Affordances and the Nature of Perceptual Content

Abstract

According to John McDowell, representational perceptual content is conceptual through and through. This paper criticizes this view by claiming that there is a certain kind of representational and non‐conceptual perceptual content that is sensitive to bodily skills. After a brief introduction to McDowell’s position, Merleau‐Ponty’s notion of body schema and Gibson’s notion of affordance are presented. It is argued that affordances are constitutive of representational perceptual content, and that at least some affordances, the so‐called ‘conditional affordances’, are essentially related to the body schema. This means that the perceptual content depends upon the nature of the body schema. Since the body schema does not pertain to the domain that our conceptual faculties operate upon, it is argued that this kind of perceptual content cannot be conceptual. At least some of that content is representational, yet it cannot feature as non‐demonstrative conceptual content. It is argued that if it features as demonstrative conceptual content, it has to be captured by private concepts. Since McDowell’s theory does not allow for the existence of a private language, it is concluded that at least some representational perceptual content is non‐conceptual.     

The effectiveness of a proactive coping intervention targeting self-management in diabetes patients

Objective: The study’s aim was to investigate psychological, behavioral and medical long-term outcomes of an existing self-management intervention targeting the development of proactive coping skills (e.g. goal setting and identifying barriers) in type 2 diabetes patients. The study aimed to replicate prior research showing the intervention’s effectiveness, and to extend it by (a) adding booster sessions and (b) prolonging the period of follow-up measurement to capture long-term effects.

Design/outcome measures: A total of 141 type 2 diabetes patients were included in the intervention. The intervention employed a 5-step approach to target proactive coping skills. Psychological (e.g. proactive coping and self-efficacy) and behavioural variables (e.g. self-care, diet and physical activity) were assessed at baseline (T1), after the initial phase of the intervention (T2), after the booster phase (T3) and at follow-up (T4), comprising a total period of 15 months. Medical variables were assessed at T1 and T4.

Results: Employing piecewise Latent Growth Curve Modelling, results showed that participants improved on all psychological and behavioural variables during the initial phase and maintained these improvements over 12 months. The booster phase yielded no further improvements. Mixed findings were obtained on medical outcomes.

Conclusion: The original intervention is effective, but the added value of the booster sessions is uncertain.     

The effect of cognitive load on faking interrogative suggestibility on the Gudjonsson Suggestibility Scale

In the light of recent studies into the impact of cognitive load on detecting deception, the impact of cognitive load on faking on the Gudjonsson Suggestibility Scale (GSS) was investigated. Eighty undergraduate students participated in the study, and were randomly assigned to one of four conditions resulting from a combination of the factors: instruction type (genuine or instructed faking, see Hansen, Smeets, & Jelicic, 2009) and concurrent task (yes or no). Findings show that instructed fakers, not performing a concurrent task, score significantly higher on yield 1 in comparison to genuine interviewees. This is in-line with previous studies into faking on the GSS. However, instructed fakers, performing a concurrent task, achieved significantly lower yield 1 scores than instructed fakers not performing a concurrent task. Genuine (non fakers) showed a different response to increased cognitive load during the dual-task paradigm. This study suggests that increasing cognitive load may potentially indicate (and preclude) faking attempts on the yield dimension of the Gudjonsson Suggestibility Scale.     

Biological motion task performance predicts superior temporal sulcus activity

Numerous studies implicate superior temporal sulcus (STS) in the perception of human movement. More recent theories hold that STS is also involved in the understanding of human movement. However, almost no studies to date have associated STS function with observable variability in action understanding. The present study directly associated STS activity with performance on a challenging task requiring the interpretation of human movement. During functional MRI scanning, fourteen adults were asked to identify the direction (left or right) in which either a point-light walking figure or spinning wheel were moving. The task was made challenging by perturbing the dot trajectories to a level (determined via pretesting) where each participant achieved 72% accuracy. The walking figure condition was associated with increased activity in a constellation of social information processing and biological motion areas, including STS, MT+/V5, right pars opercularis (inferior frontal gyrus), fusiform gyrus, and amygdala. Correctly answered walking figure trials were uniquely associated with increased activity in two right hemisphere STS clusters and right amygdala. Present findings provide some of the strongest evidence to date that STS plays a critical role in the successful interpretation of human movement.     

Supporting children’s counterfactual thinking with alternative modes of responding

To speculate about counterfactual worlds, children need to ignore what they know to be true about the real world. Prior studies yielding individual differences data suggested that counterfactual thinking may be related to overcoming prepotent responses. In two experiments, we manipulated how 3- to 5-year-olds responded to counterfactual conditional and syllogism tasks. In Experiment 1 (N = 39), children’s performance improved on both conditional and syllogism tasks when they responded with an arrow rather than pointing with a finger. In Experiment 2 (N = 42), 3- and 4-year-olds benefited from both an arrow manipulation and, separately, the introduction of a delay before responding. We suggest that both manipulations help children to overcome an impulsive prepotent response to counterfactual questions arising from a default assumption that information about the past is true.     

