Are affordances normative?

Phenomenology and the Cognitive Sciences - In this paper we explore in what sense we can claim that affordances, the objects of perception for ecological psychology, are related to normativity....     

Can object affordances impact on human social learning of tool use?

The author describes "higher" and "uniquely human" sociocognitive skills that he argues as being necessary for tool use. We propose that those skills could be based on simpler detection systems humans could share with other animal tool users. More specifically, we discuss the impact of object affordances on the understanding and the social learning of tool use.     

Informational affordances: evidence of acquired perception–action sequences for information extraction

Visual objects can automatically prime actions allowing efficient interaction with them. The present study examined whether object perception can automatically prime actions leading to efficient information extraction. Participants in Experiment 1 learned to rotate a cube in a specific way with the end goal of efficiently revealing object-identifying information. In Experiments 2 and 3, the end goal of obtaining object-identifying information was removed, but the stimulus-response associations were preserved. Only object views associated with actions learned in the context of obtaining identifying information caused response interference and benefits in a subsequent test phase where the object was irrelevant. These results demonstrate the existence of informational affordances: perception-action sequences acquired with the goal of information extraction that are automatically primed during later exposure to the object. Perceptual priming of actions for efficient information extraction is an important component of expert performance and its use of action systems to optimally deal with the world.     

Are different affordances subserved by different neural pathways?

This paper questions whether affordances are allied exclusively to dorsal stream processing within the visual system, or whether in fact different affordances are subserved by functionally independent neural pathways. Using case study evidence from patients with various visual pathologies, I argue that affordances can be categorised into type based upon their respective neurological underpinning. Such categorisation has implications for the extent to which affordances are consciously perceived or non-consciously 'picked up' within the optic array, as well as whether they indicate merely potentials for action or provide necessary information in the actualisation of behaviour.     

A frog in your throat or in your ear? Searching for the causes of poor singing

Singing is a cultural universal and an important part of modern society, yet many people fail to sing in tune. Many possible causes have been posited to explain poor singing abilities; foremost among these are poor perceptual ability, poor motor control, and sensorimotor mapping errors. To help discriminate between these causes of poor singing, we conducted 5 experiments testing musicians and nonmusicians in pitch matching and judgment tasks. Experiment 1 introduces a new instrument called a slider, on which participants can match pitches without using their voice. Pitch matching on the slider can be directly compared with vocal pitch matching, and results showed that both musicians and nonmusicians were more accurate using the slider than their voices to match target pitches, arguing against a perceptual explanation of singing deficits. Experiment 2 added a self-matching condition and showed that nonmusicians were better at matching their own voice than a synthesized voice timbre, but were still not as accurate as on the slider. This suggests a timbral translation type of mapping error. Experiments 3 and 4 demonstrated that singers do not improve over multiple sung responses, or with the aid of a visual representation of pitch. Experiment 5 showed that listeners were more accurate at perceiving the pitch of the synthesized tones than actual voice tones. The pattern of results across experiments demonstrates multiple possible causes of poor singing, and attributes most of the problem to poor motor control and timbral-translation errors, rather than a purely perceptual deficit, as other studies have suggested.     

“If it's in your mind,it's in your knowledge”: Children's developing anatomy of identity

Recent work has investigated children's developing understanding of the anatomical locus of identity. In two studies, we extend this work by exploring the role of the mind as opposed to the brain in children's conceptualization of identity. In Experiment 1, an analysis of natural language indicated that adults use the term mind more frequently than the term brain with reference to identity-related mental processes. Children's output displayed a similar bias. In Experiment 2, we compared the judgments of 5- and 7-year-old children to those displayed by adults. Participants heard stories in which a magical transformation resulted in either a creature with a mismatch between brain and body or a creature with a mismatch between mind and body. Children were more accurate in recognizing the enduring identity of this transformed creature when the transformation resulted in a mismatch between mind and body as compared to brain and body.     

General ecological information supports engagement with affordances for ‘higher’ cognition

Synthese - In this paper, we address the question of how an agent can guide its behavior with respect to aspects of the sociomaterial environment that are not sensorily present. A simple example is...     

Do the colors of your letters depend on your language? Language-dependent and universal influences on grapheme-color synesthesia in seven languages

Grapheme-color synesthetes experience graphemes as having a consistent color (e.g., “N is turquoise”). Synesthetes’ specific associations (which letter is which color) are often influenced by linguistic properties such as phonetic similarity, color terms (“Y is yellow”), and semantic associations (“D is for dog and dogs are brown”). However, most studies of synesthesia use only English-speaking synesthetes. Here, we measure the effect of color terms, semantic associations, and non-linguistic shape-color associations on synesthetic associations in Dutch, English, Greek, Japanese, Korean, Russian, and Spanish. The effect size of linguistic influences (color terms, semantic associations) differed significantly between languages. In contrast, the effect size of non-linguistic influences (shape-color associations), which we predicted to be universal, indeed did not differ between languages. We conclude that language matters (outcomes are influenced by the synesthete’s language) and that synesthesia offers an exceptional opportunity to study influences on letter representations in different languages.     

