Disentangling trait from state components in the assessment of egoistic and moralistic self-enhancement

A latent state-trait model has been used to assess the extent to which egoistic and moralistic self-enhancement represent: (a) stable individual differences and (b) systematic effects of the situation and/or the person-situation interaction. Analyses were conducted on a sample of 187 adults (64% females). Findings revealed that both self-enhancement tendencies mostly capture stable interindividual differences, although significant occasion-specific effects were observed. Egoistic self-enhancement presents a higher proportion of trait variance than moralistic self-enhancement. The egoistic dimension was mostly related with the stable (trait) components of conscientiousness and emotional stability. The moralistic dimension, on the contrary, was mostly related with the transient component of emotional stability. Potential explanations for the observed differences between egoistic and moralistic self-enhancement were discussed and interpreted in terms of their implications for personality assessment.     

The selective relationship between religious dimensions and social desirability among Polish students

This study explores the effect of the position of the religious construct-system (central vs. subordinated vs. marginal) in personality on the relationship between social desirability and structure of religiosity, emotion to God and post-critical belief. The sample comprised Polish Students (N?=?200) aged between 19 and 29 years. The Social Desirability Scale, The Structure-of-Religiosity Test and The Post-Critical Belief Scale were employed in the study. The results suggest that religiosity is not associated with social desirability.     

The Limits of Attention for Visual Perception and Action in Aging

ABSTRACT

This study aimed to investigate whether aging results in an increased attentional blink effect in older adults as compared to young adults. A rapid serial visual presentation (RSVP) paradigm was employed in which participants were asked to identify two targets (dual-task condition) presented in rapid succession. These targets were separated by various intervals in a stream of stimuli. The performance for identifying the second target was normally diminished as compared to identification of a single-task target. Various combinations of tasks, such as two perceptual tasks or one perceptual and one action task, as well as different types of pointing action, such as pointing to a displaced target, pointing to a stationary target or pointing to a disappeared target, were manipulated in this study to see if aging may further impact these variables. The results of this study showed that in young adults, successful identification of the first target interfered with identifying the second target, as well as the initiation time (action planning) of pointing to the second target. However, identification of the first target did not interfere with pointing movement time and pointing accuracy, even when the target was displaced, which required online control of action. Conversely, for older adults, successful central identification not only interfered with identifying the second target and with the pointing initiation time, but also interfered with pointing movement time for a displaced target. This suggests that older adults seem to be unable to concurrently identify the first target and correct their already-initiated pointing movement compared to young adults.     

Sensorimotor fluency influences affect: Evidence from electromyography

Fluency of visual processing induces affective responses, with easier-to-process stimuli being preferred (Winkielman & Cacioppo, 2001). The present study extends this research to the motor domain by investigating the effect of sensorimotor fluency on affective reactions to objects in a categorisation task. In fluent stimulus–response (s–r) trials, grasp-compatible objects were presented on the same side of the screen as the response hand; in non-fluent trials, grasp incompatible objects were presented on the opposite side of the screen to the response hand. Affective responses were measured implicitly using face muscle activity (electromyography). As predicted, participants exhibited greater cheek muscle activity (associated with smiling) in trials with s–r compatible responses compared with incompatible responses. These findings support hedonic models of fluency in which fluent processing elicits direct emotional experience, and suggest that models of hedonic fluency should take into account the integration of the motor system in visual processing.     

Affect-congruent approach and withdrawal movements of happy and angry faces facilitate affective categorisation

Increasing evidence indicates that evaluation of affective stimuli facilitates the execution of affect-congruent approach and avoidance responses, and vice versa. These effects are proposed to be mediated by increases or decreases in the relative distance to the stimulus, due to the participant's action. In a series of experiments we investigated whether stimulus categorisation is similarly influenced when changes in this relative distance are due to movement of the stimulus instead of movements by the participant. Participants responded to happy and angry faces that appeared to approach (move towards) or withdraw (move away) from them. In line with previous findings, affective categorisation was facilitated when the movement was congruent with stimulus valence, resulting in faster and more correct responses to approaching happy and withdrawing angry faces. These findings suggest that relative distance indeed plays a crucial role in approach–avoidance congruency effects, and that these effects do not depend on the execution of movements by the participant.     

