Influence of perceived emotion and gender on social motor coordination

Theorists have long postulated that facial properties such as emotion and sex are potent social stimuli that influence how individuals act. Yet extant scientific findings were mainly derived from investigations on the prompt motor response upon the presentation of affective stimuli, which were mostly delivered by means of pictures, videos, or text. A theoretical question remains unaddressed concerning how the perception of emotion and sex would modulate the dynamics of a continuous coordinated behaviour. Conceived in the framework of dynamical approach to interpersonal motor coordination, the present study aimed to address this question by adopting the coupled-oscillators paradigm. Twenty-one participants performed in-phase and anti-phase coordination with two avatars (male and female) displaying three emotional expressions (neutral, happy, and angry) at different frequencies (100% and 150% of the participant's preferred frequency) by executing horizontal rhythmic left-right oscillatory movements. Time to initiate movement (TIM), mean relative phase error (MnRP), and standard deviation of relative phase (SDRP) were calculated as indices of reaction time, deviation from the intended pattern of coordination, and coordination stability, respectively. Results showed that in anti-phase condition at 150% frequency, MnRP was lower with the angry and the female avatar. In addition, coordination was found to be more stable with the male avatar than the female one when both displaying neutral emotion. But the happy female avatar was found to elicit more stable coordination than the neutral female avatar. These results implied that individuals are more relaxed to coordinate with the female than the male, and the sensorimotor system becomes more flexible to coordinate with an angry person. It is also suggested social roles influence how people coordinate, and individuals attend more to interact with a happy female. In sum, the present study evidenced that social perception is embodied in the interactive behaviour during social interaction.     

Latina adolescents: predicting intentions to have sex

This study utilized the theory of reasoned action to examine how Latina adolescents' intentions to have sex in the coming month were influenced by their general attitude toward having sex and their perceptions of general social norms about having sex. Eighty-four Mexican American and Central American adolescent females ages 14 to 19 participated in telephone interviews. One group of 41 Mexican American adolescents was obtained through a telephone survey and the second group of 43 pregnant or parenting Mexican American and Central American adolescents was recruited from health clinics. Path analysis conducted separately for the two groups indicated that, for the clinic group, perceptions of general social norms, but not general attitude, predicted intentions to have sex; and for the survey group, whether they were sexually active directly predicted perceptions of general social norms and intention to have sex. Adolescents' perceptions of what significant others desired of them, but not their motivation to comply, predicted perceptions of general social norms about having sex. Results underscore the importance of social norms for Latina adolescents when they are considering whether or not to have sex.     

Bias in visual attention behavior in a normal school-aged population

Hemi-field visual-spatial attention was studied on a timed letter cancellation task in proficient readers from 7th to 9th grades. Participants maintained greater accuracy in identifying targets in the left quadrants (top/bottom) when compared with the right quadrants (top/bottom), revealing a leftward bias in their responses. Effects of gender and age were evident on performance; females scored significantly higher than males, and 9th graders scored significantly higher than 7th and 8th graders. Thus, a substantial shift in brain maturation may take place from 8th to 9th grades or from the ages of 13.0 to 14.11. Discriminative characteristics of the task are analyzed by assigning greater value to targets located in the top left quadrant. The 9th graders, as compared to the younger students, and the girls, as compared to the boys, evidenced a reading-direction-related bias toward systematic preference for the upper-left to lower-right quadrants.     

Language Anxiety and Counseling Self‐Efficacy

A total of 120 master's‐level counseling students were given the Foreign Language Classroom Anxiety Scale and the Counselor Self‐Estimate Inventory. Significance was found for all 3 hypotheses: (a) nonnative English‐speaking students have significantly more language anxiety than native English‐speaking students, (b) nonnative English‐speaking students’ language anxiety was negatively correlated with counseling self‐efficacy, and (c) native English‐ and nonnative English‐speaking students significantly differed in their perceptions of counseling self‐efficacy. Se administraron la Escala de Ansiedad en Clase de Lengua Extranjera y el Inventario de Autoestimación de Consejeros a un total de 120 estudiantes de máster en consejería. Se encontró significación para las 3 hipótesis siguientes: (a) los estudiantes cuya lengua nativa no es el inglés sufren un nivel considerablemente más alto de ansiedad a causa del idioma que los hablantes nativos de inglés, (b) la ansiedad a causa del idioma de los estudiantes cuya lengua nativa no es el inglés mostró una correlación negativa con la autoeficacia en consejería y (c) los grupos de estudiantes nativos y no nativos en inglés mostraron diferencias significativas en sus percepciones de autoeficacia en consejería.     

