Social influence of a coworker: A test of the effect of employee and coworker exchange ideologies on employees’ exchange qualities

Integrating social comparison and social influence perspective within a social exchange theoretical framework, we examine how the exchange ideologies of employees and their coworkers affect the quality of the employees’ social exchanges. Drawing from social exchange theory, we hypothesize that the exchange ideology of a focal employee has a negative relationship with the quality of his/her social exchange with the organization (i.e., felt obligation) and the quality of his/her social exchange with a leader (i.e., leader–member exchange), both of which are related to task performance. Furthermore, we propose that a coworker close to the employee acts as a social referent and provides cues to exert influence on these relationships. Using data collected from 374 (employee–coworker–manager) triads in Hong Kong, we find support for the aforementioned relationships as well as the moderating roles of a coworker’s exchange ideology.     

Patterns in parent–child conversations about animals at a marine science center

Parent-child conversations are a potential source of children's developing understanding of the biological domain. We investigated patterns in parent-child conversations that may inform children about biological domain boundaries. At a marine science center exhibit, we compared parent-child talk about typical sea animals with faces (fish) with talk about atypical sea animals without faces (e.g., sea stars), in particular with respect to anthropomorphic talk and use of animate pronouns. Parents talked about psychological states and used animate pronouns more often for typical than atypical animals; children showed a similar pattern for pronouns but did not differ in their property talk between typical and atypical animals. It was clearly parents who initiated the use of psychological properties and animate pronouns for typical animals. These patterns suggest that parent-child conversations draw boundaries between typical and atypical animals and could support children's inclination to anthropomorphize.     

Infants’ reasoning about ambiguous motion events: The role of spatiotemporal and dispositional status information

Two experiments investigate whether 7-month-olds reason about the origin of motion events by considering two sources of causally relevant information: spatiotemporal cues and dispositional status information derived from the identification of an object as either animate (with the enduring causal property of self-initiated motion) or inanimate (requiring an external cause of motion). Infants were shown a ball, a human hand, and an animal engaged in a motion event. While dispositional status information remained constant, spatiotemporal relations varied across conditions. Based on looking time data, we conclude that infants attend flexibly to both types of information. Without spatiotemporal cues, infants rely on dispositional status information. When two objects provide dispositional cues to motion origin, but only one also provides corresponding spatiotemporal information, infants attribute the motion to the object providing both types of information. Given an ambiguous motion event with two dispositional motion originators but no additional spatiotemporal cues, infants may prefer either of the two.     

Developmental differences in shape processing

Considerable evidence indicates that shape similarity plays a major role in object recognition, identification and categorization. However, little is known about shape processing and its development. Across four experiments, we addressed two related questions. First, what makes objects similar in shape? Second, how does the processing of shape similarity develop? We specifically asked whether children and adults determine shape similarity by using categories (e.g., straight vs. curved), as proposed by Biederman (1987), or whether they treat all shape variability uniformly, as proposed by Ullman (1998). Findings from Experiments 1 and 2 suggest that adults and 7-year-olds generally engage in a process in which they impose categories on shape variation and judge objects that fall within those categories as being similar in shape. Four-year-olds are far less likely to engage in such a process. Experiments 3 and 4 address whether 4-year-olds are more likely to treat shape similarity categorically (as older children and adults do) when the objects are given familiar names, functions, and internal properties. Naming did lead to more advanced treatment of shape similarity in some cases. Overall, these findings provide evidence of developmental differences in shape processing and suggest that knowledge of abstract properties of objects may affect the calculation of shape similarity.     

Justice sensitivity and the processing of justice‐related information

We investigated how Justice Sensitivity (JS) shapes the processing of justice‐related information. We proposed that due to frequently perceiving and ruminating about injustices, persons high in JS develop highly accessible and differentiated injustice concepts that shape attention, interpretation and memory for justice‐related information. Three studies provided evidence for these assumptions. After witnessing injustice, persons high in JS attended more strongly to unjust stimuli than to negative control stimuli (Study1) and interpreted an ambiguous situation as less just than persons low in JS (Study2). Finally, they displayed a memory advantage for unjust information (Study3). Results suggest that JS involves the availability and accessibility of injustice concepts as parameters of cognitive functioning and offer explanations for effects of JS on justice‐related behaviour.

