Indexicality,Transparency, and Mental Files

Abstract

Francois Recanati’s Mental Files (Oxford: Oxford University Press, 2012) presents a picture of the mind on which mental representations are indexical and transparent. I dispute this picture: there is no clear case for regarding mental representations as indexical, and there are counterexamples to transparency.     

Non-LIFO Execution of Cognitive Procedures

Many current theories of human problem solving and skill acquisition assume that people work only on the unsatisfied goal that was created most recently. That is, the architecture obeys a last-in-first-out (LIFO) constraint on the selection of goals. This restriction seems necessary for the proper functioning of automatic learning mechanisms, such as production compilation and chunking. It is argued that this restriction is violated by some subjects on some tasks. In particular, 8 subjects (from a sample of 26) execute subtraction procedures in a way that violates the LIFO constraint. Although there is a great deal of between- and within-subject strategy variation in the 8 subjects' behavior, it can be simply explained by hypothesizing that (1) the goal selection is not necessarily LIFO, (2) goal selection knowledge is represented by explicit preferences, and (3) the 8 subjects have just a few preferences that are overgeneralized, overspecialized, or missing. The rest of their preferences are correct. On the other hand, LIFO-based models seem unable to explain the strategy variations in any simple way. Thus, it seems that part of the flexibility in human problem solving comes from having a choice of which goal to work on next. Fortunately, it is simple to ammend automatic learning mechanisms so that they will function correctly in a non-LIFO architecture.     

The facilitatory effect of negative feedback on the emergence of analogical reasoning abilities

This paper focuses on the development of analogical reasoning abilities in 5‐ and 6‐year‐old children. Our particular interest relates to the way in which analogizing is influenced by the provision of task‐based feedback coupled with a self‐explanation requirement. Both feedback and self‐explanation provide children with opportunities to engage in self‐reflective thinking about the process of analogical reasoning. To examine the role of such metacognitive factors in analogical strategy development the reported study combined a proportional analogy paradigm with a small‐scale microgenetic approach involving multiple testing sessions over a restricted time period. The key manipulation involved exposing participants either to the correct or incorrect analogy completions of another reasoner that they were then asked to explain. The data revealed that the development of an effective analogizing strategy embodying a ‘relational shift’ from superficial to relational responding was modulated by the feedback condition that the child was placed in, with a negative feedback intervention providing the greatest developmental benefit. We suggest that the value of negative feedback for the acquisition of analogical reasoning abilities derives from the way in which a self‐reflective analysis of the reasons for erroneous responses sensitizes the child to a deeper understanding of how to make effective relational mappings.     

Body image importance and body dissatisfaction among indigenous Australian adolescents

Despite their elevated risk of health problems and a propensity to be more overweight or underweight relative to the other members of the Australian population, there has been no previous investigation of body image concerns among Indigenous Australians. In this study we investigated the level of body image importance and body image dissatisfaction among 19 rural Indigenous adolescents (7 males, 12 females) and 28 urban Indigenous adolescents (15 males and 13 females). Our hypotheses that there would be gender differences in body image importance and body image satisfaction were not generally supported. However, males placed more importance on muscle size and strength than females, and rural participants placed more importance on weight than urban participants. Comparison to existing data obtained from Caucasian adolescents suggested that Indigenous youth may be less concerned and dissatisfied with body weight and shape. These results are discussed in relation to findings from studies of non-Indigenous adolescents, and Indigenous health issues. The limitations of the current study and the need for further studies are also discussed.     

Relation of useful field of view and other screening tests to on-road driving performance

The purpose of this study was to examine the value of a clinical driving assessment battery in predicting performance on an on-road driving test. 43 participants referred to the Bryn Mawr Rehab Adapted Driving Program for evaluation of driving ability underwent an evaluation consisting of a predriver screening and an on road driving test. The predriver screening included a vision screening, a reaction rime task, a split-attention task, the Hooper Visual Organization Test, verbal and symbolic sign recognition, and assessment of Useful Field of View. Logistic regression analyses were applied to identify which predriver screening variables could be used to predict outcome on the on road driving test (pass/fail); UFOV was that best single predictor. The addition of screening tests beyond UFOV alone did not increase predictive validity. These findings suggest that UFOV may serve as an indicator of the need for further driving assessment.     

Warmth and contingency and their relationship to maternal attitudes toward parenting

In this study, the authors addressed the question of whether maternal parenting behaviors in terms of sensitivity, warmth, and contingency with respect to small infants were equally represented in attitudes toward parenting. Sixty mothers from central Germany with middle-class socioeconomic backgrounds were videotaped with their 1st born 3-month-old infant in a free-play and a caregiving episode in their home. The different maternal parenting components were behaviorally analyzed. Maternal attitudes toward parenting were assessed with self-report measures. The results showed that behavioral sensitivity was significantly associated with attitudes related to contingency, whereas behavioral warmth and contingency were not associated with maternal attitudes. The authors interpreted differential associations as a reflection of intuitive and explicit parenting strategies, with only sensitivity being explicitly represented.     

Addicted patients with personality disorders: traits, schemas, and presenting problems

We evaluated the association of Structure Clinical Interview for the DSM-IV Axis II (SCID-II) severity and personality traits, early maladaptive schemas, and presenting symptoms in 41 methadone-maintained patients meeting criteria for either antisocial, borderline, avoidant, or depressive personality disorder. Correlational analyses indicated that the severity of each personality disorder was associated with a unique profile of presenting problems and underlying traits and schemas. The evaluation of multiple psychological indicators appears to be a useful method for case conceptualization and planning interventions within a promising individual therapy model that focuses both on substance abuse and psychiatric symptoms and maladaptive schemas and coping styles.     

Are Fallacies Vices?

Why are some arguments fallacious? Since argumentation is an intellectual activity that can be performed better or worse, do we evaluate arguments simply in terms of their content, or does it also make sense to evaluate the arguer in light of the content put forward? From a ‘virtue’ approach, I propose understanding fallacies as having some link with intellectual vice(s). Drawing from recent work by Paul Grice, Linda Zagzebski, Andrew Aberdein, and Douglas Walton, this essay argues that if there is some sense of argumentation where an argument is (1) truth-propagating and not (2) put forward in order to ‘win’, fallacies may be the vicious element in arguments that undermines (1), most often because the arguer’s goal is only (2). From this perspective, fallacies may not only be improper ‘moves’ in an argument, but may also reveal something lacking in the arguer’s intellectual character.     

Child‐Witness and Defendant Credibility: Child Evidence Presentation Mode and Judicial Instructions1

Child‐witness presentation mode, judicial instructions, and deliberation stage effects on juror ratings of child witness and defendant were investigated Perceptions of the impact of presentation mode on witnesses, juror task, and justice also were explored. Participants (N= 108) viewed a simulated child sexual abuse trial videotape. Overall child‐witness credibility was significantly more positive with videodeposition or court‐given child evidence than with videolink. The defendant was seen as more definitely guilty when child testimony was court given than by videodeposition or videolink. Presentation mode also significantly influenced perceived impact on child witness, defendant case, and juror task. Judicial instructions interacted with presentation mode to affect perceptions of impact on child witness and juror task. Findings are discussed in relation to previous research, and implications for future research and practice are outlined.
