Identification,Meaning, and the Normativity of Social Roles

Abstract: We are all familiar with the way in which social roles, such as mother, father, professor, club football coach, citizen, and so on, confront us with clusters of duties that purport to bind us. Though we generally experience these role‐duties as normatively binding, we might question this. What reason do role‐occupants have for conforming to the duties that define their roles? I argue that the agent who identifies with her role thereby has a weighty and important justificatory reason for conforming to the role's defining duties: namely, the identifying agent realizes the fundamental goods of meaning and self‐determination by doing so. This is an important normative ground of role‐duties because it, unlike the grounds of natural duty or voluntary assumption, ensures that the duties it grounds are not alien impositions but rather are elements of the identifying agent's wellbeing. I also argue that role‐identification provides a reason that shares many of the characteristics of a moral reason, and I argue that role‐identification in tandem with the principle of fair play grounds a moral duty to conform to one's role‐duties.     

Shifting spatial attention makes you flip: Exogenous visual attention triggers perceptual alternations during binocular rivalry

Although it has been argued that visual attention and the dynamics of binocular rivalry are closely linked, strong evidence for this proposition is still lacking. Here, we investigate how perceptual alternations during binocular rivalry are affected by spatial attention by employing a cuing paradigm. We show a tight link between the occurrence of perceptual alternations and the spatiotemporal properties of visual attention: Alternations occurred earlier and more frequently at locations where visual attention was summoned by an exogenous cue. We argue that cuing a location where rival images are presented leads to a transient increase in the effective contrast of these rival images. This transient increase in effective contrast increases the probability of an alternation at that location. Furthermore, we suggest that an occipito-fronto-parietal network known to be involved in selective attention and binocular rivalry mediates perceptual alternations by boosting the neural response at attended locations.     

Implicit and explicit self-esteem in the context of internet addiction

Previous research has repeatedly found that people suffering from some clinical disorders (e.g., bulimia nervosa, depression) possess low explicit (i.e., conscious, deliberate) self-esteem while at the same time displaying high implicit (i.e., unconscious, automatic) self-esteem. This phenomenon has been termed damaged self-esteem and was proposed to be an indicator of psychological distress. Although Internet addiction has been found to be associated with low levels of explicit self-esteem, as well as with high levels of psychological distress, its relation to implicit self-esteem has, to our knowledge, not been investigated thus far. We therefore hypothesized that the phenomenon of damaged self-esteem could also be found amongst people suffering from Internet addiction, and conducted two studies using the Initial Preference Task as a measure of implicit self-esteem. As expected, we found that individuals scoring high on Internet addiction possess low explicit and high implicit self-esteem. This effect was, however, only found for the first name initial of the Initial Preference Task, leading to the conclusion that first and last name initials might tap into different parts of implicit self-esteem.     

Temporal information processing and pitch discrimination as predictors of general intelligence.

In the present study, the relationship between performance on temporal and pitch discrimination and psychometric intelligence was investigated in a sample of 164 participants by means of an experimental dissociation paradigm. Performance on both temporal and pitch discrimination was substantially related to psychometric intelligence (r=.43 and r =.39). Regression analysis and structural equation modeling suggested that both psychophysical domains can be considered as valid predictors of psychometric intelligence. Both predictor variables contributed substantial portions of both shared and unique variance to the prediction of individual differences in psychometric intelligence. Thus, the present study yielded further evidence for a functional relationship between psychometric intelligence and temporal as well as pitch discrimination acuity. Eventually, findings are consistent with the notion that temporal discrimination - in addition to general aspects of sensory discrimination shared with pitch discrimination reflects specific intelligence-related aspects of neural information processing.     

Sex differences in face recognition and influence of facial affect

To study sex differences in the recognition of human faces with different facial expressions, 65 female and 64 male participants learned to associate names with various male and female neutral faces. During the recall phase, participants were then asked to name the same persons depicting different emotional expressions (neutral, happy, angry, and fearful). Females were faster than males at naming male faces, and males were faster than females at naming female faces. All participants were faster at naming neutral or happy female faces than neural or happy male faces. These results suggest that opposite-sex faces require less processing time than same-sex faces, which is consistent with an evolutionary account.     

Control beliefs and susceptibility to the promises of memory improvement

Brain training is increasingly popular, and many believe in the efficacy of such programs without empirical evidence. We examined whether instructions promising memory improvement would influence subjective and objective cognition. Participants (n = 145; age: M = 50.64) were randomly assigned to a memory improvement or memory task condition. Participants completed demographic and perceived control over cognition measures, in addition to cognitive tasks and subjective cognition items for 7 days. Participants in the improvement condition reported significantly greater memory increases than those in the memory task condition. This effect was moderated by perceived control over cognition; participants in the improvement condition with high control beliefs were significantly more likely than those with low control beliefs or those in the task condition to report better memory. Individuals with higher control beliefs may be more susceptible to the claims of brain training programs, which is significant given that such programs are increasingly popular and commercially available.     

“From war to peace”: Military festival visitors’ quality-of-life

The Voortrekker Monument Military festival is one of several military festivals held in South Africa. This study sought to determine the travel motives and life domain effects on the quality-of-life of visitors. Data were gathered from 330 visitors on their travel motives, overall life domains, and quality-of-life. Structural Equation Modelling analysis indicated a positive linear relationship between the visitors’ travel motives, life domains (social-life, leisure-life, and self-life), life domains overall, and quality-of-life; all of which attained good reliabilities. The findings indicate that a visit to a military heritage festival has a positive effect on visitors’ quality-of-life. This research adds to literature in the social sciences, positive psychology, and quality-of-life.     

Two types of serial dependence in visual working memory

Stimulus representations in working memory depend on memory traces of past stimuli both from previous trials and from the current trial. However, it is unclear whether the same or different mechanisms underlie this serial dependence across and within trials. We directly contrasted estimates of bias for pairs of immediately successive stimuli across and within trials. In each trial, participants memorized two consecutive motion direction stimuli (S1 and S2) and after a short delay were cued to report one of them. We found serial dependence across trials: The current S1 was attracted towards the preceding S2 when the latter had been cued for report. In contrast, within the same trial S2 was repulsed from S1. In addition, repulsion within a trial occurred for a broader range of motion direction differences between stimuli than attraction across trials. A second experiment in which 25% of trials did not require a response demonstrated that across‐trial attraction did not depend on whether the previous S2 actually had to be reported. Our findings provide evidence for two types of serial dependence operating across and within trials. They support the notion of different mechanisms integrating or segregating current from similar past memory contents depending on their task relevance.