Educational privilege: The role of school context in the development just world beliefs among Brazilian adolescents

The purpose of this study is to understand the development of Brazilian adolescents' justice perceptions across different contexts of educational privilege. Past research has found that, in adolescence, the belief in a just world (BJW) differentiates between personal and general and declines. However, prior research has not included adolescents from various socioeconomic statuses, samples in Latin America, or focused on the role of the educational context on the developmental trajectory. Participants were 385 adolescents from 3 schools (private, public and military) in Southern Brazil between 9th and 11th grade. Students completed the personal and general BJW survey. Results revealed a significant interaction of school and grade level of adolescents' personal BJW. Contrary to previous research, personal and general BJW was not always lower in higher grades. Among privileged educational contexts, data indicated that personal BJW may even increase, with the decrease notable in the lower resourced school. In contrast, general BJW was relatively consistent across all Brazilian adolescents. Results provide important insight into the role that privilege and education play across adolescents' development of BJW. This research questions the generalizability of previous studies on the development of BJW and indicates that the trajectory may be dependent upon educational and cultural context.     

Is positive thinking in anticipation of a performance situation better than distraction? An experimental study in preadolescents

The current study compares the effects of experimentally induced positive anticipatory thinking and distraction in preadolescents aged 12–13. Eighty‐seven participants were instructed to either engage in positive anticipatory thoughts or perform a distraction task while preparing to perform a sporting activity in front of their peers. Results revealed that trait social anxiety was associated with more negative estimates of sport performance and catastrophic thoughts relating to the impending sport activity. Additionally, compared to children who distracted, children in the positive anticipation condition showed significantly increased anxiety levels, more catastrophic thoughts and more negative predictions of sport performance and appearance, although these effects did not appear to interact with trait social anxiety. Finally, no significant manipulation effect on participants’ observable behavior was found. The findings further highlight the utility of distracting from an impending, anxiety‐provoking situation to keep anxious feelings to a low level.     

Perceptual influences of error size on voluntary force control during a compound sinusoidal force task

Visual feedback that provides error information is critical to task quality and motor adjustments. This study investigated how the size of perceived errors via visual feedback affected rate control and force gradation strategy of a designate force task. Fourteen young adults coupled force exertions to a compound sinusoidal signal (0.2 Hz and 0.5 Hz) that fluctuated around a mean level of 30% of maximal voluntary contraction, when the size of execution errors were differently scaled with the error amplification factors. In the low (LAF) and high (HAF) amplification factor conditions, the execution errors in the visual display half and double of the real errors, respectively. The visualized error was the real errors in the medium amplification factor (MAF) condition. In addition to a phase-lead of force output, the LAF condition that virtually reduced the size of error feedback associated with a poorer task accuracy than the MAF and HAF conditions. Virtual increase in error size of visual feedback selectively suppressed the fast target force at 0.5 Hz. In addition, complexity and high-frequency components (>0.75 Hz) of force outputs multiplied progressively with increasing error size. Error-enhancing feedback suppressed fast target force, accentuating the use of error information to tune force output, whereas error-reducing feedback enhanced fast target force in favor of predictive force control.     

The association between ruminative thinking and negative interpretation bias in social anxiety

Cognitive models propose that both, negative interpretations of ambiguous social situations and ruminative thoughts about social events contribute to the maintenance of social anxiety disorder. It has further been postulated that ruminative thoughts fuel biased negative interpretations, however, evidence is rare. The present study used a multi-method approach to assess ruminative processing following a social interaction (post-event processing by self-report questionnaire and social rumination by experience sampling method) and negative interpretation bias (via two separate tasks) in a student sample (n?=?51) screened for high (HSA) and low social anxiety (LSA). Results support the hypothesis that group differences in negative interpretations of ambiguous social situations in HSAs vs. LSAs are mediated by higher levels of post-event processing assessed in the questionnaire. Exploratory analyses highlight the potential role of comorbid depressive symptoms. The current findings help to advance the understanding of the association between two cognitive processes involved in social anxiety and stress the importance of ruminative post-event processing.     

Differential emotion attribution to neutral faces of own and other races

Past research has demonstrated differential recognition of emotion on faces of different races. This paper reports the first study to explore differential emotion attribution to neutral faces of different races. Chinese and Caucasian adults viewed a series of Chinese and Caucasian neutral faces and judged their outward facial expression: neutral, positive, or negative. The results showed that both Chinese and Caucasian viewers perceived more Chinese faces than Caucasian faces as neutral. Nevertheless, Chinese viewers attributed positive emotion to Caucasian faces more than to Chinese faces, whereas Caucasian viewers attributed negative emotion to Caucasian faces more than to Chinese faces. Moreover, Chinese viewers attributed negative and neutral emotion to the faces of both races without significant difference in frequency, whereas Caucasian viewers mostly attributed neutral emotion to the faces. These differences between Chinese and Caucasian viewers may be due to differential visual experience, culture, racial stereotype, or expectation of the experiment. We also used eye tracking among the Chinese participants to explore the relationship between face-processing strategy and emotion attribution to neutral faces. The results showed that the interaction between emotion attribution and face race was significant on face-processing strategy, such as fixation proportion on eyes and saccade amplitude. Additionally, pupil size during processing Caucasian faces was larger than during processing Chinese faces.