How challenging was your work today? The role of autonomous work motivation

The main aim of this study was to investigate whether autonomous motivation for work can explain the distinctive associations between hindrance and challenge demands and work-related well-being (i.e., positive affect and work engagement) on a within-person level. Autonomous work motivation represents the degree to which motivation for putting effort in work is intrinsic (i.e., with a sense of volition and personal choice) or has been internalized (i.e., without feelings of internal or external pressure). In order to test our hypotheses, we employed a diary methodology and followed 153 secondary school teachers throughout five consecutive working days. The results of multilevel modelling provided support for the hypothesized research model. On days when teachers experienced more challenges, they also experienced more positive affect and more engagement in their work on the same day, and this relationship could be explained by (higher) autonomous work motivation on that day. In contrast, on days when teachers experienced more hindrance demands, they experienced less positive affect and less work engagement, and this process was explained by (reduced) autonomous work motivation that day. Our findings add to the literature by showing that daily autonomous motivation as a motivational process can explain why daily challenge and hindrance demands are differentially related to positive well-being at work.     

“Clean up your plate”: Effects of child feeding practices on the conditioning of meal size

To obtain information on the development of the learned control of food intake, preschool children (N = 22) participated in conditioning and extinction trials to determine whether meal size could be conditioned. Each trial consisted of a two-part snack in which consumption of a fixed amount of a distinctively flavored high (145 kcal) or low (60 kcal) caloric density preload was followed by ad lib consumption of snacks. Following the pairs of conditioning trials, extinction test trials were given in which the flavors previously paired with either high or low caloric density were presented in intermediate, isocaloric preloads. Conditioning occurred in one of two child feeding contexts: one that focused children on internal cues of hunger and satiety, or one that focused the children on external cues, including the amount of food remaining on the plate. The external group also could receive rewards for eating. Only the children in the internal context showed evidence of responsiveness to caloric density cues and associative conditioning, eating more ad lib following the low-density preload than following the high density preload during conditioning, and eating more during extinction following the flavor previously paired with low caloric density. Children in the external context showed no evidence of responsiveness to caloric density cues, but increased in ad lib consumption across the conditioning trials.     

Is it in your face?: Exploring the effects of sexual dimorphism on perception of leadership potential

Perceptions of a leader in a work environment is important from 2 perspectives: the leader themselves and more importantly the external observer. But what information does the observer use when making these judgments of leadership potential? Many studies on role congruity have demonstrated that gender stereotyping and perceived leadership ability is strongly tied to gender role incongruity. The role of facial appearance has been associated with leadership status and potential and becomes essentially relevant in military settings. Thus, the manner in which an individual’s face is perceived and evaluated may impact perceptions of his or her leadership ability and subsequent success. The present study seeks to extend research on how sex and gender characteristics of an individual’s face may possibly influence the perception of leadership abilities in a military service academy. Findings indicated that participants preferred individuals with gender congruent faces, which may reflect a preference for physical prowess and abilities.     

Exploratory behaviors and recalibration: What processes are shared between functionally similar affordances?

Recalibration of affordance perception allows observers to adapt to changes in the body’s size or abilities that alter possibilities for action. Of key interest is understanding how exploratory behaviors lead to successful recalibration. The present study was designed to test a novel hypothesis—that the same processes of exploration and recalibration should generalize between affordances that share a similar function. Most affordances for fitting the body through openings are recalibrated without feedback from practicing the action; locomotion exploration is sufficient. The present study used a different fitting task, squeezing through doorways, to determine whether locomotor experience was sufficient for recalibrating to changes in body size that altered affordances. Participants were unable to recalibrate from locomotor experience, demonstrating that exploratory behaviors do not necessarily generalize between functionally similar affordances. Participants only recalibrated following action practice or after receiving feedback about judgment accuracy, suggesting that the informational requirements of the squeezing task may differ from those of other fitting tasks. Implications for affordance theory are discussed.     

