Perceptually Equivalent Judgments Made Visually and via Haptic Sensory-Substitution Devices

ABSTRACT

According to the ecological theory of perception–action, perception is primarily of affordances, which are directly perceivable opportunities for behavior. The current study evaluated participants’ ability to use vision and haptic sensory-substitution devices to support perceptual judgments of affordances involving the task of passing through apertures. Sighted participants made perceptual judgments about whether they could walk through apertures of various widths and their level of confidence in each judgment, using unrestricted vision and, when blindfolded, using two haptic sensory-substitution instruments: a cane-like wooden rod and the Enactive Torch, a device that converts distance information into vibrotactile stimuli. The boundary between aperture widths that were judged as pass-through-able versus non-pass-through-able was statistically equivalent across sensory modalities. However, participants were not as confident in their judgments using the rod or Enactive Torch as they were using vision. Additionally, participants’ judgments with the haptic instruments were significantly more accurate than with vision. The results underscore the need to assess sensory-substitution devices in the context of functional behaviors.     

Assessment of Interpersonal Influences on Adolescents: The Parent and Peer Influence Scale

Peer influence is a common topic of interest for parents, clinicians, and researchers, but results from research on the relative importance of parents’ versus peers’ influence on adolescents and young adults has been contradictory. For example, some research suggests that peer attitudes about school influences future academic aspirations, other research suggests that parents and peers differ on their level of influence based on topic (e.g., parents’ are the primary source of influence about moral issues), and other research suggests that peer-oriented children are a product of parental disregard. A reliable and valid measure of the relative strength of parent versus peer influence could enhance research in this area. As a result, the Parent and Peer Inventory Scale (PPI) was developed, which demonstrates strong reliability as well as face and concurrent validity. The PPI can be used both by researchers to address contradictions in the literature, as well as clinicians seeking to evaluate level of peer influence in a family.     

Exploring patient perspectives of prediabetes and diabetes severity: a qualitative study

Abstract

Objective: This qualitative study sought to identify and describe patients’ variant perceptions of disease severity after receiving a type 2 diabetes (T2DM) or prediabetes (preDM) diagnosis.

Design: Researchers interviewed 29 patients from two US medical centers to ascertain perceptions of severity. We used the constant comparative method from a grounded theory approach to identify themes from patients’ perspectives that inform their disease severity. This approach was used to help translate research to practice and ultimately identify intervention strategies informed by authentic experiences of preDM and T2DM patients.

Results: Perceptions of disease severity fell into two groups: high and low severity. Patients diagnosed with T2DM and preDM emerged in both groups and were comparative in terms of sample size, gender, and ethnic diversity. Several factors contributed to patients’ beliefs, including what they were told about the disease, observations from experiences within their own social network, and information from formal diabetes classes and their own research. The two perspectives diverged when patients described how their belief was informed by three thematic properties or personal factors: (i) fears; (ii) clinician communication; and (iii) social comparisons.

Conclusions: Beliefs about severity are influenced by patients’ fears, interactions with clinicians, and experiences within their social networks. These findings show that when interacting with patients with T2DM or preDM, clinicians should elicit patient perceptions of disease severity so they may then tailor the discussion to address these perceptions and help patients grasp the severity of these conditions.     

Beautiful faces in pain: Biases and accuracy in the perception of pain

Abstract

The impact of appearance-based information on judgments about the psychological functioning of pain patients was investigated. Video-tapes of low back pain patients experiencing pain were used as stimulus materials. Subjects viewed silent video clips and photographs of the patients' faces and made judgments about the functioning of these patients. These judgments were affected both by patient physical attractiveness and gender. Physically attractive patients and male patients were judged to be functioning better than physically unattractive and female patients. The judgments were reasonably described as biased because the perceived differences about patients varying in attractiveness and sex were not associated with measures of actual patient functioning.     

How Norms (Might) Guide Belief

Abstract

Belief normativism is roughly the view that judgments about beliefs are normative judgments. Kathrin Glüer and Åsa Wikforss (G&W) suggest that there are two ways one could defend this view: by appeal to what might be called ‘truth-norms’, or by appeal to what might be called ‘norms of rationality’ or ‘epistemic norms’. According to G&W, whichever way the normativist takes, she ends up being unable to account for the idea that the norms in question would guide belief formation. Plausibly, if belief normativism were true, the relevant norms would have to offer such guidance. I argue that G&W’s case against belief normativism is not successful. In section 1, I defend the idea that truth-norms can guide belief formation indirectly via epistemic norms. In section 2, I outline an account of how the epistemic norms might guide belief. Interestingly, this account may involve a commitment to a certain kind of expressivist view concerning judgments about epistemic norms.     

