Do deaf individuals have better visual skills in the periphery? Evidence from processing facial attributes

ABSTRACT

Studies examining visual abilities in individuals with early auditory deprivation have reached mixed conclusions, with some finding congenital auditory deprivation and/or lifelong use of a visuospatial language improves specific visual skills and others failing to find substantial differences. A more consistent finding is enhanced peripheral vision and an increased ability to efficiently distribute attention to the visual periphery following auditory deprivation. However, the extent to which this applies to visual skills in general or to certain conspicuous stimuli, such as faces, in particular is unknown. We examined the perceptual resolution of peripheral vision in the deaf, testing various facial attributes typically associated with high-resolution scrutiny of foveal information processing. We compared performance in face-identification tasks to performance using non-face control stimuli. Although we found no enhanced perceptual representations in face identification, gender categorization, or eye gaze direction recognition tasks, fearful expressions showed greater resilience than happy or neutral ones to increasing eccentricities. In the absence of an alerting sound, the visual system of auditory deprived individuals may develop greater sensitivity to specific conspicuous stimuli as a compensatory mechanism. The results also suggest neural reorganization in the deaf in their opposite advantage of the right visual field in face identification tasks.     

“I see what you mean”: Oral deaf individuals benefit from speaker's gesturing

Recent studies in the psychological literature reveal that cospeech gestures facilitate the construction of an articulated mental model of an oral discourse by hearing individuals. In particular, they facilitate correct recollections and discourse-based inferences at the expense of memory for discourse verbatim. Do gestures accompanying an oral discourse facilitate the construction of a discourse model also by oral deaf individuals trained to lip-read? The atypical cognitive functioning of oral deaf individuals leads to this prediction. Experiments 1 and 2, each conducted on 16 oral deaf individuals, used a recollection task and confirmed the prediction. Experiment 3, conducted on 36 oral deaf individuals, confirmed the prediction using a recognition task.     

Do you see what I see? How social differences influence mindreading

Disagreeing with others about how to interpret a social interaction is a common occurrence. We often find ourselves offering divergent interpretations of others’ motives, intentions, beliefs, and emotions. Remarkably, philosophical accounts of how we understand others do not explain, or even attempt to explain such disagreements. I argue these disparities in social interpretation stem, in large part, from the effect of social categorization and our goals in social interactions, phenomena long studied by social psychologists. I argue we ought to expand our accounts of how we understand others in order to accommodate these data and explain how such profound disagreements arise amongst informed, rational, well-meaning individuals.     

Modality effects: Do they fall on deaf ears?

The present study tests the assumption of the PAS theory of echoic memory (Greene & Crowder, 1984) that the representation of acoustic features is necessary in producing modality effects. Performance by deaf subjects was compared to hearing subjects on serial and free-recall tasks with vocalizing and non-vocalizing conditions. For the serial tasks, typical modality and acoustic similarity effects were observed with hearing subjects, and no such effects were found with deaf subjects. However, for the free-recall task, modality effects were found for both deaf and hearing subjects. It is unlikely that phonological coding resulting from gestural cues mediates the modality effect, as phonological confusion errors for deaf and hearing subjects did not correlate with the size of this effect.     

Do humans prefer to see their grasping points?

ABSTRACT To grasp an object the digits need to be placed at suitable positions on its surface. The selection of such grasping points depends on several factors. Here the authors examined whether being able to see 1 of the selected grasping points is such a factor. Subjects grasped large cylinders or oriented blocks that would normally be grasped with the thumb continuously visible and the final part of the index finger's trajectory occluded by the object in question. An opaque screen that hid the thumb's usual grasping point was used to examine whether individuals would choose a grip that was oriented differently to maintain vision of the thumb's grasping point. A transparent screen was used as a control. Occluding the thumb's grasping point made subjects move more carefully (adopting a larger grip aperture) and choose a slightly different grip orientation. However, the change in grip orientation was much too small to keep the thumb visible. The authors conclude that humans do not particularly aim for visible grasping points.     

Machiavellian managers: Do they perform better?

This study investigates the relationship between Machiavellianism and job performance, as measured by sales per square foot, gross margin percentage, and inventory turnover, among 60 retail store managers. Except for a significant relationship between male store managers' gross margin percentage no other relationships were observed between Machiavellianism and job performance. Several explanations for the absence of significant relationships were discussed.     

