Something to smile about: The interrelationship between attractiveness and emotional expression

Previous studies have suggested a link between the processing of the emotional expression of a face and how attractive it appears. In two experiments we investigated the interrelationship between attractiveness and happiness. In Experiment 1 we presented morphed faces varying in attractiveness and happiness and asked participants to choose the more attractive of two simultaneously presented faces. In the second experiment we used the same stimuli as in Experiment 1 and asked participants to choose the happier face. The results of Experiment 1 revealed that the evaluation of attractiveness is strongly influenced by the intensity of a smile expressed on a face: A happy facial expression could even compensate for relative unattractiveness. Conversely, the findings of Experiment 2 showed that facial attractiveness also influences the evaluation of happiness: It was easier to choose the happier of two faces if the happier face was also more attractive. We discuss the interrelationship of happiness and attractiveness with regard to evolutionary relevance of positive affective status and rewarding effects.     

Women's advantage at remembering others' appearance: A systematic look at the why and when of a gender difference

Women recall the appearance of others better than men. The goal of the present research was to shed light on the explanations and boundary conditions of this gender difference. In three studies (592 participants), the authors tested potential mediators and moderators of the gender difference. Results corroborated the robustness of the gender difference. General task motivation, general memory ability, importance of appearance, appearance knowledge, attention paid to target, gazing at target, and communal or agentic orientation could not explain why women were better at recalling others' appearance than men were. Except for importance of appearance and appearance knowledge, which both decreased the magnitude of the gender difference, general task motivation, attention paid to target, length of exposure to target, delay in responding, cognitive load, and response format (verbal vs. nonverbal) had no effect on the gender difference. Results are discussed in relation to gender differences found in the nonverbal sensitivity literature.     

A first step toward cognitive remediation of voices: a case study

Several studies have shown that source-monitoring errors are related to verbal hallucinations in schizophrenia. An exploratory pilot study has been carried out to investigate the possibility of training patients in how to avoid errors in source-monitoring. One patient with paranoid schizophrenia and persistent thought insertions was trained for 6 hours to use mnemonic techniques to compensate specific deficits in source-monitoring. Results show that the patient was able to improve his performance and maintain the acquired progress at a 1-month follow-up assessment. These preliminary results are interesting for developing a larger controlled study of cognitive remediation of source-monitoring deficits.     

When looking back to nothing goes back to nothing

Previous research showed that the eyes revisit the location in which the stimulus has been encoded when visual or verbal information is retrieved from memory. A recent study showed that this behavior still occurs 1 week after encoding, suggesting that visual, spatial and linguistic information is tightly associated with the oculomotor trace and stored as an integrated memory representation. However, it is yet unclear whether looking behavior simply remains stable between encoding and recall or whether it changes over time in a more fine-tuned manner. Here, we investigate the time course of looking behavior during recall in multiple sessions across 1 week. Participants encoded visual objects presented in one of the four locations on the computer screen. In five sessions during the week after encoding, they performed on a visual memory recall task. During retrieval, participants looked back to the encoding location, but only in the recall sessions within 1 day of encoding. We discuss different explanations for the temporal dynamics of looking behavior during recall, searching for the role of eye movements in memory.     

Nonverbal self-accuracy in interpersonal interaction

Four studies measure participants' accuracy in remembering, without forewarning, their own nonverbal behavior after an interpersonal interaction. Self-accuracy for smiling, nodding, gazing, hand gesturing, and self-touching is scored by comparing the participants' recollections with coding based on videotape. Self-accuracy is above chance and of modest magnitude on average. Self-accuracy is greatest for smiling; intermediate for nodding, gazing, and gesturing; and lowest for self-touching. It is higher when participants focus attention away from the self (learning as much as possible about the partner, rearranging the furniture in the room, evaluating the partner, smiling and gazing at the partner) than when participants are more self-focused (getting acquainted, trying to make a good impression on the partner, being evaluated by the partner, engaging in more self-touching). The contributions of cognitive demand and affective state are discussed.     

Do self-statements enhance the effectiveness of virtual reality exposure therapy? A comparative evaluation in acrophobia.