Deaf and hearing children: a comparison of peripheral vision development

This study investigated peripheral vision (at least 30° eccentric to fixation) development in profoundly deaf children without cochlear implantation, and compared this to age-matched hearing controls as well as to deaf and hearing adult data. Deaf and hearing children between the ages of 5 and 15 years were assessed using a new, specifically paediatric designed method of static perimetry. The deaf group (N = 25) were 14 females and 11 males, mean age 9.92 years (range 5-15 years). The hearing group (N = 64) were 34 females, 30 males, mean age 9.13 years (range 5-15 years). All participants had good visual acuity in both eyes (< 0.200 LogMAR). Accuracy of detection and reaction time to briefly presented LED stimuli of three light intensities, at eccentricities between 30° and 85° were measured while fixation was maintained to a central target. The study found reduced peripheral vision in deaf children between 5 and 10 years of age. Deaf children (aged 5-10 years) showed slower reaction times to all stimuli and reduced ability to detect and accurately report dim stimuli in the far periphery. Deaf children performed equally to hearing children aged 11-12 years. Deaf adolescents aged 13-15 years demonstrated faster reaction times to all peripheral stimuli in comparison to hearing controls. Adolescent results were consistent with deaf and hearing adult performances wherein deaf adults also showed significantly faster reaction times than hearing controls. Peripheral vision performance on this task was found to reach adult-like levels of maturity in deaf and hearing children, both in reaction time and accuracy of detection at the age of 11-12 years.     

Inside the experience of anorexia nervosa: A narrative thematic analysis

Aim: This study considers the question of whether inpatient admission for anorexia nervosa was a therapeutic experience for two women with chronic anorexia nervosa. The question of whether inpatient admission for anorexia nervosa can be therapeutic is not answerable through existing research evidence. Method: The women were interviewed about their experience of having anorexia, its impact on their lives and the treatment they received. The interviews involved learning about the women's experiences by listening to their stories rather than asking them direct questions about what has been therapeutic about their treatment. Analysis: Their narratives were used to develop understanding grounded in experience and were analysed using a narrative thematic analysis. Ideas, themes and connections were noted but not coded as found in some forms of thematic analysis. Discussion: Consideration is given to the therapeutic qualities of the treatments the women received and the place of therapeutic inpatient admission. The central theme of this research was ‘relationships’ which indicates the use of therapeutic approaches that emphasise the importance of the therapeutic relationship in the treatment of chronic anorexia nervosa. It is suggested that psychodynamic and attachment theories should be used to inform overall treatment models. Some important issues for service provision and areas for further research are identified.     

Re-presenting Autism: The Construction of ‘NT Syndrome’

Autism is a widely researched area and much emphasis has been placed in research on the differences between the autistic and non-autistic populations. Such research commonly draws on proposed deficits within people with autism in order to explain differences. This paper seeks to present an alternative understanding of differences and draws on writings of people with autism in such a discussion. The construction of ‘Neurologically Typical syndrome’ (NT) will be presented as an inverted construction of diagnosis, which serves to challenge the dominant position of ‘NTs’ and ‘NT traits’ over autistic traits. It will be argued that such an alternative representation of people with and without autism has important implications for our construction of and understanding of autism.     

A Multifactorial Model for the Etiology of Anxiety in Non-Clinical Adolescents: Main and Interactive Effects of Behavioral Inhibition, Attachment and Parental Rearing

There has been limited research examining the additive and interactive effects of multiple factors on the development of anxiety symptoms and anxiety disorders in youths. This study was an attempt to examine the reciprocal connections among temperament, attachment, and rearing style, and their unique and interactive relations to anxiety symptoms. Six hundred forty-four non-clinical children aged 11–15 years (mean age = 12.7 years) completed questionnaires measuring behavioral inhibition, attachment, parental rearing behavior, and anxiety symptoms. Results indicated that there were small to moderate positive correlations among various risk factors. Furthermore, modest but significant positive correlations were found between behavioral inhibition, attachment quality, and anxious and controlling rearing behaviors on the one hand, and anxiety scores on the other hand. That is, higher levels of behavioral inhibition, insecure attachment, and parental control and anxious rearing were associated with higher levels of anxiety symptoms. Finally, behavioral inhibition, attachment quality, parental control and anxious rearing each accounted for a small but unique proportion of the variance of anxiety disorders symptomatology. Little support was found for interactive effects of these vulnerability factors on childhood anxiety.
