Disruption of comprehension by the meaning of irrelevant sound

This study investigates the claim that the disruption of comprehension by irrelevant sound is qualitatively different from that of short-term memory for order. Both meaningful and meaningless speech disrupted the comprehensive aspect of the task, but the effect of meaningful speech was significantly greater. Both rehearsal and semantic processing, which are involved in reading comprehension, seem to be susceptible to disruption by irrelevant meaningful speech. The study provides some evidence to suggest that the presence of meaning in the irrelevant sound in creases disruption of performance in cognitive tasks that also call upon processing of meaning.     

Category-specific enhancement of retrieval due to field perspective

Two memory perspectives have been distinguished: A field perspective where events are re-experienced in the first person, and an observer perspective where events are witnessed in the third person. Two experiments examined the influence of memory perspective on objective memory performance. In both experiments participants were presented with a series of verbal passages, each of which contained several different categories of information. For four of these categories (pertaining to affective reactions, physical sensations, psychological states, and associated ideas), recall was significantly higher when a field perspective was adopted than when an observer perspective was adopted, but for the five other categories (pertaining to physical actions, personal appearance, fine details, spatial relations, and peripheral details) there was no significant effect of perspective upon recall. The study is examined in the context of mental models and imagined episodic events.     

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.