There is a clear need for more detailed analysis of the role of cognitive self-statements in virtual reality exposure therapy (VRET). To date, no research on this topic has been done. The primary aim of this study was to investigate whether coping self-statements would enhance the effectiveness of VRET. In a randomized crossover design, 26 patients with acrophobia (DSM-IV diagnosis of specific phobia) were randomly assigned to two sessions of VRET followed by two sessions of VRET plus coping self-statements, or the other way around: first two sessions of VRET plus coping self-statements followed by two sessions of VRET. Results showed that VRET, regardless of addition of coping self-statements, decreased anxiety of heights, decreased avoidance of height situations, and improved attitudes towards heights. However, at 6-month follow-up, most gains during treatment were not fully retained.     

Time in the eye of the beholder: Gaze position reveals spatial-temporal associations during encoding and memory retrieval of future and past

Time is grounded in various ways, and previous studies point to a “mental time line” with past associated with the left, and future with the right side. In this study, we investigated whether spontaneous eye movements on a blank screen would follow a mental timeline during encoding, free recall, and recognition of past and future items. In all three stages of processing, gaze position was more rightward during future items compared to past items. Moreover, horizontal gaze position during encoding predicted horizontal gaze position during free recall and recognition. We conclude that mental time line and the stored gaze position during encoding assist memory retrieval of past versus future items. Our findings highlight the spatial nature of temporal representations.     

Dominance as Expressed and Inferred Through Speaking Time

Differences in speaking time during a group interaction are hypothesized to reflect differences in individual dominance. In order to test this assumption and to identify potential moderator variables influencing the strength of the predicted association, a meta‐analysis was conducted. Whether speaking time is used to convey dominance to the same extent that it is used in inferring dominance was tested by contrasting studies concerned with dominance expressed in speaking time with studies of inferred dominance based on speaking time. Overall, and for the investigated subcategories of studies, the relationship between dominance and speaking time was significant. The strength of the associations, however, differed considerably due to the influence of moderator variables. The results showed that inferred dominance studies showed stronger associations between speaking time and dominance as opposed to the expressed dominance studies. Additionally, if dominance was expressed due to dominance‐role assignments, the association between speaking time and dominance was stronger than if individuals with different levels of trait dominance interacted. For men, the association between speaking time and dominance was stronger than for women, and same‐gender groups showed stronger associations than opposite‐gender groups. Also, increasing group size intensified the strength of the association linearly.     

Automatic identification of storytelling responses to past-behavior interview questions via machine learning

Structured interviews often feature past-behavior questions, where applicants are asked to tell a story about past work experience. Applicants often experience difficulties producing such stories. Automatic analyses of applicant behavior in responding to past-behavior questions may constitute a basis for delivering feedback and thus helping them improve their performance. We used machine learning algorithms to predict storytelling in transcribed speech of participants responding to past-behavior questions in a simulated selection interview. Responses were coded as to whether they featured a story or not. For each story, utterances were also manually coded as to whether they described the situation, the task/action performed, or results obtained. The algorithms predicted whether a response features a story or not (best accuracy: 78%), as well as the count of situation, task/action, and response utterances. These findings contribute to better automatic identification of verbal responses to past-behavior questions and may support automatic provision of feedback to applicants about their interview performance.     

The World According to Men: It Is Hierarchical and Stereotypical

The present research was designed to test whether people who expect social relationships to be structured like pecking orders (interpersonal hierarchy expectation, IHE) are also prone to stereotyping and whether this relation is moderated by gender. In two studies, a total of 203 participants completed a self-report questionnaire on IHE (Interpersonal Hierarchy Expectation Scale, IHES) and either a questionnaire that measures a general tendency to stereotype (Acceptance of Stereotyping Questionnaire, ASQ, Study 1) or a projective measure that assesses the specific gender stereotype that low dominance positions are occupied by women and high dominance positions by men (Study 2). Results showed that both stereotyping measures were related to IHE, but only for men. Moreover, trait dominance did not mediate the relation between IHE and stereotyping.