Rethinking Sellars’ Myth of the Given: From the Epistemological to the Modal Relevance of Givenness in Kant and Hegel

ABSTRACT

Here, I pursue consequences, for the interpretation of Sellars’ critique of the ‘Myth of the Given’, of separating the modal significance that Kant attributed to empirical intuition from the epistemological role it also played for him. It is argued that Kant’s approach to modality in the Critique of Pure Reason can best be understood as a transcendental variation on Leibniz’s earlier ‘possibilist’ approach that treated the actual world as just one of a variety of possible alternative worlds. In this context, empirical intuitions seem to work like the mythical Givens subject to Sellars’ critique. This Kantian possibilism is then contrasted with an ‘actualist’ alternative approach to modality found in the contemporary work of Robert Stalnaker, but also recognizable in Hegel. In particular, the role of immediate perceptual judgments in Hegel is likened to that played by ‘witness statements’ in Robert Stalnaker’s attempt to distinguish the logic of judgments about the actual world from those about its alternate possibilities.     

Big Five personality traits contribute to prosocial responses to others’ pain

ObjectivesTwo studies examined whether observers’ personality traits contribute to prosocial responses to others’ facial expression of pain. Experiment 1 examined the personality traits that could account for observers’ variability in estimating others’ pain intensity. Experiment 2 questioned to what extent the contribution of personality traits on inclination to help people in pain depend on observers’ beliefs about pain’ characteristics.Method59 (experiment 1) and 76 (experiment 2) participants observed to 3-D realistic synthetic face movements mobilizing action units of pain, in order to estimate others’ pain. In experiment 2, painful localizations (e.g., chest, hand) were also manipulated. In each experiment, Big Five personality traits were assessed.ResultsExperiment 1 revealed that agreeableness and conscientiousness contributed to observers’ pain estimates across the increase of facial expression intensity. Experiment 2 showed that conscientiousness contributed to observers’ judgments whatever pain’ characteristics. Neuroticism was only salient for pain referring to life-threatening pain.ConclusionProsocial response to others’ pain depends on agreeableness, conscientiousness and neuroticism. However, these links are modulated by the pain behavior elicited and observers’ belief about the characteristic of pain.     

Protecting Self-Image: The Rationalization of Cheating in an International Billiard League

ABSTRACT

The American Poolplayers Association, founded in 1979, is an international billiard league established in the United States, Canada, and Japan, with more than 250,000 members. The most difficult problem facing the American Poolplayers Association (APA)’s league operators is the deliberate cheating by the competing players. Players cheat to lower their skill level, allowing them to win more easily in important billiard matches such as the APA international championships. Qualitative interviews revealed that when asked about their cheating behavior, the players used all five “techniques of neutralization to rationalize their actions attempting to protect their self-image and to help insulate them from external judgments.     

The Right Stuff: Preschoolers Generalize Reliability Across Communicative Domains When Informants Show Semantic (Not Episodic) Knowledge

ABSTRACT

Although preschoolers have strong expectations about the pedagogical nature of pointing gestures (Csibra & Gergely, 2006), more recent work has shown that preschoolers prefer to use informants’ spoken language, not their pointing gestures, to make judgments about their reliability (Palmquist & Jaswal, 2015). Here, we explored children’s inferences about pointers using a standard selective trust paradigm. Specifically, we asked whether 4- and 5-year-olds generalize reliability across communicative domains (from pointing ability to speaking ability). We found that children preferred to make generalizations about pointers’ reliability when they had conveyed semantic, but not episodic, knowledge. Individual differences in theory of mind also predicted children’s willingness to make generalizations about pointers’ reliability. Both sets of results suggest that multiple factors (i.e., the type of knowledge an informant shares and individual differences in children’s cognitive development) affect whether preschoolers generalize others’ reliability across domains.     

