Tests of Parallel Versus Integrated Structure in Polyrhythmic Tapping

Musically trained subjects tapped three beats with their right hand versus two beats with their left hand in synchrony with two corresponding tones. For independent groups of subjects, the pitch difference of the two tones was either small to encourage an integrated perceptual organization or large to encourage a streamed perceptual organization. Integrated versus parallel motor organization was tested by examining the pattern of covariances among intertap intervals. All subjects exhibited integrated motor organization. An integrated multiplicative hierarchical model of motor organization was superior to a serial chained model and to an independent hierarchical model in describing the pattern of covariances. The subjects who heard tones that encouraged an integrated percept performed with less variability than the subjects who heard tones that encouraged a streamed percept. This superior performance with an integrated motor organization and an integrated rather than a streamed perceptual organization is interpreted as evidence for temporal perceptual-motor compatibility.     

Malawian secondary students’ beliefs about intelligence

Students who view intelligence as malleable tend to be more academically motivated and perform at higher levels than students who view it as a fixed trait. We examined the beliefs of students from Malawi because the culture and schooling process in this country is very different from some other areas of the world in which students’ views of intelligence have already been studied. Our research questions were: (1) How do Malawian students define intelligence? (2) To what extent do Malawian students view intelligence as malleable? (3) Are Malawian students’ definitions of intelligence and beliefs about the malleability of intelligence similar to those of students in more developed countries? We conducted a mixed methods study and surveyed 136 students attending a secondary school in Malawi using a 39‐item questionnaire. Students responded to questions about their intelligence beliefs on open‐ and closed‐ended items. Our results showed that Malawian students believe that an intelligent student exhibits a variety of behaviors, including studying, working hard, reading, performing well on exams and in class, answering and asking questions, paying attention, and demonstrating good behavior. Most students believe that intelligence is malleable and provided responses that indicated that students can become more intelligent through effort. When compared to the findings of other studies, the present results suggest that the Malawian students who remain in secondary school have definitions of intelligence and beliefs about the malleability of intelligence that are similar to those of students in more developed countries, such as the US and Germany. In fact, it appears that Malawian secondary students have even higher malleable beliefs than American and German students. Finally, some of the measures that have been found to produce scores that are reliable and valid in other populations do not produce scores that are as reliable when used with Malawian students.     

The Mediating Effects of Facial Expression on Spatial Interference Between Gaze Direction and Gaze Location

Gaze direction is an important social cue that interacts with facial expression. Cañadas and Lupiáñez (2012) reported a reverse-congruency effect such that identification of gaze direction was faster when a face was presented to the left but with the eyes directed to the right, or vice versa. In two experiments, this effect is replicated and then extended to explore the relationship between this effect and facial expression. Results show that the reverse-congruency effect is replicable with speeded gaze-direction identification, and that the effect is mediated by facial expression. The reverse-congruency effect is similar for happy and angry faces, but was not found for fearful faces. Findings are discussed in relation to the similarity of processing of incongruent gaze direction and the processing of direct gaze.     

Influential Factors in Artist's Lives and Themes in Their Artwork

ABSTRACT: The purpose of this study was to investigate the relations among influential factors in artists' lives, the process of creativity, and themes in the resulting artwork. Both qualitative and quantitative methods were used. In Phase I of the research, 6 contemporary artists identified themes, influences, feelings, thoughts, and representations about 5 pieces of their own art. They also completed a 50-item survey about influential factors. Two judges also were asked to identify themes, influences, feelings, thoughts, and representations in Phase 2 of the research. The judges relied on 30 slides depicting the work of the 6 artists. The same 50-item survey concerning influential factors was completed by each of the judges while examining the slides a 2nd time. Hypothesis 1, which predicted that artists would articulate the events, experiences, and memories that have influenced their lives, was supported. Hypothesis 2, which predicted that artists would be aware of the relations between influential factors in their lives and specific themes, images, expressions, and representations in their paintings, also was supported. Hypothesis 3, which predicted that potentially influential factors would be communicated in the themes, images, expressions, and representations in artists' paintings, and that objective viewers can identify them, was supported partially. The judges responded similarly to at least 2 of the 5 pieces of art for each participant. Hypothesis 4, which predicted that influential themes would be similar across all participants ' paintings, also was supported partially. One hundred percent agreement was found for the strongest influences (e.g., loss and culture) when the men and the women were evaluated separately.     

Leader Behavior,Work-Attitudes,and Turnover of Salespeople: An Integrative Study

Data were collected from the national field sales force of a major consumer goods manufacturer. The study develops a structural model of salespeople's perceptions of their supervisors' behaviors (i.e., leadership consideration and leadership role clarity), and the influence of supervisors' behaviors on the sales force's role perceptions, job anxiety, job satisfaction, propensities to leave and actual turnover. The study integrates previous research regarding sales force turnover to form the underpinning for the relationships between the constructs, and finds empirically that sales managers' leadership behaviors directly and indirectly influence job satisfaction, which influences salespeople's propensity to leave the organization and actual turnover.     

Couple Communication as a Mediator Between Work–Family Conflict and Marital Satisfaction

Using a sample of married individuals employed full-time (N = 1,117), this study examined the mediating effects of constructive and destructive communication between partners on the relationship between work–family conflict and marital satisfaction. Results from structural equation modeling revealed that work–family conflict was significantly and negatively related to marital satisfaction. This relationship became insignificant when constructive and destructive communication were added to the model, evidence for full mediation. This was confirmed with Sobel’s test for mediation. Results suggest that teaching communcation skills may be a potent point of intervention for couples who experience high levels of work–family conflict.     

The Core of Darkness: Uncovering the Heart of the Dark Triad

The Dark Triad consists of three overlapping but distinct personality variables: narcissism, Machiavellianism and psychopathy. To date, however, no research has empirically identified what leads these three variables to overlap or whether other variables share the same core. The present research addresses why and how dark personalities overlap. Drawing from classic work in psychopathy, Hare's Factor 1 or manipulation and callousness were found to be the common antagonistic core. A series of latent variable procedures, including Multisample Structural Equation Models, revealed that for both samples, manipulation and callousness, completely accounted for the associations among the facet scores of the psychopathy, narcissism and Machiavellianism scales. Sample 2 also included Social Dominance Orientation, and results further confirmed that Social Dominance Orientation has the same common core as the Dark Triad. In sum, Hare's Factor 1—manipulation–callousness—emerged as common dark core that accounts for the overlap among antagonistic traits.

Numeracy as a Predictor of Adaptive Risky Decision Making

Numeracy or one's ability to appropriately process and use numerical information has been shown to be an important individual difference factor in decision making. The current study utilized a risky decision‐making task (called the “cups task”) in which choices are made to both earn and avoid losing hypothetical money. Critically, this design allowed investigators to examine numeracy‐related differences in adaptive decision‐making as measured by sensitivity to expected value (EV) differences over 54 paired‐choice trials—some in which it was advantageous to take a risk and some in which it was not. Results showed that in an undergraduate sample of 114 individuals, the less numerate took more risks and were less sensitive to varying EV levels than the more numerate, especially when it was disadvantageous to take a risk and when the choice involved a potential loss (rather than a gain). These results are consistent with a dual processing account in which the more numerate are much better than the less numerate at extracting the precise affective “gist” of the numerical information, which is then used to determine the goodness or badness of a particular choice.