Crossmodal transfer of arousal, but not pleasantness, from the musical to the visual domain

Arousal and valence (pleasantness) are considered primary dimensions of emotion. However, the degree to which these dimensions interact in emotional processing across sensory modalities is poorly understood. We addressed this issue by applying a crossmodal priming paradigm in which auditory primes (Romantic piano solo music) varying in arousal and/or pleasantness were sequentially paired with visual targets (IAPS pictures). In Experiment 1, the emotion spaces of 120 primes and 120 targets were explored separately in addition to the effects of musical training and gender. Thirty-two participants rated their felt pleasantness and arousal in response to primes and targets on equivalent rating scales as well as their familiarity with the stimuli. Musical training was associated with elevated familiarity ratings for high-arousing music and a trend for elevated arousal ratings, especially in response to unpleasant musical stimuli. Males reported higher arousal than females for pleasant visual stimuli. In Experiment 2, 40 nonmusicians rated their felt arousal and pleasantness in response to 20 visual targets after listening to 80 musical primes. Arousal associated with the musical primes modulated felt arousal in response to visual targets, yet no such transfer of pleasantness was observed between the two modalities. Experiment 3 sought to rule out the possibility of any order effect of the subjective ratings, and responses of 14 nonmusicians replicated results of Experiment 2. This study demonstrates the effectiveness of the crossmodal priming paradigm in basic research on musical emotions.     

How social and non-social information influence classification decisions: A computational modelling approach

Social information such as observing others can improve performance in decision making. In particular, social information has been shown to be useful when finding the best solution on one’s own is difficult, costly, or dangerous. However, past research suggests that when making decisions people do not always consider other people’s behaviour when it is at odds with their own experiences. Furthermore, the cognitive processes guiding the integration of social information with individual experiences are still under debate. Here, we conducted two experiments to test whether information about other persons’ behaviour influenced people’s decisions in a classification task. Furthermore, we examined how social information is integrated with individual learning experiences by testing different computational models. Our results show that social information had a small but reliable influence on people’s classifications. The best computational model suggests that in categorization people first make up their own mind based on the non-social information, which is then updated by the social information.     

Rumination and self-reflection in stress narratives and relations to psychological functioning

The longitudinal study aims to expand what is known about the costs and benefits of narrating stressful experiences by exploring changes in rumination within the narrative process and comparing it to changes in self-reflection. Rumination (e.g., brooding, self-criticism, and negative emotions) and self-reflection were measured in stress narratives of 56 college students. There were several goals: (1) examine changes in narrative rumination and narrative self-reflection over 3 days of writing, (2) examine the relations among the changes in narrative rumination variables and narrative self-reflection and (3) examine how changes in narrative rumination and narrative self-reflection relate to multiple measures of psychological functioning. Overall, individuals increased self-reflection over the 3-day writing task. Individuals who increased ruminative brooding across the 3 days of writing showed lower ego identity development (short term and long term) and self-esteem (short term), while increased self-criticism was positively correlated with identity distress (short term). Implications of the different aspects of narrative rumination, specifically in the context of stressful experiences, are discussed.     

Disconfirming Expectations: Incorrect Imprecise (vs. Precise) Estimates Increase Source Trustworthiness and Consumer Loyalty

Estimations that include numerical information are ubiquitous in our daily lives, for example, housing prices, calories, etc. In the present work, we investigate how the type of information used in an estimate, particularly its level of imprecision, influences evaluations of source trustworthiness after the target value of the estimate is revealed. Specifically, building upon prior work suggesting that (a) imprecise estimates are perceived to be less accurate than precise estimates and (b) performing below expectations results in negative source evaluations, we hypothesize that if the estimate is revealed to be incorrect, imprecise estimates (i.e., 400) elicit higher source trustworthiness than precise estimates (i.e., 417), even if the imprecise estimate is objectively more incorrect (i.e., target value: 570). In addition, we find that this effect also influences consumers’ loyalty toward the source of the estimate. Four studies and a single‐paper meta‐analysis offer triangulating evidence for this prediction and its underlying psychological mechanism. Overall, this work contributes to research on estimates, source evaluations, numerical information, and the influence of errors on consumer behavior.     

Interruption of phonological coding in conduction aphasia

A case study of conduction aphasia, investigating single word repetition, phonological coding, and short-term memory, is reported. Evidence from intact adults suggests that repetition can occur through either a lexical route or a direct auditory-articulatory link. For this conduction aphasic, E.A., the direct link was impaired, although the lexical route could be used to produce accurate single word repetition. Several experiments demonstrated a significant impairment in the generation and maintenance of an abstract phonological code. The consequences of a disruption of phonological coding on speech perception and on verbal short-term memory are discussed.     

An analysis of speech perception in word deafness

A patient with a rather pure word deafness showed extreme suppression of right ear signals under dichotic conditions, suggesting that speech signals were being processed in the right hemisphere. Systematic errors in the identification and discrimination of natural and synthetic stop consonants further indicated that speech sounds were not being processed in the normal manner. Auditory comprehension improved considerably however, when the range of speech stimuli was limited by contextual constraints. Possible implications for the mechanism of word deafness are discussed.