Event justice and social entity justice: A cross-lagged analysis

IntroductionThe life of organizations is punctuated by a wide range of managerial decisions (e.g., hiring and selection procedure, performance appraisal, new working methods). Facing such events, employees evaluate the fairness of the situation experienced (event justice). They can also examine the fairness demonstrated by a specific entity, such as the organization or the supervisor (social entity justice). So far, little is known about how justice judgments about events vs. entities are related to each other, especially in a context of organizational change.ObjectiveBuilding on decision-making and organizational justice literature, we investigate the directionality of the causal relationships between event justice and social entity justice within a context of organizational change in a Belgian company (a significant reorganization at the level of the organization chart resulting in different changes for employees).MethodsWe used two samples (team leaders and executives) and realized a cross-lagged panel analysis with two measurement times.ResultsThe study shows that, in both samples, employees’ fairness perceptions about their organization (social entity justice) influence their interpretation of the fairness of subsequent events involving the organization (event justice).ConclusionBuilding and fostering a climate of justice is therefore of primary importance to organizations, since global fairness perceptions about the organization may help employees to perceive a specific event, such as an organizational change, as being fair.     

Calibration processes in a serial talent test

ObjectivesIn the beginning of serial evaluations, raters assess performances without knowledge about following performances. We assume that judges must observe a certain number of performances to calibrate their judgment scale, leading to systematic biases (avoidance of extreme judgments) in the beginning of judgment series. The present experiment investigates how many performance observations are necessary to calibrate internal judgment scales, leading to consistent judgments.DesignA between-group design was used.MethodVideos of a talent-test were presented in different orders. Every performance was presented in early, medium, and late positions. Thirty participants rated these series and we assessed the effect of performance position on performance evaluations.ResultsWe found calibration biases within the first nine performances; after that, evaluations remained stable and consistent.ConclusionCalibration processes are completed after a specific number of judgments; this implies interesting interventions for consistent judgments independent of the position in a series.     

Ethics,Identity and the Boundaries of the Person

Abstract

Ethical theories and theories of the person constrain each other, in that a proposition about the person may be a reason for or against an ethical proposition, and conversely. An important class of such propositions about the person concern the boundaries of the person. These boundaries enclose a person's defining properties, which constitute his identity. A person's identity may partly determine and partly be determined by his ethical judgments. An equilibrium between one's identity and one's ethical judgments is the counterpart, at the personal level, of the philosophical ideal of reflective equilibrium between a theory of the person and an ethical theory.     

Defending internalists from acquired sociopaths

People who suffer brain damage to their ventromedial prefrontal cortex (VM patients) have a puzzling psychological profile: they seem to retain high intellect and practical reasoning skills after their brain injuries, but continually make poor decisions in many aspects of their lives. Adina Roskies argues that their behavior is explained by the fact that, although VM patients make correct judgments about what they ought to do, they are entirely unmotivated by those judgments. Roskies thus takes VM patients to be real-world counterexamples to motivational internalism: the thesis that, necessarily, if S judges that she ought to φ in circumstances C, then S is somewhat motivated to φ in C. In this paper, however, I argue that the neuropsychological evidence that Roskies appeals to does not actually show that VM patients are entirely unmotivated by their normative judgments. Rather, I argue, the evidence suggests that VM patients form weaker normative judgments than normals during practical deliberation. And this affords the internalist with a plausible explanation for VM patients’ behavior: because VM patients form weaker normative judgments than normals, they are less motivated by their normative judgments than normals, which allows their decision-making to be overruled by their standing desires for greater and more immediate rewards.     

Development and validation of a scale of social and moral judgments (ABB scale) and its use in prison settings

IntroductionThe traditional approach to value judgments involves determining the position of an individual on a scale designed to evaluate the underlying mechanisms and dimensions of judgments.ObjectiveThe purpose of this study was to develop and validate a scale among a general population and to apply it to individuals particularly affected by, or directly involved in, acts of transgression.MethodThe scale comprises three types of behavior involving an expression of personal values (atypism or idiosyncratic behavior) or a violation of moral or conventional standards. Subjects were asked to assess a range of actions and behaviors on three dimensions (Likert format): seriousness, excusability and rejection of the transgressor.Results and conclusionAs predicted, factor analysis shows a clear hierarchy of values. The results demonstrate the multidimensional nature of the instrument and indicate good reliability. Tolerance and severity indices were developed to understand the underlying dynamics of social and moral judgments. The study found that inmates’ judgments of violations and transgressions differed in some respects from the judgments made by the general population. The influence of context and the role of group membership as an explanatory factor are examined from the point of view of the identity strategies used.     

