Over 10 Years

There is little consensus about the meaning of recovery in anorexia nervosa with most studies focusing on researcher selected variables of weight gain and improvement in eating disorder symptomatology. There is also a paucity of research that focuses on how the experiencing person themselves define recovery and whether this term is useful to them to depict their journey of reclaiming their life and identity from anorexia nervosa. This article explores 21 Australian women's experiences of anorexia nervosa (AN) over 10 years and the ways they negotiated their identities in relation to the question of recovery. The research interviews sought to provide a context for these women to speak on their own terms, terms not confined to the medical discourse. The discursively constructed category of recovery was troublesome for the majority of these women, despite the researcher inadvertently taking up this category in lines of questioning, particularly in the earlier interviews. Most troubling for the women was the assumption that recovery erased their experiences with the expectation that they should return to a pre-illness state. On the other hand, speaking on their own terms—including the use of metaphor and (re)authoring their experiences as an identity journey—was significant in scaffolding the women toward narratives of reclaiming their lives and identities from AN and its effects. The women in this study refused to confine the terms of their speaking to a recovery discourse; instead, they honored the narratives of their experiences and histories as profound in their identity formation. The implications of this research are significant given that the majority of research and many treatments to date confine the terms of speaking to the “anorexia” discourse.