The nucleus basalis and memory codes: auditory cortical plasticity and the induction of specific, associative behavioral memory

Receptive field (RF) plasticity develops in the primary auditory cortex (ACx) when a tone conditioned stimulus (CS) becomes associated with an appetitive or aversive unconditioned stimulus (US). This prototypical stimulus-stimulus (S-S) association is accompanied by shifts of frequency tuning of neurons toward or to the frequency of the CS such that the area of best tuning of the CS frequency is increased in the tonotopic representation of the ACx. RF plasticity has all of the major characteristics of behavioral associative memory: it is highly specific, discriminative, rapidly induced, consolidates (becomes stronger and more specific over hours to days) and can be retained indefinitely (tested to two months). Substitution of nucleus basalis (NB) stimulation for a US induces the same associative RF plasticity, and this requires the engagement of muscarinic receptors in the ACx. Pairing a tone with NB stimulation actually induces specific, associative behavioral memory, as indexed by post-training frequency generalization gradients. The degree of acquired behavioral significance of sounds appears to be encoded by the number of neurons that become retuned in the ACx to that acoustic stimulus, the greater the importance, the greater the number of re-tuned cells. This memory code has recently been supported by direct neurobehavioral tests. In toto, these findings support the view that specific, learned auditory memory content is stored in the ACx, and further that this storage of information during learning and the instantiation of the memory code involves the engagement of the nucleus basalis and its release of acetylcholine into target structures, particularly the cerebral cortex.     

Norwegian short-form of the Marlowe-Crowne Social Desirability Scale

A tutorial example demonstrates the effects of social desirability bias on fictional multiculturalism and mental health data and how bias can be moderated by parital correlations using social desirabiliry measures of different degrees of validity. The 33-item Marlowe-Crowne Social Desirability scale was translated from English to Norwegian and presented to 117 university students and 124 non-students. Using psychometric criteria, and a "seed-crystal" method accretion, a 10-item Norwegian short-form of the Marlowe-Crowne scale was produced.     

Cross-Informant Agreement in the Assessment of Social Phobia in Youth

In the present study involving children and adolescents with a principal diagnosis of social phobia, we measured parent–child agreement regarding social anxiety symptoms. Additionally, we examined variables related to the severity of the children's social phobia symptoms as reported by children and as rated by clinicians. Examination of cross-informant agreement indicated little difference between mean parent and children ratings of the children's social fears. In contrast, there was a significant difference in parent and children ratings of the children's avoidance, with parents endorsing greater degrees of social avoidance. Children's report of social avoidance was negatively related to scores on a measure of self-presentational concerns (i.e., social desirability). Clinicians' determination of the severity of the children's social phobia was also influenced by the children's self-presentation as well as parent report of social avoidance and children's depression scores. Thus, this differential weighting by the clinician of parent versus child report may be related to the finding that children's self-reported social avoidance was negatively related to their concerns regarding positive self-presentation. Results suggest the need to consider the impact of social desirability when examining clinical characteristics of children and adolescents with social phobia.     

Delayed N2 response in Go condition in a visual Go/Nogo ERP study in children who stutter

Purpose of the studyThe main aim of the study was to investigate the attentional and inhibitory abilities and their underlying processes of children who stutter by using behavioural measurement and event-related potentials (ERP) in a visual Go/Nogo paradigm.MethodsParticipants were 11 children who stutter (CWS; mean age 8.1, age range 6.3–9.5 years) and 19 typically developed children (TDC; mean age 8.1, age range 5.8–9.6 years). They performed a visual Go/Nogo task with simultaneous EEG recording to obtain ERP responses.ResultsResults showed that CWS had longer N2 and P3 latencies in the Go condition compared to the TDC. In contrast, the groups did not differ significantly in the Nogo condition or behavioural measures.ConclusionsOur findings did not confirm less efficient inhibitory control in CWS but suggest atypical attentional processing such as stimulus evaluation and response selection.Educational Objectives: The reader will be able to (a) describe recent findings on attention and inhibitory control in children who stutter, (b) describe the measurement of attentional processing, including inhibitory control, and (c) describe the findings on attentional processing in children who stutter as indexed by the event-related potentials in a visual Go/Nogo paradigm.     

Perception of Sentence Stress in Speech Correlates With the Temporal Unpredictability of Prosodic Features

Numerous studies have examined the acoustic correlates of sentential stress and its underlying linguistic functionality. However, the mechanism that connects stress cues to the listener's attentional processing has remained unclear. Also, the learnability versus innateness of stress perception has not been widely discussed. In this work, we introduce a novel perspective to the study of sentential stress and put forward the hypothesis that perceived sentence stress in speech is related to the unpredictability of prosodic features, thereby capturing the attention of the listener. As predictability is based on the statistical structure of the speech input, the hypothesis also suggests that stress perception is a result of general statistical learning mechanisms. To study this idea, computational simulations are performed where temporal prosodic trajectories are modeled with an n‐gram model. Probabilities of the feature trajectories are subsequently evaluated on a set of novel utterances and compared to human perception of stress. The results show that the low‐probability regions of F0 and energy trajectories are strongly correlated with stress perception, giving support to the idea that attention and unpredictability of sensory stimulus are mutually connected.
