Agreement by design: The effect of visual harmony on responses to surveys

The present study is one of the first to empirically examine how the visual harmony of a questionnaire can lead to measurement bias. Researchers often employ questionnaires with Likert scales to measure constructs. In this note, we examine how the design of the survey instrument, specifically, its visual harmony, can impair measurement accuracy. Two studies investigate effects of visual harmony in surveys on responses to Likert scales using paper and pencil surveys. Applying an established customer relationship management model, Study 1 employs a survey of female visitors to a grocery store (n = 115). Switching to a product and brand innovation context, Study 2 employs a survey of male and female members of a consumer panel (n = 180) to examine responses to a new e‐scooter. Across studies, results indicate that assessing important consumer response constructs through visually more harmonious surveys can lead to more positive response patterns, lower scale reliability, and questionable validity, especially with females. Although these effects do not occur uniformly across measures and samples, they occur regardless of consumers' past experience with completing questionnaires, their familiarity with questionnaire design, and the naturalness and elaborateness of the visual design. Relating specific elements (e.g., text boxes, type font, shapes, and images) and relational properties of design (e.g., balance, symmetry, and coherence) to consumers' overall perception of harmony aids marketers and researchers in achieving intermediate levels to obtain realistic, reliable, and valid results.     

Context and Complexity in Incremental Sentence Interpretation: An ERP Study on Temporal Quantification

The present event-related potential (ERP) study used picture–sentence verification to investigate the neurolinguistic correlates of the online processing of compositional-semantic information. To this end, we examined context effects on sentences involving temporal adverbial quantification likeJana war jeden Morgen schwimmen an den Arbeitstagen (“Jana went for a swim every morning during the working week”). We tested whether the conceptual complexity associated with quantifying over time intervals leads to delayed predictions regarding the upcoming words in a sentence. The present study replicated previous results relating to quantification over individuals, which are conceptually less complex than time intervals. Analogous to previous studies, false vs. true sentences elicited an N400 whenever contextual cues did not permit a potential revision of a locally assigned truth value. The present results are compatible with an approach under which contextual cues are immediately considered for predicting how a sentence continues. The fact that the contextual complexity did not lead to processing delays indicates that the processing system quickly abstracts away from the conceptual complexity associated with the linguistic input if such an abstraction is possible.     

Sex differences in early verbal and non‐verbal cognitive development

The present study of over 3000 2‐year‐old twin pairs used a sex‐limitation model to examine genetic and environmental origins of sex differences in verbal and non‐verbal cognitive ability. Girls scored significantly higher on both measures (p<0.0001), although gender only accounted for approximately 3% of the variance in verbal ability and 1% of the variance in non‐verbal cognitive ability. For the verbal measure boys showed greater heritability than girls. Also the twin‐pair correlation is significantly lower for opposite‐sex twins than for non‐identical same‐sex twins. This indicates that individual differences in verbal ability include some sex‐specific factors. Non‐verbal cognitive ability did not differ in aetiology for boys and girls. We conclude that genetic and environmental influences differ for girls and boys for early verbal but not non‐verbal development.     

Using cognitive learning theory to design effective on-line statistics tutorials

Careful attention to principles of learning can improve the design of Web-based lessons and tutorials. Tutorials from the Web Interface for Statistics Education (WISE; http://wise.cgu.edu) demonstrate how specific principles can be integrated into Web design to enhance learning in two areas. First, the impact of students’ poor self-regulation abilities on Web-based learning is considered. Second, evidence that specific types of visual presentations improve learning is discussed. Finally, the need for empirical evaluation is emphasized. Specific research and examples from the WISE project are used to illustrate each of these points.     

Organizational Commitment in Nepalese Settings

This study examines the three-dimensional organizational commitment (OC) concept (Meyer & Allen, 1997) in Nepal. Standardized questionnaires were administered to a heterogeneous sample of 103 employees of four different Nepalese organizations (bank, food corporation, telecommunication, and an airline). Exploratory factor and confirmatory factor analyses replicate the dimensionality of OC, i.e., the three facets of commitment (affective, normative, and continuance commitment) could be found also in a developing country with a cultural background very different from the places where the commitment concept was originally formulated. Antecedents and consequences of organizational commitment were investigated by multiple regression analyses. Continuance and normative commitment were both explained by job characteristics, i.e., by the perception of the job as interesting, affective commitment could not be explained with the set of variables used in this study. However, it is affective commitment which particularly accounts for variance in search intentions as well as in turnover intentions.     

Bilateral coordination in human infants: stepping on a split-belt treadmill

A motorized treadmill often elicits locomotor-like alternate stepping in 7-month-old infants who normally perform few, if any, stepping movements. The step cycle duration is a function of the speed of the treadmill. When infants were held so that each leg was on a separate treadmill belt, each of which was driven at a different speed, the overall cycle duration was intermediate between the cycle durations at the fast or slow speeds alone. Infants shortened the stance on the slow belt and increased the stance on the fast belt to maintain regularly alternating steps. Even before voluntary locomotion, both legs acted in a cooperative manner, with the dynamic status of one limb affecting the timespace behavior of the opposite limb.     

Gender differences in perceived intimacy with different members of adolescents' social networks

Previous research has clearly established important gender differences in how intimacy is viewed within a narrow set of relationships, primarily those with same-sex peers. This article presents a new social pressures model that delineates a set of diverse forces believed to influence gender differences in intimacy across a much wider set of social relationships during early adolescence. Although it was impossible to examine the actual operation of the postulated pressures, an extensive data set on all the important people in the lives of over 2000 seventh- through tenth-grade white suburban adolescents made it possible to test a set of 22 hypotheses derived from the model. These hypotheses covered relationships with nuclear, extended family, and nonkin members of the social network who were of different ages and genders. Results indicated that, while gender differences in the perceived intimacy of relationships were widespread, they were neither present in all types of relationships nor were those found always in the same direction. Furthermore, the social pressures model developed accurately predicted both the location and direction of the gender differences across most of the 22 different types of relationships. Suggestions for an elaboration of the model are noted, along with additional research issues that need to be addressed.     

The Towers of Silence: creative and destructive issues for therapeutic teams dealing with sexual abuse

Intra-familial sexual abuse of children is a peculiarly potent area for subsequent inter-agency responses and interventions to become inappropriate, irrational, and damaging. A major component of the damaging responses by the inter-agency system is the mirroring processes which occur between that system and the family.
A case example is presented in some detail to illustrate the ways in which such mirroring processes also effect therapeutic teams dealing with such families. Some therapeutic techniques from an experiential base are described. It is argued that productive therapeutic work can only occur if the mirroring processes within the inter-agency system, and the therapeutic team system, are considered systemically.