Do conscientious individuals live longer? A quantitative review

OBJECTIVE: Following up on growing evidence that higher levels of conscientiousness are associated with greater health protection, the authors conducted a meta-analysis of the association between conscientiousness-related traits and longevity. DESIGN: Using a random-effects analysis model, the authors statistically combined 20 independent samples. In addition, the authors used fixed-effects analyses to examine specific facets of conscientiousness and study characteristics as potential moderators of this relationship. MAIN OUTCOME MEASURES: Effect sizes were computed for each individual sample as the correlation coefficient r, based on the relationship between conscientiousness and mortality risk (all-cause mortality risk, longevity, or length of survival). RESULTS: Higher levels of conscientiousness were significantly and positively related to longevity (r = .11, 95% confidence interval = .05-.17). Associations were strongest for the achievement (persistent, industrious) and order (organized, disciplined) facets of conscientiousness. CONCLUSION: Results strongly support the importance of conscientiousness-related traits to health across the life span. Future research and interventions should consider how individual differences in conscientiousness may cause and be shaped by health-relevant biopsychosocial events across many years.     

Do you see what I see? Co-actor posture modulates visual processing in joint tasks

ABSTRACT

Interacting with other people is a ubiquitous part of daily life. A complex set of processes enable our successful interactions with others. The present research was conducted to investigate how the processing of visual stimuli may be affected by the presence and the hand posture of a co-actor. Experiments conducted with participants acting alone have revealed that the distance from the stimulus to the hand of a participant can alter visual processing. In the main experiment of the present paper, we asked whether this posture-related source of visual bias persists when participants share the task with another person. The effect of personal and co-actor hand-proximity on visual processing was assessed through object-specific benefits to visual recognition in a task performed by two co-actors. Pairs of participants completed a joint visual recognition task and, across different blocks of trials, the position of their own hands and of their partner's hands varied relative to the stimuli. In contrast to control studies conducted with participants acting alone, an object-specific recognition benefit was found across all hand location conditions. These data suggest that visual processing is, in some cases, sensitive to the posture of a co-actor.     

Do 5-month-old infants see humans as material objects?

Infants expect objects to be solid and cohesive, and to move on continuous paths through space. In this study, we examine whether infants understand that human beings are material objects, subject to these same principles. We report that 5-month-old infants apply the constraint of continuous motion to inanimate blocks, but not to people. This suggests that young infants have two separate modes of construal: one for inanimate objects and another for humans.     

Do you see what I see? Infants’ reasoning about others’ incomplete perceptions

Twelve‐month‐olds realize that when an agent cannot see an object, her incomplete perceptions still guide her goal‐directed actions. What would happen if the agent had incomplete perceptions because she could see only one part of the object, for example one side of a screen? In the present research, 16‐month‐olds were first shown an agent who always pointed to a red object, as opposed to a black or a yellow object, suggesting that she preferred red over the other colours. Next, two screens were introduced while the agent was absent. The screens were (1) red or green on both sides; (2) red on the front (infants’ side) but green on the back (the agent’s side) or vice versa; or (3) only coloured red or green on the front. During test, the agent, who could see only the back of the screens, pointed to one of the two screens. The results revealed that while infants expected the agent to continue acting on her colour preference and point to the red rather than the green screen during test, they did so in accord with the agent’s perception of the screens, rather than their own perceptions: they expected the agent to point to the red screen in (1), but to the green‐front screen in (2), and they had no prediction of which screen the agent should point to in (3). The implications of the present findings for early psychological reasoning research are discussed.     

Height and attraction: Do men and women see eye-to-eye?1

Two experiments were conducted to examine the influence of male height on interpresonal attraction. In Experiment 1, short, medium, and tall women evaluated pictures of men whom they believed to be either short, medium, or tall. On the basis of previous research, it was predicted that women's attraction to the men would be an increasing linear function of the men's height. This prediction was not confirmed; men of medium height were seen to be significantly more socially desirable than either short or tall men. This was true whether the female evaluator was short, medium, or tall; women did not differ in their evaluations. In Experiment 2, short, medium, and tall men evaluated the same male stimuli the women had evaluated in Experiment 1. These men not only gave their own evaluation of the male stimuli, but they also estimated how socially desirable the males pictured were to women. While men showed no evidence that they believed height was important to women, their own evaluations revealed that they liked and rated short men more positively than they did tall men. This was true regardless of the height of the male rater. These results were discussed in terms of social stereotypes and the importance of specifying situational context in the prediction of attraction.     