Effect of motorcycle lighting configurations on drivers’ perceptions of closing during nighttime driving

ObjectiveThe aims were to better understand how drivers perceive an approaching set of motorcycle headlights during nighttime driving and to determine whether alternative motorcycle headlight configurations improve drivers’ perceptual judgments of closing for an oncoming motorcycle.BackgroundMotorcyclists account for a disproportionate number of roadway fatalities, especially at night. One potential cause of this is drivers’ misjudgments of a motorcycle’s approach.MethodThe first experiment examined whether drivers were more sensitive to horizontal or vertical optical expansion and whether drivers could integrate these two dimensions to achieve a lower looming threshold. A second experiment built on these results to test whether alternative headlight configurations that maximized size were better than other motorcycle headlight configurations and a car’s headlights. In both experiments, participants were instructed to press a button to indicate when they first perceived an oncoming vehicle to be closing under nighttime driving conditions.ResultsHeadlight orientation did not affect when drivers perceived closing, and drivers were not able to integrate optical expansion from multiple dimensions in a way that achieves a lower looming threshold. However, the alternative motorcycle headlight configurations that accentuated the full extent of a motorcycle’s size resulted in drivers perceiving closing sooner than other motorcycle headlight configurations but not sooner than a car.ConclusionDrivers perceive closing sooner for larger headlight configurations except when the headlight configurations are relatively small, in which case the effect of headlight size is attenuated.ApplicationDrivers’ perceptual judgments of motorcycles may improve when motorcycles have headlights that span its full height.     

Social value and asymmetry of gender and sex categories in physical education

IntroductionSports are traditionally considered to be masculine activities, but recent studies have shown that femininity and women may be more highly valued in this domain than previously thought.ObjectiveThis study sought to elucidate the apparent ambivalence about women in sports and specifically examined the social value of gender and sex in physical education classes.MethodFrench physical education teachers from primary and middle schools and students in the fifth and ninth grades participated in two studies using the judge's paradigm and the self-presentation paradigm, respectively.ResultsThe first study indicated that both masculinity and femininity were valued by teachers but were differently anchored in the components of social value. While masculinity was associated with the likelihood of success (social utility), femininity was associated with likeableness (social desirability). The stereotype of “male superiority in sport” also modulated social utility judgments. The second study revealed that ninth graders presented themselves as highly feminine and masculine when they strove to gain approval. Fifth graders only used femininity as a self-presentation strategy, suggesting that at this age children do not yet attempt to conform to teachers’ expectations.ConclusionThese studies suggest that future research on stereotypes in sports would benefit from theoretical approaches that take ambivalence in personal judgments into account, as this would avoid misinterpreting null or counter-stereotypical effects as apparently positive.     

Moral Judgments of Aggressive and Nonaggressive Children

Abstract

Moral judgments were studied in 103 aggressive and 79 nonaggressive 10-year-old Finnish children. Their aggressiveness was evaluated by means of peer ratings. Moral judgments were assessed by presenting them with stories from their daily lives that contained moral conflicts. The results showed that the children did not adopt a constant level of moral reasoning; instead, judgments were situation specific. Furthermore, the moral cognitions of aggressive children did not differ from those of their nonaggressive peers, although sex-related differences tended to be significant: Boys adopted absolute moral standards, whereas girls' judgments were more relative.     

Student clinicians’ and clients’ perceptions of the therapeutic alliance and outcomes in stuttering treatment

PurposeThe purpose of this study was to examine how the therapeutic alliances (TA) of graduate student clinicians and adult clients who stutter relate to perceived treatment outcomes.MethodsStudent clinicians (N = 42) and adult clients who stutter (N = 22) completed a survey assessing their TA strength and perception of treatment outcomes. Responses were analyzed to determine similarities and differences in how clinicians and clients relate the TA to perceptions of treatment effectiveness, progress, and outcome satisfaction.ResultsResults suggest that clinicians and clients who stutter both relate the TA to treatment outcome, but in different ways. While clinicians associate the TA most with treatment effectiveness and client progress, clients relate the TA most to outcome satisfaction.ConclusionClinicians should be aware that for adult clients who stutter, outcome satisfaction is related to the degree of shared understanding, agreement on daily tasks, and bond they experience with their clinician. To ensure a strong TA and client satisfaction, clinicians should actively seek their clients’ perspective regarding TA status.