Can mindfulness modify your thoughts? A study in the context of social phobia

IntroductionSocial phobia is said to be the commonest anxiety disorder (Furmark, 2002). Cognitive Behavior Therapy appears to be the most recommended form of psychological treatment for this condition (Federoff & Taylor, 2001; Willutzki et al., 2012). Dismantling studies have raised doubts regarding the utility of cognitive restructuring in bringing about decrease in symptoms (Barrera et al., 2016; Pompoli et al., 2018). Mindfulness, a ‘third-wave’ concept, seems to contradict the philosophy of ‘restructuring’ with its apparent stress on non-judgmental observation (Hayes, 2004). This approach postulates that acceptance of cognitions and emotions as therapeutic in contrast to traditional cognitive behavior therapy approach, which advocates restructuring and modifications of cognitions.ObjectiveThe current study attempted to study the ‘restructuring’ effects of mindfulness in persons with social phobia.MethodThirty-nine clients with a primary diagnosis of social phobia (ICD – 10) participated in the Mindfulness Integrated Cognitive Behavior Therapy (MICBT) program, which consisted of eight sessions. MINI International Neuropsychiatry Interview Plus, Liebowitz Social Anxiety Scale, Fear of Negative Evaluation, Meta Cognitions Questionnaire and Five-Facet Mindfulness Questionnaire were administered pre and post of the therapeutic program.ResultsThe results demonstrated that MICBT had a significant effect on reducing the scores on fear of negative evaluation and bringing about changes in metacognitions.ConclusionMindfulness could be sufficient as a therapeutic strategy to bring about changes in the cognitions of clients with social phobia without using cognitive restructuring.     

Where did you park your car? Analysis of a naturalistic long-term recency effect

Abstract

Three experiments studied the long-term retention of parking locations. In Experiment 1, members of the Applied Psychology Unit (MU) attempted to recall where they had parked during the morning and afternoon of each of the previous 12 working days. A marked recency effect was observed. In Experiment 2, members of the APU Subject Panel were invited for a single test session, and asked where they had parked after a delay of 2 hours, 1 week or 1 month. Recall was excellent and did not differ as a function of delay, allowing a simple trace decay interpretation to be ruled out. A third experiment invited subjects to attend on two occasions separated by a 2-week interval. The subjects were then required to recall their parking locations some 4 weeks after either their first visit or their second visit. Performance in both groups was inferior to that observed in Experiment 2, and declined over time. A temporal discrimination model, based on laboratory studies of both long-term and short-term recency in free recall, offers a plausible explanation of our results.     

Accurate by way of aggregation: Should you trust your intuition-based first impressions?

How much should you trust your intuition about other people's job performance? Different literatures provide different answers to this question. Social psychological research on “thin slices” suggests that untrained observers can predict a person's job performance based on a few moments of observation. Industrial/organizational psychologists have found a weaker relationship between job performance and the intuitive judgments that people make following employment interviews. This paper argues that interviewers' intuitive judgments appear to be weaker predictors than intuitive judgments of thin slices because thin slices research measures predictive validity at the aggregate-level of analysis. Intuition-based first impressions will not usually be valid predictors of job performance unless people have an opportunity to collect and combine the judgments of multiple independent raters.     

What is it to be aware of your awareness of red? A review essay of Michelle Montague’s The Given

In this review essay of Michelle Montague’s The Given we focus on the central thesis in the book: the awareness of awareness thesis. On that thesis, a state of awareness constitutively involves an awareness of itself. In Section 2, we discuss what the awareness of awareness thesis amounts to, how it contrasts with the transparency of experience, and how it might be motivated. In Section 3, we discuss one of Montague’s two theoretical arguments for the awareness of awareness thesis. A view that accepts the awareness of awareness thesis, Montague argues, is to be preferred over competing views because it outperforms them in accounting for the property attributions one makes in perceptual experience. We suggest that it is not clear that this argument for the awareness of awareness thesis is successful. Finally, in Section 4 we consider the relation between Montague’s view of color experience and what she calls Strawson’s datum, arguing that Montague may not be able to explain this datum as straightforwardly as she supposes. This, we suggest, threatens Montague’s second theoretical argument for the awareness of awareness thesis.     

Can I see your passport please? Perceptual discrimination of own- and other-race faces

Psychological research has consistently demonstrated that individuals are better at discriminating faces of their own race when compared with faces of another, less familiar race. Given the racial/ethnic diversity of individuals screened by security personnel at transportation and border checkpoints, it is important to understand whether the cross-race effect may play a role in simultaneous perceptual discrimination tasks that mimic such screening operations. Three experiments assessed the deleterious effects of cross-racial identification in this context. Results demonstrated greater discrimination accuracy for own- versus other-race faces, and a propensity for screeners to be overconfident in their decisions, particularly for other-race persons. Further, perceived age differences between the target and his identification photo and the use of a disguise were found to moderate cross-race effects during this task.