Do you see what I see?: An exploration of inter-ethnic ideal body size comparisons among college women

The present study explored African American (n = 16) and European American (n = 19) college women's ideal body size perceptions for their own and the other ethnic group along with reasons behind their selections. Respondents completed an ethnically-neutral figure rating scale and then participated in ethnically-homogenous focus groups. European Americans mostly preferred a curvy-thin or athletic ideal body while most African American students resisted notions of a singular ideal body. European Americans suggested that African Americans’ larger ideal body sizes were based on greater body acceptance and the preferences of African American men. African Americans used extreme terms when discussing their perceptions of European Americans’ thin idealization, celebrity role models, and weight management behaviors. African Americans’ perceptions of European Americans’ body dissatisfaction were also attributed to the frequent fat talk they engaged in. Implications for promoting the psychosocial well-being of ethnically-diverse emerging adult females attending college are discussed.     

Do higher-class individuals feel more entitled? The role of system-justifying belief

ABSTRACT

Sense of entitlement can be defined as a pervasive sense that one deserves more and is entitled to more than others. Two studies examined the relationship between social class and sense of entitlement and how this relationship is moderated by system-justifying belief (SJB) in China. In Study 1, we conducted a survey among adults (N = 669) with results showing that social class was positively correlated with sense of entitlement for those endorsing SJB, but negatively correlated with sense of entitlement for those opposing SJB. In Study 2, we conducted an experiment among undergraduates (N = 128) with both social class and SJB being primed and the results replicated the pattern: the positive effect of primed higher social class on pay entitlement existed only for those primed with high SJB, and was dampened for those primed with low SJB. Therefore, higher-class individuals do not necessarily feel more entitled, and SJB may play an important role in shaping their sense of entitlement.     

Coping with human immunodeficiency virus: Do optimists fare better?

Individuals who test positive for human immunodeficiency virus (HIV) face a difficult adjustment task. It was hypothesized that those who were more optimistic would cope more effectively and experience less distress. Both general and health-specific measures of coping were used. Optimism and distraction were negatively related to state anxiety, whereas emotional preoccupation was positively related to state anxiety. Optimism was not a predictor of depression. Rather, distraction was negatively related to depression, whereas palliative coping, emotional preoccupation, and the interaction of palliative coping and optimism were positively related to depression. The mediation of optimism by coping variables indicated that emotion-oriented coping was a negative mediator of optimism on both state anxiety and depression. Distraction (which includes some social diversion content) was a mediator of the impact of optimism on depression.

Do Overgeneral Memories Make us feel better? An experimental examination

A critical assumption of the CaR-FA-X model, that overgeneral memory is partly attributable to the “functional avoidance” of specific details about one’s past experiences, has not been experimentally tested. Further, while it is assumed that the reinforcing properties of said avoidance leads to the emergence of an overgeneral recall style over time, this question has not been addressed developmentally. To explore these issues, two studies were conducted. In Study 1, 41 children and adolescents (M_age?=?12 years) were randomly assigned to recall overgeneral or specific negative memories on the Autobiographical Memory Test; participants later listened to their memories and provided pre- and post-tests of their emotional states at four time points: before and after memory generation and before and after memory exposure. In Study 2, 52 college-aged participants (M_age?=?19 years) completed the same protocol. Results indicated that children and adolescents in the overgeneral condition reported higher levels of positive affect relative to those in the specific condition, while recall condition did not impact adults’ emotional states. These findings were not explained by differences in emotion regulation strategies or psychopathological symptoms. Implications for developmental models of autobiographical memory and emotion regulation are discussed.     

Do sequence-space synaesthetes have better spatial imagery skills? Maybe not

Sequence-space synaesthesia is a type of visuo-spatial imagery in which numbers or calendar units are experienced to occupy locations in space. Previous studies have claimed that these synaesthetes (1) have stronger self-reported visual (but not spatial) imagery and (2) perform unusually well on mental rotation tasks that are usually taken to reflect spatial (but not visual) imagery. To further investigate whether this form of synaesthesia is related to spatial imagery, we compared synaesthetes to controls on the Object Spatial Imagery Questionnaire, a paper folding test and a mental rotation task. The synaesthetes did not differ from controls in self-reported spatial imagery, but showed a strong trend to report better visual imagery, replicating previously reported data patterns. Consistent with this, their paper folding and mental rotation performance was no better than controls. We also confirmed that, in our pooled sample, performance on both these tasks was positively correlated with self-reported spatial imagery. We suggest our data are more consistent with the view that sequence-space synaesthesia is related to visual than to spatial imagery, and we suggest reasons why previous studies may have found superior mental rotation performance.
